Description

electrophoresis system with side overflow

technical field

The utility model relates to an electrophoresis system, in particular to an electrophoresis system achieved by using a side overflow system.

Background technique

With the improvement of living standards, consumers pay more and more attention to the appearance of products, and products with brightly colored shells can often become a selling point that surpasses similar products, leading the industry to start to incorporate the appearance of products into the focus of design. Generally speaking , the shell of the product usually includes multiple workpieces, and the industry needs to paint each workpiece separately, and then assemble the workpieces to become a finished product. The process of coloring the workpieces is to use spraying, but this method It is to use artificial coloring on the workpiece, which will lead to low production efficiency, and the industry needs to pay too high production costs in terms of manpower. Therefore, some operators have begun to use electrode-position coating (Electrode-position coating) to replace traditional spraying. The way it is colored.

Generally speaking, the electrocoating method is very similar to the electroplating process, both of which belong to the electrodeposition process (Electrode position process), that is, to use the electrode plate to pass current to make the solid matter (metal, paint...) contained in the solvent adhere to the On the surface of an object, the purpose of which is to change the character, size or color of the surface of the object. In the early days, in the process of electro-coating, the industry usually used a comprehensive overflow system. Please refer to Figure 1. The industry first mixed the electro-coating paint evenly in the solvent to form an electro-coating liquid, and injected the electro-coating liquid into a In the main tank 10, the operator will immerse the workpiece 12 to be colored in the main tank 10, and pass direct current on the electrode plates 104 provided at the two ends of the main tank 10, so that the paint in the electrolytic solution can adhere On the workpiece 12, due to the continuous process of electrification, the paint contained in the electrophoresis solution will gradually decrease, and the electrophoresis solution will also be mixed with impurities in the working environment (such as: dust, hair, etc.) ), which in turn affects the quality of the subsequent workpiece 12. Therefore, the industry injects new electrolytic liquid through the pipeline (not shown) laid at the bottom of the main tank, and as the water level increases, the old electrolytic liquid will overflow. Flow into the overflow tank 11 located next to the main tank 10, and flow out through the overflow tank 11, so that the industry can keep the workpiece 12 in the process of electrification, and still maintain a uniform color, and the overall overflow Streaming systems have the following disadvantages:

1. The workpieces 12 are placed on both ends of the main tank 10 adjacent to the electrode plate 104, so that the operator can only place two workpieces 12 in the main tank 10 for each operation, which affects the production efficiency of the operator. If the operator wants to increase the production capacity , then a comprehensive overflow system with a larger main tank 10 must be purchased, resulting in more production costs for the industry.

2. When the industry wants to use a comprehensive overflow system with a larger main tank 10, more workshop space must be planned to place the comprehensive overflow system, resulting in the need to change the placement of other instruments and equipment or expand the workshop. As a result, the industry needs to bear more investment costs.

In order to improve the above shortcomings, some operators changed the direction of the workpiece 12 and the electrode plate 104 of the comprehensive overflow system to the direction of the workpiece 22 and the electrode plate 204 in Figure 2, and this arrangement caused the overflow of the electrolytic solution. The flow direction (as shown by the arrow in Figure 1) is perpendicular to the workpiece 12. Generally speaking, the workpiece 12 is usually provided with openings (screw holes, decorative holes, etc.), and when the electrophoresis liquid suddenly flows into the narrow opening, the opening The phenomenon of reverse flow is likely to occur near the entrance, resulting in inconsistent paint thickness near the opening and other parts of the workpiece 12. Therefore, although this method can increase the production capacity, new problems arise.

