Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of environmental protection treatment of paint mist, and in particular relates to a composite paint mist treatment device. Background Art
[0002] In the manufacturing industry, products such as industrial parts need to be painted. The paint surface of industrial products is formed by spraying paint. The formation of the paint surface can not only beautify the product, but also protect the product. For example, an anti-oxidation protective layer is formed on the surface of the product by spraying paint.
[0003] During the painting process, a large amount of highly polluting, irritating and toxic paint mist is easily generated. Therefore, the paint mist generated by the spraying operation needs to be treated in an environmentally friendly manner. Through environmentally friendly treatment methods, we can firstly avoid serious environmental pollution caused by paint mist, secondly avoid paint mist being harmful to the health of construction workers, and thirdly, achieve green production and processing through environmentally friendly treatment of paint mist.
[0004] At present, the more conventional treatment method is to treat the paint mist through a traditional dry paint mist treatment device, such as directly using physical adsorption to treat the paint mist generated by work, such as using adsorption devices such as activated carbon. However, the treatment effect of this treatment method is not ideal. Specifically, the amount of paint mist generated by the work is large, and as the physical adsorbent becomes saturated with adsorption, it will lose its adsorption effect. The large amount of paint mist generated by the work can saturate the adsorption device in a short time, and its effective working time is too short. Utility Model Content

[0038] Example 1
[0039] like Figure 1-5 As shown, a composite paint mist treatment device includes a centrifugal separation component 1, a water cyclone separation component 2, a paint residue separation component 3, and an exhaust gas treatment component 4.
[0040] The centrifugal separation component 1 includes a centrifugal fan 101 and an airflow converger 102 integrally formed on the casing of the centrifugal fan 101. The airflow converger 102 is a funnel-shaped structure, and the large end of the airflow converger 102 is connected to the airflow outlet of the centrifugal fan 101. The advantage of the funnel-shaped design is that during operation, when the paint mist is sucked into the centrifugal fan 101 under negative pressure, it is initially separated and discharged into the airflow converger 102. On the one hand, the airflow converger 102 gathers the paint mist for easy discharge, and on the other hand, increases the discharge speed of the paint mist, so that the paint mist can enter the subsequent water cyclone separation component at a sufficient speed. In this way, the processing efficiency is improved.
[0041] The water cyclone separation component includes a water ring vacuum pump 201 , a water replenishing tank 202 , an air inlet pipe 203 , a water inlet pipe 204 and a water outlet pipe 205 .
[0042] Specifically, the water outlet of the water replenishment tank 202 is connected to the water inlet of the water ring vacuum pump 201 by a pipe, and the pipe interface is fixed with a clamp. The outlet of the centrifugal fan 101 is connected to the airflow collector 102 by screws, and the airflow collector 102 is connected to the air inlet of the water ring vacuum pump 201 through the air inlet pipe 203, and the pipe interface is fixed with a clamp; the outlet of the water ring vacuum pump 201 is connected to the inlet of the paint residue separation water tank 301 described below through the water outlet pipe 205.
[0043] The paint residue separation assembly includes a paint residue separation water tank 301 , a coagulant hopper 302 , a coagulant discharge port 303 , a solenoid valve 304 , a water level sensor 305 , a paint residue plate frame 306 , a circulating water pump 307 and a circulating water pipe 308 .
[0044] Specifically, the paint residue separation water tank 301 is a U-shaped box structure with a hollow interior, and includes a top plate, a bottom plate, a left plate, a right plate, a front plate, and a rear plate. The coagulant hopper 302 is fixedly mounted on the top plate of the paint residue separation water tank 301 .
[0045] At the same time, a coagulant discharge port 303 is installed at the lower end of the coagulant hopper 302. The coagulant discharge port 303 is a tubular structure, and the coagulant discharge port 303 passes through the through hole of the top plate of the paint residue separation water tank 301 (a solenoid valve 304 for controlling the discharge is installed on the coagulant discharge port 303). During the working process, the coagulant for coagulating the paint is fed from the coagulant hopper 302 and discharged into the paint residue separation water tank 301, and the paint liquid in the paint residue separation water tank 301 is coagulated into paint residue, which is convenient for separation and water recycling.
[0046] The paint residue plate frame 306 is a flat plate structure, and a plurality of mesh holes are formed on the paint residue plate frame 306 . The paint residue plate frame 306 is installed at the following positions: the paint residue plate frame 306 is fixedly assembled in the slideways of the left and right plates of the paint residue separation water tank 301 .
[0047] The above-mentioned circulating water pump 307 is assembled and connected to the water inlet of the water replenishment tank 202 (the outlet of the circulating water pump 307 is connected to the water inlet of the water replenishment tank 202 by a circulating water pipe 308). Specifically, the water outlet end of the circulating water pump 307 is connected to one end of the circulating water pipe 308, and the other end of the circulating water pipe 308 is located in the water replenishment tank 202.
