Description

Technical Field

[0001] The utility model relates to the field of aquatic feed production, in particular to a double-shaft conditioner. Background Art

[0002] At present, feed manufacturers generally use a single-shaft paddle conditioner for the ripening treatment of powder materials. Two identical devices are used in combination with a granulator to produce pellet feed. As a single-cylinder and single-shaft structure, since the volume of the cylinder cannot be made very large, the volume ratio is small. Coupled with the high rotational speed of the paddle shaft, the powder usually deviates to one side and moves forward. When steam is added into the cylinder, it is difficult to fully contact the powder. As a result, the conditioning effect is not good, and the residence time is usually only 1-2 minutes, which cannot meet the requirements in terms of ripening time. The ripening effect of the powder is poor, resulting in the water resistance of the pellets pressed by the ring die granulator not meeting the standard; ultimately, when farmers use this material for aquaculture products, the aquaculture effect is also not good. The unripened material is easy to disperse, easy to pollute the water quality, and the aquaculture harvest and expenditure are not proportional, with the risk of losses. Moreover, it is difficult for the single-shaft paddle conditioner to adjust the effect of flipping the feed according to the particle size of the feed. Summary of the Utility Model

[0036] A steering mechanism 6 for adjusting the orientation of the first stirring blade 4 is provided between the first stirring shaft 2 and the first stirring blade 4. The steering mechanism 6 includes a mounting hole 61 provided on the first stirring shaft 2, an insert 62 embedded in the mounting hole 61, an adjusting tooth 63 provided on the first stirring blade 4, and a cover 64 sleeved on the first stirring blade 4 and covering the insert 62. The adjusting tooth 63 is inserted into the insert 62 to limit the relative rotation between the two.

[0037] The utility model provides a double-shaft conditioner. The first stirring shaft functions as a feeding function, and the second stirring shaft functions as a return material function for flipping movement. The material can be flipped along with the first stirring blade and the second stirring blade, so that it can be in full contact with steam, and the conditioning effect is good. Through the steering mechanism, the orientation of the first stirring blade is adjusted. When conditioning large-particle feed, the inclination of the first stirring blade is lowered, so as to increase the residence time of the large-particle feed in the cylinder and strengthen the conditioning effect. On the contrary, when conditioning small-particle feed, the inclination of the first stirring blade is raised, so as to reduce the residence time of the small-particle feed in the cylinder and improve the efficiency.

[0038] Further, as a preferred implementation manner of this solution rather than a limitation, the mounting hole 61 includes an embedding groove 611 for the insert 62 to be embedded, and an insertion groove 612 provided at the bottom of the embedding groove 611 for the first stirring blade 4 to be inserted. The first stirring blade is inserted into the insertion groove, which increases the stress intensity of the first stirring blade and is not easily bent or disengaged. The insert is embedded in the embedding groove, and the two will not rotate relatively.

[0039] Further, as a preferred implementation manner of this solution rather than a limitation, the depth of the embedding groove 611 is half of the thickness of the insert 62. After the insert is worn, it is convenient to take out the insert for replacement.

[0040] Further, as a preferred implementation manner of this solution rather than a limitation, the included angle between two adjacent first stirring blades 4 is sixty degrees. The conditioning effect is better.

[0041] Further, as a preferred implementation manner of this solution rather than a limitation, the included angle between two adjacent second stirring blades 5 is sixty degrees. The conditioning effect is better.

[0042] Further, as a preferred implementation manner of this solution rather than a limitation, the distance between the first stirring shaft 2 and the second stirring shaft 3 is 320 mm. The conditioning effect is better.

[0043] Further, as a preferred implementation manner rather than a limitation of this solution, a cover hole 641 for the first stirring blade 4 to pass through is provided at the top of the sleeve cover 64, and a rubber ring 642 is provided on the top wall of the sleeve cover 64 and corresponding to the cover hole 641. The cover hole 641 is spaced from the first stirring blade 4, and the rubber ring 642 is located between the cover hole 641 and the first stirring blade 4. When the sleeve cover drives the rubber ring to slide along the support column, the feed adhered to the support column can be removed.

[0044] Further, as a preferred implementation manner rather than a limitation of this solution, the first stirring blade 4 includes a support column 41 extending out in the radial direction of the first stirring shaft 2, and a blade 42 provided at the end of the support column 41. A bayonet 411 for the blade 42 to be inserted is provided at the end of the support column 41.

[0045] Further, as a preferred implementation manner rather than a limitation of this solution, an external thread is provided on the sleeve cover 64, and an internal thread is provided on the mounting hole 61. The sleeve cover 64 is threadedly connected to the mounting hole 61 so that the sleeve cover 64 presses against the adjusting tooth 63 through the rubber ring 642. This can improve the sealing performance and prevent steam and moisture from entering the mounting hole.

[0046] The above are only the preferred embodiments of this application, and are not used to limit the scope of implementation of this application.
