Description

Technical Field

[0001] The present invention relates to the technical field of porous brick production, and in particular to a sintered porous brick forming mechanism and a forming method. Background Art

[0002] Sintered porous bricks are made of clay, shale, coal gangue, fly ash, silt and other solid waste as the main raw materials, and are made by roasting. They are mainly used in the load-bearing parts of buildings. Sintered porous bricks are a kind of building bricks produced by baking. Sintering is a production method in which red bricks are placed in a high-temperature kiln for firing and can be formed after cooling. Porous bricks are just the shape of traditional bricks with more holes distributed, which not only increases the thermal insulation effect but also improves the strength. Therefore, sintered porous bricks have been widely used in the construction industry.

[0003] In the production process of porous bricks, the raw materials need to be extruded and shaped, and then the shaped strip blanks need to be cut. Finally, the cut porous brick blanks can be fired in a kiln to become porous bricks. The existing extrusion molding and cutting of the blanks have been fully automated and streamlined. However, although the existing production line can achieve high-efficiency production, its shortcomings are more obvious. For example, in the cutting process, after the cutting is completed, the surface of the cutting blade will be stained with the residue of the blank, which will affect the cutting effect of the blank in the next cutting. Moreover, after the cutting is completed, the edge of the strip blank cannot meet the specified size, commonly known as scraps, which are currently discharged directly outward as the conveyor rack moves, resulting in waste of raw materials.

[0024] The beneficial effects of the present invention are:

[0025] 1. By setting a cleaning component, the sealing plate moves up and down inside the sealing box, and the space below the sealing plate is injected and compressed. When the sealing plate moves downward, the water injected below the sealing plate can be sprayed toward the slitting blade through the nozzle to clean the raw materials adhered to the outer surface of the slitting blade. When the sealing plate moves upward, the water inside the water storage tank can be injected into the bottom of the sealing plate through the water pipe, the first diversion pipe, the first connecting pipe, the second connecting pipe and the water inlet pipe to complete the water injection operation of the space below the sealing plate. This reciprocating process can achieve the purpose of cleaning the slitting blade after slitting, thereby avoiding the problem that the outer surface of the existing slitting blade adheres to the raw materials after slitting and affects the cutting of the blank.

[0026] 2. By setting up a crushing assembly and a reflux assembly, the output shaft of the cylinder drives the connecting rod to move upward, that is, drives the sealing plate to move upward inside the sealing box, which will compress the air on the top surface of the sealing plate into the inside of the air guide pipe, and then transported by the air guide pipe to the inside of the second diversion pipe, and then transported by the second diversion pipe to the inside of the air delivery pipe on its bottom, and finally blown out to the paddle plate through the blowing nozzle, thereby driving the rotating shaft to rotate. When the rotating shaft rotates, it drives the fixed sleeve and the slapping plate to rotate, thereby slapping the fallen scraps, making them fall into the collection box in a loose state, thereby realizing the slapping operation of the scraps. When the scraps stored in the collection box reach a certain amount, the suction pump can be started to suck the scraps stored in the collection box into the inside of the delivery pipe, and then re-enter the inside of the feed pipe through the feed pipe, forming a cycle, which can effectively avoid waste of raw materials.

When the sealing plate 24 moves downward inside the sealing box 13, the water injected below the sealing plate 24 can be pressed into the inside of the clamping rack 28. At this time, the first one-way solenoid valve on the outer surface of the water inlet pipe 21 is in a closed state, and the second solenoid valve 31 is in an open state. Finally, water is sprayed to the outer surface of the slitting blade 26 through the bend 29 and the nozzle 30 to clean the raw materials adhered to the outer surface of the slitting blade 26. As the sealing plate 24 continues to move downward, when the sealing plate 24 contacts the water inlet rack 25, it cannot move. As the connecting rod 23 continues to apply pressure under the push of the cylinder 12, the slitting box 14 can be continuously pushed to the blank on the top surface of the third conveyor rack 3.The blank is cut into a plurality of blocks of the same size by the slitting blade 26. After the slitting is completed, the cylinder 12 cancels the pressure, and the slitting box 14 and the sealing box 13 are moved away from the top of the third conveyor rack 3 under the action of the spring under the movable sleeve block 15. At this time, the sealing plate 24 is still in close contact with the top surface of the water inlet rack 25.

When the scraps fall downward, during the upward movement of the sealing plate 24, the air on the top surface of the sealing plate 24 will be compressed into the interior of the air guide pipe 22, and then transported by the air guide pipe 22 to the interior of the second diverter pipe 37, and then transported by the second diverter pipe 37 to the interior of the air delivery pipe 44 on its bottom, and finally blown out to the paddle plates 46 through the air blowing nozzle 45, thereby driving the rotating shaft 41 to rotate. When the rotating shaft 41 rotates, it drives the fixed sleeve 42 and the slapping plate 43 to rotate, thereby slapping the fallen scraps, so that they are in a loose state and fall into the interior of the collection box 40;

[0044] A method for forming sintered porous bricks, specifically comprising:

[0045] S1: First, after the raw materials for production are mixed in a certain proportion, they are added into the interior of the hopper 6, and then the strip blank is initially shaped through the conveying of the clamping frame 7 and the shaping of the forming mold 8;

[0046] S2: The preliminarily shaped blank is transported to the interior of the air drying box 9 by the second conveyor 2, and air is supplied to the interior of the air duct 33 by the fan 32. Then, the strip blanks continuously entering the bottom of the air drying box 9 are air-dried and shaped by the blowing rack 34 to prevent them from falling apart during transportation;

[0047] S3: The air-dried and shaped strip blanks enter the bottom surface of the slitting box 14, which is driven downward by the cylinder 12. The strip blanks are cut and shaped by the slitting blades 26 inside the slitting box 14. During the shaping process, the slitting blades 26 can be cleaned to prevent the slitting blades 26 from adhering to the raw materials and affecting the next slitting.

