Description

Technical Field

[0001] This application relates to the technical field of sedimentation tank cleaning, and more particularly to a sludge scraping device at the bottom of a sewage sedimentation tank. Background Technology

[0002] Wastewater sedimentation tanks are mainly used for purifying and settling wastewater. After a long period of use, sludge will accumulate at the bottom of the sedimentation tank. Therefore, it is necessary to clean the sludge at the bottom of the sedimentation tank regularly. The sludge at the bottom of the sedimentation tank often has a certain adhesion to the bottom of the sedimentation tank. Therefore, when cleaning the sludge settled at the bottom of the sedimentation tank, it is necessary to scrape it off first before it can be cleaned.

[0003] However, the length of the current sludge scraping device at the bottom of the sewage sedimentation tank cannot be automatically adjusted. Therefore, it is impossible to automatically adjust the length of the device and install it on the inlet of the sewage sedimentation tank for different sizes of sewage sedimentation tanks. This often requires a lot of manual intervention, and the adjustment and installation time is long and inefficient, resulting in low efficiency of sludge scraping at the bottom of the sewage sedimentation tank. Utility Model Content

[0004] This application provides a sludge scraping device for the bottom of a sewage sedimentation tank, which solves the technical problem that the length of existing sludge scraping devices for the bottom of sewage sedimentation tanks cannot be automatically adjusted. Therefore, it is impossible to automatically adjust the length of the scraping device for sewage sedimentation tanks of different sizes. The device is installed on the inlet of the sewage sedimentation tank and often requires a lot of manual intervention. The adjustment and installation time is long and the efficiency is low, resulting in low efficiency of sludge scraping at the bottom of the sewage sedimentation tank.

[0005] In view of this, this application provides a sludge scraping device for the bottom of a sewage sedimentation tank, including a rectangular crossbar, a controller, and a sludge scraping mechanism. The controller is located on the upper end face of the rectangular crossbar, and the sludge scraping mechanism is located below the rectangular crossbar. Multi-stage electric telescopic rods are respectively provided at the left and right ends of the rectangular crossbar. The multi-stage electric telescopic rods are electrically connected to the controller. A motor cavity is provided inside the rectangular crossbar, and a power motor is invertedly provided inside the motor cavity. The rear end of the power motor is fixedly connected to the top of the motor cavity. The power motor is electrically connected to the controller. A transmission shaft is fixedly provided on the output shaft of the power motor. The transmission shaft passes through the bottom of the rectangular crossbar and is detachably connected to the sludge scraping mechanism.

[0006] Optionally, the sludge scraping mechanism includes a rotating cylinder and sludge scraping plates. Sludge scraping plates are respectively provided on both sides of the rotating cylinder. The sludge scraping plates are detachably connected to the rotating cylinder. A connecting rod is provided at the upper end of the rotating cylinder. The lower end of the connecting rod is detachably connected to the upper end of the rotating cylinder. The upper end of the connecting rod is detachably connected to the lower end of the drive shaft.

[0007] Optionally, the lower end of the scraper blade is provided with a long scraping rubber strip, the upper end of which is detachably connected to the lower end of the scraper blade, and the lower end of the rotating cylinder is provided with a short scraping rubber strip, the lower end of which is detachably connected to the upper end of which is the short scraping rubber strip.

[0008] Optionally, the telescopic end of the multi-stage electric telescopic pole is provided with a placement component, which is fixedly connected to the multi-stage electric telescopic pole. The placement component consists of a horizontal block and a vertical block, and one end of the horizontal block near the telescopic end of the multi-stage electric telescopic pole is fixedly connected to the upper end of the vertical block.

[0009] Optionally, the lower end of the horizontal block and the side of the vertical block away from the multi-stage electric telescopic rod are both provided with anti-slip rubber surfaces.

[0010] Optionally, the rectangular crossbar has a pump chamber, and an electric water pump is installed in the pump chamber. The electric water pump is fixedly connected to the bottom of the pump chamber. Two water outlet vertical pipes are provided below the rectangular crossbar. A water supply pipe is provided in the rectangular crossbar. One end of the water supply pipe passes through the upper end of the water outlet vertical pipe and communicates with the water outlet vertical pipe. The water outlet end of the electric water pump passes through the pump chamber and communicates with the other end of the water supply pipe. The water inlet end of the electric water pump passes through the pump chamber and communicates with an external water source pipe.

[0011] Optionally, the lower end of the motor cavity is provided with a through hole, a bearing is provided in the through hole, the transmission shaft passes through the bearing and is fixedly connected to the output shaft of the power motor, and a limiting turntable is sleeved on the part of the transmission shaft that passes through the bearing and is placed in the motor cavity.

