The embodiment is as follows:
referring to fig. 1, a pressure vessel 1 having a built-in two-stage serial filtration device in a preferred embodiment of the present invention is a tank-shaped structure, a feed inlet 103 and a discharge outlet 104 are correspondingly formed on the pressure vessel 1, and a primary filtration mechanism 2 and a secondary filtration mechanism 3 are sequentially disposed on a fluid transmission path between the feed inlet 103 and the discharge outlet 104, so that a mixed fluid can enter the pressure vessel 1 from the feed inlet 103, and after sequentially passing through the primary filtration mechanism 2 and the secondary filtration mechanism 3, a solid medium and a liquid medium are filtered out, and a gas medium is sent out from the discharge outlet 104.
It can be understood that, in actual arrangement, the arrangement positions of the inlet 103 and the outlet 104 may be correspondingly arranged according to requirements, for example, the form of the inlet 103 on the top of the housing and the outlet 104 on the bottom of the housing shown in fig. 1; obviously, the arrangement positions of the feed inlet 103 and the discharge outlet 104 can be correspondingly changed according to requirements, or one or two of the feed inlet and the discharge outlet can be arranged on the side wall surface of the shell. Regardless of the arrangement, so long as both filter mechanisms are capable of accomplishing filtration of the fluid media as shown in the preferred embodiment. As follows, a specific example of the case shown in fig. 1 will be described.
Specifically, the primary filtering mechanism 2 and the secondary filtering mechanism 3 in the preferred embodiment have different filtering directions, and more specifically, the filtering direction of the primary filtering mechanism 2 is the same as the feeding direction of the fluid in the pressure vessel 1, so that the fluid can quickly complete primary filtering after entering the vessel, and the direction of the primary filtering is further preferably vertical, so that the solid medium in the mixed fluid can be quickly settled and adsorbed under the action of gravity; accordingly, the filtering direction of the secondary filtering means 3 is preferably at an angle with the vertical direction, for example, at an angle of 90 ° with respect to each other as shown in fig. 1, that is, the fluid (mainly the gas therein) passing through the primary filtering means needs to be deflected by 90 ° before being filtered and outputted from the secondary filtering means 3.
By the arrangement, the characteristics of high density of the liquid medium, high movement inertia, difficulty in changing speed direction, low density of the gas medium, low movement inertia and easiness in changing speed direction can be effectively utilized, liquid and gas present different movement tracks as shown in figure 6, and the liquid medium and the gas medium in the mixed fluid are quickly separated. Thereafter, the gas medium subjected to the secondary filtration by the secondary filtration mechanism 3 is discharged through the discharge port 104.
It will be appreciated that the direction of the secondary filtration may be at other angles to the direction of the primary filtration than the above arrangement at 90 to each other, for example at an acute angle of less than 90 or at an obtuse angle of more than 90. Taking the form in fig. 1 as an example, in this case, the primary filtering direction is vertical, and the filtering surface of the secondary filtering mechanism 3 extends vertically; and when the secondary filtering direction and the primary filtering direction form other angles, the filtering surface of the secondary filtering mechanism 3 extends along the oblique direction.
More specifically, the primary filter mechanism 2 in the preferred embodiment, as shown in fig. 2 to fig. 4, includes a baffle framework 203, the baffle framework 203 is fixedly or detachably connected in the pressure vessel 1, and divides the casing space into an upper part and a lower part (i.e. the baffle framework 203 is connected with the inner wall surface of the casing in a sealing way), and a filter unit 202 is arranged on one side of the baffle framework 203 close to the feed inlet 103, and a communication hole 2032 is arranged on the baffle framework 203 corresponding to the filter unit 202 for the medium penetrating through the filter unit 202 to pass through, thereby completing the primary filtration.
