Description

Technical Field

[0001] This utility model belongs to the field of hardware manufacturing technology, specifically relating to a button painting booth structure with a waste gas recovery and treatment module. Background Technology

[0002] When buttons are painted in a paint booth, the paint on the buttons mixes with the gases inside the booth. These gases contain substances from the paint that can be harmful to the human body. To prevent excessive ingestion, exhaust fans are installed inside the paint booth to remove the gases. These exhaust gases must be treated before they are released.

[0003] The commonly used method for treating exhaust gas is to install a spray unit on the exhaust gas pipeline. The spray unit sprays atomized water droplets into the pipeline. These atomized water droplets mix with the exhaust gas. After mixing, some water falls down the pipeline, while some water adheres to the inner wall of the pipeline. Since the exhaust gas contains paint with strong adhesion, the adhesion of the water mixed with the exhaust gas is enhanced. Some water will adhere to the inner wall of the pipeline for a long time. This adhered water can easily damage the protective layer on the inner wall of the pipeline, leading to corrosion inside the pipeline. Therefore, this application proposes a button-shaped paint booth structure with an exhaust gas recovery and treatment module. Utility Model Content

[0004] The purpose of this invention is to provide a button-shaped paint booth structure with a waste gas recovery and treatment module, in order to solve the problem mentioned in the background art where, when treating the waste gas generated in the paint booth, the spray unit sprays atomized water droplets into the air supply pipe. These atomized water droplets mix with the waste gas, and as they move along the air supply pipe, some water adheres to the inner wall of the air supply pipe for a long time. The adhered water can easily damage the protective layer on the inner wall of the air supply pipe, leading to corrosion inside the air supply pipe.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a button painting booth structure with a waste gas recovery and treatment module, including a painting booth, an air intake pipe, and an air extraction device.

[0019] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0020] like Figures 1-5 As shown in the figure, the present invention provides a button painting booth structure with a waste gas recovery and treatment module, including a painting booth 1, an air intake pipe 2, and an exhaust device. The painting booth 1 is equipped with an oven for painting buttons. The exhaust device is connected to the painting booth 1 through the air intake pipe 2. The exhaust device is used to draw the air in the painting booth 1 away through the air intake pipe 2 located at the top of the painting booth 1. An air inlet needs to be set at the bottom of the painting booth 1. Together with the exhaust device and the air intake pipe 2, they form a gas flow channel. In this way, the gas inside the painting booth 1 is drawn away through the air intake pipe 2 at the top. Toxic gases generated during the button painting process are drawn away by the air intake pipe 2, avoiding the mixing of a large amount of toxic gases in the gas inside the painting booth 1, which can effectively protect the workers inside the painting booth 1.

[0021] In order to treat the exhaust gas transported in the intake pipe 2, an air supply pipe 3 is installed at the intake pipe 2. A spray unit 4 for spraying atomized water is installed at the air supply pipe 3. The spray unit 4 can spray atomized water, which can mix with the exhaust gas transported in the air supply pipe 3. The toxic gases in the exhaust gas are mixed with water to achieve the purpose of treating the toxicity of the exhaust gas.

[0022] The spray unit 4 can be used in various real-time modes. In one mode, a water pump is connected to a water tank, and an atomizing screen is installed at the output end of the water pump. The water tank and water pump are used to supply water, and the water output by the water pump passes through the atomizing screen and is separated into atomized water droplets. These water droplets are used to mix with the exhaust gas.

[0023] Specifically, at the end of the gas pipeline 3, there is a turntable 5, a rotating device 6 connected to the turntable 5 and used to provide rotational thrust to the turntable 5, and a connecting pipe 7 installed on the turntable 5.

[0024] The rotating device 6 can drive the turntable 5 and its connecting pipe 7 to rotate, so that the turntable 5 has at least two states, including a filtering state and a cleaning state.

[0025] More specifically, there are at least two connecting pipes 7, and one of the connecting pipes 7 is equipped with a filter unit for filtering and adsorbing exhaust gas. The filter unit can be a common activated carbon filter.

[0026] When the spray unit 4 sprays atomized water droplets into the air supply pipe 3, these atomized water droplets mix with the exhaust gas. After mixing, some water will fall along the air supply pipe 3, while some water will adhere to the inner wall of the air supply pipe 3. Since the exhaust gas contains paint with strong adhesion, the adhesion ability of the water mixed with the exhaust gas is enhanced, and some water will adhere to the inner wall of the air supply pipe 3 for a long time. More specifically, a cleaning unit is provided in one of the connecting pipes 7. The cleaning unit is used to remove the water droplets mixed with exhaust gas that adhere to the inner wall of the air supply pipe 3.

[0027] Specifically, the cleaning unit includes a cleaning roller 12, a cleaning drive unit 13 connected to the cleaning roller 12 and used to provide rotational thrust to the cleaning roller 12, and a cleaning lifting unit 14 connected to the cleaning drive unit 13. The cleaning lifting unit 14 is used to push the cleaning roller 12 into the air supply pipe 3 or pull the cleaning roller 12 out of the air supply pipe 3. The cleaning lifting unit 14 and the lifting device 9 can be electric telescopic rods, which allow the output end to move in a linear direction.

[0028] It should be noted that when the turntable 5 is in the filtering state, the connecting pipe 7 with the filtering unit is connected to the air supply pipe 3, and the filtering unit is used to filter and adsorb the exhaust gas. When the turntable 5 is in the cleaning state, the connecting pipe 7 with the cleaning unit is connected to the air supply pipe 3, and the cleaning unit removes water droplets adhering to the inner wall of the air supply pipe 3. It should also be noted that the turntable 5 has two connecting pipes 7. After the turntable 5 rotates 180 degrees in the forward direction, it needs to rotate 180 degrees in the reverse direction to complete the switching between the two connecting pipes 7. The two connecting pipes 7 are not of the same length and can be further divided into a filtering pipe and a cleaning pipe.

[0029] In order to enable the multiple connecting pipes 7 on the turntable 5 to connect with the air supply pipe 3 and complete the sealing work after the connection, an outer pipe 8 is provided at the end of the air supply pipe 3 away from the suction pipe 2. The outer pipe 8 is sleeved on the outside of the air supply pipe 3, and an upper sealing ring 11 for sealing is provided at the top of the outer pipe 8, and a lower sealing ring 10 for sealing is provided at the bottom of the outer pipe 8. A lifting device 9 for moving the outer pipe 8 up and down is provided at the outer pipe 8. A processing box 15 is provided at the paint booth 1, and the suction pipe 2 is inserted into the processing box 15.

[0030] In summary, this utility model embodiment provides a button-shaped paint booth structure with a waste gas recovery and treatment module. By setting a turntable 5 and other components at the bottom of the air supply pipe 3, the turntable 5 has two states: a filtering state and a cleaning state. When the turntable 5 is in the filtering state, the connecting pipe 7 with the filtering unit is connected to the air supply pipe 3, and the filtering unit is used to filter and adsorb the waste gas. When the turntable 5 is in the cleaning state, the connecting pipe 7 with the cleaning unit is connected to the air supply pipe 3, and the cleaning unit removes water droplets adhering to the inner wall of the air supply pipe 3. In this way, when the paint is being baked inside the paint booth 1, the waste gas inside can be drawn away, and the drawn-away waste gas is treated through two steps: atomization adsorption and filtration by the filtering unit, and then discharged after treatment, avoiding the waste gas being directly inhaled by the workers.

[0031] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
