Description

Technical Field

[0001] This application relates to the field of solution testing equipment, and in particular to a fully automatic polyacrylamide screen coefficient measuring device. Background Technology

[0002] The screen factor is the ratio of the time it takes for a polyacrylamide solution to flow through a viscometer with a specific screen to the time it takes for a standard brine solution to flow through the same viscometer. The screen factor is an important parameter for measuring the rheological properties of a solution and has important applications in the chemical industry.

[0003] The existing sieve coefficient is determined by a viscometer, which includes a spherical liquid-containing chamber I, a spherical liquid-containing chamber II, and a glass tube. The glass tube connects the spherical liquid-containing chamber I and the spherical liquid-containing chamber II. The spherical liquid-containing chamber I and the spherical liquid-containing chamber II are respectively connected to an inlet pipe and an outlet pipe. The inlet pipe, the outlet pipe, and the glass tube are arranged coaxially. When the viscometer is set vertically, the solution is poured into the inlet pipe, allowing the solution to flow vertically within the viscometer. By setting graduations on the glass tube, it is convenient for users to record the solution flow time.

[0004] The aforementioned technical solutions have the following drawbacks: the viscometer needs to be moved vertically during the measurement process, and after moving the viscometer vertically, it needs to be readjusted to a vertical position, which takes a long time. Utility Model Content

[0005] To improve measurement efficiency, this application provides a fully automatic polyacrylamide screen coefficient measuring device.

[0006] The fully automatic polyacrylamide screen coefficient measuring device provided in this application adopts the following technical solution: An automatic polyacrylamide screen coefficient measuring device includes a viscometer and a bracket. The viscometer includes a spherical liquid-containing chamber I, a spherical liquid-containing chamber II, and a glass tube. The glass tube passes through the spherical liquid-containing chamber I and the spherical liquid-containing chamber II. The glass tube has an upper scale line and a lower scale line. The bracket includes a guide rod, a base frame, and multiple support plates. One end of the guide rod is fixed to the base frame. The guide rod is perpendicular to the base frame. The support plates are slidably connected to the guide rod. The multiple support plates are respectively engaged with the spherical liquid-containing chamber I and the spherical liquid-containing chamber II.

[0007] By adopting the above technical solution, and by setting a guide rod on the base frame, the guide rod can remain vertical when the base frame is set on the table. By setting the tray on the guide rod, the tray can slide vertically on the guide rod. When the viscometer is mounted on the tray, the viscometer slides vertically on the guide rod via the tray. During the movement of the viscometer, the viscometer always remains vertical. There is no need to continue to adjust the position of the viscometer during the experiment, which can improve the measurement efficiency.

[0008] Optionally, the base frame is provided with multiple adjusting bolts, which pass through the base frame and are threadedly connected to it.

[0009] By adopting the above technical solution, multiple adjusting bolts are set on the base frame. The adjusting bolts pass through the base frame and are threadedly connected to the base frame. When the adjusting bolts are turned, the adjusting bolts can move vertically relative to the base frame. By adjusting the multiple adjusting bolts, the user can adjust the base frame to make the base frame horizontal, thereby keeping the guide rod vertical. When the viscometer is installed on the support plate, the viscometer can be kept vertical, and the direction of the viscometer sliding through the support plate is vertical.

[0010] Optionally, a bubble level is provided on the base frame.

[0011] By adopting the above technical solution, and by installing a bubble level on the base frame, the bubble level can indicate the tilt direction of the base frame. Users can adjust the adjusting bolts at different positions according to the position of the bubble on the bubble level, which is convenient for use.

[0012] Optionally, the tray includes a horizontal plate and multiple arc-shaped plates. The horizontal plate is slidably connected to the guide rod, and the multiple arc-shaped plates are fixed on the horizontal plate. The arc-shaped plates are used to engage with the outer wall of the first or second spherical liquid-containing cavity.

[0013] By adopting the above technical solution, by setting an arc-shaped plate on the horizontal plate, the arc-shaped plate can fit against the bottom of the spherical liquid-containing cavity, thereby supporting the spherical liquid-containing cavity and keeping the viscometer fixed on the support plate.

