Description

Technical Field

[0001] This invention belongs to the field of plastic recycling technology, specifically an environmentally friendly polyethylene waterproof membrane processing device. Background Technology

[0002] Polyethylene waterproof membrane is one of the most widely used polymer waterproof materials in the field of building waterproofing. Its core base material is polyethylene resin, which is a thermoplastic plastic with inherent properties of being meltable and reshapeable. This is the core basis for its ability to be recycled. Polyethylene resin can be readjusted and processed in a high-temperature molten state, and its chemical properties are stable. Even after long-term use and aging, the base material can still maintain good plasticity. After recycling and proper processing, it can be remade into various low-grade plastic products or medium and low-grade waterproof membranes.

[0003] The recycling of waste polyethylene waterproof membrane has now formed a relatively mature basic process, which generally follows the core steps of "pre-treatment - crushing - cleaning - drying - granulation". Among them, pre-cleaning is the first step in the recycling process. It mainly involves manually or mechanically sorting the recycled waste membrane to remove large pieces of construction waste mixed in, and at the same time peeling off large pieces of obvious adhering substances on the surface of the membrane. After pre-cleaning, the screened membrane is sent to a special crushing equipment, where it is sheared and crushed into small fragments or particles. The crushed membrane fragments then enter the cleaning stage, which usually uses high-pressure water washing, mechanical kneading and chemical cleaning to remove soluble and insoluble impurities such as dust, dirt and oil adhering to the surface of the fragments. After cleaning, it needs to be dried. The dried and clean membrane fragments are finally sent to the granulation equipment, where they are processed into recycled polyethylene granules through a series of processes such as high-temperature melting, plasticizing, extrusion and pelletizing.

[0004] However, in actual recycling, a large number of polyethylene waterproof membranes on the market are adhesive-type, with a special adhesive layer on their surface for bonding and fixing during construction. Even after the membrane is recycled, some debris, mainly cement slurry, concrete debris, and sand particles, remains on the membrane, forming a complex layer of impurities that is difficult to peel off. During crushing, the hard debris adhering to the membrane will cause severe friction with the blades and barrel of the crushing equipment, accelerating equipment wear and increasing maintenance costs. Furthermore, the membrane fragments after crushing tend to stick together due to residual adhesiveness, trapping debris inside. Conventional cleaning methods cannot completely remove this trapped debris, resulting in incomplete cleaning and a large amount of impurities remaining in the membrane fragments. When these incompletely cleaned membrane fragments enter the granulation stage, they will adversely affect the granulation process and the quality of the recycled granules, severely limiting the effectiveness and value of recycling. Summary of the Invention

[0018] The inclined plate is attached to the push plate on the side closest to the push plate, and the bottom plane of the inclined plate is flush with the bottom of the push plate.

[0019] In a preferred embodiment of the present invention, a circular groove is provided in the inclined plate; a rotating rod is provided in the circular groove, and the rotating rod rotates on the second baffle.

[0020] One of the rotating rods extends into the inner ring of the second conveyor belt and fits against the inner ring of the second conveyor belt; a gear is fixed to one side of the rotating rod extending into the inner ring of the second conveyor belt, and the inner ring of the second conveyor belt has a toothed groove that meshes with the gear;

[0025] In a preferred embodiment of the present invention, guide plates are fixed on both sides of the skateboard, and the guide plates are inclined to both sides respectively.

[0026] In a preferred embodiment of the present invention, the inner rings of the drive belt, the first conveyor belt, and the second conveyor belt are all provided with filler plates;

[0033] The servo motor is equipped with a lead screw, which passes through the top support plate and is driven by the support plate in a helical motion.

