[0032] The utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0033] The embodiment relates to a rice washing device for rice, which is used for washing rice grains so as to facilitate subsequent production of finished rice. In the overall structure, a barrel body 1 is included. The barrel body 1 is provided with a partition net 2, which divides the barrel body 1 into two parts. A vertical rotating roller 3 is arranged in the upper part of the barrel body 1. A plurality of stirring rods 301 are arranged on the rotating roller 3. A first motor 101 connected with the rotating roller 3 and a feeding hopper 102 are arranged on the top cover of the barrel body 1. The lower part of the barrel body 1 is connected with a water inlet pipe 103. The partition net 2 is connected with the inlet of a discharge valve 4, so that the discharge valve 4 connects the upper part of the barrel body 1 with the outside of the barrel body 1.

[0034] As described above, through the arrangement of the barrel body 1 and the stirring rods 301, the cleaning water can enter the upper part of the barrel body 1 through the partition net 2, and the cleaning water and the rice grains entering from the top of the barrel body 1 can generate convection. The stirring rods 301 can stir the rice grains mixed with the cleaning water, so as to clean the rice grains. The partition net 2 is connected with the inlet of the discharge valve 4, so that the cleaned rice grains can be directly discharged to the outside of the barrel body 1 through the discharge valve 4, so as to obtain the rice grains. Compared with the manual rice washing and rice cleaning method in the prior art, the labor intensity is reduced, and the rice washing effect and efficiency are improved.

[0035] Based on the above overall introduction, specifically, the barrel 1 of the embodiment is arranged on a rack, and the lower part of the barrel 1 is connected to the water inlet pipe 103. The cleaning water flows from right to up through the separation net 2, which not only can generate convection with the rice to improve the cleaning effect, but also can prevent the rice from blocking the holes on the separation net 2 to some extent when the cleaning water passes through the separation net 2, thereby avoiding the separation net 2 from being blocked, so as to improve the maintenance period of the rice washing device of the embodiment. In the specific implementation, the separation net 2 is a stainless steel net.

[0036] In addition, when the rice is discharged, the cleaning water in the barrel 1 will flow out with the rice, so the discharge valve 4 of the embodiment can preferably adopt the conventional discharge valve 4 for granular materials which is well known to those skilled in the art. The discharge valve 4 usually has an impeller which can be driven to rotate. In the embodiment, when the impeller in the discharge valve 4 rotates, the impeller can carry a certain amount of rice and cleaning water and discharge them out of the barrel 1. It can be understood that the use of the above-mentioned discharge valve 4 can prevent a large amount of cleaning water from flowing out of the barrel 1 during discharge, thereby achieving the effect of saving water.

[0037] In order to facilitate the discharge of the rice in the barrel 1 through the discharge valve 4, the separation net 2 of the embodiment is in the shape of a funnel, and the bottom end of the separation net 2 is connected to the inlet of the discharge valve 4. By arranging the funnel-shaped separation net 2, the rice can be collected at the bottom end of the separation net 2, so as to facilitate the concentration of the rice at the discharge valve 4, thereby facilitating the discharge of the rice.

[0038] In addition, since the discharge valve 4 is arranged at the bottom of the barrel 1, in order to facilitate the reception of the discharged rice, the discharge valve 4 of the embodiment is connected to the outlet of the conveying device 5 outside the barrel 1. The conveying device 5 includes a housing 501 connected to the discharge valve 4, a rotating shaft 502 rotatably arranged in the housing 501, a spiral blade 503 arranged on the rotating shaft 502, and a second motor 504 for driving the rotating shaft 502. One end of the housing 501 is provided with the second motor 504, and the other end of the housing 501 has a discharge port. Through the arrangement of the conveying device 5, the rice can be transported horizontally to one side of the barrel 1, so as to facilitate the placement of a container on one side of the rice washing device for rice of the embodiment, thereby receiving the rice.

[0039] On this basis, the unloading valve 4 of the embodiment can simultaneously discharge a certain amount of rice and cleaning water, so that the conveying device 5 simultaneously conveys rice and cleaning water. In order to reduce the water content of the rice, the bottom of the housing 501 of the embodiment is provided with a drainage window, and a filter screen 505 is arranged at the drainage window. Through the arrangement of the filter screen 505, when the spiral blade 503 conveys the rice and passes through the drainage window, the cleaning water in the conveying device 5 can flow out through the drainage window, and the rice is blocked by the filter screen 505 and continues to be pushed by the spiral blade 503 to the discharge port, so that the filter screen 505 in the conveying device 5 plays a role of filtering water, thereby reducing the water content of the rice and facilitating the subsequent use or storage of the rice.

