Description

Technical Field

[0001] This invention relates to the field of liquid viscosity analysis technology, and more particularly to a liquid medium viscosity analyzer. Background Technology

[0002] Liquid viscosity analysis refers to the process of studying the flow characteristics of liquids by measuring their viscosity. Viscosity is a physical quantity that measures the magnitude of internal friction in a liquid, typically describing the degree of "viscousness" during liquid flow. Understanding and controlling liquid viscosity is crucial in many industrial fields, such as fluid transport, chemical reactions, lubrication, and coating manufacturing. Liquid viscosity not only affects flowability but is also closely related to factors such as temperature, pressure, and the liquid's chemical composition.

[0003] Existing technology publication CN220708983U discloses a falling ball viscometer testing device. This device comprises a first test tube, an upper support, a lower support, a combined mounting bracket, a liquid infusion connector, and a second test tube. During operation, the device determines the test results based on the values ​​of a standard sample, the measured sample, and the error range, thereby obtaining more accurate test data. Furthermore, compared to previous methods relying on subjective human intervention, this device uses a microprocessor in an electronic circuit as the main controller, performing multiple tests and averaging the results, thus improving the accuracy of the device in testing liquid viscosity.

[0004] However, while this existing technology offers some improvement in the accuracy of test data, it still has shortcomings in the removal and cleaning of the spheres. Currently, the removal and cleaning of the spheres typically requires manual operation, which not only increases the complexity of the process but also increases the risk of human error. Especially when conducting multiple tests consecutively, manual operation lengthens the intervals between tests, thus reducing overall work efficiency.

Slider blocks are fixedly connected to both sides of the sliding ring. The sliders are slidably engaged with the inner wall of the cleaning seat. An inclined groove block is fixedly connected to the side of the sliding ring near the U-shaped rod. The inner wall of the inclined groove block is slidably engaged with the outer wall of the U-shaped rod.

[0014] Preferably, the ball cleaning mechanism includes a rotating seat, which is rotatably connected to a sliding ring. A transmission rod is slidably fitted on the inner wall of the bottom end of the rotating seat. The other end of the transmission rod is rotatably connected through the inner wall of the cleaning seat. A motor is fixedly connected to one end of the transmission rod located on the outside of the cleaning seat. The motor is fixedly connected to the cleaning seat.

[0018] 2. By incorporating a sphere cleaning mechanism within the cleaning chamber, utilizing a rotating cleaning dish and a reciprocating arc-shaped frame, comprehensive contact with the sphere surface is ensured during the cleaning process. This guarantees uniform cleaning of each sphere, avoiding omissions or uneven cleaning that may occur during manual cleaning. The cleaning method is more efficient, reducing the time and effort required for manual cleaning and improving work efficiency and consistency in viscosity analysis.

[0019] 3. By incorporating a sliding ring, when the ball falls into the cleaning dish, the sliding ring automatically closes the cover due to the ball's weight, eliminating the need for manual intervention. This reduces operational complexity and human error, enhances the automation level of the device, helps maintain the cleanliness of the cleaning space, and prevents the leakage or volatilization of harmful substances during the cleaning process.

[0029] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0030] like Figures 1-8 The liquid medium viscosity analyzer shown includes a device frame 1, a positioning frame 2 movably connected to the device frame 1, a liquid cylinder 3 fixedly connected to the positioning frame 2, a ball ejection mechanism 4 fixedly connected inside the liquid cylinder 3, a cleaning seat 5 fixedly connected to the device frame 1, a cover plate 6 rotatably connected to the cleaning seat 5, a sliding ring 7 slidably fitted inside the cleaning seat 5, and a ball cleaning mechanism 8 rotatably connected to the sliding ring 7.

[0031] like Figure 3As shown, a positioning seat 101 is fixedly connected to the bottom of the equipment frame 1. The positioning seat 101 has two symmetrically arranged positioning holes 105. An electric actuator A102 is fixedly connected to the inner wall of the upper end of the equipment frame 1. A ball seat 103 is fixedly connected to the output end of the electric actuator A102. The upper surface of the ball seat 103 has a conical surface and a through hole. A detection ball 104 is placed inside the ball seat 103. The detection ball 104 is placed on the ball seat 103, and then the electric actuator A102 moves the ball seat 103, causing the detection ball 104 on the ball seat 103 to fall from the equipment frame 1 into the liquid cylinder 3.

