Description

Technical Field

[0001] This invention relates to the field of zircon powder processing technology, and more particularly to a processing apparatus and method for high-density zircon powder. Background Technology

[0002] Zircon sand is a mineral primarily composed of zircon silicates. As an important rare metal, zirconium possesses excellent properties such as a high melting point, corrosion resistance, plasticity, and unique nuclear properties. It can be used to manufacture glaze materials, refractory materials, glass additives, nuclear fuel cladding, and structural materials, and is widely applied in various industries including ceramics, chemicals, precision casting, aerospace, and nuclear energy. Due to its high toughness and good chemical stability, zircon sand is often used as a surface layer sand in investment casting. Zircon powder is an important industrial raw material, typically obtained by processing zircon sand.

[0003] Currently, with the rapid development of my country's precision casting industry, the demand for zircon sand is continuously increasing. The domestic supply of zircon sand and zircon concentrate is significantly insufficient, requiring substantial reliance on imports. However, under the current international situation, importing zircon sand resources is becoming increasingly difficult, and prices are rising continuously, significantly impacting the development of the domestic precision casting industry. To break the current predicament in the zircon sand market, this invention, based on the characteristics of zircon sand in precision casting processes, develops a composite precision casting sand that can be used as a surface layer sand in investment casting. This aims to alleviate the domestic shortage of zircon sand and the continuous rise in prices. Furthermore, to process the composite precision casting sand into zircon powder, it is necessary to strictly ensure the uniformity of the composite precision casting sand's particle size. Currently, existing technologies cannot control particle size uniformity, which leads to unsatisfactory processing results in subsequent processing and affects the difficulty of impurity removal, resulting in impurity residue and reduced purity. Therefore, this invention is proposed. Summary of the Invention

[0010] Furthermore, the feeding plate is fixedly connected to the inner wall of the baffle and the feeding screening cylinder, and an inclined feeding platform is fixedly connected to the lower outer wall of the feeding plate, the feeding platform corresponding to the position of the feeding hole.

[0011] Furthermore, the magnetic sieve mechanism includes a first auxiliary shaft and a second auxiliary shaft rotatably mounted on two baffles. A cylinder is provided on the outer wall of the first auxiliary shaft. The cylinder is located below the material discharge hole. A layer of iron sheet is wrapped around the outer wall of the cylinder. The discharge plate is located on one side below the cylinder, and the discharge plate does not contact the iron sheet on the cylinder.

[0012] Furthermore, the outer walls of the first auxiliary shaft and the second auxiliary shaft are provided with mutually meshing auxiliary gears, the second auxiliary shaft is also provided with a worm gear, the outer wall of the rotating shaft is provided with a worm gear meshing with the worm gear, the outer wall of the feeding screening cylinder is provided with a discharge port corresponding to the discharge plate, and the baffle is also provided with a slip ring conductive block connected to the first auxiliary shaft.

[0014] The processing method for high-density zircon powder adopts the following steps: Step 1: Each type of sand and gravel is fed into different feeding areas according to different proportions, and then preliminarily screened through the feeding screen; Step 2: The screened sand and gravel will pass through the feed screen and enter the discharge screen in the discharge screening cylinder for secondary shaking and screening; Step 3: The filtered sand and gravel will fall onto the feed plate and then be discharged through the feed hole into the magnetic screen mechanism; Step 4: The magnetic sieve mechanism can filter and screen the iron ore and other substances contained in the sand and gravel.

[0015] Compared with the prior art, the present invention provides a processing apparatus and method for high-density zircon powder, which has the following beneficial effects: 1. This processing device for high-density zircon powder screens different raw materials, resulting in more uniform particle size.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0022] Example 1: Reference Figures 1-10 A processing apparatus for high-density zircon powder includes a feeding screen cylinder 1 and a feed screen cylinder 2 connected to each other. It also includes: a feed screen 203, fixedly installed inside the feed screen cylinder 2; multiple partitions 201 are provided inside the feed screen cylinder 2, dividing the feed screen cylinder 2 into multiple feeding zones 202; two baffles 101 are also provided, fixedly installed inside the feeding screen cylinder 1; an inclined feeding screen 4 is included, slidably disposed between the two baffles 101; an inclined feeding plate 404 is provided at the bottom of the feeding screen 4, and the feeding plate 404 has a feeding hole 405; a magnetic screening mechanism is also provided inside the feed screen cylinder 2, located below the feeding hole 405; and a discharge plate 503 corresponding to the magnetic screening mechanism is provided inside the feed screen cylinder 2.

