摘要： PURPOSE:To reduce the size of an apparatus and to enhance a flocculating effect in an agglutination vessel and the dehydrating effect of a muddy water separator by sending muddy waste water to the agglutination vessel under pressure, continuously separating flocks formed in the muddy waste water, sending the waste water flowing out of the vessel to the muddy water separator under pressure and removing mud in the waste water. CONSTITUTION:A polymer flocculant is added to raw water and this raw water is allowed to flow into a vertical multistage flocculation reaction vessel 25 through a feed path 4. A flocculant is successively put in the raw water in stirring vessels 27a-27c and the raw water passes through perforated plates 26a-26c under stirring with stirring blades 30a-30d. During this passing, an agglutination proceeds in the raw water and flocks are formed in the raw water. Since the raw water is prevented from flowing rapidly, the agglutination can be allowed to proceed satisfactorily. The flocks and the treated water are transferred to a muddy water separator 20 and subjected to solid-liq. separation. Since all the stage are carried out as integrated work through hermetically sealed feeding mechanisms, the raw water can be continuously treated.

摘要： PURPOSE:To reduce a water area and to provide the small-sized thickener by adding a fluidized filter layer which can remove small flocks and can be regenerated by washing to the thickener. CONSTITUTION:This thickener includes a flocculation reaction vessel 10 which flocculates suspended materials by mixing a flocculating agent into waste water contg. the suspended materials and stirring the waste water and a settling and separating vessel 20 which settles the formed flocs and separates the flocs from the waste water. Filter media 30 which float by covering the waste water surface in the vessel and a filter medium washing and circulating device 31 which takes the filter media out of the water surface, washes the media and returns the media onto the water surface are disposed within this settling and separating vessel 20. The small flocs ascending without being completely settled in the settling and separating vessel 20 of the thickener are removed by the filter media 30 and, therefore, the water area part for setting the small flocks which is heretofore required for the conventional thickeners is reduced.

摘要： PURPOSE:To cast concrete having good quality by suppressing a rise in the temp. of concrete due to heat of hydration, by supplying aggregate before the kneading of concrete to the continuous moving body provided in a vacuum tank in predetermined moisture content and removing evaporation heat to lower the temp. of the aggregate. CONSTITUTION:Aggregate S such as fine aggregate, coarse aggregate or a mixture thereof having about 15% of surface moisture supplied to a hopper 1 falls on the belts 4 of belt conveyors synchronously driven of respective stages through a vacuum valve 2 on a supply side. When the aggregate S is successively supplied so that the supply amount thereof does not exceed the skirts 6 attached on both sides of the belts 4, the aggregate S becomes the same thickness up to the belt 4 of the lowermost stage over the respective stages. The supply of the aggregate S is stopped and a vacuum valve 8 is opened to drive a vacuum pump 14. The surface water of the aggregate S is evaporated and the temp. of the aggregate is lowered to temp. 3-4 deg.C higher than the surface temp. of the cooler 10 in a cold trap 9. The cooled aggregate S can be discharged while the total amount thereof is cooled by bringing a vacuum tank 3 to atmospheric pressure by opening a vacuum breaking valve 16 and opening a vacuum valve 7 on a discharge side to drive the drive pulleys 5 of the respective stages.

摘要： PURPOSE:To facilitate handling by making uniform the properties of earth and sand such as viscosity when excavated earth and sand is to be carried away. CONSTITUTION:Earth and sand A is put fully in a drafty frame 3 to be formed in a lump B having a certain shape and size, and the lump B is put in a decompression chamber 2 while held in the frame 3. By decompression in the chamber 2, the surface of the lump B is frozen by the water contained in the earth and sand itself. The frame 3 is removed from the earth/sand lump C whose surface is hardened, and this lump C is carried away by a transport device such as a transport pipe using air pressure. Thus the earth and soil from excavation can be embodied into uniform shapes having uniform properties, which facilitates handling.

摘要： PURPOSE:To contrive automation in opening and closing of an airtight lid and complete closing of the same, by a method wherein a hydraulic transmission device performing contacting or separation of an airtight lid to or from opening edge parts of a loading port and overflow in a parallel state and a hydraulic injection device on a contacting side of a link device with the opening edge part and airtight lid are provided on the title device. CONSTITUTION:A loading port 3 is fully opened by an actuation of an air cylinder 17 for an up-and-down motion and a swirling air cylinder 20 without rubbing an O ring of an upper lid 6 with an opening edge part 6a and the loading port is closed by loading aggregate. Since a cylinder rod 20b actuates and injects air under a state when the upper lid 6 is lifted up, the aggregate which is stuck to and left behind on the loading port and upper lid 6 is eliminated. Since a bottom lid 7 is separated from an overflow 4 in a parallel state with contraction and a backward movement of cylinder rods 41b, 42b, the overflow 4 is fully opened without rubbing an O ring of an opening edge part 4a, the aggregate is discharged and then the overflow 4 is closed completely. Then since the air is injected through discharge nozzles 50, 48 when the bottom lid 7 is shunted through the overflow 4, the aggregate stuck to a contacting surface side 7a of the bottom lid 7 and the opening edge part 4a is blown off and eliminated.

摘要： PURPOSE:To dispense with a scaffold of full height and facilitate execution even on the foundation of inclined ground by loading a main pillar on the concrete after placing, contracting jacks so as to pull up a formwork applying the reaction on the main pillar, and extending the jacks so as to push up the main pillar applying the reaction on the formwork. CONSTITUTION:A main pillar 1 is loaded on the upper face of hardened concrete 4. Next jacks 3 are contracted so as to pull up a formwork 2 through a suspended girder 21 applying the reaction on the main pillar 1. The lower end part of a formwork 2 is fixed to the concrete 4. This work of pulling up and fixing is executed from a scaffold 5 connected to the suspended girder 21. Next the jacks 3 are extended so as to push up the lower end of the main pillar 1 up to a little higher position than the surface of concrete succeedingly being placed applying the reaction on the formwork 2. Next, concrete is placed in the formwork 2. By repeating the above-mentioned operations, a scaffold from the foundation to the upper end is unnecessary, and the execution is facilitated even if the foundation ground is uneven or inclined.

摘要： PURPOSE:To obtain a simple miniaturized filter apparatus suitable for the spot and capable of again using a filter material by washing by a method wherein a filter tank is divided into two sections when the filter material possible to take up and rewind is passed through the filter tank to be consumed to wash off the solid bonded to the filter material to remove the same downwardly from the filter tank. CONSTITUTION:Turbid water is pressurized by a pump to be introduced into a filter tank 3. A roll-shaped filter material 4 is provided in the filter tank 3 to vertically pierce through the filter tank 3 and taken up by a winder 5. Since the turbid water is pressurized to a certain degree, it passes even through a fine mesh filter material and, when the whole of the roll-shaped filter material 4 is taken up, the filter tank 3 is divided into two sections by an air cylinder 7, and the roll-shaped filter material 4 is unwound by an unwinding machine 6. At this time, water is discharged from an ejector 12 to wash off the solid/ earth and sand on the surface of the filter material and the filter material again restores filtering power.
