Asphalt analysis instrument

Abstract

The invention discloses an asphalt analysis instrument. A rotor shaft is horizontally installed in a machine cavity formed by an arc-shaped upper machine shell and a rectangular lower machine shell. Avibration exciter is connected with a vertical sieve plate. The tangential direction of one end of a semicircular sieve plate straightly extends to a feed inlet. An automatic reset switch is locatedon the right side face of the lower machine shell. A single chip microcomputer is arranged in the lower machine shell and is located on the left side portion of the lower end of the vertical sieve plate. A corrugated base is installed on a base of the lower machine shell. According to the asphalt analysis instrument, the vertical sieve plate and the semicircular sieve plate which shake up and downceaselessly are installed in a hammer type wet coal crusher, so that high-moisture crushed products do not adhere to the sieve plates. All rubber strip curtains are in lap joint tightly, so that thesieved crushed products do not adhere to a machine shell wall through the curtains, through the asphalt analysis instrument, moisture of crushed fed materials is not limited, sample preparation procedures are simplified, sample preparation time is shortened, and work efficiency is 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...
