Description

Technical Field

[0001] The utility model relates to the technical field of dust reduction in mining engineering, and particularly relates to a dust reduction device for mining engineering. Background Art

[0002] As is well known, in the mining industry, especially in the process of underground or open-pit mine exploitation, dust is a common problem. Dust not only affects the normal operation of mechanical equipment, increases wear and failure rate, but also seriously threatens the physical health of workers, such as causing respiratory diseases. Therefore, effective dust reduction measures are crucial for ensuring safe production. After long-term use of traditional filtering equipment, the filter mesh layer is prone to clogging, resulting in a decline in filtering efficiency and hindered air circulation. When replacing or cleaning the filter mesh layer, the entire equipment usually needs to be stopped, which not only affects production efficiency but also increases the complexity and cost of operation. Therefore, it is necessary to propose a solution to this technical problem. Content of the Utility Model

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4, the utility model is a dust reduction device for mining engineering, including a water tank 1 and a dust reduction box 2. The dust reduction box 2 is installed at the top of the water tank 1. Positioning grooves are provided at both ends of the dust reduction box 2, and a filter box 3 is provided on the positioning grooves. A filter opening is provided inside the filter box 3, and a filter mesh layer 4 is provided on the filter opening. A locking mechanism is provided between the positioning groove and the dust reduction box 2. The locking mechanism includes a locking groove and a fastening groove. The fastening groove is opened inside the dust reduction box 2, and a fastening hole is opened between the fastening groove and the positioning groove. The locking groove is opened on one side of the filter box 3. A fastening cone head 5 is provided on the fastening hole. An elastic member 7 is provided between the fastening cone head 5 and the fastening groove. A lifting hole is provided between the locking groove and the top of the filter box 3, and a lifting column 8 is provided on the lifting hole. An inclined block 9 is provided between the lifting column 8 and the locking groove. An air duct 10 is provided between the positioning groove and one side of the dust reduction box 2. A three-way valve 11 is provided between the two air ducts 10. An air inlet pipe 12 is provided on the three-way valve 11. An air outlet frame is provided on one side of the dust reduction box 2. A fan 13 and an atomizing nozzle 14 are provided on the air outlet frame. A water storage cavity is provided inside the water tank 1. A water supply mechanism is provided between the water storage cavity and the atomizing nozzle 14. An inlet mechanism and a drainage mechanism are provided on the water tank 1. In this embodiment, the operator injects water into the water storage cavity inside the water tank 1 through the inlet mechanism, and then places the filter box 3 in the positioning groove. At this time, the fastening cone head 5 is squeezed by the filter box 3 and contracts in the fastening hole. When the filter box 3 abuts against the positioning groove, the locking groove is exactly aligned with the fastening hole. The elastic member 7 in the fastening groove elastically supports the fastening plate 6, so that the fastening cone head 5 is inserted into the locking groove, and thus the filter box 3 is assembled in the positioning groove. By using the three-way valve 11 to open one air duct 10, the fan 13 and the atomizing nozzle 14 are turned on. The water supply mechanism atomizes and sprays water mist to the atomizing nozzle 14. The air inlet pipe 12 sucks the surrounding air into the opened air duct 10, and then enters the filter opening inside the filter box 3 corresponding to the air duct 10. The filter mesh layer 4 blocks the impurities and dust in the air, so that the purified air drives the water mist to blow to the outside through the air outlet frame, and the dust in the mining engineering scene is dust-reduced. After long-term use, more dust and impurities will accumulate on the filter mesh layer 4 in one filter box 3, affecting the air circulation. At this time, the other air duct 10 is opened through the three-way valve 11, and the previously used air duct 10 is closed, so that the filter mesh layer 4 in the other filter box 3 performs the filtering operation. At this time, the previously used filter box 3 can be removed. By pressing the lifting column 8, the lifting column 8 drives the inclined block 9 to move downward. The inclined block 9 contacts and pushes the fastening cone head 5, and the fastening cone head 5 moves into the fastening hole. One end of the fastening cone head 5 leaves the locking groove, so that the filter box 3 can be quickly removed, and the dust reduction operation can be carried out without stopping,It is convenient to replace the filter screen layer 4 in another suspended filter box 3, so that the dust removal efficiency will not be reduced due to the influence of air dust in the mining scene, ensuring the cleanliness of the air entering this structure and improving the dust removal efficiency.

By turning on the water pump 16, the water pump 16 sucks water through the water suction pipe 17 and transports it into the water supply pipe 15, and then sprays water mist through the atomizing nozzle 14, facilitating the dust removal operation.

[0025] In this solution, a liquid level sensor 18 is provided on the inner wall of the water storage cavity. Through the liquid level sensor 18, it is convenient to detect the water storage volume in the water storage cavity, so that personnel can easily know the water storage volume.
