[0020] A dust collecting device, as shown in Figure 1 includes a straight pipe part 1, a branch pipe part 2, the branch pipe part 2 is connected to the straight pipe part 1 at one end to form a tee shape, the straight pipe part 1 has an upper end and a lower end, the upper end is a gas inlet 3, and the lower end is a dust collecting end 4. In actual use, the gas enters the straight pipe part 1 and flows out from the branch pipe part 2, so that the gas forms a turning flow trajectory in the device. The dust particles can be separated by colliding when the gas flow turns, and the probability of dust entering the pump is reduced.

[0021] Specifically, as shown in Figure 1 The branch pipe part 2 is connected to the straight pipe part 1 at a position, and a core pipe 5 is arranged at the position. The straight pipe part 1 forms a sleeve 6 arranged outside the core pipe 5. The branch pipe part 2 is connected to the sleeve 6, and the communication port of the branch pipe part 2 on the sleeve 6 faces the middle position of the core pipe 5. The core pipe 5 with a relatively small diameter and the sleeve 6 with a relatively large diameter are arranged, so that when the gas flow flows from the relatively small core pipe 5 to the relatively large sleeve 6, a sudden pressure drop is formed, thereby reducing the gas flow rate and facilitating the separation of dust falling.

[0022] Further, the straight pipe part 1 includes the core pipe 5 and the sleeve 6. The upper end of the sleeve 6 is coaxially arranged with the core pipe 5. The upper end of the sleeve 6 is provided with a ring part 7 for sealing. The inner ring of the ring part 7 is sealingly connected to the outer wall of the core pipe 5, and the outer ring of the ring part 7 is sealingly connected to the upper end of the sleeve 6, so that the ring part 7 forms a seal at the upper connection of the core pipe 5 and the sleeve 6. The upper end of the sleeve 6 connected to the core pipe 5 is sealed by the ring part 7, so that the core pipe 5 and the sleeve 6 are connected as a whole.

[0023] Further, the upper end of the core pipe 5 is provided with a first gate valve 8 which is connected to the core pipe 5 through a flange. The lower end of the branch pipe part 2 is provided with a flange-connected second gate valve 17 which is used to be connected with the pump end. Through the setting of the two gate valves, the opening and closing of the pipeline can be manually controlled, and when closed, the equipment parts can be repaired and replaced to ensure the normal operation of the machine and improve the production efficiency.

[0024] Further, the lower end of the sleeve pipe 6 is provided with a detachable dust collecting cup 9, and the bottom of the dust collecting cup 9 is provided with an openable bottom opening 10 for cleaning dust. Specifically, the detachable dust collecting cup 9 includes a cup body 11 which is a cylindrical cylinder body, and the diameter of the cup body 11 is the same as that of the sleeve pipe 6. The upper end of the cup body 11 is provided with an upper flange 12, and the lower end of the sleeve pipe 6 is provided with a connecting flange 13. The cup body 11 is flange-connected with the connecting flange 13 through the upper flange 12. During use, the connecting flange 13 and the upper flange 12 can be detached, which is convenient for cleaning the inner wall of the core pipe 5 and the sleeve pipe 6, and replacing the dust collecting cup 9 and other components.

[0025] Further, the bottom opening 10 includes a lower flange 14 which forms the bottom of the cup body 11. The lower flange 14 is parallel to the upper flange 12. The bottom opening 10 also includes an openable bottom blind plate 15 which is installed on the lower flange 14 to form a seal for the bottom of the sleeve pipe 6. The blind plate at the bottom of the cup body 11 can be opened, and the dust particles deposited in the dust collecting cup 9 can be cleaned out, which is convenient for subsequent use. Further, the lower end of the core pipe 5 extends upwardly to the upper part of the connecting flange 13, so that the space between the lower end of the core pipe 5 and the bottom of the dust collecting cup 9 forms a containing space for dust settlement.

[0026] Further, the branch pipe part 2 extends obliquely downwardly, so that the branch pipe part 2 and the straight pipe part 1 form an opening downwardly inclined angle 16, and the angle 16 is 30-60°. In this embodiment, the branch pipe is arranged to be inclined downwardly, which can increase the angle of the airflow returning flow, and can also reduce the probability of dust entering the branch pipe part 2 to a certain extent.

[0027] The working principle of this device is to prevent the dust particles formed by the condensation of the generated gas dust on the inner wall of the pipe from being directly sucked into the PUMP and causing the PUMP to be stuck. The toxic and harmful gas sucked by the PUMP has adhesion, and too much condensation on the inner wall of the pipeline will generate dust particles. By installing this device, the path of the gas sucked by the PUMP is changed, so that the toxic and harmful gas sucked by the PUMP passes through the dust collecting cup 9 first and then is sucked into the PUMP. The dust particles formed by the condensation of the toxic and harmful gas on the inner wall of the pipe directly fall into the dust collecting cup 9, preventing the dust particles from being directly sucked into the PUMP and causing the PUMP to be stuck.

[0028] The bottom blind plate 15, the sealing ring and the C-shaped clamp are locked at the bottom dust collecting cup 9, the C-shaped clamp tightly seals the bottom blind plate 15, the sealing ring and the lower flange 14, and the collected gas dust particles are conveniently cleaned periodically. The gate valves at the upper and lower ends are used to prevent the device from malfunctioning, to keep the pressure in the pipe for a short time under the condition that the machine does not stop, and to ensure the normal operation of the machine, so as to facilitate the replacement and maintenance of the device. The gas dust enters from the first gate valve 8, enters the dust collecting cup 9 through the core pipe 5, and the dust collecting cup 9 is used to collect the dust particles formed by the condensation of gas dust. The bottom blind plate 15 can be disassembled to clean the gas dust particles periodically, and then enters the PUMP through the second gate valve 17. The two gate valves can be manually opened and closed, and when closed, they can be used to replace and maintain the device, ensure the normal operation of the machine, and improve the production efficiency.

[0029] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