[0034] The beneficial effects of this invention are as follows:

[0035] 1. The environmentally friendly polyethylene waterproof membrane processing equipment of this invention utilizes a double-layer clamping conveyor structure formed by two sets of staggered intersecting second conveyor belts and a first conveyor belt. Combined with drive belts on both sides of the two sets of second conveyor belts and scrapers, it enables a two-stage progressive scraping of the membrane surface. The first scraping removes the adhesive layer, cement slurry, concrete debris, sand particles, and other hard debris from the main body of the membrane. The second scraping targets areas of the membrane that were obscured by the second conveyor belts during the first scraping, thus removing the adhesive layer and debris from the membrane surface and preventing severe friction between hard debris and the cutting rollers and blades in the processing chamber during the crushing process. This process fundamentally reduces wear and tear on the cutter blades, chipping, and wear on the cutter rollers, extending the service life of the core crushing components. It also prevents roll material fragments from sticking together due to residual adhesiveness, thus avoiding the trapping of impurities inside the sticky fragments. As a result, the crushed roll material fragments are dispersed, allowing impurities to be fully exposed on the surface. Subsequent conventional cleaning methods can then thoroughly remove these impurities, solving the problems of incomplete cleaning and high impurity residue rates in traditional processes. This significantly improves the cleanliness of the roll material fragments, preventing impurities from affecting the physical properties and appearance of the recycled granules, and ultimately increasing the recycling rate of polyethylene resources.

[0036] 2. The environmentally friendly polyethylene waterproof membrane processing equipment described in this invention utilizes a driven belt fixedly connected to the drive belt to achieve synchronous linkage, driving the rubber push plate to rotate in a cycle. The push plate and the inclined plate are closely fitted to form a connection. When the membrane passes under the driven belt, the push plates on both sides move synchronously along the surface of the membrane towards both sides of the first conveyor belt, realizing bidirectional flattening of the membrane and eliminating residual surface wrinkles after the membrane is unfolded. This ensures that every area of ​​the membrane surface can contact the subsequent scraper, avoiding dead corners caused by unevenness of the membrane, and guaranteeing the efficiency and thoroughness of scraping off the adhesive layer and hard impurities.

[0037] 3. The environmentally friendly polyethylene waterproof membrane processing equipment described in this invention uses an auxiliary frame driven by a drive belt to move the pressure roller synchronously with the scraper. The pressure roller performs localized fine secondary flattening on the pre-leveled membrane, eliminating localized protrusions and curling edges generated during membrane conveying, ensuring the membrane is completely adhered to the first conveyor belt, guaranteeing full contact between the scraper and the membrane surface, and improving scraping accuracy. At the same time, the filler plate inside the drive belt can withstand the reaction force of the scraper during scraping, preventing the drive belt from being concave inward due to resistance, ensuring the scraper maintains a constant scraping force and adheres tightly to the membrane surface, eliminating problems such as incomplete scraping by the scraper and residue of adhesive layer and debris due to belt concavity.

[0050] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0051] like Figures 1 to 10 As shown, the environmentally friendly polyethylene waterproof membrane processing equipment of the present invention, as an embodiment of the present invention, includes a processing chamber 1; two blade rollers rotate inside the processing chamber 1, and the blade rollers are driven by a first motor; each blade roller is fixed with a cutter 11.

[0052] A processing mechanism is provided above the processing chamber 1; the processing mechanism includes a first conveyor belt 2, and the end of the first conveyor belt 2 extends above the two cutters 11;

[0053] The first conveyor belt 2 is provided with first baffles 21 on both sides, and the first conveyor belt 2 rotates between the two first baffles 21 by a rotating roller and is driven by a second motor; the bottom of the first baffle 21 is equipped with support legs;

[0054] Two second conveyor belts 3 are provided above the first conveyor belt 2, and the two second conveyor belts 3 are staggered and partially intersect each other; one of the second conveyor belts 3 extends to the end of the first conveyor belt 2, and the other second conveyor belt 3 extends to the beginning of the first conveyor belt 2, and there is a gap between the two second conveyor belts 3.

