The editor introduces the vibrating screen dust collector in the coal washing plant;
For the sake of job conditions and the natural environment of the factory area, dust removal and purification measures have been taken. In order to improve the environment, only dust collectors can be used for treatment
The dust collector is a key equipment in the dust removal system, and its working condition directly affects the success or failure of the entire system. Therefore, the design, renovation, installation, commissioning, and operation of the dust collector in the coal washing plant are necessary
Every step needs to be arranged. Coal mine dust collectors are mainly divided into mechanical dust collectors, filter dust collectors, wet dust collectors, and electrostatic dust collectors. Among them, the filter type dust collector
The bag filter has the highest efficiency (above). Although mechanical dust collectors have simple structures, low costs, and easy maintenance, their dust removal efficiency is not high. The main disadvantage of wet dust collectors is that they produce
Raw sewage needs to be treated for secondary pollution.

Material requirements for vibrating screen dust collector in coal washing plant:
1. Continuous welding adopts carbon dioxide protection airtight welding and conducts kerosene leakage test.
2. The wall panels should be made flat and not twisted, with a diagonal error of less than 5mm. During on-site installation, the verticality deviation of the columns and wall panels should be less than 5mm, and any deformation of the components during transportation needs to be corrected.
3. The opening position of the flower board should be accurate, with a deviation of no more than ± 0.5mm from the theoretical position.
The materials used for the vibrating screen bag filter and its auxiliary equipment in the coal washing plant, as well as the testing, processing, production, coating, etc. of these materials, shall comply with the manufacturer's standards and the seller's standards.
4. The flatness of the flower board is less than 2/1000, and the diagonal length error is less than 3mm.
Working principle of coal mill bag filter:
When the dusty gas first enters the pre dust collection chamber and encounters obstacles, the direction of the airflow will change. One part of it falls into the ash hopper, while the other part will enter the filtering chamber with filter bags along with the airflow. The dust adheres to the outer surface of the filter bags, and the cleaned air is discharged into the atmosphere by the fan.
The reason why the dust collector of the coal washing plant crusher is warmly sought after is not only because it has good dust removal effect, but also because of its high performance. The specific characteristics are as follows:
1. According to the process conditions, different filter materials and process parameters are used to meet the requirements of different exhaust gas characteristics;
2. According to the process conditions, different filter materials and process parameters are used to meet the requirements of different exhaust gas characteristics;
3. The whole machine can be designed in two ways: online cleaning and offline cleaning.
4. The box and top cover of the dust collector are equipped with flap doors, and diagonal pin fasteners are installed between the top cover and the cleaning room. The performance and usage are improved;
5. The whole machine can be designed in two ways: online cleaning and offline cleaning.
6. The PLC programmable controller used is capable of timed or fixed resistance automatic ash spraying and cleaning, implementing automated operation with low air consumption, ash cleaning, and stable performance;
7. The matching cloth bag eliminates the hidden danger of coal powder explosion;
8. Used for dust removal in coal powder systems, filter materials and measures are taken according to the properties of coal powder;
