Description

Technical Field

[0001] The utility model relates to the technical field of driving sludge scrapers, in particular to a suspended center driving sludge scraper. Background Technique

[0002] A sludge scraper is a machine that clears sludge from a river channel and is used in large-diameter circular sedimentation tanks in urban sewage treatment plants, water treatment plants, and industrial wastewater treatment to remove the sludge settled at the bottom of the tank and skim the scum on the surface of the tank. During the sludge scraping process of the existing sludge scraper, due to the different sizes of sludge ponds, the current sludge scraper cannot scrape according to the sludge pond, and the sludge scraping treatment effect is not ideal.

[0003] After retrieval, a suspended center driving sludge scraper (publication number: CN216092365U) disclosed in the prior art records that "the output end of the driving device is rotatably connected to a rotating shaft, a rotating thread is fixedly arranged on the outer side of the middle part of the rotating shaft, a self-rotating machine is rotatably connected to the outer side of the rotating thread, hydraulic telescopic devices are welded on both sides of the self-rotating machine, a first sludge scraping plate is fixedly arranged at the output end of the hydraulic telescopic device, and a round shaft ball is fixedly arranged at the bottom end of the rotating shaft 4."; this sludge scraper can clean and scrape the sludge at the bottom end inside the sludge pond by setting a controller, a rotating shaft, and a second sludge scraping plate. When the rotating shaft rotates, the self-rotating machine in the middle of the rotating shaft rotates counterclockwise with the rotating shaft to scrape the sludge on both sides of the sludge pond. At the same time, a hydraulic telescopic device, a first sludge scraping plate, and a sludge thickness detector are set to automatically measure the sludge thickness, so that the hydraulic telescopic device and the first sludge scraping plate can reasonably arrange the sludge cleaning work, which can not only save resources, is beneficial to the sedimentation of dirt, and avoid the floating of sludge. However, when cleaning a sludge pond with a large diameter, the distance between the first sludge scraping plate and the rotating shaft will be enlarged, resulting in the lack of a corresponding auxiliary support structure for the first sludge scraping plate. Then, when the first sludge scraping plate cleans the sludge, structural deformation and damage are likely to occur among the first sludge scraping plate, the hydraulic telescopic device, and the rotating shaft. Moreover, when there is a large amount of sludge and the resistance received by the first sludge scraping plate is large, the three may even break. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Refer to Figures 1 to 4As shown in the figure, the utility model provides a suspended center-driven sludge scraper, which includes a horizontal suspension plate 10 and a moving plate 12. The horizontal suspension plate 10 is fixedly connected to the upper surface of the sludge pond 1. The surface of the horizontal suspension plate 10 is fixedly connected with a hydraulic rod 13 and a main motor 14 respectively. The output shaft of the main motor 14 is connected to a transmission rod 3 through a coupling. The upper end of the transmission rod 3 is movably connected to the horizontal suspension plate 10 through a sealed bearing. The lower end of the transmission rod 3 is fixedly connected to an auger 2 through a coupling. The auger 2 is movably connected to the sludge outlet at the bottom of the sludge pond 1. At the same time, the telescopic rod of the hydraulic rod 13 is fixedly connected to the moving plate 12. The upper surface of the moving plate 12 is symmetrically connected with auxiliary motors 11. The upper surface of the moving plate 12 is symmetrically provided with movable grooves. The movable grooves are movably connected with driving wheels 9 through sealed bearings. The driving wheels 9 are connected to the auxiliary motors 11 through couplings. The lower surface of the moving plate 12 is symmetrically provided with rotating grooves. The sides of the rotating grooves communicate with the movable grooves. A rotating ring 8 is slidably connected in the rotating grooves. The inner side surface of the rotating ring 8 is meshed with the driving wheels 9 through tooth grooves. At the same time, the lower surface of the rotating ring 8 is fixedly connected with a main scraper 7. The side surface of the main scraper 7 is fixedly connected with a side scraper 4 through a fixing plate 5.

[0020] In this embodiment, when the sludge pond 1 needs to be scraped, first turn on the switch of the main motor 14. The main motor 14 synchronously drives the fixedly connected transmission rod 3 and auger 2 through the coupling, so that the sludge at the bottom of the sludge pond 1 can be quickly discharged from the sludge outlet. Then turn on the combined switch of the two groups of auxiliary motors 11. The two groups of auxiliary motors 11 can rotate synchronously. The output shafts of the auxiliary motors 11 drive the driving wheels 9 to rotate through the couplings. The driving wheels 9 drive the rotating ring 8 to rotate through the meshed tooth grooves. The rotating ring 8 drives the fixedly connected main scraper 7, reinforcement components 6 and side scrapers 4 to rotate synchronously, so that the side scrapers 4 can clean the sludge on the side wall of the sludge pond 1 accordingly. Then the sludge can fall to the bottom of the sludge pond 1 for subsequent discharge. After that, turn on the switch of the hydraulic rod 13. The telescopic rod of the hydraulic rod 13 pushes the moving plate 12 to move downward at a low speed, which can enhance the cleaning effect of the side scraper 4 on the side wall of the sludge pond 1. And when the bent part of the main scraper 7 touches the sludge at the bottom of the sludge pond 1, the rotating main scraper 7 can push the sludge at the edge of the bottom of the sludge pond 1 towards the middle, thereby assisting in enhancing the effect of the auger 2 in transporting sludge, improving the efficiency of the sludge scraper in cleaning sludge. And the lengths of the main scraper 7 and the side scraper 4 are appropriate, and the overall quality is hard and not easy to bend and deform. Therefore, the probability of component damage during the use of the sludge scraper can be effectively reduced.

