Description

Technical Field

[0001] The invention relates to the technical field of air pipe detection, and in particular to a compressor air pipe sealing detection device and a detection process. Background Art

[0002] Compressors are usually used for high-pressure, high-speed gas compression and transmission. If the air pipe is not sealed properly, it may cause gas leakage. This will not only cause energy waste, but also may cause safety accidents such as explosions and fires. Therefore, sealing detection of air pipes after production is a necessary measure to ensure the safe operation of compressors.

[0003] At present, there are usually two ways to test the sealing of compressor air pipes. The first is to use the soap bubble method and water immersion method. A certain pressure of leak-indicating gas (usually air or nitrogen) is filled into the air pipe, and soap liquid is applied to the air pipe or the air pipe is placed in water to observe whether bubbles are formed. If bubbles are formed, it indicates a leak. The second is the pressure detection method. A certain amount of gas is also filled into the air pipe, and a pressure sensor is used to detect the pressure change in the air pipe. If the pressure decreases, it indicates a leak. However, in actual application, both methods have certain disadvantages. For the first method: the existing compressor air pipes are usually mass-produced, so the number of air pipes to be tested is large. When using the soap bubble method and the water immersion method for testing, regardless of whether there is a leak, the air pipes after testing need to be cleaned and dried, which is relatively cumbersome; for the second method: although the pressure detection method does not require processing of the air pipes after detection, during the detection process, if the air pipe leaks, the leak point cannot be effectively located, and the first method is still required to further locate the leak point. Summary of the invention

[0014] A compressor air pipe sealing detection process, applied to the above compressor air pipe sealing detection device, comprises the following steps: The adjusting module drives the first positioning plate and the second positioning plate to separate from each other, and places the trachea body between the first positioning plate and the second positioning plate; After placement, the adjustment module drives the first positioning plate and the second positioning plate to approach each other, so as to position the trachea body in the circular groove; The feeding module feeds the positioned air pipe body into the detection box along the feeding port; The first gas transmission module inputs oxygen into the detection box, and the second gas transmission module inputs a certain amount of nitric oxide gas into the trachea body, and keeps both ends of the trachea body sealed; If there is a leak in the trachea itself, the nitric oxide gas will be discharged along the leak point and come into contact with oxygen, followed by the production of reddish-brown nitrogen dioxide gas, which allows the inspector to locate the leak point. After the detection is completed, the feeding module can discharge the air pipe body.

[0015] Beneficial effects of the present invention: After the positioned trachea body is transported to the detection box, the present invention first inputs oxygen into the detection box through the first gas transmission module, and then inputs a certain amount of nitric oxide gas into the trachea body through the second gas transmission module, and keeps the two ends of the trachea body sealed. If the trachea body leaks, the nitric oxide gas can be discharged along the leak point and contact with oxygen, thereby generating reddish-brown nitrogen dioxide gas, and the detection personnel can locate the leak point. Accordingly, the present invention can set multiple monitors in the detection box to monitor the trachea body. If no reddish-brown gas is generated during the detection process, it means that the trachea body is not leaking. Through the detection method of the present invention, not only can the leak point be located, but also during the detection process, the trachea body will not be attached to the detection liquid, so there is no need for subsequent cleaning and drying treatment, which effectively improves the detection accuracy and efficiency and facilitates the mass production of compressor trachea. During feeding, as the first positioning plate and the second positioning plate push the sealing plate to shrink into the detection box, the sealing box is also synchronously embedded in the feed port, and the outer edge surface of the sealing box slides and fits with the side wall of the feed port, thereby achieving the effect of sealing the feed port, and the gas in the detection box will not be discharged; accordingly, when the first positioning rod and the second positioning rod push the sealing strip to slide along the slide groove, the sealing rod is also synchronously embedded in the slide groove to seal the slide groove to ensure the sealing of the detection box. After the first gas transmission module inputs oxygen into the detection box, it can be reused to avoid oxygen leakage, reduce costs, and at the same time, avoid nitrogen dioxide discharge to cause air pollution; In the initial state of the present invention, the partition is in a state of sealing the support tube, and the oxygen in the detection box will not enter the support tube. As the trachea body moves into the detection box and pushes the sealing plate to move, the sealing plate can synchronously push the partition to deviate to one side of the support tube until the trachea body is connected with the support tube. In this process, oxygen will not enter the support tube, further ensuring the subsequent detection accuracy of the sealing of the trachea body. In the present invention, in the initial state, the conical inclined surface at the end of the positioning terminal protrudes to the outside of the support tube, and as the feeding module drives the trachea body to move into the detection box, the edges on both sides of the first positioning plate first abut against the conical inclined surface to compress the positioning terminal into the support tube, and at this time the third spring is deformed and generates elastic force, and when the trachea body moves to the position corresponding to the support tube, based on the elastic force of the third spring, the positioning terminal can be driven to embed into the pipe mouth of the trachea body, and at this time the conical inclined surface abuts against the pipe mouth, thereby realizing the re-positioning of the trachea body, even if the first positioning plate and the second positioning plate are separated from each other subsequently, the trachea body will not fall, and when the first positioning plate and the second positioning plate are close to each other, the trachea body can be embedded in the circular groove to facilitate discharge.