[0055] The second conveyor belt 3 is provided with second baffles 31 on both sides, and the second conveyor belt 3 rotates between the two second baffles 31 by a rotating roller and is driven by a third motor;

[0056] Both sides of the two second conveyor belts 3 are provided with drive belts 4, and the drive belts 4 are arranged perpendicular to the second conveyor belts 3; the drive belts 4 on both sides of the second conveyor belts 3 near the beginning of the first conveyor belt 2 extend to the middle of the second conveyor belt 3;

[0057] The drive belt 4 extends from the side away from the second conveyor belt 3 toward both sides of the first conveyor belt 2, and partially extends out of the first conveyor belt 2;

[0058] Each of the multiple drive belts 4 is provided with a third baffle 41 on both sides, and the third baffle 41 is fixed on the second baffle 31 and is arranged perpendicular to the second baffle 31.

[0059] Multiple drive belts 4 are rotated on two third baffles 41 by rotating rollers and driven by a fourth motor; the outer ring of each drive belt 4 is fixed with uniformly arranged scrapers 42.

[0060] In practice, when recycling the rolled material, the recycled waste rolled material is first sorted manually or mechanically to remove large pieces of construction waste mixed in, and large pieces of obvious adhering material on the surface of the rolled material are peeled off. The recycled rolled material is then unfolded into a flat state, and then the rolled material can be crushed. During the crushing process, the first motor drives the cutter roller and the cutter 11 to rotate, while the second motor and the third motor drive the first conveyor belt 2 and the second conveyor belt 3 to rotate slowly. The first conveyor belt 2 and the second conveyor belt 3 have the same speed and opposite rotation direction, both rotating towards the processing chamber 1. At the same time, the fourth motor drives multiple drive belts 4 to rotate, and the drive belts 4 located on both sides of the second conveyor belt 3 rotate in opposite directions and towards both sides of the first conveyor belt 2. Then the rolled material can be processed.

[0061] Specifically, the unfolded roll of material is first placed at the beginning of the first conveyor belt 2 with the adhesive side facing upwards. Then, the roll is placed between the first conveyor belt 2 and the second conveyor belt 3 near the beginning. The roll is held between the first conveyor belt 2 and the second conveyor belt 3, causing the unfolded roll to move towards the processing chamber 1. During this movement, the roll is gradually drawn under the drive belts 4 on both sides of the second conveyor belt 3, away from the processing chamber 1. The rotating drive belts 4 drive the scraper 42 to rotate, and the scraper 42 rotates along a path that moves towards both sides of the second conveyor belt 3 as the dividing line. During this movement, the scraper 42 cleans the adhesive surface of the roll. The attached debris is scraped off and carried to both sides of the first conveyor belt 2. Since the scraper 42 rotates continuously, it can continuously scrape the passing roll material and remove the adhesive layer on the surface of the roll material. As the roll material is gradually held and driven by the first conveyor belt 2 and the second conveyor belt 3, the roll material will gradually pass under the drive belts 4 on both sides of the second conveyor belt 3 away from the processing chamber 1. Since the two second conveyor belts 3 partially intersect, when the roll material moves to the end of the second conveyor belt 3, the roll material partially moves to the bottom of the other second conveyor belt 3, and then continues to be held by the other second conveyor belt 3 and the first conveyor belt 2, and the roll material continues to move.

[0062] More specifically, the continuing to move roll material will gradually move to the area below the drive belts 4 on both sides of the second conveyor belt 3 near the processing chamber 1. When the roll material enters the area below the drive belt 4, the drive belt 4 will drive the scraper 42 to scrape the roll material again. At the same time, since the two second conveyor belts 3 are staggered, when the roll material enters the area below the drive belt 4, the rotating scraper 42 can scrape the area of ​​the roll material that was originally far away from the second conveyor belt 3 of the processing chamber 1. This can remove the part that was not scraped when passing the first second conveyor belt 3, thus cleaning the roll material thoroughly and removing the debris and adhesive layer on the roll material.

