Description

Technical Field

[0001] The present invention relates to the technical field of condenser detection, in particular to an inner cavity pressure-bearing and anti-leakage detection device for condenser production. Background Art

[0002] The condenser needs to withstand a certain amount of pressure during operation. If the pressure bearing capacity of the inner cavity is insufficient, it may cause serious safety accidents such as equipment rupture and leakage. Through pressure testing, potential safety hazards can be discovered in time to ensure that the condenser operates safely under normal working pressure. The condenser is an important equipment in many industrial production processes. If a failure occurs due to pressure problems, it will cause production interruption and bring huge economic losses to the company. In the refrigeration system, the shell and tube condenser is one of the key components. If the shell and tube condenser has a pressure problem, it may cause refrigerant leakage, affect the refrigeration effect, and even damage the entire refrigeration system. Pressure testing can ensure the normal operation of the condenser and improve the reliability of the refrigeration system.

[0003] In conjunction with the above, it should be noted that during the production process of traditional shell and tube condensers, the completed shell and tube condensers are usually inspected, but there is a lack of pressure-bearing and leak-proof inspection of the internal cavity before the overall assembly of the internal tube bundle. As a result, some problematic tube bundles cannot be discovered in time, which subsequently affects the service life of the shell and tube condenser. In addition, due to the size of the shell and tube condenser itself and the number of connecting valve ports on the external cross-section, the traditional inspection method is not only cumbersome, time-consuming and labor-intensive, but also prone to loose assembly connections during operation, resulting in significant defects in inspection accuracy and efficiency.

[0004] In view of the above technical defects, a solution is now proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide an inner cavity pressure-bearing and anti-leakage detection device for condenser production, which is achieved by collecting data of the inner cavity pressure-bearing and anti-leakage detection device during use, and comprehensively supervising and analyzing the use process of the overall fall arrester before and during fall arrest, that is, comparing and analyzing the collected data with the preset stored data, obtaining relevant rating signals, and controlling relevant components to perform compensatory operations accordingly, thereby realizing the linkage operation process of the system and the mechanical structure, and using the mechanical structure to analyze the condenser detection process for real-time acquisition of the detection status data of the group of condensers, and real-time control of the operation of relevant mechanical components according to the signals generated by the status data, thereby realizing the diversion of condensers with different quality control levels, which is helpful for subsequent targeted treatment of condensers with excellent quality control, defective products and marks, improving the overall condenser production efficiency, and avoiding the generation of quality control anomalies into the market, to solve the problems raised.

The surface of the movable block is provided with a rubber curtain connected to the inner wall of the support ring, and the inner ring of the rubber curtain is provided with an air-intake rubber ring. The top of the movable block is provided with a telescopic hose that passes through the support ring.

[0012] Furthermore, a guide groove is provided in a depression on the top of the limiting bracket, an arc-shaped support piece is slidingly provided on the top of the guide groove, and a pushing cylinder connected to the arc-shaped support piece is provided on the inner wall of the guide groove, and the driving seat two is symmetrically provided on both sides of the material picking bracket, a lifting cylinder is provided at the bottom center of the material picking bracket, and a driving motor for connecting to the conveying roller is provided on the top of the lifting cylinder, and inflatable airbag cushions are provided in depressions on both sides of the top of the material picking bracket.

[0013] Furthermore, a detection and supervision platform is provided inside the control panel, and the detection and supervision platform is communicatively connected to a data acquisition unit, a detection feedback unit, a state analysis unit and a component control unit;

[0014] When the inspection and supervision platform generates a supervision instruction, the supervision instruction is sent to the data acquisition unit. After receiving the supervision instruction, the data acquisition unit immediately collects the air pressure value of a single tube bundle in the inspection device, analyzes the obtained air pressure value, and sends the obtained excellent sealing signal and poor sealing signal to the inspection feedback unit and the state analysis unit; after receiving the excellent sealing signal and the poor sealing signal, the inspection feedback unit immediately collects the pressure parameters of the condenser under inspection, the pressure parameters include the air pressure fluctuation value and the gas transmission loss value, analyzes the pressure parameters, sends the obtained normal signal to the state analysis unit, and sends the obtained abnormal signal to the component control unit;

[0015] When the state analysis unit receives the normal signal and the sealing poor quality signal, it obtains a pressure leakage risk signal and sends the pressure leakage risk signal to the component control unit.

