Description
Technical field
The utility model relates to a kind of motor-vibro screen tool, exactly is a kind of multistage detection classifying screen.
Background technology
Iron and steel enterprise is when estimating the quality of raw material, and how much contained powder-particle object is an important indicator in the unit raw material.Powder-particle object in the raw material to be separated from raw material to calculate its content, need to use classifying screen, but, there is following problem in existing classifying screen, promptly the powder-particle object that filters out with existing classifying screen is impure, its reason is that each layer screen cloth in the existing classifying screen is by putting in order of its slot size: descending from top to bottom, the screen cloth that is the sieve aperture maximum comes the superiors, the sieve aperture minimum come orlop, therefore, the oarse-grained raw material of part can be ground into short grained powder-particle object after the multilayer screening in screening process, thereby increased the proportion of powder-particle object in raw material, made detection inaccurate.
Summary of the invention
The purpose of this utility model, provided a kind of multistage detection classifying screen, it can at first filter out short grained powder-particle object and detect use for people, can avoid part bulky grain raw material through being ground into powder-particle object after the screening layer by layer, the situation that powder-particle object proportion is increased takes place, and can make people obtain detecting more accurately data.
The purpose of this utility model is achieved through the following technical solutions: multistage detection classifying screen has four pillars, a spring is installed in every pillar upper end, four springs are connected with casing respectively, charging aperture is offered in the front upper place of casing, be provided with cavity in the casing, Powder screen is installed in the cavity, Powder screen is positioned at the charging aperture below, first-class flitch, first sieve and second flow material plate are installed in the casing from top to bottom successively, one end of first-class flitch, first sieve and second flow material plate is stretched out by the front portion of casing respectively, and vibrating motor is installed on the casing.
For further realizing the purpose of this utility model, can also realize by the following technical solutions: vibrating motor is installed in bottom of shell.Powder screen is connected and composed by screen frame and screen cloth, and a plurality of eccentric bolts are installed on the screen frame, and eccentric bolt cooperates the edge that compresses screen cloth with screen frame.Between eccentric bolt and screen cloth pad is installed.The dedusting mouth is offered at the casing top.
Good effect of the present utility model is: it installs the Powder screen that can filter out powder-particle object in the raw material below charging aperture, when screening, people can at first obtain the powder-particle object in the raw material, can calculate the proportion of powder-particle object in raw material exactly, can solve that existing classifying screen exists, because of the bulky grain raw material is ground into powder-particle object after screening layer by layer, powder-particle object is impure, the inaccurate problem of result of calculation and cause.Its vibrating motor is installed in the bottom of casing, makes casing front-rear reciprocation movement in up-down vibration, can strengthen the effect of screening.It also has advantage simple in structure, safe and convenient to use.
