Description

Technical Field

[0001] The present invention relates to the technical field of heating equipment, and in particular to a heat insulation detection heating device and an auxiliary temperature control method. Background Art

[0002] The test bench currently used for thermal insulation testing is equipped with a heating device. During the thermal insulation testing process, the aerogel board to be tested is placed on the upper end of the heating plate of the heating device, and the end surface of one side of the aerogel board is heated to a higher temperature. The thermal insulation performance of the aerogel board is tested by testing the temperature of the end surface of the other side of the aerogel board. In addition, during the testing process, it is necessary to press the end surface of one side to test its thermal insulation performance under different pressures. According to different pressing pressures, the test temperature is recorded in real time. Therefore, the entire testing process is relatively long, resulting in the temperature fluctuation of the heated surface of the aerogel board. When the temperature is too high, there is a lack of effective cooling means, which affects the detection accuracy. Summary of the Invention

The base is slidably connected to a main rod, which can slide up and down along the inner wall of the base. The main rod is provided with a third channel and a fourth channel. The upper end of the third channel is connected to the fourth channel. When the main rod slides upward, it can be inserted into the countersunk portion to connect the fourth channel with the countersunk portion.

[0006] The base is further provided with a second through hole portion, which is located radially outside the countersunk portion. One end of the second through hole portion is connected to the radial outer end of the countersunk portion, and the other end can be connected to the outside.

[0007] Furthermore, when the main rod is inserted upward into the countersunk portion, the upper portion of the main rod is located radially inside the extension portion with the smallest diameter, and when the main rod slides downward out of the countersunk portion, the fourth channel is disconnected from the countersunk portion.

[0008] Furthermore, a cover plate is installed on the top of the main rod, the cover plate closes the upper end of the third channel, and the fourth channel is located below the cover plate.

[0009] Furthermore, a second driving component is connected to the bottom of the main rod, and the second driving component drives the main rod to move up and down. An air pipe is installed at the lower part of the main rod, one end of the air pipe is connected to the third channel, and the other end is connected to the air source.

[0014] The present invention also discloses an auxiliary temperature control method for a thermal insulation detection and heating device. The thermal insulation detection and heating device is used for temperature control. The base is further provided with a first through-hole portion, one end of the first through-hole portion is connected to the second through-hole portion, and the other end is connected to the outside. The base is installed with an elastic component, and the elastic component includes a slider. The slider is provided with a first channel and a second channel. The first channel is connected to the counterbore portion, and the bottom of the second channel is connected to the first channel. The specific temperature control steps are as follows:

[0015] ① The main rod moves upward, the fourth channel is connected to the countersunk part, and air is introduced into the third channel. The air flows into the countersunk part through the third and fourth channels, and flows along the first and second channels. The air pressure in the countersunk part gradually increases;

[0016] ② The airflow in the counterbore portion pushes the slider to move radially outward along the base, so that the second channel is connected to the first through-hole portion, thereby forming a connected heat dissipation channel between the first through-hole portion, the second channel, the first channel, the second through-hole portion, and the counterbore portion;

[0017] ③ The main rod moves downward, the fourth channel is disconnected from the countersunk portion, and the air pressure in the countersunk portion gradually decreases, causing the slider to move radially inward along the base, and the second channel is disconnected from the first through-hole portion.

[0018] Beneficial effects of the present invention:

[0019] 1. In the process of air flowing gradually from the radial inner side to the outer side of the extension part, since the first channels of the two adjacent extension parts are staggered 90 degrees in the circumferential direction, when the air flows between different first channels and second channels and flows from the radial inner side of the extension part 71 to the radial outermost side, the air flow is blocked multiple times and the flow direction is changed, so that the air can fully contact each position of the bottom surface of the disc body of the heating plate main body at different positions, thereby generating more sufficient heat exchange and improving the cooling efficiency.

[0020] 2. Since the slider moves radially outward along the base under the action of air pressure, the air pressure in the countersunk part needs to be increased to form a heat dissipation channel. The way to increase the air pressure is to continuously introduce gas into the countersunk part, which increases the number of gas molecules in the countersunk part. The heat exchange efficiency between the gas molecules and the heating plate body is higher, thereby improving the cooling efficiency.

