Description

Technical Field

[0001] The invention relates to the field of vibration coal preparation, and in particular to a coal preparation device with a vibration function. Background Art

[0002] Coal vibrating screening machines are widely used in industries that need to process large amounts of coal, such as thermal power plants and steel mills. In thermal power plants, the equipment can effectively remove non-combustible materials such as stones and metal fragments from coal piles to ensure the stability and safety of the subsequent combustion process. Coal vibrating screening machines have the function of efficient screening, which can effectively reduce labor intensity and improve coal utilization, and play an important role in the coal processing industry.

[0003] In the prior art, the screens of coal vibrating screening machines are mostly fixed in the device by the cooperation of screws and bolts. During the vibration process, the screws may become loose, thereby causing the screen to become loose. Once the screen becomes loose, it will not only affect the screening effect, but may also cause equipment failure or even safety accidents. Moreover, when replacing the screen, a large number of screws need to be removed before the screen is removed. The operation steps are relatively cumbersome. At the same time, cumbersome operations are also required when installing a new screen.

[0027] like Figure 3 As shown, a fixed cover 203 is fixedly connected to the outer side of the shell 1 at a position relative to the rotating cam 204, fixed blocks 102 are fixedly connected to both sides of the fixed cover 203, and the fixed blocks 102 are fixedly connected to the outer side of the shell 1, and a vibration plate 103 is fixedly connected to the lower end of the fixed block 102, and the vibration plate 103 is fixedly connected to the outer side of the shell 1, and two supporting springs 503 are symmetrically fixedly connected to the lower side of the vibration plate 103, and the lower end of the supporting spring 503 is fixedly connected to a vibration supporting frame 502, and the lower end of the vibration supporting frame 502 is fixedly connected to the bottom plate 504.

[0028] like Fig. 9 As shown, two protective sleeves 106 are symmetrically fixedly connected to the inner side of the shell 1, a rotating connecting rod 202 passes through the shell 1 and the protective sleeve 106 and the outer side located on the left side of the shell 1 is also fixedly connected with a rotating cam 204, and the end of the rotating connecting rod 202 located on the outside of the left side of the shell 1 is rotatably connected to a support block 206, and the lower side of the support block 206 is fixedly connected to a fixed support frame 501 located on the left side of the shell 1.

[0029] Working principle: when screening is required, the coal is transported to the inside of the shell 1 along the feed port 107 and the motor 201 on the right side of the shell 1 is started. At this time, the output end of the motor 201 drives the rotating connecting rod 202 to rotate, and drives the rotating cam 204 to rotate, and the rotating cam 204 squeezes the matching plate 205 to drive the shell 1 to reciprocate. At this time, the shell 1 drives the vibration plate 103 on the side to reciprocate and realizes the vibration of the shell 1 under the action of the vibration plate 103, and drives the screening net 101 inside the shell 1 to vibrate to achieve vibration screening of the coal.

[0030] During the use of the coal preparation equipment, the screening net 101 can be replaced according to the actual needs to meet the coal screening requirements of different standards. When the screening net 101 needs to be removed and replaced, the push-pull handle 303 is pushed toward the inside of the side protective shell 302. At this time, the push-pull handle 303 drives the push slider 316 to move toward the inside of the side protective shell 302. At this time, the push slider 316 is pushed up and down by the push-pull rods 312 on both sides of the inclined surface. The movement of the push-pull rod 312 drives the connecting plate 311 to move away from the fixed plate 313. At this time, the connecting plate 311 drives the connecting rod 323 to move to the same square. The two connecting rods 323 drive the sliding columns 309 in the two fixed sleeves 307 to move upward and downward and squeeze the trigger spring 308. At this time, the sliding columns 309 drive the L-shaped rods 310 on both sides to slide out of the square through holes of the trigger shell 314 and move away from the trigger shell 314. The L-shaped rod 310 drives the sliding plate 305 to move in the same direction, and the sliding plate 305 drives the locking column 306 to move away from the screening net 101. At this time, the locking column 306 slides out from the circular through holes of the upper clamping plate 104, the lower clamping plate 105 and the screening net 101, and the second return spring 319 pushes the locking link 318 downward, so that the locking link 318 slides into the through hole opened on the upper side of the pushing slider 316, limiting the pushing slider 316, thereby releasing the restriction on the screening net 101.

