[0002] Magnesium alloy covering agent is an auxiliary material used in the magnesium alloy smelting process. Its main function is to prevent oxidation, pollution, burning, slag and other phenomena, thereby improving the quality and performance of magnesium alloy.

[0003] The production of covering agents generally involves formulation, melting, solidification, granulation, mixing, foaming, and molding and granulation. After granulation, the contact area between the material and the air becomes larger. During storage and transportation, a large amount of dust will adhere to the material, which will lead to poor quality of the covering agent. Therefore, the dust is generally removed during foaming. In response to the above technical problems, a Chinese patent with patent announcement number CN113083459A performs a preliminary filtration of the covering agent through a filter plate during use, and then drives the adsorption rod to rotate and adsorb the dust in the covering agent through a micro motor.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The material will have a certain initial velocity and fly out of the through slot. The material flying out of the placement cylinder will collide with the filter screen, then the material will rebound and fall. The rebounded material will collide with the subsequent material flying out of the placement cylinder again. The moving speed of the rebounded material is slow and the kinetic energy is small. Therefore, the material that rebounds after the collision will continue to fall and collide with the filter screen again. The material that collides with the rebounded material will continue to move and collide with the filter screen, thereby realizing multiple collisions between materials and between materials and the filter screen. Under the action of collision vibration and inertia, the dust on the surface of the material can be separated. , improving the dust separation effect, at the same time the air pump draws out the air in the connecting frame, and then the air in the shell will pass through the filter screen into the connecting frame and be drawn out, the outside air can enter the shell through the air inlet pipe, the air will carry the dust detached by the material collision through the filter screen, and then the dust is drawn out of the shell with the air, thereby realizing the dust separation, and the air entering the shell flows from the bottom to the top, so that the air can further clean the fallen material, and at the same time can make the fallen dust move upward, reducing the amount of dust moving downward, and further improving the dust cleaning effect.

[0015] 2. The material moves downward along the channel formed by the diverter plate on the second guide plate, and then falls between the two groups of cleaning shafts. The brushes on the two adjacent groups of cleaning shafts support the material. Since the cleaning shafts rotate in the same direction and are tilted, the material particles will flip over under the drive of the two groups of brushes, and move downward along the cleaning shafts under the action of gravity, so that the material particles can roll irregularly in the process of falling, and then the brushes can clean the material more comprehensively, further ensuring the separation effect of dust and material, and ensuring the cleanliness of the material. Since the brushes are soft materials, part of the material will fall down onto the brushes in the lower row during the movement, thereby realizing the diversion of the material, avoiding the inability of the brushes to fully clean the material due to material accumulation, and further improving the cleaning effect of the dust on the material.

[0016] 3. The air flows upward along the guide trough into the cleaning chamber, and then flows upward through the feed end of the cleaning chamber. When the air flows upward in the cleaning chamber, it will drive the dust upward to separate the dust in the cleaning chamber. At the same time, the air flow rate can be accelerated by cooperating with the air blower and the air pump, further accelerating the circulation flow rate of the air in the shell, further improving the ability of the air to carry dust separation, and improving the dust removal effect.

One end of the fourth guide plate 30 away from the grinding cylinder 31 is fixedly connected to the inner wall of the shell 1. A second rotating power component 32 is fixedly installed on the bottom surface of the shell 1. The output shaft of the second rotating power component 32 extends into the grinding cylinder 31 and its output shaft is coaxially arranged with the grinding cylinder 31. A plurality of groups of grinding blades 33 distributed at intervals are fixedly installed on the output shaft of the second rotating power component 32. A discharge port connected to the grinding cylinder 31 is opened on the bottom surface of the shell 1, and a sealing cover 34 is provided on the discharge port.

