Description

Technical Field

[0001] The invention relates to the technical field of magnesium powder passivation, and in particular to a magnesium powder heating passivation device. Background Art

[0002] Magnesium powder passivation treatment refers to a surface treatment method that forms a dense passivation film on the surface of magnesium powder to improve the corrosion resistance and stability of magnesium powder. Passivation agents usually include organic acids, surfactants, wetting agents, corrosion inhibitors and other ingredients. These ingredients act together on the surface of magnesium powder to form a uniform and dense passivation film through chemical reactions.

[0003] A Chinese patent with announcement number CN213827003U discloses a device for improving the physical properties of magnesium powder, including a reaction tank, a motor frame connected to the top of the reaction tank, a motor installed on the top of the motor frame, the output end of the motor passes through the motor frame and is connected to a rotating rod, one end of the rotating rod passes through the reaction tank and extends to the inner cavity of the reaction tank, an electric heating plate is installed in the inner cavity of the reaction tank, a serpentine tube is installed at the bottom end of the inner cavity of the reaction tank, a water pump is installed on one side of the reaction tank through a tripod, the input end of the water pump is connected to a liquid storage tank through a first connecting pipe, and the output end of the water pump is connected to the serpentine tube through a second connecting pipe.

[0004] The above technical solution uniformly stirs the magnesium powder and the passivator through the cooperation of the motor frame, the motor, the rotating rod and the stirring blade, so as to achieve the purpose of sufficient reaction of the magnesium powder and the passivator; through the cooperation of the electric heating plate, the tripod, the liquid storage tank, the water pump, the first connecting pipe, the second connecting pipe, the serpentine pipe and the liquid outlet nozzle, the liquid outlet nozzle on the serpentine pipe sprays the passivation liquid on the surface of the magnesium powder to achieve uniform passivation of the magnesium powder. At the same time, the electric heating plate heats the inner cavity of the reaction tank to create the temperature conditions for the passivation of the magnesium powder and the passivation liquid, thereby accelerating the passivation of the magnesium powder.

[0005] However, in the actual implementation of the above technical solution, since the serpentine tube is arranged at the bottom of the reaction tank and the magnesium powder is also accumulated at the bottom of the reaction tank, the range of the serpentine tube spraying the passivation liquid upward is limited, and the magnesium powder located above is not easy to contact the passivation liquid. It takes a long time of stirring to passivate all the magnesium powder, and the passivation efficiency is low. In addition, during the spraying and stirring process, the magnesium powder may aggregate, resulting in uneven passivation.

[0006] Therefore, the art needs a magnesium powder heating passivation device to solve the above problems. Summary of the invention

[0007] The present invention provides a magnesium powder heating passivation device, aiming to solve the problems in the related art that the magnesium powder passivation device has low passivation efficiency for magnesium powder and magnesium powder agglomerates and agglomerates, resulting in uneven passivation of the magnesium powder.

[0008] A magnesium powder heating passivation device of the present invention comprises a reaction tube and a heating mechanism arranged on the reaction tube, a spraying mechanism for spraying a passivating agent is arranged on the top of the reaction tube, a mounting tube is rotatably connected in the reaction tube, a plurality of material distribution plates are evenly arranged along the circumference of the mounting tube, a driving assembly for driving the mounting tube to rotate is arranged on the reaction tube, the distances between the ends of the material distribution plates away from the mounting tube are different, and a stopper plate is extended from the ends of some material distribution plates away from the mounting tube;

[0009] The mounting tube is evenly spaced along its circumference and is provided with a plurality of interception tooth plates, the interception tooth plates are located on the side of the material dividing plate away from the rotation direction of the mounting tube, the interception tooth plates are rotationally connected to the mounting tube, and a force storage member is provided at the rotation connection;

[0010] A guide structure is provided on the reaction cylinder. When the installation cylinder rotates, the dividing plate drives the magnesium powder to move in the reaction cylinder. When the intercepting tooth plate contacts the guide structure, the guide structure drives the intercepting tooth plate to rotate and store force. When the intercepting tooth plate is separated from the guide structure, the force storage member drives the intercepting tooth plate to throw the magnesium powder agglomerates onto the corresponding dividing plate.

