Description

Technical Field

[0001] The utility model relates to the technical field of dust removal, in particular to a dust removal device for cement production. Background Art

[0002] A large amount of dust and particulate matter are generated during the cement production process. These pollutants not only have a serious impact on the environment but also pose a threat to the health of workers. Therefore, dust removal devices are particularly important in cement production. Traditional dust removal methods mainly include mechanical dust removal, electrostatic dust removal, and bag dust removal, etc., which help cement production enterprises better meet environmental protection standards, reduce environmental pollution, and promote sustainable development;

[0003] Important equipment related to the existing main body in cement production includes bag filters. It mainly consists of filter bags, a box body, a dust cleaning device, etc. Its working principle is that after the dust-containing gas enters the dust collector, the dust with larger particles naturally settles due to gravity, while the fine dust is intercepted by the filter bags. As the dust on the surface of the filter bags accumulates continuously, the dust cleaning device will perform dust cleaning operations regularly to shake off and collect the dust. There are also electrostatic precipitators, which are composed of electrodes, power supplies, etc., and make the dust charged through a high-voltage electric field and adsorbed and collected by the electrodes. These dust removal devices play a key role in cement production, effectively reducing dust emissions and protecting the environment and the health of workers;

[0004] In the prior art, during the filtering operation of some bag filters, dust is extremely easy to adhere to the inner wall of the box body, which makes the cleaning work extremely troublesome. Moreover, if it accumulates for a long time, the overall performance of the dust collector will also decrease significantly; and some dust cleaning devices use the method of vibrating the filter bags to make the dust fall off, however, the cleaning effect of this method is relatively poor and cannot achieve the ideal cleaning degree. For this reason, a dust removal device for cement production is proposed to solve the above problems. Summary of the Utility Model

Guide rods are fixedly connected to the diagonal corners of the lower part of the bottom plate. A moving block is arranged on the upper side of the middle part of the threaded rod and the guide rod. A long scraping plate is fixedly connected between the left and right moving blocks. A short scraping plate is fixedly connected between the front and rear moving blocks;

[0009] As a further description of the above technical solution: The waste discharging mechanism includes a first motor. A first motor is fixedly connected to the outer front side of the waste discharging pipe. A rotating shaft is fixedly connected to the output end of the first motor. A cross-shaped plate is fixedly connected to the middle part of the rotating shaft;

[0010] As a further description of the above technical solution: A support frame is fixedly connected to the upper left side of the box body.

At the same time, a part of the smaller dust particles will be adsorbed on the surface of the box body. At this time, the second motor drives the threaded rod, so that the moving block installed with the long scraper and the short scraper on the threaded rod and the guide rod can move up and down, thereby cleaning the dust particles adsorbed on the surface of the box body, which can improve the performance of the dust removal device and extend its service life.

[0016] 2. In the present utility model, when the air pump and the spray head and other structures cooperate with each other, the finer dust will be intercepted by the filter bag. As the dust on the surface of the filter bag continues to accumulate, the air pump inflates and transports the gas to the spray pipe through the air delivery pipe, and finally sprays out from the spray head and blows against the upper mouth of the filter bag, so that the dust on the surface of the filter bag can fall off instantly and fall into the ash hopper, thereby solving the problem of low efficiency of the method of vibrating the filter bag to make the dust fall off.
