Example 1

The peanut processing line disclosed in the embodiment is further described with reference to the accompanying drawings 1-18;

firstly, an adsorption type multi-stage screening peanut cleaning system is introduced. Referring to the attached figure 2, the adsorption type multi-stage screening peanut cleaning system comprises a first feeding device I-01, a winnowing mechanism I-02, a vibration screening mechanism I-03 and a first frame I-04. The first feeding device I-01 is located on the side of the air separation mechanism I-02 and the vibrating screening mechanism I-03, and the air separation mechanism I-02 is located above the vibrating screening mechanism I-03.

The first feeding device I-01 is fixed on a first rack I-04 through a transmission roller external bearing support inside the first feeding device I-01, the air separation mechanism I-02 is fixed on a positive pressure fan fixing support I-04 through a fixing bolt, the air separation mechanism carries out adsorption cleaning on residual peanut stems and leaves in the material, and the residual peanut stems and leaves are adsorbed out of an adsorption pipeline I-0203 under the action of a positive pressure fan I-0202. The adsorbed material falls into a first-stage screen I-0302 of a vibrating screening mechanism I-03. A screen mesh supporting disc I-0310 in the vibration screening mechanism is connected with a supporting disc bottom plate on a first frame through a fixing bolt to fix the vibration screening mechanism on the first frame, materials are screened in a first-level screen mesh I-0302, a second-level screen mesh I-0305 and a third-level screen mesh I-0308 respectively, and discharged from a first-level screen mesh discharge port I-0304, a first discharge port I-0307 and a second discharge port I-0309 respectively, and the screening process is completed.

The first feeding device I-01 is driven by a stepping motor and drives a transmission roller to rotate through the speed reduction of a belt wheel. The transmission roller drives the conveying belt and the feeding hopper on the conveying belt to carry out digging type intermittent feeding on the materials. When the hopper drives the material to convey to the top of the first feeding device, the material is thrown onto an I-0201 slide carriage of the adsorption mechanism, and the inclination angle of the slide carriage is 26.1-33.02 degrees, so that the material can automatically slide downwards only under the action of gravity and friction force.

Referring to attached figure 3, the adsorption structure is composed of an adsorption pipeline I-0203 designed based on the Laval tube principle, a positive pressure fan I-0202 and a slide carriage I-0201. The adsorption pipeline designed based on the Laval pipe principle can use the positive pressure fan to generate negative pressure suction, and the design of the adsorption pipeline can ensure that impurities are cleaned along the pipeline, so that the damage to peanuts caused by direct adsorption of the fan is avoided. The adsorption pipeline mainly comprises a reducing pipe, an expansion pipe and a leading-out pipe, and the adsorption pipeline carries out negative pressure adsorption according to the principle that: the reducing pipe is contracted to a laryngeal knot, the area of the cross section is gradually reduced, and the airflow generated by the positive pressure fan is gradually accelerated; the cross-sectional area of the expansion pipe is gradually increased from the laryngeal prominence, and the airflow can continue to accelerate at the moment. Under the condition of not considering gravitational potential energy, the higher the flow velocity of wind, the smaller the wind pressure is, so that the wind pressure at the throat is smaller than the external atmospheric pressure, and the wind pressure is gradually reduced in the expansion pipe. The pressure at the throat junction is lower than the pressure in the outer extension pipe, a certain suction effect is generated on the gas flow in the pipe, and negative pressure is formed in the pipe.

The relative included angle between the rotating shafts of the two vibrating motors is 40 degrees, and the vibrating screening mechanism is driven to perform repeated rotation type vibration.

After the materials slide up from the slide carriage I-0201, the materials are accepted by the sliding baffle and fall into the first-stage screen I-0302, impurities larger than peanut pod particles are filtered out through screening, the impurities slide into the first material receiving box from a discharge port I-0304 of the first-stage screen, and the peanut pod, the flat peanut and small particle impurities fall into the second-stage screen I-0305. Peanut pods are filtered out through the screening of the second-stage screen I-0305, the peanut pods slide out of the first discharge port I-0307 and are collected, and shrunken peanuts and small particle impurities fall into the third-stage screen I-0308. The small particle impurities are filtered out through the screening of the three-stage screen I-0308, the impurities fall into the bin after being collected by the collecting hopper after falling from the three-stage screen, and the shrunken peanuts fall into the second discharge port I-0309 through sliding from the three-stage screen to finish the cleaning work of the materials. The screen meshes of each stage are supported by springs, so that the vibration is buffered and absorbed, and the screening device is excessively inclined towards a certain direction. The whole vibrating screen device is fixed above the first frame through screen mesh supporting springs I-0310 at the bottom.

Each screen is inclined at a certain angle: the inclination angle of the first and third grade screens is 0-5 degrees; the secondary screen is a main screening layer, and the inclination angle of the secondary screen is 26.1-33.02 degrees by referring to the inclination angle of the slide carriage. The amplitude of the vibration motor is 2.5mm, the vibration frequency is 22Hz, the vibration direction angle is 30-60 degrees, and the throwing index D is 4.9. Establishing three-axis dimensions of peanuts, and determining that the first-stage screen I-0302 selects an oval plane punching screen with the size of 25 multiplied by 15mm and the second-stage screen I-0305 selects an oval plane punching screen with the size of 17 multiplied by 6mm according to dimensional data of the peanuts measured by an experimental method.
