AI Technical Summary
In existing technologies, polymer membrane materials tend to adhere to the walls due to electrostatic effects after being broken, making them difficult to collect, resulting in resource waste and environmental pollution.
The process employs a combination of a primary crusher and a secondary crusher with an electrostatic eliminator to gradually break down the polymer waste film into powder. The electrostatic eliminator then eliminates static electricity, allowing the crushed waste film to fall into the feeding mechanism under gravity.
It achieves effective crushing and quantitative feeding of polymer waste membranes, solves the problem of electrostatic adhesion, improves resource utilization, and reduces environmental pollution.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of polymer membrane recycling and regeneration technology, and in particular to a polymer membrane material recycling and feeding device. Background Technology
[0002] Membrane separation technology is widely used in industries such as textiles and biomedicine due to its advantages such as high separation efficiency and small footprint. However, during the membrane manufacturing process, some substandard membranes are produced due to operational errors. In addition, some scraps are generated during packaging and cutting. These two types of membranes are not put into use and can be directly recycled without cleaning. However, they are usually treated as general solid waste and directly disposed of. Conventional treatment methods such as incineration and landfill will cause resource waste and are detrimental to the environment.
[0003] Existing membrane recycling equipment, such as CN211518241U and CN221834770U, simply crushes the waste membrane with a crushing roller and collects it for later use. However, many membrane materials are charged, such as polyvinylidene fluoride. Waste membranes that are only crushed into sheets are easily stuck to the wall due to electrostatic repulsion and are difficult to collect. Utility Model Content

[0006] It also includes a feeding mechanism, into which the waste film after being crushed by the primary crusher and the secondary crusher falls and is fed quantitatively by the feeding mechanism;
[0007] The primary crusher and the secondary crusher are each equipped with multiple sets of static electricity elimination mechanisms. These mechanisms eliminate static electricity in the primary and secondary crushers, allowing the crushed waste film to fall into the feeding mechanism under gravity.
[0008] Preferably, the primary crusher and the secondary crusher are arranged vertically in a single sequence, and their crushing chambers are interconnected. The waste film is crushed into powder by the primary crusher and the secondary crusher in sequence.
[0009] Preferably, the primary crusher is equipped with two coarse crushing rollers, which crush the waste film into flakes or strips under the action of the two coarse crushing rollers.
[0010] Preferably, the coarse crushing roller uses trapezoidal blades for crushing.
[0011] Preferably, the coarse crushing roller is equipped with a primary crushing motor, which drives the two coarse crushing rollers to rotate under the transmission of the sprocket.
[0012] Preferably, the secondary crusher is equipped with two fine crushing rollers, which crush the waste film into powder under the action of the two fine crushing rollers.
[0013] Preferably, the fine crushing roller is equipped with a two-stage crushing motor, which drives the two fine crushing rollers to rotate under the transmission of the sprocket.
[0014] Preferably, the fine crushing roller uses triangular blades for crushing.
[0015] Preferably, the feeding mechanism includes a feeding hopper and a screw conveyor. The feeding hopper is connected to the bottom of the secondary crusher and is used to collect waste film powder. The screw conveyor is connected to the bottom of the feeding hopper and conveys the waste film powder in a quantitative manner.
[0016] Preferably, the static electricity elimination mechanism is provided in multiple sets, which are staggered on the box walls of the primary crusher and the secondary crusher;
[0017] The static electricity elimination mechanism includes a fixed base, an ion generator, and an ion gas pipe. The static electricity elimination mechanism is fixedly installed on the box wall of the crushing mechanism via the fixed base, and one end of the ion gas pipe extends to the crushing chamber, while the other end is connected to the ion generator. The charged ions generated by the ion generator are blown into the crushing chambers of the primary crusher and the secondary crusher through the ion gas pipe.
[0018] Compared with the prior art, the beneficial effects of this utility model are:
[0019] 1. The polymer membrane material recycling and feeding device of this utility model uses a primary crusher and a secondary crusher to crush the polymer waste membrane, which can gradually crush the polymer waste membrane into powder for quantitative feeding by the subsequent feeding mechanism;
