Asphalt analysis instrument

Abstract

The invention discloses an asphalt analysis instrument which is characterized in that a rotor shaft is horizontally mounted in a machine cavity; the machine cavity is defined by an arc-shaped upper machine case and a rectangular lower machine case; a vibration exciter is connected with a perpendicular screening plate; the tangential direction of one end of a semi-circular screening plate leads toa feeding port; an automatic reset switch is positioned on the right side surface of the lower machine case; a microcontroller is arranged inside the lower machine case and positioned at the left sidepart of the lower end of the perpendicular screening plate; and a corrugated base is mounted on a base of the lower machine case. The asphalt analysis instrument has the beneficial effects that sincethe perpendicular screening plate and the semi-circular screening plate which continuously shake up and down are mounted in a hammer-type wet coal crusher, no high-moisture crushed product can adhereto the screening plates; furthermore, since all adhesive tape curtains are closely overlapped, no screened crushed product can adhere to the walls of the machine cases through the adhesive tape curtains; and through the asphalt analysis instrument, the restriction on the moisture of a material fed for being crushed can be prevented, the sample preparation process can be simplified, the sample preparation time can be shortened, and the working efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of analysis, in particular to an asphalt analysis instrument. Background technique [0002] Although there are many types of crushers used to prepare asphalt analysis samples, their common disadvantage is that they cannot crush wet coal. For example, for general-purpose gravel crushers, double-roll crushers, and gyratory crushers, if the moisture content of the crushed feed exceeds 8%, the feed port will be blocked, making it impossible to continue to operate. The same is true for the general hammer crusher. Although the moisture of the feed material can be crushed without restriction without a sieve grate, the particle size of the crushed product cannot meet the requirements; Block the feed inlet and the sieve holes on the sieve grate. Therefore, all factories and mines must dry or dry the samples before preparing large samples or other analytical samples, which takes a long time, which not only affects p...
