Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment equipment, specifically a solid-liquid separation device. Background Technology

[0002] Of all water pollution caused by human activities, industrial pollution is the most severe. Industrial wastewater, for example, contains numerous pollutants and has a complex composition, making it difficult to purify and treat. Industrial wastewater is the most significant cause of water pollution from industry, accounting for the majority of pollutants discharged from industrial sources.

[0003] Industrial wastewater typically contains a large amount of solid waste, which needs to be separated before wastewater treatment. Current separation devices mostly rely on filters, which are prone to clogging during separation, leading to inconvenience in subsequent separation processes and reducing the practicality of the device. Therefore, a solid-liquid separation device is proposed to address these issues. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A solid-liquid separation device of this utility model includes a frame, a receiving box fixedly connected to the outside of the frame, a first motor fixedly connected to the outside of the receiving box, a sealing plate fixedly connected to the output end of the first motor, a filter screen fixedly connected to the inner side of the sealing plate, a cylinder fixedly connected to the outside of the receiving box, a push plate fixedly connected to the output end of the cylinder, the push plate and the filter screen working together, and a partition fixedly connected to the outside of the frame, the partition and the filter screen working together. This step, by setting up the first motor, sealing plate, filter screen, cylinder, and push plate, separates wastewater... First, the wastewater is poured into the receiving box, allowing it to pass through the filter screen and drain to one side of the partition. The filter screen traps solid waste. After the wastewater is discharged from the inside of the receiving box, the first motor drives the sealing plate to rotate. The sealing plate then drives the filter screen to rotate until it is parallel and aligned with the push plate. This allows the solid waste to slide down the sealing plate to the other side of the partition, thus achieving separate discharge of solid waste and wastewater. The cylinder drives the push plate to move up and down, and the push plate contacts and collides with the filter screen, shaking off the solid waste adhering to the filter screen. This ensures that the filter screen can be cleaned in time after each separation, preventing the filter screen from becoming clogged and affecting subsequent use, thereby improving the stability of the device.

[0006] Preferably, a baffle is slidably connected to the inner side of the partition, and a movable screw is rotatably connected to the inner side of the baffle. The movable screw is threadedly connected to the partition, and a second motor is fixedly connected to the outer side of the baffle. The output end of the second motor is fixedly connected to the movable screw. This step, by setting up the baffle, movable screw, and second motor, allows the second motor to drive the movable screw to rotate when the sealing plate needs to rotate. The threaded connection between the movable screw and the partition causes the movable screw to move, which in turn drives the baffle and the second motor to move. This allows the baffle to move until it no longer restricts the sealing plate, thus enabling the sealing plate to rotate. When the sealing plate does not need to rotate, the baffle moves to the underside of the sealing plate, further supporting and limiting the sealing plate. This makes the sealing plate more stable in receiving dirt and improves the stability of the device.

[0007] Preferably, the inner side of the partition is provided with a receiving groove, and the outer side of the moving screw is fixedly connected with a limiting plate. The receiving groove and the limiting plate are used in conjunction. By setting the receiving groove and the limiting plate, when the moving screw moves to the maximum position, it is completely inserted into the receiving groove by the limiting plate. The receiving groove restricts the limiting plate, thereby making it difficult for the moving screw to separate from the partition and making it difficult for the baffle to completely detach from the inner side of the partition, thus improving the stability of the device operation.

[0008] Preferably, a protective shell is fixedly connected to the outside of the baffle, and the protective shell is used in conjunction with the second motor. This step, by setting the protective shell, ensures that the second motor is a waterproof motor when sewage is discharged from the filter screen. The protective shell further shields and protects the second motor, making it less likely for sewage to affect the second motor and improving the stability of the device operation.

[0009] Preferably, a sealing ring is fixedly connected to the outer side of the sealing plate, and the sealing ring is used in conjunction with the receiving box. This step, by setting the sealing ring, allows the sealing plate to be retracted into the receiving box, and the sealing ring itself to adhere tightly to the receiving box, thereby further sealing the sealing plate and the receiving box and further improving the sealing performance of the device.

