[0002] Refractory materials are generally divided into two types, namely, unshaped refractory materials and shaped refractory materials. Unshaped refractory materials are also called castables, which are mixed powder particles composed of multiple aggregates or aggregates and one or more binders. When used, they must be mixed with one or more liquids to be evenly mixed and have strong fluidity. Shaped refractory materials generally refer to refractory bricks, which have standard shapes and can also be temporarily processed when built and cut according to needs. For hot blast furnaces, refractory bricks are needed in the production process to achieve heat conduction and absorb and purify exhaust gas.

[0003] Patent document with patent number CN201521072580.1 discloses a refractory brick, including an outer brick body and a high temperature resistant layer, the high temperature resistant layer is located in the outer brick body, the outer brick body has an upper end face, a lower end face and a side face, the projections of the upper end face and the lower end face on the horizontal plane overlap each other, and at least one air permeable component is provided on the upper end face, the lower end face or the side face of the outer brick body, and the air permeable component does not contact the high temperature resistant layer. When the refractory bricks of this structure are stacked, an exhaust channel is formed between the air permeable components on adjacent refractory bricks, which is conducive to timely discharge of hot air in the furnace, has good heat conduction effect, and can also timely remove moisture and humidity inside the brick body through the air permeable components.

[0004] However, in actual use, the inventors found that the air pores of the refractory bricks mostly extend in a straight line, and the residence time of the exhaust gas in the air pores is short, resulting in poor adsorption and purification effect of the exhaust gas. Summary of the invention

It can continuously and automatically produce refractory bricks with corrugated air holes, and complete the raw material feeding, pressing and molding and demolding and output of the refractory bricks in turn. The structural linkage is good, and refractory bricks can be produced in batches to increase the economic benefits of the enterprise, thereby solving the technical problem that the air holes of the refractory bricks mostly extend in a straight line direction, the residence time of the exhaust gas in the air holes is short, resulting in poor adsorption and purification effect of the exhaust gas.

[0056] In this embodiment, by cooperating with the pipe placement mechanism 5 and the die forming mechanism 6, on the one hand, corrugated air holes can be integrally formed on the refractory bricks, thereby lengthening the residence time of the exhaust gas in the refractory bricks, ensuring more thorough purification of the exhaust gas, improving the adsorption and purification effect of the refractory bricks on the exhaust gas, reducing the impact of the exhaust gas on the environment, and being more environmentally friendly; on the other hand, refractory bricks with corrugated air holes can be continuously and automatically produced, and the raw material feeding, pressing and molding, and demolding and output of the refractory bricks can be completed in turn.

[0058] Further, if Figure 2-4 As shown, the conveyor frame 1 is provided with two conveyor belts 11 arranged side by side and working synchronously, and the gap between the two conveyor belts 11 can allow the lifting rods 25 of the lower mold box 21 and the upper mold box 22 to pass through, so that the lower mold box 21 and the upper mold box 22 are stably arranged on the conveyor belts 11;

[0059] The carrying mechanism 2 includes a lower mold box 21 arranged on the conveyor belt 11, an upper mold box 22 hingedly arranged on the side of the lower mold box 21, two groups of extension rods 23 symmetrically arranged on the outer side wall of the upper mold box 22 and used to drive the upper mold box 22 and the lower mold box 21 to close the mold, a magnet column arranged at the end of the extension rod 23, a semicircular groove 24 opened at the open end of the lower mold box 21 and the open end of the upper mold box 22 and adapted to the hose, two groups of lifting rods 25 respectively passing through and lifting the bottom of the lower mold box 21 and the bottom of the upper mold box 22, two groups of push plates 26 respectively arranged at the upper ends of the lifting rods 25 and correspondingly adapted to the inner walls of the lower mold box 21 and the inner walls of the upper mold box 22, and a first elastic member 27 arranged at the lower end of the lifting rods 25 and used to drive the push plates 26 to reset.

[0060] It should be noted that the lower mold box 21 is fixedly arranged on the conveyor belt 11, and the upper mold box 22 is hingedly arranged on the side of the opening end of the lower mold box 21, so that the lower mold box 21 and the upper mold box 22 can be stably molded.

[0061] In this embodiment, the supporting mechanism 2 is provided to carry the raw materials of the refractory bricks, and to perform mold closing, press molding and demoulding operations on the refractory bricks.

