Description

Technical Field

[0001] The invention relates to the technical field of samplers, in particular to a powder storage and retrieval machine for copper oxide preparation. Background Art

[0002] Cupric oxide is a divalent copper oxide, black to brownish black powder or granules, with a molar mass of 79.55 g / mol and a density of 6.315 g / cm 3 , decomposes at 1026℃, and is insoluble in water or alcohol. Copper oxide can be used as a catalyst, catalyst carrier, electrode activation material, and rocket propellant; it can be used as a coloring pigment for ceramics, enamel, glass, and artificial gemstones; it can be used as a semiconductor in a variety of fields such as gas sensors, solar cells, photocatalysts, and capacitor electrodes.

[0003] In some applications, copper oxide needs to be mixed with other materials so that the powder is easier to disperse and mix evenly to ensure that the various components can fully interact with each other. Therefore, copper oxide is prepared into powder. At present, copper oxide powder is placed in sealed plastic bags, glass bottles or plastic bottles, and metal cans for sealed storage. However, these storage devices do not have a good access effect when used, and manual quantitative access is required each time. Therefore, there is a large deviation in access. In addition, manual sampling is most prone to hand shaking, which causes powder to spill and cause environmental pollution. In addition, when copper oxide powder is in an existing storage device, it will also produce agglomeration due to static electricity under good environmental conditions, resulting in poor fluidity when used. The current solution to the agglomeration problem is to stir the copper oxide powder manually on a regular basis, but copper oxide powder has certain physical toxicity.

[0032] A circular frame is fixedly connected to the outer surface of the powder storage tank 1, and a cylindrical fixed connection is provided between the bottom surface of the circular frame and the top surface of the support plate 5, which is used to maintain the stability of the powder storage tank 1 above the support plate 5. The materials of the powder storage tank 1, the support plate 8, the feeding pipe 10 and the sealing block 11 are all made of stainless steel, which is convenient for moisture-proof sealing when storing powder materials.

At least four convex strips 26 are fixedly connected to the inner wall of the powder storage tank 1, and the side wall of the shifting rod 20 is movably connected to the surface of the convex strip 26.

[0034] There are four groups of levers 20, each group has three upper, middle and lower ones. The powder storage tank 1 is a cylindrical bottom conical structure. The scraper 21 is set in an L shape that fits the inner wall of the powder storage tank 1. The side of the scraper 21 that fits the inner wall of the powder storage tank 1 is an inclined surface, which is convenient for scraping off the powder. At the same time, the inner wall of the powder storage tank 1 and the surfaces of the lever 20, the scraper 21, the connecting bolt 22, the support spring 23, the fixing block 24, and the torsion spring 25 are coated with an anti-sticking coating to prevent excessive adhesion of the coating on the metal surface. In addition, the torsion spring 25 is connected to the connecting bolt 22, which can In order to better combine with the lever 20, improve the vibration stability, and more conveniently remove the wall-hanging powder, the scraping wall component is set to achieve the effect of scraping off the wall-hanging powder on the inner wall of the powder storage tank 1, avoiding the situation that the powder is attached to the inner wall of the powder storage tank 1 and cannot fall normally under the normal material taking state, thereby achieving the effect of the powder being taken out and used to the greatest extent. In addition, the setting of the convex strip 26, the connecting bolt 22, and the supporting spring 23 can make the scraper 21 have an elastic knocking effect during the scraping process, so that the powder attached to the inner wall of the powder storage tank 1 is scraped and vibrated off.

[0035] By setting up a material taking component and a wall scraping component, the powder in the powder storage tank 1 can be fully taken out. The setting of the wall scraping component can prevent the powder from clumping and adhering to the inner wall of the powder storage tank 1. In conjunction with the material taking component, the residual wall powder in the powder storage tank can be reduced, thereby improving the overall efficiency of the device for taking materials. In addition, the device as a whole can reduce manpower consumption when taking materials.

[0036] A torsion spring 25 is fixedly connected between the connecting bolt 22 and the lever 20 , and the two connecting bolts 22 form an eight-shaped shape.

[0037] Firstly, the setting of the torsion spring 25 can provide elastic support for the figure-eight connecting bolt 22, so that the figure-eight connecting bolt 22 can produce a certain deformation when subjected to external force, thereby playing a role of buffering and shock absorption, and facilitating the reset support. Secondly, connecting the connecting bolt 22 through the torsion spring 25 can better combine with the lever 20, thereby increasing the overall stability and reliability.

[0038] The upper surface of the support plate 5 is fixedly connected to a support frame 28, the outer surface of the support frame 28 is fixedly connected to a symmetrically arranged stabilizing frame 29, the end of the stabilizing frame 29 is rotatably connected to a rotating rod 32, the end of the rotating shaft 30 and the end of the rotating rod 32 are both fixedly connected to a bevel gear 31, the two bevel gears 31 are meshingly connected, the top end of the rotating rod 32 and the top end of the stirring rod 19 are both rotatably connected to a pulley 33, and a belt body 34 is transmission-connected between the two pulleys 33.

[0039] The bevel gear 31 is used to mesh the rotating shaft 30 and the rotating rod 32, which can make the meshing tighter, improve the transmission efficiency, reduce energy loss, and at the same time be able to withstand larger torque and axial load. In conjunction with the setting of the support frame 28 and the stabilizing frame 29, the overall driving force can be more stable when used.

[0040] The outer surfaces of the top ends of the stirring rod 19 and the rotating rod 32 , as well as the inside of the supporting plate 5 and the end of the stabilizing frame 29 are all fixedly connected with bearings 17 .

