Description

Technical Field

In order to protect the health of workers and prevent safety accidents, coal mines do need to remove dust during coal mining, and wet dust removal equipment is widely used in coal mines.

[0033] See also Figure 1-Figure 3 The coal mine dust removal device 100 includes a housing 10, a dust scraping mechanism 20, a dust filtering mechanism 60 and an air suction mechanism 40. The dust scraping mechanism 20, the air suction mechanism 40 and the dust filtering mechanism 60 are all arranged in the housing 10. When the coal mine dust removal device 100 is working, the air suction mechanism 40 drives the external gas to pass through the housing 10. When the gas passes through the housing along with the particles, the gas can be discharged to the outside through the dust filtering mechanism 60. The dust filtering mechanism 60 can filter or block the particles so that the particles accumulate in the dust filtering mechanism 60. When the particles accumulate to a preset amount, the accumulated particles are cleaned by the dust scraping mechanism 20 to realize automatic cleaning of the particles.

[0034] For the above-mentioned box 10, please refer to Figure 2 Combination Figure 3The box body 10 is provided with an inner cavity 10a, an air inlet 10b and an air outlet 10c, and the air inlet 10b and the air outlet 10c are both connected to the inner cavity 10a. The air inlet 10b is located on the side wall of the inner cavity 10a, and the air suction mechanism 40 is arranged at the air inlet 10b; the air outlet 10c is located at the bottom of the box body 10, and the dust filter mechanism 60 is closed and covered on the air outlet 10c.

[0035] In order to better and more clearly describe the coal mine dust removal device 100, the present invention introduces a first direction x, a second direction z and a third direction y which are perpendicular to each other.

[0036] For the above-mentioned dust scraping mechanism 20, please refer to Figure 2 Combination Figure 3 and Figure 4 The dust scraping mechanism 20 includes a driving component 21, a dust scraping component 22 and a dust collecting component 24. The dust collecting component 24 is connected to the dust filtering mechanism 60, and the dust collecting component 24 is located below the dust filtering mechanism 60. The dust collecting component 24 and the wall of the inner cavity 10a together enclose a dust collecting groove 20a. The driving component 21 is connected to the dust scraping component 22, and one end of the dust scraping component 22 is slidably arranged on the wall of the inner cavity 10a, and the other end of the dust scraping component 22 is against the bottom of the dust collecting groove 20a. When the dust scraping mechanism 20 cleans the accumulated particles, the driving component 21 drives the dust scraping component 22 to reciprocate along the dust collecting groove 20a, so that the dust scraping component 22 scrapes the accumulated particles, thereby achieving the effect of cleaning the accumulated particles. Among them, the direction of the reciprocating movement of the dust scraping component 22 along the dust collecting groove 20a is the first direction x.

[0037] For the above-mentioned dust scraping assembly 22, please refer to 4 in conjunction with Figure 5 The dust scraping assembly 22 includes a dust scraping member 221, a first connecting rod 225 and a second connecting rod 226. One end of the first connecting rod 225 is connected to the driving shaft of the driving assembly 21, the other end of the first connecting rod 225 is provided with a sliding portion 225a, the second connecting rod 226 is provided with a sliding groove 226a along the second direction z, the sliding portion 225a is inserted into the sliding groove 226a, the dust scraping member 221 is slidably connected to the wall surface of the inner cavity 10a, and the dust scraping member 221 is installed on the second connecting rod 226. In this embodiment, the driving assembly 21 is a motor. When the driving shaft of the driving component 21 rotates, the first connecting rod 225 makes a circular motion with the driving shaft of the driving component 21 as the center, and the sliding portion 225a of the first connecting rod 225 reciprocates along the sliding groove 226a of the second connecting rod 226, so that the second connecting rod 226 reciprocates along the first direction x, and the dust scraping member 221 synchronously accompanies the second connecting rod 226 to reciprocate along the first direction x, thereby scraping the particles accumulated in the dust collecting groove 20a.

[0038] This embodiment provides a preferred implementation in which the second connecting rod 226 is slidably connected to the side wall of the inner cavity 10a. Specifically, the wall surface of the inner cavity 10a is provided with a guide rail 13, and the second connecting rod 226 is provided with a guide groove 10f, and the guide rail 13 is inserted into the guide groove 10f.

[0039] Preferably, the scraper 221 includes a mounting portion and a brush, one end of the mounting portion is connected to the nut, and the brush is disposed at the other end of the mounting portion, and the brush corresponds to the bottom wall of the dust collecting tank 20a.

