Description

Technical Field

[0001] This utility model belongs to the field of chemical safety technology, and in particular to a safe explosion-proof structure for a chemical reaction vessel. Background Technology

[0002] A reaction vessel is a comprehensive reaction container. The design of its structure, function, and accessories is based on the reaction conditions. During operation, to balance the internal pressure, venting is necessary. Traditional venting methods cannot automatically regulate the stability of the internal pressure, resulting in poor safety. Excessive internal pressure can easily lead to overpressure, affecting normal operation and potentially causing an explosion. Existing explosion-proof structures for chemical reaction vessels, while ensuring stable pressure by venting the gas and treating it with adsorption components to protect workers' health, still require time-consuming and labor-intensive replacement of the adsorption material, which is bolted to the inside of the collection frame.

[0003] A search revealed a Chinese patent document (authorization announcement number CN219217490U), which discloses a safety explosion-proof structure for a chemical reactor, belonging to the field of chemical safety technology. The device includes a collection frame screwed onto the outside of the reactor body and a venting pipe connected to the collection frame. The collection frame is annular with a hollow interior. One end of the venting pipe extends into the collection frame, and the other end connects to the inside of the reactor body. Two venting pipes are symmetrically arranged about the reactor body. A partition plate is fixed inside the collection frame, dividing the internal space into an outlet area and a filtration and adsorption area. This explosion-proof structure can automatically release pressure when the pressure in the reactor is too high and can treat the gas discharged after pressure release, reducing the risk of pollution. While this patent protects the health of workers to some extent, the adsorption material is bolted to the inside of the collection frame, making its replacement time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of this invention is to provide a safe and explosion-proof structure for chemical reaction vessels to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a safe and explosion-proof structure for a chemical reactor, comprising a reactor body and an installation box installed on the side of the reactor body. The side of the installation box is equipped with a treatment component to ensure the safety and explosion-proof properties of the reactor body. Two adjusting rods are slidably connected to the inner wall of the installation box, and an open-type support frame is fixedly connected between the two adjusting rods. The top of the support frame has multiple through holes to facilitate gas flow. An adsorption plate for adsorbing harmful chemical gases is placed inside the support frame, and a sealing plate for bonding sealing gaskets is fixedly connected to the side of the support frame. An installation plate is fixedly connected to the side of the installation box, and a drive shaft is rotatably connected to the side of the installation plate. A drive motor that provides power to the drive shaft is installed on the side of the installation plate. A linkage plate is fixedly connected to one end of the drive shaft, and a fixed end of an electric push rod is installed on the side of the linkage plate. The driving end of the electric push rod passes through the connecting plate and is fixedly connected to a positioning plate that limits the position of the sealing plate.

[0006] Preferably, the processing component includes a connecting pipe extending through the side of the mounting box and a limiting box installed at the bottom of the connecting pipe.

[0007] Preferably, the top of the mounting box is provided with an exhaust port.

[0008] Preferably, a piston is slidably connected to the inner side of the connecting pipe, and a movable plate that penetrates and connects to the connecting pipe is fixedly connected to the side of the piston. A pressure relief hole is provided on the outer periphery of the connecting pipe.

[0009] Preferably, a reset spring is fixedly connected to the inner side of the limiting box, and one end of the reset spring is fixedly connected to a movable plate connected to the inner wall of the limiting box.

[0010] Preferably, the side of the movable plate is connected and fixed to the movable plate.

[0011] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0012] This chemical reactor features a safe and explosion-proof structure. Thanks to the design of the drive motor and processing components, the positioning plate is released from the pressure on the sealing plate by activating the electric push rod. Then, the drive motor rotates the linkage plate (until it is parallel to the vertical of the mounting box), allowing the sealing plate to be pulled out and the adsorption plate to be replaced. This makes the replacement of the adsorption plate more convenient. Compared with the replacement method of existing devices, the replacement of the adsorption plate in this device is more time-saving and labor-saving. In addition, the design of the processing components can achieve an automatic pressure relief effect, thus achieving a safe and explosion-proof effect.

