[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Embodiment 1

[0029] As Figures 1 to 4 shown, the present invention provides a secondary pulping structure for water - milled glutinous rice flour, including a pulping tank 100 for grinding the water - milled glutinous rice flour raw material. At the upper end of the inner cavity of the pulping tank 100, a first pulping section 200 for primary grinding of the water - milled glutinous rice flour raw material is installed. At the lower end of the first pulping section 200, a second pulping section 300 for re - grinding the raw material after being ground by the first pulping section 200 is arranged. In the middle of the first pulping section 200 and the second pulping section 300, a first filtering section 500 for filtering the raw material is provided. At the bottom of the pulping tank 100, a mixing section 400 for stirring the water - milled glutinous rice flour slurry to prevent precipitation is provided.

[0030] The first pulping section 200 includes a first grinding disc 210 and a second grinding disc 220 for grinding the glutinous rice. The first grinding disc 210 and the second grinding disc 220 are arranged in an upper - lower splicing manner. Inside the first grinding disc 210 and the second grinding disc 220, grinding grooves 221 for grinding the glutinous rice raw material are provided. The second grinding disc 220 is fixedly installed at the upper end of the inner cavity of the pulping tank 100. The first grinding disc 210 is movably installed at the upper end of the second grinding disc 220, and is connected and driven at the center with the drive shaft 110 installed at the upper end of the pulping tank 100. At the upper end of the drive shaft 110, a drive device for driving it is fixedly installed.

[0031] The second pulping section 300 includes a supporting bracket 310 for supporting the materials falling from the upper end. At the upper end of the supporting bracket 310, there is a grinding head 320 that matches the shape of the supporting bracket 310. The grinding head 320 is installed in a matching manner with the supporting bracket 310. At the lower end of the supporting bracket 310, there are second material leakage holes 311 for leaking the ground slurry. Inside the second material leakage holes 311, there are filter sheets 312 fixed for filtering the slurry. The grinding head 320 is fixedly installed at the upper end of the drive shaft 110, and the supporting bracket 310 is installed on the inner wall side of the pulping tank 100.

[0032] When grinding the raw material slurry of water mill glutinous rice flour balls, the raw materials can be put in from the feeding port. Then the raw materials leak into the first pulping section 200, and the drive shaft 110 drives it to rotate and grind. The grinding grooves 221 inside the first grinding disc 210 and the second grinding disc 220 rotate and grind. After the raw materials are preliminarily ground, they flow down from one side and then fall into the second pulping section 300 arranged at the lower end. The supporting bracket 310 and the grinding head 320 cooperate to perform secondary grinding on the flowing-down slurry, which can make the slurry more refined. The ground slurry filters and falls from the filter sheets 312 of the second material leakage holes 311, and is ground and filtered again. Two-stage pulping can make the powder more refined, improve the taste and texture of the glutinous rice flour balls, and make them more delicate and smooth.

[0033] On the upper surface of the first grinding disc 210, there are feeding grooves 211 for feeding distribution. The feeding grooves 211 are arranged in a V shape, and at the upper end, there are evenly arranged first material leakage holes 212 for discharging materials. At the lower end of the second grinding disc 220, there are evenly arranged discharging ports 222 for discharging the ground powder. The discharging ports 222 are connected to each other through annular grooves. Setting the V-shaped feeding grooves 211 can facilitate the upper materials to leak into the first material leakage holes 212, and then the powder can be conveyed into the first grinding disc 210 and the second grinding disc 220, facilitating the falling of materials for the powder grinding operation.

[0034] Embodiment 2

[0035] As Figure 6 shown, the first filtering section 500 includes a circular filter plate 510 for filtering the slurry falling from the upper first pulping section 200. At the upper end of the circular filter plate 510, there is a scraping frame 520 movably installed for scraping the materials at the upper end of the pulping tank 100. The lower end of the scraping frame 520 is attached to and installed on the upper surface of the circular filter plate 510. Outside the circular filter plate 510, there is a fixing ring 540 for supporting the circular filter plate 510. The fixing ring 540 is fixedly installed on the inner wall of the pulping tank 100 through bolts.

