Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, and more particularly to a pulse single-unit bag dust collector for producing sorbitol. Background Art

[0002] Sorbitol is a white crystalline powder, flake or granule, odorless. With the development of modern industry, the impact of dust on the environment and human health has become increasingly serious. Therefore, a dust collector is required during the production of sorbitol to ensure the workshop environment.

[0003] The pulse bag dust collector has the advantages of high purification efficiency, large gas handling capacity, stable performance, convenient operation, long filter bag life, and small maintenance workload. The dust generated during the production of sorbitol accumulates on the outer surface of the filter bag and continuously increases, causing the resistance of the bag dust collector to rise continuously. To ensure that the equipment resistance does not exceed 1200 Pa and the bag dust collector can continue to operate, the dust on the filter bag needs to be removed regularly. However, the existing dust collectors have the disadvantages of insufficient dust cleaning power and low dust cleaning efficiency.

[0004] Therefore, there is an urgent need for a pulse single-unit bag dust collector for producing sorbitol. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The present utility model will be further described in detail below in conjunction with the drawings and specific embodiments.

[0016] A pulse single-bag dust collector for producing sorbitol, in combination with Figure 1 as shown, includes a bag chamber 1, a clean gas chamber 2, a dust collection chamber 3, a flower plate 4, a filter bag 5, an inspection door 6, a filter screen plate 7, a dust removal device, an intake pipe 9, a pulse valve 10, a spray pipe 11, a main pipe 12, a pulse controller 14, an air outlet 16, a fan 17, and a support leg 18. The dust removal device includes a vibration motor 81 and a dust outlet valve plate 82.

[0017] The dust collection chamber 3, the bag chamber 1, and the clean gas chamber 2 are arranged from bottom to top and are connected.

[0018] The dust collection chamber 3 is an ash accumulation hopper in the shape of a frustum of a cone. A dust removal device is arranged in the ash accumulation hopper. The dust removal device includes a plurality of vibration motors 81 and a dust outlet valve plate 82. The vibration motors 81 are arranged in the ash accumulation hopper. Two vibration motors 81 are provided, and the two vibration motors 81 are arranged on the left and right inner walls of the ash accumulation hopper. The dust outlet valve plate 82 is arranged at the bottom outlet of the ash accumulation hopper to control the ash discharge.

[0019] A plurality of vertically arranged support legs 18 are arranged outside the dust collection chamber 3, and the support legs 18 vertically support the dust collector on the ground.

[0020] An air inlet pipe is respectively arranged on the left and right sides of the lower part of the bag chamber 1, and an air homogenizing mechanism is arranged in the air inlet pipe 9 to homogenize the air flow.

[0021] A filter screen plate 7 is arranged above the air inlet pipe 9 for preliminarily filtering the gas, intercepting large-particle impurities and allowing them to fall into the dust hopper.

[0022] An inspection door 6 is arranged on the side wall of the bag chamber 1 above the filter screen plate 7 to facilitate maintenance by workers.

[0023] A flower plate 4 is arranged above the filter screen plate 7, and filter bags 5 supported by filter cages are arranged at the through holes of the flower plate 4. The filter bags 5 intercept the dust in the gas outside the filter bags 5.

[0024] A jet pipe 11 is arranged in the hole of the flower plate 4. A pulse valve 10 is arranged on the jet pipe 11, and the pulse valve 10 is connected to a pulse controller 14 arranged outside the bag chamber 1. The jet pipe 11 is communicated with a main air pipe 12, and the main air pipe 12 is connected to an air compressor 13 arranged outside the bag chamber 1.

[0025] An air outlet 16 is arranged at the top of the side wall of the clean gas chamber 2, and a fan 17 is arranged at the air outlet 16. The fan 17 discharges the treated air outside the dust collector.

[0026] When the utility model is actually used, the gas enters the bag chamber after passing through the air homogenization in the air inlet pipe. The filter screen plate preliminarily filters the gas, and the impurities fall into the dust collection chamber. After the filter bags secondary-filter the gas, the gas enters the clean gas chamber and is discharged from the dust collector under the action of the fan in the clean gas chamber.

[0027] When dust cleaning is required, the pulse valve is controlled to be opened in sequence by the pulse controller 14, and the high-pressure air released by the air compressor blows each filter bag one by one. The filter bag suddenly bulges, thereby shaking off the dust accumulated on the surface of the filter bag, and the dust falls into the dust collection chamber. After dust cleaning is performed several times, the vibration motor and the dust outlet valve plate are opened, and the dust in the dust collection chamber is shaken off from the dust outlet valve plate out of the dust collector.
