Description

Technical Field

[0001] This utility model belongs to the field of industrial dust removal, and in particular relates to a water-type dust collection device. Background Technology

[0002] In metal processing, metallurgy, and other industrial production processes, large amounts of impurities such as metal dust and acidic aerosols are often generated. These impurities not only pollute the working environment but can also seriously affect the health of operators. Therefore, how to effectively remove these impurities and maintain a clean and safe working environment has become an urgent problem to be solved in industrial production. Utility Model Content

[0003] In view of this, the present invention aims to propose a water-based dust collection device, which improves dust removal efficiency and ensures a clean and safe working environment by optimizing the box structure, baffle design and water level observation device.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows: A water-based vacuum cleaner includes an upper water tank, a lower water tank, a fan, and a baffle assembly. The upper water tank is installed above the lower water tank to form a whole water tank. The blower is installed on the top of the upper water tank and is connected to the upper water tank. The upper water tank and the lower water tank are connected. The baffle assembly is installed inside the upper water tank. Water is poured into the lower water tank. The length of the lower water tank is greater than that of the upper water tank, so that one side of the whole water tank is open. The upper water tank has a maintenance port on the front and an air inlet on the rear, while the lower water tank has a drain outlet at the bottom. The fan is used to generate suction to draw dust into the upper water tank through the air inlet. The baffle assembly and water are used to absorb and filter the dust entering the upper water tank. The dust dissolves in the water, and clean air is discharged through the fan.

[0005] Furthermore, the baffle assembly includes a first baffle, a second baffle, a third baffle, and a fourth baffle; the two sides of the first baffle, the second baffle, the third baffle, and the fourth baffle are sequentially installed to the side wall of the upper water tank. The first baffle plate has an L-shaped cross-section, with its upper end connected to the top of the air inlet and its lower end flush with the horizontal plane. The No. 2 baffle has an L-shaped cross-section that bends in the opposite direction to the air inlet, and the lower end of the No. 2 baffle bends and disappears into the horizontal plane; the No. 1 baffle is equipped with a curved plate, and a channel opening is formed between the curved plate and the No. 2 baffle; The No. 3 baffle has an L-shaped cross-section that bends in the opposite direction to the air inlet. The upper end of the No. 3 baffle is higher than the curved plate, and the lower end of the No. 3 baffle is submerged in the horizontal plane. The fourth baffle plate has an L-shaped cross-section. The upper end of the fourth baffle plate is installed above the first baffle plate, and the lower end of the fourth baffle plate is at a distance from the horizontal plane.

[0006] Furthermore, the housing of the first baffle plate is also equipped with a filter plate. The filter plate has an L-shaped cross-section. The upper end of the filter plate is installed above the horizontal plane and below the air inlet, and the lower end of the filter plate is submerged in the horizontal plane and flush with the lower end of the first baffle plate. The filter plate is provided with a number of filter holes. The No. 1 baffle plate, filter plate, No. 2 baffle plate, curved plate, No. 3 baffle plate, and No. 4 baffle plate form a dust removal channel.

[0007] Furthermore, the lower water tank is equipped with a partition, and the side wall of the upper water tank is installed on the upper part of the partition. The lower end of the partition does not extend beyond the horizontal plane and there is a gap between it and the bottom surface of the lower water tank.

[0008] Furthermore, the lower water tank is provided with a slag removal port near the partition, and the slag removal port is covered with a cover plate with plexiglass.

[0009] Compared with the prior art, the water-based vacuum cleaner of this utility model has the following advantages: (1) The water-type dust collection device described in this utility model has a baffle plate assembly that forms a tortuous dust collection channel: after the airflow enters from the air inlet, it is forced to turn multiple times by the baffle plate to form a vortex state, which greatly prolongs the residence time of the airflow in the device, avoids the dust from "rapidly flowing through", and allows the dust to have more contact opportunities with the water, thereby improving the adsorption and dissolution efficiency.

[0010] (2) The water-type dust collection device described in this utility model has a vortex formed by the airflow in the deflection path, which causes dust particles to be separated from the airflow due to inertia: large dust particles are "thrown" by the vortex to the water body or the surface of the deflection plate and are directly captured by the water; small dust particles are fully mixed with the water body and dissolved under the disturbance of the vortex, which solves the problem of insufficient capture of small particles by traditional straight-channel water dust collection.

[0011] (3) The water-type dust collection device described in this utility model will interact with the water in a turbulent manner when the airflow passes through the No. 2 baffle plate and enters the horizontal area. Compared with the straight airflow, the turbulent state greatly increases the contact area between the air and the water, making it easier for the dust to be adsorbed by the water and significantly improving the dust removal efficiency.