[0021] 3. From the time when the main body of the heating plate falls back to the specified insulation temperature to the time when the second channel is disconnected from the first through-hole portion, a seal is formed in the countersunk portion. The response time of the entire process is short, which prevents the main body temperature of the heating plate from dropping too much within the response time, and is conducive to stabilizing the detection temperature required by the main body of the heating plate.

DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in this embodiment with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0030] like Figure 1 As shown, a heat insulation detection and heating device includes a bracket body assembly 1, which includes a base plate 13 located at the bottom, with a column 12 fixedly installed on the upper end of the base plate 13. The column 12 is a cylindrical long strip structure, and the column 12 extends vertically upward along the upper end surface of the base plate 13. The columns 12 are distributed on both sides of the base plate 13. A crossbeam 11 is fixedly installed on the top of the column 12, and the crossbeam 11 connects the columns 12 on both sides. A pressure plate assembly 4 is slidably connected to the column 12 and installed. The pressure plate assembly 4 includes a bushing 43. The bushing 43 is inserted into the column 12 and can move up and down along the outer wall of the column 12. A slide plate 41 is fixedly installed between the bushings 43 on both sides. A pressure plate 42 is installed below the center of the slide plate 41, and a temperature sensor is installed on the bottom surface of the pressure plate 42.

[0031] like Figure 1 As shown, a first driving component 2 is installed at the upper end of the crossbeam plate 11. The first driving component 2 is an electric cylinder. The output end of the first driving component 2 passes downward through the crossbeam plate 11 and a pressure sensor 3 is connected to the bottom of the output end. The lower end of the pressure sensor 3 is fixedly connected to the slide plate 41. Driven by the first driving component 2, the pressure plate assembly 4 moves up and down as a whole.

[0032] The upper end of the bottom plate 13 is fixedly mounted with a base 5, and the upper end of the base 5 is fixedly mounted with a heating plate body 7. The heating plate body 7 is connected to an external electric heating system to control the heating temperature. The heating plate body 7 is made of alloy. The upper end of the heating plate body 7 is used to place a detection plate 8. The detection plate 8 is aerogel, which is a heat-insulating material. The detection plate 8 is a rectangular plate-shaped structure. The bottom surface of the detection plate 8 is in contact with the upper end surface of the heating plate body 7. By energizing the heating plate body 7 to generate high temperature, the bottom surface of the detection plate 8 in contact with it is heated. When the bottom surface reaches the specified temperature, the pressing plate 42 moves downward and the bottom surface of the pressing plate 42 presses the top surface of the detection plate 8. The pressing plate 4 2 The temperature sensor on the bottom detects the temperature of the top surface of the detection plate 8 and feeds it back to the system to detect the temperature of the top surface of the detection plate 8. During the detection process, the bottom surface of the detection plate 8 needs to be kept warm (the insulation temperature is set between 500 degrees and 800 degrees according to actual needs), and the insulation time is 10 minutes to 30 minutes. During this process, the first driving component 2 drives the control plate 42 downward. Since the detection plate 8 is made of soft material, the pressure plate 42 presses the detection plate 8 downward. The temperature sensor on the bottom surface of the pressure plate 42 feeds back the temperature of the top surface of the detection plate 8 under different squeezing degrees to the system to comprehensively detect the thermal insulation performance of the detection plate 8.

[0033] like Figure 1 、 Figure 2 As shown, the heating plate body 7 includes a disc body at the top and an extension portion 71 at the bottom. The disc body of the heating plate body 7 is the heating body, and the extension portion 71 extends downward along the bottom surface of the disc body of the heating plate body 7 to form a bulge. Figure 3 As shown, the extension portion 71 is an annular surrounding structure. The extension portions 71 are evenly spaced along the radial direction of the heating plate body 7. The diameter of the extension portion 71 gradually increases radially outward along the heating plate body 7. The outer diameter of the top disk is larger than the outer diameter of the outermost extension portion 71. A second channel 72 is formed between two adjacent extension portions 71. The second channel 72 is an annular channel. The extension portion 71 is provided with a first channel 711. The first channel 711 radially penetrates the extension portion 71. Two first channels 711 are symmetrically provided along the axis of the extension portion 71. The first channel 711 divides the extension portion 71 into two circular arc-shaped semi-rings. The first channel 711 is connected to the adjacent second channel 72. The first channels 711 of the two adjacent extension portions 71 are staggered 90 degrees from each other in the circumferential direction.

