[0010] Further, a rectangular block is fixedly installed at the bottom of the welding box. An air inlet cavity is formed in the rectangular block. The ends of the two U-shaped pipes communicate with the air inlet cavity. A ventilation cavity is formed in the rectangular block. The air inlet cavity is the same as the ventilation cavity. The end of the air suction pipe communicates with the ventilation cavity.

[0011] Further, a drainage mechanism is arranged on the rotating shaft. The drainage mechanism includes a rectangular groove formed in the rotating shaft. A threaded plate is slidably sleeved on the rectangular groove. Two U-shaped frames are fixedly installed on the right side of the threaded plate. Rotating rollers are respectively rotatably installed on the two U-shaped frames.

[0012] Further, a reciprocating thread is formed on the inner wall of the cylinder. The threaded plate meshes with the reciprocating thread. A drainage inclined groove is formed on the inner wall of the cylinder.

[0013] Further, a circulating mechanism is arranged in the welding box. The circulating mechanism includes a hydraulic cylinder fixedly installed on the left inner wall of the spraying cavity. A strip-shaped block is fixedly installed at the right end of the hydraulic cylinder. The strip-shaped block is adapted to the spraying cavity. A plurality of spraying holes are formed in the spraying cavity. All the plurality of spraying holes communicate with the ventilation cavity.

[0014] Further, the circulating mechanism further includes two circulating components. The circulating component includes a T-shaped groove formed in the strip-shaped block. A rectangular plate is slidably installed in the T-shaped groove. The left side of the rectangular plate extends outside the T-shaped groove.

[0017] Further, a T-shaped plate is fixedly installed on the right side of the triangular belt hole plate. The right end of the T-shaped plate slidably extends outside the rectangular block. The right end of the T-shaped plate is an isosceles inclined surface. A collecting box contact plate is fixedly installed on the rotating shaft. Collecting boxes are respectively slidably installed on the front and back of the welding box. Both the two collecting boxes communicate with the ventilation cavity.

[0018] Further, a method for an assembled building material steel bar welding device is as follows:

[0019] S1: Reduce air humidity: When the gas passes through the cylinder, the moisture in the gas will pass through the water-absorbing sponge, and the water-absorbing sponge will filter out the moisture in the air, thereby reducing the air humidity blown into the welding box. After the air blows into the welding box from the air guide inclined cover, the gas above the welding box will be discharged from the top of the welding box under the push of the blown gas, making the gas in the welding box in a low-humidity state, effectively avoiding that a large amount of humidity in the air causes more hydrogen elements to be absorbed in the weld. Hydrogen accumulates in the weld metal, which will form a hydrogen embrittlement phenomenon, significantly reducing the strength, especially the toughness, of the weld;

[0020] S2: Extrude moisture: Since the threaded plate is constantly rotating, the corresponding roller will also rotate at the same time. The roller will rotate and squeeze the moisture on the water-absorbing sponge. Under the reciprocating action of the reciprocating thread, the roller will intermittently rotate and squeeze the water-absorbing sponge so that the water on the water-absorbing sponge can be continuously extruded, avoiding excessive saturation of water on the water-absorbing sponge and affecting the water absorption of the water-absorbing sponge. The extruded water will be discharged out of the device through the drainage chute;

[0021] S3: Recirculating spray: The water will push the rectangular plate to move towards the hydraulic cylinder. At this time, the telescopic spring undergoes a tensile deformation. When the L-shaped groove on the rectangular plate leaves the outside of the strip block, the water will drain from the L-shaped groove to the left side of the strip block, preparing for the next cycle of spraying smoke and dust. During the continuous reciprocating movement of the hydraulic cylinder, the spray holes will continuously spray smoke and dust, achieving the effect of continuously filtering impurity particles;

[0022] S4: Separate smoke and dust impurities: The triangular belt orifice plate will return under the elastic force of the limit spring. During the continuous rotation of the rotating shaft, the triangular belt orifice plate will continuously reciprocate and shake. The shaking will cause the impurity particles staying on the surface of the triangular belt orifice plate to slide down to the lower part of the two inclined surfaces of the triangular belt orifice plate. The sliding impurity particles will enter the two collection boxes for collection. Correspondingly, the water will enter the spray cavity through the holes on the triangular belt orifice plate. Continuous shaking can prevent the holes on the triangular belt orifice plate from being blocked, thus affecting the effect of filtering smoke and dust impurities.

