Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a high-efficiency wastewater treatment device. Background Technology

[0002] Wastewater treatment involves using physical, chemical, and biological methods to purify wastewater, reduce pollution, and ultimately achieve wastewater recycling and reuse, thus making full use of water resources.

A rectangular baffle is movably connected to the front outer surface of the wastewater treatment device body, a handle is fixedly connected to the front outer surface of the rectangular baffle, and a rectangular material frame is fixedly connected to the rear outer surface of the rectangular baffle. This high-efficiency wastewater treatment equipment, unlike traditional wastewater treatment equipment, can filter solid impurities in wastewater during use, preventing damage to the inner wall of the equipment caused by solid impurities colliding with it during wastewater treatment, thus extending the service life of the wastewater treatment equipment.

[0004] The aforementioned patent uses a filter screen to filter impurities in wastewater, preventing solid impurities from damaging the inner wall of the wastewater treatment equipment. However, since the device uses a fixed filter screen to filter wastewater, solid impurities in the wastewater accumulate on the surface of the filter screen. After long-term use, the filter screen becomes clogged, thus affecting the efficiency of the filter screen in filtering wastewater. Utility Model Content

[0005] Therefore, it is necessary to provide a high-efficiency wastewater treatment device to address the problem that solid impurities in wastewater accumulate on the surface of the filter screen, causing filter clogging and affecting the filter's efficiency.

[0006] A high-efficiency wastewater treatment device includes: a treatment tank, in which a filter screen for filtering solid impurities in wastewater is movably arranged, and a slag-removing mechanism for removing solid impurities accumulated on the surface of the filter screen is arranged above the filter screen.

[0007] The slag-removing mechanism includes a slag-removing plate, the bottom end of which contacts the surface of the filter screen, and the bottom end of the slag-removing plate in contact with the filter screen is in the shape of a comb.

[0008] The slag removal mechanism also includes a drive component for driving the slag removal plate to reciprocate along the surface of the filter screen.

[0009] Below the filter screen is a sludge-pushing mechanism for cleaning the sludge that settles on the bottom surface of the treatment tank.

[0010] In one embodiment, the drive assembly includes a threaded rod and a slider. The inner wall of the processing box is symmetrically provided with mounting shells. The threaded rods are rotatably disposed inside the mounting shells. The slider is threadedly sleeved on the outside of the threaded rods. The bottom end of the slider passes through a through groove opened on the bottom surface of the mounting shell and is fixedly connected to the top ends of both sides of the slag removal plate.

[0011] In one embodiment, the drive assembly further includes a worm gear and a worm. The ends of the two sets of threaded rods that pass through the side wall of the processing box on the same side are connected to the worm gear. The worm gear is meshed above the worm gear. The two sets of worms are connected by a connecting rod. One end of the connecting rod passes through one side wall of the housing and is connected to a rotating handle. The other end of the connecting rod is rotatably mounted on the inner wall of the housing.

[0012] In one embodiment, the outer sidewall of the slider is in contact with and fits against the inner wall of the mounting housing, and the outer sidewall of the housing is rotatably provided with an inspection door.

[0013] In one embodiment, the sludge pushing mechanism includes an electric push rod, the working end of which penetrates through the side wall of the treatment box and is connected to a scraper. The electric push rod is fixedly installed on the side wall of a bracket, and the bracket is fixedly installed on the outer side wall of the treatment box.

[0014] In one embodiment, the inner bottom surface of the treatment tank is set as an inclined surface, and the lowest end of the inclined surface is at the same horizontal plane as the inner bottom surface of the water outlet pipe that runs through the side wall of the treatment tank. The bottom end of the scraper is slidably connected to the inner bottom surface of the inclined surface of the treatment tank.

[0015] In one embodiment, the side wall of the treatment tank has a slot inside the outlet pipe, a filter plate is inserted into the slot, the outer side wall of the filter plate is bolted to the outer side wall of the treatment tank, and the inner wall of the treatment tank has an installation groove, into which the filter screen is inserted.

[0016] In one embodiment, guide plates are symmetrically arranged on both sides of the inner wall of the treatment box above the filter screen. The bottom end of the guide plate does not contact the top surface of the slag removal plate. The top surface of the treatment box is made of transparent material, and a water inlet pipe is connected through the top surface of the treatment box.

[0017] Beneficial effects

[0018] 1. A movable slider is installed above the filter screen to move the solid impurities accumulated on the filter screen surface. The worker manually turns the handle to drive two sets of worm gears connected by connecting rods to rotate synchronously, thereby driving two sets of threaded rods to rotate simultaneously. This drives the slider outside the threaded rods to slide inside the mounting housing, further enabling the slider to move the solid impurities accumulated on the filter screen surface along the filter screen surface, thus preventing solid impurities from accumulating and clogging the filter screen, which would affect the wastewater filtration efficiency.

