Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, and more specifically, to an influent sludge removal device for wastewater treatment plants. Background Technology

[0002] In wastewater treatment plants, the main function of the influent sludge removal device is to remove large particulate impurities (such as floating matter, plant debris, and gravel) from the water, preventing these solid materials from clogging or damaging subsequent treatment equipment (such as pumps, pipelines, and reaction tanks), and improving the efficiency of subsequent treatment. Among these, bar screen sludge removal is the most common treatment equipment. In the treatment of industrial wastewater such as textiles, the wastewater contains some mud or similar solid impurities, as well as some linear impurities such as chemical fibers. When using influent sludge removal equipment to remove sludge from this wastewater, the surface of the bar screen often becomes entangled by these linear impurities, and mud is retained, resulting in poor sludge removal effect of the influent sludge removal equipment during operation.

[0003] Therefore, there is an urgent need for an influent sludge removal device for wastewater treatment plants that can effectively remove sludge from wastewater while ensuring the effective operation of the sludge removal equipment and improving work efficiency. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an influent sludge removal device for sewage treatment plants, so as to solve the technical defects in the above-mentioned background technology.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A sludge removal device for the influent of a wastewater treatment plant includes a mounting frame, a drive motor disposed on the upper surface of the mounting frame, and a sludge removal mechanism disposed inside the mounting frame and cooperating with the drive motor. The sludge removal mechanism includes a rotating shaft connected to the drive motor, a transmission belt that is in annular transmission cooperation with the rotating shaft, sludge removal components that are uniformly and equidistantly installed on the surface of the transmission belt, a scraping structure located inside the mounting frame and above the sludge removal components and in contact with each other, and a wiping structure disposed behind the scraping structure and cooperating with the sludge removal components.

[0007] The slag removal component includes a frame plate vertically mounted on the surface of the transmission belt, a rectangular groove integrally formed inside the frame plate, a sludge-blocking frame adapted to and movably fitted with the rectangular groove, an adjusting telescopic rod on the upper surfaces of the left and right sides of the sludge-blocking frame, a limiting spring wound around the upper half of the adjusting telescopic rod and connected to the rectangular groove, a filter screen movably detachable on the lower surface of the sludge-blocking frame, a U-shaped mounting frame integrally formed on the front surface of the frame plate, a mounting rod horizontally mounted inside the U-shaped mounting frame, and cleaning hooks evenly spaced on the surface of the mounting rod.

[0008] The adjustable telescopic rods are arranged in pairs, and their maximum extension range is such that the upper surface of the debris-blocking frame moves downward until it is flush with the lower surface of the rectangular trough, thereby maximizing the collection of impurities in the sewage.

[0009] The scraping structure includes a support rod horizontally mounted inside the rear side of the mounting frame and scraping plates evenly spaced on the surface of the support rod.

[0010] The removal structure includes a rotating rod horizontally mounted inside the mounting frame and located behind the support rod. The surface of the rotating rod is provided with a plurality of anti-clogging structures installed in a uniform and equidistant manner. The anti-clogging structure includes a mounting shaft seat that fits into the surface of the rotating rod, a movable spring rod installed in a uniform and equidistant manner on the surface of the mounting shaft seat, a spring strip wrapped around the surface of the movable spring rod, and a clearing ball at the end of the movable spring rod.

[0011] As a further embodiment of this utility model, the number of scraping plates is the same as that of the cleaning hooks and they are arranged in a corresponding manner. The contact surface between the scraping plates and the cleaning hooks is an arc surface and has a rough structure, which is used to wipe away the mud retained on the surface of the cleaning hooks when they come into contact with them, thereby enhancing the sludge removal effect of the cleaning hooks on the sludge in the subsequent sewage.

[0012] As a further embodiment of this utility model, the rotating rod is engaged with the drive motor on the side closest to it.

[0013] As a further embodiment of this utility model, each set of anti-clogging structures is set at the midpoint of the position of the adjacent cleaning hook to prevent the middle position of the adjacent cleaning hook from becoming blocked by impurities, thus making it difficult to remove slag.

[0014] As a further embodiment of this utility model, when the movable spring rod is in operation, it passes through the middle of the adjacent cleaning hooks together with the cleaning ball connected to its end, so as to realize the normal gap between the two cleaning hooks and prevent the gap from being blocked.

[0015] As a further embodiment of this utility model, the unblocking ball is made of fluororubber, and the unblocking ball and the movable spring rod are configured with a detachable structure, which allows the unblocking ball to be flexibly replaced after wear.

[0016] As a further embodiment of this utility model, the cleaning hook is configured with an arc-shaped structure.

[0017] Compared with a traditional influent sludge removal device used in sewage treatment plants, this utility model has the following advantages:

[0018] This invention incorporates uniformly distributed slag removal components on the transmission belt. The expandable design of the frame plate and the debris-blocking frame maximizes slag removal from wastewater in conjunction with the cleaning hook. The filter screen on the lower surface of the debris-blocking frame is removable, allowing for the replacement of different pore sizes to remove various particulate matter from the wastewater, thus further improving the slag removal efficiency of wastewater influent in wastewater treatment plants.