[0013] The chemical reactor has a safe and explosion-proof structure, which facilitates the replacement of the adsorption plates, making the replacement operation more time-saving and labor-saving. Attached Figure Description

In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0023] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0024] The connection method can adopt existing methods such as bonding, welding, bolting, etc., depending on the actual needs. Techniques, methods and equipment known to those skilled in the art may not be discussed in detail. However, where appropriate, the techniques, methods and equipment should be regarded as part of the specification. The proportions of the components in the drawings are for reference only and can be adjusted to a certain extent according to the actual use.

[0025] Examples, such as Figures 1 to 5 As shown, the reactor includes a reactor body 1 and a mounting box 2 installed on the side of the reactor body 1. The reactor body 1 is based on existing mature technology; please refer to the prior art for details. The side of the mounting box 2 is equipped with a treatment component 3 to ensure the safety and explosion-proof properties of the reactor body 1. Two adjusting rods 7 are slidably connected to the inner wall of the mounting box 2. An open-type support frame 5 is fixedly connected between the two adjusting rods 7, and the top of the support frame 5 has multiple through holes to facilitate gas flow. An adsorption plate 6 for adsorbing harmful chemical gases is placed inside the support frame 5. The specific material of the adsorption plate 6 can be adjusted according to the actual chemical product. A sealing plate 4 with an adhesive sealing gasket is fixedly connected to the side of the support frame 5 to ensure sealing. The gasket design prevents gas leakage inside the mounting box 2. The mounting box 2 is fixedly connected to the side of the mounting plate 9, and the side of the mounting plate 9 is rotatably connected to the drive shaft 11. The side of the mounting plate 9 is also equipped with a drive motor 10 that provides power to the drive shaft 11. The drive motor 10 is designed to adjust the position of the positioning plate 13. One end of the drive shaft 11 is fixedly connected to the linkage plate 12, and the side of the linkage plate 12 is equipped with the fixed end of the electric push rod 8. The electric push rod 8 is designed to ensure that the positioning plate 13 squeezes the sealing plate 4, so that the sealing gasket fits against the mounting box 2. The drive end of the electric push rod 8 passes through the connecting plate and is fixedly connected to the positioning plate 13 that limits the position of the sealing plate 4.

[0026] The processing component 3 includes a connecting pipe 31 that runs through the side of the mounting box 2 and a limiting box 33 installed at the bottom of the connecting pipe 31. The top of the mounting box 2 is provided with an exhaust hole. A piston 34 is slidably connected to the inner side of the connecting pipe 31, and a movable plate 32 that runs through the connecting pipe 31 is fixedly connected to the side of the piston 34. A pressure relief hole is provided on the outer periphery of the connecting pipe 31. One end of the connecting pipe 31 is connected to the reactor body 1. When the piston 34 moves to one end, the pressure relief hole can perform pressure relief operation. A return spring 35 is fixedly connected to the inner side of the limiting box 33. The design of the return spring 35 can drive the piston 34 to return when the pressure decreases. One end of the return spring 35 is fixedly connected to a movable plate 36 that is connected to the inner wall of the limiting box 33. The side of the movable plate 36 is connected and fixedly connected to the movable plate 32.

[0027] The electric actuator 8 and the drive motor 10 are both conventional instruments. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. Both are controlled by remote control switches. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail. The scale of the attached drawings is for reference only and can be adjusted to a certain extent according to the actual use.

[0028] Working principle

[0029] This chemical reactor has a safe and explosion-proof structure. During use, when the pressure inside the reactor body 1 is high or continuously increasing, the gas pressure will enter the connecting pipe 31 and squeeze the piston 34. When the piston 34 is squeezed and moves, it will drive the moving plate 36 at one end of the movable plate 32 to move in conjunction. When the piston 34 moves to a certain position, the pressure relief hole can be used to release the pressure. The gas released during the pressure relief process enters the installation box 2, passes through the adsorption plate 6 for treatment, and is finally discharged. When the adsorption plate 6 needs to be replaced, the electric push rod 8 is started to drive the positioning plate 13 to release the pressure on the sealing plate 4, and the drive motor 10 is started to drive the linkage plate 12 to rotate until it is parallel to the vertical of the installation box 2. Then the sealing plate 4 can be pulled out and the adsorption plate 6 can be replaced.
