Description

Technical Field

[0001] The invention relates to the technical field of sample retention and sampling, in particular to an automatic liquid sample retention and sampling device. Background Art

[0002] A retention sample is a sample taken from a batch of products and retained for possible subsequent inspection, review, traceability, or research. Retention samples are typically collected during the production, inspection, or distribution process to ensure that original samples are available for analysis and judgment in the event of quality issues or disputes.

[0041] See also Figures 1 to 13 , the present invention provides a technical solution: Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown, it includes a retention tube 1, which is used for retaining the dyeing liquid of the leather base fabric, and a bracket 2 is fixedly connected to the outside of the retention tube 1;

[0042] A diversion mechanism 3, which is used for diverting water and leather-based fabric dyeing liquid;

[0043] A sampling mechanism 4, which is used for sampling the dyeing liquid of the leather base fabric;

[0044] The diversion mechanism 3 is fixedly installed on the top of the retention tube 1 , and the sampling mechanism 4 is fixedly installed on the bottom of the retention tube 1 .

[0045] The diversion mechanism 3 includes an inlet pipe 31, which is fixedly connected to the top of the retention pipe 1. A filter assembly 35 is provided on the top of the inlet pipe 31. Diversion assemblies 34 are symmetrically connected to both sides of the inlet pipe 31. A lap plate 32 is provided below the diversion assembly 34. The lap plate 32 is fixedly connected to the outside of the retention pipe 1. A timing retractor 33 is fixedly connected to the top of the lap plate 32. The top of the timing retractor 33 is fixedly connected to the diversion assembly 34.

[0046] The diversion component 34 includes a penetration plate 341, and the surface of the penetration plate 341 is respectively provided with a liquid inlet hole 342 and a water inlet hole 343, wherein the liquid inlet hole 342 is arranged above the water inlet hole 343, and the outer side of the penetration plate 341 is fixedly connected to the No. 1 magnet 344, and the side of the penetration plate 341 away from the No. 1 magnet 344 is fixedly connected to a folding rod 345, and the outer side of the folding rod 345 is fixedly connected to a square pressure frame 346, and the end of the folding rod 345 away from the penetration plate 341 is fixedly connected to the filter component 35, and the surface of the penetration plate 341 is respectively connected with a water inlet pipe 347 and a liquid inlet pipe 348. By starting the timing telescopic device 33 and letting it shrink, the penetration plate 341 connected to the telescopic end thereof will move downward, and then the penetration plate 341 opened in the penetration plate The water inlet hole 343 on the surface of the plate 341 will be connected to the water inlet pipe 347. At this time, the timing retractor 33 will stop and start timing. At the same time, water will enter the interior of the inlet pipe 31 through the water inlet pipe 347 from the external water inlet connected to the water inlet pipe 347. The bottom of the inlet pipe 31 is connected to the retention pipe 1, so the water flow will quickly clean the retention pipe 1 and the inlet pipe 31. The water has a certain amount of heat, and the hot water can quickly remove the residual liquid or viscous impurities in the pipe. At the same time, the water vapor will also take away some impurities and residual gas. Finally, the water will flow out from the inner perforation 432 opened on the surface of the bottom sliding column 431, thereby playing a role in cleaning the entire sampler. The water inlet pipe 347 is arranged just above the liquid inlet pipe 348, the bottom of the insertion plate 341 is fixedly connected to the telescopic end of the timing telescope 33, the internal rotation of the liquid inlet pipe 348 is connected to the blocking plate 349, and the inner side of the blocking plate 349 is fixedly connected to the second magnet 340, wherein in the process of the liquid inlet hole 342 being connected to the liquid inlet pipe 348, the first magnet 344 fixedly connected to the surface of the insertion plate 341 will enter the interior of the liquid inlet pipe 348 and generate an attraction relationship with the second magnet 340, and then the blocking plate 349 connected to the second magnet 340 will deflect clockwise, wherein the initial function of the blocking plate 349 is to block the water inlet hole 343 to prevent the leather-based fabric dyeing liquid from flowing into the water inlet hole 343, and the function after flipping is The dyeing liquid of the leather-based fabric can flow inward through the liquid inlet hole 342. The water inlet pipe 347 and the liquid inlet pipe 348 are fixedly connected to the outside of the inlet pipe 31. The water inlet pipe 347 and the liquid inlet pipe 348 are fixedly connected to the end close to the inlet pipe 31 with a fixing ring 3403. The outside of the fixing ring 3403 is rotatably connected with an elastic patch 3404. The elastic patch 3404, which is rotatably connected to the inside of the water inlet pipe 347 and the liquid inlet pipe 348 through the fixing ring 3403, is elastic. It serves to separate the water inlet pipe 347 and the liquid inlet pipe 348 when the insertion plate 352 is not inserted into the inside of the inlet pipe 31. The inside of the inlet pipe 31 is fixedly connected with an inner support frame 3401, and the top of the inner support frame 3401 is fixedly connected with a vertical top rod 3402.

