Description

Technical Field

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

[0002] Chemical engineering utilizes chemical principles and technologies to transform raw materials into economically valuable chemical products. A chemical process refers to the processes conducted in the chemical industry, including raw material preparation, reaction, separation, purification, and product processing, to produce the desired chemical substances or products. This process necessitates a strong focus on chemical safety to ensure that personnel, equipment, and the environment are protected from the hazards and risks that chemicals and chemical processes may cause. Chemical safety primarily aims to prevent accidents and reduce potential risks to protect human life and health, while ensuring environmental protection from pollution. Chemical isolation devices are used in the chemical industry to isolate and protect operators, equipment, and the environment, preventing the leakage of hazardous substances and ensuring operator safety.

[0003] For example, utility model patent CN221256346U discloses a chemical safety isolation device, including an isolation frame. An isolation frame is fixedly connected to one side of the isolation frame, and a positioning plate is fixedly connected to the inner bottom wall of the isolation frame. A positioning hole is opened on the front of the positioning plate, and a positioning rod is movably connected to the inner wall of the positioning hole. An isolation net frame is fixedly connected to the front of the positioning rod, and an isolation net body is fixedly connected to the inner wall of the isolation net frame. This chemical safety isolation device, through its isolation frame, isolation net frame, isolation net body, isolation frame, mounting plate, positioning rod, limiting pad, positioning hole, and positioning plate, allows for direct replacement of damaged isolation nets during the isolation of chemical production equipment, eliminating the need to replace the entire isolation device, thus reducing operating costs and facilitating use. However, it suffers from a slow replacement rate when replacing damaged isolation nets, resulting in prolonged replacement time and ultimately reducing replacement efficiency. Therefore, we propose a chemical safety isolation device. Utility Model Content

[0004] The purpose of this invention is to provide an isolation device for chemical safety, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a chemical safety isolation device, comprising an isolation frame, a left column, and a right column. The upper end of the isolation frame has a second slot, which is connected to a placement groove on the isolation frame. The placement groove is connected to a first slot on the isolation frame. An isolation net body is inserted into the inner wall of the placement groove. Locking holes are provided on both sides of the top of the isolation net body. A top locking assembly for the isolation net is provided at the upper front end of the isolation frame. The top locking assembly includes two symmetrically arranged locking posts. An L-shaped flip plate is fixedly connected to the upper end of each locking post. A rotating shaft is fixedly connected to the lower left side of the L-shaped flip plate. A first side plate is rotatably connected to the left side of the rotating shaft via a bearing, and the inner end of the first side plate is fixedly connected to the isolation frame. A second side plate is rotatably connected to the outer end of the rotating shaft via a bearing, and the inner end of the second side plate is fixedly connected to the isolation frame.

[0007] Preferably, a blocking plate is fixedly connected to the end of the rack away from the electric push rod, and the height of the blocking plate is greater than the height of the rack.

[0008] Preferably, the first slot is located on the lower side of the placement slot, and the second slot is located on the upper side of the placement slot.

[0009] Preferably, a left column is fixedly connected to the left end of the isolation frame, and a plurality of vertically distributed fixed columns are fixedly connected to the left end of the left column. Each fixed column has an insertion hole at its upper end. A right column is fixedly connected to the right end of the isolation frame, and a plurality of vertically distributed L-shaped plates are fixedly connected to the right end of the right column.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. Equipped with an isolation frame, placement slot, first slot, second slot, isolation net body, top locking assembly of the isolation net, left column, and right column, this device allows for replacement of a damaged isolation net body. An external power source powers the electric push rod, which in turn drives a rack to move inward. The rack then drives a gear to rotate counter-clockwise, which in turn drives a rotating shaft to rotate counter-clockwise. This rotating shaft then drives an L-shaped flip plate and locking column to rotate counter-clockwise, disengaging the locking column from the locking hole. The damaged isolation net body can then be removed from the placement slot. After removing the damaged mesh from the slot, the new mesh body is reinserted into the slot. The electric push rod is then controlled externally. The output of the electric push rod drives the rack to move outwards, which in turn drives the gear to rotate clockwise, causing the rotating shaft to rotate clockwise. This rotating shaft then drives the L-shaped flip plate and locking pin to rotate clockwise. Once the locking pin engages in the locking hole, the power supply to the electric push rod is disconnected. This invention allows for convenient removal and replacement of damaged mesh bodies, improving the efficiency and ease of mesh body replacement.

[0014] 2. Equipped with a left side column, a right side column, a fixed column, a socket, an L-shaped plate, a tapered column, and a locking hole, it allows for the alignment of the socket on the right side column of the left device with the fixed column on the left side column of the right device. Then, the socket is inserted into the socket. This enables the extension and splicing of the isolation net, and also allows for the angle adjustment of the spliced ​​device, thus improving its applicability. Attached Figure Description

[0035] Working principle: When it is necessary to replace the damaged isolation net body 5, the electric push rod 68 can be powered by an external power source. The output end of the electric push rod 68 drives the rack 67 to move inward. The rack 67 drives the gear 66 to rotate counterclockwise, which in turn drives the rotating shaft 63 to rotate counterclockwise. The rotating shaft 63 drives the L-shaped flip plate 61 and the locking pin 62 to rotate counterclockwise. At this time, the locking pin 62 disengages from the locking hole 14. Then the damaged isolation net body 5 can be removed from the placement slot 2. Next, the new isolation net body 5 is reinserted into the placement slot. 2. Next, the electric push rod 68 is controlled by external control. At this time, the output end of the electric push rod 68 drives the rack 67 to move outward. The rack 67 drives the gear 66 to rotate clockwise, which in turn drives the rotating shaft 63 to rotate clockwise. The rotating shaft 63 drives the L-shaped flip plate 61 and the locking pin 62 to rotate clockwise. When the locking pin 62 is engaged in the locking hole 14, the power supply to the electric push rod 68 can be disconnected. This utility model realizes the convenient removal and replacement of the damaged isolation net body 5, improving the replacement efficiency and ease of the isolation net body 5.
