Description

Technical Field

[0001] This utility model relates to the field of sludge scraper technology, and in particular to a sludge scraper for environmental engineering. Background Technology

[0002] Environmental engineering is an interdisciplinary field that integrates engineering technology and ecological protection, focusing on the treatment of water pollution, air pollution, soil pollution and solid waste. Sludge scrapers are used to scrape off the sludge deposited on the inner wall of sedimentation tanks, making it easier to discharge the sludge from the sedimentation tank. They can operate continuously or intermittently and are widely used in environmental engineering scenarios such as sewage treatment plants and industrial wastewater treatment stations.

[0003] In the prior art, when the sludge scraper is working, the motor of the sludge scraper drives the scraper blade to slide along the inner wall of the sedimentation tank. The scraper blade can scrape the sludge settled at the bottom of the tank from the side to the center, so that the sludge can be discharged through the sludge discharge pipe.

[0004] The above-mentioned and existing technologies have the following drawbacks: During the intermittent operation of the sludge scraper, since the height of the scraper blade is fixed, when too much sludge accumulates in the sedimentation tank, the sludge will generate a large resistance to the moving scraper blade, causing the scraper blade to be difficult to move normally and get stuck, thus reducing the practicality of the scraper blade.

[0005] Therefore, a sludge scraper for environmental engineering is proposed. Utility Model Content

[0006] The purpose of this invention is to solve the problem that when too much sludge accumulates in the sedimentation tank, the fixed height of the scraper blade causes significant resistance to the moving scraper blade, making it difficult for the scraper blade to move normally and causing it to jam. Therefore, this invention proposes a scraper blade for environmental engineering.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a sludge scraper for environmental engineering, comprising a sedimentation tank, a valve pipe fixedly connected to the lower surface of the sedimentation tank, a support plate fixedly mounted on the inner wall of the sedimentation tank, a drive motor fixedly mounted on the upper surface of the support plate, a transmission shaft fixedly mounted through the output end of the drive motor passing through the support plate, a sliding tube slidably fitted on the surface of the transmission shaft, a sludge scraper fixedly mounted on the outer circumference of the sliding tube, an electric push rod fixedly mounted on the upper surface of the support plate, a connecting rod slidably passing through the support plate, the connecting rod being fixedly connected to the output end of the electric push rod, a retaining frame fixedly mounted at the lower end of the connecting rod, the retaining frame being rotatably connected to the sliding tube, a fixing plate fixedly mounted on the upper surface of the sedimentation tank, and a water pumping pipe fixedly mounted inside the fixing plate.

[0008] The effect achieved by the above components is as follows: by setting up components such as electric actuators, connecting rods, clamping frames, sliding tubes, and scraper blades, when using a sludge scraper in environmental engineering, the height of the scraper blade can be adjusted by controlling the working state of the electric actuator, so that the scraper blade can scrape off the sludge normally, ensuring the normal operation of the sludge scraper and improving the practicality of the scraper blade.

[0009] Preferably, a spiral plate is fixedly mounted on the surface of the drive shaft, and the spiral plate abuts against the inner wall of the sedimentation tank.

[0010] The effect achieved by the above components is that the spiral plate on the surface of the drive shaft can rotate with the drive shaft, and the spiral plate will transport the sludge downward, thereby accelerating the entry of the sludge into the valve pipe.

[0011] Preferably, one end of the pumping pipe is fixedly connected to a folded pipe, the lower end of the folded pipe is fixedly connected to a transmission plate, a servo motor is fixedly mounted on the upper surface of the fixed plate, a screw that is rotatably connected to the fixed plate is fixedly mounted on the output end of the servo motor, and a threaded pipe that is fixedly connected to the transmission plate is threadedly connected to the circumferential surface of the screw.

