Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 - 8, in the embodiment of the present utility model, a fine powder machine for preparing konjac powder based on impurity filtration and screening includes a crushing mechanism 10, a metal sieve 20 and a fine grinding mechanism 30. The metal sieve 20 is arranged between the crushing mechanism 10 and the fine grinding mechanism 30. The metal sieve 20 includes a second housing 21 and a plurality of metal collectors 25 arranged inside the second housing 21. There are six metal collectors 25 in this embodiment. A collection groove 213 is formed in the second housing 21. The metal collector 25 includes an inner roller 252 and an outer housing 253. The inner roller 252 is arranged inside the outer housing 253, and the outer housing 253 is rotatably installed in the second housing 21. The inner roller 252 is fixedly installed in the second housing 21, and a magnet area ( Figure 8 the shaded area in) and a non-magnetic area are provided on the inner roller 252. The non-magnetic area faces the side wall of the second housing 21. The crushing mechanism 10 is used to preliminarily crush konjac to obtain konjac crushed material. When the konjac crushed material flows into the inside of the second housing 21, the magnet area on the inner roller 252 adsorbs the metal substances in the konjac crushed material, so that the metal substances adhere to the surface of the outer housing 253. After the crushing is completed, the outer housing 253 rotates, so that the metal substances rotate to the non-magnetic area. After the metal substances lose the magnetic attraction, they are separated from the outer housing 253 and enter the inside of the collection groove 213. Further, in the embodiment of the present application, an arc-shaped groove for accommodating the outer housing 253 is formed in the second housing 21. A scraper 212 is installed on one side of the arc-shaped groove. The scraper 212 is attached to the surface of the outer housing 253. When the outer housing 253 rotates, the scraper 212 scrapes the metal substances on the surface of the outer housing 253, so that the metal substances are quickly separated from the outer housing 253.

[0024] In the embodiment of the present application, a gear ring 26 is rotatably installed on the upper side of the second housing 21. A first toothed part is arranged inside the gear ring 26, and a second toothed part is arranged outside the gear ring 26. A driven gear 251 is installed at the end of the outer housing 253. The driven gear 251 meshes with the first toothed part. A driving gear 27 is also rotatably installed on the second housing 21. The driving gear 27 meshes with the second toothed part. When the gear ring 26 rotates, the first toothed part controls the rotation of the outer housing 253 through the driven gear 251. Further, in the embodiment of the present application, a sealing plate 211 is arranged on the other side of the arc-shaped groove. The sealing plate 211 is slidably installed inside the second housing 21, and an arc-shaped track is arranged on the second housing 21. A first slider 28 and a second slider 29 are slidably installed inside the arc-shaped track. The first slider 28 and the second slider 29 are connected by a spring. The first slider 28 is fixedly connected to the gear ring 26, and the second slider 29 is fixedly connected to the sealing plate 211. When the gear ring 26 rotates, the first slider 28 pushes the second slider 29 to move along the arc-shaped groove, thereby driving the sealing plate 211 to move and retracting the sealing plate 211 into the second housing 21 to avoid the sealing plate 211 contacting the metal substances on the surface of the outer housing 253. In addition, in the embodiment of the present application, an upper cover 22 and a lower cover 23 are respectively arranged on the upper and lower sides of the second housing 21. A second motor 24 is fixedly installed on the upper cover 22. The output end of the second motor 24 is fixedly connected to the driving gear 27.

[0025] In the embodiment of the present application, the crushing mechanism 10 includes a first housing 11 and two crushing rollers 12 rotatably installed inside the first housing 11. A gear box 14 and a first motor 13 are arranged outside the first housing 11. The first motor 13 drives the crushing rollers 12 to rotate through the gear box 14.

[0026] In the embodiment of the present application, the fine grinding mechanism 30 includes a first housing 31 and a fine grinding roller 32 disposed inside the first housing 31. There is a grinding gap between the fine grinding roller 32 and the first housing 31. The fine grinding roller 32 is rotatably installed inside the first housing 31 through a drive shaft 34. When the material passes through the grinding gap, extrusion, shear force, and frictional force are generated between the rotating fine grinding roller 32 and the first housing 31, thereby grinding the material to form fine particles. A vibrating screen 33 is provided at the lower part of the first housing 31. The vibrating screen 33 is slidably installed on the drive shaft 34. A vibrating motor is provided on the vibrating screen 33. A bottom plate is installed on the drive shaft 34. The vibrating screen 33 is connected to the bottom plate through a return spring 36 sleeved outside the drive shaft 34. The vibrating motor and the return spring 36 are used to drive the vibrating screen 33 to vibrate, so that the vibrating screen 33 screens the ground material to discharge the konjac powder meeting the processing requirements through the vibrating screen 33, and the waste materials not meeting the requirements remain on the vibrating screen 33. In addition, a discharge port is opened at the bottom of the first housing 31, and the discharge port is used to discharge the konjac powder. A rotary motor 35 is fixedly installed at the bottom of the first housing 31. The output end of the rotary motor 35 is fixedly connected to the drive shaft 34, and the rotary motor 35 controls the rotation of the fine grinding roller 32 through the drive shaft 34.

[0027] In the embodiment of the present application, a collection mechanism 40 is further included. The collection mechanism 40 includes a second housing 41, a first pipe 44, and a second pipe 45. A first collection chamber 42 and a second collection chamber 43 are opened inside the second housing 41.

One end of the second pipe 45 communicates with the first housing 31, and the other end of the second pipe 45 communicates with the second collection chamber 43. An exhaust port 47 is provided on the outer side of the second housing 41, and the exhaust port 47 is used to connect to a negative pressure pump. A microporous plate 46 is provided between the first collection chamber 42, the second collection chamber 43, and the exhaust port 47. When collecting the metal material and waste materials, the negative pressure pump is started, and the metal material in the collection tank 213 and the waste materials on the vibrating screen 33 enter the first collection chamber 42 and the second collection chamber 43 respectively through the first pipe 44 and the second pipe 45.

[0028] In summary, the present application performs multi-stage crushing on konjac through the crushing mechanism 10 and the fine grinding mechanism 30, processes the konjac into konjac powder with the required particle size, and a metal collector 25 is provided between the crushing mechanism 10 and the fine grinding mechanism 30 to separate and collect the metal impurities during the konjac processing.
