Description

Technical Field

[0001] The invention relates to the technical field of polyester fiber fabric recycling, in particular to a recycling and processing device for regenerated polyester fiber fabric. Background Art

[0002] As people's living and consumption levels continue to improve, the use cycle of textiles has been greatly shortened, resulting in a large number of waste textiles. Among them, polyester / cotton blended textiles account for a high proportion. However, this blended textile is not easy to recycle and is likely to have adverse effects on the environment after being discarded. From the perspective of environmental protection and resource conservation, recycling and reuse is the most ideal way to deal with waste textiles.

[0003] At present, there are three main methods for recycling and reusing waste textiles, namely physical recycling, energy recycling and chemical recycling. Among them, the physical recycling method is to preliminarily process the waste textiles into a state that can be reused; for example, cut the waste clothes into small pieces and use them as rags, or repair and refurbish the waste carpets that are not seriously damaged. When processing polyester fiber fabrics, after being cut into pieces, they are washed and dried, re-melted for recycling, and then reprocessed. However, the existing drying equipment cannot effectively separate the water vapor between the fragments during drying, because the fragments are stuck together, and the drying effect is poor. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a recycling and processing device for regenerated polyester fiber fabrics, which solves the above-mentioned problems.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: A recycling and processing device for recycled polyester fiber fabrics, comprising a drying box body connected to a discharge port of a cleaning device, wherein the inner cavity of the drying box body is provided with a dispersing mechanism located below the discharge port for dispersing polyester fragments;

[0007] The inner cavity of the drying box body between the air outlet hopper and the recovery hopper is rotatably connected to two toggle wheels arranged in pairs, and the two toggle wheels both rotate toward the direction of the air outlet hopper. When in use, the polyester fragments cleaned by the cleaning equipment are discharged through the discharge port and fall into the dispersion mesh plate wrapped by the elastic connecting cloth. Then, the motor drives the cam to rotate, driving the dispersion mesh plate to vibrate continuously. A large number of mesh holes are provided on the surface of the dispersion mesh plate. At this time, the polyester fragments are broken up into clumps under the shaking of the dispersion mesh plate and fall onto the toggle wheels through the mesh holes. After the polyester fragments are dispersed and fall, the toggle wheels rotate to hit the powder, causing it to move toward the direction of the air outlet hopper, so that it directly contacts the air outlet, and the blowing effect is better, and the water vapor can be effectively separated. The air outlet hopper and There are two recovery hoppers, and they are staggered in groups of two at the top and bottom of the drying box, forming a staggered structure in which air is discharged from the upper right side and recovered on the left side, and air is discharged from the lower left side and recovered on the right side. This structure can effectively separate the water vapor in the polyester fragments. The filter holes of the filter are smaller than the polyester fragments, which can effectively block the polyester fragments, and the water vapor contained in the polyester fragments is blown into the recovery hopper by the hot air blown out from the air outlet hopper by the hot air blower for separation, and the filter is rotated and vibrates continuously under the limit of the elastic sealing belt to prevent the polyester fragments from sticking to the filter and causing blockage. The high-temperature gas carrying water vapor blown out by the water vapor enters the recovery box through the recovery hopper and the recovery pipe, and is recycled by the hot air blower after absorbing water through the built-in water absorption filter, and the hot air can be effectively circulated.

[0008] As a further solution of the present invention: the filter holes of the filter screen are smaller than the polyester fragments, which can effectively block the polyester fragments, and the water vapor contained in the polyester fragments is blown into the recovery bucket by the hot air blown out of the air outlet hopper by the hot air blower for separation.

[0009] As a further solution of the present invention: two air outlet hoppers and two recovery hoppers are provided, and are staggered in groups of two above and below the drying box, forming a staggered structure of air outlet on the right side and recovery on the left side at the top, and air outlet on the left side and recovery on the right side at the bottom, which can effectively separate the water vapor in the polyester fragments.

[0010] As a further solution of the present invention: the dispersion mechanism includes a dispersion mesh plate fixed to the top of the inner cavity of the drying box by an elastic connecting cloth and a cam located in the inner cavity of the drying box driven by a motor, the convex surface of the cam abuts against the bottom of the dispersion mesh plate, and when in use, the polyester fragments cleaned by the cleaning equipment are output through the discharge port and fall into the dispersion mesh plate wrapped by the elastic connecting cloth, and then the motor drives the cam to rotate, driving the dispersion mesh plate to vibrate continuously. A large number of mesh holes are opened on the surface of the dispersion mesh plate. At this time, the polyester fragments are broken up into clumps under the shaking of the dispersion mesh plate and fall through the mesh holes onto the toggle wheel.

[0011] As a further solution of the present invention: a recovery box with a built-in water absorption filter is fixedly connected to the surface of the drying box body, the bottom of the recovery bucket is connected to the recovery box through a recovery pipe, and the exhaust port of the hot air blower is connected to the recovery box through the exhaust pipe. The high-temperature gas carrying water vapor blown out enters the recovery box through the recovery bucket and the recovery pipe, and is recycled by the hot air blower after absorbing water through the built-in water absorption filter, so that the hot air can be effectively circulated.

[0012] As a further solution of the present invention: one side of the exhaust duct is connected to a one-way air intake duct connected to the outside air. When the recovered hot air cannot meet the demand, air is drawn in through the one-way air intake duct for circulation.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In the present invention, the polyester fragments are shaken by the dispersion mesh plate, and the clumps are broken up and fall through the mesh holes onto the toggle wheel. After being dispersed, the polyester fragments fall down, and at this time the toggle wheel rotates to hit the powder, so that it moves toward the direction of the air outlet hopper, so that it directly contacts the air outlet, and the blowing effect is better, and the water vapor can be effectively separated.

This structure can effectively separate the water vapor in the polyester fragments. The filter holes of the filter screen 12 are smaller than the polyester fragments, which can effectively block the polyester fragments, and the water vapor contained in the polyester fragments is blown into the recovery hopper 9 by the hot air blown out from the air outlet hopper 8 by the hot air blower 7 for separation. The filter screen 12 is rotatably set and continuously vibrates under the limit of the elastic sealing belt 13, which can prevent the polyester fragments from adhering to the filter screen 12 and causing blockage.
