Description

Technical Field

[0001] The utility model relates to the technical field of filter screens, and more specifically, to a circular arc stainless steel butt-welded screen. Background Art

[0002] The filter screen, abbreviated as a filter mesh, is processed from metal wire meshes or textile wire meshes with different mesh sizes. Its function is to screen materials and filter out non-compliant particles in the materials. Common filter screens are usually single-sided, and the single-sided filter screen has weak bearing capacity. During use, if too much material accumulates on the upper side, the filter screen will be pressed and deformed, resulting in the mesh holes at the sunken part becoming smaller, causing compliant particles to be unable to pass through the mesh holes, wasting a large amount of compliant cups that are screened out. Subsequently, secondary screening is required, greatly reducing the screening efficiency. Summary of the Utility Model

[0003] In order to solve the above technical problems, the utility model provides a circular arc stainless steel butt-welded screen to solve the problem of the filter screen deforming and the mesh holes shrinking.

[0005] Further, several positioning blocks are respectively fixedly connected to one side of the frame of the sub-filter screen, and the several positioning blocks are distributed in a circular array, and positioning grooves matching the several positioning blocks are respectively opened on the other side of the sub-filter screen.

[0006] Further, an embedding groove is opened on the inner wall of the silica gel ring, the frame of the filter screen is located inside the embedding groove, and the thickness of the silica gel ring is greater than the thickness of the multiple filter screens.

[0007] Further, the mesh numbers of the multiple filter screens are the same, and the mesh holes of the sub-filter screens are all square.

[0008] Further, the four sub-filter screens are all circular in structure, and the whole sub-filter screen is made of 304 stainless steel material.

[0009] Further, placing grooves are respectively opened on the opposite sides of the sub-filter screen, and a sealing ring is arranged between the two opposite placing grooves.

[0010] Further, through holes for the several positioning blocks to pass through are opened on the sealing ring, and grooves are respectively opened on the opposite sides of the sealing ring.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] In the utility model, four sub - filters are stacked and butt - welded together to form a filter, thereby improving the strength and bearing capacity of the filter, avoiding the shrinkage of the mesh holes caused by compression deformation. And when stacking, the sub - filters are positioned by positioning blocks and positioning grooves to prevent the filter from shifting and misaligning during welding. A silicone ring is arranged on the periphery of the filter so that the filter can be closely attached to the installation body during installation, and a sealing ring is used to seal between the sub - filters to prevent debris from entering through the gaps between them.

[0022] The following further describes in detail the embodiments of the utility model in conjunction with the drawings and embodiments. Embodiment

[0023] As shown in Figure 1 to Figure 6 shown:

[0024] The utility model provides an arc-shaped stainless steel spot-welded mesh, which comprises a filter mesh 1. The filter mesh 1 is composed of four sub-filter meshes 11. The four sub-filter meshes 11 are evenly arranged and stacked together. The four sub-filter meshes 11 are fixedly connected by spot welding. A silica gel ring 12 is arranged outside the filter mesh 1. The mesh numbers of multiple filter meshes 1 are the same. The mesh holes of the sub-filter mesh 11 are all square-shaped. The four sub-filter meshes 11 are all circular in structure. The whole sub-filter mesh 11 is made of 304 stainless steel material.

[0025] During manufacturing, take four sub-filter meshes 11 with a mesh number of 20 and stack them neatly together. Use spot welding to weld the four sub-filter meshes 11 together. The number of welding points shall not be less than 8, and the welding points shall be kept evenly distributed in a ring shape, so as to improve the welding strength. When the filter mesh 1 is in use, the force is evenly distributed and the welding points are not easy to break. The sub-filter mesh 11 made of 304 stainless steel has good corrosion resistance, can be used in a variety of environments without being prone to rust or damage, and has good mechanical strength, can withstand greater pressure and load, and screen materials in large quantities. The square mesh holes are more conducive to cleaning and not easy to block. The square mesh hole structure is relatively stable and can withstand a certain amount of pressure and weight. Then wrap the periphery of the filter mesh 1 with the silica gel ring 12.

[0026] Among them, several positioning blocks 2 are respectively fixedly connected to one side of the frame of the sub-filter mesh 11. The several positioning blocks 2 are distributed in a circular array. Positioning grooves 21 are respectively opened on the other side of the sub-filter mesh 11 for matching with the several positioning blocks 2.