In practical implementation, the baffle framework 203 in the preferred embodiment is a plate-shaped structure, and a plurality of accommodating grooves 2031, for example, 7 ones shown in fig. 3, are formed on the top surface of the baffle framework. The receiving groove 2031 in the preferred embodiment is preferably circular, and is used for receiving the circular filter unit 202 in an embedded manner. Correspondingly, in order to realize reliable setting of the filter unit 202, the cover plate 201 is arranged at the top of the baffle framework 203, the size of the cover plate is not larger than that of the baffle framework 203, through holes with inner diameters slightly smaller than that of the accommodating grooves 2031 are respectively formed in the plate body corresponding to the accommodating grooves 2031, and therefore the circumferential direction of each filter unit 202 is guaranteed to be pressed and held by the cover plate 201 while the work of the filter unit 202 is not influenced.
Further, the secondary filter mechanism 3 in the preferred embodiment includes a filter cartridge 301 having a cylindrical structure as shown in fig. 5, in order to prevent the liquid medium after the secondary filtration from flowing out through the filter cartridge 301, the filter cartridge 301 in the preferred embodiment is disposed at a position higher than the bottom of the vessel shell, and is further preferably disposed on a support pipe 303, one end of the support pipe 303 is sleeved with the bottom end of the filter cartridge 301, and the other end is connected to the discharge port 104 as shown in fig. 1. In order to facilitate the sleeving between the support tube 303 and the filter cartridge 301, an annular step is preferably arranged at the top of the filter cartridge 301, so that the bottom of the filter cartridge 301 is just inserted into the annular step to complete the sleeving; accordingly, the other end of support tube 303 is preferably threadably mated with spout 104.
It can be understood that the supporting tube 303 is disposed inside the pressure vessel 1, a through hole is formed in the middle of the supporting tube 303 to communicate the filter cartridge 301 with the discharge port 104, and the discharge port 104 is downward when the pressure vessel 1 is in use, so that it is ensured that the liquid medium separated by the secondary filtration can be reliably stored at the bottom of the pressure vessel 1, as shown in fig. 7.
In more detail, the end of the filter cartridge 301 facing away from the support tube 303 is preferably closed by a top plate 302, so that the gaseous medium can only pass through the filter cartridge 301 of the secondary filter mechanism 3 before it can be discharged via the outlet 104. Meanwhile, in the preferred embodiment, the filter cartridge 301 is preferably a cylindrical structure, but it is obvious that the filter cartridge 301 may be configured as a square cylinder structure, a (forward/backward) cone cylinder structure, or the like, to meet application requirements in different application environments. In addition, in a preferred embodiment, the filter cartridge 301 is further preferably formed by sintering after layering a multi-stage metal mesh, and the layering sequence of the metal mesh is gradually improved from outside to inside in precision, so that the gas medium is ensured to flow from the outer cylinder to the inner cylinder; for example, in one embodiment, the wire mesh sintered filter cartridge 301 is sintered and formed by 7 layers of wire mesh that are layered with a precision that is gradually increased from 30 μm to 10 μm.
In the preferred embodiment, the filtering precision of the primary filtering mechanism 2 is preferably 30-50 μm, and the dust holding capacity is set to be 70-80% of the total dust holding capacity of the pressure vessel 1; the filtering precision of the secondary filtering mechanism 3 is preferably 10-15 μm, the dust holding capacity is set to be 20-30% of the total dust holding capacity of the pressure vessel 1, and the effective filtering area of the filter cartridge 301 is preferably 20-40% of the total effective filtering area of all the filtering units 202 on the primary filtering mechanism 2.
In one embodiment, the filtering unit 202 in the preferred embodiment is a laminated metal filtering net, which is a round cake structure formed by pressing a metal wire net through a mold, and is further preferably pressed into the accommodating groove 2031 in an interference fit manner, wherein the interference is 0.05mm to 0.1mm.

The height is 48mm, the thickness is 2mm, and the filtering area is 6635mm 2 The dust collector occupies 24.6 percent of the filtering area of the first-stage filtering mechanism 2, the filtering precision is 10 mu m, the dust containing amount is 150g, and the dust collector occupies 21.2 percent of the total dust containing amount. Furthermore, the height of the support tube 303 from the outlet 104 of the pressure vessel 1 is 80mm, and the maximum volume of the separation liquid contained in the closed space formed by the lower edge of the metal wire mesh sintered filter cylinder 301 and the outlet end socket of the pressure vessel is 1.45mL.
