Carbon powder canister material level meter

Abstract

The invention provides a slack coal tank material level meter which is arranged on a slack coal tank and comprises a wiring box, a connecting pipe which is connected with the wiring box, a flange which is arranged above an opening of the slack coal tank, a first lock latch, a second lock latch and a probe. The connecting pipe extends into the slack coal tank and comprises a conductive wire pipe and an insulation wire pipe which is sheathed on the periphery of the conductive wire pipe; the connecting pipe is provided with a first end and a second end which face to each other; the first lock latch is arranged between the connecting pipe and the flange; the probe is connected with the tail end of the second end of the connecting pipe by the second lock latch and a second lock latch connecting nut. The slack coal tank material level meter with the design can exactly measure the distribution situation of carbon black inside the slack coal tank, has simple and compact structure, overcomes the bad result which is caused by the adsorption and corrosion of the carbon black material in the prior art, and improves the production efficiency of the carbon black.

Description

technical field [0001] The invention relates to a material level gauge, in particular to a material level gauge for measuring the distribution position of carbon black materials in a powdered charcoal tank. Background technique [0002] In the carbon black industry, the material level gauge is mainly used to measure and indicate the changes in the distribution of carbon black material height and level in the powder carbon tank. After the measuring probe of the instrument level meter touches the carbon black material, according to the principle of carbon black conductivity, the different resistance value signals of the carbon black material at different heights are transmitted to the controller in the form of a switch to indicate the current state of the carbon black material. The specific height is then transmitted to the pipeline valve by the controller to decide whether to add material to the powder charcoal tank. However, in the application process of the level gauge, du...

Problems solved by technology

However, this kind of maintenance work not only causes the inconvenience of measurement and the reduction of measurement efficiency, but also because the distribution pressure of carbon black in the powder carbon tank is about -1.5KPa ~ 1.5KPa, therefore, when the working pressure in the powder carbon tank is negative pressure When the powder charcoal tank is opened, a certain amount of air will be sucked into the powder charcoal tank, which may easily cause the explosion of combustible gas in the powder charcoal tank; when the working pressure in the powder charcoal tank is in the positive pressure zone, the carbon black in the powder charcoal tank is easy Jetting out, causing carbon black pollution to the environment
