Description
Technical Field
[0001] This utility model relates to the field of wastewater purification technology, specifically a wastewater purification device for high-density fishponds. Background Technology
[0002] Artificially farmed freshwater fish are usually raised in fishponds, which are places for catching or raising fish, specifically referring to the enclosures or nets used to enclose the fish. Fishponds can be natural ponds or artificial ones. In artificial fishponds, the water is sometimes stagnant. Raising freshwater fish in stagnant water makes it difficult for the fish to survive, and feeding them also pollutes the freshwater, which, if left untreated, becomes wastewater and affects the quality of fish farming.
[0003] However, existing wastewater treatment devices for fish ponds still have some problems in actual use. Wastewater treatment devices generally suck in wastewater, filter it through a filtration device, and then discharge it. However, prolonged use of the filtration device can cause the internal filter screen to become clogged, and the dirt adsorbed on the surface of the filter screen is also very troublesome to deal with. Therefore, we propose a wastewater purification device for high-density fish ponds to solve the above problems. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a wastewater purification device for high-density fishponds, solving the problems mentioned in the background section.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a sewage purification device for high-density fish ponds, including a device shell, a drain pipe fixedly connected to one side of the bottom of the device shell, a filter screen bucket fixedly installed inside the device shell, a sewage pipe connected to the bottom of the filter screen bucket, and a sewage pump and a collection box connected in sequence to one end of the sewage pipe.
[0006] The equipment casing is also equipped with a sludge extraction structure and a cleaning structure;
[0007] The sludge suction structure includes a connecting pipe, one end of which is connected to the inside of the equipment housing, and the other end of which is fixedly connected to a sludge suction pump. The bottom end of the sludge suction pump is sequentially connected to a telescopic pipe and a sludge suction head. An isolation mesh cover is fixedly installed on the outer wall of the sludge suction head at the bottom end of the telescopic pipe. A magnetic component is fixedly installed on the upper surface of the isolation mesh cover. A receiving pipe is fixedly installed on the outer wall of the bottom end of the sludge suction pump, and an electromagnet is fixedly installed at the bottom end of the receiving pipe.
[0008] The cleaning structure includes a hydraulic cylinder, a fixed pipe, and a water outlet pipe. The side wall of the water outlet pipe has several water outlet holes. One end of the water outlet pipe is connected to a circulation pipe through a flexible hose body. One end of the circulation pipe is connected to a circulation pump and a extraction pipe in sequence.
[0009] Furthermore, the suction head and the isolation mesh cover are porous metal meshes, and the first magnetic component is a ring-shaped magnetic suction component. The magnetic pole direction of the first magnetic component is opposite to the magnetic pole direction generated when the electromagnet is energized, so as to superimpose the magnetic field strength.
[0010] Furthermore, the telescopic tube is a rubber corrugated hose, the receiving tube is a rigid plastic sleeve with a guide groove on the inner wall, and the outer wall of the sewage pump is fixedly installed on the outer wall of the equipment casing.
[0011] Furthermore, the hydraulic cylinder is fixed to the top of the equipment housing, and the output end of the hydraulic cylinder is rotatably connected to the fixed pipe to drive the water outlet pipe to reciprocate along the inner wall of the filter screen bucket. The water outlet hole of the water outlet pipe is an inclined nozzle structure.
[0012] Furthermore, the hose body is a pressure-resistant rubber hose, used to achieve a flexible connection between the outlet pipe and the circulation pipe.
[0013] Furthermore, one end of the extraction tube extends into the interior of the equipment housing, and the other end of the extraction tube is connected to the input end of the circulation pump for extracting water from the equipment housing.
[0014] The beneficial effects of this utility model are:
[0015] 1. This wastewater purification device for high-density fishponds uses a hydraulic cylinder to drive the outlet pipe to move back and forth along the inner wall of the filter screen. The inclined nozzles on its side wall spray high-pressure water to thoroughly clean the filter screen surface with 360° no dead angles, completely removing adsorbed viscous dirt (such as fish feces and uneaten food mucus). The circulation pump draws the purified water from the equipment through the extraction pipe and delivers it to the outlet pipe through the circulation pipe and hose body, forming a "extraction-rinse-recirculation" circulation system. There is no need to introduce additional clean water, which saves water resources and ensures that the filter screen always maintains a high permeability, avoiding the decrease in purification efficiency caused by clogging in traditional static filtration.
