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 removes moisture or other liquids from the surface of objects through specific technical means. Drying equipment converts moisture in the material into steam and discharges it through heating, ventilation, evaporation, etc., thereby achieving the purpose of drying. It is widely used in many fields such as industry, agriculture, food processing, and medicine.

[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 according to a certain proportion. Then the mixed raw materials of bionic stone bricks are fed into the mold and the moisture contained in them is removed through a drying device. The drying equipment is usually also equipped with a compacting structure. The compacting structure 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 of synchronous drying and pressing can be carried out at one time, and the drying and shaping speed is fast.

[0004] Although the above-mentioned existing technology 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 attachments will cause irregular protrusions on the lower surface of the pressing plate. At the same time, the attachments will harden under the action of drying, which can easily cause irregular depressions on the surface of the imitation stone bricks produced, affecting the flatness of the imitation stone bricks. Frequent cleaning is required, which is not conducive to the continuous drying and pressing work. Summary of the Invention

[0005] The purpose of the present invention is to address the defects and shortcomings of the existing technology and provide a device for compacting and drying imitation stone brick raw materials using waste materials, which has high stone flatness and a long cleaning cycle.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a device for compacting and drying imitation stone brick raw materials using waste, comprising a base and an insulating bin fixedly arranged on the top surface of the base, the insulating bin being provided with openings on both sides, the outer wall of the insulating bin being movably engaged with an opening and closing door at the position of the opening, the top surface of the base being provided with a conveyor belt movably engaged with the base at both ends, the inner wall of the insulating bin being also provided with a processing table extending into the conveyor belt, the insulating bin being fixedly provided with a compacting structure at a corresponding position above the processing table, the inner wall of the insulating bin being penetrated by a plurality of hot air pipes, the compacting structure comprising a hydraulic press and a lower pressure column arranged on the bottom surface of the hydraulic press, the bottom surface of the lower pressure column being detachably mounted with a lower pressure plate, the side of the hydraulic press being also provided with a connecting frame, the end of the connecting frame being also provided with a pneumatic cleaning structure with a top end penetrating the top surface of the insulating bin, the pneumatic cleaning structure comprising a connecting frame The cam is secured to the bottom of the airbag and has an L-shaped upper end that is movably engaged with the bottom surface of the airbag and a middle rod that is movably engaged with the bottom surface of the airbag.

[0007] A further improvement is that a weight-reducing cavity is integrally formed in the base block, and a first rolling ball that can roll freely is provided on the inner wall of the weight-reducing cavity.

[0008] 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.

[0009] 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.

[0010] Further improvements are: 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, a gas nozzle that can be connected to an external gas source is penetrated by the upper plate, and a plurality of gas tubes connected to the gas cavity are penetrated by the bottom surface of the lower pressure block.

[0011] Further improvements are: the gas pipe includes a connecting pipe that penetrates the bottom surface of the lower pressure block and is connected to the gas cavity, and a limiting central axis integrally formed on the inner wall of the bottom of the connecting pipe, the bottom end of the limiting central axis is provided with a reset spring, the bottom end of the reset spring is connected to an upper blowing block whose top surface is in contact with the bottom surface of the limiting central axis and closes the bottom end of the connecting pipe, the upper blowing block includes a center block connected to the reset spring and a guide block arranged on the outer wall of the center block, the upper surface of the edge position of the guide block is integrally formed with a guide slope protruding upward, and the upper surface of the guide block is located on the lower side of the guide slope and is integrally formed with a guide groove.

[0012] To achieve the above-mentioned 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:

[0013] 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. After mixing, pour the mixture into the mold, and place the mold with the mixture on the conveyor belt of the compaction and drying device. Send the mold into the insulation bin through the conveyor belt, stop the conveyor belt, place the mold between the processing table and the compaction structure, and connect the external air source and 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 squeeze the lower pressure plate into 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 warehouse. 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:

[0018] When the present invention is in use, the high-pressure air source is connected to the pneumatic cleaning structure of the compacting structure during use. After the compaction is completed, when the lower pressure 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, thereby causing the first air pressure plate to descend, thereby pushing the second air pressure plate, and causing the cleaning block to protrude outward. Since the lower pressure 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 into the lower surface of the lower pressure plate, thereby scraping off and cleaning the attached layer on the lower surface of the lower pressure plate during the protruding process, thereby keeping the flatness of the lower surface of the lower pressure plate at a high level, preventing the protrusion of the attached objects from affecting the flatness of the compacted imitation stone bricks.

[0019] During the cleaning process performed by the pneumatic cleaning structure of the present invention, the rolling wheel can also be fitted with the bottom surface of the lower pressure plate, so that the outer ring of the rolling wheel rotates synchronously during the cleaning process, thereby causing the impact ball at the top of the elastic member to be periodically stuck into the slot block, thereby impacting the deformed plate, and then causing the deformed plate to bulge and cause the second rolling ball to roll in the impact cavity to produce intensive vibrations, thereby causing the base block and the shovel head to loosen the attachments through vibration when removing the attachments, making it easier to remove, and at the same time preventing the attachments after removal from adhering to the shovel head, affecting the subsequent cleaning effect.

