Technical Field
[0001] The utility model belongs to the technical field of extrusion equipment, in particular to a wire extrusion device for a wire mesh demister mesh. Background Art
[0002] Wire mesh demisters are becoming more and more widely used in fields such as sewage treatment. After the gas-liquid mixture with foam passes through the demister, when the foam passes through the mesh of the wire mesh demister, the outer side of the foam is punctured or squeezed by the wire of the mesh. Existing wire mesh demisters are generally extruded by an extrusion device. The extrusion device currently used includes a metal wire feeding mechanism located in the front, a mixing extruder head is arranged behind the metal wire feeding mechanism, a first cooling water trough is arranged behind the mixing extruder head, and a traction wire collection mechanism with a wire collection wheel is arranged behind the first cooling water trough. Due to structural reasons, the existing extrusion device has the following defects: the surface of the wire extruded by the extrusion device is smooth, and the mesh woven with the wire has a strong permeability. When the foam passes through the mesh of the mesh, the foam passes through easily, and the defoaming effect is poor. Utility Model Content
[0003] The first technical problem to be solved by the utility model is to provide a wire extrusion device for a wire mesh demister mesh with good defoaming effect.
[0004] In order to solve the above technical problems, the technical solution adopted by the wire mesh demister of the utility model is as follows: it includes a metal wire feeding mechanism located in the front, a mixing extruder head is arranged behind the metal wire feeding mechanism, a first cooling water trough is arranged behind the mixing extruder head, a traction and wire collecting mechanism with a wire collecting wheel is arranged behind the first cooling water trough, and an indentation mechanism is arranged between the first cooling water trough and the traction and wire collecting mechanism, the indentation mechanism includes a heating box close to one side of the first cooling water trough and an indentation wheel frame located behind the heating box, a wire channel is arranged on the heating box, and two relative indentation wheels are arranged on the indentation wheel frame, the indentation wheel is connected to the wire collecting wheel of the traction and wire collecting mechanism through a transmission chain, and a convex pattern is arranged on the indentation wheel, the height of the convex pattern is less than half the thickness of the outer layer of the non-metallic material, and the distance between the outer surfaces of the two indentation wheels is equal to the outer diameter of the outer layer of the non-metallic material.
[0005] The technical features of its accessories are:
[0006] A second cooling water tank is provided between the creasing wheel and the wire drawing and collecting mechanism.
[0007] Compared with the prior art, the wire extrusion device for wire mesh demister mesh provided by the utility model has the following advantages:
[0008] Firstly, it includes a wire feeding mechanism located in the front, a mixing extruder head is arranged behind the wire feeding mechanism, a first cooling water trough is arranged behind the mixing extruder head, a traction and wire collecting mechanism with a wire collecting wheel is arranged behind the first cooling water trough, a creasing mechanism is arranged between the first cooling water trough and the traction and wire collecting mechanism, the creasing mechanism includes a heating box close to the first cooling water trough and a creasing wheel frame located behind the heating box, a wire channel is arranged on the heating box, two relative creasing wheels are arranged on the creasing wheel frame, the creasing wheel is connected to the wire collecting wheel of the traction and wire collecting mechanism through a transmission chain, and convex patterns are arranged on the creasing wheel, the height of the convex patterns is less than half of the thickness of the outer layer of the non-metallic material, and the two creasing wheels The distance between the outer surfaces is equal to the outer diameter of the outer layer of the non-metallic material. In this way, the metal wire core wrapped with the outer layer of the non-metallic material extruded from the extruder is first cooled in the first cooling water tank, and the outer layer of the non-metallic material is attached to the outside of the metal wire core. When heated by the heating box, the outer layer of the non-metallic material on the surface is softened, while the outer layer of the non-metallic material attached to the surface of the metal wire core hardly changes. When the outer layer of the non-metallic material with the softened surface passes through the creasing wheel, a pattern is formed on the surface of the outer layer of the non-metallic material. The creasing wheel is connected to the wire collecting wheel of the traction wire collecting mechanism through a transmission chain to rotate synchronously. When the wire moves forward, the wire and the creasing wheel do not have relative displacement, and the outer layer of the non-metallic material will not be damaged. The wire is only radially extruded to form a concave and convex pattern on the surface of the outer layer of the non-metallic material. If cooled in front of the first cooling water trough, although the outer surface of the non-metallic material has hardened and shaped, the outer layer of the non-metallic material attached to the surface of the metal wire inner core is still too hot, just like crispy ice cream, the outermost layer of solidified non-metallic material is easy to fall off due to extrusion, resulting in uneven outer layer of non-metallic material on the outer layer of the metal wire inner core, the metal wire inner core is easily exposed, and the corrosion resistance is greatly reduced; secondly, since a second cooling water trough is arranged between the indentation wheel and the traction wire collection mechanism, the shaping effect of the silk thread is better after being cooled in the second cooling water trough after indentation.

