Description

Technical Field

[0001] This utility model relates to the field of chemical engineering technology, and more specifically, it relates to a safety protection device for chemical engineering. Background Technology

[0002] Currently, feeding is a crucial step in the chemical industry, involving the addition of various chemical raw materials and reactants. However, this process is often accompanied by safety hazards, such as material leakage, airborne particles, improper addition of reactants, and falls. These not only affect production efficiency but may also threaten the health of operators. To address these issues, chemical engineering feeding safety protection devices have emerged.

[0003] A search revealed that Chinese utility model patent application number CN202323019157.2 discloses a safety protection device for feeding materials in chemical engineering, including a feed hopper, a safety filter, and a sealing cover. An installation block is welded inside the feed hopper. The bottom of the safety filter is fixedly connected to four circumferentially distributed positioning blocks by screws. A slider and two symmetrically arranged limiting blocks are slidably assembled inside the positioning blocks. One end of the limiting blocks is inclined. A connecting block is fixedly connected to one side of each of the two limiting blocks by screws. A sliding rod is fixedly nested on each of the two connecting blocks.

[0004] To use, grasp the handle to open the sealing cover, align the positioning block with the installation groove and insert it until the limiting block is ejected into the limiting groove by the first spring and fixed. Then, randomly feed the material through the safety filter. After feeding, close the sealing cover. When the safety filter is damaged or clogged and needs to be disassembled, pull the pull block. The pull block moves the pull rod, which moves the slider, which moves the two slide rods. The two slide rods move the two limiting blocks away from the limiting groove. At this point, the safety filter can be removed. Then, replace it with a new filter or install the cleaned filter. This achieves quick disassembly and assembly. This device prevents personnel from accidentally falling into the feed hopper during the feeding process, thus avoiding safety hazards. At the same time, the safety filter can control the speed of material entry, which facilitates subsequent processing. It should be noted that the feed hopper is installed on the processing device.

[0005] When replacing the safety filter, because it is installed inside the feed hopper, it is inconvenient for people to remove it from the hopper. In addition, since people remove the safety filter by hand, it may tilt during the process, causing impurities on the filter to slide down and fall into the inside and around the feed hopper. Furthermore, during the material feeding process, impurities will accumulate on the top of the safety filter, and a large amount of impurities will clog the safety filter, affecting the flow of chemical materials through the mesh of the safety filter and reducing feeding efficiency.

[0031] Please see Figures 1-5A safety protection device for chemical engineering includes a feed hopper 1 and a safety filter 2. A protective cover 3 is detachably installed on the top of the feed hopper 1. The protective cover 3 is connected to the feed hopper 1 by multiple latches 19, facilitating its assembly and disassembly. Multiple second limiting grooves 17 are evenly arranged on the top of the feed hopper 1. Multiple limiting posts 18 are evenly fixedly connected to the bottom of the protective cover 3, and these posts 18 are inserted into the interiors of the second limiting grooves 17 to limit the movement of the protective cover 3. Multiple lifting rings 13 are evenly fixedly connected to the top of the protective cover 3 to facilitate lifting. A sealing gasket 14 is provided at the bottom of the protective cover 3 to ensure a tight seal between the protective cover 3 and the feed hopper 1. A feeding pipe 4 is connected to the top of the protective cover 3, and a sealing cap 5 is threadedly connected to the top of the feeding pipe 4. A fixing cylinder 6 is inserted inside the feed hopper 1, and the inner diameter of the fixing cylinder 6 is the same as the inner diameter of the protective cover 3. Equally, multiple first limiting grooves 15 are evenly arranged on the upper side of the inside of the feed hopper 1. Multiple limiting blocks 16 are fixedly connected to the outer wall of the fixed cylinder 6. The multiple limiting blocks 16 are respectively inserted into the inside of the multiple first limiting grooves 15 to limit the fixed cylinder 6. The safety filter screen 2 is installed on the bottom side of the inside of the fixed cylinder 6. A top ring 7 is arranged inside the feed hopper 1 below the fixed cylinder 6. Multiple connecting rods 8 are fixedly connected to the bottom end of the top ring 7. The multiple connecting rods 8 are all in a sealing sliding fit with the feed hopper 1. Multiple circular grooves 20 are arranged on the feed hopper 1. The multiple connecting rods 8 are respectively in a sliding fit with the multiple circular grooves 20. Each of the multiple circular grooves 20 is provided with an annular groove 21. Each of the multiple annular grooves 21 is provided with a sealing ring 22. The sealing ring 22 is in a sealing sliding fit with the connecting rod 8 to ensure the sealing between the connecting rod 8 and the feed hopper 1. Lifting rings 9 are fixedly connected to the bottom end of the multiple connecting rods 8.

[0032] Specifically, by holding the lifting ring 9, people can push multiple connecting rods 8 and the top ring 7 upwards. The top ring 7 pushes the fixed cylinder 6 and the safety filter 2 to the upper side of the feed hopper 1, making it easier for people to remove the fixed cylinder 6 and the safety filter 2 from the inside of the feed hopper 1. This facilitates the disassembly of the safety filter 2 and improves its practicality. Since the impurities filtered out by the safety filter 2 will accumulate inside the fixed cylinder 6, the process of removing the fixed cylinder 6 and the safety filter 2 from the inside of the feed hopper 1 can prevent impurities from slipping off the safety filter 2 and falling around and inside the feed hopper 1.

[0033] Please see Figure 1 and Figure 5 A rotating shaft 10 is rotatably connected to the protective cover 3. A stirring plate 11 is fixedly connected to the bottom end of the rotating shaft 10. A motor 12 is installed on the protective cover 3. The output end of the motor 12 is fixedly connected to the top end of the rotating shaft 10, which facilitates the stirring of the material on the safety filter 2 and facilitates the smooth flow of the material from the mesh of the safety filter 2.

[0034] Specifically, the motor 12 drives the rotating shaft 10 and the stirring plate 11 to rotate. The stirring plate 11 stirs the material on the safety filter 2, which facilitates the removal of impurities from the safety filter 2 and prevents it from becoming clogged. At the same time, the stirring process facilitates the material falling through the mesh of the safety filter 2, improving the efficiency of material falling.

[0035] In summary, when using the overall equipment:

[0036] Insert the fixed cylinder 6 into the inside of the feed hopper 1, and insert multiple limiting blocks 16 into the inside of multiple first limiting grooves 15 respectively. Then cover the upper side of the feed hopper 1 with the protective cover 3, and insert multiple limiting posts 18 into the inside of multiple second limiting grooves 17 respectively. Then fix the protective cover 3 with multiple latches 19. At this time, the sealing gasket 14 is pressed on the upper side of the fixed cylinder 6 and the feed hopper 1. Then unscrew the sealing cover 5. Then add the material into the inside of the protective cover 3 and the fixed cylinder 6 through the feeding pipe 4. After the material is added, screw the sealing cover 5 onto the feeding pipe. Then start the motor 12. The motor 12 drives the rotating shaft 10 and the stirring plate 11 to rotate. The stirring plate 11 stirs the material on the safety filter 2. The material on the safety filter 2 falls through the mesh of the safety filter 2 and falls into the corresponding chemical equipment through the feed hopper 1.

[0037] When the safety filter 2 needs to be replaced, the protective cover 3 is removed. Then, people lift the lifting ring 9 by hand and push the multiple connecting rods 8 and the top ring 7 upwards. The top ring 7 pushes the fixing cylinder 6 and the safety filter 2 to the upper side of the feed hopper 1. At the same time, another worker removes the fixing cylinder 6 and the safety filter 2.
