Description

TECHNICAL FIELD

[0002] Rice deep processing refers to a process of producing new rice products with high added value, high nutrition and stronger function or changed morphological characteristics by treating paddy or common white rice as raw materials through physical, chemical or biological techniques.

[0003] At present, common automatic cleaning equipment for rice deep processing is a conveying belt type rice washing machine which separates and removes dust, bran powder and impurities attached to the surface of rice grains by means of water flow impact and bubble burst, and the working process is as follows: continuous feeding, bubble and spray cleaning cooperation, conveying and discharging. However, in the continuous cleaning process, the conveying equipment is usually straight, and in order to ensure that the rice is fully cleaned, the conveying equipment is usually continuous and long, which occupies a large space. In addition, the floating rice grains cannot be completely submerged by the water flow when they are just fed, and the dust and impurities on the surface of the rice grains cannot be timely and effectively removed. Furthermore, in the area with a large amount of aeration, the dense bubbles surge upward, pushing the rice grains above to the surrounding, causing the accumulation of some rice layers around, the uneven thickness of local rice layers, and the insufficient cleaning.

[0004] Therefore, in order to improve the space utilization and the cleaning effect, the present application provides an automatic cleaning system for rice deep processing. SUMMARY

[0036] With reference to the drawings and embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the scope of the present application. Figures 1 to 3The front and rear side walls of the cleaning tank 1 are double-layer hollow detachable structures, the pollution discharge mechanism 5 comprises overflow grooves 51 symmetrically formed on the inner walls of the front and rear walls of the cleaning tank 1, the height of the overflow grooves 51 is lower than the right high position of the stepped section of the conveying assembly 21, and the height of the overflow grooves 51 is consistent with the top height of the discharge port 15; the double-layer hollow front and rear side walls of the cleaning tank 1 are provided with pollution discharge channels 52, the upper portions of the pollution discharge channels 52 are communicated with the overflow grooves 51, the lower portion of the left side wall of the cleaning tank 1 is provided with a pollution discharge port 53, the left portion of the pollution discharge channel 52 is communicated with the pollution discharge port 53, and the bottom portion of the pollution discharge channel 52 is inclined from the right upper portion to the left lower portion.

[0037] Referring to Figure 3 , Figure 5 and Figure 6 , the auxiliary mechanism 6 comprises a pollution discharge assembly 61 and a partition plate 63 arranged on the cleaning tank 1, the pollution discharge assembly 61 is provided with a brush roller 62, the pollution discharge assembly 61 comprises two water passing pipes 611 symmetrically arranged on the cleaning tank 1, the middle portions of the water passing pipes 611 are symmetrically communicated with two water flushing heads 612, and the cleaning tank 1 is fixedly connected with support rod groups 613 located between the two water passing pipes 611; the support rod groups 613 comprise two support rods symmetrically arranged, the middle portions of the support rods are rotatably connected with paddle members 614 corresponding to the water flushing heads 612, and the left and right corresponding paddle members 614 are fixedly connected with a pollution discharge roller 615; the bottom walls of the two support rods are symmetrically fixedly connected with support frames in the shape of inverted convex characters, the brush roller 62 is arranged above the stepped horizontal section of the conveying assembly 21, and the partition plate 63 is fixedly connected to the front and rear walls of the cleaning tank 1 and located between the separation zone 13 and the purification zone 14.

[0038] The cleaning tank 1 is provided with a circulating water inlet mechanism (existing mature technology, not described in detail, not shown in the figure), and the water level in the cleaning tank 1 is always kept flush with the top position of the discharge port 15. The rice is fed from the feeding port 11 and discharged from the discharge port 15. The rice is lifted and conveyed in a stepped manner from left to right in the cleaning tank 1 by the conveying mechanism 2 and sequentially passes through the flushing zone 12, the separation zone 13 and the purification zone 14. In the flushing zone 12, the rice enters the rice flushing stage. The corresponding spray mechanism 4 and the aeration pipe group 3 flush the light and floating rice grains into the water from the upper and lower directions and make the rice fully soaked in the deep water. In the separation zone 13, the rice enters the impurity separation stage. The corresponding aeration pipe group 3, pollution discharge mechanism 5 and auxiliary mechanism 6 cooperate with the bubble flotation impurity and the stepped lifting of the rice position to deeply clean the rice and light impurities and promote the timely discharge of impurities. In the purification zone 14, the rice enters the spray purification stage. The rice lifted out of the water surface is washed and purified by the corresponding spray mechanism 4. Through the rice flushing stage, the impurity separation stage and the spray purification stage, the rice is subjected to a stepped and efficient cleaning operation from deep to shallow water depth.

[0039] Rice is conveyed by the conveying assembly 21 in the cleaning tank 1 from left to right in a stepped manner, and the mesh belt section 211 is inclined when transitioning between the horizontal height at the lower part and the horizontal height at the higher part. Through the vertical superposition, a longer total cleaning path can be achieved in a smaller floor area, improving the space utilization.

[0040] The aeration pipe group 3 generates countless fine and uniform bubbles in the water. The bubbles pass through the bubble passing port 212 and continuously hit the surface of the rice immersed in the water during the floating process, and the impurities are stripped from the surface of the rice by the floating movement of the bubbles and float to the surface of the water body.

