Abstract

The invention discloses a filter achieving long-time stable running and a mixed shaft seal assembly of the filter, and belongs to the technical field of filters. The shaft seal assembly comprises a seal flange, a fastening bolt and a packing gland. The seal flange is provided with an upper lug seat and a lower lug seat. A threaded hole is formed in the position, corresponding to the packing gland,of the upper lug seat. The fastening bolt penetrates the packing gland and the threaded hole formed in the upper lug seat to connect the seal flange and the packing gland into a whole. The lower portion of the packing gland is inserted into the seal flange, an upper containing cavity is formed in the seal flange, graphite packing is arranged in the upper containing cavity, lower containing cavities are formed in the lower portion of the seal flange, and a seal ring is arranged in each lower containing cavity. According to the filter and the shaft seal assembly, for the filter in process, an original seal structure is improved, a seal cavity is machined in the upper portion of the seal flange, the seal structure of the graphite packing is additionally arranged, the graphite packing has good seal performance and toughness, and the leakage phenomenon caused by the situation that a brush shaft, the seal flange and a nylon shaft sleeve are not concentric can be effectively remedied.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to a filter with long-term stable operation and a hybrid shaft seal assembly thereof. Background technique [0002] Filters are widely used in industrial production and manufacturing fields, and the seal between the filter brush shaft and the cylinder body and filter cartridge cover is mainly completed by the filter seal assembly. Long-term operation of the filter will lead to wear of the shaft seal. If the filter has internal sewage leakage due to the wear of the shaft seal, it will seriously affect the normal operation of the equipment. Therefore, the shaft seal effect of the filter is very important for its long-term stable operation. [0003] The shaft seal components widely used in the market at present refer to figure 1 , figure 2 and image 3 , The sealing flange 12 is fixed on the filter cartridge cover 14 through the fastening bolt 13, and the H5 / d5 fit is used between ...