[0062] In detail, the conveyor belt 11 carries the supporting mechanism 2 to move forward, the unloading mechanism 3 injects a certain amount of raw materials into the lower mold box 21 and the upper mold box 22, and the magnet column at the end of the extension rod 23 drives the upper mold box 22 to rotate upward and cover the open end of the lower mold box 21 under the drive of the mold clamping assembly 61. The lifting rods 25 of the upper mold box 22 and the lower mold box 21 drive the two push plates 26 to extrude the refractory bricks into shape under the drive of the extrusion assembly 62.

[0063] Further, if Figure 2-6 As shown, the material discharge mechanism 3 includes an automatic material discharge component 31 which is arranged on the conveying frame 1 through a bracket and contains raw materials, and a pre-pressing component 32 which is clamped on the automatic material discharge component 31 and is used to flatten the raw materials in the upper mold box 22 and the lower mold box 21;

[0064] The automatic blanking assembly 31 includes a first hydraulic component 311 disposed on the bracket, a material storage box 312 disposed at the output end of the first hydraulic component 311, and two sets of automatic injection pipes 313 disposed at the bottom of the material storage box 312 and used to inject raw materials into the upper mold box 22 and the lower mold box 21 respectively;

[0065] It should be noted that the structure and function of the automatic injection tube 313 are both existing technologies and will not be described in detail. It can automatically release a certain amount of raw materials.

[0066] The pre-pressing assembly 32 includes a frame 321 detachably plugged into the outer wall of the storage box 312, a circular plate 322 arranged at the bottom of the frame 321 and used to collect waste generated by the flattening work of the upper mold box 22 and the lower mold box 21, a screw rod 323 rotatably arranged between the frames 321, a spreading plate 324 threadedly passing through the screw rod 323, a pressure roller 325 arranged on one side of the screw rod 323, and a first stepper motor 326 arranged on the outer wall of the frame 321 and used to drive the screw rod 323, and the bottom of the pressure roller 325 and the bottom of the spreading plate 324 are on the same horizontal plane.

[0067] It should be noted that after the pre-pressing assembly 32 pre-presses the raw material in the upper mold box 22 , the pre-pressed raw material in the upper mold box 22 will not fall off during the process of the upper mold box 22 rotating upward to cover the open end of the lower mold box 21 .

[0068] It is worth mentioning that the circular connecting plate 322 is adapted to the upper mold box 22 and the lower mold box 21 arranged side by side, and is used to collect the raw materials dropped by the upper mold box 22 and the lower mold box 21 during the pre-flattening process. The frame 321 detachably plugged into the outer wall of the material storage box 312 can be removed, and the raw materials collected on the circular connecting plate 322 can be recycled and reused.

[0069] In this embodiment, by cooperating with the automatic blanking assembly 31 and the pre-pressing assembly 32, on the one hand, a certain amount of raw materials can be automatically injected into the upper mold box 22 and the lower mold box 21, and the raw materials in the upper mold box 22 and the lower mold box 21 can be spread during the injection process to ensure that the raw materials can be fully filled in the upper mold box 22 and the lower mold box 21, thereby improving the molding effect of the refractory bricks; on the other hand, the raw materials in the upper mold box 22 and the lower mold box 21 can be pre-pressed to facilitate the closing of the upper mold box 22 and the lower mold box 21, and to facilitate the indentation assembly 41 to press corrugated grooves on the surface of the raw materials.

[0070] In detail, the conveyor belt 11 carries the supporting mechanism 2 forward to the position below the unloading mechanism 3 and then stops operating. The first hydraulic component 311 drives the automatic injection pipe 313 and the pre-pressing assembly 32 to descend, so that the circular connecting plate 322 falls onto the extension rod 23 of the upper mold box 22. At this time, the spreading plate 324 is flush with the opening ends of the upper mold box 22 and the lower mold box 21, and the automatic injection pipe 313 injects a certain amount of raw materials into the upper mold box 22 and the lower mold box 21. During the injection process, the first stepper motor 326 drives the screw rod 323 to rotate back and forth in both directions, so that the screw rod 323 drives the spreading plate 324 to spread the raw materials injected into the upper mold box 22 and the lower mold box 21. At the same time, the pressure roller 325 pre-presses the raw materials. The raw materials that fall during the pre-pressing process fall onto the circular connecting plate 322. Then, the first hydraulic component 311 drives the automatic injection pipe 313 and the pre-pressing assembly 32 to rise and reset for the next use.

