Abstract

The invention discloses a filter which is divided into two parts, namely a housing and a filter core fixing device. The housing comprises a barrel body, a pedestal and a collar. The collar fixes the barrel body and the pedestal together. The lower end of the barrel body is provided with four symmetric necks, and the upper end of the barrel body is equipped with a circular step surface. A cylindrical interface is arranged in the pedestal. The filter core fixing device comprises a filter core, an ''I''-shaped support body and a gland, wherein the upper end of the filter core is provided with a filter core interface; and the ''I''-shaped support body comprises two circular support plates which have different sizes and an annular support rod. Each circular support plate respectively has a bulge at the center. The two circular support plates can be respectively inserted into the annular support rod, thus connecting the ''I''-shaped support body together. The smaller circular support plate is contacted with the circular step surface at the upper end of the barrel body, and the bigger circular support plate presses tightly against the filter core. The gland has a circular hole at the center. The outer edge of the gland is provided with four symmetric flanges. The four flanges of the gland are clamped into the necks along the inner wall of the barrel body, and the filter core is pressed tightly. Then, the filter core is inserted into the cylindrical interface in the pedestal through the filter core interface.

Description

A kind of filter

Technical field

The present invention relates to filter plant technical field, particularly a kind of filter.

Background technology

Candle filter is a kind of Multifunction type filter, is widely used in the industries such as chemical industry, medicine, machinery, light textile, electronics.

The housing of the filter of the same type of current existence is made up of staving, pedestal usually, staving and pedestal is connected and fixed by collar, and filter core then inserts by the filter core interface of its one end the cylindrical receptacle be provided with in pedestal, is fixed on pedestal by filter core with this.Generally, filter core length is inadequate, when not reaching the supporting surface of staving inside, filter core may be movable or unstable, and in addition, liquid enters filter core inside by the hydraulic pressure produced from filter inner chamber, in this process, filter core may shake in the unbalanced situation of external and internal pressure; Sometimes the support force of frame of filter element not, filter core interface is connected instability and all can forms destabilizing factor when filter core works with the cylindrical receptacle in pedestal.

Meanwhile, existing filter of the same type, housing and filter core normally independent disassembling, after taking down by collar, pull down staving, finally unloaded from pedestal by filter core, operating personnel easily splash filtrate when unloading lower filter, there is potential safety hazard.

Therefore, overcome the above problems, when filter is worked, stability and safety becomes the sector problem demanding prompt solution more.

Summary of the invention

Instant invention overcomes defect and the restriction of prior art, provide a kind of filter.

This filter is divided into housing and filter core fixture two parts, housing comprises staving, pedestal and collar, and staving and pedestal are fixed together by collar, and wherein the lower end of staving is provided with four symmetrical draw-in grooves, the upper end of staving is provided with a step cutting pattern face, and base interior has a cylindrical receptacle; Filter core fixture comprises filter core, I-shaped supporter and gland, wherein the upper end of filter core is provided with a filter core interface, I-shaped supporter comprises small one and large one two circular base slabs and an annular brace bar, circular base slab center has a projection respectively, two circular base slabs can be inserted in annular brace bar respectively, I-shaped supporter be linked together, wherein, little circular base slab contacts with the step cutting pattern face of staving upper end, and large circular base slab then pushes up firm filter core; There is a circular port at gland center, and the outer rim of gland is provided with four symmetrical flanges, is snapped in draw-in groove by gland four flanges, and compress filter core along inner wall of barrel; Filter core is then by inserting filter core interface in the cylindrical receptacle in pedestal.

Detailed description of the invention

Fig. 1 is inventive shell (1) structural representation, comprise staving (3), pedestal (4) and collar (5), wherein there are four draw-in grooves (6) staving (3) lower end, each draw-in groove some get through staving (3) lowermost end from groove face, the recessed staving of remainder (3) inwall, have a step cutting pattern face (8) in staving (3) upper end, Fig. 2 is the structural representation of staving (3); A cylindrical receptacle (8) collar (5) is had staving (3) and pedestal (4) to be fixed together in pedestal (4).

Fig. 3 is filter core fixture (2) schematic diagram, comprise filter core (9), I-shaped supporter (11) and gland (16), wherein, filter core (9) has a filter core interface (10), there is a circular port (17) at gland (16) center, outer rim is provided with four flanges (18), as shown in Figure 5, I-shaped supporter (11) is made up of two circular base slabs (12) (13) and an annular support bar (15), two circular base slabs (12) (13) are respectively equipped with six trapezoidal holes (19) above, when I-shaped supporter (11) snaps in staving (3) inside, gas and filtrate can enter the inner chamber of staving (3) the first half from trapezoidal hole (19), the center of circular base slab has a projection respectively, projection is inserted respectively in annular brace bar (15), just define an I-shaped supporter (11), Fig. 4 is the structural representation of I-shaped supporter (11).

As shown in Figure 6, during mounting filter, circular base slab (13) one end little for I-shaped supporter (11) is inserted in staving (3) down, then filter core (9) is placed into the central authorities of large circular base slab (12), the part that gland (16) is got through along draw-in groove (6) is snapped in draw-in groove, after compressing filter core, gland (16) is rotated, flange (18) side is made to inject the part of draw-in groove recessed staving (3) inwall, with this, filter core fixture (2) and staving (3) are fixed as one, finally filter core interface (10) is inserted the cylindrical receptacle (8) in pedestal (4), with collar (5), staving (3) and pedestal (4) are fixed together.

During dismounting filter, staving (3) and filter core (9) are together pulled down from pedestal (4), avoid human contact or splash the filtrate on filter core (9), ensure that safety operation, meanwhile, as changed or dismantle filter core (9), only need rotary gland (16) and take off, just filter core (9) can be taken out by lift filter core interface (10).
