Description

Technical Field

[0001] This utility model relates to the field of granite mining technology, and in particular to a granite mining atomization dust suppression device. Background Technology

[0002] Granite is an igneous or igneous rock. Based on their geological formation, rocks can be classified into three categories: igneous rocks, sedimentary rocks, and metamorphic rocks. Granite is an igneous rock, limestone is a sedimentary rock, and marble is a metamorphic rock.

[0003] When mining granite blocks, dust suppression equipment is typically used to spray and control the dust generated during mining. For example, utility model CN222797540U discloses a coal mine dust suppression spray system, which includes a base plate. A water tank is fixedly connected to the upper surface of the base plate, and a water pump is fixedly connected to the upper surface of the water tank. A hose is fixedly connected to the output end of the water pump, and a fixed pipe is fixedly connected to the output end of the hose. A fixed cover is fixedly connected to the outer surface of the fixed pipe, and a water distribution plate is fixedly connected to the right end of the fixed cover. The water pump draws clean water, which is then distributed by the water distribution plate. Through the cooperation of the spray plate and dust suppression nozzles, the clean water is atomized and sprayed out, achieving the effect of dust suppression in the coal mining area. Simultaneously, the cooperation of a forward and reverse motor and a support plate allows the fixed cover to rotate, facilitating workers to adjust the direction of the dust suppression spray and reducing their workload.

[0004] However, in the dust suppression equipment mentioned above, during the process of spraying wastewater to suppress the dust, the contact between the sprayed water mist and the dust particles is limited. As a result, some dust particles pass through the sprayed water mist during the movement of the entire dust suppression equipment, resulting in poor dust suppression effect. Therefore, a granite development using atomized dust suppression equipment is proposed to solve the above problems. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] like Figure 1-4 As shown, the present invention proposes a granite mining atomization dust suppression device, which includes a base plate 1 and a water tank 2 installed on the base plate 1. The water tank 2 is respectively provided with a conveying component 3 for spraying dust suppression and a dust suction component 4 for auxiliary dust suction.

[0029] In this invention, the conveyor 3, in conjunction with the dust suction component 4, blows air behind the water mist during the dust reduction process, allowing the dust particles to come into full contact with the sprayed water mist.

[0030] It should be noted that brake casters are installed at the four corners of the bottom of the base plate 1 to facilitate the operation of the entire dust suppression equipment.

[0031] In an optional embodiment, a pump body 5 is fixedly installed on the inner top wall of the water tank 2, and the front end of the water tank 2 is concave. The conveying component 3 includes a support cylinder 31 fixedly connected to the concave part of the water tank 2. A connecting cylinder 32 is rotatably connected to the upper end of the support cylinder 31, and the upper end of the connecting cylinder 32 is L-shaped. A liquid guide plate 33 is fixedly connected to the L end of the connecting cylinder 32. Ventilation plates 34 are fixedly connected to both the upper and lower sides of the liquid guide plate 33. Several nozzles 35 and air outlets 36 are respectively connected to the side of the liquid guide plate 33 and the ventilation plate 34 away from the connecting cylinder 32. The liquid outlet end of the pump body 5 is connected to a water supply pipe 6 that passes through the water tank 2, the support cylinder 31 and the connecting cylinder 32 in sequence and is connected to the liquid guide plate 33. The liquid inlet end of the pump body 5 is connected to the water flow in the water tank 2 through a pipe fitting. The water inlet end of the pipe fitting is located at the lower end of the inner cavity of the water tank 2. At the same time, a water inlet for adding water is opened on the back of the water tank 2.

[0032] It should be noted that a drive assembly for driving the axial rotation and lifting adjustment of the connecting cylinder 32 is provided between the support cylinder 31 and the connecting cylinder 32.

[0033] In this embodiment, the ventilation plates 34 located on the upper and lower sides of the liquid guide plate 33 can blow air behind the water mist during the spraying process of the liquid guide plate 33 and the nozzle 35, forming a high-speed airflow curtain. This effectively reduces the interference and tearing of the core water mist by the crosswind, allowing the water mist to be sprayed farther and more concentrated. At the same time, when dust particles pass through the water mist, they can also be blown towards the water mist by the blown air, so that the dust particles can fully contact the water mist during the movement adjustment, thereby improving the dust reduction effect.

[0034] The drive assembly includes a lifting cylinder 313 slidably connected to the inside of the support cylinder 31, and a connecting cylinder 32 rotatably connected to the upper end of the lifting cylinder 313. A mounting plate 310 is fixedly connected to the recessed part of the water tank 2, and an electric telescopic rod 311 is fixedly connected to the mounting plate 310. A support plate 37 is fixedly connected to the outer surface of the upper end of the lifting cylinder 313, and the output end of the electric telescopic rod 311 passes through the mounting plate 310 and is fixed to the support plate 37. When the electric telescopic rod 311 is activated, it drives the support plate 37 to rise and fall, thereby driving the lifting cylinder 313 and the connecting cylinder 32 to rise and fall together.

[0035] In addition, an installation chamber 38, which is penetrated by the connecting cylinder 32, is fixedly connected to the support plate 37. A motor 39 is fixedly connected to the lower surface of the installation chamber 38. The output shaft of the motor 39 and the lower end of the connecting cylinder 32 are both fixedly connected to meshing gears 312. The gears 312 are located inside the installation chamber 38, so that the starting motor 39 drives the connecting cylinder 32 to rotate axially at the upper end of the lifting cylinder 313 through the two meshing gears 312.

