Abstract
Description
Technical Field
[0001] This utility model relates to the field of chromium carbide pretreatment technology, and in particular to a pulverizing device for chromium carbide pretreatment. Background Technology
[0002] In the chromium carbide pretreatment process, the crushing device plays a crucial role in breaking down and grinding lumpy or coarse chromium carbide into fine powder. However, in the actual crushing process, due to the squeezing action of the crusher, the chromium carbide material will break into particles of uneven size. Among them, the larger particles are difficult to burn completely in subsequent stages due to the limited reaction area, while the fine powder that is too small is prone to agglomeration during the sintering stage, forming clumps, which directly interferes with the uniformity and stability of subsequent processing.
[0003] The core defect of existing crushing equipment lies in the lack of an efficient sorting mechanism, which cannot quickly and accurately separate crushed particles into the required fineness. This results in large particles and fine powder that do not meet the requirements being mixed in with qualified materials. This not only requires additional secondary processing, increasing production time and costs, but may also affect the overall quality of materials due to untimely sorting, thus restricting the efficiency of subsequent processing and the performance of finished products.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.
[0026] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0027] like Figures 1 to 4 As shown, this application provides a crushing device for chromium carbide pretreatment, including a sorting box 1, a jaw crusher 2 disposed at the top of the sorting box 1, and a transmission belt 3 disposed on the front of the jaw crusher 2.
[0028] The coarse crushing and sorting device includes two sets of drive shafts 9, two sets of drive belts 8 connected to the outer walls of the two sets of drive shafts 9, a connecting horizontal plate 13 fixedly connected to the outer walls of the two sets of drive belts 8, a pusher plate 5 fixedly connected to the top of the connecting horizontal plate 13, an inclined plate 6 arranged on the opposite side of the pusher plate 5, and a side partition 7 arranged on the side of the inclined plate 6, which is used to separate large particles of crushed material and perform secondary crushing.
[0029] After adopting the above technical solution, the chromium carbide particles crushed by the jaw crusher 2 will fall naturally into the sorting box 1 due to their own gravity. At this time, the larger particles in the particle group will be successfully intercepted by multiple sets of inclined baffles 6 and will stay steadily on the upper surface of the baffles 6. The external motor will then start, driving the transmission shaft 9 to rotate smoothly inside the sorting box 1, thereby causing the two sets of transmission belts 8 to maintain a uniform speed. Multiple sets of connecting horizontal plates 13 will rotate synchronously under the drive of the transmission belts 8. The pusher plate 5, which is fixedly connected to the top of the connecting horizontal plate 13, slides along the inner side of the two sets of inclined baffles 6, continuously pushing the large particles intercepted at the top of the inclined baffles 6 towards the side partition 7, until they are pushed to the other side of the side partition 7, realizing the centralized collection of large particles, which greatly facilitates the subsequent secondary crushing of these particles by the staff.
[0030] In an optional embodiment, the medium and fine crushing separation mechanism, located at the bottom of the coarse crushing and sorting device, includes multiple sets of load-bearing rods 19, a screen plate 14 attached to the top of the load-bearing rods 19, three sets of pusher plates 20 disposed inside the screen plate 14, a transmission belt 21 fixedly connected to the opposite sides of the three sets of pusher plates 20, and two sets of transmission shafts 22 connected to the inner wall of the transmission belt 21, for transmitting medium crushed particles to the upper end of the transmission belt 3.
[0031] At the same time, the transmission shaft 22 is driven by an external power source to rotate inside the sorting box 1, and the transmission belt 21 will rotate synchronously on its surface. The three sets of pusher plates 20 fixedly connected to the surface of the transmission belt 21 will also rotate synchronously, thereby pushing the medium particles remaining at the top of the sieve plate 14 to the front smoothly until the medium particles are accurately pushed to the top of the transmission belt 3, and then the transmission belt 3 will transfer them to the next processing step.
