Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of refrigeration equipment, and relates to a placing refrigerator, in particular to a placing refrigerator for pellet production. BACKGROUND

[0002] In the pellet production process, the freezing link has a significant influence on product quality and production efficiency, but direct freezing of the pellets can easily lead to uneven freezing, and further cooling is needed, and the pellets need to be quickly cooled and pre-cooled to dissipate the internal heat of the pellets and avoid the generation of a large amount of ice crystals in the pellets, thereby causing poor freezing effect of the pellets.

[0003] Traditional pellet pre-cooling equipment often has many problems: the degree of automation is low, and manual operation is needed in the processes of pellet feeding, distribution and tray transfer, which not only has low efficiency, but also can easily cause damage to the pellets due to improper human operation, and the pellets are prone to accumulation and adhesion, which affects subsequent freezing and product integrity.

[0004] Therefore, we propose a placing refrigerator for pellet production, which can distribute the pellets and adaptively adjust according to the specifications of the pellets to meet the placing needs of pellets of different specifications, can turn over the pellets, facilitate separated conveying and placing, can spiral convey the pellets, quickly cool and pre-cool the pellets during conveying, reduce the internal heat of the pellets, facilitate subsequent freezing, avoid excessive internal ice crystals, can convey the pellets, and can temporarily place or convey the pellets out according to processing needs.

[0067] In the embodiment, when producing different size specifications of pellets, the device needs to be adjusted. The output shaft of the driving motor three drives the double-threaded screw to rotate, which drives the two connecting rods two 36 to move towards the middle, and the two outermost shunt plates 33 and the outermost partition plates 31 are driven by the two connecting rods two 36 to move towards the middle position. The outermost shunt plate 33 pushes the adjacent inner shunt plate 33 through the limiting spring one, and the adjacent inner shunt plate 33 pushes the more inner shunt plate 33 in turn. The outermost partition plate 31 pushes the adjacent inner partition plate 31 through the limiting spring two, and the adjacent inner partition plate 31 pushes the more inner shunt plate 33 in turn, thereby realizing synchronous adjustment and facilitating the adaptation to the production needs of different size specifications of pellets. Moreover, during the adjustment, the rotating guide plates 26 on both sides are always aligned with the shunt plates 33 on the same side, which facilitates the diversion of the pellets after adjustment.

[0068] The pellets conveyed by the conveyor one 3 are guided to the middle through the rotating guide plates 26 on both sides and are shunted through the shunt plates 33. The conveyed pellets enter the shunt channels and are in contact with the turnover mechanism 4 through the shunt channels. After the same turnover by the turnover mechanism 4, the pellets are conveyed into the diversion channel and flow into the material conveying disc 17 on the spiral conveying belt 19 from the diversion box 30. The pellets are separated and placed on the corresponding material conveying disc 17 in batches.

During turnover, the arc-shaped stop blocks 39 are in contact with the pellets. After turnover, the scoop opening of the turnover scoops 56 rotates and is lower than the upper end surface of the conveying belt of the conveyor one 3. At this time, a plurality of pellets synchronously fall into the grooves 38 of the corresponding turnover scoops 56. The size of the groove 38 can only accommodate one pellet, so other pellets cannot simultaneously enter the same turnover scoop 56. Moreover, during turnover, the arc-shaped stop blocks 39 turn back and block other pellets from falling down, thereby realizing the separated and batched conveying of the pellets. During turnover, the rear end of the turnover scoops 56 is in contact with the diversion channel of the corresponding diversion box 30. The pellets roll into the corresponding diversion channel from the groove 38 and are conveyed into the corresponding material conveying groove of the material conveying disc 17 from the diversion channel.
