Abstract

PURPOSE:To obtain an easy-to-install and -control valve by bringing a fixed disc having through holes corresponding to through-holes or U-shaped holes of a rotary disc into contact closely with the upper and lower sides of the rotary disc having the through-holes or U-shaped holes, and forming concentric grooves on one contact surface of each disc. CONSTITUTION:Fixed discs 1, 4 having through-holes corresponding to through- holes or U-shaped holes of a rotary disc is brought into contact closely with the upper and lower sides of the rotary disc 3 having the through-holes or U-shaped holes. Concentric grooves 6 for connecting the through holes of the disc 3, 4 are formed on at least one side surface of the contact surfaces of the fixed discs 1, 4 and the rotary disc 3. Therefore, simply by rotating the rotary disc 3, switching of a number of passages and the formation of circulation passages (U-shaped passages) are possible.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a pulp for switching flow paths in a continuous separation (for example, sugar solution separation) device.

[Conventional technology]

Conventionally, the route cutting means used in continuous separators can be roughly divided into means using a combination of electric valves and means using rotary pulp. The former has a fast switching speed and is easy to handle, and the material can be freely selected, but the control of the flow path, piping, and valves is complicated, and the dead volume tends to be large. The latter can cut many channels at the same time with one pulp and can reduce the dead volume including piping, but there are problems due to the sealing performance and cutting speed v1 due to its structure. Moreover, it is necessary to change the pump position when switching the flow path to conventional rotary pulp.

This must be programmed in advance.

[Problem that the invention seeks to solve]

The conventional flow path switching means described above has the problem of arrows.

(1) When using a combination of solenoid valves, the piping and valve control become complicated and the dead volume becomes large.

(2) The rotary pulp method requires advanced sealing technology, the switching speed is not necessarily fast, and it is necessary to change the entire pump flow rate when switching.

[Means for solving problems]

As a means for solving the above problems, the present invention provides a rotating disk having a required through hole or U-turn hole 1c in the @ direction and having an @ in the center, and a rotary disk having the same rotation on the side where the U-turn hole opens. A fixed disk having a through hole that is coaxial with the disk and communicates with the above-mentioned through hole or U-turn hole to cause fluid flow or U-turn by the required rotation of the co-rotating disk, and the contacting surface of the fixed disk. a fixed disk that is coaxially in close contact with the surface of the rotating disk on the opposite side and has a required through hole in the axial direction; and a fixed disk that is provided on at least one side of the surface in close contact between the fixed disk and the rotating disk. and the through hole of the rotating disk and 't-f
An object of the present invention is to provide a rotary valve characterized in that it is provided with concentric grooves that communicate with each other so that they can pass therethrough.

[Effect]

Since the present invention is constructed as described above, it has the following functions.

That is, by simply rotating the movable disk interposed between the fixed disks, one fixed disk is connected to the other fixed disk, and a large number of ridged channels can be switched and returned. U-turn path) can be formed.

〔Example〕

An embodiment of the present invention will be explained with reference to FIGS. 1 to 6.

In FIG. 1, a fixed disk 1 is in close contact with the upper surface of a movable disk 3, which will be described later. A plurality of nozzles 2, which are through holes, are drilled in the hole. The movable disk 3 has a shaft 11 at its center and is rotatable from being in close contact with the fixed disk 1 and the fixed disk 4 described below. On the upper surface of the fixed disk 1, as shown in Fig. 5 Φj, q, etc.
The fluid entering from nozzle 2 makes a U-turn and flows to another nozzle 2.
Axial hole 9 and radial communication hole 5 for reflux to
are provided in the shape of a letter 0, and apart from that, the connecting hole 5 and the bottom surface are defined by the hole 8, and eventually the top surface and the bottom surface are formed by the hole 8. This also includes the locations penetrated by 9.

These holes are provided so as to be connectable to required slots of a general example of a slow thread breaking device which will be described later with reference to FIGS. 7 and 8. The fixed disk 4 is coaxially and closely attached to the lower surface of the movable disk 3.

A plurality of holes 7 penetrating in the axial direction are formed. These holes 7
is a concentric circle @6 provided on the top surface as shown in Figure 3.
No matter what angle the movable disk 3 rotates, it is always connected to the hole 8 of the movable disk 3 so that the hole 8 passes through the hole 8 of the movable disk 3. As shown in Fig. 6, which shows a detail IIa of a close vertical cross-section of the fixed disk 1s, movable disk 3, and fixed disk 4, @6 is also half bored on the movable disk 3 side, and the mutual grooves are formed. The outer circumference of 6 is 0
It is sealed by a ring lO. Movable disc 3
The fIII hole 8 also communicates with this concentric groove 6, so that adults can always be transferred to and from the fixed disk 4 side. As shown in FIG.
4 is held and becomes a self-sealing nozzle, and the movable disk 3
It is configured to be able to send and receive fluid to and from the side hole 9 without leaking.

In addition, fixed date 1. The movable disk 3 and the fixed disk 4 are appropriately pressed in the axial direction by means not shown to prevent fluid from leaking between them, and the movable disk 3 is moved by a driving means not shown as required depending on the purpose. Rotate the angle of yc? .

Groove 6. Hole 8. Communication hole 5. Hole 9. The nozzle 2 is communicated with the fluid to pass in the r-axis direction, or the communication hole 5, the hole 9. It has a function of allowing only the tube 2 to communicate with each other to circulate the fluid.

Since this disaster example is configured as described above, holes 7 to 9. Communication hole 5. By appropriately selecting the number of holes, the radial pitch @6, and the radial distance 1 between the nozzles 2, the pitch (angle) in the circumferential direction, the hole 7 can communicate with the nozzle 2 at any position, or Once the communication between the nozzles 2 and the earth is established, and by connecting fluid pipes to each nozzle 2, switching of any number of channels or U-turns can be accomplished simply by rotating the movable disk 3. Rotary pulp is obtained.

Next, an example in which the rotary pulp of the above embodiment is applied to a continuous separation apparatus designated by reference numeral 101 and equipped with 12 adsorption/separation columns (t-columns) will be explained with reference to FIGS. 7 and 8. In this example, since there are 12 towers to be controlled, the nozzle 2 of the rotary pulp 101 has a hole of 24 m in advance as shown in FIG. There are also 24 pieces. Numbers 113 to 136 attached to each nozzle 2 in FIG. 2 are numbers corresponding to streams to be described later. Since there are six streams connected below the rotary pulp 101 as shown in FIG. 7, there are six holes 7 and correspondingly six concentric grooves 6 as shown in FIG. 3. . Therefore, the hole 8 of the movable disk 3 corresponding to the groove 6 is also 611! A is provided and communicates with the communication hole 5 corresponding to that position.

In addition, in hole 7, streams 137 to 142 6 in FIG.
In FIG. 7, where the book is connected, there are 24

The 2 finates are extracted from the stream 117, a predetermined amount is extracted from the stream 137, and the remainder flows into the stream 116 and circulates through each column 102 again. 133 streams lead to 141 streams n.

The circulation pump 108 supplies the entire stream of the pump 140 to 1
32 streams, each column 102t - circulates.

In this manner, the rotary pulp 101 controls all twelve columns 102 by directing streams 113-142 in eleven directions.
