Description

Technical Field

[0001] This invention relates to the field of wastewater treatment equipment technology, specifically a method for installing wastewater treatment equipment. Background Technology

[0002] Wastewater treatment equipment mainly includes pretreatment devices, biological treatment devices, and effluent systems. By filtering and intercepting wastewater, heavier solid particles are removed. The wastewater then enters a sedimentation tank for static settling and pretreatment, where solid particles are separated by gravity sedimentation. Subsequently, microorganisms in the wastewater are separated using membrane separation. After treatment by multiple devices, the wastewater meets discharge standards and is then discharged for recycling. The installation method between the various devices usually involves assembling each device and connecting them through pipelines. The positions of each treatment device are adjusted to accommodate the pipeline connections between the devices, ensuring a tight seal during installation.

[0003] However, existing sewage treatment equipment is inconvenient to adjust. When installing and connecting to the next treatment unit, the position needs to be adjusted. The unit itself is heavy, and it is not easy to keep it stable when lifted and moved by a crane. This can easily cause misalignment in the pipe connections between sewage treatment equipment, making pipe connection between equipment difficult. In addition, each device of the sewage treatment equipment needs to be cleaned regularly to reduce biological residues and corrosion on each treatment device during sewage treatment, and to ensure sewage treatment efficiency and effluent quality. However, due to the difficulty in connecting the pipes between sewage treatment equipment and the relatively small space inside the equipment, it is generally not disassembled for cleaning. Only the top of the equipment is flushed with water at a certain pressure. Because the flushing distance is far and it is not easy to flush the corners inside the equipment, the equipment is easily not cleaned completely. Summary of the Invention

[0004] The present invention provides an installation method for sewage treatment equipment, which overcomes the shortcomings described in the background art.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] An installation method for sewage treatment equipment, wherein adjacent sewage treatment equipment are connected by a connecting assembly, the connecting assembly having a fixed pipe, a movable sleeve, a telescopic structure, a docking plate, and a locking plate, the telescopic structure having its left and right sides respectively connected to the sides of the movable sleeve and the fixed pipe, the docking plate being disposed at the outer end of the movable sleeve, and the locking plate slidingly engaging with the inner side of the docking plate, the fixed pipe being connected to the drain pipe of the sewage treatment equipment via a pipe, the movable sleeve pulling the telescopic structure to extend it and aligning the docking plate with the access end of the adjacent sewage treatment equipment, the docking plate and the fixed pipe each having a connecting flange, and being fixedly connected by reinforcing bolts;

[0007] The telescopic structure comprises a rubber ring, an inner tube, an outer tube, rubber strips, and an arc-shaped plate. The rubber strips are evenly distributed inside the inner tube. Three annular structures are provided between the inner side of the outer tube and the outer side of the inner tube. The annular structures are composed of rubber rings and arc-shaped plates, with the arc-shaped plates positioned on both the inner and outer sides of the rubber rings. The inner side of the outer tube is inclined. The inner tube expands elastically outward through the rubber strips, and the arc-shaped plates slide and compress on the inner and outer sides of the outer tube. When the inner tube moves, it squeezes the arc-shaped plates, causing them to slide on the inclined surface of the outer tube, thus achieving a seal through elastic deformation.

[0008] Based on the connection between adjacent wastewater treatment devices via connecting components, a wastewater treatment device installation method is described, with the following specific installation steps:

[0009] S1: Connect the fixed pipe to the side outlet end of the equipment body through a flange, and manually pull the movable sleeve to put the elastic support structure of the telescopic structure in a stretched state.

[0010] S2: When the telescopic structure is stretched, the inner tube squeezes the arc plate and makes the arc plate slide in an inclined position inside the outer tube, thereby the arc plate compresses the rubber ring and seals the gap between the outer tube and the inner tube under the elastic expansion of the inner tube.

[0011] S3: After the telescopic structure is stretched, rotate the movable sleeve and the telescopic structure with the fixed pipe as the center, and adjust the stretching length of the telescopic structure so that the movable sleeve is aligned with the inlet end of the adjacent sewage treatment equipment.

[0012] S4: Thus, the docking plate corresponds to the outer periphery of the inlet end of the adjacent sewage treatment equipment, and the locking plate slides into the docking plate on the outside of the inlet end to make a staggered connection between the inlet ends of the adjacent sewage treatment equipment.

