Waste material recycling system

Abstract

A waste material recovery system includes a waste material lifting channel and an internally configured elevator, as well as a waste material recovery device. A guide pipe is installed on the waste material lifting channel, which connects to a mixer in the production line equipment. The waste material recovery device collects the scraped slurry from the mold and transports it to the elevator. As the elevator moves upward in the waste material lifting channel, a lifting door opens, allowing the recovered material to be returned to the mixer in the production line. This system not only recovers the material but also reuses it as raw material for the current production process without stopping the machine, eliminating the need for repeated collection of recovered material after production. This saves materials, reduces unnecessary operational steps, effectively lowers the labor intensity of operators, and improves overall operational efficiency.

Description

Technical Field

[0001] This invention relates to the field of gypsum block production equipment technology, specifically a waste material recycling system. Background Technology

[0002] Gypsum blocks are lightweight building gypsum products made primarily from building gypsum, through mixing with water, casting, and drying. In the current production process, gypsum slurry is typically poured into a mold from a cloth box, and then excess slurry is scraped off the mold by a scraper. Finally, the blocks are extruded, solidified, and removed. The scraping of excess slurry from the mold results in material waste. Current solutions involve setting up a recycling trough on one side of the mold to collect the scraped gypsum slurry. However, this requires recycling the slurry from the trough after production and using it as raw material for the next batch. This recycling process requires machine shutdown and consumes a significant amount of labor. Therefore, finding a way to recover the scraped slurry from the mold during production and use it as raw material for the current batch is a pressing issue. Summary of the Invention

[0003] The purpose of this invention is to provide a waste material recycling system, including a waste material lifting channel, an internally configured elevator, and a waste material recycling device. The waste material recycling device can collect the slurry scraped off the mold and transport it to the elevator. The elevator's vertical ascent can open the lifting door, sending the slurry to the mixer in the production line, thus realizing material recycling. Furthermore, the recycled material can be reused as raw material in the current production process without stopping the machine, solving the problems in the prior art.

[0004] The technical solution adopted by this invention to solve its technical problem is as follows: A waste material recycling system of this invention includes a vertically arranged waste material lifting channel, a vertically movable elevator installed within the waste material lifting channel, a vertical guide groove installed on the inner wall of the waste material lifting channel, a vertical sliding plate installed on the elevator that cooperates with the vertical guide groove, a winch installed at the top of the waste material lifting channel, and the winch's shaft connected to the elevator via a first connecting rope. When the winch is started, it drives the elevator to vertically lift and lower within the waste material lifting channel. A material leakage hole is opened on the side of the elevator away from the vertical guide groove, and a vertically movable lifting door is installed inside the material leakage hole. An inclined plate is installed at the bottom of the elevator, with one end of the inclined plate positioned inside the material leakage hole. A counterweight plate movable along its length is installed at the bottom of the inclined plate, and a second connecting rope is installed on the counterweight plate. A limiting rod that cooperates with the vertical guide groove is fixedly connected to the second connecting rope. The limiting rod is located at... On the upper side of the vertical sliding plate, a limiting block that cooperates with the limiting rod is installed in the vertical guide groove. The second connecting rope passes around the top of the hoist and connects to the lifting door. The weight of the lifting door is always greater than the vertical component of the weight of the counterweight plate. When the limiting rod contacts the limiting block, the hoist continues to move upward, and the lifting door can move upward to open the material leakage hole. At the same time, the counterweight plate can extend out of the material leakage hole and contact the inner wall of the residual material lifting channel. When the vertical sliding plate moves upward to contact the limiting rod, the lifting door... The door moves upward until the material leakage hole is fully open. A guide pipe connected to the interior is installed at the upper part of the residual material lifting channel. The elevator can move upward until the material leakage hole connects with the guide pipe. A feed inlet is also opened on the side of the elevator perpendicular to the lifting door. A through hole connected to the feed inlet is opened at the bottom of the residual material lifting channel. The residual material recycling system also includes a residual material recycling device. One end of the residual material recycling device is equipped with a discharge port corresponding to the through hole, which can send the recycled residual material into the through hole. A reinforcing rod is installed on the top of the elevator, and a lifting ring is installed on the reinforcing rod. The first connecting rope is fixedly connected to the lifting ring. Two second connecting ropes are connected between the lifting door and the counterweight plate. The two second connecting ropes are located on both sides of the lifting door and the counterweight plate, respectively. Connecting shafts are installed at both ends of the top of the elevator. Each connecting shaft is arranged parallel to the limit rod, and fixed pulleys that cooperate with the second connecting ropes are installed at both ends of each connecting shaft. The vertical sliding plate has guide holes that cooperate with the second connecting rope. The waste material recycling device includes a conveyor belt, one end of which is equipped with a waste material crushing box. A rotatable crushing roller is installed inside the waste material crushing box, and the crushing roller is located above the conveyor belt. A discharge port is installed at the bottom of the waste material crushing box, and the discharge port includes a fixed pipe located at the bottom of the conveyor belt. A movable pipe is installed on the fixed pipe, and a drive cylinder is installed on the fixed pipe. The piston rod of the drive cylinder is connected to the movable pipe. When the piston rod of the drive cylinder extends, the movable pipe can connect with the through hole.A proximity switch is installed at the bottom of the waste material lifting channel. The proximity switch is connected to the drive cylinder through a control circuit. When the elevator descends to connect with the feed inlet and the through hole, the proximity switch is triggered and sends a control signal to the drive cylinder, causing the moving tube to extend into the through hole. An elastic avoidance mechanism is also installed on the side wall of the elevator below the feed inlet. The elastic avoidance mechanism includes a vertical moving groove opened on the side wall of the elevator. An avoidance plate is installed in the vertical moving groove. Slider blocks that cooperate with the vertical moving groove are installed on both sides of the upper end of the avoidance plate. A spring is installed between the slider and the vertical moving groove. The spring always tends to push the slider to move upward to the top of the vertical moving groove. When the slider is located in the top of the vertical moving groove, the bottom end of the avoidance plate is located on the inner side of the side wall of the elevator, and the moving tube is located on the upper side of the avoidance plate. When the feed inlet on the elevator moves upward relative to the through hole, the avoidance plate can compress the spring and be located at the bottom of the moving tube.

