Description

Technical Field

[0001] The invention relates to the technical field of PPS plastic recycling, in particular to waste PPS plastic recycling and processing equipment based on resource recycling. Background Art

[0002] Waste PPS plastic is a difficult-to-degrade polymer material. If it is discarded or landfilled at will, it will occupy a large amount of land resources and may take hundreds of years or even longer to decompose in the natural environment, causing long-term pollution to the soil, water and air. Therefore, effective recycling and treatment of waste PPS plastic is an inevitable requirement to reduce environmental pollution.

[0003] The existing waste PPS plastic recycling and processing equipment cannot ensure uniform feeding of the feeding mechanism, resulting in poor crushing effect and serious equipment wear, and the particle size of the crushed plastic is uneven, which affects the subsequent separation and recycling effect, and reduces the efficiency and product quality of the entire recycling process. The existing waste PPS plastic recycling and processing equipment mostly uses traditional separation methods such as density separation, wind separation, etc., which leads to unsatisfactory separation effect of PPS plastic impurities, affecting the purity of PPS plastic recycling, and the existing waste PPS plastic recycling and processing equipment lacks an effective cleaning liquid recycling system, resulting in a large amount of cleaning liquid waste, increasing production costs, and common recycling and processing equipment often has the problem of incomplete cleaning, and cannot effectively remove stubborn stains and additive residues on the surface of waste plastics, which in turn causes some plastics to be unable to be fully cleaned, affecting the quality and performance of recycled plastics. Summary of the invention

[0005] To achieve the above object, the present invention provides the following technical solutions: The present invention provides a technical solution for waste PPS plastic recycling and processing equipment based on resource reuse. The waste PPS plastic recycling and processing equipment based on resource reuse comprises a feeding mechanism, a No. 1 conveyor belt, a crushing mechanism, a No. 2 conveyor belt, a separation mechanism and a cleaning mechanism. The feeding mechanism is fixedly connected to the No. 1 conveyor belt, the crushing mechanism is fixedly connected to the No. 1 conveyor belt, the crushing mechanism is fixedly connected to the No. 2 conveyor belt, the separation mechanism is fixedly connected to the No. 2 conveyor belt, the cleaning mechanism is fixedly connected to the separation mechanism, and the feeding mechanism, the No. 1 conveyor belt, the crushing mechanism, the No. 2 conveyor belt, the separation mechanism and the cleaning mechanism are arranged in sequence from left to right.

[0006] The feeding mechanism, No. 1 conveyor belt, crushing mechanism, No. 2 conveyor belt, separation mechanism and cleaning mechanism are arranged from left to right in sequence, so that the waste PPS plastic is fed, crushed, separated and cleaned in sequence. When the recycling and processing equipment is working, the operator pours the waste plastic into the feeding mechanism, and the waste PPS plastic is evenly transported to the crushing mechanism through the feeding mechanism via the No. 1 conveyor belt. The waste PPS plastic is broken into small pieces of PPS plastic through the crushing mechanism. The broken small pieces of waste PPS plastic are transported to the separation mechanism through the No. 2 conveyor belt to separate the PPS plastic from plastics of other materials. The separated PPS plastic is cleaned through the cleaning mechanism.

[0007] Furthermore, the feeding mechanism includes a support frame, an electric cylinder, a discharge box, a sealing rod, a baffle and a silo.

[0008] The discharge box is pushed toward the No. 1 conveyor belt through the electric cylinder, so that the sealing rod slides from the opening into the discharge box, and the baffle is moved with the discharge box to block the silo outlet. The electric cylinder contracts to slide the sealing rod from the opening to the opening of the discharge box, thereby pushing a part of the waste PPS plastic in the discharge box out of the discharge box. At the same time, the baffle leaves the silo outlet, so that the waste PPS plastic in the silo is replenished into the discharge box, and the waste PPS plastic pushed out of the discharge box falls onto the support frame, and the electric cylinder pushes the discharge box toward the No. 1 conveyor belt, so that the waste PPS plastic is pushed onto the No. 1 conveyor belt.

[0009] Furthermore, the distal end of the inclined surface is a low end.

[0010] The sealing rod is provided with an inclined surface, and the far end of the inclined surface is the low end, so that the waste PPS plastic at the bottom of the discharge box slides into the discharge box along with the sealing rod, and the waste PPS plastic moves along the inclined surface to the other end of the sealing rod, thereby reducing the resistance to the movement of the sealing rod and avoiding incomplete discharge of the discharge box.

[0011] Furthermore, the crushing mechanism includes a shell, a No. 1 machine base, a No. 1 motor, a transmission shaft, a serrated cutter and a gear.

[0012] Through motor No. 1, the transmission shaft fixedly connected to its output end is driven to rotate, so that the gear connected to the transmission shaft keyway is rotated. Through the two gears, the rotating gear drives another gear to rotate through meshing. The other gear is connected to another transmission shaft through the keyway transmission, so that the other transmission shaft is rotated. Through the rotation of the two transmission shafts, the sawtooth cutter connected to the transmission shaft is driven to rotate, so that the rotating sawtooth cutter shears and squeezes the waste PPS plastic falling into the working chamber. The waste PPS plastic is subjected to forces in different directions from the sawtooth cutter, so that it is broken into small pieces of material.

The separation roller and the mounting frame are fixedly connected. The electrostatic electrode and the mounting frame are fixedly connected. The scraper and the mounting frame are fixedly connected.

