Description

Technical Field

[0001] The invention relates to a structured packing welding device, belonging to the technical field of structured packing welding equipment. Background Art

[0002] Structured packing is a highly efficient gas-liquid contact element, widely used in distillation towers, absorption towers, reaction towers and other equipment in the chemical, petroleum, environmental protection and other industries. Corrugated plate structured packing is a commonly used type in industrial production. This type of packing is made of multiple layers of stainless steel corrugated plates stacked and welded, with a regular channel structure, which can significantly increase the gas-liquid contact area and mass transfer efficiency.

[0003] At present, the main process flow of corrugated plate structured packing is as follows: the stainless steel strip is stamped to form a corrugated strip, and then the corrugated strip is cut to form the corrugated plate required for the production of structured packing. Finally, multiple corrugated plates are manually stacked up front and back and sent to a resistance welding machine for welding.

[0004] The above-mentioned corrugated plate structured packing production process has the following disadvantages:

[0005] 1. Before welding, the corrugated plates need to be stacked manually one by one, with the positive and negative sides interlaced. The stacking efficiency is low, the labor intensity is high, and the edges of the corrugated plates are sharp, which can easily cause harm to the operators.

[0006] 2. When welding the corrugated plate, the existing welding machine has a single welding station. After the single set of electrodes of the welding machine is pressed down, it can only randomly weld several contact points of the entire corrugated plate in a large area at one time, and cannot involve specific positioned welding points, which can easily cause local desoldering of the structured filler, and the overall welding strength of the structured filler cannot be guaranteed.

[0085] like Figure 1-Figure 17As shown, this embodiment is implemented through the following technical solutions: a welding silo 2 is provided on the indexing table 1, and the welding silo 2 can rotate with the indexing table 1, a positioning welding tower 4 is provided on the indexing table 1, and the movable part of the positioning welding tower 4 can be inserted into the welding silo 2 to weld the filler, and a flip module 3 for transferring the filler is provided on the side of the positioning welding tower 4, and the flip module 3 is placed above the welding silo 2.

[0086] The flip module 3 includes: a lifting box 301 connected to the side of the positioning welding tower 4, the lifting box 301 is connected to the flip box 305 through a lifting component; the flip box 305 is connected to the flip slide 313 through a rotating component.

[0087] A telescopic motor 311 is arranged on the side of the flip slide 313, and the telescopic motor 311 is coaxially connected with a transverse screw 312. The transverse screw 312 drives the clamping box 315 to move on the flip slide 313 through the transverse slider 320; a plurality of clamping strips 317 and a clamping block 316 are arranged inside the clamping box 315, and the clamping block 316 elastically clamps the clamping strip 317. One side of the clamping strip 317 passes through a box plate on one side of the clamping box 315. A stepped push rod 318 is rotatably arranged inside the clamping box 315, and the working surface of the stepped push rod 318 abuts against one side of the clamping strip 317. The stepped push rod 318 can rotate to drive the clamping strip 317 to move in sequence, and the stepped push rod 318 is coaxially connected with a clamping motor 314 arranged on the clamping box 315.

[0088] In this embodiment, the number of transverse screws 312 is two, and the threads of the two transverse screws 312 have opposite rotation directions. The telescopic motor 311 is a double-axis stepping motor. The telescopic motor 311 drives the two transverse screws 312 to rotate, thereby driving the two clamping boxes 315 to shrink inward or expand outward at the same time, that is, the distance between the two clamping boxes 315 is reduced or increased at the same time; the distance between the clamping boxes 315 is adjusted according to the width size of the corrugated plate of different specifications; after the distance between the clamping boxes 315 is determined, the corrugated plate 501 is clamped by the stepped top rod 318, the clamping strip 317 and its associated components.

[0089] Specifically, the lifting assembly includes: a lifting motor 304 arranged inside the lifting box 301, the lifting motor 304 is coaxially connected with a lifting screw 303, the lifting screw 303 is provided with a lifting slider 302 matching therewith, and one end of the lifting slider 302 is connected to the side of the flip box 305.

[0090] The rotating assembly includes: a flip motor 306 arranged inside the flip box 305, the flip motor 306 is coaxially connected with a rotating shaft 307, a bearing 308 is sleeved on the rotating shaft 307, the bearing 308 is clamped on the flip box cover 309, one end of the rotating shaft 307 is connected to a adapter 310; the adapter 310 is fixedly connected to the side of the flip slide 313.

