[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0033] See also Figure 1-8 An asphalt waterproofing coil coating material recycling and processing system provided by an embodiment of the present invention includes a cooling bin 1, which is filled with coolant, and also includes: a conveying component, which is arranged in the cooling bin 1 and is used to immerse the coil in the coolant for conveying; a substrate 2, which is fixedly arranged in the cooling bin 1; a scraper component, which is arranged on the lower side of the substrate 2 and forms a scraper gap with the substrate 2, and the coil immersed in the coolant is arranged with the coating side facing the scraper component and continuously passing through the scraper gap.

[0034] Specifically, the cooling bin 1 is preferably in the shape of a bucket, with a discharge port provided at the lower end; the coolant may preferably be an organic carboxylate refrigerant or the like; the conveying assembly for conveying the coil is mainly divided into three steps: the first step is to connect the coil from outside the cooling bin 1 and feed it into the coolant; the second step is to keep the coil immersed in the coolant and convey it for a certain distance; the third step is to guide the coil out of the coolant and convey it outside the cooling bin 1; the substrate 2 is a hard plate, which is horizontally arranged below the coolant level, and the width of the substrate 2 is not less than the width of the coil; the coil immersed in the coolant for conveying is conveyed by sliding against the bottom surface of the substrate 2; the substrate 2 is detachably connected to the inner wall of the cooling bin 1, which is convenient for later maintenance; the scraper assembly continuously scrapes the coating material side of the coil passing through the scraper gap, and the scraper assembly has multiple scraping points for the coil along the conveying direction of the coil. In actual use of the present technical solution, the conveying component conveys the coiled material into the cooling bin 1 and immerses it in the coolant, so that the asphalt coating material cools quickly and becomes brittle, and the viscosity between the asphalt coating material and the fetal membrane is reduced. Then, when the coiled material passes through the scraper gap, the substrate 2 supports the coiled material, and the scraper component scrapes the coating material side of the coiled material, thereby making the brittle coating material easily separate from the fetal membrane of the coiled material and remain in the cooling bin 1, while the fetal membrane of the coiled material leaves the cooling bin 1 under the continued drive of the conveying component. In this process, the separation effect of the fetal membrane and the coating material is good, the separation is more complete, and the recovery rate of the asphalt material is high.

[0035] Compared with the prior art, an asphalt waterproofing roll coating recycling and processing system proposed in an embodiment of the present invention provides a conveying component to immerse the roll in the coolant in a cooling bin 1 for conveying, so that the asphalt coating is cooled and becomes brittle, and the viscosity between the asphalt coating and the fetal membrane is reduced. Then, when the roll passes through the scraper gap, the substrate 2 supports the roll, and the scraper component scrapes one side of the coating of the roll, thereby making the brittle coating easily separate from the fetal membrane of the roll. In this process, the separation effect of the fetal membrane and the coating is good, the separation is more complete, and the recovery rate of the asphalt material is high.

[0036] As a preferred technical solution of this embodiment, the conveying assembly includes two first rollers 3 immersed in the coolant and two second rollers 4 arranged near the upper end of the cooling bin 1, the two first rollers 3 are arranged on opposite sides of the substrate 2, and the lowermost side is arranged horizontally tangent to the bottom surface of the substrate 2, and the coil is arranged around the lower sides of the two first rollers 3. Specifically, the axial length of the first roller 3 is not less than the width of the coil, and the diameter of the first roller 3 is preferably 5-15 times the thickness of the coil; the second roller 4 is arranged above the first roller 3, and the coil is arranged around the upper side of the second roller 4. The two second rollers 4 are arranged opposite to each other, and one is used to connect the coil to the cooling bin 1, and the other is used to send the coil out of the cooling bin 1; the first roller 3 and the second roller 4 are rotatably connected in the cooling bin 1; the coil is driven by an external winding and unwinding device to pass through each first roller 3 and the second roller 4 in the above predetermined manner. In actual use, the coiled material is immersed in the coolant before passing through the first roller 3, that is, the coiled material is rapidly cooled, the coating material becomes brittle and the viscosity decreases. When this part of the coiled material passes through the curved surface of the first roller 3, the brittle asphalt coating material will crack under the bending action of the curved surface, and gradually become scaly. As a result, part of the coating material will directly separate from the fetal membrane and fall off, part of the coating material will continue to adhere to the fetal membrane with a narrow edge, and part of the coating material has a smaller area and is completely attached to the fetal membrane.

