摘要： An inkjet print head having a dummy ink chamber and a dummy heater disposed in the inkjet print head such that air bubbles gathered at edges of an ink feed hole are pushed toward an inner side of the ink feed hole when inks are sprayed. Accordingly, although air bubbles caused by the air introduced from an exterior or separated from inks are gathered at the edges of the ink feed hole, the air bubbles are forcedly pushed toward the center portion of the ink feed hole communicating with an ink storage container such that the air bubbles can flow into the ink storage container. Thus, inks are easily supplied to ink chambers adjacent to the edges of the ink feed hole, so that missing nozzles can be prevented from being generated.
摘要翻译：一种喷墨打印头，其具有设置在喷墨打印头中的虚拟墨水室和虚拟加热器，使得当喷墨时聚集在墨水供给孔的边缘的气泡被推向墨水供给孔的内侧。因此，虽然由从外部引入的或与油墨分离的空气引起的气泡聚集在供墨孔的边缘处，但气泡被迫推向与墨水容器连通的供墨孔的中心部分，气泡可以流入储墨容器。因此，油墨容易地供应到与供墨孔的边缘相邻的油墨室，从而可以防止产生缺失的喷嘴。

摘要： Method for clarifying a carbonate process solution containing suspended insolubles which solution is used in the preparation of crystals selected from the group consisting of sodium bicarbonate, sodium sesquicarbonate, anhydrous sodium carbonate, and sodium carbonate monohydrate, which comprises dispersing in the carbonate process solution prior to crystallization a cationic flocculating agent comprising a substituted guar gum containing one quaternary ammonium group per 2 to 12 monosaccharide units to agglomerate the suspended insolubles so the suspended insolubles will readily settle out of the carbonate process solution.This invention relates to a process for clarifying a carbonate process solution used in the preparation of sodium bicarbonate, sodium sesquicarbonate, anhydrous sodium carbonate or sodium carbonate monohydrate crystals.In Sweetwater and adjacent counties in the vicinity of Green River, Wyoming, in the Green River formation extending into Colorado and Utah, as well as in other locations, crude ore deposits in the form of trona (Na.sub.2 CO.sub.3.sup.. NaHCO.sub.3.sup.. 2H.sub.2 0), nahcolite (NaHCO.sub.3), thermonatrite (Na.sub.2 CO.sub.3.sup.. H.sub.2 0), and dawsonite (NaAlCO.sub.3 (OH).sub.2) are found at various depths ranging from about 800 to about 1800 feet underground. These ore deposits are generally either found in beds separated by layers of shale or are found dispersed in lenses along with dawsonite and shale. Most of these crude ores, besides containing recoverable sodium carbonate values, also contain some sodium sulfate, sodium chloride, different percentages of insoluble and organic matter such as kerogenaceous material containing monocarboxylic acids, dicarboxylic acids, unsaturated acids, steroids and rosin acids. A typical analysis of crude trona from which the larger pieces of shale have been removed is:______________________________________ Constituent Percent ______________________________________ Na.sub.2 CO.sub.3 43.51 NaHCO.sub.3 36.11 H.sub.2 O 13.14 Na.sub.2 SO.sub.4 0.02 NaCl 0.08 Fe.sub.2 O.sub.3 0.14 Organic Matter 0.30 Insolubles 6.70 ______________________________________ Various processes have been proposed to prepare crystals of sodium bicarbonate, sodium sesquicarbonate, anhydrous sodium carbonate or sodium carbonate monohydrate from crude ores. One process for producing sodium carbonate from crude trona, known as the monohydrate process, is disclosed in U.S. Pat. No. 2,962,348 issued to Seglin et al on Nov. 29, 1960. In this process, crude trona, after being crushed and screened, is calcined directly to form crude sodium carbonate. The crude sodium carbonate is dissolved in an aqueous solvent to form a substantially saturated solution of crude sodium carbonate containing suspended insolubles consisting essentially of large coarse particles and insoluble solids comprising colloidal particles and insoluble particles which remain in suspension for long periods of time. The crude sodium carbonate solution is then clarified and/or filtered to remove most of the suspended insolubles. The clarified and/or filtered solution is then crystallized, preferably in multiple evaporative crystallizers to form sodium carbonate monohydrate crystals. The monohydrate crystals are then calcined to produce a dense, organic-free soda ash.Another process is the sesquicarbonate process, disclosed in U.S. Pat. Nos. 2,770,524 and 2,780,520. In this process, crude trona after being