Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of plastic recycling, and particularly relates to a hot-melt processing and recycling device for modified plastics. BACKGROUND

[0002] In the field of recycling of modified plastics, the hot-melt processing process is a core link for realizing regeneration of high polymer materials, and the performance of the device directly affects the physical and mechanical properties of the recycled materials and the production efficiency. The current mainstream hot-melt recycling device still has the following technical bottlenecks in engineering application.

[0003] During the hot-melt process of plastic raw materials, the solid-liquid two-phase materials are in a mixed state, and the mixing and retention of molten polymers and solid particles reduce the heat transfer coefficient of the heat source to the unmelted particles, prolong the hot-melt retention time of the materials, and restrict the continuous production efficiency; at the same time, the internal heat loss rate of the device is relatively high, and the heat utilization efficiency of the device is generally low, which not only causes energy waste, but also forms a potential thermal safety risk due to the abnormal increase of the temperature of the outer wall of the device.

[0004] When the plastic particles after crushing enter the hot-melt bin, if the feeding port is not well sealed, toxic smoke and dust generated during the hot-melt process can easily diffuse to the outside through the feeding channel, threatening the health of the operators. SUMMARY

[0013] As another preferred technical solution of the present invention: the inner wall of the hot melt chamber is provided with a guide groove, the surface of the bracket is slidably connected with a guide frame, the top of the guide frame is slidably connected to the inside of the guide groove, the bottom of the guide frame is fixedly connected with a stirring plate, the surface of the stirring plate is provided with openings in a ring array, and a turntable is rotatably connected inside each opening.

[0014] As another preferred technical solution of the present invention: the staggered flip-top assembly includes a first cover plate symmetrically and rotatably connected to the top of the bracket, a cylinder rotatably connected below the first cover plate and located on the inner wall of the bracket, a sliding groove is provided inside the first cover plate, the telescopic end of the cylinder slides in cooperation with the sliding groove of the first cover plate, a support arm is rotatably connected to the wall of the telescopic end of the cylinder, a second cover plate is symmetrically and movably connected to the bracket, the end of the support arm away from the cylinder is rotatably connected to the upper surface of the second cover plate, and a feed port is provided in the middle of the bracket.

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0039] It is understood that the terms “first,” “second,” etc., used in this application may be used herein to describe various elements, but unless otherwise stated, these elements are not limited by these terms. These terms are used only to distinguish one element from another.

[0040] like Figures 1 to 4 , Figure 7 As shown, in one embodiment, a hot-melt processing and recycling device for modified plastics is proposed, including a crusher 1, a shell 2, and a hot-melt chamber 3. The shell 2 is installed at the bottom of the crusher 1, and the hot-melt chamber 3 is rotatably connected to the inside of the shell 2. The device also includes:

[0041] Separation component 4 is disposed inside the outer shell 2. Separation component 4 includes a furnace 41 fixedly connected to the bottom of the inner cavity of the hot melt chamber 3. A hot air blower 43 is installed at the bottom of the inner cavity of the furnace 41. A baffle 42 is fixedly connected to the top of the furnace 41. A support 44 is fixedly connected to the bottom of the crusher 1 and inside the hot melt chamber 3. A sleeve 45 is symmetrically fixedly connected to the bottom of the support 44. The inner layer of the sleeve 45 is in contact with the outer wall of the furnace 41. The outer layer of the sleeve 45 is in contact with the inner wall of the hot melt chamber 3. An arc groove 46 is opened on the side wall of the sleeve 45. A rotating shaft 47 is rotatably connected inside the sleeve 45. A precipitation hole 48 adapted to the rotating shaft 47 is opened on the surface of the hot melt chamber 3.

[0042] Temperature equalization component 5 is installed inside the outer shell 2 to keep the temperature of the hot melt plastic inside the hot melt chamber 3 uniform;

[0043] The staggered flip-top assembly 6 is located inside the outer casing 2 and is used to isolate the fumes from the hot-melt plastic inside the hot-melt chamber 3.

