DETAILED DESCRIPTION

[0035] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described to better illustrate the principles of the invention and its practical application, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for specific applications.

[0036] Example 1: Use Figures 1-13 A powder metering and feeding device for processing electronic-grade phosphoric acid according to one embodiment of the present invention is described below.

[0037] like Figure 1-Figure 3As shown, a powder metering and feeding device for electronic-grade phosphoric acid processing of the present invention includes a base plate 1, a processing device 2 is fixedly connected to the top of the base plate 1, support legs 3 are evenly arranged on the top of the base plate 1, a storage bin 4 is fixedly connected to the top of the support legs 3, a top cover 5 is fixedly connected to the top of the storage bin 4, a pouring plate 7 is fixedly connected to the outer surface of the storage bin 4, a metering mechanism 9 is fixedly connected to the side of the storage bin 4 away from the pouring plate 7, a stirring mechanism 6 is provided on the inner wall of the storage bin 4, a collecting mechanism 8 is fixedly connected to the inner wall of the top cover 5, an inlet 10 is provided on the side of the processing device 2 close to the metering mechanism 9, and a magnetic plate 11 is fixedly connected to the outer surface of the inlet 10;

[0038] When the device is working, the powder is first placed away from the storage bin 4, and then the stirring mechanism 6 will work to prevent the powder from clumping. At the same time, the powder and the difficult-to-decompose lumps will be brought into the collecting mechanism 8 for further transportation and decomposition. Finally, the powder will enter the processing device 2 through the metering mechanism 9 at a specific weight.

[0039] like Figure 4 As shown, the stirring mechanism 6 includes a support plate 61, the outer surface of the support plate 61 is fixedly connected to a servo motor 62, the output end of the servo motor 62 is fixedly connected to a rotating shaft 63, the outer surface of the rotating shaft 63 is symmetrically provided with a rotating plate 64, the rotating plate 64 is evenly provided with a decomposition port 65, the end of the rotating plate 64 away from the rotating shaft 63 is fixedly connected to a splash arc plate 66, the two ends of the rotating shaft 63 are symmetrically provided with a telescopic spring 67, the end of the telescopic spring 67 away from the rotating shaft 63 is fixedly connected to a support plate 2 68, and the outer surface of the support plate 2 68 is fixedly connected to a scratch plate 69.

[0040] Before the powder raw materials for electronic-grade phosphoric acid processing are poured into the processing device 2, the powder raw materials will first be placed into the storage bin 4 through the pouring plate 7. Due to differences in powder particle size, density, etc., segregation may occur during the feeding process, resulting in the actual added material component ratio not being consistent with the expectation. The servo motor 62 will drive the rotating shaft 63 to rotate, thereby driving the rotating plate 64 to rotate. The rotating plate 64 will drive the raw materials to turn in the storage bin 4, so that the bottom powder will not be pressed and agglomerated due to the gravity of the upper powder. At the same time, the decomposition port 65 will allow powder of normal size to pass through, while the larger or agglomerated powder will be in the process of rotating the rotating plate 64. In the process of passing through the decomposition port 65, the force of the decomposition port 65 that wants to pass through the pipe will break the agglomerates and larger powders, thereby achieving uniform particle size and facilitating subsequent measurement.

[0041] The support plate 61 is fixedly arranged on the outer surface of the storage bin 4, and the inner wall of the scratch plate 69 is slidably connected to the outer surface of the rotating plate 64.

[0042] like Figure 5-Figure 6As shown, the collecting mechanism 8 includes a support plate three 81, the bottom of the support plate three 81 is fixedly connected to a decomposition mechanism 82, the outer surface of the decomposition mechanism 82 is fixedly connected to a discharge mechanism 85, the top of the support plate three 81 is fixedly connected to an arc groove 83, the inner wall of the arc groove 83 is slidably connected to an arc plate 84, sieve holes 87 are evenly arranged on the upper part of the arc plate 84, and one end of the arc plate 84 is fixedly connected to a hanging plate 86.

[0043] When it is the rainy season and there is a lot of moisture in the air, the powder raw materials in the storage bin 4 will clump due to moisture and are not easy to break. The rotation of the splash arc plate 66 on the rotating plate 64 will throw the normal powder and the agglomerated powder together to the top of the collecting mechanism 8 and drop them. The heavier agglomerated powder and normal powder will fall onto the arc plate 84, and the normal powder will fall onto the decomposition mechanism 82 through the drying port on the arc plate 84. The larger agglomerates will collide with the arc plate 84 due to their greater inertia of falling. At the same time, the second rotating shaft 827 at the bottom will drive the knocking plate 828 to slap the drooping plate 86, so that the arc plate 84 will shake left and right along the inner wall of the arc groove 83, thereby producing a sieving effect, so that the agglomerates are further decomposed and reduced.

