Description

TECHNICAL FIELD

[0001] The present disclosure relates to a distillation device and a recycling system comprising the same. BACKGROUND

[0002] In the production of vehicles, it is necessary to spray paint on corresponding parts of the vehicle body in a paint spraying workshop. A paint spraying gun is usually used to spray paint of a specific color onto the vehicle body. When the spraying of the current color is completed and the next color of paint needs to be sprayed, the gun must be cleaned to avoid the paint of the previous color remaining in the gun from contaminating the new paint after replacement, thereby affecting the quality of the spraying work. In addition, in the case where the color of the paint is not changed, since a small amount of paint or impurities in the paint tends to be easily solidified in the gun or around the nozzle of the gun after a long period of use, thereby causing poor spraying or a decrease in the quality of the spraying, the gun also needs to be cleaned in this case.

[0003] Generally, in order to clean the gun, the gun can be inserted into a dedicated cleaning device and the pipeline inside the gun can be flushed with a cleaning solution. After the flushing operation, the cleaning solution can take away the residual paint or impurities in the gun. Finally, the waste liquid formed by the mixing of the cleaning solution with the paint and / or impurities can be transported from the cleaning device and collected into a storage tank for subsequent treatment.

[0004] In the existing production process, vehicle manufacturers often entrust third-party service providers to treat the waste liquid obtained by cleaning the gun. However, since a large amount of waste liquid is generated every day in daily production (up to 4 to 5 tons of waste liquid can be generated per day depending on the production capacity), and the third-party service providers charge a high fee for the treatment of the waste liquid, the treatment of the waste liquid in the existing production process results in a continuous high production cost.

[0005] Therefore, it is desirable to obtain a device and a system capable of recycling a usable solution part contained in the waste liquid. The recycled usable solution part can be used again as a cleaning solution or a partial component of a cleaning solution for the gun.

[0006] In order to extract the usable solution part from the waste liquid, a distillation method can be used to separate the usable solution part from other useless substances (such as waste residues, impurities) in the waste liquid. Bubbles are generated during the distillation process. Since the bubbles can cause a decrease in the distillation efficiency or even hinder the discharge of the distillate, the bubbles must be eliminated during the distillation process, i.e. defoaming. In order to remove the bubbles, a defoaming agent can be added to the solution during the distillation process. However, since the waste liquid contains paint substances, the addition of the defoaming agent can cause the solution part obtained by distillation to still contain a certain amount of paint substances. This can affect the cleaning effect when the recycled solution part is used again to clean the gun or even introduce more contaminants. Utility Model Content

[0031] Figure 1 A distillation apparatus 100 according to the present disclosure is shown. The distillation apparatus 100 is used to perform a distillation operation on a solution to be distilled. In this embodiment, the solution to be distilled is a waste liquid formed from a cleaning solution from a cleaning device used for a paint spray gun, mixed with paint and / or impurities. However, it will be understood that the distillation apparatus according to the present disclosure can also be used to perform distillation operations on other solutions.

[0032] The distillation apparatus 100 includes a housing 10, a stirring assembly 50, and a heating element 90.

[0033] The outer casing 10 defines the distillation chamber 15 of the distillation apparatus 100. The distillation chamber 15 is used to contain the solution to be distilled during the distillation operation. The distillation chamber 15 has a horizontally extending longitudinal axis z.

[0034] The accompanying drawings show a distillation chamber 15 that is generally cylindrical in shape. However, it is understood that the distillation chamber 15 may have other shapes, such as a cuboid shape, etc.

[0035] A stirring assembly 50 is disposed inside the distillation chamber 15. During the distillation operation, the stirring assembly 50 is used to stir the solution to be distilled contained in the distillation chamber 15, thereby making the distillation effect more uniform and promoting the distillation efficiency.

[0036] The stirring assembly 50 includes a shaft 55, at least two stirring plates 60, and at least one defoaming component 70.

