Box structure for filter

Abstract

The invention discloses a box structure for a filter. In the box structure, a filter is hermetically positioned on a box separator through a sealing material, the back side of the filter faces to a cleaning chamber, and the front side of the filter faces to a ventilating port; the box separator consists of a wall separator, a horizontal separator and a filter separator, the wall separator is fixedly connected to the wall of the cleaning chamber, the filter is hermetically positioned on the filter separator, and the wall separator and the filter separator are in transitional connection by virtue of the horizontal separator; the box separator is formed by virtue of integral bending; the filter separator is a two-layer separator formed by bending, one side, close to the filter, of the horizontal separator toward the back part of the filter, then bending the side toward the direction opposite to the wall, and finally bending the side toward the front side of the filter; the filter separator separates the filter and the outside of the cleaning chamber, so that the sealing property of the horizontal separator is not good due to the requirement of assembling a baffle structure, only air in the cleaning chamber escapes out of the cleaning chamber, and the air cleanness in the cleaning chamber cannot be influenced; and the box separator is formed by virtue of integral bending, so that the production material is saved, and the productivity is improved.

Description

technical field [0001] The invention relates to the field of filter installation structures, in particular to a filter box structure. Background technique [0002] At present, the common filter products on the market mostly adopt the structure that the filter partition protrudes from the wall of the box to block the vent and the clean room, and the filter partition separates the half surface of the box wall near the vent and the clean room. Close to the half surface of the clean room, the half surface of the box wall close to the vent blocks the vent and the clean room, and the half of the box wall close to the clean room blocks the clean room and the clean room. The pressure downstream of the filter (that is, the clean room) and the pressure inside the clean room are greater than the pressure outside the clean room, and the baffle structure for installing a fixed filter is installed on the partition of the box, so the seal between the upstream and downstream of the filter m...

[0002] At present, the common filter products on the market mostly adopt the structure that the filter partition protrudes from the wall of the box to block the vent and the clean room, and the filter partition separates the half surface of the box wall near the vent and the clean room. Close to the half surface of the clean room, the half surface of the box wall close to the vent blocks the vent and the clean room, and the half of the box wall close to the clean room blocks the clean room and the clean room. The pressure downstream of the filter (that is, the clean room) and the pressure inside the clean room are greater than the pressure outside the clean room, and the baffle structure for installing a fixed filter is installed on the partition of the box, so the seal between the upstream and downstream of the filter must be done well. Otherwise, the unfiltered air upstream of the filter will directly enter the space downstream of the filter through the unsealed gap at the fixed baffle on the box partition, polluting the space downstream of the filter
