Abstract
Description
Technical Field
[0001] This utility model relates to the field of liquid detection technology, specifically to a magnetically levitated pipeline fluid viscosity detection device. Background Technology
[0002] Continuous automatic measurement and control of fluid viscosity is required in many industrial production processes. Viscosity is an important physical parameter for measuring a liquid's ability to resist flow. Viscosity measurement is closely related to fields such as petroleum, chemical, power, metallurgy, and national defense. It is an important means of industrial process control, improving product quality, and saving and developing energy.
[0003] The conventional viscosity testing procedure involves first taking samples on-site and then sending them to the laboratory for testing. However, the fluid on-site often flows inside pipelines, which can affect the normal transport of materials. In addition, there is time involved in sampling and testing, making the testing process cumbersome. Furthermore, the extracted raw materials cannot be reintroduced into the transport pipeline, resulting in a waste of test materials. Utility Model Content
[0004] The purpose of this invention is to provide a magnetically levitated pipeline fluid viscosity detection device to solve the above problems, as detailed below.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] This utility model provides a magnetic levitation pipeline fluid viscosity detection device, including a feed pipe and a rotational viscometer body. A receiving pipe is connected to the side wall of the feed pipe. A detection box is fixedly connected to the upper surface of the feed pipe. The lower side of the detection box is connected to the receiving pipe through an L-shaped tube. The detection end of the rotational viscometer body is located inside the detection box. A linkage rod that moves along the axis of the receiving pipe is provided at the axis of the receiving pipe. A plug is fixedly connected to one end of the linkage rod inside the receiving pipe, and the plug is adapted to the port of the receiving pipe. A piston for extracting or pushing liquid is sleeved on the outside of the linkage rod.
[0007] Preferably, the connection between the L-shaped tube and the material receiving tube is close to the material conveying tube, and a valve is fixedly installed on the vertical side wall of the L-shaped tube.
[0008] Preferably, the end of the material receiving tube is provided with a through hole and a vent hole, the middle of the piston is fixedly connected with a sleeve that passes through it, and the sleeve is slidably connected in the through hole, and the linkage rod is slidably connected in the sleeve.
[0009] Preferably, a sealing ring 1 is fixedly connected to the inner wall of the end of the sleeve, and the sealing ring 1 abuts against the surface of the linkage rod. Several sealing rings 2 are fixedly connected to the outer side of the piston, and the sealing rings 2 abut against the inner wall of the feed tube.
[0010] Preferably, a connecting plate is fixedly connected to one end of the linkage rod, and a threaded rod is rotatably connected to the other end of the connecting plate. A threaded sleeve that is threadedly connected to the threaded rod is fixedly connected to one end of the material taking tube.
[0011] Preferably, the end of the sleeve is fixedly connected to two levers, and the end face of the feed tube and the connecting plate are provided with bolts for fixing the position of the levers.
[0012] Preferably, the bolted connector includes a bolt rotatably connected to two dial plates, with the two bolts arranged in opposite directions.

[0016] The beneficial effects are:
[0017] Two levers drive the piston to move within the feed tube.

Detailed Implementation
[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0028] See Figures 1-6 As shown, this utility model provides a magnetic levitation pipeline fluid viscosity detection device, including a feed pipe 1 and a rotational viscometer body 3. A feed tube 2 is connected to the side wall of the feed pipe 1. A detection box 4 is fixedly connected to the upper surface of the feed pipe 1. The lower side of the detection box 4 is connected to the feed tube 2 through an L-shaped tube 10. The detection end of the rotational viscometer body 3 is located inside the detection box 4. A linkage rod 7 that moves along the axis of the feed tube 2 is provided at the axis of the feed tube 2. A plug 6 is fixedly connected to one end of the linkage rod 7 inside the feed tube 2. The plug 6 is adapted to the port of the feed tube 2. A piston 5 for extracting or pushing liquid is sleeved on the outside of the linkage rod 7.
[0029] As an optional implementation, the connection between the L-shaped tube 10 and the material taking tube 2 is close to the material conveying tube 1. A valve 11 is fixedly installed on the vertical side wall of the L-shaped tube 10, which allows the piston 5 to push more thoroughly into the detection box 4 when it is pushed inside the material taking tube 2. The valve 11 can control whether the L-shaped tube 10 is blocked, thereby controlling whether the liquid flows smoothly.
[0030] Reference Figure 2 As shown, a through hole 8 and a vent hole 9 are provided at the end of the material receiving tube 2. A sleeve 501 is fixedly connected to the middle of the piston 5, and the sleeve 501 is slidably connected in the through hole 8. The linkage rod 7 is slidably connected in the sleeve 501. The through hole 8 makes the movement of the sleeve 501 more stable, and the sleeve 501 makes the movement of the linkage rod 7 more stable. At the same time, the vent hole 9 can ensure the air pressure balance on both sides of the piston 5, so that the piston 5 can move stably.
