[0003] A vacuum boiler explosion-proof device, disclosed in CN216281495U, includes a movable flange, a fixed flange, a cooling pipe, and an explosion relief pipe. Two locking blocks are symmetrically fixed to one side of the movable flange and the fixed flange. Two matching slots are symmetrically formed on the side wall of the fixed flange, with the locking blocks resting within the slots. Two symmetrical sliding cavities are formed on the upper side wall of the fixed flange, each containing a sliding block that slides laterally. A locking block is laterally fixedly inserted at the center of each sliding block. One end of each locking block penetrates the side wall of the slot and rests within the locking block; the other end of the locking block is threadedly connected to an adjusting bolt. The other end of the adjusting bolt penetrates the side wall of the fixed flange and is rotatably connected within it. This invention allows for convenient and quick installation and disassembly of the fixed and movable flanges, saving time and effort.

[0004] The existing technology has the following shortcomings: During use, the existing boiler explosion-proof device uses an explosion-proof membrane to release the pressure inside the boiler. After each pressure release, the explosion-proof membrane is damaged and needs to be replaced. It cannot be reused, which increases the labor cost for workers. Utility Model Content

[0005] The purpose of this utility model is to provide an explosion-proof device for boilers. By connecting bolts through the snap-fit ​​plate and the flue and threadedly connecting to the inner wall of the fixing sleeve, the installation mechanism can be stably connected to the flue. The pressure inside the boiler can be released through the gap between the raised pressure relief plate and the cooling pipe. At the same time, the pressure relief plate can be stably reset by the traction spring and damper, which can repeatedly play the role of boiler explosion protection, thereby solving the above-mentioned shortcomings in the technology.

[0029] This utility model provides, for example Figure 1 The explosion-proof device for a boiler shown includes a boiler body 1, and further includes:

[0030] The mounting mechanism 2 is located on the top of the boiler body 1, and the pressure relief mechanism 3 is located inside the mounting mechanism 2.

[0031] To facilitate the connection and fixation of the device to the boiler body 1, such as... Figure 1-3 and Figure 5 As shown, the installation mechanism 2 includes a cooling pipe 201. A fixing sleeve 202 is fixedly installed at the bottom of the cooling pipe 201. Multiple snap-fit ​​plates 204 are evenly spaced at the bottom of the fixing sleeve 202. A connecting bolt 207 penetrating the boiler body 1 is provided between the snap-fit ​​plates 204 and the top of the fixing sleeve 202. The fixing sleeve 202 is fitted onto the top of the boiler body 1. By rotating the snap-fit ​​plates 204, they can contact the bottom of the horizontal part of the boiler body 1. Then, the connecting bolt 207 is used to penetrate the snap-fit ​​plates 204 and the horizontal part of the boiler body 1 and is threadedly connected to the inner wall of the fixing sleeve 202, so that the installation mechanism 2 is tightly connected to the boiler body 1.

[0032] To facilitate pressure relief operations on boiler body 1, such as... Figure 1-3 and Figure 5 As shown, the pressure relief mechanism 3 includes two traction springs 302, which are respectively disposed at both ends of the inner wall of the cooling pipe 201. A pressure relief plate 304 is disposed at the bottom of the two traction springs 302. A damper 305 is movably inserted into the inner side of the traction springs 302. Under the action of pressure, the pressure relief plate 304 is pushed upward along the inner wall of the cooling pipe 201, so that the pressure inside the boiler body 1 can be released from the gap between the lifted pressure relief plate 304 and the top of the cooling pipe 201. When the pressure inside the boiler body 1 is restored, the pressure relief plate 304 is stably reset under the action of the traction springs 302 and the damper 305, so that it can repeat the pressure relief operation of the boiler body 1.

