[0011] Preferably, the first gear ring is engaged with the first rack in the initial state, and the large gear is engaged with the second rack.

[0012] An operation method of a high-density silica brick high-temperature air permeability test device includes the following steps:

[0013] S1. First, place the high-density silica on the surface of the conveyor belt at one end, and then heat the bottom of the high-density silica brick through a heating plate. When the high-density silica brick moves between the first clamping ring and the second clamping ring, the output shaft of the conveyor belt drives the L-shaped rotating rod to rotate. When the L-shaped rotating rod rotates, it rotates and slides inside the notch rod, and at the same time drives the notch rod to swing up and down with one end of itself as the center. When the notch rod swings, it drives the sector gear to swing and drives the engaged small gear to rotate left and right. When the small gear rotates to the left, it drives the spline rod to rotate. The spline rod drives the first clamping ring to lift the high-density silica brick up a little bit, so that the high-density silica brick is closely attached to the second clamping ring. At this time, the first clamping ring and the second clamping ring tightly clamp the high-density silica brick. Then, rotate the high-density silica brick to the surface of the next conveyor belt through the spline rod again. When the spline rod rotates to the rightmost side, the gravity of the high-density silica brick will act on the surface of the conveyor belt. The first clamping ring and the second clamping ring will loosen the high-density silica brick through a rotation interval between them and the spline rod. At this time, the other side of the high-density silica brick will start to be heated, facilitating the next step;

[0014] S2. After being transported to the surface of the air chamber detection table by another conveyor belt, start the driving cylinder. The driving cylinder drives the sealing box to move downward to completely cover the high-density silica brick. Then, start the air pump to input a certain amount of gas pressure into the high-density silica brick and the inside of the air chamber detection table. When the gas passes through the high-density silica brick and enters the air chamber detection table, if the airtightness is a qualified value after passing through the gas, the air pressure will slightly push the piston piece. The piston piece drives the rotating rod to slide to the right inside the air chamber detection table. When the rotating rod slides, it drives the first gear ring to slide. When the first gear ring slides, it drives the second gear disk to slide. At this time, the second gear disk will separate from the first gear disk, and at the same time, the second gear ring is not engaged with the large gear and the gear. The first L-shaped rod and the second L-shaped rod will lose the power source, and the spring will pull the inclined panel to slide on the surface of the first slide rail to the middle of the support frame. At this time, the inclined panel will not completely squeeze the spring slide rod, and the right inclined rod and the left inclined rod will be above another conveyor belt. In this way, the qualified high-density silica brick will be transported to the qualified area through the conveyor belt;

[0015] S3. When the airtightness is insufficient, the gas in the sealing box is difficult to pass through the high-density silica brick. In this way, the gas pressure entering the air chamber detection table will decrease, so it is difficult to push the piston piece. When the piston piece is not under pressure, the first spring will push the piston piece to reset and drive the rotating rod to reset at the same time. In this way, the rotating rod will drive the first gear ring to engage with the first rack. At the same time, the second gear disk fixed to the side of the first gear ring will engage with the first gear disk. Then, the output shaft of the conveyor belt drives the first gear disk to rotate through the first transmission belt. When the first gear disk rotates, it drives the engaged second gear disk rotating rod. The second gear disk drives the first gear ring to rotate. When the first gear ring rotates, it drives the first rack to slide on the surface of the second slide rod. At the same time, when the first rack moves to the top through the first gear ring, the first gear ring will continuously squeeze the tooth. When the tooth is squeezed, it will slide in the chute, driving the first rack to be in a continuously squeezed state. When the second slide rod slides, it drives the T-shaped rod to pull the inclined panel to slide on the upper end of the support frame. When the inclined panel slides, it will squeeze one of the spring slide rods. The spring slide rod slides downward on the surface of the support plate and drives the right inclined rod to slide downward. When the right inclined rod slides downward, it will fit with the conveyor belt. In this way, the high-density silica brick with insufficient airtightness will be squeezed by the right inclined rod into the unqualified and airtightness-insufficient area when being transported, separating from the qualified high-density silica brick;

