Description

Technical Field

[0001] This application relates to the field of exhaust gas treatment technology in cosmetic bottle spraying, and in particular to a device that can automatically treat exhaust gas during cosmetic bottle spraying. Background Technology

[0002] Currently, in the cosmetics manufacturing industry, spraying cosmetic bottles is a common process. During this process, the spray gun sprays out a large amount of paint mist and volatile organic solvents. These substances not only harm the health of operators but also pollute the surrounding environment, seriously violating national laws and regulations on environmental protection. Therefore, how to effectively treat the waste gas generated during the spraying process has become one of the urgent problems to be solved in this industry.

[0003] The existing technologies and their drawbacks mainly include the following: electrostatic adsorption method, which has high equipment costs and complex maintenance; filter method, which requires regular replacement of filter materials and has high operating costs; water curtain method, which generates secondary pollution and requires further wastewater treatment; and biodegradation method, which has limited applicability and is not effective for certain high-concentration and difficult-to-degrade pollutants. Utility Model Content

[0004] The purpose of this invention is to solve or at least alleviate the problems existing in the prior art, such as the need for further wastewater treatment, the limited applicability of biodegradation methods, and the poor effectiveness for certain high-concentration and difficult-to-degrade pollutants.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for automatically treating waste gas during cosmetic bottle spraying, comprising a spraying chamber, wherein the spraying chamber is provided with a treatment mechanism for collecting and treating waste gas;

[0006] The processing mechanism includes an air suction pump fixedly installed on the spraying chamber. One end of the air suction pump is fixedly connected to an air suction pipe, and one end of the air suction pump is fixedly connected to an air outlet pipe. One end of the air outlet pipe is connected to a cyclone separator, and the output end of the cyclone separator is connected to a primary filter. An activated carbon adsorption tower and a catalytic combustion device are respectively provided on one side of the spraying chamber, and the activated carbon adsorption tower and the catalytic combustion device are connected through a conveying pipe. Two fan covers are symmetrically arranged inside the spraying chamber, and exhaust fan blades are rotatably installed inside both fan covers.

[0007] By adopting the above technical solution, the exhaust gas generated in the spraying chamber is transported to the cyclone separator through the exhaust pipe. Larger particles are thrown against the cylinder wall by centrifugal force and fall into the bottom collection box. The cleaned gas continues to flow upward and passes through the pre-filter, where fine particles are trapped. The preliminarily purified gas enters the activated carbon adsorption tower, where the organic solvents in the exhaust gas are adsorbed by the porous activated carbon, achieving a purification effect. Then, the adsorbed gas enters the catalytic combustion device, where the organic matter is oxidized and decomposed under the action of a catalyst through heating, and finally, clean air is discharged. This achieves efficient, low-cost, and comprehensive treatment of various harmful exhaust gases generated during the cosmetic bottle spraying process, significantly improving the safety and environmental protection of the production environment.

[0008] Optionally, one end of the suction pipe penetrates the top outer wall of the spray chamber and is provided with a gas collection hood, and the gas collection hood is located above the spray chamber.

[0009] By adopting the above technical solution, the gas collection hood can be set up to collect gas.

[0010] Optionally, the air collection hood is provided with multiple air guide plates for guiding.

[0011] Using the above technical solution, the airflow is guided to the pipeline through the air intake pipe and the air guide plate in the air collection hood.

[0012] Optionally, a filter plate for blocking dust is provided below the air collection hood.

[0013] By adopting the above technical solution, a filter plate can be installed to block dust.

[0014] Optionally, a support frame is fixedly installed on both sides of the gas collection hood, and a fixing column is fixedly installed on each of the two support frames. A positioning plate is sleeved on the fixing column, and a return spring is sleeved on the fixing column.

[0015] By adopting the above technical solution, a support frame can be set up to assist in the installation.

[0016] Optionally, a connecting plate is fixedly installed at one end of the fixed column, and the two ends of the reset spring are respectively fixedly installed on the outer walls of the positioning plate and the connecting plate on the side close to each other. The same synchronization plate is fixedly installed on both positioning plates, and a pull rod is fixedly installed on the bottom outer wall of the synchronization plate.

[0017] By adopting the above technical solution, the filter plate can block and filter impurities such as dust in the exhaust gas, preventing excessive dust from entering subsequent equipment and extending the service life of the equipment. By pulling the lever, the filter plate can be moved, which in turn moves the synchronous plate and the two positioning plates and compresses the return spring. At this time, the positioning installation of the filter plate can be released, allowing the filter plate to be clamped and replaced. This facilitates subsequent cleaning and maintenance, improving the convenience and flexibility of later use.

