Description

Technical Field

[0001] This utility model relates to the technical field of sludge treatment equipment, and in particular to an anti-clogging sludge dewatering and drying device. Background Technology

[0002] In environmental engineering and wastewater treatment plants, sludge treatment is a crucial step, with dewatering and drying being the core steps for reducing sludge volume and achieving sludge reduction and resource utilization. Existing sludge dewatering and drying devices mostly use drum drying. However, in actual operation, when sludge enters the drum through the feed hopper, the presence of numerous impurities (dried branches, leaves, stones, etc.) can cause drum blockage or even damage, affecting drum efficiency and consequently impacting sludge dewatering and drying efficiency.

[0003] To address the aforementioned technical deficiencies, a solution is proposed: by installing a filter plate inside the feed hopper, the filter plate can filter impurities in the sludge, thereby preventing impurities from entering the dryer drum. This avoids clogging or even damage to the dryer drum due to impurities, ensuring the working efficiency of the dryer drum and the dewatering and drying efficiency of the sludge.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1: The application background of this utility model is based on the fact that when dewatering and drying sludge, the sludge enters the drum through the feed hopper. Since the sludge contains a large number of impurities (dried branches, leaves, stones, etc.), the large number of impurities may cause the drum to be blocked or even damaged, thereby affecting the working efficiency of the drum and thus affecting the dewatering and drying efficiency of the sludge. The technical solution of this utility model is to solve the problem of how to prevent impurities (dried branches, leaves, stones, etc.) in the sludge from entering the drum and avoid the drum blockage or even damage. Please see Figures 1-2As shown, this embodiment is an anti-clogging sludge dewatering and drying device, including: a dewatering and drying assembly 100, including a base 101, two sets of connecting rings 102 symmetrically fixed to the top of the base 101, two sets of bearings 103 correspondingly installed inside the two sets of connecting rings 102, a dryer cylinder 104 fixed inside the two sets of bearings 103, a feed cylinder 108 movably installed at the end of the dryer cylinder 104, and a feed hopper 109 fixed to the outer wall of the feed cylinder 108; an anti-clogging assembly 200, including a limiting frame 201 fixed inside the feed cylinder 108, a filter plate 202 placed on the top of the limiting frame 201, and the feed hopper 109... The L-shaped strip 110 is fixed to the top of the base 101. A rotating gear 105 is fixed to the outer wall of the dryer cylinder 104. A motor 106 is installed on the top of the base 101. A drive gear 107 that meshes with the rotating gear 105 is fixed to the output end of the motor 106. A hanging ear 203 that is attached to the top of the feed hopper 109 is fixed to the top of the filter plate 202. A threaded hole 204 is opened on the outer wall of the hanging ear 203. A locking hole 205 is opened on the outer wall of the feed hopper 109. A threaded rod 206 is connected to the threaded hole 204. A rotating shaft 207 is fixed to one end of the threaded rod 206. The other end of the threaded rod 206 is locked inside the locking hole 205. By placing the filter plate 202 into the feed hopper 109, the limiting frame 201 initially limits and fixes the filter plate 202. Then, the rotating shaft 207 drives the threaded rod 206 to move in the threaded hole 204. When one end of the threaded rod 206 is engaged in the locking hole 205, the filter plate 202 is finally fixed. The filter plate 202 can filter impurities in the sludge, thereby preventing impurities in the sludge from entering the dryer cylinder 104. This prevents the dryer cylinder 104 from being blocked or even damaged by impurities, ensuring the working efficiency of the dryer cylinder 104 and the dewatering and drying efficiency of the sludge.