[0011] Beneficial effects: The present invention divides magnesium powder into several portions through a plurality of dividing plates, and sprays the passivator separately through the bottom of the spraying mechanism, thereby avoiding the problem of uneven spraying of the passivator caused by the accumulation of magnesium powder, and in the process of rotation of the mounting cylinder, the dividing plates can drive the magnesium powder to flip, so that the magnesium powder and the passivator are mixed in a shorter time, thereby improving the passivation efficiency; in addition, the intercepting tooth plate can pick up the magnesium powder agglomerates and throw them to the adjacent dividing plate, so that the magnesium powder agglomerates are impacted and dispersed, thereby further improving the uniformity of the mixing of the magnesium powder and the passivator, and when the intercepting tooth plate impacts the corresponding dividing plate, the magnesium powder attached to the intercepting tooth plate and the dividing plate will be shaken off and participate in the mixed passivation.

[0012] Preferably, the distance between one end of the plurality of material distributors away from the mounting barrel and the mounting barrel gradually decreases along the rotation direction of the mounting barrel, and one end of one of the material distributors away from the mounting barrel contacts the inner wall of the reaction barrel.

[0013] Beneficial effect: During the rotation of the installation barrel, the dividing plate can turn the magnesium powder in turn and drive part of the magnesium powder at the corresponding position to the top for spraying the passivating agent, and the dividing plate in contact with the inner wall of the reaction barrel can scrape away all the magnesium powder at the bottom of the reaction barrel and drive it to the top of the reaction barrel, avoiding the accumulation or residue of magnesium powder at the bottom of the reaction barrel, which is not easy to contact with the passivating agent.

[0014] Preferably, the intercepting gear plate includes a mounting plate and an intercepting rod evenly arranged on the mounting plate along the axial direction of the mounting cylinder, the end of the intercepting rod facing away from the mounting plate is elastically connected with a movable rod, the mounting plate is rotatably connected to the mounting cylinder, and the force storage member is arranged between the mounting plate and the mounting cylinder.

[0015] Beneficial effect: By elastically connecting the movable rod, the movable rod can always be in contact with the inner wall of the reaction tube during the rotation of the interception tooth plate, so that the movable rod and the interception rod cooperate to filter and remove the agglomerates in the magnesium powder.

[0016] Preferably, the guide structure includes a guide bar arranged at the bottom of the inner circumferential surface of the reaction cylinder, and an inclined guide surface is arranged at the end of the guide bar which is away from the rotation direction of the mounting cylinder. A limit rod corresponding to the position of the guide bar is fixedly connected to the mounting plate. When the limit rod contacts the guide bar, the guide bar pushes the limit rod to drive the mounting plate to rotate, so that the force storage part accumulates force. When the limit rod is separated from the guide bar, the force storage part drives the limit rod to drive the mounting plate to reset.

[0017] Preferably, the mounting tube is provided with a plurality of mounting grooves evenly spaced along its circumference, an elastic plate is fixedly connected in the mounting groove, a connecting rod is fixedly connected to the side of the elastic plate facing the inside of the mounting tube, the connecting rod is elastically connected to the mounting tube along the radial direction of the mounting tube, and a driving member is provided in the mounting tube for intermittently driving the connecting rod to move toward the center of the mounting tube, and when the driving member drives the connecting rod to move to a preset position, the connection with the connecting rod is cancelled.

