[0031] A rotating shaft 10 is rotatably installed inside the reactor body 1 through a connecting plate 9, and the outer wall of the rotating shaft 10 is connected to the transmission shaft 6 through a rotating mechanism. The rotating mechanism includes a bevel gear 11 fixedly installed on the transmission shaft 6 and the outer wall of the rotating shaft 10, and the two bevel gears 11 are vertically meshed. Two rotating plates 12 are fixedly installed on the outer wall of the rotating shaft 10, and two stirring shafts 13 are rotatably installed between the two rotating plates 12. The outer walls of the two stirring shafts 13 are fixedly installed with a first spur gear 14 that meshes with the gear ring 5, and the outer walls of the two stirring shafts 13 are fixedly installed with a plurality of stirring blades 16 through a mounting sleeve 15. A connecting shaft 18 is rotatably installed on the outer wall of the reactor body 1 through a connecting frame 17, and two connecting blocks 19 are fixedly installed on the outer wall of the connecting shaft 18. The outer walls of the two connecting blocks 19 are fixedly connected to a reactor cover plate 21 through a connecting mechanism. The connecting mechanism includes a connecting rod 20 fixedly installed on the outer wall of the connecting block 19, and the end of the connecting rod 20 is fixedly connected to the upper end surface of the reactor cover plate 21.

[0032] A fixed plate 22 is fixedly installed on the outer wall of the reactor body 1, and a moving block 24 is fixedly connected to the upper end surface of the fixed plate 22 through a telescopic mechanism. The telescopic mechanism includes an electric telescopic rod 23 fixedly installed on the upper end surface of the fixed plate 22. The electric telescopic rod 23 has a large load capacity and a relatively small size, which enables it to be used in equipment of various sizes. It is one of the important telescopic structures of automation equipment, and the electric telescopic rod 23 adopts full hydraulic transmission, which is sensitive and stable in operation, can effectively buffer external impact force, has accurate stroke, and can realize accurate opening and closing of the reactor cover 21. The telescopic end of the electric telescopic rod 23 is fixedly connected to the bottom wall of the moving block 24, and the outer wall of the moving block 24 is fixedly connected to The toothed plate 26 and the outer wall of the movable block 24 are fixedly mounted with two mounting plates 33, and the bottom walls of the two mounting plates 33 are fixedly mounted with stabilizing rods 34, and the two stabilizing rods 34 slide through the fixed plate 22, and the outer wall of the connecting shaft 18 is connected to the toothed plate 26 through a bite mechanism, and the bite mechanism includes a second spur gear 27 fixedly mounted on the outer wall of the connecting shaft 18, and the second spur gear 27 bites with the toothed plate 26, and the bottom wall of the reactor cover 21 is fixedly mounted with a sealing gasket 28, and the sealing gasket 28 is made of vulcanized rubber. Vulcanized rubber refers to vulcanized rubber, which has the characteristics of not being sticky and not easy to break, and also has high elasticity, heat resistance, tensile strength and insolubility in organic solvents, etc. Compared with ordinary rubber, the sealing gasket 28 made of vulcanized rubber is more durable.

[0033] A connecting passage 29 that runs through to the bottom is fixedly installed on the upper end surface of the reactor cover 21, and a gas purification box 30 is fixedly installed on the outer wall of the connecting passage 29. A plurality of gas purification plates 31 are slidably installed on the outer wall of the gas purification box 30 through slots. Each gas purification plate 31 is made of activated carbon. Activated carbon is an adsorption material with a highly developed pore structure and a huge specific surface area. It is usually made of carbonaceous raw materials (such as wood, coal, coconut shells, etc.) through a carbonization and activation process. Its surface contains abundant micropores, mesopores and macropores. These microstructures enable the activated carbon to adsorb a large number of gas molecules, thereby achieving the function of purifying the gas. In addition, the adsorption effect of the activated carbon on odors is relatively stable under different environmental conditions. , it can exert a significant odor adsorption effect without complicated equipment and operating conditions. Its physical adsorption process does not require additional chemical reagents or high-temperature reactions, so it is widely used and easy to operate. Whether in industrial emission treatment equipment, air purifiers, or in home environments, activated carbon can quickly reduce odor concentration and provide users with fresh air. During installation, the outer wall of the gas purification plate 31 fits tightly with the inner wall of the slot, and the irritating gas can be completely absorbed and purified by the gas purification plate 31. The unpurified irritating gas will not leak out. The upper end face of the gas purification box 30 is provided with a plurality of air outlets connected to the interior, and an inverted cone-shaped material guide frame 32 is fixedly installed on the inner wall of the reactor body 1.