[0037] Shaft 55 is a rotatable shaft. Within the distillation chamber 15, shaft 55 extends longitudinally z from one lateral end of the distillation chamber 15 to the opposite lateral end. Shaft 55 is used to drive the stirring plate 60 and the defoaming component 70 to rotate together, thereby achieving a stirring operation.

[0038] One end of shaft 55 may be hermetically connected to a drive unit (not shown), such as a motor, outside housing 10. Alternatively, one end of shaft 55 may be indirectly connected to the drive unit via a transmission device (e.g., belt, chain, etc.).

[0039] At least two stirring plates 60 are fixed to the shaft 55. The stirring plates 60 are the main stirring components during the stirring operation and serve as intermediate parts connecting the defoaming component 70 and the shaft 55.

[0040] The at least two stirring plates 60 may be configured such that the shaft 55 passes through each stirring plate 60. The accompanying drawings show the shaft 55 passing through the center of each stirring plate 60, but without departing from the scope of this disclosure, the shaft 55 may also be configured to pass eccentrically through all or part of the stirring plates 60.

[0041] Each stirring plate 60 has an outer peripheral edge that defines the shape of the stirring plate 60. It should be noted that although the stirring plate 60 is shown in the figures with an outer peripheral edge defining an equilateral triangle, it is understood that the stirring plate 60 may have an outer peripheral edge defining other suitable shapes. Suitable shapes include, for example, squares, pentagons, etc.

[0042] Furthermore, the number of stirring plates 60 is shown as 5 in the attached figure, but it is understood that the number of stirring plates 60 can be set to 2, 3, 4, 6 or more, depending on the amount of solution to be distilled and the requirements for distillation efficiency.

[0043] At least one defoaming component 70 is used to puncture or break bubbles generated in the solution to be distilled during the distillation process as the shaft 55 rotates, thereby achieving the effect of eliminating bubbles.

[0044] Each defoaming component 70 includes a base 72 and multiple defoaming sections 74.

[0045] The base 72 of each defoaming component 72 is attached as a connecting part to the outer peripheral edge of each stirring plate 60. For example... Figure 1As shown, the base 72 of each defoaming component 72 is attached to the same position on the outer peripheral edge of each stirring plate 60, thereby extending approximately in the direction of the longitudinal axis z. However, it is understood that the base 72 may be attached to different positions on the outer peripheral edge of each stirring plate 60, for example, the base 72 may be configured to extend in a spiral form.

[0046] Multiple defoaming portions 74 of each defoaming component 70 extend from the corresponding base 72 in a direction away from the axis 55. The multiple defoaming portions 74 are arranged on the corresponding base 72 in a spaced-apart manner. The defoaming portions 74 are used to contact and puncture or break bubbles when the stirring assembly 50 rotates.

[0047] The accompanying drawings show that the defoaming section 74 is in the form of fins, but the defoaming section 74 can also take other forms. For example, the defoaming section 74 can be needle-shaped, elongated cylinders, etc. The accompanying drawings also show that the plurality of defoaming sections 74 of each defoaming member 70 are spaced apart from each other at equal intervals, but it is understood that the plurality of defoaming sections 74 can have different spacings from each other.

[0048] Furthermore, in the accompanying drawings, the two defoaming members 70 are shown attached to two vertices of the triangular outer periphery of each stirring plate 60, respectively. However, those skilled in the art will understand that different numbers of defoaming members 70 can be provided without departing from the scope of this disclosure, for example, only one defoaming member 70 or three or more defoaming members 70. Additionally, the defoaming members 70 can also be attached to locations other than the vertices of the triangular outer periphery of the stirring plate 60. Furthermore, for stirring plates 60 with other shaped outer periphery edges, the defoaming members 70 can similarly be provided at the corresponding vertices or other locations.

