Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a debris cleaning device for wastewater treatment. Background Technology
[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Currently, wastewater treatment often involves using filters to intercept and remove larger impurities, while finer impurities are removed through denser filters. However, this method is prone to clogging due to the dense mesh size of the filters, requiring regular cleaning or replacement to maintain efficiency. To further improve efficiency, workers often add flocculants to aggregate fine impurities for easier removal. This process also requires mixing the wastewater and flocculant before removal. During mixing, aggregated impurities tend to adhere to the mixing blades, necessitating regular cleaning. Furthermore, using flocculants requires different equipment to effectively aggregate and remove fine impurities, leading to reduced overall wastewater treatment efficiency. Utility Model Content
[0003] In order to overcome the shortcomings mentioned in the background art, the present invention provides a debris cleaning device for sewage treatment.
[0004] The technical solution of this utility model is as follows: a wastewater treatment debris cleaning device, comprising a housing, a symmetrically distributed bracket fixed to the bottom of the housing, a rotating shaft rotatably connected to the top of the housing, a transmission gear fixed to the end of the rotating shaft, a servo motor mounted on one side wall of the housing, a spur gear meshing with the transmission gear mounted on the output shaft of the servo motor, a filter screen fixed to the rotating shaft, a three-way pipe connected to the bottom of the housing, an electromagnetic ball valve mounted on the three-way pipe, a sliding groove opened on one side of the top of the housing, a collection frame slidably connected in the sliding groove, an electric push rod mounted on the other side wall of the housing, a connecting frame fixed to the telescopic end of the electric push rod, the connecting frame rotatably connected to the collection frame, a guide groove opened on the side wall of the sliding groove, a guide ball fixed to the side wall of the collection frame, the guide ball slidingly located in the corresponding guide groove.
[0005] Preferably, one side of the collection frame is open to facilitate the discharge of debris that falls onto it.
[0006] Preferably, the outer surface of the filter screen is slidably fitted against the inner wall of the housing.
[0007] Preferably, a holding groove is provided on one side of the top of the collection frame, and a shaft is rotatably connected in the holding groove. The shaft coincides with the center line of the guide ball, and the shaft is rotatably connected to the connecting frame.
[0008] Preferably, the top of the collection frame and the bottom of the filter screen are both fixed with staggered collision blocks.
[0009] Preferably, the collision block is made of an elastic, deformable material.
[0010] Preferably, a fixing plate is fixedly connected to one side wall of the bracket, a sliding rod is slidably connected to the fixing plate, a contact block is fixedly connected to the upper end of the sliding rod, a connecting plate is fixedly connected to the lower end of the sliding rod, a spring is fixedly connected between the connecting plate and the fixing plate, and the spring is wound around the outside of the sliding rod.
[0011] Preferably, the top of the housing is fixedly connected to symmetrically distributed mounting brackets, and rotating rods are rotatably connected between the symmetrically distributed mounting brackets. A cleaning brush is fixedly connected to the rotating rod, and a connecting gear is fixedly connected to the end of the rotating rod. A spur rack that meshes with the connecting gear is fixedly connected to the top of the collection frame.
[0012] Beneficial Effects: This invention utilizes a servo motor to rotate the filter screen 120° clockwise and counterclockwise, accelerating the mixing of flocculant and wastewater. The flocculant adsorbs fine impurities in the wastewater, increasing their volume for easier removal. The clockwise and counterclockwise rotation of the filter screen prevents debris from adhering to it, eliminating the need for regular cleaning and improving the efficiency of debris removal after wastewater treatment. Once the filter screen is parallel to the collection frame during clockwise rotation, the servo motor is turned off, and the electric push rod is activated to gradually move the collection frame out of the chute. The moving collision blocks on the collection frame collide with the collision blocks on the filter screen, generating vibration that shakes off the debris and onto the collection screen. Inside the frame, the cleaning brush rotates counterclockwise to sweep away debris on the collection frame, preventing debris from adhering to it and affecting discharge. This also prevents debris from accumulating in the collection frame and affecting subsequent debris collection. Workers need to clean the debris accumulated in the collection frame, further improving the efficiency of debris cleaning. When the collection frame moves out of the chute and away from the filter screen, because the connection between the connecting frame and the collection frame is hinged, the right side of the collection frame will swing downward. During this process, the movement of the collection frame can be guided and limited by the cooperation of the guide ball and the guide groove. The elasticity of the spring causes the connecting plate to move upward a certain distance. This allows the contact block to push the right side of the collection frame upward through the slide rod, thus allowing the collection frame to swing up and down, causing the impurities on it to slide off to the right and be discharged.

Detailed Implementation
[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.
[0022] A wastewater treatment debris removal device, such as Figure 1-7As shown, the device includes a housing 1. Supports 2 are fixedly attached to the left and right sides of the bottom of the housing 1. A rotating shaft 3 is rotatably connected to the center of the top of the housing 1. A transmission gear 4 is fixedly attached to the front end of the rotating shaft 3. A servo motor 5 is mounted on the front side wall of the housing 1 via a mounting base. A spur gear 6, meshing with the transmission gear 4, is mounted on the output shaft of the servo motor 5. A filter screen 7 is fixedly attached to the rotating shaft 3. The outer surface of the filter screen 7 slides against the inner wall of the housing 1. A three-way pipe 8 connects to the bottom of the housing 1. An electromagnetic ball valve 9 is installed on the three-way pipe 8. A groove 10 is opened on the right side of the top of the housing 1, and a [missing information - likely a device name] is slidably connected within the groove 10. The collection frame 11 has an open right side to facilitate the discharge of debris that falls on it. An electric push rod 12 is installed on the rear side wall of the housing 1. A connecting frame 13 is fixedly connected to the telescopic end of the electric push rod 12. A guide groove 14 is opened on the side wall of the slide 10. A guide ball 15 is fixedly connected to the side wall of the collection frame 11. The guide ball 15 slides in the corresponding guide groove 14. A holding groove 111 is opened on the rear side of the top of the collection frame 11. A shaft 112 is rotatably connected in the holding groove 111. The center line of the shaft 112 coincides with that of the guide ball 15, and the shaft 112 is rotatably connected to the connecting frame 13.