[0034] like Figure 1 、 Figure 2 As shown, the disc body on the top of the base 5 is fixedly connected to the base 5 by screws. A countersunk portion 51 is provided at the upper end of the base 5, and the extension portion 71 is inserted into the countersunk portion 51. The diameter of the maximum diameter extension portion 71 is smaller than the inner diameter of the countersunk portion 51. A gap is left between the outer wall of the extension portion 71 located at the radially outermost end (i.e., the maximum diameter extension portion 71) and the circumferential inner wall of the countersunk portion 51 for air circulation.

[0035] Combine Figure 2 、 Figure 3 After the extension portion 71 is inserted into the counterbore portion 51 , the bottom surface of the extension portion 71 abuts against the inner wall of the bottom of the counterbore portion 51 , and at this time, the second channel 72 falls into the range of the counterbore portion 51 .

[0036] like Figure 1 As shown, a ventilation assembly 9 is installed at the upper end of the base plate 13. Specifically, the ventilation assembly 9 includes a main rod 91, which is inserted upward into the bottom of the base 5. The main rod 91 is slidably connected to the base 5. The main rod 91 can slide up and down along the inner wall of the base 5. A second driving component 92 is connected to the bottom of the main rod 91. The second driving component 92 is a cylinder. The second driving component 92 is fixedly installed at the upper end of the base plate 13. The second driving component 92 can drive the main rod 91 to move up and down.

[0037] like Figure 4 、 Figure 6 As shown, the main rod 91 is provided with a third hole 911 and a fourth hole 912. The third hole 911 is arranged axially along the main rod 91. The upper end of the third hole 911 passes through the top of the main rod 91 and extends downward. The arrangement of the third hole 911 forms a cylindrical structure on the upper portion of the main rod 91. The fourth hole 912 penetrates the inner wall of the cylindrical structure along the radial direction of the main rod 91. Four fourth holes 912 are provided, and the upper ends of the fourth holes 912 pass through the top of the main rod 91. The third hole 911 and the fourth hole 912 are connected to each other.

[0038] A cover plate 913 is installed on the top of the main rod 91, and the cover plate 913 closes the upper end of the main rod 91, so that the top of the third channel 911 and the top of the fourth channel 912 are both closed, forming a flow channel from the third channel 911 to the fourth channel 912 in the main rod 91.

[0039] like Figure 4 As shown, an air pipe 93 is installed at the lower part of the main rod 91, one end of the air pipe 93 is connected to the third channel 911, and the other end is connected to the air source.

[0040] like Figure 1 As shown, when the main rod 91 is disconnected, the main rod 91 is at the lower end limit position. At this time, the cover plate 913 is located below the countersunk portion 51, and the fourth channel 912 is blocked by the inner wall of the base 5, so that gas cannot flow from the fourth channel 912 into the countersunk portion 51.

[0041] like Figure 6 As shown, the main rod 91 slides upward and is inserted into the counterbore portion 51, so that the fourth channel 912 is at least partially located in the counterbore portion 51, thereby connecting the fourth channel 912 with the counterbore portion 51. Specifically, the upper portion of the main rod 91 is inserted into the inner side of the extension portion 71 with the smallest diameter. The outer diameter of the main rod 91 is smaller than the diameter of the extension portion 71 with the smallest diameter. A flow channel is formed between the outer wall of the main rod 91 and the inner wall of the extension portion 71 with the smallest diameter. Figure 3After air enters the air pipe 93 , the air can flow into the counterbore portion 51 through the third hole 911 and the fourth hole 912 , and circulate along the first channel 711 and the second channel 72 .

