Description

Technical Field

[0001] This utility model relates to the field of purification equipment technology, specifically to a circulating water purification device. Background Technology

[0002] Aquaculture is a production activity involving the breeding, cultivation, and harvesting of aquatic plants and animals under human control.

[0003] Currently, in the aquaculture process, in order to remove impurities or pollutants in the water that are not conducive to the growth of aquatic products, it is necessary to change the aquaculture water (seawater or freshwater) regularly. In order to save water resources, circulating water purification equipment is generally used to circulate and purify the aquaculture water, thereby providing a better aquaculture environment and ensuring the survival rate and quality of the aquatic products.

[0004] Existing circulating water purification equipment gradually accumulates dirt and sediment during use, especially when processing large amounts of water or air with high levels of impurities, causing the filter layer to easily become clogged. This clogging reduces the water permeability or air permeability of the filter layer, lowering purification efficiency and even rendering the purification effect completely ineffective.

[0005] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is the closest prior art. Utility Model Content

[0006] The purpose of this invention is to address the aforementioned shortcomings and provide a circulating water purification device.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a circulating water purification device, including a purification box set outside the aquaculture pond, a water guide pipe connected between the purification box and the aquaculture pond by a power pump, a return pipe for circulating the purified water back into the aquaculture pond on the purification box, and several spaced filter layers arranged inside the purification box for multi-stage filtration of the water in the aquaculture pond, with a first cleaning unit and a second cleaning unit respectively provided on both sides of each filter layer for cleaning impurities on the corresponding surface.

[0008] An external support mechanism is correspondingly disposed outside the filter layer, used to elastically support the filter layer and cooperate with the second cleaning unit to perform vibration cleaning on the surface of the filter layer.

[0009] Furthermore, the first cleaning unit includes a first vertical plate distributed on the water inlet side of the filter layer, and columnar cleaning strips uniformly disposed on the first vertical plate for scraping and cleaning impurities attached to the water inlet side surface of the filter layer.

[0011] Furthermore, a gear is coaxially mounted on the central shaft of the cam, and the external support mechanism includes a top block mounted on the top of the filter layer, a rack mounted on the top block corresponding to one side of the second vertical plate and meshing with the gear, a support frame mounted on the side of the top block away from the gear, and a spring mounted at the end corner of the support frame and connected to the filter layer.

[0012] Furthermore, movable blocks are provided on the first and second upright plates distributed on both sides of each filter layer;

[0013] The moving block moves accordingly on top of the top block.

[0014] Furthermore, each of the moving blocks is detachably provided with a movable crossbar on its upper outer side, and a lead screw and a guide rod are respectively adapted to be provided at both ends of the movable crossbar.

[0015] Furthermore, a fixed post is provided on the movable block, and a fixed plate is provided on the movable cross frame at the position corresponding to the fixed post. An inner ring is opened on the end face of the fixed plate, and a plug rod that is inserted into the fixed post is radially provided on the inner ring.

Detailed Implementation

[0026] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] like Figure 1-6 As shown, this utility model discloses a circulating water purification device for aquaculture, including a purification box 200 installed outside an aquaculture pond 100. A water guide pipe 201, which is supplied by a power pump, is installed between the purification box 200 and the aquaculture pond 100. A return pipe 202 is also installed on the purification box 200 for circulating the purified water back into the aquaculture pond 100. The purification box 200 is provided with several spaced filter layers 1 for multi-stage filtration of the water in the aquaculture pond 100. A first cleaning unit 2 and a second cleaning unit 3 for cleaning the corresponding surface impurities are respectively provided on both sides of each filter layer 1.

[0028] An external support mechanism 4 is disposed on the outside of the filter layer 1, which is used to elastically support the filter layer 1 and cooperate with the second cleaning unit 3 to perform vibration cleaning on the surface of the filter layer 1.

[0029] In practice, by connecting the aquaculture pond 100 and the purification tank 200 with a water pipe 201 and a return pipe 202, a water circulation channel can be established. The water pipe 201, which is pressurized and delivered from the aquaculture pond 100 by a power pump, enters the purification tank 200 and undergoes multi-stage filtration through several spaced filter layers 1. The water then circulates under the return flow of the return pipe 202, ensuring the removal of impurities in the water in the aquaculture pond 100, realizing the recycling of aquaculture water, and saving water resources.

[0030] Furthermore, the first cleaning unit 2 and the second cleaning unit 3, which are installed close to both sides of the filter layer 1, together with the external support mechanism 4, can simultaneously perform corresponding cleaning on the inlet and outlet sides of the filter layer 1, thereby ensuring the good filtration effect of the filter layer 1 and preventing the filter layer 1 from being blocked. This greatly improves the filtration effect of the purification box 200 and extends the service life of the purification box 200.

[0031] It should be noted that all filter layers 1 adopt a filter mesh structure with holes, and the mesh gap gradually decreases along the direction of water flow, which can perform multi-stage filtration and remove impurities of various particle sizes.

[0032] Furthermore, gravel and activated carbon filter layers can be deposited on the effluent side of the last filter layer 1 for further filtration.

