Abstract
The utility model relates to the field of filters and in particular relates to a backwashing filter. The backwashing filter mainly comprises a filter layer, wherein one end of the filter layer is connected with a joint; and the other end of the filter layer is connected with an end cover. The backwashing filter is characterized in that an inner framework is arranged at the inner side of the filter layer, wherein an outer framework is arranged at the outer side of the filter layer. The inner frame is arranged at the inner side of the filter layer and the outer framework is arranged at the outer side of the filter layer, so that the washing pressure resistance strength of the filter layer in the washing process and the backwashing process is strengthened, and therefore, the service life of the filter is prolonged. A supporting spring is arranged at the inner side of the inner framework, so that the washing pressure resistance strength of the filter layer in the washing process and the backwashing process is further strengthened. In order to enhance the filter precision of the filter, the filter layer consists of three layers of filter screens with different filter precisions. A sealant is poured to the connected part of the filter layer and the joint and the connected part of the filter layer and the end cover, respectively, so that not only can the protective effect of the inner framework and the outer framework to the filter layer be increased, but also the filtering tightness can be strengthened. Besides, the backwashing filter is simple and practical in structure.
Description
Technical field
The utility model relates to art of filters, specifically is a kind of backwash filter; It is mainly used in the hydraulic support art of filters, and it is with simple in structure, the high and strong characteristics of anti-stamping press of filtering accuracy and tool practicality deeply.
Background technology
Hydraulic support art of filters in filter, the filter course of existing filter is formed with three layers of sintering net usually, and its filtering accuracy is not enough.And existing filter only is provided with inner frame, when screen pack is strong inadequately owing to its anti-stamping press in flushing and the process of backwash, is easy to be torn, thereby has had a strong impact on service life of filter.Therefore, how designing the high and strong backwash filter of anti-punching press of a precision for the hydraulic support art of filters, is a problem that needs solution at present.
The utility model content
The utility model provides a kind of backwash filter at the deficiencies in the prior art; It is mainly with simple in structure, the high and strong characteristics of anti-stamping press of filtering accuracy and tool practicality deeply.
In order to achieve the above object, a kind of backwash filter of the utility model mainly comprises filter course, and described filter course one end is connected with joint, and the other end is connected with end cap; The inboard of described filter course is provided with inner frame, and the outside is provided with outer skeleton, with the anti-punching press intensity of force of enhancing filter course in the process of flushing and backwash, thus the service life of prolongation filter.
Preferably, the inboard of described inner frame is provided with support spring, with the anti-punching press intensity of force of further enhancing filter course in flushing and the process of backwash, and then has promoted the backwash effect of filter.
Preferably, described filter course is made of the three layer filtration net.
As the further improvement of such scheme, described filter course is made of the screen pack of three layers of different filtering accuracy, to strengthen the filtering accuracy of filter.
Preferably, the junction of described filter course and joint and end cap is injected with fluid sealant respectively, and this has not only increased inner frame, outer skeleton to the protective effect of filter course, but also has strengthened the sealing of filtering, thereby has effectively prolonged the service life of filter.
As the further improvement of such scheme, described fluid sealant is AB glue.
Nationality is provided with inner frame by the inboard at described filter course, and the outside is provided with outer skeleton, has so just strengthened the anti-punching press intensity of force of filter course in the process of flushing and backwash, thereby prolongs the service life of filter.In order to strengthen the filtering accuracy of filter, described filter course is made of the screen pack of three layers of different filtering accuracy.And being injected with fluid sealant respectively in the junction of described filter course and joint and end cap, this has not only increased inner frame, outer skeleton to the protective effect of filter course, but also has strengthened the sealing of filtering, thereby has effectively prolonged the service life of filter.This is simple and practical, the filtering accuracy height, and anti-stamping press is strong.
Description of drawings
Fig. 1 is overall structure cutaway view of the present utility model;
Fig. 2 is end cap end-view of the present utility model.
Wherein, Reference numeral, 1 is filter course, and 2 is joint, and 3 is end cap, and 4 is inner frame, and 5 is outer skeleton, and 6 is support spring.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in detail, but not as to restriction of the present utility model.
As can be seen, a kind of backwash filter of the utility model comprises filter course 1 from Fig. 1 ~ 2, and described filter course 1 one ends are connected with joint 2, and the other end is connected with end cap 3; The inboard of described filter course 1 is provided with inner frame 4, and the outside is provided with outer skeleton 5, with the anti-punching press intensity of force of enhancing filter course 1 in the process of flushing and backwash, thus the service life of prolongation filter.In order further to strengthen the anti-punching press intensity of force of filter course 1 in the process of flushing and backwash, the inboard of described inner frame 4 is provided with support spring 6, has so just promoted the backwash effect of filter.
In order to strengthen the filtering accuracy of filter, described filter course 1 is that the screen pack of these three layers of different filtering accuracies of 80u, 50u and 25u constitutes by precision.
The junction of described filter course and joint and end cap is injected with AB glue respectively, and this has not only increased inner frame, outer skeleton to the protective effect of filter course, but also has strengthened the sealing of filtering, thereby has effectively prolonged the service life of filter.
Nationality is provided with inner frame by the inboard at described filter course, and the outside is provided with outer skeleton, has so just strengthened the anti-punching press intensity of force of filter course in the process of flushing and backwash, thereby prolongs the service life of filter.In order to strengthen the filtering accuracy of filter, described filter course is made of the screen pack of three layers of different filtering accuracy.And being injected with AB glue respectively in the junction of described filter course and joint and end cap, this has not only increased inner frame, outer skeleton to the protective effect of filter course, but also has strengthened the sealing of filtering, thereby has effectively prolonged the service life of filter.This is simple and practical, the filtering accuracy height, and anti-stamping press is strong.
Below the utility model is described in detail, but apparent, those skilled in the art can carry out various changes and improvements, and does not deviate from the scope of the present utility model that appended claims limits.
