DETAILED DESCRIPTION

[0008] like Figure 1 As shown, this embodiment provides an integrated grain grinding and impurity removal device, including an impurity removal device 2 and a grinding device 1 arranged at the bottom of the impurity removal device 2, the discharge port of the impurity removal device 2 is connected to the feed port of the grinding device 1, and the grinding device 1 is a conventional device, so its structure is not specifically shown in the figure.

[0009] Specifically, Figure 1 , Figure 5 As shown, the impurity removal device 2 includes a first barrel 21, a second barrel 22, a power assembly 23 and a stirring assembly. The bottom of the first barrel 21 is connected to the second barrel 22. The inner diameter of the first barrel 21 is larger than the inner diameter of the second barrel 22. The stirring assembly includes a stirring paddle 24 and a rotating rod 25. The power assembly 23 is arranged in the first barrel 21 and connected to the rotating rod 25 for rotating the stirring assembly. The stirring paddle 24 is arranged in the second barrel 22 for stirring the grains. A plurality of slots are arranged on the top of the stirring paddle 24. A magnetic block 242 is inserted in the slot. The magnetic block 242 is in the shape of a rectangular parallelepiped and is used to adsorb metal impurities to the surface of the stirring paddle 24. The stirring paddle The outer edge of the top of 24 is provided with a circle of edge plate 243. The edge plate 243 shown in the figure is rectangular in shape. In addition, the shape of the edge plate 243 can also be set to other shapes such as circular or elliptical. The top of the stirring paddle 24 is connected to the rotating rod 25 in a detachable manner so that the stirring paddle 24 can be removed regularly to remove the metal impurities adsorbed on its surface. The side wall of the first barrel 21 is provided with a window 211, and the horizontal width of the window 211 is greater than the horizontal width of the stirring paddle 24. The window 211 has two functions. One is to put the grain into the second barrel 22 from the window 211, and the other is to facilitate the installation, disassembly or removal of the stirring paddle 24.

[0010] When in use, grains are put into the second barrel 22 through the window 211; the power component 23 is used to rotate the stirring component, and the stirring paddle 24 stirs the grains in the second barrel 22. During the stirring process, metal impurities are adsorbed on the surface of the stirring paddle 24; after stirring for a period of time, the discharge port of the second barrel 22 is opened, and the grains are put into the grinding device 1 for grinding.

[0011] The specific implementation of the power assembly 23 is as follows: Figure 1 , Figure 2As shown, two convex strips 251 are provided on the outer wall of the rotating rod 25, and the top of the rotating rod 25 is rotatably connected to the top plate of the first barrel 21. The power assembly 23 includes a motor 231 and two meshing bevel gears 232, wherein one bevel gear 232 is sleeved on the outer periphery of the rotating rod 25, and the top of the bevel gear 232 is rotatably connected to the top plate of the first barrel 21. The motor 231 is provided on the outer wall of the first barrel 21, and the output shaft of the motor 231 passes through the first barrel 21 and is connected to the other bevel gear 232.

[0012] The principle of the power assembly 23 rotating the stirring assembly is as follows: the motor 231 is started to cause the two bevel gears 232 to rotate. Since the outer wall of the rotating rod 25 is provided with two convex strips 251, the rotating rod 25 will rotate together with the bevel gears 232 sleeved thereon.

[0013] In order to facilitate installation, disassembly or removal of the stirring paddle 24, it is best to lift the stirring paddle 24 upward to the window 211. To achieve this purpose, the present embodiment adopts the following measures: Figure 1 , Figure 6 As shown, the impurity removal equipment 2 also includes a second lifting rod 5 arranged on the outer wall of the first barrel 21, and a horizontal plate 51 is arranged on the top of the second lifting rod 5. The top of the rotating rod 25 passes through the top plate of the first barrel 21 and is rotatably connected to the horizontal plate 51. Note that the size of the through hole must allow the two convex strips 251 to pass through. The rotating rod 25 and the bevel gear 232 mounted thereon are not fixedly connected. The rotating rod 25 and the two convex strips 251 can slide up and down. The power source of the second lifting rod 5 is driven by an oil cylinder or an air cylinder. When it is necessary to provide a stirring component upward, the motor 231 is stopped and the rotating rod 25 can be lifted by the second lifting rod 5.

[0014] In order to reduce dust and make the exterior of the device more neat and beautiful, Figure 1 , Figure 6 As shown, the impurity removal device 2 also includes an arc door 6, which is made of a transparent material, such as glass. The arc door 6 covers the window 211, and the inner wall of the arc door 6 is close to the outer wall of the first barrel 21. A support plate 61 is provided on the top of the arc door 6, and the support plate 61 is connected to the horizontal plate 51. In this scheme, the arc door 6 is arranged to close the window 211, so the grain is no longer fed through the window 211, but an additional feeding port is provided on the outer wall of the first barrel 21 for feeding the grain.

[0015] When it is necessary to remove the metal impurities adsorbed on the surface of the stirring paddle 24, the specific operation is as follows: use the second lifting rod 5 to lift the stirring paddle 24 upward to the window 211. During this process, the arc door 6 also moves upward and exposes the window 211, so that the staff can disassemble and remove the stirring paddle 24; then the staff pulls up the pull ring 244 on the top of the magnetic block 242 by hand to remove the magnetic block 242 in the stirring paddle 24. During this process, the metal impurities on the surface of the stirring paddle 24 fall off and are separated from the stirring paddle 24. Some metal impurities are blocked by the plate 243 and will eventually fall off. Finally, the magnetic block 242 is inserted into the stirring paddle 24 again for the next use.

