The apparatus (high-pressure homogenizer) of Patent Document 1 has the following structure, as shown in FIG. 1 of Patent Document 1. A disc insertion hole (b) is drilled on the discharge side of the undiluted solution feed path (a) drilled in the cylinder block (1). The seat (2) and the disk holder (3) fitted therein are airtightly mounted to the cylinder block (1) from the outside of the disk holder (3) via the pressing body (4).

A force presses against the sheet (2).

Japanese Utility Model Laid-Open No. 52-143775

In the device of Patent Document 1 mentioned above, the disk (5) is fitted in the disk holder (3). A spring (7) is arranged inside the hold down body (4). In other words, the disk holder that accommodates the disk and the pressing body that accommodates the spring are separate members. Then, due to an assembly error between the disk holder and the pressing body, the central axis of the disk and the central axis of the spring may not coincide with each other, resulting in misalignment. If misalignment occurs, the direction of the force acting on the disk from the spring will not coincide with the central axis of the disk and will be biased, so there is a possibility that the disk will be tilted. If the device is operated with the disc tilted, the gap between the sheet and the disc becomes uneven in the circumferential direction, and the original performance is not exhibited, and the liquid is homogenized, emulsified, dispersed, or finely divided. may not be done sufficiently. In addition, there is a possibility that wear due to sliding between the disc and the disc holder and uneven wear of the disc due to non-uniform spacing between the sheet and the disc may occur, which may reduce the durability of the device. In addition, careful work is required to assemble the disk holder and the pressing body so as not to cause misalignment, which increases the number of man-hours for assembling the apparatus.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and its object is to provide a homogenizer that suppresses the occurrence of misalignment between the disc and the spring and improves durability and performance.

[Configuration 1]
The characteristic configuration of the homogenizer for achieving the above purpose is
It has a disc mechanism having a disc and a sheet arranged opposite to the disc, and a liquid is passed between the disc and the sheet to homogenize, emulsify, disperse, or atomize the liquid. a homogenizer that
The disk mechanism has a spring that presses the disk toward the seat, and a casing member that holds the disk and the spring,
The casing member is an integral member in which a disk accommodating portion in which the disk is arranged and a spring accommodating portion in which the spring is arranged are formed.

According to the above characteristic configuration, the casing member is an integral member in which the disk accommodating portion in which the disk is arranged and the spring accommodating portion in which the spring is arranged are formed. The axis is reliably aligned (centered). As a result, it is possible to realize a homogenizer with improved durability and performance by suppressing deterioration in performance and wear due to inclination of the disk.

[Configuration 2]
Another characteristic configuration of the homogenizer according to the present invention is
A second casing member, which is a casing member of the second disk mechanism, has a first disk mechanism and a second disk mechanism disposed downstream of the first disk mechanism. It is shorter than the length of the first casing member, which is the casing member of the mechanism.

When the second disk mechanism is provided on the downstream side of the first disk mechanism, the force acting on the disk in the second disk mechanism is smaller than that in the first disk mechanism, so the size of the second disk mechanism can be reduced. It becomes possible. Therefore, the length of the second casing member can be made shorter than the length of the first casing member, so that the homogenizer can be downsized and the manufacturing cost can be reduced.

[Configuration 3]
Another characteristic configuration of the homogenizer according to the present invention is
The casing member has a liquid inlet for inflow of liquid into the disk housing portion and a liquid outlet passage for liquid to flow out from the disk housing portion,
The liquid outflow path is inclined with respect to the central axis of the disk accommodating portion, and approaches the spring accommodating portion as the distance from the central axis of the disk accommodating portion increases.

According to the above characteristic configuration, the outlet of the liquid outflow path can be positioned relatively close to the spring accommodating portion, and the degree of freedom in layout of the device can be enhanced.

As shown in FIG. 4, an opening that communicates with the outside of the first casing member 11 is provided on the upper side of the first disk housing portion 11a. The opening corresponds to the first liquid outflow path 11f.

As shown in FIGS. 2 and 3, the first attachment portion 11g is a rectangular parallelepiped portion projecting from the first casing member 11 in the front-rear direction. The fixture X attaches the first disk mechanism 10 to the liquid supply section 4 via the first attachment portion 11g.

The first seat 12 (an example of a seat) is a cylindrical member, and is housed in the first disk housing portion 11a in a posture in which its central axis coincides with the central axis 11b of the first disk housing portion 11a. there is In this embodiment, the right side surface of the first sheet 12 (the surface facing the first disk 13) is formed flat.

The upper, lower, front, and rear sides of the first disk housing portion 11a are formed flat in conformity with the shape of the outer peripheral surface of the first disk 13a. The first disk containing portion 11 a is formed so that its inner diameter is slightly larger than that of the first disk 13 . In this embodiment, the left side surface of the first disk 13 (the surface facing the first sheet 12) is formed flat.

The first impact ring 14 is a cylindrical member, and is housed in the first disk housing portion 11a with its central axis aligned with the central axis 11b of the first disk housing portion 11a. A first impact ring 14 is arranged outside the first seat 12 and the first disc 13 . The liquid Z that has passed through the gap between the first sheet 12 and the first disc 13 collides with the inner surface of the first impact ring 14 .
