Description

Technical Field

[0001] The invention relates to the technical field of fluid performance measurement, and in particular to a high-temperature viscosity detection device. Background Art

[0002] In the production and preparation process of granular fluids such as protective slag, slag, hot melt adhesive, asphalt, etc., viscosity is an important physical property and technical indicator of granular fluids. Accurately measuring its viscosity is of great significance in many fields of industry and scientific research. Viscosity testing is the basis for ensuring fluidity, optimizing processes, ensuring safety and improving product quality. It has important guiding significance for industrial production and material research. Reasonable viscosity monitoring can effectively improve the controllability and reliability of the production process.

[0003] At present, when testing the viscosity of granular fluids, viscosity testing equipment is usually used for high-temperature testing. Especially for the viscosity testing of granular fluids, most of them use rotational viscometers for viscosity testing. However, the existing viscosity testers still have the following shortcomings in the process of viscosity testing:

[0004] 1. When testing the viscosity of a granular fluid, it is often necessary to heat the granular fluid at a high temperature. Although the furnace in the existing viscosity tester can heat the granular fluid, the heating devices are installed in a fixed position, so the furnace cannot be heated evenly during the heating process, which leads to the granular fluid in the furnace not being heated evenly. The unevenly heated granular fluid will seriously affect the accuracy of subsequent viscosity testing;

[0005] 2. Most existing viscosity testers use static heating to heat the particle fluid. In addition, the uniformity of heating cannot be guaranteed, which makes the particle fluid very easy to be stratified. The stratified particle fluid not only leads to uneven fluidity, but also uneven distribution, which affects its physical and chemical properties, and thus seriously affects the subsequent viscosity test results.

[0006] 3. During the viscosity test, the rotor for measuring viscosity is driven by a motor, which will produce slight vibrations. In addition, the load of the particle fluid on the rotor will cause the rotor of the viscosity tester to vibrate easily during rotation. The vibration of the rotor will affect the measurement accuracy, resulting in unstable or inaccurate viscosity readings.

[0007] 4. The rotors of existing viscosity testing equipment mostly adopt a columnar structure. When the columnar rotor rotates in the granular fluid for a certain period of time, the shear stress of the granular fluid on the rotor will gradually decrease, which seriously affects the accuracy of the viscosity measurement of the granular fluid.

[0008] Therefore, there is an urgent need for a high temperature viscosity detection device that can overcome the above-mentioned shortcomings. Summary of the invention

An electronic control display unit 32 for controlling the driving unit 33 and displaying viscosity information is provided on the upper part of the driving unit 33.

[0048] The measuring rod 34 is rotatably mounted with a bearing 35 coaxially arranged with the measuring rod 34. The upper part of the furnace cover 17 is provided with a stabilizing mechanism 2 which cooperates with the bearing 35 and is used to ensure the stable rotation of the measuring rod 34 and the corundum measuring rod 36. Specifically, the stabilizing mechanism 2 includes two furnace mouth refractory bricks 48 which can move synchronously in the same direction or in opposite directions. In order to realize the synchronous movement of the two furnace mouth refractory bricks 48 in the opposite direction or in opposite directions, side vertical plates 54 are provided on both sides of the upper surface of the furnace cover 17. The vertical plates 54 on both sides are respectively rotated. A bidirectional screw rod 53 penetrating two furnace mouth refractory bricks 48 and a guide rod 56 parallel to the bidirectional screw rod 53 and penetrating the two furnace mouth refractory bricks 48 are dynamically installed. The two furnace mouth refractory bricks 48 are respectively threaded with the two ends of the bidirectional screw rod 53. One end of the bidirectional screw rod 53 penetrates the side vertical plate 54, and a handle 55 is provided at its end. The bidirectional screw rod 53 is driven to rotate by rotating the handle 55, thereby driving the two furnace mouth refractory bricks 48 to move synchronously in the same direction or in reverse directions. The two furnace mouth refractory bricks The two refractory bricks 48 are provided with grooves A47 with open ends at both ends. As the two refractory bricks 48 move toward each other, when the two refractory bricks 48 are attached to each other, the grooves A47 on the opposite surfaces of the two refractory bricks 48 are spliced ​​to form a channel A52 coaxially arranged with the detection furnace mouth 18. The upper parts of the two refractory bricks 48 are provided with bearing blocks 43 that can move synchronously with the refractory bricks 48. The opposite surfaces of the two bearing blocks 43 are provided with grooves A47 from top to bottom. There are connected grooves C44 and grooves B46, the upper end of the groove C44 and the lower end of the groove B46 are both open structures, as the two bearing blocks 43 move toward each other, the grooves C44 and the grooves B46 on the opposite surfaces of the two bearing blocks 43 are spliced ​​from top to bottom to form a receiving cavity 49 coaxially arranged with the detection furnace mouth 18 and used to receive the bearing 35, and a channel B51 coaxially arranged with the detection furnace mouth 18, and the inner wall of the receiving cavity 49 is in interference fit with the outer ring surface of the bearing 35;

