Description

Technical Field

[0001] The utility model relates to the technical field of safety instruments, in particular to a chemical polymerization kettle with safety instruments. Background Art

[0002] Chemical polymerization kettle is a kind of equipment used in chemical processes such as chemical reaction, polymerization and mixing. It is usually made of special corrosion-resistant materials, such as stainless steel, titanium alloy or fiberglass. The polymerization kettle usually has a sealed design to ensure that no leakage occurs when handling hazardous substances. Chemical polymerization kettle is generally a vertical cylindrical autoclave with a jacket to allow steam or cold water to be introduced for heating or cooling. Safety instruments are commonly used components of chemical polymerization kettles and are generally used to read the temperature and air pressure inside the chemical polymerization kettle.

[0003] There are also some problems with the common safety instruments used in chemical polymerization kettles. This is because most of the traditional safety instruments used in chemical polymerization kettles protect the inside of the instrument through an instrument cover, which has a simple structure. If the instrument cover is damaged, it is inconvenient to replace the instrument cover, which affects the normal use of the device. At the same time, the instrument valves of traditional chemical polymerization kettle safety instruments are mostly exposed on the outer surface, which are easily corroded by the air, rusted or accidentally touched, increasing the safety hazard during the next use. For this reason, we propose a chemical polymerization kettle with a safety instrument to solve the above problems. Utility Model Content

[0029] A replacement mechanism 3 is provided above the protection mechanism 2. The replacement mechanism 3 is used for quickly replacing the instrument surface cover. The replacement mechanism 3 includes an instrument panel 31, and grooves are provided on both sides of the inner wall of the instrument panel 31. Push rods 34 are provided on both sides of the groove of the instrument panel 31, and the push rods 34 penetrate the instrument panel 31 and extend to the inside of the instrument panel 31, and a first slide groove 35 is provided on the inner wall of the instrument panel 31 on the outer surface of the push rod 34. A fixed frame 32 is provided inside the instrument panel 31, and protrusions are provided on both sides of the fixed frame 32, and a protective cover 33 is fixedly connected to the inside of the fixed frame 32. A placement groove is provided inside the protrusions on both sides of the fixed frame 32, and a limiting block 36 is provided inside the placement groove, and a second return spring 37 is fixedly connected between the limiting block 36 and the inner wall of the placement groove, and the placement groove is connected to the first slide groove 35. According to the attached Figure 6 By setting the limit block 36 and the second return spring 37, when the fixed frame 32 is engaged with the inside of the instrument panel 31, the second return spring 37 will push the limit block 36 into the first slide groove 35 to complete the fixation of the fixed frame 32. At the same time, the push rod 34 can be pushed to withdraw the limit block 36 from the first slide groove 35, release the fixation of the fixed frame 32, and achieve the purpose of quickly replacing the protective cover 33, thereby improving work efficiency.

[0030] The outer surfaces of the protrusions on both sides of the fixed frame 32 are provided with second slide grooves 38, and the inner part of the second slide grooves 38 is slidably connected with a push block 39, and the push block 39 is fixedly connected to the outer surface of the limit block 36. Figure 8 By setting the second slide groove 38 and the pushing block 39, the pushing block 39 can pull the limit block 36 to move, thereby facilitating the fixing frame 32 to be engaged with the inner wall of the instrument panel 31, facilitating the replacement of the instrument panel 31, and facilitating the use of the device.

[0031] Working principle: When using the device, the polymerization kettle body 1 needs to be placed in a suitable position first, and then the pulling rod 242 is pulled, so that the pulling rod 242 drives the two groups of L-shaped blocks 241 and the limiting rod 243 to move toward the first return spring 244, thereby releasing the limiting position of the limiting rod 243 on the block 26, and rotating the hinge block 25 to withdraw the block 26 from the inside of the slot 23, and finally rotating and opening the instrument valve body 21 on one side of the fixed block 22, so that the polymerization kettle body can be observed through the instrument panel 31 1. After the observation is completed, the instrument valve body 21 is closed, and the hinge block 25 is rotated again, so that the hinge block 25 drives the block 26 to enter the slot 23, so that the block 26 pushes one end of the triangular body of the limiting rod 243 to move toward the first return spring 244. When the block 26 completely enters the slot 23, the limiting rod 243 will move toward the block 26 under the action of the elastic force of the first return spring 244, and finally the block 26 is limited, ensuring the stability of the hinge block 25.

[0032] Then, if the protective cover 33 needs to be replaced, the push rod 34 can be pushed so that the push rod 34 pushes the limit block 36 to exit the first slide groove 35, thereby releasing the fixation of the fixed frame 32, and the fixed frame 32 can be removed for replacement. Then, when replacing the fixed frame 32, it is necessary to press the push block 39 first so that the push block 39 moves along the second slide groove 38. At the same time, the push block 39 will drive the limit block 36 to move toward the second return spring 37, causing the second return spring 37 to deform. Then, the protrusions on both sides of the fixed frame 32 are engaged with the grooves on both sides of the inner wall of the instrument panel 31, and the push block 39 can be released. At this time, the limit block 36 will enter the first slide groove 35 under the action of the elastic force of the second return spring 37 itself, completing the fixation of the fixed frame 32. The subsequent reset action is the same as above. The above is the entire working principle of the present utility model.