[0044] In practical application, after the plastic raw material is fed into the crusher 1, it will be crushed into particles by the crusher 1 and enter the furnace 41 through the filter hole 101. At this time, the hot air blower 43 will start and heat the plastic particles. The hot air is guided by the wind force and the baffle 42, so that the plastic particles are in a state of vertical circulation inside the furnace 41. When the crusher 1 is running, the hot melting chamber 3 is rotating inside the outer shell 2. The rotation of the hot melting chamber 3 will drive the furnace 41 to rotate together. After the plastic particles inside the furnace 41 are melted, they will stick to the inner wall of the furnace 41 and flow to the outside of the furnace 41 under the action of centrifugal force when the furnace 41 is rotating. Thus, the plastic that is already in a liquid state is no longer stored inside the furnace 41, ensuring that the heat of the hot air blower 43 is efficiently applied to the solid plastic.

[0045] When the liquid plastic flows into the hot melt chamber 3 through the surface of the furnace 41, it will flow into the precipitation holes 48 on the surface of the hot melt chamber 3 due to the centrifugal force caused by the rotation of the hot melt chamber 3. The rotation of the hot melt chamber 3 will cause the rotating shaft 47 to be inserted into each precipitation hole 48. The arc groove 46 will squeeze the plastic adhering to the inner wall of the hot melt chamber 3, so that the liquid plastic enters the precipitation hole 48 faster and squeezes the liquid plastic inside the precipitation hole 48 outward.

[0046] like Figure 3 As shown, in a preferred embodiment of the present invention, the baffle 42 is conical, the hot air blower 43 is perpendicular to the concave center of the baffle 42, the hot air blower 43 blows hot air vertically upward, and the arc groove 46 is arc-shaped, so that the distance between the side wall of the casing 45 and the inner wall of the hot melt chamber 3 becomes smaller.

[0047] In practical applications, the conical shape of the baffle 42 allows the hot air blown upward by the hot air blower 43 to circulate and store heat inside the furnace 41, preventing heat from escaping outward through the top of the furnace 41. The design of the baffle 42 also prevents plastic particles that fall inside the furnace 41 from being blown outward from the top of the furnace 41, thus ensuring that the plastic particles can be efficiently melted inside the furnace 41.

[0048] like Figure 4As shown, in another preferred embodiment of the present invention, the outer wall of the hot melt chamber 3 is fixedly connected with toothed rings 301 arranged in a ring array, the inner wall of the outer shell 2 is rotatably connected with a transmission gear 302, the transmission gear 302 and the crusher 1 are connected by a transmission belt 303, the outer shell 2 and the hot melt chamber 3 are slidably fitted with a slip ring 410, the slip ring 410 and the transmission gear 302 are connected by a support rod 49, and the support rod 49 is eccentrically rotatably connected to the outer wall of the transmission gear 302.

[0049] In practical application of this invention, when the crusher 1 is operating, it will drive the transmission gear 302 to rotate together via the transmission belt 303. At this time, because the support rod 49 rotates eccentrically on the outer wall of the transmission gear 302, the transmission gear 302 will drive the slip ring 410 to slide vertically back and forth between the outer shell 2 and the hot melt chamber 3 via the support rod 49. During the downward sliding process of the slip ring 410, because hot melted liquid plastic continuously flows out of the outer wall of the hot melt chamber 3 through the precipitation hole 48, the downward sliding of the slip ring 410 enables the liquid plastic to flow out downward faster.

[0050] like Figure 2 As shown, in another preferred embodiment of the present invention, a sloping base plate 201 is fixedly connected to the bottom of the inner cavity of the outer shell 2, and a discharge port 202 is opened on the wall of the outer shell 2 at the lower position of the sloping base plate 201.

[0051] In practical application, the liquid plastic dripping from the outer wall of the hot melt chamber 3 onto the inclined substrate 201 will flow towards the discharge port 202 due to the influence of the inclined surface at the top of the inclined substrate 201, so that the hot melted liquid plastic flows out from the discharge port 202, which is convenient for workers to collect.

[0052] like Figures 5 to 7 As shown, in another preferred embodiment of the present invention, the inner wall of the hot melt chamber 3 is provided with a guide groove 51, the surface of the support 44 is slidably connected to a guide frame 52, the top of the guide frame 52 is slidably connected to the inside of the guide groove 51, the bottom of the guide frame 52 is fixedly connected to a stirring plate 53, the surface of the stirring plate 53 is provided with openings 54 in a ring array, and a turntable 55 is rotatably connected inside each opening 54.

[0053] In practical application, the hot melt chamber 3 rotates and drives the guide groove 51 on its inner wall to rotate together. At this time, because the top of the guide frame 52 slides on the guide groove 51 and the middle part of the guide frame 52 slides on the surface of the support 44, the guide groove 51 drives the guide frame 52 to slide vertically back and forth on the surface of the support 44 during the rotation of the hot melt chamber 3. During the sliding process, the guide frame 52 drives the stirring plate 53 to slide together.