[0044] like Figure 7-Figure 8 As shown, the decomposition mechanism 82 includes a fixed plate 821, the top of the fixed plate 821 is provided with an inclined surface 822, the top of the inclined surface 822 is evenly provided with a rotating column 823, the outer surface of the rotating column 823 is fixedly connected to a striking plate 824, the outer surface of the fixed plate 821 is fixedly connected to a servo motor 826, the output end of the servo motor 826 is fixedly connected to a rotating shaft 827, the outer surface of the rotating shaft 827 is fixedly connected to a rolling column 829, and the two ends of the rotating shaft 827 are fixedly connected to a knocking plate 828, which will come into contact with the drooping plate 86.

[0045] After the agglomerates and normal powder that have been broken down into small pieces fall onto the inclined surface 822, the small agglomerates will hit the striking plate 824, causing the striking plate 824 to rotate and collide with other small agglomerates. Then, the servo motor 2 826 will drive the rotating shaft 2 827 and the crushing column 829 to rotate, and further crush the small agglomerates and powder, so that all the powder reaches a uniform size.

[0046] The outer surface of the support plate three 81 is fixedly connected to the inner wall of the top cover 5 , and the two ends of the fixing plate one 821 are fixedly connected to the bottom of the support plate three 81 .

[0047] The specific workflow is as follows:

[0048] During operation, before the powder raw materials for electronic-grade phosphoric acid processing are poured into the processing device 2, the powder raw materials will first be placed into the storage bin 4 through the pouring plate 7, and the servo motor 62 will drive the rotating shaft 63 to rotate, thereby driving the rotating plate 64 to rotate, and the rotating plate 64 will drive the raw materials to turn over in the storage bin 4, so that the bottom powder will not be pressed and agglomerated due to the gravity of the upper powder. At the same time, the decomposition port 65 will allow normal-sized powder to pass through, while the larger or agglomerated powder will be in the process of rotating the rotating plate 64. In the process of passing through the decomposition port 65, the force of the decomposition port 65 that wants to pass through the pipe will break the agglomerates and larger powders. The rotation of the splash arc plate 66 on the rotating plate 64 will throw the normal powder and the agglomerated powder together to the top of the collecting mechanism 8 and drop them, and the heavier agglomerated powder will fall down. The fine powder and normal powder will fall onto the curved plate 84, and the normal powder will fall onto the decomposition mechanism 82 through the drying port on the curved plate 84, while the larger agglomerates will collide with the curved plate 84 due to their larger inertia of falling. At the same time, the second rotating shaft 827 at the bottom will drive the knocking plate 828 to slap the drooping plate 86, so that the curved plate 84 will shake left and right along the inner wall of the arc groove 83, thereby producing a sieving effect. After the agglomerates and normal powder that have been decomposed into small pieces fall onto the inclined surface 822, the small agglomerates will hit the knocking plate 824, causing the knocking plate 824 to rotate and collide with other small agglomerates. After that, the second servo motor 826 will drive the second rotating shaft 827 and the crushing column 829 to rotate, and further crush the small agglomerates and powder.

[0049] Example 2: Use Figures 1-13 A powder metering and feeding device for processing electronic-grade phosphoric acid according to one embodiment of the present invention is described below.

[0050] like Figure 9-10 As shown, a powder metering and feeding device for electronic-grade phosphoric acid processing of the present invention, based on Example 1, includes a feeding mechanism 85 comprising a lower slide plate 1 851, the top of the lower slide plate 1 851 is fixedly connected to the outer surface of the fixed plate 1 821, the bottom of the fixed plate 1 821 is fixedly connected to a drooping rod 852, the bottom of the drooping rod 852 is fixedly connected to a protective shell 853, the inner wall of the protective shell 853 is fixedly connected to a servo motor 3 854, the output end of the servo motor 3 854 is fixedly connected to a gear 1 855, the inner wall of the lower slide plate 1 851 is rotatably connected to a rotating shaft 3 857, the bottom of the rotating shaft 3 857 is fixedly connected to a gear 2 856, the gear 1 855 and the gear 2 856 are meshed with each other, the top of the rotating shaft 3 857 is fixedly connected to a graphene 859, the outer surface of the graphene 859 is fixedly connected to a conductive wire 8510, and the outer surface of the rotating shaft 3 857 is fixedly connected to a shoveling plate 858.

[0051] Powder may generate static electricity during the flow and transportation process. The accumulation of static electricity may cause the powder to adhere to the inner wall of the equipment. After the raw materials are crushed into smaller powder, the powder itself will also carry static electricity due to the previous stirring and crushing, making the powder particularly easy to adhere to the lower slide plate 851. The servo motor 3 854 will drive the gear 1 855 to rotate, and then drive the gear 2 856 to rotate together, and finally drive the shovel plate 858 to rotate, thereby scraping the powder adsorbed on the lower slide plate 1 851 due to static electricity downwards. At the same time, the conductive wire 8510 will introduce the static electricity on the lower slide plate 1 851 into the graphene 859, further allowing the powder to enter the subsequent device more smoothly.

