Description

Technical Field

[0001] This utility model relates to the technology for connecting and fixing filter cartridges, and more specifically, to a fixing structure for connecting filter cartridges. Background Technology

[0002] like Figure 1 As shown, the existing filter cartridge 1 is installed on the filter cartridge frame 2. A wing nut 3 is provided at the tail of the filter cartridge 1. By rotating the wing nut 3, the sealing ring 4 at the head of the filter cartridge 1 and the tube sheet 5 are sealed together.

[0003] In actual use, the above method often results in inaccurate positioning, causing the sealing ring 4 to not be tightened properly. At the same time, the tight pressure of the nut on the sealing ring can create a leakage point, leading to powder leakage.

[0004] Therefore, currently, the only way to tighten them is by the installers themselves, relying on their installation experience. Utility Model Content

[0005] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a fixing structure for filter cartridge connection, which solves the problem of sealing ring tightening by human operation with experience-based professional skills.

[0018] The inner end face of the quick-release cover is provided with a mounting surface that is adapted to the raised surface;

[0019] The mounting surface and the quick-release cover are coaxial.

[0020] Preferably, the inner edge of the raised surface is provided with a plurality of second connecting slots;

[0021] The inner edge of the mounting surface is provided with a plurality of second connection slots that are adapted to the second connection bayonet.

[0022] Preferably, each of the positioning points includes a mounting sleeve, a spring, and a steel ball;

[0023] The mounting sleeve is attached to the inner end face of the quick-release cover by screws;

[0024] The top of the mounting sleeve is provided with a through hole with a diameter smaller than that of the steel ball;

[0025] The spring is vertically disposed inside the mounting sleeve;

[0026] The steel ball is disposed inside the mounting sleeve, with the bottom of the steel ball contacting the top of the spring, and the top of the steel ball protruding outside the through hole of the mounting sleeve.

[0037] To better understand the above-mentioned technical solution of this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0038] Combination Figures 2 to 8 As shown, the present invention provides a fixing structure for connecting filter cartridges, including a quick-release cover plate 10 and a quick-insert end cap 20.

[0039] The quick-release cover 10 is designed as a disc.

[0040] The outer end face of the quick-release cover plate 10 is mounted on the inner end face of the perforated plate 30;

[0041] Multiple first connecting slots 11 are provided on the inner end face of the quick-connect cover plate 10 near the outer circle.

[0042] Multiple positioning points 12 are also provided on the inner end face of the quick-release cover plate 10.

[0043] The inner end face of the quick-connect end cap 20 is installed at the end of the filter cartridge 40.

[0044] Multiple first connection slots 21 that are adapted to the first connection slots 11 are provided on the outer end face of the quick-connect end cap 20 near the outer circle.

[0045] The outer end face of the quick-connect end cap 20 is also provided with multiple positioning grooves 22 that are adapted to the positioning point 12.

[0046] A sealing ring 50 is also provided on the outer end face of the quick-connect end cap 20 to form a seal between the outer end face of the quick-connect end cap 20 and the inner end face of the quick-lock cover plate 10.

[0047] A raised surface 23 for installing a sealing ring 50 is provided on the outer end face of the quick-connect end cap 20.

[0048] The raised surface 23 and the quick-connect end cap 20 are coaxially arranged.
