Abstract
The utility model provides a safe, convenient and reliable self-cleaning filter, comprising a filter, wherein the filter comprises a barrel and a filter element arranged in the barrel; an inlet is formed in one end of the barrel; an outlet is formed in the other end of the barrel; the filter element is mounted on the inlet; the free end of the filter element stretches out of the barrel by an elbow to form a blowdown port; an inlet valve is arranged on the inlet; an outlet valve is arranged on the outlet; a blowdown port valve is arranged on the blowdown port; a bypass valve is arranged between the inlet and the outlet. According to the self-cleaning filter, impurities in the filter element of the filter are directly discharged outside a pipeline from the reserved blowdown port, the aim of removing the impurities in the pipeline is achieved, and the filter element of the filter is prevented from being blocked; the structure is simple, the operation is convenient, no dismantling equipment is needed, the impurities can be removed and discharged outside a pipeline system only by repeatedly opening and closing the valves, and the maintenance cost can be obviously reduced.
Description
Technical field
The utility model relates to a kind of filter, especially a kind of self-cleaning filter.
Background technology
In general air separation plant, every cover project all can be used filter, as the filter of using on water pump, and the water filter of using in handpiece Water Chilling Units, the filter of using on decompressor, filter of using on oxygen, nitrogen compressor etc.More than use, almost ubiquitous.But filter, through after long-term use, there will be and blocks existing picture, resistance increases, and affects technic index and normally uses.What therefore the timely foul of removing in filter showed is particularly important.
Utility model content
The purpose of this utility model is to provide a kind of safe, convenient, reliable self-cleaning filter.
Realize the self-cleaning filter of the utility model object, comprise filter, described filter comprises cylindrical shell and is positioned at the filter core of cylindrical shell, described cylindrical shell one end is import, the other end is outlet, described filter core is arranged on import department, and the free end of described filter core stretches out cylindrical shell by bend pipe and forms blowing mouthful outward;
Described import department is provided with imported valve, and described exit is provided with outlet valve, and described blowing mouth place is provided with blows down a mouthful valve, between described import and outlet, is provided with bypath valve.
Described blowing mouth is mutually vertical with Way out.
Described import, outlet and blowing mouth are respectively equipped with flange.
The beneficial effects of the utility model are as follows: self-cleaning filter of the present utility model, impurity in filter element is directly discharged into pipeline from the reserved mouth that blows down, and reach the object of removing impurity in pipeline, avoid filter element to block.It is simple in structure, easy to operate; Without detaching equipment, only need repeatedly switch several times valve just can removal of contamination and is discharged to outside pipe-line system, obviously reduce maintenance cost.

Fig. 2 is the structural representation of the state one of self-cleaning filter of the present utility model.
Fig. 3 is the structural representation of the state two of self-cleaning filter of the present utility model.
Fig. 4 is the structural representation of the state three of self-cleaning filter of the present utility model.
The specific embodiment
Embodiment of the present utility model is as follows: as shown in Figure 1, self-cleaning filter of the present utility model, comprise filter 1, described filter 1 comprises cylindrical shell 11 and is positioned at the filter core 12 of cylindrical shell 11, described cylindrical shell 11 one end are import 13, the other end is outlet 14, and described filter core 12 is arranged on import 13 places, and the free end of described filter core 12 stretches out cylindrical shell by bend pipe and forms blowing mouth 15 outward; Described blowing mouth 15 is mutually vertical with outlet 14 directions.Described import 13, outlet 14 and blowing mouth 15 are respectively equipped with flange.
As shown in Figure 2,3, 4, described import 13 places are provided with imported valve V1, and described outlet 14 places are provided with outlet valve V2, and described blowing mouth 15 places are provided with blows down a mouthful valve V3, between described import 13 and outlet 14, is provided with bypath valve V4.
The operation principle of self-cleaning filter of the present utility model is as follows: as shown in Figure 2, imported valve V1 opens (1) normal operating conditions stream, and outlet valve V2 opens, and by-passing valve V4 closes, and blows down a mouthful valve V3 and closes; (2) self-cleaning state or blowback state, as shown in Figure 2 or Figure 3, when obstruction is not serious, can be by directly removing shown in Fig. 2, at this moment, imported valve V1 opens, and outlet valve V2 closes, and by-passing valve V4 closes, and a blowing mouthful valve V3 opens; As severe obstruction, by the mode of Fig. 2, can not remove, can strengthen blowback except intensity by Fig. 3, imported valve V1 closes, and outlet valve V2 closes, and by-passing valve V4 leaves, and blows down a mouthful valve V3 and opens, and switch V4 valve, then closes V4 valve repeatedly, drives V1 valve and normally blows down by Fig. 2.Finally reach the object of removing.
Embodiment recited above is described preferred embodiment of the present utility model; not scope of the present utility model is limited; design under spiritual prerequisite not departing from the utility model; various distortion and improvement that the common engineers and technicians in this area make technical solutions of the utility model, all should fall in the definite protection domain of claims of the present utility model.
