Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, and in particular to a wastewater treatment device for urban communities. Background Art

[0002] Urban domestic sewage mainly comes from households, businesses and urban public facilities, and organic matter is the main pollutant in domestic sewage, such as starch, protein, sugar and vegetable oil. Most urban wastewater is discharged into the sewage pipe through the sewer pipe. There are often some large particles of garbage in the kitchen waste and domestic wastewater in the community that are discharged into the pipe through the sewer pipe. Long-term accumulation can easily cause the sewage pipe to be blocked. After the sewage pipe is blocked, it is easy to leak wastewater and make drainage difficult. Therefore, it is best to screen the domestic sewage after it is discharged into the sewer pipe, screen the large particles of garbage in the sewage and treat it through a fixed channel, so that the domestic sewage can be discharged into the sewage pipe, so as not to cause blockage of the sewage pipe.

[0003] Therefore, in public places, such as residential areas, shopping malls, etc., there is an urgent need for an urban community wastewater treatment device between the main sewage pipe and the sewer pipe, which can initially filter out large particles of garbage in the wastewater and reduce the probability of sewage pipe blockage.

[0014] 1. The present invention arranges a baffle assembly, a push plate assembly and a driving assembly on a filter box, uses the driving assembly to drive the baffle assembly to move up and down, and uses the push plate assembly to push the filtered large-particle garbage into a second box on one side, so as to separate sewage from large-particle garbage; during the filtering process, the driving assembly drives the baffle assembly to return to its original position, and during the layer-by-layer filtering process after the sewage enters the filter box, the sewage will not leak out of the filter box, but will only flow downward from the filter screen and flow into the first box at the bottom. One side of the first box is connected to a water outlet pipe, and the sewage can be discharged from the water outlet pipe to the sewer pipe, so that the pipe will not be blocked.

[0015] 2. The present invention sets the baffle assembly into a baffle and chute structure. Under normal circumstances, the baffle completely blocks the filter box, and there is no problem in filtering sewage. When it is necessary to clean the particulate garbage on the filter screen, it is only necessary to drive the baffle to slide into the chute through the driving assembly, and the baffle will rise a certain distance, and a rubber pad is set in the chute to play a sealing role to prevent water leakage. A rubber pad is set at the bottom of the baffle. Under normal circumstances, the bottom of the baffle contacts the filter box, and the rubber pad plays a role in sealing and preventing water seepage.

[0016] 3. The present invention sets the filter screen at the bottom of the filter box to an inclined structure, which is more convenient when cleaning particulate garbage. Small particle garbage can be cleaned directly through a high-pressure water spray gun and directly flushed into the second box, so that the filter screen at the bottom of the filter box can be kept clean.

[0017] 4. The height of the push plate of the present invention is set to be less than or equal to the stroke of the baffle moving up and down. After the driving assembly realizes the up and down movement of the baffle, the push plate can move on the filter screen surface of the filter box, and the baffle does not affect the movement of the push plate.

[0018] 5. The present invention changes the unified treatment mode of urban wastewater into purification based on communities, reduces the flow of wastewater, can reduce the frequency of blockage of urban domestic wastewater pipes, and greatly reduces the workload of pipe dredging. Domestic wastewater is purified by physical filtration and uses gravity seepage to purify water. Compared with traditional urban water purification, the energy consumption is low, the energy and material costs of wastewater treatment are reduced, which is of great significance to the sustainable development of cities. The structure is simple and the complexity of the wastewater purification system is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0027] See attached Figure 1 To Attachment Figure 6 The present invention discloses a wastewater treatment device for urban communities, comprising a first box body 1 connected to a water outlet pipe, a second box body 2 arranged on one side of the first box body 1, a filter box body arranged above the first box body 1, and a water inlet pipe connected to the upper end of the filter box body. Figure 1 A water outlet 101 is provided on the first box body 1, and the water outlet 101 is connected to the water outlet pipe.