[0013] A wastewater treatment device is applied to the above-mentioned installation method of a wastewater treatment device. The wastewater treatment device includes a connecting component, a device body, a blower, a stair frame, a base, and a pump station. The blower and the stair frame are respectively arranged on the left and right sides of the device body. The connecting component is arranged at the outlet end of the side of the device body. The device body is fixed to the surface of the base. The pump station is installed on the upper surface of the device body.

[0014] The main body of the equipment includes a cleaning mechanism, a treatment pool, a housing, a drain pipe, and a water inlet pipe. There are four treatment pools, symmetrically distributed inside the housing. The water inlet pipe and drain pipe are respectively located on the left and right sides of the housing, at the left inlet end and the right outlet end of the treatment pool. The cleaning mechanism is located on the upper part of the housing and is correspondingly distributed on the upper part of the treatment pool. The cleaning mechanism is connected to an external power line and a water pipe connector. Power is transmitted through the power line to drive the cleaning mechanism to extend and retract, so that the lower end of the cleaning mechanism moves downward along the inner wall of the treatment pool and rotates, so that the lower end of the cleaning mechanism washes along the bottom of the treatment pool.

[0015] A preferred technical solution: The cleaning mechanism includes a motor, a processor, a first telescopic rod, a first hydraulic actuator, a second hydraulic actuator, and a flushing mechanism. The output end of the motor is equipped with a first hydraulic actuator, which drives the first hydraulic actuator to rotate. The processor is located outside the first hydraulic actuator and is electrically connected to the flushing mechanism, the second hydraulic actuator, and the first hydraulic actuator. The processor drives the first telescopic rod at the output end of the first hydraulic actuator to extend and retract downwards, and causes the second hydraulic actuator at the lower end of the first telescopic rod to drive the flushing mechanism to rotate. The flushing mechanism extends and retracts outwards and moves up and down against the inner wall of the treatment tank.

[0016] A preferred technical solution: The rinsing mechanism includes a track bar, a rotating plate, a scraper structure, a second telescopic rod, and a third hydraulic actuator. The second telescopic rod is located at the output end of the third hydraulic actuator, and the third hydraulic actuator is located at the outer end of the rotating plate. The rotating plate is equipped with a screw. The output end of the second hydraulic actuator drives the screw inside the rotating plate to move, and causes the rotating plate to rotate at the lower end of the second hydraulic actuator. The processor's electrical signal drives the second telescopic rod at the output end of the third hydraulic actuator to extend and retract, and causes the scraper structure to extend outward in a straight line along the track bar.

[0017] A preferred technical solution: The scraper structure includes a water supply pipe, a water inlet plate, a drain connector, a flushing head, a friction strip, and a main body. The water supply pipe is located at the upper end of the drain connector and is connected to a water pipe connector. The drain connector is arranged in a straight line on the inner side of the main body, and the main body extends in a straight line via a track. The water inlet plate is located on the side of the drain connector. The flushing head is inclined at 30° and located at the outer end of the water inlet plate. The friction strip is located at the outer end of the main body and abuts against the inner wall of the treatment tank. The friction strip scrapes against the inner wall of the treatment tank by the contraction of the first telescopic rod. When the rotating plate rotates, the friction strip abuts against the bottom of the treatment tank, and the first telescopic rod retracts upward when the rotating plate rotates, causing the flushing head and the friction strip to perform a "concave" shaped scraping motion along the inner wall of the treatment tank to the bottom.

[0018] A preferred technical solution: A spring rod and a sleeve are provided between adjacent drainage joints. The sleeve has inner and outer tubes that slide against each other. The spring rod is located at the top of the inner tube of the sleeve and is connected to the side of the adjacent drainage joint. When the drainage joint extends with the main body, the inner and outer tubes of the sleeve slide against each other and elastically press against the adjacent drainage joint through the spring rod.

[0019] A preferred technical solution: The rinsing head is provided with a spray plate and an opening groove. The opening groove is located inside the spray plate, and both the upper and lower sides of the opening groove are open. There is a height difference between adjacent spray plates.

