Description

Technical Field

[0001] This utility model specifically relates to the field of electrophoresis production line technology, and more specifically to an electrophoresis production line with waste gas treatment function. Background Technology

[0002] Electrophoresis can give mechanical parts a uniform, smooth surface coating with a certain gloss. This coating can improve the appearance quality of the parts, making them more aesthetically pleasing. Different electrophoretic paint formulations can produce different color effects to meet the appearance requirements of product design. For example, after electrophoretic treatment, the casing parts of some electronic products and hardware furniture accessories have a uniform color and good texture, enhancing the visual appeal of the products.

[0003] Chinese Patent Publication No. CN 115595648 A discloses a workpiece transfer device and an electrophoresis production line, belonging to the technical field of electrophoresis production lines. It includes a transport frame, with a base plate fixedly connected to the bottom of the transport frame, a first mounting plate fixedly connected to the top of the outer surface of the transport frame, a second mounting plate fixedly connected to the top of the outer surface of the first mounting plate, and a first motor fixedly mounted on one side of the outer surface of the first mounting plate.

[0004] Electrophoretic paint is typically composed of resins, pigments, and solvents. During the electrophoresis process, especially when the electrophoresis bath temperature is high and the paint solution is circulated and stirred, solvents will evaporate. These solvents are mainly organic solvents, such as alcohols, ketones, and esters. For example, commonly used electrophoretic paint solvents may include butanol and methyl isobutyl ketone. These organic solvents evaporate into the air, forming organic waste gases.

[0005] The electrophoresis production line in the aforementioned patent cannot collect and treat the waste gas generated during electrophoresis, resulting in the waste gas spreading throughout the workshop. Utility Model Content

[0006] The purpose of this utility model is to provide an electrophoresis production line with waste gas treatment function, which can collect and treat waste gas during the electrophoresis of parts, thereby reducing the spread of waste gas and improving the cleanliness of the workshop air; so as to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An electrophoresis production line with exhaust gas treatment function includes two symmetrically arranged gantry steel frames. The two gantry steel frames are fixed to the ground by anchor bolts, and multiple overhead cranes are installed on the two gantry steel frames. Each overhead crane hangs a component for electrophoresis treatment of parts.

[0009] Multiple electrophoresis units are installed below each gantry steel frame; each electrophoresis unit is equipped with a gas collection hood; the gas collection hood is connected to the main pipe through an exhaust pipe, wherein the main pipe is connected to an air purifier;

[0010] Each electrophoresis assembly is equipped with an electrophoresis solution filtration device on its outer side.

[0011] As a further technical solution of this utility model, the electrophoresis assembly includes an electrophoresis pool; a first cleaning pool and a second cleaning pool are provided on one side of the electrophoresis pool.

[0012] As a further technical solution of this utility model, the electrophoresis liquid filtration device includes a filtration component, one end of which is connected to the electrophoresis pool and the other end of which is connected to the inlet end of the circulation pump; the outlet end of the circulation pump is connected to the electrophoresis pool through a return pipe.

[0013] As a further technical solution of this utility model, at least one circulating pump is provided, which is fixed on a bracket; a controller is also fixed on the bracket; the controller is electrically connected to the circulating pump.

[0014] As a further technical solution of this utility model, the filter assembly includes a liquid extraction pipe, which is connected to a three-way ball valve, and the other two valve ports of the three-way ball valve are connected to the liquid inlet of the filter through two first connecting pipes; the liquid outlet of the filter is connected to another three-way ball valve through a second connecting pipe, and a manifold is also connected to the three-way ball valve.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In use, multiple overhead cranes suspend the parts to be electrophoretically coated via hangers, and then cooperate with the electrophoresis assembly below to achieve electrophoretic treatment of the parts. During the process, the electrophoretic liquid, composed of resin, pigments, solvents, and other components, will generate a certain amount of waste gas. At this time, the air purifier is turned on, and the built-in fan will generate a suction force on the main pipe.

This is used to maintain the uniformity and cleanliness of the electrophoretic solution, prevent impurities in the paint from depositing on the surface of the parts, and avoid defects on the surface of the electrophoretic product parts.

[0018] 3. In this utility model, the filter assembly is equipped with two filters, and a three-way ball valve is provided at both ends of the two filters. The flow direction of the electrophoresis liquid can be controlled by the three-way ball valve. When one filter is working, the other filter can be disassembled and cleaned.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-7 In this embodiment of the utility model, an electrophoresis production line with waste gas treatment function includes two symmetrically arranged gantry steel frames 1. The two gantry steel frames 1 are fixed to the ground by anchor bolts, and multiple overhead cranes 2 are installed on the two gantry steel frames 1. Each overhead crane 2 is equipped with a hanging device for electrophoresis treatment of parts.