[0037] As the preferred technical solution of this embodiment, the scraper assembly includes a plurality of bases 5 which can be raised and lowered in the cooling bin 1, and a scraper 6 is arranged on the base 5. A driving assembly for driving the base 5 to reciprocate and rise and fall is arranged in the cooling bin 1. Specifically, the base 5 is preferably 2-4, which are equidistantly arranged on the lower side of the substrate 2 along the conveying direction of the coil; the lifting function of the base 5 can drive the scraper 6 to rise to cooperate with the substrate 2 to apply an impact load to the coil, thereby causing the coating material that is stubbornly attached to the coil but has become brittle to be broken and separated from the fetal membrane; after the driving assembly drives the base 5 to rise and the base 5 drives the scraper 6 to resist the coil, the driving assembly will not drive the base 5 to descend immediately, but will delay and stay for a period of time before descending, thereby keeping the scraper 6 in a state of scraping the coil for a period of time, ensuring the scraping function is realized, and the above process also enables the impact function of the scraper 6 on the coil to be realized.

[0038] As a preferred technical solution of this embodiment, sliders 7 are provided on two opposite sides of the base 5, and a slide groove 8 matching the slider 7 is provided on the inner wall of the cooling bin 1. Specifically, the slider 7 is raised and lowered in the slide groove 8, and the lifting range is limited, that is, the lifting range of the base 5 is limited. When the slider 7 rises to the highest position of the slide groove 8, the base 5 just drives the scraper 6 to resist the coil on the substrate 2.

[0039] As the preferred technical solution of this embodiment, the driving assembly includes a driving shaft 9 rotatably arranged in the cooling bin 1, a linkage rod 10 which can be raised and lowered synchronously extends from the side wall of the base 5, and a cam 11 which is fixedly arranged on the driving shaft 9 and is kept in contact with the linkage rod 10. Specifically, the driving shaft 9 is controlled by a servo motor and can rotate freely in forward and reverse directions; the driving shaft 9 is arranged on the lower side of the scraper assembly, the driving shaft 9 is horizontally arranged, and its axial direction is parallel to the direction in which the coil is conveyed on the lower sides of the two first rollers 3; the linkage rod 10 extends horizontally from the side wall of the base 5, and is axially parallel to the driving shaft 9 and is arranged directly above the driving shaft 9; the linkage rod 10 is kept in contact with the outer wall of the cam 11, so that when the driving shaft 9 drives the cam 11 to rotate, the linkage rod 10 reciprocates and rises and falls as the radius of the position in contact with the cam 11 changes.

[0040] Furthermore, the cam 11 is provided with a pull-back groove 26 that matches the linkage rod 10. Specifically, the linkage rod 10 is preferably a cylindrical rod, and the pull-back groove 26 is configured as an arc groove with an opening at one end and connected to the outer wall of the cam 11. The concave side of the arc groove corresponds to the rotation center of the cam 11, and the end away from the opening gradually approaches the rotation center of the cam 11; the inner wall width of the pull-back groove 26 matches the outer diameter of the linkage rod 10. For specific reference Figure 6 In actual use, when the cam 11 is driven by the driving shaft 9 to rotate counterclockwise, it can normally abut the linkage rod 10, so that the linkage rod 10 can reciprocate and rise and fall. When the cam 11 is driven by the driving shaft 9 to rotate clockwise, since the linkage rod 10 keeps abutting the outer wall of the cam 11, the linkage rod 10 can enter from the opening of the pull-back groove 26, and then slide into the depth of the pull-back groove 26, thereby further approaching the rotation center of the cam 11, that is, the linkage rod 10 drives the base 5 to further lower its height, and the base 5 drives the scraper 6 to descend away from the substrate 2, so that the scraping gap is fully expanded, thereby facilitating the initial loading of the coil.

