Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a crusher of a type in which a crushed material is stirred with a crushing medium in a crushing tank and crushed.

[Conventional technology]

A crusher that arranges a shaft in the center, attaches a number of agitator arms and axial pump blades to the shaft, puts crushing media in a crush tank, rotates the agitator arm while circulating crush, and agitates and crushes Are known.

[Problems to be solved by the device]

However, in this conventional crusher, the crushed material fed into the crushing tank rises in temperature due to the heat generated when it is crushed by the rotating agitator arm and the crushing media, so it is necessary to cool the processing tank. For this reason, a jacket must be attached to the processing tank, and there is a drawback that the cost becomes high because it is necessary to use a dedicated tank.

In view of the above-mentioned problems of the prior art,
It is an object of the present invention to solve this problem, and to provide a crusher having a simplified structure that suppresses heat generated during crushing, efficiently obtains high-quality products, and is robust.

[Means for solving the problem]

As a means for achieving this, the present invention provides a vertical grinding tank with a jacket, and a water pipe for passing water through the jacket is attached to the jacket, and the upper end of the water pipe is connected to a vertically movable and swivelable frame. The crushing tank is held in the crushing tank, and the crushing media are accommodated in the space formed by partitions such as screens provided in the upper and lower parts of the crushing tank. An axial pump blade is attached to the lower end of the stirring shaft.

〔Example〕

An embodiment of the structure of the present invention shown in the drawings will be described in detail below.

A cooling jacket 2 is attached to the outer periphery of the vertical cylindrical grinding tank 1. A water pipe 3 for passing cooling water is attached to the cooling jacket 2, and the upper end of the water pipe 3 is attached to a frame 14 located above and connected to an external water pipe. By attaching the water pipe 3 to the frame 14, the crush tank 1 is held under the frame 14 in a suspended state.

On the other hand, a partition consisting of a screen 4 is stretched in the lower part inside the crushing tank 1, and a ring-shaped fixed plate 5 is attached in the upper part, and the stirring plate which will be described later is separated from the fixed plate 5 with a gap e. By forming the partition 7 by facing the rotary plate 6 attached to the shaft 10, a space 8 is formed between the screen 6 and the partition 7.

An agitator arm 11 in which a large number of grinding media 9 are housed in the space 8 and a stirring shaft 10 rotatably mounted on a frame 14 is vertically penetrated and the stirring shaft 10 is mounted in a plurality of stages To arrange.

Also, the stirring shaft protruding below the screen 4
An axial flow vane 12 is attached to the lower end of 10 to form an axial flow pump that rectifies the liquid flow with the guide vanes 13 provided on the crushing tank 1 side and sends it into the crushing tank 1.

The frame 14 has a hydraulic section 15 with a built-in hydraulic cylinder.
It is mounted so that it can be moved up and down by a piston 16 projecting upward from and is pivotable. Further, a motor 17 is vertically attached to one end of the frame 14, and a belt 20 is stretched between a pulley 18 attached to the upper end of the motor 17 and a pulley 19 attached to the upper end of the stirring shaft 10. The stirring shaft 10 is rotationally driven by the motor 17.

Reference numeral 21 is a movable type processing tank having wheels 22 attached to the lower end.

Since it is configured like this, to operate this,
First, the hydraulic unit 15 is operated to raise the piston 16, and the frame 14 and the crushing tank 1 attached to the piston 16 are raised, and then the processing tank 21 containing the processed material is moved and arranged below the crushing tank 1. The hydraulic part 15 is operated again to lower the crushing tank 1, and the lower part is immersed in the processing tank 21.
Then, when the motor 17 is turned on, the pulley 18,
The stirring shaft 10 is rotated via the belt 20 and the pulley 19. When this stirring shaft 10 rotates, the axial flow blades
12 and the agitator arm 11 also rotate, and the axial flow blades 12 suck up the processing in the processing tank 21, but the sucked processed material ascends while passing through the crushing tank 1 in the agitator arm.
It is stirred together with the crushing medium 9 by 11, and is crushed and dispersed by the crushing action and overflows from the gap e in the upper part. This operation is repeated for many times by operating for a predetermined time, so that a pulverized dispersion having a desired particle size can be obtained. During this operation, cooling water is supplied and circulated from the water pipe 3 to the cooling jacket 2 on the outer periphery of the crushing tank 1 to cool the crushing tank 1, so that the agitator arm 11 and the crushing media 9 generate the stirring and crushing action. The heat is cooled so that the temperature in the crushing tank 1 can be maintained at a temperature suitable for the processed material, and the temperature of the processing tank 21 tends to rise due to the processed material circulating by the crushing action. The inside of the processing tank 21 is maintained at an appropriate temperature by the surface, and the pulverized pulverized dispersion can obtain a pulverized product of uniform quality.

Further, in this crushing action, the stirring force and pump-up ability can be controlled by arbitrarily changing the distance between the bottoms of the crushing tank 1 and the processing tank 21, and it is possible to respond to changes in the viscosity of the processed material. You can

[Effect of device]

As described above, in detail, the present invention,
A cooling jacket is provided on the outer circumference of the crushing tank so that it can be immersed in the processing tank. It is possible to efficiently absorb, maintain a suitable temperature, and efficiently obtain a uniform and high-quality pulverized product.
In addition, since the water pipe for passing water to the cooling jacket is also used as a holding means for vertically suspending the grinding tank,
This has effects such that a complicated means for attaching another member can be omitted and the structure can be simplified. Also, since the grinding tank is connected to a frame that can be moved up and down and swung,
The stirring power and pump-up capacity can be controlled, and it is possible to respond to changes in the viscosity of the processed product.
