Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment equipment technology, and in particular to a device for cleaning solid pollutants in wastewater. Background Technology

[0002] Wastewater typically refers to water bodies containing various pollutants and harmful substances, including domestic sewage and industrial wastewater. In order to reduce the impact of wastewater on the natural environment, it is necessary to use cleaning devices to remove pollutants from the wastewater.

[0003] Solid pollutants in wastewater mainly include suspended solids, colloidal impurities, and dissolved impurities. These pollutants exist in water primarily in three states: suspended, colloidal, and dissolved. Therefore, treating solid pollutants in wastewater is one of the main processes in wastewater treatment. Traditional cleaning equipment primarily uses filtration to treat solid pollutants in wastewater. For example, utility model patent CN221014717U discloses a wastewater solid pollutant interception device. This device uses a detachable filter screen to intercept solid pollutants in wastewater. When the operator cleans the pollutants fixed at the front end of the filter screen, the operator controls a dual-axis motor to rotate, thereby driving the first and second bidirectional screws to rotate. This brings the two moving components closer together, scraping off the solid pollutants at the front end of the filter screen, making it easier for the operator to remove the pollutants. However, although the above-mentioned device can periodically clean the debris on the surface of the filter plate, the debris remains on the filter plate during the process of filtering sewage. As the amount of impurities retained on the filter plate gradually increases, they will block the mesh of the filter plate, thereby affecting the flow of water through the filter plate and reducing the cleaning effect of debris in sewage.

[0004] Based on this, the present invention provides a device for cleaning solid pollutants in sewage to solve the problems existing in the prior art. Utility Model Content

[0005] In view of this, the main objective of this utility model is to provide a wastewater solid pollutant cleaning device to solve the problem that when the impurities retained on the filter plate of a traditional interception device gradually increase, they affect the flow of water through the filter plate, resulting in a reduction in the cleaning effect of impurities in wastewater.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0007] A device for cleaning solid pollutants in wastewater, comprising:

[0008] Cleaning box;

[0009] Cleanup agencies, including:

[0010] The fixed frame is slidably installed inside the cleaning box and contacts the inner wall of the cleaning box;

[0011] Filter plates are evenly arranged on a fixed frame;

[0012] The rotating rod is mounted on the upper part of the cleaning box, and a guide plate is provided at the lower end of the rotating rod.

[0013] In a preferred embodiment, the filter plate has a V-shaped structure, and the opposite sides of two adjacent filter plates are fixedly connected.

[0014] In a preferred embodiment, the center of the rotating rod and the center point of the fixed frame are on the same vertical plane.

[0015] In a preferred embodiment, the cleaning mechanism further includes collection frames disposed on both sides inside the cleaning box, the bottom of the collection frames forming an angle with the horizontal plane, and a filter screen embedded at the bottom of the collection frames.

[0016] In a preferred embodiment, a baffle is provided on one side of the inner wall of the collection frame, and the baffle is inclined.

[0017] In a preferred embodiment, sliding plates are slidably connected to both sides of the inner wall of the cleaning box, and a spring is provided between the bottom end of the sliding plate and the cleaning box. The other side of the sliding plate extends through the cleaning box and is connected to the bottom end of the fixing frame.

[0018] In a preferred embodiment, a servo motor is provided on the cleaning box, and one end of the rotating rod extends through the cleaning box and is connected to the servo motor.

[0019] In a preferred embodiment, the filter plate is further provided with a fixing rod, the surface of which is arc-shaped.

[0020] In a preferred embodiment, a protective plate is symmetrically arranged at the top center of the fixed frame, and the protective plate is located above the filter plate.

[0021] In a preferred embodiment, the guide plate has multiple evenly distributed grooves on both sides.

