Description

Technical Field

[0001] The utility model relates to the technical field of fish tank water filtration, in particular to an external pneumatic filter. Background Art

[0002] The fish tank filter is a device used to purify water in fish farming equipment. Its purpose is to remove debris such as feces in the water, keep the water clear, free of harmful substances and pollution, and suitable for the growth of fish. Installing a filter on the fish tank to filter the water in the fish tank can not only raise fish well, but also reduce the number of water changes.

[0003] At present, the fish tank filters on the market are all composed of a filter body equipped with a water pump. The water in the fish tank is pumped into the filter by the water pump, and then the water is filtered by the filtering structure in the filter. The filtered water automatically flows back to the fish tank, thereby achieving the purpose of filtration. The fish tank also needs to be equipped with an oxygenating device, which injects oxygen into the water in the fish tank to ensure the oxygen content required for the normal growth of the fish.

[0004] Since both the oxygenating device and the filtering device are indispensable devices on the fish tank, the fish tank is usually equipped with these two devices, which will undoubtedly increase the cost of fish farming, and the oxygenating device and the filtering device will generate certain noise when working. Utility Model Content

[0005] In order to solve the above problem, that is, setting an oxygenating device and a filtering device on the fish tank will not only increase the cost of fish farming, but also produce a problem of high noise, the utility model proposes an external pneumatic filter, which includes a filter box, a filter assembly is arranged in the filter box, a water drain box is arranged on the side wall of the filter box, a water drain port is opened on the side wall of the filter box close to the water drain box, the filter box is connected with the water drain box through the water drain port, the water drain port is arranged below the filter assembly, and a water drain plate is arranged on the side surface of the water drain box away from the filter box; it also includes a water supply pipe, the side wall of the water supply pipe is connected with an inflation pipe, and the other end of the inflation pipe is connected with an air pump.

[0006] The utility model is further configured as follows: an air filling port is provided on the side wall of the upper water pipe, the air filling port and the upper water pipe are arranged at the same angle, and the air filling pipes are connected to each other.

[0007] The utility model is further configured as follows: the filter assembly comprises filter cotton, biochemical cotton and biochemical balls from top to bottom.

[0008] The utility model is further configured as follows: a plurality of convex strips are arranged in the water upper pipe, the plurality of convex strips are evenly arranged along the circumference of the water upper pipe, and the inflation port is arranged below the convex strips.

[0009] The beneficial effects of the utility model are:

[0010] 1. The air pump fills gas into the upper water pipe through the inflation pipe, so that bubbles are generated in the water in the upper water pipe. In the process of the bubbles floating upward, the water can be driven to flow, and then, under the continuous push of the bubbles, the water can flow into the filter box, thereby achieving the purpose of filtration. At the same time, the bubbles blown into the water can also achieve the purpose of oxygenation, and then by installing the device on the fish tank, the purposes of filtration and oxygenation can be achieved, which greatly saves the cost of fish farming, and only uses one air pump, which can also greatly reduce the noise during operation.

[0011] 2. By setting convex strips in the water supply pipe, the bubbles can be made finer during inflation, thereby better promoting the flow of water. In addition, the oxygen in the bubbles can be more fully integrated into the water, making the oxygen content in the water richer. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0019] The utility model proposes an external pneumatic filter, including a filter box 1, a filter assembly 4 is arranged in the filter box 1, and is used to filter impurities in water. A water discharge box 2 is integrally arranged on one side wall of the water tank, and a water discharge port 11 is opened on the surface of one side of the filter box 1 close to the water discharge box 2. The filter box 1 is connected with the filter box 1 through the water discharge port 11, so that the water in the filter box 1 can flow into the water discharge box 2, and the water discharge port 11 is arranged below the filter assembly 4.

[0020] A drain plate 21 is integrally provided on the surface of the drain tank 2 on one side facing away from the filter tank 1. The drain plate 21 is arranged in an arc shape and is arranged below the top edge of the filter tank 1, so that the water in the drain tank 2 can flow out along the drain plate 21. The drain tank 2 can be hung on the wall of the fish tank through the drain plate 21, so that the water flowing out of the drain tank 2 can flow back to the fish tank.

[0021] It also includes an upper water pipe 3, which is arranged at a right angle, one end of which extends into the water surface of the fish tank, and the other end of which extends into the top of the filter box 1. An air filling port 31 is provided on the side wall of the upper water pipe 3, and the air filling port 31 is connected to an air filling pipe 5, which is arranged below the water surface, and the other end of the air filling pipe 5 is connected to an air pump 6, which can fill the upper water pipe 3 through an air pipe. When gas is filled into the water in the upper water pipe 3, bubbles will be generated in the water, and the bubbles will drive the water to flow upward during the process of floating, and then flow into the filter box 1 along the upper water pipe 3.

[0022] The inflation port 31 is arranged at the same angle as the water supply pipe 3, so that the movement direction of the gas injected into the water supply pipe 3 is obliquely upward, which can better promote the flow of water.

[0023] A plurality of convex strips 32 are integrally provided on the inner wall of the water supply pipe 3. The cross section of the convex strips 32 is set to be triangular. The plurality of convex strips 32 are evenly arranged along the axial direction of the water supply pipe 3. The inflation port 31 is arranged below the convex strips 32. The convex strips 32 can divide the bubbles in the water supply pipe 3, and then divide the bubbles into more small bubbles, making the bubbles more refined, thereby better promoting the flow of water, and also enabling the oxygen in the bubbles to be more fully integrated into the water, making the oxygen content in the water richer.

[0024] The filter assembly 4 includes filter cotton 41, biochemical cotton 42 and biochemical ball 43, and the filter cotton 41, biochemical cotton 42 and biochemical ball 43 are arranged in order from top to bottom. The filter cotton 41 can filter out fish feces and impurities in the water, and the biochemical cotton 42 and biochemical ball 43 can filter out toxic and harmful substances such as ammonia nitrogen and nitrite in the water. The filtered water will flow into the water discharge tank 2 from the waterproof building, and then flow back to the fish tank along the water discharge plate 21.

[0025] It should be noted that, according to experiments, air bubbles can push the water in the water supply pipe 3 to flow upward by 8cm-10cm. Therefore, during installation, the height of the water outlet end of the water supply pipe 3 is set not higher than 8cm.

[0026] In summary, the air pump 6 in the utility model fills gas into the upper water pipe 3 through the inflation pipe 5, so that bubbles are generated in the water in the upper water pipe 3. In the process of the bubbles floating upward, the water can be driven to flow, and then under the continuous promotion of the bubbles, the water can flow into the filter box 1, thereby achieving the purpose of filtering. At the same time, the bubbles blown into the water can also achieve the purpose of oxygenation, and then by installing this device on the fish tank, the purpose of filtering and oxygenation can be achieved, which greatly saves the cost of fish farming, and only uses one air pump 6, which can also greatly reduce the noise during operation. By arranging the convex strips 32 in the upper water pipe 3, the bubbles can be made finer during inflation, thereby better promoting the flow of water, and the oxygen in the bubbles can be more fully integrated into the water, making the oxygen content in the water richer.