[0036] When the material is ground step by step in the first grinding section 200 and the second grinding section 300, the material ground by the first grinding section 200 falls onto the circular filter plate 510 arranged at the upper end of the second grinding section 300, which can filter out larger pulp powder. The finer material flows down. The scraping frame 520 can scrape the material to prevent the circular filter plate 510 from being blocked, facilitating the downward flow of the material, and can filter out the larger powder materials. The small-particle materials fall for re-grinding, avoiding the blockage of the upper end of the second grinding section 300 by large materials and affecting the downward flow of the material.

[0037] The scraping frame 520 is arranged in a curved arc shape and is evenly arranged at the upper end of the circular filter plate 510. The outer end of the scraping frame 520 extends to the upper end of the storage tank 550. When the scraping frame 520 rotates to scrape the material, the arc-shaped scraping frame 520 can block the material that cannot settle at the inner side for rotating scraping. After a certain period of time, the driving shaft 110 can be rotated in the reverse direction to push the upper material to rotate, and push the material that cannot fall downward in the forward rotation direction to the inside of the storage tank 550 opened in the fixing ring 540 of the circular filter plate 510, facilitating the temporary storage of larger materials.

[0038] A storage tank 550 for storing larger materials is arranged inside the fixing ring 540. A discharge pipe for discharging and refluxing is arranged on one side of the storage tank 550. The other end of the discharge pipe is connected to the collection unit 600. The inside of the storage tank 550 is arranged in an inclined manner, and the discharge pipe is connected to the lowest part of the storage tank 550. After the material enters the storage tank 550, it flows to one side and then refluxes through the discharge pipe, enabling the timely recovery and treatment of the material.

[0039] A diversion cover 530 for guiding and blocking the slurry after abrasion by the first filtering section 500 installed at the upper end is arranged at the upper end of the scraping frame 520. The diversion cover 530 is arranged in a frustum shape and is installed upside down at the lower end of the first grinding section 200, which can guide the powder falling from the upper end and facilitate the downward flow of the slurry to the middle of the circular filter plate 510 for convenient filtering operation.

[0040] Embodiment 3

[0041] As Figure 5 shown, the mixing section 400 includes a stirring member 410 for mixing and stirring the slurry to prevent the precipitation of the lower slurry. Multiple groups of stirring members 410 are arranged and are evenly arranged at the upper end of the driving shaft 110. An arc-shaped rod 420 for scraping the bottom of the grinding tank 100 to prevent caking is arranged at the lower end of the stirring member 410, and the arc-shaped rod 420 is arranged in contact with the bottom cavity of the grinding tank 100.

[0042] After flowing to the bottom of the pulping tank 100 under slurry polishing, the stirring member 410 and the arc-shaped rod 420 provided at the lower end rotate and stir the slurry to prevent the slurry from settling and caking, facilitating the normal use of the slurry.

[0043] A discharge hood 430 for re-filtering the slurry is provided in the middle of the arc-shaped rod 420. The bracket on the side of the discharge hood 430 is fixedly connected to the arc-shaped rod 420. The lower end of the discharge hood 430 is connected to the discharge hole. When using the material, the discharge hood 430 provided at the lower end can re-filter the slurry to prevent the caked material from being discharged without being stirred, affecting the use.

[0044] Embodiment 4

[0045] As Figure 7 shown, the collection unit 600 includes an abrasive ring 630 communicating with the discharge pipe. A conical grinding head 640 for matching with the abrasive ring 630 for grinding is provided at the lower end of the abrasive ring 630. The upper end of the abrasive ring 630 is in a closed shape. The lower end of the abrasive ring 630 is matched and installed with the conical grinding head 640. The conical grinding head 640 is driven to rotate by a driving device installed at the lower end. A return pipe 610 for conveying the slurry after re-grinding back to the pulping tank 100 is arranged on one side of the lower end of the housing of the collection unit 600. A liquid supplement pipe 620 for assisting the slurry return and providing an abrasive water source for it is provided on one side of the return pipe 610.

[0046] When the returned material enters the interior of the housing of the collection unit 600, the abrasive ring 630 and the conical grinding head 640 cooperate to simply grind the material, and then it is returned through the return pipe 610 installed on one side. Then, the liquid is supplemented through the liquid supplement pipe 620 and enters the first pulping section 200 again for abrasion, and is processed in a cycle, facilitating the processing.

[0047] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model.
