Specific embodiment
This utility model filter adopts built-in structure, mainly by front straight length 1, rear straight length 2, the and of cartridge 3 Fastening connection piece 4 is constituted, wherein, cartridge 3 for the filter core component, mainly by bearing 31, skeleton 32, filter screen and Hold-down head is constituted.Filtration device structure form is as shown in Fig. 1-4.
Front straight length 1, rear straight length 2 are welded by standard flange and stainless steel pipes.Cartridge 3 is clamped during installation Between Qian Hou straight length, flat seal is adopted between cartridge and front straight length, rear straight length.
(1) cartridge
Cartridge is made up of bearing 31, skeleton 32, hold-down head 5 and filter screen.Skeleton is divided into before and after two parts, before skeleton To go head space heart pyramidal structure, big end is near front straight length in portion 321;The rear portion 322 of skeleton be hollow segment shape, the bottom of segment It is connected with the anterior small end of skeleton;Filter screen is close to the inwall welding of skeleton;Hold-down head is arranged on the top of skeleton segment to be used for Compress filter screen and filter screen is sealed;Bearing 31 is arranged on the outside of the anterior front end of skeleton;Bearing includes circumferential body 311 and sets The annular boss 312 in circumferential body opposite sides is put, front end face and the circumferential body of skeleton are welded;It is front straight length, rear straight Pipeline section is provided with flange 11 with the close one end of bearing, and flange 11 is provided with and the annular on bearing with the close side of bearing The annular groove 12 that boss coordinates;The opposite side of flange 11 is provided with locating surface 13;Fastening connection piece include isometric studs, Hex-head nut and flat shim;Fastening connection piece is coordinated front straight length by the screw thread of isometric studs and hex-head nut Flange, rear straight length flange connect so as to cartridge be fastened, and welding side is adopted between bearing, tapered skeleton and ball-type skeleton Formula connects, and hold-down head is used to compress filter screen, prevents filter screen from coming off, and hold-down head is welded with spherical skeleton after installation.
(2) full symmetric formula filter framing structure and processing
The front portion of skeleton is formed by the broadwise rib 324 that many warp-wise ribs 323 with gap and Duo Gen have gap, The area all same of the filtering holes that many warp-wise ribs and Duo Gen broadwise ribs are formed, and warp-wise rib is with regard to skeleton front portion Longitudinal section is symmetrical arranged.
Because filter bore is big, required filter skeleton is larger, processes the most economical using the coiling welded mode of sheet material.Design Filter skeleton with cone conformation adopt full symmetric formula structure, first sheet material is cut into into sector according to design drawing, according still further to design Drawing is rule on fan-shaped sheet material again, is then welded tapered, and the last line according on conical shell is opened using linear cutter Hole.Skeleton with cone conformation warp-wise and broadwise arrangement follow symmetry principle, and warp-wise symmetric position arranges 4 wider ribs (wherein Root is welding position), broadwise arranges a wider rib to be used to strengthen filter skeleton rigidity.
(3) inner ring cooling duct
Filter holder can produce the gap that width is about 3mm with front straight length, rear straight length connecting portion, full of liquid oxygen When the position easily there is gas enclosure phenomenon, be to solve gas enclosure phenomenon, this utility model 12 edges in filter holder indoor design The aperture of circle distribution, liquid oxygen can enter 3mm gaps by cooling aperture in precooling process, form liquid oxygen cooling duct, while Lift the cooling effect of filter.
(4) connected using the intensive spot welding mode of multiple spot between filter and filter screen
After filter skeleton is machined, need to cut out filter screen according to filter inboard wall of skeleton face form, then will Filter screen is fixed on filter internal face.The intensive spot welding side of multiple spot is adopted in the middle of this utility model between filter screen and filter skeleton Formula connects, and along filter skeleton rib some solder joints are piled up, and filter screen is coupled together with filter skeleton.
When drainage screen is layered on inboard wall of skeleton, on the top of skeleton segment a circular vacancy is just formed.Hold-down head is by bone Frame segment inner aperture is inserted, and the edge of above-mentioned drainage screen circle vacancy is pushed down, and will be compressed from the outside of skeleton segment afterwards Head and skeleton segment are welded to connect, so just drainage screen completely links together with skeleton, it is to avoid the mistake under fluid matasomatism The phenomenon that filter screen comes off.