[0016] Furthermore, the data acquisition unit analyzes the air pressure value as follows:

[0017] The duration between the start and end of the condenser detection by the detection device is collected and marked as a time threshold. The air pressure value in the condenser tube bundle in the detection device is obtained according to the time threshold, and the air pressure value is compared with the preset air pressure value range stored and recorded in the monitoring and supervision platform for analysis: if the air pressure value is greater than the maximum value in the preset air pressure value range, an excellent sealing signal is generated; if the air pressure value is within the preset air pressure value range, no signal is generated; if the air pressure value is less than the minimum value in the preset air pressure value range, a poor sealing signal is generated.

[0018] Furthermore, the analysis process of the detection state parameters by the detection feedback unit is as follows:

[0019] Divide the time threshold into i time nodes with 10 seconds as one node, obtain the pressure fluctuation value of the pressure injected into the tube bundle by the detection device at each time node, and obtain the difference between the pressure fluctuation values of the injected air between two consecutive sub-time nodes. This difference is marked as the injection volume difference, and a set of injection volume difference values is constructed based on this. The data difference of the injection volume difference set is obtained and marked as the difference evaluation value;

[0020] Obtain the gas loss value generated by the detection device pressurizing the tube bundle at each time node, and establish a rectangular coordinate system with time as the X-axis and the gas loss value as the Y-axis. Plot the number of gas loss values corresponding to the gas loss value change curve above the preset gas loss value threshold curve in the coordinate system, and mark it as the loss number. At the same time, obtain the total area enclosed by the gas loss value change curve above the preset gas loss value threshold curve and the preset gas loss value threshold curve, and mark it as the loss area. At the same time, mark the product of the loss number and the loss area as the abnormal area value.

[0021] The difference assessment value and the abnormal area value are compared and analyzed with the preset difference assessment value threshold and the preset abnormal area value threshold stored in the detection and supervision platform; if the difference assessment value is less than the preset difference assessment value threshold, and the abnormal area value is less than the preset abnormal area value threshold, a normal signal is generated; if the difference assessment value is greater than or equal to the preset difference assessment value threshold, and the abnormal area value is greater than or equal to the preset abnormal area value threshold, an abnormal signal is generated.

[0022] Furthermore, after receiving the normal signal and the sealing poor quality signal, the state analysis unit immediately generates a pressure leakage risk signal. When the pressure leakage risk signal is generated, the part of the air pressure value that exceeds the maximum value in the preset air pressure value range is immediately obtained and marked as the risk air pressure value. At the same time, the risk air pressure value is compared and analyzed with the preset risk air pressure value range stored and entered in the detection and supervision platform: if the risk air pressure value is greater than the maximum value in the preset risk air pressure value range, a defective material transportation signal is generated; if the risk air pressure value is within the preset risk air pressure value range, a marking signal is generated.

[0023] The beneficial effects of the present invention are:

[0024] The present invention collects data from the inner cavity pressure-bearing anti-leakage detection device during use, and comprehensively monitors and analyzes the use process of the entire fall arrester before and during fall prevention, that is, compares and analyzes the collected data with preset stored data, obtains relevant rating signals, and controls relevant components to perform compensatory operations accordingly, thereby realizing the linkage operation process of the system and the mechanical structure, and uses the mechanical structure to analyze the condenser detection process, so as to obtain the detection status data of the group of condensers in real time, and control the operation of relevant mechanical components according to the signals generated by the status data in real time, thereby realizing the diversion of condensers with different quality control levels, facilitating the subsequent targeted treatment of condensers with excellent quality control, defective products and marks, improving the overall condenser production efficiency, and preventing the occurrence of quality control anomalies from entering the market;

[0025] The present invention uses the detection kit in conjunction with the structure of the tube sealing ring to limit and fix the condenser while performing targeted sealing and coating treatments on both ends and the exposed tube bundle one by one, which helps to subsequently pressurize and inject the detection gas, realize the pressure-bearing and anti-leakage detection of the interior, and improve the pressure-bearing and anti-leakage detection accuracy of the condenser.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

The detection kit 3 comprises an outer disc sleeve 301 and an inner disc sleeve 302. The end surface of the outer disc sleeve 301 is provided with a docking valve 307 and a squeeze disc 304. The inner wall of the inner disc sleeve 302 is provided with a pipe sealing ring 7. The pipe sealing ring 7 comprises a support ring 701 and a limit ring 709. A micromotor 703 is provided on the inner wall of the support ring 701. A control panel 6 is provided on the outer wall of the support column 1.

