[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Example 1, referring to Figures 1-4This is the first embodiment of the present invention. This embodiment provides a mine diesel engine exhaust gas purification device, which can facilitate the quick disassembly of the exhaust gas purifier body 10. It includes a support component, including the exhaust gas purifier body 10 and a mounting plate 11. An air inlet 12 is fixedly connected to the left end of the exhaust gas purifier body 10, and an exhaust outlet 13 is fixedly connected to the right end of the exhaust gas purifier body 10. The exhaust gas purifier body 10 is composed of two parts and is connected by a flange, which facilitates the disassembly and assembly of the filter element of the exhaust gas purifier body 10 or the maintenance of the exhaust gas purifier body 10. A positioning frame 14 is fixedly connected to the top of the mounting plate 11. Two through slots are symmetrically opened inside the mounting plate 11. By passing threaded fasteners through the through slots, it is convenient to install the mounting plate 11 on the mine car. A positioning component 15 for supporting the exhaust gas purifier body 10 is provided on the outside of the exhaust gas purifier body 10, and a limit component 16 is provided on the outside of the positioning component 15.

[0025] Specifically, the positioning component 15 includes a U-shaped frame 151, which is fixedly connected to the outside of the exhaust gas purifier body 10. The U-shaped frame 151 is slidably connected to the top of the mounting plate 11 and to the inner wall of the positioning frame 14. A housing 152 is fixedly connected to the outside of the U-shaped frame 151. A sliding plate 153 is slidably connected to the inner wall of the housing 152. An insert plate 154 is fixedly connected to the bottom of the sliding plate 153 and is slidably connected to the housing 152 and the U-shaped frame 151. A sliding rod 155 is fixedly connected to the top of the sliding plate 153. The top of the sliding plate 153 is connected to the housing 152 and the U-shaped frame 151. A spring 156 is fixedly connected between the bodies 152, and a lifting plate 157 is fixedly connected to the top of the slide rod 155. The mounting plate 11 is installed on the mine car by using threaded fasteners. The positioning of the exhaust gas purifier body 10 is completed by sliding the U-shaped frame 151 on the inner wall of the positioning frame 14. By raising the handle 163 to a certain height and away from the arc block 164, the slide plate 153 moves downward under the elastic action of the spring 156, so that the insert plate 154 is inserted into the groove opened inside the mounting plate 11, limiting the U-shaped frame 151, thereby completing the quick installation of the exhaust gas purifier body 10.

[0026] Furthermore, the mounting plate 11 has a groove at the position corresponding to the insertion plate 154, and the insertion plate 154 is inserted into the groove, which facilitates the quick positioning of the exhaust gas purifier body 10.

[0027] The housing 152 has a through hole at the position corresponding to the slide rod 155, and the slide rod 155 is slidably connected in the through hole to facilitate the lifting and lowering of the slide rod 155.

[0028] Preferably, the limiting component 16 includes a vertical block 161, which is fixedly connected to the top of the lifting plate 157. A rotating column 162 is rotatably connected inside the vertical block 161, and a handle 163 is fixedly connected to the outside of the rotating column 162. An arc-shaped block 164 is fixedly connected to the front of the U-shaped frame 151. The handle 163 contacts the arc-shaped block 164. The handle 163 facilitates the movement of the lifting plate 157 by the operator. With the cooperation of the arc-shaped block 164, the lifting handle 163 is limited to prevent the plate 154 from moving down, thus facilitating the stable placement of the U-shaped frame 151.

[0029] In use, the mounting plate 11 is installed on the mine car using threaded fasteners. The U-shaped frame 151 is slid against the inner wall of the positioning frame 14 to complete the positioning of the exhaust gas purifier body 10. By raising the handle 163 to a certain height and moving it away from the arc block 164, the slide plate 153 moves downward under the elastic action of the spring 156, so that the insert plate 154 is inserted into the groove opened inside the mounting plate 11, limiting the U-shaped frame 151, thereby completing the quick installation of the exhaust gas purifier body 10. When it is necessary to disassemble and maintain the exhaust gas purifier body 10, the handle 163 is pulled upward, and the handle 163 is limited with the cooperation of the arc block 164, making it easy to pull the U-shaped frame 151 out of the positioning frame 14 and quickly disassemble the exhaust gas purifier body 10.

[0030] Example 2, refer to Figures 5-6 This is the second embodiment of the present utility model. Unlike the previous embodiment, this embodiment provides a stabilizing component for the exhaust gas purification device of the mining diesel engine based on the first embodiment. This solves the problem of inconvenience in maintaining the exhaust gas purifier body 10. The stabilizing component includes a support rod 20, and a rotating component 21 is provided on the outside of the support rod 20.

[0031] Specifically, the rotating assembly 21 includes a rotating rod 211, which is fixedly connected to the outside of the support rod 20. The rotating rod 211 is rotatably connected to the U-shaped frame 151. An extension block 212 is fixedly connected to the outside of the rotating rod 211. A sleeve 213 is fixedly connected to the bottom of the lifting plate 157. The sleeve 213 is slidably connected to the support rod 20. A support leg 214 is fixedly connected to the outside of the support rod 20. A pad block 215 is fixedly connected to the end of the support leg 214 away from the support rod 20. The sleeve 213 facilitates... The support rod 20 is positioned to limit the movement of the exhaust gas purifier body 10. When the exhaust gas purifier body 10 needs to be disassembled and the filter element replaced, the support rod 20, the support leg 214 and the pad 215 are used to support the disassembled exhaust gas purifier body 10, ensuring the stability of the disassembled exhaust gas purifier body 10 and facilitating the replacement of the filter element or the cleaning of the exhaust gas purifier body 10. The extension block 212 is used to facilitate the positioning of the insertion plate 154, thereby facilitating the limiting of the support rod 20.

[0032] Furthermore, the extension block 212 has a groove at the position corresponding to the insertion plate 154, and the insertion plate 154 is inserted into the groove. The side of the insertion plate 154 contacts the groove to ensure that the support rod 20 does not rotate.

[0033] In use, by raising the handle 163 to a suitable height, the sleeve 213 is moved away from the support rod 20, thereby releasing the restriction on the support rod 20. The support rod 20 is rotated 90 degrees, causing the rotating rod 211 to rotate, which in turn causes the extension block 212 to rotate, making the pad block 215 contact the ground. By releasing the handle 163, the insert plate 154 moves downward, allowing the insert plate 154 to be inserted into the groove inside the extension block 212, thus limiting the rotation of the support rod 20 and providing auxiliary support for the exhaust gas purifier body 10. This facilitates the disassembly of the exhaust gas purifier body 10 with tools, making it convenient to replace the filter element or clean the exhaust gas purifier body 10.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