[0047] The filter assembly 35 includes a top connecting rod 351, the top of the top connecting rod 351 is fixedly connected to the folding rod 345, the bottom of the top connecting rod 351 is fixedly connected to an insert plate 352, and the center of the insert plate 352 is fixedly connected to a filter screen 353. Then, when the timing retractor 33 is finished, it will continue to start and retract, and then the interpenetrating plate 341 connected thereto will continue to move downward, and at the same time, the external water inlet will also be removed from the water inlet pipe 347. Therefore, when the timing retractor 33 is retracted to the shortest length, the liquid inlet hole 342 provided on the surface of the interpenetrating plate 341 will be connected to the liquid inlet pipe 348, and then the external liquid inlet connected to the liquid inlet pipe 348 will have the leather base cloth dyeing liquid enter the inlet pipe 31 through the liquid inlet pipe 348. In addition, the inner part of the interpenetrating plate 341 The side is connected to the folding rod 345, so the top connecting rod 351 connected to the other end of the folding rod 345 will move downward with the insertion plate 352 and insert it into the interior of the inlet pipe 31, wherein the interior of the insertion plate 352 is fixedly connected to the filter screen 353, so when the liquid inlet hole 342 is connected to the liquid inlet pipe 348, the filter screen 353 will extend into the interior of the inlet pipe 31 and filter the impurities inside the leather-based fabric dyeing liquid. Because the analysis and detection is for the main components of the liquid itself, and the presence of impurities will interfere with the detection process or affect the accuracy of the detection results, it is necessary to take appropriate methods to remove impurities when taking samples. The insertion plate 352 is inserted into the top of the inlet pipe 31 and extends to the interior, and the top of the top connecting rod 351 is fixedly connected to the sealing component 354.

[0048] The sealing assembly 354 includes a bent rod 3541, one end of the bent rod 3541 is fixedly connected to the top of the top connecting rod 351, and the end of the bent rod 3541 away from the top connecting rod 351 is fixedly connected to an elastic strip 3542, and the bottom of the elastic strip 3542 is fixedly connected to a center ring 3543, and the inner rotation of the center ring 3543 is connected to an annular blocking plate 3544, wherein the number of the annular blocking plates 3544 is two, and the bottom of the annular blocking plates 3544 is squeezed and adapted to the vertical top rod 3402. In addition, when the top connecting rod 351 moves downward, the bent rod 3541 fixedly connected to its top will move downward, and the bottom of the bent rod 3541 The end is fixedly connected to the elastic strip 3542, and the elastic strip 3542 is elastic. Then the center ring 3543 connected to the bottom end of the elastic strip 3542 will move downward and enter the interior of the inlet pipe 31, and at the same time, the ring blocking plate 3544 connected to the inside of the center ring 3543 will also enter the interior of the inlet pipe 31. The moment the center ring 3543 just enters the interior of the inlet pipe 31, water will enter the inlet pipe 31 through the water inlet pipe 347. The purpose of the center ring 3543 and the ring blocking plate 3544 blocking the top of the inlet pipe 31 is to prevent rapid heat loss and incomplete cleaning. However, as the top connecting rod 351 continues to move downward, and the liquid inlet hole 342 has not yet been connected to the liquid inlet pipe 348, the annular blocking plate 3544 will be impacted by the vertical top rod 3402 and deflected upward, thereby causing the hot air to dissipate outward. In addition, when the elastic strip 3542 is compressed to the shortest length, the liquid inlet hole 342 will be fully connected to the liquid inlet pipe 348.

