Description

Technical Field

[0001] The utility model relates to the technical field of radiation pyrometers, in particular to a cooling device for a radiation pyrometer. Background Art

[0002] Radiation pyrometer is an important key equipment of cold-rolled galvanizing line. The quality of radiation pyrometer determines the quality of galvanized sheet coating. When measuring the temperature of galvanized sheet, it is necessary to maintain a good temperature measurement environment for the pyrometer probe to avoid the decrease of the accuracy of measuring the temperature of galvanized sheet, which will affect the production quality. As the ambient temperature rises in summer, the temperature of cooling water and cooling nitrogen rises, and the hot air blown out of the heating furnace of the treatment tower makes the temperature of the pyrometer probe reach above 65°C, causing the radiation pyrometer to alarm at high temperature, which seriously affects the measurement of sheet temperature. In this case, the quality of galvanized sheet produced is difficult to guarantee.

[0003] In the related art, the temperature of the pyrometer probe is generally improved by improving the cooling device of the radiation pyrometer, increasing the pressure of cooling water and nitrogen, and increasing the flow rate of cooling water and cold air. However, it still exceeds the high temperature alarm temperature of the radiation pyrometer and cannot achieve the ideal cooling effect. In addition, due to the increase in cooling water, the water-cooling jacket is prone to damage, causing the coolant to splash onto the surface of the sheet, affecting the production quality of the galvanized sheet. Utility Model Content

[0004] The purpose of the utility model is to provide a radiation pyrometer cooling device to solve at least one aspect of the problems and defects raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A radiation pyrometer cooling device is arranged in a heat insulation box, comprising a radiation pyrometer body, a pyrometer probe is provided on the top of the radiation pyrometer body, and further comprising:

[0007] a bracket connected to the radiation pyrometer body;

[0008] A blowing port is provided on one side of the heat insulation box;

[0009] A nitrogen pipe is provided through one end of the top of the heat insulation box;

[0010] One end of the nitrogen pipe is connected to a nitrogen output device, and the other end extends to the pyrometer probe;

[0011] A vortex cooling pipe is arranged at the other end of the top of the heat insulation box. One end of the vortex cooling pipe is connected to an air compression pipeline, and the other end extends into the heat insulation box.

[0012] The radiation pyrometer cooling device according to this scheme has at least the following technical effects:

[0013] By setting the radiation pyrometer in the heat insulation box, the heat generated by the treatment tower heating furnace to the radiation pyrometer is isolated, and an air outlet is set on one side of the box body to introduce cold air to enhance the cooling effect inside the heat insulation box; and a nitrogen pipe is set through the top end of the heat insulation box, and nitrogen is delivered to the pyrometer probe through the nitrogen output device to directly cool the probe, thereby improving the working stability of the radiation pyrometer. At the same time, an eddy current cooling pipe is set to deliver cold air to the inside of the heat insulation box and take away the heat inside the heat insulation box, thereby greatly improving the cooling effect. The radiation pyrometer cooling device effectively reduces the temperature of the radiation pyrometer probe, provides a stable measurement environment for the plate temperature of the galvanized sheet, and improves the accuracy of the plate temperature measurement; at the same time, the water cooling sleeve is removed to avoid damage to the water cooling sleeve, which causes the cooling water to splash onto the galvanized sheet surface, thereby ensuring the production quality of the galvanized sheet.

[0014] As a further solution of the utility model: a heat insulation cotton layer is provided on the inner wall of the heat insulation box.

[0015] Because the inner wall of the insulation box is provided with an insulation cotton layer, the insulation cotton layer can effectively reduce the conduction of heat, further isolate the heat generated by the operation of the treatment tower heating furnace from affecting the radiation pyrometer, avoid affecting the radiation pyrometer's measurement of the galvanized sheet temperature, and improve the accuracy of the galvanized sheet temperature measurement.

[0016] As a further solution of the utility model: a peephole is provided on one side of the heat insulation box, and a peep mirror is sealed in the peephole.

[0017] Since a peephole is provided on one side of the thermal insulation box and a peephole is sealed with a peepscope, the operator can observe the temperature distribution and changes inside the thermal insulation box through the peepscope, so as to adjust the intake volume of nitrogen and compressed air in time and avoid the cold air of the thermal insulation box from overflowing from the peephole, so as to ensure that the radiation pyrometer maintains a good temperature detection environment.
