Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of separation screens, in particular to a white rice separation screen. Background Art
[0002] Grading white rice is a crucial step in its processing, and separating whole rice from broken rice by vibrating or sieving is also part of the process. However, a new type of white rice has emerged, with elongated grains that are significantly longer than traditional white rice, while retaining the same thickness.
[0003] In the prior art, whole rice and broken rice are often separated by sieving. Because traditional white rice grains are relatively round, the size of broken rice is significantly different from that of whole rice. Separation can be achieved by controlling the aperture of the sieve. However, after being converted into broken rice, the slender white rice usually loses length while the thickness remains unchanged. As a result, the whole rice can also pass through the aperture that the broken rice can pass through, making it difficult to separate the whole rice and broken rice. Utility Model Content
[0004] The utility model aims to provide a white rice separation screen, which can achieve the separation of whole rice and broken rice by cooperating with a columnar net and a columnar cylinder so that broken rice can pass through the mesh holes of the columnar net normally, while whole rice is stuck in the mesh holes of the columnar net due to its length.
[0005] The utility model provides a white rice separation screen, comprising:
[0006] A screen, comprising a cylindrical net and a cylindrical barrel, wherein the cylindrical net is concentrically assembled in the cylindrical barrel, a gap is left between the outer cylindrical surface of the cylindrical net and the inner cylindrical surface of the cylindrical barrel, and the cylindrical net and the cylindrical barrel are placed horizontally;
[0007] A collector, the collector is located inside the columnar net, and the collecting port of the collector faces upward;
[0008] A loader, wherein the discharge end of the loader is located inside the columnar net and below the collector;
[0009] After the white rice enters the screen, the broken rice passes through the columnar net and enters the gap between the columnar net and the columnar cylinder. The whole rice is blocked by the columnar cylinder and stuck in the mesh of the columnar net. The rotation of the columnar cylinder drives the whole rice to move upward and fall into the collector under the action of gravity.
[0010] Preferably, the columnar net and the columnar barrel are fixedly connected and rotate synchronously, and a discharge trough is provided near both ends of the columnar barrel, and the broken rice is discharged from the screen through the discharge trough.
[0011] Preferably, a dragon baffle is integrally formed on the inner cylindrical surface of the cylindrical tube.
[0012] Preferably, the screen is tilted as a whole, with the side close to the discharge end of the loader tilted upward, and the tilt angle is greater than 5 to 10 degrees.
[0013] Preferably, the collector comprises a guide plate and a conveyor belt, and the guide plate is fixedly assembled along an edge of the conveyor belt.
[0014] Preferably, the discharge end of the feeder is provided with a trimming edge, the size of the discharge end of the feeder changes from large to small at the trimming edge, and the entire section of the trimming edge is located inside the columnar net.
[0015] Preferably, the discharge end of the loader is fixedly connected with a scraper, and the scraper is fixedly connected to the bottom of the discharge end of the loader. The scraper is away from the discharge end of the loader and close to the inner cylindrical surface of the columnar net, and a gap is left between the scraper and the columnar net.
[0016] Preferably, the white rice separation screen further comprises a hair dryer, and the air outlet of the hair dryer faces the screen.
[0017] Preferably, the cylindrical barrel is formed by curling a densely woven mesh, and the blower is located directly above the mesh.
[0018] Preferably, the edges of the columnar mesh holes close to the center are chamfered.
[0019] The technical solution of the present invention realizes the separation of whole rice and broken rice through the cooperation of the columnar net and the columnar cylinder. When the broken rice passes through the columnar net, it escapes from the mesh of the columnar net before it hits the columnar cylinder due to its shorter length, and thus passes through the columnar net smoothly. However, when the whole rice passes through the columnar net, it has not escaped from the mesh of the columnar net when it hits the columnar cylinder due to its longer length, resulting in the whole rice being stuck in the mesh of the columnar net.

[0032] Combine Figures 1 to 6 As shown, the white rice separation screen provided by the present invention includes a screen 1, a collector 2 and a feeder 3.
[0033] Combine Figures 1 to 6 As shown, the screen 1 includes a cylindrical net 11 and a cylindrical barrel 12, the cylindrical net 11 is concentrically assembled in the cylindrical barrel 12, and a gap is left between the outer cylindrical surface of the cylindrical net 11 and the inner cylindrical surface of the cylindrical barrel 12, and the cylindrical net 11 and the cylindrical barrel 12 are placed horizontally; the collector 2 is located inside the cylindrical net 11, and the collecting port of the collector 2 faces upward; the discharge end of the feeder 3 is located inside the cylindrical net 11, and the discharge end of the feeder 3 is located below the collector 2; after the white rice enters the screen 1, the broken rice passes through the cylindrical net 11 and enters the gap between the cylindrical net 11 and the cylindrical barrel 12, and the whole rice is stuck in the mesh of the cylindrical net 11 under the obstruction of the cylindrical barrel 12, and the rotation of the cylindrical barrel 12 drives the whole rice to move upward and falls into the collector 2 under the action of gravity.
