Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an improvement of the muller foil mechanism of a kneader.

(Prior Art) Conventionally, as one type of kneading machine, two maller foils that can rotate horizontally are horizontally rotated in a cylindrical kneading tank with a bottom by rolling them on the inner surface of the side wall of the kneading tank. Some kneading machines are configured to knead powder and granular materials using this method, but in kneading machines configured in this way, the kneading machine uses a kneading machine that allows the kneading process to occur through an annular gap formed between the muller foil and the roller that rotatably supports the muller foil. There were problems such as direct intrusion of particulate matter and premature wear of the bearings that rotatably support the rollers.

(Purpose of the invention) The invention was made with the aim of solving the above problems.

(Structure of the invention) Reference numeral 1 denotes a support shaft attached to the upper end of a drive rotating shaft (not shown) rotatably disposed in the center of a kneading tank (not shown). A short cylindrical roller 2 is mounted at an eccentric position so as to be horizontally rotatable via a bearing (not shown). The roller 2 is provided with a mullet foil 3 in the shape of a canopy, and its center portion is attached to the upper end of a vertical rotation shaft (not shown) rotatably provided at the center of the roller 2 via a bearing (not shown). The mullet foil 3 is fixed and mounted on a crown, so that the mullet foil 3 is configured to be horizontally rotatable via a vertical rotation shaft (not shown). Further, an annular inner liner 4 and an annular outer liner 5 each having a flange at the lower end are fitted on the outer circumferential surface of the roller 2 and the inner circumferential surface of the mallet foil 3, respectively. It makes up the department. Further, the lower surface level of the inner liner 4 is formed slightly lower than the lower surface level of the outer liner 5, and the lower surface of the inner liner 4 has the above-mentioned gap 6.
A hollow disc-shaped shielding plate 7 that closes the lower end is attached to the lower surface of the outer liner 5 with a slight gap therebetween. Furthermore, a tire 8 is fitted onto the outer peripheral surface of the malt wheel 3.

(Function of the invention) In the device configured as described above, when the roller 2, the muller foil 3, etc. are horizontally rotated in a kneading tank (not shown) with a driving rotation shaft (not shown), the roller 2, the muller foil 3, etc. are subjected to centrifugal force. generated and horizontally rotated inward to the side wall of the kneading tank using the support shaft 1 as a fulcrum,
The tire 8 comes into contact with the inner surface of the side wall of the kneading tank, and the muller foil 3 and tire 8 roll on the inner surface of the side wall to knead the powder, but since the lower end of the gap 6 is closed by the shielding plate 7, Particles do not enter through the gap 6.

Although the shielding plate 7 is attached to the inner liner 4 in the above embodiment, it may be attached to the lower surface of the outer liner 5 with an appropriate distance from the lower surface of the inner liner 4.

(Effect of the invention) In this invention, the lower end of the annular gap formed in the sliding part between the roller and the muller foil is closed with a shielding plate, so that powder and granules directly enter through the gap during kneading. Therefore, the life of the bearing is significantly extended, which is an excellent practical effect.