Therefore, the industry has developed a side overflow system, please refer to shown in Figure 2, the shorter end of the main tank 20 is provided with a first overflow port 200, in addition, the longer side of an overflow tank 24 and this The longer side of the main tank 20 is connected, and the corresponding other side is connected with a recovery tank 26, and one end of the overflow tank 24 adjacent to the first overflow port 200 is provided with a second overflow port 240 , In this way, the electrolyzed liquid in the main tank 20 can flow into the overflow tank 24 through the first and second overflow ports 200, 240 in sequence (as shown by the arrow), and pass through the overflow tank 24 flows away from one end of the second overflow port 240, so the electrode plates 204 can be arranged on the longer sides of the main groove 20, and the workpiece 22 can also be placed between the two electrode plates 204, so as to avoid the The workpiece 22 is perpendicular to the flow direction of the electro-deposited liquid, and the resulting reverse flow phenomenon. In addition, in order to reduce production costs, the industry usually re-injects part of the electro-deposited liquid flowing out of the overflow tank 24 into the main tank after filtering impurities. 20, another part of the electrolytic solution will be decomposed into reclaimed paint and reclaimed solvent, and respectively injected into the overflow tank 24 and the recovery tank 26 in sequence, and the recovery solvent in the recovery tank 26 will be It flows into the overflow tank 24 through a through hole 260 (as shown by the arrow), so that the recovered paint and solvent can be mixed again, and then injected into the main tank 20 for powering the process.

In the above-mentioned side overflow system, because the length of the overflow tank 24 is too long, the electrophoresis liquid stays in the overflow tank 24 for a long time, so that the paint contained in the electrophoresis liquid is easy to settle on the overflow tank 24 Bottom, in addition, in order to avoid the electrophoresis in the overflow tank 24, it is poured into the recovery tank 26, and the through hole 260 is located on the electrophoresis level higher than the overflow tank 24, so the recovered solvent When flowing into the overflow tank 24 through the through hole 260, due to the relatively light specific gravity of the solvent itself, it cannot be completely mixed with the paint at the bottom, so that the electrophoresis liquid in the overflow tank 24 produces a layering effect (that is, the paint and the solvent are delaminated. ), and then when it is injected into the main tank 20, it affects the concentration of the electrophoresis in the main tank 20, resulting in uneven color or color layering of the workpiece 22.

In view of the problem of uneven color caused by the above-mentioned side overflow system, the product failure rate is higher than that of the full overflow system, so that the industry must make a choice between production capacity and product qualification rate. Therefore, the designer has made long-term research And experiments, and finally developed and designed the side overflow electrodeposition system of the present utility model, in order to effectively solve the aforementioned problems and achieve the effect of both production capacity and product qualification rate.

Detailed ways

A kind of electroplating system of side overflow that the utility model proposes, please refer to shown in Fig. 3, comprise a main tank 30, an overflow tank 34 and a recovery tank 36, and this main tank 30, overflow tank 34 and The recovery tanks 36 are all rectangular grooves respectively. The longer side on the overflow tank 34 is connected to the longer side on the main tank 30, and the corresponding other side is connected to the recovery tank 36. The longer side of the upper side is connected, wherein the main tank 30 is respectively arranged with a plurality of pipelines along its longitudinal direction to provide the electrolytic liquid in the main tank 30. In a preferred embodiment of the present invention , is to be provided with four pipelines such as the first pipeline 301, the second pipeline 302, the third pipeline 303 and the fourth pipeline 304 in the main tank 30 as an example, for illustration, please refer to Fig. 3 again , the two sides of the main tank 30 with longer sides are respectively provided with an electrode plate 31, and the side with the shorter side of the main tank 30 is provided with a first overflow port 300. When the electro-deposition liquid is injected into the main tank 30 and reaches a workable height, the operator can immerse the workpieces to be colored in batches into the electro-deposition liquid to carry out the process of electro-deposition coating.

