Description

Technical Field

[0001] The present invention relates to the technical field of grouting molding, and particularly to a method for forming, processing and preparing a coal gangue sound insulation board. Background Art

[0002] The coal gangue sound insulation board forming and processing device is an industrial device specifically used to convert coal gangue into a sound insulation board. Coal gangue is a by-product generated during coal mining, usually containing a certain proportion of inorganic minerals. The raw materials of the coal gangue sound insulation board include coal gangue particles, cement, reinforcing fibers and auxiliary agents. These materials are uniformly mixed with water to form the raw material slurry of the coal gangue sound insulation board.

[0003] The coal gangue sound insulation board can ensure more uniform distribution of the mixture in the mold through grouting molding. By injecting the slurry into the mold, it is easier to control the distribution of the slurry, avoiding problems such as voids and uneven distribution. Moreover, grouting molding can help improve the density of the board.

[0004] The full-automatic high-pressure grouting molding production line with the Chinese patent application number 200420115826.4. It uses an oil pressure system to lock and unlock the mold. The pressure slurry is pressed into the mold cavity through a slurry pressurizing system, and the slurry intake process is completed relying on the filtering and water absorption capacity of the mold. For products that need to drain the slurry, the mold can be installed on a tiltable rack to drain the slurry by tilting. It accelerates the slurry intake speed through a vacuum system or adsorbs the product on a certain mold so that the product can move simultaneously with the mold during demolding. Through the compressed air system, the water absorbed by the mold from the slurry is blown back between the product and the mold to separate the product from the mold.

[0005] During the use of the existing coal gangue sound insulation board forming and processing device, the solidification efficiency of the slurry inside the mold is relatively low, and it takes a longer time to complete the solidification process, resulting in an extended production cycle and affecting production efficiency and production capacity. Summary of the Invention

[0034] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0035] 1. The present invention can drive the forming mechanism to move by setting a rotating mechanism. During the operation of the rotating mechanism, the output shaft of the first reduction motor drives the small gear to rotate, the small gear drives the large gear and the rotating rod to rotate, the rotating rod drives the turntable to rotate, and the turntable drives several vibration mechanisms and the forming mechanism to rotate synchronously. The angle sensor detects the rotation angle of the rotating rod, and when the set angle is reached, the first reduction motor is turned off. During the rotation of the turntable, the support rod and the universal wheel are driven to slide on the top of the base to prevent the turntable from shaking during rotation.

[0036] 2. The present invention can prepare the raw materials of the coal gangue sound insulation board into a slurry and transport it into the forming mechanism by setting a grouting mechanism. The output shaft of the second reduction motor drives the mixing rod to rotate, the mixing rod drives the dispersing frame and the mixing frame to rotate synchronously. The dispersing frame breaks up the agglomerated raw materials, and the mixing frame stirs and mixes the raw materials. During the stirring process, the external water source enters the annular pipe through the first solenoid valve and is evenly sprayed into the inner cavity of the mixing tank through the one-way nozzle, so that the water and the raw materials are mixed into a slurry. The output shaft of the second cylinder drives the sealing ring away from the surface of the mixing rod, so that the mixing assembly and the conveying cylinder are connected. The output shaft of the mixing rod drives the conveying screw to rotate to inject the raw materials into the feeding valve. The slurry inside the feeding valve enters the feeding cylinder and enters the leak-proof feeding nozzle through the telescopic pipe and the second solenoid valve. The leak-proof feeding nozzle injects the slurry into the first mold and the second mold.

[0037] 3. The present invention can drive the coal gangue sound insulation board inside the forming mechanism to vibrate by setting a vibration mechanism. During the operation of the vibration mechanism, the electromagnetic brake fixes the rod body to prevent the shell from vibrating up and down. The vibration motor drives the vibration plate to vibrate slowly, and the spring elastically supports the bottom of the vibration plate. The vibration plate drives the vibration rod and the mounting seat to vibrate slowly synchronously. Through mechanical vibration, it is used to compact the slurry and discharge air bubbles, improve the density and strength of the board, and promote the slurry to enter the initial setting state faster.