[0023] The present invention has the following beneficial effects:

[0024] (1) An assembly - type building material steel bar welding device of the present invention. When in use, the steel bar is placed into the welding box, and then the driving motor is started. The driving motor drives the rotating shaft to rotate, and the rotating shaft drives several heat - dissipating fan blades to rotate. The rotation of the heat - dissipating fan blades generates a suction force. The suction force extracts the gas in the welding box through the dust - suction hood, U - shaped pipe, air - inlet cavity, ventilation cavity and air - suction pipe, and discharges the gas in the welding box from the air - blowing pipe and the air - guiding inclined cover. When the gas passes through the cylinder, the moisture in the gas will pass through the water - absorbing sponge, and the water - absorbing sponge will filter out the moisture in the air, thereby reducing the humidity of the air blown into the welding box. After the air is blown into the welding box from the air - guiding inclined cover, the gas above the welding box will be pushed by the blown - in gas and discharged from the top of the welding box, making the gas in the welding box in a low - humidity state. This effectively avoids that due to high humidity in the air, more hydrogen elements will be absorbed in the weld. The hydrogen accumulates in the weld metal and will form a hydrogen embrittlement phenomenon, significantly reducing the strength, especially the toughness of the weld;

[0025] (2) An assembly - type building material steel bar welding device of the present invention. During the rotation of the rotating shaft, the threaded plate will be driven to rotate under the action of the rectangular groove. Since the threaded plate is adapted to the reciprocating thread on the inner wall of the cylinder, when the threaded plate rotates, it will rotate and move closer to the welding box. The threaded plate will drive the U - shaped frame to move synchronously, and the corresponding reciprocating thread will move synchronously. When the roller contacts the water - absorbing sponge, it will squeeze the water - absorbing sponge during the approaching process, so that the water absorbed by the water - absorbing sponge is discharged outside the water - absorbing sponge. Since the threaded plate is constantly rotating, the corresponding roller will also rotate simultaneously. The roller will rotate and squeeze the water on the water - absorbing sponge. Under the reciprocating action of the reciprocating thread, the roller will intermittently rotate and squeeze the water - absorbing sponge so that the water on the water - absorbing sponge can be continuously extruded, avoiding the water - absorbing sponge being saturated with too much water and affecting the water - absorption of the water - absorbing sponge. The extruded water will be discharged outside the device through the drainage inclined groove;

[0026] (3) An assembly - type building material steel bar welding device of the present invention. During welding, the dust - suction hood will suck the gas containing soot into the ventilation cavity, and then the hydraulic cylinder is started. The hydraulic cylinder drives the strip - shaped block to move towards the direction close to the hydraulic cylinder. The strip - shaped block will squeeze the water in the spray cavity, and the water will be discharged into the ventilation cavity from several spray holes. The water droplets discharged from the spray holes will wash the soot passing through the ventilation cavity. The water droplets will carry the harmful substances and impurities in the soot to the triangular belt orifice plate, realizing the filtration of harmful soot and avoiding the soot particles from returning to the welding box again and causing harm to people. When the hydraulic cylinder drives the strip - shaped block to move away from the hydraulic cylinder, the water will enter the T - shaped groove through the water - inlet groove. The water will push the rectangular plate to move towards the direction close to the hydraulic cylinder. At this time, the telescopic spring undergoes a tensile deformation. When the L - shaped groove on the rectangular plate leaves outside the strip - shaped block, the water will be discharged from the L - shaped groove to the left side of the strip - shaped block, preparing for the next cycle of spraying soot. During the continuous reciprocating movement of the hydraulic cylinder, the spray holes will continuously spray the soot, realizing the effect of continuously filtering impurity particles;

