Description

Technical Field

[0001] The invention relates to the technical field of welding tooling, and more specifically to a cathode wire burr welding device based on bionics. Background Art

[0002] The cathode wire types used in electrostatic precipitators include RS barbed wire, fishbone wire, sawtooth wire, etc. A large number of literature studies have shown that the corona inception voltage and discharge capacity of these cathode wires are different; the optimization research of cathode wires is mainly based on the above inherent forms and is optimized locally (for example: tip size, same-pole spacing, barb geometric size, etc.). These optimization results only reduce the corona inception voltage of the cathode wire and improve the discharge capacity to a certain extent, but do not fundamentally solve or optimize the problem of uniform distribution of charge in the dust removal space, so cost reduction and efficiency improvement are not obvious.

[0003] Based on the above background, Patent 201810675098.9 proposes a cathode wire structure, discharge system and method based on bionics. The electric field strength formed by it makes the electric field driving force strong after the smoke is charged. The thorn discharge tip increases the uniformity of the charge distribution in space, so that the smoke in the space can be better charged, and the dust removal efficiency per unit length is greatly improved. By reducing the length of the cathode wire, the dust collector body can be "slimmed down", reducing the manufacturing cost of the electrostatic precipitator. The application of this patent has important economic and social benefits for solving the problem of achieving ultra-low emissions of flue gas and smoke after wet desulfurization. However, how to apply this cathode wire structure based on bionics to engineering practice is crucial.

[0004] In its specific engineering application, taking a single 600MW unit as an example, the number of cathode wires reaches more than 4,000 and the number of thorns is nearly 400,000. The thorn base is cylindrical, and its discharge tip diverges around the circumference of the base. Each tip presents an angular angle, which is reflected in its different spatial position. Its overall appearance structure is similar to petals or ferns. The thorns are arranged in groups of two, and the base is symmetrical along the center of the steel pipe. The spacing between each group is 100 mm, and they are arranged at 90 degrees along the circumference. The base and the steel pipe are fixed by spot welding. Traditional welding equipment cannot complete the processing of this special workpiece, and it is difficult to achieve high-precision mass production. Summary of the invention

[0042] The present invention will be further described below in conjunction with the accompanying drawings.

[0043] Figure 1-Figure 4 A bionics-based cathode wire thorn welding device according to the present application is shown. Figure 1 is a structural schematic diagram of the welding device in a first position, Figure 2 for Figure 1 Side view of Figure 3 is a structural schematic diagram of the welding device in the second orientation, Figure 4 for Figure 3 Side view of.

[0044] refer to Figure 1-Figure 4The cathode wire thorn welding device based on bionics comprises: a base 1, a flip assembly 2 and a mounting assembly 3. The flip assembly 2 is arranged on the base 1 and can be flipped relative to the base 1; the mounting assembly 3 is connected to the flip assembly 2 and is used to install the cathode wire thorn 10, and can flip the cathode wire thorn 10 to a position suitable for welding (i.e., a second position) driven by the flip assembly 2, i.e., the mounting assembly 3 is connected to the flip assembly 2 and is used to install the cathode wire thorn 10. Figure 3 -Attached Figure 4 Position shown.

[0045] Specifically, Figure 1 As shown, the turning assembly 2 includes a support shaft 21 arranged on the base 1 and a turntable 22 hinged to the support shaft 21 . The turntable 22 can turn around the position where the support shaft 21 and the turntable 22 are hinged.

[0046] The mounting assembly 3 includes a plurality of brackets 31 relatively arranged on the turntable 22, specifically, as Figure 5-8 As shown, each set of brackets 31 includes a bottom plate 311 and side plates 312 arranged on both sides of the bottom plate 311. The corresponding positions of the side plates 312 are provided with grooves 313 for placing rods 314. The rods 314 are accommodated in the grooves 313 and can rotate in the grooves 313. The grooves 313 can be U-shaped grooves or grooves of other shapes. The bottom plate 311 is provided with two clamps 315 for fixing the cathode wire thorns 10. The two clamps 315 are arranged in parallel and the rods 314 are allowed to pass through between the two clamps 315. The clamps 315 can be U-shaped elastic clamps. Preferably, the length of each bracket 31 is equal to the distance between the adjacent brackets 31.

[0047] like Figure 3 As shown, the welding device according to the present application also includes a positioning assembly 4, which is arranged at the end of the turntable 22, and the positioning assembly 4 includes a first positioning assembly 41 and a second positioning assembly 42 for positioning the rod 314 in the first direction and the second direction respectively, and the first direction and the second direction are perpendicular to each other.

[0048] Specifically, Fig. 9As shown, the first positioning assembly 41 or the second positioning assembly 42 includes a positioning column 401, a rotating shaft 402 and a connecting member 403, wherein the rotating shaft 402 is fixed to the end of the turntable 22; the first end of the connecting member 403 is sleeved on the rotating shaft 402, and the second end is connected to the positioning column 401. When the first end of the connecting member 403 rotates around the rotating shaft 402, the positioning column 401 connected to the second end can be driven to rotate, so that the positioning column 401 fixes the rod 314 to the end of the turntable 22 to prevent the rod 314 from rotating in the groove 313. Obviously, at the end of the turntable 22, another bracket is provided to support the positioning assembly 4. Preferably, the positioning assembly also includes a handle 405, which is connected to the connecting member 403, so that rotating the handle 405 can drive the first end of the connecting member 403 to rotate around the rotating shaft 402, thereby rotating the positioning column 401 connected to the second end of the connecting member 403, and pressing on the end of the rod 314 to fix the rod 314.

