Abstract

The utility model relates to a filtration machine with back washing means, which belongs to a further improvement for the filtration machine. The utility model adopts a pump and a multi-way control valve to control a filtering loop, and has simple structure, novel design and very convenient operation. According to the different filtering objects of the filtration machine, liquid in the filtering loop can be caused to flow back when the multi-way control valve is controlled, and the filtered liquid is caused to carry out backwash for the micropores of filtering materials when the filtered liquid flows back. Then, deposited filtering cakes can be expelled out of the filtration machine. The micropores of the filtering materials can be ensured to be clean and fluid without disassembling the filtration machine for cleaning, so that the cost of the filtering materials is reduced, the loss of the filtration machine is reduced, raw materials are saved, time and labor are saved, and work efficiency is increased.

Description

Filtration machine with back washing means

The utility model is a kind of filter with back purge system, belongs to the further improvement to filter, particularly the filter material cleaning technique field of filter.

No matter existing filter is import, still homemade, and plate compression that adopts or leaf filter usually, or the structure of vacuum filtration in use all exist the problem that filter filter material micropore very easily stops up and is difficult to clean.After filter filter material micropore stops up, all need shut down back dismounting filter, take out filter material and brush with hairbrush, wash with water (when edible liquid filters, also will wash, hot water scalds in pot) with boiling water, time-consuming, take a lot of work, take material, influence is produced.Even like this; only stifled particulate is still brushed to be come out in 0.5～several microns the filter material micropore; dismounting repeatedly so repeatedly, scrub, again the assembling; filter material is easy to dismount badly; the filter material that need more renew frequently, filter is also easily impaired, and waste is big; user's burden is heavy, and these problems deeply worry about the domestic user for a long time.

For addressing these problems, domestic a few users has increased by one and has overlapped independently backwash loop in filter, and Here it is adopts two pumps, two set of tubes, have the filter in filtration, backwash loop respectively.Never tear machine cleaning filter material tamper open though can separate, system's formation is complicated, cost is higher, and the blocked operation of work and backwash still is pretty troublesome, uses inconvenience, and production efficiency is lower.

The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art and provides that a kind of system architecture is simple, cost is low, uses the easy to operate filter with back purge system.

The purpose of this utility model can reach by following measure: filtration circuit is made up of control valve and prefilter and pump and filtering container and filter material wherein and connecting pipe and three containers, it is characterized in that: be connected with the multichannel control valve between the import and export of filtration circuit and the import and export of filtering container, be communicated with between two ports of multichannel control valve, a pump is connected between the two-port of multichannel control valve, have in the multichannel control valve every the inner passage five equilibrium of core the multichannel control valve, and an external operating grip, rotatable in the inner passage of multichannel control valve every core.

The purpose of this utility model can also reach by following measure: the multichannel control valve is eight passages, and per four passages are distributed on the circumference; The multichannel control valve be one every core, with passage be whole same cored structure; The multichannel control valve be two every core, control valve is divided into two; Between filtering container in the filtration circuit and the multichannel control valve two-port three-way control valve is arranged; Have between the prefilter at entrance point place and the container in the filtration circuit one-way control valve, and the deslagging container between two logical control valves are arranged.

The utility model is described in further detail below in conjunction with the embodiment accompanying drawing:

Embodiment is a kind of filter with back purge system that is used to filter wine liquid.

As shown in Figure 1: the passage of eight logical control valve D is: (1), (2), (3), (4), (5), (6), (7), (8), per four passages are distributed on the circumference, there is one to be whole same cored structure with passage among the eight logical control valve D, every the external operating grip of core (9) (15), also rotatable every core (9).

As Fig. 2, shown in Figure 3: every the inner passage five equilibrium of core (9) with eight logical control valve D.

As shown in Figure 4: when connecting power supply, pump (10) starting, for vertical state its inner passage is divided into two passages every core (9) among the eight logical control valve D, filter carries out filtration work.Wine liquid to be filtered in the B container is held in the suction pumps (10) through one-way control valve (12) is entered eight logical control valve D by prefilter (11) (1) end, warp (2), (3) that enter control valve D after the pressurization are again held, are flow to filtering container E by (4) end, after filter material F filtration, flow back to (5) end of eight logical control valve D, flow in the container A through (6) end, (7) end, (8) end again through valve (14), thus the wine liquid that obtains filtering.

As shown in Figure 5: when filter work after 30 minutes, stop up, move operating grip (15) for solving, make among the eight logical control valve D every core (9) for level with its inner passage five equilibrium, change channel direction.Under the effect of pump (10), the wine liquid of having filtered in the A container reversely flows into (8) end of eight logical control valve D, through (2) end and pump (10), hold by (3), (5) hold and valve (14) after enter filtering container E, filter material F is carried out backwash, filter residue after the flushing flows out from filtering container E, flow out through eight logical control valve D (4) end, (6) end, (7) end, (1) end, through prefilter (11) and valve (13) filter residue is discharged in the container C again.

After about 1～2 minute, move the operating grip (15) of eight logical control valve D, recover original channel direction, proceed filtration work.

So repeatedly,, move the flow direction that operating grip changes wine liquid, the filter material micropore is carried out once of short duration backwash, keep the cleaning of filter material micropore unimpeded every 30 minutes.

The utility model is not only applicable to filter liquide, also is applicable to filtering gas.

The utility model is compared prior art and is had following advantage:

1, eight lead to the simple in structure of control valves, novel in design, use easy to operate, according to filtering objects different in the filter, determine different blanking times, control eight logical control valves make the liquid reverse flow in the filtration circuit, make the filtrate of having filtered when reverse flow, the filter material micropore is carried out backwash, and outside the filter residue discharge machine that will accumulate, the machine of need not tearing open cleans, just can guarantee the cleaning of filter material micropore and unimpeded, make filter keep at work identical flow, thereby reduce the cost of filter material, reduce not disassembly, cleaning of filter of the loss continuous operation of filter, can push up two original filter usefulness, improve the economic benefit of enterprise.

2, adopt a pump and filtration circuit of a Multi-way control valve control, can keep machine continuous filtration work, can realize again the backwash to filter material in the filtration circuit, reduced the cost of filter, save material, not only save time but also laborsaving, improved widely operating efficiency.