[0014] Optionally, gaps are provided between the arc-shaped plates to form a slot, and the glass tube is placed in the slot.

[0015] By adopting the above technical solution, a slot is opened between the curved plates, allowing the glass tube to be placed in the slot and move horizontally. This enables the viscometer to be detachably connected to the tray, making it convenient for users to install viscometers of different sizes on the tray.

[0016] Optionally, the pallet is provided with a connecting rod, one end of which is connected to a horizontal plate.

[0017] By adopting the above technical solution, a connecting rod is set on the tray to connect the two trays. When the user slides the tray, the two trays slide simultaneously and drive the two spherical liquid-containing chambers to move, thereby achieving the effect of adjusting the height of the viscometer.

[0018] Optionally, the guide rod is provided with multiple magnets for magnetic connection with the tray.

[0019] By adopting the above technical solution, two magnets are set on the guide rod, allowing the tray to slide between the two magnets. The tray can abut against the two magnets respectively, thereby keeping the tray fixed at different heights on the bracket.

[0020] Optionally, a plumb line is provided on the pallet, with one end of the plumb line fixed to the pallet and the other end fixedly connected to a counterweight.

[0021] By adopting the above technical solution, a plumb line is set on the pallet, and a counterweight is set on the plumb line, so that the plumb line can remain vertical under the action of the counterweight. The user can use the plumb line to check the position of the base frame and adjust the adjusting bolts.

[0022] In summary, the beneficial technical effects of this application are as follows: 1. By setting a guide rod on the base frame, the guide rod can remain vertical when the base frame is set on the table. By setting the tray on the guide rod, the tray can slide vertically on the guide rod. When the viscometer is mounted on the tray, the viscometer slides vertically on the guide rod via the tray. During the movement of the viscometer, the viscometer always remains vertical. There is no need to continue to adjust the position of the viscometer during the experiment, which can improve the measurement efficiency. 2. Multiple adjusting bolts are installed on the base frame. The adjusting bolts pass through the base frame and are threadedly connected to the base frame. When the adjusting bolts are turned, the adjusting bolts can move vertically relative to the base frame. By adjusting the multiple adjusting bolts, the user can adjust the base frame to make the base frame horizontal, thereby keeping the guide rod vertical. When the viscometer is installed on the support plate, the viscometer can be kept vertical. When the viscometer slides through the support plate, the direction is vertical. 3. By installing a bubble level on the base frame, the bubble level can indicate the tilt direction of the base frame. Users can adjust the adjusting bolts at different positions according to the position of the bubble on the bubble level, which is convenient for use. Attached Figure Description

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] This application discloses a fully automatic polyacrylamide screen coefficient measuring device, referring to... Figure 1 and Figure 2 The viscometer includes a viscometer 1 and a bracket 2. The bracket 2 is used to set the viscometer on a table, and the viscometer 1 is detachably connected to the bracket 2. The viscometer 1 includes a first spherical liquid-containing chamber 11, a second spherical liquid-containing chamber 12, and a glass tube 13. The glass tube 13 passes through and connects the first spherical liquid-containing chamber 11 and the second spherical liquid-containing chamber 12. The diameter of the first spherical liquid-containing chamber 11 is smaller than the diameter of the second spherical liquid-containing chamber 12. The glass tube 13 is provided with an upper graduation line 131 and a lower graduation line 132. The upper graduation line 131 is located between the first spherical liquid-containing chamber 11 and the second spherical liquid-containing chamber 12, and the lower graduation line 132 is located below the second spherical liquid-containing chamber 12. When measuring the sieve coefficient, the viscometer 1 is vertically set on the bracket 2. At this time, the glass tube 13 is vertically set, and the second spherical liquid-containing chamber 12 is located below the first spherical liquid-containing chamber 11. When determining the sieve coefficient, the sample solution needs to be poured into a beaker. The lower end of the glass tube 13 of the viscometer 1 is placed inside the beaker, slightly above the bottom of the beaker. The sample solution is then drawn into the upper end of the glass tube 13 of the viscometer 1. While maintaining a stable liquid level, the lower end of the viscometer 1 is raised above the surface of the sample solution in the beaker. The sample solution is then diluted, and the flow time of the sample solution falling into the spherical liquid-holding chamber 12 of the viscometer 1 is recorded using a stopwatch. Finally, the sieve coefficient of the solution is calculated.

