Description of the Invention: [Technical Field] The present invention relates to an inertial over-rule, which is obtained by passing a gas stream or the like through a through-hole filled with an incompressible fiber The non-compressible fibers collide with particles in the gas stream to fractionally capture the particles. [Prior Art] A conventional inertial filter 1A will be described with reference to Figs. 15A and 15B. The conventional inertia over 1 1GG system is disposed in the air flow passage and can perform particle classification, and has a cylindrical transition body 1〇1. The filter body 丨〇1 has a circular through-hole 102 through which the airflow passes through the upstream side downward (four) direction. The through hole 102 includes a reduced diameter through hole 1〇2a whose inner diameter gradually decreases from the upstream side toward the downstream side by the airflow, and a fixed diameter through hole which is fixed to the inner diameter of the reduced diameter through hole 102a on the downstream side. . The sizing through hole 102b is filled with a metal fiber 103 as an example of an incompressible fiber. The metal fiber 1〇3 prevents the self-diameter through hole 102b from falling downward in the axial direction by a mechanism (not shown). In the inertia filter 100, after the internal pressure of the inertial filter 100 is lowered to the external pressure or less by the suction force of the pump (not shown), the pressure difference generated between the two pressures is applied to the through hole 102. The middle arrow A generates a gas flow in the direction B. Thus, the particles can be classified. The air velocity rises in the reduced diameter through hole 102a, and becomes intrinsic after flowing into the fixed diameter through hole 1 〇 2b. Further, in the sizing through hole 102b, the fine particles contained in the airflow collide with the metal fiber 103 to be captured (captured). Patent Document 1: Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. 2011-27473. In the inertial filter 1A shown in FIG. 15A, if the velocity of the airflow rises, the metal fiber 1〇3 is received by the airflow. The axial direction pressure is compressed downward in the axial direction as shown in Fig. 15B. However, the above compression is not exaggerated, and compression other than this form is also included. Hereinafter, it demonstrates in more detail. First, the inner diameter of the reduced diameter through hole 102a of the inertia filter 1a becomes smaller toward the downstream side of the airflow, so that the airflow is gradually accelerated, and then passes through the sizing through hole 1 at a constant speed to capture the particles at the time of passage. The sizing through hole 102b is a filter structure in which the metal fiber 1〇3 is layered. g) This can apply the Stokes Number stk and the Becker number which can be used for the gas flow rate and the fiber diameter.

