Description

Technical Field

[0001] This utility model relates to the field of dynamic viscosity measurement technology, specifically a dynamic viscosity measuring instrument. Background Technology

[0002] Dynamic viscosity, also known as dynamic viscosity, absolute viscosity, or simple viscosity, is an instrument used to measure the viscosity of liquids. Liquid viscosity refers to the magnitude of the intermolecular forces within a liquid and is an important indicator of liquid flowability. Dynamic viscosity meters typically use rotational viscometers, which calculate the viscosity of a liquid by measuring the resistance it encounters during rotation.

[0003] For example, utility model CN221124206U discloses a dynamic viscosity meter. This utility model uses a first motor mounted on a lifting arm to rotate a viscometer, enabling viscosity testing of the liquid inside a measuring container. The lifting arm is installed inside a housing. A second motor inside the housing drives a lead screw and a threaded sleeve, allowing the lifting arm to detach the viscometer from the measuring container through a sliding groove and a slider. The measuring container is then separated from the meter by inserting a limiting handle into a fixed sleeve and pulling the measuring container upwards, thus facilitating cleaning. However, in actual use, after the measuring container is removed, some droplets adhere to the rotor and protective frame surfaces at the bottom of the meter, which were previously immersed in liquid. After removing the container, some of these droplets may drip onto the constant temperature heater, causing contamination. Subsequent cleaning and maintenance are required, making maintenance operations cumbersome.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a dynamic viscosity measuring instrument. Utility Model Content

[0005] The purpose of this invention is to provide a dynamic viscosity meter to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dynamic viscosity meter, comprising a base and a dehydration assembly. An electric push rod is disposed at the top center of the base, and the meter body is disposed at the top of the electric push rod. The dehydration assembly is disposed at one end of the top of the base. The dehydration assembly includes a fixed frame, a limiting rod, a support plate, a telescopic airbag, a first one-way valve, a second one-way valve, a connecting pipe, a diverter pipe, and a jet nozzle. The upper end of the fixed frame is slidably connected to the limiting rod, and the lower end of the limiting rod is fixed to the support plate. The top center of the support plate is disposed of the telescopic airbag, and the first one-way valve is fixed to one side of the upper part of the telescopic airbag. The second one-way valve is disposed on the other side of the upper part of the telescopic airbag, and the end of the second one-way valve is connected to the connecting pipe. The end of the connecting pipe is disposed of the diverter pipe, and the bottom of the diverter pipe is provided with a jet nozzle.

[0007] Furthermore, the fixing frame is n-shaped and is fixedly connected to the base.

[0008] Furthermore, there are two limiting rods symmetrically arranged about the center line of the fixed frame, and the limiting rods are fixedly connected to the main body of the measuring instrument.

[0009] Furthermore, the fixed frame is slidably connected to the support plate, and the fixed frame is also fixedly connected to the telescopic airbag.

[0010] Furthermore, the diverter is rectangular, and the bottom of the diverter is inclined.

[0011] Furthermore, an adjustment assembly is provided on one side of the electric push rod. The adjustment assembly includes a fixed plate, an anti-slip knob, and a screw. An anti-slip knob is rotatably connected to one end of the fixed plate, and a screw is connected to the bottom of the anti-slip knob.

[0012] Furthermore, the adjustment assembly also includes a lifting plate and a guide rod. The lifting plate is threadedly connected to the outer side of the middle part of the screw, and the guide rod is installed at the other end of the bottom of the fixed plate.

[0013] Furthermore, the lifting plate is fixedly connected to the diversion pipe, and the lifting plate is slidably connected to the guide rod.

[0014] This invention provides a dynamic viscosity meter, which has the following advantages:

[0015] 1. This utility model, through the setting of the liquid removal component, when the electric push rod drives the main body of the measuring instrument to move upward, causing the rotor and protective frame at the bottom of the measuring instrument to move out of the solution, the limiting rod will guide the fixed frame, thereby improving the stability of the measuring instrument during the upward movement process. At the same time, the limiting rod will also drive the tray to squeeze the telescopic airbag at the top of the fixed frame, thereby causing the airflow inside to be ejected from the jet nozzle at the bottom of the diverter pipe through the second one-way valve and the connecting pipe. The jet nozzle is tilted downward, so that during the upward movement of the rotor and the protective frame, the airflow can be used to intercept the liquid and accelerate the speed at which the liquid droplets on the surface fall off. Thus, when the rotor and the protective frame are removed from the container, large liquid droplets will not fall down and cause excessive pollution. Before using the equipment, when the electric push rod drives the main body of the measuring instrument to move downward, the tray will stretch the telescopic airbag, and the external air will be replenished into the telescopic airbag through the first one-way valve, so that it can be reused.

