Detailed Description

The technical scheme of the utility model is specifically explained below in connection with the embodiment, the utility model discloses a high strength filter core, this filter core adopt plastic material, and the filter core skeleton that it involves all has filtering capability, shows promptly to have the micropore. The structure of the filter element is shown in a combined figure 1, and the filter element comprises a framework formed by connecting at least two integrally formed filter element frameworks and filter cloth coated outside the framework, wherein the filter element frameworks comprise a hollow central pipe 8 and a hollow filter pipe 81 arranged around the central pipe 8, and the filter pipes 81 are uniformly distributed around the central pipe 8. One end of the central tube 8 is higher than the end of the filter tube 81 to form a connecting end 82, an external thread is processed on the connecting end, and an internal thread is processed at the lower end of the central tube 8. The number of the filtering pipes 81 may be 6, 4 or other, and is not limited herein. The uniform distribution is not limited, and a symmetrical arrangement with respect to the center tube 8 may be adopted.

Referring to fig. 2-4, the filter element comprises a framework and filter cloth 3 arranged outside the framework, the upper end and the lower end of the framework are respectively connected with an upper end cover 4 and a lower end cover through threads, and internal threads are processed in the upper end cover and the lower end cover and are in threaded connection with the framework. Two ends of the filter cloth 3 are coated outside the upper end cover and the lower end cover. The two ends of the filter element also comprise an upper gland 5 and a lower gland 6 which are used for compressing the filter cloth 3 and the upper end cover and the lower end cover. The upper end 41 of the upper end cover 4 penetrates through the upper gland 5 and is used for being connected with a liquid collecting pipe. The lower end of the lower end cover penetrates through the lower pressing cover 6 and is fixed again through the screw cap 7. The end cover and the gland are in a threaded form, so that the fixation of metal parts is avoided, the use occasions of the filter element can be further widened, and the filter element can be applied to acid and alkali filter materials.

The figure illustrates two filter element frameworks, namely a first filter element framework and a second filter element framework, wherein the first filter element framework comprises a first central tube 11 and a filter tube 1 arranged on the periphery of the first central tube 11. The second filter element framework comprises a second central tube 21 and a filter tube 2 arranged on the periphery of the second central tube 21. The first filter element framework and the second filter element framework are in threaded connection with the internal thread of the first central tube through a second connecting end 22 on a second central tube 21 of the second filter element framework. Correspondingly, if a plurality of filter element frameworks are provided, the filter element frameworks can be connected in the same way. The lower end of the second central tube 21 is in threaded connection with the lower end cap by a threaded connection 23. The filter element framework and the filter element framework are connected, so that the height of the filter element can be well controlled, and meanwhile, the filter element is stable when the filter element is connected by the threads. When the filter element filters, the filtrate to be filtered flows through the filter tube through the filter cloth 3 and passes through the central tube, and finally enters the liquid collecting tube from the upper end of the central tube for collection. During back blowing, gas enters from the upper end of the central pipe and blows towards the filter pipe and the bottom of the central pipe towards the filter cloth through the central pipe, so that filter residues on the filter cloth fall off. The utility model discloses a filtration is unanimous with prior art with the blowback principle, so no longer give unnecessary details here.

Of course, the present invention has many specific embodiments, which are not listed here. All technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the scope of the present invention.
