Description

Technical Field

[0001] The invention relates to the technical field of drying, and in particular to a device for compacting and drying imitation stone brick raw materials using waste materials and a drying method thereof. Background Art

[0002] Drying equipment is a combination of mechanical equipment that uses specific technical means to remove moisture or other liquids from the surface of objects. Drying equipment converts moisture in materials into steam and discharges it through heating, ventilation, evaporation, etc., thereby achieving the purpose of drying. It is widely used in industry, agriculture, food processing, medicine and other fields.

[0003] In the field of imitation stone brick production, the main raw materials of bionic stone bricks include natural stone powder, high-grade cement, admixtures, brighteners or waterproof inorganic materials, etc. Tile waste or stone waste can also be recycled as raw materials for secondary processing. After the raw materials are mixed and crushed, they are vibrated and formed in a certain proportion. The mixed raw materials of bionic stone bricks are then fed into the mold and the moisture contained in them is removed through a drying device. The drying equipment usually also has a compaction structure, which cooperates with the mold to dry, harden and shape the bionic stone brick raw materials fed in, so that the size and flatness of the produced imitation stone bricks are more uniform, and large quantities can be dried and pressed synchronously at one time, and the drying and shaping speed is fast.‌ Although the above-mentioned prior art can solve the corresponding technical problems, it still has certain defects: when the existing compaction and drying device presses and dries the imitation stone brick raw materials processed from recycled gravel waste, if the recycled gravel waste contains a large amount of silicate mud components, then after stirring and mixing, the mixed raw materials will have a higher viscosity, and then during the drying and pressing process, it is easy to cause part of the mixed raw materials to adhere to the pressing plate of the pressing device. After a period of use, the attached materials will cause irregular protrusions on the lower surface of the pressing plate. At the same time, the attached materials will harden under the drying action, which can easily cause irregular depressions on the surface of the produced imitation stone bricks, affecting the flatness of the imitation stone bricks, requiring frequent cleaning, which is not conducive to the continuous drying and pressing work.

[0009] A further improvement is that: the outer wall of the outer ring is also integrally formed with a roughened friction layer, and the outer wall of the friction layer is also integrally formed with a plurality of friction protrusions.

[0010] A further improvement is that the snap-in slot block includes a fixed slot arranged on the inner wall of the outer ring and a deformation plate fixedly arranged at both ends of the fixed slot, an impact cavity is formed between the deformation plate and the fixed slot, a second rolling ball is freely rolling in the impact cavity, and guide plates are provided on both sides of the fixed slot.

[0011] Further improvement is: the lower pressure plate includes an upper plate detachably connected to the bottom end of the lower pressure column and a lower pressure block arranged on the bottom surface of the upper plate, a gas cavity is formed between the top surface of the lower pressure block and the bottom surface of the upper plate, the upper plate is penetrated with a gas nozzle that can be connected to an external gas source, and the bottom surface of the lower pressure block is penetrated with a plurality of gas pipes connected to the gas cavity.

[0013] To achieve the above purpose, the present invention can also adopt the following technical solution: a method for drying imitation stone brick raw materials, applied to a device for compacting and drying imitation stone brick raw materials using waste materials, comprising the following steps: Step 1: Connect high-temperature air flow to the hot air pipe to send hot air into the insulation chamber for preheating for 20 minutes to 30 minutes.

[0014] Step 2: After crushing the stone waste, add high-grade cement, admixtures, brightener, and water, mix the mixture and pour it into the mold, and put the mold with the mixture on the conveyor belt of the compaction and drying device, and send the mold into the insulation bin through the conveyor belt, stop the conveyor belt, so that the mold is between the processing table and the compaction structure, and connect the external air source and the external hydraulic oil to the compaction structure.

[0015] Step 3: Start the compaction structure, press down the lower pressure column through the hydraulic press to make the lower pressure plate squeeze the upper surface of the mold, control the pressure at 80Mpa-85Mpa, and maintain the pressure for 10min-15min.

[0016] Step 4: Turn off the hydraulic press, reset the lower pressure plate, and start the conveyor belt to send the dried and formed plates together with the mold out of the insulation bin. After sending them out, manually knock on the plates with an iron stick to confirm the hardness and dryness of the plates.

