Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a crusher for ceramic raw materials for ceramics and the like.

[Conventional technology]

The process of crushing pottery stone, feldspar, clay, etc., which are the raw materials for ceramics, is one of the important processes in the ceramic manufacturing process because the particle size of the raw materials has a great effect on the product.

As a crusher for these ceramic raw materials, a Joe crusher, an impact crusher, etc. are used as a coarse crusher, and a ball mill, a mill, etc. are used as a fine crusher.

The pulverizer to which this invention is applied is a mill-type pulverizer for fine pulverization used in relatively small-scale ceramic factories. Figure 4 shows an example of the structure of the main parts of a conventional pulverizer. show.

The crusher includes a stamp mechanism 1 having four stampers 1a, 1b, 1c and 1d, and four dies 4.
It consists of a mortar 4 having a, 4b, 4c and 4d. Each stamper 1a, 1b, 1c, 1d is
Stamp heads 11a, 11b, 11c,
11d, flanges 12a, 12b, 1 at the center.
2c and 12d, respectively, and are slidably attached to two upper and lower mounting frames 13 (however, only the lower mounting frame is shown) fixed to a frame (not shown). For these stampers 1a, 1b, 1c, 1d, cams 14a, 14b, 14c, 14d are attached to a rotating shaft 15, and rotation of the rotating shaft 15 causes each cam 14a, 14b, 14c, 14d to move to each stamper 1a, 1b. , 1c, 1d flanges 12
The structure is such that each stamper 1a, 1b, 1c, 1d reciprocates in the vertical direction by contacting the stampers 1a, 12b, 12c, and 12d. At this time, each cam 14
Since the cams a, 14b, 14c, and 14d are attached at different angles in the rotational direction of the rotating shaft 15, each cam 14a, 14b, 14c, and 14d
The timings at which the stampers abut against the respective flanges 12a, 12b, 12c, and 12d are different, and each stamper 1a, 1b, 1c, and 1d moves up and down with a time difference. Note that the rotating shaft 15 has gears 16, 17, a pulley 18, and a belt 1.
It is rotationally driven by a drive device (not shown) via 9. And stampers 1a, 1b, 1c, 1d
The raw materials in the dies 4a, 4b, 4c, and 4d are crushed by the vertical movement of the dies.

[The problem that the idea attempts to solve]

In the above-mentioned conventional crusher, mortars 4a, 4b,
The crushing operations in 4c and 4d are batch-type, and the supply of raw materials to each mortar and the removal of the raw materials after crushing are performed manually. In order to supply and take out this raw material, an operator will work near the crusher. The work of supplying and extracting raw materials is quite hard work, and in addition, the working environment is poor due to dust and noise, and the burden on the workers is heavy.

On the other hand, as a slag grinding device for recovering iron content from steel slag, one rim made of cast iron or cast metal is made from one edge of the other so that it can be successively transferred from bottle to bottle by grinding with a stamp rod. A closed stamp mill was developed in 1972-9602, in which several bottles with a gentle curvature were arranged in a row to be guided onto a conveyor, and had a supply regulating valve above the bottles.
It is disclosed in the publication No. This slag grinding device is a device that handles slag, which has a much larger particle size than the ceramic raw material that is the subject of this invention.
In the case of slag with a large particle size, it is thought that even in an apparatus with such a structure, the slag will sequentially flow downward from one bottle to the next in order due to its own weight. However, since the ceramic raw material is a fine powder, in an apparatus having such a structure, the ceramic raw material does not easily flow downward and accumulates in the middle, making it impossible to carry out a continuous crushing operation.

The purpose of the present invention is to automate and continuousize the supply, crushing, and removal of raw materials in the process of crushing ceramic raw materials, thereby reducing the burden on workers.

[Means to solve the problem]

In order to achieve the purpose, the ceramic raw material crusher of the present invention is a mill type ceramic raw material crusher equipped with a plurality of stampers and mortars. A conveyance path is provided, and a raw material supply gutter faces the mortar at one end, and a raw material discharge gutter is provided downstream of the mortar at the other end via a raw material conveyance path that communicates with the upper part of the mortar, and furthermore, The present invention is characterized in that a rotary blade for conveying the raw material, which is rotationally driven by a drive device, is provided on the conveyance path.

〔Example〕

Hereinafter, the features of the present invention will be specifically explained using examples with reference to the drawings.

FIG. 1 is a perspective view showing the main structure of a pulverizer according to an embodiment of the present invention, and FIG. 2 is a longitudinal sectional view of a mortar base of the pulverizer. In these figures, the same members as in FIG. 4 are given the same reference numerals and detailed explanations will be omitted.

As shown in FIG. 1, in this embodiment, grooves 21a, 21b, and 21c are provided between the dies 2a and 2b, between the dies 2b and 2c, and between the dies 2c and 2d provided on the mortar stand 2, respectively. At the same time, a groove 21d is provided on the exit side of the mortar 2d.

As shown in FIG. 2, the grooves 21a, 21b, 21c and 21d communicate with the upper parts of the dies 2a, 2b, 2c and 2d, and connect to the discharge gutter 22 on the exit side of the dies 2d.
It is formed so that it communicates with the

And each groove 21a, 21b, 21c and 21
Above d, rotary blades 23a, 23b, 23c and 23d, which are rotationally driven by an external drive device, are rotatably attached to a frame (not shown).

In the pulverizer with the above configuration, the raw material M is fed into the feed gutter 2.
4 is continuously supplied to the mortar 2a. The raw material in the mortar 2a rises upward while being crushed by the stamp head 11a, and overflows to the groove 21a side according to the amount of supply from the supply gutter 24 side. The raw material overflowing into the groove 21a is sent to the mortar 2b by the rotation of the rotating blade 23a. In the same manner, the raw materials are
The rotary blade 2 is crushed sequentially at c and 2d.
3d, it is discharged to the discharge gutter 22.

In this manner, the pulverizer of this embodiment can automatically and continuously perform the process from supplying the raw material to discharging the raw material.

Figure 3 shows an example in which a cover is attached to the mortar stand to prevent dust.

The cover 3 covers the periphery of the mortar stand 2 except for the input port of the raw material supply gutter 24, and prevents dust from the raw material being crushed from being scattered. Then, the chain 25 and the chain wheel 2 are attached to the side wall 31 of the cover 3.
6 is provided, and rotary vanes 23a, 23b, 23c, and 23d (see FIGS. 1 and 2) are rotationally driven by a motor 28 via a chain 27.

Although the above explanation has been given using the example of crushing raw materials for ceramics, the present invention can also be applied to crushing raw materials for ceramics such as refractories, cement, and glass, and the structure of the crusher itself is the same as that of the above embodiment. It goes without saying that the present invention is not limited to the structure shown in , and can be applied to a grinder having other structures as long as it is a grinder-type grinder having a plurality of dies.

[Effect of idea]

As explained above, in the ceramic raw material crusher of the present invention, in a mill type crusher having a plurality of stampers and mortars, the raw material supply gutter faces the mortar at one end, and the mortar at the other end faces the mill. A raw material discharge gutter is provided on the downstream side of the raw material discharge gutter, and a raw material conveyance path is provided between each mortar and between the mortar and the raw material discharge gutter on the other end side. A blade was provided to allow the material to be transported from one end to the other end and to the discharge gutter. As a result, the pulverizer of the present invention can automatically and continuously carry out the process from supplying the raw material to discharging the pulverized raw material, thereby significantly reducing the burden on the operator during the pulverizing operation. Furthermore, since there is no need to supply or take out raw materials for each mortar as in the past, a cover can be provided around the mortar to prevent dust from scattering and improve the working environment.
