Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a wastewater treatment device for municipal engineering. Background Technology

[0002] Municipal engineering wastewater treatment plants are comprehensive facilities integrating primary, secondary, and tertiary treatment processes. They are mainly used to treat urban domestic sewage and some industrial wastewater. They typically include coarse and fine screens, grit chambers, biological treatment systems, and technologies such as reverse osmosis or ultraviolet disinfection to further remove harmful substances and pathogenic microorganisms from the water.

[0003] Patent publication number CN221894730U relates to a sewage treatment device for municipal engineering, including a base plate. Support plates are fixedly installed at both ends of the top of the base plate, and a bearing block is fixedly installed on the top of each support plate. A first semi-annular groove for carrying sewage is formed on the left side of the support plate, and a second semi-annular groove for carrying impurities is formed on the right side of the support plate. The device is used to transfer sewage impurities from the first semi-annular groove to a treatment component in the second semi-annular groove, and the treatment component is located on the base plate. This patent, by setting up the treatment component, enables the transfer of sewage impurities from the first semi-annular groove to the second semi-annular groove, thereby solving the problem that current treatment devices are unable to treat sediments. This allows for the effective removal of sewage impurities to a certain extent, improving the treatment efficiency of sewage for municipal engineering.

A conveyor belt is arranged between the rotating wheels, and a scraper is inclinedly arranged on the surface of the conveyor belt. A foam collection frame is fixedly mounted on the surface of the outer casing, a composite filter plate is fixedly mounted on the lower surface of the outer casing, and a debris collection frame is fixedly mounted on the side surface of the outer casing. Filter holes are fixedly mounted on the lower surface of the debris collection frame, which can separate debris inside the debris collection frame from sewage. The sewage flows into the water storage frame for further processing through the filter holes.

[0007] Preferably, the interior of the outer shell is provided with an arc surface, and the output end of the motor rotates through the outer shell. During the transmission process, the scraper moves to the upper surface of the sewage and scrapes the foam on the upper surface of the sewage into the foam collection frame. One end of the foam collection frame is lower and is set as an inclined surface, which can help the foam to flow out.

[0008] Preferably, the surface of the foam collection frame is provided with a filter plate, and the debris collection frame is provided with an inclined surface. The composite filter plate can block debris and large particles such as mud on the upper surface of the composite filter plate. When the scraper is driven to the upper surface of the composite filter plate, it can collect the debris on the surface and drive it into the interior of the debris collection frame.

[0009] Preferably, the spraying device includes a reciprocating screw, a connecting plate 1 is slidably mounted on the outer surface of the reciprocating screw, a connecting plate 2 is fixedly mounted on the surface of the connecting plate 1, a slot is formed on the surface of the water storage frame, a medicine storage frame is slidably mounted on the inner surface of the slot, a spraying frame is fixedly mounted on the surface of the medicine storage frame, and a water outlet is formed on the surface of the medicine storage frame. The rotation of the reciprocating screw drives the connecting plate 1 to reciprocate, and the reciprocating motion of the connecting plate 1 drives the connecting plate 2 to reciprocate.

[0010] Preferably, a second conveyor belt is provided between the rotating shaft and the reciprocating screw, and the reciprocating screw is rotatably installed on the inner surface of the water storage frame. The rotation of the motor drives the second conveyor belt to drive the reciprocating screw to rotate.

[0014] This invention provides a sewage treatment device for municipal engineering. It has the following beneficial effects: (1) The separation device utilizes a motor, rotating shaft, rotating wheel and conveyor belt to effectively improve the efficiency and quality of sewage treatment. Foam and bottom debris usually contain a large amount of organic matter, grease and suspended solids. If they are not removed in time, they may affect the subsequent treatment process and increase the difficulty of treatment. The separation device can also reduce the accumulation of pollutants on the surface of sewage tanks, prevent secondary pollution of water quality, ensure the cleanliness of water bodies, improve the stability and treatment capacity of water treatment systems, thereby achieving more efficient sewage treatment and meeting stricter discharge standards.

[0015] (2) The spraying device can effectively ensure that the agent is evenly distributed in the sewage, thereby improving the treatment effect of the agent. The agent is automatically dispensed by the rotation of the motor, avoiding the impact of excessive or insufficient agent on water purification. Through this control, the degradation efficiency of harmful substances in sewage is improved, unnecessary waste is reduced, and operating costs are effectively reduced. Even spraying can also improve the stability and treatment capacity of sewage treatment facilities, ensuring that the treatment process is more efficient and controllable, and meeting increasingly stringent discharge requirements.

