[0029] Embodiment one:
[0030] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 As shown in one kind of coal mine conveying dust removal device, comprising:
[0031] Coal mine conveying mechanism 1 and the feed dust removal mechanism 2 of being assembled on coal mine conveying mechanism 1 and the dust collection mechanism 3 of being assembled on the top of coal mine conveying mechanism 1;
[0032] Coal mine conveying mechanism 1 includes belt conveyor 11, and the top of belt conveyor 11 is fixedly installed with dust cover 12;
[0033] Feed dust removal mechanism 2 includes feed hopper 21 fixedly installed on the top of dust cover 12, the inner wall of feed hopper 21 is connected with conical hopper 24, the center position inside feed hopper 21 is fixedly installed with support cylinder 29, and the top of support cylinder 29 is slidably installed with conical seat 28, and the periphery of feed hopper 21 is fixedly installed with annular dust suction box 22, and the top of feed hopper 21 is fixedly installed with annular guide seat 23;
[0034] Dust collection mechanism 3 includes dust collection box 31 fixedly installed on the top of dust cover 12, and dust collection box 31 is communicated with annular dust suction box 22 and annular guide seat 23.
[0035] From the above, by placing the device in the proper position for use when using, the mined coal is introduced into the belt conveyor 11 from the feed hopper 21 for conveying operation, the dust cover 12 can conveniently avoid dust flying to the outside during the coal conveying process, when the coal is introduced into the feed hopper 21, the annular guide seat 23 can guide the introduced coal, so that the coal can move downward along the center position of the feed hopper 21, the coal can contact with the conical seat 28, the coal can slide downward along the slope of the conical seat 28, and the annular dust suction box 22 can absorb the dust emitted from the side;
[0036] The annular guide seat 23 can cover a certain distance at the edge position of the feeding hopper 21, which can effectively prevent dust from flying vertically upward. At the same time, the annular guide seat 23 can absorb dust from the vertical direction, and can absorb dust in multiple directions in the feeding hopper 21, so that the dust is not easy to fly out from the feeding hopper, and the dust removal effect is effectively improved. The absorbed dust can be sucked into the dust collecting box 31 for collection, which can facilitate subsequent cleaning operation of the collected dust.
[0037] When the coal mine contacts the conical seat 28, the conical seat 28 can be hit to vibrate, which can facilitate the vibration and dispersion of the coal blocks, and can guide the dispersed coal blocks into the conical hopper 24. At the same time, the conical hopper 24 can be hit and vibrated to improve the dispersion effect of the coal blocks, fully release the dust between the coal blocks, and facilitate the full absorption of the dust between the coal blocks by the annular dust suction box 22 and the annular guide seat 23, thereby reducing the dust flying effect of the coal mine in the conveying process.
[0038] By Figure 4 It can be seen that the first vibration spring 25 is connected between the conical hopper 24 and the inner wall of the feeding hopper 21, and the feeding hopper 21 and the support cylinder 29 are fixedly installed through the fixing frame 210.
[0039] As can be seen, when the coal blocks contact the conical hopper 24, the first vibration spring 25 can be extruded to vibrate the conical hopper 24 by the elastic action of the first vibration spring 25, which facilitates the dispersion of the coal blocks. The fixing frame 210 can conveniently support the support cylinder 29, so that the support cylinder 29 can be located at the center position inside the feeding hopper 21.
[0040] Specifically, as shown in Figure 4 The inner wall of the feeding hopper 21 is provided with a plurality of first dust suction holes 26 arranged in a ring array, and the first dust suction holes 26 and the annular dust suction box 22 are in communication.
[0041] As can be seen, the first dust suction holes 26 can conveniently adsorb dust from the side into the annular dust suction box 22.
[0042] Specifically, as shown in Figure 4 The bottom of the annular guide seat 23 is provided with a plurality of second dust suction holes 27 arranged in a ring array, and the second dust suction holes 27 and the first dust suction holes 26 are at right angles.
[0043] As can be seen, the second dust suction holes 27 can absorb dust from the vertical direction into the annular guide seat 23, which can cooperate with the first dust suction holes 26 to absorb dust in multiple directions, thereby improving the dust removal effect.
[0044] Embodiment two:
[0045] Referring to Figure 2 And Figure 3 As shown in the figure, the dust collecting box 31 is communicated with the annular dust collecting box 22 and the annular guide seat 23 through the dust collecting pipe 35, and the front end of the dust collecting box 31 is hinged with a protective door 34.
[0046] As can be seen from the above, the dust collecting pipe 35 can conveniently suck the collected dust in the annular dust collecting box 22 and the annular guide seat 23 into the dust collecting box 31 for unified collection operation, and the protective door 34 can be opened to conveniently clean the collected dust in the dust collecting box 31.
[0047] Referring to Figure 3 As shown in the figure, one side of the dust collecting box 31 is communicated with a fan 32, and the inner wall of the dust collecting box 31 is fixedly installed with a filter cloth 33 corresponding to the fan 32.
[0048] As can be seen from the above, the fan 32 can extract the air in the dust collecting box 31 to produce a negative pressure state in the dust collecting box 31, so that the annular dust collecting box 22 and the annular guide seat 23 can produce a suction force on the feed hopper 21 to conveniently absorb the dust, and the filter cloth 33 can intercept the dust so that the air can pass through, which can avoid the damage caused by the dust being sucked into the fan 32.
[0049] Referring to Figure 5 As shown in the figure, the support cylinder 29 and the conical seat 28 are slidably installed through a movable column 211, and the movable column 211 and the support cylinder 29 are connected with a second vibration spring 212.
[0050] As can be seen from the above, when the coal blocks contact the conical seat 28, the movable column 211 can slide up and down along the support cylinder 29 to produce a pressing effect on the second vibration spring 212, and the elastic action of the second vibration spring 212 can make the movable column 211 push the conical seat 28 to slide up and down quickly to produce a vibration effect, which can conveniently preliminarily scatter the coal blocks, and the conical hopper 24 can fully scatter the coal blocks to release the dust mixed between the coal blocks.
[0051] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
