Technical Field
[0001] This utility model relates to the technical field of accessories for high-viscosity coal mine crushers, specifically a circulating self-cleaning device for high-viscosity coal mine crushers. Background Technology
[0002] High-viscosity coal mine crushers are mainly used to process coal minerals with high viscosity and moisture content (such as coal slime, coal gangue, etc.). The core equipment includes high-moisture and high-viscosity coal slime crushers and hammer crushers.
[0003] Currently, when high-viscosity coal mine crushers are in operation, the internal crushing rollers need to maintain a high-speed rotation state to avoid sticky coal materials from sticking together and clogging. However, during actual use, the crushed material will still cause clogging when it comes into contact with the inner wall of the crusher. Once the amount of clogging on the inner wall of the crusher increases, it will affect the actual rotation speed of the crushing rollers.
[0004] In view of this, a circulating self-cleaning device for high-viscosity coal mine crushers was designed to solve the above problems. Utility Model Content
[0005] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.
[0006] Therefore, the technical solution adopted by this utility model is as follows:
[0007] A circulating self-cleaning device for a high-viscosity coal mine crusher includes a crusher assembly, an internal pressurization assembly mounted on the crusher assembly, and two sets of cleaning assemblies installed inside the crusher assembly. The crusher assembly includes a housing, a hopper fixedly mounted on the housing, a pad fixedly mounted on the inner wall of the hopper, a baffle movably mounted in a groove in the inner wall of the hopper, a spring fixedly mounted at the bottom of the baffle, and the other end of the spring mounted on the inner wall of the groove. The inner wall of the housing has two slots. The cleaning assemblies include multiple bolts fixedly mounted on the inner wall of the slots, limit covers mounted on the bolts, multiple evenly distributed brushes inserted into the limit covers, and internal support rods fixedly mounted inside the brushes.
[0008] In a preferred embodiment, the present invention can be further configured as follows: the interior of the outer shell has a pipe hole, the bottom of the outer shell has a discharge groove, two main shafts are movably installed in the inner cavity of the outer shell, a crushing roller is fixedly installed on the outside of the main shaft, gears are installed on both main shafts, and a first pulley is installed on one of the main shafts.
[0009] In a preferred embodiment, the present invention can be further configured as follows: the internal pressurization assembly includes a shroud fixedly installed outside the outer casing, an impeller shaft is movably installed inside the shroud, a drive pulley is installed outside the impeller shaft, a drive belt is drively connected to the drive pulley and the first pulley, and an air pipe is fixedly installed at the bottom of the shroud, with the other end of the air pipe adapted to penetrate into the pipe hole.
[0010] In a preferred embodiment, the present invention can be further configured such that the interior of the limiting cover has multiple funnel-shaped slots.
[0011] In a preferred embodiment, the present invention can be further configured such that: the bottom end of the pad has an inclined surface, and the upper surface of the bottom of the baffle is adapted to fit against the inclined surface at the bottom end of the pad.
[0012] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:
[0013] 1. This utility model uses an internal pressurization component fixedly installed on the outer shell. When the external drive device drives the two main shafts and crushing rollers to rotate at high speed, the material fed into the hopper will be actively crushed by the two crushing rollers. Under the blowing of the high-pressure airflow, the crushed material will be gathered into tiny particles inside the outer shell and eventually discharged outward along the discharge chute.
[0014] 2. This utility model installs cleaning components in two slots. When the two crushing rollers rotate at high speed, the brushes guided by the limiting cover will pass through the gap between the hammers outside the crushing rollers, and can finally clean the material stuck to the hammers.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.
[0025] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.
[0026] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a circulating self-cleaning device for a high-viscosity coal mine crusher.
[0027] Example 1:
[0028] Combination Figures 1 to 5 As shown, the present invention provides a circulating self-cleaning device for a high-viscosity coal mine crusher, including a crusher assembly 100, an internal pressurization assembly 200 installed on the crusher assembly 100, and two sets of cleaning assemblies 300 installed inside the crusher assembly 100. The internal pressurization assembly 200 is used to continuously blow air into the crusher assembly 100 to enhance the stability of the state of the fine particles after crushing, and the cleaning assemblies 300 are used to continuously clean the crushing components inside the crusher assembly 100.
