Technical Field

[0001] The present application relates to the technical field of rice processing, and in particular to an impurity removal device for rice pretreatment. Background Art

[0002] Pretreatment is a crucial step in rice processing. After harvest, rice often contains various impurities, such as large particles, stones, and straw. Failure to remove these impurities can severely impact subsequent processing equipment and the quality of the finished product. Furthermore, rice moisture content is a key factor influencing processing quality and storage stability, making drying and kilning essential.

[0003] However, the rice cleaning equipment currently available on the market is relatively limited in its functionality, focusing on either removing impurities or drying the rice. This results in the rice needing to be transported and handled multiple times before processing, increasing production costs and reducing efficiency. Specifically, existing rice cleaning equipment typically performs a preliminary screening of impurities, while addressing moisture content in the rice requires separate drying equipment.

[0004] In view of the above problems, a kind of impurity removal equipment for rice pretreatment is now designed. Utility Model Content

DETAILED DESCRIPTION

[0026] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0027] The embodiment of the present application provides an impurity removal device for rice pretreatment, which can solve the problem that the existing rice impurity removal equipment in the related art has relatively single functions and affects the processing efficiency.

[0028] See also Figure 1-Figure 3A de-impurity device for rice pretreatment comprises: a base 1, a support spring 2 is provided on the base 1, a de-impurity box 3 is provided on the support spring 2, a chamber for removing rice de-impurities is provided inside the de-impurity box 3, a guide plate 4 for guiding rice is provided inside the de-impurity box 3, a filter screen 5 is provided at one end of the guide plate 4, a vibration motor 6 is provided at the bottom of the de-impurity box 3, a discharge port 7 for outflow of filtered rice is provided at the bottom of the de-impurity box 3, and a slag discharge port 8 for outflow of impurities is provided at the bottom of the de-impurity box 3;

[0029] The base 1 is also provided with an air supply component 9, which is used to dry the rice flowing on the guide plate 4;

[0030] The air supply assembly 9 includes a hot air supply part 91 arranged on the base 1, and a plurality of hoses 92 are provided on the hot air supply part 91. The other end of the hose 92 is connected to the impurity removal box 3 for sending the hot air flow of the hot air supply part 91 into the impurity removal box 3.

[0031] The rice is first fed into the chamber of the impurity removal box 3 and lands on the guide plate 4. The design of the guide plate 4 allows the rice to flow along a specific path, facilitating subsequent impurity removal and drying. As the rice flows, the vibration motor 6 starts to operate, generating vibrations that cause the impurity removal box 3 and the rice inside to vibrate. This vibration helps separate impurities such as stone particles and straw from the rice itself, allowing them to slide down the filter screen 5 to the slag discharge port 8, thereby removing the impurities.

[0032] At the same time, the air supply assembly 9 also begins operating. The hot air supply unit 91 generates a hot air flow and delivers it to the interior of the impurity removal chamber 3 via a hose 92. The hot air flows through the impurity removal chamber 3, coming into contact with the rice on the guide plate 4, removing moisture from the rice and drying it. The dried rice continues to flow along the guide plate 4, ultimately exiting through the discharge port 7 for subsequent processing.

[0033] The vibration generated by the vibration motor 6 and the screening effect of the filter 5 can effectively remove large impurities, stone particles, straw, etc. from the rice, improving the purity of the rice. The hot air flow generated by the air supply component 9 can evenly blow over the rice on the guide plate 4, quickly removing moisture from the rice and achieving rapid drying of the rice. This drying method is not only highly efficient but also prevents damage to the rice during the drying process. In this way, the impurity removal and drying functions can be integrated, achieving integrated rice processing. This not only simplifies the rice processing process and reduces production costs, but also improves work efficiency and product quality.

[0034] The impurity removal box 3 in this embodiment includes a box body and a box cover connected by bolts. A feed hopper is provided above the box cover. The interior of the box body is hollow, and the top thereof is open.

[0035] Specifically, in this embodiment, the base 1 has a receiving groove 11 for receiving the debris removal box 3 , and a groove 12 is formed on the receiving groove 11 , and the support spring 2 is arranged inside the groove 12 .

[0036] The receiving groove 11 provided on the base 1 provides a stable support platform for the debris removal box 3. The shape and size of the receiving groove 11 match the debris removal box 3, ensuring that the debris removal box 3 can be stably placed in the receiving groove 11 without shaking or displacement.

[0037] Groove 12 provides a mounting location for support spring 2. One end of support spring 2 is fixed to the bottom of groove 12, and the other end is connected to the dust removal box 3. When the vibration motor 6 is turned on, the dust removal box 3 is subjected to the vibration force from the vibration motor. Support spring 2 acts as a buffer and shock absorber, ensuring that the dust removal box 3 remains stable during vibration, preventing damage to the equipment or scattering of rice due to severe vibration.