[0017] After adopting the above technical solution, the beneficial effects of the present invention are: When the present invention is in use, during the use process, a high-pressure air source is connected to the pneumatic cleaning structure of the compaction structure. After the compaction is completed, when the lower pressing plate is lifted to the top, the gas can be introduced from the inflation head into the air pipe through the high-pressure air source, and then the first air pressure plate descends, thereby pushing the second air pressure plate, and further causing the cleaning block to protrude outwards. Since the lower pressing plate is flush with the upper surface of the bottom end of the air pipe, the shovel head of the cleaning block can just fit the lower surface of the lower pressing plate, thereby removing and cleaning the attachment layer on the lower surface of the lower pressing plate during the protruding process, and further keeping the flatness of the lower surface of the lower pressing plate at a relatively high level, preventing the flatness of the imitation stone brick after compaction from being affected due to the protrusion of the attachment.

[0018] During the cleaning process of the present invention through the pneumatic cleaning structure, the rolling wheel can also be attached to the bottom surface of the lower pressing plate, so that the outer ring of the rolling wheel rotates synchronously during the cleaning process, and then the impact ball at the top of the elastic member is periodically stuck into the clamping groove block to impact the deformation plate, and then the deformation plate bulges to make the second rolling ball roll in the impact cavity to generate intensive vibration. Then, when the base block and the shovel head remove the attachments, the attachments are loosened through vibration, making it easier to remove, and at the same time, preventing the attachments after removal from adhering to the shovel head and affecting the subsequent cleaning effect.

[0019] When the present invention works, the air source can be connected to the air nozzle. When the lower pressing plate is pressed down, the bottom surface of the pressing block is kept flat through the limiting central axis at the bottom of the gas pipe and the upper blowing block, and thus the surface flatness of the imitation stone brick during the compaction process will not be affected. After the compaction is completed, the gas can be introduced into the gas cavity through the air nozzle, so that the gas flows downward along the connecting pipe and the upper blowing block moves downward. At this time, if there is an attachment layer on the lower surface of the lower pressing plate, the attachment layer can be impacted by the downward movement of the upper blowing block to make the attachment layer crack. After the upper blowing block moves downward to a certain extent, the gas can flow outwards and impact and blow on the bottom surface of the lower pressing plate under the guiding action of the upper blowing block, so that the attachment layer is further loosened or even blown off. Thus, after each use, there will be less attachment, further prolonging the cleaning cycle and preventing the flatness of the imitation stone brick after compaction from being affected due to the protrusion of the attachment.

An impact cavity 44 is formed between the deformation plate 41 and the fixed slot 43. A second rolling ball 45 is freely rolling in the impact cavity 44. Both sides of the fixed slot 43 are provided with a guide plate 42. When in use, the hot air flow is sent from the hot air pipe 5 into the heat insulation bin 4, and the high-pressure air source is connected to the inflation head 66 of the pneumatic cleaning structure of the compaction structure 6, so that the gas can be poured into the air pipe 65 from the inflation head 66, and the oil pressure pipe is connected to the hydraulic press 61, and then the mixed raw materials are put into the mold, and the mold is moved to the position of the processing table 3 by the conveyor belt 2. At this time, the hot air output by the hot air pipe 5 can be used to dry the raw materials in the mold, and the hydraulic press 61 presses down the lower pressure column 62 to press the lower pressure column 62. The pressing plate 63 is pressed downward, thereby squeezing the raw material in the mold through the bottom surface of the lower pressing block 632 of the lower pressing plate 63 to compact the raw material in the mold, and drying is used to shape the raw material into imitation stone bricks. After the compaction is completed, when the lower pressing plate 63 is lifted to the top, the gas can be introduced from the inflation head 66 into the air pipe 65 through the high-pressure gas source, thereby causing the first air pressure sheet 67 to descend, thereby pushing the second air pressure sheet 68 through the gas between the first air pressure sheet 67 and the second air pressure sheet 68, thereby causing the cleaning block 69 to protrude outward. Since the lower pressing plate 63 is flush with the upper surface of the bottom end of the air pipe 65, the shovel head 32 of the cleaning block 69 can just fit the lower surface of the lower pressing plate 63, thereby removing and cleaning the attached layer on the lower surface of the lower pressing plate 63 during the protruding process, thereby maintaining the flatness of the lower surface of the lower pressing plate 63 at a high level, preventing the flatness of the imitation stone brick after subsequent compaction from being affected by the protrusion of the attached objects; At the same time, in the process of cleaning by the pneumatic cleaning structure, the rolling wheel 36 can also be fitted with the bottom surface of the lower pressure plate 63, so that the outer ring 361 of the rolling wheel 36 rotates synchronously during the cleaning process, so that the impact ball 364 at the top of the elastic member 363 is periodically inserted into the inserted groove block 365, and at the moment of inserting, it hits the deformed plate 41 of the inserted groove block 365, so that the deformed plate 41 is deformed to convexly deform, so that the top of the deformed plate 41 crosses the impact cavity 44 and collides with the fixed groove 43 to generate a vibration, and at the same time, the deformed plate 41 is convex to make the second rolling ball 45 roll in the impact cavity 44, and repeatedly collide with the fixed groove 43 to generate intensive vibration, so that the base block 31 and the shovel head 32 are loosened by vibration when removing the attached objects, so that the attached objects on the bottom surface of the lower pressure plate 63 are easier to remove, and at the same time, the removed attached objects are prevented from adhering to the shovel head 32 and affecting the subsequent cleaning effect, so that a good cleaning effect can be maintained after multiple cleanings; At the same time, the high-pressure gas source can be connected to the gas nozzle 633. When the lower pressure plate 63 is pressed down, the limiting center axis 52 at the bottom of the connecting pipe 51 of the gas pipe 635 on the bottom of the lower pressure block 632 presses against the upper blowing block 54, so that the upper blowing block 54 will not continue to move up, so that the bottom surface of the lower pressure block 632 remains flat, and thus will not affect the surface flatness of the imitation stone bricks during the compaction process. After the compaction is completed, the gas can be introduced into the gas cavity 634 through the gas nozzle 633, so that the gas flows downward along the connecting pipe 51 and moves the upper blowing block 54 downward. At this time, if the lower surface of the lower pressure plate 63 is attached with an adhesion layer, the bottom surface of the upper blowing block 54 can be impacted by moving the upper blowing block 54 downward. The adhesion layer is hit to crack the adhesion layer, and after the upper blowing block 54 moves down to a certain extent, the gas can flow out from the bottom of the connecting pipe 51, and under the guiding action of the upwardly tilted guide slope 543 and the guide groove 544 of the guide block 542 of the upper blowing block 54, the high-pressure gas is impacted and blown on the bottom surface of the lower pressing block 632 of the lower pressing plate 63, so that the adhesion layer is further loosened or even blown off, so that the adhesion can be reduced after each use, and then the gas input by the air nozzle 633 is withdrawn, the reset spring 53 can pull back the upper blowing block 54 to restore it, keep the bottom surface of the lower pressing block 632 flat, further extend the cleaning cycle and prevent the flatness of the imitation stone brick after compaction from being affected by the protrusion of the adhesion.

