Main pipe filter

Abstract

The invention discloses a main pipe filter which comprises a pipe body. The main pipe filter is characterized by further comprising a filter element, a housing and a water drainer, wherein the housing is arranged on the outer side of the pipe body, an inlet and an outlet are respectively formed in both sides of the top of the pipe body, the filter element is arranged in the pipe body and on a flowing channel between the inlet and the outlet, a filter cavity is formed in the lower end of the filter element, the water drainer is arranged at the bottom of the filter cavity, and an observation window used for observing the inside of the filter is formed in the part, on the side surface of the filter cavity, of the housing. According to the main pipe filter, the problems of complex structure, lower filter precision, incapability of preferably filtering dust, water drops and oil contamination in compressed air and pollution caused by secondary side compressed air are solved, and additionally, the problem that the inside of an existing main pipe filter cannot be observed by operating personnel and cannot be effectively monitored is solved. The invention provides the main pipe filter which has the advantages of simple structure, convenience in use, higher filter efficiency and better removing effect, and the inside of the main pipe filter can be observed.

Description

[0001] technical field [0002] The invention relates to a filter, in particular to a main pipe filter. Background technique [0003] The filter is an indispensable device on the conveying medium pipeline. The main filter is installed in the main pipeline to remove dust, water droplets and oil in the compressed air. However, the current main filter has a complex structure and low filtration accuracy, and cannot filter dust, water droplets and oil in the compressed air well, which is likely to cause pollution of the compressed air on the secondary side. At the same time, the current main filter, the operator cannot Observe the internal situation and achieve effective monitoring, but it is limited in use. Contents of the invention [0004] In order to solve the complex structure of the main filter in the prior art, the filtration accuracy is low, and the dust, water droplets and oil stains in the compressed air cannot be well filtered out, which is easy to cause pollution o...

Problems solved by technology

[0004] In order to solve the complex structure of the main filter in the prior art, the filtration accuracy is low, and the dust, water droplets and oil stains in the compressed air cannot be well filtered out, which is easy to cause pollution of the compressed air on the secondary side. At the same time, the current main filter, Operators cannot observe the internal situation and achieve effective monitoring. The present invention provides a main filter with simple structure, convenient use, high filtration efficiency, good removal effect, and the ability to observe the inside of the filter.
