Description

Technical Field

[0001] The utility model relates to the field of chemical engineering, in particular to a sampling device for chemical engineering. Background Technique

[0002] In the field of chemical engineering, it is often necessary to chemically sample chemical reagents, solutions, etc., extract samples from the overall population for testing the overall population. During the sampling process, it is necessary to suck and store the samples for detection and analysis. The sampling device is an indispensable instrument in chemical engineering.

[0003] There are still certain deficiencies in the traditional sampling device for chemical engineering during use: when sampling the liquid inside a chemical bucket, generally an opener is first used to open the lid, and then a sampling rod is used to extend into the bucket to extract the liquid, and then the liquid is injected into a sampling bottle. Since some chemical buckets are relatively tall, and when sampling, it is necessary to layer-sample the liquid with stratification or precipitation, which makes the sampling rod relatively long. When the tester operates, the arm often needs to be stretched very high, which is tiring to operate, and it is easy to stir the liquid in the bucket or cause the sampling rod tube wall to collide with the bucket mouth during the sampling process, resulting in sampling failure and other situations.

[0004] Therefore, it is necessary to provide a new sampling device for chemical engineering to solve the above technical problems. Content of the Utility Model

[0005] The technical problem solved by the utility model is to provide a sampling device for chemical engineering that is convenient for users to sample the liquid in a chemical bucket.

[0006] To solve the above technical problems, a sampling device for chemical engineering provided by the utility model includes: a sampling assembly, the sampling assembly includes a base, a plurality of suction cups are fixedly connected to the bottom of the base, a second bevel gear is rotatably connected to one side position of the top of the base, a first bevel gear is engaged with one side position of the second bevel gear, a lead screw is fixedly connected to the top of the second bevel gear, and a movable member is threadedly connected to the surface of the lead screw;

[0007] A rotating arm is rotatably connected to the surface of the movable member, a fixed sleeve is fixedly connected to the end of the rotating arm, a sampling tube is arranged inside the fixed sleeve, a bracket is fixedly connected to the surface of one side wall of the base, a cylinder body is fixedly connected to the top of the bracket, the bottom of the sampling tube is of an open structure, a piston is slidably connected to the inside of the cylinder body, a push rod is fixedly connected to one side surface of the piston, and the end of the push rod extends to the outside of the cylinder body.

[0008] As a further solution of the present utility model, a fixing frame is fixedly connected to the surface of one side wall of the base, a limiting member is fixedly connected to the top of the fixing frame, and the top of the limiting member is of an open structure.

[0009] Through the above technical solution, after the user extracts the liquid and reverses the crank, the sampling tube is driven to rise by the movable member. During this process, the outer wall of the sampling tube immersed in the liquid will contact the surface of the cleaning pad in the annular member, thereby wiping off this part of the liquid and preventing it from dripping randomly onto the outer area of the bucket during movement. Then, the sampling bottle is placed inside the limiting member and the rotating arm is rotated to move the bottom of the sampling tube to the upper side of the sampling bottle, and the push rod is pushed to inject the liquid in the sampling tube into it by the piston, completing the sampling work. This structural design can prevent the liquid in the chemical bucket from dripping into the external environment, and at the same time, it is convenient to extract, making it more convenient for the staff to operate.

[0010] As a further solution of the present utility model, a positioning rod is fixedly connected to the upper surface of the base on one side of the lead screw. A fixing block is fixedly connected to the top of the positioning rod. The fixing block is rotatably connected between the top of the lead screw, and the movable member is slidably connected to the positioning rod.

[0011] Through the above technical solution, since some chemical buckets are relatively high, and when sampling, it is necessary to perform stratified sampling on liquids with stratification or precipitation, which makes the sampling rod relatively long. When the tester operates, the arm often needs to be stretched very high, which is tiring to operate, and it is easy to stir the liquid in the bucket or cause the sampling rod tube wall to collide with the bucket mouth during the sampling process, resulting in sampling failure and other situations. Therefore, the device is specifically designed with a sampling component. When in use, the base is fixed to one side position of the bucket mouth by using a suction cup, so that the sampling tube is located above the bucket mouth. Then, the crank is rotated, and the lead screw is driven to rotate through the meshing of the first bevel gear and the second bevel gear, so that the movable member moves down. Compared with manual operation, the sampling tube can stably perform the lifting work, and at the same time, it helps the user to extract liquids at different depths, which is convenient and easy to extract, and the design is user-friendly.

