Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a rapid separation structure for a wastewater treatment device. Background Technology

[0002] Wastewater treatment refers to the removal of pollutants from wastewater from communities, industries, or other sources using physical, chemical, and biological methods to protect the environment and water resources. Its purpose is to reduce the concentration of pollutants in water so that the treated water can be safely discharged into natural water bodies or reused. Wastewater often contains solid impurities, which usually require separation to prevent their accumulation in pipes and obstruction of wastewater flow. Rapidly separating solid impurities during wastewater treatment prevents them from damaging subsequent treatment equipment.

[0003] In the prior art, such as Chinese Patent No. CN220223657U, a sewage treatment device with an anti-clogging structure is disclosed, including a sewage treatment tank. A separation tank is fixedly connected to the upper part of the sewage treatment tank. A primary filter plate is fixedly inserted through the bottom right side of the separation tank, which is inclined from right to left. A drainage hole is opened on the bottom left side of the separation tank, located to the left of the primary filter plate. A pulverizing tank is connected to the bottom left side of the separation tank through the drainage hole. A first chassis is fixedly connected to the bottom of the pulverizing tank. Solid waste is filtered out by the primary filter plate and transported to the inside of the pulverizing tank through the drainage hole. The first motor is started, which drives the pulverizing shaft and pulverizing blades to rotate rapidly, thereby quickly pulverizing the solid waste inside the pulverizing tank, preventing solid waste from clogging the sewage pipe, reducing the maintenance frequency of the sewage treatment device, and extending the service life of the sewage treatment device.

[0004] However, in existing technologies, wastewater treatment devices typically employ an inclined filter screen for rapid wastewater separation. After passing through this screen, the separated solid impurities fall through the screen's inclined surface into a grinding chamber for further processing. When the friction between the solid impurities and the filter screen surface is excessive, they cannot smoothly slide into the grinding chamber. This is especially true when the solid impurities are sticky or the filter screen surface is rough; the friction hinders their movement, causing them to remain on the screen surface. As more and more impurities accumulate, the separation speed and effectiveness of the wastewater treatment process are affected, ultimately impacting the overall wastewater treatment outcome. Utility Model Content

[0005] The purpose of this invention is to solve the problem in existing wastewater treatment devices where, during wastewater separation, excessive friction between solid impurities and the filter screen surface prevents them from smoothly sliding into the crushing box at the bottom of the filter screen, causing solid impurities to remain on the filter screen surface and accumulate, thus affecting the separation speed and effect of wastewater treatment. Therefore, this invention proposes a rapid separation structure for wastewater treatment devices.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rapid separation structure for a sewage treatment device, comprising a sewage stirring processor, a filtration and separation component disposed at the top of the sewage stirring processor, and a pulverizing component disposed at the bottom of the filtration and separation component;

[0007] The filtration and separation assembly includes a separation box. An installation plate is fixedly installed on one outer surface of the separation box. A forward and reverse motor is fixedly installed inside the installation plate. A lead screw is fixedly installed at the output end of the forward and reverse motor. A moving block is threaded onto the outer surface of the lead screw. Two sliding rods are fixedly installed on the rear surface of the moving block. A moving rod is fixedly installed at one end of the two sliding rods. A pusher plate is fixedly installed on the outer surface of the moving rod. A filtration and separation plate is fixedly installed inside the separation box.

[0008] Preferably, the top of the separation box has a light-transmitting hole, a transparent plate is fixedly installed inside the light-transmitting hole, a camera is fixedly installed at the bottom of the transparent plate, a protective plate is provided on the outer surface of the camera, the top of the protective plate is fixedly installed at the bottom of the transparent plate, a conical frame is fixedly installed inside the separation box, and the bottom of the filter separation plate is fixedly installed at the top of the conical frame near one side.

