[0017] One embodiment of this utility model has the following beneficial effects:

[0018] 1. By cleverly setting up several layers of baffles in the dust removal chamber, during the dust removal process, the air and dust sucked into the water surface are trapped in bubbles. As the bubbles rise, they encounter the baffles, which cause them to burst. During the bursting process, the dust is moistened by the water and thus captured in the water, while the air continues to rise. By setting up multiple layers of baffles, the bubbles burst multiple times, allowing as much dust as possible to be captured in the water. When the bubbles burst at the water surface, they contain almost no dust, thus achieving an excellent dust removal effect.

[0019] 2. As air is continuously drawn into the dust removal chamber, it constantly agitates the water in the chamber.

[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] A dust removal device according to this embodiment includes: a dust collection box 1 and a fan (not shown in the figure); the dust collection box 1 includes:

[0033] The housing 11 has a dust removal chamber 111 inside, which is a closed structure;

[0034] An air inlet pipe 12 is installed at the bottom of the housing 11 and is connected to the dust removal chamber 111.

[0035] An exhaust pipe 13 is installed on the top of the housing 11 and is connected to the dust removal chamber 111.

[0036] The partition 14 is a plurality of partitions, each partition 14 being fixed at intervals within the housing 11. Each partition 14 is provided with a plurality of through holes 141. The partition 14 divides the dust removal chamber 111 into a plurality of vertically arranged chambers, and adjacent chambers are connected through the through holes 141.

[0037] The air inlet of the fan is connected to the air outlet pipe 13.

[0038] In use, the inlet pipe 12 is first connected to the dust collection pipe of the production equipment, and a certain amount of liquid is added to the housing 11. The water level needs to cover part or all of the partitions 14. The liquid can be water, mineral oil, or other liquids with strong fluidity. In this embodiment, tap water is added to the dust collection box 1. Then, the fan is started. Since the air inlet of the fan is connected to the dust collection chamber 111 through the air outlet pipe 13, a negative pressure is formed in the dust collection chamber 111 above the water level. Under the action of this negative pressure, external air is drawn in from the inlet pipe 12. Inside the dust collection chamber 111, the air inlet pipe 12 provides a negative pressure to the production equipment to adsorb dust, thereby drawing the dust generated during the production process into the dust collection chamber 111. After external air and dust are drawn into the dust collection chamber 111, large bubbles will form in the water within the dust collection chamber 111. These bubbles contain a large amount of air and dust, and the dust in the air will rise with the bubbles. If the large bubbles rise to the water surface and burst, the air and dust contained within them will be directly released into the air above the water surface and discharged outwards under the negative pressure of the fan. Therefore... To ensure the bubbles burst before reaching the water, this invention cleverly incorporates several layers of baffles 14 within the dust removal chamber 111. These baffles 14 can be arranged at equal or unequal intervals, and the spacing between them can be adjusted according to actual needs. Each baffle 14 divides the dust removal chamber 111 into several interconnected cavities arranged vertically. During the dust removal process, air and dust drawn below the water surface are encased in bubbles. As the bubbles rise, they encounter the baffles 14. The obstruction of the baffle 14 prevents larger bubbles from passing through the through hole 141 and continuing to rise. Due to the buoyancy of the water, the bubbles will burst under the combined effect of the baffle 14 and the buoyancy of the water. During the bursting process, the dust will be moistened by the water and thus captured in the water, while the air continues to rise. By setting multiple baffles 14, the bubbles can burst multiple times, so that as much dust as possible in the bubbles can be captured in the water. When the bubbles burst on the water surface, the bubbles contain almost no dust, thus achieving an excellent dust removal effect. In addition, as air is continuously drawn into the dust removal chamber 111, the air constantly agitates the water in the chamber, causing it to churn. This not only causes bubbles to collide with each other, with the partition 14, and with the inner wall of the chamber 11, resulting in the bubbles breaking and reforming, thus further improving the dust removal effect, but also, due to the continuous churning of the water, washes the inner wall of the chamber 11 and the partition 14, effectively preventing dust from accumulating on the partition 14 or adhering to the inner wall of the chamber 11, making the internal cleaning of the dust removal device of this invention simpler.

[0039] This invention achieves dust removal by capturing dust into the liquid within the dust collection chamber 1. Since there is no filter element, there is no issue of reduced dust removal efficiency due to filter clogging after a period of use, allowing the device to maintain optimal dust removal performance for extended periods. When the dust collection device has been used for a long time and a significant amount of dust accumulates in the liquid, the liquid within the chamber 11 can be replaced to maintain its effectiveness.

[0040] Furthermore, the air intake pipe 12 has an L-shaped structure, with one end of the air intake pipe 12 located outside the housing 11 and extending upward.

