Problems solved by technology
[0002] At present, the test object of the viscometer used to test the slurry viscosity is mainly suspended slurry or fine-grained slurry, such as cement slurry, etc. These instruments are not suitable for the coarse aggregate slurry used in mine filling; With the rapid development of the mining industry in recent years, resources in some areas are almost exhausted, and the mining depth is gradually increased. Filling mining is gradually widely used, and coal gangue, as waste generated by coal mining, is also gradually being used; The filling technology of the material is being researched and applied, and the gangue in it can reach 5-20mm at most. For these filling slurry containing coarse particles, it is difficult to test the viscosity of the slurry

Abstract
The invention discloses a gangue fly ash slurry apparent viscosity testing device and a testing method thereof. The gangue fly ash slurry apparent viscosity testing device comprises a base; a soybean milk containing barrel fixedly mounted on the top end surface of the base; a support, wherein the bottom end of the support is fixedly connected to the top end face of the part, located on the left side of the soybean milk containing barrel, of the base; a direct current motor fixedly mounted on the bracket; and a rotary testing assembly, wherein the top end of the rotary testing assembly is in driving connection with the driving end of the direct-current motor, and the bottom end of the rotary testing assembly extends into the inner cavity of the slurry containing barrel. The device disclosed by the invention is convenient to test, low in cost and capable of testing the apparent viscosity of the gangue fly ash slurry with the gangue particle size of 5-20mm.
Description
technical field [0001] The invention specifically relates to the technical field of a gangue fly ash slurry apparent viscosity testing device, in particular to a gangue fly ash slurry apparent viscosity testing device and a testing method thereof. Background technique [0002] At present, the test object of the viscometer used to test the slurry viscosity is mainly suspended slurry or fine-grained slurry, such as cement slurry, etc. These instruments are not suitable for the coarse aggregate slurry used in mine filling; With the rapid development of the mining industry in recent years, resources in some areas are almost exhausted, and the mining depth is gradually increased. Filling mining is gradually widely used, and coal gangue, as waste generated by coal mining, is also gradually being used; The filling technology of the material is being researched and applied, and the maximum size of gangue is 5-20mm. For these filling slurries containing coarse particles, it is diffic...