[0012] As can be seen from the above technical solutions, the embodiments of this application have the following advantages:

[0013] This application provides a bottom sludge scraping device for sewage sedimentation tanks. A controller allows the electric multi-stage telescopic rods at both ends of a rectangular crossbar to automatically extend or retract. This enables the device to be installed on sewage sedimentation tanks of varying diameters by automatically adjusting the extension and retraction length of the electric multi-stage telescopic rods to a suitable installation position. When scraping begins, a power motor drives a transmission shaft, which in turn drives the scraping mechanism. This rotation removes the sludge from the bottom of the sedimentation tank. Thus, the length of the bottom sludge scraping device can be automatically adjusted for different diameters of sewage sedimentation tanks, eliminating the need for excessive manual adjustment, saving labor, and reducing installation and adjustment time. This high efficiency improves the efficiency of sludge removal from the bottom of sewage sedimentation tanks.

[0014] This application also improves the efficiency of sludge removal at the bottom of the sewage sedimentation tank by setting up a water pump, a water supply pipe, and an outlet vertical pipe. The water pump delivers clean water to the water supply pipe, which then delivers it to the outlet vertical pipe. The outlet vertical pipe sprays the clean water into the bottom of the sewage sedimentation tank. This allows the sludge scraping mechanism to soften the relatively dry and hard sludge that is tightly attached to the bottom of the sedimentation tank during the sludge scraping process, thereby improving the sludge scraping efficiency at the bottom of the sewage sedimentation tank.

[0022] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0023] For easier understanding, please refer to Figures 1 to 2This application provides an embodiment of a sludge scraping device for the bottom of a sewage sedimentation tank, comprising a rectangular crossbar 1, a controller 4, and a sludge scraping mechanism 2. The controller 4 is located on the upper end face of the rectangular crossbar 1, and the sludge scraping mechanism 2 is located below the rectangular crossbar 1. Multi-stage electric telescopic rods 3 are respectively provided at the left and right ends of the rectangular crossbar 1. The multi-stage electric telescopic rods 3 are electrically connected to the controller 4. A motor cavity 5 is provided inside the rectangular crossbar 1, and a power motor 6 is invertedly installed inside the motor cavity 5. The rear end of the power motor 6 is fixedly connected to the top of the motor cavity 5. The power motor 6 is electrically connected to the controller 4. A transmission shaft 7 is fixedly installed on the output shaft of the power motor 6. The transmission shaft 7 extends through the bottom of the rectangular crossbar 1 and is detachably connected to the sludge scraping mechanism 2. With the above configuration, when the sludge scraping device for the bottom of the sewage sedimentation tank needs to scrape sludge from the bottom of the sewage sedimentation tank, the controller 4, multi-stage electric telescopic rods 3, and the controller 4 are electrically connected to the controller 4. Both the multi-stage electric telescopic rod and the power motor 6 are powered by an external power source. At this time, the operator controls the controller 4 to adjust the multi-stage electric telescopic rod according to the size of the sewage sedimentation tank, so that the combined telescopic length of the rectangular crossbar 1 and the multi-stage electric telescopic rod 3 can be just right to be erected on the opening of the sewage sedimentation tank. Then, the rectangular crossbar 1 is placed on the opening of the sewage sedimentation tank, and the sludge scraping mechanism 2 is placed at the bottom of the sewage sedimentation tank. At this time, the controller 4 controls the power motor 6 to rotate, which in turn drives the transmission shaft 7 to rotate, which in turn drives the sludge scraping mechanism 2 to rotate. After the sludge scraping mechanism 2 rotates, it scrapes away the sludge at the bottom of the sludge sedimentation tank. Thus, the length of the sludge scraping device at the bottom of the sewage sedimentation tank can be automatically adjusted and installed for sewage sedimentation tanks of different sizes, without much manual adjustment, saving labor, and with short installation and adjustment time and high efficiency, thus improving the efficiency of sludge scraping at the bottom of the sewage sedimentation tank.

[0024] As a further improvement to the above embodiment, the sludge scraping mechanism 2 includes a rotating cylinder 201 and a scraper plate 202. Sludge scraper plates 202 are respectively provided on both sides of the rotating cylinder 201. The scraper plates 202 are detachably connected to the rotating cylinder 201, thus allowing for flexible replacement of appropriate scraper plates 202 according to the diameter of the sedimentation tank, improving the applicability of the device. A connecting rod 10 is provided at the upper end of the rotating cylinder 201, and the lower end of the connecting rod 10 is detachably connected to the upper end of the rotating cylinder 201. The upper end of the connecting rod 10 is detachably connected to the lower end of the drive shaft 7, allowing for flexible replacement of a suitable length of connecting rod 10 according to the depth of the sedimentation tank, enabling the scraper plate 202 to contact the bottom of the sewage sedimentation tank and scrape sludge, further improving the applicability of the device. With the above configuration, when the sludge scraping mechanism 2 rotates to perform sludge scraping, the rotating cylinder 201 drives the scraper plate 202 to swing, thereby scraping away the sludge at the bottom of the sewage sedimentation tank, achieving efficient sludge scraping of the bottom of the sewage sedimentation tank.

