[0002] Underground sewage treatment equipment can treat domestic sewage. This equipment includes a primary sedimentation tank, a contact oxidation tank, a secondary sedimentation tank, and a disinfection tank. During primary treatment, the incoming sewage needs to be filtered, often using a screen filter. Impurities are filtered out by the screen, thus reducing the burden on subsequent sewage treatment.

[0003] In related technologies, such as the buried integrated sewage treatment equipment disclosed in CN104556353B, a molded container shell and contents are included. The molded container shell includes two interconnected filter media chambers, I and II. Each of the filter media chambers I and II is composed of sequentially connected filter media zones, which are filled with different contents to remove different pollutants. Filter media chamber I includes sequentially connected filter media zones I, II, and III. This equipment can filter sewage.

[0004] Untreated wastewater contains a large number of large particles. If traditional filters are used for filtration, impurities will quickly accumulate on the surface of the filters, requiring frequent replacement of the filters.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] like Figures 1-9 As shown, an embodiment of the present invention provides a buried integrated sewage treatment equipment, comprising:

[0036] Processing component 1 includes a processing housing 101, a filter element is provided inside the processing housing 101, a drain pipe 108 is installed on the right side of the processing housing 101, and a mating block 106 is fixedly connected to the left side of the processing housing 101. The upper part of the mating block 106 is in contact with the circulating filter screen 302, and the upper part of the mating block 106 is provided with an inclined surface for guiding impurities to be discharged.

[0037] refer to Figure 1The treatment housing 101 is a rectangular housing used to hold the treated wastewater. The mating block 106 can contact the lower surface of the circulating filter screen 302. When the circulating filter screen 302 is pulled up and released by the lubricating wheel 406, it will collide with the mating block 106, further shaking off the impurities remaining on the circulating filter screen 302, ensuring that the subsequent filtration function of the circulating filter screen 302 can be used normally. The inclined surface on the upper part of the mating block 106 can guide the shaken impurities to fall, avoiding impurities from remaining on the upper surface of the mating block 106.

[0038] The filter element includes a primary filter element 103, a secondary filter element 104, and a tertiary filter element 105. The upper part of the treatment housing 101 is detachably connected to a disassembly cover 107. The bottom surface of the treatment housing 101 is provided with a water delivery slope 102 and a stepped surface from left to right. The primary filter element 103, the secondary filter element 104, and the tertiary filter element 105 are located on the stepped surface.

[0039] refer to Figure 2 After the sewage enters the treatment shell 101, the primary filter element 103, the secondary filter element 104 and the tertiary filter element 105 perform multi-stage filtration on the sewage. The primary filter element 103 can be made of quartz sand filter media, which has a rough surface and high mechanical strength, and can effectively intercept suspended solids and colloidal substances in the sewage, thereby removing impurities from the water.

[0040] The secondary filter element 104 can use anthracite filter media, which has a rough and porous surface with high porosity, enabling it to efficiently adsorb organic matter and some heavy metals, thereby improving its interception capacity and filtration speed.

[0041] The 105 three-stage filter cartridge can use manganese sand filter media and activated carbon filter media. The manganese sand filter media contains manganese dioxide, which uses catalytic oxidation to remove harmful substances such as iron, manganese, and arsenic from the water, thereby improving the water quality standard. The activated carbon filter media has a well-developed pore structure and a large specific surface area, which purifies the water quality through physical adsorption and chemical reduction, and deeply removes organic matter, residual chlorine, odors and toxic substances.

[0042] To achieve multi-stage treatment of wastewater, in other embodiments, the primary filter element 103, secondary filter element 104, and tertiary filter element 105 can also be made of other filter materials, depending on the actual treatment requirements. The inclined surface is used to guide the accumulation of impurities in the wastewater, which is convenient for later cleaning. The stepped surface is used to intercept impurities that settle at the bottom, but it can also be omitted to ensure that the wastewater can flow out fully. This can be selected at your discretion.

[0043] Water inlet assembly 2 is located on the left side of the treatment housing 101 and is used for sewage to enter. Water inlet assembly 2 includes a water inlet pipe 201 fixedly installed on the treatment housing 101. The lower end of the water inlet pipe 201 is detachably connected to a dispersion housing 202. The lower part of the dispersion housing 202 is provided with a dispersion port 203.

[0044] refer to Figure 3 The inlet pipe 201 is used to guide sewage into the treatment housing 101. After the sewage enters the dispersion housing 202, it is discharged from the dispersion port 203, so that the sewage is evenly dispersed on the circulating filter screen 302, avoiding sewage concentration and causing the filtering function of the circulating filter screen 302 to fail, thus ensuring good filtering function.

