[0011] An operating method of a high-density silica brick high-temperature air permeability testing device comprises the following steps: S1. First, high-density silicon is placed on the surface of a conveyor belt at one end, and then the bottom of the high-density silicon brick is heated by a heating plate. When the high-density silicon brick moves between the clamping ring 1 and the clamping ring 2, the output shaft of the conveyor belt drives the L-shaped rotating rod to rotate. When the L-shaped rotating rod rotates, it will rotate and slide inside the notch rod, and at the same time drive the notch rod to swing up and down with one end of itself as the center of the circle. When the notch rod swings, it drives the fan gear to swing, and drives the meshing small gear to rotate left and right. When the small gear rotates to the left, it drives the spline rod to rotate, and the spline rod rotates. The key rod drives the clamp ring 1 to lift the high-density silica brick a little bit, so that the high-density silica brick fits tightly with the clamp ring 2. At this time, the clamp ring 1 and the clamp ring 2 tightly clamp the high-density silica brick, and then rotate the spline rod again to transport the high-density silica brick to the surface of the next conveyor belt. When the spline rod rotates to the far right, the gravity of the high-density silica brick will be on the surface of the conveyor belt. The clamp ring 1 and the clamp ring 2 will loosen the high-density silica brick through a rotation interval between the spline rod. At this time, the other side of the high-density silica brick will begin to heat up, which is convenient for the next step; S2. After being transported to the surface of the air cavity inspection table through another conveyor belt, the driving cylinder is started, and the driving cylinder drives the sealing box to move downward to completely cover the high-density silicon bricks. Then, a quantitative gas pressure is input into the high-density silicon bricks and the air cavity inspection table when the air passes through the high-density silicon bricks and enters the air cavity inspection table. The air tightness is qualified after passing through the gas. The air pressure will slightly push the piston plate, and the piston plate drives the rotating rod to slide to the right inside the air cavity inspection table. When the rotating rod slides, it drives the gear ring 1 to slide. When the gear ring 1 slides, it drives the gear disc 2 to slide. At this time, the gear disc 2 will be separated from the gear disc 1, and the gear ring 2 will not mesh with the large gear and the gear. The L-shaped rod 1 and the L-shaped rod 2 will lose the power source, and the spring will pull the inclined plate to slide on the surface of the slide rail 1 and slide to the middle of the support frame. At this time, the inclined plate will not completely squeeze the spring slide bar, and the right inclined rod and the left inclined rod will be above another conveyor belt. In this way, the qualified high-density silicon bricks will be transported to the qualified area through the conveyor belt; S3. When the air tightness is insufficient, it is difficult for the gas in the sealing box to pass through the high-density silicon bricks, so that the air pressure of the gas entering the air cavity test bench will be reduced, making it difficult to push the piston plate. When the piston plate is not under pressure, the spring 1 will push the piston plate to reset, and at the same time drive the rotating rod to reset, so that the rotating rod will drive the gear ring 1 to mesh with the rack 1, and at the same time, the gear plate 2 fixed on the side of the gear ring 1 is meshed with the gear plate 1, and then the output shaft of the conveyor belt drives the gear plate 1 to rotate through the transmission belt 1, and when the gear plate 1 rotates, it drives the meshing gear plate 2 to rotate the rod, and the gear plate 2 drives the gear ring 1 to rotate, and when the gear ring 1 rotates, it drives the rack 1 to slide on the surface of the sliding rod 2 When the rack 1 moves to the top through the gear ring 1, the gear ring 1 will squeeze the teeth all the time. When the teeth are squeezed, they will slide in the slide groove, driving the rack 1 to be squeezed all the time. When the slide bar 2 slides, it drives the T-bar to pull the inclined plate to slide on the upper end of the support frame. When the inclined plate slides, it will squeeze one of the spring slide bars. The spring slide bar slides downward on the surface of the support plate and drives the right inclined bar to slide downward. When the right inclined bar slides downward, it will fit with the conveyor belt, so that the high-density silicon bricks with insufficient air tightness will be squeezed by the right inclined bar into the unqualified and insufficient air tightness area during transportation, and separated from the qualified high-density silicon bricks. S4. When the air tightness is too large, the gas in the sealing box can easily pass through the high-density silicon bricks, so that the air pressure of the gas entering the air cavity detection table will increase, and thus the piston plate will be pushed. When the piston plate is under pressure, the air pressure will push the piston