[0040] Preferably, the scraper 221 is made of a flexible material, such as rubber or silicone.

[0041] In some embodiments, the scraper 221 flexibly abuts against the bottom wall of the dust collecting trough 20a. Specifically, along the second direction z, the second connecting rod 226 is provided with a guide groove; the scraper 221 is provided with a clamping portion, which is plugged into the guide groove and can slide along the guide groove; the scraper assembly 22 includes an elastic member, one end of which is connected to the second connecting rod 226, and the other end of which is connected to the scraper 221. As the scraper 221 reciprocates relative to the bottom wall of the dust collecting trough 20a for a long time, the scraper 221 will be worn, so that there is a gap between the scraper 221 and the bottom wall of the dust collecting trough 20a, so that the cleaning effect of the scraper 221 is not good, and under the action of the elastic member, the elastic member always maintains a state of providing thrust, reducing the gap between the scraper 221 and the bottom wall of the dust collecting trough 20a, and increasing the cleaning effect of the scraper 221.

[0042] In some embodiments, the elastic member is a spring. Preferably, the dust scraping assembly 22 further comprises a sleeve, which is sleeved on the spring and connected to the dust scraping member 221. Along the radial direction of the spring, the sleeve can reduce the risk of the spring being deflected.

[0043] In some embodiments, the dust scraping mechanism 20 further includes a collection box 23, see Figure 6 The collecting box 23 is disposed on the housing 10. The collecting box 23 is provided with a collecting chamber 23a and a dust inlet 23b. The collecting chamber 23a is connected to the dust inlet 23b. The housing 10 is provided with a dust outlet 10d. The dust inlet 23b corresponds to the dust outlet 10d. When the scraping assembly 22 scrapes the accumulated particles along the first direction x, the particles sequentially pass through the dust outlet 10d and the dust inlet 23b and fall into the collecting chamber 23a, thereby collecting the particles.

[0044] For the above-mentioned dust filter mechanism 60, please refer to Figure 4 Combination Figure 7The dust filter mechanism 60 includes a vibration component 61, a filter component 62 and a filter mounting plate 63.

When the coal mine dust removal device 100 is working, particulate matter accumulates in the filter component 62 of the dust filter mechanism 60. By stopping the air suction mechanism 40, the external gas stops entering the inner cavity 10a, the vibration component 61 can generate vibration force, and provide vibration force to the filter mounting plate 63, so that the particulate matter in the filter component 62 is shaken off into the dust collecting trough 20a.

[0045] In some embodiments, see Figure 1 The dust filter mechanism further includes an elastic sheet 64. One end of the elastic sheet 64 is rotatably connected to the filter mounting plate 63, and the other end of the elastic sheet 64 abuts against the filter assembly 62. When the filter assembly 62 is installed, the elastic sheet 64 is rotated so that the elastic sheet 64 generates elastic interference with the filter assembly 62, and the elastic sheet 64 and the filter mounting plate 63 jointly clamp the filter assembly 62, thereby achieving the effect of stabilizing the filter assembly 62.

[0046] For the above filter mounting plate 63, see Figure 7The filter mounting plate 63 includes a plate body 631 , a first horizontal bar 632 , a second horizontal bar 633 , a first vertical bar 634 and a second vertical bar 635 . The plate body 631 has a first side 631a, a second side 631b, a third side 631c and a fourth side 631d connected end to end. The first side 631a of the plate body 631 is arranged opposite to the third side 631c of the plate body 631, the second side 631b of the plate body 631 is arranged opposite to the fourth side 631d of the plate body 631, the air inlet 10b is located near the third side 631c of the plate body 631, the dust collecting member 24 is connected to the first side 631a of the plate body 631, one end of the first horizontal bar 632 and one end of the second horizontal bar 633 are respectively connected to the second side 631b of the plate body 631 and the fourth side 631d of the plate body 631, and the other end of the first horizontal bar 632 and the other end of the second horizontal bar 633 extend toward the middle of the plate body 631, one end of the first vertical bar 634 is connected to the other end of the first horizontal bar 632, and one end of the second vertical bar 635 is connected to the The other end is connected to the other end of the second horizontal bar 633, the other end of the first vertical bar 634 and the other end of the second vertical bar 635 extend toward the first side 631a of the plate body 631 respectively, so that the plate body 631, the first horizontal bar 632, the second horizontal bar 633 and the wall surface of the inner cavity 10a together form the first filter groove 60a, the plate body 631, the first horizontal bar 632, the first vertical bar 634 and the wall surface of the inner cavity 10a together form the second filter groove 60b, the plate body 631, the second horizontal bar 633, the second vertical bar 635 and the wall surface of the inner cavity 10a together form the third filter groove 60c, the plate body 631, the first vertical bar 634 and the second vertical bar 635 together form the slide groove 60d, part of the through holes 63a are arranged in the first filter groove 60a, and the other part of the through holes 63a are respectively arranged in the second filter groove 60b and the third filter groove 60c.

