摘要： PROBLEM TO BE SOLVED: To provide a method for producing a molding having adequate properties by dehydrating a generated stuff from a manufacturing process etc., in a form of dust, sludge, or the like and by molding the same. SOLUTION: The process for mixing a plurality of kinds of powders in the form of dust, sludge, or slurry comprises preparing the slurry by controlling the moisture of the powder within a prescribed range in a mixing tank, and transferring the slurry to a thickening tank, where the slurry is mixed with a coagulating agent to form a thickened slurry. The thickened slurry is dehydrated by a dehydrator to produce a dehydrated matter, which is molded by an extrusion process through an extruding die. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To smoothly open and close a net panel, and increase the service life thereof by suppressing damage thereto. SOLUTION: Two lines of guide rails 9 and 10 in endless state are disposed parallel with each other along a circulating route J. Chain plates are disposed so as to move along the circulating route J, and a plurality of net panels 6 are installed at specified intervals. A guide shaft is fitted to the upper parts of a pair of side plates on both sides of the net panels, and guide rollers 18 are installed on the guide shaft and inserted into a guide roller guide rail. In the same manner, a spindle is fitted to the lower parts of the side plates, and chain rollers 20 are installed on a lower shaft and inserted into a chain roller guide rail 9. The two lines of the guide rollers 9 and 10 bring the net panels into a closed state by reducing the distance therebetween in an area A on the upstream side of the circulating route J, and bring the net panels into an open state by increasing the distance in an area B on the downstream side.

摘要： PROBLEM TO BE SOLVED: To prevent fitting holes from being made oblong ones due to overload of a basket or garbage applied to fitting bolts, to prolong the life of the basket, and also to prevent the generation of vibration or noise by reinforcing fitting hole parts perforated in right and left end plates of the basket by boss parts. SOLUTION: An endless carrier chain spread between upper and lower sprockets is rotated, and a basket attached to the carrier chain is rotated. After, with the rotation, garbage is scooped up from an intake path and is filtered out to catch it, it is made to fall into a garbage trough to collect it. In this case, on the side of at least one face of a fitting hole part 12 pierced in an end plate 10 of the basket, a reinforcing boss part 17 is provided projectingly by welding or the like. A bolt 14 is inserted into fitting holes 16a, 16b of a pair of link plates 11a, 11b opposite to each other forming the carrier chain, a collar 13 for keeping an interval, and a fitting hole part 12 to tighten it by a nut 15.

摘要： PROBLEM TO BE SOLVED: To enable an effective automatic treatment to be performed in a small sized sewage treating facility, and to reduce the economical cost by discharge sludge integrated into one body with filter medium to the outside by opening the bottom of a case or rotating the case 180 degrees. SOLUTION: The sludge 11 is charged into the case 3 in which filter medium is laid 4 via a sludge feed device 2, then a movable suction 53 with permitted vertical movement is abutted on the bottom of the case 3 from a vacuum suction means 5, thus a dehydration process for reducing the inner water by an appropriate amount is performed. Later, the case 3 successively moves via a chain belt 12 and a drying process is performed in accordance with the movement. Here, microwaves generated with a microwave heating device 6 are irradiated to the sludge 11 in the case 3. After completion of the drying process, the case 3 fulfilled with the sludge 11 is rotated about 180 degree in the up and down direction, then the considerably dried sludge 11 falls down together with the filter medium 4, and for example are collected in a collection case 9.

摘要： PURPOSE:To improve the air permeability of gypsum cake layer on evacuation to increase the dehydration performance and to increase the dehydration performance to shorten the filtration time by destroying an impurity fine particle film layer on the gypsum cake layer before and/or after the supply of washing water for washing the gypsum the cake layer. CONSTITUTION:In a vacuum dehydrator for a gypsum slurry, after washing out chlorine ions contained in the gypsum slurry by a washing water feeding device 9, a dandy roll 2 for destroying an impurity fine particle film layer on the surface of gypsum cake layer 3 is newly installed. The dandy roll 2 is a drum having a lot of projections on the external surface, and is rotated, causing the impurity fine particle film layer to be destroyed by the projections. Therefore, a dense film of the fine particles is eliminated to improve the air permeability of the gypsum cake layer 3 on evacuation and by improving the air permeability, the dehydration performance is improved.

摘要： PURPOSE:To provide a method and a device capable of dehydrating sand in two-stage times and of being easily maintained. CONSTITUTION:The dewatering bottom part of a dehydration basket 2 is formed by stretching a dewatering network 25 and a filter cloth 26 on the opened bottom face. A plurality of dehydration baskets 2 are stuck to an endless chain at the proper intervals by connecting the dewatering bottom part sides to the chain. A raw liquid supply tank 4 is provided which supplies raw liquid containing sand to the hydration baskets 2. A detection switch 55 for detecting deposition of sand in the dehydration baskets 2 is provided and the endless chain is intermittently travelled. An air cylinder 61 closes the upper face of the aperture of the dehydration basket by a cover 64 in the next transfer position. An air force-feeding device force-feeds compressed air into the dehydration basket 2 by arranging an air nozzle 71 in the cover 64. A sand receiving tank 8 is provided in the reverse part of the endless chain. Raw liquid containing sand is supplied to the dehydration basket and naturally dewatered. The aperture of the upper face of the dehydration basket is closed and compressed air is force-fed into the dehydration basket to forcedly dewater sand. Dewatered sand falls from the dehydration basket in the reverse part and is discharged.