[0027] In actual application of this embodiment, the cover plate 5 is opened, and the mixed granular raw materials are transported into the housing 1 through the feed pipe 4. The granular raw materials fall into the storage cylinder 2 along the feed pipe 4, and then the cover plate 5 is closed; The motor drives the rotating shaft 6 and the push plate 7 to rotate, and the air pump 11 is turned on at the same time. When the push plate 7 rotates, it can push part of the material at the bottom of the storage cylinder 2 to move with it. When the material moves to the through slot on the upper part of the storage cylinder 2, since there is no restriction from the wall of the storage cylinder 2, the material will have a certain initial velocity and fly out of the through slot. The material flying out of the storage cylinder 2 collides with the filter screen 9, and then the material will rebound and fall. The material after rebounding will collide with the subsequent material flying out of the storage cylinder 2 again, and the movement speed of the material after rebounding is slow and the kinetic energy is small, so the material rebounding after the collision will continue to fall and collide with the filter screen 9 again, and the material colliding with the material after rebounding will continue to move and collide with the filter screen 9, thereby realizing multiple collisions between materials and materials, and between materials and the filter screen 9. Under the action of collision vibration and inertia, the dust on the surface of the material can be detached, thereby improving the dust detachment effect; At the same time, the air pump 11 draws out the air in the connection frame 10, and then the air in the shell 1 passes through the filter 9 into the connection frame 10 and is drawn out, and the outside air can enter the shell 1 through the air inlet pipe 22, and the air will carry the dust separated by the collision of the material through the filter 9, and then the dust is drawn out of the shell 1 with the air, thereby realizing the separation of the dust, and the air entering the shell 1 flows from the bottom to the top, so that the air can further clean the falling material, and at the same time can make the falling dust move upward, reduce the amount of dust moving downward, and further improve the dust cleaning effect; The cleaned material falls downward onto the fourth guide plate 30 and then enters the grinding cylinder 31 along the fourth guide plate 30. The grinding blade 33 is driven by the second rotating power member 32 to rotate for grinding. After grinding to a set particle size, the material stops, and the sealing cover 34 is removed, and the ground material can fall downward.

[0028] In an embodiment of the present invention, the second rotating power member 32 is a second motor, and of course, it can also be other components capable of outputting rotating power, such as a hydraulic motor, and the grinding blade 33 is driven to rotate by the second motor.

[0029] like Figure 1-Figure 6 As shown, a magnesium alloy covering agent preparation device provided by the present invention is provided. A first closing plate 15 and a second closing plate 16 are fixedly installed in a shell 1. The first closing plate 15, the second closing plate 16 and the inner wall of the shell 1 form a cleaning chamber 17. A brush 26 is arranged in the cleaning chamber 17. The cleaning chamber 17 is provided with a feed end and a discharge end. Both the feed end and the discharge end are open structures. The second closing plate 16 is fixedly connected to a third guide plate 13 located at the feed end. One end of the third guide plate 13 away from the second closing plate 16 is fixedly connected to the side wall of the storage cylinder 2. The discharge end is connected to a guide groove 18. The bottom side wall of the cleaning chamber 17 is an inclined structure and the discharge end is located at the lower end of the bottom side wall. The guide groove 18 extends along the bottom side wall of the cleaning chamber 17.

[0030] Specifically, multiple groups of diverter plates 14 with triangular cross-sections are fixedly mounted on the third guide plate 13 . The multiple groups of diverter plates 14 are distributed in parallel and a gap is provided between two adjacent groups of diverter plates 14 . An end of the diverter plate 14 close to the storage tube 2 is provided with an inclined surface structure.

[0031] Specifically, a cleaning shaft 25 is rotatably installed on the vertical section of the first closing plate 15, and multiple groups of cleaning shafts 25 are divided into multiple rows and linearly distributed. Multiple groups of cleaning shafts 25 in the same row are rotatably connected to each other, and a first rotating power member 29 that drives one group of cleaning shafts 25 to rotate is fixedly installed on the first closing plate 15. The positions of the multiple groups of cleaning shafts 25 in the same row correspond to the position of the diverter plate 14. The cleaning shaft 25 is located below the discharge end of the third guide plate 13. The cleaning shaft 25 is set at an angle with the horizontal plane. The brush 26 is fixedly installed on the cleaning shaft 25 and arranged in a cylindrical shape. A gap is set between the brushes 26 on two adjacent groups of cleaning shafts 25 in the same row.

