Description

Technical Field

[0001] This utility model relates to the field of water curtain cabinet technology, and more specifically to a water curtain cabinet for purifying paint mist. Background Technology

[0002] A water curtain cabinet is an environmentally friendly device used in industrial production to treat waste gas and dust generated during processes such as painting and sanding. It forms a "water curtain" through water flow. When air containing paint particles or dust passes through this water curtain, the pollutants are absorbed or adhered by the water, thereby achieving the purpose of purifying the air. Existing water curtain cabinets [such as the publication number: CN217830503U, a negative pressure external extraction cyclone water curtain cabinet] and [publication number: CN206240214U, a paint spraying water curtain cabinet with automatic exhaust gas treatment function] use a water pump to circulate and pump water from the lower water tank to the overflow position and cyclone bucket, thereby generating a falling water curtain that contacts the exhaust gas (such as paint mist) and carries away the dirt. However, water curtain treatment using only these two methods has the disadvantage of poor water curtain effect and poor purification capacity. Utility Model Content

[0003] The purpose of this utility model is to provide a water curtain cabinet for purifying paint mist in order to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution: This utility model proposes a water curtain cabinet for purifying paint mist, including a cabinet body, a water collection tank located at the lower end of the cabinet body, a water curtain assembly fixed to the cabinet body, an inner cavity formed between the water collection tank, the water curtain assembly and the cabinet body, a paint mist inlet formed between the water collection tank and the water curtain assembly, a vortex tube fixed to the inner cavity, a water return mechanism fixed to the cabinet body, and a controller fixed to the cabinet body. A water pump is installed on the water collection tank to supply water to the return water mechanism. Water is supplied by the return water mechanism to the water curtain component to form a water curtain that flows to the paint mist inlet and then enters through the top of the vortex tube. It also includes several sets of first water spray components, which are respectively connected to the water return mechanism for water supply. The first water spray components are fixedly inserted into the inner cavity outside the cabinet to spray water, and the several sets of first water spray components are located below the vortex tube.

Detailed Implementation

[0013] like Figures 1-2 As shown, this utility model proposes: a water curtain cabinet for purifying paint mist, including a cabinet body 1, with an opening on the left side of the cabinet body for paint mist to enter; The cabinet 1 includes a water collection tank 2 located at the lower end of the cabinet 1, a water curtain assembly 3 fixed to the cabinet 1, an inner cavity 4 formed between the water collection tank 2, the water curtain assembly 3 and the cabinet 1, a paint mist inlet 5 formed between the water collection tank 2 and the water curtain assembly 3, a vortex tube 6 fixed to the inner cavity 4, a water return mechanism 7 fixed to the cabinet 1, and a controller 13 fixed to the cabinet 1. The controller 13 connects to an external power source to supply power to the electrical components and control their opening and closing. A water pump is installed on the water collection tank 2 to supply water to the return water mechanism 7. Water is supplied from the return water mechanism 7 to the water curtain component 3 to form a water curtain that flows to the paint mist inlet 5 and then to the top of the vortex tube 6. The water pump draws the water on the water collection tank 2 into the return water mechanism 7 and then supplies water to the water curtain component 3 and the vortex tube 6 respectively. It also includes a filter layer 10 fixed in the inner cavity 4, an exhaust fan 11 fixed at the top of the cabinet 1, and a lighting lamp 12 fixed on the cabinet 1. The bottom end of the inner cavity 4 is connected to the exhaust fan 11 through the vortex tube 6 and the filter layer 10 in sequence, and the lighting lamp 12 is installed at the top of the inner side of the opening. like Figure 2 As shown, the exhaust fan 11 is started, which sequentially forms wind force in the air filter layer 10, the vortex tube 6, the inner cavity 4 at the bottom of the vortex tube 6, and the paint mist inlet 5. The paint mist in the opening on the right side of the cabinet 1 is drawn into the inner cavity 4 at the bottom of the vortex tube 6 by the wind force of the paint mist inlet 5. During this process, the water curtain component 3 makes initial contact with the water curtain formed at the paint mist inlet 5, and the paint mist carries away the paint dirt and falls down. The water in the vortex tube 6 then carries away the paint dirt in the paint mist and falls down. The paint mist in the vortex tube 6 rises to the air filter layer 10 for further filtration, thus purifying the paint mist. The specific structure of the aforementioned water curtain component 3 is as follows, and in conjunction with, for example... Figures 1-2 As shown: The water curtain assembly 3 includes an overflow trough 31 on the cabinet 1 and a diversion plate 32 fixed on one side of the overflow trough 31. The paint mist inlet 5 is located at the bottom of the diversion plate 32. Water in the overflow trough 31 overflows to the diversion plate 32 to form a water curtain and flows to the paint mist inlet 5. The overflow trough 31 is recessed on the upper side inside the cabinet 1. When water is continuously added to the overflow trough 31, due to the height limitation, the water overflows at the diversion plate 32, and the overflowing water flows onto the diversion plate 32 and is guided to the paint mist inlet 5, thereby forming a plate-shaped downward flowing water curtain.