[0018] Optionally, a first mounting plate is fixedly sleeved on the air intake pipe, and a second mounting plate is fixedly installed on the air collection hood.

[0019] By adopting the above technical solution, the installation can be assisted by setting a first mounting plate and a second mounting plate.

[0020] Optionally, two slots are symmetrically provided on the second mounting plate, and a locking block is slidably installed in each of the two slots. Both locking blocks are fixedly connected to the first mounting plate. A positioning rod is slidably installed through the second mounting plate. Threads are provided on both outer surfaces of the positioning rod, and nuts are screwed onto both threads.

[0021] By using the above technical solution, the positioning rod can be removed by rotating the nuts and unscrewing both nuts, thereby releasing the installation and fixing of the first and second mounting plates, and thus allowing the gas collection hood to be disassembled.

[0022] In summary, the beneficial effects of this application are as follows:

[0023] 1. This invention employs an air pump and other devices to transport waste gas generated in the spraying chamber to a cyclone separator via an outlet pipe. Larger particles are thrown against the cylinder wall by centrifugal force and fall into the bottom collection box. The cleaned gas continues to flow upward and passes through a pre-filter, where fine particles are trapped. The pre-purified gas then enters an activated carbon adsorption tower, where the organic solvents in the waste gas are adsorbed by the porous activated carbon, achieving a purification effect. The adsorbed gas then enters a catalytic combustion device, where heating causes the organic matter to oxidize and decompose under the action of a catalyst, ultimately releasing clean air. This invention achieves efficient, low-cost, and comprehensive treatment of various harmful waste gases generated during the cosmetic bottle spraying process, significantly improving the safety and environmental friendliness of the production environment.

[0024] 2. In this application, the filter plate and other components work together to move the filter plate by pulling the lever. The movement of the lever will also move the synchronization plate and the two positioning plates, and compress the return spring. At this time, the positioning installation of the filter plate can be released, so that the filter plate can be clamped and replaced, which will facilitate cleaning and maintenance in the later stage and improve the convenience and flexibility of later use.

[0030] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0031] Please see Figure 1-3 A device for automatically treating waste gas generated during cosmetic bottle spraying includes a spraying chamber 1, a treatment mechanism installed on the spraying chamber 1 for collecting and treating waste gas, and an installation mechanism installed on the treatment mechanism. By setting up the treatment mechanism, the device achieves efficient, low-cost, and comprehensive treatment of various harmful waste gases generated during cosmetic bottle spraying, significantly improving the safety and environmental protection of the production environment.

[0032] The processing mechanism includes an air pump 2 fixedly installed on the spray chamber 1, an air intake pipe 8 fixedly connected to one end of the air intake port of the air pump 2, an air outlet pipe 9 fixedly installed at one end of the air outlet of the air pump 2, and a cyclone separator 3 connected to one end of the air outlet pipe 9, a primary filter 4 connected to the output end of the cyclone separator 3, an activated carbon adsorption tower 5 and a catalytic combustion device 7 respectively provided on one side of the spray chamber 1, and the activated carbon adsorption tower 5 and the catalytic combustion device 7 are connected by a conveying pipe 6, two fan covers 11 symmetrically arranged in the spray chamber 1, exhaust fan blades 12 rotatably installed in the two fan covers 11, a gas collection hood 10 provided at one end of the air intake pipe 8, and the gas collection hood 10 is located above the spray chamber 1, and multiple air guide plates 21 are provided in the gas collection hood 10 for guiding.

[0033] During operation, the suction pump 2 is started. The suction pump 2 guides the airflow through the suction pipe 8 and the air guide plate 21 inside the gas collection hood 10, directing the exhaust gas generated in the spray booth 1 to the cyclone separator 3 via the exhaust pipe 9. Larger particles are thrown against the cylinder wall by centrifugal force and fall into the bottom collection box. The cleaned gas continues to flow upwards, passing through the pre-filter 4, where fine particles are trapped. The pre-purified gas then enters the activated carbon adsorption tower 5, where the organic solvents in the exhaust gas are adsorbed by the porous activated carbon, achieving a purification effect. The adsorbed gas then enters the catalytic combustion device 7, where heating causes the organic matter to oxidize and decompose under the action of a catalyst, ultimately releasing clean air. This achieves efficient, low-cost, and comprehensive treatment of various harmful exhaust gases generated during cosmetic bottle spraying, significantly improving the safety and environmental friendliness of the production environment.