[0042] like Figure 1 、 Figure 2 As shown, the base 5 is also provided with a second through hole portion 53, and the second through hole portion 53 is arranged radially along the base 5, and the second through hole portion 53 is located radially outside the countersunk portion 51. One end of the second through hole portion 53 is connected to the radial outer end of the countersunk portion 51, and the other end can be connected to the outside world. One end of the second through hole portion 53 is connected to the countersunk portion 51, and the other end passes through the outer wall of the base 5 and is connected to the outside world. After the air pipe 93 takes in air, the air flow can flow into the countersunk portion 51 through the third channel 911 and the fourth channel 912, and flow along the first channel 711 and the second channel 72, and finally flow out from the second through hole portion 53, forming a cooling air flow channel. When the temperature of the heating plate body 7 is higher than the maintenance temperature required for the specified detection after heating, the air pipe 93 takes in air to cool down, so that the heat at the lower end of the heating plate body 7 is taken away by the air, achieving a cooling effect, and combined with Figure 1 、 Figure 3 The air gradually flows from the radial inner side of the extension part 71 to the outer side. Since the first channels 711 of the two adjacent extension parts 71 are staggered 90 degrees in the circumferential direction, when the air flows between different first channels 711 and second channels 72 and flows from the radial inner side of the extension part 71 to the radial outermost side, the air flow is blocked multiple times and the flow direction is changed, so that the air can fully contact each position of the bottom surface of the disc body of the heating plate main body 7 at different positions, thereby generating more sufficient heat exchange and improving the cooling efficiency.

[0043] like Figure 1 、 Figure 2 As shown, the base 5 is mounted with an elastic assembly 6, which includes a slider 63. The slider 63 is inserted into the second through-hole portion 53 and is capable of axial movement along the second through-hole portion 53. The elastic assembly 6 also includes a limiting sleeve 61 and a spring 62. The limiting sleeve 61 is located at the radially outer end of the second through-hole portion 53 along the base 5 and is fixedly connected to the base 5. The spring 62 is partially located within the second through-hole portion 53, with one end of the spring 62 abutting the limiting sleeve 61 and the other end abutting the slider 63.

[0044] like Figure 2 As shown, the base 5 is also provided with a first through hole portion 52, which extends downward along the upper end of the base 5, the bottom of the first through hole portion 52 is connected to the second through hole portion 53, the upper end of the first through hole portion 52 is connected to the outside world, and the first through hole portion 52 can be connected to the countersunk portion 51 through the second through hole portion 53.

[0045] like Figure 2As shown, the movement of the slider 63 can connect or disconnect the first through-hole portion 52 with the counterbore portion 51. Specifically, the slider 63 is provided with a first hole 631 and a second hole 632. The first hole 631 is arranged along the axial direction of the slider 63 and passes through the end surface of the slider 63 on the side close to the counterbore portion 51. The second hole 632 is arranged along the radial direction of the slider 63. The lower end of the second hole 632 is connected to the first hole 631, and the upper end of the second hole 632 passes through the radial inner wall of the slider 63.

[0046] like Figure 2 As shown, when the slider 63 moves, the first channel 631 is directly connected to the counterbore portion 51 or is connected to the counterbore portion 51 through the second through hole portion 53 .

[0047] like Figure 2 As shown, when there is no ventilation in the third channel 911, the slider 63 moves to the radial inner side of the base 5 under the left and right sides of the spring 62. At this time, the second channel 632 is disconnected from the first through hole portion 52, and a closed cavity is formed in the countersunk portion 51, which is beneficial to the insulation of the heating plate body 7.

[0048] like Figure 4 、 Figure 5 As shown, when the third channel 911 is ventilated, the air flows to the slider 63 through the countersunk portion 51. When the air pressure in the countersunk portion 51 increases, the slider 63 moves radially outward along the base 5 under the action of the air pressure, so that the second channel 632 can move to the bottom of the first through-hole portion 52 and form a connection with the first through-hole portion 52, so that a connected heat dissipation channel is formed among the first through-hole portion 52, the second channel 632, the first channel 631, the second through-hole portion 53, and the countersunk portion 51, so as to discharge the hot air in the countersunk portion 51, thereby achieving a cooling effect on the heating plate body 7.