[0005] The positive effects of this invention are as follows: The waste material recycling system of this invention includes a waste material lifting channel and an internally configured elevator, as well as a waste material recycling device. A guide pipe is installed on the waste material lifting channel, which can be connected to the mixer in the production line equipment. The waste material recycling device can collect the scraped slurry on the mold and transport it to the elevator. During the upward movement of the elevator in the waste material lifting channel, the lifting door can be opened, so that the material recovered inside can be sent back to the mixer in the production line. While realizing material recycling, the recovered material can also be reused as raw material for the current production without stopping the machine. It is not necessary to collect the recovered material again after the production is completed. This saves materials, reduces unnecessary operation steps, effectively reduces the labor intensity of operators, and improves the overall efficiency of the operation. Attached Figure Description

[0014] The waste material recycling system described in this invention, such as Figure 1 and Figure 2 As shown, it includes a vertically arranged waste material lifting channel 1, and a vertically movable elevator 2 is installed in the waste material lifting channel 1. The waste material lifting channel 1 serves as a vertical moving guide channel and also as the installation foundation of the overall device. The elevator 2 is used to hold the recovered waste material and realize the transfer of materials.

[0015] A vertical guide groove 3 is installed on the inner wall of the waste material lifting channel 1. A vertical sliding plate 4 that cooperates with the vertical guide groove 3 is installed on the elevator 2. A winch 5 is installed on the top of the waste material lifting channel 1. The shaft of the winch 5 is connected to the elevator 2 through a first connecting rope 6. When the winch 5 is started, it can drive the elevator 2 to move vertically up and down in the waste material lifting channel 1.

[0016] like Figure 3 and Figure 4 As shown, a material leakage hole 7 is provided on the side of the elevator 2 away from the vertical guide groove 3. A vertically movable lifting door 8 is installed inside the material leakage hole 7. When the lifting door 8 is lowered to the bottom of the material leakage hole 7, it can completely block the material leakage hole 7. When the lifting door 8 moves up, the material leakage hole 7 can be opened, thereby realizing the transfer of materials in the elevator 2 through the material leakage hole 7.

[0017] An inclined plate 9 is installed at the bottom of the elevator 2, with one end of the inclined plate 9 positioned inside the material leakage hole 7. The inclined plate 9 allows material inside the elevator 2 to leak out more easily through the material leakage hole 7, minimizing material residue within the elevator 2. A counterweight plate 10, movable along its length, is installed at the bottom of the inclined plate 9. The counterweight plate 10 extends beyond the inclined plate 9 and into the material leakage hole 7.

[0018] A second connecting rope 11 is installed on the counterweight plate 10. A limiting rod 12 that cooperates with the vertical guide groove 3 is fixedly connected to the second connecting rope 11. The limiting rod 12 is located on the upper side of the vertical slide plate 4. A limiting block 13 that cooperates with the limiting rod 12 is also installed in the vertical guide groove 3. The limiting block 13 can restrict the upward movement of the limiting rod 12 and the vertical slide plate 4.

