Description

Technical Field

[0001] This utility model relates to a water treatment device for aquaculture. Background Technology

[0002] With the rapid development of aquaculture, intensive and high-density farming models have become increasingly common, making water quality management a key factor affecting the yield and quality of aquatic products. In traditional farming, uneaten feed, feces, algae, and harmful substances such as ammonia nitrogen and nitrite easily accumulate in the water, leading to water quality deterioration and causing problems such as frequent disease outbreaks, slow growth of farmed organisms, and even large-scale mortality.

[0003] Currently, common methods for treating aquaculture water mainly include physical filtration, chemical treatment, and biological purification. Physical filtration (such as sieves and sand filters) is the most basic and crucial step in water filtration.

[0004] In existing technologies, physical filtration relies on pumping water from ponds into a treatment tank, where passive filtration is achieved through contact with a screen.

[0005] However, the surface of the screen becomes clogged with dirt, resulting in reduced water flow efficiency and insufficient filtration capacity.

[0006] Therefore, the screen needs to be cleaned, which is quite time-consuming.

[0007] Based on the above problems, we designed a water treatment device for aquaculture that can quickly clean the water. Utility Model Content

[0008] The purpose of this invention is to provide a water treatment device for aquaculture that can quickly clean the water.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A water treatment device for aquaculture includes a water passage tank and a coarse filter device mounted horizontally on the water passage tank. A drive device is installed on the coarse filter device, and the drive device drives a sliding cleaning unit. The sliding cleaning unit moves along the coarse filter device, and as the sliding cleaning unit moves, the particles deposited in the coarse filter device are pushed out.

[0011] Preferably, the water passage includes a pool body, with drainage ditches cast on both sides of the pool body. The two ends of the drainage ditches are connected. A support is fixed above the pool body. The coarse filter is installed via the support. Particles pushed out by the sliding cleaning unit fall into the pool body, and the filtered water falls into the pool body.

[0012] Preferably, the coarse filtration device includes a filter tube with an inlet pipe welded to its middle section. Two through slots are formed at the bottom of the filter tube, and a filter screen is welded into each slot, facing the pool below. The filter tube is fixedly installed via a bracket. An upper bracket is installed near both ends of the top of the filter tube. A transverse groove is machined within the upper bracket. Plugs are slidably installed at both ends of the filter tube. A slider is fixed to the outer end face of each plug, and the slider slides along the groove. A guide rod is transversely arranged within the groove, passing through the slider. A spring is fitted onto the guide rod, pushing the slider towards the filter tube, at which point the plug seals both ends of the filter tube. The plug has a through hole.

[0013] Preferably, the driving device includes a drive wheel rotatably mounted on the end of the upper bracket, a drive rope is assembled between the drive wheels at both ends, the drive rope passes through the filter tube and through the through hole, a drive motor is fixed to the outer end of the upper bracket on one side, the drive motor drives the drive wheel on one side to rotate, the sliding cleaning unit is fixed to the drive rope, and as the drive rope rotates, the sliding cleaning unit pushes out the deposited particles in the filter tube.

[0014] Preferably, the sliding cleaning unit includes a movable body with rope-threading portions processed at both ends. The transmission rope passes through the rope-threading portions and is fixed to the transmission rope with screws. A rubber scraper is clamped on the outer wall of the movable body, and the rubber scraper acts on the inner wall of the filter tube. A medium-diameter portion is processed on the outer wall of the movable body, and bristles are embedded in the medium-diameter portion. The bristles act on the inner wall of the filter tube. An outer conical surface is formed between the medium-diameter portion and the rope-threading portions. The diameter of the outer conical surface gradually decreases towards the rope-threading portion. As the transmission rope rotates, the rope-threading portion acts on the plug and pushes the plug out.

[0015] Preferably, the plug has a tapered guide surface through which it is inserted into the filter tube.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This device adopts a filter tube design concept. By arranging the filter screen downwards, water permeates through gravity, intercepting coarse particles inside the filter tube. A drive device moves the sliding cleaning unit along the filter tube, which can quickly clean the filter tube and restore its filtration capacity. The cleaning efficiency is high, and no manual intervention is required, making the cleaning process relatively safe.

[0018] This device has a simple structure and low cost, making it suitable for widespread use. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please refer to Figure 1 As shown, this utility model is a water treatment device for aquaculture, including a water passage tank 1 and a coarse filter device 2 mounted horizontally on the water passage tank 1. A driving device 3 is installed on the coarse filter device 2, and the driving device 3 drives a sliding cleaning unit 4. The sliding cleaning unit 4 moves along the coarse filter device 2, and as the sliding cleaning unit 4 moves, the particles deposited in the coarse filter device 2 are pushed out.

