The matching precision between the filter basket, the filter bag ring opening and the cylinder body is higher, and the sealing performance is good. The disadvantage is that the volume is small, and the device is not suitable for occasions with large flow.
The second type is welded forming's plastic filter, and the volume can accomplish the same size of many bag filters, and the cooperation position between the basket of filter, basket backup pad, the filter bag girth uses machining, and the cooperation precision is also higher, and is sealed better. However, the filter is limited in strength by the welding of the plastic, so that the filter is used only under 2kg pressure.
And the third is to solve the corrosion resistance problem by means of anticorrosive measures such as spraying Teflon, lining PP or PTFE and the like on the basis of the existing metal filter. However, compared with the common container, the filter has a relatively complex structure, the filter bag, the filter basket and the basket support plate are required to be tightly matched, and the filter is easily corroded in a short time due to insufficient corrosion resistance because of the limitation of the current processing conditions. And after lining or spraying teflon, the tight position of original cooperation between filter screen basket and the basket backup pad is covered by lining board or teflon, because of can't further machine tooling and cause the cooperation precision extremely low, sealed effect is very poor, can't realize the higher filtration operation of precision. And the metal basket is difficult to line because of the dense arrangement of small holes, and the spraying of Teflon is extremely uneven, has poor effect and is easy to be invaded by corrosive media.
