Example 1

A kind of peanut processing pipeline disclosed in this embodiment will be further described below in conjunction with accompanying drawings 1-18;

First, the adsorption multi-stage screening peanut cleaning system is introduced. Referring to Figure 2, the adsorption-type multi-stage screening peanut cleaning system includes a first feeding device I-01, a winnowing mechanism I-02, a vibrating screening mechanism I-03 and a first frame I-04. The first feeding device I-01 is located at the side of the air-selecting mechanism I-02 and the vibrating screening mechanism I-03, and the air-selecting mechanism I-02 is located above the vibrating screening mechanism I-03.

The first feeding device I-01 is fixed on the first frame I-04 through its internal drive drum external bearing support, and the air selection mechanism I-02 is fixed on the positive pressure fan fixing bracket I-04 through fixing bolts. The selection mechanism adsorbs and cleans the residual peanut stems and leaves in the material, and the residual peanut stems and leaves are adsorbed from the adsorption pipeline I-0203 under the action of the positive pressure fan I-0202. The adsorbed material falls into the primary screen I-0302 of the vibrating screening mechanism I-03. The screen support disc I-0310 in the vibrating screening mechanism is connected to the supporting disc bottom plate on the first frame through fixing bolts to fix the vibrating screening mechanism on the first frame, and the materials are respectively in the first-stage screen mesh I- 0302, the secondary screen I-0305, the tertiary screen I-0308 are screened, and the discharge port I-0304, the first discharge port I-0307, and the second discharge port of the first screen are respectively screened. I-0309 is discharged to complete the screening process.

The first feeding device I-01 is driven by a stepping motor, and drives the drive drum to rotate through the deceleration of the pulley. The transmission roller drives the conveyor belt and the feeding hopper on it to carry out digging intermittent feeding of materials. When the hopper drives the material to the top of the first feeding device, the material is thrown into the sliding plate I-0201 of the adsorption mechanism. The inclined angle of the sliding plate is θ=26.1°-33.02° to ensure that the material is only under the action of gravity and friction. able to slide down on its own.

Referring to Figure 3, the adsorption structure is composed of adsorption pipeline I-0203, positive pressure fan I-0202 and slide plate I-0201 designed based on the principle of Laval tube. The adsorption pipeline designed based on the principle of Laval tube can use a positive pressure fan to generate negative pressure suction. The design of the adsorption pipeline can ensure that impurities are removed along the pipeline and avoid damage to peanuts caused by direct adsorption by the fan. The adsorption pipe is mainly composed of a reducing pipe, an expanding pipe and an outlet pipe. The principle of negative pressure adsorption in the adsorption pipe is: the reducing pipe shrinks to the Adam’s apple, the cross-sectional area gradually decreases, and the airflow generated by the positive pressure fan gradually accelerates; the expansion pipe starts from the Adam’s apple. The cross-sectional area is gradually increased, and the airflow can continue to accelerate at this time. Without considering the gravitational potential energy, the higher the wind velocity, the smaller the wind pressure, so the wind pressure at the Adam’s apple is lower than the outside atmospheric pressure, and the wind pressure gradually decreases in the expansion tube. The pressure at the Adam's apple is lower than the pressure value in the outstretched tube, which has a certain suction effect on the airflow in the tube, and a negative pressure is formed in the tube at this time.

Referring to Figure 4, the vibration screening mechanism I-03 is driven by two vibration motors, and the vibration motors drive the three-stage screen to screen the materials as a whole. The relative angle between the shafts of the two vibrating motors is 40°, which drives the vibrating screening mechanism to vibrate in a compound rotation. Each level of screen is connected with a discharge port, which is convenient for the screened materials to fall into the next process. After the material slips from the slide plate I-0201, it is carried by the sliding baffle and falls into the primary screen mesh I-0302. After screening, impurities larger than peanut pod particles are filtered out, and the impurities are discharged from the discharge port I of the primary screen mesh. -0304 slips into the first receiving box, peanut pods, peanut shriveled fruit and small particles of impurities fall into the secondary screen I-0305. The peanut pods are filtered out through the secondary screen I-0305. The peanut pods slide out from the first discharge port I-0307 for collection, and the peanut shriveled fruit and small particles of impurities fall into the third-level screen I-0308. middle. After the sieving of the third-level screen I-0308, small particles of impurities are filtered out. The impurities fall from the third-level screen and are collected by the collection hopper and then fall into the material box. The peanuts fall from the third-level screen. The second discharge port I-0309 completes the cleaning of materials. Spring support is used between the screens of each stage to buffer and absorb vibration, so that the screening device is inclined too much in a certain direction. The whole vibrating screening device is fixed above the first frame through the screen support spring I-0310 at the bottom.

Each screen is inclined at a certain angle: the inclination angle of the first and third screens is 0-5°; the second screen is the main screen layer, referring to the inclination angle of the slide, so the inclination angle of the screen in this layer is is θ=26.1°-33.02°. The amplitude of the vibration motor is λ=2.5mm, the vibration frequency is 22Hz, the vibration direction angle is β=30°-60°, and the throwing index D=4.9. Establish the three-axis size of peanuts, measure the size data of peanuts according to the experimental method, and determine the 25×15mm oval plane punching screen for the primary screen I-0302, and the ellipse of 17×6mm for the secondary screen I-0305 Shaped flat punching screen. The three-stage sieve I-0308 selects an 8mm circular plane punching sieve. There are baffles around each layer of screen to prevent materials from being thrown out during the screening process.

After the shells are broken by the screw shell breaking device II-02, the peanut shells and peanut kernels are separated in the first negative pressure adsorption device II-03.
