Description

Technical Field

[0001] The utility model relates to the technical field of solid waste filtration for sewage treatment, in particular to a solid waste filtration device for sewage treatment. Background Technique

[0002] Sewage treatment refers to the process of purifying sewage to meet the water quality requirements for discharging into a certain water body or reusing it. Before sewage filtration, there will be solid waste in the sewage, which affects the quality of subsequent sewage filtration. Therefore, it is necessary to remove the solid waste in the sewage, and a solid waste filtration device for sewage treatment is required.

[0003] For example, a solid waste filtration device for sewage treatment with the publication number of "CN220294281U" is simple to use. Sewage can be poured into multiple rotating cylinders. When the motor is started, it can drive the rotating cylinders to rotate and throw out the water in the solid waste in the rotating cylinders for solid-liquid separation. The filter plate plays a role in filtering water and sewage. The pressing plate can squeeze out the water in the solid waste in the sewage in the rotating cylinders through the pulling force of the tension spring. And the first scraper and the second scraper are arranged on the rotating cylinder to clean the stains in the installation cylinder. However, in the above, the staff needs to manually lift the moving rod to take out the solid waste on the pressing plate. Since there are many bacteria in the solid waste, close contact is likely to cause harm to the staff's body. And the size of the rectangular holes arranged on the rotating cylinder is fixed, and only solid waste of a fixed size can be filtered, thus reducing the quality of subsequent sewage filtration. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems that because there are many bacteria in the solid waste, close contact is likely to cause harm to the staff's body, and the size of the rectangular holes arranged on the rotating cylinder is fixed, and only solid waste of a fixed size can be filtered, thus reducing the quality of subsequent sewage filtration, and to provide a solid waste filtration device for sewage treatment.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] Design a solid waste filtration device for sewage treatment, including a bottom plate and a vertical plate. The upper left side of the outer wall of the bottom plate is fixedly connected to the vertical plate. The outer wall of the vertical plate is fixedly connected with a first box body. A solid waste discharging structure for sewage treatment is arranged on the outer wall of the first box body. The upper right side of the outer wall of the bottom plate is fixedly connected with a tank body through a bracket. A solid waste filtering structure for sewage treatment is arranged on the right side of the outer wall of the tank body. A feed inlet is arranged on the upper left side of the tank body, and a discharge outlet is arranged on the lower right side of the tank body. A material box is placed in the middle of the upper end of the outer wall of the bottom plate.

[0007] Preferably, the solid waste discharging structure for sewage treatment includes a first motor, and the end of the output shaft of the first motor is fixedly connected with a first gear. The rotating shaft of the first gear is rotatably connected to a first box body through a bearing. The outer wall of the first gear is meshed with a second gear, and the outer walls of the first gear and the second gear are meshed with a rack.

[0008] Preferably, the outer wall of the first motor is fixedly connected with the first box body through a bracket, and the rotating shaft of the second gear is rotatably connected to the first box body through a bearing.

[0009] Preferably, the outer walls of the two racks are slidably connected with the first box body, and the tank cover is hermetically connected to the left end of the outer wall of the tank body.

[0010] Preferably, the solid waste filtering structure for sewage treatment includes a second box body. The right side of the outer wall of the second box body is fixedly connected with a second motor through a bracket. The end of the output shaft of the second motor is fixedly connected with a threaded rod. The outer wall of the threaded rod is threadedly connected with a threaded seat. The outer wall of the threaded seat is slidably connected with the second box body. The outer wall of the threaded seat is fixedly connected with a cross bar. The left end of the outer wall of the cross bar is fixedly connected with a frame, and filter meshes are installed at both ends of the inner wall of the frame.

[0011] Preferably, the left side of the outer wall of the second box body is fixedly connected with the tank body, and the outer wall of the cross bar is slidably connected with the tank body.