[0041] With this configuration, one end of the air inlet pipe 12 can be higher than the liquid level inside the housing 11, thereby effectively preventing the liquid inside the housing 11 from leaking out of the air inlet pipe 12. Even if the dust suction port of the production equipment that needs dust removal is low, the liquid inside the housing 11 will not flow back into the dust suction port of the production equipment because the air inlet pipe 12 extends upward.

[0042] Furthermore, the dust collection box 1 also includes an inlet pipe 15 and an outlet pipe 16. The inlet pipe 15 is located at the upper part of the box body 11 and is connected to the dust collection chamber 111. The inlet pipe 15 is equipped with an inlet switch valve 151. The outlet pipe 16 is located at the bottom of the dust collection box 1 and is connected to the dust collection chamber 111. The outlet pipe 16 is equipped with an outlet switch valve 161.

[0043] By providing the inlet pipe 15, liquid can be easily added to the tank 11. For example, in one embodiment, the inlet pipe 15 is connected to a municipal water pipe. When the inlet valve 151 is opened, tap water can be added to the tank 11. The outlet pipe allows for easy discharge of wastewater from the tank 11. When the outlet valve 161 is opened, the wastewater in the tank 11 can be discharged along the outlet pipe 16. This design makes it easier to replace the liquid in the tank 11. By providing the inlet valve 151 and the outlet valve 161, not only can the opening and closing of the inlet pipe 15 and the outlet pipe 16 be easily controlled, but the inlet pipe 15 and the outlet pipe 16 can also be kept sealed, preventing negative pressure leakage in the dust removal chamber 111 and further improving the dust removal effect.

[0044] Furthermore, the dust collection box 1 also includes a baffle plate 17, which is disposed between the air outlet pipe 13 and the uppermost partition plate 14; an air passage 18 is provided between the baffle plate 17 and the inner wall of the box body 11, and the air outlet pipe 13 is disposed away from the air passage 18.

[0045] During the dust removal process, as gas is continuously drawn into the dust removal chamber 111, the liquid in the chamber will continuously churn, inevitably causing water droplets to rise. These droplets tend to float upwards under negative pressure, eventually passing through the exhaust pipe 13 and entering the fan. This invention uses a baffle plate 17 to block the rising water droplets. When a water droplet floats upwards and touches the bottom surface of the baffle plate 17, it adheres to the baffle plate 17. Since the exhaust pipe 13 is located away from the air outlet 18, the airflow becomes curved and the path is longer. This design effectively blocks most water droplets within the dust removal chamber 111, thus protecting the fan. An air outlet 18 is provided between the baffle plate 17 and the inner wall of the housing 11, allowing air to flow smoothly upwards through the air outlet 18 to the exhaust pipe, creating negative pressure within the dust removal chamber 111.

[0046] Furthermore, the dust collection box 1 also includes a liquid level observation tube 19, one end of which is connected to the lower end of the box body 11 and the other end is connected to the upper end of the box body 11. Both ends of the liquid level observation tube 19 are connected to the dust collection chamber 111, and the liquid level observation tube 19 is at least partially transparent.

[0047] By installing the liquid level observation tube 19, the liquid level inside the tank 11 can be conveniently observed from the outside at any time. When the liquid level is too low, liquid can be added to the tank 11 in a timely manner; when the liquid level is too high, some of the liquid in the tank 11 needs to be drained in a timely manner to ensure that the liquid level inside the tank 11 is maintained at a suitable height. It should be noted that the liquid level observation tube 19 utilizes the principle of communicating vessels. Since both the upper and lower ends of the liquid level observation tube 19 are connected to the dust removal chamber 111, the liquid level in the liquid level observation tube 19 can be kept consistent with the liquid level inside the tank 11.

[0048] Furthermore, the other end of the air intake pipe 12 passes through the inner wall of the housing 11 and extends into the dust removal chamber 111.

[0049] With this configuration, the end of the air inlet pipe 12 can be close to the central axis of the dust removal chamber 111, so that when air enters the dust removal chamber 111 through the air inlet pipe 12, bubbles are formed near the central axis of the dust removal chamber 111. When the bubbles rise, they can be evenly dispersed by the baffle 14. The baffle 14 has a higher utilization rate and a better bubble dispersion effect, thereby improving the dust removal effect.

[0050] Furthermore, a reinforcing plate 112 is provided on the outside of the housing 11, and one end of the air intake pipe 12 is fixedly connected to the reinforcing plate 112.

[0051] The reinforcing plate 112 can reinforce the end of the air intake pipe 12 located outside the housing 11, so that the air intake pipe 12 can be fixed to the outer wall of the housing 11, and the installation of the air intake pipe 12 is more secure.