[0032] like Figure 4 As shown, the bottom end of the positioning frame 2 has two positioning rods 201 fixedly connected in a symmetrical structure, and the positioning rods 201 are movably inserted into the positioning holes 105. The positioning rods 201 at the bottom end of the positioning frame 2 are inserted into the positioning holes 105 on the positioning seat 101 for fixation.

[0033] like Figure 4 , Figure 5 As shown, the ball ejection mechanism 4 includes an electric actuator B401, which is fixedly connected to the inner wall of the bottom end of the liquid cylinder 3. A movable frame 402 is fixedly connected to the output end of the electric actuator B401. A ball pusher 403 is rotatably connected to the movable frame 402. The ball pusher 403 has a conical structure. A worm gear 404 is fixedly connected to one end of the ball pusher 403 that is connected to the movable frame 402.

[0034] A universal joint 405 is rotatably connected to the movable frame 402. A worm gear 406 is fixedly connected to one end of the universal joint 405, and the worm gear 406 meshes with a worm wheel 404 for transmission. An adjusting wheel 407 is fixedly connected to the other end of the universal joint 405. A fixed rack 301 is fixedly connected to the upper inner wall of the liquid cylinder 3, and the adjusting wheel 407 meshes with the fixed rack 301 for transmission. The electric actuator B401 drives the connected movable frame 402 to move upward, which in turn drives the ball pusher 403 to move upward, pushing the detection ball 104 out of the liquid cylinder 3. Then, when the adjusting wheel 407 meshes with the fixed rack 301, it drives the universal joint 405 connected to the adjusting wheel 407 to rotate, which in turn drives the worm gear 406 to rotate, which in turn drives the ball pusher 403 connected to the worm wheel 404 to rotate.

[0035] By incorporating a ball ejection mechanism 4 within the liquid cylinder 3, the detection ball 104 is automatically removed from the liquid after testing and falls into the cleaning seat 5. This eliminates the need for manual removal and placement of the detection ball 104 in the cleaning area, reducing operator workload, minimizing human error, and reducing direct contact between the operator and the liquid and detection ball 104. Especially when the liquid is hazardous or corrosive, this significantly reduces the risks and errors associated with manual operation, effectively improving the overall efficiency of viscosity analysis.

[0036] like Figure 6 As shown, a rotating shaft 601 is fixedly connected to one end of the cover plate 6. The rotating shaft 601 is rotatably connected to the cleaning seat 5. A transmission wheel 602 is fixedly connected to the bottom end of the rotating shaft 601. A transmission rack 603 is meshed on one side of the transmission wheel 602. A U-shaped rod 604 is fixedly connected to one end of the transmission rack 603. The U-shaped rod 604 is slidably fitted through the inner wall of the cleaning seat 5. The transmission rack 603 drives the rotating shaft 601 connected to the transmission wheel 602 to rotate, which in turn drives the connected cover plate 6 to rotate.

[0037] like Figure 7 As shown, the upper and lower inner walls of the sliding ring 7 are both annularly connected with multiple arc-shaped racks A701. Slider blocks 702 are fixedly connected to both sides of the sliding ring 7, and the sliders 702 are slidably engaged with the inner wall of the cleaning seat 5. A slanted groove block 703 is fixedly connected to the side of the sliding ring 7 closest to the U-shaped rod 604, and the inner wall of the slanted groove block 703 is slidably engaged with the outer wall of the U-shaped rod 604. The weight of the detection ball 104 causes the sliding ring 7 connected to the cleaning dish 805 to move downwards, which in turn causes the slanted groove block 703 to move downwards. At this time, the slanted groove block 703 causes the transmission rack 603 connected to the U-shaped rod 604 to move.