[0020] Compared with existing technologies, this technical solution has the following advantages:

[0021] In this invention, when connecting and installing wastewater treatment equipment, a fixed pipe and a movable sleeve are used to connect the ends of the two wastewater treatment devices. When there is a misalignment between the wastewater treatment devices, the movable sleeve is manually pulled to extend the telescopic structure connecting the fixed pipe and the movable sleeve. When there is a height difference at the inlet end, the movable sleeve rotates around the fixed pipe, allowing the connecting plate at the outer end of the movable sleeve to move to the side of the inlet end of the wastewater treatment device. The inlet end of the wastewater treatment device is then closed by a locking plate. This allows for the connection and installation of adjacent wastewater treatment devices even when they are misaligned, avoiding the difficulty of installation when the devices are misaligned.

[0022] In this invention, when the outer end of the rinsing mechanism extends and retracts, the two third hydraulic actuators on the rinsing mechanism are simultaneously controlled by the processor, causing the second telescopic rod at the output end of the third hydraulic actuator to extend outward toward the scraper structure and abut against the inner wall of the treatment tank. Thus, the "L" shape at both ends of the scraper structure causes the corners of the inner wall of the treatment tank to be scraped by the cleaning mechanism during rotation. After the scraping is completed, the rinsing head generates an inclined water flow to rinse the inner wall of the treatment tank. When the scraper structure rotates to the bottom of the treatment tank, the rinsing and scraping of the inner wall of the treatment tank to the bottom by the outer end of the rinsing mechanism is a concave movement. By performing concave movement scraping on the four sides and bottom of the inner wall of the treatment tank by the rinsing mechanism, the corners of the inner wall of the treatment tank are effectively scraped, avoiding the corners of the treatment tank from being easily uncleaned.

Detailed Implementation

[0033] like Figures 1 to 8 As shown, this invention proposes an installation method for sewage treatment equipment. Adjacent sewage treatment equipment is connected via a connecting assembly 1. The connecting assembly 1 includes a fixed pipe 11, a movable sleeve 12, a telescopic structure 13, a docking plate 14, and a locking plate 15. The telescopic structure 13 is connected to the sides of the movable sleeve 12 and the fixed pipe 11, respectively. The docking plate 14 is located at the outer end of the movable sleeve 12, and the locking plate 15 slides within the docking plate 14. The fixed pipe 11 is connected to the drain pipe 24 of the sewage treatment equipment via a pipe. The movable sleeve 12 pulls and extends the telescopic structure 13, aligning the docking plate 14 with the access end of the adjacent sewage treatment equipment. Connecting flanges are provided on the docking plate 14 and the fixed pipe 11, and they are fixedly connected by reinforcing bolts.

[0034] The telescopic structure 13 includes a rubber ring 131, an inner tube 132, an outer tube 133, a rubber strip 134, and an arc plate 135. The rubber strip 134 is evenly distributed inside the inner tube 132. Three annular structures are provided between the inner side of the outer tube 133 and the outer side of the inner tube 132. The annular structures are composed of the rubber ring 131 and the arc plate 135, and the arc plate 135 is arranged on both the inner and outer sides of the rubber ring 131. The inner side of the outer tube 133 is inclined. The inner tube 132 expands elastically outward through the rubber strip 134, and the arc plate 135 slides and compresses on the inner side of the outer tube 133 and the outer side of the inner tube 132. When the inner tube 132 moves, it squeezes the arc plate 135 so that it slides on the inclined surface of the outer tube 133, and the seal is achieved through elastic deformation.

[0035] Based on the connection between adjacent wastewater treatment devices via connecting component 1, an installation method for wastewater treatment equipment is provided, with the specific installation steps as follows:

[0036] S1: Connect the fixed pipe 11 to the side outlet end of the equipment body 2 through a flange, and manually pull the movable sleeve 12 to put the elastic support structure of the telescopic structure 13 into a stretched state.

[0037] S2: When the telescopic structure 13 is stretched, the inner tube 132 squeezes the arc plate 135 and causes the arc plate 135 to slide in an inclined position inside the outer tube 133, thereby the arc plate 135 compresses the rubber ring 131 and seals the space between the outer tube 133 and the inner tube 132 under the elastic expansion of the inner tube 132.

[0038] S3: After the telescopic structure 13 is stretched, rotate the movable sleeve 12 and the telescopic structure 13 around the fixed pipe 11, and adjust the stretching length of the telescopic structure 13 so that the movable sleeve 12 is aligned with the inlet end of the adjacent sewage treatment equipment.