[0033] In one embodiment, the first cleaning unit 2 includes a first vertical plate 21 distributed on the water inlet side of the filter layer 1, and cylindrical cleaning strips 22 uniformly disposed on the first vertical plate 21 for scraping and cleaning impurities attached to the water inlet side surface of the filter layer 1. This design, with the first vertical plate 21 vertically close to the filter layer 1 and the uniformly distributed cylindrical cleaning strips 22 mounted on the first vertical plate 21 near the end face of the filter layer 1, allows the cylindrical cleaning strips 22 to contact and scrape away impurities from the water inlet side mesh of the filter layer 1 during the movement of the first vertical plate 21, achieving a good cleaning effect.

[0034] In one embodiment, the second cleaning unit 3 includes a second vertical plate 31 distributed vertically on the water outlet side of the filter layer 1, and a cam 32 vertically slotted and rotatably mounted on the second vertical plate 31. This design, with the second vertical plate 31 vertically close to the water outlet side of the filter layer 1, and the cam 32 slotted and rotatably mounted on the surface of the second vertical plate 31, allows the filter layer 1 to periodically move up and down, back and forth, or left and right when an external force is applied to drive the cam 32 to rotate. In particular, if the surface of the cam 32 has a rapidly changing profile (such as a rapidly rising and falling slope), the filter layer 1 will generate strong vibrations during rotation, thereby achieving a vibration-based cleaning function.

[0035] In one embodiment, a gear 33 is coaxially mounted on the central shaft of the cam 32. The external support mechanism 4 includes a top block 41 mounted on the top of the filter layer 1, a rack 42 mounted on the top block 41 corresponding to one side of the second vertical plate 31 and meshing with the gear 33, a support frame 43 mounted on the side of the top block 41 away from the gear 33, and a spring 44 connected to the filter layer 1 mounted at the end corner of the support frame 43. With this design, the gear 33 coaxially welded on the central shaft of the cam 32, and the top block 41 and the rack 42 on the top block 41 corresponding to one side of the second vertical plate 31 and meshing with the gear 33, during the movement of the second vertical plate 31, the meshing of the rack 42 with the gear 33 will drive the gear 33 to rotate, thereby driving the cam 32 coaxially distributed on the gear 33 to rotate, thus realizing the vibration cleaning of the cam 32.

[0036] Furthermore, the support frame 43 welded to the other side of the top block 41 and the spring 44 installed at the corresponding position on the support frame 43 and elastically connected to the filter layer 1 can store and release energy in the interaction between the cam 32 and the filter layer 1. When the cam 32 rotates, the spring 44 will be compressed or stretched, thereby storing mechanical energy; when the movement of the cam 32 changes, the spring 44 will release the stored energy, helping to provide a smooth vibration process.

[0037] In one embodiment, a moving block 5 is provided on the first upright plate 21 and the second upright plate 31 distributed on both sides of each of the filter layers 1;

[0038] The moving block 5 moves accordingly on the top of the top block 41. With this design, the moving block 5, which is installed with screws on the top of the first vertical plate 21 and the second vertical plate 31 that are installed close to each other on both sides of the filter layer 1, will drive the cylindrical cleaning strip 22 on the first vertical plate 21 and the cam 32 on the second vertical plate 31 to perform corresponding cleaning operations on both sides of the filter layer 1 when the moving block 5 is moved on the top of the corresponding top block 41 by external force.

[0039] In one embodiment, a movable crossbeam 6 is detachably provided on the upper outer side of each of the moving blocks 5. A lead screw 7 and a guide rod 8 are respectively fitted to both ends of the movable crossbeam 6. This design, with the movable crossbeam 6 assembled on the upper outer side of each moving block 5, and the lead screw 7 with a slotted thread at one end and the guide rod 8 with a slotted sliding fit at the other end, causes the movable crossbeam 6, connected to the lead screw 7, to move linearly under the constraint of the guide rod 8 at the other end when the lead screw 7 rotates. This allows the moving blocks 5 mounted on the movable crossbeam 6 and the first cleaning unit 2 and the second cleaning unit 3 fixed on the moving blocks 5 to simultaneously clean both sides of the filter layer 1.

[0040] It should be noted that a motor is installed at one end of the lead screw 7.

[0041] In one embodiment, a fixed post 9 is provided on the moving block 5, and a fixed plate 91 is provided on the movable cross frame 6 at the position corresponding to the fixed post 9. An inner ring is provided on the end face of the fixed plate 91, and a plug rod that is inserted into the fixed post 9 is provided radially on the inner ring.

[0042] The fixing plate 91 is vertically inserted into the fixing column 9 to fix the moving block 5 on the movable crossbeam 6 and move with the movable crossbeam 6 to clean the filter layer 1 installed at the corresponding position of the moving block 5. This design, with the fixing column 9 welded to the moving block 5 and the fixing plate 91 welded to the corresponding position on the movable crossbeam 6, and the inner ring with a groove on the end face of the fixing plate 91, fixes the moving block 5 on the movable crossbeam 6. First, the fixing plate 91 is inserted into the fixing column 9, and then a rod is vertically inserted radially along the inner hole through the fixing column 9 to the bottom groove of the inner hole, thus fixing the moving block 5 on the movable crossbeam 6. During the movement of the movable crossbeam 6, the corresponding fixed moving block 5 is driven, and the first cleaning unit 2 and the second cleaning unit 3 installed on the lower side of the moving block 5 simultaneously clean the corresponding filter layer 1.

[0043] It should be noted that the detachable assembly of the movable crossbar 6 and the moving block 5 allows for simultaneous cleaning of one, two, or more, or all of the filter layers 1, depending on actual cleaning needs, making the operation simple.

If the specific posture changes, the directional indicators will also change accordingly.