[0019] This utility model also includes a scraping structure and a brushing structure that work in conjunction with the slag removal component. These structures enable contact scraping of mud and other highly adhesive slag residues retained on the surface of the cleaning hooks. Simultaneously, by utilizing the anti-clogging structure and its corresponding placement at the center of adjacent cleaning hooks, the anti-clogging structure, in conjunction with the rotational trajectory of the movable spring rod and the clogging ball, breaks up the slag residues retained between adjacent cleaning hooks. This improves the effectiveness of the cleaning hooks in treating residual slag in wastewater. Attached Figure Description

Detailed Implementation

[0030] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0031] like Figures 1-7 As shown, this utility model provides a technical solution for an influent sludge removal device for a sewage treatment plant:

[0032] As shown in the figure, an influent slag removal device for a sewage treatment plant includes a frame 1, a drive motor 2 disposed on the upper surface of the frame 1, and a slag removal mechanism 3 disposed inside the frame 1 and cooperating with the drive motor 2. The slag removal mechanism 3 includes a rotating shaft 31 connected to the drive motor 2, a transmission belt 32 that is in a ring-shaped transmission cooperation with the rotating shaft 31, slag removal components 33 that are uniformly and equidistantly installed on the surface of the transmission belt 32, a scraping structure 34 located inside the frame 1 and above the slag removal components 33 and in contact with each other, and a brushing structure 35 disposed behind the scraping structure 34 and cooperating with the slag removal components 33.

[0033] The slag removal component 33 includes a frame plate 331 installed vertically on the surface of the transmission belt 32, a rectangular groove 332 formed as an integral structure inside the frame plate 331, a sludge-blocking frame 333 adapted to and movably fitted with the rectangular groove 332, an adjusting telescopic rod 334 on the upper surfaces of the left and right sides of the sludge-blocking frame 333, a limiting spring 335 wrapped around the upper half of the adjusting telescopic rod 334 and connected to the rectangular groove 331, a filter screen 336 on the lower surface of the sludge-blocking frame 333 and movably detachable, a U-shaped mounting frame 337 formed as an integral structure on the front surface of the frame plate 331, a mounting rod 338 horizontally mounted inside the U-shaped mounting frame 337, and cleaning hooks 339 evenly spaced on the surface of the mounting rod 338.

[0034] The telescopic rods 334 are arranged in pairs, and their maximum extension range is such that when the debris-blocking frame 333 moves downward, the upper surface of the debris-blocking frame is flush with the lower surface of the rectangular trough 332, thereby maximizing the collection of impurities in the sewage.

[0035] The scraping structure 34 includes a support rod 341 that is horizontally mounted inside the rear side of the mounting frame 1 and a scraping plate 342 that is evenly and equidistantly arranged on the surface of the support rod 341.

[0036] The removal structure 35 includes a rotating rod 351 that is horizontally mounted inside the mounting frame 1 and located behind the support rod 341. The surface of the rotating rod 351 is provided with a plurality of anti-clogging structures installed in a uniform and equidistant manner. The anti-clogging structure includes a mounting shaft seat 352 that fits into the surface of the rotating rod 351, a movable spring rod 353 that is installed in a uniform and equidistant manner on the surface of the mounting shaft seat 352, a spring strip 354 that is wound around the surface of the movable spring rod 353, and a clearing ball 355 at the end of the movable spring rod 353.

[0037] The number of scraper plates 342 is the same as that of cleaning hooks 339 and they are arranged in a corresponding manner. The contact surface between the scraper plates 342 and the cleaning hooks 339 is an arc surface with a rough structure. This is to enable the scraper plates 342 to wipe away the mud retained on the surface of the cleaning hooks when they come into contact with them, thereby enhancing the cleaning hooks' ability to remove sludge from the wastewater.

[0038] The rotating rod 351 is connected to the drive motor 2 via transmission.

[0039] Each anti-clogging structure is set at the midpoint of the adjacent cleaning hook 339 to prevent slag removal difficulties caused by impurities clogging the middle position of adjacent cleaning hooks.

[0040] When in operation, the movable spring rod 353, together with the unblocking ball 355 connected to its end, passes through the middle of the adjacent cleaning hooks 339 to achieve a normal gap between the two cleaning hooks and prevent the gap from becoming blocked.

[0041] The unblocking ball 355 is made of fluororubber. The unblocking ball 355 and the movable spring rod 353 are designed with a movable and detachable structure, which allows the unblocking ball to be flexibly replaced after wear.

[0042] The cleaning hook 339 has an arc-shaped structure.

[0043] The specific implementation principle is as follows: When using the inlet sludge removal device, the equipment is powered on and started. The rotating shaft 31 and the rotating rod 351 are both powered on and started by the drive motor 2, and rotate. The cleaning hook 339 hooks up and intercepts the sludge in the sewage. At the same time, the sludge-collecting frame 333 also collects the sludge in the sewage. With the rotation of the transmission belt 32, the sludge is hooked from the sewage and enters the interior of the upper part of the mounting frame 1 for centralized collection. Since the lower surface of the sludge-collecting frame 333 is equipped with a filter screen 336, the collected sludge can be filtered to prevent the sewage from being carried up and increasing the overall operation of the sludge removal mechanism 3. The sludge removal component 33 rotates to contact the scraping structure 34. Then, the cleaning hook 339 will come into contact with the scraper plate 342, thereby scraping away the dirt adhering to the back of the cleaning hook 339 under the contact of the scraper plate 342, thus ensuring that there is no dirt adhering to the back of the cleaning hook 339, and strengthening the operation and use of the cleaning hook 339. On the other hand, the rotating rod 351 rotates under the action of the drive motor 2, thereby driving the anti-clogging structure set on its surface to rotate. The movable spring rod 353 will extend to the center position between adjacent cleaning hooks 339 during the rotation, and work with the unclogging ball 335 to break up the strip-shaped and ribbon-shaped slag stuck between adjacent cleaning hooks 339, thereby strengthening the slag removal operation of the sewage inlet.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
