Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater sedimentation and separation device. Background Technology
[0002] Industrial wastewater refers to wastewater, sewage, and waste liquid generated during industrial production processes. It contains industrial production materials, intermediate products, and finished products lost with the water, as well as pollutants generated during the production process. The commonly used sewage sedimentation device is the sedimentation tank. By injecting the sewage to be treated into the sedimentation device, the principle of contact flocculation is used to remove suspended solids in the water, thereby achieving sedimentation for sewage treatment. During the sewage treatment process, sludge will be deposited at the bottom of the sedimentation device. In order to ensure the normal operation of sewage treatment, it is necessary to drain the sedimentation tank in a timely manner and remove the sludge deposited at the bottom.
[0003] For example, announcement number CN221014638U, entitled "A Sedimentation Device," includes a sedimentation tank. Drive slots are respectively provided above the front and rear of the sedimentation tank. A slider is slidably connected in the front drive slot, and a sliding rod is provided in the front drive slot. A drive block is slidably connected in the rear drive slot, and a threaded rod is provided in the rear drive slot. The threaded rod is threadedly connected to the drive block. A servo motor is provided on the right side of the sedimentation tank, with its end passing through the right side of the sedimentation tank and connected to the threaded rod. Support blocks are detachably provided above the drive block and slider. A sludge scraping assembly is provided between the bottoms of the two support blocks. A sludge collection trough is provided at the bottom left side of the sedimentation tank. The sludge scraping assembly includes a cleaning frame detachably provided between the bottoms of the two support blocks. A sludge scraper is provided on the bottom horizontal plate of the cleaning frame, and the sludge scraper fits against the bottom of the sedimentation tank, enabling the removal of sludge deposited at the bottom of the sedimentation device.
[0004] The existing sedimentation devices can only push the sludge forward during the sludge scraping process. They are not very effective at scraping solidified sludge and cannot break up the sludge. Therefore, they do not meet the current requirements. In response, a wastewater sedimentation and separation device is proposed. Utility Model Content
[0005] The purpose of this invention is to provide a wastewater sedimentation and separation device to solve the problem mentioned in the background art that existing sedimentation devices can only push the sludge forward during the sludge scraping process, and the scraping effect on solidified sludge is poor, making it impossible to break up the sludge.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a wastewater sedimentation and separation device, comprising: a sedimentation tank, on both sides of the upper surface of the sedimentation tank being equipped with displacement components, a lifting scraper assembly being installed above the displacement components, a crushing and guiding assembly being installed on the outer wall of the lifting scraper assembly, and a sludge crushing and discharge assembly being provided at the bottom of one end of the sedimentation tank.
[0007] Preferably, the lifting scraper assembly includes a support frame, an electric telescopic rod is installed above the support frame, a push plate is installed at the telescopic end of the electric telescopic rod, and a plurality of horizontally spaced scraper teeth are installed at the front end of the bottom of the push plate.
[0008] Preferably, the crushing guide assembly includes a first rotating roller, which is mounted above the shovel teeth, and a plurality of sets of transversely spaced crushing blades are mounted on the outer wall of the first rotating roller.
[0009] Preferably, the pulverizing guide assembly further includes a first motor mounted on the upper surface of the support frame, a first synchronous pulley mounted on the output end of the first motor, a second synchronous pulley mounted on one end of the first roller, and a synchronous belt mounted between the first synchronous pulley and the second synchronous pulley.
[0010] Preferably, the displacement assembly includes a ball screw and a guide rod, both of which have sliders installed on their outer walls, and a screw motor is installed at one end of the ball screw.
[0011] Preferably, the sludge crushing and discharging assembly includes a sludge discharge outlet, and inclined guide plates are installed on both sides above the sludge discharge outlet.
[0012] Preferably, a second rotating roller is installed at the middle position above the sludge discharge outlet, and multiple sets of horizontally spaced arc-shaped cutting blades are arranged on the outer wall of the second rotating roller, and a second motor is installed on the outer wall of the second rotating roller.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] (1) In this utility model, the screw motor drives the slider to slide on the ball screw, and during the displacement, it drives the push plate to move, so that the push plate can move from one end of the sedimentation tank to the other end, thereby making it convenient for users to scrape the sludge at the bottom of the sedimentation tank to the sludge crushing and discharge component for discharge. Before scraping, the height of the push plate is adjusted by the electric telescopic rod, so that the push plate moves to the bottom of the tank, and then the shovel teeth at the bottom of the push plate scrape the sludge at the bottom of the tank by displacement, so as to achieve the effect of treating the sludge in the wastewater sedimentation tank. After scraping the sludge, the push plate can also be moved to the outside of the sedimentation tank by the electric telescopic rod, so that users can clean, replace and repair the push plate.
