Problems solved by technology
[0002] In general existing industrial and filtering equipment, although the top surface and the bottom surface of the filter element can be sealed, the bottom end and the outer wall around the bottom end are covered and fixed to avoid deformation and damage of the filter element and improve the filtration efficiency of the entire filter element. However, the disadvantage of the existing filter bag filter device is that the ring mouth of the filter bag is made of hard plastic, which is easy to break and deform. When it is closely connected with the metal filter barrel, both are hard and can only be in close contact. , does not achieve a reliable seal, causing the liquid to bypass the contact position and flow out, and cannot be completely sealed, so there is still a need for improvement

The invention relates to a filtering device, which comprises a filtering unit, wherein the filtering core comprises a first ring body and a filtering bag jointed with the bottom of the first ring body, the top surface of the first ring body is folded outwards to form an outer eave part, a second ring body is annularly arranged at the bottom of the outer side of the outer eave part, the filtering unit is jointed with a shell, a second step part annularly arranged downwards is arranged on the inner side wall of the top of the shell, an accommodating space communicated with the outside is formedin the shell, the bottom of the shell is provided with an output port communicated with the accommodating space, a cover body is jointed on the top surface of the shell to seal the accommodating space, an input port is arranged at the top of the cover body, and the diameter of the second ring body is larger than the diameter of the second step part, so that the second ring body is tightly clampedon the second step part and expands and abuts against the second step part so as to ensure the liquid sealing and prevent the influence of liquid bypassing on the filtering quality.
Description
technical field [0001] The invention relates to a filter device, in particular to a filter bag structure in a filter bag filter device. Background technique [0002] In general existing industrial and filtering equipment, although the top surface and the bottom surface of the filter element can be sealed, the bottom end and the outer wall around the bottom end are covered and fixed to avoid deformation and damage of the filter element and improve the filtration efficiency of the entire filter element. However, the disadvantage of the existing filter bag filter device is that the ring mouth of the filter bag is made of hard plastic, which is easy to break and deform. When it is closely connected with the metal filter barrel, both are hard and can only be in close contact. , did not achieve a reliable seal, causing the liquid to bypass and flow out from the contact position, and cannot be completely sealed, so there is still a need for improvement. [0003] In view of this, h...
