Description

Technical Field

[0001] The invention relates to the technical field of starch processing, in particular to a clarification and recovery device for starch processing. Background Art

[0002] In addition to being edible, starch can be used industrially to make dextrin, maltose, glucose and alcohol, etc. It has a wide range of applications and can usually be obtained from materials with high starch content such as corn, sweet potatoes, potatoes and kudzu root. The preparation steps of starch include washing, peeling, crushing, soaking, separation, clarification, dehydration and drying of the raw materials, among which clarification is the precipitation, stirring and other treatments of the separated starch slurry to remove impurities and insoluble substances, and to allow the starch to sink and the water to separate out.

[0003] Since the starch slurry contains a large amount of water, the water precipitated above the starch after precipitation is the clarified liquid, and the floating foam impurities condense above the clarified liquid. In order to reduce water consumption during starch processing, the clarified liquid is usually recycled to make starch processing more energy-saving and environmentally friendly.

[0004] However, the existing clarified liquid recovery device directly sucks and recovers the clarified liquid precipitated above the starch layer, and does not have the function of removing the floating foam before that, so that the floating foam impurities are also recovered when the clarified liquid is recovered, which affects the water quality of the clarified liquid and increases the workload of subsequent filtration of the clarified liquid.

[0016] 1. The clarification and recovery device for starch processing is provided with a froth removal mechanism. After starch precipitation is completed, the starch is sequentially divided into a clarified liquid layer and a froth layer. The fixed seat is driven downward by the first lifting cylinder, and the fixed seat drives the froth collection box to be inserted into the starch precipitation box until the opening on the froth collection box contacts the froth layer. The rotating shaft is driven to rotate by the rotating motor, and the rotating shaft drives the froth collection box to move slowly in the starch precipitation box, so that the froth layer enters the froth collection box from the opening and is collected, thereby achieving the effect of automatically removing the froth before the clarified liquid is recovered, and preventing the froth from affecting the water quality of the clarified liquid.

[0017] 2. The clarifying and recovering device for starch processing is provided with a clarified liquid recovery mechanism. The second lifting cylinder drives the connecting frame to move downward. The connecting frame drives the pressing plate to move downward and insert into the starch precipitation box through the center seat. During the pressing process of the pressing plate, the clarified liquid passes through the filter screen and flows to the top of the pressing plate. The water pump is started to suck the water pumping cavity through the pumping bellows, so that the suction hole generates negative pressure to suck the clarified liquid on the pressing plate. The clarified liquid is pumped into the clarified liquid collection box through the recovery pipe for collection. After the pressing plate is pressed on the starch layer, the starch and the clarified liquid are separated by the filter screen, and the clarified liquid is fully recovered.

[0018] 3. The clarification and recovery device for starch processing is provided with a first lifting cylinder and a second lifting cylinder. In the process of removing the froth and recovering the clarified liquid, the first lifting cylinder drives the froth collecting box to be inserted into the starch collecting box, and the second lifting cylinder drives the pressing plate to be inserted into the starch collecting box. The depths of the froth collecting box and the pressing plate inserted into the starch precipitation box are controllable, and the device can be used for recovering starch layers and clarified liquid layers of different thicknesses, and for cleaning froth layers of different thicknesses.

[0019] 4. The clarification and recovery device for starch processing is provided with a turning seat, a turning shaft and a turning motor. After the froth is removed from the froth collecting box, the froth impurities are inside the froth collecting box. The turning motor drives the turning shaft to rotate, and the turning shaft drives the turning seat to rotate. The turning seat drives the froth collecting box to turn 120 degrees to the left via the rotating shaft, so that the opening of the froth collecting box faces downward, which is convenient for pouring out the froth impurities in the froth collecting box.

[0031] Specifically, the froth collecting box 68 is in the shape of a hollow box with an inverted L-shape in longitudinal section. The bottom of the froth collecting box 68 is an isosceles trapezoid, which is used to reduce the contact area between the bottom of the froth collecting box 68 and the clarified liquid when the froth collecting box 68 rotates around the rotating shaft 66, thereby reducing the agitation of the clarified liquid.

[0035] Furthermore, the pressing plate 101 is circular, and the outer diameter of the pressing plate 101 is adapted to the inner diameter of the starch precipitation box 3. The pressing plate 101 is movably connected to the starch precipitation box 3. The connecting frame 108 is driven downward by the second lifting cylinder 9, and the connecting frame 108 drives the pressing plate 101 to move downward and be inserted into the starch precipitation box 3 through the center seat 104.

[0036] Furthermore, the clarified liquid below the filter screen 102 passes through the filter screen 102 and is connected to the through groove 103. There are a plurality of water absorption holes 106, which are equidistantly arranged circumferentially along the outer wall of the center seat 104. The pumping chamber 105 is connected to the through groove 103 through the water absorption holes 106. When the pressing plate 101 is pressed downward, the clarified liquid passes through the filter screen 102 and flows to the top of the pressing plate 101, so that there is clarified liquid in the through groove 103, the water absorption holes 106 and the pumping chamber 105.
