Abstract

PROBLEM TO BE SOLVED: To cut out fine particle raw material and to prevent the generation of a trouble of a scale system by providing a hitting hammer in a hopper and providing a striking bar for preventing the hanging of fine particle raw material by striking fine particle raw material in the hopper. SOLUTION: A hitting hammer 4 is attached on a side part of a lower part of a hopper 1 and a striking bar 5 is arranged having a predetermined length toward the inside from a side part of the hopper on the opposite side of the hitting hammer 4. This projection bar 1 can be moved up and down and driven in a predetermined amount. This strik bar 5 is arranged on an inside wall of a cone-like cylinder part 3 at an inclination angle of 60 to 80 from the inside to the outside. Thus, by combining the hitting hammer 4 and the up and down movement of the striking bar 5, trouble in the cutting out fine particle raw material can be settled, a supply amount to a screw feeder 2 is stabilized and no trouble of the scale system is generated.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hopper for storing and cutting out fine powder raw materials in the field of ceramics, etc. is there.

[0002]

2. Description of the Related Art Conventionally, a hopper for storing and cutting out fine powder raw materials has been widely used in the field of ceramics, and a knocker for giving a shock from the outside of the hopper is installed as a means for preventing the suspension of fine powder raw materials. However, depending on the type of fine powder, it has facilitated hanging.

Further, there is known a device for sending air into the hopper. However, depending on the type of powder, the air ejection port is clogged, resulting in malfunction.

Further, although it has been practiced to put the diaphragm inside the hopper, the residual powder adheres to the root of the supporting member of the diaphragm, resulting in malfunction.

[0005]

As described above, when the impact hammer is attached to the hopper that stores the fine powder raw material, the fine powder raw material is tightened and hanging up occurs, or a rat hole occurs and the raw material cannot be cut out. Therefore, a weighing system trouble occurs, automatic weighing becomes impossible, and fatal damage to the entire apparatus occurs. Therefore, a hopper that can stably cut out the fine powder raw material and does not cause a weighing system trouble has been desired.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and in order to solve the above problems, a hopper for storing and cutting out fine powder raw material is provided with a hammer for hammering. Another object of the present invention is to provide a shelving prevention hopper for fine powder raw materials, which is provided with a projecting rod for thrusting the fine powder raw materials in the hopper to prevent the fine powder raw materials from being suspended in the hopper.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The hopper for preventing fine powder raw material from being suspended according to the present invention is provided with a striking hammer in the hopper that stores and cuts the fine powder raw material, and hangs the fine powder raw material in the hopper by hanging the fine raw material in the hopper. It is characterized by the provision of a protruding rod to prevent this.

[0008] The hopper is a cylindrical one having a gradually lower cone and a pyramid shape which can be applied to refractory raw materials of fine powder and other fine powder. I am able to cut out each time.

A hitting hammer as in the prior art is attached to the lower side portion of the hopper, and a protruding rod having a predetermined length is provided on the opposite side from the side portion of the hopper toward the inside. The upper part of the stick is connected to an air cylinder or an electric cylinder so that the stick is moved up and down by a predetermined amount.

The projecting rod is arranged toward the center of the outlet of the hopper so as to push the fine powder raw material loaded in the hopper toward the outlet, and in combination with the above-mentioned hammer, the rathole of the fine powder raw material in the hopper is provided. The rack and rack suspension are broken, and the specified amount of raw material can always be taken out to the screw feeder to prevent troubles in the weighing system.

[0011]

1 to 3 show an embodiment of the present invention described above. As shown in FIGS. 1 and 2, the refractory hopper 1 made of a fine powder raw material is a cylindrical body having an upper portion with a diameter of 500 mm and a central portion with a diameter of 800 mm, and one side portion of the lower conical tubular portion 3 to which the screw feeder 2 is connected. Attach a hammer 4 to the opposite side, and on the opposite side, a projecting rod 5 with a diameter of 25 to 30 mm and a length of approximately 1700 mm.
Is projected from the inner side to the outer side on the inner wall of the conical tubular portion 3 at an inclination angle of 60 to 70 degrees.

The lower end of the protruding rod 5 is projected toward the center of the outlet 6 of the hopper 1, and an elevating / lowering drive device 7 for the air cylinder is connected to the upper portion thereof as shown in FIG. Further, it is driven up and down by 100 to 200 mm so as to operate in parallel with the hammer 4.

Lifting drive device 7 for the air cylinder
3 has a predetermined stroke as shown in FIG. 3, and is attached to the side surface of the hopper 1 by attaching the mounting portion 9 to the guide portion 8 of the thin cylinder connected to the lower portion. The upper part of the projecting rod 5 is inserted into and is connected to. 10
Is a protruding rod connecting portion.

When the refractory raw material loaded in the hopper 1 in this manner is cut out by the screw feeder 2, the impact hammer 4 is operated and the projecting rod 5 is driven up and down through the air cylinder, resulting in vibration and slippage. The raw material in the hopper 1 could be uniformly fed from the screw feeder 2 without generating ratholes and without hanging phenomenon, and no troubles occurred in the weighing system.

In particular, since the protruding rod 5 is arranged along the inner wall of the conical cylindrical portion 3 toward the outlet center, the raw material can be effectively and efficiently dropped to the outlet side. In addition, the raw material can be surely slipped off by setting the thrust rod to an angle of inclination of 60 to 70 degrees which is equal to or more than the angle of repose.

In the above description, the hopper for refractory has been described, but it is also applicable to cement, chemicals, grains and the like.

[0017]

As described above, according to the present invention, since the hammer and the ascent and descent of the hammer are used together, the trouble of cutting out the fine powder raw material can be solved and the supply amount to the screw feeder is stable. However, the weighing time was shortened without causing any trouble in the weighing system.

Further, the projecting rod is arranged toward the outlet of the hopper so that it can be driven to move up and down, or the projecting rod is set at 60.
By arranging so on the lower wall surface of the hopper at an inclination angle of ˜70 degrees, the fine powder raw material can be effectively and efficiently dropped to the outlet side.
