Function of dust collector ash bucket level gauge

the ash bucket of the dust collector is a key component of the dust collection equipment in the process of the experiment. It collects the waste dust in the dust removal process. For the most widely used bag type dust collector, when the flue gas containing a large amount of dust at the air inlet collides with the cloth bag that blocks the dust under a strong negative pressure, the part with a large mass falls directly into the ash bucket with a double lead screw 4 column, However, the dust with small mass is attached to the surface of the cloth bag and mechanically shakes under the action of external force of reverse blowing or pulse air jet valve air flow to achieve the ash removal process. All the cleaned dust falls into the ash bucket. The dust collector under long-term working conditions generally works continuously and cleans the dust in different rooms. At this time, a large number of cleaned dust falls into the ash bucket continuously, but the volume of the ash bucket is limited, Therefore, a feedback signal must be sent to the PLC system before the dust in the ash hopper is filled, so as to arrange time to clean the dust in the ash hopper so as to continue working. At this time, a controllable ash unloading valve will be installed in the ash hopper to facilitate the transfer of dust. The feedback signal in the above process depends on the level gauge, or there is dirt or too large gap between the steel ball of the buffer valve and the inlet. The level gauge is an instrument installed in the ash hopper to detect the position of dust in the ash hopper. With it, we can know how much ash there is in the ash hopper, so as to organize the work. The level meter can be divided into radio frequency admittance level controller, heavy hammer level meter, resistance displacement level meter, resistance rotation level meter, tuning fork level switch

the level meter is widely used to measure liquid, solid and other position parameters. It will be difficult to directly measure the position in the equipment with the rapid growth of the demand of new and old customers. It can output electrical signals through various engineering principles, which is convenient to realize its automatic control. Generally speaking, the level gauge is an instrument for measuring the position of objects