[0016] S4. When the airtightness is too high, the gas in the sealed box can easily pass through the highly dense silica brick. As a result, the air pressure entering the air chamber detection table will increase, which will push the piston piece. When the piston piece is under pressure, the air pressure will push the piston piece to reset and at the same time push the rotating rod. In this way, the rotating rod will drive the second gear ring to mesh with the large gear and the gear. Then, the output shaft of the conveyor belt drives the gear to rotate through the second conveyor belt. When the gear rotates, it drives the second gear ring to rotate. When the second gear ring rotates, it drives the large gear to rotate. When the large gear rotates, it drives the engaged second rack to slide on the surface of the first slide bar. When the first slide bar slides, it drives the T-shaped rod to push the inclined panel. The inclined panel slides on the upper end of the support frame. When the inclined panel slides, it will squeeze 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 highly dense silica brick with too high airtightness will be squeezed by the left inclined rod into the unqualified area with too high airtightness during transportation and separated from the qualified highly dense silica bricks.

[0017] S5. After the inflation is completed, the drive shaft of the conveyor belt drives the worm to rotate. When the worm rotates, it drives the worm wheel to rotate. When the worm wheel rotates, it drives the reciprocating lead screw to rotate. When the reciprocating lead screw rotates, it drives the support rod to move reciprocally. When the support rod moves, it drives the push rod to slide inside the inclined chute and push the highly dense silica brick along the inclined surface of the inclined chute to the surface of the next conveyor belt.

[0018] S6. During this process, when the sealed box slides downward, it drives the connecting rod to slide downward and at the same time drives the pawl to slide downward. At this time, the pawl does not mesh with the ratchet wheel, and the annular valve will also be in a closed state at this time. In this way, there will be no air leakage when the air chamber detection table intakes air, ensuring that the highly dense silica brick with too high airtightness will not enter the qualified area during transportation. When the sealed box moves upward, it drives the connecting rod to move upward at the same time. The connecting rod drives the pawl to move upward at the same time and mesh with the ratchet wheel, and drives the ratchet wheel to rotate. When the ratchet wheel rotates, it drives the annular valve to rotate, opens the air outlet pipe, discharges the air in the air chamber detection table, and restores to the initial state. When the pawl completely slides past the ratchet wheel, the annular valve will restore to the initial state through its own torsion spring rod.

[0019] In the present invention, when the first L-shaped rod and the second L-shaped rod lose the power source, the spring will pull the inclined panel to slide on the surface of the first slide rail and slide to the middle of the support frame. At this time, the inclined panel 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 highly dense silica bricks will be transported to the qualified area through the conveyor belt.

[0020] In the present invention, when the inclined panel slides, it will squeeze one of the spring sliders. The spring slider slides downward on the surface of the support plate and drives the right inclined rod to slide downward. When the right inclined rod slides downward, it will be in contact with the conveyor belt. In this way, the high-density silica bricks with insufficient airtightness will be squeezed by the right inclined rod into the area with unqualified and insufficient airtightness during transportation and separated from the qualified high-density silica bricks.

[0021] In the present invention, when the inclined panel slides, it will squeeze the other spring slider. The spring slider 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 be in contact with the conveyor belt. In this way, the high-density silica bricks with excessive airtightness will be squeezed by the left inclined rod into the area with unqualified and excessive airtightness during transportation and separated from the qualified high-density silica bricks.

[0047] The usage method and advantages of the present invention: For the high-temperature air permeability performance testing device and operation method of highly dense silica bricks, during use, the working process is as follows:

[0048] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 、Figure 14 , Figure 15 , Figure 16 as shown in

[0049] An operation method of a high-density silica brick high-temperature air permeability test device includes the following steps:

[0050] S1. First, place the high-density silica brick on the surface of the conveyor belt 3 at one end, and then heat the bottom of the high-density silica brick through the heating plate 4. When the high-density silica brick moves between the first clamping ring 55 and the second clamping ring 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. When the notch rod 52 swings, it drives the sector gear 53 to swing and drives the meshing pinion 57 to rotate left and right. When the pinion 57 rotates to the left, it drives the spline rod 54 to rotate. The spline rod 54 drives the first clamping ring 55 to lift the high-density silica brick up a little bit, so that the high-density silica brick is in close contact with the second clamping ring 56. At this time, the first clamping ring 55 and the second clamping ring 56 tightly clamp the high-density silica brick. Then, rotate the spline rod 54 again to transport and rotate the high-density silica brick to the surface of the next conveyor belt 3. When the spline rod 54 rotates to the rightmost side, the gravity of the high-density silica brick will be on the surface of the conveyor belt 3. The first clamping ring 55 and the second clamping ring 56 will loosen the high-density silica brick through a rotation interval with the spline rod 54. At this time, the other side of the high-density silica brick will start to be heated, facilitating the next step;

