Description

Technical Field

[0001] The invention relates to the technical field of mining dust removal, and in particular to a mining dust suppression device. Background Art

[0002] In the process of mining, a large amount of dust is inevitably generated. In order to ensure construction safety and maintain the cleanliness of the mining environment, it is necessary to use a dust suppression device to deal with the generated dust. When the existing dust suppression device sprays water mist for dust reduction, the atomization area of ​​the atomization structure is small, which makes the efficiency of water mist formation low. The area formed in the air is small and it is difficult to combine with a large amount of dust, resulting in poor dust reduction effect, highlighting the shortcomings of the existing technology. Summary of the invention

[0003] The purpose of the present invention is to provide a dust suppression device for mining, so as to solve the technical problem that the existing dust suppression devices have poor dust suppression effects.

[0004] To achieve the above purpose, the present invention adopts the following technical solutions: A dust suppression device for mining comprises a support frame and a support seat, wherein the left and right parts of the support frame are each slidably connected to a vertical support seat, and the support frame and the support seat are jointly equipped with a lifting mechanism, a plurality of horizontal support cylinders are fixed to the front end of the support seat, a plurality of horizontal nozzles are fixed to the rear part of the support seat, each of the nozzles is connected to each of the support cylinders front to back, and a rear upper part of each of the nozzles is fixedly connected to an intake pipe that is inclined backward and extends, a one-way valve is installed in the intake pipe, and the one-way valve only allows fluid to enter the nozzle through the intake pipe, and an atomizing filter is installed at the front part of the support seat, and the atomizing filter is in a folded shape that reciprocates back and forth.

[0005] On the basis of the above technical scheme, a vertical guide rod is fixed to the bottom of the two support seats respectively, and the two guide rods are respectively slidably connected with a vertical lifting rod, and a vertical No. 1 tension spring is fixed to the bottom of the two lifting rods respectively, and the two No. 1 tension springs are respectively fixed to the bottom of the support seat and are respectively inserted with a gap with the guide rod. Under the action of gravity and the elastic tension of the No. 1 tension spring, the lifting rod has a tendency to slide down along the guide rod, and a vertical No. 1 rack is respectively fixed to the upper part of the two lifting rods, and a vertical screw is respectively fixed to the top. The screw rods are respectively inserted into the upper and lower gaps of the upper part of the support seat, and the upper parts of the two screw rods are respectively threadedly connected with butterfly nuts, and the bottom ends of the butterfly nuts are against the top of the support seat. An annular support frame is fixed to the outer periphery of the atomizing filter, and the outer circumferential wall of the support frame is an incomplete spherical shape. The support frame is rotatably connected to the support tube, and the left and right parts of the support frame are respectively fixed with coaxial support shafts, and the support shaft is rotatably connected to the support tube. A No. 1 gear is coaxially fixed to the support shaft away from the middle part of the support frame, and the No. 1 gear is meshed with a No. 1 rack.

[0006] On the basis of the above technical scheme, the lifting mechanism includes a No. 2 tension spring, a pneumatic reduction motor, an incomplete gear, and a No. 2 rack. The lower left and upper right parts of the support frame are respectively fixed with vertical No. 2 tension springs, and the two No. 2 tension springs are respectively fixed to the two support seats. A horizontal pneumatic reduction motor is fixed to the rear end of the middle part of the support frame. After compressed air is introduced into the pneumatic reduction motor, it rotates clockwise from the main viewing angle. An incomplete gear is coaxially fixed to the rotating shaft of the pneumatic reduction motor, and vertical No. 2 racks are respectively fixed at adjacent ends of the two support seats. The incomplete gear is intermittently meshed with the two No. 2 racks. The support seat on the left part of the support frame has a tendency to slide down along the support frame under the elastic tension of the No. 2 tension spring, and the support seat on the right part of the support frame has a tendency to slide up along the support frame under the elastic tension of the No. 2 tension spring.

[0007] Compared with the prior art, the present invention has the following advantages: the present invention connects a pressurized water source to the rear of the nozzle through a surplus soft pipe, and connects compressed air to the rear of the air inlet pipe through a surplus pneumatic hose, and continuously inputs water and compressed air. At this time, the mixture of compressed air and water converges into the front of the nozzle together, and is sprayed out through an atomizing filter after mixing, thereby forming water mist. Due to the folding structure of the atomizing filter, the contact area with water can be increased, thereby performing efficient atomization operations. The lifting mechanism can make the support seat move back and forth up and down along the support frame, thereby spraying water mist back and forth up and down in the air, thereby increasing the area for intercepting horizontal dust, and then improving the dust reduction effect.

[0013] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] like Figure 1-Figure 4 As shown, a dust suppression device for mining comprises a support frame 1 and a support seat 2, wherein the left and right parts of the support frame 1 are connected with a vertical support seat 2 by sliding up and down, and the support frame 1 and the support seat 2 are jointly equipped with a lifting mechanism 3, and a plurality of horizontal support cylinders 4 are fixed to the front end of the support seat 2, and a plurality of horizontal nozzles 5 are fixed to the rear part of the support seat 2, and each of the nozzles 5 is connected with each of the support cylinders 4 front to back, and each of the nozzles 5 is fixedly connected with an air intake pipe 6 which is inclined backward and extends at the upper rear part, and a one-way valve 7 is installed in the air intake pipe 6, and the one-way valve 7 only allows the fluid to enter the nozzle 5 through the air intake pipe 6, and an atomizing filter 8 is installed at the front part of the support seat 2, and the atomizing filter 8 is in a folded shape which reciprocates back and forth.