plate to reset and push the rotating rod at the same time. In this way, the rotating rod will drive the gear ring 2 to mesh with the large gear and the gear, and then the output shaft of the conveyor belt drives the gear to rotate through the transmission belt 2. When the gear rotates, it drives the gear ring 2 to rotate. When the gear ring 2 rotates, it drives the large gear to rotate. When the large gear rotates, it drives the meshing rack 2 to slide on the surface of the slide bar 1. When the slide bar 1 slides, it drives the T-bar to push the inclined plate. The inclined plate slides on the upper end of the support frame. When the inclined plate slides, it squeezes another spring slide bar. The spring slide bar slides downward on the surface of the support plate and drives the left inclined rod to slide downward. When the left inclined rod slides downward, it will fit with the conveyor belt. In this way, the high-density silicon bricks with excessive air tightness will be squeezed by the left inclined rod into the unqualified and excessively airtight area during transportation, and separated from the qualified high-density silicon bricks; S5. After the inflation is completed, the driving shaft of the conveyor belt drives the worm to rotate, and the worm drives the worm wheel to rotate, and the worm wheel drives the reciprocating screw to rotate, and the reciprocating screw drives the support rod to move back and forth, and the support rod drives the push rod to slide inside the inclined slide groove, and push the high-density silicon brick along the inclined surface of the inclined slide groove to the surface of the next conveyor belt; S6. During this process, when the sealing box slides downward, it drives the connecting rod to slide downward, and drives the pawl to slide downward at the same time. At this time, the pawl is not engaged with the ratchet, and the annular valve is also in a closed state. In this way, there will be no air leakage when the air cavity test bench takes in air, ensuring that high-density silicon bricks with excessive air tightness will not enter the qualified area during transportation. When the sealing box moves upward, it drives the connecting rod upward at the same time, and the connecting rod drives the pawl upward at the same time, and engages with the ratchet, and drives the ratchet to rotate. When the ratchet rotates, it drives the annular valve to rotate, open the air outlet pipe, let the air in the air cavity test bench leak, and return to its initial state. When the pawl completely slides over the ratchet, the annular valve will return to its initial state through its own torsion spring rod.

[0012] In the present invention, when the L-shaped rod 1 and the L-shaped rod 2 lose their power source, the spring will pull the inclined plate to slide on the surface of the slide rail 1 and slide to the middle of the support frame. At this time, the inclined plate will not completely squeeze the spring slide rod, and the right inclined rod and the left inclined rod will be above another conveyor belt, so that qualified high-density silicon bricks will be transported to the qualified area through the conveyor belt.

[0013] In the present invention, when the inclined plate slides, one of the spring slide bars will be squeezed, and the spring slide bar slides downward on the surface of the support plate, and drives the right inclined bar to slide downward. When the right inclined bar slides downward, it will fit with the conveyor belt, so that the high-density silicon bricks with insufficient airtightness will be squeezed by the right inclined bar into the unqualified and insufficient airtightness area during transportation, and separated from the qualified high-density silicon bricks.

[0014] In the present invention, when the inclined plate slides, another spring slide bar will be squeezed, and the spring slide bar slides downward on the surface of the support plate, and drives the left inclined bar to slide downward. When the left inclined bar slides downward, it will fit with the conveyor belt, so that the high-density silica bricks with excessive airtightness will be squeezed by the left inclined bar into the unqualified and excessively airtight area during transportation, and separated from the qualified high-density silica bricks.

First, high-density silicon is placed on the surface of the conveyor belt 3 at one end, and then the bottom of the high-density silicon brick is heated by the heating plate 4. When the high-density silicon brick moves between the clamping ring 1 55 and the clamping ring 2 56, the output shaft of the conveyor belt 3 drives the L-shaped rotating rod 51 to rotate. When the L-shaped rotating rod 51 rotates, it will rotate and slide inside the notch rod 52, and at the same time drive the notch rod 52 to swing up and down with one end of itself as the center of the circle.

After being transported to the surface of the air cavity detection platform 101 by another conveyor belt 3, the driving cylinder 82 is started, and the driving cylinder 82 drives the sealing box 83 to move downward to completely cover the high-density silica brick, and then the air pump 84 is started to input a certain amount of gas pressure into the high-density silica brick and the inside of the air cavity detection platform 101.

