Molding filtering drum

Abstract

The invention discloses a molding filtering drum. The molding filtering drum comprises a filtering drum, a filtering core tray arranged at the bottom in the filtering drum, and a filtering core seat arranged on the filtering core tray, wherein the filtering core tray and the filtering core seat are in threaded connection; the filtering core tray and the filtering drum are separately arranged; as the filtering core tray and the filtering cylinder are separately arranged, after the filtering core tray is molded, the reprocessing is convenient, so that the joint of the filtering core tray and the filtering core seat is tight, the internal leakage is not easily caused; and in addition, as the filtering core tray and the filtering drum are separately arranged, the filtering core seat is easy to mount and dismount.

Description

technical field [0001] The invention relates to the field of filters, in particular to an integrated filter cartridge. Background technique [0002] At present, the one-piece filter cartridge is directly injection molded, but the thread at the bottom of the filter cartridge cannot be reprocessed, such as figure 2 The one-piece filter cartridge shown includes: filter cartridge (1), filter element tray (2) integrally arranged at the bottom of the filter cartridge, filter element seat (3) arranged on the filter element tray (2), filter element tray (2) It is connected with the filter element holder (3) by thread; because the thread on the filter element tray is injection molded and cannot be reprocessed, the thread is easily deformed during injection molding, so that the filter element holder and the filter element tray cannot be well connected, and the plane used for sealing is also uneven If it is uneven, it is easy to cause internal leakage; it is also extremely inconvenien...

Problems solved by technology

[0002] At present, the one-piece filter cartridge is directly injection molded, but the thread at the bottom of the filter cartridge cannot be reprocessed, such as Figure 2 shows an integrated filter cartridge including: filter cartridge (1), integrally arranged on the filter cartridge The filter element tray (2) at the bottom, the filter element seat (3) set on the filter element tray (2), the filter element tray (2) and the filter element seat (3) are connected by threads; since the thread on the filter element tray is injection molded, it cannot be reprocessed , the thread is easily deformed during injection molding, so that the filter element seat and the filter element tray cannot be well connected, and the surface used for sealing is also uneven, which is easy to cause internal leakage; it is also extremely inconvenient to replace the filter element seat, and special tools are required