[0018] Beneficial effect: when the driving member drives the connecting rod to move toward the center of the mounting tube, the connecting rod drives the elastic plate to undergo elastic deformation. When the driving member cancels the connection with the connecting rod, since the connecting rod is elastically connected to the mounting tube, the connecting rod will reset under the action of elastic force, and the elastic plate will vibrate, thereby driving the magnesium powder to vibrate, so that the magnesium powder and the passivator are in more uniform contact and the magnesium powder is prevented from agglomerating again. Moreover, when the elastic plate rotates to the bottom of the reaction tube, since the elastic plate cannot contact the magnesium powder at this time, the magnesium powder attached to the elastic plate can be shaken off during the vibration process, so that the magnesium powder is mixed more evenly.

[0019] Preferably, a connecting plate corresponding to each elastic plate is fixedly connected inside the mounting tube, a connecting rod passes through the connecting plate, and an end of the connecting rod facing away from the elastic plate is fixedly connected to a mounting seat, and a spring is connected between the mounting seat and the connecting plate.

[0020] Preferably, a mounting disk is coaxially arranged inside the mounting cylinder, and the driving member includes a mounting rod and a U-shaped driving seat. The mounting rod is hinged to the corresponding mounting seat, and a torsion spring is arranged at the hinge. The driving seat is evenly arranged at circumferential intervals along the mounting disk and is fixedly connected to the mounting disk. A limiting structure is arranged between the driving seat and the mounting rod. When the mounting rod rotates with the mounting cylinder until it contacts the driving seat, the driving seat drives the mounting rod to rotate through the limiting structure and moves in a direction close to the center of the mounting cylinder.

[0021] Preferably, the limiting structure includes a limiting groove and a limiting protrusion, the limiting groove is provided on the opposite side walls of the driving seat, the limiting protrusion is arc-shaped and is fixedly connected to the two sides of the mounting rod, and when the mounting rod rotates with the mounting tube until the limiting protrusion enters the limiting groove, the limiting groove drives the mounting rod to rotate and move in a direction close to the center of the mounting tube until the limiting protrusion disengages from the limiting groove.

[0022] Preferably, the mounting disk is rotatably connected to the mounting barrel, and a driving structure for driving the mounting disk to rotate is provided on the reaction barrel, and the rotation direction of the mounting disk is opposite to the rotation direction of the mounting barrel.

[0023] Beneficial effects: The mounting plate and the mounting cylinder rotate in different directions, which speeds up the contact frequency between the driving seat and the mounting rod, thereby increasing the vibration frequency of the elastic plate and further improving the phenomenon of magnesium powder agglomeration.

[0024] Preferably, the drive assembly includes a motor, bevel gear one and bevel gear two, the motor is fixedly connected to the reaction cylinder, bevel gear one is fixedly connected to the output end of the motor, bevel gear two is fixedly connected to the mounting cylinder, the drive structure includes bevel gear three, bevel gear three is fixedly connected to the mounting plate, bevel gear two and bevel gear three are located on both sides of bevel gear one, and are respectively meshed with bevel gear one.

[0025] The beneficial effects of the present invention are:

[0026] (1) The present invention provides a plurality of dividing plates. On the one hand, the magnesium powder in the reaction tube is tumbled and stirred, so that the magnesium powder and the passivating agent are mixed more evenly. On the other hand, since the distances between the end of the dividing plate away from the mounting tube and the mounting tube are different, each dividing plate will move the magnesium powder at different positions after rotating from the bottom of the reaction tube, and take away part of the magnesium powder and rotate it to the top of the reaction tube, so that the magnesium powder is divided into multiple parts, and the parts are rotated to the top for spraying the passivating agent, thereby avoiding the phenomenon that the magnesium powder is accumulated and cannot be evenly contacted and mixed with the passivating agent.

[0027] (2) The present invention provides a plurality of intercepting tooth plates so that when the intercepting tooth plates pass through the magnesium powder at the bottom, the magnesium powder that has aggregated can be filtered and fished out, and the intercepting tooth plates can throw the fished out agglomerated magnesium powder to the adjacent dividing plate through the force storage member for impact dispersion, thereby improving the uniformity of mixing the magnesium powder and the passivating agent. In addition, the force storage member causes the intercepting tooth plates to impact the adjacent dividing plate, thereby shaking off the magnesium powder attached to the intercepting tooth plates and the dividing plate, so that the attached magnesium powder can also participate in mixing and passivation.

