Description

Technical Field

[0001] The utility model relates to the technical field of explosion relief devices, in particular to a detachable explosion relief device. Background Art

[0002] The occurrence of dust explosion requires certain factors, such as oxygen, combustible dust or dust cloud, fire source, and confined space. When these factors exist at the same time, there is a possibility of explosion. Feed mills, flour mills, tobacco factories, furniture factories, wood board factories, door and window processing factories, etc. are often prone to these factors and are also prone to dust explosion accidents. Since dust explosions are often accompanied by strong shock waves and flames, but the equipment does not have such a strong pressure resistance, the equipment will be damaged when the explosion occurs, and then secondary explosions or multiple explosions will occur. In order to prevent the equipment from causing dust explosions, it is necessary to install an explosion vent in the equipment. The current explosion vent uses threaded connection, which will cause rust and aging after long-term use. It is difficult to disassemble and repair, which is time-consuming and laborious. Therefore, a detachable explosion venting device is proposed, which can be detachably connected with other equipment to facilitate disassembly, maintenance and repair. Utility Model Content

[0029] Example 1

[0030] Reference Figures 1 to 6, which is the first embodiment of the utility model, provides a detachable explosion relief device, which includes an external component 100 and a connecting component 200, wherein the external component 100 includes a wall 101 and a fixing frame 102 disposed on the wall 101; the connecting component 200 is connected to the wall 101, and includes an explosion relief device 201, a base 202 disposed on the explosion relief device 201, a push rod 203 disposed in the base 202, a screw 204 disposed next to the push rod 203, and a push plate 205 connected to the base 202. The fixing frame 102 is concave-shaped, and inner grooves 102a are symmetrically opened on the inner walls on both sides of the fixing frame 102, and the cross section of the inner groove 102a is a triangle, and the inner wall at the bottom of the fixing frame 102 is a horizontal plane. The base 202 is fixedly connected to the explosion relief device 201. The base 202 is symmetrically provided with sliders 202a on both sides. The sliders 202a can be embedded in the inner groove 102a. The base 202 is slidably connected to the fixed frame 102. The slider 202a is provided with a threaded hole 202b. The screw rod 204 is arranged in the threaded hole 202b and is connected by threads. The threaded hole 202b is also connected with a through hole 202c. The through hole 202c is horizontally arranged with the threaded hole 202b, and the through hole 202c extends to the outside of the slider 202a. The push rod 203 is arranged in the through hole 202c. The push rod 203 is slidably connected with the through hole 202c. One end of the push rod 203 facing the inner wall of the slider 202a is a spherical surface. The bottom of the screw rod 204 is conical, and the bottom of the screw 204 abuts against the push rod 203. A limiting cavity 202d is also provided in the center of the slider 202a. The limiting cavity 202d is a rectangular parallelepiped and extends outside the base 202. The push plate 205 is fitted with the inclined surface of the slider 202a. The inclined surface of the push plate 205 has the same inclination angle as the inclined surface of the inner groove 102a. The push plate 205 abuts against the push rod 203. A limiting block 205a is also connected to the push plate 205. The limiting block 205a is slidably connected to the limiting cavity 202d.

[0031] In order to ensure that the explosion relief device 201 can be inserted into the fixing frame 102, the baffle plate 205 is first pushed to fit with the slider 202a, and then the base 202 is embedded in the inner groove 102a, and slides into the fixing frame 102 along the inner groove 102a until the base 202 fits with the bottom of the fixing frame 102. At this time, the explosion relief device 201 is preliminarily installed on the wall 101. In order to fix the explosion relief device 201 in the horizontal direction, the screw rod 204 is screwed to press it down along the thread, and the spherical surface of the push rod 203 is pushed through the conical part at the bottom, so that the push rod 203 moves outward, and the push plate 204 is pushed. 05 can move outward according to the offset distance of the push rod 203 until the push plate 205 fits with the inner groove 102a on the fixing frame 102. At this time, the screw 204 cannot continue to be screwed, and the horizontal fixation of the explosion venting device 201 is completed. In order to make the push plate 205 move horizontally, a limit cavity 202d is set in the slider 202a, so that the push plate 205 and the slider 202a are slidably connected through the limit block 205a. The limit block 205a can keep the push plate 205 moving horizontally, and the inclined surface is parallel to the inclined surface of the inner groove 102a, ensuring that there is no gap inside the device during tightening.

[0032] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
