Description

[Detailed Description of the Invention] The present invention relates to a slit adjustment device in a closed-type continuous dispersion device.

In an apparatus in which a media such as sand or glass beads is introduced into a Vessel, a treatment liquid is fed therein, and the treatment liquid is continuously dispersed by a stirring disk that rotates at high speed. When a slit is formed between the body and a separating rotating body fixed to a rotating shaft, and when the media is separated by this slit and only the processing liquid is spouted, the interval between the slits is set according to the width of the liquid to be processed. It can be freely adjusted depending on the nature and type, or as necessary for cleaning the slit surface.

Examples of this type of configuration include, for example, Jikoaki
As shown in No. 49-36773, there is a known device in which an adjustment screw is attached to the outside of the rotating shaft, and the separation rotating body attached to the rotating shaft is moved up and down to adjust the spacing between the slits. .

However, such a configuration is only used when no special member is attached to the rotating shaft above the separating rotor that forms the slit, and this part is used to improve the discharge effect of the processing liquid flowing out from the slit. If the discharge vanes are fixed to the rotating shaft of the machine, the discharge vanes will get in the way, and the structure will become complicated, although it may not be impossible to adjust the spacing between the slits by moving the separating rotor up and down. , which is extremely difficult to manufacture.

In order to solve the above-mentioned problems, the present invention has developed a slit that allows the separation annular body to be screwed onto the lower part of the vessel head, and by adjusting the screwing depth, the fine spacing of the slits can be adjusted, and furthermore, the slit can be easily attached and detached. The present invention is intended to provide an adjustment device, and the present invention will be described below with reference to drawings of embodiments.

FIG. 1 shows the entire continuous dispersion device, 10 is a vessel, 11 is a vessel head, 12 is a discharge port provided in the head, 13 is a processing liquid pressure inlet, and 1 is a rotating shaft installed vertically in the vessel. The vessel head 11 is fixedly attached to the upper end of the vessel 10. The fixing means may be ordinary bolt tightening, but preferably a female recess is provided on one side and a male protrusion is provided on the other side for engagement.

The device of the present invention is installed at the bottom of such a vessel head, and as shown in the third figure, the rotating shaft insertion hole 14 provided in the vessel head 11 is inserted into the vessel head 11.
A stepped hole 15 with an enlarged diameter is formed on the inner circumferential surface of the lower end, and a guide ring 17 having a threaded groove on the inner circumferential surface and a plurality of bolt insertion holes 16 is fitted into the stepped hole 15. At 18, it is fastened to the Bethel head 11. Further, the separation annular body 7 has a threaded groove on its outer peripheral surface, and its inner peripheral surface has an inclined slit corresponding to the inclined slit surface 2a whose diameter gradually increases in the outflow direction of the separation rotary body 2 fixed to the rotating shaft 1. A surface 7a is provided, the threaded portion of which is screwed onto the guide ring 17, and a slit S is formed between the two slit surfaces. Further, the threaded portion of the separation annular body 7 is provided with a lock nut 1 having a threaded groove on the inner circumferential surface.
9 is screwed on.

In the figure, 20 is a stirring disk, 21 is a discharge blade, and 22 is a mechanical seal attached to the upper part of the vessel head 11.

Since the present invention has the above-mentioned configuration, the separation annular body 7 is screwed onto the two members, the guide ring 17 and the lock nut 19, so that it is securely fixed in a predetermined position and rotates even under the flow pressure of the processing liquid. without moving,
The distance between both slit surfaces 2a and 7a is kept constant. In addition, the processing liquid that is pumped is transferred to the separating annular body 7
The lock nut 1 does not fit into the threaded portion between the guide ring 17 and the lock nut 19.
9 can be loosened to smoothly rotate the separating annular body 7.
In addition to being able to freely adjust the spacing between a and 7a, both slit surfaces can be cleaned by taking it out.

Note that when the guide ring 17 is assembled, if the spacing between both slit surfaces is not uniform on the circumference,
The adjustment is made by loosening the bolt 18 and turning it.

As described above, according to the present invention, even if the discharge effect is enhanced by fixing the discharge blades to the rotating shaft above the separating rotary body constituting the slit, the separating annular body is screwed to the guide ring, and the separating annular body is Since the lock nut is screwed onto the body, the spacing between the slits can be freely adjusted by loosening the lock nut and turning the separating annular body to move it up and down. In addition, when the lock nut is tightened, it does not loosen even when subjected to the flow pressure of the processing liquid, so the predetermined slit interval is reliably maintained, and the threaded groove portion of the separation annular body is isolated from the processing liquid, so that the liquid does not loosen. Since it does not stick, it can be turned smoothly, and
Many effects are achieved, such as the ability to take out the separating annular body and clean the slit surface.