[0012] As a further solution of the present utility model, a locking bolt is threadedly connected to the surface of one side wall of the fixing sleeve, and the end of the locking bolt extends into the interior of the fixing sleeve and abuts against the side wall of the sampling tube.

[0013] Through the above technical solution, the sampling tube is fixed inside the fixing sleeve by the locking bolt. When the user needs to replace the sampling tube or clean it, it can be taken out by reversing the locking bolt.

[0014] As a further solution of the present utility model, a support member is fixedly connected to the surface of the side wall of the base on one side of the first bevel gear. An annular member is fixedly connected to the end of the support member, and a cleaning pad is fixedly connected to the inner wall of the annular member. The cleaning pad is located below the sampling tube.

[0015] Through the above technical solution, the annular part and the cleaning pad are located on the lower side of the sampling tube. When the sampling tube is taken out, the outer wall thereof contacts the cleaning pad, thereby wiping off the liquid on the surface of the sampling tube and preventing it from dripping onto other areas of the chemical barrel.

[0016] As a further solution of the present utility model, through holes are provided inside the cleaning pad, the diameter of the through holes is the same as the outer diameter of the sampling tube, and a communicating pipe is connected between the end of the cylinder body and the top of the sampling tube.

[0017] Through the above technical solution, the through holes in the cleaning pad facilitate the entry and exit of the sampling tube. The communicating pipe is arranged between the cylinder body and the sampling tube, so that when the user moves the piston, the liquid in the sampling tube can be driven in and out.

[0018] As a further solution of the present utility model, a fixed shaft is fixedly connected to the surface of one side wall of the first bevel gear. The fixed shaft is rotatably connected to the base through a connecting block, and a crank is fixedly connected to the end of the fixed shaft.

[0019] Through the above technical solution, rotating the crank can drive the first bevel gear to rotate, and then drive the lead screw to rotate through the second bevel gear meshing therewith.

[0020] Compared with the related art, a sampling device for chemical engineering provided by the present utility model has the following beneficial effects:

[0021] 1. In the present utility model, since the height of some chemical barrels is relatively high, and during sampling, it is necessary to perform layered sampling on liquids with stratification or precipitation. This makes the sampling rod relatively long. When the tester operates, the arm often needs to be stretched very high, which is tiring to operate. Moreover, during the sampling process, it is easy to stir the liquid in the barrel or cause the tube wall of the sampling rod to collide with the barrel mouth, resulting in sampling failure and other situations. Therefore, the sampling assembly is specially designed for this device. When in use, the base is fixed to one side position of the barrel mouth by using a suction cup, so that the sampling tube is located above the barrel mouth. Then, the crank is rotated, and the lead screw is driven to rotate through the meshing of the first bevel gear and the second bevel gear. Then, the moving part moves downward. Compared with manual operation, the sampling tube can perform the lifting work stably, and at the same time, it helps the user to extract liquids at different depths, which is convenient and easy to operate, and the design is user-friendly;

[0022] 2. In the present utility model, after the user extracts the liquid, the user reverses the crank handle, and drives the sampling tube to rise through the movable member. During this process, the outer wall of the sampling tube immersed in the liquid will contact the surface of the cleaning pad in the annular member, thereby wiping off the liquid in this part and preventing it from dripping randomly onto the area outside the bucket during movement. Then, the sampling bottle is placed inside the limiting member and the rotating arm is rotated to move the bottom of the sampling tube to the upper side of the sampling bottle, and the push rod is pushed to enable the piston to inject the liquid in the sampling tube into it, completing the sampling work. The structural design can prevent the liquid in the chemical industrial barrel from dripping into the external environment, and at the same time, the extraction is convenient, making it more convenient for the staff to operate.