3 and 4, the overflow tank 34 is adjacent to the first overflow port 300 and is provided with a second overflow port 340 on the shorter side, and the second overflow port 340 and The first overflow port 300 is connected, and when the electrospray in the main tank 30 rises to a height exceeding the first overflow port 300, the electrospray will flow into the first overflow port 300, and Flow through the second overflow port 340 into the overflow tank 34 to prevent the electrophoresis liquid in the main tank 30 from overflowing out of the main tank 30. A partition 344 is arranged in the overflow tank 34 along its transverse direction. The overflow tank 34 is divided into a first overflow unit 341 and a second overflow unit 342, and the electroplating solution flows into the first overflow unit 341 from the second overflow port 340, and exceeds the dividing plate 344 at its height When the height is high, overflow from the first overflow unit 341 to the second overflow unit 342, wherein the partition 344 is also provided with a filter screen 346, and the filter screen 346 can convectively flow into the second overflow unit 342 For the first filtering of impurities, the electrophoretic liquid will flow out from the bottom of the second overflow unit 342 at the end far away from the partition plate 344 into a filter 51, and the impurity filtration process for the electrophoretic fluid will be completed. Afterwards, a part of the recovered electrolyzing fluid will flow into a temperature control device 52, and after maintaining this part of the recovered electrolyzing fluid at an operating temperature, it passes through the first, second, third and fourth pipelines 301, 302, and 303 respectively. , 304 are re-injected into the main tank 30, and re-injected into the first overflow unit 341 through a filter pipe 347, and another part of the recovered electrolytic solution will flow into an ultra-filter (Ultra-filtration, referred to as UF) 53 , and be decomposed into recovered paint and recovered solvent, wherein the recovered paint will flow into the first overflow unit 341 through a paint recovery pipe 348, and the recovered solvent will flow into the recovery tank through a solvent recovery pipe 362 within 36.

Furthermore, please refer to FIGS. 3 and 4 again, the first overflow unit 341 is provided with a through hole 360 on the side adjacent to the second overflow port 340 and connected with the recovery tank 36, so that the first overflow unit 341 The overflow unit 341 communicates with the recovery tank 36, and an L-shaped sinking tube 345 is arranged adjacent to the through hole 360, so that the recovered solvent in the recovery tank 36 passes through the through hole 360 and The sinking tube 345 flows into the bottom of the first overflow unit 341. From the above, it can be seen that the first overflow unit 341 will be injected with four different concentrations of electrophoretic fluid during the electro-coating process, including The main tank 30 electrodeposited liquid that flows in from the second overflow port 340, the reclaimed electrolyzed liquid that flows in through the filter pipe 347, the reclaimed paint that flows in through the paint recovery pipe 348, and the solvent that flows in through the bottom pipe 345 are reclaimed. In contrast, the recovered solvent has the lightest specific gravity, while the recovered paint has the heaviest specific gravity, as shown in Figure 5, so when the recovered solvent is injected into the bottom of the first overflow unit 341 through the sinking tube 345, it will Go up because of its relatively light specific gravity (as shown by the arrow in the figure), and when the recovered paint will be injected into the upper layer of the first overflow unit 341 through the paint recovery pipe 348, it will go down because of its relatively heavy specific gravity. Therefore, a circulation is formed, and the electrophoretic liquid in the first overflow unit 341 can be evenly mixed.

3 and 4 again, the second overflow unit 342 is provided with a pumping motor 501 outside the end far away from the separator 344, which is used to charge the liquid in the second overflow unit 342. It is pumped into the filter 51 so that the rate at which the electrophoretic liquid flows out of the second overflow unit 342 is higher than the rate at which the electrophoretic fluid flows into the first overflow unit 341, so that the second overflow unit The horizontal liquid level of the electrolyzed liquid in 342 is lower than the horizontal liquid level of the electrolyzed liquid in the first overflow unit 341, and produces an approximate waterfall effect, so that when the electrolyzed liquid flows into the second overflow unit 342, it can Mix further to avoid the phenomenon of coating and solvent stratification. Moreover, in other embodiments of the present utility model, the first overflow unit 341 is also provided with a pure water pipe 349, and the pure water pipe 349 mainly functions as Overflow compensation, that is, to maintain the flow of the first overflow unit 341 overflowing to the second overflow unit 342, so as to prevent the second overflow unit 342 from causing the first overflow unit 341 to overflow due to its low water level. When overflowing to the second overflow unit 342 , too many air bubbles are generated, so that the electrodeposition liquid mixed with air bubbles is re-injected into the main tank 30 , resulting in uneven color on the workpiece.

