[0032] The following further elaborates on the embodiments of the present utility model with reference to the drawings.
[0033] According to some embodiments of the present utility model, referring to Figures 1 to 3 , the dust removal and exhaust device includes a box body 100 and a height adjustment component 300. A baffle 101 is provided inside the box body 100 to divide the inner cavity of the box body 100 into a first area 110 and a second area 120. The first area 110 is located on the left side of the second area 120, and the baffle 101 is vertically arranged. The first area 110 is respectively communicated with the inner cavity of the air inlet pipe 210 and the inner cavity of the water inlet pipe 220. A filter screen 170 is provided in the second area 120 to divide the second area 120 into an exhaust area 122 and a drainage area 121. The drainage area 121 is located below the exhaust area 122. The drainage area 121 is communicated with the inner cavity of the second drain pipe 240. An exhaust component 140 is provided on the top wall of the box body 100 to communicate with the exhaust area 122. The height adjustment component 300 is installed inside the box body 100 and can move in the up and down direction. A connection channel 130 communicating the first area 110 and the second area 120 is formed between the upper end of the height adjustment component 300 and the top wall of the box body 100.
[0034] Water enters the first area 110 through the water inlet pipe 220. The water level in the first area 110 gradually spreads upward and overflows into the second area 120 through the connecting channel 130. When the gas carrying dust enters the first area 110 through the air inlet pipe 210, the gas contacts the water surface to purify the gas, so that the dust adheres to the water surface and follows the water to overflow from the first area 110 into the exhaust area 122 of the second area 120. Subsequently, the water retains the dust on the filter screen 170 through the filter screen 170, and the water enters the drainage area 121 from the exhaust area 122 through the filter screen 170, and then is discharged through the second drain pipe 240. The gas purified by the water enters the exhaust area 122 from the first area 110 and is discharged through the exhaust assembly 140. This dust removal and exhaust device can separate the gas and dust from each other, ensure the discharged gas is clean, avoid polluting the environment, and can be used for dust removal and exhaust at the production site of high-definition protective films and other films with high cleanliness requirements.
[0035] It can be understood that by adjusting the distance between the upper end of the height adjustment component 300 and the top wall of the box body 100, the height of the connecting channel 130 in the vertical direction can be adjusted, so as to adapt to the gas flow rate through the air inlet pipe 210.
[0036] It should be noted that by adjusting the height adjustment component 300, the height of the water level in the first area 110 can be changed. According to the pressure of the gas carrying dust in the air inlet pipe 210, the height of the water level in the first area 110 is adjusted to a suitable position to ensure the exhaust effect and the smooth operation of the equipment. If the distance between the water level and the outlet of the air inlet pipe 210 is too far, it is not conducive to the dust falling on the water surface and then contacting the water, affecting the exhaust effect; if the distance between the water level and the outlet of the air inlet pipe 210 is too close, it will hinder the smooth flow of the air flow and the dust discharged from the air inlet pipe 210, affecting the smooth operation of the equipment.
[0037] According to some embodiments of the present invention, referring to Figure 3 and Figure 4 , the height adjustment component 300 includes a sliding plate 310 and a tightening bolt 320. The sliding plate 310 is slidably connected to the box body 100, and the sliding plate 310 fits against the baffle 101 to prevent the water in the first area 110 from flowing into the second area 120 through the gap between the sliding plate 310 and the baffle 101. When the sliding plate 310 slides to a specified position in the vertical direction, the tightening bolt 320 can pass through the box body 100 and press the sliding plate 310 to make the sliding plate 310 relatively fixed to the box body 100, that is, to make the sliding plate 310 relatively fixed to the baffle 101.
[0038] Furthermore, referring to Figure 4, on the inner sidewall of the box body 100, there are guide grooves 330 extending in the up and down direction. The two guide grooves 330 are respectively located on the front sidewall and the rear sidewall of the box body 100. The front and rear sides of the sliding plate 310 are respectively inserted into the two guide grooves 330. The guide grooves 330 can guide the sliding plate 310 to move in the up and down direction, preventing the sliding plate 310 from deviating.
[0039] Further, referring to Figure 4 , in the box body 100, there is a first cross bar 340 extending in the front and rear direction. The two ends of the first cross bar 340 are respectively fixedly connected to the inner sidewall of the box body 100. One side of the first cross bar 340 is in contact with the sliding plate 310. The first cross bar 340 is provided with a plurality of threaded holes 341 spaced along the front and rear direction. A plurality of tightening bolts 320 correspond to the plurality of threaded holes 341 one by one. The tightening bolts 320 pass through and are threadedly connected to the threaded holes 341. The tightening bolts 320 can press the sliding plate 310 to make the sliding plate 310 relatively fixed to the first cross bar 340.
[0040] Further, referring to Figure 4 , in the box body 100, there is a second cross bar 350 located on the right side of the first cross bar 340. The second cross bar 350 extends in the front and rear direction. The two ends of the second cross bar 350 are respectively fixedly connected to the inner sidewall of the box body 100. The left side of the second cross bar 350 is in contact with the sliding plate 310, and the right side of the second cross bar 350 is in contact with the baffle 101. The second cross bar 350 can play a role in blocking water, preventing the water in the first area 110 from flowing into the second area 120 through the gap between the sliding plate 310 and the baffle 101.
[0041] According to some embodiments of the present invention, referring to Figure 2 , the exhaust assembly 140 includes a plurality of exhaust holes 141. The top wall of the box body 100 is provided with a plurality of exhaust holes 141. The gas entering the exhaust area 122 can be discharged through the exhaust holes 141.
[0042] According to some embodiments of the present invention, referring to Figure 2 , the box body 100 is provided with a filter cotton 142. The filter cotton 142 covers the exhaust assembly 140. The filter cotton 142 can perform secondary filtration on the gas. The gas purified by water is discharged after being filtered by the filter cotton 142 through the exhaust assembly 140, improving the quality of the gas discharged into the environment.
[0043] According to some embodiments of the present invention, referring to Figure 1 and Figure 2 , the top wall of the box body 100 is provided with a connecting hose 150. The connecting hose 150 is connected to the air inlet pipe 210. The connecting hose 150 plays a buffering role of flexible connection, preventing the connection of the pipeline from being damaged by collision.
[0044] According to some embodiments of the present utility model, with reference to Figure 3 and Figure 4 , an annular bracket 160 is provided in the second region 120. The outer sides of the annular bracket 160 are fixedly connected to the baffle 101 and the inner side wall of the box body 100 respectively. The filter screen 170 is placed on the annular bracket 160. The filter screen 170 can be easily taken out for cleaning and then placed on the annular bracket 160.
[0045] According to some embodiments of the present utility model, the first region 110 is communicated with the inner cavity of the first drain pipe 230. After the airflow carrying dust contacts the water in the first region 110, some dust sinks to the bottom of the first region 110 due to the action of gravity because the contact time with water is too long. Therefore, the first drain pipe 120 is provided to facilitate the cleaning and discharging of the dust sinking to the bottom of the first region 110. The first drain pipe 230 can discharge the water and dust in the first region 110, avoiding the accumulation of dust at the bottom of the first region 110.
