The third electric telescopic column 34 can adjust the distance between the scraper 33 and the connecting plate 31, and avoid the reduction of cleaning capacity after the scraper 33 is worn, so that the position of the scraper 33 can be freely adjusted, and the replacement frequency of the scraper 33 is reduced.
As a technical optimization scheme of the invention, a sliding plate 36 which is obliquely arranged below a second filter screen plate 40 is arranged in the frame box 1, one end of the bottom of the frame box 1 is provided with a discharge port 37, one end of the second filter screen plate 40 is connected with a barrier plate 39 on the upper part of the frame box 1, a storage tank is arranged between the barrier plate 39 and the second filter screen plate 40, and one end of the storage tank is connected with a slag discharge pipe 38.
When the rice flour screening machine is used, rice flour to be screened and decontaminated is placed into the loading box 16 from the feed hopper 17 for screening. During the screening, motor 25 drives second dwang 28 and rotates, and then drives outside a plurality of magnetism otter board 27 and rotates, and second dwang 28 and a plurality of magnetism otter board 27 mix the stirring to the rice flour that loads the inside of case 16 for the rice flour can obtain abundant mixture in inside. During the stirring process, iron particle impurities doped in the rice flour are adsorbed outside the magnetic screen plate 27. During the rice flour mixing and stirring process, the fan 14 is started to operate, the fan 14 pumps the stirred rice flour into the collecting pipe 13 through the suction pipe 15, and then the rice flour is conveyed into the middle frame 5 from the collecting pipe 13. During the extraction and adsorption process, the particles larger than the meshes of the magnetic screen plate 27 are filtered and fall into the loading box 16 without entering the interior of the extraction pipe 15. The particles made of other materials have a heavy weight and are hard to be sucked into the suction pipe 15 by wind, so that the particles made of other materials can remain in the loading box 16 and cannot enter the middle frame 5. And (4) primary filtering, namely screening iron particles and particles made of other materials doped in the rice flour and particles larger than the meshes of the magnetic screen plate 27. The screening efficiency is high, and the screening cost is low.
If the interior of the loading box 16 or the magnetic screen plate 27 needs to be cleaned, the sealing plate 24 is detached from one end of the loading box 16, and the second rotating rod 28 and the magnetic screen plate 27 are taken out, so that the cleaning of the interior of the magnetic screen plate 27 and the loading box 16 is facilitated. The cleaning is convenient and fast, and the cleaning can be more sufficient.
The rice flour after primary filtration enters the inner part of the middle frame 5 from the collecting pipe 13 through the connecting hose 12. When the ground rice disperses in the inside of middle part frame 5, first rotation pole 9 drives middle part frame 5 and control the circulation and rock between two risers for middle part frame 5 can play the effect of rocking, is favorable to the dispersion of inside ground rice. And a plurality of rotating shafts 8 rotate to drive a plurality of outer leaf plates 10 to incite the rice flour inside. The rice flour which is incited falls through from the second filter screen plate 40 to the inside of the frame case 1. When the rice flour is dispersed, some larger particles are filtered by the second filter screen plate 40 and slide down to the inside of the storage tank along with the second filter screen plate 40, and finally, the particles remained in the storage tank are discharged from the slag discharge pipe 38. Not only the dispersing effect is good, but also the subsequent cleaning is convenient and fast.
The rice noodles fall into the frame box 1, slide along the slide plate 36 to the discharge opening 37, and are discharged from the discharge opening 37.
The primary filter mechanism 7 can be detached from the upper part of the frame box 1 for replacement according to actual requirements in use. The second electric telescopic column 21 contracts to push the end plate 2 to move along the sliding groove 4. During the installation, the flange 20 is installed in the inside of sliding tray 4, and clamp plate 18 presses at the upper portion edge of frame case 1, will just strain mechanism 7 and promote behind required position, and the electronic flexible post 21 of second extends downwards, drives push pedal and flange 20 butt, carries on spacingly to flange 20, and then makes whole just strain mechanism 7 stable in position. And the height of the loading compartment 16 can be adjusted according to the size of the loading compartment 16 and the middle frame 5 in use. When loading the height of case 16 and adjusting, first electronic flexible post 19 stretches out and draws back, can drive and load case 16 and move in vertical direction, adjusts simple swiftly, can adapt to different work demands.
