Problems solved by technology

For example, the pulverizer used in the fine grinding process after drying is generally operated in a clean air room with a general-purpose pulverizer. This kind of pulverization device has many insurmountable defects such as: when the powdery material blocks the screen in the feeding port, it will Cause the powdery material to float rapidly from the feed port to everywhere in the room, and the whole environment is destroyed
When the two-stage pulverizer is used, the first-stage discharge is not smooth, the motor of the pulverizer will be overloaded, and the motor will be burned; while the existing pulverizer uses a single air inlet, resulting in unbalanced wind pressure and air volume, and often materials are ejected or blown out. The screen is clogged, which affects the environment and cannot produce normally

Embodiment 1

[0048] Example 1: When the system enters the working state, the material volume is 3m³ / h. Adjust P1=2500m³ / h, P2=500m³ / h, P3=1800m³ / h, P4=1600m³ / h, the primary and secondary crushing motor currents are 48A and 50A respectively, both of which are less than the rated current of 60A, and there is no overflow at the suction port powder situation.

Embodiment 2

[0049] Example 2: When the system enters the working state, the material volume is 3m³ / h. Adjust P1=3000m³ / h, P2=500m³ / h, P3=1500m³ / h, P4=1400m³ / h, the primary and secondary crushing motor currents are 62A and 55A respectively, exceeding the rated current of 60A, the motor is overloaded, and the suction port is not Powder spillage occurs.

Embodiment 3

[0050] Example 3: When the system enters the working state, the material volume is 3m³ / h. Adjust P1=1600m³ / h, P2=1600m³ / h, P3=1600m³ / h, P4=1600m³ / h, the primary and secondary crushing motor currents are 45A and 43A respectively, both of which are less than the rated current of 60A. There is powder overflow at the suction port of the stage crushing. When the material is sucked by negative pressure, the air flow at the P1, P2, P3, and P4 air collection places plays a vital role in the transmission. The adjustment of each air volume accounts for the total air volume through statistical optimization. : P1 accounts for about 4 / 10, P2 accounts for about 1 / 10, P3 accounts for about 3 / 10, and P4 accounts for about 2 / 10. The above-mentioned structural scheme is adopted for realizing the adjustable air volume.

[0051] For the relevant parameters in the above three embodiments, see the embodiment summary table for details.

Abstract

The invention discloses a rice protein negative pressure series crushing and sucking device. The device comprises a crushing machine, a fan and a discharging bin. The crushing machine comprises a primary crusher and at least one secondary crusher, and the primary crusher and the secondary crushers are connected through communicating vessels. A collecting hopper is arranged on the primary crusher. The fan, the discharging bin and the secondary crushers are sequentially connected through pipelines. On the basis of the method, a matched using method is provided, that is, air and materials are completely separated in the whole device in a negative pressure state under the action of the fan and the crushing machine. The device and the using method has the beneficial effects that the requirements that materials are not sprayed out, blockage is avoided, the environment is protected, and the working efficiency is improved in the crushing process of industrial production can be met, and the effects of reasonably adjusting the sucking strength and free of any pollution can be achieved.

Description

technical field [0001] The present invention relates to the technical field of general physical or chemical methods or devices, in particular to the technical field of rice deep processing, and specifically refers to a rice protein negative pressure series crushing and suction device and its use method. Background technique [0002] At this stage, rice protein extraction and processing has become an industry, and many new processing equipment have been formed in the production process. For example, the pulverizer used in the fine grinding process after drying is generally operated in a clean air room with a general-purpose pulverizer. This kind of pulverization device has many insurmountable defects such as: when the powdery material blocks the screen in the feeding port, it will The powdery material is caused to float quickly from the feed port to various places in the room, and the entire environment is destroyed. When the two-stage pulverizer is used, the first-stage dis...
