Abstract

The utility model relates to a material lifting board. The material lifting board comprises a board body with two bends arranged in sequence in the same direction, wherein the board body is divided by the two bends into a first face board, a second face board and a third face board, which are connected in sequence; and the third face board is trapezoid-shaped, and one side of the long bottom edge of the trapezoid-shaped third face board is connected with the second face board. Since the material lifting board has the trapezoid-shaped third face board, after the material lifting boards are placed inside the drying drum, the materials are thrown between two adjacent material lifting boards in the form of continuous material curtain during the operation, thereby increasing the contact area between the materials and the hot air, promoting moisture removal, improving the drying efficiency and reducing the energy consumption of the drying machine.

Description

A kind of lifting blade

Technical field

The utility model relates to a kind of lifting blade, particularly a kind of interior lifting blade of oven dry tube that is used for rotating drum type drying machine.

Background technology

Rotating drum type drying machine is that manufacturing enterprises such as present building materials, metallurgy are used for capital equipment that material is dried.Its operation principle is by the lifting blade in the oven dry tube that is arranged at dryer, in oven dry tube rotating process material is taken to certain altitude and sheds down from the oven dry tube bottom, material is contacted with hot gas, thereby reach the purpose of dried material.Existing lifting blade as shown in Figure 1, 2, it is that steel plate 4 by a rectangle forms through twice bending, formed first panel 1, second panel 2 and the 3rd panel 3 that connect in turn through this rectangular steel plates after twice bending, by bolt angle steel 5 has been installed in the outside of first panel.The lifting blade of this structure has characteristic of simple structure, but, because the 3rd panel 3 is equally also to be rectangular configuration, this just causes the material hoisting depth limited, material is shed the position and is concentrated, is difficult to form continuous material curtain, the contact area of material and hot gas is less, causes that drying efficiency is low, energy consumption is high, can not satisfy the requirement of energy-saving and emission-reduction.

The utility model content

The technical problems to be solved in the utility model is to overcome existing defective, and a kind of lifting blade that can effectively improve drying machine drying efficient, reduce the dryer energy consumption is provided.

In order to solve the problems of the technologies described above, the utility model provides following technical scheme: a kind of lifting blade, comprise in turn at the plate body that upwards has two bendings together, described two bendings are separated into plate body first panel, second panel and the 3rd panel that connects in turn, being shaped as of described the 3rd panel is trapezoidal, and long base one side of this trapezoidal shape the 3rd panel is connected with second panel.

Described trapezoidal be right-angled trapezium.

Angle between described first panel and the 3rd panel is the obtuse angle.

Angle between described first panel and the 3rd panel is between 95 ° and 105 °.

The outside of described first panel is installed with installed part.

Described installed part is the angle steel that is bolted on first panel.

Lifting blade of the present utility model is because its 3rd panel is a trapezium structure, after in this lifting blade is arranged at the oven dry tube, when work, the material of shedding downwards between the two adjacent lifting blades can form a continuous material curtain, enlarged the contact area of material and hot-air like this, help separating out of moisture, improved drying efficiency, reduced the energy consumption of dryer.

Angle between first panel and the 3rd panel is the obtuse angle, is convenient to material like this and lifting blade is separated, and helps shedding uniformly material to be dried downwards.

The specific embodiment

Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in qualification the utility model.

Embodiment 1

Shown in Fig. 3,4, the embodiment of a kind of lifting blade of the utility model, comprise one in turn at the plate body 8 that upwards has two bendings together, two bendings wherein are separated into plate body first panel 7, second panel 9 and the 3rd panel 10 that connects in turn, wherein the 3rd panel 10 be shaped as trapezoidal, the structure of this trapezoidal employing right-angled trapezium in the present embodiment, long base one side of this trapezoidal shape the 3rd panel 10 is connected with second panel 9.For the ease of evenly shedding of material, the angle between first panel 7 and the 3rd panel 10 is the obtuse angle, and preferred angular range is between 95 ° and 105 °, and the angle that adopts in the present embodiment is 100 °.For the ease of this lifting blade being installed in the oven dry tube, by bolting two angle steel 6 are arranged in the outside of first panel 7, bolt is not shown among the figure, can certainly adopt the mode of welding angle steel 6 to be fixed in the outside of first panel 7.

It should be noted that at last: the above only is preferred embodiment of the present utility model, be not limited to the utility model, although the utility model is had been described in detail with reference to previous embodiment, for a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
