Description
Technical Field
[0001] This utility model relates to the field of gypsum board waste recycling technology, specifically an online crushing and recycling device for paper-faced gypsum board waste. Background Technology
[0002] In the construction industry, paper-faced gypsum board is a commonly used building material, generating a large amount of waste during its production and use. With the rapid development of the construction industry, the amount of paper-faced gypsum board waste is also increasing, making the efficient and environmentally friendly disposal of this waste an urgent problem to be solved.
[0003] Currently, the main methods for treating waste paper-faced gypsum board include landfill, incineration, and recycling. Landfill not only occupies a large amount of land resources but may also pollute the soil and groundwater; incineration produces a large amount of waste gas and residue, causing secondary pollution to the environment. While recycling is a more environmentally friendly method, existing recycling facilities have many problems in practical applications.
[0004] Existing waste recycling equipment for gypsum board paperboard performs poorly in terms of waste processing efficiency. Some devices employ simple crushing methods, resulting in an unstable and discontinuous crushing process, leading to slow waste processing speeds that cannot meet the demands of large-scale production. Furthermore, uneven stress on the waste during crushing easily leads to incomplete crushing, requiring secondary processing and increasing costs and time. Existing equipment also has shortcomings in terms of pulverization effectiveness. Some devices have poorly designed pulverizing components that fail to refine waste particles to the desired degree, affecting the recycling rate. Simultaneously, material accumulation and blockages are prone to occur during transportation, impacting the normal operation of the equipment. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0045] Please see Figure 1-5 An embodiment of this utility model provides an online crushing and recycling device for waste paper-faced gypsum board, including a mounting base plate 1, a feeding barrel 5, and a crushing cylinder 2.

[0050] The crushing cylinder 2 has a feed inlet at one end and a discharge outlet at the other end. The discharge outlet is located below the output end of the feed cylinder 5 to ensure that waste materials can smoothly enter the crushing cylinder 2.
[0051] The output end of the servo motor 7 extends into the transmission box 25 inside the cover 6 and is equipped with a drive wheel 20. Gears 17, 19 and 21 are evenly arranged on the outer side of the drive wheel 20. The inner wall of the transmission box 25 is provided with annular tooth grooves 18. Crushing roller shafts 22, 23 and 34 are evenly arranged inside the feed barrel 5. The connecting shafts of crushing roller shafts 22, 23 and 3 are respectively connected to gears 17, 19 and 21.
[0052] The side walls of crushing roller shaft 1 22, crushing roller shaft 23 and crushing roller shaft 3 24 are all uniformly provided with crushing teeth, and the crushing teeth of crushing roller shaft 1 22, crushing roller shaft 23 and crushing roller shaft 3 24 are arranged alternately.
[0053] The transmission box 25 is located inside the cover 6, forming a closed transmission space. It is made of aluminum alloy, which is lightweight and wear-resistant.
[0054] The drive wheel 20 is installed at the output end of the servo motor 7 and extends into the transmission housing 25. The surface is provided with a gear structure.
[0055] The inner wall of the transmission box 25 is provided with an annular toothed groove 18, which meshes with gear 17, gear 29 and gear 3 21 to ensure smooth transmission.
[0056] The inside of the feed barrel 5 is evenly equipped with three crushing rollers, namely crushing roller 1 22, crushing roller 2 23 and crushing roller 3 24, which are made of high carbon steel and have been heat-treated and hardened.
[0057] Each crushing roller shaft is connected to gear 17, gear 29 and gear 321 respectively to ensure synchronous rotation.
[0058] The side walls of crushing roller shaft 1 22, crushing roller shaft 23 and crushing roller shaft 3 24 are uniformly provided with crushing teeth. The crushing teeth are 20mm high and 15mm apart, and are staggered to achieve a high-efficiency crushing effect.
[0059] A servo motor 2 is provided at one end of the crushing cylinder 2, and the drive shaft of the servo motor 2 extends into the feeding chamber 12 of the crushing cylinder 2 and is connected to a feeding rod 8. Spiral blades 16 are evenly arranged on the outer side of the feeding rod 8, and grinding discs 9 are provided on the inner wall of the feeding chamber 12 between adjacent spiral blades 16.
[0060] The surface of the grinding disc 9 is uniformly provided with grinding protrusions, the volume of which is smaller than the volume of the crushing teeth of the first crushing roller shaft 22, the second crushing roller shaft 23, and the third crushing roller shaft 24.
[0061] The grinding disc 9 has a semi-circular structure and is located at the upper part of the feeding chamber 12, while the strip groove 11 is located at the lower part of the feeding chamber 12.
[0062] The crushing cylinder 2 is the core component of this invention. It is made of high-strength stainless steel to ensure sufficient wear resistance and impact resistance during the crushing process. A servo motor 15 is installed at one end of the crushing cylinder 2. The servo motor 15 adopts a high-precision servo control system, which can provide stable power output.
[0063] The drive shaft of servo motor 15 extends into the feeding chamber 12 of the crushing cylinder 2 through a sealing device and is connected to the feeding rod 8. The feeding rod 8 is made of wear-resistant alloy steel, and spiral blades 16 are evenly arranged on its outer side. The spiral blades 16 are arranged in a spiral shape, and the spacing between adjacent spiral blades 16 is 5 mm to ensure that the material can be evenly distributed during the feeding process.
[0064] Grinding discs 9 are provided on the inner wall of the feeding chamber 12 between adjacent spiral blades 16. The grinding discs 9 are made of high-hardness alloy and have grinding protrusions evenly distributed on their surface. The volume of the grinding protrusions is designed to be smaller than the volume of the crushing teeth of crushing roller shaft 1 22, crushing roller shaft 23, and crushing roller shaft 3 24 to ensure that the material is not over-crushed during the grinding process.
