Embodiment 1
[0019] The two modes of magnetic transmission are cylindrical radial transmission and disc axial transmission. The structures of the material level controllers of the two transmission modes of the present invention are consistent. As shown in the figure, the material level controller includes a cover 1, a terminal 2, a micro switch 3, a motor assembly 4, an axis A5, and a base 6 , drive assembly I7, spacer flange 8, drive assembly II9, shaft B10, shaft cylinder 11, detection board assembly 12, anti-static assembly 13, cover 1 and base 6 are connected by threads, motor assembly 4 is connected with shaft A5, The shaft A5 is installed on the base 6, the motor assembly 4 is connected to the base 6 through a spring, the micro switch 3 is connected to the motor assembly 4, the cover 1 and the base 6 are provided with a terminal 2, and the drive assembly I7 is connected to the other end of the shaft A5 Connected and fixed, the driving component I7 is isolated by the spacer flange 8 a...
Embodiment 2
[0021] As shown in the figure, the structure of the anti-static type is basically the same as that of the material level controller described in Embodiment 1, the difference is that: the anti-static type is provided with an anti-static component between the shaft cylinder 11 and the spacer flange 8 13. The anti-static component is made of polytetrafluorohexene insulating material and the insulating gasket is insulated from the warehouse wall.

Abstract
High-pressure, high-temperature anti-static resistance rotating material level controller relates to a material level controller, and the material level controller includes the cover, the electrical component, the axis A, the base, the drive component I, the separated set flange, the drive component II, the axis B, the axis cylinder, the detection plate component, and the antistatic component. Its cover connects with the base by thread, the electrical component connecting with the end of the axis A, and the drive component I connecting with the other end of the axis A to be fixed, and the drive component I drives the drive component II after the isolation of the separated set flange, the drive component II connecting with the end of the axis B to be fixed, and the axis cylinder is fixed on the separated set flange through bolt, the other end of the axis B connecting with the detection plate component, and between the axis cylinder and the separated set flange, there is the antistatic component. The invention is suitable for upper and lower threshold alarm of silo or dust clean equipment in the metallurgical, chemical, mining, power, road, food and environmental industries, with the characteristics of resisting high-temperature, high-pressure and antistatic.
Description
technical field [0001] The invention relates to a material level controller, in particular to a high temperature resistant, high pressure and antistatic anti-rotation type material level controller. Background technique [0002] At present, a material level gauge often used in chemical companies is a capacitive level gauge, which is composed of a test electrode, a silo and a material to form a capacitor. Its working principle is: when the material level in the silo changes , its capacitance will change. However, due to frequent changes in the external environment and material status, when the working point of the capacitive level gauge is adjusted, it is prone to drift and cause malfunction. Other existing level gauges are not suitable for high temperature, high pressure, and static electricity. For example, the level gauge used in the dust removal process of blast furnace gas is prone to leakage under high temperature and high pressure; Although the existing pressure-bear...
