All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1, 2, 3 and 4, the invention provides a rapid filter vessel, which comprises an upper split body 1 and a lower split body 2 which are hinged, wherein the upper split body 1 is provided with an inlet 3, the back side surface of the lower split body 2 is provided with an outlet group, an upper layer supporting mesh plate 4, a middle layer filter screen 5 and a lower layer supporting mesh 6 are sequentially arranged in the lower split body 2 from top to bottom, and the middle layer filter screen 5 is filter paper.

The upper-layer supporting mesh plate 4, the middle-layer filter screen 5 and the lower-layer supporting mesh 6 form a filtering system, filtering holes 14 are uniformly distributed on the upper-layer supporting mesh plate 4, one sides of the tops and the bottoms of the filtering holes 14 protrude out of the surface of the upper-layer supporting mesh plate 4 to form a semi-elliptical cover body 15, and the function of the semi-elliptical cover body is that when liquid to be filtered is poured, the impact of the gravity of the liquid directly acts on the upper-layer supporting mesh plate 4, so that the buffer for pouring the liquid is formed.

An annular frame 7 is arranged on the inner wall of the lower split body 2 opposite to the edge of the upper layer supporting mesh plate 4, the edge of the upper layer supporting mesh plate 4 is movably embedded into the annular frame 7, and a micro telescopic rod 8 connected with the edge of the upper layer supporting mesh plate 4 is arranged inside the annular frame 7.

When filtering to middle and later stages, work under miniature telescopic link 8 through the single chip microcomputer control that sets up in lower components of a whole that can function independently 2, the pulling suddenly, upper strata support mesh plate 4 stirs and waits to filter liquid and rotate, forms small whirl in waiting to filter liquid and flows, can make liquid be in one-way motion on the one hand, increases its potential energy, and on the other hand makes the quilt filter who piles up on the filter paper surface move, increases liquid filtration's effective pore area for liquid filters.

Further, because upper strata support mesh plate 4 is bamboo hat form, so can be when treating the liquid level of filtering liquid and constantly reduce, the action of moving liquid also reduces gradually, avoids being filtered the thing in the later stage and increases, and the amplitude of moving of upper strata support mesh plate 4 is too big, causes the fracture of filter paper.

And the upper strata that is bamboo hat form supports mesh plate 4 can be empting the liquid of treating to filter for liquid gathers to the centre that upper strata supported mesh plate 4, makes the quick disability of liquid.

Because the output end of the micro telescopic rod 8 is hinged with the edge of the upper layer supporting mesh plate 4, the upper layer supporting mesh plate 4 can rotate on the annular frame 7, and the annular frame 7 is connected with the inner wall of the lower split body 2 through the integral connecting ring 23.

According to the invention, the screen mesh 10 is used for dividing the middle layer screen 5 into a plurality of smaller unit screen bodies, the mesh shape of the screen mesh 10 can be circular, triangular or honeycomb, and the screen mesh simultaneously plays a role of reinforcing ribs.

The middle layer filter screen 5 divided by the screen mesh 10 forms a filter screen body of a smaller unit, which can disperse the gravitational potential energy of the whole liquid, but increases the gravitational potential energy on the filter screen body, thereby increasing the filtering efficiency of the filter paper on a unit area.

Further, the screen mesh 10 can be used as a reinforcing rib of the middle layer filter screen 5, so that the surface strength of the middle layer filter screen is improved, the structural strength of the middle layer filter screen in other forms of increasing the filtering efficiency by pressurization is improved, and the middle layer filter screen 5 is protected.

The bottom of the fixing ring 9 is arranged in a matching groove 12 formed in the inner side wall of the lower split body 2 through an annular spring 13, the annular spring 13 is arranged at the bottom of the integrated connecting ring 23, and the micro telescopic rod 8 is embedded into the integrated connecting ring 23.

The cover bodies 15 on the filter holes 14 on the left side and the right side of the surface of the upper-layer supporting mesh plate 4 are in mirror image relation.

A water locking groove 16 is formed at the joint of the annular frame 7 and the inner wall of the lower split body 2, and a sealing rubber jacket 17 matched with the water locking groove 16 is arranged on the upper split body 1 for improving the integral sealing performance in the mode of improving the filtering efficiency by pressurization.

The upper strata supports the mesh board 4 and the silk screen 10 all adopts the PET plastics, and lower floor's supporting network 6 adopts stainless steel metal material, and the aperture of the mesh of lower floor's supporting network 6 is far less than the aperture of the filtration pore 14 of upper strata supporting mesh board 4, and the purpose that sets up like this is in order to let liquid contact with upper strata supporting mesh board 4 fast to filter the complex mode through large aperture filter screen and small aperture, improve filter fineness.

As shown in fig. 5, a quick-coupling sleeve 18 is arranged on the upper split body 1 right opposite to the inlet port 3, a solenoid spring valve 19 is arranged inside the quick-coupling sleeve 18, the quick-coupling sleeve 18 is a quick-coupling in nature, the inlet port 3 is connected with an external liquid supply pipeline, and the inlet port 3 is closed and opened by controlling the solenoid spring valve 19.

Two pressure pipes 20 are provided on the back side of the lower split body 2, and the two pressure pipes 20 extend to the inner wall of the upper split body 1 and the sealing rubber jacket 17, respectively.

When the pressurization operation is performed through the pressurization pipe 20, there are two operation modes:

one, when getting into the filtration intracavity that the components of a whole that can function independently 1 and the 2 formation of lower components of a whole that can function independently treat when filtering liquid to a certain extent, electromagnetic spring valve 19 closes, stop the feed liquor, miniature air pump works under control panel 22's control, pressurization pipe 20 wants to filter the intracavity and carries out the pressurization of admitting air slowly, thereby improve filtration efficiency, when the pressure that adds 20 to exerting in the filtration intracavity reaches a certain extent, wherein be connected to the flap valve pipe 21 on the pipe shaft of the pressurization pipe 20 on the 1 inner wall of supreme components of a whole that can function independently, and then carry out the concora crush in the filtration chamber, avoid appearing the too big condition of pressure.

Secondly, when liquid to be filtered entering a filtering cavity formed by the upper split body 1 and the lower split body 2 reaches a certain degree, the electromagnetic spring valve 19 is not closed, the miniature air pump works under the control of the control panel 22, the pressurization is carried out on the rubber sealing jacket 17 connected with the miniature air pump through the pressurization pipe 20, the rubber sealing jacket 17 expands downwards, further force is applied to the integrated connecting ring 23, the integrated connecting ring 23 slightly displaces downwards, then the pressure is released reversely, the volume of the filtering cavity is temporarily increased in the downward pressurization process, the liquid entering the filtering cavity is increased, after the air inlet pressurization to the rubber sealing jacket 17 is stopped, the integrated connecting ring 23 slowly restores to the initial position under the restoring force of the annular spring 13, and at the moment, the pressurization is carried out in a mode of increasing the weight of the liquid to be filtered.

The micro air pump in the invention can be connected with the two pressurizing pipes 20 through a three-way valve, or the two independent micro air pumps can be used for independently controlling the two pressurizing pipes 20, and the air pressure and liquid gravity pressure ratio can be matched for pressurizing the filter screen through the two independently controlled pressurizing pipes 20, so that the pressurizing and filtering process is further optimized.
