Description

Technical Field

[0001] This invention belongs to the field of polyurethane sponge recycling technology, specifically a polyurethane sponge recycling and regeneration device based on continuous degradation by biomass acid. Background Technology

[0002] In daily life, a large number of sponge products are used. However, recycling sponge products can pollute the environment. To reduce environmental pollution, polyurethane sponges are usually mixed, heated, and stirred with biomass acids (such as citric acid and malic acid, which are mixed to form an acid hydrolysate). The mixture is then separated by precipitation and centrifugation to separate the solid and liquid components. This effectively achieves the recycling and regeneration of polyurethane sponges while avoiding environmental pollution.

[0003] In existing polyurethane foam recycling devices, the reaction process is lengthy, and a large amount of reaction is usually carried out at once to improve efficiency. However, after the reaction is completed, sedimentation and centrifugation are required to separate the reaction products into solid and liquid components. The simultaneous sedimentation of a large amount of reaction mixture takes a long time, and the centrifugation time increases with each additional amount of mixture, thus reducing efficiency. Finally, the remaining impurities after centrifugation need to be washed. Using a single-unit structure leads to a decrease in efficiency and affects the continuous degradation effect.

[0004] Therefore, a polyurethane sponge recycling and regeneration device based on continuous degradation by biomass acid is proposed to solve the problems mentioned in the background technology. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention improves efficiency by using a combination of a rotation adjustment component and a discharge pipe to change the position of the discharge outlet. A drive motor rotates the drive gear; during rotation, the gears are engaged, and the fixed teeth are stationary. The drive gear and the outer limiting bracket move along the outside of the fixed teeth. A sealed bearing connects the upper end of the discharge pipe to the bottom outlet of the reactor, causing the drive gear to rotate along the bearing, thus changing the position of the discharge outlet. This allows for changing the discharge position. Finally, the waste is introduced into a centrifuge for centrifugation. The combination of the rotation adjustment component and four centrifuges effectively improves efficiency. Two centrifuges operate while two are being cleaned, further enhancing efficiency and preventing disruption to the reaction's continuity.

[0017] This invention, through the coordination of lifting components and discharge pipes, facilitates control of the discharge port position, preventing splashing during the descent of solid-liquid mixtures. While a rotating adjustment component is included, its rotation prevents the discharge port from being inserted into the centrifuge, leading to potential liquid splashing. By installing a telescopic push rod, the lower sliding frame and transmission plate can be adjusted for height. This adjustment synchronously adjusts the bottom tilting plate. Since the positioning block below the tilting plate is inserted into the positioning frame, the discharge port is simultaneously adjusted along the sealed telescopic pipe during lifting, allowing it to enter the centrifuge opening and preventing liquid splashing.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1 to 7 As shown, the present invention provides a polyurethane sponge recycling and regeneration device based on continuous degradation of biomass acid, including a reaction vessel 1. A rotation adjustment component is provided on the outer side of the lower end of the reaction vessel 1, and the rotation adjustment component is used to flexibly adjust the position of the discharge structure. A lifting component is provided on the right side of the rotation adjustment component, and the lifting component is used to adjust the height of the discharge port to avoid liquid splashing. The rotation adjustment assembly includes two sets of limiting discs 206, and a fixing tooth 207 is fixedly installed between the limiting discs 206. A drive gear 3 is meshed on the right side of the fixing tooth 207, and a drive motor 306 is installed on the top of the drive gear 3. A limiting bracket 305 is movably installed on the outside of the drive gear 3, and a welding frame 301 is installed at the bottom of the limiting bracket 305. A discharge pipe 9 is welded to the bottom of the welding frame 301, and a fixing sleeve 902 is welded to the outer side of the upper end of the discharge pipe 9. The inner side of the fixing sleeve 902 is fixedly connected to the opening at the bottom of the reactor 1 through a sealing bearing 901. The lifting assembly includes a telescopic push rod 4, and two sets of splicing plates 401 are fixedly installed on the outer sides of the upper and lower ends of the telescopic push rod 4. The splicing plates 401 are movably installed on the inner side of the welding frame 301. A sliding frame 405 is fixedly installed at the bottom of the output end of the telescopic push rod 4, and a transmission plate 5 is spliced ​​and installed on the right side of the sliding frame 405. An adjusting plate 504 is movably arranged in the middle of the transmission plate 5, and a fitting plate 506 is fixedly installed at the bottom of the adjusting plate 504. The fitting plate 506 is movably located on the inner side of the lower end of the transmission plate 5. A flipping plate 602 is movably arranged at the lower end of the transmission plate 5, and a positioning block 604 is fixedly installed on the left side of the lower end of the flipping plate 602. The lifting assembly includes a sealed telescopic tube 907, and the sealed telescopic tube 907 is embedded in the inner side of the lower end of the discharge pipe 9. A discharge port 908 is installed at the bottom of the sealed telescopic tube 907, and a positioning frame 910 is installed on the right side of the discharge port 908. The positioning block 604 is movably embedded in the inner side of the positioning frame 910.