[0042] After the shell assembly of the tube condenser is completed through the production line, it passes through the inner cavity pressure-bearing and anti-leakage detection device on the way to the next step area through the transportation device. In this state, both ends of the tube condenser are in a closed state. The transportation device is assembled with the detection device through the feeding bracket 2. The tube condenser is located at the bottom of the support column 1 and above the multiple groups of limit brackets 4;

[0043] A feeding bracket 2 is provided on the outer periphery of the bottom of the support column 1, and a secondary material connecting frame 102 is provided on the outer periphery of the top of the support column 1. A limit bracket 4 and a material taking bracket 5 are slidably provided inside the support column 1. The limit bracket 4 is provided with a driving seat 401, and a conveying roller 503 is provided on the top of the material taking bracket 5;

[0044] A lifting hydraulic cylinder 101 is embedded on the inner side walls of both ends of the support column 1, a lifting hydraulic cylinder 2 105 is provided on the adjacent end surface of the support column 1, and a crossbeam 104 is provided between the lifting hydraulic cylinders 105. A top cover 103 is provided on the top of the support column 1, and multiple groups of marking nozzles are provided on the inner wall of the top cover 103;

[0045] The outer walls of both sides of the outer disc sleeve 301 are provided with sliding members 303 connected to the inner disc sleeve 302, and the end of the outer disc sleeve 301 away from the docking valve 307 is provided with a booster cylinder 313, and the booster cylinder 313 is provided with a horizontal push plate 306 connected to the docking valve 307, and the docking valve 307 is provided with a valve seat 308 close to the outer disc sleeve 301. The booster cylinder 313 drives the inner disc sleeve 302 to slide along the inner wall of the sliding frame and approach the tube condenser through the horizontal push plate 306, until the two ends of the tube condenser pass through the inner disc sleeve 302 and abut against the squeeze plate 304, and the two ends of the pipe inside the tube condenser pass through the through holes 305 and are inserted into the docking valve 307, and the squeeze plate 304 is partially embedded in the shells at both ends of the tube condenser, thereby completing the temporary packaging of the tube condenser.

[0046] A sliding pipe 309 is provided between the docking valve 307 and the valve seat 308. An expansion rubber ring 310 is embedded on the inner wall of the end of the docking valve 307 close to the extrusion disk 304. A pressure rod 312 is hinged on the inner wall of the docking valve 307, and a pressure rod 311 is provided at the hinge point between the pressure rod 312 and the docking valve 307. A plurality of groups of through-holes 305 are provided through the surface of the extrusion disk 304. When the tube bundle is inserted into the docking valve 307, the cross section of the tube bundle port first pushes the pressure rod 312. The pressure rod 312 drives the pressure rod 311 to deflect via the hinge fitting, clamping the outer walls of both ends of the tube bundle to a limited position. The external gas supply equipment injects the test gas into the docking valve 307 through the gas pipe. The test gas passes through the valve seat 308, is pressure-regulated by the sliding pipe 309, and then is directed into the tube bundle.

[0047] During this process, the aperture of the middle part of the sliding tube 309 decreases in a conical shape, so that the sliding tube 309 is pushed and slid along the axial direction of the valve seat 308 under the pushing of the injection of the test gas, and the docking valve 307 is gradually squeezed on the cross-section of the tube bundle port, causing the pressure rod 311 to further clamp the pipe end face. At the same time, an air channel connected to the expansion rubber ring 310 is provided on the inner wall of the aperture of the sliding tube 309, guiding part of the air channel to be injected into the expansion rubber ring 310, causing the expansion rubber ring 310 to expand rapidly until the exposed area of the expansion rubber ring 310 is completely abutted between the docking valve 307 and the tube bundle, thereby achieving synchronous pneumatic sealing of the tube bundle port and continuously pressurizing the interior of the tube bundle to inject the test gas, so as to achieve pressure-bearing and leak-proof detection of the inner cavity of each tube bundle in the tube-in-tube condenser.

[0048] A metal ring 702 is provided on the inner wall of the support ring 701, which is transmission-connected to the micromotor 703. Multiple sets of arc-shaped connecting rods 706 are hinged on the inner wall of the metal ring 702. A movable block 707 is provided at the bottom of the arc-shaped connecting rod 706. A rubber curtain 704 connected to the inner wall of the support ring 701 is sleeved on the surface of the movable block 707. An air-inhaling rubber ring 708 is provided on the inner ring of the rubber curtain 704. A telescopic hose 705 is provided on the top of the movable block 707, which passes through the support ring 701.