[0041] As the preferred technical scheme of this embodiment, a fixed rod 12 is sleeved on the driving shaft 9, and a lifting sleeve 13 is sleeved on the fixed rod 12. A first elastic member 14 is connected between the upper end of the lifting sleeve 13 and the upper end of the fixed rod 12, and the extended end of the linkage rod 10 is fixedly connected to the lifting sleeve 13. Specifically, a sleeve is provided at the lower end of the fixed rod 12 and sleeved on the driving shaft 9. In addition, the lifting sleeve 13 sleeved on the fixed rod 12 is fixedly connected to the linkage rod 10 that only undergoes lifting movement, thereby fixing the fixed rod 12 relative to the cooling bin 1. In this way, the fixed rod 12 can preferably be fixedly connected to the inner wall of the cooling bin 1; a flange is provided on the upper end of the fixed rod 12, and the first elastic member 14 is preferably a spring, which is sleeved on the upper end of the fixed rod 12, and the upper and lower ends are respectively fixedly connected to the upper end flange of the fixed rod 12 and the lifting sleeve 13; the first elastic member 14 applies a thrust to the lifting sleeve 13, thereby causing the lifting sleeve 13 to drive the linkage rod 10 downward to remain against the outer wall of the cam 11.

[0042] In another embodiment of the present invention, the scraper 6 is rotatably arranged on the base 5, and the linkage rod 10 can be elastically raised and lowered relative to the base 5. The rotation of the scraper 6 is linked to the lifting and lowering of the linkage rod 10 relative to the base 5 through the energy storage component. A limit assembly for limiting the rotation of the scraper 6 is provided on the base 5. After the linkage rod 10 drives the base 5 to rise so that the upper end of the scraper 6 abuts against the coil, the linkage rod 10 continues to rise relative to the base 5 until it reaches the highest position to trigger the limit assembly to cancel the limit, and at the same time, the energy storage component The energy component drives the scraper 6 to rotate. Specifically, the base 5 is arranged in a U shape, and a convex rib opposite to the limiting component is arranged at the upper end of the middle part. The convex rib holds one side of the lower end of the limiting scraper 6, and can limit the scraper 6 in a vertical position in cooperation with the limiting component; the convex rib and the limiting component are arranged in sequence on the limiting side of the lower end of the scraper 6 along the conveying direction of the coil; the upper end of the vertical scraper 6 is arranged higher than the upper end of the base 5, so that when the base 5 rises to the highest position, the upper end of the scraper 6 can be against the coil. A slide plate 15 is provided in the base 5 so as to be liftable, and the upper end of the slide plate 15 is connected to the inner wall of the base 5 through a second elastic member 16; the second elastic member 16 prevents the slide plate 15 from rising relatively in the base 5, specifically: when the base 5 is limited by the slider 7 and the slide groove 8 and has not risen to the highest position, the linkage rod 10 is driven by the cam 11 to move upward, and the base 5 can be driven to move upward synchronously through the slide plate 15 and the second elastic member 16; and after the base 5 is limited by the slider 7 and the slide groove 8 and rises to the highest position, the linkage rod 10 can continue to move upward driven by the cam 11, but at this time, the slider 7 rises relatively in the base 5, and the second elastic member 16 is compressed. When the slide plate 15 rises relative to the base 5 and the second elastic member 16 is compressed, the energy storage component accumulates force and is used to drive the scraper 6 to rotate. At this time, the rotation direction of the scraper 6 under the action of the energy storage component is as follows: the upper end rotates in the direction opposite to the coil conveying direction; when the slide plate 15 is lowered and reset relative to the base 5, the linked scraper 6 rotates and resets to a vertical state; further, when the slide plate 15 is lowered to the lowest position relative to the base 5, the energy storage component reversely accumulates force at a certain angle to adapt to the limit component. The limit component cancels the limit when the linkage rod 10 rises to the highest position relative to the base 5, and restores the limit after the linkage rod 10 is lowered and reset relative to the base 5. In addition, the limit component restores the limit after the scraper 6 is reset to a vertical state.