[0071] Further, if Figure 2-3 and Figure 7-9 As shown, the groove pressing mechanism 4 includes an indentation component 41 arranged on the conveying frame 1 through a bracket and a material cleaning component 42 which is lifted and sleeved on the indentation component 41 and is used to clean the raw materials in the semicircular grooves 24 of the upper mold box 22 and the lower mold box 21;

[0072] The indentation assembly 41 includes a second hydraulic component 411 disposed on the bracket, a lifting plate 412 disposed at the output end of the second hydraulic component 411, and two groups of corrugated ridges 413 symmetrically disposed at the bottom of the lifting plate 412;

[0073] The material cleaning assembly 42 includes a lifting frame 421 sleeved on the outer wall of the lifting plate 412, two groups of sliders 422 symmetrically arranged on the side walls of the lifting plate 412, two groups of sliding holes symmetrically opened on the side walls of the lifting frame 421 and adapted to the sliders 422, four groups of L-shaped ear plates symmetrically arranged on the side walls of the lifting frame 421, an insertion strip 423 penetrating and slidingly arranged on the L-shaped ear plates and adapted to the semicircular groove 24, a through hole 424 opened on the side walls of the lifting frame 421 for the insertion strip 423 to pass through, a second elastic member 425 arranged between the end of the insertion strip 423 and the L-shaped ear plate and used to drive the insertion strip 423 to reset, two groups of L-shaped support rods 426 symmetrically arranged on the sliders 422, and a driving block 427 arranged at the end of the L-shaped support rod 426, and a slope surface for driving the insertion strip 423 to work is opened on the side of the driving block 427.

[0074] It should be noted that when the lifting frame 421 descends to the extension rod 23 of the upper mold box 22 , the inserting strips 423 are located at one side of the semicircular grooves 24 of the upper mold box 22 and the lower mold box 21 .

[0075] In this embodiment, by cooperating with the indentation component 41 and the cleaning component 42, a corrugated groove can be pressed out on the pre-flattened raw material surface, so as to limit the corrugated hose falling to the raw material surface. Before the indentation work, the semicircular grooves 24 of the upper mold box 22 and the lower mold box 21 are cleaned first to facilitate the semicircular grooves 24 to accommodate the hose.

[0076] In detail, the conveyor belt 11 carries the carrying mechanism 2 forward to the position below the groove pressing mechanism 4 and then stops operating. The second hydraulic component 411 drives the lifting plate 412 and the cleaning component 42 to descend, so that the lifting frame 421 first descends to the extension rod 23 of the upper mold box 22, and the lifting plate 412 continues to descend, so that the slider 422 descends with the driving block 427 through the L-shaped support rod 426, and the driving block 427 drives the insertion strip 423 to move inward, so that the insertion strip 423 first passes through the through hole 424 on the side wall of the lifting frame 421, and then is inserted into the semicircular groove 24 of the upper mold box 22 and the lower mold box 21, and the raw material in the semicircular groove 24 is cleaned up. After the lifting plate 412 descends to the open end of the upper mold box 22 and the lower mold box 21, the corrugated convex strip 413 presses out a corrugated groove on the surface of the pre-flattened raw material. Finally, the second hydraulic component 411 drives the lifting plate 412 and the cleaning component 42 to rise and reset for the next use.

[0077] Further, if Figure 2 and Fig.10 As shown, the transmission assembly 51 includes a transmission frame 511 arranged on the bracket through a bracket and a chain arranged on the transmission frame 511;

[0078] The lifting assembly 52 includes a third hydraulic component 521 disposed on the chain, a hanging frame 522 disposed at the output end of the third hydraulic component 521 , and a hanging plate 523 disposed at the bottom of the hanging frame 522 .

[0079] In this embodiment, by cooperating with the transmission assembly 51 and the lifting assembly 52, the tube winding assembly 55 can be driven to move synchronously with the supporting mechanism 2 on the conveyor belt 11, and the tube winding assembly 55 can be driven to descend, thereby releasing the corrugated hose on the supporting mechanism 2 on the conveyor belt 11 in turn.

[0080] Further, if Figure 10-14 As shown, the winding assembly 53 includes a hollow winding roller 531 which is arranged at the bottom of the hanging plate 523 through two mounting plates and is used to wind up and release the hose, a magnet block 71 arranged at one end of the hose 7, an automatic exhaust valve arranged on the magnet block 71, a second stepper motor 532 arranged on one of the mounting plates and used to drive the hollow winding roller 531 to work, and a blower 533 arranged on another of the mounting plates and connected to the interior of the hollow winding roller 531, and the other end of the hose 7 is fixedly connected to the interior of the hollow winding roller 531.

