Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an automated wastewater treatment tank. Background Technology

[0002] With the acceleration of industrialization and the continuous expansion of urbanization, the amount of wastewater generated is growing rapidly. If wastewater is discharged directly without proper treatment, the large amount of harmful substances it contains, such as heavy metal ions, organic pollutants, and pathogenic microorganisms, will cause serious damage to the aquatic environment, leading to eutrophication of rivers and lakes, as well as polluting groundwater, threatening the safety of drinking water for residents, affecting soil quality, and hindering sustainable agricultural development. Therefore, efficient and reliable wastewater treatment has become a key link in maintaining ecological health and ensuring the quality of human life.

[0003] In existing wastewater treatment devices, filter plates are widely used as key components for intercepting solid impurities and suspended solids in wastewater. Based on physical filtration, they utilize the fine pores set on the filter plate to block impurities with a particle size larger than the pore size from passing through, thereby achieving preliminary purification of wastewater and reducing the burden on subsequent stages such as biological treatment and advanced chemical treatment, laying the foundation for them.

[0004] However, traditional filter plates have a significant drawback: frequent clogging. Due to the diverse sources and complex composition of wastewater, including impurities with different properties and particle sizes such as silt, fibers, and colloidal particles, these impurities easily accumulate on the filter plate surface and become embedded in the filter pores during continuous filtration. Moreover, traditional filter plates are mostly statically installed, passively enduring the impact of wastewater and the sedimentation of impurities, lacking active anti-clogging and cleaning mechanisms. Once operation begins, as the treatment time increases, the clogging of the filter pores gradually worsens, and the resistance of wastewater flowing through the filter plate increases sharply. This not only slows down the filtration speed and reduces the treatment efficiency, but also causes abnormal pressure fluctuations inside the treatment device due to poor water flow, affecting the stability of the entire wastewater treatment system, increasing the risk of equipment damage, and requiring frequent shutdowns for manual cleaning and maintenance, thus increasing operating costs and manpower input.

[0005] To address these issues, we designed an automated wastewater treatment plant. Utility Model Content

[0006] The purpose of this invention is to provide an automated wastewater treatment tank to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the present invention provides an automated sewage treatment tank, including a treatment box. A filter plate is slidably connected inside the treatment box, and sliders are fixedly connected to all four sides of the filter plate. Sliding grooves for sliding of the sliders are opened on the inner side walls of the treatment box. A connecting block is provided at the top of one of the sliders. A through groove is opened on one side wall of the treatment box, and the connecting block is slidably connected in the through groove. A drive box is installed on the outer wall of the through groove. A drive motor is fixedly connected to one side wall of the drive box. An incomplete gear is fixedly connected to the output end of the drive motor. A rack is meshed on one side of the incomplete gear, and the side of the rack away from the incomplete gear is fixedly connected to the connecting block.

[0008] Furthermore, a limiting rod is fixedly connected between the upper and lower inner walls of the drive box, and the toothed rod is slidably sleeved on the limiting rod.

[0009] Furthermore, the connecting block is L-shaped, with its bottom end fixedly connected to the top end of one of the sliders, and the top end of the connecting block extending through the through groove and into the drive box.

[0010] Furthermore, a lead screw is rotatably connected between the top two side walls inside the processing box, a moving block is threaded onto the lead screw, an electric telescopic rod is fixedly connected to the bottom end of the moving block, a scraper is fixedly connected to the drive end of the electric telescopic rod, a chassis is fixedly connected to one side outer wall of the processing box, a servo motor is installed inside the chassis, and the rotating end of the servo motor is connected to the lead screw.

[0011] Furthermore, the length of the lead screw is the same as the length of the filter plate, and the length of the scraper is the same as the width of the filter plate.

[0012] Furthermore, a through hole is provided on one side wall of the treatment box, the bottom end of the through hole is flush with the top end of the filter plate, a baffle is rotatably connected to the bottom end of the through hole, and a handle is fixedly connected to the outside of the baffle.

[0013] Furthermore, a water inlet pipe is fixedly inserted into the top of the treatment box, and a water outlet pipe is fixedly inserted into one side wall of the bottom of the treatment box, with a valve installed inside the water outlet pipe.

[0014] Furthermore, an observation window is installed on one side wall of the processing box.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this utility model, when the filter plate becomes clogged, the drive motor is started, which drives the incomplete gear to rotate. The gear intermittently meshes with the rack, causing the rack to slide up and down along the limiting rod. Then, with the help of the connecting block, the slider slides smoothly in the groove, so that the filter plate oscillates regularly up and down in the treatment box. This oscillation can efficiently shake off various stubborn impurities such as mud, sand, fibers, and colloidal particles embedded and accumulated inside and on the surface of the filter holes, restore the filter plate to its unobstructed state, and ensure that the sewage can continuously and smoothly pass through the filter plate into the subsequent treatment process. This reduces the frequency and duration of treatment interruptions caused by filter plate clogging and maintains the continuity and efficiency of sewage treatment operations.

