Description

[0001] The application belongs to the technical field of rice processing, and specifically relates to a dust centralized settling device and method for rice finishing. BACKGROUND

[0002] The dust centralized settling device is a device specially designed for collecting and treating dust in the rice processing process. A large amount of dust is generated in the rice finishing process, such as cleaning, hulling and milling, which not only pollutes the environment and affects the quality of rice, but also threatens the health of workers.

[0003] The existing settling device for rice finishing mostly adopts dry dust setting and spraying dust setting. In the spraying centralized settling process, in order to reduce production cost and maintenance difficulty, the traditional pressure type nozzle is generally used for spraying dust setting, which mainly consists of a spray hole and a simple water flow channel, so that water is sprayed from the spray hole in a fixed direction under the action of pressure. Since the area space in the dust setting box is large, if the spraying device can only spray in one direction, the water mist can only cover the area in this direction and its vicinity, and the area far from the spraying direction is difficult to be affected by the water mist, so that the dust in the corner area cannot be contacted with the water mist, thereby reducing the dust capture rate and causing the dust to be unable to effectively settle, thus reducing the overall settling efficiency of the device. Therefore, the dust centralized settling device and method for rice finishing are proposed to solve the problems in the background. SUMMARY

[0039] As shown in Figure 1 , Figures 3 to 5 , the water conveying assembly 2 comprises a water storage tank 21, the top of the water storage tank 21 is fixedly connected with a water pump 22, the output end of the water pump 22 is fixedly connected with a water conveying pipe 23 in communication with the water conveying pipe 5, the top end of the water conveying pipe 23 is movably clamped in the inside of the water conveying pipe 5, the output shaft end of the first motor 3 is fixedly connected with the rotating drum 41, the arc groove 42 is corrugated, the end of the round rod 43 away from the gear plate 44 is fixedly connected with a protruding block, the protruding block is movably connected in the inside of the arc groove 42, the gear plate 44 is meshed and connected with the gear 45, the inside of the nozzle 6 is provided with an atomizing piece, and the top end of the nozzle 6 is in communication with the water conveying pipe 5.

[0040] By means of the above scheme, the atomizing piece is arranged in the inside of the nozzle 6, which can break the water into small droplets, and the small droplets have a larger specific surface area than ordinary water droplets in the process of spraying and dust falling, so that the contact opportunity of the droplets and the dust particles is greatly increased, and when the droplets and the dust particles contact, the dust particles can be more effectively adsorbed, so that the dust particles are aggregated and weighted, and thus the dust particles can be more quickly settled under the action of gravity.

[0041] As shown in Figures 2 to 3 , Figures 6 to 8As shown, the output shaft end of the second motor 7 is fixedly connected with the rotating rod 81, the guide groove 82 is composed of a horizontal groove and an inclined groove with an arc of 360 degrees, the two ends of the horizontal groove are respectively connected with the two ends of the inclined groove, the middle part of the sliding block 83 is fixedly connected with the connecting column 84, the connecting column 84 is movably connected in the inside of the guide groove 82, the side of the sliding block 83 is fixedly connected with two elastic sheets 85, the sliding block 83 is elastically connected with the dust falling chamber 1 through the elastic sheets 85, the opposite ends of the two limiting blocks 93 are movably arranged in the inside of the sliding block 83, the top of the limiting block 93 is fixedly connected with the spring 86, the limiting block 93 is elastically connected with the sliding block 83 through the spring 86, the end, away from the spring 86, of the limiting block 93 is provided with a round block, the two sides of the inner wall of the dust falling chamber 1 are both provided with the sliding groove 94, the sliding groove 94 is trapezoidal, the round block on the limiting block 93 is movably arranged in the inside of the sliding groove 94, the bottom end of the scraper 91 is beveled, the two ends of the top of the scraper 91 are both fixedly connected with the supporting rods 92, the top ends of the supporting rods 92 are fixedly connected with the limiting blocks 93, the inner wall of the dust falling chamber 1 is respectively provided with the square groove matched with the sliding block 83 and the limiting block 93.

[0042] By the design of the elastic sheets 85 and the springs 86, when the connecting column 84 drives the sliding block 83 to move a distance, the round block at one end of the limiting block 93 moves upward along the track of the sliding groove 94, the limiting block 93 moves upward while pressing the spring 86, and the supporting rods 92 drive the scraper 91 to move upward, when the connecting column 84 completely slides into the horizontal groove of the guide groove 82, the sliding block 83 quickly resets along the track of the horizontal groove of the guide groove 82 under the action of the elastic force of the elastic sheets 85, the sliding block 83 resets while driving the two limiting blocks 93 to slide along the top end of the sliding groove 94, so that the scraper 91 reversely moves while always leaving a gap with the bottom of the inner cavity of the dust falling chamber 1, thereby preventing the scraper 91 from bringing back residual powder when resetting, and ensuring the normal operation of the device.

[0045] During the dust falling process, the second motor 7 is started, so that the second motor 7 operates once every certain period of time, and each operation drives the rotating rod 81 to rotate one revolution, and the rotating rod 81 drives the connecting column 84 to slide along the track of the guide groove 82 at the same time, and then the guide groove 82 drives the two limiting blocks 93 to move towards the second motor 7, and the limiting blocks 93 drive the scraper 91 to move in the same direction through the supporting rod 92 at the same time, so as to drive the scraper 91 to scrape off the wet dust at the bottom of the dust falling chamber 1, preventing too much dust from remaining at the bottom and causing blockage at the bottom of the dust falling chamber 1.