[0051] S2. After being transported to the surface of the air chamber detection table 101 by another conveyor belt 3, start the driving cylinder 82. The driving cylinder 82 drives the sealing box 83 to move downward to completely cover the high-density silica brick. Then, start the air pump 84 to input a certain amount of gas pressure into the high-density silica brick and the inside of the air chamber detection table 101. When the gas passes through the high-density silica brick and enters the air chamber detection table 101, and the airtightness is a qualified value after passing through the gas, the air pressure will slightly push the piston piece 106. The piston piece 106 drives the rotating rod 104 to slide to the right inside the air chamber detection table 101. When the rotating rod 104 slides, it drives the first gear ring 105 to slide. When the first gear ring 105 slides, it drives the second gear disk 92 to slide. At this time, the second gear disk 92 will be separated from the first gear disk 91, and at the same time, the second gear ring 107 is not meshed with the large gear 96 and the gear 97. The first L-shaped rod 75 and the second L-shaped rod 76 will lose the power source. The spring 73 will pull the inclined panel 72 to slide on the surface of the first slide rail 71 and slide to the middle of the support frame 2. At this time, the inclined panel 72 will not completely squeeze the spring slide rod 78, and the right inclined rod 79 and the left inclined rod 710 will be above the other conveyor belt 3. In this way, the qualified high-density silica brick will be transported to the qualified area through the conveyor belt 3;

[0052] S3. When the airtightness is insufficient, it is difficult for the gas in the sealing box 83 to pass through the highly dense silica brick. As a result, the air pressure of the gas entering the air chamber detection table 101 will decrease. Therefore, it is difficult to push the piston piece 106. When the piston piece 106 is not under pressure, the spring 108 will push the piston piece 106 to reset, and at the same time drive the rotating rod 104 to reset. In this way, the rotating rod 104 will drive the first gear ring 105 to engage with the first rack 94. At the same time, the second gear disc 92 fixed to the side of the first gear ring 105 will engage with the first gear disc 91. Then, the output shaft of the conveyor belt 3 drives the first gear disc 91 to rotate through the first transmission belt 93. When the first gear disc 91 rotates, it drives the engaged second gear disc 92 to rotate. The second gear disc 92 drives the first gear ring 105 to rotate. When the first gear ring 105 rotates, it drives the first rack 94 to slide on the surface of the second slide bar 712. At the same time, when the first rack 94 moves to the top through the first gear ring 105, the first gear ring 105 will continuously squeeze the tooth 910. When the tooth 910 is squeezed, it will slide in the chute 99, driving the first rack 94 to be in a continuously squeezed state. When the second slide bar 712 slides, it drives the T-shaped rod 74 to pull the inclined panel 72 to slide on the upper end of the support frame 2. When the inclined panel 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 be in contact with the conveyor belt 3. In this way, the highly dense silica brick with insufficient airtightness will be squeezed by the right inclined rod 79 into the unqualified area with insufficient airtightness during transportation and separated from the qualified highly dense silica bricks;

[0053] S4. When the airtightness is too high, the gas in the sealing box 83 can easily pass through the highly dense silica brick. As a result, the air pressure of the gas entering the air chamber detection table 101 will increase. Therefore, it will push the piston piece 106. When the piston piece 106 is under pressure, the air pressure will push the piston piece 106 to reset and at the same time push the rotating rod 104. In this way, the rotating rod 104 will drive the second gear ring 107 to engage with the large gear 96 and the gear 97. Then, the output shaft of the conveyor belt 3 drives the gear 97 to rotate through the second transmission belt 98. When the gear 97 rotates, it drives the second gear ring 107 to rotate. When the second gear ring 107 rotates, it drives the large gear 96 to rotate. When the large gear 96 rotates, it drives the engaged second rack 95 to slide on the surface of the first slide bar 711. When the first slide bar 711 slides, it drives the T-shaped rod 74 to push the inclined panel 72. The inclined panel 72 slides on the upper end of the support frame 2. When the inclined panel 72 slides, it will squeeze the other 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 be in contact with the conveyor belt 3. In this way, the highly dense silica brick with too high airtightness will be squeezed by the left inclined rod 710 into the unqualified area with too high airtightness during transportation and separated from the qualified highly dense silica bricks;