[0038] like Figure 8 As shown, the ball cleaning mechanism 8 includes a rotating seat 801, which is rotatably connected to the sliding ring 7. A transmission rod 802 is slidably fitted on the inner wall of the bottom end of the rotating seat 801. The other end of the transmission rod 802 is rotatably connected to the inner wall of the cleaning seat 5. A motor 803 is fixedly connected to one end of the transmission rod 802 located on the outside of the cleaning seat 5. The motor 803 is fixedly connected to the cleaning seat 5. A spring 804 is fixedly connected to the bottom end of the rotating seat 801. The other end of the spring 804 is fixedly connected to the transmission rod 802.

[0039] A cleaning dish 805 is fixedly connected to the rotating base 801. An arc-shaped frame 806 is slidably fitted on the inner wall of the cleaning dish 805. Brush bristles 807 are fixedly connected to both the arc-shaped frame 806 and the cleaning dish 805. An arc-shaped rack B808 is fixedly connected to the arc-shaped frame 806. A pin is rotatably connected to the rotating base 801. A drive wheel 809 is fixedly connected to one end of the pin. The drive wheel 809 meshes with the arc-shaped rack A701 for transmission. A driven wheel 810 is fixedly connected to the other end of the pin. The driven wheel 810 meshes with the arc-shaped rack B808 for transmission. The motor 803 drives the transmission rod 802 to rotate, which in turn drives the washing dish 805 connected to the rotating seat 801 to rotate. At this time, under the action of the arc-shaped rack A701 on the sliding ring 7, the driving wheel 809 meshing with it will rotate in both directions, thereby causing the driving wheel 809 to drive the connected driven wheel 810 to rotate, which in turn causes the driven wheel 810 to drive the arc-shaped frame 806 connected to the arc-shaped rack B808 to reciprocate.

[0040] Working principle: When viscosity analysis of a liquid medium is required, an appropriate amount of liquid medium is first loaded into the liquid cylinder 3. Then, the positioning rod 201 at the bottom of the positioning frame 2 is inserted into the positioning hole 105 on the positioning seat 101 for fixation. Next, the test ball 104 is placed on the ball seat 103. Then, the electric actuator A102 drives the ball seat 103 to move, causing the test ball 104 on the ball seat 103 to fall from the equipment frame 1 into the liquid cylinder 3. The time it takes for the ball to fall is then measured by a timer or sensor. Typically, the time required for the test ball 104 to fall from a fixed height to another specific position, such as the bottom or a specified height, is measured. Finally, the viscosity of the liquid is calculated by substituting the measured fall time, the density of the liquid, and the parameters of the test ball 104 into a calculation formula such as the Stokes formula.

[0041] Then, the electric actuator B401 drives the connected movable frame 402 to move upward, which in turn drives the ball pusher 403 to move upward, pushing the detection ball 104 out of the liquid cylinder 3. Then, when the adjusting wheel 407 meshes with the fixed rack 301, it drives the universal joint 405 connected to the adjusting wheel 407 to rotate, which in turn drives the worm gear 406 connected to rotate. This causes the worm gear 406 to drive the ball pusher 403 connected to the worm wheel 404 to rotate, so that the detection ball 104 on the ball pusher 403 can automatically roll into the cleaning dish 805.

[0042] At this time, the weight of the detection ball 104 will cause the sliding ring 7 connected to the cleaning dish 805 to move down, which will cause the sliding ring 7 to cause the connected inclined block 703 to move down. At this time, the inclined block 703 will cause the transmission rack 603 connected to the U-shaped rod 604 to move, which will cause the transmission rack 603 to drive the rotating shaft 601 connected to the transmission wheel 602 to rotate, which will cause the rotating shaft 601 to drive the connected cover plate 6 to rotate to the upper end of the cleaning seat 5 for sealing.

[0043] Then, the motor 803 drives the transmission rod 802 to rotate, which in turn drives the cleaning dish 805 connected to the rotating seat 801 to rotate. At this time, under the action of the arc-shaped rack A701 on the sliding ring 7, the driving wheel 809 meshing with it will rotate in both directions, thereby causing the driving wheel 809 to drive the driven wheel 810 connected to it to rotate. This causes the driven wheel 810 to drive the arc-shaped frame 806 connected to the arc-shaped rack B808 to move back and forth, and the brush bristles 807 clean the liquid medium on the outer wall of the detection ball 104.
