The invention discloses an air filter. The air filter comprises a cylinder, a middle gland on the cylinder, an upper cover on the middle gland, a filter element in the cylinder and a center tube on the middle gland and in the filter element. A through hole is formed in the center tube, the center tube is communicated with the inside of the filter element through the through hole in the center tube, a guide part is arranged on the middle gland, and the center tube can move along the guide part in the vertical direction of the middle gland so as to control the opening and closing states and / or the opening size of the through hole; an inlet is formed in the upper cover, an outlet is formed in the cylinder, and air enters the air filter from the inlet of the upper cover, passes the through hole of the center tube, then is filtered by the filter element and finally is exhausted from the outlet in the cylinder. The air filter can control air flow according to the relative position of the through hole and the guide part, achieves the pressure balancing function and is suitable for various mechanical devices unstable in pressure, cavity pressure does not need to be manually adjusted, and air filtering efficiency is good.
Description
technical field [0001] The invention relates to the technical field of air purification, in particular to an air filter. Background technique [0002] Air filters are mainly used in pneumatic machinery, internal combustion machinery and other fields. Their function is to provide clean air for these mechanical equipment, so as to prevent these mechanical equipment from inhaling air with impurity particles during work and increasing the probability of abrasion and damage. The main components of the air filter are the filter element and the casing. The filter element is the main filtering part, which is responsible for the filtration of gas, and the casing is the external structure that provides the necessary protection for the filter element. The working requirement of the air filter is to be able to undertake high-efficiency air filtration work, not to add too much resistance to the air flow, and to be able to work continuously for a long time. [0003] However, the air filt...