[0014] The guide plate is installed on the mounting frame to make the crushed waste PPS plastic fall from the No. 2 conveyor belt onto the guide plate. The electrostatic electrode generates an electrostatic magnetic field to make the PPS plastic carry static electricity. The separation roller carries the same charge as the waste PPS plastic, so that the waste PPS plastic falls into the cleaning mechanism along a parabola. At the same time, impurities with opposite charges to the separation roller are adsorbed on the separation roller. The separation roller rotates to make the scraper scrape off the impurities on the separation roller.

[0015] Furthermore, the cleaning mechanism includes a No. 1 shell, a No. 2 machine base, a No. 2 motor, a rotating shaft, a spiral blade, a No. 1 sleeve, an elastic unit, a circulation unit and a brush.

The No. 1 shell is provided with a feed port located below the separation roller, and the No. 1 shell is provided with a discharge port.

[0016] A feed port located below the separation roller is provided through the No. 1 shell, so that the separated crushed waste PPS plastic falls into the interior of the No. 1 shell, and the No. 2 motor runs smoothly through the No. 2 machine base, and the rotating shaft is driven to rotate by the No. 2 motor, and the rotating shaft is rotatably connected with the No. 1 shell, so that the rotating shaft drives the spiral blade to rotate, so that the spiral blade drives the waste PPS plastic to move toward the discharge port, and at the same time, the spiral blade and the waste PPS plastic roll, so that the waste PPS plastic and the No. 1 sleeve rub against each other for cleaning, and the No. 1 sleeve and the spiral blade are fitted together through the elastic unit, and at the same time, the impact force generated by the friction between the waste PPS plastic and the No. 1 sleeve is reduced, and the vibration of the equipment during operation is reduced, and the cleaning agent for cleaning the waste PPS plastic can be recycled through the circulation unit, and the brush is fixedly connected to the rotating shaft through the provided brush, so that the brush and the rotating shaft rotate synchronously, so that the waste PPS plastic is brushed at the same time.

[0017] Furthermore, the No. 1 sleeve includes a No. 2 outer shell and a horizontal rod, and the horizontal rods are provided in a plurality. The inner wall of the No. 2 outer shell is fixedly connected to the plurality of horizontal rods, and the No. 2 outer shell is provided with a mesh.

[0018] A plurality of horizontal bars are arranged on the inner wall of the No. 2 shell, and the No. 2 shell is provided with mesh holes, which further enhances the scraping of the No. 1 sleeve on the surface of the waste PPS plastic, thereby enhancing the cleaning effect.

[0020] The fixed rod and the No. 1 sleeve are fixedly connected, so that when the spiral blades of the cleaning mechanism and the No. 1 sleeve cooperate to clean the waste PPS plastic, the vibration generated is transmitted to the fixed rod, causing the fixed rod to slide into the No. 2 sleeve, thereby compressing the spring mounted on the fixed rod, and releasing the compressed elastic force through the spring to reset the No. 1 sleeve, so that the No. 1 sleeve and the spiral blades remain in contact, ensuring the cleaning effect.

[0021] Furthermore, the circulation unit includes a mesh plate, a filter, a water pump and a high-pressure nozzle. The No. 1 shell is provided with a water outlet, the mesh plate is placed at the water outlet, the filter is connected to the water outlet pipeline, the filter is connected to the water pump pipeline, and the water pump is connected to the high-pressure nozzle pipeline.

[0022] A mesh plate is placed at the water outlet to prevent waste PPS plastic from falling into the water outlet. The filter is connected to the water outlet pipe to allow the cleaning liquid inside the No. 1 shell to flow into the filter. The filter filters impurities in the cleaning liquid. The water pump is connected to the filter pipe to allow the filtered cleaning liquid to be transported back to the inside of the No. 1 shell through the high-pressure nozzle. The material is flushed through the high-pressure nozzle to achieve the recycling of the cleaning liquid.

[0023] Compared with the prior art, the present invention has the following beneficial effects: 1. The discharge box is pushed toward the No. 1 conveyor belt through the electric cylinder, so that the sealing rod slides from the opening into the discharge box. The electric cylinder contracts, so that the sealing rod slides from the opening to the opening of the discharge box, thereby pushing a part of the waste PPS plastic in the discharge box out of the discharge box. The waste PPS plastic pushed out of the discharge box falls onto the support frame. The electric cylinder pushes the discharge box toward the No. 1 conveyor belt, so that the waste PPS plastic is pushed onto the No. 1 conveyor belt, thereby achieving uniform feeding of waste PPS plastic in batches, making the crushing process stable and efficient, avoiding problems such as equipment idling and overload caused by uneven feeding, extending the service life of the equipment, and improving the crushing quality and efficiency.

[0024] 2. Through the electrostatic characteristics of PPS plastic, the separation mechanism uses electrostatic separation to effectively separate PPS plastic from other impurities, thereby improving the recycling purity of PPS plastic.

[0025] 3. The cleaning mechanism realizes all-round and dead-angle cleaning of waste plastics through the combined design of spiral blades, mesh sleeves and brushes. The brush rotates synchronously with the spiral feed to strongly scrub the waste plastics. By setting a horizontal rod on the mesh sleeve, the friction on the plastic surface is further enhanced, thereby improving the cleaning effect.

[0026] 4. Through the water outlet, the cleaning liquid inside the No. 1 shell flows into the filter. The filter filters the impurities in the cleaning liquid. The water pump is connected to the filter pipeline to make the filtered cleaning liquid re-transported back to the No. 1 shell through the high-pressure nozzle. At the same time, the high-pressure nozzle flushes the material to realize the recycling of the cleaning liquid, saving a lot of cleaning liquid resources, thereby reducing production costs.