[0039] S4: Thus, the docking plate 14 corresponds to the periphery of the inlet end of the adjacent sewage treatment equipment, and the locking plate 15 slides into the docking plate 14 on the outside of the inlet end to make a staggered connection between the inlet ends of the adjacent sewage treatment equipment.

[0040] In this invention, when connecting and installing wastewater treatment equipment, the connection ends of two wastewater treatment devices are connected by a fixed pipe 11 and a movable sleeve 12. When there is a misalignment between the wastewater treatment devices, the movable sleeve 12 is manually pulled to stretch the telescopic structure 13 connecting the fixed pipe 11 and the movable sleeve 12. When there is a height difference at the inlet end, the movable sleeve 12 rotates around the fixed pipe 11, thereby allowing the connecting plate 14 at the outer end of the movable sleeve 12 to move to the side of the inlet end of the wastewater treatment device. The inlet end of the wastewater treatment device is then closed by the locking plate 15. This allows the connection between adjacent wastewater treatment devices to be installed even when they are misaligned, avoiding the difficulty of installation when the devices are misaligned.

[0041] A sewage treatment device is applied to the above-mentioned installation method of a sewage treatment device. The sewage treatment device includes a connecting component 1, a device body 2, a blower 3, a stair frame 4, a base 5, and a pump station 6. The blower 3 and the stair frame 4 are respectively arranged on the left and right sides of the device body 2. The connecting component 1 is arranged at the outlet end on the side of the device body 2. The device body 2 is fixed to the surface of the base 5. The pump station 6 is installed on the upper surface of the device body 2.

[0042] The main body 2 of the equipment is provided with a cleaning mechanism 21, a treatment pool 22, a housing 23, a drain pipe 24, and a water inlet pipe 25. There are four treatment pools 22, which are symmetrically distributed inside the housing 23. The water inlet pipe 25 and the drain pipe 24 are respectively located on the left and right sides of the housing 23, and are located at the left inlet end and the right outlet end of the treatment pool 22, respectively. The cleaning mechanism 21 is located on the upper end of the housing 23 and is correspondingly distributed on the upper end of the treatment pool 22. The cleaning mechanism 21 is connected to an external power line and a water pipe connector. Power is transmitted through the power line to drive the cleaning mechanism 21 to extend and retract, so that the lower end of the cleaning mechanism 21 moves downward along the inner wall of the treatment pool 22 and rotates, so that the lower end of the cleaning mechanism 21 is flushed along the bottom of the treatment pool 22.

[0043] Furthermore, the two treatment tanks 22 on the left are connected to the inlet pipe 25 at a higher position, while the treatment tank 22 on the right is connected to the drain pipe 24 at a lower position. The blower 3 can deliver oxygen to the space above the four treatment tanks 22. The two pipes of the pump station 6 that draw sewage are equipped with filter screens to prevent the bottom sediment from being drawn out. After the sewage in the two treatment tanks on the left undergoes an oxidation reaction, impurities and microorganisms settle out, and the oxidized sewage is then drawn out by the pump station 6 to the two treatment tanks on the right.

[0044] Furthermore, the four treatment tanks 22 are equipped with four sealing plates on their sides for discharging sediment. By manually opening the sealing plates, the sediment in the four treatment tanks 22 can be cleaned. The water pipe connectors connected to the cleaning mechanism 21 can connect to multiple water pipes, and the water pressure of the multiple water pipes can be kept consistent through the water pipe connectors. The opening and closing of the multiple water pipes can also be controlled uniformly.

[0045] The cleaning mechanism 21 includes a motor 211, a processor 212, a first telescopic rod 213, a first hydraulic actuator 214, a second hydraulic actuator 215, and a rinsing mechanism 216. The output end of the motor 211 is equipped with the first hydraulic actuator 214, which drives the first hydraulic actuator 214 to rotate. The processor 212 is located outside the first hydraulic actuator 214 and is electrically connected to the rinsing mechanism 216, the second hydraulic actuator 215, and the first hydraulic actuator 214. The processor 212 drives the first telescopic rod 213 at the output end of the first hydraulic actuator 214 to extend and retract downwards, and causes the second hydraulic actuator 215 at the lower end of the first telescopic rod 213 to drive the rinsing mechanism 216 to rotate. The rinsing mechanism 216 extends and retracts outwards and moves up and down against the inner wall of the treatment tank 22.