[0016] 2. This wastewater purification device for high-density fishponds uses a sludge pump that, through a telescopic pipe and a sludge suction head, can flexibly extract suspended solids from the wastewater. The isolation mesh can prevent large particles from entering the suction head, thus avoiding blockage. On the other hand, when the electromagnet is de-energized, the magnetic field disappears, the magnetic component separates from the electromagnet, and the isolation mesh and the suction head, due to their own gravity, suck the wastewater into the pond, significantly improving the sludge extraction effect.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0026] Please see Figures 1-6 A wastewater purification device for high-density fishponds includes an outer casing 1, a drain pipe 2 fixedly connected to one side of the bottom of the outer casing 1, a filter hopper 3 fixedly installed inside the outer casing 1, a sewage pipe 4 connected to the bottom of the filter hopper 3, and a sewage pump 5 and a collection box 6 connected to one end of the sewage pipe 4 in sequence. The filter hopper 3 inside the device can directly intercept particulate impurities (such as uneaten food, fish feces, etc.) in the wastewater, preventing them from entering the subsequent treatment process and causing pipe blockage or secondary pollution. The waste intercepted by the filter hopper 3 is directly transported to the collection box 6 through the sewage pipe 4 and the sewage pump 5, realizing centralized treatment of solid waste, eliminating the need for frequent manual cleaning of the filter hopper, and improving the continuity of the purification process.
[0027] The equipment casing 1 is also equipped with a sludge extraction structure 7 and a cleaning structure 8;
[0028] The sludge suction structure 7 includes a connecting pipe 71, one end of which is connected to the inside of the equipment housing 1, and the other end of which is fixedly connected to a sludge suction pump 72. The bottom end of the sludge suction pump 72 is sequentially connected to a telescopic pipe 73 and a sludge suction head 74. An isolation mesh cover 75 is fixedly installed on the outer wall of the sludge suction head 74 at the bottom end of the telescopic pipe 73. A magnetic component 76 is fixedly installed on the upper surface of the isolation mesh cover 75. A receiving pipe 77 is fixedly installed on the outer wall of the bottom end of the sludge suction pump 72. The bottom of the receiving pipe 77... An electromagnet 78 is fixedly installed at one end; a magnetic component 76 is installed on the top of the isolation net cover 75 and is magnetically connected to the electromagnet 78 at the bottom of the receiving tube 77 through a reverse magnetic pole design: when energized, the magnetic component 76 is magnetically connected to the electromagnet 78, which can store the isolation net cover 75 and the sludge suction head 74; when the power is off, the magnetic field disappears, the isolation net cover 75 automatically falls off due to gravity, and the sludge suction head 74 sinks to the bottom of the fishpond, enhancing the extraction of sewage and sediment from the bottom of the pond;
[0029] The cleaning structure 8 includes a hydraulic cylinder 81, a fixed pipe 82 and a water outlet pipe 83. The side wall of the water outlet pipe 83 has several water outlet holes 84. One end of the water outlet pipe 83 is connected to a circulation pipe 86 through a hose body 85. One end of the circulation pipe 86 is connected to a circulation pump 87 and an extraction pipe 88 in sequence.
[0030] Reference Figure 3 , Figure 5 , Figure 6 As shown, the suction head 74 and the isolation mesh cover 75 are porous metal meshes, and the magnetic component 76 is a ring-shaped magnetic suction component. The magnetic pole direction of the magnetic component 76 is opposite to the magnetic pole direction generated when the electromagnet 78 is energized, so as to superimpose the magnetic field strength.
[0031] Reference Figure 3 As shown, the telescopic tube 73 is a rubber corrugated hose, the storage tube 77 is a rigid plastic sleeve, and the inner wall is provided with a guide groove. The outer wall of the sewage pump 72 is fixedly installed on the outer wall of the equipment housing 1.
[0032] In this embodiment, the sludge pump 72 drives the sludge suction head 74 to penetrate into different areas of the sewage through the telescopic pipe 73, which can flexibly extract suspended solids and adapt to the uneven distribution of sewage in high-density fish ponds; the isolation net cover 75 (porous metal mesh) can prevent large particles from entering the sludge suction head 74 and avoid pipe blockage; the magnetic component 76 (ring magnetic suction component) and the electromagnet 78 are designed with opposite magnetic poles. After the power is cut off, the magnetic field disappears and the isolation net cover 75 automatically falls off due to gravity, which makes it easy for the isolation net cover 75 and the sludge suction head 74 to automatically enter the pond, thus significantly improving the sludge suction effect.
