Description

Technical Field

[0001] This utility model belongs to the field of spray dust suppression technology, specifically relating to a spray dust suppression device for coal mine conveying. Background Technology

[0002] In coal mines, to prevent dust from spreading outwards during transportation, and to prevent dust from falling onto other transmission components and affecting their service life, spraying devices are usually installed on the conveyor belts to suppress dust dispersion. These devices atomize or spray the dust into the conveyor belt, thereby reducing dust levels.

[0003] Most current spraying systems employ spray pipes installed on both sides of the conveyor belt, with nozzles bent at the ends to spray water into the conveyor belt. The spray from these nozzles aims to suppress dust dispersion. However, most existing nozzles are fixedly installed on both sides of the conveyor belt. When the conveyor belt is wide, the spray range of the nozzles on both sides cannot simultaneously meet the dust suppression needs of both the edges and the middle of the conveyor belt, resulting in dust overflow and affecting the dust suppression effect. Utility Model Content

[0004] This utility model provides a spray dust suppression device for coal mine conveyors, which aims to solve the problem that the spraying range of the spray pipes on both sides of the coal mine conveyor belt is limited in the prior art, affecting the dust suppression effect.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a spray dust suppression device for coal mine conveying, comprising:

[0006] A fixed frame, on which a conveyor belt for transporting coal is installed, wherein the conveying direction of the conveyor belt is defined as a first direction and the width direction of the conveyor belt is defined as a second direction;

[0007] A water supply pipe is installed on the side of the fixing frame along the first direction, and the water supply pipe is installed on both sides of the fixing frame;

[0008] A spray pipe is installed on the fixed frame. A nozzle is installed at the end of the spray pipe. The position of the spray pipe on the fixed frame has a degree of freedom to be adjusted along the second direction. Each water supply pipe is connected to multiple spray pipes, and the multiple spray pipes are spaced apart along the first direction.

[0009] In one possible implementation, a mounting bracket is detachably mounted on the fixed frame, and a vertical pole is mounted on the mounting bracket. The position of the vertical pole on the mounting bracket has a degree of freedom to be adjusted in the vertical direction.

[0010] In one possible implementation, the mounting bracket is bent with a base plate, the bottom end of the upright is inserted through the base plate, and the bottom end of the upright is threadedly connected to two limiting members for abutting against the upper and lower sides of the base plate.

[0011] In one possible implementation, a fixing sleeve for fixing a spray pipe is installed at the top of the pole, the spray pipe is slidably disposed inside the fixing sleeve, and a clamping member for tightening the spray pipe is threadedly connected to the side wall of the fixing sleeve.

[0012] In one possible implementation, the fixing sleeve is rotatably disposed at the top of the upright, and the upright is further provided with a drive assembly for driving the fixing sleeve to rotate.

[0013] In one possible implementation, the driving component includes:

[0014] The worm gear is rotatably mounted on the upright.

[0015] The worm gear is fixedly installed on the outside of the fixed sleeve and meshes with the worm.

[0016] In one possible implementation, when the spray pipe is installed on the mounting bracket, the spray direction of the nozzle is tilted downwards.

[0017] In one possible implementation, the water supply pipe is connected to a plurality of water outlet pipes for communicating with the spray pipe, and the water outlet pipes are equipped with control valves for controlling the flow state of the water outlet pipes.

[0018] The solution shown in this application, compared with the prior art, involves setting up a fixed frame, mounting a conveyor belt on the fixed frame, and installing multiple spray pipes on both sides of the conveyor belt, with the multiple spray pipes on each side arranged at intervals along a first direction. Water supply pipes are fixedly installed on the outer walls of both sides of the fixed frame to supply water to the spray pipes. In application, the water supply pipes can be fixed to both sides of the fixed frame, and multiple spray pipes can be installed on both sides of the fixed frame. By adjusting the position of the spray pipes along a second direction, the nozzles on the multiple spray pipes can be arranged at intervals along the second direction. When the conveyor belt is wide, all coal along the width of the conveyor belt can be sprayed by the spray pipes, increasing the spray range. This effectively suppresses dust.

[0024] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] Please refer to the following: Figures 1 to 3 The present invention provides a spray dust suppression device for coal mine conveying. The spray dust suppression device for coal mine conveying includes a fixed frame 1, a conveyor belt 2, a water supply pipe 3, and spray pipes 4. A conveyor belt 2 for conveying coal is installed on the fixed frame 1. The conveying direction of the conveyor belt 2 is defined as the first direction, and the width direction of the conveyor belt 2 is defined as the second direction. The water supply pipe 3 is installed on the side of the fixed frame 1 along the first direction, and water supply pipes 3 are installed on both sides of the fixed frame 1. The spray pipes 4 are installed on the fixed frame 1, and nozzles 41 are installed at the ends of the spray pipes 4. The position of the spray pipes 4 on the fixed frame 1 has a degree of freedom for adjustment along the second direction. Each water supply pipe 3 is connected to multiple spray pipes 4, and the multiple spray pipes 4 are spaced apart along the first direction.

