Description

Technical Field

[0001] This utility model relates to the field of pulverizer technology, and in particular to a pneumatic pulverizer. Background Technology

[0002] In the coal mining industry, coal seam gas content has always been one of the important indicators for assessing the risk of coal and gas outbursts. When testing the gas content in a designated area, a certain amount of coal sample needs to be taken and crushed by a pneumatic pulverizer. The gas generated after crushing is then transported to a gas content analyzer for testing.

[0003] According to the patent document with publication number CN221039030U, the patent document describes a compressed air filtration device that filters slag and water vapor in underground compressed air. The filtered underground compressed air is then used as the power source for a pneumatic motor, which drives the blades to rotate and crush the coal sample. The speed at which the coal sample enters the blades is controlled by a baffle. The baffle is supported by a locking point on the inner wall of the tank. The centrifugal force generated by the rotation of the blades throws the crushed coal sample into the tank. As more and more coal powder accumulates in the tank, it pushes the baffle upwards and gradually reaches the top of the coal sample, thus completing the crushing of the coal sample.

[0004] In order to ensure the accuracy of the test, the coal sample in the crusher needs to be poured out and cleaned after each batch of coal samples is crushed. At this time, the entire crusher needs to be lifted and tilted, which is inconvenient to use. In particular, when cleaning the gap between the bottom of the tank and the blades, it is difficult to clean and easy to be scratched by the blades. Utility Model Content

[0037] like Figures 1-14 As shown, a pneumatic pulverizer includes a drive mechanism 1, a pulverizing mechanism 2, and a disassembly mechanism 3.

[0038] In this embodiment: the crushing mechanism 2 includes a crushing cylinder 201, which is located on the upper side of the crushing mechanism 2. A top cover 202 is provided on the top of the crushing cylinder 201. A blade 204 is rotatably connected inside the crushing cylinder 201. A rotating ring is fixed on the outside of the blade 204. A rotating groove that cooperates with the rotating ring is opened on the inner side of the crushing cylinder 201. A drive shaft 205 is inserted into the bottom of the blade 204. A clamp 203 is fitted over the top of the crushing cylinder 201 and the top cover 202. An air outlet pipe is fixed on the top of the top cover 202. The clamp 203 tightly covers the top of the crushing cylinder 201. The rotation of the drive shaft 205 drives the blade 204 to rotate inside the crushing cylinder 201 to crush the coal sample. The rotating ring of the blade 204 rotates in the rotating groove of the crushing cylinder 201. When cleaning, the blade 204 is disengaged from the drive shaft 205 by pulling the crushing cylinder 201 upward.

[0039] In this embodiment: the disassembly mechanism 3 includes a base 301, which is located at the bottom of the crushing cylinder 201. A movable plate 302 is slidably connected inside the base 301. Two first sliding rods 303 are symmetrically arranged on both sides of the movable plate 302. A first spring 304 is sleeved on the outer side of each of the two first sliding rods 303. A second sliding rod 305 is fixed to the front side of the movable plate 302. A second spring 306 is sleeved on the outer side of the second sliding rod 305. The ends of the two first sliding rods 303 away from the movable plate 302 are inserted into the crushing cylinder 201. Slots that cooperate with the first sliding rods 303 are opened on both sides inside the crushing cylinder 201. The movable plate 302 is inverted trapezoidal. Two first square slots are opened inside the base 301 to respectively limit the positions of the two first springs 304. The ends of the two first springs 304 near the movable plate 302 are respectively... The first spring 304 is fixedly connected to the first square groove. The ends of the two first springs 304 away from the moving plate 302 are respectively fixedly connected to the first slide rod 303. The base 301 has a second square groove for limiting the position of the second spring 306. The end of the second spring 306 near the moving plate 302 is fixedly connected to the second square groove. The end of the second spring 306 away from the moving plate 302 is fixedly connected to the second slide rod 305. By pressing the second slide rod 305 backward, the moving plate 302 is moved backward. The two first slide rods 303 are no longer squeezed by the moving plate 302. The two stretched first springs 304 retract, thereby driving the corresponding two first slide rods 303 to move towards the moving plate 302. The two first slide rods 303 disengage from the slots on both sides of the crushing cylinder 201, releasing the lock on the crushing cylinder 201.

[0040] In this embodiment: the drive mechanism 1 includes a support frame 101, a first connecting sleeve 102 is provided on the top of the support frame 101, a second connecting sleeve 103 is bolted to the bottom of the first connecting sleeve 102, a pneumatic motor 104 is fixedly installed at the bottom of the second connecting sleeve 103, a pneumatic dual unit 105 is fixed on one side of the support frame 101, support rods are fixed between both sides of the second connecting sleeve 103 and the support frame 101, an air supply pipe 106 is fixedly connected between the pneumatic dual unit 105 and the air inlet end of the pneumatic motor 104, a silencer 107 is fixed to the air outlet end of the pneumatic motor 104, and the pneumatic motor 104... A universal joint coupling 108 is fixedly installed at the output end. The drive shaft 205 is fixedly connected to the top of the universal joint coupling 108. The base 301 is fixed to the top of the first connecting sleeve 102. The compressed air is filtered by the pneumatic double unit 105. The filtered compressed air enters from the air inlet end of the pneumatic motor 104 through the air supply pipe 106, thereby providing power to the pneumatic motor 104 and then being discharged from the air outlet end of the pneumatic motor 104. The discharged compressed air is silenced by the silencer 107. The pneumatic motor 104 drives the pneumatic double unit 105 to drive the drive shaft 205 to rotate.

[0041] Working principle: The coal sample to be crushed is placed into the crushing cylinder 201. The clamp 203 tightly covers the top cover 202 on the top of the crushing cylinder 201. The air outlet pipe of the top cover 202 is connected to the gas detection equipment, and compressed air is introduced into the pneumatic dual unit 105. The pneumatic dual unit 105 filters the compressed air. The filtered compressed air enters from the air inlet of the pneumatic motor 104 through the air supply pipe 106, thereby providing power to the pneumatic motor 104 and then being discharged from the air outlet of the pneumatic motor 104. The discharged compressed air is silenced by the silencer 107. The pneumatic motor 104 drives the pneumatic dual unit 105 to drive the drive shaft 205 to rotate. The rotation of the drive shaft 205 drives the blade 204 to rotate in the crushing cylinder 201 to crush the coal sample. The rotating ring of the blade 204 rotates in the rotating groove of the crushing cylinder 201.

[0042] After the crushing test is completed, the crushing cylinder 201 needs to be cleaned. Press the second slide bar 305 to the rear to drive the moving plate 302 to the rear. The second spring 306 is compressed in the second square groove. During this process, the two first slide bars 303 are no longer squeezed by the moving plate 302. The two stretched first springs 304 retract, thereby driving the corresponding two first slide bars 303 to move closer to the moving plate 302. The two first slide bars 303 disengage from the slots on both sides of the crushing cylinder 201, releasing the lock on the crushing cylinder 201. Pull the crushing cylinder 201 upward to drive the blade 204 to disengage from the drive shaft 205.

[0043] After cleaning, place the crushing cylinder 201 on the base 301, insert the blade 204 into the drive shaft 205, stop pressing the second slide bar 305, and the compressed second spring 306 rebounds and extends, causing the second slide bar 305 and the moving plate 302 to move forward. The moving plate 302 squeezes the two first slide bars 303, causing the two first slide bars 303 to move away from the moving plate 302 and be inserted into the slots on both sides of the crushing cylinder 201, thus completing the installation of the crushing cylinder 201, and continue to crush and test the next batch of coal samples.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