At this time, the inclined plate 72 will not completely squeeze the spring slide bar 78, and the right inclined rod 79 and the left inclined rod 710 will be above another conveyor belt 3, so that the qualified high-density silicon bricks will be transported to the qualified area through the conveyor belt 3; S3. When the air tightness is insufficient, it is difficult for the gas in the sealing box 83 to pass through the high-density silicon bricks, so that the air pressure of the gas entering the air cavity detection platform 101 will be reduced, making it difficult to push the piston plate 106. When the piston plate 106 is not under pressure, the spring 108 will push the piston plate 106 to reset, and at the same time drive the rotating rod 104 to reset, so that the rotating rod 104 will drive the ring gear 105 to mesh with the rack 1 94, and at the same time, the toothed disc 2 92 fixed on the side of the ring gear 105 is meshed with the toothed disc 1 91, and then the output shaft of the conveyor belt 3 drives the toothed disc 1 91 to rotate through the transmission belt 1 93, and when the toothed disc 1 91 rotates, it drives the meshed toothed disc 2 92 to rotate the rod, and the toothed disc 2 92 drives the ring gear 105 to rotate, and when the ring gear 105 rotates, it drives the rack 1 94 on the sliding rod When the second slide bar 712 slides on the surface, and the rack 1 94 moves to the top through the gear ring 105, the gear ring 105 will keep squeezing the teeth 910. When the teeth 910 are squeezed, they will slide in the slide groove 99, driving the rack 1 94 to be in a squeezed state. When the slide bar 712 slides, it drives the T-shaped rod 74 to pull the inclined plate 72 to slide on the upper end of the support frame 2. When the inclined plate 72 slides, it will squeeze one of the spring slide bars 78. The spring slide bar 78 slides downward on the surface of the support plate 77 and drives the right inclined rod 79 to slide downward. When the right inclined rod 79 slides downward, it will fit with the conveyor belt 3. In this way, the high-density silicon bricks with insufficient air tightness will be squeezed by the right inclined rod 79 into the unqualified and insufficient air tightness area during transportation, and separated from the qualified high-density silicon bricks. S4. When the air tightness is too large, the gas in the sealing box 83 can easily pass through the high-density silicon bricks, so that the gas pressure entering the air cavity detection platform 101 will increase, thereby pushing the piston plate 106. When the piston plate 106 is under pressure, the air pressure will push the piston plate 106 to reset and push the rotating rod 104 at the same time. In this way, the rotating rod 104 will drive the ring gear 107 to mesh with the large gear 96 and the gear 97, and then the output shaft of the conveyor belt 3 drives the gear 97 to rotate through the transmission belt 2 98. When the gear 97 rotates, it drives the ring gear 107 to rotate. When the ring gear 107 rotates, it drives the large gear 96 to rotate. When the wheel 96 rotates, it drives the meshing rack 2 95 to slide on the surface of the slide bar 1 711. When the slide bar 1 711 slides, it drives the T-shaped rod 74 to push the inclined plate 72. The inclined plate 72 slides on the upper end of the support frame 2. When the inclined plate 72 slides, it squeezes another spring slide bar 78. The spring slide bar 78 slides downward on the surface of the support plate 77 and drives the left inclined rod 710 to slide downward. When the left inclined rod 710 slides downward, it will fit with the conveyor belt 3. In this way, the high-density silicon bricks with excessive air tightness will be squeezed by the left inclined rod 710 into the unqualified and excessively airtight area during transportation, and separated from the qualified high-density silicon bricks. S5. After the inflation is completed, the driving shaft of the conveyor belt 3 drives the worm 62 to rotate, and the worm 62 drives the worm wheel 66 to rotate, and the worm wheel 66 drives the reciprocating screw 63 to rotate, and the reciprocating screw 63 drives the support rod 64 to move back and forth, and the support rod 64 drives the push rod 65 to slide inside the inclined slide groove 61, and push the high-density silicon brick along the inclined surface of the inclined slide groove 61 to the surface of the next conveyor belt 3; S6. During this process, when the sealing box 83 slides downward, it drives the connecting rod 85 to slide downward, and at the same time drives the pawl 1012 to slide downward. At this time, the pawl 1012 is not engaged with the ratchet 1011, and the annular valve 1010 is also in a closed state. In this way, there will be no air leakage when the air cavity detection platform 101 is intaken, ensuring that high-density silicon bricks with excessive air tightness will not enter the qualified area during transportation. When the sealing box 83 is upward, it drives the connecting rod 85 upward at the same time, and the connecting rod 85 drives the pawl 1012 upward at the same time, and engages with the ratchet 1011, and drives the ratchet 1011 to rotate. When the ratchet 1011 rotates, it drives the annular valve 1010 to rotate, open the air outlet pipe 109, let the air in the air cavity detection platform 101 leak, and restore to the initial state. When the pawl 1012 completely slides over the ratchet 1011, the annular valve 1010 will restore to the initial state through its own torsion spring rod.