[0049] In the process of testing the viscosity of the high-temperature granular fluid, the two furnace mouth refractory bricks 48 and the two bearing blocks 43 are first driven to move synchronously in the opposite directions by the bidirectional screw 53, and then the measuring rod 34 and the corundum measuring rod 36 of the viscosity detection mechanism 1 are driven downward by the motor 9. When the corundum measuring rod 36 penetrates into the high-temperature granular fluid through the detection furnace mouth 18 and the bearing 35 on the measuring rod 34 corresponds to the groove C44 on the bearing block 43, the two furnace mouth refractory bricks 48 and the two bearing blocks 43 are driven to move synchronously in the opposite directions by the bidirectional screw 53. The carrier blocks 43 move toward each other synchronously. The accommodating cavity 49 formed by the moving and splicing of the carrier blocks 43 is used to accommodate the bearing 35. At the same time, its inner wall conflicts with the outer ring of the bearing 35. The diameters of the channels B51 and A52 are larger than the diameter of the corundum measuring rod 36. When the driving unit 33 drives the measuring rod 34 and the corundum measuring rod 36 to rotate, the inner ring of the bearing 35 rotates synchronously with the measuring rod 34, and the measuring rod 34 can also be horizontally limited, effectively avoiding the accuracy of the viscosity detection affected by the shaking of the measuring rod 34.

[0050] Several evenly distributed Forma wheels 16 are provided at the lower part of the base plate 13.

[0054] Example 4, please refer to the attached manual Figure 1 and 3 In the process of viscosity detection of the high-temperature granular fluid by the viscosity detection mechanism 1, since the corundum measuring rod 36 is usually a columnar structure, after the corundum measuring rod 36 rotates in the high-temperature granular fluid for a certain period of time, the rotation of the corundum measuring rod 36 will not be affected by the shear stress of the high-temperature granular fluid, resulting in inaccurate measurement results. In order to ensure that the corundum measuring rod 36 can effectively sense and measure the shear stress, the rod body of the corundum measuring rod 36 is provided with a plurality of protrusions 37 that are orderly arranged along the axial direction of the rod body of the corundum measuring rod 36 and arranged in an interlaced manner. The protrusions 37 can be an isosceles triangle structure in cross section, that is, the two end faces of the protrusions 37 are inclined faces, and the front ends of the two end faces intersect. Through the multiple protrusions 37 arranged in an interlaced manner, it can be ensured that the corundum measuring rod 36 can be effectively affected by the shear stress of the high-temperature granular fluid when rotating, providing strong support for the accurate detection of the viscosity of the high-temperature granular fluid.

[0055] Example 5, please refer to the attached manual Figure 5 and 6 In order to ensure that the viscosity detection mechanism 1 accurately measures the viscosity of the high-temperature particle fluid, the bearing 35 installed on the measuring rod 34 must ensure that it does not affect the rotation of the measuring rod 34. If the lower end face of the bearing 35 contacts the inner bottom surface of the accommodating chamber 49, the inner ring of the bearing 35 rotates with the measuring rod 34, and friction resistance may be generated between the inner ring end face of the bearing 35 and the inner bottom surface of the accommodating chamber 49. In order to avoid friction between the inner ring of the bearing 35 and the inner bottom surface of the accommodating chamber 49, a semi-ring support plate 45 is provided on the lower surface of the groove C44. As the two bearing blocks 43 move toward each other, the semi-ring support plates 45 in the two grooves C44 are spliced ​​to form a support ring 50 for supporting the outer ring end face of the bearing 35.

[0056] Example 6, please refer to the attached manual Figure 2 and8 After the viscosity test of the high-temperature particle fluid is completed, the high-temperature particle fluid needs to be cooled before cleaning. If it relies on natural cooling, it will take a lot of time. In order to speed up the cooling treatment of the high-temperature particle fluid, cooling pipes 20 arranged around the heat conduction cavity 22 are evenly distributed on the inner wall of the furnace outer cavity 19. After the cooling pipes 20 are connected to the cooling equipment to form a circulating cooling track, the cooling gas or coolant is injected into the cooling pipes 20 to quickly take away the heat, thereby realizing the rapid cooling treatment of the high-temperature particle fluid;

[0057] In order to improve the heating or cooling efficiency of the furnace body 11 on the high-temperature granular fluid, a sealing ring 57 is provided between the outer wall of the cavity opening of the heat conduction cavity 22 and the inner wall of the furnace outer cavity 19. The sealing ring 57 can be detachably installed by means of a threaded connection. The sealing of the sealing ring 57 can effectively prevent heat loss during the heating process of the high-temperature granular fluid, and can also speed up the subsequent cooling efficiency of the high-temperature granular fluid.

[0058] Embodiment 7, please refer to instructions 1 and 12. During the viscosity detection process of the high-temperature granular fluid by the viscosity detection mechanism 1, it is necessary to ensure the stability of the viscosity detection mechanism 1. Since the viscosity detection mechanism 1 is installed on the upper part of the mounting plate 5 which can be rotated and adjusted, if the mounting plate 5 is deflected due to vibration during the operation of the viscosity detection mechanism 1, it will affect the normal viscosity detection. For this reason, a limit plate 69 is provided on the side of the upper part of the movable part 6 away from the furnace body 11, which is perpendicular to the movable part 6 and corresponds to the mounting plate 5. A limit screw 70 is provided on the plate surface of the limit plate 69 away from the mounting plate 5, which passes through the limit plate 69 and is threadedly connected to the mounting plate 5. When the mounting plate 5 is rotated to make the viscosity detection mechanism 1 correspond to the furnace body 11, the end of the mounting plate 5 just corresponds to the limit plate 69. The limit plate 69 and the mounting plate 5 are connected by the limit screw 70, so that the mounting plate 5 can be fixed, thereby preventing it from deflecting and moving.