[0034] The automated control system reduces manual intervention, improves production efficiency, lowers operating costs, solves the secondary pollution problem existing in the current technology, and ensures that the treated exhaust gas meets national emission standards and environmental protection regulations. The spray booth 1 is equipped with a control system consisting of a PLC controller, sensors, and actuators, which is responsible for monitoring and adjusting the operating status of the entire system. The PLC controller adjusts parameters such as fan speed and valve opening based on the data fed back by the sensors to ensure stable and reliable treatment results.

[0035] Reference Figure 2-4The installation mechanism includes a filter plate 13 located below the air collection hood 10 and used to block dust, two support frames 14 fixedly installed on both sides of the air collection hood 10, two fixing columns 16 fixedly installed on the two support frames 14, a positioning plate 18 sleeved on the fixing column 16, a return spring 17 sleeved on the fixing column 16, a connecting plate 15 fixedly installed at one end of the fixing column 16, and the two ends of the return spring 17 are respectively fixedly installed on the outer wall of the positioning plate 18 and the connecting plate 15 on the side close to each other, a same synchronization plate 19 fixedly installed on the two positioning plates 18, a pull rod 20 fixedly installed on the bottom outer wall of the synchronization plate 19, a first mounting plate 22 fixedly sleeved on the suction pipe 8, and a second mounting plate 23 fixedly installed on the air collection hood 10.

[0036] The installation mechanism also includes two slots 24 symmetrically opened on the second mounting plate 23, two blocks 25 slidably installed in the two slots 24, both blocks 25 being fixedly connected to the first mounting plate 22, a positioning rod 26 penetrating and slidably installed on the second mounting plate 23, two threads 27 opened on the outer surfaces of both sides of the positioning rod 26, and two nuts 28 screwed onto the two threads 27.

[0037] In use, the filter plate 13 can block and filter dust and other impurities in the exhaust gas, preventing excessive dust from entering subsequent equipment and extending the service life of the equipment. By pulling the lever 20, the filter plate 13 can be moved, which in turn moves the synchronous plate 19 and the two positioning plates 18, compressing the return spring 17. At this time, the positioning installation of the filter plate 13 can be released, allowing the filter plate 13 to be clamped and replaced, which facilitates later cleaning and maintenance, improving the convenience and flexibility of later use. By turning the nuts 28 and unscrewing them, the positioning rod 26 can also be removed, thereby releasing the installation and fixation of the first mounting plate 22 and the second mounting plate 23, and thus allowing the gas collection hood 10 to be disassembled.

[0038] The implementation principle of this application is as follows: When the spraying operation begins, the suction pump 2 is started. The suction pump 2 guides the airflow to the pipeline through the suction pipe 8 and the air guide plate 21 in the gas collection hood 10. The waste gas generated in the spraying chamber 1 is transported to the cyclone separator 3 through the exhaust pipe 9. Larger particles are thrown to the cylinder wall by centrifugal force and fall into the bottom collection box. The cleaned gas continues to flow upward. The cleaned gas passes through the primary filter 4, where fine particles are intercepted. The preliminarily purified gas enters the activated carbon adsorption tower 5, where the organic solvents in the waste gas are adsorbed by the porous activated carbon, achieving a purification effect. Then, the adsorbed gas enters the catalytic combustion device 7, where the organic matter is oxidized and decomposed under the action of the catalyst through heating, and finally clean air is discharged. This achieves efficient, low-cost, and comprehensive treatment of various harmful waste gases generated during the cosmetic bottle spraying process, significantly improving the safety and environmental protection of the production environment.

[0039] The automated control system reduces manual intervention, improves production efficiency, lowers operating costs, solves the secondary pollution problem existing in the current technology, and ensures that the treated exhaust gas meets national emission standards and complies with environmental protection regulations.

[0040] By setting up the filter plate 13, dust and other impurities in the exhaust gas can be blocked and filtered, preventing excessive dust from entering subsequent equipment and improving the service life of subsequent equipment. By pulling the pull rod 20, the filter plate 13 can be moved, which in turn moves the synchronous plate 19 and the two positioning plates 18, and compresses the return spring 17. At this time, the positioning installation of the filter plate 13 can be released, so that the filter plate 13 can be clamped and replaced, which facilitates later cleaning and maintenance, and improves the convenience and flexibility of later use. By turning the nuts 28 and turning them down, the positioning rod 26 can also be removed, which releases the installation and fixation of the first mounting plate 22 and the second mounting plate 23, so that the gas collection hood 10 can be disassembled.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
