Description

Technical Field

[0001] The utility model relates to the technical field of secondary recycling of waste artificial leather, in particular to color mixing equipment for secondary recycling of waste artificial leather. Background Art

[0002] In the recycling process of waste artificial leather, color matching is a crucial link. Waste artificial leather often contains various pigments, additives and possibly mixed magnetic impurities. The presence of these components not only affects the reuse value of the waste artificial leather, but may also have adverse effects on subsequent processing. Therefore, it is necessary to perform color matching on the waste artificial leather to remove or change its original color and remove impurities as much as possible to meet the requirements of reuse.

[0003] Traditional coloring equipment and methods have some problems when processing waste artificial leather. For example, the colorant in the coloring reaction tank is not mixed evenly with the waste leather pigment, which affects the coloring effect. In addition, the magnetic impurities that may be contained in the waste leather pigment are difficult to effectively remove during the coloring process. The presence of these impurities will further affect the quality of the reuse of waste artificial leather. Therefore, we have made technical improvements to the current coloring equipment to meet the usage needs. Utility Model Content

A magnetic ring is also fixed on the outer peripheral surface of the shaft below each spiral conveying piece to adsorb magnetic impurities mixed in the waste leather pigment. An underflow stirring plate group is also provided on the outer peripheral surface of the shaft below the lowest magnetic ring.

[0008] A waste leather pigment feed port is provided on the top of the tank body, and a plate-frame filter press is provided beside the color mixing reaction tank to pre-filter the waste leather pigment feed port. The discharge port of the plate-frame filter press is connected to the waste leather pigment feed port through a pipeline.

The shaft 6 is vertically arranged, and a spiral conveying piece 7 is fixed on the outer peripheral surface of the middle part of the shaft 6. The spiral conveying piece 7 is formed into an arc-shaped sheet structure;

[0026] Since waste artificial leather is used for a long time, magnetic impurities are easily accumulated on its surface. Therefore, a magnetic ring 8 is fixed on the outer peripheral surface of the shaft 6 below each spiral conveying sheet 7. The magnetic ring 8 is formed into a circular ring structure to adsorb the magnetic impurities mixed in the waste leather pigment.

[0027] In order to improve the solubility of the pigment, an underflow stirring plate group is further provided on the outer peripheral surface of the shaft body 6 below the lowest magnetic ring 8. The underflow stirring plate group includes a long-handled stirring rod 9 and a short-handled stirring rod 10. Both the long-handled stirring rod 9 and the short-handled stirring rod 10 are formed into a roughly round rod-shaped structure.

[0028] The long-handled stirring rod 9 is horizontally fixed on the outer peripheral surface of the shaft body 6, and is fixed on the outer peripheral surface of the shaft body 6 and is located below the lowest magnetic ring 8;

[0029] The short-handled stirring rod 10 is fixed on the outer peripheral surface of the shaft body 6 in an oblique downward direction. It is fixed on the outer peripheral surface of the shaft body 6 and is located below the long-handled stirring rod 9.

[0030] A waste leather pigment feed port 11 is provided on the top of the tank body 1, and a plate-frame filter press 12 for pre-filtering the waste leather pigment feed port 11 is provided next to the coloring reaction tank.

The inlet and outlet of the heat exchange tube 14 extend to the outside of the middle part of the tank body 1.

[0032] The operating principle of the color mixing equipment for secondary recycling of waste artificial leather is:

[0033] (1) Preparation: Ensure that all components are correctly installed and connected, check whether the filter cloth is installed on the plate and frame filter press 12 and is ready for pre-filtration operation, prepare the required toner, and ensure that the toner feed pipe 4 is unobstructed;

[0034] (2) Pre-filtration of waste leather pigments: The collected waste artificial leather pigments are fed into a plate-and-frame filter press 12, which is started to perform a pre-filtration operation to remove large particles of impurities and moisture in the waste leather pigments. The pre-filtered waste leather pigments are automatically fed into the waste leather pigment feed port 11 of the coloring reaction tank through a pipeline;

[0035] (3) Coloring operation: Add the required colorants to the colorant feeding tube 4, start the rotary power mechanism 5, and make the shaft 6 start to rotate, thereby driving the stirring mechanism to stir. The spiral conveying piece 7 and the underflow stirring plate group in the stirring mechanism will work together to fully stir the waste leather pigment and the colorant to promote the uniform distribution of the colorant. At the same time, the magnetic ring 8 will absorb the magnetic impurities that may be contained in the waste leather pigment to ensure the quality of the waste artificial leather after coloring;

[0036] (4) Heating and coloring: During the stirring process, the fluid in the coloring reaction tank is preheated and heated by connecting an external heat source to the inlet and outlet of the heat exchange tube 14. Heating will accelerate the coloring speed of the waste leather pigment and help the toner and the waste leather pigment to fully blend. As needed, the temperature and heating time of the external heat source can be adjusted to achieve the desired coloring effect;

[0037] (5) Discharging and subsequent processing: After the color adjustment is completed, the rotating power mechanism 5 is turned off, the stirring is stopped, and the waste leather pigment discharge port 13 is opened to discharge the color-adjusted waste artificial leather pigment out of the color adjustment reaction tank. The discharged waste artificial leather pigment can be further processed, such as calendering, molding, etc., to make new artificial leather products.
