Description

Technical Field

[0001] The utility model belongs to the field of rubber processing, and in particular relates to a rubber raw material heating device. Background Art

[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is highly elastic at room temperature and can deform significantly under minimal external force, returning to its original shape upon removal. Early rubber was derived from the latex of plants such as rubber trees and rubber grass, processed into a material that is elastic, insulating, and impermeable to water and air. Rubber is widely used as an insulating material in cables. This process requires heating and melting the raw material to make it fluid. This melting process requires specialized heating equipment, which is then used for further processing.

[0003] The current rubber raw material heating equipment can meet basic usage requirements, but there are still some deficiencies and technical defects in actual use. For example, a rubber raw material melting and processing device disclosed in announcement number CN207838946U can effectively melt the rubber, but the raw material cannot be dried before heating and melting. The moisture content in the raw material is too high, and gas will be generated when heated, affecting the quality of the finished product. At the same time, if some small metal objects contained in the rubber raw material particles are not cleaned out in time, they will damage the equipment and affect the product quality. In addition, during the melting process, the rubber easily adheres to the inner wall of the device, and the device cannot clean the inner wall of the device in time, resulting in waste of raw materials.

[0004] Therefore, the above problems are issues that should be considered and solved in the process of rubber production. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to deepen the understanding of the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and embodiments. The embodiments are only used to explain the present invention and do not limit the scope of protection.

[0021] This embodiment provides a rubber raw material heating device, comprising a feed box 1 and a heating box 2 connected to each other, wherein heating elements are provided in both the feed box 1 and the heating box 2.

The sides of the magnetic filter 3 are provided with raised rails 5 adapted to the chutes 4. A lifting rod 6 is provided in the middle of the magnetic filter 3 to facilitate filter replacement. A plurality of guide plates 7 are provided below the magnetic filter 3, arranged in an oblique and staggered manner. The heating elements include heating plates 8 provided on the inner walls of the feed box 1 and the heating box 1, and heating wires 9 provided inside the guide plates 7.

[0022] The heating box 2 includes an outer shell 10 and an inner shell 11. A shock-absorbing mechanism is provided between the outer shell 10 and the inner shell 11. The shock-absorbing mechanism is a buffer pad 12. The buffer pad 12 is arc-shaped and filled with honeycomb butyl rubber particles. A stirring mechanism is provided inside the inner tank 11, and the stirring mechanism includes a stirring frame, which includes a main shaft 13 and a mixing frame 14 arranged around the outer periphery of the main shaft 13, and a plurality of stirring rods 15 are evenly arranged on the mixing frame 14. The main shaft 13 is also provided with a scraper 16 adapted to the shape of the inner wall of the heating box 2, and a driving motor 17 for driving the main shaft 13 to rotate is provided on the top of the heating box 2, and a discharge port 18 is provided at the bottom of the heating box 2, and a valve is provided at the discharge port 18. A supporting mechanism is also provided at the bottom of the heating box 2, and the supporting mechanism includes a plurality of supporting legs 19 arranged at the bottom of the heating box 2, and a base 20 is provided at the bottom of the supporting legs 19, and a shock-absorbing pad 21 is provided at the bottom of the base 20 to buffer the vibration generated during the operation of the buffer equipment, so that the operation of the equipment is more stable. The inner walls of the feed box 1 and the inner liner 11 are both provided with a polytetrafluoroethylene coating layer 22, so that the inner walls of the feed box 1 and the inner liner 11 are smooth, forming an inner wall structure similar to a non-stick pan, effectively preventing rubber from sticking to the inner wall. The inner wall of the outer shell 10 is also provided with an insulating asbestos layer 23, which reduces heat loss and saves energy.

[0023] The present embodiment provides a rubber raw material heating device, in which the rubber raw material enters from the feed box 1 and first passes through the provided magnetic filter 3, so that before heating, the rubber raw material particles can be filtered out under the magnetic adsorption of the magnetic filter 3 to remove the possible metal small objects contained in the rubber raw material particles, thereby improving the purity of the raw material. Then the raw material slides evenly from the guide plate 7, so that the rubber raw material particles are dried in the process of sliding from the guide plate, thereby avoiding the situation where the raw material produces a large amount of gas due to its own high moisture content during the heating process of the heating box 2. Then the raw material enters the heating box 2 for heating, and the heated and melted raw materials are mixed by the mixing rack 14 in cooperation with the stirring rod 15, so that the distribution of the rubber raw material components is more uniform. When the main shaft 13 rotates, the scraper 16 is driven to rotate synchronously, and the scraper 16 is used to scrape off the rubber raw material adhered to the inner wall of the heating box 2 to ensure the cleanliness of the inside of the heating tank. Then the raw material is discharged from the discharge port.