[0022] Using the above scheme: the drive motor 306 drives the drive gear 3 to rotate. During the rotation, since the gear structure is in a meshed state and the fixed tooth 207 is in a fixed state, the drive gear 3 and the outer limiting bracket 305 will move along the outer side of the fixed tooth 207. Furthermore, since the upper end of the discharge pipe 9 connected to the bottom is connected to the discharge port at the bottom of the reactor 1 by a sealed bearing 901, the rotation of the drive gear 3 will drive the discharge pipe 9 to rotate along the sealed bearing 901, thereby changing the position of the discharge port 908 at the end of the discharge pipe 9. This method changes the discharge position, and finally, the waste is introduced into the centrifuge 7 for centrifugation. The centrifuge tubes 7 are designed for high-efficiency processing. By rotating the adjustment assembly and cooperating with the four sets of centrifuge tubes 7, efficiency can be effectively improved. The four sets of centrifuge tubes 7 can maintain two sets in operation and two sets in cleaning state, effectively improving efficiency and avoiding affecting the continuity of the reaction. By splicing and installing the telescopic push rod 4, the telescopic push rod 4 can be used to control the height adjustment of the lower sliding frame 405 and the transmission plate 5. During the adjustment, the bottom flip plate 602 will be adjusted synchronously. Since the positioning block 604 under the flip plate 602 is inserted into the inside of the positioning frame 910, the discharge port 908 will be adjusted in height along the sealed telescopic tube 907 during the lifting and lowering process and enter the opening of the centrifuge tube 7, avoiding the problem of liquid splashing.

[0023] like Figure 1 and Figure 2 As shown, several sets of connecting pipes 101 are fixedly installed on the top of the reactor 1, and a reducer 103 is installed on the top of the reactor 1 by bolts. A stirring motor 104 is installed on the top of the reducer 103 by bolts. A stirring paddle 105 is fixedly installed on the bottom of the reducer 103, and the stirring paddle 105 is movably located inside the reactor 1.

[0024] A sealing sleeve 903 is welded to the bottom of the fixed sleeve 902, and a control push rod 904 is fixedly installed at the bottom of the sealing sleeve 903 by bolts. The output of the control push rod 904 is provided with a piston rod 905, and a sealing piston 906 is installed on the top of the piston rod 905. The sealing piston 906 is tightly fitted to the inner side of the sealing sleeve 903. Several sets of limit guide rods 909 are fixedly installed on the top of the outer ring of the discharge port 908, and the limit guide rods 909 are movably located inside the lower end of the discharge pipe 9.

[0025] The outer fixed sleeve 902 of the reactor 1 has a jacket layer 2, and oil inlet and outlet pipes 201 are installed on one side of the upper end and the other side of the lower end of the jacket layer 2. Four sets of fixing plates 202 are welded and installed on the outer side of the jacket layer 2, and the bottom of the fixing plates 202 is fixedly connected to the jacket layer 2 through the reinforcing corner seat 204. The fixing bracket 203 is welded and installed at the end of the fixing plate 202. The limiting plate 206 is welded and fixedly installed above the jacket layer 2 with a limiting ring 205.

[0026] The above scheme allows for easy connection to various external additive pipelines via connecting pipe 101, facilitating material addition. Reducer 103, in conjunction with stirring motor 104, drives bottom stirring paddle 105 to rotate inside reactor 1, mixing the internally pulverized polyurethane sponge with biomass acid. Jacket 2 allows for the addition of high-temperature hot oil via inlet / outlet oil pipes 201, heating the internal solution. Fixing plate 202 and fixing bracket 203 are welded together to connect to the external load-bearing frame, maintaining stability. Reinforced corner brackets 204 increase connection strength. Limiting ring 205 has the same cross-sectional shape as sliding column 308, restricting its sliding. Sealing sleeve 903 and discharge pipe 9 are welded together, ensuring the internal channel allows for normal discharge of the solid-liquid mixture. Control push rod 904, connected to an external controller at the bottom, uses piston rod 905 to drive sealing piston 906 for height adjustment, sealing the internal channel by lifting, thus effectively controlling flow.