[0033] To ensure a tight connection between the cooling pipe 201 and the flue 101, such as Figure 1-5As shown, the boiler body 1 includes a flue 101. A mounting groove 102 is provided at the top of the flue 101, and a sealing ring 103 is movably installed inside the mounting groove 102. Multiple connecting holes 104 are equally spaced on the outer side of the flue 101. A fixing plate 202 is movably fitted onto the outer side of the top of the flue 101. Multiple fixing seats 203 are fixedly installed at equal intervals at the bottom of the fixing plate 202. The fixing seats 203 are rotatably connected to adjacent snap-fit ​​plates 204. Mounting holes 205 are provided on the inner walls of the multiple snap-fit ​​plates 204. Multiple fixing holes 206 are equally spaced on the top of the fixing plate 202. The inner walls of the mounting holes 205 are flush with the outer walls of adjacent connecting bolts 207. The connection is threaded. The top of the connecting bolt 207 passes through the adjacent connecting hole 104 and is threaded to the inner wall of the adjacent fixing hole 206. The mounting groove 102 can install the sealing ring 103. The sealing ring 103 can seal the fixing sleeve 202 and the flue 101. The snap-fit ​​plate 204 can rotate outside the fixing seat 203 to snap the top horizontal part of the flue 101. The connecting bolt 207 passes through the mounting hole 205 and the connecting hole 104 and is threaded to the inner wall of the adjacent fixing hole 206. Then, a nut is threaded on the top outer side of the bolt to make the fixing sleeve 202 and the flue 101 tightly connected.

[0034] To ensure that the pressure relief plate 304 can perform stable pressure relief operation, such as Figure 2-5 As shown, both ends of the inner wall of the cooling pipe 201 are provided with movable grooves 301. The top of the inner wall of the two movable grooves 301 is fixedly connected to the top of the two traction springs 302, and the top of the inner wall of the two movable grooves 301 is fixedly connected to the top of the two dampers 305. Movable seats 303 are fixedly installed at both ends of the pressure relief plate 304. The top of the movable seat 303 is fixedly connected to the bottom of the adjacent traction spring 302, and the top of the movable seat 303 is fixedly connected to the bottom of the adjacent damper 305. The outer wall of the movable seat 303 is slidably connected to the inner wall of the adjacent movable groove 301. The outer diameter of the pressure relief plate 304 is [not specified]. With the same inner diameter as the cooling pipe 201, the flue 101 is set as a T-shaped structure. The inner diameter of the fixed sleeve 202 is the same as the outer diameter of the top of the flue 101. The movable slot 301 can install and fix the traction spring 302 and the damper 305. The traction spring 302 and the damper 305 can pull the movable seat 303, so that the pressure relief plate 304 can move along the inner wall of the adjacent movable slot 301 through the movable seat 303. This can prevent the pressure relief plate 304 from deviating during the movement and at the same time allow the pressure relief plate 304 to be stably reset.

[0035] When using the explosion-proof device, place the sealing ring 103 into the mounting groove 102 at the top of the flue 101, and then install the mounting mechanism 2 onto the top of the boiler body 1, so that the fixing sleeve 202 is fitted onto the outer side of the top of the flue 101, and the fixing hole 206 on the inner wall of the fixing sleeve 202 can be aligned with the connecting hole 104 at the top of the flue 101. Then, by rotating the snap-fit ​​plate 204, it is rotated from the outward state to the inward state on the outside of the fixing seat 203, so that multiple snap-fit ​​plates 204 can snap onto the bottom of the horizontal part of the flue 101, so that the mounting hole 205 can be aligned with the adjacent connecting hole 104. Then, use the connecting bolt 207 to thread into the mounting hole 205 and pass through the adjacent connecting hole 104 and thread it to the inner wall of the adjacent fixing hole 206. Then, thread a nut onto the outer side of the top of the connecting bolt 207.

[0036] When the internal pressure of the boiler reaches a critical value, the pressure inside the boiler can push the pressure relief plate 304 upward through the flue 101, causing it to move along the inner wall of the adjacent movable slot 301 through the two movable seats 303. This causes the two traction springs 302 and the damper 305 to contract. When the pressure relief plate 304 is higher than the cooling pipe 201, the pressure inside the boiler can be released from the gap between the raised pressure relief plate 304 and the cooling pipe 201. When the pressure inside the boiler returns to normal, the pressure relief plate 304 can stably return to its original position under the elastic force of the traction spring 302 and the traction of the damper 305. This allows for repeated pressure relief and explosion prevention of the boiler. This embodiment specifically solves the problem that the existing technology using explosion-proof membranes cannot repeatedly relieve pressure and prevent explosions in the boiler.

[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