[0019] 2. At the same time, the bottom surface of the treatment box is set to be inclined, and a movable scraper is set above the bottom surface of the treatment box to scrape and clean the sludge settled on the bottom surface of the treatment box, ensuring the cleanliness of the inside of the treatment box.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The following is combined with Figures 1-5 This invention describes a highly efficient wastewater treatment device.

[0030] In one embodiment, a high-efficiency wastewater treatment device includes: a treatment tank 100, in which a filter screen 103 for filtering solid impurities in wastewater is movably disposed inside, and a slag-removing mechanism 300 for removing solid impurities accumulated on the surface of the filter screen 103 is disposed above the filter screen 103.

[0031] Below the filter screen 103 is a sludge pushing mechanism 200 for cleaning the sludge that settles on the bottom surface of the treatment box 100.

[0032] like Figure 2 and Figure 3 As shown, the slag removal mechanism 300 includes a slag removal plate 304, the bottom end of which contacts the surface of the filter screen 103, and the bottom end of the slag removal plate 304 that contacts the filter screen 103 is in the shape of a comb.

[0033] The slag removal mechanism 300 also includes a drive assembly for driving the slag removal plate 304 to reciprocate along the surface of the filter screen 103.

[0034] In this embodiment, a drive assembly is configured to drive the slag-removing plate 304 to reciprocate above the filter screen 103, thereby removing the solid impurities accumulated on the surface of the filter screen 103 and preventing solid impurities from accumulating on the surface of the filter screen 103 and affecting the filter screen 103's ability to filter wastewater, thus affecting the filter screen 103's efficiency in filtering wastewater.

[0035] like Figure 3 As shown, the drive assembly includes a threaded rod 302 and a slider 303. The inner wall of the processing box 100 is symmetrically provided with mounting shells 301. The threaded rods 302 are rotatably disposed inside the mounting shells 301. The slider 303 is threadedly sleeved on the outside of the threaded rods 302. The bottom end of the slider 303 passes through the through groove 305 opened on the bottom surface of the mounting shell 301 and is fixedly connected to the top ends of both sides of the slag removal plate 304.

[0036] The drive assembly also includes a worm gear 309 and a worm 310. The ends of the two sets of threaded rods 302 that penetrate the side wall of the processing box 100 on the same side are connected to the worm gear 309. The worm gear 310 is meshed above the worm gear 309. The two sets of worm gears 310 are connected by a connecting rod 311. One end of the connecting rod 311 penetrates one side wall of the housing 307 and is connected to the rotating handle 306. The other end of the connecting rod 311 is rotatably mounted on the inner wall of the housing 307.

[0037] In this embodiment, two sets of mounting shells 301 are symmetrically arranged on the inner walls of both sides of the treatment box 100, and threaded rods 302 are rotatably arranged inside the two sets of mounting shells 301. At the same time, sliders 303 are threadedly sleeved on the outer arc surfaces of the two sets of threaded rods 302. The outer side wall of the slider 303 is tightly fitted with the inner wall of the mounting shell 301. Driven by the rotational force of the threaded rods 302, the slider 303 slides along the inner wall of the mounting shell 301, which further drives the slider 303 below to slide, thus moving the solid impurities accumulated on the surface of the filter screen 103 and preventing the solid impurities from clogging the filter screen 103 and affecting the filter screen 103's ability to filter wastewater.

[0038] Meanwhile, the ends of the two sets of threaded rods 302 on the same side penetrate the side wall of the processing box 100 and are connected to the worm gear 309. The worm gear 309 is meshed with a worm 310 above it. The two sets of worm gears 310 are connected by a connecting rod 311. One end of the connecting rod 311 penetrates the side wall of the outer shell 307 and is connected to the rotating handle 306. The other end of the connecting rod 311 is rotatably set on the inner wall of the outer shell 307. The worker can drive the two sets of worm gears 310 to rotate synchronously by rotating the rotating handle 306, thereby driving the two sets of worm gears 309 to drive the threaded rods 302 to rotate synchronously, thereby driving the slag-removing plate 304 and removing impurities on the surface of the filter screen 103.

[0039] like Figure 1 As shown, the outer wall of the slider 303 is in contact with and fits against the inner wall of the mounting shell 301, and the outer side wall of the outer shell 307 is rotatably provided with an inspection door 308.

[0040] In this embodiment, the outer wall of the slider 303 is made to contact and fit with the inner wall of the mounting shell 301 to ensure that the slider 303 slides inside the mounting shell 301 under the drive of the rotational force of the threaded rod 302, thereby restricting the slider 303 from rotating according to the rotation of the threaded rod 302. Furthermore, an inspection door 308 is provided on the outer side wall of the outer shell 307 to facilitate workers to regularly inspect and maintain the internal worm gear 309 and worm 310.