[0020] When the present invention is working, the air source can be connected to the air nozzle. When the lower pressure plate is pressed down, the limiting central axis at the bottom of the gas tube cooperates with the upper blowing block to keep the bottom surface of the lower pressure block flat, thereby not affecting the surface flatness of the imitation stone brick during the compaction process. After the compaction is completed, the air can be introduced into the gas cavity through the air nozzle, thereby making the air flow downward along the connecting pipe and causing the upper blowing block to move downward. At this time, if there is an adhesion layer attached to the lower surface of the lower pressure plate, the adhesion layer can be impacted by moving the upper blowing block downward to crack the adhesion layer, and after the upper blowing block moves down to a certain extent, the gas can flow outward and, under the guiding action of the upper blowing block, impact and blow on the bottom surface of the lower pressure plate, so that the adhesion layer is further loosened or even blown off, thereby making the adhesion less after each use, further extending the cleaning cycle and preventing the protrusion of the adhesion from affecting the flatness of the compacted imitation stone brick.

The upper blow block 54 includes a central block 541 connected to the return spring 53 and a guide block 542 arranged on the outer wall of the central block 541. The upper surface of the edge of the guide block 542 is integrally formed with an upwardly protruding guide slope 543. The upper surface of the guide block 542 is located on the low side of the guide slope 543 and is integrally formed with a guide groove 544. A connecting frame 64 is also provided on the side of the hydraulic press 61. The end of the connecting frame 64 is also provided with a pneumatic cleaning structure whose top penetrates the top surface of the heat insulation bin 4. The pneumatic cleaning structure includes an L-shaped air pipe 65 connected to the end of the connecting frame 64 and an inflation head 66 arranged at the top of the air pipe 65. The upper surface of the bottom end of the air pipe 65 is flush with the bottom surface of the lower pressure plate 63 after it rises to the top, and the top of the inner wall of the air pipe 65 is fitted and slidably provided with a first The air pressure piece 67 and the bottom of the air pipe 65 are fitted and slidably provided with a second air pressure piece 68, and a cleaning block 69 is detachably provided on the second air pressure piece 68. The cleaning block 69 includes a card block 33 detachably connected to the second air pressure piece 68 and a base block 31 arranged on one side of the card block 33. A shovel head 32 with a triangular cross-section is provided on one side of the base block 31. The top surface of the base block 31 is also movably engaged with a rolling wheel 36 that can be fitted with the bottom surface of the lower pressure plate 63. The rolling wheel 36 includes an outer ring 361 that can be fitted with the bottom surface of the lower pressure plate 63 and a middle rod 362 movably engaged with the outer ring 361 and connected to the base block 31. The outer wall of the middle rod 362 is provided with a plurality of elastic members 363 composed of two elastic sheets, and the top of the elastic member 363 is provided with an impact ball 364 that fits with the inner wall of the outer ring 361.The inner wall of the outer ring 361 is also provided with a plurality of snap-in groove blocks 365, which include a fixed groove 43 provided on the inner wall of the outer ring 361 and a deformation plate 41 fixedly provided at both ends of the fixed groove 43. An impact cavity 44 is formed between the deformation plate 41 and the fixed groove 43, and a second rolling ball 45 is provided in the impact cavity 44 so as to roll freely. A guide plate 42 is provided on both sides of the fixed groove 43. 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 compacting structure 6, so that the gas can be injected into the air pipe 65 from the inflation head 66, and the oil pressure pipe is connected to the hydraulic press 61. Then, the mixed raw materials are placed in 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 the raw material to form an imitation stone brick. 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 scraping off and cleaning the attached layer on the lower surface of the lower pressing plate 63 during the protrusion process, thereby keeping 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 attached objects.

[0032] At the same time, during the cleaning process 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, thereby causing the impact ball 364 at the top of the elastic member 363 to be periodically engaged with the engaging groove block 365, and at the moment of engaging, it hits the deformed plate 41 of the engaging groove block 365, thereby causing the deformed plate 41 to produce a convex deformation, causing the top of the deformed plate 41 to cross the impact cavity 44 and collide with the fixed groove 43, generating a vibration. At the same time, the deformed plate 41 is convex, causing the second rolling ball 45 to roll in the impact cavity 44, and repeatedly collide with the fixed groove 43 to generate intensive vibration, thereby causing the base block 31 and the shovel head 32 to loosen the attached objects through vibration when they are removing the attached objects, thereby making it easier to remove the attached objects on the bottom surface of the lower pressure plate 63, and at the same time preventing the removed attached objects 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.