[0065] The grinding disc 9 has a semi-circular structure and is located at the top inside the feeding chamber 12. The advantage of this design is that after the material enters the feeding chamber 12, it undergoes preliminary grinding by the grinding disc 9, which improves the crushing efficiency.
[0066] The strip-shaped slot 11 is located at the lower part of the feeding chamber 12, with a width of 10 mm and a depth of 5 mm. The function of the strip-shaped slot 11 is to guide the ground material smoothly into the discharge chamber 10.
[0067] The crushing cylinder 2 below the feeding chamber 12 is also provided with a discharge chamber 10. A strip groove 11 is provided between the discharge chamber 10 and the feeding chamber 12. A screening screen 26 is installed on the inner side of the strip groove 11.
[0068] The bottom end of the crushing cylinder 2 is provided with a discharge port 3, and the discharge port 3 is connected to the material discharge chamber 10.
[0069] The other end of the bottom of the crushing cylinder 2 is provided with a discharge port 2 14, and the discharge port 2 14 is connected to the feeding chamber 12.
[0070] The crushing cylinder 2 is inclined, and the discharge port 1 3 is located at the lower end of the crushing cylinder 2, while the discharge port 2 14 is located at the upper end of the crushing cylinder 2.
[0071] The crushing cylinder 2 is tilted to ensure that the material can flow smoothly under the action of gravity.
[0072] The feeding chamber 12 is located above the crushing cylinder 2, and the crushing cylinder 2 below it has a discharge chamber 10. The feeding chamber 12 and the discharge chamber 10 are connected by a strip-shaped groove 11. A screening screen 26 is installed on the inner side of the strip-shaped groove 11. The function of the screening screen 26 is to screen the ground material. The qualified material enters the discharge chamber 10 and is discharged, while the unqualified material continues to be conveyed forward and ground inside the feeding chamber 12.
[0073] The bottom of the crushing cylinder 2 is provided with a discharge port 3, which is connected to the material discharge chamber 10. The discharge port 3 is mainly used to discharge the fine particles after crushing and screening. The other end of the bottom of the crushing cylinder 2 is provided with a discharge port 14, which is connected to the feeding chamber 12. The discharge port 14 is mainly used to discharge larger particles that have not met the crushing requirements, so as to carry out secondary crushing or recycling.
[0074] The crushing cylinder 2 is inclined, with discharge port 1 3 located at the lower end of the crushing cylinder 2 and discharge port 2 14 located at the upper end of the crushing cylinder 2. This design utilizes gravity to allow fine particles of material to be discharged smoothly through discharge port 1 3, while larger particles are discharged through discharge port 2 14, thereby achieving material classification.
[0075] When this application embodiment is used,
[0076] Waste feeding:
[0077] The waste paper-faced gypsum board to be processed enters the feed tank 5 through the feed port on the top of the cover 6. The feed tank 5 is fixed by the support column 4 on the mounting base plate 1 to ensure stable reception of waste.
[0078] Primary breakage:
[0079] Servo motor 7 is started, and its output drives the drive wheel 20 inside the transmission housing 25 to rotate. As the drive wheel 20 rotates, gears 17, 19, and 21 on its outer side mesh with the annular toothed groove 18 on the inner wall of the transmission housing 25, thereby driving the crushing roller shafts 22, 23, and 24, which are connected to gears 17, 19, and 21 respectively, to rotate synchronously. Because the crushing teeth on the side walls of the three crushing roller shafts are staggered, the waste gypsum board is subjected to the squeezing and shearing action of the crushing roller shafts within the feed hopper 5, and is initially crushed into larger particles.
[0080] Waste material is conveyed to the crushing cylinder:
[0081] The waste material, after primary crushing, falls from the output end of the feed hopper 5 and enters the feed inlet of the crushing cylinder 2 located below it. The crushing cylinder 2 is fixed to the mounting base plate 1 by the support column 13.
[0082] Feeding and grinding:
[0083] Servo motor 2 (15) is started, and its drive shaft drives the feeding rod 8 to rotate. The spiral blades 16 on the outer side of the feeding rod 8 rotate accordingly, propelling the waste material entering the feeding chamber 12 forward. During this process, the waste material passes over the grinding disc 9 located above the inner wall of the feeding chamber 12, between adjacent spiral blades 16. The grinding protrusions on the surface of the grinding disc 9 further grind the waste material. Since the volume of the grinding protrusions is smaller than the volume of the crushing teeth on the crushing roller shaft, it can finely grind the waste material, further refining the waste particles.
[0084] Screening and grading discharge:
[0085] The ground waste continues to be propelled forward by the spiral blades 16 within the feeding chamber 12. When it reaches the strip-shaped slot 11 below the feeding chamber 12, the fine particles that meet the aperture requirements of the screening mesh 26 will fall into the discharge chamber 10 through the strip-shaped slot 11. Due to the inclined setting of the crushing cylinder 2, these fine particles are discharged from the discharge port 3 located at the lower end of the crushing cylinder 2 under the action of gravity. The larger particles that do not pass through the screening mesh 26 and do not meet the requirements continue to be conveyed forward by the spiral blades 16 within the feeding chamber 12, and are ground again by the grinding disc 9 until they meet the requirements and fall into the discharge chamber 10 through the strip-shaped slot 11 or are discharged from the discharge port 14 located at the upper end of the crushing cylinder 2 for secondary crushing or recycling.