[0028] Several layers of filter screens 301 with gradually decreasing filter holes are sequentially arranged from top to bottom in the filter box. The present invention is described by taking four layers of filter screens as an example. Figure 2 Baffle assemblies are arranged in pairs from top to bottom at the positions corresponding to the positions of the filter screen 301 on the front and rear sides of the filter box, and a driving assembly is connected to the baffle assembly. A push plate assembly is arranged on the side of the filter box away from the second box 2 and directly opposite to the baffle assembly. The push plate assembly is arranged vertically and tightly against the upper surface of the filter screen 301. The driving assembly drives the baffle assembly to move up and down a certain distance and the push plate assembly moves along the upper surface of the filter screen 301 toward or away from the second box 2.

[0029] See also Figures 3 to 5 The baffle structure includes baffles 302 slidably connected to the box plates on the left and right sides of the filter box body, and a chute 303 arranged on the lower surface of the filter screen 301 and matched with the baffle 302. The chute 303 and the baffle 302 appear in pairs. The corresponding chute 303 is arranged on the lower surface of the upper filter screen 301, and the corresponding baffle 302 is located below the chute 303. Rubber pads 304 are clamped in the chute 303 and on the lower surface of the baffle 302. The baffle 302 is slidably connected to the chute 303 up and down. When the baffle 302 slides to the bottom, the rubber pad 304 on the lower surface of the baffle 302 plays a sealing role. The lower end of the chute 303 contacts the upper surface of the baffle 302, and the rubber pad 304 inside it plays a sealing role. The chute 303 and the baffle 302 as a whole play the role of the box plate on the front and rear sides of the filter box body, and the sewage entering the filter box body will not leak to the outside from the baffle 302 or the chute 303.

[0030] In addition, the inner diameter of the slide groove 303 matches the size of the baffle 302, and the baffle 302 can slide up and down in the slide groove 303. When it is necessary to clean the garbage on the filter screen 301, it is only necessary to control the baffle 302 to slide into the slide groove 303 to leak the space on both sides of the upper surface of the filter screen 301, and use the push plate assembly to achieve garbage cleaning.

[0031] The four-layer filter screen 301 used in the embodiment of the present invention has three layers of filter screens 301 on the top and a horizontal structure, and the filter screen 301 at the bottom is an inclined structure, which is inclined toward the second box 2. A push plate assembly is arranged on one side of the upper surface of the three layers of filter screens 301 on the top, and no push plate assembly is arranged at a position directly opposite to the upper surface of the filter screen 301 at the bottom of the filter box. A high-pressure water spray gun 305 is arranged on one side of the filter screen 301 at the bottom, see the attached Figure 6 A high-pressure water spray gun 305 is arranged at the bottom of the filter box away from the second box 2, and the nozzle of the high-pressure water spray gun 305 faces the surface of the filter screen 301 at the bottom of the filter box, and the high-pressure water spray gun 305 is connected to the high-pressure water pipe 306. In the process of cleaning garbage by sewage filtration, the baffle 302 is driven upward by the driving component, and the push plate component pushes the garbage on the surface of the filter screen 301 into the second box 2, and the high-pressure water spray gun 305 of the filter screen 301 at the bottom of the filter box is started, and the garbage at the bottom layer is sprayed out of the filter screen 301 into the second box 2 by high pressure.

[0032] See attached Figure 3The push plate assembly includes a push plate 307 and a hydraulic cylinder 308. The telescopic end of the hydraulic cylinder 308 is connected to the push plate 307. The push plate 307 is directly opposite to the baffle 302 on one side, and the width of the push plate 307 is less than or equal to the stroke of the baffle 302 moving up and down. During the upward movement of the baffle 302, the stroke of the baffle 302 is the height of the leak, and the height of the push plate 307 is less than or equal to the stroke of the baffle 302 moving up and down, ensuring that the movement of the push plate 307 is not affected by the baffle 302.