[0016] (3) The debris treatment device can effectively collect the debris. After the debris enters the debris collection box, the filter holes at the bottom of the debris collection box can allow the sewage in the debris to penetrate into the water storage box at the bottom, which enhances the sewage treatment effect of the equipment. When the debris collection box is about to be full, the baffle can be pressed to block the sewage and debris inside the shell, making it convenient to clean the inside of the debris collection box. After closing the baffle, wait for a period of time to filter the sewage in the debris. When the rotating door is opened, there is no sewage in the debris, which makes it easier to clean it and reduces the treatment cost. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-7 One embodiment of the present invention is: a sewage treatment device for municipal engineering, including a shell 1, a water storage frame 2 fixedly installed on the lower surface of the shell 1, and also including a separation device, a chemical spraying device and a debris collection device; The separation device includes a motor 301, which is fixedly installed on the surface of the outer casing 1.

A filter hole 309 is fixedly installed on the lower surface of the debris collection frame 308. The filter hole 309 on the lower surface of the debris collection frame 308 can separate the debris inside the debris collection frame 308 from the sewage. The sewage flows into the water storage frame 2 for further processing through the filter hole 309.

[0021] The interior of the outer casing 1 is provided with an arc surface. The output end of the motor 301 rotates through the outer casing 1. During the transmission process, the scraper 305 moves to the upper surface of the sewage and scrapes the foam on the upper surface of the sewage into the foam collection frame 306. One end of the foam collection frame 306 is lower and is set as a slope, which can help the foam to flow out.

[0022] The surface of the foam collection frame 306 is provided with a filter plate, and the debris collection frame 308 is provided with an inclined surface. The composite filter plate 307 can block debris and large particles such as mud on the upper surface of the composite filter plate 307. When the scraper 305 is driven to the upper surface of the composite filter plate 307, it can collect the debris on the surface and drive it into the interior of the debris collection frame 308.

[0023] In this embodiment, during operation: The motor 301 is started, which rotates the shaft 302. The shaft 302 rotates, which in turn rotates the wheel 303. The wheel 303 is rectangular in shape. The rotation of the wheel 303 drives the conveyor belt 304, which in turn drives the scraper 305. The scraper 305 is fixedly installed at a certain angle on the surface of the conveyor belt 304. During transmission, the scraper 305 moves to the surface of the wastewater and scrapes the foam from the surface into the foam collection frame 306. One end of the foam collection frame 306 is lower and sloped to help the foam flow out. A filter plate is provided on the surface of the foam collection frame 306. The filter plate helps the collected wastewater to be discharged back into the outer shell 1. A composite filter plate 307 is provided on the lower surface of the outer shell 1. The composite filter plate 307 can block large particles such as debris and mud on its upper surface. When the scraper 305 is driven to the upper surface of the composite filter plate 307, it can collect the surface debris and transport it into the debris collection frame 308. The lower surface of the debris collection frame 308 is provided with filter holes 309, which can separate the debris inside the debris collection frame 308 from the sewage. The sewage flows into the water storage frame 2 through the filter holes 309 for further processing. This separation device, using a motor 301, a rotating shaft 302, a rotating wheel 303 and a conveyor belt 304, can effectively improve the efficiency and quality of sewage treatment. Foam and bottom debris usually contain a large amount of organic matter, grease and suspended solids. If they are not removed in time, they may affect the subsequent treatment process and increase the difficulty of treatment. This separation device can also reduce the accumulation of pollutants on the surface of the sewage tank, prevent secondary pollution of water quality, ensure the cleanliness of the water body, improve the stability and treatment capacity of the water treatment system, thereby achieving more efficient sewage treatment and meeting stricter discharge standards.

[0024] Please see Figures 1-7 Based on the above embodiments, in another embodiment of the present invention, the spraying device includes a reciprocating screw 401, a connecting plate 403 slidably mounted on the outer surface of the reciprocating screw 401, a connecting plate 404 fixedly mounted on the surface of the connecting plate 403, a slot is formed on the surface of the water storage frame 2, a medicine storage frame 405 is slidably mounted on the inner surface of the slot, a spraying frame 406 is fixedly mounted on the surface of the medicine storage frame 405, and a water outlet 408 is formed on the surface of the water storage frame 2. The rotation of the reciprocating screw 401 drives the connecting plate 403 to reciprocate, and the reciprocating motion of the connecting plate 403 drives the connecting plate 404 to reciprocate.

[0025] A second conveyor belt 402 is provided between the rotating shaft 302 and the reciprocating screw 401. The reciprocating screw 401 is rotatably installed on the inner surface of the water storage frame 2. The rotation of the motor 301 drives the second conveyor belt 402 to drive the reciprocating screw 401 to rotate.

[0026] The connecting plate 403 has a threaded hole inside, and the reciprocating screw 401 is connected to the threaded hole by thread. The surface of the spraying frame 406 has a storage tank 407. During the reciprocating motion, the connecting plate 404 is misaligned with the storage tank 407, causing the agent to fall into the filtered wastewater, purifying the wastewater. After reaching the discharge standard, the wastewater is discharged from the outlet 408.