[0015] When in use, the sliding direction of the support seat 2 along the support frame 1 is roughly perpendicular to the flow direction of the dust. Assuming that the dust flows horizontally, the support frame 1 is fixed on the vertical side wall of the tunnel or other supports, and then the pressurized water source is connected to the rear of the nozzle 5 through the surplus hose, and the compressed air is connected to the rear of the air inlet pipe 6 through the surplus pneumatic hose. When the dust needs to be settled, water and compressed air are continuously input. At this time, the mixture of compressed air and water is jointly converged into the front of the nozzle 5, and after mixing, it is sprayed out through the atomizing filter 8 to form water mist. Due to the folding structure of the atomizing filter 8, the contact area with water can be increased, thereby performing efficient atomization operations. The lifting mechanism 3 can make the support seat 2 move back and forth up and down along the support frame 1, thereby spraying water mist back and forth up and down in the air, increasing its interception area of ​​horizontal dust, and then improving the dust reduction effect.

[0016] A vertical guide rod 9 is fixed to the bottom of the two support seats 2, and the two guide rods 9 are respectively connected to a vertical lifting rod 10 by sliding up and down. A vertical No. 1 tension spring 11 is fixed to the bottom of the two lifting rods 10, and the two No. 1 tension springs 11 are respectively fixed to the bottom of the support seat 2, and are respectively plugged with the guide rod 9 with a gap. The lifting rod 10 has a tendency to slide down along the guide rod 9 under the action of gravity and the elastic tension of the No. 1 tension spring 11. A vertical No. 1 rack 12 is respectively fixed to the upper part of the two lifting rods 10, and a vertical screw 13 is respectively fixed to the top, and the two screws 13 are respectively connected to the upper part of the support seat 2. The two screw rods 13 are respectively threadedly connected with butterfly nuts 14 on the upper parts, and the bottom ends of the butterfly nuts 14 are against the top of the support seat 2. An annular support frame 15 is fixed on the outer periphery of the atomizing filter 8, and the outer circumferential wall of the support frame 15 is incompletely spherical. The support frame 15 is rotatably connected with the support tube 4. The left and right parts of the support frame 15 are respectively fixed with coaxial support shafts 16, and the support shaft 16 is rotatably connected with the support tube 4. The support frame 15 is coaxially fixed with a No. 1 gear 17 away from the support shaft 16 in the middle of the support frame 1, and the No. 1 gear 17 is meshed with the No. 1 rack 12.

[0017] Furthermore, the lifting rod 10 has a tendency to slide down along the guide rod 9 under the action of gravity and the elastic tension of the No. 1 tension spring 11, and by rotating the butterfly nut 14 to place it in different positions of the screw 13, the upper and lower positions of the lifting rod 10 and the No. 1 rack 12 relative to the support frame 1 can be adjusted, so that the No. 1 gear 17, the support shaft 16 and the support frame 15 can be rotated accordingly, thereby realizing the flipping of the atomizing filter 8, facilitating the cleaning of the scale attached to the front and back of the atomizing filter 8 after long-term use, and ensuring the atomization effect of the atomizing filter 8.

[0018] The lifting mechanism 3 includes a No. 2 tension spring 18, a pneumatic reduction motor 19, an incomplete gear 20, and a No. 2 rack 21. The support frame 1 is respectively fixed with a vertical No. 2 tension spring 18 at the lower left and upper right parts, and the two No. 2 tension springs 18 are respectively fixed to the two support seats 2. A horizontal pneumatic reduction motor 19 is fixed to the rear end of the middle part of the support frame 1. After compressed air is introduced into the pneumatic reduction motor 19, it rotates clockwise from the main viewing angle. An incomplete gear 20 is coaxially fixed to the rotating shaft of the pneumatic reduction motor 19, and vertical No. 2 racks 21 are respectively fixed at the adjacent ends of the two support seats 2. The incomplete gear 20 is intermittently meshed with the two No. 2 racks 21. The support seat 2 on the left part of the support frame 1 has a tendency to slide down along the support frame 1 under the elastic tension of the No. 2 tension spring 18, and the support seat 2 on the right part of the support frame 1 has a tendency to slide up along the support frame 1 under the elastic tension of the No. 2 tension spring 18.

[0019] Furthermore, by introducing compressed air into the pneumatic reduction motor 19, the pneumatic reduction motor 19 can drive the incomplete gear 20 to rotate slowly in the clockwise direction (main viewing angle). When the incomplete gear 20 is engaged with the No. 2 rack 21, the support seat 2 can be dragged to move in the corresponding direction. When the incomplete gear 20 is disengaged from the No. 2 rack 21, the support seat 2 will move in the opposite direction under the elastic tension of the No. 2 tension spring 18, i.e., reset, thereby realizing the alternating up and down reciprocating sliding of the two support seats 2, thereby improving the interception effect of water mist on horizontal dust.

[0020] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
