Abstract

The utility model relates to a deflecting type far infrared grain drier. A deflecting grain path fixed on a support bracket is composed of a plurality of square barrel-shaped grain paths connected head-to-tail in a deflecting way. The square barrel-shaped grain paths are arranged along a slope. The upper end of the deflecting grain path is provided with a grain inlet and a heated steam outlet, and the lower end of the deflecting grain path is provided with a grain outlet. Far infrared radiating pipes are uniformly distributed on an upper wall in the grain path along the direction of the length of the grain path. As the utility model uses a far infrared heating way to dry grain, the utility model has the advantages of high heat efficiency and low energy consumption. As the far infrared radiating pipe is heated by using electricity, when drying is conducted, temperature is easy to control, heating efficiency of the far infrared is high, and the time for the grain staying in the grain path is short.

Description

Deflector type far infrared grain drier

The utility model relates to the heater and the grain flow passage structure of a kind of grain drier, particularly a kind of grain drier.

In the prior art, grain drier mostly is tower grain drier, and the grain runner of tower grain drier is the vertical food passageway made from two-layer vertical screen, and grain forms one deck grain wall in passage, and grain moves in passage from the top down; Heater is a coal-fired hot-blast stove, the exportable hot blast of coal-fired hot-blast stove.Allow hot blast blow over the grain wall when dry, realize heating, drying grain.This grain drier is when drying, and the complete machine thermal efficiency is low, and energy consumption is big, and heating-up temperature is not easy control.

The purpose of this utility model is in order to overcome above-mentioned deficiency, propose a kind of when drying control temperature, thermal efficiency height, grain drier that energy consumption is little easily.

The utility model is realized with the following method.

Deflector type far infrared grain drier has support, be fixed with the square tube shape food passageway that settle on the multistage slope on the support, the square tube shape food passageway that settle on the multistage slope from top to bottom, connect to form the baffling food passageway with the form of baffling from beginning to end, there are grain inlet and hot vapor outlet in the upper end of baffling food passageway, the baffling food passageway the lower end grain-export is arranged, the cross section of baffling food passageway is a rectangle; Upper wall in each section square tube shape food passageway, along the length direction of square tube shape food passageway, be evenly equipped with the far infrared wire spoke and penetrate pipe.

During use, penetrate the pipe energising to the far infrared wire spoke, allow the far infrared wire spoke penetrate pipe width of cloth in the baffling food passageway and penetrate far infrared, grain inlet in baffling food passageway upper end adds grain continuously, grain can be under the slope current of baffling food passageway, grain when the baffling food passageway flows down by FAR INFRARED HEATING, drying, flow out from the grain-export of baffling food passageway lower end then, the hot vapour that produces when dry can be discharged from the hot vapor outlet of baffling food passageway upper end.

The utility model adopts the method drying grain of FAR INFRARED HEATING, thermal efficiency height, and energy consumption is little, because penetrate pipe with the electrical heating far infrared width of cloth, so the temperature when dry is easy to control.

Below in conjunction with accompanying drawing, the utility model is further described.

Fig. 1 is the partial schematic sectional view of deflector type far infrared grain drier.

Among Fig. 1, deflector type far infrared grain drier has frame rack 1, the support 1 outer iron sheet outer casing 11 that is surrounded by.On the support 1, be fixed with baffling food passageway 2 from top to bottom, baffling food passageway 2 is to be connected to form by square tube shape food passageway 21 head and the tail that settle on three sections slopes, the cross section of square tube shape food passageway 21 is rectangles, there are grain inlet 22 and hot vapor outlet 23 in the upper end of baffling food passageway 2, there is grain-export 24 lower end of baffling food passageway 2, the upper wall in the square tube shape food passageway 21 that settle on each section slope of baffling food passageway 2, is fixed with the far infrared wire spoke along the length direction of square tube shape food passageway 21 and penetrates pipe 25.

Can be connected with fixing elbow between the head and the tail of the square tube shape food passageway that settle on the multistage slope of baffling food passageway 2, the gradient on the slope of the square tube shape food passageway that the fixing elbow of usefulness is connected is fixed.Also can be connected between the head and the tail of the square tube shape food passageway that settle on the multistage slope of baffling food passageway 2 with bell and spigot bend, the structure that bell and spigot bend is connected is the elbow 211 that decurved an angle of 90 degrees is arranged at the tail end of a last square tube shape food passageway, the angle coupling 212 that upward bent an angle of 90 degrees is arranged at the head end of next square tube shape food passageway, elbow 211 and elbow 212 all are sections of annulus, the bore of elbow 212 is greater than the bore of elbow 211, the axis of elbow 211 and elbow 212 place annulus coincides, elbow 211 can be inserted into 212 li at elbow, be that hinge joint links to each other between the head and the tail with two continuous square tube shape food passageway of bell and spigot bend, the axle 26 of hinge joint is fixed on the support 1, the axle 26 of hinge joint is on the axis of elbow 211 and elbow 212 place annulus, the gradient that links the slope of the square tube shape food passageway that links to each other with bell and spigot bend is adjustable, and the different gradients is applicable to the drying of different grains.

Be the flow velocity of restriction grain 2 li of baffling food passageway, the not elongated speed limit shelves bar 28 that becomes miter angle with the length direction of square tube shape food passageway is arranged at the bottom in each square tube shape food passageway 21.

When drying, smooth and easy for what grain in the baffling food passageway was flowed, on support 1, be fixed with vibrating motor 12, the vibration output shaft of vibrating motor 12 links to each other with each section square tube shape food passageway 21 bottom outward with lever 14 by connecting rod 13, the axle of lever 14 is fixed on the support 1, and vibrating motor 12 can pass to vibration the bottom of each section square tube shape food passageway 21 by connecting rod 13 and lever 14.

Hot vapour during for discharge drying in time in the baffling food passageway can be connected with air-introduced machine on hot vapor outlet 23.

The far infrared wire spoke is penetrated the power of pipe and can be controlled with the temperature controller in the control room 3, to regulate the temperature in the food passageway.

In order to improve the drying capacity of grain drier, can on support, settle two groups or more above-mentioned baffling food passageway.

Move for convenience and use, above-mentioned deflector type far infrared grain drier can be placed on the motor vehicle.