[0022] Compared with the prior art, this utility model provides a device for cleaning solid pollutants in sewage, which has the following beneficial effects:

[0023] 1. Through the design of the cleaning mechanism, during use, the cleaning mechanism separates dirt from sewage using two sets of inclined filter plates, ensuring the cleaning effect of dirt in sewage. At the same time, the action of water flow and the inclined installation of filter plates facilitates the flow of dirt on the filter plates towards the collection frame, and the specific shape of the filter plates enhances the downward flow of debris. During the reciprocating rotation of the guide plate, it helps to guide the water flow above the filter plates, making the water flow path gradually inclined during the rotation of the guide plate, so that the debris on the filter plates can move better towards the collection frame and be collected by the collection frame, thus avoiding the retention of intercepted debris on the filter plates, ensuring the flow of water during the filtration process, and thus enhancing the cleaning effect of dirt in the water flow.

[0024] 2. Under the action of the spring and the constantly changing water pressure passing through multiple filter plates, the fixed frame drives the multiple filter plates to continuously move up and down as they intercept impurities in the sewage. This allows the impurities on the filter plates to move more effectively towards the collection frame, enhancing the cleaning effect on the filter plate surface. This solves the problem of traditional interception devices where the increasing amount of impurities retained on the filter plates affects the flow of water through the filter plates, leading to a decrease in the cleaning effect on impurities in the sewage.

[0042] As per the instruction manual Figures 1-6 As shown, this utility model provides a technical solution:

[0043] A wastewater solid pollutant cleaning device includes: a cleaning box 1 and a cleaning mechanism 2 disposed on the cleaning box 1. The cleaning mechanism 2 includes a fixed frame 21 slidably connected inside the cleaning box 1. The fixed frame 21 forms an isosceles triangle with the horizontal plane. Multiple uniformly distributed filter plates 22 are fixedly connected to both sides of the inner wall of the fixed frame 21. The overall shape of the filter plates 22 is "V". The opposite sides of two adjacent filter plates 22 are fixedly connected. A rotating rod 23 is rotatably connected to the upper end of the inner wall of the cleaning box 1. A guide plate 24 is fixedly connected to the lower end of the surface of the rotating rod 23. The center of the rotating rod 23 and the center point of the fixed frame 21 are on the same vertical plane.

[0044] It should be noted that in this embodiment, the multiple filter plates 22 on one side of the inner wall of the fixed frame 21 are a group, and the two groups of filter plates 22 are symmetrically arranged at the center point of the fixed frame 21. A water inlet pipe 3 is connected to the top center of the cleaning box 1, and a water outlet pipe 4 is connected to the bottom end of the cleaning box 1. When filtering sewage, the sewage enters from the water inlet pipe 3 at the top of the cleaning box 1 and the cleaning mechanism 2 intercepts and cleans the dirt in the sewage. The separated water flows out from the bottom end of the cleaning box 1 through the water outlet pipe 4.

[0045] In a preferred embodiment, such as Figure 2 and Figure 3 As shown, the cleaning mechanism 2 also includes two collection frames 25 that are fixedly connected to the inner walls of the lower end of the cleaning box 1. The bottom of the collection frame 25 forms an angle with the horizontal plane, and a filter screen 26 is embedded in the bottom of the collection frame 25.

[0046] It should be noted that in this embodiment, the ends of the two sets of filter plates 22 that are far apart from each other are located above the two collection frames 25. When dirt falls from the filter plates 22, it will enter the collection frames 25. Sealing plates are installed on both sides of the cleaning box 1. When cleaning the dirt collected in the collection frames 25, the sealing plates 214 can be opened.

[0047] In a preferred embodiment, such as Figure 3 , Figure 4 and Figure 6 As shown, sliding plates 27 are slidably connected to both sides of the inner wall of the cleaning box 1. A spring 28 is fixedly connected between the bottom end of the sliding plate 27 and the inner wall of the cleaning box 1. The other side of the sliding plate 27 extends through the cleaning box 1 and is fixedly connected to the bottom end of the fixing frame 21.

[0048] It should be noted that in this embodiment, grooves 11 matching the slide plate 27 are provided on both sides of the inner wall of the cleaning box 1. The spring 28 is set in the groove 11. When sewage enters the cleaning box 1 and is rotated back and forth by the guide plate 24, the water pressure passing through the multiple filter plates 22 will change continuously. Therefore, under the action of the spring 28, the fixed frame 21 will continuously move up and down when it drives the multiple filter plates 22 to intercept the dirt in the sewage.

