Abstract
Description
Technical Field
[0001] The utility model belongs to the field of mining dust removal, and particularly relates to a dust removal device for mining prevention and control. Background Technique
[0002] Coal mine dust is the main factor leading to pneumoconiosis of workers. At the same time, when there is a large amount of coal dust in the air, it will form an explosive dust cloud and explode under certain conditions, causing serious injuries or even casualties. For preventing and controlling mining dust, methods such as strengthening ventilation, wearing protective equipment, and wet dust removal are usually adopted. The commonly used wet dust removal usually sets up water mist spraying in the mine roadway to adhere and adsorb dust and then let it fall to achieve the purpose of dust removal, which is also a relatively effective dust removal method. However, using wet dust removal in the mine roadway will form mud when the adsorbed and adhered dust and water mist fall to the ground of the mine roadway, affecting the normal passage and construction of workers. Moreover, multiple sets of wet dust removal equipment will form more water mist barriers in the mine roadway. Passing workers need to wear waterproof rain gear outside to prevent their clothes from being wetted by the spraying, which affects work and is relatively inconvenient. Content of the Utility Model
[0003] The purpose of the utility model is to provide a dust removal device for mining prevention and control to solve the technical problems that when using wet dust removal in the mine roadway, the adsorbed and adhered dust and water mist falling to the ground of the mine roadway will form mud, affecting the normal passage and construction of workers, and multiple sets of wet dust removal equipment will form more water mist barriers in the mine roadway. Passing workers need to wear waterproof rain gear outside to prevent their clothes from being wetted by the spraying, which affects work and is relatively inconvenient.

[0016] In order to better understand the purpose, structure and function of the present utility model, the following will make a further detailed description of a dust removal device for mining prevention and control of the present utility model in conjunction with the drawings.
[0017] As Figures 1-5 shown, a dust removal device for mining prevention and control of the present utility model includes a foundation platform 1; columns 2 are oppositely arranged on both sides of the foundation platform 1; a cross beam 3 is connected between the tops of the two columns 2; a support vault 4 is arranged on the upper side of the cross beam 3; a sewage tank 5 is arranged on the lower side of the foundation platform 1 at a position opposite to the cross beam 3; a permeable grille 6 is arranged on the upper side of the sewage tank 5; pedals 7 are symmetrically and rotatably arranged on both sides of the sewage tank 5 of the foundation platform 1; the upper plane of the pedal 7 is flush with the upper plane of the foundation platform 1; a plurality of support springs 8 are arranged between the pedal 7 and the foundation platform 1; a water supply pipe 9 is arranged on one side of the foundation platform 1 and extends upward along the column 2 and is horizontally arranged on the lower side of the cross beam 3; a plurality of nozzles 10 are arranged on the lower side of the water supply pipe 9 at a position opposite to the cross beam 3; a pressing rod 11 is arranged on one side of the pedal 7 and extends to the position of the water supply pipe 9 on one side of the foundation platform 1; a delay-on valve 12 is arranged on the water supply pipe 9 opposite to the pressing rod 11.
[0018] Combined with Figures 1-5 shown, during use, water is supplied to the plurality of nozzles 10 through the water supply pipe 9 for spray dust reduction work, adsorbing and adhering to the dust in the air and then making it fall, having a good effect on removing the dust in the air. At the same time, the water droplets adhering to the dust are collected into the sewage tank 5 through the permeable grille 6 to prevent affecting the working environment in the mine tunnel; the pedal 7 is supported by a plurality of support springs 8, and the delay-on valve 12 is controlled by the pressing rod 11 arranged on one side of the pedal 7, so that when a person walks to the position of this device and steps on the pedal 7, the pedal 7 drives the pressing plate to press the delay-on valve 12 to close the water supply pipe 9, and the nozzles 10 stop spraying water mist. When the person passes through the position of this device, the plurality of support springs 8 push the pedal 7 to reset, the delay-on valve 12 automatically opens, and the nozzles 10 continue to spray water mist for dust reduction work, without the problem that personnel need to carry waterproof rain gear to prevent being wet, which causes inconvenience in work.
[0019] A limit support strip 13 is arranged on the foundation platform 1 relative to the edge of the pedal 7. When a person steps on the pedal 7, the pedal 7 is supported by a plurality of support springs 8 for elastic shock absorption, and the pressing rod 11 driven by the pedal 7 presses the delay-on valve 12 for closing operation to stop the water spraying work of the nozzles 10. At the same time, the pedal 7 moves downward and is supported by the limit support strip 13 for the stepped-on pedal 7 to prevent the pedal 7 from moving down too much and affecting the walking of personnel.
[0020] Two pedals 7 are symmetrically and rotatably arranged on both sides of the sewage tank 5 of the foundation platform 1; water supply pipes 9 are symmetrically arranged on both sides of the foundation platform 1 and extend upward along the column 2 and are horizontally arranged in the middle of the lower side of the cross beam 3; a pressing rod 11 is arranged on one side of the pedal 7 and extends to the position of the adjacent water supply pipe 9 on one side of the foundation platform 1; a delay-on valve 12 is arranged on the water supply pipe 9 opposite to the pressing rod 11.
[0021] By providing two adjacent pedals 7 to control the water supply pipes 9 and nozzles 10 at different positions on both sides, when a person passes by on one side, only the nozzle 10 on the passing side stops working, and the nozzle 10 on the other side continues to work, so that the passing of people will not overly affect the spray dust suppression work. When multiple people pass by and step on the pedals 7 on both sides simultaneously, all nozzles 10 stop operating, enabling the device to allow multiple people to pass through simultaneously. The control of the spraying work of the nozzles 10 is relatively flexible, and the dust removal operation will not be overly affected by the passing of more people.
[0022] It can be understood that the present utility model is described through some embodiments. Those skilled in the art know that without departing from the spirit and scope of the present utility model, various changes or equivalent replacements can be made to these features and embodiments. Additionally, under the teaching of the present utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application belong to the scope protected by the present utility model.
