A rotor for a dispersibility tester

Abstract

The invention discloses a rotor for a dispersibility tester. The rotor consists of a disc 1, a truncated cone 2, a triangular prism 3 and a blade 4. A truncated cone with a groove is fixed at the center of the upper surface of the disc, 6 triangular prisms are evenly inlaid on the upper surface of the disc, and 8 blades are evenly inlaid on the circumferential surface of the disc. The rotor rotates, driving the water flow to rotate to form a vortex, which has a dispersing effect on the sample paper in the water. The rotor can generate a larger vortex, increase the shear force of the water, and at the same time make the water flow have an upward trend, which can increase the dispersion of the sample paper and make the sample paper less likely to sink.

Description

Technical Field

[0001] The present invention relates to a rotor for a dispersibility tester. Technical Background

[0002] There are many types of toilet paper in China, and there is no uniform standard for dispersibility. The dispersibility of toilet paper directly affects the decomposition time in flush toilets and sewer pipes. Toilet paper with good dispersibility will decompose quickly in sewers or septic tanks and smoothly enter sewage treatment facilities. If toilet paper cannot decompose quickly and is discharged into the sewer, many adverse consequences will occur.

[0003] The dispersibility tester is used to test the dispersibility of toilet paper by disintegrating it in a stable vortex by the shear force of water. During the process of testing the dispersibility of toilet paper by the dispersibility tester, the toilet paper will sink to the bottom of the liquid with the vortex in the liquid and be broken by the rotating rotor, causing the test to fail. Summary of the invention

[0004] 1. Aiming at the disadvantage of the existing dispersibility tester that toilet paper sinks in the vortex and is broken by mechanical force, the technical problem to be solved by the present invention is to provide a rotor with a new structure, which makes the rotating water flow have an upward trend, so that the toilet paper is not easy to sink in the vortex and is completely decomposed by the shear force of water.

[0005] 2. In view of the above problems, the present invention proposes the following technical solutions:

[0006] 3. A truncated cone with a groove is fixed at the center of the upper surface of the disk, 6 triangular prisms are evenly inlaid on the upper surface of the disk, and 8 blades are evenly inlaid on the circumference of the disk.

[0007] 4. The diameter of the disc is 80-150mm, and the thickness of the disc is 5-20mm.

[0008] 5. There are 4 grooves engraved on the middle round table, and the inclination angles of the upper and lower end surfaces of the grooves are 5°-30°.

[0009] 6. The number of triangular prisms is 6, and the height of the triangular prisms is 5-20 mm.

[0010] 7. The number of blades is 8, and the inclination angle between the blade plane and the disc plane is 5°-25°.

[0011] 8. The beneficial effects of the present invention are as follows: the rotor can generate a relatively large vortex, increase the shear force of the water, and at the same time make the water flow have an upward trend, which can increase the dispersion of the sample paper and make the sample paper less likely to sink. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] In the figure: 1. disk, 2. cone, 3. triangular prism, 4. blade. DETAILED DESCRIPTION

[0014] The present invention is described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0015] like Figure 1 As shown, the present invention includes a disc 1, a truncated cone 2, a triangular prism 3, and blades 4. The rotor rotates with the motor, driving the liquid to rotate and generate a vortex. The blades, the inclined surfaces on the triangular prism, and the grooves on the truncated cone have a tendency to push the liquid upward, causing the liquid to move upward, so that the toilet paper sample in the liquid is not easy to sink, and the shear force of the water decomposes it, and the mechanical force of the rotor will not break the toilet paper sample. For those skilled in the art, improvements or changes can be made according to the above description, and all these improvements and changes should fall within the protection scope required by the present invention.
