Specific embodiment

To keep the technical solution of the utility model and advantage clearer, the utility model is implemented below in conjunction with attached drawing Mode is described in further detail.

It should be noted that term position "upper", "lower" involved in the utility model embodiment are with the filtering What the working condition of device device defined, for example with orientation shown in Fig. 1, the orientation of inlet 3 is arranged as "upper", with setting The orientation of sewage draining exit 5 is "lower".

The utility model embodiment provides a kind of filter for installation, as shown in Figure 1, the filter for installation includes: ontology 1, the inside of ontology 1 has chamber；

Filter element 2 in the chamber is set, and chamber is divided into the first chamber and the second chamber by filter element 2；

The inlet 3 being connected to the first chamber；

The liquid outlet 4 being connected to the second chamber；And

The sewage draining exit 5 of 3 lower section is connected to and be located in the liquid inlet with the first chamber, is provided with sewage draining valve 51 on sewage draining exit 5.

In application, the filter for installation is installed in the entrance of pipe network, the sewage draining valve 51 on sewage draining exit 5 is closed, pipe Liquid in road is entered by inlet 3 in first chamber of ontology 1, is filtered via the filter element 2 in chamber, and filtering is cut The impurity flowed down rests in the first chamber, and filtered liquid enters the second chamber, and further (enters through the discharge of liquid outlet 4 Pump).After a period of use, when needing to clear up the impurity that filter deposition gets off, the liquid displacement of pipe network can be reduced, is slowly beaten Sewage draining valve 51 is opened, the liquid in pipeline generates shunting, makes a part of liquid wash filter element 2, further makes impurity by arranging Self-discharged in dirty mouth 5, the water outlet status of continuous observation sewage draining exit 5 close sewage draining valve when water is discharged without obvious impurity 51, i.e. completion cleaning operation.

Filter for installation provided by the embodiment of the utility model, by the way that the blowdown being connected to the first chamber is arranged on ontology 1 Mouth 5, when making to clear up impurity, filter residue and impurity in flushable first chamber of liquid in pipeline and on filter element 2, and by blowdown Self-discharged in mouth 5.When carrying out dirt cleaning using the filter for installation, process not only is truncated without termination of pumping, without big face It accumulates empty and carries out equipment disassembly, reduce cleaning difficulty, save time and manpower, making reasonable cleaning cycle can Effectively avoid blocking accident.

In above-mentioned filter for installation, inlet 3 and liquid outlet 4 can be oppositely arranged, and make filter element 2 setting into Between liquid mouth 3 and liquid outlet 4, for filtering liquid, it is contemplated that the convenience that filter element 2 uses illustratively can make filtering single Member 2 is sieve.

In application, can be fixed on sieve in the chamber inside ontology 1, chamber is divided into the first chamber and second by sieve Chamber, sieve are filtered the liquid in pipeline, and the impurity in liquid is trapped in the first chamber, and make filtered liquid into Enter in the second chamber.

In above-mentioned filter for installation, the lower section of inlet 3 is arranged in sewage draining exit 5, can for the ease of the discharge of impurity Sewage draining exit 5 is arranged in the bottom of ontology 1.

In a kind of possible embodiment, sewage draining exit 5 can be made to be located in the bottom sidewall of ontology 1, as shown in Figure 1.Due to The bottom of the first chamber is rested on through the filtered impurity of filter element 2, so set, the discharge of impurity can be convenient for, emptied.

In alternatively possible embodiment, sewage draining exit 5 can also be located on the bottom wall of ontology 1.

In addition, the waste water container that can also be prepared in advance can put waste water container in the impurity cleared up under filter deposition At sewage draining exit 5, for collecting sewage, avoids wastewater disposition and pollute environment.

In above-mentioned filter for installation, chamber can be formed as one the structure inside ontology 1, that is, chamber one Body is formed in the closing chamber of the inside of ontology 1.

In view of filter element 2 be arranged convenience, can also chamber formed in the following manner:

It is provided with notch 11 on ontology 1, and is covered with gland 12 on notch 11, notch 11 and gland 12 surround chamber.

In application, openable gland 12, filter element 2 is fixedly installed in notch 11, make inlet 3 and liquid outlet 4 The two sides of filter element 2 are located at, then gland 12 is fixed on notch 11, cover notch 11.

It is understood that the chamber that notch 11 and gland 12 surround is divided into the first chamber and the second chamber by filter element 2. And gland 12 is removably mounted on notch 11, so set, the installation of filter element 2 can be convenient for, and when necessity Disassembling section.

Wherein, the utility model does not have considered critical, example for the mode that is fixedly connected between gland 12 and notch 11 Ground can be such that gland 12 is bolted on the flange of notch 11, and gland 12 is made to cover notch 11.

In application, can make to be evenly arranged with several threaded holes on the edge of gland 12, accordingly on the flange of notch 11 Several threaded holes are also provided with, threaded hole are then passed through using the screw rod of bolt, and be fixed using nut, thus by gland 12 It is fixedly connected on notch 11.

Hydraulic pressure is larger in filter when in view of working normally, and further, can also set between gland 12 and notch 11 Sealing ring is set, when being fixedly connected with gland 12 with notch 11, compressible sealing ring is sealed, and sewage is avoided to leak outside.

In above-mentioned filter for installation, the filter element 2 can be also set to include:

Framework；

With the strainer for the outside for being coated on framework.

In application, strainer to be coated on to the outside of framework, then framework is put into notch 11, then be fixedly connected with upper press cover 12.Wherein, the cross sectional shape of framework adapts to the cross sectional shape of notch 11, so that framework abuts in the chamber, and then makes work When filter element 2 will not because of water flow percussion and swing.

Illustratively, when notch 11 is square groove, the corresponding square block of framework can be made, when notch 11 is cylinder groove, It can make the corresponding cylindrical body of framework.

Further, as shown in Figure 1, framework 21 can also be made to have tread, tread is towards inlet 3.So set, a side Face can be filtered convenient for liquid by filter element 2, avoided water impact and swung, on the other hand can make to reserve more in the first chamber More spaces for being used to accommodate the impurity filtered out.

Further, for the ease of the installation of filter element 2 and necessity disassembly when, can also be such that filter element 2 wraps Include the handle being arranged in framework；

Handle is hinged in framework.

When installation, the framework for being coated with strainer can be put into notch 11 by handle, then by handle by hingedly revolving It goes on side, then covers upper press cover 12；Similarly, it needs to dismantle filter element 2 when being rinsed, can also pass through handle will The framework for being coated with strainer is taken out from notch 11.

In above-mentioned filter for installation, in order to guarantee the structural strength of filter for installation, can make ontology 1, inlet 3, Liquid outlet 4 and sewage draining exit 5 are integrally formed structures.

The above is merely for convenience of it will be understood by those skilled in the art that the technical solution of the utility model, not to Limit the utility model.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on, It should be included within the scope of protection of this utility model.