[0019] The technical scheme of the present invention will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example 1 See also Figure 1-Figure 2 As shown, the present invention is a compressor air pipe sealing detection device, comprising a detection platform 1, a detection box 2 is fixedly arranged on the detection platform 1, a first gas transmission module is arranged on the detection box 2, and the first gas transmission module is used to input oxygen into the detection box 2; A positioning module 5 for positioning the trachea body 8 is also arranged on one side of the detection box 2, wherein a feed port 201 is provided on the side of the detection box 2 close to the positioning module 5, and a feed module 101 is also provided on the detection table 1 to input the positioned trachea body 8 into the detection box 2; specifically, in this embodiment, when inspecting the trachea body 8 of the compressor, the trachea body 8 is first positioned and fixed on the outside of the detection box 2 by the positioning module 5. After the positioning is completed, the positioned trachea body 8 can be input into the detection box 2 through the feeding module 101 for subsequent inspection.

[0021] In this embodiment, a second gas delivery module is also arranged in the detection box 2, and the second gas delivery module is used to deliver nitric oxide into the tracheal body 8; It should be noted that nitric oxide and oxygen, two colorless gases, will change color when in contact; specifically, after nitric oxide reacts with oxygen, it can quickly generate reddish-brown nitrogen dioxide gas; this chemical reaction can be expressed as: ; Therefore, in this embodiment, after the positioned tracheal body 8 is transported to the detection box 2, oxygen is firstly input into the detection box 2 through the first gas transmission module, and then a certain amount of nitric oxide gas is input into the tracheal body 8 through the second gas transmission module, and the two ends of the tracheal body 8 are kept sealed. If the tracheal body 8 leaks, the nitric oxide gas can be discharged along the leak point and contact with oxygen, thereby generating reddish-brown nitrogen dioxide gas, and the detection personnel can locate the leak point. Accordingly, in this embodiment, multiple monitors 801 can be set in the detection box 2 to monitor the tracheal body 8 (see Fig.12 ), if no reddish-brown gas is generated during the detection process, it means that the air pipe body 8 is not leaking. The detection method of this embodiment can not only locate the leak point, but also during the detection process, no detection liquid will adhere to the air pipe body 8, so there is no need for subsequent cleaning and drying treatment, which effectively improves the detection accuracy and efficiency and facilitates the mass production of compressor air pipes.

[0022] In addition, when the first gas transmission module of the present embodiment inputs oxygen into the detection box 2 and the second gas transmission module inputs nitric oxide into the tracheal body 8, the pressure in the tracheal body 8 needs to be greater than the pressure in the detection box 2 to prevent the oxygen in the detection box 2 from entering the tracheal body 8 along the leak point. At the same time, since the pressure in the tracheal body 8 is relatively high, if there is a leak point, nitric oxide can be quickly discharged and combined with oxygen, and the detection rate is higher. Specifically, the pressure value can be detected by setting a pressure sensor at the gas transmission end of the first gas transmission module and the second gas transmission module. This detection method is a prior art, and the present embodiment does not limit its specific structure.