[0045] The circulation component 3 is located below the water inlet component 2 and is used to circulate and discharge the filtered impurities.

[0046] The circulation assembly 3 includes a circulation frame 303 fixedly installed on the processing housing 101. A self-rotating component 308 is rotatably installed on the circulation frame 303. Circulation chains 301 are symmetrically connected to the self-rotating component 308. A circulation filter screen 302 is detachably connected between the two circulation chains 301. A driving component is installed on the left circulation frame 303. The driving component is used to drive the self-rotating component 308 to rotate.

[0047] refer to Figure 4 During the circulating filtration operation, the circulating chain 301 can synchronously drive the circulating filter screen 302 to move. The circulating filter screen 302 can be removed from the circulating chain 301. The removal method can be the commonly used bolt and nut connection or the snap-on connection, which can be selected according to the needs. The circulating filter screen 302 can be made of metal mesh.

[0048] The driving component includes a drive motor 307 fixedly mounted on the circulation frame 303. An upper pulley 306 is fixedly connected to the output end of the drive motor 307. A lower pulley 304 is provided below the upper pulley 306. A belt 305 is connected between the upper pulley 306 and the lower pulley 304. The lower pulley 304 is fixedly connected to the left drive shaft 3081.

[0049] refer to Figure 4 During operation, the drive motor 307 operates under the control of the external power supply and controller, causing the upper pulley 306 to rotate. The upper pulley 306, through the belt 305, drives the lower pulley 304 to rotate, which in turn drives the left drive shaft 3081 to rotate. The left drive shaft 3081 drives the sprocket 3082 to rotate, and the sprocket 3082 drives the circulating chain 301 to move, thereby realizing the driving function. The drive component can also adopt a chain drive to avoid pulley slippage.

[0050] The self-rotating component 308 includes a drive shaft 3081, on which sprockets 3082 are symmetrically and fixedly connected, and the sprockets 3082 are in a transmission cooperation with the circulating chain 301.

[0051] refer to Figure 5 The self-rotating component 308 is used to drive the movement of the circulating chain 301, and the gap between the two sprockets 3082 can be used to provide space for the vibration of the circulating filter screen 302.

[0052] Lubrication component 4 is located outside the circulation component 3 and is used to apply lubricating oil to the circulation chain 301. The lubrication component 4 includes a cam 401 fixedly mounted on the drive shaft 3081, a support shaft 404 fixedly mounted on the circulation frame 303, a rocker arm 403 movably connected to the support shaft 404, a contact head 402 fixedly connected to one end of the rocker arm 403, the contact head 402 and the cam 401 being positioned opposite each other, a holding box 405 fixedly connected to the other end of the rocker arm 403, an oil holding groove 4051 provided inside the holding box 405, a lubrication wheel 406 rotatably connected inside the holding box 405, an oil holding cavity 4061 evenly provided around the circumference of the lubrication wheel 406, the lower part of the lubrication wheel 406 being located inside the oil holding groove 4051, and a cleaning brush 407 fixedly connected to one end of the rocker arm 403 near the lubrication wheel 406.

[0053] refer to Figure 6 , Figure 8 , Figure 9 During lubrication, due to the configuration of the lubrication wheel 406, oil tank 4051, and container 405, their weight is greater than that of the contact head 402. When the contact head 402 is not pushed by the cam 401, the end of the container 405 will move away from the circulating chain 301. At this time, it is in an unlubricated state. The cleaning brush 407 comes into contact with the surface of the circulating chain 301, thereby achieving the cleaning function of the circulating chain 301 and preventing dust from adhering to the circulating chain 301.

[0054] When the protrusion of the cam 401 pushes the contact head 402, the container 405 can be tilted up by lever principle. The lubrication wheel 406 inside the container 405 will contact the circulating chain 301 and tighten the circulating chain 301. The movement of the circulating chain 301 can drive the lubrication wheel 406 to rotate. The lubrication wheel 406 can apply lubricating oil to the circulating chain 301 by using its own surface and oil cavity 4061. When the container 405 returns to its original position, the tensioned circulating chain 301 will fall and collide with the mating block 106. The circulating filter 302 connected to the circulating chain 301 will move synchronously, thereby helping to shake off the impurities adhering to the circulating filter 302. Since the vibrating part of the circulating filter 302 is at the bottom, the impurities on the circulating filter 302 are easier to fall off.

