Problems solved by technology

[0005] Capacitive or radio frequency admittance type, due to the adhesion of materials, the measurement electrode is dirty by the hanging material particles, or due to the different material medium parameters and the superposition effect of the distributed capacitance of the silo structure, additional capacitance is affected, and measurement errors occur. There are often "false" material levels in the reported material level, and sometimes the "zero point" needs to be adjusted frequently on site, which is inconvenient to work
[0006] It is still not very ideal to use these kinds of level gauges to detect the material level of materials

Embodiment 1

[0024] figure 1 It shows the electromagnetic force type material level gauge and the force transmission mode of the electromagnetic force transmission mechanism.

[0025] The electromagnetic force transmission mechanism consists of a coil support 1, a left coil 2, a right coil 3, a left magnet 4, a right magnet 5, a hoop 6, a magnet support 7, a toggle bracket 8, a toggle shaft 12, a detection shaft 15, Supporting shaft 10, bearing 16, electrical switch 11, etc., left coil 2, right coil 3, the two coil through holes at the lower part of coil support 1 are aligned, clamped on the coil support with clamp 6 and screws Fixing, drill holes in the center of left magnet 3 and right magnet 5, fix them on both sides of the magnet bracket with screws, put them into the through holes of left coil 2 and right coil 3, and fix magnet bracket 7 on the toggle bracket with screws On 8 both sides wing arms, toggle support 8 is contained on the axle nose of toggle shaft 12 by supporting axle sl...

Embodiment 2

[0030] When the electromagnetic force transmission mechanism, its coil is a single coil type, and its magnet is a single magnet type, other structural connection modes are the same as example 1.

Embodiment 3

[0032] As the electromagnetic force transmission mechanism, its coil is a multi-coil type, its magnet is a multi-magnet, and other structural connection methods are the same as in Example 1.

Abstract

The invention is related to level sensing device, especially electromagnetic force type level sensing device. The device is mainly composed of electromagnetic force drive gear, toggle axis, detection axis bellows seal piece, appliance switch, and case of meter. Coil and magnet is arranged oppositely. Direct current passes through coil alternately and periodically, so as to generate magnetic field around the coil. Magnetic field of coil and magnetic action force generated from magnetic field of magnet drive the toggle axis together with detection axis to do reciprocal motion to detect materiel. When there is materiel, magnetic force turns appliance switch on/off to send out contact signal of materiel level. The device is applicable to measuring materiel level in bunker of storing materiel with large viscosity under condition of high temperature and high pressure.

Description

Technical field: [0001] The invention belongs to a material level gauge, in particular to an electromagnetic force type material level gauge. Background technique: [0002] In industrial production, many storage bins are required to measure the material level to detect empty or full bins. At present, the commonly used level gauges include rotary type, lever toggle type, tuning fork type, capacitive type, and radio frequency admittance type. [0003] The anti-rotation type and the lever toggle type have a small driving motor inside and a set of gear reduction mechanism to reduce the speed of the output shaft at the end. The deceleration pinion is easy to wear and damage after long-term operation, or the rotor speed of the motor is very high, and the motor Damage, so that the material level gauge can not work normally, and the service life is low. [0004] Due to the adhesion of the material and the temperature change in the silo, the sound difference type material level gaug...
