Description

Technical Field

[0001] The invention relates to the technical field of dust removal devices, in particular to a square cage array rotary dust removal unit. Background Art

[0002] Dust removal units are suitable for dust collection in industrial enterprises with many fans and large exhaust air volume. Traditional dust removal units have low dust collection efficiency, and their processing capacity and dust removal efficiency cannot be synchronized; dust leakage and equipment system failure to operate may occur. Dust leakage will affect the environment and endanger human health; equipment failure will affect corporate benefits. Therefore, air purification equipment must be installed in production enterprises that are prone to dust generation to provide clean air for the working environment and atmospheric environment.

[0003] Organized movement of dust - dust purification is the most effective way to manage and protect the environment. It protects the health of production operators and the environment. This equipment is suitable for dust collection in large-scale cotton ginning production and processing, grain flour and oil processing, textile processing and various high-dust processing enterprises.

[0004] The composite round cage dust removal unit is currently being promoted and used with high dust removal efficiency and is compatible with enterprises. However, this type of dust removal unit currently has two major drawbacks: 1. There are dead corners at the dust suction point; for example, the patent "Cotton Processing Dust Removal Unit" with application number 201810376717.4 has a dead corner in its suction pipe groove, and the dust in the dead corner cannot be handled manually without stopping the machine. When too much dust accumulates and the extension end of the three-stage dust suction arm cannot be cleaned, the three-stage dust suction arm will deform during the rotation process, and it will also cause a series of problems such as dust accumulation in the filter material, ash infiltration in the filter material, damage to the filter material, overload of the dust suction rotor motor, etc., thereby affecting the dust removal efficiency and the normal operation of the equipment.

[0005] 2. Incomplete dust collection. In actual operation, the composite round cage often has incomplete dust collection. Due to the different properties of dust entering the composite round cage unit, some dust, such as fine sand and oily dust, have a specific gravity that exceeds the design constant wind speed standard. Under the action of gravity, they naturally fall and accumulate on the surface of the filter material. Since the annular filter frame and filter material of the composite round cage are designed horizontally, the overweight dust accumulated on it has nowhere to fall, resulting in incomplete dust collection for a long time. The longer the time, the thicker the dust accumulation, which seriously affects the dust removal efficiency and the normal operation of the equipment.

[0006] The above two drawbacks will seriously affect the dust removal efficiency and even cause equipment damage.

[0007] In addition, the annular filter frame in the composite circular cage dust removal unit has very high precision requirements during the manufacturing process in order to achieve the concentricity of each circle and ensure that each circle is on the same plane. It is very difficult to manufacture and has a very high installation cost. Summary of the invention

[0047] The bottom of the front cabin shakron and the square cage shakron are both provided with dust compactors 76.

[0048] A front debris removal auger 75 is provided at the bottom of the front cabin 2.

[0049] Working principle: dusty air enters the dust removal box 1 through the pipeline, and after the dusty air settles in the front cabin, it passes through the filter 8, and the air and fine dust can continue to pass backward through the filter; most of the fibers will be hung on the filter, and large particles of impurities will be blocked by the filter 8 and then fall into the front impurity removal auger 75 under the influence of gravity. A dust suction arm 5 is provided in front of the filter 8, and a dust suction arm suction port 51 is provided at the rear of the filter 8, close to the filtering working surface of the filter 8, and the front air guide shaft driving motor 56 drives the front air guide shaft driving pulley 58 to drive the front air guide shaft 57 to rotate, and then the front air guide shaft 579 drives the dust suction arm 5 to rotate, and the fibers and impurities blocked by the filter are cleaned and scraped off, and the dust suction arm suction port 51 is used to suck them away from the surface of the filter 8, so as to ensure that the surface of the filter 8 is clean and does not cause serious blockage to affect the filtering effect. The fibers sucked in through the suction port 51 of the dust suction arm are sequentially drawn out through the front air guide shaft 57 and the front exhaust pipe 7 through the front exhaust fan 71, and then the heavier fibers and impurities are separated by the front cabin shaker 73 and discharged by the dust compressor at the bottom thereof, and the lighter dust-containing gas flows back to the front cabin 2 through the front cabin shaker outlet pipe for further dust removal.

[0050] After passing through the filter screen 8, the dusty air enters the cage cabin, and the heavier impurities enter the cage impurity removal auger A81 under the influence of gravity. The lighter dusty air is filtered by the short-pile filter cloth 4 laid on the cage dust filter plate 97 arranged in an array, and the clean air is discharged from the outer air outlet of the cage dust filter plate 97.

[0051] The short-pile filter cloth 4 will adsorb impurities and dust on its surface during filtration, and the square cage air guide shaft driving pulley 91 driven by the square cage air guide shaft driving motor 901 will drive the square cage air guide shaft 9 to rotate, and the rear square cage air guide shaft 9 drives the dust filter suction pipe 96 to rotate. During the rotation process, the impurities and dust blocked by the filter cloth are cleaned and scraped off, and the slit suction port 961 is used to suck them away from the surface of the filter cloth, so as to ensure the cleanliness of the filter cloth surface and prevent blockage, which affects the filtering effect.

[0052] The impurities and dust sucked from the surface of the filter cloth enter the square cage air guide shaft 9, and the square cage exhaust fan 61 sucks out the impurities and dust through the square cage exhaust pipe 6, and then enters the square cage shakron 63 through the square cage exhaust pipe 62 to separate the heavier impurities, and is discharged by the dust compressor at the bottom thereof, and the lighter dust-containing gas enters the reflux square cage cabin 3 through the square cage shakron outlet pipe to continue the dust removal work.

[0053] The dust and impurities between the square cage dust filter plates 97 arranged in the array or on the filter cloth are too heavy and roll into the square cage impurity discharge auger B93 under the influence of gravity for collection and discharge.
