Description

Be applied to extrusion device of straw granulation machine

Technical Field

The utility model relates to a granulation machine equipment technical field specifically is a be applied to extrusion device of straw granulation machine.

Background

The straw granulator is a granular fuel forming machine which takes agricultural wastes such as corn straws, rice straw straws, sawdust, wood powder, wood chips and the like as raw materials, and granules made by the machine can be used for fireplaces, boilers and biomass power plants. The straw granulator passes through pinch roller and mould high-speed rotation, carries out extrusion friction to the raw materials of work intracavity, makes the raw materials obtain the shaping, and the raw materials need not to add any additive or binder in the course of working, and the high density granule stick that forms through the compression of granulator burns more fully, the combustion value is higher, and the pollutant emission is low after just burning, is a cleaner energy also the new forms of energy that the country advocated. Among the prior art, the straw granulation machine passes through pinch roller and mould high-speed rotation, carries out extrusion friction to the raw materials of work intracavity, makes the raw materials obtain the shaping, but the effect is not ideal in actual work in-process, has the raw materials shaping difficulty, and the pinch roller can take place to hold the phenomenon of expecting in the mould, has seriously influenced production efficiency and product quality, puzzles the manufacture factory always.

SUMMERY OF THE UTILITY MODEL

In view of the defects in the prior art, the utility model aims to provide an extrusion device applied to a straw granulator.

In order to solve the technical problem, the utility model discloses a following technical scheme: the utility model provides an extrusion device for straw granulation machine which characterized in that: the hydraulic lifting device is arranged at the top of the shell and connected with the extrusion plate, the rolling die A and the rolling die B are arranged in the middle of the shell and respectively comprise a forming die, a support, a rolling shaft and a compressed air chamber, a forming hole and an extruding air hole are uniformly formed in the forming die, a check valve is arranged between the forming hole and the extruding air hole, the compressed air chamber is connected with an external compressed air device, and the rolling shaft is driven by an external motor.

As a further improvement of the utility model, the extrusion plate is in close contact with the inner wall of the shell.

As a further improvement of the utility model, the diameter of the forming hole is larger than that of the extruding air hole.

As a further improvement of the utility model, the forming holes on the rolling die A and the rolling die B are corresponding.

Compared with the prior art, the utility model discloses the beneficial effect who has does: the utility model discloses a rolling die A, rolling die B are to pressing, the theory of operation of each other crowded, except having rotatory rolling compression function, have still increased the stripper plate and have forced the extrusion function, then compressed air is by crowded material air hole back-up check valve with the fashioned material blowout of shaping hole, the shaping is easy, efficient, convenient to use, easy and simple to handle.

Drawings

The invention will be further described with reference to the accompanying drawings and specific embodiments:

FIG. 1 is a schematic structural view of an extrusion device applied to a straw granulator of the present invention;

in the figure: the device comprises a shell 1, a bin 2, a rolling die A3, a rolling die B4, a forming hole 5, a check valve 6, a material extruding air hole 7, a compressed air chamber 8, a forming die 9, a support 10, a rolling shaft 11, a hydraulic lifting device 12, a squeezing plate 13, an air outlet 14 and a discharge hole 15.

Detailed Description

In order to make the technical solution and the advantages of the present invention more clear and more obvious, the present invention is further described in detail with reference to the accompanying drawings and the specific embodiments, it should be understood that the specific embodiments described herein are only used for understanding the present invention, and are not used for limiting the present invention, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention.

When the material pressing device is used, the raw materials are fed through the stock bin 2, when the raw materials are fed, the hydraulic lifting device 9 drives the extrusion plate 13 to descend to realize extrusion, the speed reducer is driven by the motor and drives the rolling die A3 and the rolling die B4 to move relatively, the extrusion plate 13 extrudes the materials into the forming hole 5, the materials in the forming hole 5 are compacted and formed under the action of the check valve 6, the forming holes 5 on the rolling die A3 and the rolling die B4 correspond and can be further compacted and formed, when the rolling die A3 and the rolling die B4 are separated at the lower part, as the compressed air chamber 8 is filled with the compressed air, the compressed air pushes the check valve 6 to eject the materials formed in the forming hole 5 through the extrusion air hole 7 under the effect of no external pressure, the utility model adopts the working principle of the rolling die A3 and the die B4 for pressing and mutual extrusion, besides the function of rotary rolling and compression, the extrusion plate 13 is additionally provided with a forced extrusion function, then compressed air jacks the check valve 6 through the extrusion air hole 7 to spray out the materials formed in the forming hole 5, and the forming is easy, the efficiency is high, the use is convenient, and the operation is simple and convenient.
