Description

Technical Field

[0001] The utility model relates to the technical field of ultraviolet absorber production, in particular to a heating device for ultraviolet absorber production. Background Art

[0002] UV absorbers are a class of substances that can absorb ultraviolet rays and convert them into harmless energy. They are widely used as light stabilizers to protect polymer materials, textiles and other products from damage by ultraviolet rays. UV absorbers need to be dried and heated during the production process, so a heating device is required.

[0003] After searching, the patent publication number CN220017701U discloses a heating device for ultraviolet absorber production, which relates to the technical field of ultraviolet absorber production. In order to solve the problem that the existing heating equipment adopts the drying method to heat up, which easily leads to uneven heat of the accumulated ultraviolet absorber, and uses a stirring rod to turn it over, which easily leads to dead corners inside, resulting in uneven heating of the ultraviolet absorber raw materials. It includes: a heating box, the front end of the heating box is movably equipped with a box door through a hinge; it also includes: a first motor, which is installed on the outer wall of one side of the heating box through screws, the output end of the first motor is provided with a transmission shaft, one end of the transmission shaft is provided with a rotating table, and a driven table is installed on the inner wall of one side of the heating box; a hollow water cylinder, which is installed between the rotating table and the driven table, the outer walls of the upper and lower ends of the hollow water cylinder are provided with water inlet and outlet plugs, and both sides of the inner wall of the hollow water cylinder are provided with electric heaters.

[0004] However, this patent still has some shortcomings. In actual use, this patent mainly heats the raw material by transferring heat from hot water outside the raw material heating barrel. This heating method requires the heat to be gradually transferred inward, which makes the heating efficiency of the ultraviolet absorber low. In addition, since the second motor is arranged inside the raw material heating barrel, the second motor needs to work in a high temperature environment for a long time and cannot dissipate heat, which can easily cause damage to the second motor and shorten its service life.

[0005] In order to solve the above problems, we propose a heating device for producing ultraviolet absorbers. Utility Model Content