[0017] 2. In this utility model, when a certain amount of impurities accumulate on the filter plate and need to be cleaned, the servo motor inside the machine is turned on, which drives the lead screw to rotate and drives the moving block to move precisely along the lead screw. Combined with the electric telescopic rod, the height position of the scraper can be flexibly adjusted, so that it can fully and tightly fit the surface of the filter plate and thoroughly scrape away and clean the intercepted and retained impurities. The whole process does not require manual operation into the processing box, avoiding complex, heavy and unhygienic cleaning procedures, and greatly saving manpower. Attached Figure Description

Detailed Implementation

[0023] 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 protection scope of the present utility model.

[0024] Please see Figure 1 and Figure 2 This utility model provides a technical solution: an automated sewage treatment tank, including a treatment box 1. A filter plate 2 is slidably connected inside the treatment box 1. Slider 4s are fixedly connected to all four sides of the filter plate 2. Sliding grooves 3 are provided on the inner side walls of the treatment box 1 for the slider 4 to slide. A connecting block 5 is provided at the top of one of the slider 4s. A through groove 6 is provided on one side wall of the treatment box 1. The connecting block 5 is slidably connected in the through groove 6. A drive box 7 is installed on the outer wall of the through groove 6. A drive motor is fixedly connected to one side wall of the drive box 7. An incomplete gear 10 is fixedly connected to the output end of the drive motor. A rack 9 is meshed on one side of the incomplete gear 10. The side of the rack 9 away from the incomplete gear 10 is fixedly connected to the connecting block 5.

[0025] In practice, when the filter holes of filter plate 2 become clogged, making it difficult for sewage to flow smoothly down from filter plate 2, the drive motor located on one side wall of drive box 7 is activated. The drive motor drives the incomplete gear 10 fixedly connected to the output end to rotate clockwise. When the incomplete gear 10 rotates clockwise, it intermittently meshes with the rack 9. When the incomplete gear 10 and the rack 9 are meshed, the rack 9 moves upward. When the incomplete gear 10 and the rack 9 are disengaged, the rack 9 moves downward under the action of gravity. In addition, the rack... A spring is installed at the top of the rack 9, which is sleeved on the limit rod 8. When the rack 9 moves upward under the action of the incomplete gear 10, the rack 9 will compress the spring. When the rack 9 loses engagement, the spring will quickly rebound, causing the rack 9 to fall rapidly. This process realizes the up and down movement of the rack 9. This movement is transmitted through the connecting block 5, which drives the slider 4 to slide up and down in the slide groove 3, thereby causing the filter plate 2 to oscillate up and down inside the treatment box 1. By means of the vibration generated by the oscillation, the impurities blocked in the filter holes are shaken off, restoring the filtration efficiency of the filter plate 2.

[0026] See Figure 2 A limit rod 8 is fixedly connected between the upper and lower inner walls of the drive box 7, and a toothed rod 9 is slidably sleeved on the outside of the limit rod 8.

[0027] In practice, when the incomplete gear 10 rotates, it will intermittently mesh with the rack 9, driving the rack 9 to slide up and down along the limiting rod 8. The limiting rod 8 will guide the rack 9 to slide up and down.

[0028] See Figure 3 The connecting block 5 is L-shaped. The bottom end of the connecting block 5 is fixedly connected to the top end of one of the sliders 4. The top end of the connecting block 5 passes through the through groove 6 and extends into the drive box 7.

[0029] In practice, the L-shaped connecting block 5 can increase the distance between the through slot 6 and the slider 4, providing a suitable spatial layout between the toothed rod 9 and the slider 4.

[0030] See Figure 2 A lead screw 11 is rotatably connected between the top two side walls inside the processing box 1. A moving block 12 is threaded onto the lead screw 11. An electric telescopic rod 13 is fixedly connected to the bottom end of the moving block 12. A scraper 14 is fixedly connected to the drive end of the electric telescopic rod 13. A housing 15 is fixedly connected to one outer wall of the processing box 1. A servo motor is installed inside the housing 15. The rotating end of the servo motor is connected to the lead screw 11. The length of the lead screw 11 is the same as the length of the filter plate 2. The length of the scraper 14 is the same as the width of the filter plate 2.