[0047] In this embodiment, there are multiple elastic sheets 64, some of which are arranged on the first horizontal bar 632 and the second horizontal bar 633, and the other part of the elastic sheets 64 are arranged on the first vertical bar 634 and the second vertical bar 635. The elastic sheet 64 located at the first horizontal bar 632 can press the first filter element and the second filter element, the elastic sheet 64 located at the second horizontal bar 633 can press the first filter element and the third filter element, the elastic sheet 64 located at the first vertical bar 634 presses the second filter element, and the elastic sheet 64 located at the second vertical bar 635 presses the third filter element.

[0048] For the above filter assembly 62, see Figure 7, the filter assembly 62 includes a first filter element 621, a second filter element 622 and a third filter element 623. The first filter element 621 is installed in the first filter slot 60a, the second filter element 622 is installed in the second filter slot 60b, and the third filter element 623 is installed in the third filter slot 60c. When the vibration assembly 61 provides vibration force to the filter mounting plate 63, the particles collected in the first filter element 621 are shaken down from top to bottom along the chute 60d to the dust collecting slot 20a, and the first horizontal bar 632 and the second horizontal bar 633 can guide the particles to fall into the chute, that is, the first horizontal bar 632 and the second horizontal bar 633 guide the particles to fall into the chute 60d, and the particles collected in the second filter element 622 and the third filter element 623 are directly shaken down to the dust collecting slot 20a, and the first horizontal bar 632 and the second horizontal bar 633 have a limiting effect on the first filter element 621.

[0049] In some embodiments, the filter element comprises a plurality of stacked cloth pieces, wherein the plurality of cloth pieces are knitted and sewn together. In some further embodiments, the filter element comprises a plurality of stacked filter cottons or filter nets.

[0050] In some embodiments, the through hole 63a located in the first filter tank 60a is smaller than the through hole 63a located in the second filter tank 60b and the third filter tank 60c. It is understandable that when the gas in the inner cavity 10a is discharged to the outside, the flow rate through the second filter tank 60b and the flow rate through the third filter tank 60c is greater than the flow rate of the first filter tank 60a. When the external gas enters the inner cavity 10a from the air inlet, the gas first collides with the wall surface of the inner cavity 10a on the first side 631a close to the plate body 631, and the heavier particles fall into the dust collecting tank 20a, the second filter element 622 and the third filter element 623 respectively, and the lighter particles fall into the first filter element 621.

[0051] The above-mentioned coal mine dust removal device 100 also includes a spray mechanism 30, see Figure 1 The spray mechanism 30 is disposed in the inner cavity 10a. The spray mechanism 30 can generate water mist, which can increase the weight of the particles.

The first water pump 34 is disposed in the first pipe 32, one end of the first pipe 32 is connected to the water tank 31, and the other end of the first pipe 32 is connected to the spray element 33, and the spray element 33 is disposed in the inner cavity 10a. When the spray mechanism 30 is working, by placing a preset volume of fluid in the water tank 31, the first water pump 34 pushes the fluid in the first pipe 32 to move, and the water is transported from the water tank 31 to the spray element 33 through the first pipe 32, and the spray element 33 processes the water to form a water mist.

The mounting member 41 is disposed at the air inlet 10b, the blade 42 is rotatably connected to the mounting member 41, and the motor 43 is connected to the blade 42. When the air suction mechanism 40 is working, the motor 43 drives the blade 42 to rotate, so that the external gas enters the inner cavity 10a through the air inlet 10b.

[0056] In some embodiments, the air suction mechanism 40 further includes a protective cover, which covers the air inlet 10b. When the coal mine dust removal device 100 stops working, the protective cover covers the air inlet 10b to reduce the risk of larger objects entering the inner cavity 10a from the outside through the air inlet 10b.

[0057] In the embodiment of the present application, the coal mine dust removal device 100 includes a box body 10, an air suction mechanism 40, a dust filtering mechanism 60 and a dust scraping mechanism 20.