[0030] Please refer to Figures 1 to 4 , where Figure 1 Schematic diagram of the overall structure of a sampling device for chemical engineering in the present utility model Figure 1 ; Figure 2 Schematic diagram of the overall structure of a sampling device for chemical engineering in the present utility model Figure 2 ; Figure 3 Schematic diagram of the overall structure of a sampling device for chemical engineering in the present utility modelFigure 3 ; Figure 4 This is a partial structural cross-sectional view of a sampling device for chemical engineering in the present utility model. A sampling device for chemical engineering includes:

[0031] A sampling assembly 1, the sampling assembly 1 includes a base 17, a plurality of suction cups 4 are fixedly connected to the bottom of the base 17, a second bevel gear 16 is rotatably connected to one side position of the top of the base 17, a first bevel gear 13 is engaged with one side position of the second bevel gear 16, a lead screw 2 is fixedly connected to the top of the second bevel gear 16, and a movable member 10 is threadedly connected to the surface of the lead screw 2;

[0032] A rotating arm 11 is rotatably connected to the surface of the movable member 10, a fixing sleeve 19 is fixedly connected to the end of the rotating arm 11, a sampling tube 3 is arranged inside the fixing sleeve 19, a bracket 22 is fixedly connected to the surface of one side wall of the base 17, a cylinder 7 is fixedly connected to the top of the bracket 22, the bottom of the sampling tube 3 is of an open structure, a piston 20 is slidably connected inside the cylinder 7, a push rod 14 is fixedly connected to one side surface of the piston 20, and the end of the push rod 14 extends to the outside of the cylinder 7.

[0033] As Figures 1 - 4 shown, a fixing frame is fixedly connected to the surface of one side wall of the base 17, a limiting member 15 is fixedly connected to the top of the fixing frame, and the top of the limiting member 15 is of an open structure.

[0034] After the user extracts the liquid, the user reverses the crank 21, drives the sampling tube 3 to rise through the movable member 10. During this process, the outer wall of the sampling tube 3 immersed in the liquid will contact the surface of the cleaning pad 12 inside the annular member 6, thereby wiping off this part of the liquid, avoiding it from dripping randomly to the outside area of the bucket during the movement. Then, place the sampling bottle inside the limiting member 15 and rotate the rotating arm 11 to move the bottom of the sampling tube 3 to the upper side of the sampling bottle, and push the push rod to let the piston 20 inject the liquid in the sampling tube 3 into it, completing the sampling work. The structural design can avoid the liquid in the chemical bucket from dripping into the external environment, and at the same time, the extraction is convenient, making it more convenient for the staff to operate.

[0035] As Figures 1 - 4 shown, a positioning rod 9 is fixedly connected to the upper surface of the base 17 on one side of the lead screw 2, a fixing block is fixedly connected to the top of the positioning rod 9, the fixing block is rotatably connected between the top of the lead screw 2, and the movable member 10 is slidably connected to the positioning rod 9.

[0036] Due to the relatively high height of some chemical barrels, and during sampling, it is necessary to perform stratified sampling on liquids with stratification or precipitation. This makes the sampling rod relatively long. When operating, the tester often needs to stretch the arm very high, which is tiring. Moreover, during the sampling process, it is easy to stir the liquid in the barrel or cause the wall of the sampling rod to collide with the barrel mouth, resulting in sampling failure and other situations. Therefore, the device is specifically designed with a sampling component 1. When in use, the base 17 is fixed to one side of the barrel mouth by the suction cup 4, so that the sampling tube 3 is located above the barrel mouth. Then, the crank 21 is rotated, and the rotation of the first bevel gear 13 and the second bevel gear 16 drives the lead screw 2 to rotate, thereby moving the movable part 10 downward. Compared with manual operation, the sampling tube 3 can perform stable lifting work, and it is also helpful for the user to extract liquids at different depths, making the extraction convenient and easy, with a user-friendly design.

