Description

Technical Field

[0002] A type of inorganic non-metallic material with a refractoriness of not less than 1580℃. Refractoriness refers to the Celsius temperature at which a cone-shaped specimen of a refractory material can resist high temperature without softening and melting under no load. However, the definition of refractoriness alone cannot fully describe refractory materials. 1580℃ is not absolute. It is now defined as any material whose physical and chemical properties allow it to be used in a high temperature environment. Carbon fiber tubes are also called carbon fiber tubes, carbon tubes, and carbon fiber tubes.

[0027] A through hole 21 is opened on the partition 2, and a fixing component for closure and adjustment is arranged in the through hole 21 on the partition 2, and the fixing component includes a support block 5, and a first transmission screw 51 is rotatably connected between the two support blocks 5 through a bearing. The first transmission screw 51 is a double-screw structure and the thread rotation directions are opposite. The upper and lower sides of the first transmission screw 51 are both sleeved with a first connecting block 52, and the end of the first connecting block 52 is welded with a first clamping block 53. The first transmission screw 51 and the first connecting block 52 are connected by internal and external threads, and a first motor is installed at one end of the first transmission screw 51.

[0028] The first clamping block 53 is in an arc block structure, a fiber tube is fitted between the two first clamping blocks 53, a first guide rod 54 is welded between the two support blocks 5, the first guide rod 54 passes through the first connecting block 52, and the first transmission screw 51 is rotated by starting the first motor, thereby driving the first connecting blocks 52 on both sides to move closer to or away from each other, so that the first clamping blocks 53 clamp the fiber tube at the same time.

[0029] Slide grooves are provided on both sides of the through hole 21 on the partition 2. A second transmission screw 55 is rotatably connected to the partition 2 in the slide groove through a bearing. The second transmission screw 55 has a double-screw structure and the threads have opposite rotation directions. Second connecting blocks 56 are sleeved on the left and right sides of the second transmission screw 55. A second clamping block 57 is welded to the end of the second connecting block 56. The second transmission screw 55 and the second connecting block 56 are connected by internal and external threads, and a second motor is installed at one end of the second transmission screw 55.

[0030] A second guide rod 58 is welded in the slide groove on the partition 2, and the second guide rod 58 passes through the second connecting block 56. The second clamping block 57 is an arc block structure and is staggered and overlapped with the first clamping block 53. The second transmission screw 5 is rotated by starting the second motor, thereby driving the second connecting blocks 56 on both sides to approach or move away from each other, so that the second clamping block 57 clamps the fiber tube at the same time. The second clamping block 57 and the first clamping block 53 are staggered and overlapped to form a relatively sealed structure of the through hole on the partition 2, and it is also suitable for clamping and fixing fiber tubes with different diameters, so as to facilitate the rapid refractory fiber test and inspection of the fiber tube. It is particularly noted that the multiple diameters are within a certain range according to the size.

[0031] A refrigeration device 6 is installed on the top of the test and detection box 1, and a cold air pipe 61 is fixedly connected to one side of the refrigeration device 6. A delivery pump is installed on the cold air pipe 61, and an air outlet pipe 62 is provided on one side of the test and detection box 1. One end of the cold air pipe 61 and the air outlet pipe 62 are both connected to the interior of the test and detection box 1. When the delivery pump is started, the cold air in the refrigeration device 6 is transmitted to the interior of the test and detection box 1 through the cold air pipe 61. At the same time, the setting of the air outlet pipe 62 facilitates the dissipation of hot air through the air outlet pipe 62, which is convenient for quickly cooling the interior of the test and detection box 1, and is beneficial to the accuracy of the result of the next test.

[0032] An abutment rod 22 is welded to the inner side of the partition 2. The bottom of the test detection box 1 is rotatably connected to the third transmission screw 11 through a bearing. The third transmission screw 11 is connected to the partition 2 by internal and external threads. A third motor is installed at one end of the third transmission screw 11. The third transmission screw 11 rotates when the third motor is started, thereby driving the partition 2 to move left and right, which is convenient for subsequent adjustment of the position of the fiber tube.

