Device and method for automatic glue removal and filling of filter elements

Abstract

The invention discloses an automatic glue throwing and filling device and method for a filtering piece, and belongs to automatic glue throwing and filling devices in the technical field of chemical defense. The automatic glue throwing and filling device mainly comprises accessories including a first glue tank, a second glue tank, a control box, a mixer, a mixer support, a working table, a glue filling clamp, a variable frequency motor, a first glue outlet tube, a second glue outlet tube, a second vacuum pump, a first vacuum pump, a second buffering tank, a first buffering tank, a first glue inlet tube, a second glue inlet tube, a connecting cable and the like. Multi-component glue can be mixed uniformly, and is automatically thrown into a narrow gap between the outer shell of the filtering piece and a filtering element for precision glue filling by the glue filling clamp which is designed specially, so that a surface, which is in contact with the filtering element, of the outer shell of the filtering piece is sealed completely, and quite high consistent sealing level and glue filling appearance quality are obtained.

Description

technical field

[0001] The invention relates to a device and a method for automatically throwing glue and pouring glue into a filter element of a canister used in the field of chemical defense technology. The narrow gap between the canister filter shell and the filter element is precisely filled with glue. Background technique

[0002] At present, in the field of national defense technology, the glue filling device for canister filters is backward, and the glue pump adopts a gear pump. The gear is easy to be polluted, corroded, and bonded after long-term contact with the glue, resulting in excessive resistance to glue delivery and unstable glue output. A series of problems such as motor overheating and burning; and there is no suitable canister filter glue filling fixture, the canister filter glue filling seal quality and glue appearance quality are generally poor. For a long time, canister filter glue filling is a The technical bottleneck of the entire industry needs to be...