[0055] When maintenance is required, the rocker arm 403 can be pulled outward, and the rocker arm 403 slides on the support shaft 404, thereby causing the lubrication wheel 406 to move outward synchronously. At this time, lubricating oil can be added into the oil tank 4051 for easy maintenance. At this time, the contact head 402 is misaligned with the cam 401, and the cleaning brush 407 can be used to continuously clean the circulating chain 301.

[0056] A striking component 5 is located within the circulation component 3 and is used to periodically strike the left side of the circulation filter 302. The striking component 5 includes a connecting shaft 504 rotatably mounted on the circulation frame 303 and a support member 508 fixedly mounted on the circulation frame 303. One end of the connecting shaft 504 is fixedly connected to a drive wheel 505, and a connecting arm 506 is rotatably connected to the drive wheel 505. A sliding arm 507 is rotatably connected to the end of the connecting arm 506 away from the drive wheel 505, and a striking rod 510 is fixedly connected to the other end of the sliding arm 507 away from the connecting arm 506. A groove 509 is provided inside the sliding arm 507, and the support member 508 passes through the groove 509, with the support member 508 slidingly engaging with the groove 509. The drive shaft 3081 on the same side drives the connecting shaft 504 to rotate via a transmission component.

[0057] refer to Figure 7 During the striking operation, the drive shaft 3081 drives the connecting shaft 504 to rotate through the transmission component, which in turn drives the drive wheel 505 to rotate. The drive wheel 505 drives the connecting arm 506 to move, and the connecting arm 506 drives the sliding arm 507 to reciprocate. The sliding arm 507 drives the striking rod 510 to periodically strike the circulating filter screen 302. The impurities filtered out on the circulating filter screen 302 will be shaken off. The support member 508 passes through the slide groove 509, which can limit the movement trajectory of the sliding arm 507.

[0058] The striking rod 510 can be a single rod that can fully contact the inner surface of the circulating filter screen 302. In other embodiments, a protrusion can be added to the striking rod 510, and the circulating filter screen 302 will be fully pushed up by the protrusion, thereby ensuring that the impurities on the circulating filter screen 302 can be fully shaken off.

[0059] The transmission component includes a large pulley 501 fixedly mounted on the same side drive shaft 3081, a small pulley 503 fixedly mounted on the other end of the connecting shaft 504, and a second belt 502 provided between the large pulley 501 and the small pulley 503.

[0060] refer to Figure 7 During transmission operation, the drive shaft 3081 can drive the large pulley 501, which in turn drives the small pulley 503 to rotate via the second belt 502. The small pulley 503 can drive the connecting shaft 504 to rotate. By utilizing the transmission ratio between the large pulley 501 and the small pulley 503, it can be ensured that the striking rod 510 can fully collide with and contact the circulating filter screen 302.

[0061] Working principle: Drive motor 307 works under the action of external power supply and controller, driving upper pulley 306 to rotate. Upper pulley 306 drives lower pulley 304 to rotate via belt 305, thereby driving left drive shaft 3081 to rotate. Left drive shaft 3081 drives sprocket 3082 to rotate, and sprocket 3082 drives circulating chain 301 to move.

[0062] The inlet pipe 201 is used to guide the sewage into the treatment shell 101. After the sewage enters the dispersion shell 202, it is discharged from the dispersion port 203, so that the sewage is evenly dispersed onto the circulating filter screen 302. The circulating filter screen 302 will filter out the impurities in the sewage.

[0063] The drive shaft 3081 drives the connecting shaft 504 to rotate through the transmission component, thereby driving the drive wheel 505 to rotate. The drive wheel 505 drives the connecting arm 506 to move. The connecting arm 506 drives the sliding arm 507 to reciprocate. The sliding arm 507 drives the striking rod 510 to periodically strike the circulating filter screen 302, and the impurities filtered on the circulating filter screen 302 will be shaken off.

[0064] When the protrusion of the cam 401 pushes the contact head 402, the container 405 can be tilted up by lever principle. The lubrication wheel 406 inside the container 405 will contact the circulating chain 301 and tighten the circulating chain 301. The movement of the circulating chain 301 can drive the lubrication wheel 406 to rotate. The lubrication wheel 406 can apply lubricating oil to the circulating chain 301 by using its own surface and oil cavity 4061. When the container 405 returns to its original position, the tensioned circulating chain 301 will fall and collide with the mating block 106. The circulating filter screen 302 connected to the circulating chain 301 will move synchronously, thereby helping to shake off the impurities adhering to the circulating filter screen 302.

[0065] The filtered wastewater then undergoes multi-stage filtration treatment through primary filter element 103, secondary filter element 104, and tertiary filter element 105, and the treated water is discharged from drain pipe 108.

[0066] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