[0041] like Figure 4As shown, the sludge pushing mechanism 200 includes an electric push rod 202. The working end of the electric push rod 202 passes through the side wall of the treatment box 100 and is connected to the scraper 203. The electric push rod 202 is fixedly installed on the side wall of the bracket 201, and the bracket 201 is fixedly installed on the outer side wall of the treatment box 100.

[0042] The inner bottom surface of the treatment tank 100 is set as an inclined surface. The lowest end of the inclined surface is at the same level as the inner bottom surface of the water outlet pipe 102 that is provided through the side wall of the treatment tank 100. The bottom end of the scraper 203 is slidably connected to the inner bottom surface of the inclined surface of the treatment tank 100.

[0043] In this embodiment, the inner bottom surface of the treatment tank 100 is set as an inclined surface, and a scraper 203 is provided above the inclined surface. The working end of the electric push rod 202 extends to drive the scraper 203 to slide along the inclined surface of the inner bottom surface of the treatment tank 100, thereby scraping and cleaning the sludge deposited on the inner bottom surface of the treatment tank 100 and discharging it through the water outlet pipe 102, thus avoiding the accumulation of sludge on the inner bottom surface of the treatment tank 100 and affecting subsequent wastewater treatment.

[0044] like Figure 4 and Figure 5 As shown, a slot 204 is provided on the side wall of the treatment box 100 inside the outlet pipe 102. A filter plate 205 is inserted into the slot 204. The outer side wall of the filter plate 205 is installed on the outer side wall of the treatment box 100 by bolts. An installation groove 105 is provided on the inner wall of the treatment box 100. A filter screen 103 is inserted into the installation groove 105.

[0045] In this embodiment, a slot 204 is provided inside the side wall of the treatment tank 100 that is connected to the outlet pipe 102. A detachable filter plate 205 is provided inside the slot 204. The pore size inside the filter plate 205 is smaller than the pore size inside the filter screen 103. The wastewater after the initial filtration by the filter screen 103 is filtered through the filter plate 205 for secondary filtration. When it is necessary to clean the sludge on the bottom surface of the treatment tank 100, the filter plate 205 is removed, and the electric push rod 202 is activated to push the scraper 203 to slide along the inclined surface of the bottom surface of the treatment tank 100, pushing the sludge into the outlet pipe 102 and discharging it through the outlet pipe 102. For the sludge inside the slot 204, the worker cleans it with a high-pressure water gun.

[0046] like Figure 2 As shown, guide plates 104 are symmetrically arranged on both sides of the inner wall of the treatment box 100 above the filter screen 103. The bottom end of the guide plate 104 does not contact the top surface of the slag removal plate 304. The top surface of the treatment box 100 is made of transparent material, and the top surface of the treatment box 100 is connected to the water inlet pipe 101.

[0047] In this embodiment, the top surface of the treatment box 100 is made of a transparent material, which makes it easy for workers to observe the solid impurities on the surface of the internal filter screen 103 and to periodically remove and clean the filter screen 103. At the same time, guide plates 104 are symmetrically arranged above the filter screen 103 on the inner wall of the treatment box 100. The guide plates 104 guide the wastewater entering the treatment box 100 to avoid impurities in the wastewater from damaging the mounting shell 301 and to protect the mounting shells 301 on both sides.

[0048] Working principle: By connecting the external pipe to the inlet pipe 101, external wastewater enters the treatment tank 100 through the inlet pipe 101. The wastewater is initially filtered through the filter screen 103. The guide plates 104 on both sides guide the wastewater to prevent impurities in the wastewater from falling onto the mounting shell 301 and causing damage to it. By manually turning the handle 306 in both directions, the two sets of worm gears 310 are driven to rotate synchronously, which in turn drives the two sets of worm wheels 309 to drive the threaded rod 302 to rotate synchronously. This drives the slag-removing plate 304 to move the accumulated solid impurities on the surface of the filter screen 103, preventing the impurities from clogging the filter screen 103 and affecting the filtration of wastewater by the filter screen 103.

[0049] The filtered wastewater is discharged through the outlet pipe 102. The side wall of the treatment tank 100 is provided with a slot 204 inside the outlet pipe 102. A removable filter plate 205 is installed inside the slot 204 to perform secondary filtration on the wastewater after it has been filtered by the filter screen 103, so as to ensure the quality of the wastewater discharged from the outlet pipe 102.

[0050] After the wastewater treatment is completed, the worker starts the electric actuator 202, which drives the scraper 203 to push the sludge on the bottom surface of the treatment tank 100, disassembles the filter plate 205, and the sludge enters the interior of the outlet pipe 102 through the slot 204 and is discharged through the outlet pipe 102. The worker can use an external high-pressure water gun to wash and clean the sludge inside the slot 204.

[0051] It should be noted that the electric actuator 202 mentioned above is a device with relatively mature existing technology. The specific model can be selected according to actual needs, and the electric actuator 202 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation, and will not be elaborated here.

[0052] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