[0027] (4) In the process of the rotation of the rotating shaft of the prefabricated building material steel bar welding device of the present invention, the contact plate will be driven to rotate. The contact plate will come into contact with the T-shaped plate, and the T-shaped plate will drive the triangular belt orifice plate to move towards the driving motor. At this time, the limiting spring will undergo a compressive deformation. After the contact plate leaves the T-shaped plate, the triangular belt orifice plate will return under the elastic force of the limiting spring. During the continuous rotation of the rotating shaft, the triangular belt orifice plate will continuously reciprocate and shake. The shaking will cause the impurity particles staying on the surface of the triangular belt orifice plate to slide down to the lower parts of the two inclined surfaces of the triangular belt orifice plate, and the sliding impurity particles will enter the two collection boxes for collection. Correspondingly, the water will enter the spraying cavity through the holes on the triangular belt orifice plate. The continuous shaking can prevent the holes on the triangular belt orifice plate from being blocked, thus affecting the effect of filtering smoke and dust impurities.

[0028] Of course, it is not necessary for any product implementing the present invention to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Please refer to Figures 1-8 As shown, the present invention is an assembled building material steel bar welding device, including a welding box 1.

[0044] The exhaust assembly includes two air blowing pipes 504 fixedly installed on the right side of the cylinder 2. Guide wind inclined covers 505 are respectively fixedly installed at the bottoms of the two air blowing pipes 504. A suction pipe 506 is fixedly installed on the left side of the cylinder 2. Dust suction covers 507 are respectively fixedly installed on the front inner wall and the back inner wall of the welding box 1. C-shaped pipes 508 are respectively fixedly installed on one side of the two dust suction covers 507 away from each other.

[0045] As Figure 3 and Figure 4 shown, a rectangular block 509 is fixedly installed at the bottom of the welding box 1. An air inlet cavity 510 is formed in the rectangular block 509. The ends of the two C-shaped pipes 508 communicate with the air inlet cavity 510. A ventilation cavity 511 is formed in the rectangular block 509. The air inlet cavity 510 communicates with the ventilation cavity 511. The end of the suction pipe 506 communicates with the ventilation cavity 511.

[0046] The heat dissipation fan blades 501 rotate to generate a suction force. The suction force extracts the gas in the welding box 1 through the dust suction covers 507, C-shaped pipes 508, air inlet cavity 510, ventilation cavity 511 and suction pipe 506, and discharges the gas in the welding box 1 from the air blowing pipes 504 and guide wind inclined covers 505.

[0047] As Figure 3 shown, a drainage mechanism 6 is arranged on the rotating shaft 4. The drainage mechanism 6 includes a rectangular groove 601 formed in the rotating shaft 4. A threaded plate 602 is slidably sleeved on the rectangular groove 601. Two C-shaped frames 603 are fixedly installed on the right side of the threaded plate 602. Rotating rollers 604 are respectively rotatably installed on the two C-shaped frames 603.

[0048] When the threaded plate 602 rotates, it will rotate and approach in the direction close to the welding box 1, and the threaded plate 602 will drive the C-shaped frames 603 to move synchronously.

[0049] As Figure 3 shown, a reciprocating thread 605 is formed on the inner wall of the cylinder 2. The threaded plate 602 meshes with the reciprocating thread 605. A drainage inclined groove 606 is formed on the inner wall of the cylinder 2.

[0050] Under the reciprocating action of the reciprocating thread 605, the rotating roller 604 will intermittently rotate and squeeze the water absorption sponge 503 so that the water on the water absorption sponge 503 can be continuously squeezed out, avoiding excessive saturation of water on the water absorption sponge 503 and affecting the water absorption of the water absorption sponge 503. The squeezed water will be discharged out of the device from the drainage inclined groove 606.

[0051] As Figure 5 and Figure 7As shown in the figure, a circulation mechanism 7 is arranged inside the welding box 1. The circulation mechanism 7 includes a hydraulic cylinder 702 fixedly installed on the left inner wall of the spraying cavity 701. The right end of the hydraulic cylinder 702 is fixedly installed with a strip-shaped block 703. The strip-shaped block 703 is adapted to the spraying cavity 701. A plurality of spraying holes 704 are formed in the spraying cavity 701, and all the plurality of spraying holes 704 communicate with the ventilation cavity 511.

[0052] During welding, the dust suction hood 507 will suck the gas containing soot into the ventilation cavity 511. Then, the hydraulic cylinder 702 is started. The hydraulic cylinder 702 drives the strip-shaped block 703 to move towards the direction close to the hydraulic cylinder 702, and the strip-shaped block 703 will squeeze the water in the spraying cavity 701.

