Abstract

The present invention can separate and remove sludge by centrifuging the red tide and green algae of marine aquaculture farms and reservoirs, and separate sludge contained in the wastewater of concentrated plant and factory to obtain clean water. It relates to a cleaning device for centrifugation.

In the conventional liquid centrifuge, it is configured to perform centrifugal action of rotation while flowing water into the separation pipe along the inlet hole drilled through the inner wall of the water rotating tube by using the flow rate of water and flowing into the upper wall of the separation pipe. This is because the rotational force is weak and the rotation is slow due to the centrifugal rotation due to the flow rate, so that the heavy sludge is separated from the large sludge but the light weight from the small mesh is not separated. The present invention constitutes a pressure lever with a diaphragm in the body of the centrifuge to allow the inflow of indefinite water from the motor pump, and the diameter of the pressure lever connected in communication with the large centrifuge tube vertically installed in the body The small clean water separation pipe is separated from the upper and lower parts, and the water is rotated by the inclined water when the water pressure is received from the pressure lever. In order to separate the clean water is separated by the clean water separation pipe and the sludge is to be drained into the sludge drain hole drilled in the screw of the lower cap, the present invention can be carried out by a single centrifugal separator alone and It is an invention that can be used by combining a single centrifuge in combination.

Description

Cleaner for centrifuging sludge in indefinite water

The present invention is capable of removing sludge by centrifuging the red algae generated around the marine farms or the green algae of lakes and reservoirs, and also containing sludge contained in unclean wastewater and impurities flowing out of factories and thickeners. The present invention relates to a cleaning device for centrifuging sludge in untreated water to separate the water to obtain the maximum clear water.

Conventionally, a liquid centrifuge for obtaining clean clean water is provided with a cylindrical water tumbler on the upper part of the separation pipe, and an inlet water inlet pipe is installed to flow in the lateral direction of the water tumbler. The water flows through the inner wall of the tank and the inlet water is introduced into the separation pipe through the inlet hole, which is drilled on the upper wall of the separation pipe exposed through the water trough, and the clean water discharged by fixing the clean water discharge pipe on the upper part of the separation pipe. The condensed vortex is installed at the center of the upper part of the separation pipe with a sludge discharge pipe in the lower part of the separation pipe, and the negative water flows into the water flow through separation pipe by the motor pump. In this case, centrifugal force acts by the flow velocity, and conical vortex in the lower part By a centrifugal separated clean water is to be raised to the top and clear water drainage along the discharge pipe. In other words, this is a centrifugal force rotation due to the flow rate, so the rotation is slow in the separation pipe, so the heavy specific gravity (large mesh) sludge is separated, but the mesh is small and the relative specific gravity has not been separated. Therefore, the conventional liquid centrifuge has not been used because of the red tide phenomenon occurring near the marine farm and the green water phenomenon of the lake, reservoir, etc. due to the closed end where the efficiency of centrifugation is very low.

The present invention is to solve such a problem in the prior art, the present invention is to improve the structure so that the centrifugal force due to pressure acts quickly to centrifuged fine sludge (less mesh), that is, containing a specific gravity in water The purpose of this is to separate the sludge from the red tide and the green algae in the sea and reservoir, and to filter the sludge so that the clear water can be used.

In addition, the present invention is equipped with a multi-stage centrifuge and a single centrifuge composed of a plurality of sludge separated from the multi-stage centrifuge is introduced into the sludge tank and the impurities of the sludge tank is separated again while passing through the single centrifuge And dewatered again from the screw dehydrator so that the pure sludge is carried out through the heat tunnel by the belt conveyor. Not only can it be obtained, but it can also filter out large numbers of red tide and green algae phenomena per unit time, so that it is possible to use a clean device with excellent utilization efficiency.

First, impurities such as blades of grass floating in indefinite water are removed by the projection 1 'installed in the powerful screen conveyor apparatus 1. Since the screen conveyor apparatus 1 is formed of a porous belt plate, the indefinite water is filtered out by the porous belt plate, and the blades of grass and the like are caught and removed by the rotating protrusion 1 '. The filtered negative water is sent from the tank 2 to the multi-stage centrifuge 4 by the motor M pump P through the water pipe 3. The clear water filtered by centrifugation in this multi-stage centrifuge (4) is sent to the water tank (5) through the water pipe (3a) and the sludge from the multi-stage centrifuge (4) through the water pipe (3a ') to the motor ( M ') flows into the sludge tank 6 by the pump P'. In addition, the sludge introduced into the sludge tank 6 is introduced into the water tank 5 through the water pipe 3a ″ and the sludge separated from the single centrifuge 4a is transferred to the motor M ″ 'through the water pipe 3b. Is sent to the screw dehydrator 7 by means of a pump P " Clear water from the screw dehydrator (7) is separated and stored in the water tank (5) through the water pipe (3b ') and the sludge from the screw dehydrator (7) is transferred to the belt conveyor (9) in the heater tunnel (8) and dried. It goes out. And the clear water of the water tank (5) is drained to the required place by the motor (Ma) pump (Pa). In the figure, reference numeral 10 denotes an electric control plate. 2 and 3 show a plan view of the multi-stage centrifuge 4 and a side view of a partial cross section, in which the pressure chamber 13 is divided into diaphragms 12, 12 'in the body 11 of the centrifuge. In this case, the indefinite water introduced by the motor M and the pump P is introduced into the pressure chamber 13 and between the lower support plate 14 and the upper plate 12 and 12 'of the body 11. 5 is installed vertically in communication by inserting and connecting the lower portion of the centrifuge tube body 15 and the clean water separator tube 16 shown in cross-section in FIG. 5 with the upper cap 17 and the lower cap 18 with a diaphragm 12 and 12 '.