[0054] S5. After inflation is completed, the drive 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 lead screw 63 to rotate. When the reciprocating lead screw 63 rotates, it drives the support rod 64 to move reciprocally. When the support rod 64 moves, it drives the push rod 65 to slide inside the inclined chute 61 and push the high-density silica brick along the inclined surface of the inclined chute 61 to the surface of the next conveyor belt 3.

[0055] S6. During this process, when the sealing box 83 slides downward, it drives the connecting rod 85 to slide downward and simultaneously drives the pawl 1012 to slide downward. At this time, the pawl 1012 is not engaged with the ratchet wheel 1011, and the annular valve 1010 will also be in a closed state at this time. In this way, there will be no air leakage when the air chamber inspection table 101 intakes air, ensuring that the high-density silica brick with excessive airtightness will not enter the qualified area during transportation. When the sealing box 83 moves upward, it drives the connecting rod 85 to move upward simultaneously. The connecting rod 85 drives the pawl 1012 to move upward simultaneously and engage with the ratchet wheel 1011, and drives the ratchet wheel 1011 to rotate. When the ratchet wheel 1011 rotates, it drives the annular valve 1010 to rotate, opens the air outlet pipe 109, discharges the air in the air chamber inspection table 101, and restores it to the initial state. When the pawl 1012 completely slides past the ratchet wheel 1011, the annular valve 1010 will restore to the initial state through its own torsion spring rod.