[0023] Example 2 Based on Example 1, please refer to Figure 3-Figure 5The positioning module 5 includes a first positioning plate 501 and a second positioning plate 502 arranged on the detection platform 1. The upper surface and the lower surface of the first positioning plate 501 and the second positioning plate 502 are flush. The first positioning plate 501 and the second positioning plate 502 are close to each other. A semicircular groove 513 is opened on the side. When the first positioning plate 501 and the second positioning plate 502 are fitted, the two groups of semicircular grooves 513 are enclosed to form a circular groove for positioning the tracheal body 8; wherein, the detection platform 1 is provided with a layout adjustment module, and the adjustment module is used to drive the first positioning plate 501 and the second positioning plate 502 to move. The second positioning plates 502 are close to or away from each other; it can be explained that before the tracheal body 8 is tested, the first positioning plate 501 and the second positioning plate 502 are located outside the test box 2. In this embodiment, the first positioning plate 501 and the second positioning plate 502 can be driven to separate from each other by the adjustment module, so as to facilitate the tracheal body 8 to be placed between the first positioning plate 501 and the second positioning plate 502. After placement, the first positioning plate 501 and the second positioning plate 502 can be driven to move closer to each other by the adjustment module to position the tracheal body 8 in the circular groove (see Fig.13 ), and then the positioned air pipe body 8 can be fed into the detection box 2 along the feed port 201 through the feed module 101 (see Fig.14 After the first gas delivery module and the second gas delivery module complete gas delivery, the regulating module drives the first positioning plate 501 and the second positioning plate 502 to move away from each other again, so that the air pipe body 8 can be completely exposed in the detection box 2 (see Fig.15 ), in order to monitor the leakage point; after the detection is completed, the adjustment module drives the first positioning plate 501 and the second positioning plate 502 to move closer to each other to position the trachea body 8, and finally the trachea body 8 can be pulled out along the feed port 201 through the feeding module 101.

[0024] In addition, the feeding module 101 of this embodiment can adopt a screw nut transmission mechanism or a synchronous belt transmission mechanism, which is not limited in this embodiment, so as to satisfy the actual driving of the positioning module 5 to reciprocate along a straight line on the detection platform 1.

[0025] In this embodiment, please refer to Figure 3-Figure 4, a first positioning rod 506 is vertically fixedly arranged on one side of the bottom of the first positioning plate 501, and a second positioning rod 504 is vertically fixedly arranged on the other side of the bottom of the second positioning plate 502. An adjusting rod 507 is vertically fixedly arranged on one side of the first positioning rod 506 and the second positioning rod 504. The end of the adjusting rod 507 is fixed to an adjusting seat 508, and the adjusting seats 508 on both sides are respectively slidably sleeved on the support rod 509. Among them, the adjusting module includes a lifting cylinder 102 fixedly arranged on the driving end of the feeding module 101, and a U-shaped frame 510 fixed to the support rod 509 is fixedly arranged on the outer side of the lifting cylinder 102. The telescopic end of the lifting cylinder 102 is fixed to a lifting seat 511, and lifting rods 512 are rotatably arranged on both sides of the lifting seat 511. The other end of the lifting rod 512 is rotatably sleeved on the adjusting seat 508 Connection; It can be explained that, in this embodiment, when the air pipe body 8 is driven to feed into the detection box 2 after positioning, the lifting cylinder 102 can be driven to move through the feeding module 101, and the lifting cylinder 102 can synchronously drive the first positioning plate 501 and the second positioning plate 502 to move through the U-shaped frame 510, the support rod 509, the lifting rod 512, the adjusting rod 507 and the first positioning rod 506 and the second positioning rod 504. Accordingly, when it is necessary to adjust the distance between the first positioning plate 501 and the second positioning plate 502, the lifting seat 511 can be driven to rise and fall through the lifting cylinder 102, and the lifting seat 511 can drive the adjusting seat 508 to slide on the support rod 509 through the lifting rod 512, and the adjusting seat 508 can synchronously drive the first positioning plate 501 and the second positioning plate 502 to move closer or farther from each other through the adjusting rod 507.

[0026] Accordingly, in this embodiment, when the feeding module 101 drives the first positioning plate 501 and the second positioning plate 502 to move along the feeding port 201, in order to avoid the first positioning rod 506 and the second positioning rod 504 from interfering with the bottom of the detection box 2, the feeding module 101 can refer to Figure 6 , slide grooves 208 for embedding the first positioning rod 506 and the second positioning rod 504 are respectively opened on both sides of the bottom of the detection box 2; specifically, when the first positioning plate 501 and the second positioning plate 502 move along the feed port 201, the first positioning rod 506 and the second positioning rod 504 can move synchronously along the slide groove 208.

