Description

Technical Field

[0001] The utility model relates to the technical field of coatings, in particular to a portable superconducting heater. Background Art

[0002] Solvent-free paint and ultra-high solid content paint have high viscosity and poor fluidity. When the temperature is relatively low, the paint in the paint bucket is more difficult to pump out and circulate. Therefore, it is necessary to heat the paint in the paint bucket with a superconducting heater. By heating the paint, the viscosity of the paint is reduced, so that the paint is easier to atomize and the construction performance is improved.

[0003] The superconducting thermal coating heating device disclosed in Chinese patent CN212397177U has high heating power and fast heating speed, and is suitable for high temperature heating. However, while solving the problem, the superconducting thermal coating heating device has the following defects:

[0004] The heating sleeve is located on the outside of the paint bucket and heats the paint inside the paint bucket. This setting makes it take a long time for the paint in the center of the bucket to complete heating, so that the heating efficiency of the device is not very high. The setting of the heating sleeve makes the paint inside the paint bucket unevenly heated as a whole, so that the overall effect of the device in heating the paint is not very good. Utility Model Content

This arrangement prevents the cover plate from rotating on the paint bucket due to the rotation of the first stirring roller. This arrangement allows the stirring roller to better stir and heat the paint.

[0010] Preferably, one side of the support frame is movably connected to a limiting column, one end of the limiting column is fixedly connected to the extrusion plate, and an anti-slip groove is provided on the inner wall of the extrusion plate.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] 1. When heating the paint inside the paint bucket, directly open the sealing cover on the paint bucket, then directly insert the first stirring roller 3 and the second stirring roller 4 into the paint bucket, and at the same time, insert the sealing plug 2 into the barrel mouth of the paint bucket, and then rotate the screw 14 to make the extrusion plate 15 contact with the barrel body, so that the extrusion plate 15 can limit and fix the cover plate 1, and then connect the power cord 12 to the power supply, and turn on the switch on the control box 11, so that the power cord 12 passes through the control box 11, the wire 10 and the conductive slip ring 9 to the inside of the stirring roller.

At this time, the protective sleeve 19 can protect the stirring roller more stably. Then, the device is moved by the handle 21. At the same time, under the protection of the protective sleeve 19, the stirring roller will not be damaged during the movement.
