Description

Technical Field

[0001] The invention relates to the technical field of plastic woven bag production, in particular to a dust removal device for plastic woven bag production. Background Art

[0002] Plastic woven bags are bags woven from plastic fibers, usually made of materials such as polypropylene. Plastic woven bags are widely used in agriculture, construction, transportation and other fields due to their durability, lightness and waterproofness. In the production process of plastic woven bags, a large amount of plastic dust and particles will be generated. If not handled in time, it may affect product quality, employee health and production environment. When plastic woven bags are cut, some plastic dust and particles will be generated. Traditional dust removal devices are mostly installed above the cutting station. The negative pressure is generated by exhausting air to suck the plastic dust and particles into the channel to reduce the impact of plastic dust and particles on the working environment. However, during dust removal, since some plastic dust and particles are large or large, it is easy to cause blockage in the channel, which requires frequent manual cleaning and maintenance. In severe cases, the machine needs to be shut down, which will affect the overall processing efficiency of the plastic woven bags.

[0036] After one group of ventilation filter plates 222 has been filtered for a long time, the dust storage bin stores more filtered matter, causing blockage in the ventilation filter plates 222. At this time, it is necessary to rotate and replace the next group of ventilation filter plates 222 for use. At the same time, the dust storage slots 221 that originally stored more filtered matter correspond to the waste removal slots 212 and the waste removal grooves 232. At this time, the cleaning liquid output pump mechanism and the second valve 2327 can be controlled to open, and the first valve 2324 can be closed.

A filter top plate 45 is fixedly installed, and the fifth tube 42 is located between the filter bottom plate 44 and the filter top plate 45. A cover 46 is detachably installed on the side of the processing outer frame 41 away from the fifth tube 42. The filtered material discharged after cleaning is introduced into the processing outer frame 41 through the fifth tube 42, and is placed between the filter bottom plate 44 and the filter top plate 45. The gas is filtered by the filter bottom plate 44 and the filter top plate 45 respectively, and the gas is discharged through the exhaust pipe 411. The filtered liquid is retained at the bottom of the processing outer frame 41. By opening the fourth valve 431, the filtered liquid is discharged through the recovery pipe 432 for recycling. The filtered material is retained on the filter bottom plate 44, and can be cleaned out later by opening the cover 46.

[0038] Working principle: When in use, the entire dust removal device is fixedly installed at a suitable position of the plastic woven bag production and cutting station through the installation top frame 1. When installed and used, the length and structure type of the dust suction outer frame 5 are selected according to the different plastic woven bag cutting stations, and after the entire device is installed, the dust suction ports at the bottom of the two dust suction outer frames 5 correspond to the woven bag cutting parts, so as to facilitate the precise suction of plastic dust and particles generated at the woven bag cutting parts, connect the end of the dust suction hose 34 to the suction end of the dust suction system, connect the end of the air hose 7 to the output port of the dry air output pump mechanism, and connect the end of the liquid hose 71 to the output port of the cleaning liquid output pump mechanism; The dust collection system and the third valve 32 are controlled to open, and negative pressure is formed at the dust collection ports at the bottom of the two dust collection outer frames 5. The plastic dust and particles generated at the cutting part of the woven bag are accurately sucked. The dust and particles are sucked into a corresponding group of dust storage grooves 221 through the dust collection outer frames 5 on both sides and the dust removal grooves 211, and are primarily filtered through a corresponding group of ventilation filter plates 222. The filtered materials are retained in the corresponding dust storage bin, so that the dust and particles are effectively filtered and removed at the primary level. After filtering, they are introduced into the secondary outer frame 31 through the corresponding dust removal grooves 231, the connecting suction pipes 2313 and the third pipe 311, and are secondarily filtered through the filter core 33, effectively improving the filtering and dust removal effect of dust and particles. After one group of ventilation filter plates 222 has been filtered for a long time, a large amount of filtered matter stored in the dust storage bin causes blockage of the group of ventilation filter plates 222. At this time, it is necessary to rotate and replace the next group of ventilation filter plates 222 for use. By controlling the driving worm 242 to rotate, the driven worm gear 241 is driven to rotate, thereby controlling the rotating shaft 24 to drive the primary removal middle cylinder 22 to rotate. The primary removal middle cylinder 22 rotates between the primary outer cylinder 21 and the primary removal inner cylinder 23, and flexibly adjusts the positions of the multiple groups of dust storage grooves 221 so that each group of dust storage grooves 221 corresponds to the dust removal grooves 211 and the dust removal grooves 231, so that the multiple groups of ventilation filter plates 222 correspond to the dust removal grooves 211 and the dust removal grooves 231 in turn, so that different groups of ventilation filter plates 222 are used to perform primary filtering on the inhaled plastic dust and particles, thereby preventing the filtered matter produced by the filtration from clogging the ventilation filter plates 222. At the same time, the dust storage groove 221, which originally stored more filtered materials, corresponds to the waste removal groove 212 and the waste removal groove 232. At this time, the cleaning liquid output pump mechanism and the second valve 2327 can be controlled to open, and the first valve 2324 can be closed. The cleaning liquid is introduced into the two waste removal grooves 2321 through the liquid connecting hose 71, the second tube 2328, and the liquid injection tube 2326, and enters the waste removal groove 232, and then enters the corresponding dust storage groove 221, and the accumulated filtered materials are cleaned through the waste removal groove 212 and discharged into the two waste removal frames 6, and then through the waste removal pipe head 61 and the waste removal pipe head 62. The main pipe 62 and the installation pipe 63 are introduced into the processing mechanism 4 to automatically clean and discharge the filtered material without manual cleaning. After the filtered material is cleaned and discharged, the dry air output pump mechanism and the first valve 2324 are controlled to open, and the second valve 2327 is closed. The dry air is introduced into the two waste removal grooves 2321 through the liquid connecting hose 71, the second pipe 2328, and the liquid injection pipe 2326, and enters the waste removal groove 232, and then enters the corresponding dust storage groove 221 to dry the corresponding ventilation filter plate 222, so as to facilitate the subsequent use of the ventilation filter plate 222; The filtered material discharged after cleaning is introduced into the processing outer frame 41 through the fifth tube 42, and placed between the filter bottom plate 44 and the filter top plate 45. After being filtered by the filter bottom plate 44 and the filter top plate 45 respectively, the gas is discharged through the exhaust pipe 411, and the filtered liquid is retained at the bottom of the processing outer frame 41. By opening the fourth valve 431, the filtered liquid is discharged through the recovery pipe 432 for recycling, and the filtered material is retained on the filter bottom plate 44, and can be cleaned out later by opening the cover 46.
