Description

Technical Field

[0001] The invention relates to the technical field of water tank sewage discharge, in particular to a water tank sewage discharge system for high-density grass carp breeding. Background Art

[0002] In the process of grass carp farming, grass carp are usually farmed in concrete tanks, and the feces and leftover baits accumulated in the high-density farming process of grass carp are accumulated at the bottom of the tank, which needs to be processed in time to maintain water quality, and a sludge pump is used to connect the pipes for cleaning.

[0003] The existing grass carp high-density breeding tank sewage system, during use, has a sieve plate at the bottom of the sewage suction pipe, and the dirt is refined through the mesh holes of the sieve plate. However, some dirt has strong adhesion, so that the dirt blocks the mesh holes of the sieve plate, reducing the suction effect of the dirt, reducing the dirt cleaning efficiency, and increasing the output power of the sludge pump, consuming electricity, and increasing the energy consumption of the sludge pump. It is not energy-saving and may even cause the sludge pump to run idle, thereby damaging the sludge pump, resulting in poor dirt adsorption effect and poor use effect.

[0004] In addition, during use, the existing grass carp high-density breeding tank sewage system has a certain thickness of dirt. After the sewage suction pipe falls to the top surface of the dirt, the bottom surface of the sewage suction pipe contacts the dirt, and the suction area is small. Moreover, since the dirt is relatively solid after sedimentation, the dirt forms a whole, and the dirt suction effect is poor. The dirt cannot be effectively sucked out quickly, and the friction between the dirt needs to be overcome. The dirt suction takes a long time and the use effect is not good.

[0005] On the other hand, in the existing grass carp high-density breeding tank sewage discharge system, during use, after the dirt at the bottom of the suction point is sucked out, the suction pipe is in contact with the concrete tank due to gravity, causing a certain degree of blockage on the bottom of the suction pipe, and the suction effect becomes poor. When the suction pipe is dragged to move, the bottom of the suction pipe is prone to tipping over, and the direction of the suction port of the suction pipe changes, which reduces the dirt suction effect and poor movement effect. Summary of the invention

[0006] The present invention provides a sewage discharge system for a high-density grass carp breeding tank, which has the advantages of avoiding clogging of a screen plate, improving the dirt suction effect, and facilitating the movement of a sewage suction pipe, thereby solving the problems mentioned in the above background technology.

[0008] Preferably, the upper limit sleeve is located above the sieve plate, and the lower limit sleeve is located below the sieve plate.

[0012] Preferably, a weight sleeve is fixedly sleeved on the outer surface of the vertical pole.

[0013] Preferably, a connecting plate is fixedly connected to the side of the sludge pump, and a buoy is fixedly connected to the side of the connecting plate.

[0014] Preferably, a conical head is fixedly connected to the lower end of the movable sleeve, and the lower end of the conical head is located below the caster.

[0015] The present invention has the following beneficial effects:

[0016] 1. The sewage discharge system of the grass carp high-density breeding tank is realized by movably adjusting the rotating shaft on the bottom surface of the sieve plate, and fixing the upper limit sleeve and the lower limit sleeve respectively located above and below the sieve plate on the outer surface of the rotating shaft, so that the rotating shaft can rotate freely in the sieve plate, and the circular plate on the top surface of the rotating shaft is used to connect the blades, so that the huge suction force in the sewage suction pipe drives the blades to rotate, thereby realizing the rotation of the rotating shaft, and through the cleaning rod connected to the side of the lower limit sleeve, the cleaning rod is always rotated on the bottom surface of the sieve plate, and the dirt adhered to the bottom surface of the sieve plate is scraped off, so as to avoid the sieve holes of the sieve plate from being blocked, thereby ensuring the suction effect, avoiding the sludge pump from idling, avoiding the sludge pump from abnormal energy consumption, and achieving good use effect.

[0017] 2.

When the suction pipe is moved again, the casters are used to achieve stable movement of the suction pipe, avoid tipping over of the suction pipe, and improve suction stability.

[0029] The upper limit sleeve 11 is located above the sieve plate 7, and the lower limit sleeve 12 is located below the sieve plate 7. The upper limit sleeve 11 and the lower limit sleeve 12 are used to ensure that the shaft 8 does not slide up and down and ensure that the shaft 8 only performs rotational motion.

[0030] The top surface of the movable sleeve 15 is provided with an inner groove 16, and the side surface of the inner groove 16 is provided with a clamping groove 17. The clamping groove 17 and the clamping rod 14 on the outer surface of the rotating shaft 8 are movably clamped, so that the movable sleeve 15 rotates with the rotating shaft 8 and has an upward movement effect.

[0031] Among them, the outer surface of the rotating shaft 8 is movably connected to the inner groove 16, the outer surface of the rotating shaft 8 is fixedly connected with the clamping rod 14, the outer surface of the clamping rod 14 is movably connected to the clamping groove 17, and a spring 24 is fixedly connected between the bottom surface of the inner groove 16 and the bottom surface of the rotating shaft 8. Utilizing the elasticity of the spring 24, the movable sleeve 15 can move up and down along the rotating shaft 8, ensuring the effect of crushing dirt while having the effect of moving upward to compress the spring 24 after contacting the bottom surface of the sink.

[0032] Among them, the side of the caster 6 is fixedly connected to a support plate 20, the inner side of the support plate 20 is fixedly connected to a fixing rod 21, and the inner end of the fixing rod 21 is fixedly connected to a scraper 22. The scraper 22 is used to clean the rotating wheel of the caster 6 to prevent a large amount of dirt from adhering to the rotating wheel.

[0033] The outer surface of the vertical pole 5 is fixedly sleeved with a weight sleeve 23, and the weight sleeve 23 is used to increase the gravity of the vertical pole 5, so that the caster 6 has downward stability and avoids tipping.

[0034] A connecting plate 25 is fixedly connected to the side of the sludge pump 1, and a buoy 26 is fixedly connected to the side of the connecting plate 25. The buoyancy of the buoy 26 is utilized to float the sludge pump 1 and ensure the stability of the sludge pump 1 on the water surface.

[0035] The lower end of the movable sleeve 15 is fixedly connected with a conical head 18, and the lower end of the conical head 18 is located below the caster 6. The conical head 18 makes it easier for the movable sleeve 15 to be inserted into the dirt, thereby improving the suction effect.

[0036] Working principle: start the sludge pump 1, and the sludge at the bottom of the sewage suction pipe 2 is sucked upward. The blade 10 rotates, and drives the rotating shaft 8 connected to the bottom end of the circular plate 9 to rotate, so that the lower limit sleeve 12 rotates, and then the cleaning rod 13 connected to the side of the lower limit sleeve 12 rotates to scrape the bottom surface of the screen plate 7. As the blade 10 rotates, the rotating shaft 8 drives the movable sleeve 15 that is movably connected to the outside of the rotating shaft 8 to rotate, and makes the breaking rod 19 on the outer surface of the movable sleeve 15 rotate to stir the dirt layer, so that the dirt layers are separated and broken from each other and sucked into the sewage suction pipe 2. When the dirt at the bottom of the sewage suction pipe 2 is sucked out and the bottom of the sink leaks out, the conical head 18 drives the movable sleeve 15 to compress the spring 24, and the movable sleeve 15 moves upward along the rotating shaft 8. The caster 6 contacts the bottom of the sink. As the sewage suction pipe 2 moves, the caster 6 moves along the bottom of the sink.