[0038] It should be noted that there are four support springs 2 , and the four support springs 2 are distributed in two grooves 12 in a rectangular shape;

[0039] The support spring 2 includes a mounting seat 21 and a compression spring 22 connected to each other. A fixing block 23 is provided on the top of the compression spring 22. The fixing block 23 is connected to the debris removal box 3.

[0040] Mounting base 21 provides stable support for compression spring 22. Compression spring 22 provides elasticity, allowing the debris removal box 3 to remain stable during vibration and adapt to varying vibration intensities. Fixing block 23 is connected to the top of compression spring 22 and to the sidewall of the debris removal box 3, ensuring that support spring 2 can effectively support the debris removal box 3.

[0041] The rectangular distribution of the four support springs 2 also ensures the stability of the debris removal box 3 during vibration. Even when one support spring 2 is subjected to greater pressure, the other three support springs 2 can provide sufficient supporting force to prevent the debris removal box 3 from tilting or shifting.

[0042] In one embodiment, an opening is provided between the end of the filter screen 5 away from the guide plate 4 and the impurity removal box 3, the slag discharge port 8 is located below the opening, and a baffle 51 is provided at the bottom of the end of the filter screen 5 away from the guide plate 4, the baffle 51 being located between the filter screen 5 and the slag discharge port;

[0043] The discharge port 7 is located below the filter 5 , and a second baffle 41 is obliquely provided between the bottom of the guide plate 4 and the bottom of the impurity removal box 3 , and one end of the second baffle 41 away from the guide plate 4 faces the discharge port 7 .

[0044] An opening is provided between the end of the filter screen 5 away from the guide plate 4 and the impurity removal box 3, which allows impurities to slide off the filter screen 5 during vibration. The slag discharge port 8 is located below this opening, ensuring that impurities can be discharged from the impurity removal box 3 smoothly.

[0045] To prevent impurities from remixing with the filtered rice during the sliding process and causing secondary contamination, a baffle 51 is installed at the bottom of the filter screen 5 away from the guide plate 4. The baffle 51 is located between the filter screen 5 and the slag discharge port 8. It acts as a guide, allowing impurities to slide smoothly along the baffle 51 to the slag discharge port 8 without accumulating at the bottom of the filter screen 5, causing secondary mixing with the rice or clogging the slag discharge port 8.

[0046] Discharge port 7 is located below filter screen 5, ensuring that clean rice, filtered through filter screen 5, falls directly into discharge port 7 without mixing with impurities. Furthermore, a second baffle 41 is positioned at an angle between the bottom of guide plate 4 and the bottom of impurity removal box 3. The end of baffle 41, facing away from guide plate 4, faces discharge port 7, guiding the flow of rice, allowing it to slide smoothly along baffle 41 to discharge port 7.

[0047] Furthermore, the filter screen 5 and the material guide plate 4 are inclined downward at one end close to the opening.

[0048] The filter screen 5 and the guide plate 4 are designed to be tilted downward at one end near the opening, which helps the rice and impurities to flow more smoothly during the vibration process, avoiding the problems of blockage and accumulation.

[0049] The inclined guide plate 4 ensures that the rice can flow continuously and stably, avoiding the reduction of the impurity removal efficiency due to accumulation or blockage.

[0050] In one embodiment, the hot air supply unit 91 includes a box body 911 , a plurality of heating wires 912 are arranged inside the box body 911 , a fan 913 is arranged on the box body 911 , an air inlet of the fan 913 is connected to the outside, and a departure port of the fan 913 is connected to the box body 911 .

[0051] Several heating wires 912 are installed inside the housing 911. These heating wires 912 are the primary heat generators. They generate heat through the action of an electric current, which in turn heats the air inside the housing 911. The air inlet of the fan 913 is connected to the outside world, allowing the fan 913 to draw in outside air into the housing 911. After being heated by the heating wires 912, this airflow is formed.

[0052] When providing hot air flow for drying the rice, the heating wire 912 starts working, generating heat and heating the air inside the box 911. At the same time, the fan 913 also starts running, sucking air from the outside and blowing it into the box 911. After the air is heated by the heating wire 912 inside the box 911, the temperature rises, forming a hot air flow. This hot air flow is sent to the inside of the impurity removal box 3 through the hose 92, and the rice is dried. When the hot air flow flows inside the impurity removal box 3, it will fully contact the rice, remove the moisture in the rice, and achieve rapid drying of the rice.

[0053] In this embodiment, one end of the receiving tank 11 is open, and one end of the impurity removal box 3 extends to the outside of the receiving tank 11 .

[0054] One end of the impurity removal box 3 is designed to extend to the outside of the receiving tank 11. This design allows the impurity removal box 3 to remain stable during the vibration process, while facilitating the input of rice and the discharge of impurities.
