The present invention is referred to as dull sediment deposited on the bottom of rivers, lakes, harbors or golf course ponds (often caused by untreated sewage or factory wastewater or industrial wastes). The present invention relates to a sludge collector for effectively inhaling and collecting and a sludge treatment apparatus for treating collected sludge.

Generally, cracks of sediment generated by untreated sewage, factory wastewater, or industrial wastes are deposited on the bottom of rivers, lakes, ports, or ponds. The generation of sludge is on the rise with the development of industry, and the increase of sludge causes environmental pollution and has emerged as a serious social problem. Such sludges are particularly common in ponds without water flow, for example in ponds on golf courses. The presence of sludge in the pond is a source of water pollution, so it must be collected and removed regularly. When sludge is present in the pond about 3 to 5%, the water becomes dirty and water is contaminated by gel sediments mixed with organic and inorganic substances, and even organisms cannot survive. It should be collected and removed regularly.

Conventionally, in order to remove the sludge of a pond, the conventional method of discharging the pond water, collecting the sludge of the bottom, and supplying water again is used. Therefore, the work is cumbersome and inefficient, and the removal of sludge is not only effective, but there is also a problem in its treatment.

The present invention has been made in view of the above problems, and provides a sludge collector for effectively sucking and collecting sludge settled on the bottom of a pond and a sludge treatment apparatus for stable treatment of the collected sludge. There is a main purpose.

Another object of the present invention is to provide a sludge treatment apparatus for a pond that can be reused as a building aggregate by solidifying the collected sludge and simultaneously crushing and discharging the sludge.

Separation means for separating the element treated in the water and sludge, a return tank for receiving the water separated by the separation means and return the received water to the churn tank, and screw conveyor for transporting the sludge separated by the separation means to the outlet Provided is a sludge treatment apparatus for a pond configured to include a.

Preferably, the pipe is vertically connected with respect to the horizontal plane of the cylindrical network, the flexible pipe of the suction source is made to the flange coupled to the pipe, and the suction plate is welded and attached under the interposition of the reinforcement.

More preferably, the sludge treatment apparatus of the present invention has a bridging agent injector for removing a harmful component of the sludge discharged into the discharge port and administering a solidifying agent for solidification, and a shredding unit for finely crushing and discharging the solidified sludge. The sludge kneader is further provided to reuse the collected sludge as building aggregate. In addition, the foreign matter separating means is composed of a rotating cylindrical sieve, and a drive motor for rotationally driving the sieve, the motor and the sieve is connected to the belt to achieve power transmission.

Hereinafter, preferred embodiments of the present invention as described above will be described in more detail with reference to the accompanying drawings. The sludge collector of the present invention consists of a cylindrical network 1 having a thin eye structure. The upper portion of the cylindrical reticular body 1 is connected to and installed with a suction source (not shown, but usually using a vacuum pump, etc.) for imparting a suction force, the lower portion using a vacuum force Inhalation prevention plate (3) is attached to prevent inhalation of soil on the floor. The pipe 2 is connected perpendicularly and upwardly to its intermediate point with respect to the horizontal plane of the cylindrical network 1. The sludge at the bottom of the pond can be effectively collected by such a straight connection in the vertical direction of the pipe 2. In addition, the other end of the pipe (2) is flanged to the flexible pipe (4) connected to the suction source. Meanwhile, as shown in FIG. 2, the suction preventing plate 3 is attached to the lower portion of the cylindrical network 1 by welding, and is provided on both sides via rod-shaped reinforcing members 5 and 5 ′. The welding force can also be increased by welding. It is not necessary to limit the size of the cylindrical reticular body (1) in the structure of such a collector, but it is suitable if the size of the human being does not follow the movement because it is a work method to artificially put into the pond. Further, the grid size of the cylindrical network 1 may be such that the sludge flows freely, but the size of the bottom of a relatively large component of the floor is not caught and sucked. In addition, the size of the suction preventing plate 3 may be equal to the horizontal length of the cylindrical network 1, and the vertical length may be equal to or slightly larger than the diameter of the cylindrical network 1.

