This utility model discloses a pneumatic mixing device for divinylbenzene, specifically relating to the field of chemical engineering. The device includes a mixing mechanism comprising a fixed frame with a support fixedly connected to its bottom. A reaction vessel is fixedly connected to the inner side of the fixed frame, and a top cover is hinged to the top of the reaction vessel. An exhaust pipe and a feed inlet are located on the top of the top cover. The force of a motor-driven short rod, in conjunction with components such as a cross rod, a device sleeve, and a circular plate, drives the short rod to rotate, which in turn drives the cross rod to rotate, which in turn drives the circular plate to rotate.

[0005] Therefore, a divinylbenzene pneumatic mixing device is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a divinylbenzene pneumatic mixing device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a divinylbenzene pneumatic mixing device, comprising a mixing mechanism, the mixing mechanism including a fixed frame, a support fixedly connected to the bottom of the fixed frame, a reaction vessel fixedly connected to the inner side of the fixed frame, a top cover hinged to the top of the reaction vessel, an exhaust pipe provided on the top of the top cover, and a feed inlet provided on the top of the top cover; further comprising a stirring mechanism for fully reacting the gases; and a closing mechanism for closing the feed inlet during stirring; the stirring mechanism includes a circular plate, one side of which is rotatably connected to a rotating rod.

A support 102 is fixedly connected to the bottom of the fixed frame 101. A reaction vessel 103 is fixedly connected to the inner side of the fixed frame 101. A top cover 104 is hinged to the top of the reaction vessel 103. An exhaust pipe 105 is provided on the top of the top cover 104. A feed inlet 106 is provided on the top of the top cover 104.

The stirring mechanism 2 includes a circular plate 205, and a rotating rod 208 is rotatably connected to one side of the circular plate 205.

[0027] Specifically, the exhaust pipe 105 on the top cover 104 can be used to depressurize the inside of the reactor 103 when the reactor 103 stops working, to prevent gas expansion and explosion.

[0028] Example 2

[0029] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 6 As shown below, see details:

[0030] In a preferred embodiment, the stirring mechanism 2 includes a motor 201, which is fixedly connected to the bottom of the reactor 103. A short rod 202 is fixedly connected to the output shaft of the motor 201. One end of the short rod 202 away from the motor 201 passes through the bottom of the reactor 103 and is rotatably connected to the reactor 103. A cross rod 203 is fixedly connected to the other end of the short rod 202 away from the motor 201. A device sleeve 204 is fixedly connected to the bottom of the inner wall of the reactor 103. One end of the cross rod 203 away from the short rod 202 passes through a circular plate 205 and is slidably connected to the circular plate 205. A connecting block 206 is fixedly connected to the circumferential surface of the circular plate 205. A stirring blade 207 is fixedly connected to the other end of the connecting block 206 away from the circular plate 205. A protrusion 209 is fixedly connected to the other end of the device sleeve 204 away from the inner wall of the reactor 103. The above design is beneficial for stirring the gas in the reactor 103, so that the gas inside the reactor 103 can react and mix fully.

[0031] In a preferred embodiment, the protrusion 209 is located on the displacement trajectory of the rotating rod 208, the cross rod 203 is located inside the device sleeve 204, and the protrusion 209 is located between the circular plate 205 and the device sleeve 204. The above design is beneficial to the mutual contact between the protrusion 209 and the rotating rod 208, so that the protrusion 209 lifts the rotating rod 208, thereby causing the rotating rod 208 to drive the circular plate 205 to move vertically.

[0032] In a preferred embodiment, the closing mechanism 3 includes a long rod 301, one end of which is fixedly connected to the end of the cross rod 203 away from the short rod 202. A gear 302 passes through the end of the long rod 301 away from the cross rod 203. A cavity 303 is provided inside the top cover 104. A slider 304 is slidably connected to the inner wall of the cavity 303. A spring 305 is fixedly connected to one end of the slider 304. The end of the spring 305 away from the slider 304 is fixedly connected to the inner wall of the cavity 303. A baffle 309 is fixedly connected to the end of the slider 304 away from the spring 305. A rack A 306 is fixedly connected to the bottom of the slider 304. A rack B 307 is slidably connected to the inner wall of the cavity 303. A magnet 308 is fixedly connected to one side of the rack B 307. Teeth 310 are provided at the bottom of the feed inlet 106. The above design is beneficial to closing the feed inlet 106 when the reactor 103 is working, ensuring the sealing of the device during operation.

[0033] In a preferred embodiment, gear 302 is located on the displacement trajectory of rack A306, rack A306 and gear 302 mesh with each other, and magnetic block 308 is located on the displacement trajectory of baffle 309. The above design is beneficial to drive rack A306 to move horizontally through gear 302, thereby driving slider 304 to move horizontally through rack A306.

[0034] In a preferred embodiment, the rack B307 meshes with the teeth 310, and the magnetic block 308 is magnetically attracted to the baffle 309. The above design is beneficial for limiting the baffle 309 by the magnetic block 308.

[0035] In a preferred embodiment, the number of protrusions 209 is several and they are arranged in a circumferential array on the top of the device sleeve 204, and the number of stirring blades 207 is three and they are arranged in a circumferential array inside the reactor 103. The above design is beneficial to agitate the gas inside the reactor 103 by means of the three stirring blades 207.

[0036] The working process of this utility model is as follows: First, the motor 201 is driven by an external power source, which in turn drives the short rod 202 to rotate via the output shaft. This causes the short rod 202 to rotate the cross rod 203, which in turn drives the circular plate 205 to rotate. The circular plate 205 then drives the rotating rod 208 to rotate in a circular motion, which in turn drives the connecting block 206 to rotate in a circular motion. This, in turn, causes the connecting block 206 to drive the stirring blade 207 to rotate in a circular motion. At this time, the rotating rod 208 will contact the protrusion 209, and... The protrusion 209 lifts the rotating rod 208, causing the rotating rod 208 to drive the circular plate 205 to move vertically. This, in turn, causes the circular plate 205 to drive the connecting block 206 to move vertically, which in turn causes the connecting block 206 to drive the stirring blade 207 to move vertically. This stirs the gas in the reactor 103, making the gas molecules more active and facilitating thorough gas-gas reactions and mixing. When the cross rod 203 rotates, it drives the long rod 301 to rotate, which in turn causes the long rod 301 to move vertically. 1. The gear 302 rotates, causing the rack A306 to move horizontally. The rack A306 then moves the slider 304 horizontally, which in turn moves the baffle 309 horizontally. At this point, the baffle 309 comes into contact with the magnetic block 308. The magnetism of the magnetic block 308 limits the movement of the baffle 309, thus ensuring the sealing of the reactor 103 during operation. When materials need to be added to the reactor 103, the system stops the flow of materials into the reactor 103. The agitation of the feed inlet 106, and the rotation of the feed inlet 106, causes the teeth 310 on the feed inlet 106 to move in a circular motion. This causes the feed inlet 106 to move the rack B307 horizontally via the teeth 310. This causes the rack B307 to move the magnetic block 308 horizontally. At this time, the magnetic block 308 will move away from the baffle 309. Since the baffle 309 is no longer restricted by the magnetic block 308, it will be reset by the reset property of the spring 305. At this time, the baffle 309 will move away from the feed inlet 106, and materials can be added into the reactor 103 through the feed inlet 106.

[0037] The above describes the working principle of the divinylbenzene pneumatic mixing device.