[0026] The dust suppression spraying device for coal mine conveying provided in this embodiment, compared with the prior art, features a fixed frame 1 on which a conveyor belt 2 is mounted. Multiple spray pipes 4 are installed on both sides of the conveyor belt 2, with each side's spray pipes 4 spaced apart along a first direction. Water supply pipes 3 are fixedly installed on the outer walls of both sides of the fixed frame 1, supplying water to the spray pipes 4. In application, the water supply pipes 3 can be fixed to both sides of the fixed frame 1, and multiple spray pipes 4 can be installed on both sides of the fixed frame 1. By adjusting the position of the spray pipes 4 along a second direction, the nozzles 41 on the multiple spray pipes 4 can be spaced apart along the second direction. When the conveyor belt 2 is wide, all coal along the width of the conveyor belt 2 can be sprayed by the spray pipes 4, increasing the spraying range. This effectively suppresses dust.

[0027] Specifically, in this embodiment, when the spray pipe 4 is installed on the fixed frame 1, the spray pipe 4 is located above the conveyor belt 2, and the length direction of the spray pipe 4 is set along the second direction, and the nozzle 41 on the spray pipe 4 is located above the conveyor belt 2.

[0028] In some embodiments, the aforementioned fixing frame 1 may be as follows: Figure 1 , Figure 2 The structure shown. See also... Figure 1 , Figure 2 A mounting bracket 5 is detachably mounted on the fixed frame 1. A vertical pole 6 is mounted on the mounting bracket 5, and the position of the vertical pole 6 on the mounting bracket 5 is adjustable vertically. Mounting holes for the mounting bracket 5 are provided on the fixed frame 1, and the mounting bracket 5 is fixedly mounted on the fixed frame 1 using bolts and nuts. When adding a dust suppression device to the coal mine conveyor belt 2, mounting holes can be machined on the fixed frame 1 according to the actual site conditions, and the mounting bracket 5 can be installed on the fixed frame 1 using bolts and nuts. Appropriate spray pipes 4 can be added according to the actual site conditions.

[0029] Specifically, in this embodiment, when the upright 6 is installed on the mounting frame 5, the axis of the upright 6 is set in the vertical direction, the spray pipe 4 is installed at the top of the upright 6, and the position of the upright 6 can be adjusted in the vertical direction. The height of the spray pipe 4 can be freely adjusted by adjusting the height of the upright 6. In practical applications, the height of the two sides of the conveyor belt 2 is mostly higher than the middle height, and the height of the spray pipe 4 can be adjusted according to the actual installation environment on site.

[0030] In some embodiments, the mounting bracket 5 described above may be as follows: Figure 2 The structure shown. See also Figure 2 The mounting frame 5 has a bent base plate 51. The bottom end of the upright 6 passes through the base plate 51, and the bottom end of the upright 6 is threadedly connected to two limiting members 61, which are respectively used to abut against the upper and lower sides of the base plate 51. The mounting frame 5 is made of bent steel plate. The base plate 51 is bent in the middle of the mounting frame 5, and the mounting plate is bent at the top of the mounting frame 5. The upright 6 includes a sliding rod that is slidably mounted on the mounting plate and a screw rod inserted into the base plate 51. Two limiting members 61, which are nuts, are threadedly connected to the screw rod. The height of the upright 6 can be adjusted by adjusting the position of the two limiting members 61 on the screw rod. The structure is simple and convenient for on-site adjustment. Furthermore, by pressing the two limiting members 61 against the base plate 51, the upright 6 can be fixed to the base plate 51, ensuring the stability of the upright 6's installation position.

[0031] In some embodiments, the aforementioned upright 6 may be adopted as follows: Figure 2 , Figure 3 The structure shown. See also... Figure 2 , Figure 3A fixing sleeve 62 for fixing the sprinkler pipe 4 is installed on the top of the upright 6. The sprinkler pipe 4 is slidably disposed inside the fixing sleeve 62, and a tightening member 621 for tightening the sprinkler pipe 4 is threadedly connected to the side wall of the fixing sleeve 62. When installing the sprinkler pipe 4, first insert the sprinkler pipe 4 into the fixing sleeve 62. After adjusting the position of the sprinkler pipe 4, tighten the tightening member 621 so that the end of the tightening member 621 abuts against the sprinkler pipe 4, thereby fixing the sprinkler pipe 4 inside the fixing sleeve 62.

