Technical Field

[0001] The utility model relates to the technical field of dried sludge processing, in particular to a dried sludge crusher. Background Art

[0002] With the rapid development of industrialization and urbanization, sludge treatment has become an important issue of environmental protection. Sludge, as an inevitable product of sewage treatment, contains a large amount of water and organic matter. If it is not effectively treated, it will not only occupy a large amount of land resources, but also may cause secondary pollution to the environment. Sludge drying is to evaporate the water in the sludge through heating, ventilation and other means to convert it into dried sludge with a lower moisture content. Dried sludge not only greatly reduces its volume, but also facilitates subsequent transportation and disposal. However, the dried sludge often appears in block or granular form and needs to be further crushed for resource utilization. Most of the sludge crushing equipment on the market currently has unsatisfactory crushing effect, and its crushing structure is relatively simple, which is not convenient for fully crushing large and hard sludge blocks in the sludge, reducing the crushing efficiency. Therefore, it is necessary to design a drying sludge crusher. Utility Model Content

The crushing box 1 can be supported by the supporting legs 102. A feeding hopper 101 is fixedly installed on the top of the crushing box 1. The feeding hopper 101 and the crushing box 1 are connected to each other, so that the dried flower sludge to be crushed can be introduced into the crushing box 1 through the feeding hopper 101 for crushing operation. A driving assembly 4 is arranged inside the crushing box 1. The driving assembly 4 includes a second motor 401 and a rotating rod 402. The rotating rod 402 and the crushing box 1 are rotatably installed through a rotating shaft. A second motor 401 cooperating with the rotating rod 402 is fixedly installed on the bottom of the crushing box 1. The output end of the second motor 401 is fixedly connected to the rotating rod 402, which can drive the rotating rod 402 to rotate. A crushing assembly 5 is fixedly installed on the outer side of the rotating rod 402. The crushing assembly 5 includes crushing leaves 501, crushing teeth 502 and crushing thorns 503. The crushing leaves 501 are fixedly connected to the rotating rod 402, so that the crushing leaves 501 can be driven to rotate when the rotating rod 402 rotates. The crushing leaves 501 are designed in upper and lower layers. The crushing leaves 501 on the upper layer are inclined upward, and the crushing leaves 501 on the lower layer are inclined downward, so that a V-shaped angle can be formed between the crushing leaves 501. The front end of the crushing leaves 501 is fixed. The crushing blade 501 is connected with crushing teeth 502, which can make the crushing blade 501 rotate, and can double crush the sludge block through the crushing teeth 502 to reduce the occurrence of omissions. The top and bottom of the crushing blade 501 are fixedly installed with crushing spikes 503, and the crushing spikes 503 are in the shape of a hook. Through the hook shape of the crushing spikes 503, when colliding with the sludge block, the pressure can be concentrated on the tip of the crushing spikes 503, which can quickly crush large and hard sludge blocks with force, effectively improving the crushing effect.

[0022] A screening assembly 3 is rotatably installed inside the crushing box 1. The screening assembly 3 includes a rotating ring 301, a screening plate 302, a screening hole 303 and a rack 305. The rotating ring 301 is rotatably connected to the crushing box 1. A track groove 105 that cooperates with the rotating ring 301 is provided on the inner wall of the crushing box 1. The rotating ring 301 can be limited by the track groove 105 so that the rotating ring 301 can rotate along the track groove 105 without falling off. A rack 305 is fixedly installed on the outer side of the rotating ring 301. A first motor 2 is fixedly installed on one side of the crushing box 1. The output end of the first motor 2 is fixedly connected to a driving gear 201.

The driving gear 201 is driven to rotate by the first motor 2, and the rotating ring 301 can be driven to rotate synchronously through the rack 305, which can conveniently provide power for the rotating ring 301. A screening plate 302 is fixedly installed on the inner side of the rotating ring 301, and a screening hole 303 is provided on the surface of the screening plate 302. The rotation of the rotating ring 301 drives the screening plate 302 to rotate, and the crushed sludge particles can be screened through the screening hole 303.

[0023] The screening assembly 3 also includes a first crushing knife 304, a fixing rod 306 and a second crushing knife 307. The first crushing knife 304 is fixedly connected to the adjacent position of the screening hole 303. The fixing rod 306 is fixedly connected to the crushing box 1 by bolts. The second crushing knife 307 is fixedly installed at the bottom of the fixing rod 306. The second crushing knife 307 is staggered with the first crushing knife 304 and can rotate through the screening plate 302 to drive the first crushing knife 304 to rotate, so that a shearing effect can be formed between the first crushing knife 304 and the second crushing knife 307, and the sludge blocks on the screening plate 302 can be crushed again until the sludge particles can meet the size of the screening holes 303, so that the sludge particles can be exported through the screening holes 303, which effectively improves the screening effect. The discharge hopper 103 is fixedly connected to the bottom of the crushing box 1, and the discharge hopper 103 and the crushing box 1 are connected to each other, so that the screened sludge particles can be introduced into the discharge hopper 103 for export, which is convenient for collection.

[0024] The working principle of the dried sludge pulverizer based on the embodiment is as follows: by placing the device at a suitable position for use, the dried sludge blocks to be pulverized are introduced into the pulverizing box 1 through the feed hopper 101, and the second motor 401 is started to drive the rotating rod 402 to rotate, which can synchronously drive the pulverizing blades 501 to rotate, and the dried sludge blocks can be pulverized by the pulverizing teeth 502, and large and harder sludge blocks can be quickly crushed by the curved hook-shaped crushing thorns 503, which can effectively avoid the situation where the harder sludge blocks are not completely pulverized, and the pulverized sludge blocks fall onto the screening plate 302, and the first motor 2 is started to drive the driving gear 201 to rotate, and the pulverizing teeth 502 are used to pulverize the dried sludge blocks. The overdrive gear 201 is meshed with the rack 305, which can drive the rotating ring 301 to rotate in the track groove 105. The rotation of the rotating ring 301 can drive the screening plate 302 to rotate, which can facilitate the screening of the sludge blocks. The rotation of the screening plate 302 can drive the first crushing knife 304 to rotate. The staggered action of the first crushing knife 304 and the second crushing knife 307 can form a shearing effect, and the sludge blocks can be crushed again so that the sludge blocks can meet the size of the screening holes 303. The sludge particles can be quickly screened and introduced into the discharge hopper 103 for output.