[0025] In the above technical solution, a longer (greater than 5 meters) coarse filter device 2 is used to increase the filtration efficiency. The filtered particles are trapped inside the coarse filter device 2. As the drive device 3 drives the sliding cleaning unit 4 to slide, the trapped particles are pushed out of the coarse filter device 2, thus completing the cleaning.

[0026] Water and sludge are separated and stacked through the water-passing pool 1.

[0027] See Figure 1 As shown, the water tank 1 includes a tank body 11, and drainage ditches 12 are formed on both sides of the tank body 11. The two ends of the drainage ditches 12 are connected. A support 13 is fixed above the tank body 11. The coarse filter device 2 is installed via the support 13. Particles pushed out by the sliding cleaning unit 4 fall into the tank body 11, and the filtered water falls into the tank body 11.

[0028] In the above technical solution, the filtered water is collected by the pool body 11, and a drain pipe 199 is inserted into the side of the pool body 11 as needed, or the water is discharged by pumping.

[0029] The sludge pushed out by the sliding cleaning unit 4 is collected through the drainage ditch 12, which is open at both ends and can scrape out the sludge.

[0030] See Figure 1 , Figure 2 and Figure 3 As shown, the coarse filtration device 2 includes a filter pipe 21. A water inlet pipe 22 is welded to the middle of the filter pipe 21. The water inlet pipe 22 is used to connect to a water pump. The water pump draws sewage and sends it into the filter pipe 21. The lower part of the filter pipe 21 has two through slots, left and right, with an arc of 1π. A filter screen 24 is welded into the through slots. The filter screen 24 is a stainless steel filter screen with a mesh size of 60 mesh. The filter screen 24 faces the pool body 11 below. The filter pipe 21 is fixedly installed by the bracket 13. An upper bracket 25 is installed near both ends of the top of the filter pipe 21. A transverse groove 26 is machined inside the upper bracket 25. Plugs 27 are slidably installed at both ends of the filter tube 21. A slider 28 is fixed at the outer end face of the plug 27. The slider 28 slides along the groove 26. A guide rod 29 is arranged transversely inside the groove 26. The guide rod 29 passes through the slider 28. A spring 210 is sleeved on the guide rod 29. The spring 210 pushes the slider 28 to move towards the filter tube 21. At this time, the plug 27 closes both ends of the filter tube 21. The plug 27 has a through hole 211.

[0031] In the above technical solution, the spring 210 provides a pushing force to the slider 28, so that the plug 27 can be sealed at the end of the filter tube 21.

[0032] Water is pumped into the filter tube 21 at a low flow rate, keeping the water level below the height of the through hole 211 and exiting through the filter screen 24 below. When water overflows from the through hole 211 while the inflow rate remains constant, it indicates that the filter screen 24 has insufficient filtration capacity. At this point, the water supply needs to be stopped, and the sliding cleaning unit 4 is moved by the drive device 2. When the sliding cleaning unit 4 moves, it pushes open the plug 27 to facilitate the removal of deposited dirt.

[0033] See Figure 1 and Figure 2As shown, the driving device 3 includes a transmission wheel 31 rotatably mounted on the end of the upper bracket 25. A transmission rope 32 is assembled between the transmission wheels 31 at both ends. The transmission rope 32 passes through the filter tube 21 and through the through hole 211. A drive motor 33 is fixed to the outer end of the upper bracket 25 on one side. The drive motor 33 drives the transmission wheel 31 on one side to rotate. The sliding cleaning unit 4 is fixed to the transmission rope 32. As the transmission rope 32 rotates, the sliding cleaning unit 4 pushes out the deposited particles in the filter tube 21.

[0034] In the above technical solution, the transmission rope 32 is fitted with the through hole 211 with a clearance.

[0035] See Figure 4 As shown, the sliding cleaning unit 4 includes a movable body 41, with rope-threading portions 42 machined at both ends of the movable body 41. The transmission rope 32 passes through the rope-threading portions 42 and is fixed to the transmission rope 32 with screws. A rubber scraper 43 is clamped on the outer wall of the movable body 41 and acts on the inner wall of the filter tube 21. A medium-diameter portion 45 is machined on the outer wall of the movable body 41, and bristles 44 are embedded in the medium-diameter portion 45. The bristles 44 act on the inner wall of the filter tube 21. An outer conical surface 46 is formed between the medium-diameter portion 45 and the rope-threading portions 42. The diameter of the outer conical surface gradually decreases towards the rope-threading portion. As the transmission rope rotates, the rope-threading portion acts on the plug and pushes the plug out.

[0036] In the above technical solution, the filter screen is cleaned by the brush bristles 44, and the cleaned dirt is scraped off by the rubber scraper 42.

[0037] The diameter of the moving body 41 is smaller than the inner diameter of the filter tube 21.

[0038] See Figure 2 As shown, the plug 27 has a tapered guide surface 277 through which it is inserted into the filter tube.

[0039] The guide surface 277 facilitates the insertion of the plug 27.
