Description

Technical Field

[0001] This utility model relates to the field of aquaculture microfiltration technology, and in particular to an aquaculture microfiltration machine. Background Technology

[0002] Aquaculture microfiltration machines are mechanical devices commonly used for solid-liquid separation in aquaculture water. They primarily use rotating microfiltration screens to efficiently trap and separate suspended particles, uneaten feed, and fish excrement from the water, thereby achieving water purification and recycling. This equipment is typically installed at the upstream end of the aquaculture pond or circulating water treatment system. Water pressure or mechanical drive forces water through the microfiltration screen; larger particles are blocked and automatically discharged. The purified water is then returned to the aquaculture pond, maintaining clean and stable water quality while improving water utilization and aquaculture efficiency.

[0003] In existing technologies, impurities adhering to the surface of the filter screen after filtration are difficult to effectively treat. Impurities tend to accumulate on the surface of the screen for a long time or even become embedded in the mesh. This not only increases the resistance to water flow during subsequent filtration and reduces filtration efficiency, but may also cause the filtration effect to deteriorate due to impurities clogging the mesh, making it impossible to effectively intercept pollutants in the water and affecting the quality of aquaculture water. Utility Model Content

[0004] Given that the impurities adhering to the surface of the filter screen after the existing filtration process are difficult to effectively treat, and that the impurities tend to accumulate on the surface of the screen or even become embedded in the mesh, this not only increases the resistance to water flow during subsequent filtration and reduces filtration efficiency, but may also cause the filtration effect to deteriorate due to impurities clogging the mesh, thus failing to effectively intercept pollutants in the water and affecting the quality of aquaculture water, this utility model is proposed.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a microfiltration machine for aquaculture, comprising a filtration device, a filtration component, and an anti-clogging structure. The filtration component and the anti-clogging structure are respectively installed inside the filtration device. The anti-clogging structure includes a rack, a multi-stage electric push rod, a suction pump, and a negative pressure box. A mounting frame is fixedly installed on the telescopic end of the multi-stage electric push rod. A gear is mounted on the mounting frame via a rotating shaft. The gear and the rack mesh with each other. A roller is fixedly installed on the rotating shaft. A screw is fixedly provided on the roller. A telescopic hose is fixedly connected to the air inlet end of the suction pump. The negative pressure box is fixedly installed on the side wall of the mounting frame. A suction head is fixedly installed at the bottom end of the negative pressure box. The negative pressure box is connected to the telescopic hose via a connecting pipe. A drain pipe is fixedly connected to the air outlet end of the suction pump.

[0006] As a preferred embodiment of the aquaculture microfiltration equipment of this utility model, the filtration equipment includes a filter box and a support frame. The filter box is fixedly installed on the support frame. A box cover is detachably installed on the top of the filter box. A water inlet pipe is fixedly installed on the top of the box cover. The water inlet pipe communicates with the interior of the filter box.

[0007] In a preferred embodiment of the aquaculture microfiltration machine equipment described in this utility model, the filter assembly includes a guide rail and a fixed frame. The guide rail is fixedly installed on both ends of the inner wall of the filter box, and slide bars are fixedly installed on both ends of the fixed frame. The slide bars are locked on the guide rail, and the slide bars and the guide rail are slidably connected.

[0008] In a preferred embodiment of the aquaculture microfiltration machine equipment of this utility model, a filter screen plate is fixedly installed inside the fixed frame, a sealing plate is fixedly installed at one end of the fixed frame, a through groove is provided on the side wall of the filter box for the sealing plate to pass through, and a handle is fixedly installed on the sealing plate.

[0009] In a preferred embodiment of the aquaculture microfiltration machine equipment described in this utility model, the rack is fixedly installed on the inner wall of the filter box, the multi-stage electric push rod is fixedly installed on the side wall of the filter box, the rotating shaft is rotatably mounted on the mounting frame, and the gear is fixedly installed at both ends of the rotating shaft.

