Description

TECHNICAL FIELD

A large amount of dust is generated during the production process of cement.

[0053] The bottom of the platform plate 1 is provided with a frame 5, and the frame 5 is provided with a dust collecting mechanism 6, which comprises a rubber strip 61 fixedly connected to the top of the frame 5, and the top of the rubber strip 61 is fixedly connected to the bottom of the platform plate 1. The frame 5 is fixedly connected with a partition plate 62, the top of the partition plate 62 is fixedly connected with a mesh plate 63, and the frame 5 is fixedly connected with a second fan 64, which is electrically connected with the pressure sensor 42.

The bottom of the frame 5 is fixedly connected with a vibration motor 67, which drives the frame 5 to vibrate after working. The mesh plate 63 can filter and isolate the dust falling down.

[0054] A sealing door 68 is arranged on the front side wall of the frame 5, and the sealing door 68 is connected with the frame 5 through a hinge. An inclined plate 69 is integrally formed on the rear side wall of the inner cavity of the frame 5. An L-shaped plate 691 is fixedly connected to the rear side wall of the frame 5. A threaded rod 692 is rotatably connected to the inner side of the L-shaped plate 691. One end of the threaded rod 692 is rotatably connected to the frame 5.

The threaded rod 692 penetrates through one side wall of the pushing plate 694 and is connected with the pushing plate 694 through threads. The threaded rod 692 drives the pushing plate 694 to move horizontally after rotating. The pushing plate 694 can push the dust collected in the frame 5 out of the opening position of the sealing door 68.

[0055] A through groove 7 is formed in the platform plate 1 and communicates with the frame 5 and the shell 2. An air inlet is formed in the top of the shell 2. A filter cover plate 8 is fixedly connected to the top of the shell 2 and is arranged on the top of the air inlet. A vertical plate is fixedly connected to the bottom of the platform plate 1. A universal wheel 9 is fixedly connected to the bottom of the vertical plate. External air enters the inner cavity of the shell 2 through the air inlet. The filter cover plate 8 can filter the dust in the air.

[0056] In actual operation, when the device is used, first, the device is powered on, and then the device is pushed to the cement production area. When the first fan 38 works, the airflow enters through the air inlet frame 36 and is discharged through the air outlet frame 37. During this period, when the air passes through the filter bag 34, the dust contained in the air is filtered and retained in the filter bag 34, thereby achieving the dust removal purpose.

[0057] When the air is discharged through the exhaust frame 37, the air passing through the movable plate 43 will cause the movable plate 43 to move, and the movable plate 43 will exert pressure on the pressure sensor 42 after moving. As the dust accumulated in the filter bag 34 continues to increase, the air passing property of the filter bag 34 will become worse, so the pressure exerted by the air discharged by the exhaust frame 37 on the movable plate 43 will gradually decrease. When the pressure sensor 42 detects that the pressure exerted by the movable plate 43 on it is too small, it represents that the dust accumulated in the filter bag 34 has reached a large value and needs to be replaced. At this time, the first fan 38 stops working, and then the two first electric push rods 398 push the two rectangular plates 397 away from the housing 2, respectively. After the air inlet frame 36 and the exhaust frame 37 are away from the frame plate 33, the first motor 383 works and drives the second gear 384 to rotate, the second gear 384 drives the first gear 382 to rotate, the first gear 382 drives the first circular rod 32 to rotate one hundred and eighty degrees, and the filter bag 34 full of dust is exchanged with the unused dust collecting bag in position. Then repeat the above similar operation to control the air inlet frame 36 and the exhaust frame 37 to insert one end into the groove 396 of the frame plate 33, and the first fan 38 starts to continue the dust removal work.

[0058] After the above operation is completed, the fourth electric push rod 388 located at the position of the filter bag 34 full of dust works and pushes the moving plate 386, the moving plate 386 drives the connected rack 387 to move, the rack 387 drives the engaged third gear 385 to rotate, the third gear 385 drives the second circular rod 35 to rotate, and the second circular rod 35 drives the connected frame plate 33 to rotate ninety degrees. Then the frame plate 33 drives the filter bag 34 to turn ninety degrees, which causes the filter bag 34 full of dust to turn to open downward to facilitate cleaning of the internal dust.

[0059] After the filter bag 34 opens downward, the third electric push rod 381 works and pushes the limiting plate 395, the limiting plate 395 drives the auxiliary frame 391 to move to the upper side of the filter bag 34, and then the second electric push rod 399 pushes the lifting plate 392 downward. At this time, the electromagnetic block 394 is energized, and when the electromagnetic block 394 moves downward to the position of the metal block 39, the electromagnetic block 394 absorbs the metal block 39. The second electric push rod 399 is quickly extended and retracted. As can be seen from the above connection relationship, at this time, the metal block 39 drives the metal block 39 to move up and down quickly, thereby realizing the shaking effect of the filter bag 34, and shaking the dust in the filter bag 34 to achieve the cleaning purpose.

[0060] During the shaking process of the above filter bag 34, the second fan 64 works to generate suction force to suck the above shaken dust into the frame 5, and the dust is isolated by the mesh plate 63 during the suction to facilitate the accumulation of the sucked dust in the space on one side of the partition plate 62. At the same time, the vibration motor 67 starts to work, and the frame 5 as a whole starts to shake under the elastic force of the spring plate 66. During the shaking process of the frame 5, the dust on the mesh plate 63 can be uniformly accumulated downward during the shaking process, which can avoid the blockage of the mesh plate 63 and the uneven accumulation of the dust, so as to fully utilize the space in the frame 33.

[0061] Since the dust in the cement production process is mostly cement dust, based on the above operation, the collected cement dust can be effectively collected and concentrated for the user to carry out the operation of reusing, etc. When it is necessary to clean the dust in the frame 5, after opening the sealing door 68, the second motor 693 works and drives the threaded rod 692 to rotate, and the threaded rod 692 drives the pushing plate 694 to move in the frame 5, so as to uniformly push the dust out of the opening opened by the sealing door 68. The inclined plate 69 has the advantage that when the pushing plate 694 is pushed out and moved back at a time, the inclined plate 69 can scrape off the dust possibly attached to the top of the pushing plate 694, so as to push out the remaining dust in the next pushing plate 694 pushing activity, so as to ensure that the dust can be fully pushed out. In this way, the user can directly receive the pushed dust, and the corresponding operation process is simple and convenient, which is conducive to the treatment of the cement dust and other reusable substances in the dust.

[0062] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, any equivalent changes made on the basis of the structure, shape, principle of the present application should be covered within the protection scope of the present application.