[0036] Secondly, a guide ring 314 extending to the inner side of the lifting cylinder 313 is fixedly connected to the inner wall of the lower end of the connecting cylinder 32, and the outer diameter of the guide ring 314 is adapted to the inner diameter of the lifting cylinder 313. The guide ring 314 extending into the lifting cylinder 313 can support and guide the lower end of the connecting cylinder 32, so that the connecting cylinder 32 can rotate and adjust stably at the upper end of the lifting cylinder 313.

[0037] In an optional embodiment, the dust collection component 4 includes a fan 48 fixedly mounted on a water tank 2, and a dust collection chamber 41 fixedly connected to the water tank 2. One side of the dust collection chamber 41 is connected to the air inlet of the fan 48. A filter box 42 is slidably placed inside the dust collection chamber 41, and a filter screen 49 is installed on the side of the filter box 42 near the fan 48. Two symmetrically distributed air guide plates 43 are fixedly connected between the ventilation plate 34 and the liquid guide plate 33. Several air inlets 44 are opened on the side of the air guide plate 43 away from the fan 48. A dust collection pipe 45 is connected between the air guide plate 43 and the dust collection chamber 41, and a connecting pipe 46 and a ventilation pipe 47 are connected between the ventilation plate 34 and the fan 48.

[0038] In this embodiment, the adsorption of dust in the air by the liquid guide plate 33 and the air guide plate 43 on the side of the ventilation plate 34 can further reduce the interference and tearing of the core water mist by the side wind, so that the dust particles adsorbed into the dust collection chamber 41 can be filtered and collected by the filter screen 49, thereby reducing dust together with the sprayed water mist and further improving the dust reduction effect.

[0039] It should be noted that the interiors of the liquid guide plate 33, ventilation plate 34 and air guide plate 43 are all hollow, so that the hollow liquid guide plate 33, ventilation plate 34 and air guide plate 43 can be used to guide the blown air and the transported water flow, and then spray the water flow through the nozzle 35, and discharge and absorb the air through the air outlet 36 and air inlet 44 respectively.

[0040] The water supply pipe 6, the dust suction pipe 45, the connecting pipe 46, and the ventilation pipe 47 are all flexible hoses, so that the water supply pipe 6, the dust suction pipe 45, the connecting pipe 46, and the ventilation pipe 47 will not interfere with the rotation and lifting adjustment of the liquid guide plate 33, the ventilation plate 34, and the air guide plate 43.

[0041] The dust collection chamber 41 is conical on the side near the fan 48, and its conical end is connected to the air inlet of the fan 48. The connecting pipe 46 is U-shaped and is connected to the side of the two ventilation plates 34 near the connecting cylinder 32. The ventilation pipe 47 is connected between the connecting pipe 46 and the air outlet of the fan 48. When the fan 48 is started, it will draw air into the dust collection chamber 41 and generate negative pressure inside the dust collection chamber 41. Then, the air can be drawn in through the dust collection pipe 45 and the air inlet 44 on the air guide plate 43. The air is then blown into the ventilation plate 34 through the ventilation pipe 47 and the connecting pipe 46 and discharged.

[0042] The working principle in the above embodiments is as follows:

[0043] After moving the entire equipment to the dust suppression location, the electric telescopic rod 311 can be activated to drive the support plate 37 to rise and fall, thereby driving the lifting cylinder 313 and the connecting cylinder 32 to rise and fall together. This will drive the liquid guide plate 33, ventilation plate 34 and air guide plate 43 at the upper end of the connecting cylinder 32 to rise and fall to the required position. Then, the pump body 5 can be activated to deliver water flow into the liquid guide plate 33 through the water supply pipe 6 to spray water mist to suppress dust. Then, the fan 48 can be activated to blow air into the ventilation plates 34 on the upper and lower sides through the connecting pipe 46 and the ventilation pipe 47, and then blown out through the air outlet 36. This will allow the liquid guide plate 33 to work with the nozzle 35 to blow air behind the water mist during the water mist spraying process, forming a high-speed airflow curtain. This will effectively reduce the interference and tearing of the core water mist by the side wind, allowing the water mist to shoot farther and more concentrated. At the same time, when dust particles pass through the water mist, they can also be blown towards the water mist by the blown air, so that the dust particles can fully contact the water mist during the movement and adjustment.

[0044] The starting motor 39 drives the connecting cylinder 32 to reciprocate axially at the upper end of the lifting cylinder 313 through two meshing gears 312, which in turn drives the liquid guide plate 33, ventilation plate 34 and air guide plate 43 to swing, thereby expanding the dust suppression range.

[0045] The activated fan 48 can draw air from the dust collection chamber 41, creating negative pressure in the dust collection chamber 41. Then, the dust collection pipe 45, together with the air guide plate 43, liquid guide plate 33 and ventilation plate 34, adsorbs the dust particles on the side, which can further reduce the interference and tearing of the side wind on the core water mist, so that the dust particles adsorbed into the dust collection chamber 41 can be filtered and collected by the filter screen 49, thus reducing dust together with the sprayed water mist.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