[0016] In order to more quickly realize the installation or removal of the stirring paddle 24, the stirring paddle 24 and the rotating rod 25 in this embodiment are specifically connected as follows: Figure 3-Figure 5 As shown, the stirring assembly also includes a sleeve 26, a screw 252 and a smooth rod 253 are sequentially provided at the bottom of the rotating rod 25, a T-shaped slot is provided on the side wall of the smooth rod 253, a T-shaped block 245 is provided on the top of the stirring paddle 24, the T-shaped block 245 matches in the T-shaped slot, the inner wall of the sleeve 26 includes a threaded section and a smooth section, the threaded section is threadedly connected to the screw 252, the smooth section is sleeved on the smooth rod 253, the smooth section is used to limit the T-shaped block 245, and the outer wall of the T-shaped block 245 is close to the smooth section of the sleeve 26.

[0017] When the stirring blade 24 needs to be removed, the staff rotates the pipe sleeve 26 by hand to move the pipe sleeve 26 upward. Figure 5 As shown, after the T-block 245 is exposed, the stirring paddle 24 can be directly taken out, which is very convenient to operate.

[0018] In order to improve the stirring effect of the stirring paddle 24, the stirring paddle 24 of this embodiment is specially designed as follows: Figure 5 As shown, the stirring paddle 24 includes a top section, a first vertical section, a bottom section and a second vertical section in sequence, a T-shaped block 245 is arranged at the top section, the bottom section can be straight, the first vertical section and the second vertical section are symmetrically arranged, and a magnetic block 242 is inserted in each of the first vertical section and the second vertical section, and the middle area of ​​the stirring paddle 24 is a through groove. During the stirring process of the stirring paddle 24, the grains can pass through the through groove, which increases the fluidity of the grains. Imagine that if the stirring paddle 24 is plate-shaped and there is no through groove in the middle area, the fluidity of the grains will be affected.

[0019] The discharge port of the impurity removal device 2 is connected to the feed port of the grinding device 1 in the following specific implementation methods: Figure 1 , Figure 3As shown, the impurity removal equipment 2 also includes a third barrel 3 and a first lifting rod 4. The third barrel 3 is arranged at the top of the grinding equipment 1. A through hole is provided on the top of the third barrel 3. The second barrel 22 is provided in the through hole. A support frame 31 is provided in the third barrel 3. The first lifting rod 4 is provided at the top of the support frame 31. A sealing plate 41 is connected to the top of the first lifting rod 4. The bottom of the second barrel 22 is opened. The sealing plate 41 is located in the second barrel 22, and the diameter of the sealing plate 41 is consistent with the inner diameter of the second barrel 22. The power source of the first lifting rod 4 is driven by an oil cylinder or an air cylinder. The first lifting rod 4 is used to adjust the height of the sealing plate 41.

[0020] After the grains are demetallized in the second barrel 22, the first lifting rod 4 moves the sealing plate 41 downward. When the top surface of the sealing plate 41 is lower than the bottom surface of the second barrel 22, a gap appears between the sealing plate 41 and the second barrel 22. The gap is the discharge port of the demetallizing device 2, which is used to release the grains in the second barrel 22 into the feed port of the grinding device 1, and the size of the gap is adjustable.

[0021] More specifically, Figure 3 As shown, the top of the sealing plate 41 is set as a dome, and the bottom section of the stirring paddle 24 is an arc convex upward, and the bottom section of the stirring paddle 24 matches the dome. There are multiple purposes for this design. First, in the stirring and impurity removal process, the dome on the top of the sealing plate 41 is more conducive to improving the fluidity of the grains, thereby improving the stirring and impurity removal effect; second, when the grains in the second barrel 22 are released to the feed port of the grinding device 1, the first lifting rod 4 moves the sealing plate 41 downward, and the gap between the sealing plate 41 and the second barrel 22 is the discharge port of the impurity removal device 2. The dome on the top of the sealing plate 41 is more conducive to the complete release of the grains to the feed port of the grinding device 1, preventing the grains from being deposited on the top of the sealing plate 41.

[0022] In summary, the usage is as follows: The grains are put into the second barrel 22 from the feeding port on the outer wall of the first barrel 21; the motor 231 is started to cause the stirring paddle 24 to rotate, and the stirring paddle 24 adsorbs metal impurities on the surface of the stirring paddle 24 during the stirring and impurity removal process; after the stirring and impurity removal is completed, the first lifting rod 4 moves the sealing plate 41 downward, and the grains in the second barrel 22 are released to the feeding port of the grinding device 1; the grinding device 1 grinds the grains into powder; when the metal impurities on the surface of the stirring paddle 24 accumulate too much and need to be cleaned, the motor 231 is stopped, and the stirring paddle 24 is moved by the second lifting rod 5 The stirring paddle 24 is lifted upward to the window 211. During this process, the arc door 6 also moves upward and exposes the window 211. The staff rotates the sleeve 26 by hand to move the sleeve 26 upward, exposes the T-block 245, and directly takes out the stirring paddle 24. Then the staff pulls up the pull ring 244 on the top of the magnetic block 242 by hand to take out the magnetic block 242 in the stirring paddle 24. During this process, metal impurities on the surface of the stirring paddle 24 fall off, thereby separating from the stirring paddle 24. Finally, the magnetic block 242 is reinserted into the stirring paddle 24 for next use.

It should be understood by those skilled in the art that various changes or equivalent substitutions made to the present invention without departing from the scope of the present invention all fall within the scope of protection of the present invention.