[0023] In this application, the composite casting sand is first injected into the feeding screening cylinder 2. It should be noted that the composite casting sand is not a single type of sand, but a general term for a mixture of various sands to replace zircon sand, including corundum sand and fused silica sand, and a small amount of zircon sand can be added. Then, each type of sand is fed into different feeding zones 202 according to different proportions, which can achieve the effect of separate feeding and avoid the effect of screening due to different types of sand. Then, it is preliminarily screened through the feeding screen 203, thereby screening out large sand impurities or agglomerates. This process can better control the uniformity and particle size of each raw material at the source. Screening can remove large particles, agglomerates and particles that do not conform to the target particle size range that are originally present in the raw materials, laying the foundation for subsequent precise mixing and helping to ensure the stability of the performance of the mixed product.

[0024] The screened sand and gravel pass through the feed screen 203 into the discharge screen cylinder 1. Therefore, the feed screen 203 can screen different sand and gravel into uniform particle sizes. The sand and gravel then fall onto the inclined discharge screen 4, which can move up and down to create a shaking effect, thus screening the sand and gravel again. This secondary filtration removes larger sand and gravel impurities, helping to further optimize the particle size distribution of the mixed sand and make it more in line with the particle size requirements of the target product, thereby improving product quality. The filtered sand and gravel fall onto the discharge plate 404 and are then discharged through the discharge hole 405 into the magnetic screening mechanism. The magnetic screening mechanism can filter and screen substances such as iron ore contained in the sand and gravel. This step can significantly improve the appearance quality of the product, making the ceramic products produced later uniform in color and beautiful. At the same time, it enhances the physical properties of the product and ensures that the products produced later meet the corresponding high-standard quality requirements.

[0025] It should be noted that the refractories for zircon sand used as surface sand must have a refractoriness of around 1700℃. Secondly, surface sand has high requirements for particle size distribution; currently, the commonly used requirement for zircon sand is 80-120 mesh. Only by meeting these two standards can the applicable requirements for surface sand be met and the quality of the final casting be guaranteed. With the transformation and upgrading of my country's manufacturing industry and the rapid development of the domestic precision casting industry, the demand for high-quality surface sand and powder in the precision casting field is continuously increasing. The high-density zircon powder processing device developed in this application can effectively screen sand and gravel raw materials, ensuring uniform particle size. This allows the processed zircon powder to effectively replace zircon sand in the investment casting process as a shell-making surface sand, not only solving the zircon sand supply problem but also reducing overall costs.

[0026] Secondly, in actual use, this application can also be used to screen single zircon sand or other sand and gravel. In this case, any one of the feeding zones 202 can be selected for feeding, or multiple feeding zones 202 can be used for uniform feeding.

[0027] Example 2: Reference Figures 1-5 and Figure 9 The processing device for high-density zircon powder is basically the same as that in Embodiment 1. Furthermore, the feeding screen 203 is provided with an annular box 204, and the annular box 204 and the feeding screen cylinder 1 are rotatably provided with a rotating shaft 102. The multiple partitions 201 are fixedly connected to the annular box 204.

[0028] A stirring rod 303 is rotatably connected to the annular box 204 and the feeding screening cylinder 2. A toggle rod 305 is provided on the outer wall of the stirring rod 303. A small gear 304 is provided at one end of the stirring rod 303 inside the annular box 204. A disc 3 is fixedly connected to the outer wall of the rotating shaft 102. An annular plate 301 is provided on the disc 3. Gear teeth 302 that mesh with the small gear 304 are provided on the annular plate 301.

[0029] In this embodiment, an external drive power supply (not shown in the figure) is provided on the top of the annular housing 204. This drive power supply can be a stepper motor or a motor, etc. The drive power supply is fixedly installed on the top of the annular housing 204 and is used to drive the rotating shaft 102 to rotate. When the rotating shaft 102 rotates, it first drives the disk 3 fixedly connected to the outer wall of the rotating shaft 102 to rotate, thereby causing the annular plate 301 and the gear teeth 302 set on the disk 3 to start rotating. When the gear teeth 302 contact the pinion 304, they will... The meshing of the pinion 304 causes it to rotate, which in turn drives the stirring rod 303 to rotate the agitator rod 305. The agitator rod 305 agitates the raw material inside the feeding zone 202, allowing the raw material to pass through the feeding screen 203 more effectively and fall down, thus improving work efficiency. It should be noted that the number of gear teeth 302 on the annular plate 301 can be adjusted arbitrarily according to the application. As the number of gear teeth 302 increases, the frequency at which the stirring rod 303 can rotate will also increase.

