Description

Technical Field

[0001] This utility model relates to the field of filtration, and in particular to a detachable external pressure high flow filter element support frame. Background Technology

[0002] In industrial production, filter elements are the core components of filtration systems, widely used in water treatment, chemical processing, food processing, and other fields. With the increasing scale and efficiency of industrial production, the demand for high-flow-rate filtration systems is growing. As an important part of the filter element, the support frame of the filter element directly affects its service life and filtration efficiency through its structural design and performance.

[0003] Currently, most filter element support frames on the market are fixed structures, such as... Figure 1 The two existing technologies shown;

[0004] Figure 1 One type uses a welding method to fix the filter element and the support frame. This structure requires the filter element to be replaced or cleaned after a period of use. The fixed support frame cannot be disassembled, which is inconvenient to use.

[0005] Figure 1 Another type of threaded connection used in this process is easy to disassemble, but it is not strong enough in actual use. In extreme cases, when the pressure difference is too high, the simple threaded connection is not strong enough and is prone to deformation.

[0006] Based on the problems existing in the current technology, we propose a detachable external pressure high flow filter element support frame. Utility Model Content

[0007] To address the technical problems associated with threaded connections and fixed welding in existing technologies, this utility model provides a detachable external pressure high-flow filter element support frame.

[0008] This utility model is achieved by the following technical solution: a detachable external pressure high flow filter element support frame, including a filter element tube and a disassembly and locking mechanism, wherein filter holes are opened on the filter element tube and a connecting screw is connected to the bottom end of the filter element tube;

[0009] The disassembly and locking mechanism includes: a cylindrical positioning plate; a limiting sleeve installed on the outer edge of the positioning plate; an adjusting screw that passes through the positioning plate and the limiting sleeve; a locking part movably connected to the top of the adjusting screw; and a fastening handle positioned above the limiting sleeve. The outer side of the fastening handle is equipped with an anti-slip sleeve to increase friction during operation.

[0010] First, connect the filter tube to the threaded sleeve of the positioning plate via the connecting screw, thereby initially tightening the filter tube with the disassembly and locking mechanism. Then, by rotating the adjusting screw, the adjusting screw rotates inside the limiting sleeve, and the locking part connected to the top of the adjusting screw moves. The three sets of locking parts move and thus fix and lock the filter tube, thereby fixing the filter tube.

[0011] As a further optimization of this utility model, the locking part is provided in three sets, and the locking part is in the form of an arc-shaped plate. The three sets of locking parts lock the filter tube.

[0012] As a further optimization of this utility model, a screw is connected to the bottom end of the fastening handle, and the screw at the bottom end of the fastening handle passes through the limiting sleeve and contacts the upper surface of the adjusting screw.

[0013] As a further optimization of this utility model, by rotating the fastening handle, a screw is connected to the bottom end of the fastening handle. The screw at the bottom end of the fastening handle rotates and presses downward, and contacts the upper surface of the adjusting screw; thereby fixing the adjusting screw, improving the locking force of the adjusting screw, and preventing the adjusting screw from slipping after long-term use.

[0014] As a further optimization of this utility model, the filter element tube is made of stainless steel, which has the characteristics of corrosion resistance and high temperature resistance.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model uses three sets of locking parts to fix and lock the filter tube, thereby fixing the filter tube. The process of disassembling and installing the filter tube is simple and quick, reducing maintenance time and costs. At the same time, the locking installation strength is sufficient, which can better adapt to special environments.

[0017] 2. This utility model uses a fastening handle to fix the adjusting screw, which increases the locking force of the adjusting screw, prevents the adjusting screw from slipping after long-term use, and provides higher installation strength. Attached Figure Description

[0025] Example 1:

[0026] Please combine Figures 2-4 This embodiment proposes a detachable external pressure high flow filter element support frame, including a filter element tube 1 and a disassembly and locking mechanism 4. The filter element tube 1 has filter holes 2, and the bottom end of the filter element tube 1 is connected to a connecting screw 3.

[0027] It should be noted that the filter element tube 1 is made of stainless steel, which has the characteristics of corrosion resistance and high temperature resistance.

[0028] The disassembly and locking mechanism 4 includes:

[0029] Positioning disk 41, positioning disk 41 is cylindrical;

[0030] Limiting sleeve 42 is installed on the outer edge of positioning plate 41;

[0031] Adjusting screw 43 passes through positioning plate 41 and limiting sleeve 42;

[0032] Locking part 44 is movably connected to the top end of adjusting screw 43;

[0033] A fastening handle 45 is positioned above the limiting sleeve 42. An anti-slip sleeve is provided on the outer side of the fastening handle 45 to increase friction during operation.

[0034] Furthermore, the locking part 44 is provided in three sets, and the locking part 44 is an arc-shaped plate. The three sets of locking parts 44 lock the filter tube 1.

[0035] It should be noted that the bottom end of the positioning plate 41 is provided with a threaded sleeve 46, and the connecting screw 3 is matched with the threaded sleeve 46.

[0036] More specifically, the filter element tube 1 is first connected to the threaded sleeve 46 of the positioning plate 41 via the connecting screw 3, thereby initially tightening the filter element tube 1 with the disassembly and locking mechanism 4; then, by rotating the adjusting screw 43, the adjusting screw 43 rotates inside the limiting sleeve 42, and the locking part 44 connected to the top of the adjusting screw 43 moves. The three sets of locking parts 44 move and thus fix and lock the filter element tube 1, thereby fixing the filter element tube 1.

[0037] It should be noted that a screw is connected to the bottom end of the fastening handle 45. The screw at the bottom end of the fastening handle 45 passes through the limiting sleeve 42 and contacts the upper surface of the adjusting screw 43.

[0038] Specifically, by rotating the fastening handle 45, a screw is connected to the bottom end of the fastening handle 45. The screw at the bottom end of the fastening handle 45 rotates and presses downward, contacting the upper surface of the adjusting screw 43; thereby fixing the adjusting screw 43, increasing the locking force of the adjusting screw 43, and preventing the adjusting screw 43 from slipping after long-term use.

[0039] Specific implementation steps of this utility model:

[0040] In use, first connect the filter element tube 1 to the threaded sleeve 46 of the positioning plate 41 via the connecting screw 3, thus initially tightening the filter element tube 1 with the disassembly and locking mechanism 4. Then, by rotating the adjusting screw 43, the adjusting screw 43 rotates inside the limiting sleeve 42, causing the locking part 44 connected to the top of the adjusting screw 43 to move. The three sets of locking parts 44 move, thus fixing and locking the filter element tube 1, achieving its fixation. Next, by rotating the fastening handle 45, a screw connected to the bottom of the fastening handle 45 rotates, pressing downwards and contacting the upper surface of the adjusting screw 43, thereby fixing the adjusting screw 43, increasing its locking force, and preventing slippage during long-term use. When disassembly is required, simply reverse the above process.
