The operation of the present invention having the above-described structure will be described with reference to FIGS. 1 to 7. FIG.

3, when the pulverizing object is to be pulverized by using the pulverizing apparatus 1 according to an embodiment of the present invention, the pulverizing apparatus 30 is installed in a hinged manner in front of and behind the pulverizing device 30, The grinding drive unit 10 and the blower unit 50 are rotated about the hinge 5 to be closed.

When the crushing drive unit 10 is hingedly closed, the scraping impeller 17 and the rotary cutter 16 provided on the rear side of the crushing drive unit 10 are inserted into the crushing cylinder unit 31 of the crushing unit 30 The blower housing 55 provided on the front side of the blower unit 50 comes into contact with the rear surface of the blower unit 33. [

In this state, the hooking hole 61 of the locker 60 is engaged with the hooking part 63 provided on the free end of the blower bracket 51, The hook 62 is pulled toward the crushing drive unit 10 and the blower bracket 51 and the actuator bracket 11 are pulled toward the crushing drive unit 10, The free end portion of the second end portion is locked.

At this time, the cutter plate 15 provided on the rear side of the driver bracket 11 is pressed against the opened front side of the crushing cylinder unit 31 to close the open space of the crushing cylinder unit 31, The front surface of the blower housing 55 installed on the front side is pressed against the rear surface of the discharge pipe 33 and the rear of the taper hole 32 inside the discharge pipe 33 is closed.

As shown in FIGS. 2 and 4 and 5, the mesh 35 and the ring-shaped surface cutter 36 are sequentially inserted into the engagement step portion 34 formed at the front of the taper hole 32, The front and rear portions of the crushing unit 30 are closed by the crushing drive unit 10 and the blower unit 50, do.

An inner cutter portion 38 is formed on the inner peripheral edge of the crushing cylinder unit 31 in front of the net 35. A rotary cutter 16 and a scraping impeller 17 are inserted into the inner space, The inner space of the unit 31 is filled with the material to be ground (ground object) contained in the hopper 6 through the hopper 6, the inlet pipe 7, the inlet port 11a, 31).

In this state, when the motor 12 installed in the crushing drive unit 10 is driven, the rotary cutter 16 inserted into the crushing cylinder unit 31 and the scraping impeller 17 rotate, The rotary cutter 16 is primarily wound in a direction perpendicular to the motor shaft and a scraping impeller 17 is provided on the rear side of the rotary cutter 16 A small amount of the pulverized object to be crushed by the impact of the rotary cutter 16 is thrown to the inner circumferential surface side of the pulverizing cylinder unit 31.

At this time, the inner cutter portion 38 formed in the inner peripheral surface of the pulverizing cylinder unit 31 is formed, and the pulverized object is further broken in the process of hitting the inner cutter portion 38, A small piece of the object to be ground located between the end of the inner cutter portion 38 and the inner cutter portion 38 is cut by the cutting edge of the rotating rotary cutter 16 and the fixed inner cutter portion 38, 31 are crushed while being brought into contact again with the surface cutter portion 13 having the surface formed in the form of a wash plate and the ring-shaped surface cutter 36. In the course of repeating this process, And pulverization is performed.

When the pulverizing object is crushed in the inner space of the pulverizing cylinder unit 31 as described above, the blowing fan 53 rotates inside the fan housing 55 at the rear side of the net 35, A suction force for sucking the powder to be pulverized in the inner space of the fan housing 55 side is applied.

In this state, the ground particles smaller than the holes of the mesh 35 are sucked into the taper holes 32 of the discharge pipe 33 through the holes of the mesh 35, and the discharge pipe 33 and the blower housing 55 And the air is discharged to the outside through the discharge portion 54 of the blower housing 55.

In the process of passing the finely pulverized pulverized particles through the pulverizer 35, there is a phenomenon that the pulverized particles adhere to the front side of the pulverizer 35 due to moisture, viscosity, The scraping impeller 17 provided at the rear of the rotary cutter 16 is bent at a predetermined angle to the mesh side of the scraping impeller 17 so that the scraped impeller 17 generates wind during the rotation of the scraper impeller 17, And the pulverized particles dispersed by the suction force by the blowing fan 53 pass through the net 35.

The end of the wing which is bent in the scraping impeller 17 rotates with a fine gap with the front surface of the mesh 35 to push out the crushed particles to be stuck on the mesh 35 The sticky part of the net is scraped off.

After the pulverizing operation for the pulverized object is completed, the supplied power is cut off to stop the motor 12 of the pulverizing and driving unit 10 and the motor 52 of the blower unit 50, The grinding drive unit 10 and the blower unit 50 provided hingedly in front of and behind the grinder unit 30 can be opened as shown in FIG. 3 (B).

As the grinding drive unit 10 and the blower unit 50 are opened, the scratching impeller 17 including the rotary cutter 16 of the grinding drive unit 10 and the front and rear parts of the grinder unit 30, So that the cleaning can be performed easily.

4 and 5, the crusher 30 includes a cooler 44 constituting the crusher 30, a crusher main body 40, a ring cutter 36, a mesh 35 ) Can be easily separated, so that each component can be easily cleaned, so that the powder can be hygienically produced.

4 and 6, a plurality of rows of cooling water grooves 41 are formed on the outer circumferential surface of the crusher main body 40, a cooler 44 is fitted to the outside of the cooling water grooves 41, An inlet port 42 and a drain port 43 through which the cooling water is introduced and drained, respectively, so that the pulverizer main body 40 can be cooled by water cooling.

By cooling the crusher main body 40 whose temperature has been raised by the heat generated during the crushing process with the cooling water, the life of the crusher main body 40 is extended, and in the case of the crushing material having a viscosity, It is possible to improve the grinding efficiency.

The cooler 44 is provided with an inlet port 42 and a drain port 43 so as to be opposed to the cooling water groove 41 at an obtuse angle so that cooling water can be smoothly introduced and drained.
