Description

Technical Field

[0001] This invention relates to the field of chemical equipment, and in particular to a small-scale color separation and bottling system for high-viscosity coatings. Background Technology

[0002] Currently, high-viscosity coatings are mostly extracted using complex screw pumps or hybrid pumps, which offer higher precision and cost. These pumps are suitable for large-scale paint color separation and filling in factories, as well as high-precision color matching systems, and provide good performance. Generally, a single screw pump or hybrid pump is used in a container holding one type of primary color paint.

[0003] However, for ordinary customers, only a small amount of paint is needed for the exterior spraying and repair of household or small commercial products. The accuracy requirements for color matching are generally not high. If existing equipment is used for preparation, it will result in high equipment costs and will not be widely adopted.

[0004] This system provides a small-scale color separation and bottling system for high-viscosity coatings. It achieves small-scale color separation and bottling of high-viscosity coatings and general color matching at a low cost, and performs closed-loop filtration treatment of cleaning waste liquid, which protects the environment and allows for the reuse of cleaning solvents.

The quantitative filling device utilizes a one-way valve principle and internal pressure variations to control material flow, reducing production costs and simplifying cleaning.

[0023] 4. The filtration device can filter organic cleaning agents used for high-viscosity liquids. With the backwashing function, it can reduce the consumption of organic cleaning agents and the cost of filter replacement.

[0024] 5. Both the quantitative filling device and the extraction and stirring device are equipped with three-way moving mechanisms, which facilitates switching between the quantitative filling device and the extraction and stirring device during the paint extraction process and the cleaning process, reducing labor costs.

[0039] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0040] The present invention will now be described in detail with reference to the accompanying drawings:

[0041] like Figures 1-13 As shown: A small-scale color-separation bottling system for high-viscosity coatings.

[0042] It includes an extraction and stirring device, a quantitative filling device, a washing tank, and a filtration device;

[0043] like Figures 1-5 As shown: The extraction and stirring device includes a carrier 1 and an extraction mechanism 3;

[0044] The extraction mechanism 3 is installed on the carrier 1 and is used for extracting high-viscosity liquids; the extraction mechanism 3 is a screw pump 3 with a built-in single screw.

[0045] like Figures 6-9As shown: The quantitative filling device includes an extraction and volume control component 5 and an infeed / outfeed control component 7;

[0046] The feeding and discharging control component 7 includes a base 71, a feeding channel 72, a feeding one-way ball valve 73, a discharging channel 74, a discharging one-way ball valve 75, and a discharging ball valve return spring 76.

[0047] The feed channel 72 is provided with a base 71, and a lower conical surface 77 is provided on the inner wall of the feed channel 72 to cooperate with the feed one-way ball valve 73, so that when the feed one-way ball valve 73 falls, it cooperates with the lower conical surface 77 to achieve sealing;

[0048] The discharge channel 74 is provided with a base 71. An upper conical surface 78 is provided on the inner wall of the discharge channel 74 to cooperate with the discharge one-way ball valve 75. The discharge ball valve return spring 76 is located below the discharge one-way ball valve 75 and pushes the discharge one-way ball valve 75 upward, so that the discharge one-way ball valve 75 cooperates with the upper conical surface 78 to achieve sealing.

[0049] The extraction mechanism 3 is connected to the feeding channel 72 to send the extracted high-viscosity liquid into the quantitative filling device.

[0050] like Figure 10 , 11 As shown: The filtration device includes a filter tank 41, a filter element 42, a liquid storage tank 43, a liquid inlet pipe 44, a filtrate return pipe 45, a filtrate outlet pipe 46, a cleaning return pipe 47, and a cleaning outlet pipe 48.

[0051] The filter element 42 is fixed inside the filter tank 41, and the inlet pipe 44 is connected to the filter tank 41; one end of the filtrate return pipe 45 is connected to the filter element 42, and the other end of the filtrate return pipe 45 is connected to the storage tank 43; the filtrate outlet pipe 46 is connected to the storage tank 43 for discharging filtrate; one end of the cleaning return pipe 47 is connected to the filtrate outlet pipe 46 to form a branch of the filtrate outlet pipe 46, and the other end of the cleaning return pipe 47 is connected to the filtrate return pipe 45 to form a branch of the filtrate return pipe 45; the cleaning outlet pipe 48 is connected to the inlet pipe 44 to form a branch of the inlet pipe 44.

[0052] The inlet pipe 44 is equipped with an inlet valve 442 and an inlet pump 441; the filtrate return pipe 45 is equipped with a filtrate return valve 451; the filtrate outlet pipe 46 is equipped with a filtrate outlet pump 461; the cleaning return pipe 47 is equipped with a cleaning return valve 471 and a cleaning return pump 472; and the cleaning outlet pipe 48 is equipped with a cleaning outlet pump 481.

[0053] The liquid inlet pipe 44 and the filtrate outlet pipe 46 are connected to the cleaning tank via pipes.

[0054] The extraction mechanism 3 is installed in the raw material tank 9 and is used to extract the paint from the raw material tank.

[0055] The specific usage method of the filter device is as follows:

[0056] Filtration stage: The cleaning outlet pump 481 and the cleaning return valve 471 are closed, while the other valves are open. The solution to be cleaned in the cleaning tank enters the filter tank 41 through the inlet pipe 44, is filtered by the filter element 42, and then flows into the storage tank 43 from the filtrate return pipe 45. Finally, it is discharged back into the cleaning tank from the filtrate outlet pump 461.