[0053] As Figure 7 shown in the figure, the circulation mechanism 7 further includes two circulation components. The circulation component includes a T-shaped groove 705 formed in the strip-shaped block 703. A rectangular plate 706 is slidably installed in the T-shaped groove 705. The left side of the rectangular plate 706 extends outside the T-shaped groove 705. The right side of the rectangular plate 706 is fixedly installed with a telescopic spring 707, and the right end of the telescopic spring 707 is fixedly connected to the T-shaped groove 705.

[0054] The water will push the rectangular plate 706 to move towards the direction close to the hydraulic cylinder 702. At this time, the telescopic spring 707 undergoes tensile deformation.

[0055] As Figure 7 shown in the figure, L-shaped grooves 708 are respectively formed on the left and right sides of the rectangular plate 706. A plurality of water inlet grooves 709 are formed on the right side of the strip-shaped block 703, and all the plurality of water inlet grooves 709 communicate with the T-shaped groove 705.

[0056] When the L-shaped groove 708 on the rectangular plate 706 leaves outside the strip-shaped block 703, the water will be discharged from the L-shaped groove 708 to the left side of the strip-shaped block 703, preparing for the next cycle of spraying soot. During the continuous reciprocating movement of the hydraulic cylinder 702, the spraying holes 704 will continuously spray soot, achieving the effect of continuously filtering impurity particles.

[0057] As Figure 5 shown in the figure, a shaking mechanism 8 is arranged in the ventilation cavity 511. The shaking mechanism 8 includes two round rods 801 fixedly installed in the ventilation cavity 511. A triangular belt hole plate 802 is slidably sleeved on the two round rods 801. Limiting springs 803 are respectively sleeved on the two round rods 801. The left ends of the two limiting springs 803 are fixedly connected to the ventilation cavity 511, and the right ends of the two limiting springs 803 are fixedly connected to the triangular belt hole plate 802.

[0058] The V-belt orifice plate 802 will return under the elastic force of the limit spring 803. During the continuous rotation of the rotating shaft 4, the V-belt orifice plate 802 will continuously reciprocate and shake. The shaking will cause the impurity particles staying on the surface of the V-belt orifice plate 802 to slide down to the lower part of the two inclined surfaces of the V-belt orifice plate 802.

[0059] As Figure 1 and Figure 2 shown, a T-shaped plate 804 is fixedly installed on the right side of the V-belt orifice plate 802. The right end of the T-shaped plate 804 slides and extends outside the rectangular block 509. The right end of the T-shaped plate 804 is an isosceles inclined surface. A collection box contact plate 805 is fixedly installed on the rotating shaft 4. The front and back of the welding box 1 are respectively slidably installed with collection boxes 806.

[0060] During the rotation of the rotating shaft 4, the contact plate 805 will be driven to rotate. The contact plate 805 will contact the T-shaped plate 804, and the T-shaped plate 804 will drive the V-belt orifice plate 802 to move towards the direction close to the driving motor 3.

[0061] As Figure 1 - Figure 8 shown, a method for an assembled building material steel bar welding device is as follows:

[0062] S1: Reduce air humidity: When the gas passes through the cylinder 2, the moisture in the gas will pass through the water-absorbing sponge 503, and the water-absorbing sponge 503 will filter out the moisture in the air, thereby reducing the air humidity blown into the welding box 1. After the air blows into the welding box 1 from the air guiding inclined cover 505, the gas above the welding box 1 will be discharged from the top of the welding box 1 under the push of the blown gas, so that the gas in the welding box 1 is in a low humidity state, effectively avoiding that a large amount of hydrogen elements will be absorbed in the weld due to high air humidity. The hydrogen accumulates in the weld metal and will form a hydrogen embrittlement phenomenon, significantly reducing the strength, especially the toughness, of the weld.

[0063] S2: Extrude moisture: Since the threaded plate 602 is continuously rotating, the corresponding roller 604 will also rotate simultaneously. The roller 604 will rotate and squeeze the moisture on the water-absorbing sponge 503. Under the reciprocating action of the reciprocating thread 605, the roller 604 will intermittently rotate and squeeze the water-absorbing sponge 503 so that the water on the water-absorbing sponge 503 can be continuously extruded, avoiding the water-absorbing sponge 503 being saturated with too much water and affecting the water absorption of the water-absorbing sponge 503. The extruded water will be discharged out of the device from the drainage inclined groove 606.

