Description

TECHNICAL FIELD

[0001] The present application relates to the field of wastewater treatment, in particular to a flocculation tank for potato protein extraction. BACKGROUND

[0002] In the processing of potatoes, the sliced potatoes are washed with water, and the waste water after washing contains a large amount of protein. In order to avoid waste, the waste water needs to be treated to extract the protein. In the process of waste water treatment, the heated waste water is introduced into the flocculation tank, and the waste water flows along the spiral coil in the tank, so that the protein molecules flocculate under mutual collision.

[0003] However, during the actual treatment of waste water, due to the radial centrifugal force generated by the spiral trajectory, the waste water flowing in the spiral coil has a phenomenon that the flow rate of the waste water on the outside is fast, and the flow rate of the waste water on the inside is slow. This phenomenon can cause the problem of insufficient collision frequency of protein molecules due to low flow rate and insufficient turbulence intensity on the inside, and the insufficient collision frequency directly affects the formation of protein flocculation, which seriously affects the flocculation effect.

[0014] 1.

By rotating the swing ear, the push disc frame can be moved to push the disc ear, and then drive the pipe moving disc to reciprocate and rotate at a small amplitude, so that the spiral coil reciprocates and rotates at a small amplitude. When the spiral coil changes direction, the wastewater in the spiral coil will immediately reverse due to its own viscous drag force, while the wastewater in the central region of the inner side of the spiral coil will not change its original motion direction due to inertia. Under the action of the above-mentioned wastewater lagging behind due to inertia, the wastewater in the spiral coil will produce local shear and vortex phenomenon, thereby pushing the wastewater in the inner side of the spiral coil outward and promoting it to fully contact and exchange with the wastewater outside the spiral coil, so as to improve the collision frequency of protein molecules in the wastewater and further promote the formation of protein flocculation, thereby further improving the flocculation effect.

[0016] 3. When the spiral coil reciprocates and rotates, the push wheel will be driven to roll on the push rail synchronously. When the push wheel rolls to the protruding position of the push rail, the piston cap will move towards the spiral coil to extend the push flow platform from the spiral coil. When the push wheel rolls to the recessed position of the push rail, the retraction spring will push the piston cap to move reversely, so that the push flow platform moves out of the spiral coil. In this way, the push flow platform reciprocates to avoid occupying the space in the spiral coil and affecting the flow of wastewater, thereby ensuring the normal flow of wastewater.

[0035] When the wastewater containing potato juice is flocculated, the wastewater is heated and then injected into the spiral coil 10 through the water inlet pipe 4 to flow and flocculate in the spiral coil 10. In this process, the push flow slope of the push flow table 19 guides the wastewater flowing on the inner side edge of the spiral coil 10 to move outward and fully contact and exchange with the wastewater flowing on the outer side edge of the spiral coil 10 to increase the collision frequency of protein molecules in the wastewater and promote the formation of protein flocculation.

When the spiral coil 10 changes direction, the wastewater on the wall of the spiral coil 10 immediately reverses due to its own viscous drag, and the wastewater in the central region of the inner side of the spiral coil 10 cannot change the original motion direction synchronously due to inertia. Under the action of the above-mentioned inertia lag of the wastewater, the wastewater in the spiral coil 10 produces local shear and vortex phenomenon, thereby pushing the wastewater on the inner side of the spiral coil 10 outward and promoting it to fully contact and exchange with the wastewater on the outer side of the spiral coil 10 to increase the collision frequency of protein molecules in the wastewater and further promote the formation of protein flocculation. The flocculated wastewater is discharged through the water outlet pipe 5 to wait for the next process of separation. At the same time, in the above process, when the spiral coil 10 reciprocates, the push wheel 22 is driven to roll on the push rail 23 synchronously. When the push wheel 22 rolls to the protruding position of the push rail 23, the piston cap 18 moves towards the spiral coil 10 to extend the push flow table 19 from the spiral coil 10. When the push wheel 22 rolls to the recessed position of the push rail 23, the retraction spring 20 pushes the piston cap 18 to move reversely, so that the push flow table 19 moves out of the spiral coil 10. The above-mentioned reciprocation avoids the phenomenon that the push flow table 19 always extends to occupy the space in the spiral coil 10 and affects the flow of the wastewater. In this way, the normal flow of the wastewater is ensured.