[0039] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0040] like Figures 1 to 9As shown, a magnesium powder heating passivation device of the present invention comprises a reaction tube 1 and a heating mechanism (not shown in the figure) arranged on the reaction tube 1. As an example, the heating mechanism is an electric heating wire arranged on the periphery of the reaction tube 1. The axial direction of the reaction tube 1 is parallel to the horizontal direction, and the axial direction of the reaction tube 1 is defined as the front-back direction. The bottom of the reaction tube 1 is fixedly connected with a support leg 11, and the top is rotatably connected with a cover body 12. A discharge port 13 is provided at the bottom of the reaction tube 1 near the right side, and a door body 14 is provided at the discharge port 13. A spraying mechanism for spraying a passivating agent is connected to the bottom of the cover body 12, and the spraying mechanism comprises a spraying pipe 15 fixedly installed at the bottom of the cover body 12. A spraying hole (not shown in the figure) begins at the bottom of the spraying pipe 15, and a connecting pipe (not shown in the figure) for connecting the spraying pipe 15 and the spray storage tank is provided on the cover body 12.

[0041] like Figures 2 to 4 As shown, a coaxially arranged mounting barrel 2 is rotatably connected in the reaction barrel 1, and a driving assembly for driving the mounting barrel 2 to rotate counterclockwise is arranged at the rear side of the reaction barrel 1. Six dividing plates 21 are evenly arranged along the circumference of the mounting barrel 2, and the distance between the ends of the six dividing plates 21 away from the mounting barrel 2 and the mounting barrel 2 gradually decreases along the rotation direction of the mounting barrel 2, and one end of the dividing plates 21 away from the mounting barrel 2 contacts the inner wall of the reaction barrel 1. A stopper plate 22 is extended from the end of the four dividing plates 21 that do not contact the inner wall of the reaction barrel 1 away from the mounting barrel 2, and the stopper plate 22 is located on the side of the dividing plates 21 facing the rotation direction of the mounting barrel 2.

[0042] The distance from one end of the dividing plate 21 away from the mounting cylinder 2 to the mounting cylinder 2 is defined as the length of the dividing plate 21. In the initial state, the space between the shortest dividing plate 21 and the longest dividing plate 21 corresponds to the cover 12 at the top of the reaction cylinder 1. Magnesium powder is added from the top of the reaction cylinder 1 and falls between the shortest dividing plate 21 and the longest dividing plate 21. The mounting cylinder 2 is driven counterclockwise by the driving component, and the magnesium powder falls to the bottom of the reaction cylinder 1. As the mounting cylinder 2 continues to rotate, the shortest dividing plate 21 moves the magnesium powder at the upper position and takes away part of the magnesium powder during the upward rotation of the dividing plate 21. The stopper on the dividing plate 21 Plate 22 prevents the carried-away magnesium powder from sliding off the dividing plate 21. When the magnesium powder rotates to the top, it contacts the passivator sprayed by the spray pipe 15. The dividing plates 21 of other lengths pass through the bottom of the reaction tube 1 in turn, and move the magnesium powder at the corresponding position. In the process of upward rotation, part of the magnesium powder is carried away, so that the magnesium powder contacts the passivator at the top of the reaction tube 1, thereby dividing the magnesium powder into several portions, which are sprayed with the passivator respectively through the bottom of the spray pipe 15, avoiding the problem of uneven spraying of the passivator caused by the accumulation of magnesium powder. In addition, in the process of rotation of the mounting tube 2, the magnesium powder can be driven to flip, so that the magnesium powder and the passivator are mixed in a shorter time, thereby improving the passivation efficiency.