[0037] As Figures 1 - 4 shown, a locking bolt 18 is threadedly connected to the surface of one side wall of the fixing sleeve 19, and the end of the locking bolt 18 extends into the interior of the fixing sleeve 19 and abuts against the side wall of the sampling tube 3.

[0038] The sampling tube 3 is fixed inside the fixing sleeve 19 by the locking bolt 18. When the user needs to replace or clean the sampling tube 3, it can be taken out by reversing the locking bolt 18.

[0039] As Figures 1 - 4 shown, a support member 5 is fixedly connected to the surface of the side wall of the base 17 on one side of the first bevel gear 13. The end of the support member 5 is fixedly connected to an annular member 6, and a cleaning pad 12 is fixedly connected to the inner wall of the annular member 6. The cleaning pad 12 is located below the sampling tube 3.

[0040] The annular member 6 and the cleaning pad 12 are located below the sampling tube 3. When the sampling tube 3 is taken out, its outer wall contacts the cleaning pad 12, thereby wiping off the liquid on the surface of the sampling tube 3 to prevent it from dripping onto other areas of the chemical barrel.

[0041] As Figures 1 - 4 shown, a through hole is formed in the interior of the cleaning pad 12, and the diameter of the through hole is the same as the outer diameter of the sampling tube 3. A communication pipe 8 is connected between the end of the cylinder body 7 and the top of the sampling tube 3.

[0042] The through hole on the cleaning pad 12 facilitates the entry and exit of the sampling tube 3. The communication pipe 8 is provided between the cylinder body 7 and the sampling tube 3, enabling the user to drive the liquid in the sampling tube 3 to flow in and out when moving the piston 20.

[0043] As Figures 1 - 4 shown, a fixed shaft is fixedly connected to the surface of one side wall of the first bevel gear 13. The fixed shaft is rotationally connected to the base 17 through a connecting block, and a crank 21 is fixedly connected to the end of the fixed shaft.

[0044] By rotating the crank 21, the first bevel gear 13 can be driven to rotate, and then the lead screw 2 can be driven to rotate by the second bevel gear 16 meshed with it.

[0045] The working principle of a sampling device for chemical engineering provided by the present utility model is as follows:

[0046] The first step: Since the height of some chemical barrels is relatively high, and during sampling, it is necessary to perform layered sampling on liquids with stratification or precipitation. This makes the sampling rod relatively long. When the tester operates, the arm often needs to be stretched very high, which is tiring to operate. Moreover, during the sampling process, it is easy to stir the liquid in the barrel or cause the outer wall of the sampling rod to collide with the barrel mouth, resulting in sampling failure and other situations. Therefore, the sampling assembly 1 is specially designed for this device. When in use, the base 17 is fixed to one side of the barrel mouth by the suction cup 4, so that the sampling tube 3 is located above the barrel mouth. Then, the crank 21 is rotated, and the lead screw 2 is driven to rotate through the meshing of the first bevel gear 13 and the second bevel gear 16. Then, the moving part 10 moves downward. Compared with manual operation, the sampling tube 3 can perform stable lifting work, and at the same time, it helps the user to extract liquids at different depths, which is convenient and easy to extract, and the design is user-friendly;

[0047] The second step: After the user extracts the liquid, the crank 21 is rotated in reverse, and the sampling tube 3 is driven to rise by the moving part 10. During this process, the outer wall of the sampling tube 3 immersed in the liquid will contact the surface of the cleaning pad 12 in the annular part 6, and then wipe off this part of the liquid to prevent it from dripping randomly outside the barrel during the movement. Then, the sampling bottle is placed inside the limiting part 15 and the rotating arm 11 is rotated, so that the bottom of the sampling tube 3 moves to the upper side of the sampling bottle, and the push rod is pushed, so that the piston 20 injects the liquid in the sampling tube 3 into it, completing the sampling work. This structural design can prevent the liquid in the chemical barrel from dripping into the external environment, and at the same time, it is convenient to extract, making it more convenient for the staff to operate.
