Technical Field

[0001] This utility model relates to the field of paint recycling technology, and in particular to a paint color separation and recycling device. Background Technology

[0002] Paint is a chemical mixture that can firmly cover the surface of an object, serving as a protective, decorative, marking, and other special-purpose coating. It is named after the fact that people originally used vegetable oil as the main raw material to produce paint.

[0003] Paint is used everywhere in modern production and daily life. In industrial production, paint needs to be atomized and sprayed onto workpieces in paint booths, resulting in paint dispersing into the air. During air purification, capturing and recycling this paint mist helps reduce costs and increase efficiency. Furthermore, the variety of paint types and color codes significantly increases the recycling value of paints with the same designation and color. Utility Model Content

[0004] To address the aforementioned problems, this utility model discloses a paint color separation and recycling device, comprising several stacked diversion units. Each diversion unit includes a main body, inside which are arranged a conveying channel and a return channel. A connection port is provided on the upper surface of the main body, and the connection port communicates with the conveying channel. The arrangement of the conveying channel and the return channel meets the requirements for paint recycling. Furthermore, the diversion units are designed as separate units, allowing for adjustments based on the number of subsequent recycling tanks.

[0005] An opening is provided at the bottom of the main body, and the opening communicates with the return channel. A connecting pipe is threaded to the opening. A valve plate is provided above the connecting pipe, and the valve plate blocks the opening and the return channel. A guide post is fixedly connected below the valve plate. A support rod is provided inside the connecting pipe, and the guide post passes through the support rod. A spring is sleeved on the guide post, and the two ends of the spring abut against the upper end of the support rod and the bottom of the valve plate, respectively. A linear transmission component is fixedly connected to the upper end of the main body. A push rod is fixedly connected to the output end of the linear transmission component, and the push rod extends directly above the valve plate. That is, when the linear transmission component is activated, specifically when the push rod extends and pushes the valve plate downward, the opening and the return channel open, and the returning liquid enters the connecting pipe from the return channel. The connecting pipe is connected to the recovery tank through a pipeline.

[0006] Preferably, a bend is fixedly connected above the connection port, and an electrically controlled water valve is fixedly connected to the other end of the bend. A water pump is installed in the recovery tank to extract the temporarily stored liquid and pump it into the delivery channel via a pipe connected to the electrically controlled water valve.

[0007] Preferably, a connecting plate is provided on one side of each of the stacked diversion units. The connecting plate is provided with a delivery port and a return port, and the delivery port is connected to the delivery channel, while the return port is connected to the return channel. Additionally, a paint mist purification device is provided, with a nozzle at the top and a manifold at the bottom. The delivery port is connected to the spray nozzle via a pipe, and the manifold is connected to the return port via a pipe.

[0008] Preferably, the edges of the stacked diversion units and connecting plates are interspersed with screws and nuts. These screws and nuts connect them into a single unit.

[0009] Preferably, the outermost of the stacked diversion units has its conveying and return channels blocked on one side, and a sealing plate is fixedly connected to its upper end. This diversion unit is used to connect to a cleaning pipe for supplying clean water.

[0010] Preferably, the connecting pipe has an internal threaded connection to a connecting ring, and the end of the support rod is fixedly connected to the inner wall of the connecting ring. By setting the position of the connecting ring inside the connecting pipe, the magnitude of the spring force can be controlled after the connecting pipe is installed.

[0011] Preferably, the linear transmission component is an electric cylinder or a power-off holding electromagnet.

[0012] Preferably, the stacked diversion units and connecting plates are integrated into one unit. This alternative arrangement eliminates the need for screws and nuts, reducing structural complexity and improving the stability of the device.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. It is equipped with multiple diversion units, which can send the returned paint back to the corresponding recycling tank, thereby increasing the value of recycling.

[0015] 2. The system is equipped with a structure that allows connection to the cleaning pipe, ensuring that residual paint in the pipes does not cause contamination when switching recycling tanks.

[0016] 3. There are two types of structures. One is a split structure, which has multiple diversion units and connecting plates. The corresponding diversion units can be added according to the number of return tanks and changed as needed. The other is an integrated structure, which eliminates concerns about the sealing between the diversion units and connecting plates and is better as a whole, thus eliminating the need for related structures.

[0027] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention. It should be noted that the terms "front", "rear", "left", "right", "up" and "down" used in the following description refer to the directions in the accompanying drawings, and the terms "inner" and "outer" refer to the directions toward or away from the geometric center of a specific component, respectively. Example 1

[0028] like Figures 1 to 6As shown, a paint color separation and recycling device includes several stacked diversion units 4. The appropriate number of diversion units 4 can be arranged according to the number of recycling tanks. Each diversion unit 4 includes a main body 41. The side profile of the main body 41 is a large rectangle and a small rectangle is provided in the middle of one side of the large rectangle. The main body 41 is provided with a conveying channel 42 and a return channel 43. The conveying channel 42 is located inside the small rectangle, while the return channel 43 is located inside the large rectangle. The upper end face of the main body 41 is provided with a connection port 414, specifically on the upper end face of the small rectangle. The connection port 414 is connected to the conveying channel 42, so that liquid can be pumped into the conveying channel 42 through the connection port 414.