[0049] like Figure 10 、 Figure 11 、 Figure 12 and Figure 13 As shown, the sampling mechanism 4 includes a sampling tube 41, which is fixedly installed on the outside of the retention tube 1. A layered inner frame 42 is provided next to the sampling tube 41, and the layered inner frame 42 is fixedly connected to the inside of the retention tube 1, wherein both ends of the layered inner frame 42 are provided with holes, and the bottom of the retention tube 1 is slidably adapted to be equipped with a sample retention component 43. The leather-based fabric dyeing liquid retained in the retention tube 1 is first allowed to stand for a period of time. At this time, the layered inner frame 42 will divide the leather-based fabric dyeing liquid into several layers, and then the operator manually operates the sampling tube 41 to achieve the purpose of sampling and detecting the liquid at different layers of the leather-based fabric dyeing liquid.

[0050] The sample retention component 43 includes a bottom sliding column 431, which is inserted into the bottom of the retention tube 1. A hole groove 436 is provided on the surface of the bottom sliding column 431, and an inner through hole 432 is provided at the bottom of the bottom sliding column 431. The inside of the hole groove 436 and the inner through hole 432 are both provided with an insertion rod 433, which is fixedly connected to the inside of the bottom sliding column 431. The bottom of the insertion rod 433 is fixedly connected to a compensation cross bar 434, and the end of the compensation cross bar 434 away from the insertion rod 433 is fixedly connected to the square pressure frame 346. In the process of the insertion plate 341 moving downward, the folding rod 345 connected to the inner side thereof is fixedly connected to the square pressure frame 346. 6 is connected, so the compensation horizontal bar 434 fixedly connected to the bottom of the square pressure frame 346 will move downward accordingly, and the outer side of the compensation horizontal bar 434 is also connected to the insertion rod 433, and the outer side of the insertion rod 433 is connected to the bottom sliding column 431, so the bottom sliding column 431 will extend downward along the bottom of the inner cavity of the retention tube 1, but the downward sliding of the bottom sliding column 431 will be divided into three stages. The first stage is when the water inlet hole 343 is connected to the water inlet pipe 347, the bottom sliding column 431 will slide downward accordingly, but the top of the inner perforation 432 opened on its surface is still inside the retention tube 1, so the water The second stage is when the water flows out completely and the liquid inlet hole 342 is in the process of being fully connected with the liquid inlet pipe 348, that is, part of the space of the liquid inlet hole 342 is connected with the liquid inlet pipe 348, but in the process of being fully connected, the bottom slide 431 will continue to slide downward, and the inner perforation 432 will be completely outside the retention pipe 1, and the hole groove 436 opened on the surface of the bottom slide 431 will be partly inside the retention pipe 1, and the other half will be outside the retention pipe 1. Therefore, part of the leather base fabric dyeing liquid flowing out of the liquid inlet pipe 348 is It will pass through the inlet pipe 31 and the retention pipe 1 in turn, and finally flow out from the hole groove 436 and enter the sample tube 435. The third stage is when the liquid inlet hole 342 is fully connected with the liquid inlet pipe 348, the top of the bottom sliding column 431 will be completely blocked at the bottom of the retention tube 1, causing the leather-based fabric dyeing liquid to be unable to flow out and accumulate inside it, thereby automatically retaining part of the leather-based fabric dyeing liquid for sampling, and the remaining leather-based fabric dyeing liquid is prepared for subsequent sampling. The bottom of the compensation bar 434 is fixedly connected to the sample tube 435, and the part where the sample tube 435 is connected to the compensation bar 434 is tough.