[0043] like Figure 2 , Figure 3 and Figure 5 As shown, the mounting cylinder 2 is evenly spaced along its circumference and provided with six interception tooth plates 3, and the interception tooth plates 3 are located on the side of the corresponding material dividing plate 21 away from the rotation direction of the mounting cylinder 2. The interception tooth plate 3 includes a mounting plate 31 and an interception rod 32 evenly spaced along the axial direction of the mounting cylinder 2 and arranged on the mounting plate 31, and a movable rod 33 is elastically connected to one end of the interception rod 32 away from the mounting plate 31, and the mounting plate 31 is rotatably connected to the mounting cylinder 2, and a force storage member 34 is provided at the rotation connection, and as an example, the force storage member 34 is a torsion spring.

[0044] The reaction tube 1 is provided with a guide structure, which includes a guide bar 4 arranged at the bottom of the inner circumferential surface of the reaction tube 1, and an inclined guide surface (not shown in the figure) is arranged at one end of the guide bar 4 away from the rotation direction of the installation tube 2. A limit rod 35 corresponding to the position of the guide bar 4 is fixedly connected to the installation plate 31. During the rotation of the installation tube 2, when the limit rod 35 contacts the guide surface of the guide bar 4, the installation plate 31 and the intercepting rod 32 are driven to rotate relative to the installation tube 2 under the push of the guide bar 4. During the rotation, the force storage member 34 stores force. As the installation tube 2 continues to rotate, the limit rod 35 moves along the guide bar 4, and the movable rod 33 at the end of the intercepting rod 32 is always in contact with the inner wall of the reaction tube 1. The intercepting rod 32 and the movable rod 33 screen the agglomerates in the magnesium powder at the bottom of the reaction tube 1, and pick the agglomerates out of the magnesium powder at the bottom. When the limit rod 35 is disengaged After the guide bar 4, driven by the force storage member 34, the mounting plate 31 drives the interception rod 32 to rotate and reset quickly, thereby throwing the picked-up magnesium powder agglomerates to the adjacent dividing plate 21, causing the magnesium powder agglomerates to collide with the dividing plate 21 and disperse. The magnesium powder after the collision falls to the next dividing plate 21 through the gap between the interception rods 32, and as the mounting cylinder 2 continues to rotate, it moves to the top of the reaction cylinder 1 to contact the sprayed passivating agent, thereby achieving the dispersion of the magnesium powder agglomerates, further improving the uniformity of the mixing of magnesium powder and passivating agent, and improving the passivation effect of magnesium powder. Moreover, when the interception tooth plate 3 is reset, the interception tooth plate 3 will collide with the corresponding dividing plate 21, so that the magnesium powder attached to the interception tooth plate 3 and the dividing plate 21 will be separated.

[0045] like Figure 3 , Figure 4 and Figure 6As shown, the installation tube 2 is provided with six installation grooves 23 evenly spaced along its circumference, and an elastic plate 5 is fixedly connected in the installation groove 23, and the elastic plate 5 is adapted to the notch of the installation groove 23. As an example, the elastic plate 5 is a thin metal plate with elastic deformation ability. A connecting rod 6 is fixedly connected to the side of the elastic plate 5 facing the inside of the installation tube 2, and a connecting plate 24 corresponding to each elastic plate 5 is fixedly connected inside the installation tube 2. The connecting rod 6 passes through the corresponding connecting plate 24, and a mounting seat 61 is fixedly connected to the end of the connecting rod 6 away from the elastic plate 5. A spring 62 is connected between the mounting seat 61 and the connecting plate 24, so that the connecting rod 6 is elastically connected to the installation tube 2 along the radial direction of the installation tube 2.

