Stainless steel wave plate combined honeycomb inclined tube for water treatment and combined welding device

[0034] Example 1: see figure 1 , 2 , 3, 4, forming a stainless steel trapezoidal wave plate 1 with short planes on both sides and a thickness of 0.31mm, forming a stainless steel honeycomb inclined tube 2 through adjacent combination and welding. The oblique tube is 1000mm long, 940mm wide, stacked 250 to 1000mm high, and honeycomb hole diameter 35mm.

[0035] The above honeycomb inclined pipe connection welding device includes a vertical frame 3, the upper cross beam 3.1 has a spot welding car 5 that moves forward and backward, and the spot welding car 5 is driven by the upper motor 9 to drive the screw 9.1 forward and reverse to drive the screw rod Sim 9.2, which is matched and connected with the spot welding car, moves forward and backward, thereby driving the spot welding car to move forward and backward. There are multiple spot welding heads 5.1 with the same number of welding edges arranged on the spot welding car. Each spot welding head is driven by hydraulic pressure or cylinder 5.2, which can move up and down at the same time or separately to connect the wave plate according to the required spot welding. There is a hexagonal fixed electrode rod 6 with the same shape and number as the honeycomb hole under the spot welding head, and the length is greater than the length of the honeycomb. One end of the electrode rod 6 is fixed on the frame, and the other end is suspended (to facilitate the exit of the welding honeycomb tube). 7 The supporting roller that drives the rotation 8 supports the dangling end of the electrode rod during welding, that is, the electrode rod is turned under the electrode rod during welding to support the electrode rod, and after welding, it turns to give way to the passage to facilitate the exit of the welding honeycomb tube. There is a carriage 4 that can move forwards and backwards under the frame. The carriage 4 can move forwards and backwards as well as up and down. The lifting motor 4.3 drives the screw 4.2 to rotate to realize the up and down movement of the carriage, supporting the welded honeycomb body There are four positioning guide rods 4.1 for positioning up and down on the pallet. The lifting distance of the pallet can accommodate the height of the welded honeycomb stack from 250 to 1000mm.

[0036] Assemble the honeycomb inclined tube, first place a piece of formed stainless steel wave plate 1 above and below the electrode rod. The wave plate under the electrode rod is supported by the support plate of the movable carrier 4, and the electrode rod roller 8 is rotated to the support below the electrode rod. Electrode rod. Move the spot welding cart 5 to the farthest welding position of the spot welding, and press down each spot welding head 5.1 at the same time to form a spot welding between the two electrodes. Back a distance to continue the spot welding, and then back to a spot welding position (more than three spot welding) ). After the two pieces of spot welding are connected and fixed, move the carrier, disconnect the wave tube from the electrode rod, descend a distance, move the carrier back, and place a trapezoidal wave plate on the electrode rod. Like the previous spot welding, the cycle is repeated until the stack reaches the required thickness (for example, 250 to 1000 mm). All action processes are controlled by the program.

[0037] Example 2: see Figure 5-7 , Composed of honeycomb oblique pipes that overlap adjacent wave plates are fixed by tongues. Three or more elongated holes 1.11 are punched in one wave plate 1.1 wave trough, and the corresponding area of ​​the other wave plate 1.2 is punched with convex bends. The tongue piece 1.21, when combined and fixed, insert the punched protruding bent piece 1.21 into the elongated hole 1.11 and pull it down even if the two are plugged and fixed. Combine the pieces to the required thickness to obtain the stainless steel honeycomb inclined pipe 2.
