Description

Technical Field

[0001] The utility model relates to the chemical industry field, in particular to a chemical intermediate sampling pipeline. Background Technique

[0002] Chemical pipelines are usually used for transporting chemical raw materials. In the production of chemical products, it is often necessary to sample and detect the chemical raw materials in the chemical pipeline. Usually, a chemical intermediate sampling pipeline is required. The chemical intermediate sampling pipeline is usually installed on the chemical pipeline to sample without affecting the normal transportation of the chemical raw materials in the chemical pipeline.

[0003] Traditional chemical intermediate sampling pipelines usually need to sample multiple times to ensure the sampling accuracy. Moreover, the chemical raw materials may be stratified during transportation, which may affect the sampling and detection results of the chemical raw materials. It is not convenient to extract the chemical raw materials at different positions in the chemical pipeline, which may lead to a large sampling error of the chemical raw material samples, thus affecting the sampling accuracy of the chemical raw materials. In addition, multiple samplings affect the sampling efficiency of the chemical raw materials. Content of the Utility Model

[0004] In order to overcome the above-mentioned disadvantages in the background technique, the utility model provides a chemical intermediate sampling pipeline, which reduces the sampling error of the sample, improves the sampling accuracy of the sampled sample, and is beneficial to improving the sampling efficiency of the sampled sample.

[0005] The technical solution of the utility model is as follows: a chemical intermediate sampling pipeline includes an installation pipe, an installation frame, a rotating disk, a lead screw, a nut, a connecting plate and a material taking pipe. The installation pipe is installed on the conveying pipe. One side of the installation pipe is fixedly connected with the installation frame. The rotating disk is rotatably connected to the installation frame. The bottom of the rotating disk is fixedly connected with the lead screw. The lead screw is rotatably connected to the installation frame. The nut is connected to the lead screw through a thread. The connecting plate is slidably connected to the installation frame. One end of the connecting plate is fixedly connected with the nut. The end of the connecting plate far from the nut is fixedly connected with the material taking pipe. The material taking pipe contacts the installation pipe.

[0006] In one of the embodiments, a material taking port is opened at the bottom of the installation pipe. The material taking pipe is located at the material taking port of the installation pipe. An inlet port is opened on one side of the upper part of the material taking pipe, and an outlet port is opened on the other side of the lower part of the material taking pipe.

[0007] In one of the embodiments, it includes a discharge frame and a sample pipe. The bottom of the installation pipe is fixedly connected with the discharge frame. Three material holes are opened on one side of the discharge frame close to the material taking pipe. Three installation ports are opened at the lower part of the discharge frame. The three installation ports of the discharge frame are all connected with the sample pipe through a thread. The sample pipe is used to collect the sample taken out by the material taking pipe.

[0008] In one embodiment, it includes a movable plate, a support spring, a bump, a limit block, a movable rod and a connecting rod. A movable plate is slidably connected to the material taking pipe. Two support springs are connected between the movable plate and the material taking pipe. Three bumps are installed on the discharge rack, and the three bumps are respectively at the same height as the three material holes of the discharge rack. A limit block is installed on one side of the material taking pipe close to the bump. A movable rod is slidably connected to the limit block. One end of the movable rod is rotatably connected to one end of the connecting rod, and the other end of the connecting rod is rotatably connected to the movable plate.

[0009] In one embodiment, the movable plate is located on the side of the feed inlet of the material taking pipe, and the movable plate is used to intermittently open the feed inlet of the material taking pipe.

[0010] The beneficial effects are as follows: The feed inlet of the material taking pipe enters the installation pipe, and the chemical raw materials flowing at different heights in the installation pipe enter different sample pipes. By sampling the chemical raw materials at different heights, the sampling accuracy of the sampled samples is improved, which is beneficial to improving the sampling efficiency of the sampled samples.

[0011] The bump pushes the movable rod to move horizontally, and through the connecting rod, the movable plate is pushed to move downward, and the feed inlet of the material taking pipe is opened. The movable plate moves upward to reset and block the feed inlet of the material taking pipe. By intermittently opening the feed inlet of the material taking pipe through the movable plate, the material taking pipe can more accurately obtain chemical raw material samples at different positions, reduce the sampling error of the samples, and further improve the sampling accuracy of the sampled samples.

Detailed Embodiments

[0018] The technical solution of the present utility model will be further described below in conjunction with the accompanying drawings.