[0032] Multiple sets of electrophoresis components 3 are provided below each gantry steel frame 1; each electrophoresis component 3 is provided with a gas collection hood 4; the gas collection hood 4 is connected to the main pipe 6 through the exhaust pipe 5, wherein the main pipe 6 is connected to the air purifier 7.

[0033] Each electrophoresis assembly 3 is equipped with an electrophoresis solution filtration device 8 on its outer side.

[0034] By adopting the above technical solution, during use, multiple overhead cranes 2 suspend the parts to be electrophoretically treated via hangers, and then cooperate with the electrophoresis assembly 3 below to achieve electrophoretic treatment of the parts. During the treatment process, the electrophoresis liquid composed of resin, pigment, solvent and other components will generate a certain amount of waste gas. At this time, the air purifier 7 is turned on, and the built-in fan will generate a suction force on the main pipe 6. The waste gas is collected in the gas collection hood 4, and then enters the air purifier 7 through the exhaust pipe 5 and the main pipe 6 for purification treatment. This effectively reduces the direct emission of waste gas and improves the air quality of the production line.

[0035] In this embodiment, the electrophoresis assembly 3 includes an electrophoresis pool 31; a first cleaning pool 32 and a second cleaning pool 33 are provided on one side of the electrophoresis pool 31.

[0036] After electrophoresis, some undeposited electrophoretic paint may remain on the surface of the metal parts. If not cleaned, this excess paint may form defects such as runs and particles on the surface of the parts after drying.

[0037] Therefore, a first cleaning pool 32 and a second cleaning pool 33 are provided on one side of the electrophoresis pool 31, so that the metal parts after electrophoresis can be cleaned twice. The cleaning can ensure that excess paint is removed and that the size of the parts meets the design requirements.

[0038] In this embodiment, the electrophoresis solution filtration device 8 includes a filter component 81, one end of which is connected to the electrophoresis pool 31 and the other end is connected to the inlet end of the circulation pump 82; the outlet end of the circulation pump 82 is connected to the electrophoresis pool 31 through a return pipe 85.

[0039] More specifically, at least one circulating pump 82 is provided, which is fixed on a bracket 83; a controller 84 is also fixed on the bracket 83; the controller 84 is electrically connected to the circulating pump 82.

[0040] By adopting the above technical solution, during the electrophoresis process of the parts, the circulating pump 82 draws the electrophoretic liquid in the electrophoretic pool 31. The electrophoretic liquid first enters the filter assembly 81 for filtration, and then flows back to the electrophoretic pool 31 through the return pipe 85. This is used to maintain the uniformity and cleanliness of the electrophoretic solution, prevent impurities in the paint from depositing on the surface of the parts, and avoid defects on the surface of the electrophoretic product parts.

[0041] In this embodiment, the filter assembly 81 includes a liquid extraction pipe 811, which is connected to a three-way ball valve 812. The other two valve ports of the three-way ball valve 812 are connected to the inlet end of the filter 814 through two first connecting pipes 813. The outlet end of the filter 814 is connected to another three-way ball valve 812 through a second connecting pipe 815. A manifold 816 is also connected to the three-way ball valve 812.

[0042] By adopting the above technical solution, the filter assembly 81 is equipped with two filters 814, and a three-way ball valve 812 is provided at both ends of the two filters 814. The flow direction of the electrophoresis liquid can be controlled by the three-way ball valve 812. When one filter 814 is working, the other filter 814 can be disassembled and cleaned. Alternating operation can avoid the situation where the filter cannot be used normally due to unexpected failure.

[0043] The working principle of this utility model is as follows: During use, multiple overhead cranes 2 suspend the parts to be electrophoretically coated via hangers, and then cooperate with the electrophoresis assembly 3 below to achieve electrophoretic treatment of the parts. During the process, the electrophoretic liquid composed of resin, pigment, solvent and other components will generate a certain amount of waste gas. At this time, the air purifier 7 is turned on, and the built-in fan will generate a suction force on the main pipe 6. The waste gas is collected in the gas collection hood 4, and then enters the air purifier 7 through the exhaust pipe 5 and the main pipe 6 for purification. This effectively reduces the direct emission of waste gas and improves the air quality of the production line. During the electrophoresis process of the parts, the circulating pump 82 draws the electrophoretic liquid in the electrophoretic pool 31. The electrophoretic liquid will first enter the filter assembly 81 for filtration, and then flow back to the electrophoretic pool 31 through the return pipe 85. This is used to maintain the uniformity and cleanliness of the electrophoretic solution, prevent impurities in the paint from depositing on the surface of the parts, and avoid defects on the surface of the electrophoretic product parts.

[0044] The filter assembly 81 is equipped with two filters 814, and a three-way ball valve 812 is provided at both ends of the two filters 814. The flow direction of the electrophoresis liquid can be controlled by the three-way ball valve 812. When one filter 814 is working, the other filter 814 can be disassembled and cleaned. Alternating operation can avoid the situation where the filter cannot be used normally due to unexpected failure.
