Description

Technical Field

[0001] This utility model relates to the field of dust removal technology for coal mills, specifically a clinker inclined zipper structure for cement processing. Background Technology

[0002] In the cement production process, the transportation of clinker is a crucial step. Clinker is a product of high-temperature calcination, possessing unique properties such as high temperature and a certain degree of hardness.

[0003] From the perspective of cement production technology, clinker needs to be efficiently transported to the next production stage, such as cement milling, after exiting the rotary kiln. Traditional conveying methods are difficult to meet the continuous, large-volume, and stable conveying requirements. The clinker inclined chain structure uses a chain to drive the hopper in a cyclical motion, achieving the carrying and conveying of clinker. This conveying method can adapt to a certain inclination angle, completing the vertical or inclined conveying of materials within a limited space.

[0004] However, existing clinker bucket conveyors for cement processing have many problems. In terms of conveying efficiency, due to limitations in their structural design and operating parameters, the amount of clinker conveyed per unit time is insufficient to meet the demands of the ever-increasing scale of cement production. Furthermore, during long-term clinker conveying, clinker dust easily accumulates in the buckets, chains, and conveying channels. This not only increases the weight of the equipment but also affects its normal operation, leading to frequent malfunctions. Therefore, regular cleaning of the equipment is required, which undoubtedly increases maintenance costs and downtime, reducing the overall efficiency of cement production. Utility Model Content

[0005] Based on the above-mentioned problems in the existing technology, the purpose of this utility model embodiment is to provide a clinker inclined zipper structure for cement processing, which facilitates stable and continuous transportation of cement clinker.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a clinker inclined zipper structure for cement processing, comprising several chain links and several hoppers; The chain link includes two pairs of chain plates and a crossbeam. The two pairs of chain plates are located at the two ends of the crossbeam respectively. One of the chain plates in each pair is fixedly connected to one end of the crossbeam, and the other chain plate is symmetrically arranged with the first chain plate. Two pins are provided between the ends of the two chain plates. The crossbeam has multiple through holes, and bolts are provided in the through holes. The two chain links are connected by the rotatable engagement of the chain plates and the pins. The bottom of the hopper has multiple through holes, and the hopper is mounted on the crossbeam and the hopper and the crossbeam are fixed together by bolts.

[0007] Furthermore, an outward flap is provided at the top of one of the side walls of the hopper.

[0008] Furthermore, it includes a pair of drive rollers, each of which has an inner support plate at both ends. The inner support plate has multiple teeth at its edge, and the multiple teeth are arranged along the circumference of the inner support plate. Several chain links are connected by the chain plate and the pin in a rotatable engagement to form a chain that is connected end to end. The two drive rollers are both sleeved inside the two ends of the chain. The chain links are connected to the inner support plate by the frame structure formed by the chain plate and the pin being fitted onto the tooth.

[0009] Furthermore, it includes two side support devices, each of which includes a side support rail one, a side support rail two, and a plurality of support columns. The slots of the side support rail one and the side support rail two are in the same direction and both face the side. The plurality of support columns are fixedly disposed between the side support rail one and the side support rail two. The two side support devices are located on the outside of the two chains respectively, and the slots of the first side support track and the second side support track cover the side of the chain.

[0010] Furthermore, the side support device includes multiple extension columns and a base. The multiple extension columns are disposed on the end face of the side support track two away from the support column, and the base is fixedly disposed on the end of the extension column away from the side support track two.

[0011] Compared with the prior art, the beneficial effects achieved by this utility model are: 1. Two drive rollers are driven to rotate in the same direction by external torque. They drive several hoppers to circulate through a chain. When the entire device is tilted at the clinker outlet, the clinker falls into the hopper and moves to the next device until the hopper flips, at which point the clinker is poured out. During this process, an outward flap is provided at the top of one of the side walls of the hopper, so that the gap between two adjacent hoppers is blocked before they flip, preventing clinker from falling between two adjacent hoppers, which would make it difficult to clean or even fall into the chain and affect the operation. The flipping of the hopper automatically pours out the clinker and moves in the opposite direction with the chain. This process helps to remove residual slag in the hopper and reduces the frequency of regular cleaning of the hopper. 2. By removing the bolts, the corresponding hopper can be removed for replacement and maintenance. 3. The side support device uses side support rail one and side support rail two to support the chain, preventing the chain from becoming too long and slack in the middle, which would affect the transmission efficiency. At the same time, it also provides external protection for the chain, preventing clinker residue from falling into the chain from outside the hopper and causing chain damage.