[0027] In this embodiment, during operation: a reciprocating screw 401 is rotatably mounted on the inner surface of the water storage frame 2. The motor 301 rotates, driving the second conveyor belt 402, which in turn drives the reciprocating screw 401 to rotate. A connecting plate 403 is slidably mounted on the outer surface of the reciprocating screw 401. A threaded groove is formed inside the connecting plate 403, and the reciprocating screw 401 is threaded into the groove. The rotation of the reciprocating screw 401 drives the first connecting plate 403 to reciprocate, which in turn drives the second connecting plate 404 to reciprocate. The surface of the water storage frame 2 has slots, and a medicine storage frame 405 is slidably mounted on the inner surface of these slots. A spraying frame 406 is fixedly mounted on the surface of the medicine storage frame 405. The surface of the device has a storage tank 407. During the reciprocating motion of the connecting plate 404, it is misaligned with the storage tank 407, causing the chemical to fall into the filtered wastewater, purifying the wastewater. After the water quality meets the discharge standards, it is discharged from the outlet 408. This chemical dispensing device can effectively ensure that the chemical is evenly distributed in the wastewater, thereby improving the treatment effect. The chemical is automatically dispensed by the rotation of the motor 301, avoiding the impact of excessive or insufficient chemical on water purification. Through this control, the degradation efficiency of harmful substances in wastewater is improved, unnecessary waste is reduced, and operating costs are effectively reduced. Even chemical dispensing can also improve the stability and treatment capacity of the wastewater treatment facility, ensuring that the treatment process is more efficient and controllable, and meeting increasingly stringent discharge requirements.

[0028] Please see Figures 1-7 Based on the above embodiments, in another embodiment of the present invention, the debris collection device includes a baffle 501, which is slidably installed on the surface of the outer shell 1. A sliding groove 503 is provided on the surface of the outer shell 1. A sliding block 504 is slidably installed on the inner surface of the sliding groove 503. A connecting plate 506 is rotatably installed on the surface of the sliding block 504. A connecting plate 507 is rotatably installed at the end of the connecting plate 506 away from the sliding block 504. A sliding block 508 is fixedly installed at the end of the connecting plate 507 away from the connecting plate 506. A rotating door 509 is rotatably installed on the side of the debris collection frame 308 away from the outer shell 1. After the sewage inside the debris collection frame 308 flows into the water storage frame 2 through the filter hole 309, the rotating door 509 is opened to clean the inside of the debris collection frame 308. After cleaning, the rotating door 509 is closed.

[0029] A spring 502 is provided between the baffle 501 and the debris collection box 308, and a spring 505 is provided between the sliding block 504 and the sliding groove 503. When the spring 502 resets, it causes the baffle 501 to move upward. At this time, the debris can flow into the debris collection box 308 again. When the baffle 501 is pressed down again, the spring 505 resets and limits the position again.

[0030] In this embodiment, during operation: After the motor 301 has been running for a period of time, the scraper 305 continuously scrapes debris into the debris collection box 308. Once the debris collection box 308 is full, the baffle 501 is pressed down, the spring 502 contracts, and the baffle 501 moves downward. When it moves below the sliding block 504, the sliding block 504 pops out, restricting the baffle 501 from moving upward. The baffle 501 blocks sewage and debris from entering the debris collection box 308. The sewage inside the debris collection box 308 flows into the water storage box 2 through the filter hole 309 and then the rotating door 509 is opened to clean the inside of the debris collection box 308. After cleaning, the rotating door 509 is closed, and the sliding block 508 protruding from the upper surface of the outer shell 1 is pressed. The sliding block 508 moves downward, causing one end of the connecting plate 507 to move downward. The other end of the connecting plate 507 is squeezed and moves to the right, causing the connecting plate 506 to move to the right. The rightward movement causes the sliding block 504 to move to the right, the spring 505 to contract, and the spring 502 to reset, causing the baffle 501 to move upward. At this time, the debris can flow back into the debris collection box 308. When the baffle 501 is pressed down again, the spring 505 resets and limits its position again. This debris handling device can effectively collect the debris. After the debris enters the debris collection box 308, the filter hole 309 at the bottom of the debris collection box 308 can allow the sewage in the debris to penetrate into the bottom water storage box 2, enhancing the equipment's sewage treatment effect. When the debris collection box 308 is about to be full, pressing the baffle 501 can block the sewage and debris inside the outer shell 1, making it easier to clean the inside of the debris collection box 308. After closing the baffle 501, waiting for a period of time can filter out the sewage in the debris. Opening the rotating door 509 again will remove the sewage from the debris, making it easier to clean and reducing processing costs.

[0031] 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 variations 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.