The proportional ratio is proportional to the square of the particle size and is inversely proportional to the fiber diameter. According to the Stokes number Stk formula, as the flow velocity of the gas becomes larger, the suspended particles from the larger particle size cannot follow the movement of the gas in sequence, and escape from the gas flow path and collide with the gold I fiber 1G3. The particle diameter is controlled by selecting the flow rate of the gas and selecting the fiber diameter, thereby selecting the particle diameter of the particle of the capture target. In the conventional inertial filter 1〇〇, the fiber diameter of the metal fiber (8) is extremely small, so that it is not necessary to increase the flow velocity of the gas flow to the extent of the impactor, and the metal fiber 103 can not only capture particles by the inertia of the particles, Particles can also be captured by capture, gravity, electrostatic forces, diffusion, and the like. 4 201127473 The Becker number Pe series table* is the ratio of the effect of transporting particles by airflow to the effect of spreading particles, which is proportional to the flow rate and fiber diameter and inversely proportional to the diffusion coefficient. In order to reduce the impact of diffusion, it is necessary to increase the Becker number pe. It can be seen that the smaller the particle diameter, the larger the diffusion coefficient, and the smaller the fiber diameter system is selected. Therefore, increasing the flow rate is preferable for improving the selectivity of the particle diameter. According to the above, the target particles can be captured or classified by the metal fibers by selecting the flow velocity, the fiber diameter, and the like. Further, in the conventional inertial filter 1 豆, the filling amount of the metal fiber 1G3 in the sizing through hole is adjusted to adjust the void ratio and the fiber diameter of the metal fiber 1G3, so that the sizing through hole is not made. The airflow in the lion is greatly reduced, and the pressure loss is suppressed to a small level. Even if a small airflow is used to attract vegetables for small flow attraction, the particle inertia effect required to remove the particles can be obtained. Therefore, when the inertia filter 100 is compressed downward in the axial direction and the distance between the metal fibers 103 is reduced as shown in FIG. 5B, the void ratio changes greatly, and the pressure loss increases. The capture efficiency does not fall as desired. SUMMARY OF THE INVENTION An object of the present invention is to provide an inertial filter which can stably perform particle grading even if a metal fiber having a diameter of 1 is penetrated from a gas flow, and the trapping efficiency does not decrease for a long period of time. The inertia filter of the present invention includes a filter body having a through hole in an axial direction and an incompressible fiber filled in a through hole in the axial direction; and a holding mechanism for resisting passage of the fluid through the through-shrinking fiber Axial direction compression force, #细力 and this in the axial direction of multiple parts to protect 201127473 s 玄玄非压缩性镳 fibers, the above fluid is not limited to gases, including liquid other fluids. The particles captured or captured in the inertial filter are not limited to & particles suspended in a gas, and include particles suspended in other, agents such as liquids or other solvents. The above non-compressible fiber is preferably made of a metal fiber. Further, as the metal fiber, for example, a stainless steel fiber is preferable, but it is not limited to the non-recorded steel fiber, and may be a metal fiber selected from the group consisting of aluminum fiber, copper fiber, and other metal fiber. Further, if the non-compressible fiber is incompressible and there is almost no volume change of the fiber to the metal fiber even if the south-speed gas stream passes. Feeding

The upper side is passed as an air flow through the upstream side, and the air flow is from the arrow. : Flow in, and pass the lower side as the airflow through the downstream side, and the airflow is directed toward the arrow ι. This airflow is generated by suction of the airflow (not shown) disposed on the downstream side of the airflow, and the airflow in the through hole 3. The through-hole 8 201127473 3 is a reduced-diameter perforation 3a whose inner diameter is gradually reduced from the upstream side toward the downstream side by the airflow, and the airflow connected to the reduced-diameter through-hole 3a passes through the downstream side: also the fixed-diameter through-hole 3b constitutes a through-body through The hole 3b is 'filled with the metal fiber 4 as an incompressible fiber which changes almost in volume even if a high-speed airflow passes. The metal fiber 4 is preferably a SUS (stainless steel) fiber, but is not limited to the SUS fiber, and may be a metal fiber selected from the group consisting of aluminum fiber and copper fiber 'other metal..', if it is non-compressive. In the above configuration, the first embodiment includes the holding mechanism 5, and the holding mechanism 5 acts against the airflow through the sizing through hole 3b, even if the fiber having almost no volume change is passed through the high-speed airflow.

The holding mechanism 5 includes a filter case 5a inserted into the fixed diameter through hole 3b from the axial direction, and a plurality of axes in the axial direction. Each of the portions is locked to the plurality of lead beams 5b of the filter case 5a in a state in which the filter case 5a is penetrated in the radial direction. The lead beam 5b is inserted into the filter case 5a and filled with the metal fibers 4, and passes through the filter case 5a. In the penetrating state, the metal fibers 4 in the through-holes 3b can be held in a plurality of portions in the axial direction. The production of the holding mechanism 5 will be described with reference to Figs. 2 to 5C. The appearance of the filter case 5a in the filter 1 is shown in Fig. 3, which shows the cross-sectional configuration of the transition phase 5a of Fig. 2, and Fig. 4 shows the cross-sectional configuration of the filter case 5a in the state in which the metal fibers 4 are not accommodated, Fig. 5A 5B and 5c show the state in which the lead beam 5b is inserted and mounted in the filter case 5a of Fig. 4. 201127473 As shown in Fig. 2 and Fig. 3, the "filter box 5" is a cylindrical case, as shown in Fig. 2 4 is shown in the transition box 53 filled with metal fibers 4.