[0033] One side of the test detection box 1 is provided with an opening and closing component that is easy to adjust. The opening and closing component includes a fixed cylinder 7, and a mounting block 71 is fixed at the end opening of the fixed cylinder 7. The mounting block 71 is fixed to the fixed cylinder 7 by screws. A top block 72 is slidably inserted on the mounting block 71. A first air bag 73 is bonded between the top block 72 and the fixed cylinder 7. The abutment rod 22 and the top block 72 are correspondingly arranged. When the abutment rod 22 squeezes the top block 72, the top block 72 is pressed and accommodated in the interior of the fixed cylinder 7, and then the top block 72 squeezes the first air bag 73 for compression.

[0034] The test and detection box 1 is provided with receiving grooves at the openings of the cold air pipe 61 and the air outlet pipe 62, and a second airbag 74 is bonded in the receiving grooves. The volume of the first airbag 73 is larger than that of the second airbag 74. A connecting pipe 75 is connected between the second airbag 74 and the first airbag 73. A pulling block 76 is bonded to one end of the second airbag 74, and a sealing block 77 is welded to one end of the pulling block 76. The two sealing blocks 77 are respectively arranged corresponding to the openings of the cold air pipe 61 and the air outlet pipe 62.

[0035] When the top block 72 squeezes the first airbag 73 and compresses it, the gas therein is transmitted to the two second airbags 74 through the connecting tube 75 respectively. The two second airbags 74 expand and then squeeze the pulling block 76 and the sealing block 77, so that the openings of the cold air pipe 61 and the outlet pipe 62 are opened, which is convenient for the passage of cold air and heat dissipation. A return spring 78 is fixedly connected between the sealing block 77 and the accommodating groove. The setting of the return spring 78 provides elastic force for the two sealing blocks 77 to close the openings of the cold air pipe 61 and the outlet pipe 62 respectively.

[0036] In actual use, the fiber tube is inserted into the through hole 21 on the partition 2, and the first transmission screw 51 is rotated by starting the first motor, thereby driving the first connecting blocks 52 on both sides to approach or move away from each other, so that the first clamping block 53 clamps the fiber tube at the same time, and the second transmission screw 5 is rotated by starting the second motor, thereby driving the second connecting blocks 56 on both sides to approach or move away from each other, so that the second clamping block 57 clamps the fiber tube at the same time, and the second clamping block 57 and the first clamping block 53 are staggered and overlapped to form a relatively sealed structure of the through hole on the partition 2, and it is also suitable for clamping and fixing fiber tubes of various diameters. By turning on the ignition control switch, the gas in the fuel storage tank 3 is ignited and sprayed out through the ventilation pipe 31 and the flamethrower 41, thereby performing refractory fiber treatment on the fiber tube. After the test is performed, the third transmission screw 11 is rotated by starting the third motor, thereby driving the partition 2 to move left and right, so as to facilitate the subsequent adjustment of the position of the fiber tube. When the abutment rod 22 squeezes the top block 72, the top block 72 is pressurized and accommodated in the interior of the fixed tube 7, and then the top block 72 squeezes the first air bag 73 for compression. At this time, the gas therein is transmitted to the two second air bags 74 respectively through the connecting pipe 75. The two second air bags 74 expand and then squeeze the pulling block 76 and the sealing block 77, so that the openings of the cold air pipe 61 and the air outlet pipe 62 are opened, and the cold air in the refrigeration device 6 is transmitted to the interior of the test and detection box 1 through the cold air pipe 61. At the same time, the air outlet pipe 62 facilitates the dissipation of hot air through the air outlet pipe 62, which is convenient for quickly cooling the interior of the test and detection box 1, and is beneficial to the accuracy of the result of the next test.
