Description
Technical Field
[0001] This utility model belongs to the field of rice production technology, specifically relating to a rice vortex washing and impurity removal separation screen. Background Technology
[0002] Grains are the main source of calories needed by the human body. The world's major grains include rice, wheat, rye, sorghum, corn and millet. China produces all of these grains except rye. The largest production is of rice, wheat, corn and sorghum. Grains other than rice and wheat are usually called coarse grains. The chemical composition of grains varies with variety, soil, climate and cultivation techniques.
[0003] Rice is an indispensable food source for us. During the rice processing, it usually needs to be washed to ensure its cleanliness.
[0004] Currently, rice is usually washed using a mixing drum with a stirring function. While washing, the rice is stirred by a stirring mechanism to prevent the rice from piling up and affecting the tilting effect.
[0005] For example, in the prior art, Chinese utility model patent with authorization announcement number CN222001001U discloses "a washing device for rice processing", which includes a support mechanism, a stirring mechanism, a water spraying mechanism, and a discharge mechanism. The stirring mechanism is located at the top of the support mechanism. Rice is poured into the stirring drum through the rice inlet, water is injected into the water supply pipe through the water inlet, and sprayed into the stirring drum by the nozzle. The stirring motor is started by the controller, which drives the stirring shaft to rotate synchronously, thereby driving the stirring blades to stir and wash the rice, improving the uniformity of rice washing.
[0006] While existing cleaning equipment, including those mentioned above, can meet general cleaning needs, it cannot effectively remove large particles of impurities in rice, such as mud, stones, and rice husks. During the cleaning process, these large particles are discharged along with the rice, requiring secondary screening, which significantly reduces production efficiency.
[0007] To address the aforementioned problems, this utility model proposes a rice vortex washing and impurity removal separation screen. Utility Model Content

[0047] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0048] Please see Figures 1-6 The present invention provides the following technical solution: a rice vortex washing and impurity removal separation screen, including a support platform 1, and further including: a screening box 2 disposed above the support platform 1, a screening mesh plate 3 that is inclined and slidably disposed in the screening box 2, a feeding hopper 4 fixed to the bottom of the screening box 2, two vibrating motors 5 symmetrically disposed on the outer wall of the feeding hopper 4, a washing box 6 fixed on the support platform 1 and penetrating the support platform 1, a washing basket 7 adapted to be installed in the washing box 6 and slidable, and a stirring mechanism 8 disposed at the bottom of the washing box 6.
[0049] Furthermore, by Figure 1 , Figure 3 and Figure 4As shown in this embodiment, the screening box 2 has a first disassembly port 21 for disassembling and assembling the screening screen plate 3, and a discharge port 23 is provided at the corresponding position at the bottom of the screening screen plate 3. The bottom surface of the hopper 4 is provided with diagonally distributed support columns 41. The support columns 41 are elastically connected to the support platform 1 by support springs 42. The washing box 6 is located directly below the hopper 4. The washing box 6 has a second disassembly port 62 for disassembling and assembling the washing basket 7. Its bottom is provided with a drainage flange interface 61. The stirring mechanism 8 is used to form a vortex in the washing box 6. With the above scheme, when in use, rice enters the equipment from the feed port above the screening box 2. Since the screening screen plate 3 is inclined and slidably installed in the screening box 2, and the hopper 4 is connected to the support platform 1 by four diagonally distributed support columns 41, the support springs 42 between the support columns 41 and the support platform 1 play an elastic support role.
[0050] After the two symmetrically fixed vibrating motors 5 on the outer wall of the feeding hopper 4 are started, the vibration energy generated is transmitted to the support spring 42 through the feeding hopper 4, so that the feeding hopper 4 and the screening screen plate 3 form a resonance system.
[0051] Under vibration, larger impurities, such as mud, stones, and rice husks, will slide down the screening screen 3 and be discharged from the discharge port 23 with the vibration, thus achieving preliminary impurity removal.
[0052] Rice particles that meet the size requirements and small impurities continue to pass through the mesh of the screening screen plate 3 and are eventually discharged from the hopper 4. Then, under the action of gravity, they fall into the washing basket 7 in the washing box 6 below.
[0053] At this time, the stirring mechanism 8 installed at the bottom of the washing tank 6 starts to work. The drain flange interface 61 is connected to the sewage pump through a pipe. The stirring mechanism 8 stirs the washing water in the washing tank 6, so that the rice forms a vortex motion in the washing basket 7, so that the washing water fully contacts the surface of the rice and washes away the dust, residual small particles and impurities attached to the surface of the rice.
[0054] After washing is completed, the sewage pump is started. The sewage carrying impurities passes through the mesh of the washing basket 7 and is discharged through the drain flange interface 61 at the bottom of the washing tank 6, while the washed rice remains in the washing basket 7.
[0055] After cleaning, the cleaning basket 7 can be slid out of the cleaning box 6 through the second disassembly port 62 on the cleaning box 6, so as to collect the cleaned rice and complete the entire vortex cleaning and impurity separation process of the rice.
[0056] Optionally, by Figure 1 and Figure 2As shown, in this embodiment, the stirring mechanism 8 includes: a rotating disk 81 rotatably installed in the washing tank 6, a toggle piece 82 circumferentially and uniformly fixed on the top surface of the rotating disk 81, and a drive motor 83 that drives the rotating disk 81 to rotate. The drive motor 83 is fixed to the bottom of the washing tank 6. With the above solution, when rice falls into the washing basket 7, the drive motor 83 is powered on and starts to run. Its output shaft drives the rotating disk 81 to rotate at high speed in the washing tank 6 through a coupling.
[0057] The agitator 82 rotates at high speed, which agitates the washing water, creating a vortex that continuously impacts the rice. This vortex motion washes away dust, residual small particles, and other impurities adhering to the surface of the rice.