[0043] As a preferred technical solution of this embodiment, the energy storage assembly includes a first gear 18 sleeved on the rotating shaft of the scraper 6 through a torsion piece 17, and a first rack 19 meshing with the first gear 18 is fixedly arranged on the skateboard 15. Specifically, the torsion piece 17 may preferably be a torsion spring, one end of which is fixedly connected to the rotating shaft of the scraper 6, and the other end is fixedly connected to the inner wall of the first gear 18; the elastic strength of the torsion piece 17 is much smaller than the elastic strength of the second elastic piece 16. When the second elastic piece 16 applies an elastic force to the skateboard 15 to reset the skateboard 15 to the lowest position relative to the base 5, the skateboard 15 is linked to the first gear 18 through the first rack 19 to rotate, so that the scraper 6 is reset to the vertical state, and further applies torsion to the torsion piece 17. At this time, the lower end of the scraper 6 is against the convex rib side. Thus, before the slide plate 15 descends and resets to the last height, the scraper 6 is first linked with the non-force-accumulating torque member 17 and the slide plate 15 through the first gear 18 and the first rack 19 to rotate and reset back to the vertical state. Then, when the slide plate 15 descends and resets to the last height, the slide plate 15 is linked with the limit assembly to restore the limit function, and the scraper 6 is already on the side where the limit assembly can act. The continued linkage between the scraper 6 and the slide plate 15 is reflected as the force accumulation of the torque member 17, thereby avoiding interference and achieving adaptation.

