Refined cotton is of cotton cellulose material prepared by using a cotton linter as raw material to pass through the main processes such as opening, pretreatment, alkali treating, boiling, bleaching, squeezing and dehydrating, drying and so on, and mainly used to produce cellulose of ether, nitrification and acetate. Such material is widely applied in many fields such as food, medicine, chemicals for daily use, plastics, electronics, papermaking, metallurgy, aerospace and so on, known as a special industrial gourmet powder.
Squeezing and dehydrating is an important stage after the bleaching process, and functions mainly to raise drying efficiency and reduce heat energy needed for drying. At present, the devices for squeezing and dehydrating mostly take a mesh belt as conveyor and a pressure roller for squeezing and dehydrating, but such dehydration method cannot achieve complete dehydration, and the refined cotton done by squeezing and dehydrating still contains a large amount of water, therefore such dehydration method not only affects subsequent drying efficiency, but also makes against the control of energy consumption during drying.
The objective of the present invention is to achieve a good dehydration effect and conduce to subsequent rapid drying as well as the control of energy consumption during drying by providing a device for squeezing and dehydrating refined cotton.

The connection point of the bottom end of the reflux tube 63 with the dehydrating box body 2 is positioned above the fixing frame 54 and below the material-supporting plate 56. The reflux tube 63 is configured to convey the sewage coming from the pre-dehydrating operation, so that the sewage coming from the pre-dehydrating operation and the sewage rising from the squeezing operation can be simultaneously filtered through the strainer 58.
The vibration mechanism 12 is arranged on the dehydrating box body 2, used to vibrate the sewage squeezed by the squeezing and dehydrating mechanism 11 and the sewage discharged from the reflux tube 63 during the operation of the pre-dehydrating mechanism 10. The vibration mechanism 12 includes the fourth rotation shaft 47 rotationally installed on the side of the dehydrating box body 2, the fourth cylindrical gear 48 fixedly installed on the outer surface of the fourth rotation shaft 47 and engaging with the third cylindrical gear 46, two fifth rotation shafts 49 rotationally installed on the dehydrating box body 2, and three belt pulleys respectively fixed on the outer surface of the fourth rotation shaft 47 and the outer surfaces of the two fifth rotation shafts 49. The three belt pulleys 50 are connected with each other through the belt 51 by ways of transmission, the cam 52 is fixed on the outer surface of the fifth rotation shaft 49, the outer surface of the cam 52 fits on the lower surface of the installation frame 57 of the strainer 58. The fourth cylindrical gear 48 engages with the third cylindrical gear 46 to enable the fourth rotation shaft 47 to rotate, and the fifth rotation shaft 49 to rotate under the transmission of the belt 51 and the belt pulley 50, and then the cam 52 to rotate. In this way, the installation frame 57 drives the strainer 58 to move up and down to enable the strainer 58 to vibrate up and down, avoiding the mesh holes of the strainer 58 from being blocked.
The drain pipe 14 is installed on and penetrates through the dehydrating box body 2 and a drain valve 71 is installed on the drain pipe 14.
During use, firstly feeding the refined cotton material to be treated into the pre-dehydration drum 4, then starting the twin-shaft motor 36, so that the twin-shaft motor 36 drives the first rotation shaft 25 to rotate under the action of the two bevel gears 35 engaging with each other, and the first rotation shaft 25 rotates to drive the first reciprocating screw 26 to rotate, thus the latter drives the moving plate 27 to move up and down, thereby driving the installation plate 28 to move up and down. When the installation plate 28 drives the third wedge-shaped plate 29 and the fourth wedge-shaped plate 30 to move downwards synchronously, the third wedge-shaped plate 29 cooperates with the first wedge-shaped plate 18, enabling two first wedge-shaped plates 18 to relatively move close to each other, so as to achieve the pre-dehydrating operation. When the installation plate 28 continues to move downwards, the third wedge-shaped plate 29 will separate from the first wedge-shaped plate 18, at this time the two pre-dehydrating plates 8 will return to their original positions, meanwhile the fourth wedge-shaped plate 30 will cooperate with the second wedge-shaped plate 23, driving two second wedge-shaped plates 23 to relatively move far away from each other, so as to achieve the laying-off operation, at this time the installation plate 28 has moved to the bottom. Then the installation plate 28 moves upwards, at this time the fourth wedge-shaped plate 30 separates from the second wedge-shaped plate 23, when the installation plate 28 continues to move upwards, the second arc-shaped surface cooperates with the first arc-shaped surface, so as to enable the third wedge-shaped plate 29 to move outwards to be misaligned with the first wedge-shaped plate 18, so that the first wedge-shaped plate 18 does not hinder the upward movement of the third wedge-shaped plate 29. The third wedge-shaped plate 29 moves upwards to the highest point, and then returns to its original position under the action of the third spring 33, so as to achieve the pre-dehydrating operation once. The sewage coming from the pre-dehydrating operation is conveyed to the upper part of the strainer 58 inside the dehydrating box body 2 via the reflux tube 63, and the material coming from laying-off baffle 9 falls on the upper part of the material-supporting plate 56. At the same time, the first cylindrical gear 37 and the third cylindrical gear 36 engage with each other, enabling the second rotation shaft 38 to drive the second reciprocating screw 39 to rotate, and then the latter enables the moving frame 40 to drive the squeezing and dehydrating roller 43 to move backwards and forwards. Cooperating and engaging with the second cylindrical gear 44 enables the squeezing and dehydrating roller 43 to rotate, simultaneously moving backwards and forwards, so as to achieve the highly-efficient squeezing and dehydrating operation of materials. The sewage coming from the squeezing operation also falls on the upper part of the strainer 58, then the strainer 58 filters and segregates the sewage, at the same time, the fourth cylindrical gear engages with the third cylindrical gear 46 to enable the fourth rotation shaft 47 to rotate, and the fifth rotation shaft 49 to rotate under the transmission of the belt 51 and the belt pulley 50, and then the cam 52 to rotate. In this way, the installation frame 57 drives the strainer 58 to move up and down to enable the strainer 58 to vibrate up and down, avoiding the mesh holes of the strainer 58 from being blocked. The cylinder 5 elongates to drive the dehydrating box cover 3 to move upwards at the time of taking materials after finishing the operation, so as to separate the dehydrating box cover 3 from the dehydrating box body 2, then just pulling the material-supporting mechanism 13 up enables taking materials.