[0009] Preferably, a discharge pipe is fixedly connected to the bottom of the conical frame, the bottom end of the discharge pipe extends movably to the bottom of the separation box, a drain pipe is fixedly connected to the bottom of the separation box, the bottom end of the drain pipe is fixedly installed on the top of the sewage mixing processor, and a water inlet pipe is fixedly connected to the top of the separation box near the edge.

[0010] Preferably, a fixing block is fixedly installed on the other outer surface of the separation box, one end of the lead screw is movably embedded in the outer surface of one side of the fixing block, a sliding hole is opened on the front surface of the separation box, the outer surfaces of the two sliding rods are movably embedded in the sliding hole, a sliding groove is opened on the rear surface wall inside the separation box, one end of the moving rod is movably embedded in the sliding groove, and the bottom of the pusher plate is in contact with the top of the filter separation plate.

[0011] Preferably, the crushing assembly includes a crushing box, a slag receiving frame is provided at the bottom of the crushing box, a servo motor is installed on the top of the crushing box via an auxiliary plate, and a rotating shaft is fixedly installed at the output end of the servo motor.

[0012] Preferably, the bottom end of the rotating shaft is movably embedded in the bottom surface inside the crushing box, a plurality of crushing blades are fixedly installed on the outer surface of the rotating shaft, a scraper is fixedly installed on the outer surface of the rotating shaft near the bottom end, and a discharge pipe is fixedly connected to the bottom of the crushing box.

[0013] Preferably, a valve is provided on the outer surface of the discharge pipe, the bottom end of the discharge pipe is fixedly connected to the top of the crushing box, and the bottom of the separation box is installed on the top of the sewage mixing processor via an auxiliary rod.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, a camera captures real-time images of the impurities on the surface of the filter separation plate. When solid impurities accumulate on the surface of the filter separation plate, wastewater injection is paused, and the forward and reverse motors are started to drive the lead screw to rotate. This drives the moving block, slide bar, and moving rod to move towards the conical frame, causing the pusher plate to move and push the accumulated solid impurities on the filter separation plate into the conical frame. Then, the output end of the forward and reverse motors rotates in the opposite direction, driving the pusher plate to move in the opposite direction and reset. Wastewater injection continues, and the filtration and separation process is completed. Under the action of the filtration and separation component, impurities on the surface of the filter separation plate can be effectively pushed into the conical frame, thereby achieving a cleaning effect and preventing impurities from accumulating on the filter screen surface and affecting the subsequent wastewater separation effect.

[0016] 2. In this utility model, the servo motor is started to drive the rotating shaft and the crushing blade to rotate, crushing the impurities in the crushing box. After crushing, the valve is opened, and the crushed impurities are discharged into the slag collection frame through the discharge pipe for collection. At the same time, the rotating shaft drives the scraper to rotate, pushing the impurities on the bottom of the crushing box to the discharge pipe for better discharge. It is not necessary to discharge the crushed solid impurities into the filtered wastewater for further treatment, reducing the burden on the subsequent treatment unit and improving the overall wastewater treatment efficiency.

