Sealing Improvement Structure of Top-mounted Air Filter

Abstract

The invention discloses a modified sealing structure of a top type air filter. The sealing structure comprises an air filter and a filter housing. A zero pressure area is arranged in the sealing structure of the air filter. If leakage occurs in a first sealing device and a second sealing device, air in a high pressure air inlet area and a low pressure air outlet area will be leaked to the zero pressure area. Because the zero pressure area is connected to the outside, and the pressure of the zero pressure area is less than pressures of the high pressure air inlet area and the low pressure air outlet area, so the air in the zero pressure area can be guaranteed not to enter the low pressure air outlet area, so that absolute clean of a space needing to be filtered can be ensured. Meanwhile, long-time heat preservation in the air filter can be realized due to the existence of the zero pressure area. Moreover, the sealing structure of the invention enables the air filter to be disassembled and assembled conveniently.

Description

technical field [0001] The invention relates to a sealing structure of an air filter, in particular to an improved sealing structure of a top-mounted air filter. Background technique [0002] Air filters are widely used in various industries. The air filter’s tightness is the key factor for the air filter to realize its function. Often in the actual field, it is difficult to completely seal the sealer and the space to be filtered, or more At least there will be air leakage into the space to be filtered, which will affect the effect of the air filter. Even with the current anti-leakage sealing structure, it is difficult to achieve a sufficient sealing effect. Contents of the invention [0003] In order to overcome the above defects, the present invention provides an improved sealing structure of the top-mounted air filter, which reduces the possibility of unfiltered air entering the space to be filtered, and at the same time plays the role of heat preservation of the box. ...