[0018] Example 2: Please refer to Figure 1 , Figure 3 , Figure 4As shown, this embodiment is an anti-clogging sludge dewatering and drying device, which also includes a cleaning component 300. The cleaning component 300 includes a cleaning ring 301 movably disposed inside the dryer cylinder 104, a fixing ring 303 movably sleeved outside the dryer cylinder 104, and a connecting rod 302 fixed between the cleaning ring 301 and the fixing ring 303. The outer wall of the dryer cylinder 104 is provided with a first connecting hole 305 and a second connecting hole 309, and the outer wall of the fixing ring 303 is provided with a third connecting hole 304 and a fourth connecting hole 308. The outer side of the fixing ring 303 is provided with a first connecting hole 305 and a second connecting hole 309. Arc strip 307 and arc strip 311, both have through holes on their outer walls. Threaded posts 312 are movably disposed within the two sets of through holes. A first threaded ring 313 and a second threaded ring 314 are threadedly connected to the outer wall of the threaded post 312. A first locking post 306 and a second locking post 310 are fixed to the inner walls of the first arc strip 307 and the second arc strip 311 respectively. The first locking post 306 engages in the first connecting hole 305 and the third connecting hole 304; the second locking post 310 engages in the second connecting hole 309 and the fourth connecting hole 308. Rotate the first threaded ring 313 and the second threaded ring 314 to disengage them from the threaded post 312, and then remove the threaded post 312 from the two sets of through holes to release the fixation on the first arc strip 307 and the second arc strip 311. Then drive the first arc strip 307 and the second arc strip 311 to separate. When the first locking post 306 disengages from the first connecting hole 305 and the third connecting hole 304, and the second locking post 310 disengages from the second connecting hole 309 and the fourth connecting hole 308, the fixation on the fixing ring 303 can be released. Then, use the fixing ring 303 in conjunction with the connecting rod 302 to drive the cleaning ring 301 to move inside the dryer drum 104, thereby achieving the purpose of cleaning the sludge on the inner wall of the dryer drum 104. This method has a high efficiency in cleaning the sludge on the inner wall of the dryer drum 104.

[0019] In summary, please refer to the following: Figures 1-4The base 101 is tilted at a certain angle, and then the filter plate 202 is placed inside the feed hopper 109. At this time, the limiting frame 201 will initially limit and fix the filter plate 202. Then, the rotating shaft 207 drives the threaded rod 206 to move in the threaded hole 204. When one end of the threaded rod 206 is engaged in the locking hole 205, the filter plate 202 can be finally fixed. The sludge is poured into the feed hopper 109 and enters the feed cylinder 108 through the feed hopper 109, and then enters the dryer cylinder 104 through the feed cylinder 108. When the sludge enters the feed cylinder 108 through the feed hopper 109, the sludge will be filtered by the filter plate 202. After the sludge enters the dryer cylinder 104, the motor 106 is started. The motor 106 will drive the dryer by using the drive gear 107 and the connecting gear. The cylinder 104 rotates to dewater and dry the sludge. When the equipment stops, the first threaded ring 313 and the second threaded ring 314 are rotated and disengaged from the threaded post 312. The threaded post 312 is then removed from the two sets of through holes, which releases the fixation on the first arc strip 307 and the second arc strip 311. The first arc strip 307 and the second arc strip 311 are then driven to separate. When the first locking post 306 disengages from the first connecting hole 305 and the third connecting hole 304, and the second locking post 310 disengages from the second connecting hole 309 and the fourth connecting hole 308, the fixation on the fixing ring 303 is released. The fixing ring 303, in conjunction with the connecting rod 302, drives the cleaning ring 301 to move inside the dryer cylinder 104, thereby achieving the purpose of cleaning the sludge on the inner wall of the dryer cylinder 104.

[0020] As can be seen from Embodiments 1 and 2, on the one hand, the filter plate 202 can filter impurities in the sludge, thereby preventing impurities in the sludge from entering the interior of the dryer cylinder 104, thus preventing the dryer cylinder 104 from being blocked or even damaged by impurities, ensuring the working efficiency of the dryer cylinder 104 and the dewatering and drying efficiency of the sludge; on the other hand, the fixed ring 303, in conjunction with the connecting rod 302, drives the cleaning ring 301 to move inside the dryer cylinder 104, thereby achieving the purpose of cleaning the sludge on the inner wall of the dryer cylinder 104.

[0021] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
