Problems solved by technology

[0005] Since the rotary kiln shell 1a may be displaced along the axial direction of the rotary kiln shell 1a during the rotation process, and because the brush 3a is fixed on the workbench through the support beam, it is impossible to ensure that the slip ring 2a and the brush 3a Real-time contact, thus unable to provide a stable power supply to the fan or transmit a stable thermocouple electrical signal

Abstract

The invention provides a slip ring power supply device. The slip ring power supply device comprises an electrical brush used for fixing a mobile mechanism arranged on the electrical brush and a limitation mechanism used for positioning the mobile mechanism, wherein the limitation mechanism is fixed on a cylinder body of a rotary kiln; and the mobile mechanism is placed on a worktable, and can be driven to move on the worktable along the direction parallel to the axial line of the cylinder body of the rotary kiln through the limitation mechanism. The slip ring power supply device provided by the invention is used for ensuring the real-time contact between the slip ring and the electrical brush, and supplying power to a blower fan arranged on the rotary kiln or supplying stable electric signal to a thermocouple.

Description

technical field [0001] The invention relates to a rotary kiln, in particular to a slip ring power supply 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 slip ring device. A power supply or temperature measurement slip ring 2a is installed on the cylinder body 1a of the existing rotary kiln, which is used to supply power to the fan or transmit the temperature signal of the thermocouple. [0004] The slip ring 2a is a circular ring structure, which is set outside the cylinder body 1a of the rotary kiln, and then fixed by several or dozens of supports (not shown in the figure). The slip ring 2a ...
