Sand and gravel line dust collector

Sand and gravel line dust collector

The dust collector for sand and gravel line is a dust removal equipment specially used for sand and gravel aggregate production line, which is mainly used to collect and remove dust generated during the production process. The following is a detailed introduction and advantages of the product:

Structural composition:

• Dust collector body:

usually welded with steel plates, with good sealing and stability, is the main part of the equipment, and provides support and protection for the internal filter components, cleaning devices, etc.

• Filter bag:

It is a key component of the dust collector, generally made of polyester fiber and other materials, with good filtering effect and wear resistance, can effectively block dust particles and allow clean gas to pass.

• Pulse blowing device:

One of the core parts, compressed air is sprayed into the filter bag through the blowing pipe to make the filter bag vibrate, thereby shaking off the dust on the surface of the filter bag and ensuring the continuous filtering capacity of the filter bag.

• Ash hopper:

used to collect the shaken dust for subsequent cleaning and processing. The design of the ash hopper usually takes into account the accumulation and discharge of dust, and may be equipped with an ash unloading device, such as a star-shaped ash unloading valve or a screw conveyor.

• Cleaning control system:

responsible for controlling the work of the pulse jet device, automatically performing cleaning operations according to the set parameters, ensuring the stable operation of the dust collector and good dust removal effect.

• Inlet and outlet:

Dust-containing gas enters the dust collector from the air inlet, and the clean gas after filtering by the filter bag is discharged from the air outlet.

• Working principle:

After the dust-containing gas enters the dust collector, the dust is retained on the surface of the filter bag through the filtering action of the filter bag, while the clean gas enters the clean air chamber through the filter bag and is discharged by the fan. As the filtration proceeds, the dust on the surface of the filter bag gradually increases, resulting in increased pressure loss. When the set pressure loss value is reached, the cleaning control system will start the pulse jet device to clean the filter bag. At this time, compressed air is sprayed into the filter bag through the spray pipe, causing the filter bag to vibrate, thereby shaking the dust into the ash hopper.

Advantages and characteristics:

• High dust removal efficiency:

It can effectively remove dust generated in the production process of sand and gravel aggregates, with a dust removal efficiency of more than 99.9%, and the dust concentration of the outlet gas is low, meeting environmental protection requirements.

• Good cleaning effect:

The pulse jet cleaning method is adopted, and the cleaning force is strong. It can completely remove the dust on the filter bag, avoid the secondary adsorption of dust, ensure the filtering performance of the filter bag, and also extend the service life of the filter bag.

• Compact structure:

It occupies a small area, which is convenient for installation and layout in the sand and gravel production line, and will not take up too much space.

• Stable and reliable operation:

The structural design of the equipment is reasonable, with few mechanical moving parts, low failure rate during operation, and can operate stably for a long time under harsh working conditions.

• High degree of automation:

The cleaning control system can automatically perform cleaning operations, reducing the need for manual intervention, reducing the labor intensity of workers, and also improving the operating efficiency of the equipment.

• Strong adaptability:

It can adapt to sand and gravel aggregate production lines of different sizes, and has good dust removal effects for dust generated by different types of sand and gravel production equipment.

• Convenient maintenance:

The equipment adopts a modular design, which is convenient for maintenance and replacement of parts, reducing the maintenance cost of the equipment.

• Environmental protection and energy saving:

While effectively removing dust, it can reduce energy consumption, reduce the energy consumption and operating costs of enterprises, and meet the requirements of environmental protection and energy saving.