[0031] In practice, when cleaning the impurities accumulated on the filter plate 2, the servo motor installed in the housing 15 is turned on. The rotating end of the servo motor is connected to the lead screw 11 that is rotatably connected between the top two side walls of the processing box 1. The moving block 12 threaded on the lead screw 11 moves horizontally under the rotation of the lead screw 11. The electric telescopic rod 13 fixedly connected to the bottom of the moving block 12 can be adjusted in length as needed. The scraper 14 fixedly connected to its drive end has the same length as the width of the filter plate 2, which can effectively cover the surface of the filter plate 2. The moving block 12 is moved by the rotation of the lead screw 11, and the position height of the scraper 14 is adjusted in conjunction with the electric telescopic rod 13 to achieve scraping and cleaning of impurities on the filter plate 2.

[0032] See Figure 1 and Figure 2 The processing box 1 has a through hole on one side wall. The bottom end of the through hole is flush with the top end of the filter plate 2. A baffle 16 is rotatably connected to the bottom end of the through hole. A handle 17 is fixedly connected to the outside of the baffle 16.

[0033] In practice, when impurities are scraped to the through hole, the baffle 16 can be opened by manually turning the handle 17, allowing the impurities to be discharged outside the treatment box 1.

[0034] See Figure 4 A water inlet pipe 18 is fixedly inserted into the top of the treatment box 1, and a water outlet pipe 19 is fixedly inserted into one side wall of the bottom of the treatment box 1. A valve 20 is installed inside the water outlet pipe 19.

[0035] In practice, the outlet pipe 19, which is fixedly inserted into one side wall at the bottom of the treatment tank 1, can discharge the treated water that meets the standards as needed under the control of the valve 20 installed inside.

[0036] See Figure 1 An observation window 21 is installed on one side wall of the processing box 1.

[0037] In practice, the sewage injection volume is monitored in real time using the observation window 21 installed on one side wall of the treatment box 1 to ensure that it does not exceed the preset scale line, that is, does not exceed the bottom position of the through channel 6.

[0038] Working principle:

[0039] Before use, connect the sewage to the inlet pipe 18 fixedly inserted at the top of the treatment tank 1 to allow the sewage to enter the treatment tank 1. Use the observation window 21 installed on one side wall of the treatment tank 1 to observe the sewage injection volume in real time and ensure that it does not exceed the preset scale line, that is, it does not exceed the bottom position of the through groove 6. When the sewage flows into the treatment tank 1, it will first pass through the filter plate 2 that is slidably connected inside. The impurity particles in the sewage will be intercepted above the filter plate 2.

[0040] As usage time increases, impurities easily clog the filter holes of filter plate 2, making it difficult for sewage to flow smoothly down the filter plate 2. At this time, the drive motor located on one side wall of the drive box 7 is started. The drive motor drives the incomplete gear 10 fixedly connected to the output end to rotate. Since the incomplete gear 10 is meshed with the rack 9, and the rack 9 is fixed to the connecting block 5 on the side away from the incomplete gear 10, and the bottom end of the connecting block 5 is connected to the top end of the slider 4, the rack 9 is slidably sleeved on the limit rod 8 fixedly connected between the upper and lower inner walls of the drive box 7. When the incomplete gear 10 rotates, it will intermittently mesh with the rack 9. The rack 9 is driven to slide up and down along the limit rod 8 and under the action of the spring at its top end. This movement is transmitted through the connecting block 5, which drives the slider 4 to slide up and down in the slide groove 3, thereby causing the filter plate 2 to oscillate up and down inside the treatment box 1. The vibration generated by the oscillation shakes off the impurities clogging the filter holes, restoring the filtration efficiency of the filter plate 2.

[0041] When cleaning the impurities accumulated on the filter plate 2, the servo motor installed in the housing 15 is turned on. The rotating end of the servo motor is connected to the lead screw 11 that is rotatably connected between the top two side walls of the processing box 1. The length of the lead screw 11 is adapted to the length of the filter plate 2. The moving block 12 threaded on the lead screw 11 moves horizontally when the lead screw 11 rotates. The electric telescopic rod 13 fixedly connected to the bottom of the moving block 12 can be adjusted in length as needed. The scraper 14 fixedly connected to its drive end has the same length as the width of the filter plate 2 and can effectively cover the surface of the filter plate 2. The moving block 12 is moved by rotating the lead screw 11. The position and height of the scraper 14 are adjusted in conjunction with the electric telescopic rod 13 to achieve scraping and cleaning of impurities on the filter plate 2.

[0042] A through hole is provided on one side wall of the treatment tank 1. The bottom end of the through hole is flush with the top end of the filter plate 2 and is rotatably connected to a baffle 16. A handle 17 is installed on the outside of the baffle 16. When impurities are scraped to the through hole, the baffle 16 can be opened by manually turning the handle 17, so that the impurities can be discharged out of the treatment tank 1. The water outlet pipe 19 is fixedly inserted into one side wall at the bottom of the treatment tank 1. Under the control of the valve 20 installed inside, the treated water that meets the standards in the treatment tank 1 can be discharged as needed, thus completing the entire sewage treatment process.