[0015] Please see Figure 1-5 The present invention provides a technical solution: a clinker inclined chain structure for cement processing, comprising a pair of drive rollers 1, several chain links 2, several hoppers 3, and two side support devices 4.

[0016] Both ends of the drive roller 1 are provided with inner support disks 11, and multiple locking teeth 12 are provided at the edge of the inner support disks 11. The multiple locking teeth 12 are arranged along the circumference of the inner support disks 11.

[0017] Link 2 includes two pairs of chain plates 21 and a crossbeam 22.

[0018] Two pairs of chain plates 21 are located at the two ends of the crossbeam 22 respectively. One of the chain plates 21 in each pair is fixedly connected to one end of the crossbeam 22, and the other chain plate 21 is symmetrically arranged with the first chain plate 21. Two pins 211 are provided between the ends of the two chain plates 21. Multiple through holes are provided on the crossbeam 22, and bolts 221 are provided in the through holes. The two chain links 2 are connected by the chain plate 21 and the pins 211 rotating together.

[0019] Several chain links 2 are connected by a rotating engagement of chain plate 21 and pin 211 to form a chain with the ends connected. Two drive rollers 1 are fitted inside the chain at both ends. The chain links 2 are engaged with the inner support plate 11 by a frame-shaped structure formed by chain plate 21 and pin 211, which is fitted onto the tooth 12.

[0020] The bottom of the hopper 3 has multiple through holes 30. The hopper 3 is mounted on the crossbeam 22 and the hopper 3 and the crossbeam 22 are fixed together with bolts 221. The top of one of the side walls of the hopper 3 is provided with an outward flap 31.

[0021] The side support device 4 includes a first side support rail 41, a second side support rail 42, and several support columns 43. The slots of the first side support rail 41 and the second side support rail 42 are in the same direction and both face the side. Several support columns 43 are fixedly installed between the first side support rail 41 and the second side support rail 42. The two side support devices 4 are located on the outside of the two chains respectively. The slots of the first side support rail 41 and the second side support rail 42 cover the side of the chain. The side support device 4 includes multiple extension columns 44 and a base 45. The multiple extension columns 44 are installed on the end face of the second side support rail 42 away from the support columns 43. The base 45 is fixedly installed on the end of the extension column 44 away from the second side support rail 42.

[0022] Two drive rollers 1 are driven by external torque to rotate in the same direction. They drive several hoppers 3 to circulate through a chain. When the entire device is tilted at the clinker outlet, the clinker falls into the hopper 3 and moves to the next device until the hopper 3 flips over, at which point the clinker is poured out. During this process, an external flap 31 is provided at the top of one of the side walls of the hopper 3, so that the gap between two adjacent hoppers 3 is blocked before they flip, preventing clinker from falling between two adjacent hoppers 3, which would make it difficult to clean or even fall into the chain and affect the operation. The flipping of the hopper 3 automatically pours out the clinker and moves in the opposite direction with the chain. This process is conducive to the removal of residual slag in the hopper 3, reducing the frequency of regular cleaning of the hopper 3.

[0023] In addition, by removing bolt 221, the corresponding hopper 3 can be removed and the specific hopper 3 can be replaced or repaired.

[0024] The side support device 4 uses side support rail 1 41 and side support rail 2 42 to support the chain, preventing the chain from becoming too long and slack in the middle, which would affect the transmission efficiency. At the same time, it also provides external protection for the chain, preventing clinker residue from falling into the chain from outside the hopper 3 and causing chain damage.