[0010] Preferably, a third motor is fixedly connected to the outside of the frame, and a scraper is fixedly connected to the output end of the third motor. The scraper and the frame are rotatably connected. By setting the third motor and the scraper, after the sealing plate rotates to be perpendicular to the receiving box, the third motor can drive the scraper to rotate downwards. The scraper scrapes off the solid waste adhering to one side of the sealing plate, making the separation of solid waste from the scraper more thorough and improving the stability of the device.

[0011] The advantages of this utility model are:

[0012] 1. This utility model, by setting up a first motor, a sealing plate, a filter screen, a cylinder, and a push plate, first pours sewage into the inside of the receiving box, allowing the sewage to be discharged through the filter screen to one side of the partition. The filter screen intercepts solid waste. After the sewage is discharged from the inside of the receiving box, the first motor drives the sealing plate to rotate, which in turn drives the filter screen to rotate until it is parallel and aligned with the push plate. This allows the solid waste to slide down the sealing plate to the other side of the partition, thus achieving separate discharge of solid waste and sewage. The cylinder drives the push plate to move up and down, and the push plate contacts and collides with the filter screen, shaking off the solid waste adhering to the filter screen. This ensures that the filter screen can be cleaned in time after each separation, preventing the filter screen from becoming clogged and affecting subsequent use, thereby improving the stability of the device.

[0013] 2. This utility model, by setting up a baffle, a moving screw, and a second motor, allows the second motor to drive the moving screw to rotate when the sealing plate needs to rotate. The moving screw is connected to the baffle via a threaded connection, which in turn moves the baffle and the second motor, causing the baffle to move until it no longer restricts the sealing plate, thus allowing the sealing plate to rotate. When the sealing plate does not need to rotate, the baffle moves to the underside of the sealing plate, further supporting and limiting the sealing plate, making the sealing plate more stable in receiving dirt and improving the stability of the device.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Specific implementation examples are given below.

[0024] Please see Figures 1 to 6 As shown, a solid-liquid separation device includes a frame 1, a receiving box 2 fixedly connected to the outside of the frame 1, a first motor 3 fixedly connected to the outside of the receiving box 2, a sealing plate 4 fixedly connected to the output end of the first motor 3, a filter screen 5 fixedly connected to the inside of the sealing plate 4, a cylinder 6 fixedly connected to the outside of the receiving box 2, a push plate 7 fixedly connected to the output end of the cylinder 6, the push plate 7 and the filter screen 5 working together, and a partition plate 8 fixedly connected to the outside of the frame 1, the partition plate 8 and the filter screen 5 working together. This step, by setting up the first motor 3, sealing plate 4, filter screen 5, cylinder 6 and push plate 7, first pours wastewater into the inside of the receiving box 2, so that... Wastewater is discharged through filter screen 5 to one side of partition 8. Solid waste is trapped by filter screen 5. After the wastewater is discharged from the inside of receiving box 2, the first motor 3 drives the sealing plate 4 to rotate. The sealing plate 4 drives the filter screen 5 to rotate until it is parallel and aligned with the push plate 7, so that the solid waste slides down the sealing plate 4 to the other side of partition 8. This achieves the separate discharge of solid waste and wastewater. The cylinder 6 drives the push plate 7 to move up and down. The push plate 7 contacts and collides with the filter screen 5, shaking off the solid waste adhering to the filter screen 5. This ensures that the filter screen 5 can be cleaned in time after each separation, and the filter screen 5 is less likely to become clogged, affecting subsequent use and improving the stability of the device.

