Abstract
Description
Technical Field
[0001] This utility model relates to the field of sampling device technology, and in particular to a sampling device for a solution mixing tank. Background Technology
[0002] In the production of chemical products, mixing equipment, such as mixing tanks, is most commonly used. This is because the production of chemical products requires the addition of various liquid chemical solutions to the mixing tank for stirring, thus mixing the different solutions together. Different chemical products require different types of raw materials for production, generally requiring the mixing of two or more different raw materials in specific proportions. However, in modern mixing tanks, after the various chemical solutions are mixed, workers drain a certain amount of solution through the drain pipe on the mixing tank for sampling and testing. But the drain pipe on the mixing tank can only drain the solution located at the bottom of the tank; it cannot sample and test solutions in other parts of the tank. This results in highly limited and inaccurate test results, and may even lead to substandard quality in the subsequent production of chemical products. Utility Model Content
[0003] This utility model discloses a sampling device for a solution mixing tank, which solves the problem that it can only sample and test the solution at the bottom of the mixing tank, and cannot sample the solution in other parts of the tank, resulting in great limitations and inaccuracies in the test results.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] A sampling device for a solution mixing tank includes a tank body. A connecting cylinder is located near the bottom of the tank body. The bottom of the connecting cylinder is connected to a first folded tube, and the bottom of the first folded tube is connected to a fixed cylinder fixed to the bottom of the tank body. A perforation corresponding to the bottom of the fixed cylinder is formed at the bottom of the tank body. A connecting pipe is fixed inside the connecting cylinder, with one end penetrating the connecting cylinder. A solenoid valve is connected to the end of the connecting pipe outside the connecting cylinder. A sampling pipe is connected to the inlet end of the solenoid valve. A second folded tube extending out of the perforation is connected to the end of the connecting pipe away from the solenoid valve. Support legs are fixed to the bottom of the tank body, and a fixed plate is fixed to the support legs. An electric telescopic rod for driving the connecting cylinder to rise and fall is fixed to the fixed plate. A stirring assembly intersecting the connecting cylinder is located inside the tank body.
[0006] Compared with the prior art, the present invention has the following beneficial effects:
[0007] After adding various chemical solutions into the tank, the stirring assembly is activated to mix the solutions. Once the mixture is complete, the solenoid valve is opened, allowing the solution in the tank to enter the connecting pipe through the sampling pipe. The solenoid valve is then closed, and the solution can be discharged through the second folded pipe, completing the sampling of the solution near the bottom of the tank. When sampling solutions at different heights within the tank is required, the electric telescopic rod is activated to move the connecting cylinder upwards, stretching the first folded pipe. Simultaneously, the bottom end of the second folded pipe can be fixed, causing it to stretch as well. Once the sampling pipe reaches the designated height, the solenoid valve is opened to complete the sampling of solutions at different heights within the tank. This invention allows for sampling and testing of solutions at different heights within a mixing tank. The operation is simple, improves the accuracy of the test results, and facilitates a thorough understanding of the uniformity of the mixing of various solutions within the tank.

[0015] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.
[0016] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this utility model provides a sampling device for a solution mixing tank, including a tank body 1. A connecting cylinder 2 is provided inside the tank body 1 near the bottom of the tank body 1. The bottom of the connecting cylinder 2 is connected to a first folded tube 21. The bottom of the first folded tube 21 is connected to a fixed cylinder 22 fixed inside the bottom of the tank body 1. A through hole 3 corresponding to the bottom of the fixed cylinder 22 is opened at the bottom of the tank body 1. A connecting pipe 4 is fixed inside the connecting cylinder 2, with one end penetrating the connecting cylinder 2. The end of the connecting pipe 4 outside the connecting cylinder 2 is connected to a solenoid valve 41. The feed end of the solenoid valve 41 is connected to a sampling pipe 42. The end of the connecting pipe 4 away from the solenoid valve 41 is connected to a second folded tube 43 extending to the outside of the through hole 3. A support leg 5 is fixed at the bottom of the tank body 1. A fixing plate 51 is fixed on the support leg 5. An electric telescopic rod 52 for driving the connecting cylinder 2 to rise and fall is fixed on the fixing plate 51. A stirring assembly intersecting with the connecting cylinder 2 is provided inside the tank body 1.
[0017] like Figure 1 and Figure 2 As shown, the stirring assembly includes a rotating rod 6 that passes through the top of the tank 1 and is rotatably connected to the tank 1. Two stirring blades 61 that are located inside the tank 1 and are symmetrically arranged are fixed on the rotating rod 6. Blades 62 are fixed on the stirring blades 61. A motor 64 is fixed on the top of the tank 1. The rotating shaft of the motor 64 is fixed to one end of the rotating rod 6 located outside the tank 1. The connecting cylinder 2 is located between the two stirring blades 61. After starting the motor 64, the shaft of the motor 64 can drive the two stirring blades 61 to rotate via the rotating rod 6. The stirring blades 61 (arranged in an L-shape) contact the inner wall of the tank 1, scraping off the raw materials adhering to the inner wall of the tank 1 and facilitating subsequent cleaning of the inner wall of the tank 1. A set of blades 62 is provided on the stirring blades 61, which can fully stir the solution in the tank 1, allowing the various solutions in the tank 1 to be evenly mixed. When not in use, the connecting cylinder 2 is located below the two sets of blades 62, preventing the material pick-up pipe 42 from affecting the normal movement of the blades 62. When the connecting cylinder 2 needs to be raised or lowered, the stirring blades 61 can be rotated so that the two stirring blades 61 contact the front and back sides of the tank 1 respectively (to...). Figure 1 (As shown in the diagram), when the connecting cylinder 2 is moved upward, the connecting cylinder 2 is located between the two sets of blades 62, and the material taking tube 42 is also located between the two sets of blades 62. The blades 62 will not affect the normal lifting and sampling work of the material taking tube 42.