[0032] Specifically, in this embodiment, the axis of the fixing sleeve 62 is set along the second direction. After the spray pipe 4 is installed inside the fixing sleeve 62, the spray pipe 4 is connected to the water supply pipe 3 by a flexible hose.

[0033] In some embodiments, the aforementioned fixing sleeve 62 may be adopted as follows: Figure 3 The structure shown. See also Figure 3 The fixed sleeve 62 is rotatably mounted on the top of the upright 6, and the upright 6 is also equipped with a drive assembly 7 for driving the fixed sleeve 62 to rotate. A support sleeve for mounting the fixed sleeve 62 is fixedly installed on the top of the upright 6, and the fixed sleeve 62 is rotatably mounted inside the support sleeve. The length of the support sleeve is less than the length of the fixed sleeve 62, and two tightening members 621 are threaded onto each fixed sleeve 62, located on the outer sides of both ends of the support sleeve. In use, the spray pipe 4 can be fixed to the fixed sleeve 62 first, and then the water supply pipe 3 can be activated to supply water to the inside of the spray pipe 4. The water inside the spray pipe 4 is sprayed out through the nozzle 41. During the debugging process, the rotation angle of the fixed sleeve 62 can be adjusted by using the drive assembly 7 according to the spray angle of the nozzle 41 on the spray pipe 4, thereby adjusting the spray angle of the nozzle 41 on the spray pipe 4. Furthermore, when adjusting the angle of the nozzle 41 on the spray pipe 4, it is not necessary to disassemble and reinstall the spray pipe 4. The angle of the nozzle 41 can be adjusted by fixing the spray pipe 4 to the fixing sleeve 62, which makes it more convenient to debug during on-site application.

[0034] In some embodiments, the driving component 7 described above may employ, for example... Figure 3 The structure shown. See also Figure 3 The drive assembly 7 includes a worm gear 71 and a worm wheel 72. The worm gear 71 is rotatably mounted on the upright 6; the worm wheel 72 is fixedly mounted on the outside of the fixed sleeve 62 and meshes with the worm gear 71. A clearance is provided in the middle of the drain top support sleeve to allow the worm wheel 72 to pass, and the worm gear 71 is rotatably mounted on the support sleeve and located within the clearance. When the worm gear 71 is rotated, the fixed sleeve 62 can be driven to rotate inside the support sleeve through the connection with the worm wheel 72. Simultaneously, the worm wheel 72 and the worm gear 71 have a self-locking function, which can fix the position of the fixed sleeve 62 after the angle is adjusted.

[0035] In some embodiments, the spray pipe 4 described above can be as follows: Figure 1 , Figure 2 The structure shown. See also... Figure 1 , Figure 2 When the spray pipe 4 is installed on the fixing frame 1, the spray direction of the nozzle 41 is inclined downwards. A water outlet section is inclined upwards at the end of the spray pipe 4 above the conveyor belt 2. The nozzle 41 is installed on the side of the water outlet section near the conveyor belt 2, with its axis perpendicular to the water outlet section. The water outlet end of the nozzle 41 is located on the side of the nozzle 41 furthest from the water outlet section. When the nozzle 41 sprays water outwards, the water flow direction is downwards along a second direction, which can more effectively act on the coal on the conveyor belt 2, ensuring an effective spray cross-section.

[0036] Preferably, in this embodiment, the nozzle 41 is detachably mounted on the water outlet section of the spray pipe 4, and the axis of the nozzle 41 is inclined downward along the second direction, with the water outlet end of the nozzle 41 located at the bottom end of the nozzle 41. This avoids clogging of the water outlet end of the nozzle 41, and the detachable connection of the nozzle 41 to the water outlet section facilitates future replacement and maintenance of the nozzle 41.

[0037] In some embodiments, the water pipe 3 described above can be as follows: Figure 2 The structure shown. See also Figure 2 Multiple water outlet pipes 8 are connected to the water supply pipe 3, which are used to connect with the spray pipe 4. Control valves are installed on the water outlet pipes 8 to control the flow of water. The multiple water outlet pipes 8 are vertically arranged, with the water outlet end located at the top of the water outlet pipe. The spray pipe 4 and the water outlet pipes 8 are connected by a stainless steel corrugated pipe. Both the water outlet pipe 8 and the spray pipe 4 have external threads for connection to the stainless steel corrugated pipe. The multiple water outlet pipes 8 facilitate the later arrangement of the number of spray pipes 4. The number of spray pipes 4 can be freely increased or decreased according to the actual dust conditions on site. On-site commissioning and installation are more convenient and efficient.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