[0046] The rinsing mechanism 216 includes a track bar 31, a rotating plate 32, a scraper structure 33, a second telescopic rod 34, and a third hydraulic actuator 35. The second telescopic rod 34 is located at the output end of the third hydraulic actuator 35, which is located at the outer end of the rotating plate 32. The rotating plate 32 is equipped with a screw. The output end of the second hydraulic actuator 215 drives the screw inside the rotating plate 32 to move, causing the rotating plate 32 to rotate at the lower end of the second hydraulic actuator 215. The processor 212 uses an electrical signal to drive the second telescopic rod 34 at the output end of the third hydraulic actuator 35 to extend and retract, causing the scraper structure 33 to extend outward in a straight line along the track bar 31.

[0047] Furthermore, the screw is equipped with locking blocks at both ends. The locking blocks are fixed to the lower end of the second hydraulic unit 215, and the output end of the second hydraulic unit 215 is threadedly engaged with the screw, causing the screw to rotate under the constraint and support of the locking blocks, and driving the rotating plate 32 to rotate.

[0048] Furthermore, the processor 212 is connected to an external wire, and the processor 212 is electrically connected to the motor 211, the first hydraulic unit 214, the second hydraulic unit 215, and the flushing mechanism 216. Under the control of the running program, the processor 212 electrically controls the motor 211, the first hydraulic unit 214, the second hydraulic unit 215, and the flushing mechanism 216 respectively. It should be noted that the processor 212 can only rotate 90° with the first hydraulic unit 214, and the length of the wire connected to the processor 212 does not affect the connection of the wire within the 90° rotation range.

[0049] Furthermore, when the rinsing mechanisms 216 on the left and right sides move up and down, they can only rinse the inner walls of the treatment pools 22 on both sides. The first hydraulic actuator 214 at the output end of the motor 211 is driven by the external power wire of the motor 211 to drive the processor 212 to rotate. At this time, the first telescopic rod 213 rotates in tandem with the first hydraulic actuator 214, thereby driving the rinsing mechanism 216 to rotate and rinse the inner walls of the treatment pools 22 on the other two sides.

[0050] Furthermore, the second telescopic rod 34 has an inclination angle of 30°, which corresponds to the corner of the inner wall of the treatment pool 22, allowing the end of the scraper structure 33 to move relative to the inner wall of the treatment pool 22.

[0051] It is necessary to explain that the four treatment pools 22 are square in shape when viewed from above. When the cleaning mechanism 21 scrapes and rinses the inner wall of the treatment pool 22 from both sides, the length of the rinsing mechanism 216 extending outward and touching the inner wall of the treatment pool 22 is consistent in both cases, so as to avoid different extension lengths of the scraper structure 33.

[0052] In this invention, when the cleaning mechanism 21 rinses the inner wall of the treatment tank 22, the processor 212 first controls the rinsing mechanism 216 to hydraulically extend and retract outward, so that the outer end of the rinsing mechanism 216 abuts against the inner wall of the treatment tank 22. This causes the processor 212 to drive the first telescopic rod 213 at the output end of the first hydraulic actuator 214 to extend and retract downward. Subsequently, the second hydraulic actuator 215 and the rinsing mechanism 216 move downward. Simultaneously, the external water pipe connected to the scraper structure 33 on the rinsing mechanism 216 opens and closes, causing the outer end of the rinsing mechanism 216 to abut against the inner wall of the treatment tank 22, resulting in rinsing and scraping. After scraping, the rinsing mechanism 216 retracts and retracts upward via the first telescopic rod 213. After the motor 211 drives the first hydraulic actuator 214 to rotate 90°, the outward extension and retraction of the rinsing mechanism 216 is repeated. The flushing mechanism 216 moves downward again to flush and scrape the four sides of the inner wall of the treatment tank 22. After the four sides are scraped, the processor 212 controls the output end of the second hydraulic device 215 to move and cooperate with the screw on the rotating plate 32. At this time, the two rotating plates 32 on the left and right sides rotate and swing downward with the lower end of the second hydraulic device 215 as the center. While the rotating plates 32 are rotating, the processor 212 controls the first hydraulic device 214 to extend and retract the first telescopic rod 213 at the output end. At this time, the length of the scraper structure 33 is kept the same as the inner wall of the treatment tank 22. At this time, the outer end of the scraper structure 33 can also abut against the bottom corner of the treatment tank 22, so that the scraper structure 33 maintains a certain abutment force against the bottom of the treatment tank 22 under the rotation of the rotating plate 32 to scrape and flush.

