Description

[0003] For example, in the prior art, there is an automatic sampler for organic peroxide production with a publication number of CN219757798U. Although the automatic sampler can avoid the problem that the traditional sampler cannot sample at different levels in the reactor, which requires personnel to enter the dangerous area for sampling, each time sampling is performed, only a single layer of samples can be sampled and collected. When sampling multiple layers of samples, the sampling operation cannot be completed synchronously, and it is difficult to further improve the sampling efficiency of multi-layer peroxide samples.

[0004] In view of the above technical defects, a solution is now proposed. Utility Model Content

The utility model can extract and collect peroxides at different levels at the same time by detachably installing multiple sampling barrels at different positions on a mounting column. Compared with the method of collecting only a single layer of samples at a time in the prior art, the sampling efficiency of multi-layer peroxide samples can be effectively improved; and the sampling barrel can be directly used to store samples, avoiding the problem of inaccurate inspection results caused by mixing samples of different levels when multiple samplings are performed.

[0006] This is achieved through the following technical solutions:

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The problem that only a single layer of samples can be sampled and collected at a time in the prior art and multi-layer sample collection cannot be completed synchronously can be solved by the following solution;

[0029] See also Figure 1 - Figure 6 As shown, an automatic sampling device for peroxide production inspection includes a mounting column 1, and a plurality of sampling barrels 2 are mounted on the outer wall of the mounting column 1 along its length direction. When sampling, the mounting column 1 is vertically placed in a peroxide solution, and a plurality of sampling barrels 2 at different positions are arranged on the outer side thereof, so that peroxides at different layers can be extracted and collected at the same time. Compared with the method in the prior art that only a single layer of samples can be collected each time, the sampling efficiency of multi-layer peroxide samples can be effectively improved;

[0030] A connecting tube 21 is fixedly connected to the bottom of one side of the sampling tube 2 for extracting and discharging the peroxide sample. A piston block 22 is slidably connected to the inside of the sampling tube 2. A movable rod 23 slidably connected to the sampling tube 2 is fixedly connected to the top of one side of the piston block 2. The piston block 22 is driven to move upward in the sampling tube 2 by the movable rod 23 and cooperates with the connecting tube 21 to collect and sample the sample. The piston block 22 is driven to move downward in the sampling tube 2 by the movable rod 23 and cooperates with the connecting tube 21 to remove the sample.

[0031] A movable groove 11 is provided on the outer wall of one side of the mounting column 1, and a movable column 12 is slidably connected in the movable groove 11 to cooperate with a movable rod 23 to drive the piston block 22 to move. Limiting grooves are provided on the inner walls on both sides of the movable groove 11, and limiting blocks adapted to the corresponding limiting grooves are fixedly connected on the outer side wall of the movable column 12, thereby ensuring the stable sliding installation of the movable column 12 in the movable groove 11. A screw rod 13 threadedly connected to the movable column 12 is rotatably connected to the top of the movable groove 11, and a motor 14 for driving the screw rod 13 to rotate is installed on the top bolt of the mounting column 1. The screw rod 13 is driven to rotate by the motor 14, and the screw rod 13 drives the movable column 12 to rise in the movable groove 11. The movable column 12 cooperates with the corresponding movable rod 23 to drive multiple piston blocks 22 to move synchronously, thereby realizing the synchronous collection of multi-layer peroxide samples, thereby improving the collection efficiency.

[0032] A sliding card slot 15 is provided inside the mounting column 1 and runs through the bottom thereof, and a plurality of fixing holes 16 are provided on the inner wall of one side of the sliding card slot 15 at equal intervals along the length direction thereof, and a fixing card block 24 is fixedly connected to the sampling tube 2 and is slidably connected to the sliding card slot 15. The sliding card slot 15 runs through the bottom of the mounting column 1, so that the sampling tube 2 and the mounting column 1 can be disassembled and separated, so that the sampling tube 2 can be directly used to store the peroxide sample, so that the problem of inaccurate test results caused by the mixing of samples at different levels when multiple samplings are performed can be avoided, and the number of sampling tubes 2 can be controlled according to the samples at the required number of levels, so that the remaining sampling tubes 2 can be contaminated with samples at unnecessary levels, so that the sampling tubes 2 cannot be directly used;

[0033] A fixing pin 25 matched with the fixing hole 16 is provided on the fixing block 24. The fixing pin 25 on the fixing block 24 cooperates with the fixing holes 16 at different heights to achieve adjustment of the positions of multiple sampling tubes 2, thereby facilitating sampling of peroxide samples at different heights according to actual inspection needs, thereby further improving the scope of use of the device.