[0054] When the stirring plate 53 slides downward inside the hot melt chamber 3, the liquid plastic inside the hot melt chamber 3 will cause the turntable 55 to flip and open, so that the liquid plastic inside the hot melt chamber 3 floats above the stirring plate 53 through the opening 54.

[0055] When the stirring plate 53 drives the opening 54 to slide upward inside the hot melt chamber 3, the turntable 55 is no longer squeezed by the liquid plastic at the bottom of the stirring plate 53 and flips to close. As the stirring plate 53 and the opening 54 slide upward together, the liquid plastic deposited at the bottom of the hot melt chamber 3 is lifted upward, so that the liquid plastic can maintain a uniform temperature inside the hot melt chamber 3.

[0056] like Figure 9 and Figure 10 As shown, in another preferred embodiment of the present invention, the staggered flip-top assembly 6 includes a first cover plate 61 symmetrically rotatably connected to the top of the bracket 44. A cylinder 63 is rotatably connected to the lower part of the first cover plate 61 and located on the inner wall of the bracket 44. A sliding groove 62 is provided inside the first cover plate 61. The telescopic end of the cylinder 63 is slidably engaged with the sliding groove 62 of the first cover plate 61. A support arm 64 is rotatably connected to the wall of the telescopic end of the cylinder 63. A second cover plate 65 is symmetrically and movably connected to the bracket 44. The end of the support arm 64 away from the cylinder 63 is rotatably connected to the upper surface of the second cover plate 65. A feed port 66 is provided in the middle of the bracket 44.

[0057] In practical application of this invention, when the plastic particles that have been crushed inside the crusher 1 need to enter the melting step, the operator operates the cylinder 63 in the extended state to retract. When the cylinder 63 retracts, its telescopic end will slide inside the slide groove 62 of the first cover plate 61. At this time, because the two first cover plates 61 are attracted by magnetic blocks, the first cover plates 61 will not easily flip over. During the retraction process, the cylinder 63 will rotate around the side wall of the support 44. During the retraction process of the telescopic end of the cylinder 63, it will drive the second cover plate 65 to move together through the support arm 64. When the telescopic end of the cylinder 63 slides to the end inside the slide groove 62, the two second cover plates 65 will stick together due to magnetic attraction and form a shield for the feed port 66, so that the heat inside the hot melt chamber 3 is shielded by the second cover plate 65 below it.

[0058] When the extension end of cylinder 63 slides to the end inside the slide groove 62, as cylinder 63 continues to retract, the retraction of cylinder 63 will cause the first cover plate 61 to flip open, allowing the crushed plastic particles inside the crusher 1 to fall downwards onto the second cover plate 65 through the filter hole 101.

[0059] Similar to the above principle, when the cylinder 63 extends, the two first cover plates 61 will block the filter holes 101, and the second cover plate 65 will flip open, allowing the plastic particles falling on the second cover plate 65 to fall into the interior of the furnace 41 through the feed port 66.

[0060] By staggering the closing of the first cover plate 61 and the second cover plate 65, the heat inside the hot melt chamber 3 can be blocked by the second cover plate 65 when the plastic inside the crusher 1 passes through the filter hole 101 and the first cover plate 61, preventing it from escaping upwards. When the second cover plate 65 flips open to allow plastic particles to fall into the hot melt chamber 3, the first cover plate 61 can close to prevent toxic gases inside the hot melt chamber 3 from spreading to the outside through the filter hole 101 and causing safety hazards to personnel around the crusher 1.

[0061] like Figure 1 , Figure 9 and Figure 10 As shown, in another preferred embodiment of the present invention, the bottom of the crusher 1 is provided with a filter hole 101, the diameter of the first cover plate 61 is equal to that of the filter hole 101, the first cover plate 61 is attached to the lower surface of the crusher 1 when the cylinder 63 extends, and the second cover plate 65 is attached to the upper surface of the support 44 when the cylinder 63 retracts.

[0062] like Figure 9 and Figure 10 As shown, in another preferred embodiment of the present invention, magnetic blocks are installed on opposite sides of the two first cover plates 61, and magnets are installed on opposite sides of the two second cover plates 65.

[0063] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