[0019] The second connecting rope 11 passes around the top of the hoist 2 and connects to the lifting door 8. The lifting door 8, the limit rod 12, and the counterweight plate 10 are linked together through the second connecting rope 11. The weight of the lifting door 8 is always greater than the vertical component of the weight of the counterweight plate 10. That is, during the upward movement of the hoist 2, when the limit rod 12 is not in contact with the limit block 13, the lifting door 8 always blocks the leakage hole 7. At the same time, the counterweight plate 10 is always located at the bottom of the inclined plate 9 inside the hoist 2. When the limiting rod 12 contacts the limiting block 13, the elevator 2 continues to move upward. Since the limiting rod 12 cannot move upward, during the process of the elevator 2 driving the lifting door 8 upward, it is equivalent to pulling the second connecting rope 11 on the upper part of the lifting door 8, so that the lifting door 8 can move upward to open the material leakage hole 7. At the same time, the limiting rod 12, which moves downward relative to the elevator 2, also causes the counterweight plate 10 to move downward relative to the inclined plate 9 through the transmission of the second connecting rope 11. The counterweight plate 10 extends out of the material leakage hole 7 and contacts the inner wall of the residual material lifting channel 1, forming a relative seal between the bottom of the elevator 2 and the inner wall of the residual material lifting channel 1, preventing the material in the elevator 2 from entering between the elevator 2 and the residual material lifting channel 1.

[0020] A guide pipe 14, connected to the interior, is installed at the upper part of the waste material lifting channel 1. The elevator 2 can move upward to the discharge hole 7 and connect with the guide pipe 14. When the vertical sliding plate 4 moves upward to contact the limit rod 12, the elevator 2 rises to the highest position and stops rising. Figure 6 As shown, the lifting door 8 moves up until the material leakage hole 7 is fully open. The material leakage hole 7 is connected to the guide pipe 14. The counterweight plate 10 extends into the guide pipe 14, and the material in the elevator 2 can enter the guide pipe 14 and then enter the mixer of the entire production line as the raw material for this production.

[0021] A feed inlet 15 is provided on the side of the elevator 2 perpendicular to the lifting door 8. A through hole 16 that can communicate with the feed inlet 15 is provided at the bottom of the residual material lifting channel 1. The residual material recycling system also includes a residual material recycling device, which is located on one side of the mold and can recycle the slurry material scraped off by the scraper. One end of the residual material recycling device is equipped with a discharge port corresponding to the through hole 16, which can send the recycled residual material into the through hole 16.

[0022] When the aforementioned waste material recycling system performs recycling operations, the elevator 2 descends to the bottom of the waste material lifting channel 1. The feed inlet 15 is connected to the through hole 16. The waste material recycling device collects the excess material scraped off the mold and conveys it to the elevator 2 through the feed inlet 15. After the material in the elevator 2 reaches the set amount, the winch 5 drives the elevator 2 to move upward. During the upward movement, before the limit rod 12 moves upward to contact the limit block 13, the lifting door 8 keeps the leakage hole 7 closed to prevent leakage of material in the elevator 2. After the limit rod 12 moves upward to contact the limit block 13, the elevator 2 continues to move upward, and the lifting door 8 gradually opens until the vertical sliding plate 4 moves upward to contact the limit rod 12. Figure 6 As shown, at this point, the elevator 2 stops moving upwards, the lifting door 8 is fully open, and the material leakage hole 7 is connected to the guide pipe 14. Due to the inclined plate 9 at the bottom of the elevator 2, the material inside the elevator 2 will enter the guide pipe 14 through the material leakage hole 7, completing the material recycling. After the material inside the elevator 2 has been transferred, the winch 5 drives the elevator 2 to move downwards, the counterweight plate 10 gradually retracts back to the bottom of the inclined plate 9, and the lifting door 8 gradually closes the material leakage hole 7, finally falling to the bottom. Figure 2 The state shown is such that the residual material recovery device can transport the material on it back into the elevator 2.

[0023] Furthermore, in order to ensure the connection strength between the first connecting rope 6 and the hoist 2, a reinforcing rod 17 is installed on the top of the hoist 2, and a lifting ring 18 is installed on the reinforcing rod 17. The first connecting rope 6 is fixedly connected to the lifting ring 18.

[0024] Furthermore, to ensure the stability of the second connecting rope 11 when driving the lifting door 8 and the counterweight plate 10 to move up and down, and to avoid twisting during movement, two second connecting ropes 11 are connected between the lifting door 8 and the counterweight plate 10, with the two second connecting ropes 11 located on opposite sides of the lifting door 8 and the counterweight plate 10, respectively. To minimize the friction between the second connecting rope 11 and the hoist 2 during movement and to provide a certain guide for the second connecting rope 11, connecting shafts 19 are installed at both ends of the top of the hoist 2. Each connecting shaft 19 is arranged parallel to the limiting rod 12, and each end of the connecting shaft 19 is equipped with a fixed pulley 20 that cooperates with the second connecting rope 11.

