Description

Mixer apparatus for granulation molding {a mixer for granule adult form}

The present invention relates to a granulator-shaped mixer device for molding the powder injected into the rotating barrel into granules while the rotating barrel and the impeller installed therein are rotated in opposite directions.

In general, the devices for molding the powder into granules are mainly kneaded and extruded through small holes, cut into small sizes to produce granules, or injecting moistened powder and binder into the tank, and an impeller mounted at the bottom of the tank. The granules are made to rotate.

However, the molding apparatus for kneading powder to extrude and cut through small holes has a significant problem in mass production due to the complicated and time-consuming work process.

In addition, the device for forming a granulated powder of a mixture of appropriate moisture and binder by rotating the impeller built in the lower part of the tank is very demanding because the number of revolutions of the impeller and the mixing ratio of the moisture and the binder must be accurate. There have been closures such as deterioration in efficiency.

In particular, when the powder is rotated depending only on the rotational force of the impeller, the entire powder injected into the tank cannot be stirred evenly, resulting in a closed end that takes a considerable time for the stirring operation.

Therefore, since some of the powder is unmolded to remain in the powder state inside the tank, the defect rate generated during the molding of the granules was very high, and excessive time was required for the stirring operation, thereby significantly lowering the productivity.

The present invention has been made in view of the above-described problems, the object of which is to minimize the defect rate generated when molding the powder into granules, and to shorten the time required for the stirring operation for granule molding that can maximize the productivity of granules In providing a mixer device.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention for achieving the above object is as follows.

1 to 4, as shown in FIG.

An inclined surface 11 having a predetermined angle is formed at an upper portion of the supporting casing 10, and the rotating cylinder 20 is mounted on the inclined surface 11 so as to be inclined.

The drive shaft 22 fixed to the lower portion of the rotary cylinder 20 passes through the inclined surface 11 of the casing 10 and protrudes to the bottom thereof, and the drive shaft 22 is a drive mounted inside the casing 10. The motor 21 and the pulley and the belt are connected to each other to receive the power of the driving motor 21 so as to rotate the rotating cylinder 20.

The guide rod 41 is mounted on the inclined surface 11 so as to be inclined, and the guide rod 41 is inserted into the support tube 44 mounted on the inclined surface 11 to be stably supported. The top of the guide rod 41 is mounted with a rotary cylinder 20 cover 30 fixed to the frame 30a.

Rotating rod 31 penetrates and arranges the lid 30, and the rotary rod 31 is mounted on one side of the lid 30 so as to be eccentric.

The rotary rod 31 is connected to each other by a motor 32 mounted on one side of the frame 30a and a pulley and a belt so as to rotate the rotary rod 31 by receiving the power of the motor 32.

The lower part of the rotating rod 31 is equipped with a stirring impeller (31a), the impeller (31a) receives the power of the motor 32 in the opposite direction to the rotating cylinder 20 in the rotating cylinder (20) It is configured to rotate.

The lower side of the cover 30 is equipped with a scraper 33 is to be able to drop off the powder adhering to the side surface and the bottom portion of the rotating cylinder.

The reducer 41a is fixed to the outside of the guide rod 41 inserted into the support tube 44, and the pinion gear 42a is decelerated and rotated by the drive of the lever 43 to the support tube 44. The 42 is mounted so that the pinion gear 42a and the rack gear 41a are engaged with each other.

That is, the reduction gear 42 is attached to the outer side of the support pipe 44 attached to the inclined surface 11 of the casing 10, and the pinion gear 42a fixed to the shaft of this reduction gear 42 is guide rod ( The guide rod 41 is lifted from the support pipe 44 when the lever 43 of the reducer 42 is rotated by being engaged with the rack gear 41a fixed to the outer surface of the 41.

Therefore, when the lever 43 of the reducer 42 which is composed of a plurality of gears is rotated, the pinion gear 42a fixed to the shaft of the reducer 42 is rotated and the rack gear 41a engaged thereto is upward. It is pushed up and the guide rod 41 is raised.

At the same time, the cover 30 fixed to the upper side of the guide rod 41 is raised together, so that the upper portion of the rotating cylinder 20 is opened, thereby injecting or withdrawing powder into the rotating cylinder 20.

Operation of the present invention made of the above-described configuration is as follows.

That is, as the lever 43 of the tree 42 is rotated, the cover 30 fixed to the upper side of the guide rod 41 is raised, and the upper portion of the rotary cylinder 20 is opened. Inject the powder mixed with the appropriate moisture and the binder inside and close the cover 30 by lowering the guide rod 41.

In this state, by operating the drive motor 21 and the motor 32 to rotate the rotary cylinder 20 and the impeller 31a, respectively, the rotary cylinder 20 and the impeller 31a are rotated in opposite directions to each other Powders rotated in one direction inside the tradition 20 are eccentrically rotated on one side of the rotary cylinder 20 by the opposite direction of the impeller 31a, which is arranged and the impeller 31a and the rotary cylinder (which maintains a narrow gap). Between the inner walls of 20), they collide with each other, causing vortices to be formed into granules of small granules and discharged.

At this time, the rotating cylinder 20 is mounted to be inclined so that the entire powder injected into the rotating cylinder 20 is stirred evenly, and is operated by the operation of the rotating cylinder 20 and the impeller 31a which are rotated in opposite directions. Since the molding work of the granules is very efficient, most of the powders injected into the rotating barrel are molded into granules, which minimizes the defect rate that occurs during the molding work, and at the same time, the molding work of the granules can be completed. Productivity can be maximized.

In addition, the scraper 33 mounted on the lower side of the cover 30 is installed in close proximity to the inner wall and the bottom surface of the rotating cylinder 20 can effectively prevent the closed end of the powder is attached to the inner wall of the rotating cylinder 20. Since the stirring operation of the powder is so efficient that most of the powder can be molded into granules.

When the molding operation of the granules through the above-described process is rotated, the lever 43 of the reducer 42 is rotated so that the guide rod 41 and the cover 30 fixed on the upper side thereof are raised to the upper portion of the rotating cylinder 20. When opened, the molded granules inside the rotating cylinder 20 can be taken out.

The present invention as described above, injecting the powder mixed with the appropriate moisture and the binder into the inside of the rotary cylinder 20, by operating the drive motor 21 and the motor 32 to rotate the impeller 31a When the tradition 20 is rotated in the opposite direction to each other, the powder rotated in one direction in the interior of the rotating cylinder 20 causes a vortex between the impeller 31a and the inner wall of the rotating cylinder 20 to maintain a narrow gap. By constituting the granulator-shaped mixer device is discharged and formed into granules, by rotating the rotary cylinder 20 mounted to be inclined, the whole powder is rotated in the opposite direction while uniformly stirred, the rotary cylinder 20 and the impeller 31a Because the molding operation of the granules is made very efficiently, most of the powders injected into the rotary barrel are molded into granules, which minimizes the defect rate generated during granulation. Because the molding operation that can be completed within the time of the granules there are advantages, such as to maximize the productivity of the granules.
