Description

reverse dust collector

technical field

The invention relates to a dust collector, in particular to a filter cartridge dust collector.

Background technique

Cartridge dust collector is a kind of dust collector with filter cartridge as filter element and pulse injection or reverse injection. The structure is composed of airflow distribution distribution plate, filter cartridge and electric control device; the high-speed airflow carrying dust decelerates and settles after entering the dust removal chamber, and the dust adheres to the filter; if the mesh is too large, it will not be able to remove dust efficiently, and if the mesh is too small, it will Clogging occurs after a short period of use, which affects normal operation; therefore, the filter screen of the traditional dust collector is not effective; in addition, when purifying different gases, it is necessary to replace different filter screens to ensure the most efficient dust removal effect; at the same time , The traditional filter cartridge adopts the negative pressure back blowing method in the cleaning process, which is easy to cause the dust to rise again, which brings a lot of inconvenience to the cleaning.

Contents of the invention

In view of the above problems, the present invention provides a reverse dust collector, which can efficiently purify various dusts, facilitate dust cleaning operations, and effectively prevent dust from being raised again.

In order to solve the above problems, the technical solution adopted in the present invention is: the reverse dust collector includes a dust removal chamber, a dust removal cylinder, a purification chamber and an ash hopper; the purification chamber is placed above the dust removal chamber, and the ash hopper is placed below the dust removal chamber A partition is installed between the purification chamber and the dust removal chamber; an air intake pipe is installed on the side wall of the dust removal chamber, and an exhaust pipe is installed on the side wall of the purification chamber;

Each of the dust-removing cylinders is installed vertically in the dust-removing chamber, and the top of each of the dust-removing cylinders is equidistantly installed on the partition; the dust-removing cylinder includes an outer cylinder, an inner cylinder and an isolation ring; the outer cylinder and the The inner cylinder is coaxially sleeved, and the outer cylinder and the inner cylinder are respectively driven by two drivers fixed on the partition to rotate freely; above the partition, a lifting plate is installed in parallel, and each isolation ring is fixed on the lifting plate The lower surface of the spacer ring is coaxial with the inner cylinder, and the lower end of each spacer ring extends between the inner cylinder and the outer cylinder; the outer ring surface of the spacer ring is divided into two upper and lower rings in the vertical direction, and the lower The surface of the ring is smooth, and the surface of the upper ring is distributed with raised particles.

The beneficial effects of the present invention are: the gas carrying dust enters the dust removal chamber from the air intake pipe, the large particle dust is directly settled in the ash hopper, and the small particle dust is adsorbed on the dust removal cylinder during the process of floating with the gas; During the process, adjust the driver to rotate the inner cylinder and the outer cylinder in the opposite direction, and adjust the speed of the inner cylinder and the outer cylinder to an appropriate ratio, so that the inner cylinder and the outer cylinder maintain a large speed difference. After the dust passes through the outer cylinder and the inner cylinder The direction of rotation is opposite, the dust and the inner cylinder have a relatively high speed, so there is a large frictional force, and the dust can be efficiently adsorbed in the inner cylinder; at this time, the present invention can handle fine dust with smaller particles; when the dust particles are large and the concentration When it is low, reduce the speed ratio of the outer cylinder and the inner cylinder or make the inner cylinder and the outer cylinder rotate in the same direction. At this time, the dust removal cylinder has double dust removal functions, and the dust removal effect is extremely obvious.

Compared with traditional dust collectors that replace different dust removal cylinders for different dusts, the present invention adapts to the dust of different particles by adjusting the steering and rotation speed of the inner cylinder and outer cylinder, so that the dust removal cylinder can effectively capture dust, which not only simplifies the dust removal process but also improves the efficiency of dust removal. the purification effect.

During the cleaning operation, move the lifting plate to make the upper ring belt of the isolation ring contact the inner cylinder and the outer cylinder; because the surface of the upper ring belt is distributed with raised particles, with the rotation of the outer cylinder and the inner cylinder, the outer cylinder and the inner cylinder will Different degrees of vibration shake off the dust quickly; compared with the traditional dust cleaning method, the present invention cleans dust quietly and efficiently, and effectively prevents dust from being raised again.

As preferably, electromagnetic sheets are equidistantly installed on the cylinder nets of the inner cylinder and the outer cylinder, and the directions of the magnetic poles of each electromagnetic sheet are inconsistent; The outer cylinder rotates asynchronously, and the electromagnetic sheets on the cylinder net attract or repel each other when they are close to each other, so the cylinder net produces lateral vibration, which further promotes the shaking of dust.

As a further preference, the electromagnetic sheet on the inner cylinder is placed on the inner peripheral surface of the cylinder net of the inner cylinder; in order to prevent excessive dust from polluting the electromagnetic sheet, thereby prolonging the service life of the electromagnetic sheet.