[0031] Reference Figure 2-3 As shown, a sealing ring 14 is fixedly connected to the inner wall of the end of the sleeve 501. The sealing ring 14 abuts against the surface of the linkage rod 7. Several sealing rings 23 are fixedly connected to the outer side of the piston 5. The sealing rings 23 abut against the inner wall of the feed tube 2, which can effectively prevent the liquid drawn into the feed tube 2 from leaking from the piston 5 or the sleeve 501.
[0032] Reference Figure 2 As shown, a connecting plate 701 is fixedly connected to the end of the linkage rod 7, and a threaded rod 702 is rotatably connected to the other end of the connecting plate 701. A threaded sleeve 703, which is threadedly connected to the threaded rod 702, is fixedly connected to the end of the material taking tube 2. By rotating the threaded rod 702, it drives the plug 6 and piston 5 to move together through the threaded connection with the threaded sleeve 703, until the plug 6 completely seals the connection point of the material taking tube 2 (e.g., ...). Figure 5 As shown in the figure, it can control whether the plug 6 blocks the port connection of the feed tube 2.
[0033] Reference Figure 2 As shown in Figure 4, two lever plates 502 are fixedly connected to the end of the sleeve 501, and bolts for fixing the position of the lever plates 502 are provided on the end face of the material taking tube 2 and the connecting plate 701. The bolts include bolts 503 rotatably connected to the two lever plates 502, with one bolt 503 facing forward and the other backward. A nut 504 threadedly connected to one of the bolts 503 is fixedly connected to the end face of the material taking tube 2. A bolt hole 505 threadedly connected to the other bolt 503 is provided on the connecting plate 701. During testing, one bolt 503 is rotated to release its connection with the nut 504 (i.e., to release the locking state of the sleeve 501 and the piston 5). The two lever plates 502 drive the piston 5 to move in the material taking tube 2 until the other bolt 503 is connected to the bolt hole 505 on the connecting plate 701 (e.g., ...). Figure 4As shown in the figure, at this time, the piston 5 is locked with the connecting plate 701, and the control plate 502 can be connected and locked with the material taking tube 2 or the connecting plate 701, thereby freely controlling the piston 5 to pump or push liquid.
[0034] Furthermore, a sealing ring 3 12 is fixedly connected to the inner wall of the end of the material receiving pipe 2 that connects to the material conveying pipe 1, and the sealing ring 3 12 is in contact with and adapted to the plug 6. When the plug 6 moves to such a position... Figure 5 After the indicated position, the plug 6 is in close contact with the sealing ring 12, which prevents the liquid flowing in the conveying pipe 1 from entering the taking pipe 2, and also prevents the liquid inside the taking pipe 2 from leaking out from this point when it is pushed.
[0035] Specifically, the rotational viscometer body 3 is fixedly mounted on the upper side of the feed pipe 1 by a mounting bracket, which makes the detection process of the rotational viscometer body 3 more stable. The measurement process of the rotational viscometer body 3 is as follows: the stepper motor drives the A pointer, the hairspring (elastic element), the B pointer, the rotating shaft and the rotor to rotate at a constant speed. When the liquid is not sheared, no viscous torque is generated, and the A pointer and the B pointer coincide. If the rotor is placed in the liquid, the liquid is sheared and generates a viscous torque, which acts on the rotor, causing the hairspring to twist and generate torque. When this torque is balanced with the viscous torque, the instrument measures the angle between the two pointers A and B, i.e. the deflection angle of the hairspring, through the photoelectric unit, and provides the measurement data to the microcomputer processor for processing. Then, the viscosity value of the measured liquid is directly displayed on the display screen, in mPa·s.
[0036] Specifically, the test box 4 is made of transparent glass, which makes it easy to observe the color and height of the liquid inside the test box 4.
[0037] The working principle of this utility model:
[0038] During testing, rotate one side bolt 503 to disconnect it from the nut 504 (i.e., release the locking state of the sleeve 501 and piston 5). This allows the piston 5 to move within the feed tube 2 via the two levers 502, until the other bolt 503 connects to the bolt hole 505 on the connecting plate 701 (e.g., ...). Figure 4 As shown), at this time, piston 5 is locked to connecting plate 701. Then, rotate threaded rod 702 so that it moves plug 6 and piston 5 together through threaded connection with threaded sleeve 703, until plug 6 completely seals the port connection of feed tube 2 (as shown). Figure 5As shown), at this time, a portion of the flowing liquid enters the inside of the feeding tube 2. Then, the connection between the piston 5 and the connecting plate 701 is canceled and the valve 11 is opened. The liquid is then transported to the detection box 4 through the L-shaped tube 10 by pushing the piston 5 (at this time, the valve 11 is closed). Then, the rotational viscometer body 3 is started so that its detection end can detect the viscosity of the liquid in the detection box 4. After the detection is completed, the valve 11 is opened and the piston 5 is pulled back, which can draw the liquid in the detection box 4 back into the feeding tube 2. Then, the above steps are reversed to transport the detected liquid back into the feeding tube 1.
[0039] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