[0030] Reference Figure 5 A screening shaft 306 is rotatably connected to the outer wall of the rotating shaft 102. Two rollers 307 are provided on the screening shaft 306. A screening brush 308 is provided on the outer wall of the screening shaft 306. Two annular slides 205 are provided at the bottom of the feed screen 203. The two rollers 307 are respectively connected in the two annular slides 205.

[0031] In this application, while the rotating shaft 102 rotates, it also drives the screening shaft 306 connected to the rotating shaft 102 to start rotating. At the same time, the roller 307 located on the screening shaft 306 slides and rotates in the annular slide 205. Since the screening shaft 306 and the rotating shaft 102 are rotatably connected, the roller 307 will drive the screening shaft 306 to rotate synchronously when it rotates, thereby driving the screening brush 308 to roll at the bottom of the feed screen 203. At this time, the bristles on the screening brush 308 will form a reverse physical impact on the mesh from below the feed screen 203: on the one hand, it can push out or sweep away coarse particles such as sand and gravel stuck in the mesh, avoiding long-term particle blockage and permanent deformation of the mesh; on the other hand, it can break up the fine powder agglomerates attached to the screen surface or the edge of the mesh, so that qualified particles can pass through the mesh quickly, ensuring that the screening channel is always unobstructed and avoiding the decrease in screening efficiency due to blockage.

[0032] Example 3: Reference Figures 1-3 , Figures 6-8 and Figure 10 The processing device for high-density zircon powder is basically the same as that in Embodiment 2. Furthermore, the bottom of the feeding screen 4 is provided with a toggle block 401, the bottom of the toggle block 401 is inclined, the outer wall of the rotating shaft 102 is provided with a push block 402, the push block 402 cooperates with the bottom of the toggle block 401, the inside of the feeding screening cylinder 1 is provided with a plurality of support blocks 403, the support blocks 403 are provided at the bottom of the feeding screen 4, and the feeding screen 4 is slidably disposed on the outer wall of the rotating shaft 102.

[0033] The feeding plate 404 is fixedly connected to the inner wall of the baffle 101 and the feeding screening cylinder 1. An inclined feeding platform 406 is fixedly connected to the outer wall of the lower end of the feeding plate 404. The feeding platform 406 corresponds to the position of the feeding hole 405.

[0034] In this embodiment, an external drive power supply (not shown in the figure) is provided on the top of the annular housing 204. This drive power supply can be a stepper motor or a motor, etc. The drive power supply is fixedly installed on the top of the annular housing 204 and is used to drive the rotating shaft 102 to rotate. When the rotating shaft 102 rotates, it can not only drive the disc 3 and the screening shaft 306 to rotate, but also drive the circular block 402 connected to the outer wall of the rotating shaft 102 to rotate. When the circular block 402 rotates, it will gradually cooperate with the inclined surface at the bottom of the actuating block 401. At this time, since the position of the circular block 402 is fixed, when it contacts the inclined surface, it can push the actuating block 401 to move, thereby driving the feeding screen 4 to move. When the circular block 402 finishes cooperating with the inclined surface, the circular block 402... 02 does not contact the actuating block 401. At this time, under the action of gravity, the feeding screen 4 will move downward and reset again, so that the feeding screen 4 can realize the cyclic reciprocating shaking action, thereby shaking the sand and gravel raw materials falling on the feeding screen 4 for further screening and improving screening efficiency. The actuating block 401 is set at a small height, which can only make the feeding screen 4 reciprocate for a short distance, ensuring the stability of the feeding screen 4. The raw materials after secondary screening will fall onto the inclined feeding plate 404, and then fall through the feeding hole 405 into the magnetic screening mechanism for the next step of operation. The feeding platform 406 can realize the limiting effect, so that the sand and gravel raw materials can fall better from the feeding hole 405.