[0015] (2) In this utility model, when the displacement scraper is moved at the push plate, the first synchronous wheel is driven to rotate by the first motor. The first synchronous wheel is connected to the second synchronous wheel through the synchronous belt, which can drive the first rotating roller to rotate. Several crushing blades on the outer wall of the first rotating roller crush the shoveled sludge and guide the sludge to move downward as it rotates, so that the sludge scraper at the push plate can fall below after it moves to the sludge discharge outlet.
[0016] (3) In this utility model, the inclined guide plate is used to guide the sludge to slide down. The second motor drives the second roller to rotate, so that the arc-shaped cutting blade can crush the sludge at this position, ensuring that the sludge is not easy to block the position and improving the sludge discharge effect.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Please see Figure 1-4This utility model provides an embodiment of a wastewater sedimentation and separation device, comprising: a sedimentation tank 1, displacement components 2 installed on both sides of the upper surface of the sedimentation tank 1, a lifting scraper assembly 3 installed above the displacement components 2, a crushing and guiding assembly 4 installed on the outer wall of the lifting scraper assembly 3, and a sludge crushing and discharge assembly 5 provided at the bottom of one end of the sedimentation tank 1. The lifting scraper assembly 3 includes a support frame 301, an electric telescopic rod 302 installed above the support frame 301, a push plate 303 installed at the telescopic end of the electric telescopic rod 302, and a plurality of horizontally spaced scraper teeth 304 installed at the front end of the bottom of the push plate 303. The displacement component 2 includes a ball screw 201 and a guide rod 203, and sliders 204 are installed on the outer walls of both the ball screw 201 and the guide rod 203. A screw is installed at one end of the ball screw 201. Motor 202; The lead screw motor 202 drives the slider 204 to slide on the ball screw 201. During the displacement, it drives the push plate 303 to move, so that the push plate 303 can move from one end of the sedimentation tank 1 to the other end. This allows the user to easily scrape the sludge at the bottom of the sedimentation tank 1 to the sludge crushing and discharge component 5 for discharge. Before scraping, the height of the push plate 303 is adjusted by the electric telescopic rod 302, so that the push plate 303 moves to the bottom of the tank. Then, by displacement, the shovel teeth 304 at the bottom of the push plate 303 scrapes the sludge at the bottom of the tank, so as to achieve the effect of treating the sludge in the wastewater sedimentation tank 1. After scraping, the push plate 303 can also be moved to the outside of the sedimentation tank 1 by the electric telescopic rod 302, so that the user can easily clean, replace and maintain the push plate 303.
[0024] Furthermore, such as Figure 3 As shown, the crushing and guiding assembly 4 includes a first rotating roller 405, which is mounted above the shovel teeth 304. Multiple sets of transversely spaced crushing blades 406 are mounted on the outer wall of the first rotating roller 405. The crushing and guiding assembly 4 also includes a first motor 401 mounted on the upper surface of the support frame 301. A first synchronous pulley 402 is mounted at the output end of the first motor 401. A second synchronous pulley 403 is mounted at one end of the first rotating roller 405. A synchronous belt 4 is installed between the first synchronous pulley 402 and the second synchronous pulley 403. 04; When the sludge is displaced and scraped at the push plate 303, the first motor 401 drives the first synchronous wheel 402 to rotate. The first synchronous wheel 402 is connected to the second synchronous wheel 403 through the synchronous belt 404, which drives the first rotating roller 405 to rotate. Several crushing blades 406 on the outer wall of the first rotating roller 405 break up the sludge being scraped and guide the sludge downward as it rotates, so that after it moves to the sludge discharge outlet 505, the sludge scraper at the push plate 303 can be dropped below.
[0025] Please see Figure 4The sludge crushing and discharging assembly 5 includes a sludge discharge outlet 505. Inclined guide plates 501 are installed on both sides above the sludge discharge outlet 505. A second rotating roller 503 is installed at the middle position above the sludge discharge outlet 505. Multiple sets of horizontally spaced arc-shaped cutting blades 504 are arranged on the outer wall of the second rotating roller 503. A second motor 502 is installed on the outer wall of the second rotating roller 503. The sludge discharge outlet 505 is used to discharge sludge. The inclined guide plates 501 are used to guide the sludge to slide downwards. The second rotating roller 503 is driven by the second motor 502 to rotate, so that the arc-shaped cutting blades 504 crush the sludge at this position, further reducing the sludge volume, ensuring that the sludge is not easy to clog the position, and improving the sludge discharge effect.
