Description

Technical Field

[0001] The utility model relates to the technical field of mine safety, in particular to a mine spray dust reduction device with a high-efficiency dust reduction function. Background Art

[0002] During the coal mining process, when coal is transported from the coal mining face to other locations via belt conveyors, a large amount of dust will be generated at the transfer point. This is because the speed difference and drop of coal during the transfer process cause the coal dust to be raised, polluting the air and endangering the health of workers. Therefore, in order to reduce dust concentration, improve the working environment and increase safety, the transfer point of the mine belt conveyor needs to use a spray dust reduction device for dust reduction operations.

[0003] In the prior art, for example, the spray dust suppression devices disclosed in publication numbers CN221610031U and CN221896638U have the following defects during use: First, if the angle of the nozzle is fixed, the spray angle range of the nozzle will be small, making it difficult to perform spray dust suppression operations over a large range and efficiently; Second, if the size of the device is large, the device is not suitable for use in narrow spaces and has certain limitations.

[0004] Therefore, how to design a mine spray dust suppression device with high dust suppression function and small size is a problem that needs to be solved urgently by technical personnel in this field. Utility Model Content

[0005] In view of this, the purpose of the utility model is to provide a mine spray dust reduction device with efficient dust reduction function. The spray dust reduction device is small in size and can perform dust reduction operations quickly and efficiently over a large range to solve the technical problems described in the background technology.

[0006] The utility model is realized by the following technical solutions:

[0007] A mine spray dust suppression device with high-efficiency dust suppression function comprises a base, a rotating shaft is rotatably mounted on the base, a sleeve is fixed to one end of the rotating shaft away from the base, and the center line of the sleeve is perpendicular to the center line of the rotating shaft;

[0008] It also includes a position adjustment seat, wherein the position adjustment seat is provided with a strip groove extending therethrough from top to bottom, a spray pipe with a spray head is installed through the strip groove and the sleeve, and a hose is fixedly connected to the spray pipe;

[0009] The adjustment seat is provided with an adjustment mechanism. When the spray pipe rotates around the rotating shaft under the action of the adjustment mechanism, the other end of the spray pipe rotates synchronously to obtain a larger spray dust reduction range.

[0010] Furthermore, the positioning mechanism includes a rack fixedly connected to the positioning seat, a housing is slidably mounted outside the rack, a connector A is fixedly connected to the side of the housing facing the base, and the spray tube is inserted and fixed in the connector A;

[0011] The inside of the shell is fixedly connected with a power source, and the output end of the power source is connected with a gear meshing with the rack.

[0012] Furthermore, the distance between the nozzle and the rotating shaft is greater than the distance between the connector A and the rotating shaft.

[0013] Furthermore, a slide groove is provided on the surface of the base through the front and back, a slider is slidably mounted in the slide groove, and the slider is fixedly connected to the position adjustment seat;

[0014] A screw rod for driving the slider to slide along the height direction of the slide slot is installed on the base, and a knob is fixedly connected to one end of the screw rod extending out of the slide slot.

[0015] Furthermore, the inner diameter of the sleeve is larger than the outer diameter of the spray tube, and a plurality of balls are rotatably mounted on the inner wall of the sleeve, and the surfaces of the balls are in contact with the outer wall of the spray tube.

[0016] Furthermore, a connector B is rotatably mounted on one end of the hose close to the spray pipe, and the connector B is threadedly connected to the spray pipe.

[0017] Furthermore, the adjustment seat is in an arc shape as a whole, and a limiting ring is fixedly connected to the outer wall of the spray pipe. When the limiting ring contacts the sleeve, the center point of the movement trajectory of the shell coincides with the center line of the rotating shaft.

[0018] Furthermore, there are multiple nozzles, and the multiple nozzles are distributed at equal intervals along the length direction of the spray pipe.

[0019] Furthermore, a pair of fixing ears are symmetrically arranged on the side of the base, and the fixing ears are integrally formed with the base.

[0020] The beneficial effects of the utility model are: 1. The distance between the nozzle and the rotating shaft is greater than the distance between the positioning mechanism and the rotating shaft. In this way, when the rotation center of the spray pipe is biased upward, with the rotating shaft as the fulcrum, the upper end of the spray pipe rotates under the action of the positioning mechanism, and the lower end of the spray pipe (the end on which the nozzle is installed) occupies a larger space range. Therefore, the upper end of the spray pipe rotates at a smaller angle, and the lower end of the spray pipe can be flexibly rotated to a larger angle range, thereby obtaining a larger spray dust reduction range, and can quickly and efficiently perform dust reduction operations to ensure the safety of the mining environment.