[0035] It should be noted that there is an outlet on the outer wall of the feeding screening cylinder 1 that corresponds to the feeding screen 4. During use, this outlet is blocked by a sealing block and is in a closed state. When the work is finished, the sealing block is removed, and the unscreened sand and gravel raw materials on the feeding screen 4 will be discharged through this outlet. Since this is a secondary screening, the amount of sand and gravel raw materials screened out will not be much. When the sealing block is closed, it will not cause the unscreened sand and gravel raw materials to clog the feeding screen 4.

[0036] The magnetic sieve mechanism includes a first auxiliary shaft 5 and a second auxiliary shaft 504 rotatably mounted on two baffles 101. A cylinder 501 is provided on the outer wall of the first auxiliary shaft 5. The cylinder 501 is located below the discharge hole 405. A layer of iron sheet 502 is wrapped around the outer wall of the cylinder 501. The discharge plate 503 is located on one side below the cylinder 501, and the discharge plate 503 does not contact the iron sheet 502 on the cylinder 501.

[0037] The outer walls of the first auxiliary shaft 5 and the second auxiliary shaft 504 are provided with mutually meshing auxiliary gears 507. The second auxiliary shaft 504 is also provided with a worm gear 505. The outer wall of the rotating shaft 102 is provided with a worm 506 that meshes with the worm gear 505. The outer wall of the feeding screening cylinder 1 is provided with a discharge port 509 corresponding to the discharge plate 503. The baffle 101 is also provided with a slip ring conductive block 508 connected to the first auxiliary shaft 5.

[0038] In this embodiment, the raw material falling through the feeding hole 405 will fall onto the surface of the iron sheet 502 on the cylinder 501. At this time, current is passed through the slip ring conductive block 508 to the iron sheet 502, and iron sand and other materials will be attracted to the surface of the iron sheet 502 under the action of magnetism. Other raw materials will move along the surface of the iron sheet 502 to the discharge plate 503, and then be discharged through the discharge port 509, thereby achieving the effect of screening out the iron sand.

[0039] In this part, the rotational force of the cylinder 501 also comes from the rotating shaft 102. Specifically, when the rotating shaft 102 rotates, it will drive the worm 506 connected to the rotating shaft 102 to rotate, which in turn drives the worm wheel 505 meshing with it to rotate. The worm wheel 505 drives the second auxiliary shaft 504 to rotate, and then through the meshing auxiliary gear 507, it can drive the first auxiliary shaft 5 to rotate, thereby driving the cylinder 501 to rotate, realizing the operation of the magnetic sieve mechanism.

[0040] In this application, the slip ring conductive block 508 adopts the prior art. The slip ring conductive block 508 consists of a fixed part (stator) and a rotating part (rotor). The stator is connected to an external power source, and the rotor is electrically connected to the iron sheet 502 on the cylinder 501. When the cylinder 501 rotates, the rotor rotates with the cylinder 501, and the current can be continuously transmitted from the stator to the rotor, and then passed into the iron sheet 502 on the cylinder 501, so that it generates a magnetic field for magnetic separation of iron materials.

[0041] The baffle 101 is also provided with a limiting plate 6, and the limiting plate 6 is provided with a scraping brush 601 that contacts the sheet metal 502. The bottom of the feeding screening cylinder 1 is provided with a box body 104 and a support rod 107. The bottom of the box body 104 and the support rod 107 is provided with a bottom plate 106. The box body 104 is provided with a drawer box 105. The bottom of the feeding screening cylinder 1 is provided with a through hole 103 that communicates with the box body 104. The through hole 103 corresponds to the position of the limiting plate 6.

[0042] In this application, when the cylinder 501 rotates, the scraping brush 601 can separate the iron sand and other materials on the iron sheet 502, so that they can enter the box 104 through the through hole 103. By taking out the drawer 105, the iron sand and other materials can be taken out. Moreover, the limiting plate 6 is set to be relatively wide, so when the iron sand and other materials fall, they will first slide through the limiting plate 6 into the through hole 103.

[0043] Example 4: The processing method for high-density zircon powder adopts the following steps: Step 1: Each type of sand and gravel is fed into different feeding areas 202 according to different proportions, and then preliminarily screened through the feeding screen 203; Step 2: The screened sand and gravel will pass through the feed screen 203 and enter the discharge screen 4 inside the discharge screening cylinder 1 for secondary shaking screening; Step 3: The filtered sand and gravel will fall onto the feed plate 404 and then be discharged through the feed hole 405 into the magnetic screen mechanism; Step 4: The magnetic sieve mechanism can filter and screen the iron ore and other substances contained in the sand and gravel.

[0044] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