[0081] It should be noted that the structures and functions of the automatic exhaust valve and the blower 533 are prior art and will not be described in detail.

[0082] It is worth mentioning that the length of the hose 7 on the hollow winding roller 531 is designed in advance. After the hose 7 is wound into a corrugated shape and falls into the corrugated groove of the lower mold box 21, the lifting assembly 52 drives the hollow winding roller 531 to rise and reset. During the rising and resetting process, the hollow winding roller 531 continues to release the remaining hose. When the hollow winding roller 531 is reset, the remaining hose is completely released, which is convenient for the blower 533 to inflate the hose through the hollow winding roller 531, so that the corrugated hose in the upper mold box 22 and the lower mold box 21 expands outward, thereby forming the corrugated air vents.

[0083] The introduction tube assembly 54 includes a first traction unit 541 disposed at the bottom of the hanging plate 523 and used to introduce the hose into the winding tube assembly 55, and a second traction unit 542 disposed at the bottom of the hanging plate 523 and used to lead the hose out of the winding tube assembly 55;

[0084] The first traction unit 541 includes a first vertical plate 5411 arranged at the bottom of the hanging plate 523, a guide wheel 5412 arranged on the first vertical plate 5411 and located at one side of the hollow winding roller 531, a driven wheel and a driving wheel 5413 arranged on the first vertical plate 5411, a fourth hydraulic component 5414 arranged on the first vertical plate 5411, and a traction plate 5415 arranged on the output shaft of the fourth hydraulic component 5414 and used to clamp the magnet block 71, the traction plate 5415 is located at one side of the lower end of the second electromagnet roller 552, and the driving wheel 5413 is driven by an existing motor;

[0085] The second traction unit 542 includes a second vertical plate 5421 disposed at the bottom of the hanging plate 523 , a fifth hydraulic component 5422 disposed on the second vertical plate 5421 , and a first electromagnet block 5423 disposed on the output shaft of the fifth hydraulic component 5422 and used to attract the magnet block 71 .

[0086] In this embodiment, by cooperating with the reeling assembly 53 and the guide tube assembly 54, the hose can be automatically introduced onto the winding tube assembly 55. After the winding tube assembly 55 winds the hose into a corrugated shape, the hose is led out of the winding tube assembly 55, so that the corrugated hose is formed.

[0087] In detail, the second stepper motor 532 drives the hollow winding roller 531 to release the hose, and the driving wheel 5413 and the driven wheel cooperate to transport the hose forward. At the same time, the fourth hydraulic component 5414 drives the traction plate 5415 to move toward the winding tube assembly 55, so that the traction plate 5415 pulls the hose end to move onto the winding tube assembly 55 through the magnet block 71. After the winding tube assembly 55 winds the hose into a corrugated shape, the fifth hydraulic component 5422 drives the first electromagnet block 5423 to move toward the winding tube assembly 55. At the same time, the first electromagnet block 5423 is magnetic after being energized, so that the first electromagnet block 5423 magnetically attracts the magnet block 71 at the end of the hose. The pressing piece 5422 then drives the first electromagnet block 5423 to reset, thereby forming the corrugated hose. After the corrugated hose falls as a whole into the corrugated groove of the lower mold box 21 and the upper mold box 22 and the lower mold box 21 are closed, the blower 533 inflates air into the hose through the hollow winding roller 531, so that the corrugated hose in the upper mold box 22 and the lower mold box 21 expand outward, thereby forming the corrugated air holes. After the refractory bricks are completely formed, the first electromagnet block 5423 loses its magnetism after power is turned off, the automatic exhaust valve opens, and the hose becomes soft after the gas is discharged. The second stepper motor 532 then drives the hollow winding roller 531 to rewind the exhausted hose for the next use.

[0088] Further, if Figure 10-16 As shown, the tube winding assembly 55 includes a plurality of groups of first electromagnetic rollers 551 which are arranged to rotate side by side at the bottom of the hanging plate 523 and are used to wind the hose into a corrugated shape, two groups of second electromagnetic rollers 552 which are arranged diagonally at the bottom of the hanging plate 523 and are used to pull the hose to turn, a rotating shaft which is arranged at the upper end of the first electromagnetic roller 551 and the upper end of the second electromagnetic roller 552 and which meshes with the driven gear 553 in sequence from left to right, a third stepping motor 554 which is arranged on the hanging frame 522 and is used to drive the driven gear 553, and a retractable support unit 555 which is arranged at the lower end of the first electromagnetic roller 551 and the lower end of the second electromagnetic roller 552 and is used to support the hose;

