Embodiment 1

[0021] see figure 1 Example 1 will be described.

[0022] figure 1 is a drawing of a manufactured part employed in a filter element for processing food such as vegetable juice, fruit juice, etc. The groove 1 is formed at a desired position (in this embodiment, the outer surface of the cylindrical body 5 ) of the workpiece W (ie, the cylindrical body 5 ) having a thickness t and made of a single material. A plurality of continuous through holes 2 are drilled in the groove. Except for the groove 1, the rest 3 of the workpiece W has a strength maintaining function, and the workpiece as a whole is formed into an integral structure. Reference sign ф refers to the diameter of the outer surface of the cylindrical body 5 .

[0023] As a single material for the workpiece W, for example, drawn tubes made of various metals such as steel, stainless steel, and aluminum are used. A single material is machined, and the grooves 1 are formed on the outer surface of the cylindrical body 5 ...

Embodiment 2

[0027] Such as figure 2 As shown, the structure of Embodiment 2 is almost the same as that of Embodiment 1 except for the shape of the through hole 2 . Here, the tapered hole 8 is formed as the through hole 2 , whereas in Embodiment 1, the straight hole 7 is formed as the through hole 2 .

[0028] Such as figure 2 As shown in (d), when the liquid to be treated flows from Fi to Fo, the liquid passes through the tapered channel from the wide opening F1 to the narrow opening F2. The tapered hole formed on the bottom of the groove having a thickness t1 is composed of a tapered portion 8a and a straight portion 8b. The reference L2 refers to the length of the groove 1 . exist figure 2 In (d), the flow direction is shown from Fi to Fo, but the flow direction can be reversed.

[0029] The cross-sectional shape of the through hole is not limited to the shape of Embodiment 1 and Embodiment 2, and the cross-section can be formed into a desired shape, such as an arc.

Embodiment 3

[0032] Such as image 3 As shown, in Embodiment 3, the groove 10 is formed on the inner surface of the cylindrical body 5 , whereas in Embodiments 1 and 2, the groove 1 is formed on the outer surface of the cylindrical body 5 . exist image 3 , the through hole 2 is shown as a straight hole 7 , but the through hole may be formed as a tapered hole 8 .

[0033] The thickness of the bottom of the groove 10 is t2. The depth and length of the groove 10 are d2 and L3, respectively.

[0034] In a filter member employed in a filter for food processing or fluid treatment, slits may be formed on grooves instead of through holes.

Abstract

The invention provides a very sanitary perforated member with washable structure by the use of the single materials, such as metal, ceramics etc. The perforated member is especially suitable for the filter element and nozzle for processing food. The perforated member is provided with following advantages: reducing the steps of producing perforated member; reducing the accumulated location of external particle; having no need of additional reinforcing member; because of no need of welding step, reducing the possibility of strain, cracking, etc. Consequently, the high-precision and high-qualityperforated member can be obtained. The perforated member is formed by following ways: forming indented groove (1) on a desired position of work (W) made of single material; perforably mounting pluralthrough holes (2) in indented groove (1); and while the other parts (3) used as the strength retention part of work being formed into an integral structure except indented slot (2).

Description

technical field [0001] The present invention relates to filter elements for use as filter elements in solid-liquid, solid-solid, solid-gas separation devices and the like for handling various fluids such as gases or liquids. Background technique [0002] For example, existing such punching members are formed as follows. [0003] (1) In the case of manufacturing a three-dimensional filter element, generally, a flat plate is perforated as a first step, and then the perforated flat plate is formed into a three-dimensional filter element. Considering the machinability or accuracy of the perforated plate, the smaller the diameter of the holes to be drilled in the plate, the thinner the thickness of the plate. [0004] (2) An invention related to a multilayer composite filter element for series filtration has been disclosed (for example, Patent Document 1). The filter element has an inflow side and an outflow side for the inflow and outflow of the medium to be filtered. The fil...