[0025] Furthermore, the lower end of the scraper 202 is provided with a long scraper rubber strip 11. The upper end of the long scraper rubber strip 11 is detachably connected to the lower end of the scraper 202. The long scraper rubber strip 11 is used to improve the scraping effect on the bottom of the sewage sedimentation tank, and also to protect the bottom of the scraper 202, thereby increasing the service life of the scraper 202. The detachable connection between the long scraper rubber strip 11 and the scraper 202 facilitates timely replacement of the long scraper rubber strip 11 when it is damaged. The lower end of the rotating cylinder 201 is provided with a short scraper rubber strip 12. The lower end of the rotating cylinder 201 is detachably connected to the upper end of the short scraper rubber strip 12. The short scraper rubber strip 12 is used to scrape away the sludge below the rotating cylinder 201. The detachable connection between the short scraper rubber strip 12 and the bottom end of the rotating cylinder 201 facilitates timely replacement of the short scraper rubber strip 12 when it is damaged.

[0026] Furthermore, the telescopic end of the multi-stage electric telescopic rod 3 is provided with a placement component 13, which is fixedly connected to the multi-stage electric telescopic rod 3. The placement component 13 consists of a horizontal block 22 and a vertical block 23. The end of the horizontal block 22 near the telescopic end of the multi-stage electric telescopic rod 3 is fixedly connected to the upper end of the vertical block 23. When the rectangular crossbar 1 is erected on the opening of the sewage sedimentation tank, the placement component 13 at the telescopic end of the multi-stage electric telescopic rod 3 contacts the edge of the opening of the sewage sedimentation tank and is placed on the edge of the opening. At this time, the horizontal block 22 is located at the upper end of the edge of the opening, and the vertical block 23 is close to the edge of the opening, thereby improving the stability of the rectangular crossbar 1 erected on the opening of the sewage sedimentation tank and improving the stability of the device.

[0027] Furthermore, the lower end of the horizontal block 22 and the side of the vertical block 23 away from the multi-stage electric telescopic rod 3 are both provided with anti-slip rubber surface 14, which improves the anti-slip performance of the horizontal block 22 and the vertical block 23 and further improves the stability of the device.

[0028] Furthermore, a water pump chamber 8 is provided inside the rectangular crossbar 1, and an electric water pump 9 is installed inside the water pump chamber 8. The electric water pump 9 is fixedly connected to the bottom of the water pump chamber 8. Two water outlet vertical pipes are provided below the rectangular crossbar 1. A water delivery pipe 15 is provided inside the rectangular crossbar 1. One end of the water delivery pipe 15 passes through the upper end of the water outlet vertical pipe and communicates with the water outlet vertical pipe 16. The water outlet end of the electric water pump 9 passes through the water pump chamber 8 and communicates with the other end of the water delivery pipe 15. The water inlet end of the electric water pump 9 passes through the water pump chamber 8. The cavity 8 is connected to an external water source pipe. When the sludge scraping work begins, the water pump 9 is connected to an external power source. At this time, the water pump 9 is controlled by the controller 4 to work. The water pump 9 delivers clean water to the water supply pipe 15, and then the water supply pipe 15 delivers it to the outlet vertical pipe 16. The outlet vertical pipe 16 then sprays the clean water into the bottom of the sewage sedimentation tank. This allows the sludge that is relatively dry and hard and sticks tightly to the bottom of the sedimentation tank to be softened by water spraying during the sludge scraping process of the sludge scraping mechanism 2. This allows the dry and hard sludge to be scraped off, thereby improving the sludge scraping efficiency at the bottom of the sewage sedimentation tank.

[0029] Furthermore, the lower end of the motor cavity 5 is provided with a through hole 17, and a bearing 18 is provided in the through hole 17. The transmission shaft 7 passes through the bearing 18 and is fixedly connected to the output shaft of the power motor 6 to ensure the normal operation of the transmission shaft 7. A limiting turntable 19 is sleeved on the part of the transmission shaft 7 that passes through the bearing 18 and is placed in the motor cavity 5. The limiting turntable is used to restrict the downward movement of the transmission shaft 7 to prevent the transmission shaft from falling off, improve the stability of the transmission shaft 7, and ensure the normal rotation of the transmission shaft 7.