crushed and screened is dissolved in a hot recirculating mother liquor carrying more sodium carbonate than sodium bicarbonate so that the sodium carbonate and sodium bicarbonate in the mined trona is dissolved congruently. The suspended insolubles consisting of large coarse particles and attached thereto insoluble solids present in the solution are first settled out of the solution in clarifiers. The remainder of the insoluble solids are then removed by filtration. Sodium sesquicarbonate is then crystallized and separated from the hot solution and calcined to sodium carbonate. The mother liquor remaining after crystallization is reheated and returned to the dissolving tanks to dissolve more trona.When producing sodium carbonate in a commercial plant designed to produce 1,400 tons of sodium carbonate per day, a flow rate of approximately 1,200 gallons per minute of a carbonate process solution is required to pass through the dissolvers, clarifiers and crystallizers. With this high flow rate, it has been difficult to produce properly clarified solutions in the clarifiers. As a result, the clarifier overflow contains high amounts of insoluble solids necessitating the use of excessive amounts of filter aids or multiple filter stations to produce clear carbonate process solutions. Excessive filter loading has reduced the length of filter cycles between cleaning operations, and requires frequent filter washings with the concomitant discard of carbonate process solutions contained in the filter. These insoluble solids comprising colloidal particles and insoluble particles which remain in suspension for long periods of time, if not removed prior to crystallization, interfere with crystal growth during crystallization. Crystal growth is modified to such an extent that when the crystals are calcined to sodium carbonate they produce a fine particle size material having limited utility which material is consequently not readily saleable.Various attempts have been made to remove the insoluble solids from carbonate process solutions. British Patent 1,211,984 and U.S. Pat. No. 3,725,014 broadly disclose adding flocculants to carbonate process solutions containing undissolved grit and mud to assist in the coagulation and settling of insoluble solids. U.S. Pat. No. 3,486,844 discloses the use of a water-soluble carbohydrate gum as a flocculating agent to obtain the desired settling rate of the insolubles. U.S. Pat. No. 3,084,026 discloses the use of hydrophylic colloids as flocculating agents to flocculate, settle and remove colloidal fines from carbonate process solutions.An improved method has been unexpectedly discovered for clarifying a carbonate process solution used in the preparation of crystals selected from the group consisting of sodium bicarbonate, sodium sesquicarbonate, anhydrous sodium carbonate, and sodium carbonate monohydrate, which comprises forming a carbonate process solution containing suspended insolubles and a material selected from the group consisting of sodium carbonate and sodium bicarbonate; dispersing in the carbonate process solution about 1 to about 20 ppm of a cationic flocculating agent comprising a substituted guar gum containing 1 quaternary ammonium group per 2 to 12 monosaccharide units; agglomerating the suspended insolubles by forming agglomerated particles of increased size and density; settling and removing the agglomerating particles from the carbonate process solution; and crystallizing the clarified carbonate process solution to produce crystals selected from the group consisting of sodium bicarbonate, sodium sesquicarbonate, anhydrous sodium carbonate and sodium carbonate monohydrate.The phrase "carbonate process solution," as used herein refers to aqueous solutions containing at least sodium carbonate and/or sodium bicarbonate, from which solution crystals of sodium bicarbonate, sodium sesquicarbonate, anhydrous sodium carbonate, and sodium carbonate monohydrate can be obtained as the stable crystal phase and can be recovered from the mother liquor. The carbonate process solution is preferably derived from trona, even though it may also be derived from other natural minerals such as nahcolite, thermonatrite, and dawsonite. The carbonate process solution is prepared by conventional procedures well known in the prior art, including the typical trona processing process discussed herein.
