Description

Technical Field

[0001] This utility model relates to a purification and screening device, specifically an automatic purification and screening device for rice processing, belonging to the field of rice processing technology. Background Technology

[0002] Rice is a finished product made from paddy through processes such as cleaning, hulling, milling, and packaging. Before processing, paddy often has a lot of impurities and dust on its surface, so screening devices are needed to screen it during the rice processing.

[0003] Chinese Patent Publication CN221335244U discloses a rice screening device for rice processing. When the motor is started, the motor drives the first rotating shaft, the driving wheel and the rotating disk to rotate synchronously. The driving wheel drives two driven wheels, the second rotating shaft and the fan blade to rotate synchronously through the conveyor belt. When the rotating disk drives the fixed block to rotate, the vibrating rod vibrates up and down in the fixed sleeve, thereby vibrating the two screen boxes respectively.

[0004] The aforementioned patented technology can automatically remove dust and bran from rice a second time, avoiding the impact on the device's impurity removal effect due to its ability to remove impurities only once. However, in actual use, this device lacks the ability to collect dust; dust on the surface of the rice is blown off by the fan blades and floats inside the box. If the dust is not cleaned in time, it can easily cause secondary adhesion to the rice, reducing the effectiveness of the automatic impurity removal and screening device for rice processing. Therefore, an automatic impurity removal and screening device for rice processing is proposed here. Utility Model Content

[0027] Please see Figures 1-4 This utility model provides an automatic impurity removal and screening device for rice processing, including a box 1, and a collection mechanism 2 is provided on the left side of the box 1;

[0028] The collection mechanism 2 includes an auxiliary box 201. The right side of the auxiliary box 201 is fixedly connected to the left side of the box body 1. An air suction pipe 202 is fixedly connected to the upper surface of the auxiliary box 201. The right end of the air suction pipe 202 is fixedly connected to the left side of the box body 1. A negative pressure pump 203 is fixedly connected to the right side of the auxiliary box 201. A support block 5 is fixedly connected to the outer surface of the negative pressure pump 203. The right side of the support block 5 is fixedly connected to the left side of the auxiliary box 201. The negative pressure pump 203 draws air from the auxiliary box 201, and the support block 5 can support the negative pressure pump 203, providing a good stress point for the negative pressure pump 203.

[0029] Please refer to this carefully. Figure 1 and Figure 2The auxiliary box 201 has a filter plate 204 snapped into its interior. Two sets of support legs 6 are fixedly connected to the bottom of the box 1. Each set of support legs 6 has a stabilizing block 7 fixedly connected to its outer surface. The support legs 6 can increase the working height of the auxiliary box 201, increasing the convenience when using the device. The stabilizing block 7 can increase the contact area between the support legs 6 and the ground, improving the stability when supporting.

[0030] Please refer to this carefully. Figure 3 and Figure 4 The auxiliary box 201 has a collection box 205 slidably connected inside. The inner wall of the box 1 is fixedly connected to a vertical air duct 206. The outlet of the negative pressure pump 203 is fixedly connected to a conveying air duct 207. The right end of the conveying air duct 207 is fixedly connected to the left side of the vertical air duct 206. The front of the collection box 205 is fixedly connected to an auxiliary handle 8. The outer surface of the auxiliary handle 8 is fixedly connected to an anti-slip sleeve 9. The auxiliary handle 8 can provide an effective force-bearing position for the collection box 205, increasing the convenience when pulling the collection box 205. The anti-slip sleeve 9 can improve the firmness when gripping the auxiliary handle 8, increasing the convenience of the device.

[0031] Please refer to this carefully. Figure 3 The auxiliary box 201 is equipped with an anti-clogging mechanism 3, which includes a scraper 301. The scraper 301 is slidably connected to the inside of the auxiliary box 201. An electric telescopic rod 302 is fixedly connected to the inner wall of the auxiliary box 201. The telescopic end of the electric telescopic rod 302 is fixedly connected to the upper surface of the scraper 301. The scraper 301 is moved by the thrust generated by the electric telescopic rod 302. During the movement, the scraper 301 can continuously rub the filter plate 204, thereby pushing the dust adhering to the surface of the filter plate 204 into the collection box 205 for storage.

[0032] Please refer to this carefully. Figure 1 and Figure 2 The box 1 is equipped with a screening mechanism 4, which includes a feed pipe 401. The outer surface of the feed pipe 401 is fixedly connected to the inner wall of the box 1. The box 1 is equipped with two screening plates 402. The inner wall of the box 1 is fixedly connected to a guide plate 403. The right side of the box 1 has two discharge ports 404. The right side of the box 1 is slidably connected to a collection box 405. The inside of the box 1 is slidably connected to a waste box 406. Rice is added into the box 1 through the feed pipe 401. The rice is screened by the two screening plates 402 and the guide plate 403. The screened rice is guided to the collection box 405 through the discharge port 404. Impurities are stored in the waste box 406.

[0033] When using this utility model: First, connect the negative pressure pump 203 and the electric telescopic rod 302 to the power supply. When it is necessary to screen the rice, pour the rice into the box 1 through the feed pipe 401. At this time, the rice will be screened twice through the screening plate 402 and the guide plate 403. After screening, the rice will fall into the collection box 405 through the discharge port 404. At the same time, the rice with weight impurities will fall into the waste box 406.

[0034] When dust collection is required, the negative pressure pump 203 is activated to extract air from the auxiliary box 201 and guide it through the conveying duct 207 to the vertical duct 206. The air is then blown into the box 1 through the vertical duct 206, causing the dust inside the box 1 to float in the air. At the same time, the auxiliary box 201 is under negative pressure. The suction pipe 202 continuously draws in the dust-laden air inside the box 1 and guides the air into the auxiliary box 201. The filter plate 204 then filters the dust from the air, leaving it on the surface of the filter plate 204. The electric telescopic rod 302 pushes the scraper 301 to move. During the movement, the scraper 301 pushes the dust adhering to the surface of the filter plate 204 downward, causing the dust to fall into the collection box 205. This completes the dust collection, preventing dust from accumulating inside the box 1 and causing secondary adhesion to the rice, effectively increasing the efficiency of the automatic impurity removal and screening device for rice processing.