Furthermore, referring to Fig. 4 again, the recovery tank 36 is adjacent to the solvent recovery pipe 362 and is provided with an extraction pipe 366, and the extraction pipe 366 passes through a water pump 502 and a first balance pipe 367 and a second balance pipe 368. wherein, the first balance pipe 367 is arranged at the end of the recovery tank 36 away from the extraction pipe 366, and the second balance pipe 368 is arranged at the middle part of the recovery tank 36, when the recovered solvent passes through the solvent recovery pipe 362 flows into the recovery tank 36, due to the operation of the water pump 502, part of the recovered solvent flows into the extraction pipe 366, and flows out through the first and second balance pipes 367, 368, so that the recovered solvent can be recovered The concentration of the solvent in each part of the tank 36 is maintained at a fixed value, so as to avoid the solvent concentration at both ends of the recovery tank 36 being different due to the excessive size of the recovery tank 36 .

Referring back to Figures 3 and 4, the first pipeline 301 is located at one end adjacent to the first overflow port 300, and the fourth pipeline 304 is located at one end away from the first overflow port 300. The second and third pipelines 302, 303 are located between the first and fourth pipelines 301, 304, wherein, these pipelines 301, 302, 303, 304 are respectively provided with a plurality of water release holes (Fig. not shown), so that the electrophoretic solution after the temperature control device 52 can evenly flow into each part of the main tank 30, so that the electrophoretic solution in each part of the main tank 30 can maintain a consistent concentration. Also, please refer to As shown in Figure 6, the first, second and third pipelines 301, 302, 303 are placed at the bottom of the main tank 30, the fourth pipeline 304 is suspended in the main tank 30, and the fourth pipe The water release hole provided by the road 304 is to flow into the electrolytic liquid toward the bottom of the main tank 30, so that the electrophoretic liquid in this part can produce a circulation effect (as shown by the arrow in the figure), so that the fourth tube adjacent to the fourth tube can be avoided. The electrodeposition liquid at the road 304 is too far away from the first overflow port 300, causing the flow rate to be too slow, resulting in the phenomenon of paint deposition, affecting the different concentration of the electrodeposition liquid in each part of the main tank 30, and resulting in uneven color In addition, in other embodiments of the present utility model, the number of these pipelines can be increased or decreased due to the change of the length of the main tank 30 or the change of the flow rate of the electrolytic solution flowing into the main tank 30, However, among the pipelines, at least one pipeline is set at the end far away from the first overflow port 300 and is set in a suspended position, so as to avoid the phenomenon of paint deposition caused by part of the electrolyzed liquid in the main tank 30 .

What needs to be specially mentioned here is that the number of balance pipes in the recovery tank 36 can be increased or decreased according to the needs of the industry, and is not limited to two, and these balance pipes are also provided with a plurality of water release holes. And these discharge holes on the multiple pipelines in the main tank 30 and the multiple balance pipes in the recovery tank 36 can cooperate with the needs of the industry, change its water outlet direction and flow size, so that the main tank 30 and the The concentration of the liquid (electrolyte, solvent) in the recovery tank 36 is more in line with the needs of the industry.

In addition, in another embodiment of the present utility model, referring to FIGS. 3 and 4 again, the recovered electrodeposition liquid flowing into the filter tube 347 can directly flow into the filter before flowing into the temperature control device 52. In the pipe 347 (as shown by the dotted line in the figure), to reduce the workload of the temperature control device 52, again, the electrodeposition liquid that flows into the recovery of the ultrafilter 53 can also flow into the temperature control device 52 first, and then flow into In this ultra-filter 53, to make its decomposition process more smooth, moreover, this sinking pipe 345 also can be changed into the larger pipeline of caliber, and the reclaimed paint that makes this paint recovery pipe 348 flow into, and self-through hole The recovered solvent flowing in 360 is simultaneously injected into the sinking pipe 345 and mixed first, so that the concentration of the electrophoretic solution in the first overflow unit 341 can be more consistent.

The above is only a preferred embodiment of the utility model, and the scope of rights claimed by the utility model is not limited thereto. According to those who are familiar with the art, according to the technical content disclosed in the utility model, they can easily The equivalent changes considered should all belong to the protection category that does not depart from the present utility model.