[0032] Specifically, multiple groups of air intake pipes 22 are provided and connected to the material guide trough 18 . The multiple groups of air intake pipes 22 are connected to a connecting box 23 fixedly installed on the side of the shell 1 . A hair dryer 24 is fixedly installed on the side of the shell 1 , and the air outlet end of the hair dryer 24 is connected to the connecting box 23 .

[0033] Specifically, a second guide plate 12 is fixedly installed at the lower end of the baffle 8. The second guide plate 12 is set at an angle with the horizontal plane. The second guide plate 12 is fixedly connected to the first closing plate 15. The end of the second guide plate 12 away from the baffle 8 is fixedly connected to the end of the diverter plate 14 close to the storage tube 2.

[0034] Specifically, the material guide trough 18 is connected to a temporary storage trough 19 , a bottom plate 21 is provided at the bottom of the temporary storage trough 19 , and a telescopic member 20 is fixedly installed in the housing 1 to drive the bottom plate 21 to move up and down.

[0035] In actual application of this embodiment, one group of cleaning shafts 25 in the same row of cleaning shafts 25 is driven to rotate by the first rotating power member 29, and multiple groups of cleaning shafts 25 in the same row are connected to each other by a synchronous belt 28 and a synchronous wheel 27, thereby realizing synchronous rotation of multiple groups of cleaning shafts 25; After the material hits the filter screen 9, it moves along the second guide plate 12 to the third guide plate 13. Due to the setting of the diverter plate 14, the material moves downward along the channel formed by the diverter plate 14 on the second guide plate 12, and then the material falls between the two groups of cleaning shafts 25, and the brushes 26 on the two adjacent groups of cleaning shafts 25 support the material. Since the cleaning shafts 25 rotate in the same direction and are tilted, the material particles will be turned over by the two groups of brushes 26, and will also move downward along the cleaning shafts 25 under the action of gravity, so that the material particles can roll irregularly during the falling process, and then the brushes 26 can be used to clean the material more comprehensively, further ensuring the separation effect of dust and material, and ensuring the cleanliness of the material. Since the brushes 26 are made of soft materials, part of the material will fall downward onto the brushes 26 in the lower row during the movement, thereby realizing the diversion of the material, avoiding the inability of the brushes 26 to fully clean the material due to the accumulation of materials, and further improving the cleaning effect of the dust on the material. While the material is falling, the blower 24 conveys air into the connecting box 23, and the air enters the guide groove 18 through the air inlet pipe 22. The air flows upward along the guide groove 18 and enters the cleaning chamber 17, and then flows upward through the feeding end of the cleaning chamber 17. When the air flows upward in the cleaning chamber 17, it will drive the dust to move upward, so as to separate the dust in the cleaning chamber 17. At the same time, the blower 24 cooperates with the air pump 11 to accelerate the flow speed of the air, further accelerate the circulation flow speed of the air in the shell 1, further improve the ability of the air to carry dust separation, and improve the dust removal effect. Since the setting of the diverter plate 14 forms a channel, the air at the entrance of the flow channel has a reduced range of the channel opening, thereby increasing the air flow speed, and then the air will exert a force on the material at the channel opening, causing the material at the channel opening to move irregularly, thereby avoiding blockage of the channel opening and ensuring smooth movement of the material. After the material falls to the bottom of the cleaning chamber 17, it moves along the material guide groove 18 and enters the temporary storage groove 19. The lower end of the temporary storage groove 19 is closed by the bottom plate 21 to prevent air from flowing to the bottom of the shell 1. After all the materials are cleaned, the telescopic member 20 drives the bottom plate 21 to move downward. At this time, the cleaned materials can fall into the grinding cylinder 31. During subsequent grinding, the bottom plate 21 closes the temporary storage groove 19 again.

[0036] In one embodiment of the present invention, the first rotating power component 29 is a first motor, and of course it can also be other components that can output rotational power, such as a hydraulic motor. The first motor drives multiple groups of cleaning shafts 25 to rotate synchronously. The telescopic component 20 is an electric telescopic rod, and of course it can also be other components that can actively change the length, such as a hydraulic cylinder, and the electric telescopic rod drives the base plate 21 to move up and down.