[0034] In this embodiment, the separation of whole rice and broken rice is achieved through the cooperation of the cylindrical net 11 and the cylindrical cylinder 12. When the broken rice passes through the cylindrical net 11, it is short in length and has already escaped from the mesh of the cylindrical net 11 before it hits the cylindrical cylinder 12, thereby smoothly passing through the cylindrical net 11; while when the whole rice passes through the cylindrical net 11, it is long in length and has not yet escaped from the mesh of the cylindrical net 11 when it hits the cylindrical cylinder 12, causing the whole rice to be stuck in the mesh of the cylindrical net 11; when the cylindrical cylinder 12 drives the whole rice to move upward, the whole rice stands upside down and falls into the collector 2 under the action of gravity, and the whole rice and broken rice are separated.
[0035] In some embodiments, combined Figure 2As shown, the cylindrical net 11 and the cylindrical barrel 12 are fixedly connected and rotate synchronously. The synchronous rotation can reduce the friction between the rice grains and the cylindrical barrel 12, thereby protecting the rice grains. A discharge trough is provided near both ends of the cylindrical barrel 12, and broken rice is discharged from the screen 1 through the discharge trough to avoid the accumulation of broken rice in the gap and affecting the subsequent separation effect. At the same time, the design of the discharge trough can make the broken rice concentrated at a specific position for discharge, which is convenient for the collection of broken rice.
[0036] In some embodiments, combined Figure 3 As shown, a dragon baffle 13 is integrally formed on the inner cylindrical surface of the cylindrical barrel 12. During the rotation process, the design of the dragon baffle 13 can continuously concentrate the broken rice to one side, thereby accelerating the discharge efficiency of the broken rice.
[0037] In some embodiments, combined Figure 1 、 Figure 2 As shown, the screen 1 is tilted as a whole, and is tilted upward near the discharge end of the feeder 3. The tilt angle is greater than 5 to 10 degrees. The design of the tilt angle increases the fluidity of the rice grains in the screen 1, accelerates the spreading of the rice grains, thereby increasing the contact area between the white rice as a whole and the columnar mesh 11, and increasing the separation efficiency.
[0038] In some embodiments, combined Figure 1 As shown, the collector 2 includes a guide plate and a conveyor belt. The guide plate is fixedly assembled along the edge of the conveyor belt. The falling of whole meters does not occur when it rotates to the highest point. The design of the guide plate can increase the collection efficiency of the collector 2 for whole meters, and finally the whole meters are transported to the designated location through the conveyor belt.
[0039] In some embodiments, combined Figure 4 As shown, the discharge end of the feeder 3 is provided with a cutting edge, and the size of the discharge end of the feeder 3 changes from large to small at the cutting edge, so as to increase the width of the discharge port of the feeder 3, speed up the process of spreading the white rice, and improve the separation efficiency; the entire section of the cutting edge is located inside the columnar net 11, ensuring that all the white rice can eventually be transported to the screen 1 to avoid waste.
[0040] In some embodiments, combined Figure 5 As shown, the discharging end of the loader 3 is fixedly connected to a scraper 31, and the scraper 31 is fixedly connected to the bottom of the discharging end of the loader 3. The scraper 31 is away from the discharging end of the loader 3 and close to the inner cylindrical surface of the columnar net 11. There is a gap between the scraper 31 and the columnar net 11. The scraper 31 can scrape the piles of white rice flat, effectively avoiding the problem of white rice accumulation.
[0041] In some embodiments, combined Figure 1As shown, the white rice separation screen also includes a hair dryer 4, the air outlet of which is directed toward the screen 1. The hair dryer 4 is a commonly used device in the white rice separation process, and is mainly used to blow out impurities mixed into the white rice.
[0042] In some embodiments, combined Figure 1 、 Figure 5 As shown, the cylindrical tube 12 is curled by a densely woven mesh, which prevents the white rice from passing through while ensuring air permeability; other methods can also be used instead, which can prevent the white rice from passing through while ensuring that the wind generated by the hair dryer 4 can pass through smoothly. The hair dryer 4 is located directly above the screen 1, so that the hair dryer 4 can not only blow out impurities mixed in the white rice, but also speed up the process of the white rice falling, and prevent the white rice from getting stuck in the mesh of the cylindrical net 11.
[0043] In some embodiments, combined Figure 6 As shown, the edge of the mesh of the columnar net 11 close to the center is chamfered, which can effectively increase the probability of rice grains entering the mesh and ensure separation efficiency.
[0044] Working process: White rice is transported to the columnar net 11 through the feeder 3; the columnar net 11 rotates, and during the rotation, rice grains continuously enter the mesh of the columnar net 11, broken rice passes through the columnar net 11 and enters the gap between the columnar net 11 and the columnar cylinder 12, and the whole rice is stuck in the mesh of the columnar net 11 and finally falls into the collector 2 under the drive of the columnar net 11.
[0045] The broken rice is finally discharged from the screen 1 through the discharge trough on the cylindrical barrel 12, and the whole rice is discharged from the screen 1 through the collector 2. At this point, the separation of broken rice and whole rice is completed.
[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
