Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work all belong to the protection scope of the present invention.

Referring to fig. 1, a dry cartridge filter 100 is used to filter and dry a liquid or gas.

The drying filter cartridge 100 comprises a cartridge body 1, a flange assembly 2, a head 3 and VCR joints 4, wherein the cartridge body 1 forms a feed end and a discharge end respectively at both ends along the length direction, the flange assembly 2 is detachably connected at the feed end of the cartridge body 1, one VCR joint 4 penetrates through the flange assembly 2 and is communicated with the inside of the cartridge body 1, the head 3 is formed at the discharge end of the cartridge body 1, and the other VCR joint 4 is connected on the head 3 and is communicated with the inside of the cartridge body 1.

The feeding end of the cylinder body 1 forms an annular mounting table surface, and the flange component 2 is arranged on the mounting table surface.

The inside of the cylinder 1 is provided with a plurality of screening devices 10 along the length direction. After entering the cylinder 1, the liquid or gas is subjected to multiple filtration by the multiple screening devices 10. (only the screen means near the discharge end is shown in the figure)

The screening device 10 comprises a screening support frame and a screen, the screening support frame is arranged on the inner circumferential surface of the cylinder 1, and the screen is arranged on the screening support frame.

Preferably, after the screen is arranged on the screen support frame, the axis of the length direction of the cylinder body 1 is vertical to the plane of the screen. Namely, the screen is vertical to the flowing direction of the gas or the liquid, thereby achieving better filtering effect.

Further, the inside of the cartridge 1 is optionally filled with a desiccant 1A.

The mounting surface is formed by the feed end edge of the drum 1 extending a distance radially inwards.

The flange assembly 2 comprises a flange 21, a flange cover 22, a gasket 23 and a fastener, wherein the flange 21 is arranged on the table surface, the flange cover 22 is connected to the flange cover 22 through the fastener, and the gasket 3 is arranged between the flange cover 22 and the flange 21 to improve the sealing performance.

It should be noted that the fastening member is a screw and a nut.

The geometric center of the flange 21 has a first center hole 211 therethrough, and when the flange 21 is disposed on the cylinder 1, the external liquid or gas enters the cylinder 1 through the first center hole 211.

The first end face of the flange 21 is welded on the mounting table-board of the cylinder body 1, so that the flange 21 and the cylinder body 1 form an integral structure; the second end face of the flange 21 forms an abutment for placing the gasket 23 at the periphery of the first central hole 211.

An end face of the flange cover 22 is provided with an abutting portion corresponding to the abutting table, and when the flange cover 22 is connected to the flange 21, the abutting portion is located on the abutting table, so that radial movement cannot occur between the flange 21 and the flange cover 22, and the flange cover has better stability.

Preferably, the abutment and abutment are annular, while the radial width of the shim 23 coincides with the radial width of the abutment, so that the shim 23 just covers the abutment.

The second terminal surface of flange 21 is equipped with a plurality of screw thread blind hole in the periphery of first centre bore 211, and flange cover 22 corresponds the screw thread blind hole and is equipped with the through-hole, and the fastener can wear to establish the through-hole and connect in the screw thread blind hole.

That is, after the abutting portion of the flange cover 22 is located on the abutting table, the flange cover 22 is rotated to enable the through hole and the threaded blind hole to be arranged along the same straight line, and the through hole is penetrated through by the fastener and the flange cover 22 is fixed on the flange 21 by being connected in the threaded blind hole in a threaded manner.

The geometrical center of the flange cover 22 has a second center hole to which one end of the VCR joint is connected, while the VCR joint communicates with the inside of the cylinder 1 through the second center hole.

The method of installation of the dry filter cartridge 100 is described as follows:

a 1a screen is attached to the inside of the cylinder 1 and a certain amount of desiccant is filled therein (when the object to be filtered is gas);

a2 welding the flange 21 at the feed end of the cylinder body 1;

a3 arranging the flange plate 22 on the flange 21 through fasteners;

a4 is connected with a VCR connector on the flange 22 and another VCR connector on the end socket 3.

The operating principle of the dry filter cartridge 100 is: liquid or gas enters the cylinder 1 from the VCR fitting on the flange 22 and is discharged from the VCR fitting on the closure 3 through multiple screen filters and treatments with desiccant.

The above-mentioned embodiments only express the embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the utility model. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
