Water tank dirt discharge system for grass carp high-density breeding

Abstract

The invention relates to the technical field of water tank dirt discharge, and discloses a water tank dirt discharge system for grass carp high-density breeding. The water tank dirt discharge system involves a sludge pump, wherein the input end of the sludge pump fixedly communicates with a dirt suction pipeline; and the lower end of the dirt suction pipeline is fixedly sleeved with a fixing sleeve, and the outer surface of the fixing sleeve is fixedly sleeved with a mounting plate. According to the water tank dirt discharge system for grass carp high-density breeding, an upper limiting sleeveand a lower limiting sleeve which are located on the upper face and the lower face of a sieve plate respectively fixedly sleeve the outer surface of a rotating shaft so that the rotating shaft can rotate freely in the sieve plate; blades are connected to a circular plate on the top face of the rotating shaft, so that huge suction force in the dirt suction pipeline drives the blades to rotate, andthen the rotating shaft rotates; and cleaning rods are connected to the side face of the lower limiting sleeve, so that the cleaning rods always rotate on the bottom face of the sieve plate and scrape away dirt adhering to the bottom face of the sieve plate, sieve holes of the sieve plate are prevented from being blocked, the suction effect is guaranteed, idling of the sludge pump is avoided, abnormal energy consumption of the sludge pump is avoided, and the using effect is good.

Description

Technical field [0001] The invention relates to the technical field of water tank sewage discharge, in particular to a grass carp high-density breeding tank sewage system. Background technique [0002] In the process of grass carp culture, grass carp is usually cultured in concrete tanks, and the feces and residual bait accumulated in the process of high-density grass carp culture are at the bottom of the tank, which needs to be treated in time to maintain water quality, and a sludge pump connected to the pipeline is used to achieve cleaning. [0003] In the existing grass carp high-density aquaculture tank sewage system, during use, because the bottom of the suction pipe is equipped with a sieve plate, the mesh of the sieve plate can realize the refinement of the dirt. However, part of the dirt has strong adhesion, making Dirt blocks the mesh of the sieve plate, reduces the suction effect of the dirt, reduces the efficiency of dirt cleaning, and increases the output power of the s...

AI Technical Summary

Problems solved by technology

[0003] During the use of the existing grass carp high-density breeding tank sewage system, since the bottom of the sewage suction pipe is equipped with a sieve plate, the dirt is refined through the mesh of the sieve plate, but some dirt has strong adhesion, making Dirt blocks the mesh of the sieve plate, reduces the suction effect of the dirt, reduces the dirt cleaning efficiency, and increases the output power of the sludge pump, consumes electric energy, increases the energy consumption of the sludge pump, does not have energy saving, and even causes the sludge pump to Idling, and then damage the sludge pump, the dirt adsorption effect is poor, and the use effect is not good

[0004] In addition, due to the fact that the dirt has a certain thickness in the existing grass carp high-density aquaculture tank sewage system, the suction area is small after the sewage suction pipe falls to the top surface of the dirt, and the bottom surface of the sewage suction pipe is in contact with the dirt. After the dirt is deposited, it is relatively solid, and the dirt is integrated. The suction effect of the dirt is poor, and the dirt cannot be effectively sucked quickly. It needs to overcome the friction between the dirt. The dirt suction takes a long time and the use effect is not good.

[0005] On the other hand, during the use of the existing sewage system for high-density breeding tanks of grass carp, when the dirt at the bottom of the suction part is sucked, the sewage suction pipe is in contact with the concrete tank due to gravity, and the bottom surface of the suction pipe is blocked to a certain extent , the suction effect becomes worse, and when the suction pipe is dragged to move, the bottom of the suction pipe is prone to rollover, and the suction port of the sewage suction pipe changes direction, which reduces the dirt suction effect and poor moving effect
