Description

Technical Field

[0001] The utility model relates to the technical field of devices for cottonseed protein production, in particular to a draining device for cottonseed protein production. Background Technique

[0002] Cottonseed protein is the protein in cottonseed cake after extracting oil from cottonseed kernels. It is a high-protein product made by ginning, shelling cottonseeds, then soaking in oil at low temperature once, draining, and removing gossypol from it. It is a good protein food and protein source for animal feed. During the production process of cottonseed protein, a draining device will be used to drain the oil from the oil-soaked cottonseeds to facilitate subsequent gossypol removal operations.

[0003] When the existing draining device for cottonseed protein production is in use, generally, the cottonseeds are drained by centrifugation or compression. Taking centrifugal draining as an example, after the cottonseeds are put into the centrifugal cylinder, the motor drives the centrifugal cylinder to rotate to generate centrifugal force, and the oil will be thrown out of the centrifugal cylinder and flow down along the inner wall of the machine shell for discharge, so as to accelerate the separation of the oil from the cottonseeds. However, since the centrifugal cylinder is arranged inside the machine shell, the operation of taking out the drained cottonseeds is rather cumbersome, which causes inconvenient feeding. At the same time, some cottonseed debris will be mixed in the drained oil, affecting the recycling of the oil and being not conducive to the long-term use of the draining device.

[0027] The drainage assembly 10 includes a liquid outlet 101 arranged at the bottom of the collecting cylinder 2. The bottom of the inner cavity of the collecting cylinder 2 is designed in a funnel shape. The bottom of the liquid outlet 101 is connected with a drain elbow 102. An electromagnetic valve is installed inside the drain elbow 102. During actual use, it can be pre-connected to an external oil storage mechanism through the drain elbow 102. When the oil falls to the bottom of the inner cavity of the collecting cylinder 2 with a funnel-shaped design, it will quickly gather towards the liquid outlet 101. By opening the electromagnetic valve inside the drain elbow 102, it is convenient for the drained oil to be discharged and collected.

[0028] Working principle: First, the staff pours the cotton seeds to be drained into the interior of the centrifuge cylinder 4. Then, the first motor 68 is started, and the first sprocket 66, the second sprocket 67, and the transmission shaft 611 are used to drive the centrifuge cylinder 4 to rotate. The centrifugal force generated during rotation will accelerate the separation of the oil liquid from the cotton seeds. The drained oil liquid will fall into the interior of the filtering assembly 9. After being filtered, it will be collected through the drainage assembly 10 and enter the external oil storage mechanism, thereby keeping the drained oil liquid clean and facilitating the subsequent recycling work of the oil liquid. After the oil draining work is completed, the second transmission assembly 8 can drive the entire centrifuge cylinder 4 to displace along the outer side of the gear ring 85 with the circular boss 81 as the center, so as to move the centrifuge cylinder 4 to a side away from the collection cylinder 2. Then, a trolley is arranged below the centrifuge cylinder 4 and the opening and closing assembly 7 is used to take out the drained cotton seeds, thereby facilitating the loading and unloading operation of the cotton seeds, saving time and effort, and also facilitating the cleaning of the centrifuge cylinder 4 after long-term work.