[0033] Reference Figures 2-4As shown, the hydraulic cylinder 81 is fixed to the top of the equipment housing 1. The output end of the hydraulic cylinder 81 is rotatably connected to the fixed pipe 82, which is used to drive the water outlet pipe 83 to move back and forth along the inner wall of the filter screen hopper 3. The water outlet hole 84 of the water outlet pipe 83 is an inclined nozzle structure.
[0034] In this embodiment, the hydraulic cylinder 81 drives the water outlet pipe 83 to move back and forth along the inner wall of the filter screen hopper 3. The inclined nozzles on its side wall spray high-pressure water to flush the filter screen surface 360° without dead angles, thoroughly removing the adsorbed viscous dirt (such as fish feces and uneaten food mucus). The circulation pump 87 draws the purified water from the equipment through the extraction pipe 88, and delivers it to the water outlet pipe 83 through the circulation pipe 86 and the hose body 85, forming a "extraction-flushing-return" circulation system. There is no need to introduce additional clean water, which saves water resources and ensures that the filter screen always maintains a high permeability, avoiding the decrease in purification efficiency caused by clogging in traditional static filtration.
[0035] Reference Figure 2 As shown, the hose body 85 is a pressure-resistant rubber hose, used to achieve a flexible connection between the water outlet pipe 83 and the circulation pipe 86.
[0036] Reference Figures 2-4 As shown, one end of the extraction pipe 88 extends into the interior of the equipment housing 1, and the other end of the extraction pipe 88 is connected to the input end of the circulation pump 87 for extracting water from the equipment housing 1.
[0037] In this embodiment, in the cleaning structure 8, the hydraulic cylinder 81 drives the water outlet pipe 83 to reciprocate along the inner wall of the filter screen hopper 3. At the same time, the inclined nozzle on the water outlet pipe 83 sprays water to strongly flush the surface of the filter screen, removing the dirt adsorbed on the filter screen. The circulation pump 87 draws water from the equipment and recycles it. While realizing automatic cleaning of the filter screen, it also reduces the waste of water resources and ensures that the filter screen always maintains a high filtration efficiency.
[0038] In use, magnetic component 76 is installed on top of the isolation net cover 75 and magnetically connected to the electromagnet 78 at the bottom of the receiving tube 77 through a reverse magnetic pole design. When energized, magnetic component 76 and electromagnet 78 are magnetically connected, allowing the isolation net cover 75 and the suction head 74 to be stored. When the power is off, the magnetic field disappears, and the isolation net cover 75 automatically falls off due to gravity, causing the suction head 74 to sink to the bottom of the fishpond, enhancing the extraction of sewage and sediment from the bottom of the pond. The sewage pump 72 is connected to the inside of the equipment casing 1 through the connecting pipe 71. After starting, it extracts sewage through the telescopic pipe 73 and the suction head 74 and transports it to the filter hopper 3 inside the equipment casing 1. The sewage undergoes physical filtration through the filter hopper 3, trapping large particulate solid pollutants such as fish feces and uneaten food. 3 is connected to the sewage pipe 4 below. The intercepted dirt settles to the bottom under gravity and is transported to the collection box 6 by the sewage pump 5, realizing the centralized collection and treatment of solid waste and reducing the frequency of manual cleaning. The filtered sewage flows downward through the filter screen 3 and finally flows to the bottom of the equipment shell 1. Then, the circulation pump 87 draws the purified water from the equipment shell 1 through the extraction pipe 88 and transports it to the outlet pipe 83 through the circulation pipe 86 and the hose body 85. At the same time, the hydraulic cylinder 81 drives the outlet pipe 83 to move back and forth along the inner wall of the filter screen 3. The inclined nozzle-shaped water outlet hole 84 on the side wall of the outlet pipe 83 sprays high-pressure water into the inner wall of the filter screen 3. The water flow impact force peels off the dirt on the filter screen, realizing 360° no dead angle flushing of the filter screen surface and thoroughly removing stubborn attachments.
[0039] The wastewater generated during flushing carries the detached dirt back to the top of the filter hopper 3, where it is filtered again by the filter screen, forming a closed-loop system of "extraction-flushing-recirculation-re-filtration". No additional clean water is required, saving water resources while maintaining the high permeability of the filter screen.
