Embodiment Construction

[0028] The following is further described in detail through specific implementation methods:

[0029] The reference signs in the drawings of the description include: feed hopper 1, material guide plate 2, cleaning frame 3, Venturi tube 4, dust inlet 5, exhaust hood 6, screen 7, swing rod 8, fan-shaped disc 9, Rice outlet 10, dust collection box 11, impeller 12, filter cloth 13.

[0030] The embodiment is basically as attached figure 1 Shown: the vibrating cleaning sieve for rice sifting includes a cleaning frame 3 and a vibrating motor with an inclined bottom, and the left end of the cleaning frame 3 is the high end of the cleaning frame 3 bottom wall. In the cleaning frame 3, a screen cloth 7 is inclinedly arranged, and the screen cloth 7 is slidably connected in the cleaning frame 3. The angle of inclination of the screen cloth 7 is consistent with the bottom wall of the cleaning frame 3. The vibration motor is used to drive the vibration of the screen cloth 7. The vibratio...

Abstract

The invention belongs to the field of rice processing, and particularly relates to a vibration cleaning screen for rice screening. The vibration cleaning screen for rice screening comprises a cleaningframe and a dust removal unit, wherein an inclined screen is arranged in the cleaning frame, an impurity outlet is arranged in the cleaning frame at the lower end of the screen, and a rice outlet isarranged in the bottom wall of the cleaning frame; the dust removal unit comprises a Venturi tube, the dust removal unit also comprises a gas storage device for introducing high-pressure gas into theVenturi tube, and the Venturi tube comprises a necking section and a flaring section communicated with two ends of the necking section; the flaring section of the Venturi tube, close to the high end of the screen, is an air inlet end; a dust inlet is arranged on the side wall of the necking section of the Venturi tube, an air inlet one-way valve is arranged in the dust inlet, and a collecting unitfor collecting dust is arranged at the flaring section of the Venturi tube, close to the lower end of the screen. By adopting the scheme of the invention, the dust impurities generated in the vibration cleaning process of the rice can be absorbed and treated, and the influence of the dust on the processing environment is avoided.

Description

technical field [0001] The invention belongs to the field of rice processing, and in particular relates to a vibrating cleaning sieve for rice screening. Background technique [0002] The rice processing process includes steps such as screening, stone removal, magnetic separation, hulling, paddy separation, rice milling, color sorting, polishing, and packaging. Screening refers to the removal of impurities in the rice. Vibration cleaning is usually used in the prior art. sieve to filter. The vibrating cleaning sieve includes a cleaning frame, which is vertically slid and connected with two layers of inclined screens. The aperture of the lower screen is smaller than that of the upper screen. The vertical sliding of the two layers of screens causes the screens to vibrate. Larger impurities such as stones roll along the slope of the upper screen and are discharged through the impurity outlet on the side wall of the cleaning frame; rice passes through the upper screen and falls...
