Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an apparatus for mixing two or more raw materials used in dry-formed tiles, and particularly to an apparatus suitable for large-capacity use.

Prior Art and Problems to be Solved by the Invention Conventional tile raw material mixing equipment, like a ready-mixed concrete mixer, supports a barrel with an oblique rotating shaft so that it can rotate freely at one end of the shaft, and supports the barrel at the other end. The barrel has a structure with an input port that also serves as a discharge port, and the cantilever support makes it difficult to increase the size.Also, the raw materials fed into the barrel are asymmetrical and unbalanced, making high-speed rotation difficult. Moreover, since the discharge port and the input port are also used, there is a drawback that it takes time to input and discharge raw materials and to clean the inside.

Means for Solving the Problems As a means for solving these problems, the present invention provides barrels having a conical shape that decreases in diameter from a large diameter portion at the center toward both left and right ends, protruding from both left and right ends. The barrel is supported by a horizontal shaft that rotates freely, and the barrel is connected to a rotation drive device, and the barrel has stirring blades protruding from the inner circumferential surface, and the large-diameter portion of the barrel is provided with an inlet that can be opened and closed at opposing positions. It has a configuration with an opening and an outlet.

Alternatively, a vibrator may be attached near the outlet of the barrel of the mixing device having the above configuration.

Functions and Effects of the Invention The present invention has the above-mentioned structure, and since the rotation axis of the barrel is held horizontally and supported at both left and right ends, it is possible to stably support large and large-capacity items, and also to make it possible to stably support large-sized and large-capacity items. Since the raw materials are symmetrical around the large diameter section, they are well-balanced and can be rotated at high speeds, allowing mixing in a short time.Therefore, there is no destruction of mixed particles, and the material is fed into the corresponding position of the large diameter section. The provision of an opening and a discharge port makes it possible to input and discharge raw materials and clean the inside in a short time.Furthermore, since the barrel has a double conical shape and the discharge port is provided in the large diameter part, the inside of the barrel can be cleaned easily. This has the effect of shortening the discharge time because the raw material quickly slides down toward the discharge port. In addition, by attaching a vibrator near the discharge port of the barrel, the sliding speed of the raw material can be increased and the discharge time can be further shortened.

Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings.

In the figure, 1 is a barrel with a conical shape that decreases in diameter from the large diameter part at the center toward both left and right ends,
Horizontal shafts 2, 2 protruding from both left and right ends of the bearing 3,
A large gear 4 fixed to one side of the outer periphery meshes with a small gear 5 fixed to the output shaft of a motor 5. It is designed to rotate by the drive of. An input port 7 and a discharge port 8 are provided at corresponding positions across the rotation center of the large diameter portion of this barrel 1,
They are opened and closed by lids 9 and 10, respectively, and a large number of stirring blades 11 are protruded from the inner circumferential surface of the barrel 1, and a discharge port is provided on the outer circumferential surface of the barrel 1. A vibrator 12 is attached near 8.

This mixing device has an input port 7 as shown in each figure.
The discharge port 8 is on the lower side when the angle is directed upward.
is closed by covering it with a lid 10, and two or more kinds of raw materials such as soil and soil, soil and sand, or soil and pigments with different colors are inputted from the input port 7, and the input port 7 is closed with the lid 9, and the motor 5 is closed. When the raw material is rotated by the stirring blade 1
While being stirred by 1, the mixture rolls within the barrel 1 and is mixed.

Here, the raw materials fed into the barrel 1 roll symmetrically around the large diameter part, so they are well-balanced and can rotate at high speeds, making it possible to mix them thoroughly in a short time, thereby destroying the mixed particles. After mixing is completed, when the lid 10 is removed with the discharge port 8 facing down, the inner periphery of the barrel 1 is sloped toward the discharge port 8, so that the water flows down smoothly and can be discharged quickly. However, at this time, if the vibrator 12 is started to vibrate the barrel 1, the frictional force between the raw material and the inner surface of the barrel 1 is reduced, and the discharge can be carried out more quickly. After the discharge of the raw material is completed, the discharge port 8 is covered with a lid 10, and the raw material can be inputted from the input port while keeping the barrel 1 in the same position. In addition, when changing raw materials, it is necessary to remove the raw materials that have adhered to the inside of the barrel, but in this case, if you wash the inside with water from the input port 7 with water, the adhered raw materials will be discharged together with water from the discharge port 8. This allows for extremely efficient cleaning. Note that by making the angle of the stirring blade 11 variable and adjusting it according to the type of raw material, the raw material can be processed most efficiently and the destruction of the mixed particles can be minimized.
