Description

Technical Field

[0001] This utility model relates to the field of aquaculture purification technology, specifically a water purification device for fish farming. Background Technology

[0002] In aquaculture, to ensure the survival rate of farmed fish, fishponds need to be cleaned regularly to remove fish waste, uneaten food, and other debris. Current technologies generally employ two methods for water exchange. One is a complete drainage method, where the fish are removed from the pond, the pond is drained, and fresh water is added. The removed fish are then returned to the pond. While this method effectively removes wastewater, it significantly impacts fish survival, often resulting in the death of a large number of fish during a single removal process. The other method is a circulating method, where wastewater is continuously pumped out of the pond, purified, and then reintroduced.

[0003] The continuous extraction of wastewater for purification makes the filter plates of the filtration device prone to clogging, resulting in reduced filtration efficiency. Therefore, the filter plates need to be cleaned or replaced frequently, which is quite tedious. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a water purification device for fish farming, which has the advantage of easily removing filtered impurities and avoids the tedious problem of frequently cleaning the filter plate.

[0005] To facilitate the removal of filtered impurities, this utility model provides the following technical solution:

The device also includes:

[0007] The impurity removal assembly includes a filter plate, which is slidably installed on the inner wall of the filter box. A first spring is fixedly connected between the filter plate and the filter box. An impurity removal pipe is fixedly connected to the side wall of the filter box above the filter plate. A partition is fixedly connected to the top of the filter plate, and the partition can isolate the impurity removal pipe. A connecting pipe is fixedly connected to the side wall of the impurity removal pipe. The connecting pipe communicates with the filter box, and the input end of the connecting pipe is located below the filter plate. A filter screen is provided between the connecting pipe and the filter box.

[0014] Beneficial effects

[0015] This utility model provides a water purification device for fish farming, which has the following beneficial effects:

[0016] This water purification equipment for fish farming uses a filter plate to filter water.

As a result, water and impurities will flow into the inner cavity of the impurity removal pipe, where the impurities will remain. When there are too many impurities, the blockage block will slide down to the outside of the impurity removal pipe, thus completing the sewage discharge. 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] Reference Figures 1-5 A water purification device for fish farming includes a filter box 1, a water pump 101 fixedly connected to the top of the filter box 1, an inlet pipe 102 fixedly connected to the input end of the water pump 101, a filter assembly 2 installed on the inner wall of the filter box 1 for filtering impurities, and a dirt removal assembly 3 installed on the inner wall of the filter box 1 for removing the filtered impurities. The device also includes:

[0025] The impurity removal assembly 3 includes a filter plate 301, which is slidably installed on the inner wall of the filter box 1. A first spring 302 is fixedly connected between the filter plate 301 and the filter box 1. An impurity removal pipe 303 is fixedly connected to the side wall of the filter box 1 above the filter plate 301. A partition 304 is fixedly connected to the top of the filter plate 301, and the partition 304 can isolate the impurity removal pipe 303. A connecting pipe 305 is fixedly connected to the side wall of the impurity removal pipe 303. The connecting pipe 305 is connected to the filter box 1, and the input end of the connecting pipe 305 is located below the filter plate 301. A filter screen is provided between the connecting pipe 305 and the filter box 1.

[0026] A connecting bracket 306 is fixedly connected to the inner wall of the impurity removal pipe 303, and a connecting column 307 is fixedly connected to the bottom of the connecting bracket 306.

[0027] A blocking block 308 is slidably connected to the side wall of the connecting column 307. The blocking block 308 is slidably connected to the impurity removal tube 303 and can extend to the outside of the impurity removal tube 303. A second spring 309 is fixedly connected between the blocking block 308 and the connecting frame 306.

[0028] It should be noted that: the water pump 101 draws water from the water tank to the filter box 1 through the inlet pipe 102. The filter plate 301 installed inside the filter box 1 filters the water. Impurities in the water are blocked above the filter plate 301. When too many impurities obstruct the filter plate 301, the impact force of the water on the filter plate 301 increases, causing the filter plate 301 to slide down the baffle 304, exposing the inlet of the impurity removal pipe 303. Therefore, the water and impurities above the filter plate 301 flow into the impurity removal pipe 303. The inner cavity, where the filter screen located between the connecting pipe 305 and the filter box 1 will intercept impurities, and the filtered water continues to enter the filter box 1. Impurities will remain in the inner cavity of the impurity removal pipe 303. If there are too many impurities in the inner cavity of the impurity removal pipe 303, the pressure in the inner cavity of the impurity removal pipe 303 will increase, which will cause the blockage block 308 to slide down to the outside of the impurity removal pipe 303. At this time, the sewage in the impurity removal pipe 303 will flow out, thus completing the sewage discharge. The first spring 302 and the second spring 309 can return the filter plate 301 and the blockage block 308 to their original positions.

[0029] Reference Figures 1-5 The filter assembly 2 includes a connecting plate 201, which is fixedly installed on the inner wall of the filter box 1, and a brush 202 is fixedly connected to the top of the connecting plate 201.

[0030] Multiple sets of brushes 202 are provided, and they are made of flexible material. The brushes 202 can penetrate the filter plate 301.

[0031] It should be noted that when excessive impurities above the filter plate 301 cause it to slide down, the brush 202 at the top of the connecting plate 201 will penetrate the filter plate 301 to clean the impurities inside the filter plate 301 and prevent it from becoming clogged.

[0032] Reference Figures 1-5 A locking post 4 is slidably connected to the inner wall of the partition 304, and a third spring 401 is fixedly connected between the locking post 4 and the inner wall of the partition 304.

[0033] The clamping post 4 can extend to the inner wall of the filter box 1, and the end of the clamping post 4 is set to be arc-shaped. The bottom of the filter box 1 is fixedly connected to the water outlet pipe 402.

[0034] It should be noted that the setting of the retaining post 4 creates a certain friction between the baffle 304 and the inner wall of the filter box 1, preventing the filter plate 301 from sliding down under normal water impact, thus causing water to be discharged from the impurity removal pipe 303 and making it difficult for the water to achieve the filtering effect.

[0035] Operation method: The water pump 101 draws water from the water tank to the filter box 1 through the water inlet pipe 102. The filter plate 301 installed in the inner cavity of the filter box 1 filters the water. Impurities in the water are blocked above the filter plate 301. When too many impurities obstruct the filter plate 301, the impact force of the water on the filter plate 301 increases, causing the filter plate 301 to slide down. The brush 202 on the top of the connecting plate 201 will penetrate the filter plate 301 to clean the impurities inside the filter plate 301 and prevent it from clogging.

[0036] As the baffle 304 slides down, it exposes the inlet of the impurity removal pipe 303. Therefore, the water and impurities above the filter plate 301 will flow into the inner cavity of the impurity removal pipe 303. The filter screen located between the connecting pipe 305 and the filter box 1 will intercept the impurities. The filtered water continues to enter the filter box 1, and the impurities will remain in the inner cavity of the impurity removal pipe 303. If there are too many impurities in the inner cavity of the impurity removal pipe 303, the pressure in the inner cavity of the impurity removal pipe 303 will increase, which will cause the blockage block 308 to slide down to the outside of the impurity removal pipe 303. At this time, the sewage in the impurity removal pipe 303 will flow out, thus completing the sewage discharge. The first spring 302 and the second spring 309 can return the filter plate 301 and the blockage block 308 to their original positions.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