In FIG. 1, 6 shows a solidified layer forming the bottom of the pond, 7 shows a sludge layer deposited on the solidified layer 6, 8 shows water, and the collector shows a solidified layer of the pond ( 6) will be located above. In this state, when the suction source, for example, the vacuum pump is operated, a strong suction force is generated in the cylindrical reticular body 1 while sucking and collecting sludge from the bottom. At this time, the water is also sucked as in the sludge, the raw water sucked in this way is collected and treated in the treatment tank of the sludge treatment apparatus described later. In addition, since the suction preventing plate 3 attached to the lower part of the cylindrical network 1 presses the solidified layer 6 at the bottom in the process of sucking the sludge, only the sludge is effectively sucked without the soil of the solidified layer 6 being sucked. Is inhaled.

Here, the foreign matter separating means 11 is composed of a rotating cylindrical sieve 11a and a driving motor (not shown) for rotating the sieve 11a. The sieve 11a and the driving motor are belts. Is connected to achieve power transmission. In addition, the end of the sieve (11a) is connected to the foreign matter discharge port 20 for discharging the foreign matter to be separated, the lower portion is provided with an element supply tank 12 for receiving the raw water flowing out of the sieve (11a), The raw water supply tank 12 and the processing tank 14 are connected by the raw water supply pipe 21 to supply raw water from which foreign matters are removed to the processing tank 14. In addition, the raw water inlet pipe 22 to which the flexible pipe 4 of the sludge collector is connected to the front end of the sieve 11a. In the drawings, reference numeral 23 denotes a raw water return pipe, 24 denotes a workbench, and 25 denotes a generator.

In other words, the present invention sedimented sludge in the treatment tank 14, the raw water collected by the sludge collector, and after separating it into water and sludge again in the separating means 16, the purified water is a pond ( Water with sludge is sent back through the return tank to the treatment tank), and only the separated sludge is transferred to the screw conveyor 19 to be discharged, and the sludge from the pond can be collected and treated continuously. .

On the other hand, the present invention in the illustrative example is to remove the harmful components of the sludge discharged to the discharge port 18, and solids injector 26 for administering a solid agent for solidifying, and crushed for crushing the discharged sludge finely The sludge kneader 27 which has the part 27a is further provided, and it is comprised so that the collected sludge may be reused as a construction aggregate. In other words, the present invention is configured to be used to collect and process the sludge of the pond more efficiently and at the same time to solidify it as a construction aggregate, look at the sludge collection and treatment process of the present invention in more detail as follows. .

The sludge collector, which is located in the pond and collects the sludge of the bottom, has its flexible pipe 4 connected to the raw water inlet pipe 22 of the foreign matter separating means 11 to form an initial state of work. When the device is started in such a state, the suction source, for example, the vacuum pump is driven, and the vacuum force generated accordingly is transmitted to the cylindrical reticular body 1 of the collector, so that a strong suction force is generated and the sludge at the bottom of the pond is generated. Inhaled raw water is contained. The raw water sucked in this way is introduced into the foreign matter separating means 11 through the flexible pipe 4 and the raw water inlet pipe 22. Here, foreign substances such as vinyl contained in the raw water are separated and the foreign substances are discharged from the foreign substance outlet. The raw water is discharged through, and the foreign matter is separated into the raw water supply tank 12 at the bottom. The raw water of this raw water supply tank 12 is supplied to the processing tank 14 through the raw water supply pipe 21. The treatment tank 14 receives raw water from the raw water supply tank 12 and sediments the sludge in the raw water. After stirring by (13), the sludge settles while passing through the 1st settling tank 14b and the 2nd settling tank 14c sequentially. As such, the raw water passing through the treatment tank 14 enters the separation means 16 again, where the raw water is separated into water and sludge. The separated water is returned to the treatment tank 14 again for filtration of the sludge via the return tank 17, and the sludge is transferred to the outlet 18 by the screw conveyor 19. On the other hand, in the discharge port 18, a solid agent injector 26 is installed and solidified by adding a solid agent to the sludge to be transported. At this time, the harmful components in the sludge are also removed to become a harmless solid. The sludge solids thus obtained are finely crushed, dried and discharged through the sludge kneader 27 having the crushed portion 27a. The sludge solid discharged in this way can be used for this purpose in the form of a building aggregate. In other words, the waste sediment in the pond can be collected and treated, and used as aggregate for construction.

As described in detail above, according to the present invention, the sludge in the pond can be effectively sucked and collected. That is, it is possible to suck and collect only the sludge on the upper part without inhaling the soil of the solidified layer, which is the bottom layer, and to carry out the work effectively such as the continuous collection of the sludge and the stable treatment of the collected sludge. There are several advantages, such as the ability to reuse sludge for construction aggregates.