[0091] A clamping box cover 319 is provided on one side of the clamping box 315 ; a pressing seat 3152 is provided on the inner wall of the clamping box 315 ; a movable groove 3151 is opened on one side of the box plate of the clamping box 315 ; and a clamping strip 317 is inserted into the movable groove 3151 .

[0092] The pressing block 316 includes: a pressing plate 3163 , on which a seat cover 3161 and a fixing block 3162 are respectively provided, and the fixing block 3162 is matched and arranged in the pressing seat 3152 ; a pressing spring 3164 is arranged in the seat cover 3161 .

[0093] The clamping strip 317 includes: a support plate 3171, a baffle plate 3173 is provided on the side of the support plate 3171, a clamping pile 3174 is provided on the side of the baffle plate 3173, one end of the clamping pile 3174 is in contact with the clamping spring 3164; an open ring 3172 is protruding from the baffle plate 3173; and a step surface 3175 is provided on the side of the support plate 3171 away from the baffle plate 3173.

[0094] A plurality of top blocks 3181 are provided on the stepped top rod 318 , and the side surfaces of the top blocks 3181 abut against the side surfaces of the open ring 3172 .

[0095] In this embodiment, four top blocks 3181 are arranged on the step top rod 318, and the number of corresponding clamping strips 317 and movable grooves 3151 is also four. Fig.11 As shown; the top block 3181 is in the shape of a flat block with an irregular outer ring shape, the outer ring surface of the top block 3181 is smooth and continuous, the top block 3181 is staggered on the stepped top rod 318, and the radius from the outer ring surface of the top block 3181 to the rotation center of the stepped top rod 318 changes continuously.

[0096] When the stepped push rod 318 rotates, the outer side surface of the push block 3181 presses against the inner side of the open ring 3172, and the rotation of the push block 3181 drives the clamping strip 317 to move in the movable groove 3151. When the maximum radius of the push block 3181 presses against the open ring 3172, the step surface 3175 of the clamping strip 317 is completely retracted into the movable groove 3151.

[0097] When the abutment between the top block 3181 and the open ring 3172 transitions from the maximum radius of the top block 3181 to the minimum radius, the step surface 3175 of the clamping strip 317 gradually protrudes to the outer side of the movable groove 3151. In this process, there is a state in which only the bottom plane of the step surface 3175 protrudes out of the movable groove 3151. In this state, the step surfaces 3175 at the same horizontal position on the clamping boxes 315 on both sides form cross arms correspondingly, and the corrugated plate 501 is placed on the cross arms of the two step surfaces 3175. At this time, the corrugated plate 501 is placed on the flip module 3. Further, the top block 3181 continues to rotate, and the clamping strip 317 continues to protrude from the movable groove 3151 under the action of the compression spring 3164. The corrugated plate 501 is clamped by the side surfaces of the step surfaces 3175 on both sides. At this time, the corrugated plate 501 is clamped on the flip module 3.

[0098] When the top block 3181 at the minimum radius abuts against the open ring 3172 , the clamping strip 317 reaches the maximum distance protruding from the movable groove 3151 , and at this time, the step surface 3175 completely protrudes from the movable groove 3151 .

[0099] The top blocks 3181 are arranged in an offset manner on the step top rod 318. When the flip module 3 is loaded with the corrugated plate 501, the step top rod 318 rotates forward by a certain angle, and different top blocks 3181 drive the clamping strips 317 at the corresponding positions to shrink into the movable groove 3151 from top to bottom in turn, thereby making room for the corrugated plate 501 placed on the lower layer. The first corrugated plate 501 is placed on the step surface 3175 of the first layer at the bottom, and then the step top rod 318 continues to rotate forward by a certain angle, completing the placement and clamping of the upper corrugated plate 501 in turn; the step top rod 318 stops after rotating at a fixed angle, and the rotating assembly drives the clamping box 315 to flip 180°; at this time, the flip module 3 completes the flipping of the corrugated plate 501.

[0100] After the corrugated plate 501 is turned over, the lifting assembly drives the clamping box 315 downward to approach the welding material bin 2, and then the step top rod 318 rotates in the opposite direction by a certain angle, and the clamping strip 317 on the first layer above before turning over first shrinks into the movable groove 3151, and the corresponding corrugated plate 501 on the first layer above before turning over first falls into the welding material bin 2, and the corrugated plates 501 arranged subsequently fall in turn, and the indexing table 1 drives different welding material bins 2 to rotate to the bottom of the turning module 3, and the turned corrugated plates 501 fall into the corresponding welding material bin 2 in turn. After the corrugated plate 501 is unloaded, the lifting assembly drives the clamping box 315 to move upward, and then the turning module 3 performs the next working cycle.
