Description

TECHNICAL FIELD

[0001] The utility model relates to filter pressing coal slime production technical field especially relates to a filter pressing coal slime crushing and stirring device. BACKGROUND

[0002] Roller crusher is a commonly used solid material crushing equipment, widely used in ore, coal, chemical raw materials and other fields. It mainly through two parallel installation roller cylinder opposite rotation, utilize the pressure between roller cylinder and crush the material into the particle size of the particle. In the treatment of coal slime, especially in the crushing process of filter pressing coal slime, due to its structure and working principle, roller crusher can usually realize efficient crushing and better particle size control. However, in practical application, roller crusher still faces several technical challenges when crushing filter pressing coal slime.

[0003] Firstly, filter pressing coal slime as a kind of material with high water content, its physical properties are more complex. When filter pressing coal slime enters roller crusher for crushing, due to the high water content in the material and the certain viscosity between particles, the crushing process is prone to the phenomenon that the material is not fully crushed. This phenomenon mainly reflects in the one-time crushing process, due to the limited contact area between crushing teeth and material, part of the coal slime lumps may not be fully crushed, thus producing larger particles. These oversized particles not only affect the product quality, but also may cause the processing efficiency to decrease or the equipment wear to increase in the subsequent process.

[0004] Secondly, due to the certain viscosity of filter pressing coal slime, especially when the water content is high or the temperature changes greatly, coal slime particles are easy to stick to the surface of crushing teeth or roller cylinder. This sticking phenomenon will lead to the decrease of working efficiency of crushing teeth, the deterioration of crushing effect, and even may cause the blockage or shutdown of the crusher for maintenance. The sticking coal slime not only affects the service life of the crushing teeth, but also may cause the crusher to need frequent cleaning and maintenance, increasing the production cost and the unplanned downtime of the equipment.

[0005] In summary, the existing roller crusher has the problems of oversized particles after one-time crushing and coal slime sticking to the crushing teeth when processing filter pressing coal slime, which seriously affects the use efficiency of the equipment and the quality of the final product. Therefore, an improved technical solution is needed to solve these problems in the prior art and improve the adaptability and working efficiency of the roller crusher in the processing of filter pressing coal slime.

[0006] Therefore, we propose a filter pressing coal slime crushing and stirring device. UTILITY MODEL CONTENT

Inside the outer shell 1, a crushing chamber 3 is horizontally positioned. The crushing chamber 3 is a hollow cylindrical shell with an open side curved surface forming a feed inlet 4. The bottom of the crushing chamber 3 is a filter screen to filter out the coal slime that meets the requirements. The crushing chamber 3 is equipped with a crushing assembly, which is a roller crushing assembly. When crushing and pressing coal slime, the rollers tend to stick to the tooth surface and produce a compaction effect rather than a crushing effect. Therefore, a turntable 7 is movably installed on one side of the crushing chamber 3. The turntable 7 is a circular plate. The edge of the disc 7 is provided with a central deflector plate 8 and multiple side deflector plates 9. The central deflector plate 8 is located at the bottom of the disc 7, opposite the feed inlet 4. Multiple sets of side deflector plates 9 are evenly and symmetrically arranged on both sides of the central deflector plate 8. The central deflector plate 8 and the side deflector plates 9 are in close contact with the crushing chamber 3. A deflector plate motor 11 is fixedly installed on the outside of the outer shell 1. The deflector plate motor 11 can drive the disc 7 to rotate back and forth. When the disc 7 rotates, it drives the central deflector plate 8 and the side deflector plates 9 to rotate in the crushing chamber 3, turning the coal slime that is still relatively large after being crushed by the crushing components to the upper part for re-crushing.

[0028] Furthermore, the side deflector plate 9 has multiple sets of avoidance teeth 10, which intersect with the adjacent crushing components to scrape off the coal slime adhering to the tooth surface of the crushing components.

[0032] Further, the crushing assembly comprises a crushing motor 12 fixedly installed on the side of the shell 1, an output end of the crushing motor 12 is fixedly installed with a crushing shaft 5, a part of the crushing shaft 5 extends to the inside of the crushing cavity 3, the side wall surface of the crushing shaft 5 is uniformly provided with crushing teeth 6, the side wall surface of the shell 1 is further movably installed with another group of crushing shafts 5, one end of the other group of crushing shafts 5 located outside the shell 1 is fixedly installed with a driven gear 14, a driving gear 13 is meshingly connected with the driven gear 14, the crushing teeth 6 on the two groups of crushing shafts 5 are staggered, when the crushing motor 12 is started, the driving gear 13 drives the driven gear 14 to rotate, so that the two groups of crushing shafts 5 rotate in opposite directions to crush.

[0033] Further, the shell 1 is movably installed with a stirring shaft 16 at a position below the crushing cavity 3, the side wall surface of the stirring shaft 16 is fixedly installed with stirring blades 17, the output end of the push plate motor 11 is fixedly installed with a belt 15 and the stirring shaft 16, the belt 15 drives the stirring shaft 16 to rotate, so that the coal slime after crushing is stirred to prevent static deposition, and can reciprocatingly rotate like the rotating disc 7 to strengthen the stirring effect.

[0034] The working principle of the utility model is as follows: starting the push plate motor 11 and the crushing motor 12, the coal slime is poured from the hopper 2, the coal slime is crushed by the crushing shaft 5 and the crushing teeth 6 through the feeding port 4, the coal slime meeting the requirements is filtered out through the filter screen below the crushing cavity 3, the coal slime not meeting the requirements is stored in the crushing cavity 3, at this time, the push plate motor 11 drives the rotating disc 7, the middle push plate 8 and the side push plate 9 to reciprocatingly rotate, the middle push plate 8 and the side push plate 9 push the stored coal slime to overturn along the arc surface of the crushing cavity 3, fall above the crushing shaft 5, re-crush, and the avoiding teeth 10 arranged on the side wall surface of the side push plate 9 and the crushing teeth 6 are staggered, so that the coal slime adhered on the crushing teeth 6 is scraped and cleaned.
