Description

Technical Field

[0001] The utility model relates to a heating device, in particular to a heating device for PVC raw materials, belonging to the technical field of PVC processing equipment. Background Technique

[0002] Polyvinyl chloride is a polymer formed by vinyl chloride monomer under the action of initiators such as peroxides and azo compounds; or by free radical polymerization reaction mechanism under the action of light and heat. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively called vinyl chloride resins. In the production process of PVC, it is necessary to heat its raw materials. The existing heating devices must wait until the PVC raw materials in the machine body are discharged before new raw materials can be put in, thus wasting time. And basically, the existing raw material processing is carried out by stirring during heating. This method takes a long time to melt the raw materials from the outside to the inside, thus wasting time again.

[0003] Chinese Patent No. CN217072995U provides a raw material heating device for PVC production, which relates to the technical field of PVC production equipment. The following scheme is proposed, including a box body. One side of the top of the box body is provided with a feeding mechanism. A stirring mechanism is installed on the box body. Electric heating plates are installed on the inner walls of the two opposite sides of the box body. Fixing plates are welded to the bottom of the outer walls of the two sides of the box body. Two support rods are symmetrically installed at the bottom ends of the two fixing plates. The bottom ends of the four support rods are connected to a bottom plate. A solenoid valve is installed at the bottom end of the box body. A through hole is opened in the middle of the bottom plate. A screening mechanism is placed on the bottom plate. In the utility model, the raw materials are put in from the feeding hopper. By driving the spiral conveyor rod to rotate by the first servo motor, the raw materials can enter the box body. The electric heating plates are turned on, and the second servo motor drives the rotating rod and the stirring rod to rotate, so as to stir the raw materials and make the raw materials heated evenly, which is more convenient.

[0004] However, although the above case can make the raw materials heated evenly, when adding materials again, it is necessary to wait slowly until the raw materials in the box body are discharged. And by the way of stirring, it can only make the raw materials heated evenly, and cannot make the raw materials melt quickly to a large extent.

[0005] In view of this, the present utility model is specifically proposed. Content of the Utility Model

A stirring rod 206 is fixed on one side of the rotating shaft two 205. The stirring rod 206 can stir the raw material.

[0023] As a technical optimization scheme of the present utility model, the outer shape component 100 includes a box body 101. A partition 102 is fixed inside the box body 101. The partition 102 divides the inside of the box body 101 into two areas. A crushing cavity 103 is arranged inside the box body 101. A heating cavity 104 is arranged inside the box body 101. Support legs 105 are fixed at the bottom of the box body 101. A feeding frame 106 is fixed on one side of the box body 101. The feeding frame 106 facilitates the pouring of the raw material into the box body 101. A discharge pipe 107 is fixed on one side of the box body 101. A heating plate 108 is fixed inside the box body 101. After the heating plate 108 is powered on, it can generate high temperature to melt the crushed raw material.

[0024] As a technical optimization scheme of the present utility model, a material lifting component 300 is fixed on one side of the box body 101. The material lifting component 300 includes a material conveying frame 301. The material conveying frame 301 can pour the raw material in the crushing cavity 103 beside the auger 306. The material conveying frame 301 is fixed on one side of the box body 101. A conveying pipe 302 is fixed at the top of the material conveying frame 301. A discharge frame 303 is fixed on one side of the conveying pipe 302. The discharge frame 303 is fixed on one side of the box body 101. A third motor 304 is fixed at the top of the conveying pipe 302. A rotating shaft three 305 is fixed at the output shaft end of the third motor 304. An auger 306 is fixed on one side of the rotating shaft three 305. The auger 306 cooperates with the conveying pipe 302 to convey the raw material.

[0025] As a technical optimization scheme of the present utility model, a wall scraping component 400 is fixed on the top of the box body 101. The wall scraping component 400 includes an electric telescopic rod 401. The electric telescopic rod 401 is fixed on the top of the box body 101. A connecting block 402 is fixed at the end of the electric telescopic rod 401, which plays a role of transitional connection. A scraping frame 403 is fixed on one side of the connecting block 402.

The sealing ring 404 has a certain elasticity and plays a role of filling the gap between the scraping frame 403 and the inner wall of the box body 101.

[0026] When the utility model is in use, first, raw materials are poured into the crushing chamber 103 inside the box body 101 through the feeding rack 106. Then, the first motor 201 is started, so that the first rotating shaft 202 drives the cutting knife 203 to chop the raw materials. Then, the third motor 304 is started, so that the third rotating shaft 305 drives the auger 306 to rotate, so that the raw materials can enter the heating chamber 104 above the box body 101 through the conveying pipe 302 and the discharging rack 303. Since the first motor 201 is always working, the cutting knife 203 can scrape most of the raw materials at the bottom into the feeding rack 301. After the raw materials enter the heating chamber 104, the heating plate 108 and the second motor 204 are started, so that the heating plate 108 melts the raw materials by the heat emitted, and at the same time, the second motor 204 drives the second rotating shaft 205 to make the stirring rod 206 stir the raw materials, thereby accelerating the melting speed of the raw materials. During the melting process of the raw materials, new raw materials can also be poured into the crushing chamber 103 for preliminary processing. After the raw materials are melted, they are discharged through the discharging pipe 107. After most of them are discharged, the electric telescopic rod 401 is started, so that the scraping rack 403 scrapes the inner wall of the box body 101, so that the raw materials adhered to the inner wall can gather on the partition plate 102, thereby accelerating the discharge of the raw materials.