[0034] A groove 26 is provided on the fixed block 24 on one side away from the movable rod 23, and a movable plate 27 fixedly connected to the fixed pin 25 is slidably connected in the groove 26, and a screw 28 threadedly connected to the movable plate 27 is rotatably connected in the groove 26. When the position adjustment of the sampling tube 2 is completed, the movable plate 27 is driven to slide in the groove 26 by rotating the screw 28, so that the fixed pin 25 on the movable plate 27 is inserted into the fixed hole 16 at the corresponding position, that is, the position of the sampling tube 2 is fixed, and a yield groove 17 connected to the sliding groove 15 is provided on the outer side wall of the mounting column 1, which is used to extend the free end of the screw 28 to the outside of the mounting column 1, thereby facilitating the rotation of the screw 28. The free end of the screw 28 extends to the outside of the mounting column 1 through the yield groove 17 and is fixedly connected to a torsion wheel 29.

[0035] The top of the movable rod 23 penetrates the outside of the sampling tube 2 and is rotatably connected with a screw rod 210. A plurality of fixing holes 18 that are compatible with the screw rod 210 are equidistantly provided on the outer wall of one side of the movable column 12 along its length direction. Through the cooperation between the screw rod 210 and the fixing hole 18, the connection between the movable column 12 and the movable rod 23 can be completed when the sampling tube 2 is in different positions, thereby not affecting the sampling of the peroxide sample. A fixing hole 3 211 that is compatible with the screw rod 210 is provided on the top of one side of the fixed block 24 close to the movable rod 23. When the sampling tube 2 is removed from the mounting column 1, when the peroxide sample is stored in the sampling tube 2, the movement of the piston block 22 in the sampling tube 2 can be limited by the insertion of the screw rod 210 and the fixing hole 3 211, thereby ensuring that the sample discharge problem will not occur due to misoperation of the movable rod 23 during the transportation of the sampling tube 2. One end of the screw rod 210 is fixedly connected with a torsion wheel 212.

[0036] The interior of the connecting tube 21 is rotatably connected to a sealing ball 213 via a rotating shaft, and a connecting hole 214 is penetrated by the sealing ball 213. One end of the rotating shaft penetrates to the outside of the connecting tube 21 and is fixedly connected to a gear 215. When sampling is completed, the sealing ball 213 is driven to rotate in the connecting tube 21 by rotating the gear 215 to achieve sealing of the connecting hole 214, which can further avoid the problem of leakage of the peroxide sample.

[0037] An L-shaped rod 216 is fixedly connected to the movable rod 23, and a toothed plate 217 matched with the gear 215 is fixedly connected to the bottom of one side of the L-shaped rod 216. When the movable rod 23 drives the piston block 22 to move to sample the peroxide, the movable rod 23 drives the L-shaped rod 216 to move synchronously. When the sampling is about to be completed, the toothed plate 217 on the L-shaped rod 216 engages with the gear 215, forcing the sealing ball 213 in the connecting pipe 21 to rotate, thereby realizing automatic sealing of the connecting pipe 21.

[0038] The working process and principle of the utility model are as follows:

[0039] During use, the utility model places the mounting column 1 vertically in the peroxide solution, drives the screw rod 13 to rotate through the motor 14, drives the moving column 12 to move upward in the movable groove 11, and the moving column 12 cooperates with the corresponding screw rod 210 and the movable rod 23 to drive the multiple piston blocks 22 to move upward synchronously in the sampling tube 2, and extracts the peroxide samples at different levels synchronously through the connecting tube 21;

[0040] The movable rod 23 drives the piston block 22 to move to sample the peroxide, and the movable rod 23 drives the L-shaped rod 216 to move synchronously. When the sampling is about to be completed, the toothed plate 217 on the L-shaped rod 216 meshes with the gear 215, and the rising toothed plate 217 drives the gear 215 to rotate. The gear 215 drives the sealing ball 213 to rotate in the connecting pipe 21, and the connecting hole 214 is blocked, and the connecting pipe 21 is automatically blocked.

[0041] After sampling, the second twist wheel 212 is rotated to drive the second screw rod 210 to separate from the second fixing hole 18, and the twist wheel 1 29 is rotated to drive the screw rod 28 to rotate. The rotation of the screw rod 28 drives the movable plate 27 to slide in the groove 26, so that the fixing pin 25 on the movable plate 27 is separated from the fixing hole 16 at the corresponding position, so that the sampling tube 2 can be removed from the mounting column 1. After removal, the second twist wheel 212 is rotated to drive the second screw rod 210 to be plugged into the fixing hole 3 211, so as to prevent the sampling tube 2 from being discharged due to misoperation of the movable rod 23 during transportation, and by means of the plugging of the fixing pin 25 on the movable plate 27 with the fixing hole 16 at different positions, and the plugging of the second screw rod 210 with the fixing hole 18 at the corresponding position, the peroxide samples of different heights can be sampled according to the actual inspection needs.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
