Therefore, developing an instrument that can accurately measure the viscosity of granular fluids is of great significance for the research of the fluidity of granular fluids.

[0003] As an important parameter of fluid physical properties, the change in viscosity can reflect the change trend of fluid fluidity. There are various instrument devices for measuring viscosity, but most are used to measure the viscosity at normal temperature or the viscosity of high-temperature liquids. There are relatively few instrument devices for measuring the viscosity of granular fluids in a high-temperature soft molten state.

However, the viscosity of granular fluids in a high-temperature soft molten state is high and the fluidity is poor. During the rotation process of the cylindrical rotor, it is easy to have poor contact with the fluid, which affects the accuracy of the measurement data. Therefore, it is required that the rotor used in the viscometer device can be in good contact with the granular fluid completely.

[0032] Currently, the rotors of the main viscometers are mainly cylindrical, and can measure the viscosity of the melt well. However, the viscosity of the granular fluid in the high-temperature soft melting state is high and the fluidity is poor. During the rotation of the cylindrical rotor, poor contact with the fluid is likely to occur, thus affecting the accuracy of the measurement data. Therefore, it is required that the rotor used in the viscometer device can be in good contact with the granular fluid completely.

[0033] In view of this, we propose a rotor for testing the viscosity of a special binder for sintered permeable bricks.

[0034] Combined Figures 1 to 6 As shown, a rotor for testing the viscosity of a special binder for sintered permeable bricks, connected to a corundum rod, includes:

[0035] A linear rotor, including: a straight hook-shaped linear rotor 31, a cross-line hook-shaped linear rotor 32 or an S-curve-shaped linear rotor 33. The viscosity measurement ranges of the straight hook-shaped linear rotor 31, the cross-line hook-shaped linear rotor 32 and the S-curve-shaped linear rotor 33 for the special binder of permeable bricks increase in turn;

[0036] The straight hook-shaped linear rotor 31 includes: a straight rod 311 and two first arc-shaped rods 312.

The two second arc-shaped rods 331 are symmetrically arranged on the guide rod 2 with the guide rod 2 as the center. The two third arc-shaped rods 332 are respectively connected to the two ends of the two second arc-shaped rods 331 away from the guide rod 2. The bending directions of the two third arc-shaped rods 332 are opposite, and the arc radius of the two second arc-shaped rods 331 is smaller than the arc radius of the two third arc-shaped rods 332.

[0039] As an alternative embodiment, the straight hook-shaped linear rotor 31 is used for measuring the viscosity of a special binder for low-permeability bricks with a cohesive viscosity range between 1 cp and 5000 cp. The cross-line hook-shaped linear rotor 32 is used for measuring the viscosity of a special binder for medium-permeability bricks with a cohesive viscosity range between 5000 cp and 50000 cp. The S-curve linear rotor 33 is used for measuring the viscosity of a special binder for high-permeability bricks with a cohesive viscosity range between 50000 cp and 500000 cp.

[0040] As an alternative embodiment, a horizontal first pin hole 21 is provided below the side wall of the guide rod 2. The first pin hole 21 is used to connect the linear rotor 3. The bottom end of the guide rod 2 is conical; the height h of the conical part is 2.5 mm.

[0041] As an alternative embodiment, the first pin hole 21 on the guide rod 2 connected with the straight hook-shaped linear rotor 31 is linear, and the straight rod 311 is inserted into the first pin hole 21; the first pin hole 21 is 5 mm away from the tip of the conical bottom end of the guide rod 2, and the two first arc-shaped rods 312 are both tangent to the straight rod 311.

[0042] As an alternative embodiment, there are two first pin holes 21 on the guide rod 2 connected with the cross-line hook-shaped linear rotor 32. The two first pin holes 21 are both linear, and the two first pin holes 21 are vertically distributed in a cross shape on the guide rod 2. The two straight rods 311 respectively pass through the two first pin holes 21; specifically, the lower first pin hole 21 is 5 mm away from the tip of the conical bottom end of the guide rod 2, the upper first pin hole 21 is 10 mm away from the tip of the conical bottom end of the guide rod 2, and the distance between the two first pin holes 21 is 5 mm.

[0043] As an alternative embodiment, the first pin hole 21 on the guide rod 2 connected with the S-curve linear rotor 33 is curved, and the two second arc-shaped rods 331 are inserted into the first pin hole 21; the first pin hole 21 is 10.5 mm away from the tip of the conical bottom end of the guide rod 2.

[0044] As an alternative embodiment, a horizontal second pin hole 22 is provided above the side wall of the guide rod 2. A slot is provided at the bottom end of the corundum rod. The top end of the guide rod 2 extends into the slot. A connection hole corresponding to the second pin hole 22 is provided on the side wall of the slot. The guide rod 2 is connected to the corundum rod by a wire passing through the connection hole and the second pin hole 22. Specifically, the material of the wire can be stainless steel, molybdenum, high-temperature alloy steel, etc.

[0045] As an alternative embodiment, the diameter Φ of the guide rod 2 is 5 mm, and the total length of the guide rod 2 is 52.5 mm.

[0046] In the specific implementation of this linear rotor, the viscosity of the particulate fluid to be measured is predicted, and a rotor equipped with different linear rotors is selected. Then, the guide rod 2 is nested in the corundum rod 1, and the rotor is buried in the particulate fluid. Different rotation speeds are set on the rheometer, and the viscosity of the particulate fluid is measured as the rotating rod rotates, completing the viscosity test of the particulate fluid. Since the linear hook-shaped linear rotor 31, the cross-line hook-shaped linear rotor 32, or the S-curve-shaped linear rotor 33 gradually increases the contact area with the binder when measuring the viscosity of the special binder for permeable bricks with different viscosities during the test process.

[0047] In summary, the present invention provides a rotor for testing the viscosity of a special binder for sintered permeable bricks, which is mainly used for measuring the viscosity of the special binder for sintered permeable bricks, contributing to the optimization of the binder for sintered permeable bricks, energy conservation and consumption reduction in the sintering process, and the optimization of the performance of permeable bricks. However, the viscosities of other particulate fluids can also be measured with it, and the applicable range is extremely wide, and it can be used both at normal temperature and high temperature. Only different-shaped linear rotors need to be selected according to the different estimated viscosities of the particulate fluid. The popularization and application of this rotor have good social and economic benefits. Therefore, the present invention effectively overcomes the disadvantages in the prior art and has high utilization value.

[0048] The above embodiments are only specific implementation manners of the patent of the present invention, used to illustrate the technical solutions of the patent of the present invention, rather than limiting it. The protection scope of the patent of the present invention is not limited thereto.