[0051] When the present invention is in use: first, start the timing retractor 33 and let it shrink, so that the insertion plate 341 connected to its expansion end will move downward, and then the water inlet hole 343 opened on the surface of the insertion plate 341 will be connected to the water inlet pipe 347. At this time, the timing retractor 33 will stop and start timing. At the same time, water will enter the interior of the inlet pipe 31 through the water inlet pipe 347 from the external water inlet device connected to the water inlet pipe 347, and the bottom of the inlet pipe 31 is connected to the retention pipe 1, so the water flow will quickly clean the retention pipe 1 and the inlet pipe 31, and finally the water will flow out from the inner perforation 432 opened on the surface of the bottom sliding column 431.

[0052] Then, when the timing retractor 33 finishes timing, it will continue to start and retract, and then the interpenetrating plate 341 connected thereto will continue to move downward, and at the same time, the external water inlet will be removed from the water inlet pipe 347. Therefore, when the timing retractor 33 is retracted to the shortest length, the liquid inlet hole 342 provided on the surface of the interpenetrating plate 341 will be connected to the liquid inlet pipe 348, and then the external liquid inlet connected to the liquid inlet pipe 348 will have the leather base fabric dyeing liquid enter through the liquid inlet pipe 348. Into the inlet pipe 31, it is supplemented that the inner side of the insertion plate 341 is connected to the folding rod 345, so the top rod 351 connected to the other end of the folding rod 345 will move downward with the insertion plate 352, wherein the interior of the insertion plate 352 is fixedly connected with the filter screen 353. Therefore, when the insertion plate 341 moves downward and the liquid inlet hole 342 is connected to the liquid inlet pipe 348, the filter screen 353 will extend into the interior of the inlet pipe 31 and filter the impurities in the leather-based fabric dyeing liquid.

[0053] When the insertion plate 341 moves downward, the folding rod 345 connected to the inner side thereof is connected to the square pressure frame 346, so the compensation cross bar 434 fixedly connected to the bottom of the square pressure frame 346 will move downward accordingly, and the outer side of the compensation cross bar 434 is also connected to the insertion rod 433, and the outer side of the insertion rod 433 is connected to the bottom sliding column 431, so the bottom sliding column 431 will extend downward along the bottom of the inner cavity of the retention tube 1, but the downward sliding of the bottom sliding column 431 will be divided into three stages. The first stage is when the water inlet hole 343 is connected to the water inlet pipe 347, the bottom sliding column 431 will slide downward accordingly, but the top of the inner perforation 432 opened on its surface is still inside the retention tube 1, so water will pass through the inner perforation 432. 32 flows outward, the second stage is when the liquid inlet hole 342 is in the process of being fully connected with the liquid inlet pipe 348, the bottom sliding column 431 will continue to slide downward, and at the same time the inner perforation 432 will be completely outside the retention tube 1, and the hole groove 436 opened on the surface of the bottom sliding column 431 will be partially inside the retention tube 1, and the other half will be outside the retention tube 1. Therefore, part of the leather-based fabric dyeing liquid flowing out of the liquid inlet pipe 348 will pass through the inlet pipe 31 and the retention tube 1 in turn, and finally flow out from the hole groove 436 and enter the sample tube 435. The third stage is when the liquid inlet hole 342 is fully connected with the liquid inlet pipe 348, the top of the bottom sliding column 431 will be completely blocked at the bottom of the retention tube 1, so that the leather-based fabric dyeing liquid cannot flow out and accumulates inside it.

[0054] Supplement: The length of the bottom slide 431 is almost the same as the length of the telescopic end of the timing telescope 33.

[0055] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Various changes made by ordinary technicians in this field based on the above concepts without creative work fall within the scope of protection of the present invention.