[0027] like Figures 3-6As shown, a connecting bracket 307 is welded to the top of the end of the limiting bracket 305 away from the drive motor 306, and a sliding column 308 is welded to the end of the connecting bracket 307. The sliding column 308 is slidably disposed inside the limiting ring 205. The left side of the welding frame 301 is fixedly connected to the discharge pipe 9 through the welding plate 302. Two sets of horizontal arc-shaped splicing grooves 303 are respectively opened on the front and back sides of the inner side of the welding frame 301, and two sets of vertical arc-shaped sliding grooves 304 are respectively opened on the front and back sides of the inner side of the welding frame 301, and the sliding grooves 304 are located below the splicing grooves 303.

[0028] The front and back of the splicing plate 401 are fixedly installed with splicing sliders 402, and the splicing sliders 402 are movably spliced ​​inside the splicing groove 303. Two sets of positioning holes 403 are opened through the right side of the splicing sliders 402. Two sets of stabilizing sliders 406 are installed on the front and back of the sliding frame 405 respectively, and the stabilizing sliders 406 are movably set inside the sliding groove 304. A slot 407 is opened on the right side of the sliding frame 405, and two sets of insertion holes 408 are opened through the top of the side of the sliding frame 405 away from the reactor 1. A connector 404 is installed on the top of the telescopic push rod 4.

[0029] A plug plate 501 is fixedly installed on the left side of the upper end of the transmission plate 5, and the plug plate 501 is embedded in the inner side of the slot 407. Two sets of triangular sliding grooves 503 are opened on the inner side of the middle part of the transmission plate 5, and the triangular sliding grooves 503 are located on the outer side of the adjusting plate 504. An auxiliary handle 505 is fixedly installed on the right side of the adjusting plate 504, and a shaft groove 502 is opened through the front of the lower end of the transmission plate 5.

[0030] Two sets of mounting shafts 601 are movably mounted on the front and back of the upper end of the flip plate 602, and a fitting groove 6 is provided on the top of the flip plate 602. The fitting groove 6 is located on the outside of the fitting plate 506, and an adjustment handle 603 is installed on the side of the flip plate 602 away from the discharge pipe 9.

[0031] Using the above solution: the limiting bracket 305 and the sliding column 308 can be connected by the connecting bracket 307. The sliding column 308 sliding along the inner side of the limiting ring 205 increases the stability of the sliding adjustment. The bottom welding frame 301 provides constraint for the inner structure. By splicing the splicing slider 402 into the inner side of the splicing groove 303 and fixing it with bolts along the positioning hole 403, the stability of the telescopic push rod 4 installation can be maintained. The output end of the telescopic push rod 4 is fixed to the sliding frame 405 with bolts. The stabilizing slider 406 of the sliding frame 405 will slide vertically along the sliding groove 304, increasing the stability of the sliding. The insert plate 501 is embedded in the slot. After the inner side of 407 is installed, the two sets of structures can be stably connected by locking the bolt structure on the inner side of the insertion hole 408. The triangular slide 503 is an inward triangular shape that can match the shape of the side of the adjustment plate 504 and slide stably up and down along the inner side. The auxiliary handle 505 makes it convenient for the user to grip and adjust. The shaft groove 502 at the bottom is used to restrict the movement of the mounting shaft 601 set on the inner side. The flip plate 602 can be flipped along the mounting shaft 601 to adjust the angle. The mounting shaft 601 can be disassembled with tools and installed with a threaded structure. The adjustment handle 603 is used to provide a grip for the user to easily control the flip plate 602 to flip and separate the positioning block 604.

[0032] like Figure 1 and Figure 7 As shown, four centrifuge cylinders 7 are arranged below the reactor 1, and the top opening of the centrifuge cylinder 7 corresponds to the position of the discharge port 908. A discharge valve 702 is fixedly installed at the bottom of the centrifuge cylinder 7, and four sets of support columns 701 are installed at the bottom of the centrifuge cylinder 7. A centrifuge motor 703 is bolted to the bottom of the centrifuge cylinder 7, and a connecting shaft 704 is provided at the output end of the centrifuge motor 703. An electric push rod 705 is fixedly installed inside the connecting shaft 704, and a guide cover 8 is fixedly installed at the top of the output end of the electric push rod 705. A movable frame 706 is welded to the bottom of the guide cover 8, and the movable frame 706 is movably arranged on the outside of the connecting shaft 704.

