Abstract

A slip ring device comprises a heat insulation ring sheathed outside the barrel of a rotary kiln and at least one group of slip rings sheathed outside the heat insulation ring; each group of slip rings comprises two slip ring main bodies, wherein one slip ring main body is connected with a positive pole and the other slip ring main body is connected with a negative pole. The slip ring device provided by the invention can effectively avoid the problem of overheated slip rings and larger seam or deformation of the joints of slip rings caused by thermal expansion of the barrel of the rotary kiln.

Description

technical field [0001] The invention relates to a rotary kiln, in particular to a slip ring device. Background technique [0002] A fan that supplies air to the rotary kiln and a thermocouple that detects the temperature inside the rotary kiln are installed on the shell of the rotary kiln for direct reduction. In order to supply power to the fan and output the temperature signal of the thermocouple, a slip ring device is required. to realise. [0003] see figure 1 , which is a structural schematic diagram of an existing thermocouple slip ring device. The existing rotary kiln cylinder body 1a needs about 20 temperature values ​​at different positions, so 20 thermocouples (not shown in the figure) need to be installed at these 20 positions to measure the temperature at the corresponding positions. [0004] Since each thermocouple needs two slip rings 2a (one positive slip ring and one negative slip ring) to collect the temperature signal of the thermocouple, therefore, 40 s...
