Description

Technical Field

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

[0002] Bag dust collector is a common dust removal device in industrial production processes, and is often used to capture fine, dry, non-fibrous dust. As dust particles accumulate on the surface of the bag, the resistance to dust removal increases. When the pressure difference between the inside and outside of the bag is large, some fine dust particles that have attached to the filter material will be squeezed through, reducing the dust collector effect. Therefore, after the resistance of the dust collector reaches a certain value, it needs to be cleaned in time. Existing technologies generally remove dust by jetting pulsed airflow. When the jetted airflow enters from one end of the bag, the bag expands and shakes off the dust. However, when the spacing between the bags is small, the bag cannot fully expand after inflation, so the dust on the bag cannot be completely shaken off. Utility Model Content

A plurality of symmetrically distributed air pipes 121 are provided on the partition 12, and a cloth bag 4 is provided on the air pipe 121. The lower end of the cloth bag 4 is sleeved on the upper end of the air pipe 121, and the upper end is connected to the top surface of the upper compartment through a tension spring 16. The detachable cloth bag 4 is easy to inspect and replace. The elastic force of the tension spring 16 is used to keep the cloth bag 4 in a straight state at all times, so that the cloth bag 4 can be fully unfolded to prevent the cloth bag 4 from folding and affecting the ventilation area. The air pipe 121 connects the upper compartment and the lower compartment. The upper compartment is provided with a dust scraping mechanism 2, which is located at the symmetrical center of the plurality of air pipes 121. The lower compartment is provided with a dust collecting box 3.

[0024] A machine chamber 11 is provided on the top of the dust collector body 1, a chamber cover 111 is provided on the fixed surface of the machine chamber 11, an operation screen is provided on the side, a fan 112 is provided inside, and the bottom surface of the machine chamber 11 is connected to the upper compartment. The fan 112 is responsible for discharging the gas inside the dust collector body 1 to the outside, and the fan 112 and the internal dust scraping mechanism 2 are controlled by the operation screen. The freely openable chamber cover 111 is convenient for repairing the internal electrical components or the fan 112. A chamber door 13 is provided on one side of the dust collector body 1, and a door handle 131 and a slide buckle 132 are provided on the outer wall of the chamber door 13. A lock buckle 134 that cooperates with the slide buckle 132 is provided on the dust collector body 1, and the chamber door 13 can be locked by using the slide buckle 132 and the lock buckle 134. A boss is provided on the inner wall of the chamber door 13, and a sealing ring 133 is provided on the edge of the boss, and the sealing ring 133 improves the sealing performance of the chamber door 13.

[0025] A dust suction pipe 14 is provided on one side of the dust collector body 1. One end of the dust suction pipe 14 is connected to the lower compartment, and the other end is provided with a flare 142. The flare 142 facilitates the dust suction pipe 14 to collect dust in the air. The flare 142 is connected to the dust suction pipe 14 through a bellows 141. The middle section of the dust suction pipe 14 is also provided with a section of bellows 141. The height and angle of the flare 142 can be flexibly adjusted by using the bellows 141, so that dust removal in a specified area can be achieved. The dust scraping mechanism 2 includes a motor 22, a rotating shaft 23 and a spiral blade 21. The motor 22 is fixedly connected to the partition 12. The output end of the motor 22 is fixedly connected to one end of the rotating shaft 23. The side of the rotating shaft 23 is provided with a spiral blade 21. The motor 22 drives the rotating shaft 23 to rotate, and the rotating shaft 23 drives the spiral blade 21 to rotate. The spiral blade 21 rubs the outer surface of multiple cloth bags 4 from top to bottom at the same time, so that the dust inside the cloth bags 4 is shaken off and falls into the dust collecting box 3 through the air pipe 121. The cloth bag 4 is made of polypropylene fiber, which has the advantages of low price, excellent filtering performance, good filter stripping property and wear resistance.

[0026] The top surface of the dust box 3 is open, and the bottom surface is provided with a plurality of symmetrically distributed pulleys 32, and the inner bottom wall of the lower compartment is provided with a track 15 that matches the pulley 32. A handle 33 is provided on the front of the dust box 3, and the dust box 3 can be easily pushed into or out of the lower compartment by operating the handle 33 under the cooperation of the pulley 32 and the track 15. An opening 31 that matches the dust suction pipe 14 is provided on the side of the dust box 3, and a baffle plate 311 that matches the opening 31 is provided on the inner wall of the dust box 3, and the upper part of the baffle plate 311 is connected to the dust box 3 through a hinge. When the air suction pipe 121 carrying dust enters the dust box 3, the baffle plate 311 opens under the action of air pressure, and the air flow enters the dust box 3. Some larger dust particles fall directly into the dust box 3 under the action of the baffle plate 311, and smaller particles enter the cloth bag 4 along with the air flow.

[0027] The working principle of the specific embodiment of the utility model is as follows: the airflow enters the dust box 3 through the dust suction pipe 14, and then enters the cloth bag 4 through the air pipe 121. The dust particles are retained on the inner wall of the cloth bag 4 under the filtering effect of the cloth bag 4, and the airflow enters the upper compartment through the cloth bag 4, and is drawn out of the dust collector body 1 with the action of the fan 112. When the dust in the cloth bag 4 needs to be removed, the fan 112 stops working. The motor 22 is started, and the spiral blade 21 rotates with the rotating shaft 23. The spiral blade 21 rubs the outer surface of the cloth bag 4 from top to bottom, so that the dust accumulated inside is shaken back into the dust box 3.
