DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 A corn flake cooling and screening device comprises a screening machine 1 and two support frames 2. A horizontal reciprocating screw 11 is provided between the two support frames 2 and is rotated by a driving motor. A screw sleeve 12 connected to the screening machine 1 is provided on the threaded sleeve of the horizontal reciprocating screw 11. The special-shaped structures of the two support frames 2 and the horizontal reciprocating screw 11 and other components realize stable support of the screening machine 1.

[0022] A pump liquid box 5 is installed on the support frame 2, and an active chamber 15 and a rotating chamber 16 are provided in the pump liquid box 5. Coolant is provided in the active chamber 15, and a vertical reciprocating screw 17 is rotatably provided in the rotating chamber 16. The vertical reciprocating screw 17 is connected to the horizontal reciprocating screw 11 through a transmission mechanism. A piston plate 20 is provided in the active chamber 15, and the piston plate 20 is connected to the vertical reciprocating screw 17 through a connecting mechanism. A drop pipe 7 is provided on one side of the screening machine 1 through a discharge pipe 4, and a cooling chamber 14 is provided in the drop pipe 7. The cooling chamber 14 is connected with the active chamber 15 through a liquid inlet pipe 8 and a circulation pipe 9. The cooling chamber 14 is designed in a spiral shape to increase the residence time of the coolant in the drop pipe 7 to ensure its heat absorption and cooling effect. At the same time, the drop pipe 7 can also be set to a spiral shape to ensure the residence time of the corn flakes therein, thereby improving the heat absorption and cooling effect.

[0023] The transmission mechanism includes a driving gear 6 arranged on the support frame 2 and connected to the horizontal reciprocating screw 11. The bottom wall of the pump liquid box 5 is provided with a transmission gear 18 connected to the vertical reciprocating screw 17. The driving gear 6 is meshed with the transmission gear 18. As shown in the accompanying drawings, the driving gear 6 and the transmission gear 18 in this scheme are both bevel gears, and the two are meshed with each other to realize the power transmission of the drive motor and the horizontal reciprocating screw 11.

[0024] The connecting mechanism includes a connecting frame 19 threadedly mounted on the vertical reciprocating screw 17. The connecting frame 19 is U-shaped and both ends are fixedly connected to the outer wall of the piston plate 20. The connecting frame 19 is U-shaped and both ends slide through the inner wall of the rotating chamber 16 and extend into the active chamber 15. Therefore, it has its own limit and will not rotate with the vertical reciprocating screw 17.

[0025] A limit rod 13 is provided between the two support frames 2. The limit rod 13 is designed to be parallel to the horizontal reciprocating screw 11. The limit rod 13 slides through the screw sleeve 12. The limit rod 13 realizes the limiting effect of the screw sleeve 12, which can prevent the screw sleeve 12 and the screening machine 1 connected to the screw sleeve 12 from rotating together with the horizontal reciprocating screw 11.

[0026] A first valve is provided in the liquid inlet pipe 8, and a second valve is provided in the circulation pipe 9. Both the first valve and the second valve are one-way valves. With the help of the first and second valves as one-way valves, the flow direction of the coolant is controlled so that it can only flow in one direction to complete the circulation.

[0027] A feed port is provided on the upper end face of the pump liquid box 5, and a sealing cover 10 is installed on the inner thread seal of the feed port. A heat sink is provided on the outer wall of one side of the pump liquid box 5. The sealing cover 10 can be disassembled and assembled to replace the coolant in the active cavity 15, and the heat sink can realize the cooling treatment of the coolant in the active cavity 15.

[0028] When the utility model is used, the driving motor drives the horizontal reciprocating screw 11 to rotate. When the horizontal reciprocating screw 11 rotates, the screw sleeve 12 on the outer wall drives the screening machine 1 to move horizontally and reciprocatingly. The materials entering the screening machine 1 through the feed hopper 3 are screened and processed. A slag discharge pipe is provided at the bottom of the screening machine 1 to discharge the broken small materials. The larger corn flakes enter the drop pipe 7 through the discharge pipe 4 and are finally discharged.

[0029] When the horizontal reciprocating screw 11 rotates, it can also drive the driving gear 6 to rotate, and the driving gear 6 can drive the transmission gear 18 to rotate. The transmission gear 18 can drive the vertical reciprocating screw 17 to rotate. When the vertical reciprocating screw 17 rotates, the connecting frame 19 of its outer wall can drive the piston plate 20 to move up and down in the active cavity 15. When the piston plate 20 rises, the coolant can be squeezed into the cooling cavity 14 through the liquid inlet pipe 8. When the piston plate 20 descends, the coolant in the cooling cavity 14 can be sucked back into the cooling cavity 14. The vertical reciprocating screw 17 continuously rotates to realize the circulating flow operation of the coolant, and the large pieces of corn flakes passing through the blanking pipe 7 can be subjected to heat absorption and cooling treatment.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