[0053] In this invention, when the outer end of the rinsing mechanism 216 extends and retracts, the two third hydraulic actuators 35 on the rinsing mechanism 216 are simultaneously controlled by the processor 212, causing the second telescopic rod 34 at the output end of the third hydraulic actuator 35 to extend outward toward the scraper structure 33 and abut against the inner wall of the treatment pool 22. At this time, the scraper structure 33 extends linearly along the track of the track bar 31, and the width of the scraper structure 33 is the same as one side of the treatment pool 22. Moreover, the left and right ends of the scraper structure 33 are "L" shaped, which can abut against the right-angled edge of the inner wall of the treatment pool 22. Since the first hydraulic actuator 214 needs to rotate, the inner walls of the four sides of the treatment pool 22 are scraped and rinsed twice. Thus, the "L" shape at both ends of the scraper structure 33 allows the corners of the inner wall of the treatment pool 22 to be scraped once more under the rotation scraping of the cleaning mechanism 21, avoiding the problem that the corners of the treatment pool 22 are not easy to clean.

[0054] The scraper structure 33 includes a water supply pipe 331, a water guide plate 332, a drain connector 333, a flushing head 334, a friction strip 335, and a main body 336. The water supply pipe 331 is located at the upper end of the drain connector 333 and is connected to a water pipe connector. The drain connectors 333 are arranged linearly inside the main body 336, and the main body 336 extends linearly via a track bar 31. The water guide plate 332 is located on the side of the drain connector 333, and the flushing head 334 is inclined. The friction strip 335 is set at an angle of 30° to the outer end of the water intake plate 332 and is set at the outer end of the main body 336. The friction strip 335 abuts against the inner wall of the treatment tank 22. The friction strip 335 scrapes against the inner wall of the treatment tank 22 by the contraction of the first telescopic rod 213. When the rotating plate 32 rotates, the friction strip 335 abuts against the bottom of the treatment tank 22, and the first telescopic rod 213 retracts upward when the rotating plate 32 rotates, so that the flushing head 334 and the friction strip 335 scrape against the bottom of the inner wall of the treatment tank 22 in a concave shape.

[0055] A spring rod 301 and a sleeve 302 are provided between adjacent drain joints 333. The sleeve 302 has inner and outer tubes that slide relative to each other. The spring rod 301 is located at the top of the inner tube of the sleeve 302 and is connected to the side of the adjacent drain joint 333. When the drain joint 333 extends with the main body 336, the inner and outer tubes of the sleeve 302 slide relative to each other and elastically press against the adjacent drain joint 333 through the spring rod 301.

[0056] The rinsing head 334 is provided with a spray plate 41 and an opening groove 42. The opening groove 42 is located inside the spray plate 41, and both the upper and lower sides of the opening groove 42 are open. There is a height difference between adjacent spray plates 41.

[0057] Furthermore, the main body 336 is divided into upper and lower layers corresponding to the positions of the drain connector 333 and the water inlet plate 332. The lower end of the drain connector 333 is provided with a ball bearing rod, which slides in the corresponding ball bearing groove inside the lower end of the main body 336. The upper end of the drain connector 333 is connected to the water supply pipe 331, which is provided with a plate-like structure. The plate-like structure can slide on the upper surface of the main body 336. When the scraper structure 33 extends linearly through the track bar 31, the upper and lower layers of the main body 336 move on the upper and lower sides of the water inlet plate 332, so that the upper and lower layers of the main body 336 are supported by the corresponding plate-like structure and ball bearing rod. This supports the drain connector 333 when it is stretched, ensuring that the drain connectors 333 are evenly distributed under the elastic force of the spring rod 301, and preventing the drain connectors 333 from tilting easily when they are stretched together without support.

[0058] Furthermore, the height difference between adjacent spray plates 41 ensures that the water streams sprayed from the internal opening slots 42 of the spray plates 41 do not interfere with each other.

