[0003] During the use of the existing filter element of the mining diesel engine exhaust purification device, the filter body is supported by a reinforcement structure. Since the size of the reinforcement structure is fixed, when the reinforcement structure is put on the surface of the filter body, when there is a deviation between the two, the filter body cannot be reinforced. Therefore, the utility model proposes a filter element structure for the mining diesel engine exhaust purification device. Utility Model Content

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figures 1 to 3The utility model provides a technical solution: a filter element structure of a mining diesel engine exhaust purification device, comprising a filter body 2, an upper cover 1 arranged at the top of the filter body 2, and a lower cover 3 arranged at the bottom of the filter body 2. The surface of the filter body 2 is symmetrically provided with a reinforcing sleeve 5, which strengthens the filter body 2. The reinforcing sleeve 5 is composed of a sleeve A51, a connecting component 52, and a symmetrically arranged sleeve B53. The sleeve A51 is in contact with one side of the surface of the filter body 2, and the sleeve B53 is in contact with the other side of the surface of the filter body 2. The symmetrically arranged connecting components 52 are respectively arranged at the two ends of the sleeve A51 and the two ends of the sleeve B53. The designed reinforcing sleeve 5 is used to improve the filter element structure of the original exhaust purifier. During use, when the reinforcing structure and the filter body 2 are installed, there is a deviation between the two and the filter body 2 cannot strengthen the filter body 2. By arranging the reinforcing sleeve 5 on the surface of the filter body 2, the filter body 2 is reinforced by the reinforcing sleeve 5. The size of the reinforcing sleeve 5 can be adjusted according to the size of the filter body 2. The size is adjusted so that the two have a fit, thereby ensuring the strengthening effect of the filter body 2. The connecting component 52 is composed of a threaded hole 521, a screw 522, a fixing hole 523, and a limit component 524. The threaded hole 521 is opened on the inner side of one end of the sheath A51 and the inner side of one end of the sheath B53. The fixing hole 523 is opened on the inner side of the other end of the sheath A51 and the inner side of the other end of the sheath B53. The screw 522 is set at the connection between the two ends of the sheath A51 and the two ends of the sheath B53. The end of 522 passes through the fixing hole 523 to the inner side of the threaded hole 521, and the two ends of the sheath A51 are connected to the two ends of the sheath B53 through the symmetrically arranged connecting components 52. The end of the screw 522 and the threaded hole 521 are threadedly connected. The limiting component 524 is arranged at the connection between the screw 522 and the fixing hole 523. The screw 522 is a cylindrical structure. Multiple support rods 4 are arranged around the filter body 2. The two ends of the support rod 4 are respectively fixed to the surface of the upper cover 1 and the surface of the lower cover 3.

[0019] In this embodiment, preferably, the limiting component 524 consists of a limiting groove 5241 and a limiting block 5242.

The limiting groove 5241 and the limiting block 5242 are in a snap-fit ​​state. The cross-section of the limiting block 5242 is a circular structure. The outer diameter of the limiting block 5242 is consistent with the inner diameter of the limiting groove 5241. When the screw 522 moves left and right inside the threaded hole 521 and the fixing hole 523 through the limiting component 524, the limiting block 5242 is synchronously driven to rotate and move inside the limiting groove 5241, which limits the range of movement of the screw 522, so that when the sheath A51 and the sheath B53 are not in use, the screw 522 and the sheath B53 are in a connected state.

[0020] The working principle and usage process of the utility model: During the operation of the mining diesel engine exhaust purification device, the filter element structure arranged inside can effectively adsorb and capture fine particles such as particulate matter, smoke and dust, so as to purify the toxic and irritating gases and particulate matter harmful to the human body in the exhaust gas; when it is necessary to install the reinforced sheath 5 on the surface of the filter body 2, the sheath A51 and the sheath B53 are successively fitted with the two sides of the surface of the filter body 2, and then the connecting components 52 respectively arranged at the two ends of the sheath A51 and the sheath B53 are operated, and the screw 522 is rotated to make the end of the screw 522 threadedly connected to the threaded hole 521, so that the inner wall of the sheath A51 and the inner wall of the sheath B53 are fitted with the surface of the filter body 2, completing the installation of the reinforced sheath 5, thereby strengthening the filter body 2.