[0063] Furthermore, when the roll material moves to the end of the first conveyor belt 2, it will move out from under the drive belt 4 and gradually fall into the processing chamber 1, where it will be crushed by the cutter 11. During this process, as the debris adhering to the surface of the roll material is scraped off, as well as the adhesive layer on the surface of the roll material, the debris can be prevented from damaging the cutter 11 during crushing. At the same time, it can be prevented that when the roll material fragments with adhesive layers stick to each other, the debris will be trapped inside the fragments and cannot be cleaned.

[0064] Furthermore, by using two sets of staggered intersecting second conveyor belts 3 to form a double-layer clamping conveyor structure with the first conveyor belt 2, and in conjunction with the drive belts 4 on both sides of the two sets of second conveyor belts 3 and the scraper 42, a two-stage progressive scraping of the roll material surface can be achieved. The first scraping removes the adhesive layer and hard debris such as cement slurry, concrete debris, and sand particles from the main area of ​​the roll material. The second scraping targets the areas of the roll material that were covered by the second conveyor belts 3 during the first scraping, thereby removing the adhesive layer and debris from the roll material surface. This avoids severe friction between hard debris and the cutter rollers and cutters 11 in the processing chamber 1 during the crushing process, fundamentally reducing the impact of the scraping process. The reduced wear and tear on the cutter 11 and the wear on the cutter roller extend the service life of the core crushing components. It also prevents the roll material fragments from sticking together due to residual adhesiveness, thus avoiding the trapping of impurities inside the sticky fragments. This results in the crushed roll material fragments being dispersed, allowing impurities to be fully exposed on the surface. Subsequent conventional cleaning methods can then thoroughly remove the impurities, solving the problems of incomplete cleaning and high impurity residue rates in traditional processes, significantly improving the cleanliness of the roll material fragments. Furthermore, it prevents impurities from affecting the physical properties and appearance quality of the recycled granules, thereby increasing the recycling rate of polyethylene resources.

[0065] As an embodiment of the present invention; a driven belt 5 is rotated by a roller on the third baffle 41 near the first end of the first conveyor belt 2, and a roller on the driven belt 5 is fixedly connected to a roller on the nearby drive belt 4;

[0066] A push plate 51 is fixed on the outer ring surface of the driven belt 5, and the push plate 51 is made of rubber material;

[0067] In this embodiment, the driven belt 5 is provided with an inclined plate 52 on the side facing the first end of the first conveyor belt 2, and the inclined plate 52 is fixed on the second baffle 31.

[0068] The inclined plate 52 is attached to the push plate 51 on the side closest to the push plate 51, and the bottom plane of the inclined plate 52 is flush with the bottom of the push plate 51.

[0069] In this embodiment, a circular groove is provided in the inclined plate 52; a rotating rod 53 is provided in the circular groove, and the rotating rod 53 rotates on the second baffle 31;

[0070] One of the rotating rods 53 extends into the inner ring of the second conveyor belt 3 and fits against the inner ring of the second conveyor belt 3; a gear is fixed on one side of the rotating rod 53 that extends into the inner ring of the second conveyor belt 3, and the inner ring of the second conveyor belt 3 has a toothed groove that meshes with the gear.

[0071] A limiting plate 54 is fixed on the rotating rod 53 located in the inner ring of the circular groove; adjacent rotating rods 53 are connected by a belt 55.

[0072] In practice, when the unfolded roll is placed at the beginning of the first conveyor belt 2 and moved by the first conveyor belt 2 and the second conveyor belt 3, the roll is driven by a ramp 52 located near the beginning of the first conveyor belt 2. The roll passes under the ramp 52. When the roll passes the ramp 52, the ramp 52 limits the roll, thus laying the roll flat on the first conveyor belt 2. Since the gear on the rotating rod 53 extending into the inner ring of the second conveyor belt 3 meshes with the tooth groove of the inner ring of the second conveyor belt 3, the rotating rod 53 will rotate during the rotation of the second conveyor belt 3. Since the rotating rods 53 are connected by belts 55, multiple rotating rods 53 can rotate clockwise, thereby driving the limiting plate to rotate. When the roll passes the limiting plate 54, the rotating limiting plate 54 will push the roll to fit against the first conveyor belt 2, thus preventing the roll from bulging in the middle. Subsequently, the limiting plate 54 will limit the roll, which will pass under the ramp 52.

