Problems solved by technology

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-bearing level gauges have certain characteristics of pressure resistance, there are still phenomena of malfunction and missing alarms.

Embodiment 1

[0018] The two transmission methods of magnetic transmission are disc axial transmission and cylindrical radial 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 cover 1 is connected to the base 8 by threads, the motor 7 is fixed on the base 8, and the motor 7 is equipped with a rotating arm 5 and a rotating shaft. Drive the shift fork assembly 4, the switch assembly 3 is fixed on the shift fork assembly 4, the shift fork assembly 4 is connected with one end of the shaft 6 through threads and drives the drive assembly I9, the other end of the shaft 6 is connected with the drive assembly I9 through threads and fixed on the On the flange 10, the terminal assembly 2 is installed on the base 8, the driving assembly I9 is ​​separated by the spacer 11 and drives the driving assembly II12, the driving assembly II12 is installed on the shaft cylinder assembly 13, and the driv...

Embodiment 2

[0020] As shown in the figure, the structure of the antistatic type is basically the same as that of the material level controller described in Embodiment 1, the difference being that: the antistatic type adds an antistatic component 16 between the shaft cylinder component 13 and the flange 10 . The anti-static components are made of polytetrafluoroethylene insulating material and the insulating gasket is insulated from the warehouse wall.

Abstract

The high-temperature high-pressure static-proof swing material position controller made from magnetic material comprises: a cover connected with a base by thread, a motor fixed on base, a fork assembly connected with one end of the shaft, a drive assembly I connected with one end of the shaft to drive a drive assembly II arranged on shaft cylinder assembly, the flange, an isolation sleeve, a checkup shaft / board, and a static-proof assembly between the cylinder assembly and flange. This invention has wide application.

Description

technical field [0001] The invention relates to a material level controller, in particular to a high temperature resistant, high pressure and antistatic swing 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-bearing type...
