Description

Technical Field

[0001] This utility model relates to the field of resin particle technology, and in particular to a gas protection device for the production of ABS resin particles. Background Technology

[0002] Inert gases (such as nitrogen and argon) effectively prevent the performance degradation or deterioration of resin raw materials or finished products due to oxidation by replacing oxygen in the reaction system. In high-temperature or precision processing stages, inert gases can form a protective atmosphere, preventing resin particles from contacting air and triggering side reactions. Because of the large amount of inert gas used, the external gas tank needs to be replenished with inert gas regularly. Usually, the production line connected to the gas tank needs to be shut down and can only be operated after the gas is replenished. This process of shutting down and restarting takes a lot of production time and affects processing efficiency. Utility Model Content

[0003] The purpose of this application is to provide a gas protection device for the production of ABS resin granules, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this application provides the following technical solution: A gas protection device for ABS resin particle production includes a main pipe and a protective component installed outside the main pipe. A connecting pipe is fixedly installed at one end of the main pipe. The protective component includes a movable pipe, a connecting pipe, and a mating pipe. The movable pipe is fitted and sleeved on the outside of the connecting pipe. The connecting pipe is fixedly installed on the outer wall of the connecting pipe and communicates with the inside of the connecting pipe. The mating pipe is movably installed inside the connecting pipe. One end of the movable pipe is fitted and sealed to the outer wall of the main pipe. An air inlet is provided on the outer wall of the connecting pipe. The shape of the opening of the mating pipe corresponds to the shape of the opening of the air inlet.

[0005] Preferably, a rotating rod is mounted on the inner wall of the main pipe via bearings, and sealing plates are fixedly mounted on both sides of the rotating rod. Two magnetic blocks are symmetrically mounted on the inner wall of the main pipe. The sealing plates are semi-circular iron metal plates, and the installation positions of the magnetic blocks correspond to the edge positions of the sealing plates. A cylinder is fixedly mounted on the outer wall of the main pipe, and the output end of the cylinder is fixedly connected to the edge of the movable tube. A motor is fixedly mounted on the bottom of the main pipe, and the rotating rod is driven by the motor.

[0006] Preferably, a magnetic tube is fixedly installed at the center of the inner part of the connecting tube. An electromagnetic coil is wound around the outer wall of the magnetic tube, and the electromagnetic coil controls the magnetic attraction force of the magnetic tube through the switching of a circuit. The material of the mating tube is ferrous metal. A sliding groove is formed on the outer wall of the mating tube, and a guide block is fixedly installed on the inner wall of the connecting tube. The sliding groove cooperates with the guide block.

[0011] like Figure 1-4 The gas protection device for ABS resin particle production shown includes a main pipe 1 and a protective component installed outside the main pipe 1. A connecting pipe 2 is fixedly installed at one end of the main pipe 1. The protective component includes a movable pipe 3, a connecting pipe 12, and a mating pipe 4. The movable pipe 3 is fitted and sleeved on the outside of the connecting pipe 2. The connecting pipe 12 is fixedly installed on the outer wall of the connecting pipe 2 and communicates with the inside of the connecting pipe 2. The mating pipe 4 is movably installed inside the connecting pipe 12. One end of the movable pipe 3 is fitted and sealed to the outer wall of the main pipe 1. An air inlet 6 is opened on the outer wall of the connecting pipe 2. The shape of the pipe opening of the mating pipe 4 corresponds to the shape of the opening of the air inlet 6.

[0012] A rotating rod 7 is mounted on the inner wall of the main pipe 1 via bearings. Sealing plates 8 are fixedly mounted on both sides of the rotating rod 7. Two magnetic blocks 9 are symmetrically mounted on the inner wall of the main pipe 1. The sealing plates 8 are semi-circular iron metal plates, and the installation positions of the magnetic blocks 9 correspond to the edge positions of the sealing plates 8. A cylinder 13 is fixedly mounted on the outer wall of the main pipe 1. The output end of the cylinder 13 is fixedly connected to the edge of the movable tube 3. A motor 10 is fixedly mounted at the bottom of the main pipe 1, and the rotating rod 7 is driven by the motor 10.

[0013] A magnetic tube 5 is fixedly installed at the center of the inner part of the connecting pipe 12. An electromagnetic coil is wound around the outer wall of the magnetic tube 5, and the electromagnetic coil controls the magnetic attraction force of the magnetic tube 5 through the on and off of the circuit. The material of the mating pipe 4 is iron metal. A groove 11 is opened on the outer wall of the mating pipe 4, and a guide block is fixedly installed on the inner wall of the connecting pipe 12. The groove 11 cooperates with the guide block.

[0014] Example: An external inert gas tank is equipped with a pressure gauge. If the gas inside the tank is insufficient, the pressure gauge will alarm the control terminal, and cylinder 13 will start, causing the movable tube 3 to slide on the outer wall of the connecting tube 2. In the initial state, the electromagnetic coil is energized, and the magnetic tube 5 is attracted to the mating tube 4 by its magnetic force. After cylinder 13 starts, the electromagnetic coil is de-energized. After cylinder 13 moves the movable tube 3 a certain distance, the mating tube 4 moves into the air inlet 6. The sliding groove 11 on the side of the mating tube 4 slides on the inner wall of the connecting tube 12. Motor 10 drives the rotating rod 7 to rotate, and the sealing plate 8 and the magnetic block 9 adhere and attract each other. The main pipe 1 is closed, and the connecting tube 12 is connected to the external spare gas tank pipeline. Inert gas is introduced into the connecting tube 2, and the gas is introduced into the mixing chamber to continue working. After the external main gas tank is filled with gas, the magnetic tube 5 is energized again. The magnetic force will attract the cooperating tube 4 and separate it from the air inlet 6. The cylinder 13 drives the movable tube 3 to reset. The motor 10 drives the rotating rod 7 to rotate. The sealing plate 8 separates from the magnetic block 9. The main tube 1 continues to work after opening.
