Description

Technical Field

[0001] The present invention relates to the technical fields of fish tanks and landscape fish ponds, and particularly to a self-circulating water purification system. Background Art

[0002] Chinese Patent Grant Publication No. CN203590856U, with a grant publication date of May 14, 2014, discloses a new type of side filtration device for fish tanks. The main body is of a cuboid structure. A water flow baffle is arranged in the middle of the main body. The side of the water flow baffle is a filtration chamber. A water flow outlet is arranged at the top of the filtration chamber. A water flow inlet is arranged at the bottom of the filtration baffle. A filtration baffle perpendicular to the water flow baffle is arranged on the filtration baffle. One side of the filtration baffle is the filtration chamber, and the other side is the sewage chamber. A sewage inlet is arranged at the bottom of the sewage chamber. A water pump is arranged in the filtration chamber, and filter cotton is arranged in the filtration chamber. The side design of the filtration device of the present utility model can be directly integrated with the fish tank or can be placed in the fish tank after being made separately. The defects of this prior art are as follows:

[0003] 1. The device relies on the height difference between the sewage chamber and the filtration chamber to achieve water flow circulation. If the power of the water pump does not match the height difference properly, such as the water pumping rate of the water pump > the gravity water inlet rate, it may cause the filtration chamber to dry up or the sewage to overflow.

[0004] 2. The sewage inlet is only located at a single bottom position and cannot cover the entire bottom of the fish tank. For example, dead water areas are likely to form in the corner areas of a square fish tank.

[0005] 3. Only filter cotton (physical filtration layer) is arranged in the filtration chamber, resulting in insufficient specific surface area for nitrifying bacteria to attach, and low biochemical filtration efficiency; and the filter cotton needs to be replaced frequently, otherwise it is difficult to ensure water quality.

[0006] 4. The pores of the filter cotton are too small and are in direct contact with the sewage, which is easy to form a biofilm blockage, causing the water flow to overflow the filtration chamber. Therefore, the filter cotton needs to be replaced frequently, resulting in the destruction of the stability of the bacterial community.

[0007] In view of this situation, improvement is urgently needed. Summary of the Invention

[0008] Based on this, the purpose of the present invention is to provide a self-circulating water purification system, which can achieve continuous water flow circulation, reduce the purification dead water area, ensure that the bacterial community obtains the maximum digestive nutrition due to a comprehensive and stable water flow, thereby eliminating harmful substances such as ammonia, nitrogen, nitrate, and nitrite in the water quality, avoiding the generation of hydrogen sulfide at the same time, and maintaining good water purification function.

[0009] The present invention provides a self - circulating water purification system, including a breeding space body and a self - circulating purification system. The self - circulating purification system includes a diversion box, a water pump, an anti - block cotton layer, and a control device. The control device is installed on one side of the upper part of the breeding space body. The water pump is arranged in the diversion box and is electrically connected to the control device. The diversion box is arranged at the bottom of the inner cavity of the breeding space body. The top of the diversion box is formed with a water - seepage diversion plate communicating with the inner cavity of the diversion box. The anti - block cotton layer is arranged on the upper surface of the water - seepage diversion plate. A bacterial bed layer is laid on the upper surface of the anti - block cotton layer. A number of leakage holes are orderly and evenly arranged on the surface of the water - seepage diversion plate. A number of partition plates are arranged along the length direction between the lower surface of the water - seepage diversion plate and the bottom of the inner cavity of the diversion box, so as to divide the inner cavity of the diversion box into multiple flow channels. One side in the width direction of each partition plate is connected to one inner side wall of the diversion box, and a gap is formed between the other side in its width direction and the inner side wall of the diversion box. Each flow channel communicates with the gap. The water pump is installed on one side of the inner cavity of the diversion box, and the water inlet of the water pump is arranged in the inner cavity of the diversion box, and its water outlet extends out of the upper surface of the bacterial bed layer.

[0010] Preferably, the bacterial bed layer is set as any one of granite, stream stone, pebble, coral stone, volcanic stone, porous stone, ceramic ring, and ceramic fragments.

[0011] Preferably, when the bacterial bed layer is set as any one of granite, stream stone, pebble, coral stone, volcanic stone, porous stone, ceramic ring, and ceramic fragments, it is mixed with medical stone particles or activated carbon.

[0012] Preferably, the thickness of the bacterial bed layer is set as N, where N≥1 cm.

[0013] Preferably, the density of the leakage holes of the water - seepage diversion plate gradually changes from sparse to dense and the aperture gradually changes from small to large from the side close to the water pump to the side far from the water pump, so as to obtain a uniform water seepage rate.

[0014] Preferably, the breeding space body is set as a fish tank or a landscape fish pond.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. The water pump is installed on one side of the inner cavity of the diversion box and is electrically connected to the control device. The water inlet of the water pump is arranged in the inner cavity of the diversion box, and its water outlet extends out of the upper surface of the bacterial bed layer, realizing continuous water flow circulation and purification actions.

[0017] 2. A water seepage diversion plate communicating with the inner cavity of the diversion box is formed at the top of the diversion box. The anti-blocking cotton layer is arranged on the upper surface of the water seepage diversion plate. By arranging the anti-blocking cotton layer, fish excrement and debris of the bacteria bed layer are prevented from blocking the leakage holes. The bacteria bed layer is laid on the upper surface of the anti-blocking cotton layer. The leakage hole density of the water seepage diversion plate gradually changes from sparse to dense from the side close to the water pump to the side far from the water pump, and the hole diameter gradually changes from small to large. On the one hand, the water seepage uniformity during the water circulation filtration process is improved, and on the other hand, the dead water area of the bacteria bed layer is reduced. Moreover, by arranging the bacteria bed layer, it is ensured that the bacteria can obtain the maximum digestion nutrition due to the comprehensive and stable water flow, thereby eliminating harmful substances such as ammonia, nitrogen, nitrate, and nitrite in the water quality, avoiding the generation of hydrogen sulfide at the same time, and being able to maintain a good water purification function for a long time to obtain clean water quality.

[0018] 3. A plurality of partition plates are arranged between the lower surface of the water seepage diversion plate and the bottom of the inner cavity of the diversion box along its length direction, so as to divide the inner cavity of the diversion box into multiple flow channels. One side in the width direction of each partition plate is connected to one inner side wall of the diversion box, and a gap is formed between the other side in its width direction and the inner side wall of the diversion box. Through such a structural setting, the water seepage diversion uniformity of the diversion plate is improved. BRIEF DESCRIPTION OF THE DRAWINGS