[0021] As a preferred embodiment, the moving plate 12 is in a cross-shaped structure. Two groups of auxiliary motors 11 are fixedly connected to the opposite ends of the moving plate 12. The other two ends of the moving plate 12 are symmetrically connected with two groups of guide rods 15. Both groups of guide rods 15 are in a cylindrical structure. At the same time, the size of the moving plate 12 is smaller than the inner diameter of the sludge pond 1.

[0022] In this embodiment, as Figure 1, Figure 2 and Figure 3 , the auxiliary motor 11 adopts a servo motor, thus ensuring that the two groups of auxiliary motors 11 can rotate synchronously at a low speed. Moreover, the size of the moving plate 12 is smaller than the inner diameter of the sludge tank 1. Therefore, the moving plate 12 can push the main scraper 7 and the side scraper 4 to move downward synchronously, increasing the cleaning range of the sludge scraper. The setting of the guide rod 15 can assist in enhancing the stability of the moving plate 12 during movement.

[0023] As a preferred embodiment, the telescopic rod of the hydraulic rod 13 is fixedly connected to the upper surface of the moving plate 12 near the auxiliary motor 11. The hydraulic rod 13 and the guide rod 15 are combined in a square distribution, and the two sets of movable grooves opened in the moving plate 12 are both square structures.

[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 3 , the positional distribution of the hydraulic rod 13 and the guide rod 15 can effectively enhance the connection effect between the horizontal suspension plate 10 and the moving plate 12, reduce the probability of shaking during the movement of the moving plate 12, and ensure that the moving plate 12 can support the rotating ring 8, the main scraper 7 and the side scraper 4 to rotate stably.

[0025] As a preferred embodiment, the rotating groove opened on the lower surface of the moving plate 12 is in a fan-shaped ring structure, the cross-section of the rotating groove is in a convex shape structure, and the sizes of the rotating groove and the rotating ring 8 are adapted. The rotating ring 8 is in a circular ring structure, and tooth grooves are evenly opened on the inner arc surface of the rotating ring 8.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 , the sizes of the rotating groove and the rotating ring 8 being adapted can assist in enhancing the stability of the rotating ring 8 during rotation. Moreover, the tooth grooves opened on the inner arc surface of the rotating ring 8 face the driving wheel 9, which can assist in enhancing the meshing stability between the driving wheel 9 and the rotating ring 8.

[0027] As a preferred embodiment, the main scraper 7 is composed of a main body part and a mounting part. The mounting part is in a fan-shaped ring structure, and the sizes of the mounting part and the opening of the rotating groove are adapted. The main body part is in an L-shaped structure, and the inclined surface of the bent part of the main body part is parallel to the inclined surface of the bottom of the inner cavity of the sludge tank 1.

[0028] In this embodiment, as Figure 1 and Figure 4 , the structural setting of the mounting part enables the main scraper 7 to rotate synchronously with the rotating plate in the rotating groove, thereby enhancing the stability of the synchronous rotation of the rotating ring 8 and the main scraper 7. At the same time, the inclined setting of the bent part of the main body part can assist in enhancing the cleaning effect of the main scraper 7 on the bottom of the sludge tank 1.

[0029] As a preferred embodiment, the fixing plate 5 fixedly connected to the side of the main scraper 7 is rectangular in structure, while the side scraper 4 fixedly connected to the fixing plate 5 by bolts is cuboid in structure, and the end face of the side scraper 4 is trapezoidal with a right angle, and the two groups of side scrapers 4 are centrally symmetrically distributed in the sludge pit 1 by the main scraper 7, and at the same time, the inside of the side scraper 4 is hollow.

[0030] In this embodiment, as Figure 1 and Figure 4 , the hollow structure of the side scraper 4 can not only reduce the material consumption of the side scraper 4, but also reduce the weight of the side scraper 4, reduce the load on the rotating ring 8 and the moving plate 12. At the same time, the inclined surface structure of the side scraper 4 can assist in enhancing the cleaning effect of the side scraper 4 on the side wall of the sludge pit 1.

[0031] As a preferred embodiment, the cross-suspension plate 10 is cross-shaped in structure, the size of the cross-suspension plate 10 is larger than that of the moving plate 12, and guide holes are correspondingly opened on the surface of the cross-suspension plate 10 at positions corresponding to the guide rods 15. The reinforcing component 6 fixedly connected to the inner side of the main scraper 7 is linear in structure, and the reinforcing component 6 is composed of a reinforcing rod and a limiting ring. At the same time, the reinforcing rod is cylindrical in structure, and the limiting ring is circular in structure, and the limiting ring is sleeved on the surface of the transmission rod 3.

[0032] In this embodiment, as Figure 1 and Figure 2 , the size setting of the cross-suspension plate 10 enables the cross-suspension plate 10 to be stably fixedly connected to the upper surface of the sludge pit 1, providing a support point for the subsequent cleaning of the sludge scraper. The setting of the reinforcing component 6 can not only assist in enhancing the structural strength between the two groups of main scrapers 7, but also assist in enhancing the stability of the transmission rod 3 during rotation.

[0033] The suspended center drive sludge scraper of the present utility model, through the cooperation of the cross-suspension plate 10, the hydraulic rod 13, the moving plate 12, the rotating ring 8, the main scraper 7 and the side scraper 4, enables the sludge scraper to gradually clean the sludge from top to bottom, and can effectively enhance the structural strength of the main scraper 7 and the side scraper 4, avoiding damage during the sludge cleaning process. At the same time, the cooperation of the main motor 14, the transmission rod 3 and the auger 2 enables the sludge in the sludge pit 1 to be quickly discharged, improving the working efficiency of the sludge scraper.

[0034] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