[0021] 2. The utility model has two spray dust reduction modes. When the center point of the movement trajectory of the positioning mechanism coincides with the center line of the rotating shaft, the spray tube only swings left and right on the vertical plane under the manipulation of the positioning mechanism to perform large-scale spray dust reduction, which is suitable for narrow spaces or single dust source environments;

[0022] When the center point of the movement trajectory of the positioning mechanism does not coincide with the center line of the rotating shaft, the spray tube not only swings on the vertical plane under the movement of the positioning mechanism, but also is subjected to a downward component force, thereby causing the spray tube to slide downward in the sleeve. This movement mode can form a larger range of spray coverage and is suitable for large spaces and complex working environments.

[0023] 3. The base of the utility model is plate-shaped as a whole, and other dust reduction structures are attached to the base. The base can be suspended and installed at the transfer point of the belt conveyor. When materials such as coal are transferred from one device to another and dust is generated, the spray dust reduction device directly acts on the area where the dust is generated. The spray dust reduction device of the utility model has a more compact structure, a smaller size, and a lower cost of use. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes rather than for limiting the present invention.

[0033] In the description of the present application, the terms "upper", "lower", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the structure referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0034] See also Figure 1 The utility model provides a technical solution: a mine spray dust suppression device with high-efficiency dust suppression function, which can be suspended and installed at the transfer point of the belt conveyor. When materials such as coal are transferred from one device to another and dust is generated, the spray dust suppression device directly acts on the area where the dust is generated. The spray dust suppression device includes a base 1, and a pair of fixed ears 17 are symmetrically arranged on the side of the base 1. The fixed ears 17 are integrally formed with the base 1, and the fixed ears 17 are used for the installation of the base 1.

[0035] See also Figure 1 The front surface of the base 1 is rotatably mounted with a rotating shaft 2 through a bearing (not shown), and the rotating shaft 2 is embedded in the inner ring of the bearing. A sleeve 3 is fixed to the end of the rotating shaft 2 away from the base 1, and the center line of the sleeve 3 is perpendicular to the center line of the rotating shaft 2, so that the sleeve 3 can rotate on a vertical plane through the rotating shaft 2;

[0036] It also includes an adjustment seat 4, which is arc-shaped as a whole. The adjustment seat 4 is provided with a strip groove 5 running through it from top to bottom. A spray pipe 6 with a nozzle 7 is installed in the strip groove 5 and the sleeve 3. There are multiple nozzles 7, and the multiple nozzles 7 are evenly spaced along the length direction of the spray pipe 6. The nozzles 7 are used to spray water atomization to reduce dust, thereby ensuring the safety of the mining environment.

[0037] See also Figure 1A hose 8 is fixedly connected to the spray pipe 6, and the spray pipe 6 can be made of stainless steel. Specifically, a connector B15 is rotatably installed at one end of the hose 8 close to the spray pipe 6, and the inner wall of the connector B15 and the outer wall of the spray pipe 6 are respectively provided with threads. The connector B15 is threadedly connected to the spray pipe 6 by screwing, so that the hose 8 and the spray pipe 6 are connected as a whole. The rotation setting of the connector B15 prevents the hose 8 from twisting when rotating. A sealing ring is arranged inside the connector B15 to prevent leakage at the connection between the hose 8 and the spray pipe 6. The connection structure is relatively mature in the prior art and will not be described in detail here.

[0038] See also Figure 1 , Figure 4 and Figure 5 The adjustment seat 4 is provided with an adjustment mechanism 9, which includes a rack 91 fixedly connected to the adjustment seat 4, and a housing 92 is slidably mounted outside the rack 91. Specifically, a notch 18 communicating with the interior of the housing 92 is provided on the housing 92, and the size of the notch 18 matches the width of the rack 91. The housing 92 is slidably mounted on the rack 91 through the notch 18, and the protrusion on the housing 92 extends into the slide groove on the side of the rack 91, so that the housing 92 only moves along the arc direction of the rack 91.

[0039] The shell 92 is fixedly connected with a connector A93 on one side facing the base 1, and the spray pipe 6 is inserted into the connector A93, and the spray pipe 6 is fixed to the connector A93 by bolts on the side of the connector A93, so that when the shell 92 moves, the lower end of the spray pipe 6 can be moved in a circular motion on a vertical plane through the connector A93. At this time, the upper end of the spray pipe 6 swings left and right synchronously with the rotating shaft 2 as the center, so as to obtain a larger spray dust reduction range, and can quickly and efficiently perform dust reduction operations to ensure the safety of the mining environment.