[0058] Preferably, by Figure 1 and Figure 3 As shown, this embodiment also includes a detachable connection component, which includes: a first limiting plate 31 fixed to one end of the screening screen plate 3 and a locking bolt 9. A threaded hole 22 is provided on the screening box 2. The locking bolt 9 passes through the first limiting plate 31 and is screwed into the threaded hole 22 by thread engagement. With the above solution, when the screening screen plate 3 is completely pushed into the screening box 2, the first limiting plate 31 is attached to the outer wall of the screening box 2. The locking bolt 9 passes through the first limiting plate 31 and is screwed into the threaded hole 22 by thread engagement. The locking bolt 9 is used to lock the first limiting plate 31 to ensure the stability of the installation of the screening screen plate 3.
[0059] Since the screening screen plate 3 is a sliding installation, when it is necessary to disassemble the screening screen plate 3 for cleaning, first unscrew the locking bolt 9, and then directly slide out the screening screen plate 3, which is easy to clean.
[0060] Preferably, by Figure 1 , Figure 3 and Figure 5 As shown, in this embodiment, it further includes a first handle 32 fixed to the outer wall of the first limiting plate 31. With the above solution, when in use, the first handle 32 makes it easy for the staff to apply force to pull out the screening screen plate 3.
[0061] Preferably, by Figure 1 , Figure 3 and Figure 5 As shown, this embodiment further includes: a U-shaped frame 12 fixed in an inclined position inside the screening box 2, and a support groove 121 adapted to the screening screen plate 3 is provided in the U-shaped frame 12. With the above solution, during use, the installation position of the screening screen plate 3 is positioned by the U-shaped frame 12, and the support groove 121 is used to support the screening screen plate 3, ensuring the stability of the installation of the screening screen plate 3 and avoiding relative collision between the screening screen plate 3 and the screening box 2 during the vibrating screening process.
[0062] Preferably, by Figure 1 and Figure 4 As shown, this embodiment further includes: a second limiting plate 71 fixed to one end of the cleaning basket 7, threaded rods 10 symmetrically hinged to both ends of the cleaning box 6, and a wing nut 11. The second limiting plate 71 has symmetrically distributed positioning blocks 72 fixed at both ends. A positioning notch 721 for the threaded rod 10 to pass through is provided on the positioning block 72. The wing nut 11 is installed on the protruding end of the threaded rod 10 by threaded engagement. With the above scheme, when the cleaning basket 7 is completely pushed into the cleaning box 6, the second limiting plate 71 is attached to the outer wall of the cleaning box 6. Then, the threaded rod 10 is manually rotated until it passes through the positioning notch 721. Finally, the wing nut 11 is tightened. Under the threaded engagement, the wing nut 11 moves closer to the cleaning box 6 and presses the positioning block 72 to lock the cleaning basket 7, ensuring the stability of the cleaning basket 7 installation.
[0063] Preferably, by Figure 1 , Figure 4 and Figure 6 As shown, in this embodiment, it further includes a second handle 73 fixed to the outer wall of the second limiting plate 71. With the above solution, when in use, the second handle 73 makes it easy for the staff to apply force to pull out the cleaning basket 7.
[0064] Preferably, by Figure 1 , Figure 4 and Figure 6 As shown, in this embodiment, it further includes: support bars 13 symmetrically fixed inside the cleaning tank 6 to support the cleaning basket 7, thereby further improving the stability of the installation of the cleaning basket 7.
[0065] It should be noted that the drive motor 83 is a commercially available standard device with a built-in power switch. Those skilled in the art can make conventional selections according to their needs. Its working principle is common knowledge known to those skilled in the art and has been fully disclosed in the prior art, so it will not be elaborated further in this article.

[0067] Components not described in detail in this article are existing technologies.
[0068] The working principle and usage process of this utility model: When using the rice vortex washing and impurity removal separation screen of this utility model, rice enters the equipment from the feed port above the screening box 2. Since the screening screen plate 3 is inclined and slidably installed in the screening box 2, the discharge hopper 4 is connected to the support platform 1 through four diagonally distributed support columns 41. The support spring 42 between the support column 41 and the support platform 1 plays an elastic support role.
[0069] After the two symmetrically fixed vibrating motors 5 on the outer wall of the feeding hopper 4 are started, the vibration energy generated is transmitted to the support spring 42 through the feeding hopper 4, so that the feeding hopper 4 and the screening screen plate 3 form a resonance system;
[0070] Under vibration, larger impurities, such as mud, stones, and rice husks, will slide down the screening screen 3 and be discharged from the discharge port 23 with the vibration, thus achieving preliminary impurity removal.
[0071] Rice particles that meet the size requirements and small impurities continue to pass through the mesh of the screening screen plate 3 and are eventually discharged from the hopper 4. Then, under the action of gravity, they fall into the washing basket 7 in the washing box 6 below.
[0072] At this time, the stirring mechanism 8 installed at the bottom of the washing tank 6 starts to work, the drain flange interface 61 is connected to the sewage pump through the pipe, and the stirring mechanism 8 stirs the washing water in the washing tank 6, so that the rice forms a vortex motion in the washing basket 7, so that the washing water fully contacts the surface of the rice, and washes off the dust, residual small particles and impurities attached to the surface of the rice.
[0073] After washing, the sewage pump is started. The sewage carrying impurities passes through the mesh of the washing basket 7 and is discharged through the drain flange interface 61 at the bottom of the washing tank 6, while the washed rice remains in the washing basket 7.
[0074] After cleaning, the cleaning basket 7 can be slid out of the cleaning box 6 through the second disassembly port 62 on the cleaning box 6, so as to collect the cleaned rice and complete the entire vortex cleaning and impurity separation process of the rice.
[0075] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