[0012] The aforementioned components achieve the following effects: When the pumping position needs to be adjusted, an external water pump is connected to the pumping pipe, and a servo motor is controlled to drive the screw to rotate. The screw will drive the threaded tube to move vertically via the thread, and the threaded tube will drive the transmission plate to move synchronously. The movement of the transmission plate will stretch or compress the folded tube. When there is a lot of sludge in the sedimentation tank, the transmission plate will move upward to increase the distance between the transmission plate and the bottom of the sedimentation tank, preventing the sludge at the bottom of the sedimentation tank from being sucked in. When there is less sludge in the sedimentation tank, the transmission plate will move downward, thereby enabling sufficient pumping of clean water.

[0013] Preferably, a limiting plate slides through the fixed plate, and the limiting plate is fixedly connected to the transmission plate.

[0014] The effect achieved by the above components is that during the movement of the transmission plate, the limiting plate will move synchronously with the transmission plate, and the limiting plate can restrict the movement path of the transmission plate.

[0015] Preferably, the surface of the limiting plate is provided with a scale groove.

[0016] The effect achieved by the above components is that the scale groove makes it easy for workers to judge the moving distance of the transmission plate.

[0017] Preferably, a baffle is fixedly mounted on the upper surface of the limiting plate.

[0018] The effect achieved by the above components is that the baffle can prevent the limiting plate from coming out of the fixed plate.

[0019] Preferably, the drive shaft has a regular hexagonal prism structure.

[0020] The effect achieved by the above components is that the drive shaft with the regular hexagonal prism structure can not only drive the slide tube to rotate normally, but also make the slide tube slide in the vertical direction.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this utility model, by setting up components such as electric actuator, connecting rod, clamping frame, sliding tube and scraper, when using a sludge scraper in environmental engineering, the height of the scraper can be adjusted by controlling the working state of the electric actuator, so that the scraper can scrape off the sludge normally, ensuring the normal operation of the sludge scraper and improving the practicality of the scraper.

Detailed Implementation

[0028] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0030] like Figures 1-4As shown, this utility model provides a sludge scraper for environmental engineering, including a sedimentation tank 1. A valve pipe 2 is fixedly connected to the lower surface of the sedimentation tank 1. A support plate 3 is fixedly mounted on the inner wall of the sedimentation tank 1. A drive motor 4 is fixedly mounted on the upper surface of the support plate 3. A transmission shaft 5 is fixedly mounted through the support plate 3 at the output end of the drive motor 4. A sliding tube 6 is slidably sleeved on the surface of the transmission shaft 5. A sludge scraper 7 is fixedly mounted on the outer circumference of the sliding tube 6. An electric push rod 8 is fixedly mounted on the upper surface of the support plate 3. A connecting rod 9 slides through the support plate 3 and is fixedly connected to the output end of the electric push rod 8. A retaining frame 10 is fixedly mounted on the lower end of the connecting rod 9. The retaining frame 10 is rotatably connected to the sliding tube 6. A fixed plate 12 is fixedly mounted on the surface, and a water pumping pipe 13 is fixedly mounted inside the fixed plate 12. By setting components such as electric push rod 8, connecting rod 9, clamping frame 10, sliding pipe 6 and sludge scraper 7, when using the sludge scraper in environmental engineering, the height of the sludge scraper 7 can be adjusted by controlling the working state of the electric push rod 8, so that the sludge scraper 7 can scrape the sludge normally, ensuring the normal operation of the sludge scraper and improving the practicality of the sludge scraper 7. A spiral plate 11 is fixedly mounted on the surface of the drive shaft 5. The spiral plate 11 abuts against the inner wall of the sedimentation tank 1. The spiral plate 11 on the surface of the drive shaft 5 can rotate with the drive shaft 5, and the spiral plate 11 will transport the sludge downward, thereby accelerating the sludge to enter the valve pipe 2.