[0010] In a preferred embodiment of the aquaculture microfiltration machine equipment described in this utility model, the sludge suction pump is fixedly installed on the outer wall of the filter box, and the telescopic hose extends through the side wall of the filter box into the interior of the filter box.

[0011] The beneficial effects of this utility model are: 1. Through the anti-clogging structure, the mounting frame is moved by a multi-stage electric push rod, and the roller rotates in conjunction with the meshing transmission of gears and racks. The nail teeth mechanically loosen the impurities on the surface of the filter screen, and at the same time, the negative pressure generated by the suction pump is used to remove the loose impurities in time through the suction head. This can efficiently remove impurities attached to the screen, prevent clogging, ensure that the filter screen maintains good filtration performance for a long time, reduce the frequency of equipment downtime maintenance due to clogging, and improve the stability and working efficiency of the aquaculture filtration system. 2. The filter components make the disassembly and installation of the filter screen convenient and labor-saving, allowing maintenance personnel to quickly complete cleaning or replacement work. The interlocking design of the sealing plate and the through groove ensures the airtightness of the filter box and prevents water leakage, while ensuring the stability and efficiency of the filtration process and reducing the difficulty of daily maintenance. It is suitable for the needs of continuous operation and convenient maintenance of equipment in aquaculture scenarios. Attached Figure Description

A water inlet pipe 14 is fixedly installed on the top of the box cover 13. The water inlet pipe 14 communicates with the interior of the filter box 11. The filter assembly 2 includes a guide rail 201 and a fixed frame 202. The guide rail 201 is fixedly installed on both ends of the inner wall of the filter box 11. Slide strips 204 are fixedly installed on both ends of the fixed frame 202. The slide strips 204 are snapped on the guide rail 201 and are slidably connected to the guide rail 201. A filter screen plate 203 is fixedly installed inside the fixed frame 202. A sealing plate 205 is fixedly installed on one end of the fixed frame 202. A through groove is provided on the side wall of the filter box 11 for the sealing plate 205 to pass through. The sealing plate 205 is snapped in the through groove and seals the through groove. A handle is fixedly installed on the sealing plate 205.

[0016] During use, the fixed frame 202 is engaged with the guide rail 201 on the inner wall of the filter box 11 by the sliding strip 204, and the sealing plate 205 is engaged in the through groove on the side wall of the filter box 11 to achieve a seal. Then, the aquaculture water to be filtered is introduced into the filter box 11 through the water inlet pipe 14. After the water enters, it flows through the filter screen 203. The filter screen 203 intercepts and filters the impurities in the water. When it is necessary to clean the filter screen 203, the handle on the sealing plate 205 can be held, and the fixed frame 202 and the filter screen 203 can be pulled out from the filter box 11 by the sliding action of the sliding strip 204 along the guide rail 201. After cleaning or maintenance, it can be pushed back to its original position. Example 2

[0017] Refer to attached figure Figure 4 - Appendix Figure 6 This is the second embodiment of the present invention, which differs from the first embodiment in that: The anti-clogging structure 3 includes a rack 301, a multi-stage electric push rod 302, a suction pump 307, and a negative pressure box 308. The rack 301 is fixedly installed on the inner wall of the filter box 11, and the rack 301 is above the filter screen plate 203. The multi-stage electric push rod 302 is fixedly installed on the side wall of the filter box 11. The telescopic end of the multi-stage electric push rod 302 is fixedly installed with a mounting bracket 303. The mounting bracket 303 passes through and rotatably installs a rotating shaft 304. Gears 305 are fixedly installed at both ends of the rotating shaft 304. The gears 305 are on the rack 301, and the gears 305 and the rack 301 mesh with each other. A roller 306 is fixedly installed on the rotating shaft 304. The roller 306 is fixedly provided with nail teeth. The suction pump 307 is fixedly installed on the outer wall of the filter box 11.
