Description

A kind of plate and frame filter press

Technical field

The utility model relates to a kind of plate compression device of filter liquide.

Background technology

Plate and frame filter press is widely used a kind of in the filter plant, alternately arrange and support is formed on pair of tracks by several filter plates and filter frame, be separated with filter material between filter plate and the filter frame, adorning fashionable use hold down gag compresses this group plate and frame on the machine, and be fixed on the frame, after sheet frame compressed, the formed space of the filter plate of empty filter frame and its both sides constituted several filter operation spaces, porose on the angle of plate and frame, when sheet frame is superimposed, form the feed liquid passage.The weak point of its existence is, feed liquid is in pre-filtering stages operating inconvenience, the one, and inconvenience observation, the 2nd, the inconvenience of pre-filtering liquid is handled; Secondly, when filtering pressure rising pressure release passage or return flow line, the sieve sheet in the filter plate is fragile.

Summary of the invention

Its purpose of the utility model just is a kind of plate and frame filter press is provided, and has pre-filtering and backflow pressure release passage, and is simple in structure, just uses convenient.

The technical scheme that realizes above-mentioned purpose and take, comprise that several filter plates and filter frame are alternately arranged and support is formed on pair of tracks, be separated with filter material between filter plate and the filter frame, porose on four jiaos of filter plate and filter frame, when it is superimposed, form the feed liquid passage, adorn fashionable use hold down gag sheet frame is compressed, and be fixed on the frame, hole on a left side, filter plate lower end or the right corner communicates with space in the filter plate, and dress closes the back connection and looks clock, forms discharging opening and refluxing opening behind valve; The two jiaos of place's perforates in filter frame upper end also communicate with space in the filter frame and to form the feed liquid inlet, and the hole on the right side, lower end or the left comer communicates with space in the filter frame and forms the return flow line, and dress closes back connection valve, and is connected to form refluxing opening in the lump with above-mentioned valve export.

Compared with prior art this device has the following advantages:

1, owing to adopted feed liquid and be connected the structural design of looking clock and valve, make sheet frame convenient in the observation of pre-filtering stage, thus simple to operate in use, use convenient.

2,, thereby make plate and frame filter press have backflow functionality owing to adopted the structural design of return flow line, can pressure release when keeping off filter pressure simultaneously and increasing, do not damage with protection sieve sheet.

3, adopt the packaged formula of hoop to connect, integral design only need connect corresponding pipeline during use, does not have outflow liquid, thereby has and use conveniently, and characteristic of simple is installed.

Specific embodiments

This apparatus structure principle as shown in Figure 1, comprise that several filter plates 1 and filter frame 3 alternately arranged and support is formed on pair of tracks, be separated with filter material 2 between filter plate 1 and the filter frame 3, porose on four jiaos of filter plate 1 and filter frame 3, when it is superimposed, form the feed liquid passage, adorn fashionable use hold down gag sheet frame is compressed, and be fixed on the frame, hole on a filter plate left side, 1 lower end or the right corner communicates with space in the filter plate, and dress closes the back connection and looks clock S, through valve F ₂And F ₃The back forms discharging opening b and refluxing opening C; The place's perforates of two jiaos of filter frame 3 upper ends also communicate with space in the filter frame and to form the feed liquid inlet, and the hole on the right side, lower end or the left comer communicates with space in the filter frame and forms the return flow line, and dress closes back connection valve F ₄, and with above-mentioned valve F ₃Outlet is connected to form refluxing opening C in the lump.

The feed liquid inlet can be arranged on the sheet frame both sides, and material liquid outlet and refluxing opening are breathed out to be arranged on the sheet frame downside.Simultaneously, filter plate 1 and filter frame 3 can be stainless steel or plastics.

Its operation principle is:

Valve F is opened in pre-filtering ₁, feed liquid from charging aperture a through valve F ₁Enter sheet frame, enter in the frame through filter frame 3 upper end holes 9 and 10, as shown in Figure 2, feed liquid enters filter plate 1 behind filter material 2, by sieve sheet S is housed on the filter plate 1, have through flow hole 7 on the sieve sheet 5, feed liquid just enters space in the filter plate 1 like this, flows out sheet frame through 1 time stomidium 8 feed liquid of filter plate, because be pre-filtering this moment, also have suspension, at this moment valve-off F in the feed liquid ₂And F ₄, open valve F ₃, feed liquid is through looking clock S and valve F ₃Flow out from refluxing opening C the back.

Filter, after a period of time was carried out in pre-filtering, filter course formed, and can observe from look clock S, and it is clear that feed liquid becomes, and filtration is carried out, and at this moment, opens valve F ₂, valve-off F ₃, carrying out filter operation, the supernatant liquid after the filtration is through valve F ₂Flow out from discharging opening b the back.

Reflux, when needs carry out reflux operation, or filter pressure increases in the time of need carrying out the pressure release operation valve-off F ₂And F ₃, open valve F ₄, after this moment, feed liquid entered in the frame from the charging hole 9 and 10 of filter frame 3 upper ends, directly the discharge opening 11 from filter frame 3 lower ends flowed out, through valve F ₄Flow out from refluxing opening c the back, reaches the purpose of backflow or pressure release.

This device can also be installed sealing gasket between filter plate 1 and filter frame 3, also sealing ring can be installed on the feed liquid passage.Simultaneously, the sieve sheet 5 on this device filter plate 1 can be dull and stereotyped punched holes type, also can be millet cake boring formula, also can be various ways such as concentric garden boring formula.

This device only needs to require to connect corresponding pipeline according to filtering technique when mounted and can use.

This device embodiment two, filter plate 1 and filter frame 3 its feed liquid inlets can be arranged on sheet frame both sides or both wings, and as Fig. 5, shown in Figure 6, material liquid outlet can be arranged on the sheet frame lower side.Equally, its superimposed back forms the feed liquid passage.