[0016] 2. By adjusting the configuration of the components, this utility model can use the lifting plate to cover the top of the container during the cleaning process to prevent some liquid from splashing out. At the same time, when using containers of different sizes, simply turn the anti-slip knob to rotate the screw. At this time, the guide rod will limit and guide the lifting plate, so the height of the lifting plate can be adjusted according to the needs, further expanding the adaptability of the equipment.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figures 1 to 3 As shown, a dynamic viscosity meter includes a base 1 and a dehydration assembly 4. An electric push rod 2 is mounted at the center of the top of the base 1, and the meter body 3 is mounted on the top of the electric push rod 2. The dehydration assembly 4 is located at one end of the top of the base 1 and includes a fixed frame 401, a limiting rod 402, a support plate 403, a telescopic airbag 404, a first one-way valve 405, a second one-way valve 406, a connecting pipe 407, a diverter pipe 408, and a jet nozzle 409. The limiting rod 402 is slidably connected inside the upper end of the fixed frame 401, and the lower end of the limiting rod 402... A support plate 403 is fixed at one end. The fixing frame 401 is n-shaped and fixedly connected to the base 1. Two limiting rods 402 are symmetrically arranged about the center line of the fixing frame 401 and are fixedly connected to the main body 3 of the measuring instrument. When the electric push rod 2 drives the main body 3 of the measuring instrument to move upward, the limiting rods 402 will guide the fixing frame 401 to improve the stability of the main body 3 during the upward movement. A telescopic airbag 404 is installed at the top center of the support plate 403 and is telescopic. A first one-way valve 405 is fixed to one side of the upper part of the airbag 404. The fixing frame 401 is slidably connected to the support plate 403, and the fixing frame 401 is also fixedly connected to the telescopic airbag 404. When the electric push rod 2 moves the measuring instrument body 3 downward, the support plate 403 will stretch the telescopic airbag 404, and the external air will be replenished into the telescopic airbag 404 through the first one-way valve 405. A second one-way valve 406 is installed on the other side of the upper part of the telescopic airbag 404, and the end of the second one-way valve 406 is connected to the connecting pipe 407. The end of the connecting pipe 407 is equipped with a diverter. The pipe 408 is rectangular and its bottom is inclined. When the baffle plate 403 moves upward, it will squeeze the telescopic airbag 404 on the upper part of the fixed frame 401, thereby causing the airflow inside to be ejected from the airbag 409 at the bottom of the pipe 408 through the second one-way valve 406 and the connecting pipe 407. The airbag 409 is inclined downward, so that the airflow can be used to intercept the liquid during the upward movement of the rotor and the protective frame, and accelerate the speed at which the liquid droplets fall off the surface.

[0023] like Figure 1As shown, an adjustment assembly 5 is provided on one side of the electric push rod 2. The adjustment assembly 5 includes a fixed plate 501, an anti-slip knob 502, and a screw 503. The anti-slip knob 502 is rotatably connected to one end of the fixed plate 501, and the screw 503 is connected to the bottom of the anti-slip knob 502. The anti-slip knob 502 can prevent the hand from slipping. The adjustment assembly 5 also includes a lifting plate 504 and a guide rod 505. The lifting plate 504 is threaded to the outer side of the middle part of the screw 503. The bottom of the fixed plate 501... The other end of the part is equipped with a guide rod 505. By simply turning the anti-slip knob 502, the screw 503 can be rotated. At this time, the guide rod 505 will limit and guide the lifting plate 504. Therefore, the height of the lifting plate 504 can be adjusted according to the needs, further expanding the adaptability of the equipment. The lifting plate 504 is fixedly connected to the diversion pipe 408, and the lifting plate 504 is slidably connected to the guide rod 505. During cleaning, the lifting plate 504 is used to cover the top of the container to prevent some liquid from splashing out.

[0024] In summary, when using this dynamic viscosity meter, firstly according to... Figure 1 , Figure 2 and Figure 3The structure shown involves first placing a container filled with the solution to be tested under the main body 3 of the measuring instrument. Then, rotating the anti-slip knob 502 causes the screw 503 to rotate. At this time, the guide rod 505 limits and guides the lifting plate 504, allowing the height of the lifting plate 504 to be adjusted as needed, thus shielding the top of the container. Next, the electric push rod 2 moves the main body 3 of the measuring instrument downwards, so that the rotor and protective frame at the bottom are located inside the container until the liquid level is aligned with the scale groove on the rotor. During this process, the support plate 403 extends the telescopic air bladder 404, and external air is supplied to the telescopic air bladder 404 through the first one-way valve 405. After waiting for a period of time until the temperature of the solution inside the container is the same as that of the rotor, the main body 3 of the measuring instrument (model DVNXLV) is started. It then drives the rotor to rotate through the internal motor, thereby calculating the viscosity of the liquid by measuring the resistance of the rotor during rotation. Then, after the test, the electric push rod 2 drives the measuring instrument body 3 to move upward, so that when the rotor and protective frame at the bottom of the measuring instrument body 3 are removed from the solution, the limiting rod 402 will guide the fixed frame 401, thereby improving the stability of the measuring instrument body 3 during the upward movement. At the same time, the limiting rod 402 will also drive the support plate 403 to squeeze the telescopic airbag 404 on the upper part of the fixed frame 401, so that the airflow inside it is ejected from the jet nozzle 409 at the bottom of the diversion pipe 408 through the second one-way valve 406 and the connecting pipe 407. The jet nozzle 409 is tilted downward, so that during the upward movement of the rotor and protective frame, the airflow can be used to intercept the liquid and accelerate the speed at which the liquid droplets fall off the surface. In addition, during the cleaning process, the lifting plate 504 can be used to cover the top of the container to prevent some liquid from splashing out. Finally, after the rotor and protective frame are removed from the container, the container is taken out and cleaned.

[0025] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