[0027] When stacking the sub-filter meshes 11, first place a sub-filter mesh 11 with the positioning groove 21 facing down at the bottom, and then place the second sub-filter mesh 11. When placing it, align the positioning groove 21 at the bottom of the second sub-filter mesh 11 with the positioning block 2 and put it down, so that it is easier to align during stacking and the filter mesh 1 will not move out of position due to touching during welding, which is more conducive to welding. After welding two filter meshes together, continue to stack and weld the filter meshes 1, so as to weld the four filter meshes together.

[0028] Among them, an embedding groove 3 is opened on the inner wall of the silica gel ring 12. The frame of the filter mesh 1 is located inside the embedding groove 3. The thickness of the silica gel ring 12 is greater than the thickness of multiple filter meshes 1. Placing grooves 31 are respectively opened on the opposite sides of the sub-filter mesh 11. A sealing ring 32 is arranged between the two opposite placing grooves 31. Through holes 33 for passing through the several positioning blocks 2 are opened on the sealing ring 32. Grooves 34 are respectively opened on the opposite sides of the sealing ring 32.

[0029] While filtering stacks, fetch the sealing ring 32 and place it on the bottommost filter net 1. Align the through-hole 33 of the sealing ring 32 with the positioning block 2 at the top of the sub-filter net 11 and place it, so that the sealing ring 32 falls into the placement groove 31. A sealing ring 32 should be placed between adjacent two sub-filter nets 11. The sealing ring 32 is located between two placement grooves 31 with opposite ends facing each other. During welding, press and frame the top sub-filter net 11 to make the top and bottom of the two sub-filter nets 11 closely fit together to reduce the existence of gaps. Pressing will deform the sealing ring 32 and thus fill the gaps. The groove 34 can accommodate the deformation and extension of the sealing ring 32, and thus can seal the gaps between the filter nets 1 to prevent fine debris from passing through the gaps. After the four sub-filter nets 11 are welded together, fetch the silicone ring 12 and sleeved the silicone ring 12 on the periphery of the filter net 1. When sleeving, embed the frame of the filter net 1 into the embedding groove 3 of the silicone ring 12, and the inner diameter of the silicone ring 12 is smaller than the diameter of the filter. Therefore, after the silicone ring 12 is sleeved, under the action of its elasticity, it can closely fit with the outside of the filter net 1.

[0030] The specific usage method and function of this embodiment:

[0031] During manufacturing, take four sub-filter nets 11 with a mesh number of 20 and stack them neatly together. First, place a sub-filter net 11 with the positioning groove 21 facing down at the bottommost. Fetch the sealing ring 32 and place it on the bottommost sub-filter net 11. Align the through-hole 33 of the sealing ring 32 with the positioning block 2 at the top of the sub-filter net 11 and place it, so that the sealing ring 32 falls into the placement groove 31. Then place the second sub-filter net 11. When placing it, align the positioning groove 21 at the bottom of the second sub-filter net 11 with the positioning block 2 and place it down, so that it is easier to align during stacking and the sub-filter net 11 will not move out of position due to touching during welding. The sealing ring 32 is located between two placement grooves 31 with opposite ends facing each other. Immediately press and frame the top sub-filter net 11 to make the top and bottom of the two sub-filter nets 11 closely fit together to reduce the existence of gaps. Pressing will deform the sealing ring 32 and thus fill the gaps. The groove 34 can accommodate the deformation and extension of the sealing ring 32, and thus can seal the gaps between the sub-filter nets 11 to prevent fine debris from passing through the gaps. Use the spot welding method to weld the two sub-filter nets 11 together. The number of welding points should not be less than 8, and the welding points should be kept evenly distributed in a ring shape, so as to improve the welding strength. Stack and weld according to the above method. A sealing ring 32 should be placed between adjacent two filter nets 1 until all four filter nets 1 are welded together to form the filter net 1. After the four filter nets 1 are welded together, fetch the silicone ring 12 and sleeved the silicone ring 12 on the periphery of the filter net 1. When sleeving, embed the frame of the filter net 1 into the embedding groove 3 of the silicone ring 12, and the inner diameter of the silicone ring 12 is smaller than the diameter of the filter. Therefore, after the silicone ring 12 is sleeved, under the action of its elasticity, it can closely fit with the outside of the filter net 1, thus completing the production of the filter net 1.
