Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture equipment, in particular to a multi-pipeline filtering device which uses gas as a power source and can automatically clean and oxygenate. Background Art

[0002] At present, the treatment method of circulating aquaculture water is generally: aquaculture water, sedimentation tank, chlorine disinfection treatment, sand filter, vertical flow sedimentator, protein separator, ultraviolet disinfection, water storage, and entering the aquaculture pond. The circulating aquaculture water produced by the above treatment method has high energy consumption. Since the overall circulating water treatment route has high energy consumption and the terminal water storage has low dissolved oxygen content, it is easy to produce harmful substances. If it is directly used for aquaculture, there will be safety hazards, which increases the risk of aquaculture. When the water quality is good, there will be a lot of energy waste in a large number of invalid cycles. The present invention integrates the three functions of filtration, sedimentation and oxygenation, and can form a small circulation system in four aquaculture ponds, which can effectively reduce the invalid circulation and energy waste in the traditional circulating aquaculture process, increase the dissolved oxygen in the water body, reduce the amount of organic debris and other suspended matter in the water body, and reduce the risk of circulating aquaculture. Summary of the invention

[0003] The utility model aims to solve the deficiencies of the prior art and provides a secondary treatment device for circulating aquaculture water.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0009] The water outlet pipe comprises four pipes located at the outer edge of the top of the barrel body and provided with an external air pump oxygenation interface.

[0010] Furthermore, the input end of the water inlet pipe is located at the bottom of the barrel, and there are four of them. The valve can be adjusted according to demand to control the water inlet volume and source.

[0011] Furthermore, the quartz sand backwashing pipeline and the quartz sand backwashing pipeline fixing base are located at the center of the bottom of the barrel.

[0012] Furthermore, the quartz sand backwashing pipeline is connected to the air power pipeline of the external air pump, and the quartz sand backwashing is completed by air power.

[0013] Furthermore, after the quartz sand is backwashed, the dirt screening double-layer baffle screens out the dirt by gravity and discharges it through the sewage pipe.

[0014] Furthermore, it also includes water outlet pipes, including four water outlet pipes located on the outer edge of the top of the barrel body and provided with external air pump oxygenation interfaces.

[0015] Furthermore, the water outlet pipe takes in a large amount of air through an external air pump to add a large number of bubbles into the water body, thereby raising the liquid level and completing the oxygenation of the water body.

[0016] Furthermore, the water output at the water outlet can be adjusted by controlling the air intake in the four water outlet pipes.

[0017] The beneficial effects of the utility model are as follows: the utility model utilizes a quartz sand filter layer, an air-powered quartz sand backwashing device, and an oxygenated water outlet pipe, which not only increases the dissolved oxygen content of filtered water, reduces the amount of organic debris and other suspended matter, but also saves energy consumed by a large circulation system through a small circulation system, reduces steps such as manual cleaning of sand filters, and reduces the risk of circulating water aquaculture. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In the figure: barrel 1, including a quartz sand filter layer;

[0020] The bottom water inlet pipe includes four water inlet pipes 21, 22, 23, and 24 with valves at the bottom of the barrel;

[0021] The air-powered quartz sand backwashing device 3 includes a quartz sand backwashing pipeline 31, a quartz sand backwashing pipeline fixing base 32, an air-powered pipeline 33 connected to an external air pump, a dirt screening double-layer baffle 34, a backwashing cover plate 35, and a sewage pipeline 36. The quartz sand backwashing pipeline 31 and the quartz sand backwashing pipeline fixing base 32 are located at the bottom center of the barrel body 1;

[0022] The air-powered oxygenation water outlet pipe comprises four water outlet pipes 41, 42, 43, 44 located at the outer edge of the top of the barrel body and having an external air pump oxygenation pipe;

[0023] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings. DETAILED DESCRIPTION

[0024] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0025] As shown in the figure, this embodiment includes:

[0026] The barrel 1 includes a quartz sand filter layer;

[0027] The bottom water inlet pipe includes four water inlet pipes 21, 22, 23, and 24 with valves at the bottom of the barrel;

[0028] The pneumatic quartz sand backwashing device includes a quartz sand backwashing pipeline 31, a quartz sand backwashing pipeline fixing base 32, an pneumatic pipeline 33 connected to an external air pump, a dirt screening double-layer baffle 34, a backwashing cover plate 35, and a sewage pipeline 36. The quartz sand backwashing pipeline 31 and the quartz sand backwashing pipeline fixing base 32 are located at the bottom center of the barrel body 1;

[0029] The oxygenated water outlet pipe comprises four water outlet pipes 41, 42, 43, 44 located at the outer edge of the top of the barrel body and having an external air pump oxygenation pipe.

[0030] When the utility model is used, the upstream water enters the barrel body 1 through the four-way water inlet pipes 21, 22, 23, and 24 for filtration. After the water passes through the sand filter inside the barrel body 1, the outlet pipes 41, 42, 43, and 44 connected to the air pump aeration pipe oxygenate the water in the pipe and at the same time, the liquid level in the pipe is raised through bubbles and the water is discharged, so as to increase the pressure in the pipe to achieve the effect of accelerating the water flow and aeration; the high-speed water flow flows from the outlet end to the lower-level treatment facility or the backflow breeding pond. When the quartz sand filtration effect in the stone barrel body 1 decreases due to excessive dirt, the air pump can be used to filter the water. The pneumatic quartz sand backwashing device performs backwashing. First, the backwashing cover 35 is closed. The quartz sand backwashing pipe 31 is fixed to the center of the bottom of the barrel body 1 by the quartz sand backwashing pipe fixing base 32. The pneumatic pipe 33 of the external air pump raises the liquid level in the quartz sand backwashing pipe 31 through a large number of bubbles and drives the mixture of quartz sand and dirt at the bottom of the pipe to move upward in the pipe and gush out. After being screened by the dirt screening double-layer baffle 34, the quartz sand has a large gravity and cannot pass through the dirt screening double-layer baffle 34 and fall back into the barrel. The dirt is discharged through the sewage pipe 36 along with the water flow.

[0031] In addition, the bottom water inlet pipe, including four water inlet pipes 21, 22, 23, and 24 with valves located at the bottom of the barrel body, can control the water inlet source by opening and closing valves on different pipes or controlling the valve opening amplitude to meet the needs of suspending filtration of some water sources or adjusting the amount of filtered water.

[0032] In addition, the aerodynamic oxygenation water outlet pipe includes four water outlet pipes 41, 42, 43, and 44 located on the outer edge of the top of the barrel body with external air pump oxygenation pipes. The water outlet direction can be controlled by opening and closing the oxygenation pipes on different pipes or controlling the oxygenation amount to meet the needs of suspending water outlet or adjusting the water outlet amount at different water outlets.

[0033] In addition, sand filtration systems often produce harmful substances due to the decomposition of organic matter in an oxygen-deficient environment. This equipment effectively reduces the possibility of such risks through multiple oxygen-enhancing air supply pipelines.

[0034] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the utility model, or are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