5. A method for operating a high-temperature air permeability testing device for high-density silica bricks, which uses a high-temperature air permeability testing device for high-density silica bricks as described in claim 4, characterized in that, It includes the following steps: S1. First, place the high-density silica brick on the surface of the conveyor belt (3) at one end, and then heat the bottom of the high-density silica brick through the heating plate (4). When the high-density silica brick moves between the first clamping ring (55) and the second clamping ring (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. When the notch rod (52) swings, it drives the sector gear (53) to swing and drives the engaged small gear (57) to rotate left and right. When the small gear (57) rotates to the left, it drives the spline rod (54) to rotate. The spline rod (54) drives the first clamping ring (55) to lift the high-density silica brick up a little bit, so that the high-density silica brick is closely attached to the second clamping ring (56). At this time, the first clamping ring (55) and the second clamping ring (56) tightly clamp the high-density silica brick. Then, rotate the spline rod (54) again to transport and rotate the high-density silica brick to the surface of the next conveyor belt (3). At this time, the other side of the high-density silica brick will start to be heated, facilitating the next step. S2. After being transported to the surface of the air cavity detection table (101) by another conveyor belt (3), start the driving cylinder (82). The driving cylinder (82) drives the sealing box (83) to move downward to completely cover the high-density silica brick. Then, start the air pump (84) to input a certain amount of gas pressure into the high-density silica brick and the inside of the air cavity detection table (101). When the gas passes through the high-density silica brick and enters the air cavity detection table (101), if the airtightness after passing is the qualified value, the air pressure will slightly push the piston piece (106). The piston piece (106) drives the rotating rod (104) to slide to the right inside the air cavity detection table (101). When the rotating rod (104) slides, it drives the first gear ring (105) to slide. When the first gear ring (105) slides, it drives the second gear disc (92) to slide. At this time, the second gear disc (92) will separate from the first gear disc (91), and at the same time, the second gear ring (107) is not engaged with the large gear (96) and the gear (97). The first L-shaped rod (75) and the second L-shaped rod (76) will lose the power source, and the spring (73) will pull the inclined panel (72) to slide on the surface of the first slide rail (71) to the middle of the support frame (2). At this time, the inclined panel (72) will not completely squeeze the spring slide rod (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 silica brick will be transported to the qualified area by the conveyor belt (3); S3. When the airtightness is insufficient, it is difficult for the gas in the sealing box (83) to pass through the highly dense silica brick. As a result, the air pressure of the gas entering the air chamber detection table (101) will decrease, making it difficult to push the piston piece (106). When the piston piece (106) is not under pressure, the first spring (108) will push the piston piece (106) back to its original position, and at the same time drive the rotating rod (104) to return to its original position. In this way, the rotating rod (104) will drive the first gear ring (105) to engage with the first rack (94). At the same time, the second gear disk (92) fixed to the side of the first gear ring (105) will engage with the first gear disk (91). Then, the output shaft of the conveyor belt (3) drives the first gear disk (91) to rotate through the first transmission belt (93). When the first gear disk (91) rotates, it drives the engaged second gear disk (92) to rotate. The second gear disk (92) drives the first gear ring (105) to rotate. When the first gear ring (105) rotates, it drives the first rack (94) to slide on the surface of the second sliding rod (712). At the same time, when the first rack (94) moves to the top through the first gear ring (105), the first gear ring (105) will continuously squeeze the tooth (910). When the tooth (910) is squeezed, it will slide in the chute (99), driving the first rack (94) to be continuously squeezed. When the first rack (94) slides, it drives the T-shaped rod (74) to pull the inclined panel (72) to slide on the upper end of the support frame (2). When the inclined panel (72) slides, it will squeeze one of the spring sliding rods (78). The spring sliding rod (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 be in contact with the conveyor belt (3). In this way, the highly dense silica brick with insufficient airtightness will be squeezed by the right inclined rod (79) into the unqualified and airtightness-insufficient area during transportation and separated from the qualified highly dense silica bricks; S4. When the airtightness is too high, the gas in the sealing box (83) can easily pass through the highly dense silica brick. As a result, the air pressure of the gas entering the air chamber detection table (101) will increase. Therefore, it will push the piston piece (106). When the piston piece (106) is under pressure, the air pressure will push the piston piece (106) to reset and at the same time push the rotating rod (104). In this way, the rotating rod (104) will drive the second gear ring (107) to mesh with the large gear (96) and the gear (97). Then, the output shaft of the conveyor belt (3) drives the gear (97) to rotate through the second transmission belt (98). When the gear (97) rotates, it drives the second gear ring (107) to rotate. When the second gear ring (107) rotates, it drives the large gear (96) to rotate. When the large gear (96) rotates, it drives the engaged second rack (95) to slide on the surface of the first slide bar (711). When the second rack (95) slides, it drives the T-shaped rod (74) to push the inclined panel (72). The inclined panel (72) slides on the upper end of the support frame (2). When the inclined panel (72) slides, it will squeeze 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 be in contact with the conveyor belt (3). In this way, the highly dense silica brick with too high airtightness will be squeezed by the left inclined rod (710) into the unqualified area with too high airtightness during transportation and separated from the qualified highly dense silica brick; S5. After the inflation is completed, the drive 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 lead screw (63) to rotate. When the reciprocating lead screw (63) rotates, it drives the support rod (64) to move reciprocally. When the support rod (64) moves, it drives the push rod (65) to slide inside the inclined plane chute (61) and push the highly dense silica brick along the inclined plane of the inclined plane chute (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 wheel (1011), and the annular valve (1010) will also be in a closed state at this time. In this way, there will be no air leakage when the air chamber testing bench (101) intakes air, ensuring that the highly dense silica bricks with excessive airtightness will not enter the qualified area during transportation. When the sealing box (83) moves upward, it drives the connecting rod (85) to move upward at the same time. The connecting rod (85) drives the pawl (1012) to move upward at the same time, and engages with the ratchet wheel (1011), and drives the ratchet wheel (1011) to rotate. When the ratchet wheel (1011) rotates, it drives the annular valve (1010) to rotate, opens the air outlet pipe (109), discharges the air in the air chamber testing bench (101), and restores it to the initial state. When the pawl (1012) completely slides past the ratchet wheel (1011), the annular valve (1010) will restore to the initial state through its own torsion spring rod.
