[0002] Neopentyl glycol is an organic compound, a colorless and odorless liquid with hydrophilic properties. It is commonly used in the manufacture of solvents, plastics, coatings, lubricants, and many other industrial products. Neopentyl glycol can be produced through the chemical cracking of petroleum or natural gas and is widely used in the manufacture of polyester resins, plasticizers, coatings, detergents, and other chemical products. A heating device for neopentyl glycol production is a piece of equipment used to provide heat during the synthesis of neopentyl glycol. The main function of this device is to heat the reaction raw materials and promote the chemical reaction. It is commonly used in the production reaction process of neopentyl glycol.

[0003] Existing heating devices for neopentyl glycol production typically involve stirring and heating neopentyl glycol within a fixed storage tank, which can lead to uneven heating. If the storage tank could be rotated simultaneously with stirring, the neopentyl glycol could be heated evenly, avoiding uneven heating. Therefore, we propose a heating device for neopentyl glycol production. Utility Model Content

When the rubber plate inside the limiting circular plate contacts the heating cylinder, the rubber plate slides within the limiting groove. At this time, the rubber plate also pushes the connecting rod, causing the connecting rod to push the moving disk. Then, the moving disk drives the four sliding strips to slide along the sliding groove within the protective shell. The spring then tightly presses the rubber plate against the heating cylinder. Through the spring connecting the moving disk and the rubber plate, the sealing between the rubber plate and the heating cylinder is reinforced.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-12 As shown, this utility model is a heating device for neopentyl glycol production, including a base 101 and a first connecting frame 102 and a second connecting frame 103 fixedly connected to the inner wall of the base 101.

The heating mechanism 2 includes a heating cylinder 201 fixedly connected between a first connecting frame 102 and a second connecting frame 103. A motor housing 202 and a motor 203 are fixedly connected to the side of the heating cylinder 201 near the first connecting frame 102. The motor 203 is located inside the motor housing 202. The output shaft of the motor 203 is fixedly connected to a rotating shaft 204 through a coupling. The motor housing 202 provides a certain degree of protection for the motor 203. The motor 203 drives the rotating shaft 204 to rotate, allowing the device to proceed to the next transmission step. One end of the rotating shaft 204 passes through the outer surface of the heating cylinder 201. A first gear 205 is fixedly connected to the outer surface of the rotating shaft 204. The first gear 205 is located inside the heating cylinder 201. Four second gears 206 mesh with the outer surface of the first gear 205. The rotating shaft 204 drives the first gear 205 to rotate.

After that, the connecting plate 208 can drive the liquid storage tank 209 to rotate.

[0021] Two first connecting rings 211 are fixedly connected to the outer surface of the rotating shaft 204. The liquid storage tank 209 has first rotating grooves 212 that match the outer surfaces of the two first connecting rings 211.

The outer surface of the limiting shell 214 is fixedly connected to the inner wall of the heating cylinder 201. The rotating shaft 204 will drive the first connecting rings 211 to rotate in the first rotating grooves 212. At this time, the first connecting rings 211 play a limiting role on the rotating shaft 204 to prevent the rotating shaft 204 from deviating during rotation.

[0022] A third connecting ring 215 is fixedly connected to the outer surface of the rotating shaft 204. A connecting shaft 216 is fixedly connected to the inner wall of each of the four second gears 206. A fourth connecting ring 217 is fixedly connected to the outer surface of the connecting shaft 216. The outer surfaces of the fourth connecting ring 217 and the third connecting ring 215 are rotatably connected to the inner wall of the heating cylinder 201. The second gear 206 will drive the connecting shaft 216 to rotate. Then the connecting shaft 216 will drive the fourth connecting ring 217 to rotate inside the heating cylinder 201. At this time, the fourth connecting ring 217 plays a limiting role on the connecting shaft 216.

[0023] A sealing cap 218 is snapped onto the inner wall of the liquid storage tank 209. Four first bolts 219 are rotatably connected to the inner wall of the sealing cap 218. The outer surfaces of the four first bolts 219 are threaded to the inner wall of the liquid storage tank 209. The first bolts 219 can be tightened into the sealing cap 218 and the liquid storage tank 209, thereby fixing the sealing cap 218 onto the liquid storage tank 209, which facilitates the heating of the device.

[0024] Two connecting arc plates 220 are fixedly connected to the bottom of the heating cylinder 201. Several heating tubes 221 are fixedly connected to the side of the two connecting arc plates 220 that are close to each other. A limiting plate 222 is rotatably connected to the outer surface of the rotating shaft 204. The bottom of the limiting plate 222 is fixedly connected to the inner wall of the base 101. The connecting arc plates 220 fix the position of the heating tubes 221, so that the heating tubes 221 can stably heat the inside of the heating cylinder 201. Then, the limiting plate 222 has a limiting function on the rotating shaft 204.