[0041] By providing the bearing 17 as the top outer surface of the stirring rod 19 and the rotating rod 32, as well as the interior of the support plate 5 and the rotating fixing part of the end of the stabilizing frame 29, the problem of excessive wear of the stirring rod 19, the threaded rod 18, the stabilizing frame 29 and the rotating rod 32 can be avoided.

[0042] The shape of the stopper 27 is L-shaped.

[0043] By setting the abutment plate 27 to be L-shaped, it can be conveniently fixed to the bottom surface of the support plate 5 and has stability in use.

[0044] The above implementation works as follows:

[0045] The initialization steps are as follows:

[0046] The staff will remove the sealing plug 202 and store copper oxide powder in the powder storage tank 1, and then insert the sealing plug 202 back into the feeding port 201, keeping the sealing cover 2 in a sealed state for the top of the powder storage tank 1. At the same time, the support plate 8 in a sealed state is attached to the bottom surface of the baffle plate 4, and a part of the powder will enter the feeding pipe 10 along with the fluidity of the powder. Then the powder storage tank 1 remains in the storage state, and the sealing block 11 is attached to the surface of the abutment plate 27 to seal the feeding pipe 10.

[0047] The working steps are as follows:

[0048] When there is no need to take out the material, the fluidity of the powder material inside the powder storage tank 1 is maintained to avoid agglomeration, and the double-headed motor 16 can be driven by the staff at regular intervals;

[0049] When there is no need to take materials, the double-headed motor 16 is adjusted by the staff to a one-way rotation state, so that only the rotating shaft 30 rotates;

[0050] The rotation of the rotating shaft 30 can make the two bevel gears 31 mesh, and then the rotating rod 32 rotates at the ends of the two stabilizing frames 29 to maintain stability. When the rotating rod 32 rotates, the pulley 33 acts on the belt body 34, thereby rotating the stirring rod 19. When the stirring rod 19 rotates, the levers 20 arranged at the top, middle and bottom stir the inner wall of the powder storage tank 1 to break the agglomeration of the powder and keep it in a loose state, which is convenient for the fluidity of the subsequent powder taking.

[0051] When it is necessary to take the material, the staff adjusts the double-headed motor 16 to a state where the threaded rod 18 and the rotating shaft 30 rotate together, and then places the material taking container under the opening of the guide port 7;

[0052] When the threaded rod 18 rotates, the outer surface of the threaded rod 18 is fixedly connected to the inner wall of the bearing 17, so the bearing 17 maintains the rotation stability of the threaded rod 18, and then the threaded sleeve 14 and the threaded rod 18 have a thread transmission force. At the same time, the threaded sleeve 14, the slider 15, and the support plate 8 will all limit the thread transmission direction of the threaded sleeve 14 by guiding action, so that the support plate 8 can slide horizontally on the inner wall of the guide port 7. When the support plate 8 slides on the inner wall of the guide port 7, the top surface of the support plate 8 and the bottom surface of the discharge pipe 3 will gradually separate, and then the bottom surface of the sealing block 11 will also gradually separate from the surface of the abutment plate 27. When the discharge port 9 on the surface of the support plate 8 is completely not connected to the discharge pipe 3, the surface of the support plate 8 away from the discharge port 9 will block the bottom of the discharge pipe 3 to prevent the remaining powder from falling, while improving the sealing during the material taking process. At this time, the sealing block 11 will also separate The sealing block 11 will be unable to close at the bottom of the feeding tube 10 due to the gravity of the falling powder, and the sealing block 11 will be turned downward with the hinge block 12 as the intersection point. At this time, the powder stored in the feeding tube 10 will directly fall into the feeding container, and then the staff will drive the double-headed motor 16 to turn the threaded rod 18 again to let the support plate 8 return to a distant place. During the process, the opened and closed sealing block 11 will contact the side wall of the plate 27, and then the sealing block 11 will be closed again on the bottom surface of the feeding tube 10, so that the powder in the powder storage tank 1 can be fully taken out, and the powder on the inner wall of the powder storage tank 1 can be prevented from caking and adhering. With the feeding assembly, the residual wall powder in the powder storage tank 1 can be reduced, thereby improving the efficiency of the overall device for feeding. In addition, when the device as a whole is taking materials, it can reduce manpower consumption and facilitate quantitative feeding.

[0053] As the threaded rod 18 rotates, the rotating shaft 30 rotates, and the rotation of the rotating shaft 30 can make the two bevel gears 31 mesh, and then the rotating rod 32 rotates again at the end of the stabilizing frame 29, so that the two pulleys 33 are transmitted to the two ends of the belt body 34, so that the stirring rod 19 brings the lever 20 to stir the powder material, and at the same time, the side of the scraper 21 away from the stirring rod 19 scrapes the inner wall of the powder storage tank 1, so that the part of the material level line of the powder storage tank 1 that moves downward is scraped off the powder material, and whenever the scraper 21 scrapes the inner wall of the powder storage tank 1 to form a moving trajectory, it will come into contact with the convex strip 26. When it comes into contact with the convex strip 26 , the scraper 21 will be pushed by the convex strip 26; then the supporting spring 23 between the connecting bolt 22 and the fixing block 24 will be deformed in the thrust direction, and then after the scraper 21 as a whole passes over the surface of the convex strip 26, the torsion spring 25 will support the connecting bolt 22 to rebound and reset, and then the supporting spring 23 will also reset, and then the scraper 21 will vibrate and knock on the inner wall of the powder storage tank 1 under the action of elasticity, achieving the effect of scraping and vibrating at the same time, so as to improve the efficiency of material collection, avoid the situation where the material level line moves down and hangs on the wall too much, and also achieve the effect of stirring the powder to improve fluidity during the material collection process.