[0049] like Fig.10 As shown, taking the first positioning component 41 as an example, when the clamping rod 314 needs to be clamped, hold the handle 405 and rotate it counterclockwise, the handle 405 drives the positioning column 401 to rotate counterclockwise around the rotating shaft 402, when the handle 405 rotates counterclockwise to a certain angle, the bottom of the positioning column 401 can be buckled on the rod 314, thereby realizing the function of fixing the rod 314.

[0050] The working principle of the second positioning component 42 is similar to that of the first positioning component. When the clamping rod 314 needs to be clamped, hold the handle 405 and rotate it clockwise. The handle 405 drives the positioning column 401 to rotate clockwise around the rotating shaft 402. When the handle 405 rotates clockwise at a certain angle, the bottom of the positioning column 401 can be buckled on the rod 314, thereby realizing the function of fixing the rod 314.

[0051] Preferably, a positioning piece 404 is provided at the bottom of the positioning column 401. A stainless steel plate is welded at the bottom of the positioning column 401 to compress and flatten the end of the rod.

[0052] like Figure 1-Figure 4 As shown, the welding device according to the present application further includes a moving assembly 5 for driving the base 1 to move, and the moving assembly 5 includes a wheel 51 arranged on the lower surface of the base 1 and a track 52 for the wheel 51 to rotate on. Figure 1-Figure 4 As shown, the wheel 51 is a V-groove wheel, and the track 52 matches the V-groove wheel. The base 1 can move on the track 52 driven by the wheel 51.

[0053] A method for welding using the above welding device is described in detail below:

[0054] Step 1: Turn the turntable 22 to Figure 1 and Figure 2In the orientation shown, in this orientation, the U-shaped grooves 313 of the bracket 31 are all facing upward, and the rod 314 (the rod 314 can be a steel pipe, one of the ends of the steel pipe is configured to be flat, so as to facilitate the positioning of the positioning component 4. The flat end is a structural feature of the cathode line itself, and the positioning component 4 is made according to its structural feature, not deliberately flattened due to process requirements. is placed in the U-shaped groove 313. At this time, the steel pipe 314 is accommodated between two relatively arranged clamps 315. Then, the positioning component 4 at the end of the turntable 22 is locked to prevent the steel pipe 314 from rotating. At this time, the first positioning component 41 is locked, that is, when the positioning piece 404 contacts the steel pipe 314, the positioning piece 404 is parallel to the flat end of the steel pipe 314.

[0055] Step 2: Place the cathode wire thorn 10 into the fixture 315 manually or by a mechanical arm gripper, wherein the structure of the cathode wire thorn 10 is as follows: Fig.10 As shown, the placement direction of the cathode wire barbs 10 is: the base 102 is vertically inserted into the fixture 315, and the tip 101 is perpendicular to the side of the fixture 315 and faces outward. After placement, two cathode wire barbs 10 are installed in a pair of fixtures 315, and the bases of the two cathode wire barbs 10 are arranged adjacent to each other. Since the bases of the cathode wire barbs 10 are provided with notches, the notches are configured in a semicircular shape. After installation, the notches on the bases of the two oppositely arranged cathode wire barbs 10 correspond to each other and form a circle that matches the diameter of the steel pipe 314.

[0056] Step 3: After the cathode wire barbs 10 are placed, the turntable 22 is turned over manually or driven by a motor to Figure 3 and Figure 4 Then, the cathode wire burr 10 is welded, and the welding method can be manual welding or offline programming welding of a welding robot. The welding point position is as shown in FIG. Figure 8 As shown at point M in the middle, each welding point can simultaneously weld and fix the bases of the two thorns and the steel pipe. Figure 8 The welding points shown in are two points on the front side of the cathode wire thorn 10. It should be noted that there are also welding points on the back side of the cathode wire thorn 10. The welding points on the back side can be set at a position corresponding to the front side, or at a position on the back side corresponding to the middle position of the two points on the front side. The welding points on the back side can be one point or two points, as long as they are symmetrical with the welding points on the front side about the intersection of the central axis of the two connected thorns and the center line of the steel pipe. That is, the total number of welding points can be two points on the front side and two points on the back side; or one point on the front side and one symmetrical point on the back side. For details, see Figure 8 .

[0057] After all the cathode wire burrs 10 are welded, the turntable 22 is turned back Figure 1 and Figure 2 The welded cathode wire thorn 10 is then demoulded, that is, the mounting assembly 3 is separated from the cathode wire thorn 10.

[0058] Step 4: After the steel tube 314 is disengaged, rotate it 90 degrees, and then move the steel tube 314 forward or backward for a certain distance, preferably 100 mm. It can be understood that the distance varies for different products, and the size of this product is 100 mm. The actual moving distance is Figure 3 After the steel pipe 314 has been moved a certain distance, it is put back into the U-shaped groove 313 of the bracket 31, and then the positioning assembly 4 is locked. Since the steel pipe 314 is turned over 90 degrees, the flat structure at its end is also turned over 90 degrees accordingly. Therefore, at this time, the second positioning device 402 is locked.

[0059] Step 5: Repeat the actions of steps 2 to 4 to complete the welding of the cathode wire thorn 10.

[0060] In summary, the present application has the following advantages: the welding device of the present application is suitable for mass processing of cathode wire thorns based on bionics, the equipment is simple, the operation is convenient, and it is easy to realize automated production. The welding device according to the present application is applied to the processing and production of cathode wire thorns based on bionics, and the tip of the cathode wire thorn produced thereby increases the uniformity of the charge distribution in space, so that the smoke in the space can be better charged, the electric field driving force of the smoke after being charged is strong, and the dust removal efficiency is greatly improved.