[0014] The structure and use principle of the wire extrusion device for a wire mesh demister mesh of the utility model are further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0015] like Figure 1 , Figure 2 and Figure 3 As shown, the wire extrusion device for the wire mesh demister mesh of the utility model comprises a wire feeding mechanism 1 located in the front, a mixing extruder head 2 is arranged behind the wire feeding mechanism 1, a first cooling water trough 3 is arranged behind the mixing extruder head 2, a traction wire collecting mechanism 5 with a wire collecting wheel 4 is arranged behind the first cooling water trough 3, and an indentation mechanism 6 is arranged between the first cooling water trough 3 and the traction wire collecting mechanism 5. The indentation mechanism 6 comprises a heating box 61 close to one side of the first cooling water trough and an indentation wheel frame 62 located behind the heating box 61, a wire channel 63 is arranged on the heating box 61, and two relative indentation wheels 64 are arranged on the indentation wheel frame 62, and the indentation wheel 64 is connected to the power of the synchronous rotation of the wire collecting wheel 4 of the traction wire collecting mechanism 5 through a transmission chain or other transmission mechanism. Of course, the indentation wheel 64 can also be connected to the power of an independent motor alone, and at this time, the motor rotates synchronously with the wire collecting wheel. The creasing wheel 64 is provided with a convex pattern 65, the height of which is less than half the thickness of the outer layer of the non-metallic material, and the distance between the outer surfaces of the two creasing wheels 64 is equal to the outer diameter of the outer layer of the non-metallic material. In this way, the inner core of the metal wire wrapped with the outer layer of the non-metallic material extruded from the extruder is first cooled by the first cooling water tank 3, and the outer layer of the non-metallic material is attached to the outer side of the inner core of the metal wire. When heated by the heating box 61, the outer layer of the non-metallic material on the surface is softened, while the outer layer of the non-metallic material attached to the surface of the inner core of the metal wire is almost unchanged. When the outer layer of the non-metallic material whose surface is softened passes through the creasing wheel, a pattern is formed on the surface of the outer layer of the non-metallic material. The creasing wheel 64 is connected to the power of the synchronous rotation of the wire collecting wheel of the traction wire collecting mechanism through a transmission chain. When the wire moves forward, the wire and the creasing wheel 64 do not move relative to each other, and the outer layer of the non-metallic material will not be damaged. The wire is only radially extruded to form a concave-convex pattern on the surface of the outer layer of the non-metallic material. If cooled in front of the first cooling water trough, although the outer surface of the non-metallic material has hardened and fixed, the outer layer of the non-metallic material attached to the surface of the metal wire inner core is still too hot, just like crispy ice cream. The outermost layer of solidified non-metallic material is easy to fall off due to extrusion, resulting in uneven outer layer of non-metallic material on the outer layer of the metal wire inner core, and the metal wire inner core is easily exposed to the outside, and the corrosion resistance is greatly reduced.
[0016] like Figure 4 and Figure 5As shown, a second cooling water trough 7 is provided between the creasing wheel 64 and the traction wire collecting mechanism 5. After the creasing wire is cooled by the second cooling water trough 7, the shaping effect is better.
[0017] The protection scope of the present invention is not limited to the above-mentioned embodiments. As long as the structure is the same or similar to the structure of the wire extrusion device for the wire mesh demister mesh of the present invention, it falls within the protection scope of the present invention.
