Abstract

The utility model discloses a transverse eight-groove inverted-cone-type drying cabinet, wherein a box (1) is divided into a group of a draft chamber (2) and a grain storage room (3) through a left and a right lateral hole plates (4, 5) and a mountain-shaped screen plate (6) on the top in the box body (1), and the draft chamber (2) and the grain storage room (3) are distributed in interval. The utility model is characterized in that the cross section of the draft chamber (2) is inversed cone shaped. The area of the mountain-shaped screen plate (6) of the inverted-cone-shaped draft chamber is comparatively bigger than the original mountain-shaped screen plate of the cone-shaped draft chamber, when grains drop into the drying cabinet from top to bottom, grains which drop on the mountain-shaped screen plate (6) drop into the grain storage room along the mountain-shaped screen plate (6), the weight of most of grains are supported by the mountain-shaped screen plate (6) of the inverted-cone-shaped draft chamber, pressure of grains to the left and the right lateral hole plates (4,5) is reduced, the life span of the screen plate is improved, ventilating capability is reinforced, and service performance of equipment is improved.

Description

Horizontal eight groove back taper formula drying boxes

Technical field

The utility model relates to the drying box in the full-automatic closed low temperature circulation dryer that is applied to grain drying, is specifically related to horizontal eight groove back taper formula drying boxes.

Background technology

Foodstuff drying device is with the air heat drying by burner, dry air after air exhauster will heat is as transmitting in the wet switch of doing of medium suction porous, grain then is delivered into from last and cocycle by conveyer and does wet switch and carry out with dry hot-air that heat is wet to be exchanged, moisture content in the grain of exchange back is constantly discharged outdoor by air exhauster through special-purpose air channel again, grain is dry frontier inspection survey through online moisture content automatic tester limit, when reaching target moisture content or stoving time, burner and air exhauster successively stop heating and exhausting, and the cooling naturally of finishing cereal reaches the oven dry purpose.

At present, the drying box of doing the positive bevel-type of installation in the wet switch of foodstuff drying device, this drying box chevron web plate by left and right sides orifice plate and top in casing is divided into one group of airflow chamber and grain storage chamber with casing, airflow chamber and grain storage interventricular septum distribute, the airflow chamber cross section is positive taper, when grain fell into drying box from top to bottom, part grain at first dropped on the chevron web plate at airflow chamber top, falls into the grain storage chamber through the chevron web plate along the left and right sides orifice plate then; Because the cross section, web plate hole of airflow chamber is positive bevel-type, so grain is bigger to the pressure of mesh plate, cause mesh and easy to wear, in order to increase the service life, adopt the material of thickening mesh plate or change mesh plate, so not only increase manufacturing cost, also strengthened difficulty of processing, reduced performance of ventilating.

Summary of the invention

The purpose of this utility model is: a kind of horizontal eight groove back taper formula drying boxes are provided, and this drying box is rational in infrastructure, has made the life-span long, and performance of ventilating is good.

Technical solution of the present utility model is: the chevron web plate by left and right sides orifice plate and top in casing is divided into one group of airflow chamber and grain storage chamber with casing, and airflow chamber and grain storage interventricular septum distribute, and it is characterized in that: the cross section of airflow chamber is back taper.

The chevron web plate area of back taper airflow chamber is relatively greater than the chevron web plate of positive taper airflow chamber, when grain falls into drying box from top to bottom, the grain that drops down onto on the chevron web plate falls into the grain storage chamber along the chevron web plate, the chevron web plate of the relative increase area of back taper airflow chamber has born most grain weight, reduced the pressure of grain to the left and right sides orifice plate, improve mesh plate service life, strengthened venting capability, improved the serviceability of equipment.

Among the figure: 1. drying box casing, 2. airflow chamber, 3. grain storage chamber, 4,5. left and right sides orifice plate, 6. chevron web plate.

The specific embodiment

Shown in Fig. 5-8, the chevron web plate 6 by left and right sides orifice plate 4,5 tops in drying box casing 1 is divided into one group of airflow chamber 2 and grain storage chamber 3 with casing 1, and airflow chamber 1 and grain storage chamber 3 are spaced apart, it is characterized in that: the cross section of airflow chamber 2 is back taper.

Chevron web plate 6 areas of back taper airflow chamber are relatively greater than the chevron web plate of former positive taper airflow chamber, when grain falls into drying box from top to bottom, the grain that drops down onto on the chevron web plate 6 falls into grain storage chamber 3 along chevron web plate 6, the chevron web plate 6 of back taper airflow chamber 2 has born most grain weight, reduced the pressure of grain to left and right sides orifice plate 4,5, improve mesh plate service life, strengthened venting capability, improved the serviceability of equipment.

Claims

1. horizontal eight groove back taper formula drying boxes, chevron web plate (6) by left and right sides orifice plate (4,5) and top in drying box casing (1) is divided into one group of airflow chamber (2) and grain storage chamber (3) with casing (1), airflow chamber (1) and grain storage chamber (3) are spaced apart, it is characterized in that: the cross section of airflow chamber (2) is back taper.
