Description

Technical Field

[0001] The present invention relates to the technical field of quartz pipe fitting detection, and particularly to a detection device for bubbles and gas lines in a hot-worked quartz expanded pipe. Background Art

[0002] During the production of hot-worked pipe fittings, the presence of bubbles and gas lines seriously affects the product quality. There are residual stresses inside the pipe fittings after hot working, and the stress release during the cooling process will cause changes in the bubble morphology (such as migration, coalescence, or rupture). If the detection is too early (before complete cooling), the bubble position and size may not be stable, resulting in distorted detection results. Moreover, the existing detection devices are difficult to effectively control the temperature of the pipe fittings during the detection process and cannot meet the requirements of temperature stability for bubble detection, further exacerbating the detection error.

[0008] Preferably, the promoting device further includes a motor fixed outside the housing. Two gears are fixed to the output end of the motor, and gear sleeves meshing with the gears are provided on both metal sleeves.

[0009] Preferably, a scraping sleeve is installed at the output end of the motor. The scraping sleeve contacts the filter cover. Water receiving frames located in the transition area are fixedly installed on both sides of the housing. The scraping sleeve is located above the water receiving frames, and the water receiving frames are communicated with a water accumulation tank.

[0010] Preferably, both the spiral cooling pipe and the filter cover are made of stainless steel materials. The mesh inner liner is woven from ceramic fiber materials.

The electric cylinder is fixed with a push rod, and the push rod contacts the wall of the pipe fitting.

[0012] Preferably, the auxiliary frame body includes two symmetrically arranged stable cross bars. A number of auxiliary wheels are equidistantly distributed on the stable cross bars.

[0014] Compared with the existing technology, the beneficial effects of the present invention are as follows: 1. The temperature control device of the present invention has a setting of three temperature zones. There are obvious gradients in different temperature zones. The temperature in the high-temperature zone is the highest, followed by the transition zone, and the lowest in the low-temperature zone. The high temperature in the high-temperature zone makes water easier to evaporate, generating a large amount of water vapor and carrying energy. The temperature in the transition zone can ensure that the water vapor reacts with the water-absorbing salts to further lower the temperature, and the remaining water vapor can effectively promote the cooling of the ice-salt mixture. Through the synergistic effect of the temperature gradients in the three temperature zones, the orderly transfer and efficient utilization of heat are realized, ensuring that the quartz diffusion tube can be gradually cooled to the temperature required for detection at different stages. This step-by-step cooling method greatly improves the cooling efficiency. After quickly reducing the temperature of the pipe fitting from the initial high temperature by a certain amount in the high-temperature zone, the transition zone can receive the heat transferred from the high-temperature zone and continue to cool, avoiding damage to the pipe fitting caused by sudden temperature changes, and at the same time accelerating the overall cooling process, enabling the pipe fitting to reach a stable detection temperature in a short time.

[0015] 2. After hot processing, there are residual stresses inside the pipe fittings. The temperature gradient synergistically helps the stresses to be released stably. The temperature change rates in different temperature zones are different, enabling the internal stresses of the pipe fittings to be gradually and evenly released during the cooling process, preventing the change of the bubble shape caused by stress concentration, and providing a stable internal environment for accurately detecting the bubble gas line.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0019] Refer to the attached Figures 1 - 6A device for detecting air bubbles and gas lines in hot-processed quartz expansion tubes, comprising a temperature control device and a detection mechanism installed on a workbench 1, wherein the temperature control device comprises a shell 100, wherein the shell 100 is divided into a high temperature zone 2, a transition zone 3 and a low temperature zone 4 in sequence along the moving direction of the tube, and an auxiliary frame 8 for supporting the moving of the tube is provided through the three zones; The high temperature zone 2, the transition zone 3 and the low temperature zone 4 respectively include a spiral cooling pipe 21, a filter cover 31 and a cylinder 41 fixed in the housing 100. The spiral cooling pipe 21 includes an air delivery pipe 200, which is connected to the filter cover 31 and the cylinder 41 respectively. A mesh inner liner 32 is disposed in the filter cover 31 , and water-absorbent salts are attached to the mesh inner liner 32 . The cylinder body 41 includes an inner cavity 42 , and an ice-salt mixture is injected into the inner cavity 42 .

[0020] The temperature control device is divided into high temperature zone 2, transition zone 3 and low temperature zone 4, forming a three-zone gradient cooling method. The pipe fittings pass through high temperature zone 2, transition zone 3 and low temperature zone 4 in turn to achieve segmented gradient cooling of the pipe fittings. The cooling rates in different temperature zones are controlled to produce gradient stress release in the axial direction of the pipe fittings, effectively reducing morphological changes such as bubble migration and merging caused by concentrated stress.

