Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of coal mine conveying dust reduction, in particular to a coal mine conveying belt spraying dust reduction device. BACKGROUND

[0002] The coal mine conveying belt spraying dust reduction device is an environmentally friendly device that suppresses the diffusion of dust generated during coal transportation by spraying water mist or chemical dust suppressant. Its core goal is to reduce the dust concentration in the work environment, reduce the risk of explosion, and improve the health conditions of workers.

[0003] When coal mines are de-dusted by a conveying belt, a spraying dust reduction technology is mostly used. Water mist sprayed by spraying heads installed on the conveying belt captures and adsorbs dust particles in the air, making them heavy and sinking, thereby achieving the effect of dust removal.

[0004] Although the above-mentioned conveying belt spraying dust reduction device can better solve the problem of dust, when in use, since the coal forms a conical material pile when falling into the middle of the conveying belt at the dropping point, it causes the thickness of the coal in the middle of the same position of the general conveying belt to be greater than that on both sides. In addition, due to the influence of mine vibration or the influence of the inclined setting of part of the conveying belt, the coal is mostly unevenly distributed on the conveying belt. Continuous quantitative spraying will cause the coal with thinner thickness to be affected by more spraying, resulting in the problem of excessive wetness, which causes the water content to exceed the standard.

[0005] Therefore, the present application proposes a coal mine conveying belt spraying dust reduction device to solve the above problems. SUMMARY

[0022] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, some features described in the examples may be combined in other examples.

[0023] like Figures 1 to 7 As shown, this embodiment provides a conveyor belt spray dust suppression device for coal mine transportation, including a conveyor body 100. Multiple spray heads 101 are arranged above the conveyor body 100. An adjustment mechanism 200 is installed on the conveyor body 100 to adjust the spray volume of the spray heads 101 according to the thickness of the coal. The adjustment mechanism 200 includes a U-shaped frame 201, which is fixedly connected to the conveyor body 100. The spray heads 101 are fixedly connected to the U-shaped frame 201 through connecting pipes. Multiple fixed frames 202 are fixedly connected to the U-shaped frame 201. Each fixed frame 202 has a swinging member 203 rotatably connected to the side away from the U-shaped frame 201. The lower end of the swinging member 203 is perpendicular to the conveyor body 100 and will rotate when pushed by the conveyor body 100 conveying coal.

[0024] The regulating mechanism 200 includes a switch assembly located at the liquid inlet end of the spray head 101. When the swing member 203 rotates, the liquid inlet flow rate of the spray head 101 can be adjusted by the switch assembly.

[0025] The switch assembly includes a connecting pipe 207, which is fixedly connected to a U-shaped frame 201 and communicates with the liquid inlet end of the spray head 101. A sliding baffle 208 is slidably connected inside the connecting pipe 207. A T-shaped connecting rod 205 is slidably connected to the side of the connecting pipe 207 near the swing member 203. The T-shaped connecting rod 205 passes through the connecting pipe 207 and is fixedly connected to the sliding baffle 208. A slider 206 is slidably connected to the side of the T-shaped connecting rod 205 near the swing member 203, and a connecting rod 204 is rotatably connected to the side of the slider 206 near the swing member 203. The connecting rod 204 is rotatably connected to the swing member 203. When the swing member 203 rotates, it can pull the T-shaped connecting rod 205 and the sliding baffle 208 to slide inside the connecting pipe 207 through cooperation with the connecting rod 204 and the slider 206.

[0026] The connecting pipe 207 can be connected to an external infusion tank, through which spray liquid can be provided to the spray head 101.

[0027] Furthermore, the sliding baffle 208 is inclinedly arranged inside the connecting pipe 207. With the inclined sliding baffle 208, the sliding baffle 208 can be better slidably reset by gravity when the conveyor body 100 is not in use or during adjustment.

[0028] Furthermore, the adjustment mechanism 200 also includes a roller 209, which is rotatably connected to the side of the swing member 203 near the conveyor body 100. The lower section of the swing member 203 is longer than the upper section, with the connection point of the fixed frame 202 as the boundary. With this arrangement, according to the lever principle, when the coal mine pushes the lower section of the swing member 203, the switch assembly can be pulled with a smaller force to perform the adjustment work. At the same time, the rotation of the roller 209 can reduce the friction between the lower end of the swing member 203 and the conveyed coal mine, thereby reducing the interference of the adjustment mechanism 200 on the conveyed coal mine during use.

[0029] Further examples: The U-shaped frame 201 is also equipped with an auxiliary mechanism 300, which is used to reduce the moisture content of the coal at the upper edge of the conveyor body 100. The auxiliary mechanism 300 includes two mounting plates 301. The two mounting plates 301 are fixedly connected to opposite sides of the inner wall of the U-shaped frame 201, and the two mounting plates 301 are fixedly connected to support rods 302. Multiple L-shaped fixed rods 303 are fixedly connected to the side of the mounting plate 301 near the support rods 302, and multiple L-shaped sliding rods 304 are slidably connected to the side of the mounting plate 301 near the support rods 302. Each L-shaped sliding rod 304 is fixedly connected to a guide plate 305 near the side of the adjacent L-shaped fixed rod 303. Each L-shaped fixed rod 303 and the adjacent L-shaped sliding rod 304 can form a U-shaped groove through the guide plate 305, and the guide plate 305 is slidably connected to the L-shaped fixed rod 303.