[0025] Example 1, such as Figures 1-5As shown, this utility model provides a rapid separation structure for a wastewater treatment device, including a wastewater stirring processor 1, a filtration and separation component 2 disposed on the top of the wastewater stirring processor 1, and a pulverizing component 3 disposed on the bottom of the filtration and separation component 2; the filtration and separation component 2 includes a separation box 201, an mounting plate 202 fixedly mounted on one outer surface of the separation box 201, a forward and reverse motor 203 fixedly mounted inside the mounting plate 202, a lead screw 204 fixedly mounted on the output end of the forward and reverse motor 203, and a movable threaded part on the outer surface of the lead screw 204. Block 205, two sliding rods 207 are fixedly installed on the rear surface of the movable block 205, and a moving rod 208 is fixedly installed at one end of the two sliding rods 207. A pusher plate 209 is fixedly installed on the outer surface of the moving rod 208. A filter separation plate 217 is fixedly installed inside the separation box 201. A light-transmitting hole 212 is opened on the top of the separation box 201. A transparent plate 213 is fixedly installed inside the light-transmitting hole 212. A camera 215 is fixedly installed at the bottom of the transparent plate 213. A protective plate 214 is provided on the outer surface of the camera 215. The top of plate 214 is fixedly installed on the bottom of transparent plate 213. A conical frame 219 is fixedly installed inside the separation box 201. The bottom of filter separation plate 217 is fixedly installed on the top of the conical frame 219 near one side. A discharge pipe 220 is fixedly connected to the bottom of the conical frame 219. The bottom end of the discharge pipe 220 extends movably through to the bottom of the separation box 201. A drain pipe 218 is fixedly connected to the bottom of the separation box 201. The bottom end of the drain pipe 218 is fixedly installed on the top of the wastewater mixing processor 1. The top of the separation box 201 is near the edge. A water inlet pipe 216 is fixedly connected to the separation box 201. A fixing block 206 is fixedly installed on the other outer surface of the separation box 201. One end of the screw 204 is movably embedded in the outer surface of one side of the fixing block 206. A sliding hole 211 is opened on the front surface of the separation box 201. The outer surfaces of the two sliding rods 207 are movably embedded in the sliding hole 211. A sliding groove 210 is opened on the rear surface wall inside the separation box 201. One end of the moving rod 208 is movably embedded in the sliding groove 210. The bottom of the pusher plate 209 is in contact with the top of the filter separation plate 217.

[0026] The overall effect of Embodiment 1 is that the forward and reverse motor 203, camera 215, and servo motor 303 are all electrically connected to an external controller. Wastewater is discharged into the separation tank 201 through the inlet pipe 216, and solid-liquid separation is performed through the filter separation plate 217. The separated wastewater enters the wastewater mixing processor 1 through the drain pipe 218 for further processing. The wastewater mixing processor 1 includes a stirrer, a liquid injection pipe, a sewage discharge pipe, and control valves, which are existing mature technologies and will not be described in detail here. The solid impurities separated by filtration are guided to the conical frame 219 through the inclined surface of the filter separation plate 217, and then enter the crushing assembly 3 through the discharge pipe 220 for crushing. The camera 215 captures real-time images of the impurities on the surface of the filter separation plate 217. Simultaneously, the camera transmits the captured images to an external display via electrical signals. Operators can view the surface of the filter separation plate 217 on the external display. When solid impurities are found to have accumulated on the surface of the filter separation plate 217, wastewater injection is paused, and the forward and reverse motor 203 is activated. The rotation of the output end of the forward and reverse motor 203 drives the lead screw 204 to rotate, which in turn moves the moving block 205. This further moves the slide bar 207 and the moving rod 208 towards the conical frame 219, causing the pusher plate 209 to move and push the accumulated solid impurities on the filter separation plate 217 into the conical frame 219. Then, the output end of the forward and reverse motor 203 rotates in the reverse direction, causing the pusher plate 209 to move in the reverse direction and reset. Wastewater injection then resumes for filtration and separation. Under the action of the filter separation component 2, impurities on the surface of the filter separation plate 217 can be effectively pushed into the conical frame 219, thereby achieving a cleaning effect and preventing impurities from accumulating on the filter screen surface, which would affect the subsequent sewage separation effect. This solves the problem in the prior art where, when sewage treatment devices are separating sewage, if the friction between solid impurities and the filter screen surface is too great, they will not be able to slide smoothly into the crushing box at the bottom of the filter screen, causing solid impurities to remain on the filter screen surface and accumulate more and more, affecting the sewage separation speed and effect, and thus affecting the sewage treatment effect.

