Description

Technical Field

[0001] This utility model relates to the field of six-speed viscometer technology, specifically to a pressure-resistant, temperature-controlled, sealed six-speed viscometer capable of measuring the high-temperature viscosity of viscoelastic water-based solutions. Background Technology

[0002] A six-speed viscometer is an instrument used to measure the rheological parameters of viscoelastic water-based solutions such as drilling fluids. By detecting the viscosity of viscoelastic water-based solutions, the physical characteristics of fluid transport in the chemical industry can be analyzed. To improve the accuracy of viscosity detection, the viscoelastic water-based solution is usually heated during the test to simulate a high-temperature environment and then the viscosity of the viscoelastic water-based solution is measured.

[0003] Chinese utility model patent CN220983014U discloses a viscosity testing device, including "a base with an installation port; a vertical plate fixedly installed on the top of the base; a heat-conducting plate fixedly installed on the inner wall of the installation port; a measuring cup disposed on the top of the heat-conducting plate for detecting liquid viscosity; a digital viscometer disposed above the measuring cup for detecting liquid viscosity; several clamping heating mechanisms mounted on the base for heating the liquid; a cooling mechanism mounted on the base for cooling the liquid; and a lifting mechanism mounted on the vertical plate for adjusting the digital viscometer." However, when heating a viscoelastic water-based solution sample, the viscoelastic water-based solution sample inside the measuring cup is not in a sealed environment, and the mouth of the measuring cup is mostly exposed to the outside, causing internal heat loss. Directly using a six-speed viscometer for viscosity testing often results in errors in the test data, thus affecting the performance of the six-speed viscometer. Utility Model Content

[0004] The purpose of this invention is to provide a pressure-resistant, temperature-controlled, sealed six-speed viscometer capable of measuring the high-temperature viscosity of viscoelastic water-based solutions. This addresses the problem mentioned in the background art that the measuring cups for viscoelastic water-based solutions are mostly not in a sealed environment, which leads to errors in the test data when directly performing viscosity testing in a high-temperature environment, thus affecting the use of the six-speed viscometer.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressure-resistant, temperature-controlled, sealed six-speed viscometer capable of measuring the high-temperature viscosity of viscoelastic water-based solutions, comprising a base, a clamping assembly installed inside the base, a heating seat installed at the top center of the base, a measuring cup disposed inside the heating seat, a support frame fixedly connected to one side of the top of the base, a hydraulic cylinder installed at the top of the support frame, and a sealing cover installed at the bottom of the hydraulic cylinder.

[0006] The clamping assembly includes a clamping motor, one end of which is driven by a drive shaft, and both ends of the drive shaft are threadedly connected to limit rods. A clamping plate is installed at the top end of the limit rods.

[0007] The beneficial effects of this invention are as follows: by setting a lifting and lowering sealing cover and sealing cover above the measuring cup in the six-speed viscometer, the environment around the measuring cup and heating seat is sealed when the viscosity of viscoelastic water-based solutions is tested in a high-temperature environment, so as to avoid the loss of internal heat, ensure the accuracy of the six-speed viscometer when conducting high-temperature viscosity tests, and thus improve the performance of the six-speed viscometer.

[0008] To achieve clamping and fixing of the measuring cup:

[0009] Further configuration: the limiting rod is an inverted L-shaped structure, and both ends of the drive shaft are provided with external thread structures; the base has two internal limiting grooves, and the limiting rod is connected to both ends of the drive shaft and the limiting grooves through thread to form a sliding connection structure; the clamping plate is an arc-shaped structure, and the inner wall of the clamping plate and both sides of the measuring cup form a close-fitting connection structure; and the inner wall of the clamping plate is provided with an anti-slip layer.

[0010] By adopting the above technical solution, the measuring cup is clamped and fixed by setting two limit rods driven by the motor to move the clamping plates closer to each other, thus preventing the measuring cup from shaking during viscosity testing and improving the detection accuracy of the internal six-speed viscometer.

[0011] To enable the hydraulic components to open the sealing cover and sealing shield:

[0012] The hydraulic cylinder is further configured such that: a piston rod is driven to the bottom of the hydraulic cylinder; an abutment block is installed at the bottom of the piston rod; a sealing cover is installed at the bottom center of the abutment block; a viscometer body is installed at the bottom center of the sealing cover; the piston rod and the top center of the sealing cover form a through connection structure; and the top of the abutment block and the top inner wall of the sealing cover form a fitted connection structure.

[0013] By adopting the above technical solution, an abutment block is set on the piston rod, so that the piston rod drives the sealing cover to rise while the abutment block abuts the sealing cover and rises synchronously. This facilitates the synchronous opening of the sealing cover and the sealing cover, thereby facilitating the rapid feeding and discharging of the viscoelastic water-based solution in the measuring cup and improving the feeding and discharging rate of the six-speed viscometer.

[0014] To enable observation of the testing process of the six-speed viscometer:

[0015] The sealing cover is further configured as follows: the sealing cover is a square frame structure with the opening facing downwards, and both the sealing cover and the sealing cap are made of transparent, high-temperature resistant quartz glass.

[0016] By adopting the above technical solution, a transparent quartz glass sealing cap and cover are used to create a sealed environment for the heating zone of the measuring cup, reducing the rate of heat loss and thus improving the accuracy of the six-speed viscometer. At the same time, the transparent sealing cap and cover also make it easy for the operator to observe the internal testing process, ensuring the normal operation of the test.

[0017] To achieve the sealing of the piston rod by the sealing cap and sealing cover:

[0018] The configuration is further defined as follows: when the piston rod is at its maximum extension distance, the sealing cap is in contact with the top of the measuring cup, and the bottom of the sealing cover is in contact with the top of the base.