[0021] Specifically, in the high temperature zone 2, cold water is input into the spiral cooling tube 21, and the pipe after heat treatment comes into contact with the spiral cooling tube 21, which quickly releases heat, vaporizes the cold water, and cools it quickly. In this way, the outer shell of the pipe is first stabilized, and as the temperature gradually decreases, the internal stress is evenly released, ensuring that the bubbles maintain their original shape during the cooling process, providing a basis for subsequent accurate detection; The pipes in the high temperature area are cooled down rapidly by the cooling water. Then, part of the cooling water absorbs a large amount of heat and vaporizes into water vapor. The water vapor is transported to the transition area 3 in an orderly manner through the gas pipe 200. The water vapor is fully in contact with the mesh liner 32 filled with water-absorbing salts. The water-absorbing salts react with the water vapor to form a hydration endothermic reaction, which reduces the temperature. Therefore, the pipes passing there will be cooled down again. When the pipe moves into the low temperature zone 4, a part of the water vapor will enter the inner cavity 42. Since the inner cavity 42 contains the ice-salt mixture, its temperature is relatively low. As the water vapor enters the low temperature zone, the heat it carries will promote the melting of ice in the ice-salt mixture. This is an endothermic process, which will further participate in the cooling process of the low temperature zone. By the above method, there is an obvious temperature gradient in the three temperature zones. The temperature in the high-temperature zone is the highest, followed by the transition zone, and the lowest in the low-temperature zone. The high temperature in the high-temperature zone makes it easier for water to evaporate, generating a large amount of water vapor and carrying energy. The temperature in the transition zone can ensure the hydration reaction between water vapor and salts, further reducing the temperature, and the remaining water vapor can effectively promote the cooling of the ice-salt mixture. Through the synergistic effect of the temperature gradient in the three temperature zones, the orderly transfer and efficient utilization of heat are achieved, ensuring that the quartz diffusion tube can gradually cool down to the temperature required for detection at different stages.

[0022] Compared with a single cooling method, this step-by-step cooling method greatly improves the cooling efficiency. After quickly reducing the temperature of the pipe fittings from the initial high temperature in the high-temperature zone by a certain amount, the transition zone can receive the heat transferred from the high-temperature zone and continue to cool down, avoiding damage to the pipe fittings caused by sudden temperature changes. At the same time, it speeds up the overall cooling process, enabling the pipe fittings to reach a stable detection temperature in a shorter time.

[0023] Moreover, there are residual stresses inside the pipe fittings after hot processing. The temperature gradient synergy helps the stress to be released stably. The temperature change rates in different temperature zones are different, enabling the internal stress of the pipe fittings to be gradually and evenly released during the cooling process, preventing the change of bubble morphology caused by stress concentration, and providing a stable internal environment for accurately detecting the bubble gas line. Specifically, the rapid cooling in the high-temperature zone initially stabilizes the outer layer of the pipe fittings, and the continuous cooling in the transition zone and the low-temperature zone further releases the internal stress, avoiding situations such as bubble migration and merging caused by stress mutation, and improving the accuracy of the detection results.

[0024] Reference Figures 1 - 3 , a refrigerating water tank 25 fixed on the operating table 1 is arranged below the high-temperature zone 2. The spiral cooling pipe 21 is respectively provided with a water inlet 23 and a water outlet 24, and the water inlet 23 and the water outlet 24 are respectively communicated with the water inlet end and the water outlet end of the refrigerating water tank 25; Thus, a circulating water structure in the spiral cooling pipe 21 is formed. Cold water is input into the spiral cooling pipe 21 through the refrigerating water tank 25 and finally flows back into the refrigerating water tank 25 for refrigeration again, which can ensure that the spiral cooling pipe 21 is always in a state of cold water circulation, enabling the spiral cooling pipe 21 to continuously cool down; A gas collecting box 22 is fixed above the spiral cooling pipe 21, an aeration box 34 is fixed above the filter cover 31, and the gas transmission pipe 200 is respectively communicated with the gas collecting box 22 and the inner cavity 42, and a flowmeter and a regulating valve are provided at the communicating place. The cylinder body 41 is provided with an exhaust port 43 and a feeding port 44; The steam generated by the spiral cooling pipe 21 when heated will rise into the gas collecting box 22. Subsequently, the gas collecting box 22 will input the water vapor into the aeration box 34 and the inner cavity 42 through the gas transmission pipe 200 for corresponding reactions. During this period, the output volume of the steam can be adjusted intensively through the flowmeter and the regulating valve to ensure the sufficiency of the reaction. And after the water vapor enters the inner cavity 42, water vapor will be generated, which can be discharged through the exhaust port 43 recently.