[0038] 4. By setting the solidification mechanism, the present invention can further accelerate the solidification efficiency of the coal gangue sound insulation board. During the operation of the solidification mechanism, the output shaft of the stepping motor drives the screw rod to rotate, and the screw rod drives the nut sleeve and the air extraction hopper to move downward, aligning the power supply device with the controller. The piston rod of the fifth cylinder drives the power supply device to move, inserts the power supply plug into the power supply socket, the mains connector connects to the mains power supply and supplies power to the power supply device through the power cord, and the power supply device supplies power to the controller through the power supply plug and the power supply socket. The controller activates the temperature sensor and the heating wire, and the heating wire heats the first mold and the second mold to perform low-temperature and short-time heating on the coal gangue sound insulation board, and the temperature sensor detects the temperature of the coal gangue sound insulation board. After reaching the set temperature, the heating wire is turned off. By performing low-temperature and short-time heating, the solidification efficiency is accelerated, facilitating subsequent rapid demolding and shaping, and being suitable for large-scale production. After the heating is completed, the power supply device is reset and the motor is started. The output shaft of the motor drives the fan blade to rotate, extracting the outside cold air to the top of the inner cavity of the air extraction hopper. The cold air slowly cools the first mold and the second mold, and the air after absorbing heat is discharged through the top of the air extraction hopper. By performing slow air cooling, subsequent demolding is facilitated, preventing the coal gangue sound insulation board from being damaged due to sudden temperature drop when taken out from the mold interior.

[0085] Please refer to Figures 1 - 11, A method for using a forming and processing device for a coal gangue sound insulation board, comprising the following steps:

[0086] S1. The piston rod of the first cylinder 103 drives the lifting plate 104 to move upward. The lifting plate 104 drives the entire forming mechanism 400 on the right side to move upward, so that the anti-leakage feeding nozzle 223 penetrates through the seat body 401 and enters the inner cavity of the first mold 406. Then, the piston rod of the fourth cylinder 414 drives the rotating member 413 to rotate upward, and the rotating member 413 drives the clamping head 409 to rotate downward, so that the clamping head 409 presses against the anti-leakage feeding nozzle 223 to fix the anti-leakage feeding nozzle 223.

[0087] S2. Prepare the slurry for the coal gangue sound insulation board. Pour coal gangue particles, cement, reinforcing fibers, and auxiliary agents into the feeding hopper 207. The output shaft of the second reduction motor 206 drives the mixing rod 212 to rotate. The mixing rod 212 drives the dispersing frame 205 and the mixing frame 210 to rotate synchronously. The dispersing frame 205 breaks up the agglomerated raw materials, and the mixing frame 210 stirs and mixes the raw materials. During the stirring process, the external water source enters the annular pipe 209 through the first solenoid valve 217 and is evenly sprayed into the inner cavity of the mixing tank 204 through the one-way nozzle 208, so that the water and the raw materials are mixed into a slurry.

[0088] S3. After the slurry is mixed, the output shaft of the second cylinder 211 drives the sealing ring 216 away from the surface of the mixing rod 212, so that the mixing assembly 201 and the conveying cylinder 213 are connected. The output shaft of the mixing rod 212 drives the conveying screw 214 to rotate to inject the raw materials into the feeding valve 219. The slurry inside the feeding valve 219 enters the feeding cylinder 218 and enters the anti-leakage feeding nozzle 223 through the telescopic pipe 221 and the second solenoid valve 222. The anti-leakage feeding nozzle 223 injects the slurry into the first mold 406 and the second mold 405. The slurry forms in the inner cavities of the first mold 406 and the second mold 405. The annular piece 411 and the pressure sensor 410 detect the injection pressure of the slurry in the second mold 405. When the set pressure is reached, the second solenoid valve 222 is closed to stop the feeding, and the coal gangue sound insulation board is prepared.