[0028] Reference Figure 1 A valve 133 is provided on the glass tube 13. The valve 133 is located at the end of the glass tube 13 near the spherical liquid-holding chamber 12. The valve 133 is used to control the opening and closing of the glass tube 13. The user can use the valve 133 to make the liquid flow vertically in the viscometer 1 and fall into the beaker.

[0029] Reference Figure 1 The bracket 2 includes a guide rod 21, a base frame 22, and multiple trays 23. One end of the guide rod 21 is fixed to the base frame 22, which is used to place the bracket on a table. The multiple trays 23 are slidably connected to the guide rod 21. Multiple adjusting bolts 221 are provided on the base frame 22. The adjusting bolts 221 vertically penetrate the base frame 22 and are threadedly connected to it. The lower end of the adjusting bolts 221 abuts against the ground. By turning the adjusting bolts 221, the user can adjust the base frame 22 to a horizontal position, thereby ensuring the guide rod 21 is vertical. When the viscometer 1 is placed on the bracket 2, the glass tube 13 remains vertical, improving the detection accuracy.

[0030] Reference Figure 1A bubble level 222 is installed on the base frame 22, and the bubble level 222 is installed on the upper surface of the base frame 22. When the user turns the adjusting bolt 221, the bubble level 222 can be observed, which makes it convenient for the user to adjust the bracket 2.

[0031] Reference Figure 2 The support plate 23 includes a horizontal plate 231 and multiple arc-shaped plates 232. A guide rod 21 passes through the horizontal plate 231, and the horizontal plate 231 is slidably connected to the guide rod 21. The arc-shaped plates 232 are disposed on the horizontal plate 231, and the arc-shaped plates 232 fit against both sides of the spherical liquid-containing cavity, thereby locking the spherical liquid-containing cavity. There is a gap between two arc-shaped plates 232 on the same side, forming a groove 233, in which the glass tube 13 is disposed. By setting two support plates 23 on the guide rod 21, the two support plates 23 respectively support the first spherical liquid-containing cavity 11 and the second spherical liquid-containing cavity 12, thereby enabling the viscometer 1 to be vertically suspended.

[0032] Reference Figure 1 Two vertically oriented connecting rods 24 are mounted on the two support plates 23. One end of each connecting rod 24 is connected to a horizontal plate 231. The user can slide the support plates 23 vertically via the connecting rods 24, thus achieving the effect of vertically moving the viscometer 1. Two magnets 25 are fixed to the guide rod 21, which abut against and magnetically connect to the horizontal plate 231. The upper support plate 23 abuts against one magnet 25, and the lower support plate 23 abuts against the other magnet 25. By sliding the support plates 23 vertically between the two magnets 25, the viscometer 1 can slide vertically. During the sliding process, the base frame 22 remains horizontal, thus ensuring that the viscometer 1 slides vertically, resulting in high accuracy of the measurement data.

[0033] Reference Figure 1 A plumb line 26 is provided on the support plate 23. One end of the plumb line 26 is fixed on the support plate 23, and the other end is fixedly connected to a counterweight 27. The plumb line 26 is used to show the direction of the gravity line, so that the user can easily check the position of the viscometer 1 and adjust the adjusting bolt 221.

[0034] The implementation principle of this application embodiment is as follows: by setting a support plate 23 on the guide rod 21, the spherical liquid-containing cavity 11 and the spherical liquid-containing cavity 12 can be respectively engaged on the support plate 23, thereby enabling the viscometer 1 to remain vertical on the bracket 2, improving the accuracy of the measurement data. By setting two magnets 25 on the guide rod 21, the two support plates 23 can be respectively attracted to the magnets 25 when sliding, thereby enabling the viscometer 1 to move vertically and be fixed at different heights, facilitating experiments and improving measurement accuracy.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