[0049] The heating unit 90 serves as the heat source for the distillation apparatus, providing the necessary heat for distillation to the distillation chamber 15. The heating unit 90 is located adjacent to the bottom of the distillation chamber 15. The heating unit 90 has a heating chamber 95. The heating chamber 95 can contain a heating gas. This heating gas is used to heat the solution to be distilled in the distillation chamber 15. The heating chamber 95 is isolated from the distillation chamber 15. That is, the heating gas in the heating chamber 95 is isolated from the solution to be distilled or the gaseous distillate in the distillation chamber 15.

[0050] In this embodiment, as Figure 2 As shown in the schematic side cross-sectional view, the heating element 90 is formed with a crescent-shaped cross-section adjacent to the bottom of the distillation chamber 15, wherein the heating chamber 95 is shown in shaded areas. However, it is understood that the heating element 90 may be formed with other cross-sectional shapes without departing from the scope of this disclosure. For example, the bottom arc of the crescent-shaped cross-section may be transformed into a combination of straight segments, such as the three sides of a rectangle, thereby forming a cross-section with corners at the bottom.

[0051] The distillation apparatus 100 may also include a vacuum pump. The vacuum pump is in communication with the distillation chamber 15 via a port on the housing 10. The vacuum pump is configured to provide a negative pressure within the distillation chamber 15. Preferably, the vacuum pump provides a negative pressure of -80 kPa to -90 kPa within the distillation chamber 15.

[0052] The vacuum pump provides negative pressure in the distillation chamber 15, which lowers the boiling point in the chamber, allowing the gaseous distillate to be obtained at a lower temperature, thus performing the distillation operation in a more economical way.

[0053] The distillation apparatus 100 may further include a solution inlet and a gas outlet. The solution inlet is used to supply the solution to be distilled into the distillation chamber 15. The gas outlet is used to discharge the gaseous distillate from the distillation chamber 15 during the distillation process. The gas outlet is located on the top of the housing 10, thereby utilizing the buoyancy of the gaseous distillate to draw the distillate out of the distillation chamber 15 of the distillation apparatus 100.

[0054] The distillation apparatus 100 may further include a heating gas inlet. The heating gas inlet is disposed on the heating section 90 for supplying the heating gas to the heating chamber 95. Furthermore, the distillation apparatus 100 may also include a condensate outlet. The condensate outlet is disposed on the heating section 90 to allow the heating gas, which condenses into liquid during heating, to leave the heating section, thereby preventing condensate from accumulating in the heating chamber 95 and affecting the heating effect.

[0055] The distillation apparatus 100 may also include a residue outlet. The residue outlet is located near the bottom of the distillation chamber 15 on one of the lateral ends of the distillation chamber 15 to facilitate the discharge of residue from the distillation chamber 15 after distillation operations.

[0056] By using the distillation apparatus 100 according to this disclosure, when distilling the solution to be distilled in the distillation chamber 15, the solution to be distilled can be stirred by the stirring plate 60 in the stirring assembly 50. At the same time, the defoaming component 70 in the stirring assembly 50 can eliminate bubbles generated in the solution to be distilled. Thus, bubble elimination can be achieved without adding any defoamer to the distillation apparatus 100, thereby improving the efficiency and quality of the distillation operation of waste liquid from paint spray guns.

[0057] Figure 3 A schematic block diagram of a recycling system 1000 according to the present disclosure is shown. The recycling system 1000 is used to recover reusable liquid from waste liquid obtained after cleaning a paint spray gun at a paint spray gun cleaning device 2000. The recycling system 1000 includes the aforementioned distillation device 100, raw water storage tank 200, condenser 300, first transfer pump 400, and second transfer pump 500 according to the present disclosure.

[0058] The raw water storage tank 200 is used to receive waste liquid, i.e., the solution to be distilled. In this embodiment, the raw water storage tank 200 is connected to the cleaning device 2000 to receive and collect waste liquid formed by the mixing of cleaning solution with paint and / or impurities from the cleaning device 2000 for the paint spray gun.