[0033] See attached Figure 1 The driving assembly disclosed in the present invention includes a driving motor 309, a driving gear 310, a driven gear 311, a first driven shaft 312, and a second driven shaft 313. The driving motor 309 is fixed to a box plate on the side of the filter box body, and its output shaft is connected to the driving gear 310. The driven gear 311 is arranged on the first driven shaft 312. The driving gear 310 is meshed with the driven gear 311. Figure 1 It can be seen that the first driven shaft 312 is fixed to the front and rear side panels of the filter box through a number of bearings 320. The driving motor 309 drives the driving gear 310 to rotate, and the driving gear 310 drives the driven gear 311 to rotate, and the driven gear 311 in turn drives the first driven shaft 312 to rotate. A second driven shaft 313 is also rotatably connected to the lower end of the filter box on the same side as the first driven shaft 312 through a bearing 320. The first driven shaft 312 and the second driven shaft 313 are respectively rotatably arranged at the upper and lower ends of a side of the filter box away from the second box 2, and a pair of first vertical chains 314 are used for transmission between the two. The first driven shaft 312 rotates, and the second driven shaft 313 below is driven to rotate through the first vertical chain 314. Transmission wheels are rotatably arranged at the upper and lower ends of the two side panels of the filter box close to the second box 2, see Figure 1 The upper transmission wheel is the first transmission wheel 316, and the lower transmission wheels are the second transmission wheel 317 and the third transmission wheel 318. The third transmission wheel 318 is coaxially arranged with the second transmission wheel 317. The first transmission wheel 316 and the second transmission wheel 317 are driven by the second vertical chain 315. The transmission wheels corresponding to the positions at both ends of the second driven shaft 313 are driven by the transverse chain 319, that is, the third transmission wheel 318 and the second driven shaft 313 are driven by the transverse chain 319. Baffle assemblies are fixed on the two pairs of vertical chains, that is, baffles 302 are fixed on the first vertical chain 314 and the second vertical chain 315 at intervals. There are protruding metal bodies on both sides of the baffle 302, which are connected to the two pairs of vertical chains. The rotation of the vertical chains drives the baffle 302 to move up and down to realize the opening and closing of the box.

[0034] The second box 2 is arranged on the lifting platform 201, and a support plate 202 is arranged on the lifting platform 201, and the support plate 202 is arranged horizontally, and the second box 2 is arranged on the support plate 202. A pair of rolling grooves 203 are arranged on the support plate 202 along its length direction, and a roller 204 is arranged at the bottom of the second box 2, and the roller 204 is arranged in the rolling groove 203. A hanging ring 205 is arranged at one end of the second box 2. After the second box 2 is full of garbage, it is necessary to pull the garbage in the second box to a fixed place for processing. When the structure designed by the present invention is cleaned, the hook ring on the truck can be used to pull the second box 2 to one side, and the roller 204 rolls in the rolling groove 203 until it moves to the truck on one side, and then another second box 2 is pushed from the truck on the other side of the support plate 202 to the designated position of the support plate 202. In the process of cleaning the garbage in the second box 2, the height of the entire support plate 202 and the second box 2 can be adjusted by the lifting platform 201 to adapt it to the height of the truck on one side.

[0035] Working principle:

[0036] The water inlet pipe on the filter box is opened. After the domestic sewage is filtered by the filter box, the sewage is filtered through the layers of filter screens 301 and then falls into the first box 1. The sewage in the first box 1 can be connected to the outlet pipe through the outlet 101 for discharge.

[0037] After the filtering operation, when cleaning the large particles of garbage in the filter box, the driving motor 309 drives the driving gear 310 to rotate, and the driving gear 310 drives the driven gear 311 to rotate, and the driven gear 311 further drives the first driven shaft 312 to rotate. The first driven shaft 312 rotates, and the second driven shaft 313 below is driven to rotate through the first vertical chain 314. The first driven shaft 312 and the second driven shaft 313 rotate through the transverse chain 913 to drive the third transmission wheel 318 to rotate. The third transmission wheel 318 is coaxially arranged with the second transmission wheel 317, so that the third transmission wheel 318 drives the second transmission wheel 317 to rotate, and the second transmission wheel 317 rotates and transmits through the second vertical chain 315, so that the first vertical chain 314 and the second vertical chain 315 simultaneously drive the baffle 302 thereon to move upward or downward. When moving upward, the baffle 302 slides into the chute 303, leaving space on the front and rear sides of the filter box, and the hydraulic cylinder 308 pushes the push plate 307 to move toward the second box 2, so that the large particles of garbage on the filter screen 301 are cleaned out of the filter box, until the garbage is pushed into the second box 2, and the cleaning work is completed. When cleaning garbage, the high-pressure water spray gun 305 on one side of the bottom filter screen 301 is turned on to flush the bottom garbage into the second box 2 through the water flow.

[0038] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention.
