Description

Technical Field

[0001] The utility model relates to the technical field of ore sample preparation equipment, in particular to a dust removal device for a waste rock bin ore sample preparation system. Background Technique

[0002] After separation in the concentrator, the discarded tailings are generally transported to the waste rock bin through a waste discharge belt. According to the needs of production work, it is necessary to automatically take and prepare samples of the waste rock for detection and analysis to judge the quality of the waste rock. Among them, sample preparation is to transport the sample stone to a crushing device for crushing and reduction. A large amount of dust will be generated during the sample preparation process, and the dust will affect the sample quality and the sample preparation environment. Therefore, a dust removal device will be used in combination. At present, the dust removal device uses a fan to extract air and uses a dust removal filter element to remove dust. The coarse-grained dust falls under the action of gravity, and the fine-grained and low-density dust particles are adsorbed on the filter material surface of the filter element. However, the current dust removal device has the following defects:

[0003] As the dust removal device works continuously, the dust particles adsorbed on the filter material of the filter element increase continuously, resulting in an increase in the resistance of the overall device, which will affect the dust removal effect. Based on this, most dust removal devices are provided with a device for cleaning the filter element, and generally use the reverse blowing method for cleaning. However, when the dust removal device is working, reverse blowing cleaning cannot be carried out, and reverse blowing cleaning can only be carried out after the machine is stopped, which is not very practical.

Detailed Embodiment

[0022] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the utility model.

[0023] Embodiment 1:

[0024] Please refer to Figures 1-3 Figures 1-3 , the present utility model provides a technical solution: a dust removal device for a waste rock bin ore sample preparation system, including a cabinet 1 and a plurality of hinges 12. An inner cavity 11 is opened on one side inside the cabinet 1. A dust removal bin 2 is fixedly connected to the middle of the inner cavity 11. A cross plate 3 is fixedly connected to the position above the dust removal bin 2 in the inner cavity 11. A dust cleaning component 4 is arranged between the cross plate 3 and the dust removal bin 2 in the inner cavity 11. The top surface of the dust removal bin 2 is an open structure, and a plurality of dust removal filters 21 are fixedly connected inside the dust removal bin 2;

[0025] The dust cleaning component 4 includes a top plate 41 and an air storage tank 42. The top plate 41 is fixedly connected to the top surface of the dust removal bin 2. A blow head 49 is movably arranged on the top plate 41. The bottom end of the blow head 49 is fixedly connected and communicated with a blow hood 419. The blow hood 419 contacts the top surface of any one of the dust removal filters 21. The air storage tank 42 is fixedly connected to the bottom surface of the cross plate 3. A spray pipe 43 is fixedly connected and communicated with one side of the air storage tank 42. A hose 410 is fixedly connected and communicated between the spray pipe 43 and the blow head 49. A pulse solenoid valve 44 is fixedly connected and communicated with the top surface of the spray pipe 43. The dust cleaning component 4 uses the pulse reverse blowing method to blow and clean the dust removal filters 21 in reverse. A movable blow hood 419 is set to perform the pulse reverse blowing work. Dust removal work is carried out through the plurality of dust removal filters 21 provided. The blow hood 419 can move to any one of the dust removal filters 21 for spraying. In this way, when performing the pulse reverse blowing and cleaning work, the remaining dust removal filters 21 can continue to perform the dust removal work, realizing the effect of cleaning the ash without stopping the machine, which is more practical;

[0026] A centrifugal fan 31 is fixedly connected to the top surface of the cross plate 3. An air duct opening 32 is vertically opened on the cross plate 3.

On the top surface of the top sliding block 412, a second servo reduction motor 427 is fixedly connected. At the rotating shaft end of the second servo reduction motor 427, it is fixedly connected to the rotating shaft of the driving pulley 421. By driving the second synchronous belt 424 to move through the second servo reduction motor 427, the side sliding block 426 can be pulled to move, realizing the horizontal movement of the blowing hood 419 in another direction, so that the blowing hood 419 can be located on the top of any dust removal filter element 21.

[0034] Please refer to Figures 1-5, which is the third embodiment of the present utility model. This embodiment is based on the above two embodiments. When the present utility model is in use, the dust collection hood of the sample preparation device is connected to the flange air inlet 16. Under the action of the centrifugal fan 31, the dust-containing gas of the sample preparation device enters the dust removal chamber 2 from the flange air inlet 16. After being blocked by the dust removal filter element 21, most of the coarse particle dust directly falls into the conical bottom shell 22. Under the negative pressure generated by the centrifugal fan 31, the fine-grained and low-density dust particles, through the combined effects of Brownian diffusion and sieving, make the dust adsorb on the outer surface of the filter material of the dust removal filter element. The purified gas is discharged by the centrifugal fan 31 through the flange air outlet 17. When a certain dust removal filter element 21 needs to be cleaned, the spraying hood 419 moves to the top of this dust removal filter element 21, and the gas in the gas storage tank 42 is introduced into the spraying hood 419 through the pulse solenoid valve 44 to carry out the pulse reverse spraying and cleaning work. The remaining dust removal filter elements 21 can continue to carry out the dust removal work; the cleaning component 4 of the present utility model uses the pulse reverse spraying method to blow and clean the dust removal filter element 21, sets a movable spraying hood 419 to carry out the pulse reverse spraying work, and carries out the dust removal work through the arranged multiple dust removal filter elements 21. The spraying hood 419 can move to any dust removal filter element 21 for spraying.