[0032] In an optional embodiment, the sorting box 1 has two sets of discharge ports on its side. Each set of discharge ports has a collection trough 4 fixedly connected inside. The inner wall of each collection trough 4 is fixedly connected to a ramp 18. One set of ramp 18 has its side fixedly connected to the bottom of the side partition 7, and the inner wall of the other set of ramp 18 is fixedly connected to the bottom of the inner wall of the sorting box 1. Two sets of collection troughs 4 are specifically provided on both sides of the sorting box 1 to collect coarse and fine particles respectively, effectively separating and storing particles unsuitable for direct processing, greatly facilitating subsequent targeted processing of the coarse and fine particles by workers.
[0033] In one optional embodiment, the two sides of the side partition 7 are fixedly connected to the inner wall of the sorting box 1. The side partition 7 has several sets of slots inside, which are movably fitted with the outer wall of the pusher plate 5. When the pusher plate 5 rotates with the transmission belt 8, its movement trajectory follows a precise pattern: when the pusher plate 5 rotates to the side close to the side partition 7, it will push the coarse particles off the top of the inclined plate 6; after the pusher plate 5 continues to rotate, it will return to the bottom position of the inclined plate 6 through the slots inside the side partition 7, preparing for the next round of pushing.
[0034] In one optional embodiment, the inclined plate 6 is arranged at an angle with one end higher than the other, wherein the higher end of the inclined plate 6 is at the same height as the top of the side partition 7. When the pusher plate 5 pushes the coarse particles to the end of the inclined plate 6, the height of the accumulated coarse particles will be higher than the side partition, which facilitates the collection of the fallen coarse particles.
[0035] In one optional embodiment, the inner wall of the sorting box 1 is movably sleeved with the screen plate 14. An eccentric circle 11 is fitted to the outer wall of the screen plate 14, and a vibrating shaft 12 is fixedly sleeved to the inner wall of the eccentric circle 11. The connection point between the vibrating shaft 12 and the eccentric circle 11 is eccentrically connected. A push plate 17 is fitted to the other side of the screen plate 14. A limiting sleeve 15 is fixedly connected to the outer wall of the push plate 17. A spring 16 is movably sleeved to the inner wall of the limiting sleeve 15, and the outer wall of the spring 16 is movably sleeved with the sorting box 1. The eccentric circle 11 is fitted to the side of the screen plate 14. The side of the screen plate 14 and the eccentric circle 11 are tightly fitted. When an external power source drives the vibrating shaft 12 to rotate, the eccentric circle 11 will rotate eccentrically accordingly. When the protruding end of the eccentric circle 11 rotates to a position farther from the screen plate 14, the screen plate 14, under the action of the elastic potential energy of the spring 16, is pushed to a position parallel to the concave end of the eccentric circle 11. When the protruding end of the eccentric circle 11 rotates to a position adjacent to the screen plate 14, the screen plate 14 is pushed to the inside of the sorting box 1. This cycle repeats, causing the screen plate 14 to swing left and right continuously at the top of the load-bearing rod 19, thereby causing the fine particles to fall to the lower end of the screen plate 14 during the shaking process, achieving effective separation of fine particles and effectively ensuring the stability of the particle quality at the upper end of the screen plate 14.
[0036] In an optional embodiment, an extension block 10 is movably sleeved at the top of the vibrating shaft 12, and the side of the extension block 10 is fixedly connected to the sorting box 1. By adding the extension block 10, the eccentric circle 11 is cleverly positioned outside the sorting box 1, which can reduce the interference and influence of broken particles on the rotation of the eccentric circle 11.
[0037] In an optional embodiment, the sieve plate 14 has several sets of sieve holes inside, the size of which is smaller than the distance between the two sets of inclined plates 6.
[0038] It should be noted that the screen hole size inside the screen plate 14 is designed to be larger than the spacing of the inclined plate 6, so as to ensure efficient separation of coarse and medium crushed particles.