[0033] A movable rod 806 is fixedly installed on the top of the guide cover 8, and a limiting sleeve 805 is movably provided on the outer side of the movable rod 806. A connecting plate 804 is fixedly installed on the top of the limiting sleeve 805, and a bearing ring 803 is welded and installed on the outer side of the connecting plate 804. The outer ring of the bearing ring 803 is fixedly installed on the inner wall of the upper end of the centrifuge cylinder 7, and a metal filter frame 802 is fixedly installed on the bottom of the inner ring of the bearing ring 803. A smooth frame 801 is fixedly installed on the bottom of the metal filter frame 802, and the bottom of the smooth frame 801 is tightly fitted with the top edge of the guide cover 8.

[0034] The above solution employs a bottom discharge valve 702 to discharge internal solids and liquids. A centrifugal motor 703 drives the connecting shaft 704 to rotate. The connecting shaft 704 has a prismatic structure and an internally embedded electrically powered push rod 705. The push rod 705 is equipped with a battery and a remote control mechanism, allowing for control and adjustment of the device via an external controller. The push rod 705 controls the descent of the top-welded guide cover 8, creating a gap between it and the smooth frame 801. This ensures that internal residues can be discharged during subsequent cleaning. The metal filter frame 802, while rotating at high speed, effectively filters the solids and liquids. The mixture undergoes centrifugal separation, and the bearing ring 803 at the top assists the metal filter frame 802 in high-speed rotation. The limiting sleeve 805 is welded and installed through the connecting plate 804. The inner movable rod 806 and the limiting sleeve 805 have a multi-ribbed structure and can only slide up and down. The rotational kinetic energy of the centrifugal motor 703 can be transferred to the metal filter frame 802 through the connection between the connecting shaft 704, the movable frame 706, the guide cover 8, the movable rod 806 and the limiting sleeve 805, thereby achieving synchronous rotation and centrifugation. The external controller is a PLC controller, which is connected to each group of motors and push rods of the main device to ensure that the device can operate normally.

[0035] The working principle and usage process of this invention are as follows: First, connect the device to an external support frame. Then, add the material to be processed into the reactor 1 through the connecting pipe 101. Next, use the stirring motor 104 in conjunction with the reducer 103 to rotate the electrified stirring paddle 105. Simultaneously, inject flowing high-temperature hot oil into the reactor through the oil inlet / outlet pipes 201. The internal temperature of the reactor 1 is controlled at 140-200℃, the pressure at 0.5-1MPa, and the stirring time is 2 hours. Then, as needed, use the drive motor 306 to control the drive gear 3 to rotate. During the rotation, the meshing gear is electrified. The limiting bracket 305 and the bottom discharge pipe 9 rotate along the sealing bearing 901, ensuring that the discharge port 908 is adjusted to the opening at the top of the centrifuge cylinder 7 before stopping. Then, the sliding frame 405 and the transmission plate 5 are adjusted in height by the telescopic push rod 4, which simultaneously moves the tilting plate 602 and the positioning block 604 downwards, thereby pushing the discharge port 908 downwards along the limiting guide rod 909. After the discharge port 908 is inserted into the opening of the centrifuge cylinder 7, the height of the sealing piston 906 is adjusted by the control push rod 904 to keep the internal channel open. The solid-liquid mixture inside will then be discharged into the centrifuge cylinder. Inside cylinder 7, solid-liquid separation is achieved to a certain extent by using metal filter frame 802 and left and right sides of the stationary container. The separated liquid is directly discharged through discharge valve 702 for collection. Then, centrifugal motor 703 drives connecting shaft 704, movable frame 706, guide cover 8, movable rod 806 and limit sleeve 805 to rotate, thereby controlling the inner ring of bearing ring 803 and metal filter frame 802 to rotate synchronously at high speed. Finally, the remaining solid and liquid are separated by centrifugation. After separation, the liquid continues to be discharged. Then, the electric push rod 705 is adjusted remotely to adjust the guide cover 8 and smooth frame 806. The bottom of 1 separates, and the debris that accumulates on the inner wall will fall automatically. With the help of staff, water can be flushed from the top to the inside to completely flush out the waste and achieve the cleaning effect. When it is necessary to repair the telescopic push rod 4, the bolts inside the positioning hole 403 and the top of the sliding frame 405 can be removed to slide the telescopic push rod 4 out. At the same time, the fitting plate 506 can be separated from the fitting groove 6 by lifting the adjustment plate 504. After separation, the adjustment handle 603 can be grasped to drive the flip plate 602 to flip along the mounting shaft 601. After the positioning block 604 is separated from the positioning frame 910, it can be disassembled for repair.