[0014] The specific structure of the aforementioned water return mechanism 7 is as follows, and in conjunction with, for example... Figures 1-2 As shown: The water return mechanism 7 includes a water inlet pipe 71 with one end connected and fixed to the water pump discharge end, and the water flow is in the water inlet pipe 71; Connect the first regulating valve 72 (which can be a butterfly valve or a ball valve, etc.) that is fixedly installed between the water supply pipes 71. A first water pipe 73 and a second water pipe 74 are respectively connected and fixed to the water supply pipe 71. A first regulating valve 72 is located between the first water pipe 73 and the second water pipe 74. The water in the water supply pipe 71 is diverted between the first water pipe 73 and the second water pipe 74. The amount of water flowing through the first water pipe 73 is adjusted by the first regulating valve 72. The first water pipe 73 is partially inserted into the cabinet 1 and the other end of the first water pipe 73 extends into the overflow tank 31. The first water pipe 73 continuously supplies water into the overflow tank 31. The first water distribution pipe 75 is fixedly connected to the second water pipe 74. The first water distribution pipe 75 is partially inserted into the inner cavity 4 and located at the upper end of the vortex cylinder 6. The first water distribution pipe 75 is provided with a pipe opening that leads to the top of the vortex cylinder 6. The second water pipe 74 is fixed to the front end of the first water distribution pipe 75 for water supply. The first water distribution pipe 75 is inserted into the inner cavity 4 at the front end of the cabinet 1 and located at the top of the vortex cylinder 6. A pipe opening is made at the bottom end of the first water distribution pipe 75 at the corresponding top position of the vortex cylinder 6 so that water can enter the vortex cylinder 6 through the pipe opening.

[0015] It also includes several sets of first water spray components 8, which are respectively connected to the return water mechanism 7 for water supply. The first water spray components 8 are fixed outside the cabinet 1 and penetrate into the inner cavity 4 to spray water. Several sets of first water spray components 8 are located below the vortex tube 6. The first water spray components 8 are introduced into the inner cavity 4 below the vortex tube 6 through the return water mechanism 7 and fall to increase the amount of water curtain formed, so as to improve the purification capacity. As shown in the figure, the first water spray component 8 is provided with two sets to further increase the amount of water curtain formed; The second water spray component 9 is connected to the water return mechanism 7 for water supply and is fixed on the cabinet 1. It is used to spray water to the paint mist inlet 5. The second water spray component 9 is introduced into the opening position by the water return mechanism 7 and sprayed into the paint mist inlet 5 to increase the amount of water curtain formed, thereby further improving the purification capacity.

[0016] The structure of the first water spray component 8 described above is as follows, and in conjunction with... Figures 1-2 As shown: The first water spray assembly 8 includes a second water distribution pipe 81 with one end connected and fixed to the second water pipe 74, and several sets of nozzles 82 respectively connected and fixed to the bottom end of the second water distribution pipe 81. The second water distribution pipe 81 partially penetrates the inner cavity 4 and is located below the vortex tube 6. The front end of the second water distribution pipe 81 is fixed to the second water pipe 74 for water supply. The second water distribution pipe 81 penetrates into the inner cavity 4 at the front end of the cabinet 1 and is located below the vortex tube 6. Water is sprayed downward through the nozzles 82, which increases the amount of water curtain formed in the inner cavity 4 (and multiple sets of nozzles 82 are evenly distributed at the bottom end of the second water distribution pipe 81, so that the water curtain formed has good uniformity and high coverage of paint mist air).

[0017] The structure of the second water spray component 9 described above is as follows, and in conjunction with... Figures 1-2 As shown: The second water spray assembly 9 includes a third water distribution pipe 91 that is connected and fixed to the second water pipe 74.