[0057] Backwashing stage: Filtrate outlet pump 461, filtrate return valve 451, and inlet valve 442 are closed, while other valves are open. The filtered solution in the storage tank 43 is used for backwashing. The liquid enters the filter element 42 after being pressurized by the cleaning return pipe 47 and the cleaning return pump 472. After rinsing the particles attached to the filter element 42, it flows into the filter tank 41 and is finally discharged from the cleaning outlet pipe 48 to the waste liquid collection tank.

[0058] The filter tank 41 and the liquid storage tank 43 are nested together, with the liquid storage tank 43 located around the filter tank 41. This saves space.

[0059] Furthermore, the screw pump 3 includes a drain pipe 31, a pumping motor 32, a reducer 33, and a screw 34;

[0060] The drainage tube 31 passes through the carrier and is fixedly connected to the carrier 1. The upper side of the drainage tube 31 is provided with a liquid outlet tube 35.

[0061] The extraction motor 32 and the reducer 33 are mounted on the carrier 1. The extraction motor 32 is connected to the screw 34 and drives the screw 34 to rotate.

[0062] The screw 34 passes through the drainage tube 31.

[0063] The liquid outlet pipe 35 here is connected to the feed channel 72.

[0064] The screw 34 has a diameter of 12-38 mm and a thread pitch of 5-30 mm. The inner diameter of the rotating disk 24 is 1-3 mm larger than the diameter of the screw 34, creating a 1-3 mm gap between the screw 34 and the rotating disk 24. This optimization of parameters ensures material extraction when the screw rotates forward and facilitates cleaning when it rotates in reverse.

[0065] The extraction and stirring device also includes a stirring mechanism 2, which includes a stirring motor 21, a stirring drive gear 22, a stirring driven gear 23, a rotating disk 24, and a stirring component 25;

[0066] The rotating disk 24 is mounted on the carrier 1 and can rotate along its axial direction, and the stirring driven gear 23 is coaxially mounted on the upper end of the rotating disk 24;

[0069] The stirring element 25 is mounted on the lower outer surface of the rotating disk 24. Figure 1 As can be seen, the rotating disk 24 is provided with several positioning holes, and the stirring component is installed on the positioning holes.

[0070] The mixing component in this case is a mixing rod with mixing blades. The main purpose of adding a mixing mechanism here is to ensure that the paint has a uniform color and does not settle during the mixing process.

[0071] To optimize the structure, the stirring mechanism 2 and the extraction mechanism 3 are nested together, but they can also be placed side by side in actual use.

[0072] The stirring mechanism here is mainly used to stir the liquid to maintain its fluidity, making it easier for the extraction mechanism to extract it; at the same time, it can also prevent paint splatter from settling and avoid uneven color.

[0073] The feed and discharge control component 7 also includes a discharge nozzle 79, which is connected to the side of the discharge channel 74, so that when the discharge one-way ball valve 75 moves downward, the liquid in the discharge channel 74 is discharged through the discharge nozzle 79.

[0074] The extraction and volume-fixing component 5 includes a fixed bracket 51, a servo motor 52, a reducer 53, a coupling 54, a lead screw 55, a lead screw nut 56, a connecting rod 57, a piston 58, and a cylinder liner 59. The servo motor 52 is connected to and fixed to the fixed bracket 51, and the reducer 53 is connected to the lead screw 55 through the coupling 54. The lead screw nut 56 is fixed to the fixed bracket 51, and the lead screw 55 is threadedly engaged with the lead screw nut 56. The connecting rod 57 is also threadedly engaged with the lead screw 55, so that the connecting rod 57 can move back and forth along its axial direction when the lead screw 55 rotates. The front end of the connecting rod 57 has a piston 58. The cylinder liner 59 is located on the outer periphery of the piston 58 and the connecting rod 57, and one end of the cylinder liner 59 is fixedly connected to the fixed bracket 51. The other end of the cylinder liner 59 is connected to the base 71, and one end of the discharge channel 74 and the feed channel 72 are both connected to the cylinder liner 59.

[0075] Both the extraction and stirring device and the quantitative filling device include three moving mechanisms: a vertical moving mechanism, a left-right moving mechanism, and a front-back moving mechanism.

[0076] The vertical moving mechanism includes a vertical electric push rod 61 and a vertical guide frame 62;

[0077] The left-right moving mechanism includes a left-right electric push rod 63 and a left-right guide frame 64;

[0078] The forward and backward moving mechanism includes a forward and backward electric push rod 65 and a forward and backward guide frame 66;

[0079] The vertical guide frame 62 is provided with a vertical guide groove, and the left and right guide frames 64 are slidably disposed in the vertical guide groove. The vertical electric push rod 61 is connected to the left and right guide frames 64 to control the up and down movement of the left and right guide frames 64.

[0080] The left and right guide frame 64 is provided with left and right guide grooves, and the front and rear guide frame 66 is slidably disposed in the left and right guide grooves.

[0082] The extraction and stirring device is fixed to the front and rear guide groove by the carrier 1; the quantitative filling device is fixed to the front and rear guide groove by the fixed bracket 51.

[0083] The three moving mechanisms drive the extraction and stirring device and the quantitative filling device, allowing the extraction and stirring device to switch between the two processes of extracting liquid and cleaning, and the quantitative filling device to switch between the two processes of filling liquid and cleaning.