[0025] Reference Figure 2 and Figure 3 On both sides of the net-shaped inner liner 32, metal sleeves 33 are fixedly installed. The metal sleeves 33 are located outside the filter cover 31. In the transition area 3, a promoting device 10 is provided. The promoting device 10 includes mounting rings 800 arranged on both sides of the metal sleeve 33. The mounting rings 800 are fixed on the housing 100. The metal sleeve 33 and the mounting rings 800 are slidably connected. The promoting device 10 further includes a motor 400 fixed outside the housing 100. Two gears 500 are fixed to the output end of the motor 400. Gear sleeves 700 meshing with the gears 500 are provided on both metal sleeves 33. A scraping sleeve 600 is installed at the output end of the motor 400. The scraping sleeve 600 contacts the filter cover 31. Water receiving frames 35 located in the transition area 3 are fixedly installed on both sides of the housing 100. The scraping sleeve 600 is located above the water receiving frames 35. The water receiving frames 35 communicate with a water storage tank 36; The water-absorbing salts attached to the net-shaped inner liner 32 need to be in deep contact with the water vapor to fully react. By starting the motor 400, the gears 500 can be driven to rotate, so that the gear sleeves 700 meshing with the gears 500 rotate, and the metal sleeve 33 rotates, thereby driving the net-shaped inner liner 32 to rotate. The rotating net-shaped inner liner 32 can receive the water vapor discharged from the upper aeration box 34 without dead angles. After the water vapor reacts with the water-absorbing salts, hydrates will be generated and attached to the filter cover 31. The rotating scraping sleeve 600 can scrape it off, making it fall into the water receiving frame 35 and finally discharged from the water storage tank 36.

[0026] In this embodiment, the spiral cooling pipe 21 and the filter cover 31 are both made of stainless steel materials. The net-shaped inner liner 32 is woven from ceramic fiber materials. The water-absorbing salts attached to the net-shaped inner liner 32 are specifically calcium chloride. The ice-salt mixture injected into the inner cavity 42 is specifically a mixture of ice and sodium chloride. Between the adjacent high-temperature area 2, transition area 3 and low-temperature area 4, a barrier element 300 and a position sensor fixed on the housing 100 are provided.

[0027] In addition, reference Figure 4 On one side of the workbench 1, a feeding component 6 is provided. The feeding component 6 includes a crossbar frame 61 for placing pipe fittings, and also includes an electric cylinder 62. The electric cylinder 62 is fixed with a push rod 63, and the push rod 63 contacts the pipe fitting wall; Reference Figure 2, the auxiliary frame 8 includes two stable crossbars 81 symmetrically arranged. A number of auxiliary wheels 82 are equidistantly distributed on the stable crossbars 81. A number of springs 83 are fixed between the two stable crossbars 81. The inner diameters of the spiral cooling pipe 21, the filter cover 31, and the cylinder body 41 are the same. The auxiliary wheels 82 are in contact with the transverse symmetry axes of the spiral cooling pipe 21, the filter cover 31, and the cylinder body 41; During operation, the pipe fittings to be detected are placed on the crossbar frame 61. Subsequently, the electric cylinder 62 is started to push the push rod 63 forward, so that the push rod 63 can push the pipe fitting wall to move forward within the crossbar frame 61. Subsequently, continuous advancement will cause it to enter the housing 100. After the pipe fitting enters the housing 100, its wall will squeeze the auxiliary wheels 82 of the auxiliary frame 8, causing the auxiliary wheels 82 to enter the pipe fitting. At this time, the spring 83 will contract, and the pipe fitting will be lifted by the auxiliary frame 8. The auxiliary wheels 82 will rotate when the pipe fitting moves, ensuring the smooth advancement of the pipe fitting.

[0028] Reference Figure 5 and Figure 6 , the detection mechanism includes a detection frame 5 fixed on the workbench 1. An electric slide 51 is installed on the detection frame 5. A motor 400 is installed on the electric slide 51. A detection chamber 9 and a material receiving assembly 7 are provided below the motor 400. The detection chamber 9 includes two transparent housings 91 symmetrically arranged. The transparent housings 91 are installed on electric push rods 92. The material receiving assembly 7 includes an electric turntable 71. The electric turntable 71 is installed with a material receiving rod frame 72 located within the two transparent housings 91. A heat preservation head 93 is installed on the material receiving rod frame 72. The transparent housing 91 is provided with a vacuum cavity 94. Heat preservation grooves 95 and heat preservation plugs 96 are respectively provided at the docking ends of the two transparent housings 91.

[0029] After the pipe fitting finishes cooling, it will be pushed out of the housing 100. The material receiving rod frame 72 will relatively enter the processed quartz and lift it up. Subsequently, after the pipe fitting moves between the two transparent housings 91, the two transparent housings 91 are docked by starting the electric push rod 92. The heat preservation plug 96 will enter the heat preservation groove 95. The detection chamber 9 can ensure that the pipe fitting will not cool down during detection. Subsequently, the pipe fitting in the detection chamber 9 is detected by the motor 400. The position of the motor 400 can be moved through the electric slide 51. After the detection is completed, the transparent housing 91 is opened, and the electric turntable 71 is started to drive the material receiving rod frame 72 to rotate, so that the pipe fitting after detection is moved out of the workbench 1.

[0030] The working process of the present invention: First, the pipe fittings to be detected are pushed into the housing 100 through the feeding assembly 6. Subsequently, the pipe fittings move on the auxiliary frame 8. During this period, the pipe fittings move successively in the middle, and cooling is carried out during the movement. After cooling, the pipe fittings move to the end of the auxiliary frame 8. The pipe fittings will move onto the material receiving assembly 7 and enter the detection chamber 9. Subsequently, detection is carried out through the detection mechanism.
