Description

Technical Field

[0001] The present application relates to the technical field of sewage treatment tanks, and more specifically, to a sewage treatment tank. Background Art

[0002] Sewage usually refers to the discharged water from life and production that is polluted to a certain extent. Sewage mainly includes domestic sewage, industrial wastewater and initial rainwater. The main pollutants in sewage include pathogen pollutants, oxygen-consuming pollutants, plant nutrients and toxic pollutants. In daily life, sewage can be found everywhere, so it is necessary to use sewage treatment pools to treat sewage. During the use of existing sewage treatment pools, silt is easily accumulated at the bottom of the pool, and more pollutants are easily attached to the surface of the filter plate, and it is difficult to clean it, which can easily cause damage to the sewage treatment pool, affect normal work, and reduce utilization.

[0003] The document with prior art publication number CN219681779U provides a new type of sewage treatment tank. The device can precipitate sludge and pollutants in sewage through a first sedimentation tank and a second sedimentation tank, thereby reducing the amount of pollutants attached to the surface of the filter medium during the later sewage filtration, thereby increasing the difficulty of later cleaning of the sewage treatment tank and affecting the use effect of the sewage treatment tank; through the provided cylinder, connecting rod, slide chute and scraper, impurities and pollutants inside the second sedimentation tank can be scraped off and collected inside the first sedimentation tank, which is convenient for treating the sludge and pollutants inside the first sedimentation tank and improves the use efficiency of the treatment tank body.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: the device cannot intercept floating objects and suspended matter in sewage during use, thus causing a large amount of suspended matter or a small amount of floating matter to enter the filter medium, thereby increasing the filtration burden of the filter medium.

[0005] Regarding the above-mentioned related technologies, the inventor believes that the device cannot intercept floating matter and suspended matter in sewage during use, which will cause a large amount of suspended matter or a small amount of floating matter to enter the filter medium, thereby increasing the filtration burden of the filter medium.

[0006] In view of this, we propose a sewage treatment pool. Utility Model Content

[0011] By adopting the above technical solution, the water inlet pipe and the water outlet pipe are both lower than the sludge scraper mesh plate, and the sewage enters the sedimentation tank through the water inlet pipe, and is precipitated through the sedimentation bin and the advection bin. When the sludge scraper mesh plate is placed on the right side, the cleaning mechanism is placed under the sedimentation tank under the action of gravity and keeps a certain distance from the sedimentation tank. At this time, the sludge scraper mesh plate blocks floating objects and suspended objects in the sewage. When it is necessary to clean the sludge deposited at the bottom of the sludge scraper mesh plate and the advection bin, the sludge scraper mesh plate is driven by the linear module to slide from left to right, and the sludge scraper mesh plate cleans the sludge at the bottom of the advection bin to the sedimentation bin. Finally, the sediment in the sedimentation bin can be discharged by opening the valve. In this process, the cleaning mechanism moves upward under the action of the slope of the sludge scraper mesh plate, and cleans the left side of the sludge scraper mesh plate from bottom to top, thereby ensuring the normal filtering effect of the sludge scraper mesh plate.

[0012] As an optional solution of the technical solution of the present application document, horizontal guide rails are symmetrically fixed to the inner wall of the sedimentation tank, second slide grooves adapted to the guide rails are opened on both sides of the scraper mesh, and a vertical first slide groove is symmetrically opened inside the sedimentation tank. The cleaning mechanism includes a brush plate and sliders fixed at both ends of the brush plate and adapted to the first slide groove, the linear module includes a servo motor and a screw rod coaxially fixed to the output shaft of the servo motor and a nut threadedly connected to the screw rod, and the nut is fixed on the scraper mesh.

[0015] By adopting the above technical solution, the scraper is made of rubber material to avoid scratching the bottom wall of the advection bin during cleaning.

[0016] As an optional solution of the technical solution of the present application document, bearings are fixedly installed at both ends of the brush plate, and the inner ring of the bearing is fixedly connected to the brush plate.

[0017] By adopting the above technical solution, when the scraper mesh plate abuts against the outer ring of the bearing, the bristles of the brush plate abut against the scraper mesh plate and bend. When the scraper mesh plate slides to the left, under the action of the bearing, the scraper mesh plate and the brush plate are prevented from interfering with each other, thereby ensuring the upward sliding of the brush plate.

[0029] The present application is further described in detail below in conjunction with the accompanying drawings.

[0030] A sewage treatment tank includes a sedimentation tank 1, wherein the sedimentation tank 1 includes an inlet pipe 101, an outlet pipe 102, a horizontal flow chamber 103 and a sedimentation chamber 104 with a valve 1041. The inlet pipe 101 is placed on the side of the sedimentation chamber 104. A sludge scraping mesh plate 2 inclined toward the sedimentation chamber 104 is slidably arranged in the sedimentation tank 1, and the sludge scraping mesh plate 2 is fitted with the horizontal flow chamber 103. A linear module 3 for driving the sludge scraping mesh plate 2 to reciprocate is fixedly installed on the sedimentation tank 1. A cleaning mechanism 4 is slidably arranged inside the sedimentation tank 1, and the cleaning mechanism 4 slides up and down along the sedimentation tank 1. The cleaning mechanism 4 is placed on the slope side of the sludge scraping mesh plate 2.