[0044] As a preferred technical solution of this embodiment, the limit assembly includes a swinging member 20 rotatably arranged on the base 5, a second gear 21 coaxially connected to the rotating shaft of the swinging member 20 is arranged in the base 5, the second gear 21 is meshed and connected with a second rack 22 slidably arranged in the base 5, a linkage frame 23 can be lifted and lowered in the base 5, the outer wall of the linkage frame 23 is hinged and linked with the second rack 22 through a connecting rod 24, and a sliding member 25 slidably embedded in the linkage frame 23 is fixedly arranged on the slide 15. Specifically, the swinging member 20 is arranged on the side opposite to the convex rib on the base 5, and the swinging member 20 rotates The stroke has a vertical position and a horizontal position. When it is in the vertical position, the free end can limit the rotation of the scraper 6 upward, and when it is in the horizontal position, the free end avoids the height of the lower end of the scraper 6 to cancel the limiting scraper 6; the linkage frame 23 has damping in the base 5 for relative lifting, that is, the linkage frame 23 is stationary in the base 5 when not subjected to external force; the sliding member 25 has a space that can move up and down in the linkage frame 23; the sliding member 25 rises and falls synchronously with the slide plate 15 and the linkage rod 10, and the sliding member 25 drives the linkage frame 23 to rise and fall synchronously only when it rises and falls relatively on the base 5 and approaches the upper and lower ends of the lifting stroke.In actual use of the present technical solution, when the linkage rod 10 is at the lowest position of the reciprocating lifting stroke, the slide plate 15 is at the lowest position in the base 5, and then the linkage scraper 6 is in a vertical state. At the same time, the linkage frame 23 is at the lowest position of the lifting stroke, and then through the linkage of the connecting rod 24, the second rack 22, and the second gear 21, the swing member 20 is in a vertical position to keep it limited on one side of the scraper 6; when the linkage rod 10 rises from the lowest position, the base 5 is first driven to rise as a whole through the slide plate 15 and the second elastic member 16, and the sliding member 25 does not move in the linkage frame 23; when the base 5 rises When the scraper 6 reaches the highest position, the upper end of the vertical scraper 6 is against the coil, and the scraper 6 can scrape the coating material of the coil passing through the scraping gap; then, the linkage rod 10 continues to rise, thereby driving the slide plate 15 to resist the first elastic member 14 in the base 5 to rise relatively. During this process, the slide plate 15 drives the first rack 19 and the first gear 18 to release part of the potential energy stored in the torque member 17. In addition, the slide plate 15 drives the sliding member 25 to move relatively upward in the linkage frame 23; then, the linkage rod 10 continues to rise, and starts to drive the first gear 18 through the slide plate 15 and the first rack 19. 18 rotates, the first gear 18 rotates relative to the rotating shaft of the scraper 6, so that the torsion piece 17 accumulates force, but because the linkage frame 23 is still stationary, the swinging piece 20 keeps the limited scraper 6; then, when the linkage rod 10 rises to a position close to the highest position, it starts to drive the linkage frame 23 to move upward through the slide plate 15 and the sliding piece 25, and the linkage frame 23 then drives the swinging piece 20 to rotate from the vertical position to the horizontal position through the connecting rod 24, the second rack 22, and the second gear 21; when the linkage rod 10 rises to the highest position, the swinging piece 20 is linked to the horizontal position, at this time, the potential energy stored in the torsion piece 17 is released to drive The scraper 6 rotates, and the upper end of the scraper 6 rotates rapidly in the opposite direction of the coil conveying direction, so that the scraper 6 scrapes the coating side of the coil for a period of time and then moves downward to ensure that the asphalt coating is peeled off the fetal membrane. In addition, the rapid rotation of the scraper 6 can drive the coolant to flow in a specified direction, that is, flow in the opposite direction of the coil conveying direction, and this part of the flowing coolant flows close to the coil, and then can impact the above-mentioned part of the coating that continues to adhere to the fetal membrane with a narrow edge, so that this part of the coating automatically detaches from the fetal membrane, further realizing the full separation of the coating and the fetal membrane.

[0045] Furthermore, when the linkage rod 10 begins to descend, under the action of the second elastic member 16, the base 5 is first kept at the highest position, and the slide plate 15 descends relative to the base 5, and then on the one hand, the first rack 19, the first gear 18, and the torque member 17 without power storage are used to link the scraper 6 to rotate, and on the other hand, the sliding member 25 is driven to move downward relative to the linkage frame 23, and the linkage frame 23 remains stationary; when the scraper 6 rotates to the vertical state, the sliding member 25 begins to push the linkage frame 23 downward, and then the linkage frame 23 drives the swing member 20 to switch from the horizontal position to the vertical position through the connecting rod 24, the second rack 22, and the second gear 21, so as to re-position the scraper 6; finally, the linkage rod 10 and the base 5 are synchronously moved downward as a whole to return to the lowest position of the reciprocating lifting. This cycle continues.

[0046] In addition, a supporting system is provided outside the cooling bin, that is, the discharge port of the cooling bin 1 is connected to a coating material collection device, which includes a vibrating screen arranged below the discharge port and a conveyor belt arranged adjacent to the vibrating screen; the vibrating screen is used to separate the coating material and the mixture of the freezing liquid into solid and liquid; the conveyor belt is used to convey the screen material after the solid-liquid separation; a recovery device is also provided below the vibrating screen, which includes a freezing liquid collector arranged at the bottom of the vibrating screen, a freezing liquid circulation pipeline connected to the freezing liquid collector and the freezing pool respectively, and a refrigeration device arranged on the freezing liquid circulation pipeline. The above is specific to the prior art and will not be repeated.

[0047] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