[0025] Furthermore, such as Figure 1 , Figure 2 and Figure 6As shown, a baffle 9 is slidably connected to the inner side of the partition 8, and a movable screw 10 is rotatably connected to the inner side of the baffle 9. The movable screw 10 is threadedly connected to the partition 8, and a second motor 11 is fixedly connected to the outer side of the baffle 9. The output end of the second motor 11 is fixedly connected to the movable screw 10. This step, by setting up the baffle 9, the movable screw 10, and the second motor 11, allows the second motor 11 to drive the movable screw 10 to rotate when the sealing plate 4 needs to rotate. The threaded connection between the movable screw 10 and the partition 8 causes the movable screw 10 to move, which in turn drives the baffle 9 and the second motor 11 to move. This allows the baffle 9 to move until it no longer restricts the sealing plate 4, thus enabling the sealing plate 4 to rotate. When the sealing plate 4 does not need to rotate, the baffle 9 moves to the lower side of the sealing plate 4, further supporting and limiting the sealing plate 4. This makes the sealing plate 4 more stable in receiving dirt and improves the stability of the device.

[0026] Furthermore, such as Figure 3 and Figure 6 As shown, a receiving groove 12 is provided on the inner side of the partition 8, and a limiting plate 13 is fixedly connected to the outer side of the moving screw 10. The receiving groove 12 and the limiting plate 13 are used in conjunction. By setting the receiving groove 12 and the limiting plate 13, when the moving screw 10 moves to the maximum position, it completely enters the receiving groove 12 through the limiting plate 13. The receiving groove 12 restricts the limiting plate 13, thereby making it difficult for the moving screw 10 to separate from the partition 8 and making it difficult for the baffle 9 to completely detach from the inner side of the partition 8, thus improving the stability of the device operation.

[0027] Furthermore, such as Figure 2 As shown, a protective shell 14 is fixedly connected to the outside of the baffle 9. The protective shell 14 is used in conjunction with the second motor 11. By setting the protective shell 14, the second motor 11 is a waterproof motor when sewage is discharged from the filter screen 5. The protective shell 14 further shields and protects the second motor 11, making it less likely for sewage to affect the second motor 11 and improving the stability of the device operation.

[0028] Furthermore, such as Figure 1 and Figure 5 As shown, a sealing ring 15 is fixedly connected to the outer side of the sealing plate 4. The sealing ring 15 is used in conjunction with the receiving box 2. This step, by setting the sealing ring 15, allows the sealing plate 4 to be retracted into the receiving box 2. The sealing ring 15 itself is elastic and fits tightly against the receiving box 2, thereby further sealing the sealing plate 4 and the receiving box 2 and further improving the sealing performance of the device.

[0029] Furthermore, such as Figure 3As shown, a third motor 16 is fixedly connected to the outside of the frame 1, and a scraper 17 is fixedly connected to the output end of the third motor 16. The scraper 17 and the frame 1 are rotatably connected. In this step, by setting the third motor 16 and the scraper 17, after the sealing plate 4 is rotated to be perpendicular to the receiving box 2, the third motor 16 can drive the scraper 17 to rotate downward. The scraper 17 scrapes off the solid waste adhering to one side of the sealing plate 4, making the separation of solid waste from the scraper 17 more thorough and improving the stability of the device.

[0030] The working principle is as follows: wastewater is first poured into the inside of the receiving box 2, allowing it to pass through the filter screen 5 and discharge to one side of the partition 8. The filter screen 5 intercepts solid waste. After the wastewater is discharged from the inside of the receiving box 2, the second motor 11 drives the moving screw 10 to rotate. The moving screw 10 is connected to the partition 8 by threads, causing the moving screw 10 to move. The moving screw 10 drives the baffle 9 and the second motor 11 to move, so that the baffle 9 no longer restricts the sealing plate 4. The first motor 3 drives the sealing plate 4 to rotate, which in turn drives the filter screen 5 to rotate until it is parallel and aligned with the push plate 7. This allows solid waste to slide down the sealing plate 4 to the other side of the partition 8, thus achieving separate discharge of solid waste and wastewater. The cylinder 6 drives the push plate 7 to move up and down. The push plate 7 contacts and collides with the filter screen 5, shaking off the solid waste adhering to the filter screen 5. This ensures that the filter screen 5 can be cleaned in time after each separation. Then, the sealing plate 4 is rotated back to its original position, and the moving baffle 9 is aligned with the lower side of the sealing plate 4 to continue providing support.