[0029] The crusher assembly 100 includes a housing 110, a hopper 120 fixedly mounted on the housing 110, a pad 1201 fixedly mounted on the inner wall of the hopper 120, a baffle 140 movably mounted in a groove in the inner wall of the hopper 120, a spring 130 fixedly mounted on the bottom of the baffle 140, and the other end of the spring 130 mounted on the inner wall of the groove. The inner wall of the housing 110 has two slots 1101, the inside of the housing 110 has a pipe hole 1102, the bottom of the housing 110 has a discharge groove 1103, and two main shafts 150 are movably mounted in the inner cavity of the housing 110. A crushing roller 160 is fixedly mounted on the outside of the main shaft 150, and a gear 170 is mounted on both main shafts 150. A first pulley 180 is mounted on one of the main shafts 150.
[0030] The bottom end of the pad 1201 is provided with a slope, and the upper surface of the bottom of the baffle 140 is adapted to fit against the slope at the bottom end of the pad 1201.
[0031] The cleaning component 300 includes a plurality of bolts 310 fixedly installed on the inner wall of the slot 1101, a limit cover 320 installed outside the plurality of bolts 310, a plurality of evenly distributed brushes 330 inserted inside the limit cover 320, an inner support rod 340 fixedly installed inside the brushes 330, and a plurality of funnel-shaped slots opened inside the limit cover 320.
[0032] In use, an external drive device is used to drive one of the main shafts 150, and the two gears 170 fixed on the two main shafts 150 will mesh and drive each other, so that the two crushing rollers 160 will maintain the same speed and rotate in opposite directions.
[0033] Next, the highly viscous coal is introduced into the hopper 120. After passing the inclined surface at the top of the baffle 140, the coal will be quickly transferred to the inner cavity of the outer shell 110. Finally, it will be actively crushed by two crushing rollers 160. The resulting tiny particles will be projected into the inner cavity of the outer shell 110. The transmission belt 240 driven by the first pulley 180 will drive the transmission pulley 230 and the impeller shaft 220 to rotate at high speed. Finally, the fan shroud 210 will continuously send air into the inner cavity of the outer shell 110. Under the action of the high-pressure airflow, the tiny particles will be quickly solidified, thus ensuring the stability of the properties of the solidified tiny particles.
[0034] Example 2:
[0035] Combination Figure 2 and Figure 4As shown, in the above embodiment, the internal pressurization assembly 200 includes a fan shroud 210 fixedly installed outside the housing 110. An impeller shaft 220 is movably installed inside the fan shroud 210. A drive pulley 230 is installed outside the impeller shaft 220. A drive belt 240 is drively connected to the drive pulley 230 and the first pulley 180. An air pipe 2101 is fixedly installed at the bottom of the fan shroud 210, and the other end of the air pipe 2101 is adapted to pass through the pipe hole 1102.
[0036] Preferably, the hood 210 is fixed to the outside of the housing 110 by welding, and the outer wall of the hood 210 is provided with an air inlet. As the impeller shaft 220 rotates forward, outside air will be actively drawn in through the air inlet and flow into the inner cavity of the housing 110 along the air pipe 2101. The airflow blowing horizontally along the inner cavity of the housing 110 will enhance the rapid discharge of the crushed coal and avoid the problem of material blockage in the inner cavity of the housing 110.
[0037] The working principle and usage process of this utility model are as follows: When in use, an external motor is used to drive one of the main shafts 150 to rotate. The main shaft 150, in conjunction with the crushing roller 160, will drive the gear 170 to rotate. Since the two gears 170 are meshed, the two crushing rollers 160 will maintain the same speed and rotate in opposite directions.
[0038] During the high-speed rotation of the two crushing rollers 160, the material introduced along the hopper 120 is actively crushed. When high-viscosity coal adheres to the crushing end of the crushing roller 160, the brushes 330, which are evenly distributed between multiple crushing ends, clean the coal residue on the outer wall of the crushing end. During the coal crushing process, the transmission belt 240 driven by the first pulley 180 drives the transmission pulley 230 and the impeller shaft 220 to rotate. The impeller shaft 220 draws in outside air and transfers it to the inner cavity of the outer shell 110. With the cooperation of high-speed airflow, the crushed coal can remain in small and independent pieces.
[0039] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