[0059] Furthermore, there are two friction strips 335, distributed on the outer ends of the upper and lower layers of the main body 336. The friction strips 335 are made of sponge material. After the friction strips 335 abut against the inner wall of the treatment tank 22, the sponge material is compressed.

[0060] In this invention, water flows through the pipe joint connected to the water supply pipe 331, and flows into the drain joint 333 and towards the flushing head 334 at the outer end of the water guide plate 332. Under the push of the second telescopic rod 34 on the scraper structure 33, the main body 336 extends linearly along the track bar 31. At this time, the spacing between the drain joints 333 changes under the elasticity of the spring rod 301, and they extend in an equidistant arrangement. This causes the friction strip 335 at the outer end of the main body 336 to abut against the inner wall of the treatment tank 22. Under the lifting and lowering movement of the scraper structure 33, the compressed friction strip 335 scrapes the inner wall of the treatment tank 22, removing the scraped material. The flushing head 334 in the middle of the tube generates an inclined water flow to flush the inner wall of the treatment tank 22. After flushing, the friction strip 335 above can scrape and rub the inner wall of the treatment tank 22 again. When the scraper structure 33 rotates to the bottom of the treatment tank 22, the compression of the friction strip 335 can deform and scrape the corner. The outer end of the flushing mechanism 216 performs concave motion to flush and scrape the inner wall of the treatment tank 22 to the bottom. By performing concave motion scraping on the four sides and bottom of the inner wall of the treatment tank 22 through the flushing mechanism 216, it has the effect of scraping the corner of the inner wall of the treatment tank 22, avoiding the corner of the treatment tank 22 from being difficult to clean.

[0061] The above description is merely a preferred embodiment of the present invention, and therefore should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of the patent and the contents of the specification should still fall within the scope of the present invention.

Claims

1. A method for installing wastewater treatment equipment, wherein adjacent wastewater treatment equipment are connected by a connecting component, characterized in that... The connecting assembly includes a fixed pipe, a movable sleeve, a telescopic structure, a docking plate, and a locking plate. The telescopic structure is connected to the sides of the movable sleeve and the fixed pipe on its left and right sides, respectively. The docking plate is located at the outer end of the movable sleeve, and the locking plate slides inside the docking plate. The fixed pipe is connected to the drain pipe of the sewage treatment equipment through a pipe. The movable sleeve pulls the telescopic structure to extend it, and the docking plate aligns with the access end of the adjacent sewage treatment equipment. The docking plate and the fixed pipe are respectively provided with connecting flanges and are fixedly connected by reinforcing bolts. The telescopic structure comprises a rubber ring, an inner tube, an outer tube, rubber strips, and an arc-shaped plate. The rubber strips are evenly distributed inside the inner tube. Three annular structures are provided between the inner side of the outer tube and the outer side of the inner tube. The annular structures are composed of rubber rings and arc-shaped plates, with the arc-shaped plates positioned on both the inner and outer sides of the rubber rings. The inner side of the outer tube is inclined. The inner tube expands elastically outward through the rubber strips, and the arc-shaped plates slide and compress on the inner and outer sides of the outer tube. When the inner tube moves, it squeezes the arc-shaped plates, causing them to slide on the inclined surface of the outer tube, thus achieving a seal through elastic deformation. Based on the connection between adjacent wastewater treatment devices via connecting components, a wastewater treatment device installation method is described, with the following specific installation steps: S1: Connect the fixed pipe to the side outlet end of the equipment body through a flange, and manually pull the movable sleeve to put the elastic support structure of the telescopic structure in a stretched state. S2: When the telescopic structure is stretched, the inner tube squeezes the arc plate and makes the arc plate slide in an inclined position inside the outer tube, thereby the arc plate compresses the rubber ring and seals the gap between the outer tube and the inner tube under the elastic expansion of the inner tube. S3: After the telescopic structure is stretched, rotate the movable sleeve and the telescopic structure with the fixed pipe as the center, and adjust the stretching length of the telescopic structure so that the movable sleeve is aligned with the inlet end of the adjacent sewage treatment equipment. S4: Thus, the docking plate corresponds to the outer periphery of the inlet end of the adjacent sewage treatment equipment, and the locking plate slides into the docking plate on the outside of the inlet end to make a staggered connection between the inlet ends of the adjacent sewage treatment equipment.