[0049] Since the slider 63 moves radially outward along the base 5 under the action of air pressure, the air pressure in the countersunk portion 51 needs to be increased to form a heat dissipation channel. The way to increase the air pressure is to continuously introduce gas into the countersunk portion 51, which increases the number of gas molecules in the countersunk portion 51, and the heat exchange efficiency between the gas molecules and the heating plate body 7 is higher, thereby improving the cooling efficiency.

[0050] Once the heating plate body 7 returns to the designated holding temperature, ventilation in the third channel 911 stops, and the main rod 91 descends, disconnecting the fourth channel 912 from the countersunk portion 51. The air pressure in the countersunk portion 51 gradually decreases, causing the slider 63 to move radially inward along the base 5, disconnecting the second channel 632 from the first through-hole portion 52. From the time the heating plate body 7 returns to the designated holding temperature until the second channel 632 is disconnected from the first through-hole portion 52, and a seal is formed in the countersunk portion 51, the entire process has a short response time, preventing the temperature of the heating plate body 7 from dropping too much within the response time, which is conducive to stabilizing the required detection temperature of the heating plate body 7.

[0051] An auxiliary temperature control method for a thermal insulation detection and heating device, using the thermal insulation detection and heating device, specifically comprising the following steps:

[0052] ① Such as Figure 1 、 Figure 2 As shown, in the initial state, the main rod 91 is located at the lower end limit position, the cover plate 913 is located below the countersunk portion 51, the fourth channel 912 is closed by the inner wall of the base 5, so that the fourth channel 912 cannot be connected with the countersunk portion 51, and the third channel 911 is in an unventilated state. The slider 63 is located at the innermost position along the radial direction of the base 5 under the action of the spring 62, and the second channel 632 is disconnected from the first through hole portion 52, so that the slider 63 disconnects the first through hole portion 52 from the countersunk portion 51.

[0053] Driven by the second drive member 92, the main rod 91 moves upward, and the upper end of the main rod 91 is inserted radially inward of the smallest diameter extension portion 71, thereby establishing communication between the fourth channel 912 and the counterbore portion 51. Simultaneously, air is introduced into the third channel 911 through the air pipe 93. The air flows through the third and fourth channels 911, 912, into the counterbore portion 51, and then along the first and second channels 711, 72, gradually increasing the air pressure within the counterbore portion 51. As the air pressure within the counterbore portion 51 gradually increases, the number of gas molecules within the counterbore portion 51 increases, allowing for more efficient heat exchange between the gas molecules and the heating plate body 7.

[0054] ② The airflow in the counterbore portion 51 pushes the slider 63 to move radially outward along the base 5, so that the second channel 632 is connected to the first through-hole portion 52, thereby forming a connected heat dissipation channel between the first through-hole portion 52, the second channel 632, the first channel 631, the second through-hole portion 53, and the counterbore portion 51. The air flows gradually from the radial inner side of the extension portion 71 to the outer side. Since the first channels 711 of the two adjacent extension portions 71 are staggered 90 degrees in the circumferential direction, the air flow is blocked multiple times and the flow direction is changed when it flows between different first channels 711 and second channels 72 and flows from the radial inner side of the extension portion 71 to the radial outermost side. This allows the air to fully contact each position of the bottom surface of the disc body of the heating plate body 7 at different positions, thereby generating more sufficient heat exchange and improving the cooling efficiency.

[0055] ③ When the heating plate body 7 drops back to the specified temperature, the main rod 91 moves downward under the drive of the second driving component 92, and the main rod 91 moves downward to the bottom of the countersunk portion 51, and the fourth channel 912 is disconnected from the countersunk portion 51. At this time, the air pressure in the countersunk portion 51 gradually decreases, causing the slider 63 to gradually move radially inward along the base 5 until the second channel 632 is disconnected from the first through hole portion 52, thereby disconnecting the first through hole portion 52 from the countersunk portion 51.

[0056] When the air pressure in the countersunk portion 51 is insufficient, the slider 63 moves and immediately disconnects the first through-hole portion 52 from the countersunk portion 51, forming a seal inside the countersunk portion 51. The response time of the entire process is short, which prevents the temperature of the heating plate main body 7 from dropping too much within the response time, and is conducive to stabilizing the detection temperature required by the heating plate main body 7.

[0057] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
