Background

Along with the lack of rural labor force, the environmental protection of the starch industry production improves the emission requirement, and the adjustment of the rural agricultural industry structure leads to the reduction of crops which are planted in a centralized and large-area manner to generate starch, and can not provide sufficient raw materials for the large-scale starch industry.

The crops for producing starch comprise sweet potatoes (also called sweet potatoes, sweet potatoes and sweet potatoes), potatoes, lotus roots, sweet potatoes, cassava, kudzuvine roots, lotus roots and the like, the crop is very high in adaptability, simple in planting technology, suitable for fresh sales in seasons, long in storage and preservation time and easy to rot and deteriorate, the residual residues can be used as feed or stacked microbial humus to be used as organic fertilizer for returning to fields.

The traditional method for extracting and processing starch by farmers comprises the steps of manual grinding, machine crushing, manual filter cloth rack adding and swing filtering, wherein starch slurry is deposited, clear water is arranged on the upper surface, starch is arranged on the lower surface, and the clear water on the upper surface is discharged to leave the starch. This conventional method consumes a lot of labor and processing time (150 kg is processed by two persons in 8 hours in general), and thus a suitable machine capable of separating slurry from slag at one time and simple to operate is highly demanded.

The utility model provides a chinese patent of CN202011272620.2 discloses a sweet potato sediment thick liquid separating centrifuge, including frame, crushing room, crushing roller, sediment thick liquid separator and transmission, crushing room sets up on the frame, crushing room front side adds and is equipped with the drum, sediment thick liquid separator includes pivot, helical blade, brush cleaner and filter screen section of thick bamboo, brush cleaner, helical blade set gradually in the pivot, the brush cleaner evenly sets up in the multiunit, every two brush cleaner of group, the brush cleaner sets up in the drum, helical blade sets up in the vermicelli is indoor, crushing roller sets up in the crushing room of helical blade top, the filter screen section of thick bamboo cover is established outside the brush cleaner, is located the drum, distance between brush cleaner and the pivot increases gradually, pivot and crushing roller are connected with transmission. Compared with the sweet potato residue-pulp separation device of the traditional sweet potato residue-pulp separation machine, the sweet potato residue-pulp separation device has the advantages that the residue-pulp separation is cleaner, and the main shaft is more stable in operation.

Starch raw material enters the crushing cavity 301 through the feed hopper 6 and the material inlet 307, the crushing roller 210 in the crushing cavity 301 crushes the starch raw material, and crushed pulp slag is conveyed into the separation cavity 302 through the spiral auger 212.

In the separation cavity 302, the pulp and slag crushed materials mixed with water are swept by the rotating brush 203 in the inner cylinder 101 in a circulating manner, so that the crushed materials are fully dispersed on the filter screen 102 at the pulp filtering holes 105. The rotating brush 203 continuously sweeps, so that the starch slurry permeates outside the separating drum 1 through the filter screen 102 and is discharged through the slurry outlet 308, while the solid residue remains in the separating drum 1 and is conveyed to the starch residue outlet 107 through the spiral conveying channel 204, and finally is discharged from the slag outlet 309, so as to achieve the purpose of separating the slurry from the residue.

When the separating tube 1 needs to be disassembled, the nut on the connecting and fixing rod 313 at the second mounting plate 306 is disassembled firstly, then the second mounting plate 306 is disassembled, then the separating cavity shell 305 is pulled outwards, and finally the nut at the separating tube mounting rod 112 and the first mounting plate 304 is disassembled, so that the separating tube 1 can be disassembled.

After the additional filter screen 102 is attached after removal, the filter screen 102 is clamped by the two-half screen ring jacket 109, and the first bolts 111 are attached.

When the separation cavity 302 and the feed hopper 6 need to be washed, the washing pipe 7 is connected with a tap water pipe, and washing water enters the separation cavity 302 from a plurality of water outlets 312 at the top end of the separation cavity 302 after passing through a water inlet pipe mounting port 310 and a water inlet channel 311 on one hand, so that slurry slag in the front and back and middle of the separation cavity 302 is washed in all directions; the washing water enters the buffer force reducing chamber 314, and then enters the pulverizing roller 210 of the pulverizing chamber 301, and washes the pulverizing roller 210.