8. An operating method of a high-density silica brick high-temperature air permeability testing device, using a high-density silica brick high-temperature air permeability testing device as described in any one of claims 1 to 7, characterized in that: The steps include: S1. First, high-density silicon is placed on the surface of a conveyor belt (3) at one end, and then the bottom of the high-density silicon brick is heated by a heating plate (4). When the high-density silicon brick moves between the clamping ring 1 (55) and the clamping ring 2 (56), the output shaft of the conveyor belt (3) drives the L-shaped rotating rod (51) to rotate. When the L-shaped rotating rod (51) rotates, it rotates and slides inside the notch rod (52), and at the same time drives the notch rod (52) to swing up and down with one end of itself as the center of the circle. When the notch rod (52) swings, it drives the fan gear (53) to swing, and drives the meshing small gear (57) to rotate left and right. When the small gear (57) rotates to the left, it drives the spline rod (54). Rotate, the spline rod (54) drives the clamping ring 1 (55) to lift the high-density silica brick upward a little, so that the high-density silica brick fits tightly with the clamping ring 2 (56). At this time, the clamping ring 1 (55) and the clamping ring 2 (56) tightly clamp the high-density silica brick, and then rotate the spline rod (54) again to transport the high-density silica brick to the surface of the next conveyor belt (3). When the spline rod (54) rotates to the far right, the gravity of the high-density silica brick will be on the surface of the conveyor belt (3), and the clamping ring 1 (55) and the clamping ring 2 (56) will loosen the high-density silica brick through a rotation range between the spline rod (54). At this time, the other side of the high-density silica brick will begin to heat, which is convenient for the next step; S2. After being transported to the surface of the air cavity detection platform (101) by another conveyor belt (3), the driving cylinder (82) is started, and the driving cylinder (82) drives the sealing box (83) to move downward to completely cover the high-density silica brick, and then the air pump (84) is started to input a certain amount of gas pressure into the high-density silica brick and the inside of the air cavity detection platform (101). When the gas passes through the high-density silica brick and enters the air cavity detection platform (101), the air tightness after passing through the gas is qualified. The gas pressure will slightly push the piston plate (106), and the piston plate (106) drives the rotating rod (104) to slide to the right inside the air cavity detection platform (101). When the rotating rod (104) slides, it drives the gear ring (105) to slide. When the gear ring 1 (105) slides, it drives the gear disc 2 (92) to slide. At this time, the gear disc 2 (92) will be separated from the gear disc 1 (91). At the same time, the gear ring 2 (107) is not meshed with the large gear (96) and the gear (97). The L-shaped rod 1 (75) and the L-shaped rod 2 (76) will lose the power source, and the spring (73) will pull the inclined plate (72) to slide on the surface of the slide rail 1 (71) and slide to the middle of the support frame (2). At this time, the inclined plate (72) will not completely squeeze the spring slide bar (78), and the right inclined rod (79) and the left inclined rod (710) will be above another conveyor belt (3). In this way, the qualified high-density silicon bricks will be transported to the qualified area through the conveyor belt (3); S3. When the air tightness is insufficient, it is difficult for the gas in the sealing box (83) to pass through the high-density silica bricks, so that the gas pressure entering the air cavity detection platform (101) will be reduced, and it is difficult to push the piston plate (106). When the piston plate (106) is not under pressure, the spring 1 (108) will push the piston plate (106) to reset, and at the same time drive the rotating rod (104) to reset, so that the rotating rod (104) will drive the gear ring 1 (105) to mesh with the rack 1 (94), and at the same time, the gear plate 2 (92) fixed on the side of the gear ring 1 (105) is meshed with the gear plate 1 (91), and then the output shaft of the conveyor belt (3) drives the gear plate 1 (91) to rotate through the transmission belt 1 (93), and when the gear plate 1 (91) rotates, it drives the meshing gear plate 2 (92) to rotate the rod, and the gear plate 2 (92) drives the gear ring 1 (105) to rotate, and