Description

Technical Field

[0001] The invention relates to the technical field of grouting molding, and in particular to a molding and processing device for a coal gangue sound insulation board and a preparation method thereof. Background Art

[0002] The gangue sound insulation board forming and processing device is an industrial equipment specially used to convert gangue into sound insulation board. Gangue is a by-product produced in the process of coal mining, usually containing a certain proportion of inorganic minerals. The raw materials of gangue sound insulation board include gangue particles, cement, reinforcing fiber and auxiliary agents. These materials are evenly mixed with water to form the raw material slurry of gangue sound insulation board.

[0003] The coal gangue sound insulation board can ensure a more uniform distribution of the mixture in the mold through grouting. 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, and grouting can help improve the density of the board.

[0004] The fully automatic high-pressure grouting molding production line with Chinese patent application number 200420115826.4. It uses an oil pressure system to achieve mold locking and mold opening. The pressure mud is pressed into the mold cavity through the mud pressure system, and the slurry intake process is completed by relying on the filtering and water absorption capacity of the mold. For products that need to be drained, the model can be installed on a tiltable stand to tilt the slurry. It uses a vacuum system to accelerate the speed of slurry intake or adsorb the product on a certain mold so that the product can move at the same time as the mold when demolding. Through the compressed air system, the water absorbed by the mold from the mud is blown back between the product and the mold to achieve the purpose of separating the product and 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 low, and it takes a longer time to complete the solidification process, which leads to an extension of the production cycle and affects the production efficiency and capacity. Summary of the invention

Mechanical vibration is used to compact the slurry and discharge bubbles, thereby improving the density and strength of the plate and prompting the slurry to enter the initial setting state faster.

[0038] 4. The present invention can further accelerate the solidification efficiency of the gangue sound insulation board by setting a solidification mechanism. During the operation of the solidification mechanism, the output shaft of the stepper motor drives the screw to rotate, and the screw drives the nut sleeve and the exhaust bucket to move downward, so that the power supply is aligned with the controller. The piston rod of the fifth cylinder drives the power supply to move, and the power supply plug is inserted into the power supply socket. The mains connector is connected to the mains and supplies power to the power supply through the power cord. The power supply supplies power to the controller through the power supply plug and the power supply socket. The controller starts the temperature sensor and the heating wire, and the heating wire heats the first mold and the second mold to perform low temperature solidification on the gangue sound insulation board. After a short period of heating, the temperature sensor detects the temperature of the gangue sound insulation board. When the set temperature is reached, the heating wire is turned off. Through low-temperature short-term heating, the solidification efficiency is accelerated, which is convenient for subsequent rapid demoulding and molding. It is suitable for large-scale production. After the heating is completed, the power supply is reset and the motor is started. The output shaft of the motor drives the fan blades to rotate, and the cold air from the outside is drawn to the top of the inner cavity of the exhaust hopper. The cold air slowly cools down the first mold and the second mold. The air after absorbing heat is discharged through the top of the exhaust hopper. Through slow air cooling, it is convenient for subsequent demoulding, and avoids the gangue sound insulation board from being damaged by sudden cooling when it is taken out from the inside of the mold.

The breaking rack 205 breaks up the agglomerated raw materials. The mixing rack 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 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 is connected to the conveying cylinder 213.

After the preparation is completed, the molding mechanism 400 on the right is reset, and the rotating mechanism 100 drives the molding mechanism 400 to rotate, and grouting is performed on the next molding mechanism 400.

The temperature sensor 402 detects the temperature of the gangue sound insulation board, and turns off the heating wire 412 when the set temperature is reached. The low-temperature short-time heating is used to accelerate the solidification efficiency, which is convenient for subsequent rapid demoulding and molding, 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, and the cold air from the outside is drawn to the top of the inner cavity of the exhaust hopper 501. The cold air slowly cools the first mold 406 and the second mold 405. The air after absorbing heat is discharged through the top of the exhaust hopper 501. The slow air cooling is convenient for subsequent demoulding, and the gangue sound insulation board is prevented from being damaged due to sudden cooling when it is taken out from the inside of the mold.
