Description

Technical Field

[0001] The utility model relates to the technical field of bag filters, in particular to a bag filter for solid-liquid separation. Background Art

[0002] Bag filter is a multi-purpose filtering equipment with novel structure, small size, simple and flexible operation, energy saving, high efficiency, closed working and strong applicability. Bag filter is a new type of filtering system. The filter bag is supported by a metal filter basket inside. The liquid flows in from the inlet and flows out from the outlet after being filtered by the filter bag. Impurities are intercepted in the filter bag and can continue to be used after replacing the filter bag.

[0003] The patent application of Jianjingsuo in the publication (announcement) number: CN206676066U discloses a solid-liquid separation bag filter, including a mixed liquid delivery pipe, a pressure gauge, a threaded column, a filtrate outlet, a first filter bag and a second filter bag. The lower end of the mixed liquid delivery pipe is fixed with a screw, and the upper end of the device body is connected to the upper cover through a threaded column, a nut and a connecting and fixing pin. A connecting and fixing ring is installed between the upper cover and the device body. A first filter cartridge is arranged on the outer side of the first filter bag, and a second filter cartridge is fixed on the outer side of the second filter bag. The threaded column of the solid-liquid separation bag filter is movably connected to the device body through the connecting and fixing pin, which facilitates the disassembly of the upper cover and the device body. The outer dimensions of the first filter cartridge and the first filter bag are larger than the outer dimensions of the second filter cartridge and the second filter bag, which can prevent the first filter bag and the second filter bag from being damaged. The hole specification of the first filter bag is smaller than the hole specification of the second filter bag to ensure the purity of the filtrate.

[0004] Although the above scheme can prevent the first filter bag and the second filter bag from being damaged by making the outer dimensions of the first filter cartridge and the first filter bag larger than the outer dimensions of the second filter cartridge and the second filter bag, there may be debris left on the filter holes, which may easily cause the filter holes to be blocked and affect the filtering effect. For this reason, we propose a bag filter for solid-liquid separation. Utility Model Content