when the gear ring 1 (105) rotates, it drives the rack 1 (94) to rotate. The surface of the second slide bar (712) slides, and when the rack one (94) moves to the top through the gear ring one (105), the gear ring one (105) will continue to squeeze the teeth (910). When the teeth (910) are squeezed, they will slide in the slide groove (99), driving the rack one (94) to be in a squeezed state. When the second slide bar (712) slides, it drives the T-shaped rod (74) to pull the inclined plate (72) to slide on the upper end of the support frame (2). When the inclined plate (72) slides, it squeezes one of the spring slide bars (78). The spring slide bar (78) slides downward on the surface of the support plate (77) and drives the right inclined rod (79) to slide downward. When the right inclined rod (79) slides downward, it will fit with the conveyor belt (3). In this way, high-density silicon bricks with insufficient air tightness will be squeezed by the right inclined rod (79) into the unqualified and insufficient air tightness area during transportation, and separated from the qualified high-density silicon bricks. S4. When the air tightness is too large, the gas in the sealing box (83) can easily pass through the high-density silicon bricks, so that the gas pressure entering the air cavity detection platform (101) will increase, thereby pushing the piston plate (106). When the piston plate (106) is under pressure, the air pressure will push the piston plate (106) to reset, and at the same time push the rotating rod (104), so that the rotating rod (104) will drive the second gear ring (107) to mesh with the large gear (96) and the gear (97), and then the output shaft of the conveyor belt (3) drives the gear (97) to rotate through the second transmission belt (98), and when the gear (97) rotates, it drives the second gear ring (107) to rotate, and when the second gear ring (107) rotates, it drives the large gear (96) to rotate. When the gear (96) rotates, it drives the meshing rack gear 2 (95) to slide on the surface of the slide bar 1 (711). When the slide bar 1 (711) slides, it drives the T-shaped rod (74) to push the inclined plate (72). The inclined plate (72) slides on the upper end of the support frame (2). When the inclined plate (72) slides, it squeezes another spring slide bar (78). The spring slide bar (78) slides downward on the surface of the support plate (77) and drives the left inclined rod (710) to slide downward. When the left inclined rod (710) slides downward, it fits with the conveyor belt (3). In this way, high-density silica bricks with excessive air tightness will be squeezed by the left inclined rod (710) into the unqualified and excessively airtight area during transportation, and separated from the qualified high-density silica bricks. S5. After the inflation is completed, the driving shaft of the conveyor belt (3) drives the worm (62) to rotate. When the worm (62) rotates, it drives the worm wheel (66) to rotate. When the worm wheel (66) rotates, it drives the reciprocating screw (63) to rotate. When the reciprocating screw (63) rotates, it drives the support rod (64) to move back and forth. When the support rod (64) moves, it drives the push rod (65) to slide inside the inclined slide groove (61) and push the high-density silica brick along the inclined surface of the inclined slide groove (61) to the surface of the next conveyor belt (3); S6. During this process, when the sealing box (83) slides downward, it drives the connecting rod (85) to slide downward, and at the same time drives the pawl (1012) to slide downward. At this time, the pawl (1012) does not engage with the ratchet (1011), and the annular valve (1010) is also in a closed state. In this way, when the air cavity test bench (101) is inhaled, there will be no air leakage, ensuring that the high-density silica bricks with excessive air tightness will not enter the qualified area during transportation. When the sealing box (83) moves upward, it drives the connecting rod ( 85) move upward at the same time, the connecting rod (85) drives the pawl (1012) to move upward at the same time, and meshes with the ratchet (1011), and drives the ratchet (1011) to rotate. When the ratchet (1011) rotates, the annular valve (1010) is driven to rotate, and the air outlet pipe (109) is opened, so that the air in the air cavity detection platform (101) is vented and restored to the initial state. When the pawl (1012) completely slides over the ratchet (1011), the annular valve (1010) is restored to the initial state through its own torsion spring rod.
