Abstract

PURPOSE:To achieve the stable operation of a machine by attaching a granulating cylinder to a drum in the vicinity of the center of gravity on the lower side of the drum. CONSTITUTION:A drum 2 having a vibration absorbing mechanism and having media such as balls received therein and a vibration generator 3 are attached to a support plate. The motor 11 driving the vibration generator 3 is arranged through a driving flexible joint 8 separately from the drum 2. The motor 11 is made synchronous to a timing transmission device 9 in order to intensify the movement of the media.A throwing-in port 1 of a material to be thrown in is provided to the blind plate part of the single side of the drum 2 or the upper part of the drum 2 and an end cover 6 having a discharge port having a large opening area provided to the entire periphery thereof so as to smoothly discharge the material to be thrown in is provided to the end of the drum on the side opposed to the throwing-in port. Further, a cylindrical or semicylindrical granulation cylinder 10 having necessary length and integrally vibrated along with a main body is arranged under the drum 2 so as to granulate or scrape off the material to be thrown in falling from the discharge port.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention adds a solidifying agent, water, etc. to dusts and fine powders, granulates from the kneading, chamfers, or removes the metal contained in the ash collected by a dust collector. It is very useful for environmental hygiene for handling by adding a solidifying agent and water to make a kneaded product that does not elute outside and granulating or shaving it.

[0002]

2. Description of the Related Art A vibrating mill is used as a kneading and granulating machine, in which an object to be charged is charged from one side of the drum and discharged from one end, and a cylinder or a semi-cylinder is arranged at one end of the drum at the discharge part. Granules are connected.

[0003]

However, the conventional technique lacks durability against vibration because the sizing cylinder is connected to one end of the drum. In order to lengthen the residence time for sizing, it is necessary to lengthen the sizing tube. To make it longer
There is a difference in the vibration at both ends of the drum length, and the durability against vibration is lacking. On the other hand, if the charging port is at one end or at the top, after charging the material to be charged, the material to be charged is pushed out by the medium in the drum and advances toward both ends in the longitudinal direction of the drum. The object to be charged, which has been discharged from the discharge port on one side but has proceeded to the other end side, is pushed toward the blind plate portion on the end side and cannot move. As a result, the material to be charged is pushed toward the charging port, and the charging cannot be performed smoothly.

[0004]

A sizing cylinder connected to one end of a drum is located below the drum, and a support plate on which the drum is attached, or a support is provided between the support plate and a spring, Attach using these. Further, there is a possibility that adhesion may occur by increasing the residence time. Therefore, the tilting angle of the sizing cylinder attached to the lower side of the drum can be arbitrarily adjusted. On the other hand, in order to be able to smoothly discharge the object to be charged into the drum,
A discharge port was provided at both ends of the drum to make it feasible.

[0005]

By attaching the sizing cylinder to the lower side of the drum, a longer sizing cylinder is attached instead of the short sizing cylinder as in the conventional technique, and continuous vibration operation becomes possible. In addition, by discharging both ends of the drum, it is possible to smoothly insert and discharge the object.

Embodiments of the present invention will be described with reference to the accompanying drawings. An electric motor 11 arranged on a pedestal 12, a timing transmission 9 and a vibration generator via a universal joint 8 for supporting the drum 2 by synchronously rotating the vibration generator, and the support plate 4 and the spring. The sieving cylinder 10 that is attached by utilizing the space between 5 and 5 is simultaneously oscillated with the drum 2. In FIGS. 1, 2, and 3, the material to be charged, which is charged from the charging port 1 of the drum 20, is kneaded by the medium filled in the drum 2 and discharged from the end cover 6 having a large opening area. , End cover 6
Is covered with a cover 7 to prevent it from falling outside. The input material discharged from the end cover 6 falls into the sizing cylinder 10, is sized or chamfered, and is discharged to the outside of the machine. At this time, in the case of the conventional technology, since the sizing cylinder is connected to the flange on the discharge side of the drum 2 by welding or the like, the sizing cylinder deviates from the mechanical balance and becomes separated from the center of gravity, and vibration fatigue occurs quickly.
Failures such as cracks are likely to occur. In this respect, the present invention compensates for this drawback by mounting the sizing cylinder near the center of gravity. It is also possible to make the sizing cylinder longer by taking advantage of this feature. 4, 5, and 6, the charging port 1 of the drum 2 is used as the central portion of the drum 2, and the discharging port is provided with end covers 6 having a large opening area at both ends. Be dropped into. In the case of discharging from one side of the drum, the material to be charged has a property of being kneaded in the drum and pushed in the longitudinal direction of the drum. Considering this property, a large amount of material is concentrated on the end side where there is no discharge port.
Providing outlets on both sides of the drum to eliminate this is the best approach.

[0007]

As described above, the material discharged from the drum of the vibrating mill can be stably operated by mounting the sizing cylinder firmly on the lower side of the drum. Further, by discharging from both ends of the drum, it is possible to perform stable continuous operation without filling the inside of the drum with the material being biased more than necessary.
