Description

Technical Field

[0001] The utility model belongs to the technical field of dust removal in tobacco factory workshops, and in particular relates to a grid-based single-machine vacuum cleaning system. Background Art

[0002] At present, a large amount of dust is generated in the production process of cigarette factory workshops. The sources of dust are mainly from the following aspects: material overflow, equipment leakage, dust caused by drop, dust escape, etc. The main way to clean dust in cigarette factories is compressed air blowing. Although the cleaning efficiency is high, it has defects. Compressed air blowing will cause dust to "move" and cause secondary pollution, especially when dust "moves" to steel grilles, pipelines, bridges and grids, it will be difficult to clean. Dust is sucked into the air duct of the air conditioner by the return air outlet of the air conditioner, polluting the entire air system of the air conditioner.

[0003] Some tobacco factories are aware of the shortcomings of positive pressure cleaning and have tried to use negative pressure vacuuming. However, there are shortcomings: (1) When using the negative pressure vacuuming of the original dust removal system, the negative pressure is too low and is not suitable as a cleaning and dust suction power source. (2) When using the negative pressure of the vacuum system used by the wrapping machine to vacuum, the pressure is too high and the suction nozzle is difficult to control. (3) When using a mobile vacuum cleaner for cleaning, the vacuum cleaning efficiency is not high. In addition, there are the following troubles when using a mobile vacuum cleaner: (1) It is inconvenient to take and put. The machine must be taken from a relatively hidden place and moved to a place with a power supply. (2) Power supply hazards. When people pass over the line, step on the line, or cross obstacles, there will be tension, causing the power plug to fall off or poor contact. (3) Noise problems. When working, the operator is always near the noise source.

[0004] When using negative pressure vacuuming, the wind resistance inside the corrugated hose is large when it is wound, which will cause loss of vacuum. At the same time, it is very troublesome to store the hose: (1) The hose of the mobile vacuum cleaner is wound and stacked on the vacuum cleaner. (2) The vacuuming system of the negative pressure system is to set a hose plug interface at the terminal of the pipe network. When vacuuming, the hose is taken out, the reel is spread out to plug the hose, and the hose is rolled up and sent back to the warehouse after cleaning. (3) When using a hose rotator, the hose is pulled out to meet the vacuuming length when vacuuming. When the hose is recovered, it is necessary to manually and carefully arrange the hose to avoid messy pipes. (4) A hose collection cabinet is set up at the vacuuming site, which also has the problem of pressure loss and the trouble of winding the hose. (5) When using the vacuum hose, people and the hose interfere with each other. Utility Model Content

The plurality of groups of single-machine vacuum cleaning equipment 100 include an on-site fixed vacuum cleaning equipment 107, and a pipe network at a connection point with the on-site fixed vacuum cleaning equipment 107. The pipe network includes a dust suction main pipe 101, and a plurality of dust suction branch pipes 102 connected to the dust suction main pipe 101. One end of the dust suction main pipe 101 is connected to an inlet of the on-site fixed vacuum cleaning equipment 107. An outlet of the on-site fixed vacuum cleaning equipment 107 is connected to an inlet of the dust removal system 300 through a pipe 200. A retractable hose 104 is provided in each dust suction branch pipe 102. A dust suction handle 106 is provided at the front end of the hose 104. A hose restraint device 105 is provided at the end of the dust suction branch pipe 102 for fixing the hose 104.

[0023] The hose 104 and the dust suction branch pipe 102 are of a sleeve-insertion structure, and the outer diameter of the hose 104 is gap-matched with the inner diameter of the dust suction branch pipe 102. The hose 104 can be sucked into the dust suction branch pipe 102 by negative pressure to hide or pull out the hose 104.

[0024] The point where the single-machine vacuum cleaning device 100 is set is the dust collection center, and the maximum operating radius R.

[0025] The dust suction area of ​​the hose 104 is a circle with a radius R.

[0026] A butterfly valve 103 is provided on the dust suction branch pipe 102 .

[0027] The on-site fixed vacuum cleaning equipment 107 includes a side channel high-pressure fan 171, a bag-type dust collecting device 172, a filter 173, a viewing window 174, an ash hopper 178, an ash storage bucket 175 or a closed-air discharger 177 and a muffler 176; the filter 173 is arranged at the front end of the bag-type dust collecting device 172, the ash hopper 178 is arranged at the lower outlet of the bag-type dust collecting device 172, an embodiment of the utility model: the ash storage bucket 175 is arranged at the lower outlet of the ash hopper 178, another embodiment of the utility model: the closed-air discharger 177 is arranged at the lower outlet of the ash hopper 178, the side channel high-pressure fan 171 is arranged on the side of the ash storage bucket 175 or the closed-air discharger 177, the muffler 176 is arranged on the side channel high-pressure fan 171, and the viewing window 174 is opened on the side of the ash hopper 178.

[0028] In this embodiment, the dust removal system 300 can be the ZX series oblique plug-in central dust collection system ZX-2-32 or ZX-1-18 of Puhua Environmental Protection Company.

[0029] The local fixed vacuum cleaning equipment 107 is installed at a fixed position. The horizontal pipe of the dust suction main pipe 101 is laid according to the actual situation, and the vertical pipe is connected to the cleaning point. The cleaning tools include hidden cleaning hose 104, various dust suction ports, etc. A local fixed vacuum cleaning equipment 107 is installed at the place where cleaning is required, and some dust suction points are arranged around the equipment. A hose hiding device is set at each point.

[0030] The on-site fixed vacuum cleaning device 107 adopts a high-power, high-flow side channel high-pressure fan 171, so that the negative pressure can meet both the vacuum cleaning effect and the flexibility and comfort of the vacuum handle 106.

[0031] The high negative pressure efficiently sucks the dust into the bag-type dust collecting device 172 of the local fixed vacuum cleaning equipment 107. A multi-stage dust removal method is adopted to introduce the airflow into the settling area. Large dust particles are directly settled in the dust storage area, and small dust particles are blocked on the surface of the filter bag. The pulse backwash system automatically cleans the filter bag according to the differential pressure. The purified air is discharged from the air duct, and the filtered dust is settled in the dust storage area.

[0032] The single-machine vacuum cleaning device 100 uses one machine with multiple points, and a pneumatic / butterfly valve 103 is installed on the branch pipeline. In order to control wind fluctuations and ensure the cleaning effect, vacuum is allocated one by one according to the cleaning process to select the cleaning points, and the point interlocking control cannot clean and vacuum at the same time.

[0033] During cleaning, the hose 104 can be extended or shortened and restrained according to the vacuum cleaning requirements. This technology has the advantages of vacuum cleaning, overcomes the trouble of hose storage, and reduces negative pressure loss.

[0034] An operation panel and a hose restraint device 105 are installed at the end of the dust suction branch pipe 102. The hose 104 is fixed by the hose restraint device 105 after being pulled out to an appropriate length according to the dust suction. The end of the hose 104 is equipped with a variety of dust suction handles 106 suitable for cleaning. After cleaning, remove the dust suction handle 106, open the hose restraint device 105, and block the hose port by hand, and the hose 104 is sucked into the pipe by negative pressure. After the hose 104 is completely sucked in and hidden, turn off the fan on the operation panel to end the cleaning.
