A No. 1 discharge port is arranged at the lower part of the driving box of the No. 1 tube chain conveyor, a No. 2 feed port is arranged on the feeding pipe of the No. 2 tube chain conveyor, and the No. 1 discharge port is connected with the No. 2 feed port, and a No. 2 discharge port is arranged at the lower part of the driving box of the No. 2 tube chain conveyor, a No. 3 feed port is arranged on the feeding pipe of the No. 3 tube chain conveyor, and the No. 2 discharge port is connected with the No. 3 feed port, and a No. 3 discharge port is arranged at the lower part of the driving box of the No. 3 tube chain conveyor, and the No. 3 discharge port is connected with the inlet of the vibrating screen.

[0004] Referring to the above technical solution, the tube chain conveyor usually includes a conveying pipe, a scraper for pushing the magnesium powder, and chain links arranged between the scrapers. When the tube chain conveyor conveys the magnesium powder, there will be residual magnesium powder on the scraper and the chain links. On the one hand, there is a risk that these magnesium powders will enter the interior of the driving parts as the chain links move, which may cause equipment failure and affect the transportation of the magnesium powder. On the other hand, it will also cause waste of magnesium powder. Summary of the invention

[0005] In order to solve the technical problem that magnesium powder enters into the driving part due to residual magnesium powder on the scraper and chain links, affecting the magnesium powder conveying effect and causing magnesium powder waste, the present application provides a sealed conveying device for magnesium powder.

[0006] The present application provides a sealed conveying device for magnesium powder, which adopts the following technical scheme: a sealed conveying device for magnesium powder production, comprising a conveying pipe, a chain link, a scraper, and a feed port and a discharge port opened on the conveying pipe, and also comprising: a driving mechanism for driving the chain link and the scraper to move, and a cleaning mechanism for cleaning the chain link and the scraper; the driving mechanism comprises an installation box arranged between the conveying pipes and a first motor installed on the installation box, a conveying sprocket is horizontally fixedly connected to the driving shaft of the first motor, and the conveying sprocket can drive the chain link to move by cooperating with the chain link, the conveying pipe comprises a feed pipe and a return pipe, and the pipe from the feed port to the discharge port is the feed pipe, and the pipe from the discharge port, the installation box to the feed port is the return pipe; the cleaning mechanism comprises a rotating pipe rotatably connected to the return pipe, a cleaning brush is installed on the inner side wall of the rotating pipe, a discharge pipe is connected to the return pipe between the rotating pipe and the installation box, a negative pressure source is arranged at one end of the discharge pipe away from the return pipe, and a rotating assembly is arranged on the return pipe, and the rotating assembly is used to drive the rotating pipe to rotate.

[0007] By adopting the above technical solution, when magnesium powder needs to be transported, the driving shaft of the first motor rotates to drive the conveying sprocket to rotate, the conveying sprocket rotates to mesh with the chain links and drives the chain links and scrapers to move, the scrapers move and cooperate with the feed pipe to transport the magnesium powder; after completing the transportation of the magnesium powder, the chain links and scrapers move to the rotating ring, the rotating tube rotates to drive the cleaning brush to rotate, the cleaning brush cleans the chain links and scrapers, and the magnesium powder falls into the rotating tube. Under the action of the negative pressure source, the magnesium powder that falls into the rotating tube flows out from the discharge pipe.

[0008] The present application can separate the magnesium powder remaining on the chain links and the scraper before entering the driving mechanism during each cyclic conveying, and the separated magnesium powder can be collected under the action of the negative pressure source, thereby reducing the risk of magnesium powder entering the rotating mechanism and causing device failure, which is beneficial to ensuring the conveying effect of the magnesium powder. At the same time, the collected magnesium powder can be added back to the feed port, reducing the waste of magnesium powder.

[0009] Optionally, the diameter of the rotating tube is larger than the diameter of the return tube.

[0010] By adopting the above technical solution and setting the diameter of the rotating tube, it is possible to reduce the scraper from continuing to contact with the magnesium powder falling on the bottom of the rotating tube after being cleaned, which is beneficial to improving the cleaning effect of the scraper.

[0011] Optionally, a correction mechanism is provided in the installation box, and the correction mechanism is used to make the chain links vertical.

[0012] By adopting the above technical solution, when the cleaning brush rotates to clean the chain links, the chain links may be pushed to rotate to a horizontal state. The setting of the correction mechanism can adjust the chain links to rotate the chain links to a vertical state, thereby facilitating the engagement of the chain links with the conveying sprocket, reducing the risk of the chain links not being able to engage with the conveying sprocket, and reducing the difficulty of engagement.

[0013] Optionally, the correction mechanism includes a pair of support plates horizontally arranged in an installation box, which are arranged between the conveying sprocket and the rotating tube and are located on one side of the chain link. A plurality of support rods are vertically arranged between the pair of support plates. Adjacent support rods are connected by connecting rods and together form chain links connected end to end.

A top block is fixedly sleeved on each support rod.

[0014] By adopting the above technical solution, when the chain link and the scraper move, the scraper pushes the top block to move, and the movement of the top block drives the support rod and the connecting rod to move along the sliding groove. At the same time, during the movement, the top block can push the chain link, and the chain link rotates and maintains a vertical state.

[0015] Optionally, when the top block moves to a side close to the chain link, the end position of the top block can coincide with the position of the side close to the top block when the chain link is vertical.

[0018] By adopting the above technical solution, when the rotating tube needs to rotate, the driving shaft of the second motor rotates to drive the first gear to rotate, and the rotation of the first gear drives the second gear and the rotating tube to rotate, and the structure is simple.

[0019] Optionally, both ends of each support rod are rotatably connected to rollers, and tracks are provided on the support plate corresponding to the rollers, and the tracks can be connected to the sliding grooves.

[0020] By adopting the above technical solution, the setting of the rollers and the track can reduce the resistance encountered by the support rod during the movement, making it easier for the support rod to move.

[0021] Optionally, the return pipe is connected to the rotating tube via a conical tube, the rotating tube is rotatably connected to the conical tube, the discharge pipe is fixedly connected to the conical tube, and the distance from the inner side of the side wall of the installation box close to the rotating tube to one end of the conical tube close to the installation box is smaller than the distance between adjacent scrapers.

[0022] By adopting the above technical solution, during the movement of the chain links and the scraper, when the scraper moves to the position between the installation box and the conical tube, the scraper located between the installation box and the conical tube and the scraper located on the side of the rotating tube away from the installation box can seal the space, and at this time, magnesium powder can be easily discharged through the discharge pipe under the action of the negative pressure source; when the scraper moves out of the position between the installation box and the conical tube, the sealed space is opened, and air can enter the rotating tube area, reducing the risk of too low air pressure in the return pipe due to the action of the negative pressure source, which is beneficial to ensure the life of the return pipe.

[0023] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The present application can separate the magnesium powder remaining on the chain links and scrapers before entering the driving mechanism during each cyclic conveying, and the separated magnesium powder can be collected under the action of a negative pressure source, thereby reducing the risk of magnesium powder entering the rotating mechanism and causing device failure, which is beneficial to ensuring the conveying effect of the magnesium powder.

[0045] After completing the transportation of magnesium powder, the chain link 2 and the scraper 21 move to the rotating tube 41. The rotation of the rotating tube 41 drives the cleaning brush 42 to rotate. The cleaning brush 42 cleans the chain link 2 and the scraper 21, and the magnesium powder falls into the rotating tube 41. Under the action of the negative pressure source, the magnesium powder falling into the rotating tube 41 flows out from the discharge pipe 43.