[0073] Specifically, since the inclined plate 52 and the push plate 51 are attached, when the roll material passes through the inclined plate 52, the roll material will move to the bottom of the driven belt 5. During the rotation of the driven belts 5 on both sides, the push plate 51 will be driven to rotate. When the roll material moves to the bottom of the driven belt 5, the rotating push plates 51 on both sides will move along the surface of the roll material to both sides of the first conveyor belt 2, thereby flattening the roll material to both sides and avoiding bulges or even wrinkles in the middle of the roll material. At the same time, it can easily scrape off the debris on the surface of the roll material.

[0074] More specifically, the driven belt 5, which is fixedly connected to the drive belt 4, achieves synchronous linkage, driving the rubber push plate 51 to rotate in a cycle. The push plate 51 and the inclined plate 52 are closely fitted to form a connection. When the roll material passes under the driven belt 5, the push plates 51 on both sides move synchronously along the surface of the roll material to both sides of the first conveyor belt 2, realizing bidirectional flattening of the roll material and eliminating the surface wrinkles remaining after the roll material is unfolded. This allows every area on the surface of the roll material to come into contact with the subsequent scraper 42, avoiding the problem of dead corners scraped by the scraper 42 due to the unevenness of the roll material, and ensuring the efficiency and thoroughness of scraping off the adhesive layer and hard impurities.

[0075] As an embodiment of the present invention; an auxiliary frame is installed on the outer ring surface of the drive belt 4, and a pressure roller 45 is rotatably mounted on the side of the auxiliary frame away from the second drive belt 4;

[0076] In this embodiment, the auxiliary frame includes a fixing frame 43, and the fixing frame 43 is fixed inside the drive belt 4;

[0077] The fixed frame 43 has a sliding plate 44 that slides through a spring, and the pressure roller 45 rotates within the sliding plate 44;

[0078] In this embodiment, guide plates 46 are fixed on both sides of the slide plate 44, and the guide plates 46 are inclined to both sides respectively;

[0079] In this embodiment, the inner rings of the drive belt 4, the first conveyor belt 2, and the second conveyor belt 3 are all provided with filler plates 22;

[0080] The filling plate 22 of the inner ring of the first conveyor belt 2 is fixed on the first baffle 21; the filling plate 22 of the inner ring of the second conveyor belt 3 is fixed on the second baffle 31; the filling plate 22 of the inner ring of the drive belt 4 is fixed on the third baffle 41.

[0081] A pressure block 32 is fixed on the outer ring surface of the second conveyor belt 3.

[0082] During implementation, since the outer ring surface of the drive belt 4 is equipped with an auxiliary frame and a pressure roller 45, the drive belt 4 will also drive the auxiliary frame and pressure roller 45 to move during rotation. The pressure roller 45 will move along the surface of the roll material, so that the roll material can be flattened again. Then, the scraper 42 will be used to scrape it off. At the same time, when the pressure roller 45 passes over the debris, the pressure roller 45 will slide inside the fixed frame 43 due to the obstruction and compress the spring. This can prevent the pressure roller 45 from getting stuck with the debris. At the same time, since the slider is equipped with guide plates 46 on both sides, when the debris is higher than the pressure roller 45, the guide plates 46 will contact the debris. Then, the guide plates 46 will move along the debris and drive the slider to gradually slide into the fixed frame 43.

