Abstract

A kind of candle filter, it comprises cylindrical shell, cover, the lower platen and the top board of filter tube are installed in the cylindrical shell, and cylindrical shell is connected with base, one side of base is provided with the filtered water discharge connection, opposite side is provided with the original water inlet that is connected with the center short tube and takes over, the lower platen center is provided with and the matched mouthpiece of base center short tube, this mouthpiece center is fixed with the axial screw pipe that is located by connecting with rib, lower platen lateral circle surface and base inner peripheral surface are sealed and matched, and the end opening of uniform each filter tube connects short tube on its plate face, and the top board bottom surface is evenly equipped with the sealing joint that can insert each filter tube upper oral part, the top board center is provided with screw hole, the axial screw lower end is connected in the pipe that is located by connecting of lower platen, and the upper end is fixed with nut after passing the center bolt hole of top board.The many members of the present invention adopt the plastic mould pressing moulding, compactness simple for structure, and processing and manufacturing is easy, and it is fast and simple that filter tube is changed dismounting, and water distribution is even, and exhaust is good, good seal performance and interior leakage can not take place.

Description

Candle filter

Technical field

The present invention relates to a kind of cartridge type sedimeter of built-in filter core.

Background technology

Existing candle filter, generally all adopt carbon steel and stainless steel to make, its structure comprises cylindrical shell, the cover of band adpting flange, the cylindrical shell inner bottom part is welded with the lower platen that is provided with filter tube centring ring hole, top is provided with the movable top board with filter tube centring ring hole, and each filter tube promptly vertically is installed between lower platen and the top board by centring ring and centring ring hole, and cylinder lateral wall or top and bottom are respectively equipped with into water interface and water outlet interface.The shortcoming that this candle filter exists is, side water inlet or top water inlet, and water distribution is inhomogeneous; Near the water inlet filter tube is hit bigger; Air is discharged difficulty in the filter; The pipe arrangement of water inlet pipe and water outlet pipe is complicated, not attractive in appearance; The whole processing of filter, installation, the replacing dismounting of parts and filter tube all bothers; Filter tube lower platen centring ring place sealing is relatively poor, is easy to generate interior leakage, not too is suitable for the chemical field of deep-etching.

Summary of the invention

The technical problem that quasi-solution of the present invention is determined is: carry out technological improvement at the shortcoming that existing candle filter exists, thereby provide a kind of processing and manufacturing easily, filter tube change dismounting fast and simple, interior leakage does not take place, water distribution is even, exhaust good and novel candle filter that filter tube is not hit.

Technical scheme of the present invention is: it comprises cylindrical shell, cover, the lower platen and the top board of filter tube are installed in the cylindrical shell, and cylindrical shell is connected with base, one side of base is provided with the filtered water discharge connection, opposite side is provided with the original water inlet that is connected with the center short tube and takes over, the lower platen center is provided with and the matched mouthpiece of base center short tube, this mouthpiece center is fixed with the axial screw pipe that is located by connecting with rib, lower platen lateral circle surface and base inner peripheral surface are sealed and matched, the end opening of uniform each filter tube connects short tube on its plate face, the top board bottom surface is evenly equipped with the sealing joint that can insert each filter tube upper oral part, and the top board center is provided with screw hole, and the axial screw lower end is connected in the pipe that is located by connecting of lower platen, after the upper end passes the center bolt hole of top board, fix with nut.

Adopt helicitic texture to be connected between cylindrical shell and the cover.

The invention has the beneficial effects as follows, because the design of each structure member all is suitable for adopting the plastic mould pressing moulding of high-strength corrosion-resisting, convenient processing and manufacture, the production efficiency height can be widely used in chemical industry; And owing to will go up lower platen and the filter core keeper is made one, the not only easy greatly installation of filter tube, change operation, and eliminated the interior leakage of the short circuit phenomenon that causes owing to seal failure between lower platen and the filter core keeper effectively; And original water inlet changes and enters upwards water distribution from the filter bottom center, like this, makes the filter tube water distribution even, can not produce the local assault filter tube, and help upwards getting rid of the air in the filter; The Inlet and outlet water mouthpiece all is arranged in filter base side simultaneously, makes the outside pipe arrangement of filter more succinct attractive in appearance, is convenient to bookkeeping; In addition, adopted helicitic texture to be connected again between cylindrical shell and the cover, made the faster convenience of disassembling, assembling and replacing filter tube.

The specific embodiment

The invention will be further described with embodiment below in conjunction with accompanying drawing.

Cylindrical shell 9 adopts a joint plastic tube, base 11 is that internal diameter is slightly larger than cylindrical shell 9 external diameters and the short cylinder of bottom lock, its avris is provided with filtered water discharge connection 14, take over 14 offsides be provided be fixed in base end face on the original water inlet that is connected of center short tube 13 take over 12; The internal diameter of the external diameter of lower platen 10 and base 11 matches to merge and fixes with adhesive bond, the mouthpiece 20 at lower platen center is socketed in the base center short tube 13 and with adhesive bond and fixes, mouthpiece 20 centers be provided with axial screw be located by connecting the pipe 17, be fixedly connected by rib 19 between the inner tubal wall of the outer tube wall of tube connector 17 and mouthpiece 20, form between each rib 19 and go up aquaporin 18, be evenly equipped with the connection short tube 15 of 5 break-through plate faces on the lower platen plate face, the internal diameter of filter tube 7 matches with the external diameter that is connected short tube 15, thereby the end opening of filter tube 7 is plugged on the connection short tube 15; In order to make filter tube 7 that more steady leaning on is installed, the groove 16 of offering socket joint filter tube bottom on the short tube 15 roots plate face on every side can connected; Top board 6 is designed to five-pointed star shape, each end, its bottom surface be provided with can each filter tube 7 upper oral part of appropriate insertion sealing joint 22, top board 6 centers are provided with axial screw hole 21; Axial screw 8 lower ends are connected in the center bolt hole 21 that being located by connecting of lower platen managed in 17, the upper end passes top board, screw in nut 5 then from screw rod 8 upper ends and compress top board 6; Cover 3 tops are provided with steam vent 1 and Pressure gauge installing hole 2, and the lid inboard is shaped on internal thread, and cylindrical shell 9 upper ends then are bonded with the external screw thread adapter sleeve 4 that matches with the cover internal thread.Above-mentioned cover 3, external screw thread adapter sleeve 4, last