[0012] (4) The water-type dust collection device described in this utility model has a dual effect of coarse filtration and fine filtration. When the airflow passes through the filter plate, large dust particles are filtered out by the filter holes. Attached Figure Description

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] A water-based vacuum cleaner, such as Figures 1-3 As shown, it includes an upper water tank 1, a lower water tank 2, a fan 3, and a baffle assembly 4; The upper water tank 1 is installed above the lower water tank 2 to form a whole water tank. The blower 3 is installed on the top of the upper water tank 1 and is connected to the upper water tank 1. The upper water tank 1 and the lower water tank 2 are connected. The baffle assembly 4 is installed inside the upper water tank 1. Water is poured into the lower water tank 2. The length of the lower water tank 2 is greater than that of the upper water tank 1, so that one side of the whole water tank is open. The upper water tank 1 has a maintenance port 11 on the front and an air inlet 12 on the rear. The lower water tank 2 has a drain outlet 22 at the bottom. A shut-off valve is provided on the drain outlet 22. The fan 3 is used to generate suction to draw dust into the upper water tank 1 through the air inlet 12. The baffle assembly 4 and the water are used to absorb and filter the dust entering the upper water tank 1. The dust dissolves in the water, and the clean air is discharged through the fan 3.

[0020] Preferably, the baffle assembly 4 includes a first baffle 41, a second baffle 42, a third baffle 43, and a fourth baffle 44; the two sides of the first baffle 41, the second baffle 42, the third baffle 43, and the fourth baffle 44 are sequentially installed to the side wall of the upper water tank 1. The first baffle plate 41 has an L-shaped cross-section, with its upper end connected to the upper part of the air inlet 12 and its lower end flush with the horizontal plane. The second baffle plate 42 has an L-shaped cross section that bends in the opposite direction to the air inlet 12, and the lower end of the second baffle plate 42 bends and disappears into the horizontal plane; the first baffle plate 41 is provided with a curved plate 45, and a channel opening is formed between the curved plate 45 and the second baffle plate 42. The cross section of the No. 3 baffle 43 is L-shaped and bends in the opposite direction to the air inlet 12. The upper end of the No. 3 baffle 43 is higher than the curved plate 45, and the lower end of the No. 3 baffle 43 is submerged in the horizontal plane. The fourth baffle plate 44 has an L-shaped cross-section. The upper end of the fourth baffle plate 44 is installed above the first baffle plate 41, and the lower end of the fourth baffle plate 44 is at a distance from the horizontal plane.

[0021] Preferably, the housing of the first baffle plate 41 is further provided with a filter plate 46. The filter plate 46 has an L-shaped cross-section. The upper end of the filter plate 46 is installed above the horizontal plane and below the air inlet 12. The lower end of the filter plate 46 is submerged in the horizontal plane and is flush with the lower end of the first baffle plate 41. The filter plate 46 is provided with a plurality of filter holes. The filter plate 46 first intercepts large dust particles, reducing the load on the subsequent baffle plate; the filter holes allow the airflow to be evenly dispersed, eliminating dust removal dead corners; the lower end is submerged in water, which can simultaneously adsorb fine dust that has passed through the filter holes, further improving the dust removal accuracy.

[0022] The No. 1 baffle plate 41, the filter plate 46, the No. 2 baffle plate 42, the curved plate 45, the No. 3 baffle plate 43, and the No. 4 baffle plate 44 form a dust removal channel.

[0023] The height difference between different baffles helps to optimize the airflow path, avoid direct airflow, and improve dust collection efficiency.

[0024] Preferably, the lower water tank 2 is provided with a partition 21, and the side wall of the upper water tank 1 is installed on the upper end of the partition 21. The lower end of the partition 21 does not pass through the horizontal plane and there is a gap between it and the bottom surface of the lower water tank 2.

[0025] Preferably, the lower water tank 2 is provided with a slag removal port 23 near the partition 21, and the slag removal port 23 is covered with a cover plate with an acrylic glass cover. The slag removal port 23 can clean dust without draining the water, reducing operating costs and downtime; the acrylic glass cover plate allows for real-time observation of the sedimentation amount, enabling the determination of cleaning time without opening the cover, simplifying maintenance and reducing secondary dust exchange.

[0026] Preferably, the upper water tank 1 is also provided with a window on its side, which allows observation of the inside of the tank.

[0027] Working principle: Clean water is injected into the chamber until the water level reaches the required level. After the fan 3 starts, a negative pressure is formed in the upper water tank 1. Dust-laden air is drawn into the device through the air inlet 12. The dust-laden airflow is guided by the baffle assembly 4, forming a tortuous vortex. The airflow turns multiple times, making full contact with the water in the lower water tank 2. Large dust particles are first filtered through the filter plate 46. The gas changes direction repeatedly in these tortuous channels. Due to the frequent changes in airflow direction, the tiny particles continue to move in a straight line due to inertia, colliding with the water or the surface of the baffle plate and being further captured by the water. During the deflection process, the airflow will also come into contact with the water film and water droplets formed by the water. The fine particles are further adsorbed, adhered, and settled with the water droplets. When the airflow reaches the air outlet, most of the dust and other impurities have been removed, and the water droplets have been effectively intercepted or separated by the deflection structure, leaving only relatively clean air to be discharged; thus completing the dust removal operation.

[0028] When the airflow reaches the air outlet, most of the dust and other impurities have been removed, and water droplets have been effectively intercepted or separated by the baffle structure, leaving only relatively clean air to be discharged; thus completing the dust removal operation.