[0019] Example 1: A chemical intermediate sampling pipeline, as Figures 1-5 shown, includes an installation pipe 1, an installation frame 3, a rotating disk 4, a lead screw 5, a nut 6, a connecting plate 7 and a sampling pipe 8. The installation pipe 1 is installed on the conveying pipe 2 through bolts. One side of the installation pipe 1 is connected to the installation frame 3 through bolts. The rotating disk 4 is rotatably connected to the installation frame 3 through a bearing. The bottom of the rotating disk 4 is welded with the lead screw 5. The lead screw 5 is rotatably connected to the installation frame 3. The nut 6 is threadedly connected to the lead screw 5. The connecting plate 7 is slidably connected to the installation frame 3. One end of the connecting plate 7 is fixed to the nut 6. The end of the connecting plate 7 away from the nut 6 is connected to the sampling pipe 8 through bolts. The sampling pipe 8 is in contact with the installation pipe 1.

[0020] A sampling port is opened at the bottom of the installation pipe 1. The sampling pipe 8 is located at the sampling port of the installation pipe 1. An inlet port is opened on one side of the upper part of the sampling pipe 8, and an outlet port is opened on the other side of the lower part of the sampling pipe 8.

[0021] It includes a discharge rack 9 and a sample tube 10. The bottom of the installation pipe 1 is fixedly connected to the discharge rack 9. Three material holes are opened on one side of the discharge rack 9 close to the sampling pipe 8. Three installation ports are opened at the lower part of the discharge rack 9. The three installation ports of the discharge rack 9 are all threadedly connected with the sample tube 10. The sample tube 10 is used to collect the samples taken out by the sampling pipe 8.

[0022] First, the operator installs the installation pipe 1 on the conveyor. The conveying pipe 2 conveys chemical raw materials. During sampling, the operator turns the rotating disk 4 and the lead screw 5 rotate together. The rotating lead screw 5 drives the nut 6 to move upward through the thread. The connecting plate 7 and the sampling pipe 8 move upward together. The inlet port of the sampling pipe 8 enters the installation pipe 1. The chemical raw materials flowing in the lower part of the installation pipe 1 enter the sampling pipe 8. The chemical raw materials enter the lowest material hole of the discharge rack 9 through the outlet port of the sampling pipe 8, and then enter the lowest sample tube 10. The sampling pipe 8 continues to move upward. The chemical raw materials in the middle part of the installation pipe 1 enter the middle sample tube 10. Subsequently, the sampling pipe 8 continues to move upward. The chemical raw materials in the upper part of the installation pipe 1 enter the upper sample tube 10. By sampling the chemical raw materials at different heights, the sampling accuracy of the sampling samples is improved, which is beneficial to improving the sampling efficiency of the sampling samples. The operator reversely turns the rotating disk 4 and the lead screw 5, and the nut 6, the connecting plate 7 and the sampling pipe 8 move reversely and reset. Finally, the operator removes the sample tube 10.

[0023] Example 2: On the basis of Example 1, as Figures 3-5As shown in the figure, it includes a movable plate 11, a support spring 12, a convex block 13, a limit block 14, a movable rod 15 and a connecting rod 16. A movable plate 11 is slidably connected to the material taking pipe 8. Two support springs 12 are connected between the movable plate 11 and the material taking pipe 8. Three convex blocks 13 are installed on the discharging rack 9 by bolts. The three convex blocks 13 are respectively at the same height as the three material holes of the discharging rack 9. The convex block 13 is used to push the movable rod 15. A limit block 14 is installed on the material taking pipe 8 near the convex block 13 by bolts. The movable rod 15 is slidably connected to the limit block 14. One end of the movable rod 15 is rotatably connected to one end of the connecting rod 16. The other end of the connecting rod 16 is rotatably connected to the movable plate 11.

[0024] The movable plate 11 is located on the side of the feeding port of the material taking pipe 8, and the movable plate 11 is used to intermittently open the feeding port of the material taking pipe 8.

[0025] The material taking pipe 8 drives the limit block 14, the movable rod 15, the connecting rod 16, the movable plate 11 and the support spring 12 to move upward together. The movable rod 15 moves to contact the convex block 13. The convex block 13 pushes the movable rod 15 to move horizontally. The movable plate 11 is pushed to move downward through the connecting rod 16. The support spring 12 is stretched. The feeding port of the material taking pipe 8 is opened. The movable rod 15 is separated from the convex block 13. The support spring 12 pulls the movable plate 11 to move upward and reset. The connecting rod 16 and the movable rod 15 are reset accordingly. This process is repeated three times. By intermittently opening the feeding port of the material taking pipe 8 through the movable plate 11, the material taking pipe 8 can more accurately take chemical raw material samples at different positions, reduce the sampling error of the samples, and further improve the sampling accuracy of the sampled samples.