[0059] A first delivery pump 400 is connected to the distillation apparatus 100 and the raw water storage tank 200. The first delivery pump is configured to pump the solution to be distilled from the raw water storage tank 200 into the distillation chamber 15 of the distillation apparatus 100.

[0060] The first delivery pump 400 can be connected to the solution inlet of the distillation apparatus 100.

[0061] As described above, the distillation apparatus 100 uses heating gas in the heating chamber 95 of the heating unit 90 to heat the solution to be distilled in the distillation chamber 15, thereby achieving the distillation operation. During the distillation operation, the stirring assembly 50 of the distillation apparatus 100 rotates, so that the stirring plate 60 of the stirring assembly 50 stirs the solution to be distilled, and the defoaming member 70 of the stirring assembly 50 eliminates the bubbles generated in the solution to be distilled.

[0062] The condenser 300 is connected to the distillation chamber 15 of the distillation apparatus 100. The condenser 300 receives the gaseous distillate obtained from the distillation operation from the distillation apparatus 100 and is configured to cool the gaseous distillate into a liquid reusable liquid.

[0063] The condenser 300 can be connected to the gas outlet of the distillation apparatus 100.

[0064] The condenser 300 can be attached to the distillation apparatus 100, or it can be arranged as a separate component away from the distillation apparatus 100.

[0065] The second transfer pump 500 is connected to the condenser 300 and the cleaning device 2000. The second transfer pump 500 is configured to pump the liquid reusable liquid in the condenser 300 back to the cleaning device 2000.

[0066] The recovery system 1000 may also include a heating gas supply device 600. The heating gas supply device 600 is connected to the heating chamber 95 of the heating section 90 of the distillation apparatus 100 for supplying heating gas to the heating chamber.

[0067] The heating gas supply device 600 can be connected to the heating gas inlet of the heating unit 90.

[0068] The heating gas supply device 600 can be an evaporator, boiler, or any device capable of converting liquid into hot steam. The heating gas supply device 600 can be connected to the condensate outlet of the heating section 90 of the distillation apparatus 100 for returning condensate from the heating section 90 to the heating gas supply device 600.

[0069] The recovery system 1000 may also include a return water storage tank 700 for receiving and collecting reusable liquid from the condenser 300. The return water storage tank 700 may be connected to a second transfer pump 500 and the condenser 300.

[0070] The recovery system 1000 may also include a residue storage tank 800 connected to the distillation chamber 15 of the distillation apparatus 100. The residue storage tank 800 is used to receive and collect residues from the distillation chamber 15 during the distillation operation, thereby preventing residues from accumulating inside the distillation chamber 15. The residue storage tank 800 may be connected to the residue outlet of the distillation apparatus 100.

[0071] The raw water storage tank 200, the return water storage tank 700, and the residue storage tank 800 may all be containers such as boxes, tanks, or other forms of containers without departing from the scope of this disclosure.

[0072] A pressure transmitter may be installed in one or both of the raw water storage tank 200 and the return water storage tank 700 to monitor the pressure of the liquid inside the containers. Alternatively or additionally, a level sensor may be installed in one or both of the raw water storage tank 200 and the return water storage tank 700 to monitor the liquid level inside the containers.

[0073] The recovery system 1000 may also include a reverse osmosis filter for filtering the reusable liquid from the condenser 300, thereby improving the quality of the liquid recovered to the cleaning unit 2000. The reverse osmosis filter may be located downstream of the condenser 300 and upstream of the cleaning unit 2000.

[0074] Thus, by means of the above-mentioned recycling system 1000, a portion of the reusable liquid can be recovered from the waste liquid in the cleaning device 2000 for paint spray guns, and the reusable liquid can be recycled back to the cleaning device 2000 to be used as a cleaning solution or a component of the cleaning solution used by the cleaning device 2000.

[0075] While exemplary embodiments of this disclosure have been described, those skilled in the art will understand that various changes and modifications can be made to the exemplary embodiments of this disclosure without departing from the spirit and scope thereof.
