One end of the pull rod, which is close to the inlet, is fixed with the support frame through a nut, the other end of the pull rod is fixed on a baffle, and the baffle is fixed on a step of the inner cavity of the roller. The sum of the areas formed between the guide vanes is at least larger than the channel area of the inlet. The flow deflector and the flow guide frame can be manufactured into a whole or welded and assembled together. The support frame is welded with three claws, and the external circle size of the three claws is matched with the internal diameter of the filter cylinder.

The utility model discloses effect below having, this technical scheme increases on filterable basis has the whirl structure, carries out the water conservancy diversion to the high-pressure medium that presss from both sides miscellaneous impurity before passing through the filter core to centrifugal separation large granule avoids direct impact and collision filter screen, has prolonged the life of filter screen, and can effectively improve the filter effect.

Description of the drawings: 1. the device comprises a flange, 2, a sealing ring, 3, a support frame, 4, a rotational flow structure, 5, a filter element, 6, a filter cylinder, 7, a sewage collecting ring, 8, a blow-down valve, 9, an inlet, 10, an outlet, 11, a pull rod, 12, a baffle, 13, a flow deflector, 14, a flow guide frame, 15 and three claws.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

The utility model provides a high pressure filters whirl structure includes sealing ring 2, import 9, export 10, filter core 5, strains a section of thick bamboo 6, collection dirty ring 7, wherein import and strain a section of thick bamboo one end and pass through flange 1 and bolt fastening, and flange 1 with strain a section of thick bamboo contact department and seal with sealing ring 2, export 10 with strain a section of thick bamboo other end and pass through flange 1 and bolt fastening, the flow direction of medium is shown as the arrow in figure 1, strain and be equipped with filter core 5 in the section of thick bamboo, install whirl structure 4 at the front end of straining a section of thick bamboo, whirl structure can effectually avoid large granule impurity to get into the filter core, small pollutant is intercepted by the filter media when the filter core, and behind the structural water deflector filtering large granule of whirl, can wash according to operating condition often, can continue to use after.

The cyclone structure comprises a guide frame 14, guide vanes 13 and a pull rod 11, wherein the guide vanes 13 are arranged around the guide frame 14 in a clearance manner to form a disc shape, the center of the support frame is provided with the pull rod 11, the pull rod 11 is close to one end of an inlet and is fixed with the support frame 3 through a nut, the other end of the pull rod is fixed on a baffle 12, the baffle is fixed on a step of an inner cavity of a roller, the size of the outer circle of three claws of the support frame 3 is matched with the inner diameter of a filter cylinder 6 as shown in figure 4, the three claws 15 of the support frame 3 can be welded, a drain valve 8 is arranged on one side.

The distance between the guide vanes is based on the flow of the filtering system, the sum of the areas formed between the guide vanes is at least larger than the area of the channel of the inlet 9, and the number of the guide vanes is calculated.

As an alternative, the guide vane and the support frame may be made in one piece or welded together.

When the filter element is in operation, a working medium enters from the inlet 9, the flow direction of the working medium is changed after passing through the flow deflectors 13, the medium spirally flows in the filter cylinder, partial large particles mixed in the medium flow towards the dirt collecting ring 7 and the bottom area of the filter cylinder 6 under the action of centrifugal force, the large particles contact with the wall of the filter cylinder and are attached to the dirt collecting ring 7 and the bottom area of the filter cylinder 6, the large particles are deposited in the dirt collecting area by gravity when the system is shut down and are discharged through the blowoff valve 8, the blowoff valve is periodically opened according to the using condition of the system to discharge pollutants gathered at the bottom of the dirt collecting area out of the system, if the rotational flow structure needs to be cleaned, the nut is unscrewed after the filter cylinder is separated from the inlet through the flange, the pull rod on the support frame is removed, the nut is unscrewed, the support frame is taken out, each flow deflector.

In conclusion, the technical scheme is that the rotational flow structure is arranged at the front ends of the filter cylinder and the filter element, so that the problem that high-pressure media mixed with impurities directly impact and collide the filter element in the prior art is solved, and the service life of the filter element is prolonged.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected, and may communicate between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