[0040] In the embodiment, in order to prevent the rice from adhering to the separation net 2 and being unable to move to the unloading valve 4, the rotating roller 3 of the embodiment is provided with a scraper 303, the scraper 303 is connected to the rotating roller 3 through a connecting arm 304, and the scraper 303 is attached to the separation net 2. Through the arrangement of the scraper 303, the rotation of the rotating roller 3 can drive the scraper 303 to peel the rice on the separation net 2, so as to prevent the rice from adhering to the separation net 2. At the same time, the scraper 303 peeling the rice on the separation net 2 can also prevent the holes of the separation net 2 from being blocked by the rice to a certain extent.

[0041] In order to further improve the stirring effect of the stirring rod on the cleaning water and the rice in the barrel 1, so that the rice is fully contacted with the cleaning water to improve the rice washing effect, the stirring rod 301 of the embodiment is formed with a plurality of branches 302, and each branch 302 extends along the length direction of the rotating roller 3 and is arranged at intervals in the length direction of the stirring rod 301. The stirring rod 301 is provided with a plurality of branches 302, and the branches 302 extend along the length direction of the rotating roller 3, and have a larger contact area with the water body on the upper part of the barrel 1, so as to improve the stirring effect on the cleaning water in the barrel 1. The cleaning water in the barrel 1 can produce sufficient convection, so as to ensure the contact effect of the cleaning water and the rice, thereby improving the rice washing effect.

[0042] As a specific implementation form, in the process of washing rice, the dust and part of the rice bran, starch and other impurities on the surface of the rice grains remain in the cleaning water, in order to remove the impurities in the cleaning water, an annular water collecting groove 6 is formed on the outer periphery of the upper part of the barrel 1, and an opening 104 is arranged on the barrel wall of the barrel 1 corresponding to the position of the water collecting groove 6. The water in the barrel 1 can overflow through the opening 104 into the water collecting groove 6 and be discharged through the drain pipe 601 communicating with the water collecting groove 6. Specifically, the cleaning water in the barrel 1 flows from bottom to top, which can drive the impurities in the water to move to the top of the barrel 1, and at the same time, the cleaning water in the barrel 1 can overflow through the opening 104 into the water collecting groove 6. The cleaning water flowing into the water collecting groove 6 can carry the impurities, so as to transport the impurities in the barrel 1 to the water collecting groove 6 and finally discharge through the drain pipe 601. Therefore, by arranging the water collecting groove 6 and the opening 104 corresponding to the water collecting groove 6, the cleaning water in the barrel 1 can overflow through the opening 104 into the water collecting groove 6, so as to discharge the impurities in the cleaning water out of the barrel 1, realizing the effect of removing the impurities in the cleaning water and avoiding the decrease of the rice washing effect caused by too much impurities in the cleaning water.

[0043] Further, the lower part of the barrel 1 of the embodiment is provided with an annular aeration pipe 7 surrounding the inlet of the discharge valve 4 and connected with the gas source outside the barrel 1 through a gas conveying pipe 701. By arranging the aeration pipe 7, the aeration pipe 7 can disperse the gas in the barrel 1 and form a large number of small bubbles. When these bubbles rise in the cleaning water in the barrel 1, they can drive the impurities in the water to float up together, and at the same time, these bubbles can combine with the impurities to form bubble-particle flocs, further promoting the floating of the impurities, so as to discharge the impurities through the water collecting groove 6 and improve the cleaning effect of the impurities.

[0044] In summary, the rice washing device for rice of the embodiment can realize the following effects. By arranging the barrel 1 and the stirring rod 301, the cleaning water can pass through the partition net 2 to enter the upper part of the barrel 1, produce convection with the rice grains entering from the top of the barrel 1, and the stirring rod 301 can stir the mixed cleaning water and rice grains to clean the rice grains. The partition net 2 communicates with the discharge valve 4, so that the cleaned rice grains can be directly discharged out of the barrel 1 through the discharge valve 4, so as to obtain the rice grains. Compared with the manual rice washing and rinsing method in the prior art, the labor intensity is reduced, and the rice washing effect and efficiency are improved, which has good practicability.

[0045] The above merely describes the preferred embodiments of the present application and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