[0049] When both ends of the tube condenser pass through the inner disk sleeve 302, the micro motor 703 drives the metal ring 702 to rotate along the inner wall of the support ring 701. The metal ring 702 drives the arc connecting rod 706 to deflect along a fixed track. A slider is provided on the inner wall between the arc connecting rod 706 and the limit ring 709. The slider drives the bottom of the arc connecting rod 706 to slide and deflect along the side of the limit ring 709. The top of the arc connecting rod 706 rotates with the metal ring 702 through the connecting piece, thereby forming a fixed track and moving the movable block 707 Push and extend until it abuts against the outer wall of the tube condenser. The movable block 707 moves while pulling the rubber curtain 704 to stretch until it drives the air-intake rubber ring 708 to adhere to the outer wall of the tube condenser. The air-intake rubber ring 708 is connected to the external air supply equipment through the telescopic air pipe, which causes the air-intake rubber ring 708 to suck and adhere to the outer wall of the tube condenser, forming an outer sealed environment. Combined with the horizontal push plate 306 and the inner plate sleeve 302, the end surface of the tube condenser is covered and sealed, blocking the interference of external air pressure on the internal detection environment;

[0050] A guide groove 402 is recessed on the top of the limiting bracket 4, and an arc-shaped support piece 403 is slidingly provided on the top of the guide groove 402, and a pushing cylinder connected to the arc-shaped support piece 403 is provided on the inner wall of the guide groove 402. The limiting bracket 4 is connected to the crossbeam 104 through the driving seat 1 401, and a servo motor connected to the crossbeam 104 is provided inside the driving seat 1 401. The lifting hydraulic cylinder 2 105 drives the limiting bracket 4 to slide axially upward through the crossbeam 104 until the arc-shaped support piece 403 contacts the outer peripheral wall of the tube condenser, and the pushing cylinder drives the arc-shaped support pieces 403 to move closer to each other until the outer peripheral wall of the tube condenser is covered from the bottom to the upper half and locked to limit, and then the tube condenser is lifted and slid upward until the two ends of the tube condenser are aligned with the center of the detection kit 3;

[0051] The material picking bracket 5 is symmetrically arranged on both sides of the driving seat 2 501, a lifting cylinder 502 is arranged at the bottom center of the material picking bracket 5, and a driving motor for connecting to the conveying roller 503 is arranged on the top of the lifting cylinder 502, and inflatable airbag cushions 504 are arranged in the depressions on both sides of the top of the material picking bracket 5. The driving seat 2 501 has the same structure as the driving seat 1 401.

[0052] Example 2: This example is a pressure-bearing and leak-proof detection device for an inner cavity used in condenser production, including a control panel 6 with a detection and supervision platform disposed therein. The detection and supervision platform is communicatively connected to a data acquisition unit, a detection feedback unit, a state analysis unit, and a component control unit. When the detection and supervision platform generates a supervision instruction, the supervision instruction is sent to the data acquisition unit. Upon receiving the supervision instruction, the data acquisition unit immediately collects the air pressure value of a single tube bundle in the detection device and analyzes the obtained air pressure value. The data acquisition unit analyzes the air pressure value as follows:

[0053] The duration between the start and end of the condenser detection by the detection device is collected and marked as a time threshold. Based on the time threshold, the air pressure value inside the condenser tube bundle in the detection device is obtained. The air pressure value is compared and analyzed with the preset air pressure value range stored and recorded in the monitoring and supervision platform:

[0054] If the air pressure value is greater than the maximum value in the preset air pressure value range, a sealing excellence signal is generated; if the air pressure value is within the preset air pressure value range, no signal is generated;

[0055] If the air pressure value is less than the minimum value of the preset air pressure value range, a poor sealing signal is generated, and the obtained excellent sealing signal and poor sealing signal are sent to the detection feedback unit and the state analysis unit.

[0056] After receiving the excellent sealing signal and the poor sealing signal, the detection feedback unit immediately collects the pressure parameters of the condenser under test, including the pressure fluctuation value and the gas transmission loss value, analyzes the pressure parameters, and sends the obtained normal signal to the status analysis unit. The detection feedback unit analyzes the detection status parameters as follows:

[0057] The time threshold is divided into i time nodes with 10 seconds as a node. The pressure fluctuation value of the pressure-injected air into the tube bundle by the detection device at each time node is obtained. Based on this, the difference between the pressure fluctuation values of the injected air in two connected sub-time nodes is obtained and marked as the injection volume difference. A set of injection volume difference values is constructed based on this. The data difference of the injection volume difference set is obtained and marked as the difference evaluation value. It should be noted that: the larger the difference evaluation value, the greater the leakage risk and abnormality of the tube condenser detection.

