Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel pipe application protection, in particular to a stainless steel wire mesh filter pipe. Background Art

[0002] Porous metal materials are a rapidly developing functional material. They offer advantages such as good permeability, adjustable pore size, corrosion resistance, high temperature resistance, and high strength. They have been widely used in the atomic energy, petrochemical, metallurgical, mechanical, pharmaceutical, and environmental protection industries. With filtration accuracy reaching 1µm, widths exceeding 1200mm, and the ability to be manufactured into small-diameter, long cylindrical products, they are highly efficient filtration materials and play an important role in the chemical and environmental protection fields.

[0003] Existing stainless steel wire mesh filter tubes, such as those disclosed in Publication No. CN101362284B, employ a method for manufacturing a stainless steel wire mesh filter tube. A metal molybdenum rod or a porcelain tube containing 95wt% alumina is used as a core rod, and a stainless steel plain or twill square mesh or stainless steel plain or twill mat-shaped mesh is wrapped around the outer layer. The tube is then sintered in a 95wt% alumina porcelain tube under vacuum at 1200-1390°C for 1-3 hours to produce a seamless, frameless, and rigid stainless steel wire mesh filter tube. These filter tubes are primarily categorized as frame-coated metal mesh, perforated plate composite mesh, and composite metal mesh material roll-welded. The ends are often integrally molded, resulting in a flimsy structure. This lack of structural strength can easily lead to uneven deformation during installation and use. Furthermore, the port locations, due to the cutouts, have numerous burrs that can easily cause scratches and damage, making the stainless steel wire mesh filter tubes inconvenient to use. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that the end portion of a stainless steel wire mesh filter tube has weak structural strength and causes damage, and proposes a stainless steel wire mesh filter tube.

A fitting hole is provided at the end of the mesh tube, and the end cover is initially fitted onto the mesh tube through the fitting hole. A locking mechanism is provided between the mesh tube and the end cover for fixing the two, and at least four reinforcing ribs are equidistantly provided on the mesh tube.

[0007] Preferably, the end cover comprises an outer cover which is sleeved on the end of the mesh tube, a plug which is movably sleeved in the sleeve hole is integrally welded inside the outer cover, and a mesh plate extending into the mesh tube is integrally connected to the inner side of the outer cover.

[0008] Preferably, the locking mechanism includes an annular groove provided at the end of the net tube, and a receiving groove is provided in the annular groove, a guide slot is provided in the receiving groove, a tensioning latch rod is rotatably installed in the receiving groove, and a welded strong spring and a guide slider for movably pulling the tensioning latch rod are provided in the guide slot, an inverted slot corresponding to one end of the tensioning latch rod is provided in the outer cover, and a resistance rod is integrally connected to the other end of the tensioning latch rod, a limiting sleeve is provided in the annular groove, and a crescent protrusion that slides against the resistance rod is integrally connected to the limiting sleeve.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-Figure 3 A stainless steel wire mesh filter tube includes a mesh tube 1 and an end cover 2. A set hole 3 is opened at the end of the mesh tube 1, and the end cover 2 is initially set on the mesh tube 1 through the set hole 3. It should be noted that the number of the set holes 3 is at least four, which are evenly distributed circumferentially to ensure that the end cover 2 is initially set on the mesh tube 1 through the set holes 3.

[0021] A locking mechanism is provided between the network management unit 1 and the end cap 2 to securely connect the two, as follows:

[0022] The locking mechanism includes an annular groove 4 provided at the end of the network tube 1, and a receiving groove 5 is provided in the annular groove 4, a guide slot 6 is provided in the receiving groove 5, a tensioning latch rod 7 is rotatably installed in the receiving groove 5, the tensioning latch rod 7 is an L-shaped structure, and a strong spring 8 welded to each other and a guide slider 9 for movably pulling the tensioning latch rod 7 are provided in the guide slot 6, an inverted card slot 11 corresponding to one end of the tensioning latch rod 7 is provided in the outer cover 201, and the other end of the tensioning latch rod 7 is provided with a guide slot 12. The upper part is integrally connected with a resistance rod 12. It should be noted that, only under the single action of the strong spring 8, the opening and closing latch rod 7 maintains a horizontal state in the receiving groove 5. A limiting sleeve 13 is provided in the annular groove 4, and a crescent protrusion 16 that slides against the resistance rod 12 is integrally connected to the limiting sleeve 13. When pressure is applied to the opening and closing latch rod 7 by using the limiting sleeve 13, the opening and closing latch rod 7 performs a lever-like deflection, and one end is snapped into the inverted slot 11 to prevent the end cover 2 from detaching from the network pipe 1.

[0023] At least four reinforcing ribs 17 are evenly spaced on the network management 1. Figure 1 The structural strength of the network pipe 1 is enhanced by providing reinforcing ribs 17 to prevent the network pipe 1 from collapsing due to its long length.

[0024] Please refer to the instruction manual for details Figure 2The end cover 2 includes an outer cover 201 that is sleeved on the end of the network pipe 1. A plug 202 that is movably sleeved in the sleeve hole 3 is welded inside the outer cover 201, and a mesh plate 203 extending into the network pipe 1 is integrally connected to the inner side of the outer cover 201. The end cover 2 is initially sleeved on the network pipe 1 using the plug 202, and the angle of the end cover 2 on the network pipe 1 is limited to facilitate the operation of the locking mechanism.

[0025] The strong spring 8 is welded in the guide slot 6, and the guide slider 9 is slidably mounted in the guide slot 6. A traction link 10 is pin-connected between the guide slider 9 and the resistance rod 12. Under the elastic support of the strong spring 8, the opening and closing pin rod 7 can reset itself.

[0026] The annular groove 4 and the limiting sleeve 13 are respectively provided with an outer thread 14 and an inner thread 15 that are engaged with each other, so as to limit the limiting sleeve 13 when it rotates to any position.

[0027] It should be noted that the specific model and specifications of the network management system 1 need to be selected based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it is not described in detail.

[0028] The functional principle of this utility model can be explained through the following operation modes:

[0029] Use the plug 202 to connect with the sleeve hole 3 to preliminarily sleeve the end cover 2 onto the end of the network pipe 1;

[0030] The limiting sleeve 13 is controlled to rotate in the annular groove 4, so that the synchronously rotating crescent protrusion 16 squeezes the interference rod 12, thereby driving the opening and closing latch rod 7 to be deflected by force. During this process, the interference rod 12 squeezes the guide slider 9 through the traction link 10, so that the guide slider 9 squeezes the strong spring 8 during its movement along the guide slot 6;

[0031] The opening and closing latch rod 7 is deflected by force until one end is fitted into the inverted card slot 11 , thereby achieving fixed fitting of the end cover 2 on the end of the network pipe 1 .

[0032] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
