Description

Technical Field

[0001] This utility model relates to the field of chemical production technology, specifically to a protective device for chemical safety production. Background Technology

[0002] In the process of chemical safety production, protective equipment is needed to prevent dust and other contaminants from affecting operators. This requires a protective device to store and collect these tools to prevent them from being contaminated before use.

[0003] According to patent document CN221498915U, this utility model discloses a protective device for chemical safety production, including a support frame. A fixed box is fixedly mounted on the top of the support frame. The fixed box contains a first storage cavity, a second storage cavity, and a third storage cavity arranged sequentially from top to bottom. A partition plate is provided between the first and second storage cavities. A suspension rod is fixedly mounted in the first storage cavity. Sliding grooves are fixedly mounted on the inner walls of the left and right sides of the fixed box, located at the bottom ends of the left and right sides of the second storage cavity. A movable plate slides between the sliding grooves. An inclined platform is located at the top of the movable platform within the second storage cavity. Multiple storage slots are evenly distributed on the top surface of the inclined platform. The advantages of this utility model compared to existing technologies are: the arrangement of the first, second, and third storage cavities allows for the categorized storage of protective equipment according to its type; the second storage cavity provides excellent protection for delicate products such as face shields, making the device more practical.

[0004] While the aforementioned protective equipment for chemical safety production possesses a certain degree of storage and disinfection effects, some toxic gases remain after the gas mask is used. If the protective equipment lacks a purification structure, these harmful gases cannot be discharged and will accumulate inside the box, damaging the protective equipment and endangering the health of personnel using it next time. Furthermore, the sealed doors of the aforementioned protective equipment for chemical safety production lack an opening and closing mechanism, making them prone to automatic opening. This allows dust, particulate matter, and other pollutants from the chemical production environment to easily penetrate into and adhere to the protective equipment, contaminating it and affecting its protective effectiveness.

[0030] Working principle:

[0031] By opening switch structure 3 and placing the protective equipment inside the protective box 1, then starting fan three 2102, fan two 41, and fan one 228, external air enters through the air inlet shell 226. Fan one 228 blows the air into the mounting box 211. Simultaneously, starting fan two 41 draws gas from inside the protective box 1 through connecting pipe one 42 and blows it into the mounting box 211 through connecting pipe two 43. Both external and internal gases undergo layer-by-layer filtration through activated carbon plate 216, air filter plate 217, and molecular sieve 218. Activated carbon plate 216 adsorbs harmful gases from the air, while air filter plate 217 removes dust particles from the air. The gas is intercepted by molecular sieve 218, which selectively adsorbs gas molecules based on their size and polarity, achieving gas separation and purification. The activation of fan 3 2102 blows a portion of the filtered gas into the protective box 1 and onto the protective equipment, further removing toxic and harmful substances from the surface of the equipment and improving disinfection efficiency. At this point, fan 2 41 draws the gas from inside the protective box 1 into the installation box 211 for further filtration, while the remaining filtered gas is discharged through the outlet 2101 into the waste gas collection mechanism 6. Simultaneously, the ultraviolet disinfection lamp is activated to sterilize and disinfect the protective equipment, improving its cleanliness and safety. Other auxiliary structures of fan 3 2102, fan 2 41, and fan 1 228 are existing technologies and will not be described in detail here. When it is necessary to replace the activated carbon plate 216, air filter plate 217, and molecular sieve 218, simply pull the handle 210 to move the fixing plate 219 and the limiting frame 215 forward. The limiting frame 215 drives the guide column 214 to slide forward on the inner wall of the guide groove 213 until the limiting frame 215 is completely moved out of the installation box 211. At this time, the activated carbon plate 216, air filter plate 217, and molecular sieve 218 can be replaced, thereby improving the replacement efficiency and avoiding the problem of a cumbersome and complicated replacement process.

[0032] Pulling the pull plate 35 causes the slide rod 33 to move inside the fixed sleeve 32, thereby causing the trapezoidal block 36 to slide to the left inside the insert frame 37. At this time, the spring 34 is compressed and deformed, and the trapezoidal block 36 disengages from the insert frame 37. Then, the handle 38 can be pulled to open the sealing door 31, and the protective equipment can be placed inside the protective box 1. Then, the sealing door 31 is rotated to close and pressed, so that the inclined surface of the trapezoidal block 36 contacts the outer wall of the insert frame 37, causing the trapezoidal block 36 to be subjected to pressure. The outer wall of the insert frame 37 is squeezed and moved. When the inclined surface of the trapezoidal block 36 passes through the outer wall of the insert frame 37, the trapezoidal block 36 will be driven into the interior of the insert frame 37 under the action of the spring 34, thereby fixing the sealing door 31 and ensuring the tightness of the sealing door 31. This makes the opening and closing of the sealing door 31 more convenient, facilitates the operation of the staff, and improves the efficiency of use. Rollers 5 are provided at the four corners of the bottom of the protective box 1. By setting rollers 5, it is easy to move the protective box 1 and improves the convenience.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