[0031] One end of the pumping pipe 13 is fixedly connected to a folded pipe 14, and the lower end of the folded pipe 14 is fixedly connected to a transmission plate 15. A servo motor 16 is fixedly mounted on the upper surface of the fixed plate 12, and a screw 17 rotatably connected to the fixed plate 12 is fixedly mounted on the output end of the servo motor 16. A threaded pipe 18, which is fixedly connected to the transmission plate 15, is threadedly connected to the circumferential surface of the screw 17. When it is necessary to adjust the pumping position, an external pumping pump is connected to the pumping pipe 13, and the servo motor 16 is controlled to drive the screw 17 to rotate. The screw 17 will drive the threaded pipe 18 to move vertically through the thread, and the threaded pipe 18 will drive the transmission plate 15 to move synchronously. The movement of the transmission plate 15 will cause the folded pipe 14 to be stretched or compressed. When there is a lot of sludge in the sedimentation tank 1, the transmission plate 15 will move upward to increase the distance between the transmission plate 15 and the bottom of the sedimentation tank 1, thus preventing sedimentation. Sludge from the bottom of the sedimentation tank 1 is sucked in. When there is less sludge in the sedimentation tank 1, the transmission plate 15 moves downward, thereby fully sucking up the clean water. A limiting plate 19 slides through the fixed plate 12. The limiting plate 19 is fixedly connected to the transmission plate 15. During the movement of the transmission plate 15, the limiting plate 19 moves synchronously with the transmission plate 15. The limiting plate 19 can restrict the movement path of the transmission plate 15. A scale groove 20 is opened on the surface of the limiting plate 19. The scale groove 20 can facilitate the staff to judge the movement distance of the transmission plate 15. A baffle 21 is fixedly installed on the upper surface of the limiting plate 19. The baffle 21 can prevent the limiting plate 19 from falling out of the fixed plate 12. The transmission shaft 5 has a regular hexagonal prism structure. The regular hexagonal prism structure of the transmission shaft 5 can ensure the normal rotation of the slide tube 6, and also allow the slide tube 6 to slide in the vertical direction.

[0032] The overall working principle is as follows: When a sludge scraper is needed in environmental engineering, the drive motor 4 drives the transmission shaft 5 to rotate, and the slide tube 6 and scraper 7 rotate synchronously to scrape the sludge from the bottom of the tank from the edge to the center, and then discharge it through the valve pipe 2. During this process, the spiral plate 11 on the surface of the transmission shaft 5 rotates with the transmission shaft 5, and the spiral plate 11 will transport the sludge downward, thereby accelerating the sludge into the valve pipe 2. When there is a lot of sludge in the sedimentation tank 1, the electric push rod 8 is controlled to push the connecting rod 9 and the clamping frame 10 to move vertically, thereby driving the slide tube 6 to slide along the surface of the transmission shaft 5. The slide tube 6 will drive the scraper 7 to move, thereby adjusting the height of the scraper 7 in time, so that the scraper 7 can scrape the sludge normally and ensure that the sludge scraper can operate normally. The transmission shaft 5 with a regular hexagonal prism structure can not only drive the slide tube 6 to rotate normally, but also make the slide tube 6 slide vertically.

[0033] When the pumping position needs to be adjusted, the external pump is connected to the pumping pipe 13, and the servo motor 16 is controlled to drive the screw 17 to rotate. The screw 17 will drive the threaded pipe 18 to move vertically through the thread. The threaded pipe 18 will drive the transmission plate 15 to move synchronously. The movement of the transmission plate 15 will stretch or compress the folded pipe 14. When there is a lot of sludge in the sedimentation tank 1, the transmission plate 15 will move upward to increase the distance between the transmission plate 15 and the bottom of the sedimentation tank 1, so as to prevent the sludge at the bottom of the sedimentation tank 1 from being sucked in. When there is less sludge in the sedimentation tank 1, the transmission plate 15 will move downward, so as to fully pump out the clean water. During the movement of the transmission plate 15, the limiting plate 19 will move synchronously with the transmission plate 15. The limiting plate 19 can restrict the movement path of the transmission plate 15, and the scale groove 20 can make it convenient for the staff to judge the movement distance of the transmission plate 15. The baffle 21 can prevent the limiting plate 19 from falling out of the fixed plate 12.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