[0034] When the present invention is used, all components inside the reactor body 1 are made of thermosetting plastics, and no sparks are generated due to friction during use.

[0035] The specific working steps of this scheme are as follows: the reactor body 1 can be placed firmly through the cooperation of the connecting sleeve 2 and the multiple supporting legs 3, and the electric telescopic rod 23 is initially in a retracted state, at which time the reactor cover 21 is in an open state. When isopentene is produced, the chemical agent can be poured into the reactor body 1 through the cooperation of the upper end surface of the reactor body 1 and the inverted cone-shaped material guide frame 32. The inverted cone-shaped material guide frame 32 can facilitate the pouring of the chemical liquid and prevent part of the chemical liquid from staying on the upper end surface of the gear ring 5 when pouring. Then the electric telescopic rod 23 can be extended upward, and the moving block can be used to move the chemical liquid to the upper end surface of the gear ring 5 during the extension process. The cooperation between the tooth plate 24 and the fixed rod 25 drives the tooth plate 26 to move. At this time, the tooth plate 26 can engage with the second spur gear 27 to drive the connecting shaft 18 to rotate. When the connecting shaft 18 rotates, it can drive the two connecting blocks 19 to rotate. The two connecting blocks 19 then drive the reactor cover plate 21 to rotate together through the cooperation of the connecting rod 20. When the electric telescopic rod 23 is fully extended, the bottom wall of the reactor cover plate 21 and the upper end surface of the reactor body 1 can be parallel, and the bottom wall of the sealing gasket 28 can be driven to fit with the upper end surface of the reactor body 1, thereby covering and sealing the upper end surface of the reactor body 1.

[0036] When the chemical agents are mixed and reacted, the driving motor 8 can drive the transmission shaft 6 to rotate. When the transmission shaft 6 rotates, it can drive the rotating shaft 10 to rotate through two vertically meshed bevel gears 11. The rotating shaft 10 then drives the two stirring shafts 13 to rotate inside the reactor body 1 through two rotating plates 12. At this time, when the stirring shafts 13 are driven to rotate, the two stirring shafts 13 can drive the first spur gears 14 on the same side to engage with the gear ring 5, so that the two first spur gears 14 can respectively drive the stirring shafts 13 on the same side to rotate between the two rotating plates 12, so that the two stirring shafts 13 can respectively drive the multiple stirring blades 16 on the same side to rotate through the cooperation of the mounting sleeves 15. Through the rotation and stirring of the multiple stirring blades 16 on both sides, the chemical agents inside the reactor body 1 can be mixed more evenly, thereby increasing the reaction efficiency.

[0037] During the mixed reaction of various chemical agents, the irritating gas generated can flow into the gas purification box 30 through the connecting channel 29. At this time, the multiple gas purification plates 31 installed in the gas purification box 30 can absorb and purify the irritating gas. The purified gas can be discharged outward through multiple air outlets in the gas purification box 30, thereby preventing the irritating gas from being emitted into the air, thereby avoiding affecting the air quality. When the gas purification plate 31 needs to be replaced, it can be slid out of the slot, and then the new gas purification plate 31 can be reinserted into the slot, thereby ensuring the purification effect of the irritating gas. After the reaction is completed, the isopentene liquid can be discharged from the inside of the reactor body 1 through the discharge pipe 4;

[0038] When the reactor cover 21 needs to be opened, the electric telescopic rod 23 can be retracted downward, at which time the tooth plate 26 can engage the second spur gear 27 to rotate the connecting shaft 18 in the opposite direction, and the connecting shaft 18 drives the reactor cover 21 to rotate and tilt through the cooperation of the connecting block 19 and the connecting rod 20. At this time, the reactor cover 21 can be away from the upper end surface of the reactor body 1, thereby removing the shielding of the reactor cover 21 on the upper end surface of the reactor body 1, thereby realizing the convenient opening of the reactor cover 21, and in the process of extending and retracting the electric telescopic rod 23, the moving block 24 can drive the two stabilizing rods 34 to slide on the upper end surface of the fixed plate 22 through the cooperation of the mounting plate 33, thereby increasing the stability of the electric telescopic rod 23 during extension and retraction, thereby avoiding the displacement of the tooth plate 26 and the inability to normally engage the second spur gear 27.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
