Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a filter for industrial sewage treatment. Background Art

[0002] Industrial wastewater includes production wastewater, production wastewater and cooling water, which refers to the wastewater and waste liquid generated in the industrial production process, which contains industrial production materials, intermediate products, by-products and pollutants generated in the production process that are lost with water. Traditional industries will produce a large amount of sewage. If these sewage flows into nature without treatment, it will cause great damage to the natural environment, so it is necessary to take effective treatment measures for industrial sewage. Nowadays, filters are mostly used to remove impurities from industrial sewage. Most existing filters use filter plates to filter impurities in sewage, but in the process of removing impurities, impurities accumulate more and more on the filter plates, and the current treatment method for impurities on the filter plates is relatively cumbersome, mainly including using a scraper and dirt suction plate to remove dirt after the filter plate is disassembled. This cleaning method requires a lot of disassembly, which increases the labor intensity of workers and reduces work efficiency. To this end, we provide a filter for industrial sewage treatment to solve the above problems. Utility Model Content

A group of cleaning rods are provided.

[0004] Preferably, a perforated plate is provided in the inner cavity of the shell above the first filter plate, the perforated plate is rotatably connected to the rotating shaft, a water inlet pipe is penetrated through the top opening of the shell, and a drain valve is penetrated through the bottom of the side wall of the shell.

[0014] 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.

[0015] The utility model proposes a filter for industrial sewage treatment, comprising a shell 1, an inner cavity of the shell 1 is horizontally provided with a first filter plate 2 and a second filter plate 3 from top to bottom, the pore size of the first filter plate 2 is larger than that of the second filter plate 3, so that the sewage can be double filtered, the outer wall of the shell 1 is located at the upper surface of the first filter plate 2 and the second filter plate 3, and a sewage pipe 6 is penetrated and arranged, and a control valve 7 is installed on the sewage pipe 6. After the control valve 7 is opened, impurities can be discharged through the sewage pipe 6, and a rotating shaft 10 is rotatably arranged at the top of the shell 1, and the outer wall of the rotating shaft 10 is rotatably connected with the first filter plate 2 and the second filter plate 3 respectively. The rotation of the rotating shaft 10 is preferably connected by a sealed bearing, and the outer wall of the rotating shaft 10 is located at the upper surface of the first filter plate 2 and the second filter plate 3. A group of cleaning rods 11 are arranged, and when the rotating shaft 10 rotates, the cleaning rods 11 can be driven to drive the impurities on the top of the first filter plate 2 or the second filter plate 3 to gather and centrifuge, so that the impurities can be moved to the sewage pipe 6 for discharge.

[0016] Specifically, the inner cavity of the shell 1 is located above the first filter plate 2 and is provided with a perforated plate 14, which is rotatably connected to the rotating shaft 10 so that the sewage can fall evenly through the holes inside the perforated plate 14, and a water inlet pipe 4 is penetrated at the top opening of the shell 1, which can be connected to an external water pipe and introduce sewage into the inner cavity of the shell 1, and a drain valve 5 is penetrated at the bottom of the side wall of the shell 1, and the design of the drain valve 5 can discharge the water after impurities are removed.

[0017] Specifically, the cleaning rods 11 are arranged in an arc shape, and each group of cleaning rods 11 is arranged in a ring array with the rotating shaft 10 as the center. The design purpose is to facilitate the collection and removal of impurities to the outside.

[0018] Specifically, a brush rod 12 is provided on the inner arc surface of the cleaning rod 11, and the bristles of the brush rod 12 are in contact with the corresponding first filter plate 2 or the second filter plate 3. The rotating brush rod 12 can scrape and separate impurities adhered to the top of the first filter plate 2 or the second filter plate 3, thereby cleaning the impurities on the top of the first filter plate 2 and the second filter plate 3 more thoroughly.

[0019] Specifically, the sewage port of the sewage pipe 6 is threadedly connected to the collecting cylinder 13, and an observation window is installed at the opening of the side wall of the collecting cylinder 13. When a certain amount of impurities in the collecting cylinder 13 are collected, the collecting cylinder 13 can be unscrewed to take out the impurities.

[0020] Specifically, a motor 8 and a reducer 9 are installed on the top of the shell 1. The output end of the motor 8 is fixedly connected to the input end of the reducer 9, and the output end of the reducer 9 is fixedly connected to the top of the rotating shaft 10. The operation of the motor 8 can reduce the output speed through the reducer 9 and drive the rotating shaft 10, the cleaning rod 11 and the brush rod 12 to rotate.

[0021] According to the personnel in this field, all the electrical parts and components in this case are universal standard parts or components known to the technical personnel in this field, and their structures and principles can be known to the technical personnel through technical manuals or through conventional experimental methods. The models are compatible with this solution and can operate normally. All the electrical parts in this case are connected to the power supply adapted to them through wires, and according to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection is completed in the working order of each electrical component. The detailed connection means are well-known technologies in this field and will not be explained in the electrical control.

[0022] Working principle: When using the filter, the sewage can be injected into the housing 1 through the pipeline connected to the water inlet pipe 4, and the sewage can fall evenly through the holes inside the orifice plate 14, so that the sewage can evenly filter large particles of impurities on the first filter plate 2, and fall to the second filter plate 3 to filter small particles of impurities. The sewage after double-layer filtration can continue to fall and be discharged at the drain valve 5. At this time, the control valve 7 can be opened and the motor 8 can be started. Under the operation of the motor 8, the output speed is reduced through the reducer 9, and the shaft 10, the cleaning rod 11 and the brush rod 12 are driven to rotate. The rotating cleaning rod 11 can use centrifugal force to The impurities on the top of the first filter plate 2 or the second filter plate 3 are centrifuged, so that the impurities can move away from the rotating shaft 10 and enter the interior of the sewage pipe 6, and are collected in the collecting cylinder 13. At the same time, the rotating brush rod 12 can scrape and separate the impurities adhered to the top of the first filter plate 2 or the second filter plate 3, so that the impurities on the top of the first filter plate 2 and the second filter plate 3 can be cleaned more thoroughly. When a certain amount of impurities in the collecting cylinder 13 is collected, the collecting cylinder 13 can be screwed down to take out the impurities, so that the filter does not need to disassemble the first filter plate 2 and the second filter plate 3, saving a lot of disassembly time.