[0027] As a further solution of this embodiment, in order to prevent oxygen or nitrogen dioxide from being discharged along the feed port 201 or the chute 208, please refer to Figure 6A sealing plate 202 is slidably embedded at the feed port 201, and the sealing plate 202 is connected to a first elastic part arranged in the detection box 2, and a sealing strip 204 is slidably embedded in the slide grooves 208 on both sides, and the sealing strip 204 is connected to a second elastic part arranged on the outside of the detection box 2; it can be explained that in the initial state, based on the setting of the first elastic part and the second elastic part, the sealing plate 202 is in a state of sealing the feed port 201, and the sealing strip 204 is in a state of sealing the slide groove 208. When the trachea body 8 feeds into the detection box 2, as the positioning plate and the positioning rod move, the sealing plate 202 and the sealing strip 204 can be squeezed to slide in a direction away from the positioning module 5, the sealing plate 202 squeezes the first elastic part and generates an elastic force, and the sealing strip 204 squeezes the second elastic part and generates an elastic force. When the positioning module 5 is reset, the sealing plate 202 and the sealing strip 204 can be driven to reset by the elastic part.

[0028] See also Figure 7 The first elastic part includes a first guide rod 210 fixed in the detection box 2, an L-shaped support plate 209 is fixedly arranged on one side of the sealing plate 202, the L-shaped support plate 209 is slidably sleeved on the first guide rod 210, and a first spring 211 is provided on the first guide rod 210, one end of the first spring 211 is fixed to the L-shaped support plate 209, and the other end is fixed to the end of the first guide rod 210; it can be explained that as the sealing plate 202 moves, the first spring 211 can be squeezed by the L-shaped support plate 209 and an elastic force can be generated.

[0029] See also Figure 2 The second elastic portion includes a through slot 203 which is opened on the detection box 2 and corresponds to the position of the slide slot 208. The sealing strip 204 passes through the through slot 203 and is fixed to the guide plate 205. A second guide rod 206 is fixedly arranged on the outside of the detection box 2. The guide plate 205 is slidably sleeved on the second guide rod 206. A second spring 207 is provided on the second guide rod 206. One end of the second spring 207 is fixed to the guide plate 205, and the other end is fixed to the end of the second guide rod 206. It can be explained that as the sealing strip 204 moves, the second spring 207 can be squeezed by the guide plate 205 and an elastic force is generated.

[0030] In addition, in the present embodiment, the first positioning plate 501 and the second positioning plate 502 can form a complete rectangular parallelepiped structure after being combined, so that when passing through the feed inlet 201, the outer edges of the first positioning plate 501 and the second positioning plate 502 slide and fit with the side wall of the feed inlet 201, and the gas in the detection box 2 will not be discharged from the gap between the positioning plate and the feed inlet 201. Accordingly, when the sealing strip 204 slides along the slide groove 208, the outer edge of the sealing strip 204 can slide and fit with the groove wall of the slide groove 208, and the fixed gas in the detection box 2 will not be discharged from the gap between the sealing strip 204 and the slide groove 208. As a further solution of this embodiment, please refer to Figure 4-Figure 6 , a sealing box 505 is fixedly arranged on the side of the second positioning plate 502 away from the detection box 2, wherein the sealing rod 503 is fixedly arranged on the end of the first positioning rod 506 and the second positioning rod 504 away from the detection box 2, respectively, and the sealing rod 503 extends in the direction away from the detection box 2, and the width of the sealing rod 503 is equal to the width of the sealing strip 204; it can be explained that when feeding, as the first positioning plate 501 and the second positioning plate 502 push the sealing plate 202 to shrink into the detection box 2, the sealing box 505 is also synchronously embedded in the feed port 201, and the outer edge surface of the sealing box 505 slides and fits with the side wall of the feed port 201, thereby achieving the effect of sealing the feed port 201, and the gas in the detection box 2 will not be discharged; accordingly, when the first positioning rod 506 and the second positioning rod 504 push the sealing strip 204 to slide along the slide groove 208, the sealing rod 503 is also synchronously embedded in the slide groove 208 to seal the slide groove 208 to ensure the sealing of the detection box 2; Therefore, in the present embodiment, during the process of feeding and discharging the trachea body 8, the sealing of the detection box 2 can always be maintained. After the first gas transmission module inputs oxygen into the detection box 2, it can be reused to avoid oxygen leakage, reduce costs, and at the same time, avoid air pollution caused by the discharge of nitrogen dioxide.

