The multiple motors are drive-connected to the multiple drive rollers in a one-to-one correspondence, and the multiple drive rollers and the multiple rotating rollers are staggered and located in multiple conveying troughs.

[0010] Preferably, the processing box further comprises a sewage trough, which is connected to the plurality of conveying troughs, and the bottom ends of the plurality of conveying troughs are gradually inclined from a side away from the conveying trough to an end close to the conveying trough.

[0011] Preferably, the drying assembly includes a heating assembly provided at each of the two drying chambers, the heating assembly includes a partition plate provided on the processing box, an electric heating wire and a blower provided on the processing box, and the partition plate has two pairs of relatively distributed air guide channels.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects:

DETAILED DESCRIPTION

[0018] Example 1

[0019] like Figure 1-Figure 3As shown, the embodiment of the present invention proposes an integrated spraying and drying equipment for building steel structure accessories, including a processing box 1, a spraying assembly, a drying assembly and a fume circulation assembly. The processing box 1 has a spraying channel 101, and a plurality of conveying troughs 102 and two drying chambers 104 all connected to the spraying channel 101. The spraying channel 101 has a conveying assembly; the spraying assembly is arranged on the processing box 1; the drying assembly is arranged in the two drying chambers 104, and the drying assembly includes a heating assembly arranged at each of the two drying chambers 104. The heating assembly includes a partition plate 14 arranged on the processing box 1, a The heating wire 15 and the blower 16 are placed on the processing box 1, and the partition plate 14 has two pairs of relatively distributed air guide channels. The two blowers 16 face different directions respectively. One blower 16 blows air toward the spray channel 101, and the other blower 16 blows air toward the heating wire 15, so that the spray channel 101 and the two drying chambers 104 cooperate to form a hot air circulation, so as to keep the air inside the processing box 1 stable, so as to keep the curing speed of the paint consistent, so as to avoid the uncured paint from contacting the conveying component, resulting in low quality of the paint on the object.

[0020] The flue gas circulation component is arranged on the processing box 1. The flue gas circulation component includes an air intake pipe 4 and an air pump 2 connected to the top of the processing box 1, a ventilation pipe 21 connected to the air pump 2, a filter box 3 connected to the ventilation pipe 21, and a control valve 5 arranged on the air intake pipe 4. The air intake pipe 4 and the control valve 5 are respectively located on both sides of the top of the processing box 1.

[0021] When this embodiment is used, the worker puts a batch of steel structure accessories that need to be sprayed with paint into the spray channel 101, then closes and rotates the closed door set on the processing box 1, and controls the drive assembly to drive the steel structure accessories to move through the control panel 7 set on the processing box 1. At the same time, the spray assembly sprays the steel structure accessories in all directions, and the heating wire 15 stabilizes the air temperature at a temperature suitable for hardening of the paint, and then the blower 16 allows the hot air to contact the paint, thereby hardening the paint. After the spraying and drying of the steel structure accessories is completed, the control panel 7 drives the vacuum pump 2 to start, and the vacuum pump 2 draws the inside of the processing box 1 into the filter box 3 for harmless filtration. When the air inside the processing box 1 is extracted to an air pressure lower than the outside air pressure, the control valve 5 is opened, and the outside air flows into the processing box 1 under the action of the air pressure, so as to avoid close contact between toxic gases and workers and cause deterioration of the workers' health.

[0022] Example 2

[0023] like Figure 1-Figure 3As shown, this embodiment proposes an integrated spraying and drying equipment for building steel structure accessories. Compared with Example 1, in this embodiment, the spraying assembly includes a feeding pump 13 connected to the processing box 1, a spray rack 12 connected to the processing box 1, and an atomizing head 11 connected to the spray rack 12 and the processing box 1, and the atomizing head 11 on the processing box 1 is located at the bottom end of the spray channel 101, the spray rack 12 is an inverted U shape, and has multiple ventilation channels on the spray rack 12, and the multiple atomizing heads 11 are all located on the side of the spray rack 12 facing the bottom of the spray channel 101, and the multiple ventilation channels can allow hot air to flow into the steel structure quickly, so that the paint sprayed on the surface of the steel structure can quickly harden.

[0024] When this embodiment is in use, the feed pump 13 delivers the paint to the processing box 1, the spray rack 12 and the atomizing head 11 in sequence. The multiple atomizing heads 11 are respectively located around the object in the vertical direction, so that when the conveying component conveys the steel structure, the paint will be evenly sprayed onto the surface of the steel structure, thereby avoiding dead corners in the spraying on the surface of the steel structure and reducing the workload of workers.

[0025] Example 3

[0026] like Figure 1-Figure 3 As shown, this embodiment proposes an integrated spraying and drying equipment for building steel structure accessories. Compared with Example 1, in this embodiment, the conveying component includes a plurality of motors 8 arranged on the processing box 1, and a plurality of driving rollers 9 and rotating rollers 10 rotatably arranged on the processing box 1. The plurality of motors 8 are driven and connected with the plurality of driving rollers 9 in a one-to-one correspondence. The plurality of driving rollers 9 and the plurality of rotating rollers 10 are staggered and located in a plurality of conveying troughs 102. Slopes 6 are also provided on both sides of the processing box 1 to facilitate workers to deliver the steel structure to the conveying component.

[0027] The processing box 1 also has a drain trough 103, which is connected to multiple conveying troughs 102. The bottom ends of the multiple conveying troughs are gradually inclined from the side away from the conveying trough 102 to the end close to the conveying trough 102. When cleaning the inside of the equipment, use a high-pressure water gun to flush the paint sprayed in the equipment. The water flow will carry the paint from the conveying trough 102 to the drain trough 103 and leave the equipment, so as to avoid the difficulty in removing dirt at the bottom of the conveying trough 102.

[0028] When this embodiment is used, workers place the steel structure on the driving roller 9, the motor 8 drives the multiple driving rollers 9 to rotate, and the multiple driving rollers 9 drive the steel structure to move slowly. The spraying assembly is located between the multiple driving rollers 9 and the rotating roller 10, so as to avoid part of the paint from being contaminated on the driving rollers 9 and the rotating rollers 10, resulting in insufficient paint thickness affecting the corrosion resistance of the steel structure.

[0029] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