[0064] S3: Recirculating spray: The water will push the rectangular plate 706 towards the hydraulic cylinder 702. At this time, the telescopic spring 707 undergoes tensile deformation. When the L-shaped groove 708 on the rectangular plate 706 moves out of the strip block 703, the water will drain from the L-shaped groove 708 to the left side of the strip block 703, preparing for the next cycle of spraying the soot. During the continuous reciprocating movement of the hydraulic cylinder 702, the spray holes 704 will continuously spray the soot, achieving the effect of continuously filtering impurity particles.

[0065] S4: Separating soot impurities: The triangular belt orifice plate 802 will return under the elastic force of the limit spring 803. During the continuous rotation of the rotating shaft 4, the triangular belt orifice plate 802 will continuously reciprocate and shake. The shaking will cause the impurity particles staying on the surface of the triangular belt orifice plate 802 to slide down to the lower sides of the two inclined surfaces of the triangular belt orifice plate 802. The sliding impurity particles will enter the two collection boxes 806 for collection. Correspondingly, the water will enter the spray chamber 701 through the holes on the triangular belt orifice plate 802. The continuous shaking can prevent the holes on the triangular belt orifice plate 802 from being blocked, thus affecting the effect of filtering soot impurities.

10. A method for using a prefabricated building material steel bar welding device, using the prefabricated building material steel bar welding device as claimed in claim 9, characterized in that: The steps are as follows: S1: reducing air humidity: when the gas passes through the cylinder (2), the moisture in the gas will pass through the water-absorbing sponge (503), and the water-absorbing sponge (503) will filter out the moisture in the air, thereby reducing the humidity of the air blown into the welding box (1). After the air is blown into the welding box (1) from the wind guide hood (505), the gas above the welding box (1) will be discharged from the top of the welding box (1) under the push of the blown-in gas, so that the gas in the welding box (1) is in a low-humidity state, effectively avoiding the high humidity in the air causing the weld to absorb more hydrogen elements, hydrogen accumulation in the weld metal, and forming hydrogen embrittlement, which significantly reduces the strength of the weld, especially the toughness; S2: Squeezing out water: As the threaded plate (602) is constantly rotating, the corresponding roller (604) will also rotate at the same time. The roller (604) will rotate to squeeze the water on the water-absorbing sponge (503). Under the reciprocating action of the reciprocating thread (605), the roller (604) will intermittently rotate to squeeze the water-absorbing sponge (503) so that the water on the water-absorbing sponge (503) can be continuously squeezed out, thereby preventing the water on the water-absorbing sponge (503) from being over-saturated and affecting the water absorption of the water-absorbing sponge (503). The squeezed water will be discharged from the device through the drainage chute (606); S3: Circular spraying: Water pushes the rectangular plate (706) to move in the direction close to the hydraulic cylinder (702), and the telescopic spring (707) is stretched and deformed. When the L-shaped groove (708) on the rectangular plate (706) leaves the strip block (703), water is discharged from the L-shaped groove (708) to the left side of the strip block (703), preparing for the next cyclic spraying of smoke and dust. During the continuous reciprocating motion of the hydraulic cylinder (702), the spray hole (704) will continuously spray smoke and dust, achieving the effect of continuously filtering foreign particles; S4: Separation of smoke and dust impurities: The triangular perforated plate (802) will return under the elastic force of the limit spring (803). During the continuous rotation of the rotating shaft (4), the triangular perforated plate (802) will continuously swing back and forth. The swinging will cause the impurity particles remaining on the surface of the triangular perforated plate (802) to slide down the two inclined surfaces of the triangular perforated plate (802). The sliding impurity particles will enter the two collection boxes (806) for collection, and the corresponding water will enter the spray chamber (701) through the holes on the triangular perforated plate (802). The continuous shaking can prevent the holes on the triangular perforated plate (802) from being blocked, thereby affecting the effect of filtering smoke and dust impurities.
