Abstract
Description
Technical Field
[0001] This utility model relates to the field of rice processing technology, and in particular to a rice processing chaff and dust settling device. Background Technology
[0002] A rice processing bran and dust collection device, application number CN202120641660.3, includes a collection box with a discharge port. A fixing plate is fixed to one side of the collection box, and a motor is fixed to the fixing plate. A first connecting rod is provided at the output end of the motor. A first rotating rod is fixed to the first connecting rod. A second connecting rod is rotatably provided on the first rotating rod. A second rotating rod is rotatably provided on the second connecting rod. A connecting block is rotatably sleeved on the second rotating rod. The device includes a movable first filter screen. Fine bran and dust particles in the water adhere to the first filter screen through the movable first filter screen. The bran and dust particles on the first filter screen are collected by clamping and fixing the fixed frame. The device also includes a water pump, which can pump out the water in the collection box, thereby removing the collection box from the collection box and treating large bran and dust particles.
[0003] While the aforementioned technology can effectively filter and collect both large and small rice bran dust particles, it relies on water for filtration. This results in a significant amount of moisture remaining in the filtered rice bran dust, necessitating an additional drying step in subsequent production processes to remove this moisture. This increases workload and time costs, reducing the overall practicality and economic viability of the technology. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a rice processing chaff and dust settling device.

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0024] like Figures 1-4 As shown in the figure, this utility model embodiment proposes a rice processing bran dust collection device, comprising:
[0025] Box 1 has a feed hopper 18 extending through its top for pouring rice bran dust into it; a support 19 is fixedly installed at the bottom of box 1 for supporting it; a slag discharge port 11 extends through its bottom for discharging the smallest amount of rice bran dust or impurities; and multiple screening components are installed inside box 1.
[0026] The screening assembly includes a screening plate 2, a shaft 3, a screen 7, and a guide plate 8. The shaft 3 passes through one end of the screening plate 2 and is rotatably connected. One end of the shaft 3 is fixedly set on the inner wall of the housing 1. A torsion spring is provided at the rotating part of the shaft 3 and the screening plate 2, so that when the screening plate 2 rotates, the torsion spring can drive the screening plate 2 to reverse and reset.
[0027] A discharge port 4 is provided through the screening plate 2. A limiting groove 5 is provided on the discharge port 4. An installation frame 6 is provided inside the limiting groove 5. The limiting groove 5 is used to limit the installation frame 6. The screen 7 is fixedly installed inside the installation frame 6.
[0028] A magnetic block is fixedly installed in the limiting groove 5. The magnetic block is set in conjunction with the mounting frame 6. The mounting frame 6 is made of magnetic metal, so that the magnetic block can attract and fix the mounting frame 6, thereby fixing the screen 7. Push the mounting frame 6 upward out of the limiting groove 5 to separate it from the magnetic block, and the screen 7 can be removed for cleaning or replacement.
[0029] Both sides of the screening plate 2 are fixedly equipped with baffles 9, and the guide plate 8 is fixedly installed at the bottom of the screening plate 2. Both the screening plate 2 and the guide plate 8 are inclined, and the inclination directions of the screening plate 2 and the guide plate 8 are opposite. Multiple discharge plates 10 are installed through one side of the box body 1. The multiple discharge plates 10 are respectively installed below the lower end of the multiple screening plates 2, so that the screening plate 2 can guide the rice and dust to the discharge plates 10 and discharge them out of the box body 1.
[0030] The shaking assembly is used to drive the screen 7 to shake. The shaking assembly includes a motor 12, a turntable 13, a connecting rod 15, and a lifting plate 16. The motor 12 is fixedly installed on the outside of the housing 1, and the output end of the motor 12 is movably installed through the housing 1. The turntable 13 is fixedly installed on the output end of the motor 12, so that the motor 12 can drive the turntable 13 to rotate. A round rod 14 is fixedly installed on the turntable 13. One end of the round rod 14 is rotatably connected through the connecting rod 15, and the other end of the connecting rod 15 is hinged to the lifting plate 16, so that when the turntable 13 rotates, the round rod 14 and the connecting rod 15 can drive the lifting plate 16 to move up and down reciprocally. Multiple push plates 17 are fixedly installed on the inner side of the lifting plate 16. The multiple push plates 17 are respectively installed below the upper end of multiple screening plates 2, so that the lifting plate 16 and the torsion spring can drive the multiple screening plates 2 to rotate up and down reciprocally through the multiple push plates 17, thereby driving the chaff and dust on the screen 7 to shake, improving screening efficiency.
[0031] A fixing block 20 is fixedly installed on the outer side of the lifting plate 16, and a guide rod 21 is fixedly installed on the inner wall of the housing 1. The guide rod 21 slides through the fixing block 20 and guides the lifting plate 16.
[0032] The detailed working process of this utility model is as follows:
[0033] 1. In use, rice husks are poured into the box 1 through the feed hopper 18 and fall onto the uppermost screening plate 2. The screen 7 on the screening plate 2 can screen the rice husks. Rice husks smaller than the mesh size of the screen 7 will fall onto the screening plate 2 below for screening again. Rice husks larger than the mesh size of the screen 7 will slide down and be discharged through the discharge plate 10 below. This process is repeated to achieve the effect of multi-stage screening.
[0034] 2. At the same time, the motor 12 drives the round rod 14 to rotate through the turntable 13. The round rod 14 drives the lifting plate 16 to move up and down quickly and reciprocally through the connecting rod 15. The lifting plate 16 works in conjunction with the torsion spring (when the lifting plate 16 moves upward, it drives the screening plate 2 to rotate upward through the push plate 17. When the lifting plate 16 moves downward, the torsion spring drives the screening plate 2 to rotate in the opposite direction to reset). Multiple push plates 17 drive multiple screening plates 2 to rotate quickly and reciprocally, thereby causing the chaff and dust on multiple screens 7 to shake, improving the screening efficiency and avoiding clogging of the screens 7.
[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it.