[0041] In the rinsing area 12, the rice enters the rinsing stage. The corresponding spray mechanism 4 and aeration pipe group 3 from the top and bottom directions flush the light and floating rice grains into the water and fully immerse the rice in the deep water. Specifically, after the rice is fed from the feeding port 11, most of the rice is immersed in the water and falls onto the conveying assembly 21 below. The conveying assembly 21 at this position is horizontal, and the aeration pipe group 3 performs primary bubble cleaning on the rice grains. At this time, a small part of the light and floating rice grains float on the water surface, and the water sprayed by the spray head 42 has a certain impact force, which can flush the small part of the light and floating rice grains into the water, so that the floating rice grains cannot be completely submerged by the water flow, and the dust and impurities on the surface of the rice grains cannot be effectively flushed away by bubble cleaning.

[0042] The water in the rinsing area 12 is relatively deep, and after being impacted by the water flow of the spray head 42, the rice grains are all immersed in the water. The rice has enough time and depth to be fully immersed. The water penetrates into the micro cracks on the surface of the rice grains and the junctions between the rice grains and the impurities, and the attached impurities become loose and easy to be stripped by bubble cleaning.

[0043] In the separation area 13, the impurities enter the separation stage. The corresponding aeration pipe group 3, sewage discharge mechanism 5 and auxiliary mechanism 6 cooperate with the bubble flotation of impurities and the stepped lifting of rice position to deeply clean the rice and light impurities and promote the timely discharge of impurities. Specifically, the conveying assembly 21 is conveyed in a stepped manner from left to right. As the conveying assembly 21 is lifted, the water depth where the rice is located gradually becomes shallower, and the rice gradually moves from the bottom of the turbid sewage to the upper layer of clear water. The inclination of the conveying assembly 21 cooperates with the bubbles of the aeration pipe group 3 to further clean the rice grains. The inclined surface helps to turn over the bottom rice layer, improves the problem of accumulation around and uneven thickness of the local rice layer formed by the bubble flushing, and ensures that the rice grains have the opportunity to be directly impacted by the bubbles and the spray water, improving the uniformity of cleaning and facilitating deep cleaning.

[0044] In the horizontal section of the conveying assembly 21, the brush roller 62 physically rubs and scatters part of the rice clusters, further removing part of the bran and defects on the surface of the rice.

[0045] The impurities are stripped from the surface of the rice grains and float to the surface of the water body. At this time, the water impact head 612 is tilted to spray water to impact the paddle member 614, and the paddle member 614 is rotated to drive the sewage rollers 615 to rotate. The rear sewage roller 615 rotates clockwise forward, and the front sewage roller 615 rotates counterclockwise backward. The front and rear sewage rollers 615 push the impurities to the overflow groove 51 on the corresponding front and rear side walls, accelerate the discharge of the light impurities, and discharge the light impurities from the cleaning tank 1 through the sewage channel 52 and the sewage outlet 53 in time, preventing the separated impurities from re-attaching to the surface of the clean rice grains and causing secondary pollution.

[0046] It should be noted that the water pipeline one 41 and the water pipeline two 611 are connected through a water pump (not shown in the figure) and a water storage device (not shown in the figure) outside the cleaning tank 1. The water sprayed by the spray head 42 is umbrella-shaped, and the water sprayed by the water impact head 612 is columnar. The brush roller 62 is made of food-grade, soft and elastic material, such as nylon and polypropylene, which gently contacts the surface of the rice layer. The device is suitable for cleaning operation of brown rice or white rice before being processed into rice flour and rice noodles, so the integrity of the rice grains is not high.

[0047] In the purification area 14, the rice grains lifted out of the water surface enter the spray purification stage. The corresponding spray mechanism 4 is used to wash and purify the rice grains, as follows: the conveying assembly 21 lifts the rice grains out of the water surface into the purification area 14. The partition plate 63 blocks the impurities on the water surface in the left separation area 13. The spray head 42 sprays the rice grains to wash and remove the residual wastewater and a small amount of impurities on the surface of the rice grains, further improving the cleaning and purification effect.

[0048] The application carries out deep-to-shallow step efficient cleaning operation on rice through rice flushing stage, impurity separation stage and spray purification stage, and the rice is lifted and conveyed in a step shape from left to right by the conveying assembly 21 and sequentially passes through the flushing area 12, the separation area 13 and the purification area 14, the land area is reduced in a certain cleaning path, and the space utilization is improved. In the flushing area 12, the rice flushing stage is entered, and the corresponding sewage mechanism 5 and the aeration pipe group 3 flush the light and floating rice grains into the underwater from the upper and lower two directions and make the rice fully soak in the deep water, the floating rice grains are completely submerged by the water flow, the rice has enough time and depth to be fully soaked, and the dust and impurities on the surface are effectively flushed away by the bubble cleaning; in the separation area 13, the impurity separation stage is entered, and the corresponding aeration pipe group 3, sewage mechanism 5 and auxiliary mechanism 6 cooperate with the step-shaped lifting of the rice position to gradually lift the turbid sewage far from the bottom to the upper layer of clean water, completely turn over the bottom rice layer, ensure that the rice grains have the opportunity to be directly impacted by the bubbles and spray water, improve the uniformity of cleaning, accelerate the discharge of light impurities, and prevent the separated impurities from reattaching to the clean rice surface to cause secondary pollution; in the purification area 14, the spray purification stage is entered, and the rice lifted away from the water surface is flushed and purified by the corresponding sewage mechanism 5, and the residual wastewater and a little impurities on the surface of the rice are removed, so that continuous and efficient cleaning operation is realized.