[0046] like Figure 3 , Figures 6 to 8 As shown, a driving member is provided in the installation cylinder 2 to intermittently drive the connecting rod 6 to move toward the center of the installation cylinder 2. The driving member includes a mounting rod 7 and a U-shaped driving seat 8. The mounting rod 7 is hinged with the corresponding mounting seat 61, and a torsion spring (not shown in the figure) is provided at the hinge. A mounting disk 9 is coaxially provided inside the installation cylinder 2, and the mounting disk 9 is rotationally connected to the installation cylinder 2. A driving structure for driving the mounting disk 9 to rotate is provided on the reaction cylinder 1, and the rotation direction of the mounting disk 9 is opposite to the rotation direction of the installation cylinder 2. The driving seat 8 is evenly spaced along the circumference of the mounting disk 9 and is fixedly connected to the mounting disk 9.

[0047] A limiting structure is arranged between the driving seat 8 and the mounting rod 7 , and the limiting structure comprises a limiting groove 81 and a limiting protrusion 71 . The limiting groove 81 is provided on the opposite side walls of the driving seat 8 , and the limiting protrusion 71 is arc-shaped and fixedly connected to the two sides of the mounting rod 7 . When the mounting cylinder 2 and the mounting plate 9 rotate, when the limiting protrusion 71 on the mounting rod 7 enters the limiting groove 81 of the driving seat 8, the limiting groove 81 drives the mounting rod 7 to rotate through the limiting protrusion 71 and drives the connecting rod 6 to move toward the center of the mounting cylinder 2 through the mounting rod 7, so that the connecting rod 6 pulls the corresponding elastic plate 5 toward the direction close to the inside of the mounting cylinder 2 to deform. As the mounting cylinder 2 and the mounting plate 9 continue to rotate, the limiting protrusion 71 escapes from the limiting groove 81 under strong pulling. At the moment when the limiting protrusion 71 escapes, the mounting rod 7 rotates and resets under the action of the torsion spring, and the connecting rod 6 resets under the elastic force of the spring 62. The elastic plate 5 vibrates and returns to its original state under the action of the reset force of the connecting rod 6 and its own elastic deformation force.

[0048] When the elastic plate 5 rotates to the top of the reaction tube 1 and vibrates, it will drive the magnesium powder to vibrate, so that the magnesium powder and the passivator are in more uniform contact and the magnesium powder is prevented from agglomerating again; when the elastic plate 5 rotates to the bottom of the reaction tube 1 and vibrates, since the elastic plate 5 cannot contact the magnesium powder at this time, the magnesium powder attached to the elastic plate 5 can be shaken off during the vibration process, so that the magnesium powder is mixed more evenly.

[0049] In order to increase the vibration frequency of the elastic plate 5, in this embodiment, each elastic plate 5 is fixedly connected to three connecting rods 6 arranged at axial intervals along the mounting tube 2, and three mounting disks 9 are arranged at axial intervals along the mounting tube 2, respectively corresponding to the positions of the three connecting rods 6, the three mounting disks 9 are fixedly connected, and the driving seats 8 on the three mounting disks 9 are staggered to ensure that during the rotation process, only one connecting rod 6 of the three connecting rods 6 connected to one elastic plate 5 is in contact with the driving seat 8 at the same time.

[0050] like Figure 3 and Fig. 9 As shown, the driving assembly includes a motor 10, a bevel gear 1 101 and a bevel gear 2 25, the motor 10 is fixedly connected to the reaction tube 1, the bevel gear 1 101 is fixedly connected to the output end of the motor 10, the bevel gear 2 25 is fixedly connected to the mounting tube 2, the driving structure includes a bevel gear 3 91, the bevel gear 3 91 is fixedly connected to the mounting plate 9, the bevel gear 2 25 and the bevel gear 3 91 are located on both sides of the bevel gear 1 101, and are respectively meshed with the bevel gear 1 101. The motor 10 drives the bevel gear 1 101 to rotate, and the bevel gear 1 101 drives the bevel gear 2 25 and the bevel gear 3 91 to rotate in opposite directions, thereby driving the mounting tube 2 and the mounting plate 9 to rotate in opposite directions.