[0033] 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 tube 635 at 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 upward, 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 there is an adhesion layer attached to the lower surface of the lower pressure plate 63, the bottom surface of the upper blowing block 54 can be impacted by moving the upper blowing block 54 downward. The upper blow block 54 is moved down to a certain extent, so that the gas can flow out from the bottom of the connecting pipe 51, and under the guidance of the upwardly tilted guide slope 543 and the guide groove 544 of the guide block 542 of the upper blow block 54, the high-pressure gas is blown on the bottom surface of the lower pressing block 632 of the lower pressing plate 63, so that the attachment layer is further loosened or even blown off, thereby making the attachment less after each use. Then, the gas input by the air nozzle 633 is withdrawn, and the reset spring 53 can pull back the upper blow block 54 to restore it, thereby keeping the bottom surface of the lower pressing block 632 flat, further extending the cleaning cycle and preventing the protrusion of the attachment from affecting the flatness of the compacted imitation stone brick.

[0034] A weight-reducing cavity 34 is integrally formed in the base block 31. A freely rolling first ball 35 is provided on the inner wall of the weight-reducing cavity 34, which helps to reduce the weight of the base block 31 and makes it easier to push. At the same time, during movement, the first ball 35 can be rolled in the weight-reducing cavity 34 by inertia, thereby generating additional vibration, further preventing the removed attachments 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.

[0035] The outer wall of the outer ring 361 is also integrally formed with a roughened friction layer 366. The outer wall of the friction layer 366 is also integrally formed with a plurality of friction bumps 367. This helps to generate higher friction when the outer ring 361 moves in contact with the bottom surface of the lower pressure plate 63, preventing slippage, thereby enabling faster rotation and generating more vibration.

[0036] The present invention also provides a method for drying raw materials for imitation stone bricks, which is applied to a device for compacting and drying raw materials for imitation stone bricks using waste materials, and comprises the following steps:

[0037] Step 1: Connect high-temperature air flow to the hot air pipe 5 to send hot air into the insulation chamber 4 for preheating for 20 minutes to 30 minutes.

[0038] 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 place the mold with the mixture on the conveyor belt 2 of the compaction and drying device. Send the mold into the insulation bin 4 through the conveyor belt 2, stop the conveyor belt 2, place the mold 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.

[0039] Step 3: Start the compacting 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 maintained for 10min-15min.

[0040] Step 4: Turn off the hydraulic press 61, reset the lower pressure plate 63, and start the conveyor belt 2 to send the dried and formed plates together with the mold out of the insulation warehouse 4. After sending them out, manually knock on the plates with an iron stick to confirm the hardness and dryness of the plates.

[0041] 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 heat-insulating bin 4, 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 conjunction 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 piece 67 to descend, thereby pushing the second air pressure piece 68 through the gas between the first air pressure piece 67 and the second air pressure piece 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 into the lower surface of the lower pressing plate 63, thereby scraping off and cleaning the attached layer on the lower surface of the lower pressing plate 63 during the protruding process, thereby keeping 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 attached objects;

[0042] At the same time, during the cleaning process 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, thereby causing the impact ball 364 at the top of the elastic member 363 to be periodically engaged with the engaging groove block 365, and at the moment of engaging, it hits the deformed plate 41 of the engaging groove block 365, thereby causing the deformed plate 41 to produce a convex deformation, causing the top of the deformed plate 41 to cross the impact cavity 44 and collide with the fixed groove 43, generating a vibration. At the same time, the deformed plate 41 is convex, causing the second rolling ball 45 to roll in the impact cavity 44, and repeatedly collide with the fixed groove 43 to generate intensive vibration, thereby causing the base block 31 and the shovel head 32 to loosen the attached objects through vibration when they are removing the attached objects, thereby making it easier to remove the attached objects on the bottom surface of the lower pressure plate 63, and at the same time preventing the removed attached objects 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.

[0043] 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 tube 635 at 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 upward, 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 there is an adhesion layer attached to the lower surface of the lower pressure plate 63, the bottom surface of the upper blowing block 54 can be impacted by moving the upper blowing block 54 downward. The upper blow block 54 is moved down to a certain extent, so that the gas can flow out from the bottom of the connecting pipe 51, and under the guidance of the upwardly tilted guide slope 543 and the guide groove 544 of the guide block 542 of the upper blow block 54, the high-pressure gas is blown on the bottom surface of the lower pressing block 632 of the lower pressing plate 63, so that the attachment layer is further loosened or even blown off, thereby making the attachment less after each use. Then, the gas input by the air nozzle 633 is withdrawn, and the reset spring 53 can pull back the upper blow block 54 to restore it, thereby keeping the bottom surface of the lower pressing block 632 flat, further extending the cleaning cycle and preventing the protrusion of the attachment from affecting the flatness of the compacted imitation stone brick.