[0089] The support unit 555 includes an inner cavity opened at the lower end of the first electromagnetic roller 551 and the lower end of the second electromagnetic roller 552, a hanging plate 5551 arranged inside the inner cavity through a hanger, a plurality of groups of slide grooves 5552 opened on the upper surface of the hanging plate 5551, a moving block 5553 slidably arranged in the slide groove 5552, a retracting rod 5554 arranged on the side of the moving block 5553 and penetrating to the outer peripheral side of the hanging plate 5551, an arc-shaped support plate 5555 arranged at one end of the retracting rod 5554, a shifting rod arranged on the moving block 5553, a fourth stepping motor 5556 arranged at the top of the inner cavity, a power disk 5557 arranged on the output shaft of the fourth stepping motor 5556, and a plurality of groups of arc-shaped driving holes 5558 opened on the power disk 5557 and respectively matched with the shifting rods.

[0090] It should be noted that several groups of first electromagnet rollers 551 and two groups of second electromagnet rollers 552 are energized in sequence from the distance from the first traction unit 541 to the farthest, and then de-energized in sequence, so that the first electromagnet rollers 551 and the second electromagnet rollers 552 cooperate with each other, and pull the hose along the corrugated line through the magnet block 71 in sequence, so that the hose is wound into a corrugated shape.

[0091] In this embodiment, the hose can be automatically wound into a corrugated shape by the cooperation of the winding tube assembly 55 and the guide tube assembly 54.

[0092] In detail, the third stepper motor 554 drives the driven gear 553 to mesh and rotate in sequence, so that several groups of first electromagnetic rollers 551 and two groups of second electromagnetic rollers 552 rotate synchronously. After the first traction unit 541 pulls the magnet block 71 at the end of the hose to the side of the second electromagnetic roller 552, the second electromagnetic roller 552 is energized and has magnetism, so that the second electromagnetic roller 552 magnetically attracts the magnet block 71 at the end of the hose. The second electromagnetic roller 552 pulls the hose through the magnet block 71, so that the hose is wound around the side of the second electromagnetic roller 552 between the arc support plate 5555 and the lower end of the sleeve 563. When the magnet block 71 at the end of the hose moves to the junction of the second electromagnetic roller 552 and the first electromagnetic roller 551, The second electromagnetic roller 552 loses its magnetism after being powered off. At the same time, the first electromagnetic roller 551 becomes magnetic after being powered on, so that the first electromagnetic roller 551 connects with the magnet block 71 at the end of the hose. Then, at the junction of two adjacent first electromagnetic rollers 551, the magnet blocks 71 at the end of the hose are connected in turn, so that the hose is wound into a corrugated shape. After the magnet block 71 at the end of the hose moves to the side of another second electromagnetic roller 552, the second electromagnetic roller 552 rotates a specified angle to adjust the traction direction of the hose end. The third stepper motor 554 stops driving the first electromagnetic roller 551 and the second electromagnetic roller 552 to work. Finally, the second traction unit 542 connects with the magnet block 71 at the end of the hose to complete the winding of the corrugated hose.

[0093] Further, if Figure 10-11 As shown, the push tube assembly 56 includes a sixth hydraulic component 561 arranged on the hanging plate 523, a connecting plate 562 arranged at the output end of the sixth hydraulic component 561, and a plurality of groups of sleeves 563 arranged on the connecting plate 562 and respectively sleeved on the outer wall of the first electromagnetic roller 551 and the outer wall of the second electromagnetic roller 552, and the lower end of the sleeve 563 and the arc support plate 5555 cooperate to limit the corrugated hose.

[0094] In this embodiment, the push tube assembly 56 cooperates with the lifting assembly 52 to automatically push the entire corrugated hose into the corrugated groove of the lower mold box 21 .

[0095] In detail, the third hydraulic component 521 of the lifting assembly 52 drives the tube winding assembly 55, so that the arc-shaped support plate 5555 of the support unit 555 descends to the open end of the lower mold box 21, and then the fourth stepper motor 5556 drives the power disk 5557 to rotate, so that the power disk 5557 drives the arc-shaped support plate 5555 to retract inward to the position directly below the first electromagnetic roller 551 and the second electromagnetic roller 552 through the arc-shaped driving hole 5558, the lever, the moving block 5553 and the retraction rod 5554, and then the sixth hydraulic component 561 drives the sleeve 563 to descend, so that the lower end of the sleeve 563 pushes the hose wound around the first electromagnetic roller 551 and the second electromagnetic roller 552 as a whole into the corrugated groove of the lower mold box 21, and finally, the tube winding assembly 55 rises and resets for the next use.