[0025] The sealing mechanism 3 includes a limiting circular plate 301 disposed on one side of the second connecting frame 103. The limiting circular plate 301 has four rubber plates 302 inside. The limiting circular plate 301 has limiting grooves 303 that match the outer surfaces of the four rubber plates 302. The outer surfaces of the four rubber plates 302 are in contact with one side of the heating cylinder 201. The limiting grooves 303 restrict the movement of the rubber plates 302, so that the rubber plates 302 can only move along the limiting grooves 303, preventing the rubber plates 302 from detaching from the limiting circular plate 301. Two connecting rods 304 are fixedly connected to one side of each of the four rubber plates 302. A movable disk 305 is fixedly connected to one end of each of the two connecting rods 304. Two springs 306 are fixedly connected between the outer surfaces of the four rubber plates 302 and the outer surface of the movable disk 305, respectively. The inner sides of the two springs 306 are respectively sleeved on the outer surfaces of the two connecting rods 304. The connecting rods 304 restrict the springs 306 to prevent them from tilting or shifting during movement, ensuring that the device can transmit power normally. Four sliders 307 are fixedly connected to the outer surface of the movable disk 305. A protective shell 309 is provided on the outer surface of the movable disk 305. The protective shell 309 has grooves 308 inside that match the outer surfaces of the four sliders 307. The outer surface of the protective shell 309 is connected to the limiting... The outer surface of the circular plate 301 is fixedly connected, and the slide groove 308 restricts the movement of the slide bar 307, thereby restricting the movement of the moving disk 305 through the slide bar 307, preventing the moving disk 305 from rotating inside the protective shell 309. The limiting circular plate 301 is provided with a sliding ring 310 inside, and a second rotating groove 311 matching the outer surface of the sliding ring 310 is opened inside the limiting circular plate 301. The outer surface of the sliding ring 310 is slidably connected to the inner wall of the rotating shaft 204. The sliding ring 310 allows the limiting circular plate 301 to both rotate on the rotating shaft 204 and slide on the rotating shaft 204, which facilitates the transmission of the device.

[0026] Two electric actuators 312 are fixedly connected to the inner wall of the base 101. One end of each electric actuator 312 is fixedly connected to a connecting strip 313. The outer surface of each connecting strip 313 is fixedly connected to the outer surface of the limiting circular plate 301. A support strip 314 is fixedly connected to the outer surface of the connecting strip 313. The electric actuators 312 push the connecting strips 313, thereby causing the connecting strips 313 to move the limiting circular plate 301. At the same time, the connecting strips 313 also move the support strip 314. Two limiting rods 315 are slidably connected to the inner wall of the support strip 314. One end of each limiting rod 315 is fixedly connected to the inner wall of the base 101, and the other end of each limiting rod 315 is fixedly connected to the outer surface of the second connecting frame 103. At this time, the support strip 314 slides along the limiting rods 315, and then the limiting rods 315 restrict the movement of the support strip 314, thereby restricting the movement of the limiting circular plate 301.

[0027] Two first connecting blocks 316 are fixedly connected to the outer surface of the protective shell 309, and two second connecting blocks 317 are fixedly connected to the outer surface of the limiting circular plate 301. The inner walls of the two first connecting blocks 316 and the two second connecting blocks 317 are respectively rotatably connected with second bolts 318. The outer surfaces of the second bolts 318 are threaded to the inner wall of the second connecting frame 103. The second bolts 318 can be tightened into the first connecting blocks 316 and the second connecting blocks 317, thereby fixing the protective shell 309 and the limiting circular plate 301 together and preventing the protective shell 309 from moving during the operation of the device.

[0028] One specific application of this embodiment is: When the staff needs to use the equipment, they can unscrew the four first bolts 219 from the sealing cover 218, add neopentyl glycol into the storage tank 209, and then reinstall the sealing cover 218. After that, the two electric actuators 312 can be activated. At this time, the two electric actuators 312 will pull the connecting bar 313. The connecting bar 313 will drive the limiting plate 301 to move. At the same time, the connecting bar 313 will also drive the support bar 314 to slide along the two limiting rods 315. Then the limiting plate 301 will also drive the sliding ring 310 to slide along the rotating shaft 204. When the rubber plate 302 inside the limiting circular plate 301 contacts the heating cylinder 201, the rubber plate 302 will slide in the limiting groove 303. At this time, the rubber plate 302 will also push the connecting rod 304, causing the connecting rod 304 to push the moving disk 305. Then the moving disk 305 will drive the four sliding strips 307 to slide along the sliding groove 308 in the protective shell 309. Then the spring 306 will tightly press the rubber plate 302 against the heating cylinder 201, achieving the effect of reinforcing the seal between the rubber plate 302 and the heating cylinder 201. Then the second bolt 318 can be tightened into the first connecting block 316 and the second connecting block 317. At this time, the second bolt 318 will also be tightened into the second connecting frame 103, thereby fixing the position of the limiting circular plate 301 and the protective shell 309. Then the motor 203 and the heating tube 221 can be started. At this time, several heating tubes 221 will heat the inside of the heating cylinder 201. Then the motor 203 will cause the rotating shaft 204 to rotate. At this time, the limiting plate 222 provides a certain support for the rotating shaft 204. Then, the rotating shaft 204 will drive the first gear 205 to rotate, and the first gear 205 will cause the four second gears 206 to rotate. The four second gears 206 will then drive the gear ring 207 to rotate, so that the gear ring 207 rotates in the opposite direction to the rotating shaft 204. At this time, the gear ring 207 will drive the storage tank 209 to rotate through the connecting plate 208. At the same time, the rotating shaft 204 will also drive the stirring rod 210 to rotate inside the storage tank 209 to stir the neopentyl glycol, achieving the effect of stirring while the storage tank 209 rotates. This allows the neopentyl glycol in the storage tank 209 to be heated evenly. The rotating shaft 204 will drive the third connecting ring 215 to rotate in the heating cylinder 201. At the same time, the second gear 206 will also drive the fourth connecting ring 217 to rotate in the heating cylinder 201 through the connecting shaft 216. Then, the gear ring 207 will drive the second connecting ring 213 to rotate in the limiting shell 214.
