Problems solved by technology

The waste generated during the start-up process usually weighs tens to hundreds of kilograms. It is necessary to design a separate process for conveying, storing, and processing the waste. Workers need to transport this part of the material to the waste disposal site, which is time-consuming and laborious.

Embodiment 1

[0038] The third rotating shaft 32 is provided with two groups of first helical blades symmetrically arranged left and right, and the helical directions of the two groups of first helical blades are opposite. In this embodiment, by arranging the two sets of first helical blades symmetrically, the material entering the third cylinder 31 from the third feed port can flow to the middle position of the third cylinder 31 through the first helical blades, and finally Discharge from the third outlet.

Embodiment 2

[0040] Such as Figure 5 As shown, the third rotating shaft 32 is provided with two sets of second helical blades 331 symmetrically arranged left and right and a plurality of third blades 332 arranged between the two sets of second helical blades 331 and aligned with the third discharge port. , the two sets of second helical blades 331 have opposite directions of rotation, a plurality of third blades 332 are arranged at equal intervals along the circumferential direction of the third rotating shaft 32 and the arrangement direction of the third blades 332 is in the same direction as the axial direction of the third rotating shaft 32 vertical. In this embodiment, by setting the helical directions of the second helical blades 331 on the left and right sides in opposite directions, the materials on both sides can flow to the third blades 332. Circumferentially equidistant arrangement and the arrangement direction of the third paddle 332 is perpendicular to the axial direction of ...

Embodiment 3

[0042] Such as Figure 6 As shown, the first end to the second end of the third rotating shaft 32 sequentially include a first conveying section, an intermediate section and a second conveying section, and the intermediate section includes a conveyor belt arranged on the third rotating shaft 32 and aligned with the third discharge port. A plurality of second intermediate paddles 323, the plurality of second intermediate paddles 323 are arranged at equal intervals along the circumferential direction of the third rotating shaft 32, the arrangement direction of the first paddles 321 is perpendicular to the axial direction of the third rotating shaft 32, the second A conveying section includes a plurality of first blades 321 arranged on the third rotating shaft 32, and the plurality of first blades 321 are arranged at intervals along the fourth helical direction, and the second conveying section includes a plurality of blades arranged on the third rotating shaft 32. The second pad...

Abstract

The invention provides an efficient quenching and tempering device and a quenching and tempering method thereof. The quenching and tempering method comprises the following steps: carrying out initialfeeding in a first feed opening in a pre-quenching and pre-tempering layer; starting a steam adding system and a quenching and tempering heat tracing system in the pre-quenching and pre-tempering layer and a quality preserving heat tracing system in a quality preserving layer, and simultaneously controlling a first rotating shaft to rotate in a forward direction and a reverse direction alternatelyto ensure that initially fed materials flow back and forth in a first cylinder body in the pre-quenching and pre-tempering layer; supplying steam to the first cylinder body through the steam adding system; monitoring the temperature of the materials in the first cylinder body through a first temperature sensor; when a quenching and tempering temperature is reached, controlling the first rotatingshaft to rotate normally, and carrying out feeding according to a normal feeding amount; increasing the steam addition amount, and controlling rotation of a second rotating shaft and a third rotatingshaft at the same time to ensure that the materials in the first cylinder body are uniformly discharged through a second cylinder body and a third cylinder body in sequence. By adopting the quenchingand tempering method in the invention, the emission of waste materials in a starting process can be reduced, the device can enter a normal production state quickly, and the labor intensity is reducedat the same time.

Description

technical field [0001] The invention relates to the technical field of grain and feed processing equipment, in particular to a high-efficiency conditioning device and a conditioning method thereof. Background technique [0002] Feed needs to be subjected to steam high-temperature tempering treatment on the material before pelleting. The equipment for conditioning treatment is called a conditioning device, which uses steam to sterilize the material at high temperature, eliminates the anti-nutritional factors in the material, improves the degree of maturity, and achieves excellent quality. breeding effect. During the tempering process, the small particles of the material absorb water, the core is softened, and the subsequent granulation will be easier. Temperature, moisture, and time are the three key indicators to measure the tempering effect. In order to achieve a good tempering effect, it is usually achieved by increasing the tempering temperature and prolonging the temper...