[0031] At this time, the push-pull connecting rod 408 is pulled outward again, and the connecting rod 409 and the limiting column 410 are moved away from the locking column 405, thereby releasing the restriction on the locking column 405. At this time, the sliding handle 403 is pushed upward, and the sliding handle 403 drives the connecting block 413 to move upward, and drives the connecting plate 404 to move in the same direction. At this time, the connecting plate 404 and the locking column 405 move upward under the drive of the connecting plate 404, and the locking column 405 slides out from the through holes of the upper clamping plate 104, the lower clamping plate 105 and the screening net 101, thereby releasing the restriction of the locking column 405 on the screening net 101, and the connecting block 413 slides upward. The linkage block 413 slides along the side of the supporting slider 414. When the linkage block 413 slides to the top of the supporting slider 414 and the screening net 101 is completely pulled out of the upper clamping plate 104 and the lower clamping plate 105, the fourth reset spring 415 releases its elastic force to push the trigger block 407 to move toward the outside of the fixed shell 401, so that the supporting slider 414 moves to the bottom of the linkage block 413. The supporting slider 414 supports and limits the linkage block 413. When the sliding handle 403 moves to the corresponding position, the locking link 402 is pushed toward the sliding handle 403 to limit the sliding handle 403 to the corresponding position, thereby releasing the restriction on the screening net 101.

[0032] When the restriction is released, the screening net 101 is pulled out. At this time, under the action of the pushing spring 324 between the guide block 320 and the trigger shell 314, the trigger shell 314 is moved away from the main protective shell 301 to achieve the reset of the trigger shell 314. At the same time, under the action of the fourth reset spring 415, the trigger block 407 is pushed to move away from the fixed shell 401. At this time, the trigger block 407 drives the supporting slider 414 to move in the same direction to achieve the reset of the trigger block 407.

[0033] When the screening net 101 needs to be installed, the screening net 101 is first pushed into the housing 1 along the gap between the upper clamping plate 104 and the lower clamping plate 105, and the screening net 101 pushes the trigger block 407 to both sides of the housing 1. The trigger block 407 drives the support slider 414 to move into the fixed shell 401 and compresses the fourth return spring 415, so that the support slider 414 releases the support for the linkage block 413. When the screening net 101 completely enters the housing 1, the locking link 402 is moved away from the locking link 402. The sliding handle 403 is in the position. At this time, the third return spring 411 will pull the connecting plate 404 downward, and at the same time drive the locking column 405 to move downward. At this time, the locking column 405 moves downward along the through holes of the upper clamping plate 104, the lower clamping plate 105 and the screening net 101 and passes through the limiting hole of the screening net 101 and is inserted into the locking shell 406. At this time, the push-pull connecting rod 408 is pushed, and the connecting rod 409 and the limiting column 410 are inserted into the blind hole at the lower end of the locking column 405 to lock the screening net 101.

[0034] At the same time, the locking link 318 is pushed upward and the second return spring 319 is squeezed to release the restriction on the push slider 316. The push slider 316 will move away from the side protective shell 302 under the action of the first return spring 317, and the support for the push-pull rod 312 will be released. At this time, under the push of the screening net 101, the trigger shell 314 moves along the guide block 320 toward the inside of the main protective shell 301, and at the same time, the push spring 324 is squeezed. When the square through holes on the upper and lower sides of the trigger shell 314 are aligned with the sliding column When the positions of 309 correspond, the sliding column 309 moves toward the inside of the trigger shell 314 under the action of the trigger spring 308, and at the same time drives the L-shaped rods 310 on both sides to move along the square through holes of the limit blocks 315 toward the trigger shell 314, and the L-shaped rods 310 drive the sliding plate 305 and the locking column 306 to move in the same direction, and the locking column 306 is inserted into the through holes of the upper splint 104, the lower splint 105 and the screening net 101, thereby realizing the locking of the screening net 101 by the locking column 306.