[0018] like Figure 1As shown, an arc-shaped plate 63 is fixed to the bottom of the stirring blade 61, and the arc-shaped plate 63 is in contact with the bottom surface of the tank 1. The fixing cylinder 22 is located between the two arc-shaped plates 63. The top and bottom of the tank 1 are respectively connected to the feed pipe 7 and the discharge pipe 8. The arc-shaped plate 63 can stir the solution located at the bottom of the tank 1, so that the solution at the bottom of the tank 1 can also be fully stirred and mixed. The operator can transport the solution into the tank 1 through the feed pipe 7, and after the solution is stirred, it can be discharged through the discharge pipe 8.
[0019] like Figure 1 , Figure 4 and Figure 5 As shown, the bottom of the second folded tube 43 is connected to a fixed tube 44 that passes through the fixed plate 51, and the bottom of the fixed tube 44 is threadedly connected to a sampling cup 45. When the solution in the tank 1 enters the second folded tube 43, the solution can enter the sampling cup 45 through the fixed tube 44. The sampling cup 45 is equipped with a scale value so that the staff can know the amount of solution loaded in the sampling cup 45; and when the connecting cylinder 2 moves upward to stretch the first folded tube 21, the staff does not need to manually fix the second folded tube 43, reducing the workload of the staff.
[0020] like Figure 1 and Figure 4 As shown, a cleaning pipe 46 located on the fixed plate 51 is connected to the fixed pipe 44, and a valve 47 is installed on the cleaning pipe 46 near the fixed pipe 44. The end of the cleaning pipe 46 away from the fixed pipe 44 is connected to an external water source. After each sample of the solution in the tank 1 is taken, the solenoid valve 41 can be closed and the valve 47 can be opened to allow the external water source to enter the cleaning pipe 46. The water then enters the fixed pipe 44, the second folded pipe 43, and the connecting pipe 4 to clean the inside of the fixed pipe 44, the second folded pipe 43, and the connecting pipe 4. During cleaning, the operator can use an external sealing plug to seal the bottom of the fixed pipe 44, and then remove the external sealing plug afterwards.
[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, a protective tube 48 covering the solenoid valve 41 is fixed on the connecting cylinder 2. A storage battery 24 is fixed at the top inside the connecting cylinder 2. A sealing ring 23 is fitted on the fixed cylinder 22 and is fixedly connected to the bottom inside the tank body 1. The protective tube 48 covers the part of the connecting pipe 4 outside the connecting cylinder 2 and the solenoid valve 41. The end of the material receiving pipe 42 away from the solenoid valve 41 passes through the protective tube 48. The protective tube 48 can effectively protect the solenoid valve 41 and prevent it from being immersed in the chemical solution. The storage battery 24 can supply power to the solenoid valve 41. The sealing ring 23 can increase the tightness of the connection between the fixed cylinder 22 and the tank body 1. The perforation 3 at the bottom of the tank body 1 is located directly below the fixed cylinder 22.
[0022] like Figure 1 , Figure 2 and Figure 5 As shown, there are two connecting pipes 4, arranged side to side. The length of one connecting pipe 4 outside the connecting cylinder 2 is greater than the length of the other connecting pipe 4 outside the connecting cylinder 2. The telescopic end of the electric telescopic rod 52 is fixed with a connecting block 53 located inside the connecting cylinder 2. The connecting block 53 is connected to the two connecting pipes 4 respectively. The connecting cylinder 2 is located at the axis of the tank 1. The arrangement of the two connecting pipes 4, one long and one short, allows the sampling pipe 42 on the solenoid valve 41 connected to the short connecting pipe 4 to sample the solution near the axis of the tank 1, while the sampling pipe 42 on the solenoid valve 41 connected to the long connecting pipe 4 can sample the solution away from the axis of the tank 1. This further expands the sampling range inside the tank 1 and improves the accuracy of the solution sampling and testing results. After the electric telescopic rod 52 is activated, the telescopic end of the electric telescopic rod 52 can drive the connecting block 53 to move upward. The connecting block 53 can then drive the connecting cylinder 2 to move upward through the connecting pipe 4, stretching the first folded tube 21.
[0023] like Figure 1 , Figure 2 and Figure 6 As shown, a limiting block 25 is fixed to one side of the connecting cylinder 2, and a limiting plate 26, which is slidably connected to the limiting block 25, is fixed to the bottom of the tank body 1; a camera 9 is fixedly inserted through the top of the tank body 1. The limiting plate 26 is located between the two sets of blades 62 and will not affect the normal movement of the blades 62. When the connecting cylinder 2 moves up and down, the limiting block 25 moves with the connecting cylinder 2 and can slide on the limiting plate 26, increasing the stability of the connecting cylinder 2 when it moves; the camera 9 can display the position of the stirring blade 61 inside the tank body 1 on an external screen. The operator can view the position of the stirring blade 61 through the external screen so that the connecting cylinder 2 will not collide with the blade 62 when it moves upward.
[0024] In use, after the solution in tank 1 has been mixed, the solenoid valve 41 can be opened to allow the solution in tank 1 to enter the connecting pipe 4 through the sampling pipe 42. Then, the solenoid valve 41 is closed, and the solution can be discharged through the second folding pipe 43, completing the sampling of the solution near the bottom of tank 1. When it is necessary to sample the solution at different heights in tank 1, the electric telescopic rod 52 can be activated to drive the connecting cylinder 2 to move upward, so that the first folding pipe 21 is stretched, and the second folding pipe 43 is stretched accordingly. When the sampling pipe 42 is at the specified height, the solenoid valve 41 can be opened to complete the sampling of the solution at different heights in tank 1.
[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
