[0024] Reference Figure 1 A rice storage and feeding device with impurity removal function is ingeniously designed and fully functional, aiming to provide an efficient, clean and quantitative raw material supply solution for rice processing equipment (especially rice washing machine 11).
[0025] The equipment includes a rice silo 4 for storing rice, an elevator 3 that works in conjunction with the rice silo 4, and a vacuum feeder 8 for feeding rice. The rice silo 4 is the core storage part of the equipment, used for storing large quantities of rice. Its design takes into account the needs of rice preservation, moisture prevention, and insect prevention, ensuring that the rice maintains its high quality during storage. The elevator 3 serves as a vertical transport tool for rice from the ground to the rice silo 4, used to realize the feeding operation of the rice silo 4. The vacuum feeder 8 is responsible for sucking up the rice from the rice silo 4 and conveying it to the external rice washing machine 11, used to realize the feeding operation of the external rice washing machine 11. The vacuum pump is the core component of the vacuum feeder 8, responsible for generating negative pressure to drive the material to flow in the pipeline.
[0026] Specifically:
[0027] The elevator 3 is vertically arranged. A feeding inlet is provided at the lower part of one side of the elevator 3 to receive rice. A destoner 2 is connected to the feeding inlet to remove heavy impurities such as stones and sand from the rice. An iron remover 1 is installed at the inlet of the destoner 2 to use magnetic force to adsorb metal impurities such as iron filings and nails from the rice. A discharge outlet is provided at the upper part of the other side of the elevator 3 and is connected to the top of the rice bin 4 to lift the rice to the rice bin 4 for storage.
[0028] Preferably, the outlet of the iron remover 1 is connected to the inlet of the destoner 2, the outlet of the destoner 2 is connected to the lifting feed inlet, and a hopper for easy rice input is also installed at the inlet of the iron remover 1.
[0029] A feeding port is provided at the bottom of the rice bin 4 to facilitate the output of rice to subsequent processing stages as needed. The feeding port is connected to a vacuum feeder 8 via a feeding pipe. The vacuum feeder 8 is responsible for sucking up the rice in the rice bin 4 and conveying it to the external rice washing machine 11. The vacuum feeder 8 is located above the external rice washing machine 11 to facilitate the rapid and accurate feeding of rice through the vacuum suction of the vacuum pump 10. A flow feeder scale 5 and a feeding valve 6 are also installed on the rice bin 4 at the feeding port. The flow feeder scale 5 is used to accurately measure the amount of rice fed. The feeding valve 6 is connected to the feeding pipe via a pipe adapter 7 to facilitate the control of the rice feeding flow rate and speed. The main function of the pipe adapter 7 is to realize the connection and conversion between different pipes, such as flange connection adapters, clamp adapters, etc.
[0030] A discharge port is provided at the bottom of the vacuum feeder 8. The discharge port is connected to the external rice washing machine 11 through a discharge pipe. A discharge valve 9 is also installed at the discharge port to open or close according to the needs of the rice washing machine 11, so as to control the amount and timing of rice discharge.
[0031] In actual use, the feeding valve 6 and the discharge valve 9 are both electric valves, which have many advantages such as high-precision control, high degree of automation, strong adaptability, safety and reliability, simple maintenance, and energy saving and environmental protection; the elevator 3 is a fully enclosed vertical elevator 3, which effectively prevents the rice from being contaminated during the lifting process; the destoner 2 is a gravity destoner 2, which adopts the principle of gravity destone removal and can effectively remove impurities with a large specific gravity such as stones and sand from the rice; the iron remover 1 is an electromagnetic iron remover 1, which uses the electromagnetic principle to generate a strong magnetic field, thereby adsorbing and removing iron impurities in the material. It is stable, reliable and has a strong iron removal capacity.

[0036] 2. The destoner 2 adopts the principle of gravity destone removal. Rice and impurities with a higher specific gravity, such as stones and sand, are separated inside the machine by vibration and airflow.

[0038] The destoned rice flows out from the outlet of the destoner 2 and enters the lifting inlet of the elevator 3;
[0039] 3. The fully enclosed vertical elevator starts, lifting the destoned rice from the feed inlet to the discharge outlet;
[0040] Rice flows from the discharge port into rice silo 4 for storage;
[0041] The design of Rice Warehouse 4 takes into account the needs of rice preservation, moisture prevention and insect prevention, ensuring that rice maintains its high quality during storage;
[0042] 4. When the rice washing machine 11 needs rice raw materials, the flow feeder 5 starts working to accurately measure the amount of rice fed.
[0043] According to the set feeding amount, the feeding valve 6 is opened, and rice flows out from the feeding port of the rice bin 4 and enters the vacuum feeder 8 through the feeding pipe;
[0044] When the vacuum feeder 8 is started, the vacuum pump 10 of the vacuum feeder 8 is used to draw rice from the feeding pipe and transport it to the discharge port.
[0045] 5. At the discharge port of the vacuum feeder 8, the discharge valve 9 opens or closes according to the needs of the rice washing machine 11 to control the amount and timing of rice discharge.
[0046] Rice flows into rice washing machine 11 through the feeding pipe for further cleaning.
