Description

[Detailed Description of the Invention] The present invention relates to a porcelain rod for pulverization that is housed in a pulverizer such as a rod mill.

Conventionally, pulverization of granules and the like has been carried out in a fine pulverizer such as a rod mill that accommodates steel balls and steel rods, but rod-shaped pulverizers have been preferred because they can be pulverized quickly and with low noise.

However, steel bars have the drawback of adversely affecting the crushed material, such as chemical changes, and the applicant of the present application
No. 6181), they provided a porcelain one to eliminate this drawback.

This porcelain rod is also extremely effective, but due to the nature of its material,
It was difficult to manufacture long lengths, and there was also the problem that lengths that matched the size of the mill had to be manufactured each time.

The present invention has solved this problem, and the illustrated embodiments of the present invention will be described below.

In this example shown in Figures 1 and 2, 1 and 2 are short connecting rods made of hard porcelain such as alumina porcelain, and 3 is a long connecting rod also made of hard porcelain, which is inserted into the center of each. Hole 1
a, 2a, and 3a are transparent in the horizontal direction.

A fitting protrusion 1b is provided at one end of the connecting rods 1 and 3. 3b is provided protrudingly, and fitting protrusions 1b, 3b are provided at the other ends of the connecting rods 2, 3.
Fitting recesses 2b and 3C that can be fitted are formed.

Further, accommodation holes IC and 2C are opened at the other end of the connection rod 1 and one end of the connection rod 2 and communicate with the insertion holes 1a and 2a.

Reference numeral 4 designates a bolt-shaped connecting rod made of stainless steel, with a stopper 4a fixed to one end thereof and a screw 4b carved into the other end.

5 is a nut screwed onto the screw 4b.

Then, the short connecting rod 1, an appropriate number (three in the figure) of long connecting rods 3, and the short connecting rods 2 are inserted into the insertion hole 1a in this order.
, 2 a , 3 a , insert the connecting rod 4 (see Figure 3)
, the stopper 4a is housed in the housing hole 1C of the connecting rod 1, and the nut 5 is screwed onto the screw 4b of the connecting rod 4 protruding from the housing hole 2C of the connecting rod 2 at the other end to house the nut 5. It is accommodated and arranged in the hole 2C.

This connects the connecting rods 1, 2.3 and connects the long porcelain rod S.
can be formed.

The openings of the receiving holes 1c and 2c are filled with a filling material 6 such as white cement or a liquid resin that hardens by baking or the like.

Also, apply the connecting agent 7 to the connecting rod 4 and connect the connecting rods 1, 2.3.
The insertion holes 1a, 2a, and 3a are tightly connected with the connecting agent 7 by inserting the connector into the connector.

However, it is not necessary to close the insertion holes 1a, 2a, and 3a.

Since this example is constructed in this way, a long porcelain bar S can be formed depending on the number of connected connecting rods 3, and since each connecting rod can be manufactured uniformly, a straight porcelain rod S can be formed.

In addition, there are several types of connecting rods with various lengths (for example, 5Q
mm, 3Qmm, 10 mm), you can easily obtain a porcelain bar with a length that corresponds to the size of the mill, as shown in Figure 4.

In addition, when using it, it is housed in a mill K as shown in FIG. 5, and the porcelain rod S is rotated by the rotation of the mill to crush the powder.

Although this example is configured as described above, the present invention is not limited to this.

For example, the shape of the connecting rod and the shapes of its both end surfaces are not limited, and may simply have an insertion hole formed therein.

In this case, as shown in FIG. 6, the stopper 8a of the connecting rod 8 protruding from both ends and the nut 9 of the engagement material screwed onto the threaded portion may be covered with a porcelain covering 10 and fixed with adhesive. good.

At this time, the gap A is filled with a filler such as adhesive or white cement, or the connecting rod 11 is used to fix the arrangement of the covering 10.
An engagement groove 11a may be formed at one end of the cover 10, into which the covering 10 is fitted.

Further, the material of the connecting rod is not limited, and it may be made of hard plastic, light metal, etc., and the connecting rod may be formed into a pipe shape.

Furthermore, the material and shape of the stopper provided at one end of the connecting rod may be suitably selected. For example, as shown in FIG.
2, or as shown in FIG. 8, it may be a stopper 13 made of porcelain or the like that fits with the connecting rod 14, or it may simply be a long bolt.

Note that the configuration of the locking portion formed at the other end of the connecting rod is arbitrary, and in addition to the threaded portion, a locking portion 15 of a locking protrusion may be provided protrudingly as shown in FIG. 9.

In this case, the engagement material may be covered with an engagement material 16 made of hard rubber.

Therefore, the shape and material of the engaging member are also appropriate depending on the configuration of the locking portion of the connecting rod.

In short, the present invention consists of a plurality of connecting rods made of porcelain such as alumina porcelain and each having an insertion hole through the center, and a connection having a locking part such as a screw formed at one end and a stopper protruding from the other end. a rod, and an engaging member that engages with the locking portion;
A pulverizer that can be made into an appropriate length by inserting the connecting rod into the insertion hole of each connecting rod and engaging and fixing the locking part with an engaging material to connect a plurality of connecting rods. This is a porcelain rod used for crushing.

Therefore, according to the present invention, a long porcelain bar can be easily formed by connecting the connecting rods, and the length can be changed by connecting the connecting rods by the number of connecting rods or by connecting connecting rods of different lengths, so that the size of the mill can be adjusted. It has the great effect of being able to adjust the length, and since it is made of porcelain, it has the advantage of being low noise and not causing any chemical changes to the crushed material.
