Abstract

The utility model discloses a coarse material screener for citric acid production, which comprises a support (1), a box (2), a screen net (8), a feeding port (7) and a fine material discharging port (11). A positioning plate (3) is arranged on the outer wall of the lower portion of the box (2), and the bottom of the positioning plate (3) is arranged at the upper portion of the support (1) through a spring (4). A connecting plate (5) is fixed on top of the box (2) and fixedly connected with a vibrational fluidized bed for drying materials. A material separating box (9) is arranged on the side wall of the box (2), the bottom of the material separating box (9) is provided with a coarse material discharging port (10), and a bottom panel of the material separating box (9) is connected with the lower end of the screen net (8). The coarse material screener for the citric acid production performs rough sizing in advance before the material requiring to be screened is put into a flat vibrating screen or a round vibrating screen, thereby avoiding damages caused by large block of materials on the flat vibrating screen or the round vibrating screen. In addition, the coarse material screener for the citric acid production is simple in structure, convenient to use, easy to operate and not easy to damage.

Description

Citric Acid Production coarse fodder screening washer

Technical field

The utility model relates to the equipment that a kind of Citric Acid Production is used, and specifically a kind of Citric Acid Production coarse fodder screening washer is applied to material and enters flat shake sieve or round sieve the roughly selecting chunk products before of shaking.

Background technology

In Citric Acid Production; material is in crystallizing evaporator after the crystallization; after in crystallizer, mass transport to centrifuge being carried out Separation of Solid and Liquid with pump; solid enters oven dry in the vibrated fluidized bed; oven dry back material directly enters flat shake sieve or the circle sieve that shakes by the discharging opening of vibrated fluidized bed and carries out the fine screen branch; entering the interior finished product by different meshes of automatic packaging machine after the screening again loads in mixture; its weak point is: owing to directly carry out fine screen; shortened the service life of fine screen screen cloth; changing screen cloth shuts down again; so just influence the continuous production of citric acid, reduced production efficiency.

Summary of the invention

The purpose of this utility model is to provide a kind of simple in structure, easy to use, easy to operate, not fragile, round sieve or flat sieve screen cloth Citric Acid Production coarse fodder screening washer in service life that shakes of shaking of prolongation.

In order to reach above purpose, the technical scheme that the utility model adopted is: this Citric Acid Production coarse fodder screening washer, comprise support, casing, screen cloth, charging aperture and fines discharging opening, on the top board of casing, be provided with charging aperture, be provided with the fines discharging opening in the bottom of casing, screen cloth is fixed in the casing chamber, it is characterized in that: on the outer wall of lower box, be provided with location-plate, the bottom of location-plate is located at the top of support by spring, the top of casing is upper junction plate fixedly, connecting plate is fixedlyed connected with the vibrated fluidized bed that the oven dry material is used, on the sidewall of casing, be provided with the sub-material casing, the bottom of sub-material casing is provided with the coarse fodder discharging opening, and the bottom panel of sub-material casing is connected with the lower end of screen cloth.

The utility model is also implemented by following measure: the top board of described casing is provided with peep hole.

The bottom panel of described sub-material casing and screen cloth are in a plane, and the angle of screen cloth and horizontal plane is 10---20 degree.

The beneficial effects of the utility model are: before the material of need screening enters flat shake sieve or the round sieve that shakes, use the utility model to roughly select in advance, coarse fodder is separated, fines then passes and carries out the fine screen branch after screen cloth enters flat shake sieve or the round sieve that shakes, having stopped bulk materials shakes sieve or justifies the damage that the sieve that shakes causes putting down, prolong the service life of the screen cloth of flat shake sieve or the round sieve that shakes, reduced maintenance frequency, and simple in structure, easy to use, easy to operate, not fragile.

Description of drawings

Fig. 1 is a structure cross-sectional schematic of the present utility model.

Among the figure: 1, support; 2, casing; 3, location-plate; 4, spring; 5, connecting plate; 6, peep hole; 7, charging aperture; 8, screen cloth; 9, sub-material casing; 10, coarse fodder discharging opening; 11, fines discharging opening.

The specific embodiment

Make the utility model with reference to accompanying drawing 1.This Citric Acid Production coarse fodder screening washer, comprise support 1, casing 2, screen cloth 8, charging aperture 7 and fines discharging opening 11, on the top board of casing 2, be provided with charging aperture 7, be provided with fines discharging opening 11 in the bottom of casing 2, screen cloth 8 is fixed in casing 2 chambeies, need the material of screening to put into casing 2 from charging aperture 7, after screen cloth 8 screenings, thin material flows out from the fines discharging opening 11 of casing 2 bottoms, it is characterized in that: on the outer wall of casing 2 bottoms, be provided with location-plate 3, the bottom of location-plate 3 is located at the top of support 1 by spring 4, the top of casing 2 is upper junction plate 5 fixedly, connecting plate 5 is fixedlyed connected with the vibrated fluidized bed that the oven dry material is used, the shaking force of using vibrated fluidized bed like this makes casing 2 do shock motion under the support of spring 4, do not increasing in addition under the situation of power, as long as vibrated fluidized bed work, casing 2 had both been worked thereupon, on the sidewall of casing 2, be provided with sub-material casing 9, the bottom of sub-material casing 9 is provided with coarse fodder discharging opening 10, the bottom panel of sub-material casing 9 is connected with the lower end of screen cloth 8, like this, casing 2 intracavity inter-connections on the inner chamber of sub-material casing 9 and screen cloth 8 tops, bulk materials after the screening enters sub-material casing 9 from the top of screen cloth 8, flow out from coarse fodder discharging opening 10 at last and enter care feed tray, dissolve utilization once more, fines then enters shake sieve or the flat sieve that shakes of circle by fines discharging opening 11 and carries out the dusting cover branch.

The top board of described casing 2 is provided with peep hole 6, when normally moving, is convenient to the check screening situation.

Described screen cloth 8 is made by the stainless steel round steel of 10 millimeters of diameters, and the length of side of square hole is 10 millimeters.

The bottom panel of described sub-material casing 9 and screen cloth 8 are in a plane, and screen cloth 8 is 10 with the angle of horizontal plane---20 degree.