[0030] The L-shaped fixed rod 303 and the L-shaped sliding rod 304 are both arranged in an arc shape, and the height of the L-shaped fixed rod 303, the L-shaped sliding rod 304 and the guide piece 305 away from the mounting plate 301 is greater than the height close to the mounting plate 301.

[0031] The support column 306 is fixedly connected to the side of the support rod 302 close to the L-shaped fixed rod 303, and the sliding column 307 is slidably sleeved on the outer surface of the support column 306.

[0032] The sliding column 307 is fixedly connected to the collar 308 close to the oscillating piece 203, the L-shaped pull column 309 is fixedly connected to the side of the at least two oscillating pieces 203 close to the collar 308, and the L-shaped pull column 309 is movably connected to the collar 308.

[0033] The working principle of all the contents in the above embodiments is as follows: Initial state: the oscillating piece 203 and the conveyor body 100 are in a vertical state, at this time the sliding baffle 208 does not slide in the connecting pipe 207, so that the connecting pipe 207 is in a closed state, and the U-shaped groove formed by the L-shaped sliding rod 304 and the L-shaped fixed rod 303 through the guide piece 305 is also in a maximum opening state.

[0034] The working principle of the adjusting mechanism 200 and its beneficial effects are as follows: When the coal mine is transported, the conveying direction is from left to right, the coal mine is conveyed from the conveyor body 100, and the coal mine with different thicknesses is in contact with the lower end of the oscillating piece 203. Figure 1 When the thickness is greater, the oscillating piece 203 is pushed to rotate at a greater angle, until the roller 209 is above the conveyed coal mine.

[0035] Further, when the oscillating piece 203 rotates with the fixed frame 202 as the shaft, the lower end of the oscillating piece 203 rotates in the direction of the coal mine conveying, and the upper end of the oscillating piece 203 pulls the T-shaped connecting rod 205 to slide away from the connecting pipe 207 through the cooperation of the connecting rod 204 and the sliding block 206, thereby driving the sliding baffle 208 to slide at the same time. At this time, the sliding baffle 208 automatically opens the connecting pipe 207 through the pulling of the T-shaped connecting rod 205, and the thicker the coal mine is, the greater the distance that the oscillating piece 203 pulls the T-shaped connecting rod 205 and the sliding baffle 208 to move through the cooperation of the connecting rod 204 and the sliding block 206, thereby making the spraying amount of the spraying head 101 greater.

[0036] Further, by adjusting the setting of the adjusting mechanism 200, the height difference generated by different thickness of coal during coal conveying is utilized, and under the cooperation of the swing piece 203 and the switch assembly, the spray amount of the spray head 101 can be adjusted according to the different thickness of different coal, and when the thickness decreases, the spray amount also decreases, thereby reducing the water content in unit coal, so that when the thickness of coal increases or decreases, the spray amount of the spray head 101 is adapted to the conveying amount of coal, effectively preventing the problem of excessive water content in coal.

[0037] At the same time, by adjusting the setting of the adjusting mechanism 200, when the coal stops conveying, the swing piece 203 and the obliquely arranged sliding baffle 208 can quickly reset and close the connecting pipe 207 in the first time under the influence of gravity, and the spray amount of the spray head 101 is adjusted according to the conveying amount of coal, effectively avoiding the ineffective consumption and waste of water resources caused by thin coal thick spraying.

[0038] The working principle and beneficial effects of the auxiliary mechanism 300 are as follows: Further, when the adjusting mechanism 200 is in use, the greater the thickness of the coal, the greater the rotation angle of the swing piece 203 to the L-shaped sliding rod 304, and the distance that the swing piece 203 moves to the support rod 302 direction through the cooperation of the L-shaped pull column 309 and the sleeve ring 308 is increased, at this time, the L-shaped sliding rod 304 and the guide piece 305 are pushed to the adjacent L-shaped fixed rod 303, thereby reducing the U-shaped groove composed of the L-shaped sliding rod 304, the guide piece 305 and the L-shaped fixed rod 303, and increasing the distance between the U-shaped grooves, thereby increasing the gap, increasing the contact amount of the spray with the thicker coal, and vice versa, when the coal conveying amount decreases, the gap also decreases, and the contact amount of the spray with the coal also decreases, thereby further preventing the problem of excessive water content in coal.

[0039] In addition, the L-shaped fixed rod 303 and the L-shaped sliding rod 304 are both arranged in an arc shape, the height of the L-shaped fixed rod 303, the L-shaped sliding rod 304 and the guide piece 305 away from the one end of the mounting plate 301 is greater than the height of the one end close to the mounting plate 301, and the mounting plate 301 is hollow, a plurality of liquid inlets are arranged on the side close to the guide piece 305 of the mounting plate 301 and correspond to the U-shaped groove, part of the spray can be collected through the groove body, and the collected spray can enter the mounting plate 301 through the arc arrangement, the collected water mist can be used again after treatment, thereby saving the cost of dust reduction.

[0040] The above describes the embodiments of the present application, but the embodiments are not limited to the above specific embodiments, and the above specific embodiments are only illustrative but not restrictive, and those skilled in the art can make many forms under the inspiration of the embodiments, which all belong to the protection of the embodiments.