[0052] like Figure 11 As shown, the metering mechanism 9 includes a lower slide plate 91, a flow outlet 92 is provided at the bottom of the lower slide plate 91, a fixed plate 93 is symmetrically provided at the bottom of the lower slide plate 91, a weighing mechanism 94 is rotatably connected to the opposite surface of the lower slide plate 91, and a battery block 95 is fixedly connected to the outer surface of the storage bin 4.

[0053] like Figure 12 As shown, the weighing mechanism 94 includes a rotating shaft 4 941, the top of the rotating shaft 4 941 is fixedly connected to a pouring mechanism 942, the bottom of the rotating shaft 4 941 is fixedly connected to a support rod 943, the end of the support rod 943 away from the rotating shaft 4 941 is fixedly connected to a permanent magnetic plate 944, the outer surface of the fixed plate 2 93 is fixedly connected to the support plate 4 945, the outer surface of the support plate 4 945 is fixedly connected to an electromagnetic block 946, the bottom of the electromagnetic block 946 is fixedly connected to a wire 947, the end of the wire 947 away from the electromagnetic block 946 is fixedly connected to the outer surface of the battery block 95, the top of the constant magnetic plate 944 is fixedly connected to a support column 948, the top of the support column 948 is fixedly connected to a locking plate 949, and the outer surface of the locking plate 949 is slidably connected to the inner wall of the lower slide 2 91.

[0054] The powder will enter the lower slide plate 91 and fall from the outflow port 92 to the pouring plate 9421. At the beginning, the current of the battery panel to the electromagnetic block 946 will be set to control the attraction of the electromagnetic block 946 to the constant magnetic plate 944. When a certain weight of powder enters the pouring plate 9421, the gravity is greater than the magnetic adsorption effect, which will cause the rotating shaft 941 to rotate, thereby causing the pouring plate 9421 to rotate downward, thereby controlling the amount of powder entering the processing device 2.

[0055] like Figure 13As shown, the pouring mechanism 942 includes a pouring plate 9421, the outer surface of the pouring plate 9421 is fixedly connected to the impact rod 9422, the inner wall of the pouring plate 9421 is symmetrically provided with a guide rod 9423, the outer surface of the guide rod 9423 is slidably connected to the shoveling plate 9424, the outer surface of the shoveling plate 9424 is fixedly connected to the magnetic plate 9425, and the bottom of the shoveling plate 9424 is in contact with the bottom of the pouring plate 9421.

[0056] After the pouring plate 7 approaches the entrance 10, the magnetic plate 1 11 will attract the magnetic plate 2 9425, causing the scooping plate 9424 to slide downward along the guide rod 9423. When it moves to the end, the scooping plate 9424 will collide with the impact rod 9422, thereby generating vibration to cause the powder on the scooping plate 9424 to fall off, so that all the measured powder falls into the entrance 10.

[0057] The top of the lower slide plate 91 is fixedly connected to the outer surface of the storage bin 4, the two ends of the rotating shaft 941 are rotatably connected to the opposite surfaces of the fixed plate 93, and the bottom of the pouring plate 9421 is fixedly connected to the outer surface of the rotating shaft 941.

[0058] The specific workflow is as follows:

[0059] During operation, the servo motor 3 854 drives the gear 1 855 to rotate, and then drives the gear 2 856 to rotate, and finally drives the shovel plate 858 to rotate, thereby scraping the powder adsorbed on the lower slide 1 851 due to static electricity downwards. At the same time, the conductive wire 8510 will introduce the static electricity on the lower slide 1 851 into the graphene 859, further allowing the powder to enter the subsequent device more smoothly. After that, the powder will enter the lower slide 2 91 and fall from the outflow port 92 to the pouring plate 9421. At the beginning, the current of the battery panel to the electromagnetic block 946 will be set, thereby controlling the electromagnetic block 946 to the constant magnetic plate 94 4 has the attraction of magnetism. When a certain weight of powder enters the pouring plate 9421, the gravity is greater than the magnetic attraction, which will cause the rotating shaft 4 941 to rotate, thereby causing the pouring plate 9421 to rotate downward, thereby controlling the amount of powder entering the processing device 2. After the pouring plate 7 approaches the entry port 10, the magnetic plate 1 11 will attract the magnetic plate 2 9425, causing the shoveling plate 9424 to slide downward along the guide rod 9423. When it moves to the end, the shoveling plate 9424 will collide with the impact rod 9422, thereby generating vibration to cause the powder on the shoveling plate 9424 to fall, thereby causing all the measured powder to fall into the entry port 10.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention.