[0049] In a preferred embodiment, such as Figure 4 As shown, a servo motor 213 is fixedly connected to the upper surface of the cleaning box 1, and one end of the rotating rod 23 passes through the cleaning box 1 and is fixedly connected to the output shaft of the servo motor 213.

[0050] It should be noted that in this embodiment, when the device is filtering and cleaning impurities in the sewage, the servo motor 213 is started by the controller to drive the rotating rod 23 to rotate slowly, so that the rotating rod 23 rotates 20 degrees clockwise and 20 degrees counterclockwise. This causes the rotating rod 23 to drive the guide plate 24 to reciprocate between 20 degrees clockwise and 20 degrees counterclockwise. It should be noted that the reciprocating rotation effect is best within this set angle. The specific reciprocating rotation angle can be set according to the actual situation.

[0051] In a preferred embodiment, such as Figure 6 As shown, a fixing rod 29 is fixedly connected to the surface of the filter plate 22, and the surface of the fixing rod 29 is bent into an arc shape.

[0052] It should be noted that in this embodiment, the center point of the fixing rod 29 coincides with the center point of the filter plate 22. When the filter plate 22 intercepts pollutants in the sewage, the fixing rod 29 increases the gap between the pollutants on the filter plate 22 and the filter plate 22, so that the pollutants can be filtered more effectively.

[0053] In a preferred embodiment, such as Figure 6 As shown, a protective plate 210 is also fixedly connected to the top center of the fixed frame 21, and the protective plate 210 forms an isosceles triangle with the horizontal plane.

[0054] It should be noted that in this embodiment, the protective plate 210 is placed above the opposite ends of the two sets of filter plates 22, thereby continuing to guide the water flow above the opposite ends of the two sets of filter plates 22, ensuring that the downward flowing sewage is fully filtered by the filter plates 22.

[0055] In a preferred embodiment, such as Figure 4 As shown, a baffle 211 is fixedly connected to one side of the inner wall of the collection frame 25, and the baffle 211 is inclined.

[0056] It should be noted that in this embodiment, the tilt angle of the baffle 211 is opposite to the tilt direction of the bottom of the collection frame 25. Therefore, when the collection frame 25 collects the intercepted debris, the baffle 211 will block the dirt in the collection frame 25, preventing it from falling directly onto the filter screen 26 on the lower side of the collection frame 25 and clogging the filter screen 26.

[0057] In a preferred embodiment, such as Figure 4 As shown, multiple evenly distributed grooves 212 are provided on both sides of the guide plate 24 to better guide the water flow on the surface of the guide plate 24 through the grooves 212.

[0058] When the wastewater solid pollutant cleaning device of this utility model is in use: wastewater enters from the inlet pipe 3 at the top of the cleaning tank 1. At this time, the guide plate 24 diverts the wastewater entering the cleaning tank 1, and the two sets of filter plates 22 intercept the dirt in the wastewater. The separated water flows out from the bottom of the cleaning tank 1. At this time, the debris retained on the filter plates 22 will flow towards the collection frame 25 under the action of water flow and the inclined installation of the filter plates 22. At the same time, the servo motor 213 is started by the controller, so that the servo motor 213 drives the rotating rod 23 to drive the guide plate 24 to reciprocate. During the reciprocating rotation of the guide plate 24, the water flowing above the filter plates 22 is guided, so that the water flow path is... As the guide plate 24 rotates, the water flow path gradually tilts, causing debris on the filter plate 22 to move towards the collection frame 25. This allows the debris to enter the collection frame 25, while the water flowing into the collection frame 25 flows out through the filter screen 26. Simultaneously, the reciprocating rotation of the guide plate 24 causes the water pressure passing through the multiple filter plates 22 to change continuously. Therefore, under the action of the spring 28, the fixed frame 21 drives the multiple filter plates 22 to continuously move up and down to intercept the dirt in the sewage. This allows the debris on the filter plates 22 to move better towards the collection frame 25, preventing dirt from remaining on the filter plates 22 and affecting the filtration efficiency of the filter plates 22.

[0059] It should be noted that the servo motor 213 mentioned above is a device with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the servo motor 213 can be powered by the built-in power supply or by AC power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0060] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