[0096] Further, if Figure 2 and Figure 17-19 As shown, the die forming mechanism 6 includes a clamping assembly 61 disposed on the conveying frame 1 and used to drive the upper die box 22 and the lower die box 21 to open and close, and an extrusion assembly 62 disposed on the conveying frame 1 and used to drive the push plate 26 to press the refractory bricks into shape;

[0097] The clamping assembly 61 includes two groups of side plates 611 symmetrically arranged on the conveying frame 1, two groups of arc tracks 612 arranged on the side plates 611 and respectively used to limit the extension rod 23 with the upper mold box 22 to open and close at the opening of the lower mold box 21, a straight track 613 connected to the two arc-limiting track ports and used to limit the extension rod 23 with the upper mold box 22 to maintain a closed state at the opening of the lower mold box 21, two groups of disks 614 arranged on the side plates 611 and cocentric with the arc tracks 612, a second electromagnet block 615 arranged on the disk 614 and used to attract the magnet column to drive the extension rod 23, and a fifth stepping motor 616 arranged on the side plates 611 and used to drive the disk 614;

[0098] In this embodiment, the mold closing assembly 61 cooperates with the supporting mechanism 2 to automatically close and open the upper mold box 22 and the lower mold box 21 .

[0099] In detail, the conveyor belt 11 carrying the supporting mechanism 2 moves to the position of the arc track 612 and then stops. The second electromagnet block 615 becomes magnetic after being energized, so that the second electromagnet block 615 magnetically attracts the magnet column at the end of the extension rod 23 of the upper mold box 22. The fifth stepper motor 616 drives the disc 614 to rotate a specified angle, so that the second electromagnet block 615 on the disc 614 drives the upper mold box 22 to rotate upward through the extension rod 23 and cover the open end of the lower mold box 21 to complete the mold closing work. After the extension rod 23 enters the linear track 613, the upper mold box 22 remains in a closed state at the open end of the lower mold box 21, so that the raw materials in the upper mold box 22 and the lower mold box 21 are pressed into refractory bricks.

[0100] Further, if Figure 17-19 As shown, the extrusion assembly 62 includes a first limiting rail 621 which is arranged between the two side plates 611 and used to drive the lifting rod 25 of the upper mold box 22 to descend with the push plate 26 to extrude refractory bricks, a second limiting rail 622 which is arranged between the two side plates 611 and used to drive the lifting rod 25 of the lower mold box 21 to rise with the push plate 26 to extrude refractory bricks, a third limiting rail 623 which is arranged at the output end of the first limiting rail 621 and used to drive the lifting rod 25 of the upper mold box 22 to continue to descend with the push plate 26 to push the formed refractory bricks into the lower mold box 21, and a fourth limiting rail 624 which is arranged at the output end of the second limiting rail 622 and is compatible with the third limiting rail 623.

[0101] In this embodiment, by cooperating with the extrusion assembly 62 and the winding assembly 53, on the one hand, the raw materials in the upper mold box 22 and the lower mold box 21 can be squeezed into refractory bricks, and the refractory brick forming effect is better. At the same time, the hose expands outward after being inflated, so that the corrugated air holes in the refractory bricks are formed, thereby making the refractory bricks with corrugated air holes in one piece; on the other hand, in the process of winding the hose by the winding assembly 53, the end of the hose is exhausted, thereby blowing out the dust in the corrugated air holes, thereby achieving the effect of cleaning the corrugated air holes.

[0102] In detail, when the conveyor belt 11 carries the upper mold box 22 and the lower mold box 21 after the mold is closed and moves to the position of the first limit track 621, the push plates 26 in the upper mold box 22 and the lower mold box 21 squeeze the refractory bricks against each other to form them. At the same time, the blower 533 inflates the hose through the hollow winding roller 531, and the corrugated hose expands outward to form corrugated air holes. The hollow winding roller 531 then winds up the exhaust hose. Then, when the conveyor belt 11 carries the upper mold box 22 and the lower mold box 21 after the mold is closed and moves to the position of the third limit track 623, the push plate 26 pushes the formed refractory bricks into the lower mold box 21 to prevent the upper mold box 22 from interfering with the formed refractory bricks during the mold opening process.