[0089] S4. After the preparation is completed, reset the forming mechanism 400 on the right side. The rotating mechanism 100 drives the forming mechanism 400 to rotate, and grout is injected into the next forming mechanism 400. The forming mechanism 400 that has completed grouting rotates to the front side of the top of the rotating mechanism 100. The vibrating mechanism 300 drives the forming mechanism 400 on the front side to vibrate, accelerating the solidification of the gangue sound insulation board inside the forming mechanism 400. During the operation of the rotating mechanism 100, the output shaft of the first reduction motor 111 drives the small gear 110 to rotate. The small gear 110 drives the large gear 109 and the rotating rod 107 to rotate. The rotating rod 107 drives the turntable 106 to rotate. The turntable 106 drives a number of vibrating mechanisms 300 and forming mechanisms 400 to rotate synchronously. The angle sensor 112 detects the rotation angle of the rotating rod 107. When the set angle is reached, the first reduction motor 111 is turned off. During the rotation of the turntable 106, the support rod 105 and the universal wheel 102 are driven to slide on the top of the base 101 to prevent the turntable 106 from shaking during rotation;

[0090] S5. During the operation of the vibrating mechanism 300, the electromagnetic brake 108 fixes the rod body 306 to prevent the housing 301 from vibrating up and down. The vibrating motor 305 drives the vibrating plate 302 to vibrate slowly. The spring 304 elastically supports the bottom of the vibrating plate 302. The vibrating plate 302 drives the vibrating rod 303 and the mounting seat 407 to vibrate slowly synchronously. Through mechanical vibration, the slurry is compacted and air bubbles are discharged, improving the density and strength of the board and promoting the slurry to enter the initial setting state faster;

[0091] S6. After the vibration is completed, the rotating mechanism 100 continues to drive the forming mechanism 400 to rotate, and rotates the vibrated forming mechanism 400 to the bottom of the solidifying mechanism 500. At this time, the forming mechanism 400 on the right side completes the grouting. The grouted forming mechanism 400 continues to rotate to the front side of the top of the rotating mechanism 100 for vibration, realizing continuous and efficient processing. During the operation of the solidifying mechanism 500, the output shaft of the stepping motor 507 drives the lead screw 505 to rotate. The lead screw 505 drives the nut sleeve 506 and the air extraction hopper 501 to move downward, so that the power supply 510 is aligned with the controller 403. The piston rod of the fifth cylinder 513 drives the power supply 510 to move, inserts the power supply plug 509 into the power supply socket 404, the mains connector 511 connects to the mains and supplies power to the power supply 510 through the power cord 512. The power supply 510 supplies power to the controller 403 through the power supply plug 509 and the power supply socket 404. The controller 403 starts the temperature sensor 402 and the heating wire 412. The heating wire 412 heats the first mold 406 and the second mold 405 to perform low-temperature and short-time heating on the coal gangue sound insulation board. The temperature sensor 402 detects the temperature of the coal gangue sound insulation board. When the set temperature is reached, the heating wire 412 is turned off. Through low-temperature and short-time heating, the solidification efficiency is accelerated, which is convenient for subsequent rapid demolding and forming, and is suitable for large-scale production. After the heating is completed, the power supply 510 is reset and the motor 502 is started. The output shaft of the motor 502 drives the fan blade 503 to rotate, extracts the outside cold air to the top of the inner cavity of the air extraction hopper 501, and the cold air slowly cools the first mold 406 and the second mold 405. The heated air is discharged through the top of the air extraction hopper 501. Through slow air cooling, subsequent demolding is facilitated, and it is avoided that the coal gangue sound insulation board is damaged due to sudden temperature drop when taken out from the mold interior;

[0092] S7. After the cooling is completed, the solidifying mechanism 500 is reset. The rotating mechanism 100 continues to drive the forming mechanism 400 to rotate, and rotates the solidified coal gangue sound insulation board to the rear side of the top of the rotating mechanism 100. The staff disassembles the threaded rod 408, separates the first mold 406 and the second mold 405, then takes out the coal gangue sound insulation board inside the second mold 405, and puts the coal gangue sound insulation board into a high-temperature steam curing device for further curing.