[0023] Both the top of the collection box 11 and the bottom of the filter screen 7 are fixed with staggered collision blocks 16, which are made of elastic and deformable material.
[0024] A fixing plate 17 is fixedly connected to the right side wall of the bracket 2 on the right side. A slide rod 18 is slidably connected to the fixing plate 17. A contact block 19 is fixedly connected to the upper end of the slide rod 18. A connecting plate 20 is fixedly connected to the lower end of the slide rod 18. A spring 21 is fixedly connected between the connecting plate 20 and the fixing plate 17, and the spring 21 is wrapped around the outside of the slide rod 18.
[0025] Two mounting brackets 22 are fixedly attached to the right side of the top of the housing 1, which are symmetrically distributed front and back. A rotating rod 23 is rotatably connected between the two mounting brackets 22. A cleaning brush 24 is fixedly attached to the rotating rod 23. A connecting gear 25 (a one-way gear) is fixedly attached to the end of the rotating rod 23. A spur rack 26 that meshes with the connecting gear 25 is fixedly attached to the top of the collection frame 11.
[0026] Initially, the filter screen 7 is vertical and located inside the housing 1. During use, the user feeds the wastewater to be treated into the housing 1 via an external device and adds an appropriate amount of flocculant. The user then starts the servo motor 5, which drives the transmission gear 4 to rotate 120° clockwise and counterclockwise via the spur gear 6. The transmission gear 4 rotates the filter screen 7 via the shaft 3. This 120° clockwise and counterclockwise rotation of the filter screen 7 accelerates the mixing of the flocculant and wastewater. This allows the flocculant to adsorb fine impurities in the wastewater, increasing their volume for easier removal. After the impurities in the wastewater have coagulated, during the clockwise and counterclockwise rotation of the filter screen 7 (hereinafter referred to as clockwise and counterclockwise rotation), the filter screen 7 can... The filter screen 7 can intercept debris moving in a clockwise direction, while wastewater passes through it and carries away debris adhering to its right side. During counter-clockwise rotation, the filter screen 7 can also intercept debris moving in a counter-clockwise direction, while wastewater passes through it and carries away debris adhering to its left side. Therefore, the filter screen 7 only intercepts debris on one side during both rotations, leaving the other side untouched. This rotation of the filter screen 7, which mixes wastewater and flocculant, prevents debris from adhering to it, avoiding the need for regular cleaning and improving the efficiency of debris removal after wastewater treatment. The user then uses a servo motor 5 to drive the filter screen 7 to rotate 360°. During this process, the user activates the electric push rod 12 to move the collection frame 11 into the chute 10 via the connecting frame 13. After the collection frame 11 is located in the upper part of the housing 1, the electric push rod 12 is turned off. Therefore, when the filter screen 7 rotates clockwise and becomes parallel to the collection frame 11, the servo motor 5 is turned off and the electric push rod 12 is activated to gradually move the collection frame 11 out of the chute 10 (the interval between the servo motor 5 turning off and activating is 5-60 seconds). During this process, the collision block 16 on the collection frame 11 moves and collides with the collision block 16 on the filter screen 7, generating vibration. This vibration causes the filter screen 7 to shake off the debris it has collected and fall into the collection frame 11. As the collection frame 11 moves out of the chute 10, the collection frame 11... The drive mechanism, via the rack and pinion 26 and gear 25, rotates the rod 23, causing the cleaning brush 24 to rotate counterclockwise. This counterclockwise rotation of the cleaning brush 24 sweeps away debris from the collection frame 11, preventing it from adhering and affecting discharge. It also prevents debris buildup in the collection frame 11, thus avoiding the need for workers to clean it, further improving cleaning efficiency. Simultaneously, when the collection frame 11 moves out of the chute 10 and away from the filter screen 7, because the connection between the connecting frame 13 and the collection frame 11 is hinged, the right side of the collection frame 11 will swing downwards. During this process, the guide ball 15 and guide groove 14 guide and limit the movement of the collection frame 11.During the downward tilting of the right side of the collection frame 11, the contact block 19 will be squeezed first, causing it to move downward. The downward movement of the contact block 19, via the slide rod 18, causes the connecting plate 20 to move downward, stretching the spring 21. Under the elastic action of the spring 21, the connecting plate 20 can move up and down repeatedly for a period of time until it reaches a stationary state. Therefore, the slide rod 18 can be used to push the right side of the collection frame 11 up and down repeatedly, using the cleaning brush 24 to sweep away debris inside the collection frame 11, preventing debris from adhering to the collection frame 11. Simultaneously, the up-and-down shaking of the collection frame 11 causes impurities on it to quickly slide to the right and be discharged. When the collection frame 11 moves out of the slide groove 10 and away from the filter screen 7, the servo motor 5 operates, causing the filter screen 7 to continue rotating clockwise to retrieve debris from the housing 1. After cleaning the debris after wastewater treatment, the user can open the three-way pipe 8 through the solenoid ball valve 9 to discharge the treated wastewater. The solenoid ball valve 9 can be closed to shut off the three-way pipe 8 at any time.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