[0058] The gas loss value generated by the pressure increase of the tube bundle by the detection device at each time node is obtained. Based on this, a rectangular coordinate system is established with time as the X-axis and the gas loss value as the Y-axis. The number of gas loss values corresponding to the gas loss value change curve located on the preset gas loss value threshold curve is plotted in the coordinate system and marked as the loss number. At the same time, the total area enclosed by the gas loss value change curve located above the preset gas loss value threshold curve and the preset gas loss value threshold curve is obtained and marked as the loss area. At the same time, the product of the loss number and the loss area is marked as the abnormal area value. It should be noted that the larger the abnormal area value, the greater the leakage risk and abnormality in the detection of the tube condenser.

[0059] Compare and analyze the difference assessment value and the abnormal area value with the preset difference assessment value threshold and the preset abnormal area value threshold stored in the detection and supervision platform; if the difference assessment value is less than the preset difference assessment value threshold, and the abnormal area value is less than the preset abnormal area value threshold, a normal signal is generated;

[0060] If the difference evaluation value is greater than or equal to the preset difference evaluation value threshold, and the abnormal area value is greater than or equal to the preset abnormal area value threshold, an abnormal signal is generated and the obtained abnormal signal is sent to the component control unit;

[0061] When the state analysis unit receives the normal signal and the poor sealing signal, it obtains a pressure leakage risk signal and sends the pressure leakage risk signal to the component control unit. After receiving the normal signal and the poor sealing signal, the state analysis unit immediately generates a pressure leakage risk signal. When the pressure leakage risk signal is generated, the part of the air pressure value that exceeds the maximum value in the preset air pressure value range is immediately obtained and marked as a risk air pressure value. At the same time, the risk air pressure value is compared and analyzed with the preset risk air pressure value range stored and entered in the detection and supervision platform:

[0062] If the risk air pressure value is greater than the maximum value in the preset risk air pressure value range, a defective material transport signal is generated; the defective material transport signal is sent to the component control unit. When the component control unit receives the defective material transport signal and the abnormal signal, the external air supply equipment continues to suck and clean the detection gas in each tube bundle of the tube condenser. After the air supply is stopped, the expansion rubber ring 310 is deflated and reset, the booster cylinder 313 drives the horizontal push plate 306 to reset, the pressure rod 312 moves away from the tube bundle end section, and drives the pressure rod 311 to reset away from the outer wall of the tube bundle. The lifter hydraulic cylinder 2 drives the limit bracket 4 to slide down and reset through the crossbeam 104 until the tube condenser is placed back on the transport device, and generates "device n / spot inspection abnormality / internal pressure leakage and damage" style text according to the defective material transport signal and the abnormal signal and sends it to the display screen of the production control room for reminding the supervisor and recording the abnormal information, where n is a natural number greater than zero;

[0063] If the risk air pressure value is within the preset risk air pressure value range, a marking signal is generated; the generated marking signal is sent to the component control unit. When the component control unit receives the generated marking signal and the abnormal signal, the marking conveyor rack is connected to the other end of the secondary material connecting rack 102. When it slides on the shell and tube condenser to the secondary material connecting rack 102 area, the marking nozzle on the inner wall of the top cover 103 sprays marks on the outer wall of the group of shell and tube condensers, and the material picking bracket lifts the group of shell and tube condensers and transfers them to the marking conveyor rack. According to the marking signal and the abnormal signal, the "device n / spot inspection abnormality / tube bundle i / repairable" style text is generated and sent to the display screen of the production control room for reminding supervisors and recording abnormal information, and i is a natural number greater than zero.

[0064] In combination with Example 1 and Example 2, it can be seen that the system and the mechanical structure can be operated in a linked manner, and the mechanical structure can be used to analyze the condenser detection process, so as to obtain the detection status data of the group of condensers in real time, and control the operation of related mechanical components in real time according to the signals generated by the status data, so as to realize the diversion of condensers with different quality control levels, and help to carry out targeted treatment of condensers with excellent quality control, defective products and marks in the future, improve the overall condenser production efficiency, and avoid the generation of quality control anomalies into the market.
