Description

Rotary blowing rotating speed detection device of cloth bag dust collector

Technical Field

The utility model relates to the technical field of bag-type dust collectors, in particular to a rotary blowing rotating speed detection device of a bag-type dust collector.

Background

The bag-type dust collector is a dry dust collector, and most of dust in the flue gas is filtered through the functions of filtering, diffusion, static electricity and the like of a filter bag. Most of the filtered dust falls into a dust hopper below the dust remover due to gravity, is stored in a certain amount and is conveyed into a fixed bin in a proper ash conveying mode. However, a part of dust is attached to the surface of the filter bag, and after a period of time, the resistance of the filter bag is increased more and more, so that the output of a fan in a flue gas system is increased; and along with the increase of the resistance of the filter bag, a part of small-particle dust can pass through the filter bag due to the overlarge differential pressure value, so that the dust removal efficiency is reduced. Therefore, the ash removing device is an important component of the bag-type dust remover.

Rotary blowing is one of many ash removal modes of a bag-type dust remover. The device mainly comprises a pressure reducing valve, a pulse valve, an air storage tank, a pipeline, a rotating motor and the like. When the bag-type dust collector normally operates, the jetting speed is mainly carried out by taking the differential pressure of the dust collector as a judging condition, and the jetting speed is generally divided into 3 gears, namely a low gear, a standard gear and a quick gear. Ensuring that the blowing speed is within a suitable range is a very important factor in ensuring that the ash is removed to the desired level, and it is therefore very important to monitor the rotational speed of the swivel arm.

The rotatory jetting subassembly of monitoring relies on proximity switch to count, and proximity switch installs inside the casing of dust remover, because the outside casing size of dust remover often can customize according to first side's demand, leads to inside rotatory jetting subassembly also to need to customize the installation, and rotatory jetting subassembly can be bigger in some designs with the distance of casing, and proximity switch is too far from rotatory jetting subassembly, adds the interference such as inside dust debris, can lead to monitoring data inaccuracy. Considering again that debris such as dust can produce the scraping wearing and tearing of proximity switch, there is maintenance change's demand, this scheme will close the switch and integrate on the support of installation rotatory jetting subassembly, solves above-mentioned problem.