[0031] See also Figure 1-Figure 2 as well as Fig.12 The first gas transmission module includes a first air pump 3 fixed on the detection box 2, an exhaust box 307 is fixedly arranged in the detection box 2, and a plurality of exhaust holes 308 are arranged at the bottom of the exhaust box 307. The exhaust box 307 is connected to the first air pump 3 through a first air pipe 306, and one end of the first air pump 3 away from the first air pipe 306 is connected to a three-way valve 301, one end of the three-way valve 301 is connected to a recovery tank 305 through a second air pipe 303, and the other end of the three-way valve 301 is connected to an oxygen storage tank 304 through a third air pipe 302; It can be explained that in this embodiment, when oxygen is input into the detection box 2, First, the third air pipe 302 is switched to be connected with the first air pump 3 through the three-way valve 301. The first air pump 3 can transport the oxygen in the oxygen storage tank 304 to the exhaust box 307 through the third air pipe 302, and finally discharge it into the detection box 2 through the exhaust hole 308; accordingly, when the air pipe body 8 leaks, the present embodiment can switch the second air pipe 303 to be connected with the recovery tank 305 through the three-way valve 301, and the first air pump 3 draws the nitrogen dioxide and the remaining oxygen in the detection box 2 into the recovery tank 305 for recovery to avoid interference with subsequent detection, and pure oxygen can be input again.

[0032] Furthermore, after the trachea body 8 is input into the detection box 2, as the first positioning plate 501 and the second positioning plate 502 are separated from each other, in order to prevent the trachea body 8 from falling after losing the positioning function, in this embodiment, it can be referred to Figure 7-Figure 11, support tubes 703 are fixedly arranged on both sides of the detection box 2, and positioning end heads 704 are slidably embedded in the support tubes 703. The outer peripheral surface of the side close to the positioning end heads 704 on both sides is set as a conical inclined surface 709, wherein the side away from the support tubes 703 on both sides is fixedly arranged with a limiting rod 705, and a limiting plate 707 fixedly connected to the positioning end heads 704 is slidably sleeved on the limiting rod 705. A third spring 706 is provided on the limiting rod 705, one end of the third spring 706 is fixed to the support tube 703, and the other end is fixed to the limiting plate 707; It can be explained that in the initial state, the fixed The conical inclined surface 709 at the end of the positioning end 704 protrudes to the outside of the support tube 703. As the feeding module 101 drives the trachea body 8 to move into the detection box 2, the edges on both sides of the first positioning plate 501 first abut against the conical inclined surface 709 to compress the positioning end 704 into the support tube 703. At this time, the third spring 706 is deformed and generates elastic force. When the trachea body 8 moves to the position corresponding to the support tube 703, based on the elastic force of the third spring 706, the positioning end 704 can be driven to embed into the pipe opening of the trachea body 8. At this time, the conical inclined surface 709 abuts against the pipe opening (see Fig.11 ), thereby realizing the re-positioning of the trachea body 8. Even if the first positioning plate 501 and the second positioning plate 502 are separated from each other later, the trachea body 8 will not fall. When the first positioning plate 501 and the second positioning plate 502 are close to each other, the trachea body 8 can be embedded in the circular groove to facilitate discharge.

