Abstract

The utility model discloses an online filter which comprises a shell, a material inlet, a material outlet, a drain hole, an upper seal head, a lower seal head, an equipment flange, a back flushing hole, a filter core and a filter core disc, wherein the upper seal head and the lower seal head are respectively arranged at two ends of the shell, the material inlet is formed in the upper part of the shell, which is close to the upper seal head, the drain hole is formed in the lower part of the shell, which is close to the lower seal head, the shell is connected with the upper seal head by adopting the equipment flange, the back flushing hole is formed in the top end of the upper seal head, the material outlet is formed in the bottom end of the lower seal head, the filter core is arranged in the shell, two ends of the filter core are respectively arranged in corresponding holes in the filter core disc; and when filtration is carried out, liquid enters in from the material inlet, and flows from top to bottom, and liquid filtered by the filter core outflows from the material outlet, no residual liquid which is not filtered exists in the shell, and impurities are discharged from the drain hole, and thus solution waste is avoided.

Description

Pot strainer

Technical field:

The utility model relates to a kind of filter, relates in particular to a kind of pot strainer.

Background technology:

Pot strainer is mainly used in some Precision Machining and chemical reaction industry, and these industries can produce a lot of waste water, and pot strainer filters these waste water, makes it recycling, reduces the technology cost, and reduces treatment pressure of sewage.Seeing also Fig. 1 is traditional pot strainer, and import A is positioned at cylindrical shell B middle part, and outlet C is positioned at the top of cylindrical shell B; Seeing also Fig. 2 is the liquid working schematic diagram, during filtration, open import A and outlet C, close back blow port D and sewage draining exit E, liquid enters from import A, from bottom to top flow, the liquid after filtering by filter core F flows out from outlet C, As time goes on, the impurity that accumulates in filter core F surface can stop up filter core F very soon, when acquiring a certain degree, then influence the filter circulation, need carry out backwash work this moment; Seeing also Fig. 3 is anti-cleaning schematic diagram, during backwash, close import A and outlet C, open back blow port D and sewage draining exit E, because exporting the top that C is positioned at cylindrical shell B, leave the solution that can't filter in a large number in the cylindrical shell B, when backwash, the solution of residual flow can be discharged from sewage draining exit together along with impurity in the housing, causes a large amount of wastes.

The utility model content:

The utility model is at the deficiencies in the prior art, and it is zero pot strainer that a kind of filter efficiency height, raffinate amount are provided.

For realizing the above object, the technical solution adopted in the utility model is:

Pot strainer is made up of housing, material inlet, material outlet, sewage draining exit, upper cover, low head, vessel flange, back blow port, filter core, filter core floral disc; The housing two ends are separately installed with upper cover and low head, material inlet is arranged on the housing top near upper cover, and sewage draining exit is arranged on the lower housing portion near low head, adopts vessel flange to be connected between housing and the upper cover, the upper cover top is provided with back blow port, and the low head bottom is provided with material outlet; Filter core is installed in the housing, and its two ends are installed in respectively in the hole corresponding on the filter core floral disc.

The beneficial effects of the utility model are: material outlet is located at the low head bottom, during filtration, liquid enters from material inlet, from top to bottom flow, flow out from material outlet by the liquid behind the filter element filtering, do not have the raffinate of filtered in the housing, impurity is discharged from sewage draining exit, avoids the waste of solution.

Fig. 2 is the liquid filtering work schematic diagram of traditional pot strainer;

Fig. 3 is the backwash work schematic diagram of traditional pot strainer;

Fig. 4 is structural representation of the present utility model;

Fig. 5 is liquid filtering work schematic diagram of the present utility model;

Fig. 6 is backwash work schematic diagram of the present utility model.

The specific embodiment:

As Fig. 4, Fig. 5, shown in Figure 6, pot strainer is made up of housing 1, material inlet 2, material outlet 3, sewage draining exit 4, upper cover 5, low head 6, vessel flange 7, back blow port 8, filter core 9, filter core floral disc 10; Housing 1 two ends are separately installed with upper cover 5 and low head 6, material inlet 2 is arranged on housing 1 top near upper cover 5, sewage draining exit 4 is arranged on housing 1 bottom near low head 6, adopt vessel flange 7 to be connected between housing 1 and the upper cover 5, upper cover 5 tops are provided with back blow port 8, and low head 6 bottoms are provided with material outlet 3; Filter core 9 is installed in the housing 1, and its two ends are installed in respectively in the hole corresponding on the filter core floral disc 10.

During filtration, material inlet 2 and material outlet 3 are opened, back blow port 8 and sewage draining exit 4 are closed, and liquid enters from material inlet 2, from top to bottom flows, flow out from material outlet 3 by the liquid after filter core 9 filtrations, As time goes on, the impurity that accumulates in filter core 9 surfaces can stop up filter core 9 very soon, when acquiring a certain degree, then influence the filter circulation, need carry out backwash work this moment; During backwash, material inlet 2 and material outlet 3 are closed, back blow port 8 and sewage draining exit 4 opened, and because material outlet 3 is positioned at the bottom of low head 6, do not have the raffinate of filtered in the housing 1, and impurity is discharged from sewage draining exit 4, avoids the waste of solution.

The utlity model has advantages such as rational in infrastructure, easy to operate, good filtration effect, have great promotional value.