[0040] See also Figure 1 , the distance between the nozzle 7 and the rotating shaft 2 is greater than the distance between the connector A93 and the rotating shaft 2, so that when the rotation center of the spray pipe 6 is biased upward, with the rotating shaft 2 as the fulcrum, the lower end of the spray pipe 6 (the end on which the nozzle 7 is installed) occupies a larger space during the rotation of the spray pipe 6. Therefore, the upper end of the spray pipe 6 rotates at a smaller angle, and the lower end of the spray pipe 6 can be flexibly rotated to a larger angle range, thereby obtaining a larger spray dust reduction range.

[0041] See also Figure 1 , Figure 4 and Figure 5A power source 94 is fixedly connected to the inside of the shell 92. The power source 94 adopts a servo motor in the prior art. The output end of the power source 94 is connected to a gear 95 meshing with the rack 91. When the gear 95 rotates clockwise / counterclockwise under the drive of the power source 94, the gear 95 cooperates with the rack 91 to drive the shell 92 to reciprocate along the arc direction of the adjustment seat 4, thereby driving the spray pipe 6 to swing back and forth on a vertical plane to spray and reduce dust.

[0042] See also Figure 1 and Figure 2 The surface of the base 1 is provided with a slide groove 10 through the front and back, and a slider 11 is slidably mounted in the slide groove 10. The slider 11 can only move up and down under the restriction of the slide groove 10. The slider 11 is fixedly connected to the adjustment seat 4 by screws;

[0043] The base 1 is provided with a screw 12 for driving the slider 11 to slide along the height direction of the slide groove 10. The screw 12 includes a threaded portion and a rod portion, wherein the threaded portion is threadedly connected with the threaded sleeve in the slider 11, and the rod portion is smoothly connected with the base 1. A clamping ring 19 is clamped on the rod portion, and the clamping ring 19 can limit the screw 12 from moving outward when rotating, so as to ensure that the rotation of the screw 12 drives the slider 11 to slide effectively.

[0044] One end of the screw rod 12 extending out of the slide groove 10 is fixedly connected to a knob 13, and a limit ring 16 is fixedly connected to the outer wall of the spray tube 6. When the screw rod 12 is screwed by the knob 13 to drive the slider 11 to slide along the slide groove 10, the vertical position of the adjustment seat 4 can be adjusted. When the position of the adjustment seat 4 is adjusted downward, the spray tube 6 moves driven by the shell 92 and the connector A93. When the spray tube 6 moves so that the limit ring 16 thereon contacts the sleeve 3, the center point of the motion trajectory of the shell 92 coincides with the center line of the rotating shaft 2. At this time, the spray tube 6 only swings left and right on the vertical plane under the manipulation of the adjustment mechanism 9 to perform a large-scale spray dust reduction.

[0045] Secondly, when the limit ring 16 is not in contact with the sleeve 3, the center point of the movement trajectory of the housing 92 does not coincide with the center line of the rotating shaft 2. At this time, the spray tube 6 not only swings on the vertical plane under the manipulation of the positioning mechanism 9, but also receives a downward force component, so that the spray tube 6 slides downward in the sleeve 3. This movement mode can form a wider range of spray coverage. During the up and down movement of the spray tube 6, the dust at different height levels can be sprayed and dusted. Combined with the left and right swing, it can cover a wider horizontal and vertical area, which is conducive to comprehensive dust reduction of dust generated at the material drop above or below the swing plane, reducing the spread of dust into the surrounding environment, and further ensuring the dust reduction effect.

[0046] At the same time, through the cooperation of the knob 13 and the screw 12, the adjustment seat 4 can be driven to slide upward when the spray dust suppression device is not in use, so that the spray pipe 6 can be stored upward, reducing the space occupied by the spray pipe 6, which is convenient for transportation of the spray dust suppression device.

[0047] See also Figure 3 The inner diameter of the sleeve 3 is larger than the outer diameter of the spray tube 6. A plurality of balls 14 are rotatably mounted on the inner wall of the sleeve 3. The surfaces of the balls 14 are in contact with the outer wall of the spray tube 6. The balls 14 convert the sliding friction between the spray tube 6 and the sleeve 3 into rolling friction, thereby reducing the friction during the movement of the spray tube 6 and increasing the service life of the spray tube 6.

[0048] Finally, it should be noted that the above-mentioned implementation is only a preferred implementation of the utility model, and cannot be used to limit the scope of protection of the utility model. Any non-substantial changes and substitutions made by technicians in this field on the basis of the utility model are within the scope of protection required by the utility model.