[0024] A weight-reducing cavity 34 is integrally formed in the base block 31. A first rolling ball 35 that can roll freely is provided on the inner wall of the weight-reducing cavity 34, which is conducive to reducing the weight of the base block 31, thereby making it easier to push. At the same time, when moving, the first rolling ball 35 can roll in the weight-reducing cavity 34 by inertia, thereby generating additional vibration, further preventing the attachments after shoveling from adhering to the shovel head 32 and affecting the subsequent cleaning effect, so that a good cleaning effect can be maintained after multiple cleanings; The outer wall of the outer ring 361 is also integrally formed with a roughened friction layer 366, and the outer wall of the friction layer 366 is also integrally formed with a plurality of friction protrusions 367, which are conducive to generating a higher friction force when the outer ring 361 moves in contact with the bottom surface of the lower pressing plate 63, and is not easy to slip, thereby making it rotate faster and generating more vibration; The present invention also provides a method for drying imitation stone brick raw materials, which is applied to a device for compacting and drying imitation stone brick raw materials using waste materials, and comprises the following steps: Step 1: Connect an external high-temperature air flow to the hot air pipe 5 so that it delivers the hot air into the insulation bin 4 for preheating for 20 minutes to 30 minutes.

[0025] Step 2: After crushing the stone waste, add high-grade cement, admixtures, brightener and water, mix the mixture and pour it into the mold, and put the mold with the mixture onto the conveyor belt 2 of the compaction and drying device, and send the mold into the insulation bin 4 through the conveyor belt 2, stop the conveyor belt 2, so that the mold is between the processing table 3 and the compaction structure 6, and connect the external air source and the external hydraulic oil to the compaction structure 6.

[0026] Step 3: Start the compaction structure 6, and use the hydraulic press 61 to press down the lower pressing column 62 to make the lower pressing plate 63 squeeze the upper surface of the mold. The pressure is controlled at 80Mpa-85Mpa, and the pressure is maintained for 10min-15min.

[0027] Step 4: turn off the hydraulic press 61, reset the lower pressing plate 63, and start the conveyor belt 2 to send the dried and formed board together with the mold out of the insulation bin 4. After sending out, manually knock the board with an iron stick to confirm the hardness and dryness of the board.