[0019] By adopting the above technical solution, the piston rod drives the sealing cover to descend and fit against the mouth of the measuring cup, and the abutment block simultaneously drives the sealing cover to fit and seal against the base, so that a closed environment is formed inside both the measuring cup and the sealing cover, thereby reducing the rate of internal heat loss and avoiding excessive heat loss from affecting the viscosity detection data of viscoelastic water-based solutions under high temperature conditions.

[0020] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0027] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0028] Please see Figures 1 to 5 A pressure-resistant, temperature-controlled, sealed six-speed viscometer for measuring the high-temperature viscosity of viscoelastic water-based solutions includes a base 1, a clamping assembly 2 installed inside the base 1, a heating seat 3 installed at the top center of the base 1, a measuring cup 4 installed inside the heating seat 3, a support frame 5 fixedly connected to one side of the top of the base 1, a hydraulic cylinder 6 installed at the top of the support frame 5, and a sealing cover 7 installed at the bottom of the hydraulic cylinder 6.

[0029] The clamping assembly 2 includes a clamping motor 201, one end of which is driven by a drive shaft 202. Both ends of the drive shaft 202 are threadedly connected to limit rods 203, and a clamping plate 204 is installed on the top end of the limit rods 203.

[0030] In this embodiment, as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the limiting rod 203 has an inverted L-shaped structure, and both ends of the drive shaft 202 are provided with external thread structures. The base 1 has two internally embedded limiting grooves 101, and the limiting rod 203 is connected to both ends of the drive shaft 202 and the limiting grooves 101 through thread to form a sliding connection structure. The clamping plate 204 has an arc-shaped structure, and the inner wall of the clamping plate 204 and the two sides of the measuring cup 4 form a close-fitting connection structure. The inner wall of the clamping plate 204 is provided with an anti-slip layer.

[0031] In this embodiment, as Figure 1 and Figure 3 As shown, a piston rod 601 is driven and connected to the bottom of the hydraulic cylinder 6. An abutment block 602 is installed at the bottom of the piston rod 601. A sealing cover 603 is installed at the bottom center of the abutment block 602. A viscometer body 604 is installed at the bottom center of the sealing cover 603. The piston rod 601 and the top center of the sealing cover 7 form a through connection structure, and the top of the abutment block 602 and the top inner wall of the sealing cover 7 form a close-fitting connection structure.

[0032] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the sealing cover 7 is a square frame structure with the opening facing downwards, and both the sealing cover 603 and the sealing cover 7 are made of transparent, high-temperature resistant quartz glass.

[0033] In this embodiment, as Figure 2 and Figure 3As shown, when the piston rod 601 is at its maximum extension distance, the sealing cover 603 is in contact with the top of the measuring cup 4, and the bottom of the sealing cover 7 is in contact with the top of the base 1.

[0034] The computer software involved in the hardware carriers such as the clamping motor, heating seat, hydraulic cylinder, and viscometer body in the technical solution is software technology known to those skilled in the art. It is merely applied to the aforementioned hardware carriers. In other words, the computer software portion of the technical solution is an essential technical feature for solving the aforementioned technical problem, constituting a necessary technical feature for the technical problem solved by this application, but it is not a differentiating technical feature or a point of technical improvement. The applicant has not made any technical improvements to the computer software portion involved in the aforementioned hardware carriers, nor is it a key technical point of the invention.

[0035] Therefore, the "clamping motor", "heating seat", "hydraulic cylinder", "viscometer body" and other components involved in this application are physical functional modules that combine existing computer software programs or protocols with the hardware carrier of this application. The computer software programs involved in these physical functional modules are all technologies known to those skilled in the art and are not improvements of this application. The improvement of this application should be the interaction between the various physical functional modules, that is, the improvement of the overall structure of the six-speed viscometer of this application, in order to solve the corresponding technical problems to be solved by this application.

[0036] This pressure-resistant, temperature-controlled, sealed six-speed viscometer, capable of measuring the high-temperature viscosity of viscoelastic water-based solutions, operates as follows:

[0037] First, the operator places the measuring cup 4 containing the viscoelastic water-based solution on the heating seat 3 on the base 1, and heats the viscoelastic water-based solution in the measuring cup 4 through the heat-conducting plate and ceramic base inside the heating seat 3.

[0038] Then, the clamping motor 201 (model: MS1-R) is started to drive the drive shaft 202 to rotate in the base 1, which in turn drives the limit rods 203 connected by threads at both ends to slide towards each other in the limit groove 101 of the base 1, which in turn drives the arc-shaped clamping plates 204 at the top to move closer to each other, thereby clamping and fixing the measuring cup 4 in the center.

[0039] After the measuring cup 4 is clamped, hydraulic oil is injected into the hydraulic cylinder 6 (model: HSG63) at the top of the support frame 5 by starting the external hydraulic oil pump. This causes the piston rod 601 to extend and move up and down, thereby driving the sealing cover 603 connected to the bottom of the piston rod 601 to move up and down. At the same time, the abutment block 602 at the top of the sealing cover 603 drives the sealing cover 7 at the top to move up and down synchronously. When the sealing cover 603 descends to fit against the top of the measuring cup 4, the viscometer body 604 (model: ZNN-D6B) is inside the measuring cup 4, and the abutment block 602 is separated from the top inner wall of the sealing cover 7. The bottom of the sealing cover 7 is in contact with the top of the base 1. After the temperature inside the measuring cup 4 rises to a suitable temperature, the viscosity of the viscoelastic water-based solution in a high-temperature environment can be detected by the viscometer body 604.

[0040] Finally, after the test is completed, the sealing cap 603 and sealing cover 7 are reset, and the measuring cup 4 held by the clamping plate 204 is opened. The measuring cup 4 can then be taken out for further processing of the viscoelastic water-based solution inside.
