Description

Technical Field

[0001] This utility model relates to the field of leech farming technology, specifically a multi-layer three-dimensional leech farming box. Background Technology

[0002] Leeches are important aquatic organisms widely used in traditional Chinese medicine, ecological restoration, and biomedical research. Leeches possess unique medicinal value, allowing for the extraction of medicinal components used to treat various diseases, thus increasing the demand for their cultivation. Leech farming not only provides a stable supply to the medicinal materials market but also brings considerable economic benefits to farmers. Leech farming typically requires careful management of water quality, temperature, and the farming environment to promote their healthy growth and reproduction.

[0003] Patent CN217771153U discloses a multi-layer leech farming device, including a multi-layer support structure. The lowest layer of the support structure has a filter box, and the upper layers have farming boxes. The filter box pumps water to the top farming box, and the water in each farming box flows downwards layer by layer until it enters the filter box, achieving water circulation. Filter purification blocks are placed inside the filter boxes, and floating boards are placed on the surface of the water in the farming boxes. An aeration device is installed in each farming box. This invention features a multi-layered, three-dimensional structure, saving space and facilitating management. Water in each layer automatically flows to the next layer when it reaches a certain height, up to the fourth layer, and then back to the first layer, in a continuous cycle, making it more ecological and environmentally friendly, and saving water resources. The inner side of the farming box near the top uses polypropylene mesh to prevent leeches from escaping, and plastic foam boards float on the water surface, providing shade for the leeches and allowing them to attach and rest beneath them.

[0004] While existing leech farming devices can achieve water circulation, the inlet of their circulation pipes lacks an effective protective structure, making it highly likely that leeches will accidentally enter the circulation pipes with the water flow. In this situation, leeches may not only accidentally flow from the upper tanks into the lower tanks, causing chaos in farming management, but may also clog the circulation pipes, severely affecting the normal operation of the entire water circulation system. Furthermore, the overflow and recirculation method cannot effectively remove leech excrement from the tanks. This design flaw significantly reduces farming efficiency and the stability of water quality management. Therefore, to overcome these problems, we propose a multi-layered, three-dimensional leech farming tank to further optimize the leech farming environment and improve the safety of the circulating water system. Utility Model Content

[0005] The purpose of this invention is to provide a multi-layer, three-dimensional leech breeding box to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multi-layered, three-dimensional leech breeding tank includes a multi-layered support frame, which serves as the main framework to support the components of each layer and achieve a three-dimensional layout. A filter box is placed at the bottom of the inner wall of the multi-layered support frame for multi-stage filtration of wastewater and storage of purified water. A water pump is installed in the filter box to deliver purified water from the clear water tank to the water supply pipe. A water supply pipe is located on the left side of the multi-layered support frame to distribute the water output from the water pump to the water supply branch pipes of each layer. The output end of the water pump is connected to the input end of the water supply pipe. The outer wall of the water supply pipe has multiple water supply branch pipes arranged vertically at equal intervals to provide an independent water inlet channel for each layer of the breeding tank. The output end of the water supply branch pipe passes through the left side of the multi-layered support frame and is connected to a water inlet hose, injecting water into the breeding tank through a fixed vertical pipe.

[0008] Multiple support partitions are arranged equidistantly on the left and right sides of the inner wall of the multi-layer support frame to support the breeding box and fix its position. The breeding box is placed on the top of the support partition, providing space for leech breeding and enabling layered management. A perforated partition is provided inside the breeding box near the bottom to isolate the leeches from the bottom sewage, allowing excrement to sink and be discharged through the sewage pipe. A fixed vertical pipe is installed through the top of the perforated partition and near the left side. The output end of the water inlet hose is located inside the fixed vertical pipe, fixing the water inlet hose and guiding the water flow vertically into the breeding box.

[0009] The bottom right side of the breeding box is equipped with a sewage pipe that discharges sewage and excrement to the return pipe. The sewage pipe is equipped with a solenoid valve to control the timing of sewage discharge. Both the solenoid valve and the water pump are connected to an external power supply and controller. The solenoid valve and the water pump work together. When the water pump delivers water into the breeding box, the solenoid valve opens simultaneously, forming a water flow in the breeding box. This can quickly discharge the leech excrement and replace the water in the breeding box. The output water volume controlled by the solenoid valve is equal to the water delivery volume of the water pump to prevent excessive water overflow from the breeding box.

[0010] The right side of the multi-layer support is equipped with a return pipe to collect sewage from each layer and guide it back to the filter box. The outer wall of the return pipe is equipped with multiple return hoses arranged at equal intervals. The input end of the return hose is threaded to the output end of the sewage pipe. The return hose connects the sewage pipe and the return pipe to realize directional sewage return. The output end of the return pipe is connected to the filter box.

[0011] Preferably, the filter box is provided with a primary filter tank, a secondary filter tank, a tertiary filter tank and a clear water tank from right to left. The primary filter tank uses a stainless steel filter screen to filter large particulate impurities, the secondary filter tank uses activated carbon to adsorb fine suspended solids and organic matter, and the tertiary filter tank uses quartz sand or ceramic filter element for fine filtration. The top of the filter box is provided with a covered water inlet pipe to replenish clean water and prevent impurities from entering.

[0012] Preferably, the output end of the return pipe is connected to the primary filtration tank, and the water pump is located in the clear water tank.

[0013] Preferably, the top of the supporting partition is provided with a positioning frame, and the bottom of the breeding box is located in the positioning frame to limit the lateral displacement of the breeding box and ensure its stable placement. The top right side of the positioning frame is provided with a clearance groove to avoid interference between the sewage pipe and the positioning frame.

[0014] Preferably, the right side of the support partition has a U-shaped clearance opening in the middle to avoid the solenoid valve, providing installation space for the solenoid valve.

[0015] Preferably, the connection between the return hose and the drain pipe is located above the U-shaped clearance opening, which facilitates the assembly and disassembly of the drain pipe and the return hose.

[0016] Preferably, the inner wall of the breeding box is provided with a frame-shaped support near the bottom, and the bottom of the hollowed-out partition plate is attached to the top of the frame-shaped support to support the hollowed-out partition plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This multi-layered three-dimensional leech breeding box uses a hollowed-out partition to separate the leech activity area from the sewage discharge area. Combined with the coordinated control of solenoid valves and water pumps, it prevents leeches from entering the circulation pipe with the water flow while discharging sewage, thus ensuring smooth water circulation.

[0019] 2. This multi-layered, three-dimensional leech breeding tank features a multi-stage filtration system that purifies wastewater step by step. Combined with a directional sewage discharge design, it quickly removes leech excrement, maintains water cleanliness, and reduces the risk of disease transmission. Attached Figure Description