[0025] Furthermore, the vertical sliding plate 4 is provided with a guide hole 21 that cooperates with the second connecting rope 11. The guide hole 21 not only plays a necessary guiding role for the movement of the second connecting rope 11, avoiding twisting or tangling of the second connecting rope 11, but also adjusts the relative installation position between the second connecting rope 11 and the vertical sliding plate 4, avoiding friction between the second connecting rope 11 and the inner wall of the waste material lifting channel 1 or the vertical guide groove 3, thereby effectively improving the service life of the second connecting rope 11.

[0026] Furthermore, such as Figure 7 As shown, the waste material recycling device includes a conveyor belt 22, which can be located on one side of the production line mold to allow the mold to directly scrape excess slurry from the mold onto the conveyor belt 22. One end of the conveyor belt 22 is equipped with a waste material crushing box 23, inside which a rotatable crushing roller 24 is installed, positioned above the conveyor belt 22. After recycling a certain amount of waste material, the material may solidify, making subsequent transportation or reuse inconvenient. The crushing roller 24 crushes the solidified material on the conveyor belt 22, allowing it to enter the feed inlet 15 for subsequent reuse.

[0027] A discharge port is installed at the bottom of the waste material crushing box 23. The discharge port includes a fixed pipe 25 located at the bottom of the conveyor belt 22. A movable pipe 26 is installed on the fixed pipe 25, and a drive cylinder 27 is installed on the fixed pipe 25. The piston rod of the drive cylinder 27 is connected to the movable pipe 26. When the piston rod of the drive cylinder 27 extends, the movable pipe 26 can connect with the through hole 16. After a certain amount of waste material is collected on the conveyor belt 22, the conveyor belt 22 rotates to transfer the waste material. At the same time, the piston rod of the drive cylinder 27 extends, so that the movable pipe 26 connects with the through hole 16. The material crushed by the crushing roller 24 can enter the elevator 2 sequentially through the fixed pipe 25 and the movable pipe 26 to achieve subsequent transfer.

[0028] Furthermore, in order to ensure that the drive cylinder 27 will drive the moving tube 26 to extend into the through hole 16 to realize the transfer of residual material when the feed port 15 on the elevator 2 descends to connect with the through hole 16, a proximity switch 28 is installed at the bottom of the residual material lifting channel 1. The proximity switch 28 is connected to the drive cylinder 27 through a control line. When the elevator 2 descends to connect with the feed port 15 and the through hole 16, the proximity switch 28 is triggered and sends a control signal to the drive cylinder 27, so that the moving tube 26 extends into the through hole 16.

[0029] After the remaining material in the moving pipe 26 is completely conveyed, the elevator 2 moves upward to convey the remaining material. To prevent the moving pipe 26 from making hard contact with the bottom side wall of the feed inlet 15 before it has completely exited the through hole 16, an elastic avoidance mechanism is installed on the side wall of the elevator 2 below the feed inlet 15. Figure 8As shown, the elastic avoidance mechanism includes a vertical moving groove 29 opened on the side wall of the elevator 2. An avoidance plate 30 is installed in the vertical moving groove 29. Slider blocks 31 that cooperate with the vertical moving groove 29 are installed on both sides of the upper end of the avoidance plate 30. A spring 32 is installed between the slider 31 and the vertical moving groove 29. The spring 32 always has the tendency to push the slider 31 to move upward to the top of the vertical moving groove 29. When the slider 31 is located in the top of the vertical moving groove 29, the bottom end of the avoidance plate 30 is located on the inner side of the side wall of the elevator 2. The moving tube 26 is located on the upper side of the avoidance plate 30. When the feed port 15 on the elevator 2 moves upward relative to the through hole 16, the avoidance plate 30 can compress the spring 32 and is located at the bottom of the moving tube 26.

[0030] If the moving pipe 26 does not completely exit the through hole 16 when the elevator 2 moves upward, the moving pipe 26 will restrict the upward movement of the clearance plate 30, causing the clearance plate 30 to compress the spring 32. This avoids hard contact between the moving pipe 26 and the side wall of the elevator 2, thereby extending the service life of the entire device. When the moving pipe 26 completely exits the through hole 16, the clearance plate 30 can move back to its original position under the elastic force of the spring 32, facilitating the next material conveying operation. Under the action of the spring 32, the clearance plate 30 can maintain close contact with the moving pipe 26 to prevent material leakage during the material conveying process.
