[0003] The waste gas generated in the current hot degreasing flux pre -coating continuous production line is often transported through pipeline, when the waste gas is transmitted in the pipeline, the particulate matter in the waste gas often adheres to the pipeline, when the particulate dust on the pipeline adheres more, the efficiency of the pipeline to transport waste gas is affected, and the workpiece is also easily polluted when dust accumulates and falls. SUMMARY

[0005] To achieve the above object, the utility model provides the following technical scheme:

[0006] A kind of waste gas treatment device of hot degreasing flux pre -coating continuous production line, including flux pre -coating production line main body, the flux pre -coating production line main body is provided with transmission pipeline main body, servo motor is fixed on the outer side of transmission pipeline main body top, the output of servo motor is fixed with connecting rod, the connecting rod extends to transmission pipeline main body interior, first dust screen is fixed in transmission pipeline main body interior, connecting disc is fixed in the bottom of connecting rod, two cleaning rods are fixed on the side of connecting disc symmetrically, electric valve is provided in the end of transmission pipeline main body close to flux pre -coating production line main body, cleaning pipeline is provided in the end of transmission pipeline main body away from electric valve, dust extraction device is fixed on the side of flux pre -coating production line main body, transmission pipeline main body is connected to dust extraction device interior by cleaning pipeline.

[0007] Furthermore, the dust collection device includes a fan, which is fixed below the dust collection device. A second dustproof net is fixed at the bottom of the inside of the dust collection device. Two sealing doors are symmetrically arranged at the end of the dust collection device away from the main body of the flux pre-coating production line. One end of each sealing door is rotatably connected to the dust collection device.

[0008] Furthermore, the cleaning rod is in the shape of an inverted "L", and bevels are provided on both sides of the cleaning rod.

[0009] Furthermore, the lower part of the connecting rod is rotatably connected to the first dustproof net via a bearing, and the top end of the cleaning rod is attached to the bottom end of the first dustproof net.

[0010] Furthermore, a limit baffle is fixed inside the dust collection device near the sealed door, and the second dustproof net is positioned above the fan's air intake.

[0011] Furthermore, the limiting baffle is fitted to the sealing door, and a sealing rubber is provided at the fitting point between the limiting baffle and the sealing door.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, a servo motor is installed above the main body of the transmission pipe, and a first dustproof net is installed inside the main body of the transmission pipe to prevent dust from flowing into the rear section of the main body of the transmission pipe. At the same time, the servo motor drives the connecting plate to rotate, which in turn drives the cleaning rod to rotate, causing the cleaning rod to scrape off the dust inside the main body of the transmission pipe. When cleaning the dust, the electric valve is closed, so that the dust falls onto the electric valve and is then sucked away by the dust suction device. This solves the problem that the exhaust gas generated in the current continuous production line for hot degreasing flux pre-coating is often transported through pipelines. When the exhaust gas is transported in the pipeline, the particulate matter in the exhaust gas often adheres to the pipeline. When there is a lot of dust adhering to the pipeline, it will affect the efficiency of the pipeline in transporting exhaust gas. At the same time, the dust accumulation and falling can easily contaminate the workpiece.

[0014] 2. In this utility model, a cleaning pipe is connected to a dust collection device, and the dust collection device is fixed on one side of the main body of the flux pre-coating production line. The dust collection device is equipped with a fan. When the fan is started, a negative pressure is formed inside the dust collection device, which causes the fan to suck dust into the dust collection device. At the same time, the second dustproof net blocks the dust from being sucked into the fan. The sealed door makes it easier for workers to clean the inside of the dust collection device.

[0021] To make the purpose, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4A waste gas treatment device for a continuous hot degreasing flux pre-coating production line includes a flux pre-coating production line body 1, a transmission pipe body 2 on the flux pre-coating production line body 1, a servo motor 3 fixed on the upper outer side of the transmission pipe body 2, a connecting rod 4 fixed at the output end of the servo motor 3, the connecting rod 4 extending into the interior of the transmission pipe body 2, a first dustproof net 5 fixed inside the transmission pipe body 2, a connecting plate 6 fixed at the bottom end of the connecting rod 4, two cleaning rods 7 symmetrically fixed on the side of the connecting plate 6, an electric valve 8 installed at one end of the transmission pipe body 2 near the flux pre-coating production line body 1, a cleaning pipe 9 installed at the other end of the transmission pipe body 2 away from the electric valve 8, a dust collection device 10 fixed on one side of the flux pre-coating production line body 1, and the transmission pipe body 2 connected to the dust collection device 10 through the cleaning pipe 9, making it easy to clean the dust inside the transmission pipe body 2.

[0023] Specifically, the cleaning rod 7 is in the shape of an inverted "L" and has beveled surfaces on both sides. The connecting rod 4 is rotatably connected to the first dustproof net 5 via a bearing. The top of the cleaning rod 7 is attached to the bottom of the first dustproof net 5, thereby improving the cleaning efficiency of the cleaning rod 7.

[0024] As an optimization solution, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the dust collection device 10 includes a fan 11, which is fixed below the dust collection device 10. A second dustproof net 13 is fixed at the bottom of the inside of the dust collection device 10. Two sealing doors 12 are symmetrically arranged at one end of the dust collection device 10 away from the main body 1 of the flux pre-coating production line. One end of each sealing door 12 is rotatably connected to the dust collection device 10, so that the fan 11 sucks the dust into the dust collection device 10.

[0025] Specifically, a limiting baffle 14 is fixed inside the dust collection device 10 near the sealing door 12, and a second dustproof net 13 is set above the air intake of the fan 11. The limiting baffle 14 is in contact with the sealing door 12, and a sealing rubber is provided at the contact point between the limiting baffle 14 and the sealing door 12 to ensure the sealing of the dust collection device 10.

[0026] Working principle: When there is a lot of dust inside the main body 2 of the transmission pipe, the electric valve 8 is activated to close it. Then, the servo motor 3 is activated, which drives the connecting rod 4 to rotate. This causes the connecting rod 4 to rotate the connecting plate 6, and the connecting plate 6 to rotate the cleaning rod 7. This allows the cleaning rod 7 to scrape the dust off the bottom of the first dustproof net 5 and the inner side of the main body 2 of the transmission pipe. At the same time, the dust falls above the electric valve 8. Then, the fan 11 is activated, which draws out the air from the vacuum cleaner 10, creating a negative pressure inside the vacuum cleaner 10. This allows the vacuum cleaner 10 to draw the particulate dust on the electric valve 8 into the vacuum cleaner 10 through the cleaning pipe 9. Meanwhile, the second dustproof net 13 prevents dust from entering the fan 11. When there is a lot of dust inside the vacuum cleaner 10, the dust inside the vacuum cleaner 10 can be cleaned by opening the sealing door 12.