[0048] During the working process, the water from the separated paint residue is pumped into the water replenishment tank 202 through the circulating water pump 307 to achieve the recycling of water.
[0049] The above-mentioned waste gas treatment component includes a waste gas treatment pipe waste gas treatment pipe 401; the waste gas treatment pipe waste gas treatment pipe 401 is a tubular structure, and the waste gas treatment pipe waste gas treatment pipe 401 is connected to the paint residue separation water tank 301.
[0050] During operation, the waste gas in the paint residue separation water tank 301 is treated and then discharged through the waste gas treatment pipe. Specifically, the lower part of the waste gas treatment pipe 401 in the waste gas treatment assembly 4 is directly inserted into the top plate of the paint residue separation water tank 301, and the connection is sealed with glass glue. At the same time, the waste gas treatment pipe 401 is fixedly assembled with activated carbon 403, filter cotton 404, and catalytic tube 402.
[0051] The fixed position point where the composite paint mist treatment device is installed is set indoors. Generally, the air inlet of the centrifugal fan 101 is directly opposite to the rear of the paint mist spraying equipment, so that the paint mist can be absorbed and treated immediately. The equipment is easy to install and can be carried by workers in pairs or directly by forklift. The equipment is placed flat on the ground and Figure 1 After the orientation is correct, tighten the pipes and clamps between each part to complete the installation and operation.
[0052] Example 2
[0053] like Figure 1-5 As shown, the composite paint mist treatment device also includes an electric control system 5 for controlling the centrifugal separation component 1, the water cyclone separation component 2, the paint residue separation component 3, and the exhaust gas treatment component 4, wherein the electric control component is a conventional electric control system disclosed in the prior art, which mainly includes a controller and a power supply, wherein the controller is a conventional controller disclosed in the prior art, which is used to control the centrifugal fan 101, the water ring vacuum pump 201, the circulating water pump 307, the solenoid valve 304, and the water level sensor 305. Those skilled in the art can refer to the technical manual or dictionary or the specific working principle, control method, and specific structure of the electric control system 5 disclosed in the utility model.
[0054] Example 3
[0055] like Figure 1-5 As shown, as another embodiment of the utility model, a rubber band is provided at the bottom of the bag-type gas collector at the top of the exhaust gas treatment pipe 401 to ensure the sealing and fixation between the bag-type gas collector and the ventilation pipe, and a steel wire braided layer is provided inside the ventilation pipe, and the catalytic tube 402, activated carbon 403 and filter cotton 404 are placed on the steel wire braided layer from bottom to top in sequence to prevent the paint mist purification and adsorption effect from being reduced or unstable due to the displacement of the filter layer.
[0056] The specific implementation process is: when the spraying operation generates paint mist, the centrifugal fan 101 is started by the controller, and the negative pressure generated by the inlet of the centrifugal fan 101 sucks the paint mist into the machine; the larger paint droplets in the paint mist will be thrown into the shell of the centrifugal fan 101 due to the rotating centrifugal action of the centrifugal fan 101 blades, thereby achieving partial separation of the paint mist.
[0057] The remaining paint mist enters the water ring vacuum pump 201 through the outlet of the centrifugal fan 101 and the airflow converger 102. After the water ring vacuum pump 201 absorbs water from the water supply tank 202, most of the paint droplets in the paint mist can be adsorbed in water through the water washing method to achieve separation. The gas-liquid mixture generated by the paint mist after water washing is discharged into the paint residue separation water tank 301 through the water ring vacuum pump 201.
[0058] A coagulant bucket 302 is installed on the top plate of the paint residue separation water tank 301. There is a paint coagulant inside the coagulant bucket 302. The controller controls the opening and closing of the coagulant bucket 302 through the solenoid valve 304; adding a coagulant to the paint residue separation water tank 301 can coagulate the paint in the water, and the water filtered by the two layers of paint residue plate frames 306 is pumped into the water replenishment tank through the circulating water pump 307, realizing the circulation of water for paint mist washing; the two layers of paint residue plate frames 306 can be alternately extracted to clean the paint residue condensed on the surface.
[0059] A catalytic tube 402, activated carbon 403 and filter cotton 404 are installed in the exhaust gas treatment pipe 401. The exhaust gas in the paint residue separation water tank 301 is treated through the exhaust gas treatment pipe 401 and then discharged. The activated carbon 403 and filter cotton 404 are used to absorb the remaining paint droplet particles in the exhaust gas, and the catalytic tube 402 is used to catalytically decompose harmful gases in the exhaust gas.
[0060] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