[0048] S4: After the cutting is completed, the blanks that meet the requirements will be transported by the fourth conveyor 4, and then collected uniformly, and finally fired and formed;

[0049] S5: The blanks that do not meet the specified size will fall downward through the gap between the third conveyor rack 3 and the fourth conveyor rack 4, and will be broken up by the rotating beating plate 43 and the fixed sleeve 42, and finally fall into the collection box 40;

[0050] S6: The scraps collected in the collecting box 40 are transported to the inside of the hopper 6 through the conveying pipe 48 and the feeding pipe 49 by the suction pump 47 on one side of the collecting box 40, so as to recycle the raw materials and prevent waste.

[0051] Working principle: when sintered porous bricks are produced, various raw materials are first proportioned, and then the proportioned raw materials are added to the inside of the hopper 6, and then the screw extruder 5 is started. As the screw extruder 5 is started, the raw materials inside the hopper 6 enter the inside of the screw extruder 5, and then are extruded through the screw extruder 5, and the raw materials pass through the forming die 8, thereby extruding a strip-shaped blank through the forming die 8, and then the blank will contact the top surface of the second conveyor rack 2, and will be transported by the second conveyor rack 2 through the air drying box 9 for blowing and shaping to prevent the blank from being shaped. The blank falls apart during transportation, and then enters the top surface of the third conveyor rack 3 through the conveyance of the second conveyor rack 2. When it reaches the top surface of the third conveyor rack 3 and is located below the slitting box 14, the cylinder 12 drives the sealing plate 24 to move downward inside the sealing box 13. When the sealing plate 24 moves downward inside the sealing box 13, the water injected below the sealing plate 24 can be pressed into the inside of the clamping rack 28. At this time, the first one-way solenoid valve on the outer surface of the water inlet pipe 21 is in the closed state, and the second solenoid valve 31 is in the open state. Finally, through the elbow 2 9 and the nozzle 30 spray toward the outer surface of the slitting blade 26 to clean the raw materials adhered to the outer surface of the slitting blade 26. As the sealing plate 24 continues to move downward, when the sealing plate 24 contacts the water inlet frame 25, it cannot move. As the connecting rod 23 is continuously pressed under the push of the cylinder 12, the slitting box 14 can be continuously pushed toward the blank on the top surface of the third conveyor frame 3, and the blank is cut into multiple blocks of the same size by the slitting blade 26. Then, after the slitting is completed, the cylinder 12 cancels the pressure, and the spring under the movable sleeve block 15 is activated. Under the action of the pressure relief valve 22, the slitting box 14 and the sealing box 13 are moved away from the top of the third conveyor rack 3. At this time, the sealing plate 24 is still tightly attached to the top surface of the water inlet rack 25. The block bricks cut on the top surface of the third conveyor rack 3 are transported by the third conveyor rack 3 to the top surface of the fourth conveyor rack 4. The scraps that do not meet the specified size are smaller than normal block bricks. The scraps will fall downward through the gap between the third conveyor rack 3 and the fourth conveyor rack 4, while the block bricks that meet the specified size will be discharged through the transportation of the fourth conveyor rack 4. Finally, the production of porous bricks can be completed by firing.

[0052] When the scrap material falls downward, the output shaft of the cylinder 12 drives the connecting rod 23 to move upward, that is, drives the sealing plate 24 to move upward inside the sealing box 13. At this time, the second solenoid valve 31 is in a closed state, and the first solenoid valves at both ends of the water inlet pipe 21 are in an open state. As the sealing plate 24 moves upward, the water inside the water tank 16 can enter the bottom of the sealing plate 24 through the water delivery pipe 17, the first diversion pipe 18, the first connecting pipe 19, the second connecting pipe 20 and the water inlet pipe 21, that is, the water filling operation of the space below the sealing plate 24 is completed, which is convenient for the lower The slitting blade 26 is cleaned again. At the same time, during the upward movement of the sealing plate 24, the air on the top surface of the sealing plate 24 will be compressed into the inside of the air guide tube 22, and transported by the air guide tube 22 to the inside of the second diversion tube 37, and then transported by the second diversion tube 37 to the inside of the air delivery tube 44 on its bottom surface, and finally blown out to the paddle plate 46 through the blowing nozzle 45, thereby driving the rotating shaft 41 to rotate. When the rotating shaft 41 rotates, it drives the fixed sleeve 42 and the slapping plate 43 to rotate, thereby slapping the fallen scraps, so that they are in a loose state and fall into the inside of the collection box 40.

[0053] When the loose scraps fall into the collection box 40 and are stored to a certain amount, the suction pump 47 can be started to suck the scraps stored in the collection box 40 into the feed pipe 48, and then re-enter the feed pipe 49 through the feed pipe 49, forming a cycle, which can effectively avoid the waste of raw materials.

[0054] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