[0033] See also Figure 1-Figure 2 as well as Figure 8 The second gas transmission module includes a second air pump 4 fixed on the outside of the detection box 2, the second air pump 4 is connected to the nitric oxide storage tank 402, the other end of the second air pump 4 is connected to the fourth air pipe 401, the fourth air pipe 401 passes through the side wall of the detection box 2 and is connected to one of the positioning terminals 704 on one side, wherein the positioning terminal 704 on the side is provided with a gas transmission channel connected to the fourth air pipe 401 at the axis center, and the positioning terminal 704 on the other side is fixed to a guide shaft 403 slidably arranged on the detection box 2; it can be explained that after the positioning terminals 704 on both sides position the air pipe body 8, the second air pump 4 can be started, and the second air pump 4 extracts the nitric oxide in the nitric oxide storage tank 402 and transports it to the positioning terminal 704 through the fourth air pipe 401, and finally transports it to the air pipe body 8 through the gas transmission channel; In addition, a telescopic tube is also provided in the fourth air pipe 401 , so that the positioning end head 704 connected thereto can slide in the support tube 703 .

[0034] In this embodiment, please refer to Figure 3-Figure 5 as well as Figure 7-Figure 11In the process of the air pipe body 8 entering the detection box 2, in order to prevent the oxygen in the detection box 2 from entering the pipe, baffles 6 are slidably arranged on both sides of the sealing box 505, and the baffles 6 on both sides extend to the feed port 201 (see Figure 1 ), a support 602 is fixedly arranged in the sealing box 505, a slide seat 603 is slidably arranged on the support 602, guide grooves 601 are respectively provided on both sides of the sealing box 505, and the slide seat 603 is fixed to the baffle 6 through a connecting rod penetrating the guide groove 601, wherein a fourth spring 604 is provided on the support 602, one end of the fourth spring 604 is fixed to the box wall of the sealing box 505, and the other end is fixed to the slide seat 603; it can be explained that in the initial state, the baffles 6 on both sides can seal the tube openings on both sides of the trachea body 8, and as the trachea body 8 moves into the detection box 2, oxygen can be prevented from entering the tube, see Fig.14 When the tracheal body 8 continues to move, the baffles 6 on both sides stop moving under the abutment of the support tube 703 until the tracheal body 8 moves to communicate with the support tube 703.

[0035] It should also be noted that before the tracheal body 8 is connected to the support tube 703, the oxygen in the detection box 2 will enter the support tube 703. When the tracheal body 8 is connected to the support tube 703, the oxygen will still enter the tracheal body 8, thereby causing detection errors. Figure 7-Figure 9 , a partition 7 is arranged on the side close to the support tubes 703 on both sides, and the partition 7 is slidably fitted with the support tube 703. A sleeve 702 is fixedly arranged in the detection box 2, and the sleeve 702 is slidably inserted and arranged with a telescopic rod 701 on one side of the support tube 703, and the other end of the telescopic rod 701 is fixed to the partition 7, wherein a fifth spring 708 fixedly connected to the telescopic rod 701 is also fixedly arranged in the sleeve 702; it can be explained that in the initial state, the partition 7 is in a state of sealing the support tube 703, and the oxygen in the detection box 2 will not enter the support tube 703. As the trachea body 8 moves into the detection box 2 and pushes the sealing plate 202 to move, the sealing plate 202 can synchronously push the partition 7 to deviate to one side of the support tube 703 (see Fig.14 ), until the tracheal body 8 is connected to the support tube 703. During this process, oxygen will not enter the support tube 703, further ensuring the subsequent detection accuracy of the sealing of the tracheal body 8.

[0036] A detection process of a compressor air pipe sealing detection device comprises the following steps: See also Figure 3-Figure 5 , S1, the adjustment module drives the first positioning plate 501 and the second positioning plate 502 to separate from each other, and places the trachea body 8 between the first positioning plate 501 and the second positioning plate 502; S2. After placement, the first positioning plate 501 and the second positioning plate 502 are driven to approach each other by the adjustment module to position the trachea body 8 in the circular groove; See also Figure 1-Figure 3 , S3, the feeding module 101 feeds the positioned air pipe body 8 into the detection box 2 along the feeding port 201; S4, the first gas transmission module inputs oxygen into the detection box 2, and the second gas transmission module inputs a certain amount of nitric oxide gas into the tracheal body 8, and keeps both ends of the tracheal body 8 sealed; S5. If the trachea body 8 leaks, the nitric oxide gas is discharged along the leak point and contacts with oxygen, thereby generating reddish-brown nitrogen dioxide gas, and the inspector can locate the leak point; S6. After the detection is completed, the feeding module 101 discharges the air pipe body 8.
