Description

Technical Field

[0001] The utility model relates to the technical field of chemical production, in particular to a protective device for chemical production safety. Background Art

[0002] Chemical industry, that is, chemical industry, is popularized in all aspects of human life. In modern life, chemical products are almost indispensable anytime and anywhere. From material life such as clothing, food, housing, and transportation to spiritual life such as culture, art, and entertainment, chemical products are needed to serve. Some chemical products play an epoch-making and important role in the history of human development. Their production and application even represent a certain historical stage of human civilization. All chemical methods that use chemical methods to change the composition or structure of substances to synthesize new substances belong to chemical production technology, that is, chemical processes. The resulting products are called chemicals or chemical products. In the production process of chemical products, a large amount of waste gas will be generated. The unreasonable treatment of these waste gases will threaten people's health and living environment. Therefore, it is necessary to use protective devices to treat the waste gas from chemical production, so as to protect the health of workers. However, the existing protective devices have a relatively single way of filtering and purifying waste gas during use, and cannot filter and purify waste gas well.

[0003] In order to solve the above technical problems, a Chinese patent with announcement number CN216566323U in the prior art discloses a chemical production safety protection device, including a first box body, a walking wheel is fixedly installed on the bottom of the first box body, a switch is fixedly installed on the outside of the first box body, openings are opened on both sides of the first box body, and filters are fixedly connected to the openings, a submersible pump is fixedly installed on the bottom of the inner side of the first box body, a three-way pipe is fixedly installed on the bottom of the inner side of the first box body through a fixing rod, a water outlet box is symmetrically installed on the top of the inner side of the first box body, and a filtering mechanism is arranged inside the first box body.

After the extrusion plate 14 is away from the two ends of the docking block 13, the pull ring 17 is deflected at a certain angle and hung on the hanging column 18 for temporary positioning. Then, the activated carbon layer 7 and the sponge layer 8 on the inner side of the positioning frame 6 can be pulled out by buckling the pull groove for cleaning or replacement.

The opposite ends of the docking block 13 and the extrusion plate 14 are provided with inclined surfaces 15 that fit each other. A first spring is installed between the two ends of one side of the extrusion plate 14 and the inner wall of the extrusion groove. Then, during installation, the positioning frame 6 and the lap plate 10 can be inserted into the positioning groove and the inner side of the lap groove for engagement. The magnetic strip 11 is adsorbed by the iron strip to complete the initial adsorption and docking. At the same time, the docking block 13 enters the inner side of the docking groove 12, pressing the two groups of extrusion plates 14 to retract again. After the docking block 13 is fully engaged, the two groups of extrusion plates 14 are ejected by the first spring and abut against the two ends of the docking block 13 to complete the assembly.

[0027] In this embodiment, if Figure 1 , Figure 2 and Figure 3 As shown, the extension mechanism includes a fixed cylinder 19 installed on both sides of one end of the top of the base 1, and a movable column 20 is slidably connected to the inner side of the fixed cylinder 19. A plurality of groups of synchronous grooves are arranged on one side of the movable column 20, and reset grooves are provided inside the fixed cylinders 19 on both sides.

Then, the activated carbon layer 7 and the sponge layer 8 on the inner side of the positioning frame 6 can be pulled out for cleaning or replacement by buckling the pull groove. During installation, the positioning frame 6 and the lap plate 10 can be inserted into the positioning groove and the inner side of the lap groove for engagement. The magnetic strip 11 is adsorbed with the iron strip to complete the preliminary adsorption docking. At the same time, the docking block 13 enters the inner side of the docking groove 12, compressing the two sets of extrusion plates 14 to retract again, and the docking block 13 is After 13 is fully inserted, the two sets of extrusion plates 14 are ejected by the first spring and abut against the two ends of the docking block 13 to complete the assembly. The buckle is pulled to drive the connecting plate 23 and the pull rod 22 to move the synchronous block 21 and compress the second spring to retract. After the synchronous block 21 is out of the synchronous groove, the movable column 20 can slide into the fixed cylinder 19 and reset itself. Conversely, when the handrail 5 needs to be raised, it is only necessary to pull the handrail 5 to lift the movable column 20. When the slope 24 of the synchronous groove contacts the slope 24 of the synchronous block 21, the synchronous block 21 can be squeezed and retracted by itself, compressing the second spring to drive the pull rod 22 to move, thereby achieving the effect of raising the height. Holding the handrail 5 and cooperating with multiple sets of universal wheels 25 can drive the entire device to move.
