Abstract

The utility model relates to a drying roller, including the cylinder, set up near the water conservancy diversion awl roller feeding end, match the flight that sets up at the cylinder inner wall, it is regional that the flight matches the vertical middle part that sets up at the cylinder, and the flight is followed the feed end and is extended to the discharge end on the cylinder inner wall, and the flight is from the cylinder inner wall to the certain angle of inside the drum centrally -inclined. The utility model discloses can improve drying roller's packing rate, make the dwell time of material in drying roller increase reduction in production cost.

Description

A kind of drying roller

Technical field

The utility model relates to plant equipment, particularly relates to a kind of drying roller.

Background technology

At present, make in industry in oven dry, the seed output and quality after drying materials will be directly had influence on for the drying rate speed of raw material in drying roller and time of staying length, so in order to the product quality that controls material drying and output, reduce the production cost of drying in production process, embodying the advance of drying plant and the standard of practicality is exactly see the drying rate of material in cylinder and the time of staying.

In the design of real drying plant, the main method improving drying rate has several as follows: 1. improve the temperature in drying roller, but due to the restriction by material carburizing temperature, maximum temperature is fixing, cannot improve drying rate by temperature raising.2. increase the heat exchange area of material, namely at drums inside, lifting flight is installed accordingly, in cylinder, form material curtain reach the object increasing heat exchange area.The time of staying of material in cylinder is when having drum rotation speed cylinder to install and the angle of horizontal plane inclination angle and lifting flight determines jointly.

Along with the development of drying industry, to fixed more and more lower of the standard of moisture content of material after drying, material so relatively, also go Free water to become baking by original baking and remove Free water and part free water, so just cause when actual drying plant design for reaching moisture content standard, by lengthening cylinder or falling low-producing method to realize.This just directly increases the investment of production cost of drying plant and runs production cost.

Summary of the invention

For the defect that prior art exists, the utility model proposes a kind of drying roller, the filling rate of drying roller can be improved, the time of staying of material in drying roller is increased, reduces production cost.

For achieving the above object, the utility model proposes a kind of drying roller, comprise cylinder, be arranged on the deflection cone near cylinder feed end, coupling is arranged on the flight of inner wall of rotary drum; Described flight coupling is arranged on the longitudinal middle area of cylinder, and flight extends along feed end to discharge end on inner wall of rotary drum, and flight is from inner wall of rotary drum to the centroclinal certain angle of drums inside.

The angle that described flight tilts is 15 to 30 degree.

Described flight is fixedly installed on the region of the close discharge end of cylinder.

Beneficial effect:

The utility model is by being arranged on deflector in cylinder and flight, make material to be taken up the direction of shedding contrary with the direct of travel of material in cylinder, in cylinder, material flight material of kicking up while the cylinder tilted advances to discharge end is shed backward, so just slowed down the gait of march of material, cylinder filling rate is strengthened, the increased resident time of material in cylinder.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

1. discharge end, 2. flight, 3. feed end, 4. deflection cone, 5. cylinder.

Detailed description of the invention

In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.

As shown in the figure, a kind of drying roller, comprises cylinder 5, is arranged on the deflection cone 4 near cylinder 5 feed end 3, and coupling is arranged on the flight 2 of cylinder 5 inwall; Described flight 2 coupling is arranged on the longitudinal middle area of cylinder 5, and flight 2 extends along feed end 3 to discharge end 1 on cylinder 5 inwall, certain angle and flight 2 tilts from cylinder 5 inwall to cylinder 5 inside center.

The angle that described flight 2 tilts is 15 to 30 degree.

Described flight 2 is fixedly installed on the region of the close discharge end of cylinder 5.

The flight 2 i.e. reverse lifting flight that the utility model is arranged, exactly material is taken up the flight 2 that the direction of shedding is contrary with the direct of travel of material in cylinder 5, in cylinder 5, material flight 2 material of kicking up while the cylinder 5 tilted advances to discharge end 1 is shed backward, so just slowed down the gait of march of material, cylinder 5 filling rate is strengthened, the increased resident time of material in cylinder 5, this project organization is very rationally suitable for, and manufacture craft is simple, and it is excellent as follows:

1., when roller tube does not lengthen, make the increased resident time of material in cylinder.

2. device fabrication cost and production run cost do not increase.

3. the capacity and output of equipment remains unchanged.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
