Abstract

The utilty model discloses a two-way precision filter. A wave-shaped filter core is adopted to form a filter cavity with a pressing sealing ring arranged on an upper and a lower supporting boards and a pressing supporting board. Liquid enters into the filter cavity from the outer part of the filter and is discharged through a connection pipe, and the liquid enters into the filter cavity through the connection pipe and is filters outwards. The two-way precision filter can be singly used and can be used in series or in parallel, and the two-way precision filter can also be used for filtering corrosive liquids.

Description

Two-way precision filter

The utility model belongs to fluid filter

In current industrial production, often use various filtering flow apparatuses, but most apparatus structure complexity.As the liquid filtering machine; General adopt a requirement will filter stamen to contain than higher airtight container, during work by pump with after stamen filters after filtration in the liquid injecting container, the liquid after will being filtered by filtration stamen inside is taken away.Owing to will often open airtight container cleaning and filtering stamen, make troubles to work, and the filtering machine structure complexity, cost is also than higher.

The purpose of this utility model is to go up according to this outside the deficiency, provides a kind of simple in structure, and it is convenient to clean, filter that can be bi-directional filtered.

Main points of the present utility model are; By on corrugated filter stamen and the upper and lower support plate by dress compress the sealing gear ring, compress support plate and constitute a filter chamber.

Below the contrast accompanying drawing further describes with an embodiment the utility model; Wherein (1) is lower support plate, (6) be upper bearing plate, on, be equipped with on the lower support plate and compress sealing ring gear (10), compress on the sealing ring gear corrugated filter stamen (9) is housed, selecting corrugated filter stamen for use is in order to increase filter area and to gain in strength, the outside of corrugated filter stamen is equipped with an external compression sealing gear ring (15) that matches with the profile of tooth that compresses the sealing ring gear and is compressed support plate (11), in order to retire by adorning convenient and preventing to compress support plate, on the inner face that compresses the sealing gear ring, be shaped on interior oblique tooth (13), oblique tooth (14) outside being shaped on compressing the support plate both ends of the surface compresses the sealing gear ring and can use the elastomeric material die forming.By when dress corrugated filter stamen is enclosed within and pushes and compress compressing support plate a week after compressing on the sealing ring gear, because stopping of interior oblique tooth arranged, make that compressing support plate does not move after the meeting, tighter for what press, at external compression sealing gear ring (15) with compress and adorn one around after support plate finishes by dress and compress adhesive tape (2), last lower support plate is fixed by pull bar (5) and tightening nut (7).An interior webmaster (4) and outer webmaster (3) are housed in the filter chamber (12), and the outer wall of outer webmaster contacts with filtering stamen, in order that increase the intensity of filtering stamen.Can be between interior webmaster and the outer webmaster according to the fluid properties that will filter other medium of packing into, as activated carbon etc.

The fluid that the utility model will filter in use can enter filter chamber by taking over (8), filters from inside to outside, also can enter filter chamber by the outside of filter after take over discharge.Therefore can both sides filter, filter stamen and can be made by filter paper, also available filter cloth is made, and this filter can use separately, but yet plural serial stage, use in parallel do not need outside airtight container to use.
