Description

Technical Field

[0001] The invention relates to the technical field of fiber reinforced cement board waste recycling, in particular to a fiber reinforced cement board waste recycling and reproducing device and a production method thereof. Background Art

[0002] Fiber reinforced cement board is a new type of building material, which is a mixture of cement, fine aggregate, fiber (such as glass fiber, polypropylene fiber, etc.) and other additives. This material significantly improves its strength, toughness and durability by adding fibers to the cement matrix. It has the functions of enhancing strength, improving toughness, waterproofing and moisture-proofing, and environmental protection. Therefore, it is widely used in many fields, including: construction industry, industrial engineering, infrastructure, water conservancy projects, home decoration, etc. Through these characteristics and wide applications, fiber reinforced cement board plays an important role in modern construction and industry, helping to improve the performance and safety of buildings. Fiber reinforced cement board residues refer to waste generated in the process of making and using fiber reinforced cement boards. These materials are usually a combination of cement, fiber and other components. Because of processing, construction or demolition, some scraps or waste may be generated.

[0003] In the existing fiber reinforced cement board waste recycling and reproduction process, the waste needs to be crushed twice. The first crushing is for the convenience of subsequent screening and processing, and the second crushing is to adjust the particle size of the material to meet the production needs. During the second crushing, some materials that already meet the production requirements are crushed again as a whole, which not only increases the complexity of the processing process, but also increases time and cost, resulting in a waste of resources and equipment. Grinding the material with a particle size that meets the production requirements again will increase fine particles and dust, which are difficult to recover in subsequent processing. The prior art has equipment that can recycle materials.

[0004] However, when feeding the crushing equipment, the feeding is not uniform enough. When the amount of material input in a certain time period is too large, the particle size of the material crushed in this time period will increase significantly, and when the amount of material input in a certain time period is small, the particle size in this time period will decrease significantly. The equipment in the prior art cannot adjust the particle size of the crushed material in a certain time period through the return material component.

[0041] A method for recycling and reproducing fiber reinforced cement board waste, comprising the following steps: S1, putting the collected fiber reinforced cement board residues into the first crushing box 1, driving the motor 12 to operate, and driving the coarse crushing parts to coarsely crush the residues; S2, the coarsely crushed residue falls into the second crushing box 2, and the crushing motor in the motor block 7 drives the second crushing roller 4 to operate and finely crush the coarsely crushed residue; S3, the finely crushed residue falls onto the filter plate 10 in the filter box 9, and while the driving motor 12 is operating, the first transmission member 13 and the second transmission member 15 drive the two sets of cam members 14 to operate, knocking the bottom of the filter box 9, and under the action of the spring expansion member 35, the filter box 9 drives the filter plate 10 and the receiving plate 11 to vibrate, and the filter plate 10 vibrates to screen the residue, and the residue of qualified size falls onto the receiving plate 11 and is discharged to the next recycling production step, and the residue of unqualified size remains on the filter plate 10; S4, while the driving motor 12 is operating, the cam member 14 drives the transmission mechanism to operate through the first rotating universal joint 16, so that the baffle 21 is intermittently switched. When the baffle 21 is flipped open, the residual material on the filter plate 10 falls into the collecting box 25. When the baffle 21 is flipped closed, the feeding is stopped. In this process, the coarse crushing member drives the spiral auger 27 to operate through the second rotating universal joint 30 and the fifth gear 29, and the residual material of unqualified size in the collecting box 25 is re-transported to the second crushing box 2 through the connecting box 31, and fine crushing is performed again. In this process, when there is a lot of material on the spiral auger 27, one end of the lever 37 will be squeezed, and the end of the lever 37 will be tilted up and the other end will be lowered, squeezing the connecting rod 39, so that the two mounting rods 42 are pulled down, and the upper ends of the two mounting rods 42 are close to each other, and the motor block 7 slides on the slide rail 8 to adjust the distance between the two second crushing rollers 4; S5.

[0042] When in use, the collected fiber reinforced cement board residues are put into the first crushing box 1, and the driving motor 12 is operated to drive the two first gears 5 to rotate, thereby driving the first crushing roller 3 to operate to coarsely crush the residues, and the second crushing roller 4 is driven to operate through the motor block 7 to finely crush the residues falling into the second crushing box 2. The finely crushed residues fall onto the filter plate 10 in the filter box 9. While the driving motor 12 is operating, the first transmission member 13 and the second transmission member 15 are driven to operate the two groups of cam members 14 to knock on the bottom of the filter box 9. Under the action of the spring telescopic member 35, the filter box 9 drives the filter plate 10 and the receiving plate 11 to vibrate. The filter plate 10 vibrates to crush the residues. After screening, the residues of qualified sizes fall onto the receiving plate 11, and the residues of qualified sizes screened out are collected through the inclined receiving plate 11, and rolled toward the discharge outlet, which is convenient for subsequent discharge, so as to carry out the next recycling and reproduction process, and the residues of unqualified sizes remain on the filter plate 10, and the residues of unqualified sizes roll toward the side of the collecting box 25. In this process, the cam member 14 drives the second gear 17 to rotate through the first rotating universal joint 16, and a second gear 17 drives another second gear 17 meshing with it to rotate, and drives the third gear 19 to rotate through the third transmission member 18, and a third gear 19 is meshed with a fourth gear 20, so that the baffle 21 is flipped open, and the release In addition to blocking the unqualified size residues on the filter plate 10, the residues on the filter plate 10 can fall into the collecting box 25. During the movement, the third gear 19 and the fourth gear 20 are gradually separated, and the third gear 19 continues to rotate. In this process, no gear is meshed and connected with the fourth gear 20. The elastic limiter 24 is engaged with the fixing block 23 and the connecting block 22 to limit the fourth gear 20. When another third gear 19 is meshed and connected with another fourth gear 20, the fourth gear 20 rotates, and the elastic limiter 24 releases the limit on the fourth gear 20, which can drive the baffle 21 to reset, flip and close, and stop feeding. In this process, the coarse crushing parts are connected through the second rotating universal joint 30 and the fifth The gear 29 drives the spiral auger 27 to operate, and the unqualified size residues in the collecting box 25 are transported back to the second crushing box 2 through the connecting box 31 for fine crushing again. In this process, when there is a lot of material on the spiral auger 27, one end of the lever 37 will be squeezed, and the end of the lever 37 will be tilted up and the other end will be lowered, squeezing the connecting rod 39, so that the two mounting rods 42 are pulled down, and the upper ends of the two mounting rods 42 are close to each other, and the motor block 7 slides on the slide rail 8 to shorten the distance between the two second crushing rollers 4 and reduce the amount of residual material returned. After the device is used, the card limiter 34 is toggled to release the limit on the filter screen 32, and the filter screen 32 is removed through the protrusion 33, which can be cleaned and replaced.