[0012] For a solid waste filtering device for sewage treatment proposed by the present utility model, the beneficial effects are as follows: Through the cooperation of the solid waste filtering structure for sewage treatment and the tank body, the solid waste in the sewage will be filtered through two filter meshes with different through-hole densities, and the sewage will flow to the right end of the tank body. The second motor is started to drive the threaded rod to rotate in the second box body through a bearing. The rotation of the threaded rod drives the threaded seat to slide leftward in the chute machined on the inner wall of the second box body. The leftward sliding of the threaded seat drives the cross bar to slide leftward in the tank body. In this way, the cross bar drives the frame and the two filter meshes to move leftward to contact the top cover to extrude the solid waste. In this way, the moisture in the larger solid waste can be reduced. The two filter meshes with different through-hole densities can intercept solid waste of different sizes in the sewage, improving the quality of subsequent sewage treatment.

The rotation of the first gear drives the second gear to rotate in the first box body through a bearing. The first gear and the second gear rotate towards each other and respectively drive the racks to slide leftward in the chute machined on the inner wall of the first box body. The leftward sliding of the two racks drives the tank cover to move leftward to separate it from the tank body. After the tank cover is opened, the frame and the filter mesh are used to push the solid waste into the material box, eliminating the need for manual operation by workers and avoiding the harm that can easily be caused to the workers' bodies by close contact.

[0028] Working principle:

[0029] Solid waste filtering work for sewage treatment:

[0030] When it is necessary to filter the solid waste in the sewage, the sewage with solid waste is introduced into the tank body 3 from the feed port 5. At this time, the solid waste in the sewage will be filtered through two filters 207 with different through-hole densities, and the sewage will flow to the right end of the tank body 3 (the two filters 207 with different through-hole densities can intercept solid waste of different sizes in the sewage). Subsequently, the discharge port 6 is connected to the sewage filtration equipment through an external pipeline, and the valve installed in the middle of the discharge port 6 is opened. At this time, the sewage inside the tank body 3 will flow out from the discharge port 6, and at the same time, the solid waste will be blocked by the two filters 207. After the sewage inside the tank body 3 is filtered and flows out, the external power supply of the second motor 202 is connected, and the second motor 202 starts to drive the threaded rod 203 to rotate in the second box body 201 through the bearing. The rotation of the threaded rod 203 drives the threaded seat 204 to slide leftward in the chute machined on the inner wall of the second box body 201. The leftward sliding of the threaded seat 204 drives the cross bar 205 to slide leftward in the tank body 3. In this way, the frame 206 and the two filters 207 are driven by the cross bar 205 to move leftward to contact the top cover 105 to squeeze the solid waste. In this way, the moisture in the larger solid waste can be reduced. The solid waste in the middle of the frame 206 is smaller and has a lower water storage capacity and does not need to be squeezed. In this way, part of the water in the solid waste can be pressed out and utilized for later collection.

[0031] Solid waste collection work:

[0032] After squeezing the larger solid waste, the external power supply of the first motor 101 is connected, and the first motor 101 starts to drive the first gear 102 to rotate in the first box body 9 through the bearing. The rotation of the first gear 102 drives the second gear 103 to rotate in the first box body 9 through the bearing. The first gear 102 and the second gear 103 rotate in opposite directions and respectively drive the rack 104 to slide leftward in the chute machined on the inner wall of the first box body 9. The leftward sliding of the two racks 104 drives the tank cover 105 to move leftward to make it away from the tank body 3. Subsequently, the second motor 202 is controlled to drive the frame 206 to move leftward in the tank body 3. The leftward movement of the frame 206 pushes the larger solid waste into the feed box 8. When the middle part of the frame 206 moves above the feed box 8, the smaller solid waste in the middle part will fall into the feed box 8. In this way, the filtered solid waste can be collected. When it is necessary to filter the solid waste in the subsequent sewage, the second motor 202 is controlled to reverse to drive the frame 206 to reset. Subsequently, the first motor 101 is controlled to reverse to drive the end cover 105 to reset and cover the left end of the tank body 3 again. A sealing ring and a sealing plug are fixed inside the tank cover 105 to ensure the sealing performance at the connection between the tank cover 105 and the tank body 3. Then, the valve in the middle of the discharge port 6 is closed, and then the subsequent sewage solid waste filtration work can be carried out in the same movement mode as above.

[0033] Although the present utility model has been illustrated and described by referring to the preferred embodiments, those of ordinary skill in the art should understand that various changes in form and details can be made within the scope of the claims.