[0083] Specifically, since the first conveyor belt 2 and the second conveyor belt 3 are provided with filling plates 22, they can support the first conveyor belt 2 and the second conveyor belt 3, preventing the first conveyor belt 2 and the second conveyor belt 3 from being in a slack state and unable to clamp and pull the roll material. At the same time, since the second conveyor belt 3 has pressure blocks 32 fixed on its surface, the clamping effect on the roll material can be further improved.

[0084] Furthermore, since the drive belt 4 is also equipped with a filling plate 22, it can support the drive belt 4 and prevent the scraper 42 from pushing the drive belt 4 inward when it encounters resistance while scraping the surface of the roll material, thereby causing the scraper 42 to move and making it impossible for the scraper 42 to completely remove the debris and adhesive layer on the roll material.

[0085] Furthermore, the auxiliary frame linked to the drive belt 4 drives the pressure roller 45 to move synchronously with the scraper 42. The pressure roller 45 performs localized fine secondary flattening on the pre-leveled roll material, eliminating local protrusions and curling edges generated during the roll material conveying process, so that the roll material is completely pressed against the first conveyor belt 2, ensuring full contact between the scraper 42 and the roll material surface, and improving the scraping accuracy. At the same time, the filling plate 22 of the inner ring of the drive belt 4 can withstand the reaction force of the scraper 42 when scraping, preventing the drive belt 4 from being concave inward due to resistance, so that the scraper 42 always maintains a constant scraping force and is pressed against the roll material surface, eliminating the problem of incomplete scraping by the scraper 42 and residue of adhesive layer and debris due to belt body concavity.

[0086] As an embodiment of the present invention, a connecting plate 47 is fixed to the bottom of the two adjacent third baffles 41 located on the same side.

[0087] The connecting plate 47 has rounded corners on both sides.

[0088] In this embodiment, the ends of the third baffles 41 on both sides of each drive belt 4 are rotated by a rotating shaft with a brush layer 48, and the brush layer 48 is driven by a fifth motor.

[0089] Support plates 6 are fixed to the ends of the third baffle 41 located on the same side; two mounting plates 61 are fixed on the first baffle 21; a servo motor is installed at the bottom of the mounting plate 61.

[0090] The servo motor is equipped with a lead screw 62, which passes through the top support plate 6 and is screwed with the support plate 6.

[0091] During implementation, as the roll material moves out from the bottom of one drive belt 4 and gradually moves to the bottom of another drive belt 4, the connecting plate 47 can limit the roll material due to its presence, preventing the roll material from tilting up when it leaves one drive belt 4, thus preventing it from entering the bottom of the next drive belt 4.

[0092] Specifically, since the end of the third baffle 41 has a rotating brush layer 48, the fifth motor controls the brush layer 48 to rotate. The rotating brush layer 48 can clean the passing scraper 42 and pressure roller 45, thereby removing the debris adhering to the scraper 42.

[0093] More specifically, since the support plate 6 is fixed on the third baffle 41, and the screw 62 on the mounting plate 61 is screwed to the support plate 6, when processing rolls of different thicknesses, the servo motor is controlled to drive the support plate 6 to move up and down. The up and down movement of the support plate 6 will drive the third baffle 41 to move up and down, thereby driving the drive belt 4 and the second conveyor belt 3 to move up and down, thus adjusting according to the thickness of the roll.

[0094] Meanwhile, another processing method can be used when processing the roll material. That is, the drive belt 4 and the second conveyor belt 3 are lifted together by the lead screw 62. Then, the roll material is moved under the first second conveyor belt 3 by the first conveyor belt 2. Then, the drive belt 4 and the second conveyor belt 3 are controlled to move down, and the first conveyor belt 2 is controlled to stop rotating, so that the roll material can be scraped. After the scraping is completed, the drive belt 4 and the second conveyor belt 3 are controlled to move up. Then, the first conveyor belt 2 is controlled to move the roll material under the other second conveyor belt 3. Then, the second conveyor belt 3 and the drive belt 4 are controlled to move down to continue scraping the unscraped parts of the roll material.