[0027] Example 2, as Figures 1-5As shown, the filtration and separation assembly 2 includes a separation box 201, inside which a conical frame 219 is fixedly installed. A discharge pipe 220 is fixedly connected to the bottom of the conical frame 219, and the bottom end of the discharge pipe 220 extends movably through to the bottom of the separation box 201. The crushing assembly 3 includes a crushing box 301, with a slag-receiving frame 302 at the bottom. A servo motor 303 is mounted on the top of the crushing box 301 via an auxiliary plate. A rotating shaft 304 is fixedly installed at the output end of the servo motor 303. The bottom end of the shaft 304 is movably embedded in the bottom surface inside the crushing box 301. Multiple crushing blades 305 are fixedly installed on the outer surface of the shaft 304. A scraper 306 is fixedly installed on the outer surface of the shaft 304 near the bottom end. A discharge pipe 307 is fixedly connected to the bottom of the crushing box 301. A valve 308 is provided on the outer surface of the discharge pipe 307. The bottom end of the discharge pipe 220 is fixedly connected to the top of the crushing box 301. The bottom of the separation box 201 is installed on the top of the sewage mixing processor 1 through an auxiliary rod.

[0028] The overall effect of Embodiment 2 is as follows: the separated solid impurities are transported to the crushing box 301 through the discharge pipe 220. The servo motor 303 is activated, driving the rotating shaft 304 and the crushing blade 305 to rotate, crushing the impurities in the crushing box 301. After crushing, the valve 308 is opened, and the crushed impurities are discharged into the slag receiving frame 302 through the discharge pipe 307 for collection. Simultaneously, the rotating shaft 304 drives the scraper 306 to rotate, pushing the impurities on the bottom surface of the crushing box 301 to the discharge pipe 307 for better discharge. This eliminates the need to discharge the crushed solid impurities back into the filtered wastewater for further treatment, reducing the burden on subsequent treatment units and improving the overall efficiency of wastewater treatment. The collected impurities can be recycled or used for other purposes.

[0029] Working principle: Wastewater is discharged into the separation tank 201 through the inlet pipe 216, and solid-liquid separation is performed through the filter separation plate 217. The separated wastewater enters the wastewater mixing processor 1 through the drain pipe 218 for further processing. The solid impurities separated by filtration are guided to the conical frame 219 through the inclined surface of the filter separation plate 217, and then enter the crushing component 3 through the discharge pipe 220 for crushing. The camera 215 captures real-time images of the impurities on the surface of the filter separation plate 217. Simultaneously, the camera transmits the captured images to an external display via electrical signals. Operators can view the surface of the filter separation plate 217 on the external display. When solid impurities are found to have accumulated on the surface of the filter separation plate 217, wastewater injection is paused, and the forward and reverse motor 203 is activated. The rotation of the output end of the forward and reverse motor 203 drives the lead screw 204 to rotate, which in turn moves the moving block 205. This further moves the slide bar 207 and the moving rod 208 towards the conical frame 219, causing the pusher plate 209 to move and push the accumulated solid impurities on the filter separation plate 217 into the conical frame 219. Then, the output end of the forward and reverse motor 203 rotates in the reverse direction, causing the pusher plate 209 to move in the reverse direction and reset. Wastewater injection continues, and the filtration and separation process is completed. Under the action of the filter separation component 2, impurities on the surface of the filter separation plate 217 can be effectively pushed into the conical frame 219, thereby achieving a cleaning effect and preventing impurities from accumulating on the filter screen surface and affecting the subsequent wastewater separation effect. The servo motor 303 is started, driving the rotating shaft 304 and the crushing blade 305 to rotate, crushing the impurities in the crushing box 301. After crushing, the valve 308 is opened, and the crushed impurities are discharged into the slag receiving frame 302 through the discharge pipe 307 for collection. At the same time, the rotating shaft 304 drives the scraper 306 to rotate, pushing the impurities on the bottom surface of the crushing box 301 to the discharge pipe 307 for better discharge. This eliminates the need to discharge the crushed solid impurities back into the filtered wastewater for further treatment, reducing the burden on subsequent treatment units and improving the overall efficiency of wastewater treatment. The collected impurities can be recycled or used for other purposes.

Their working principles are known technologies. The appropriate model is selected according to actual use.