[0028] Working principle of the present invention: When the present invention is used, the hot air flow is sent from the hot air pipe 5 into the insulation bin 4 during use, and the high-pressure air source is connected to the inflation head 66 of the pneumatic cleaning structure of the compacting structure 6, so that the gas can be poured into the air pipe 65 from the inflation head 66, and the oil pressure pipe is connected to the hydraulic press 61, and then the mixed raw materials are put into the mold, and the mold is moved to the position of the processing table 3 through the conveyor belt 2. At this time, the hot air output by the hot air pipe 5 can be used to dry the raw materials in the mold, and the hydraulic press 61 presses down the lower pressure column 62 to squeeze the lower pressure plate 63 downward, thereby squeezing the raw materials in the mold through the bottom surface of the lower pressure block 632 of the lower pressure plate 63 to compact the raw materials in the mold, and the raw materials are formed in combination with drying. To make imitation stone bricks, after the compaction is completed, when the lower pressing plate 63 is lifted to the top, the gas can be introduced from the inflation head 66 into the air pipe 65 through the high-pressure gas source, thereby causing the first air pressure plate 67 to descend, thereby pushing the second air pressure plate 68 through the gas between the first air pressure plate 67 and the second air pressure plate 68, thereby causing the cleaning block 69 to protrude outward. Since the lower pressing plate 63 is flush with the upper surface of the bottom end of the air pipe 65, the shovel head 32 of the cleaning block 69 can just fit the lower surface of the lower pressing plate 63, thereby removing and cleaning the attached layer on the lower surface of the lower pressing plate 63 during the protruding process, thereby maintaining the flatness of the lower surface of the lower pressing plate 63 at a high level, preventing the flatness of the imitation stone bricks after subsequent compaction from being affected by the protrusion of the attached objects; At the same time, in the process of cleaning by the pneumatic cleaning structure, the rolling wheel 36 can also be fitted with the bottom surface of the lower pressure plate 63, so that the outer ring 361 of the rolling wheel 36 rotates synchronously during the cleaning process, so that the impact ball 364 at the top of the elastic member 363 is periodically inserted into the inserted groove block 365, and at the moment of inserting, it hits the deformed plate 41 of the inserted groove block 365, so that the deformed plate 41 is deformed to convexly deform, so that the top of the deformed plate 41 crosses the impact cavity 44 and collides with the fixed groove 43 to generate a vibration, and at the same time, the deformed plate 41 is convex to make the second rolling ball 45 roll in the impact cavity 44, and repeatedly collide with the fixed groove 43 to generate intensive vibration, so that the base block 31 and the shovel head 32 are loosened by vibration when removing the attached objects, so that the attached objects on the bottom surface of the lower pressure plate 63 are easier to remove, and at the same time, the removed attached objects are prevented from adhering to the shovel head 32 and affecting the subsequent cleaning effect, so that a good cleaning effect can be maintained after multiple cleanings; At the same time, the high-pressure gas source can be connected to the gas nozzle 633. When the lower pressure plate 63 is pressed down, the limiting center axis 52 at the bottom of the connecting pipe 51 of the gas pipe 635 on the bottom of the lower pressure block 632 presses against the upper blowing block 54, so that the upper blowing block 54 will not continue to move up, so that the bottom surface of the lower pressure block 632 remains flat, and thus will not affect the surface flatness of the imitation stone bricks during the compaction process. After the compaction is completed, the gas can be introduced into the gas cavity 634 through the gas nozzle 633, so that the gas flows downward along the connecting pipe 51 and moves the upper blowing block 54 downward. At this time, if the lower surface of the lower pressure plate 63 is attached with an adhesion layer, the bottom surface of the upper blowing block 54 can be impacted by moving the upper blowing block 54 downward. The adhesion layer is hit to crack the adhesion layer, and after the upper blowing block 54 moves down to a certain extent, the gas can flow out from the bottom of the connecting pipe 51, and under the guiding action of the upwardly tilted guide slope 543 and the guide groove 544 of the guide block 542 of the upper blowing block 54, the high-pressure gas is impacted and blown on the bottom surface of the lower pressing block 632 of the lower pressing plate 63, so that the adhesion layer is further loosened or even blown off, so that the adhesion can be reduced after each use, and then the gas input by the air nozzle 633 is withdrawn, the reset spring 53 can pull back the upper blowing block 54 to restore it, keep the bottom surface of the lower pressing block 632 flat, further extend the cleaning cycle and prevent the flatness of the imitation stone brick after compaction from being affected by the protrusion of the adhesion.