[0031] Reference Figure 1-Figure 5 , the water inlet pipe 101 and the water outlet pipe 102 are both lower than the sludge scraper mesh plate 2, the sewage enters the sedimentation tank 1 through the water inlet pipe 101, and is precipitated through the sedimentation bin 104 and the advection bin 103. When the sludge scraper mesh plate 2 is placed on the right side, the cleaning mechanism 4 is placed below the sedimentation tank 1 under the action of gravity and keeps a certain distance from the sedimentation tank 1. At this time, the sludge scraper mesh plate 2 blocks the floating objects and suspended objects in the sewage. When it is necessary to clean the sludge deposited at the bottom of the sludge scraper mesh plate 2 and the advection bin 103, the sludge scraper mesh plate 2 is driven by the linear module 3 to slide from left to right, and the sludge scraper mesh plate 2 cleans the sludge at the bottom of the advection bin 103 to the sedimentation bin 104. Finally, the sediment in the sedimentation bin 104 can be discharged by opening the valve 1041. In this process, the cleaning mechanism 4 moves upward under the action of the slope of the sludge scraper mesh plate 2, and cleans the left side of the sludge scraper mesh plate 2 from bottom to top, thereby ensuring the normal filtering effect of the sludge scraper mesh plate 2.

[0032] A horizontal guide rail 105 is symmetrically fixed to the inner wall of the sedimentation tank 1, and a second slide groove 201 adapted to the guide rail 105 is opened on both sides of the scraper mesh plate 2. A vertical first slide groove 106 is symmetrically opened inside the sedimentation tank 1. The cleaning mechanism 4 includes a brush plate 401 and sliders 402 fixed at both ends of the brush plate 401 and adapted to the first slide groove 106. The linear module 3 includes a servo motor 301 and a screw rod 302 coaxially fixed to the output shaft of the servo motor 301 and a nut 303 threadedly connected to the screw rod 302. The nut 303 is fixed on the scraper mesh plate 2.

[0033] Reference Figure 2-Figure 5 The scraper mesh plate 2 slides horizontally along the guide rail 105, and the first slide groove 106 is placed under the guide rail 105, and the slider 402 cooperates with the first slide groove 106 to make the brush plate 401 slide up and down along the first slide groove 106, and when the brush plate 401 is not in contact with the scraper mesh plate 2, the brush plate 401 slides downward under the action of gravity, and the servo motor 301 is fixed on the sedimentation tank 1. Through the cooperation of the screw rod 302 and the nut 303, when the screw rod 302 rotates, it drives the nut 303 and the scraper mesh plate 2 to slide left and right along the sedimentation tank 1 to realize the cleaning of the sludge in the leveling bin 103.

[0034] A scraper 202 made of rubber material is fixedly mounted on the lower end of the scraper mesh plate 2.

[0035] Reference Figure 4 The scraper 202 is made of rubber to avoid scratching the bottom wall of the advection chamber 103 during cleaning.

[0036] Bearings 403 are fixedly installed at both ends of the brush plate 401 , and the inner ring of the bearing 403 is fixedly connected to the brush plate 401 .

[0037] Reference Figure 2 and Figure 5 When the scraper mesh plate 2 abuts against the outer ring of the bearing 403, the bristles of the brush plate 401 abut against the scraper mesh plate 2 and bend. When the scraper mesh plate 2 slides to the left, under the action of the bearing 403, the scraper mesh plate 2 and the brush plate 401 are prevented from interfering with each other, thereby ensuring the upward sliding of the brush plate 401.

[0038] The bristles of the brush plate 401 on one side close to the sludge scraping mesh plate 2 are wire brushes.

[0039] Wire brushes are acid and alkali resistant, wear resistant, durable, not easy to break, and have a relatively long service life.

[0040] Working principle: sewage enters the sedimentation tank 1 through the water inlet pipe 101, and is precipitated through the sedimentation bin 104 and the advection bin 103. In this process, the sewage passes through the sludge scraper mesh plate 2 to filter the floating objects and suspended objects in the sewage. When it is necessary to clean the sludge at the bottom of the scraper mesh plate 2 and the advection bin 103, the servo motor 301 drives the screw rod 302 to rotate counterclockwise, so that the nut 303 drives the scraper mesh plate 2 to slide to the left, and the scraper plate 202 cleans the sludge at the bottom of the advection bin 103 to the sedimentation bin 104, and when the scraper mesh plate 2 is against the brush plate 401, the brush plate 401 cleans the surface of the scraper mesh plate 2 during the upward sliding process.