[0029] An opening is provided at the bottom of the main body 41, and the opening is connected to the return channel 43, meaning that the return liquid can flow downward from the opening. A connecting pipe 44 is threadedly connected to the opening, and a valve plate 49 is provided above the connecting pipe 44. The valve plate 49 blocks the opening and the return channel 43. The edge of the valve plate 49 is stepped and matches the inside of the opening. A sealing ring is further provided on the edge of the valve plate 49, and the sealing ring contacts the upper inner wall of the opening. In addition, the inner wall of the opening is recessed, meaning that when the valve plate 49 moves downward, the opening and the return channel 43 are linked. A guide post 412 is fixedly connected below the valve plate 49, and the connecting pipe 41... The body 4 has a support rod 413 inside, and a guide post 412 passes through the support rod 413. A spring 410 is sleeved on the guide post 412, and the two ends of the spring 410 abut against the upper end of the support rod 413 and the bottom of the valve plate 49, respectively. Under the pressure of the spring 410, the valve plate 49 is kept closed. A linear transmission component 45 is fixedly connected to the upper end face of the body 41. A push rod 46 is fixedly connected to the output end of the linear transmission component 45, and the push rod 46 extends to the top of the valve plate 49. The working push rod 46 of the linear transmission component 45 extends out and pushes the valve plate 49 downward, thereby realizing the connection between the opening and the return channel 43.

[0030] A bend 47 is fixedly connected above the connector 414, and an electrically controlled water valve 48 is fixedly connected to the other end of the bend 47. The other end of the electrically controlled water valve 48 is connected to the pipe for conveying liquid, and the electrically controlled water valve 48 is opened to allow the liquid to enter the conveying channel 42.

[0031] A connecting plate 3 is provided on one side of several stacked diversion units 4. The connecting plate 3 is provided with a conveying pipe 1 and a return pipe 2. The conveying pipe 1 is connected to the conveying channel 42, and the return pipe 2 is connected to the return channel 43.

[0032] Several stacked diversion units 4 and connecting plates 3 are interspersed with screws and nuts 6. The screws and nuts 6 are used to achieve integrated installation.

[0033] The outermost of several stacked diversion units 4 has its conveying channel 42 and return channel 43 blocked on one side, and a sealing plate 5 is fixedly connected to its upper end. This diversion unit 4 is used for cleaning, that is, one end of its electrically controlled water valve 48 is connected to a cleaning pipe for pumping in clean water.

[0034] The connecting pipe 44 has an internal threaded connection to a connecting ring 411. The connecting ring 411 and the connecting pipe 4 are fitted together by the threaded connection, which also makes it easy to change the position of the connecting ring 411, thereby improving the preload of the spring 410 after installation. The end of the support rod 413 is fixedly connected to the inner wall of the connecting ring 411, so as to connect the support rod 413.

[0035] The linear transmission component 45 is either an electric cylinder or a power-off holding electromagnet. The appropriate choice can be made based on performance requirements and production costs.

[0036] like Figure 7 As shown in the figure, the color separation and recycling device is constructed as shown in the figure. It mainly includes a paint mist purification device and multiple recycling tanks. Different recycling tanks collect the same type of paint, and the color separation and recycling device recycles the paint into the corresponding recycling tank, as detailed below.

[0037] Firstly, the paint mist purification equipment has a nozzle at the top and a manifold at the bottom. The nozzle is connected to the delivery pipe 1, and the manifold is connected to the return pipe 2. Next, for ease of installation, one return pipe corresponds to one diversion unit 4. The return pipe has an outward pumping pipe connected to the electrically controlled water valve 48, and is also connected to the return pipe and connecting pipe 44. Finally, for ease of explanation of the working principle, the electrically controlled water valve 48 is referred to as valve one, the linear transmission component 45, valve plate 49, etc., are referred to as valve two, and the electrically controlled water valve 48 connecting to the cleaning pipe is referred to as valve three. The return pipe can be divided into tank one, tank two, etc., and the following two working modes are described:

[0038] Reflux mode: Valve 1 in tank 1 is opened, and the liquid in tank 1 is sent to the paint mist purification equipment through the conveying channel 42. The refluxed liquid enters the reflux channel 43. Valve 2 in tank 1 is opened and enters tank 1. When the paint concentration in tank 1 increases, the liquid in tank 1 can be temporarily stored.

[0039] Cleaning mode: When switching from tank one to tank two, the cleaning operation is performed first. Valve one in tank one is closed and valve three is opened to pump in clean water to clean the paint in the entire pipeline. The cleaning liquid is then returned to tank one. After the cleaning is completed, valve three is closed and valve two in tank one is closed. At this time, valves one and two in tank two can be opened. Example 2

[0040] The difference from Embodiment 1 is that the several stacked diversion units 4 and the connecting plate 3 are integrated into one unit, which makes the overall integrity of the color separation and recycling device better. The sealing between the diversion units 4 does not need to be considered, and the screw and nut 6 are omitted, simplifying the structure.

[0041] The technical means disclosed in this utility model are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features.
