The downward movement of the movable plate will drive the long rod to move downward, and the downward movement of the long rod will drive multiple fan plates to move downward. When the rotation of the cricket block does not conflict with the arc surface of the vertical column, the spring will reset by its own elastic force, and the reset of the spring will drive the movable plate to reset. The reset of the movable plate drives the vertical column, the long rod, and multiple fan plates to reset, and so on, thereby causing the multiple fan plates to reciprocate up and down.

Pour the acetone to be purified into the distillation kettle through the liquid inlet pipe, then fix the distillation kettle with an external bracket, and then heat the fixed distillation kettle in a water bath.

[0014] The present invention provides a 2-chloro-1-(1-chlorocyclopropyl)ethanone purification device and processing technology. It has the following beneficial effects: (1) The present invention cooperates with the vertical rod, the support ring, the fixed plate, the first rotor, the second rotor, the belt, the rotating rod, the fan blades, and the guide round block so that the rotation of the fan blades will extract the vapor of acetone into the conduit, thereby avoiding that during the evaporation of acetone, most of the evaporated gas will be located at the top of the distillation kettle, and a small part will flow through the conduit to the external condenser. Therefore, the liquid converted from gas at the top of the distillation kettle needs to be re-evaporated, thereby reducing the purification speed of acetone.

When the multiple fan plates move upward, the steam will float to the bottom of the lowest fan plate. When the multiple fan plates move downward, the steam under the lowest fan plate will float to the conical groove of the guide block, so that the fan blades can increase the steam extraction speed and reduce the steam adhesion to the bottom of the inclined surface of the guide block, thereby increasing the purification speed of acetone; at the same time, through the cooperation of the fan plates and the long rod, the multiple fan plates can drop the water droplets at the bottom of the lowest fan plate into the distillation kettle faster while reciprocating, thereby ensuring the purification efficiency of acetone.

The reciprocating movement of the thorn ball will break the bubbles generated in the process of acetone purification, thereby reducing the situation where the existence of bubbles will reduce the heat conduction efficiency of acetone.

Therefore, the liquid converted from gas at the top of the distillation kettle 1 needs to be re-evaporated, thereby reducing the purification speed of acetone. At the same time, the inclined surface at the bottom of the guide round block 79 will guide the gas to the conduit 3, thereby increasing the speed at which the gas enters the conduit 3.

Through the arrangement of the above structure, the resetting of the movable plate 83 drives the vertical column 87, the long rod 85, and the multiple fan plates 86 to reset, and so on, so that the multiple fan plates 86 reciprocate up and down. When the multiple fan plates 86 move upward, the steam will float to the bottom of the lowest fan plate 86. When the multiple fan plates 86 move downward, the steam under the lowest fan plate 86 will float to the conical groove of the guide round block 79, so that the fan blades 78 can increase the extraction speed of the steam, and can reduce the adhesion of the steam to the bottom of the inclined surface of the guide round block 79, thereby increasing the purification speed of acetone.

[0023] During use, the acetone to be purified is poured into the distillation kettle 1 through the liquid inlet pipe 2, and the distillation kettle 1 is then fixed by an external bracket. The fixed distillation kettle 1 is then heated in a water bath. The acetone is converted into water vapor by heating and flows into the external condenser through the conduit 3. Finally, the water vapor is condensed into water droplets by the condenser for collection. When the acetone is heated, the staff starts the motor 5, and the output shaft of the motor 5 rotates the shaft 6. The rotation of the shaft 6 drives the stirring blade 10 to rotate. The rotation of the stirring blade 10 stirs the acetone. The rotation of the shaft 6 also drives the runner 2 75 to rotate. The rotation of the runner 2 75 drives the runner 1 74 to rotate through the belt 76. The rotation of the runner 1 74 drives the rotating rod 77 to rotate. The rotating rod 7 The rotation of 7 drives the fan blades 78 to rotate, and the rotation of the fan blades 78 will extract the acetone vapor into the conduit 3, thereby avoiding that during the evaporation of acetone, most of the evaporated gas will be located at the top of the distillation kettle 1, and a small part will flow into the external condenser through the conduit 3. Therefore, the liquid converted from gas at the top of the distillation kettle 1 needs to be re-evaporated, thereby reducing the purification speed of acetone. At the same time, the inclined surface at the bottom of the guide round block 79 will guide the gas to the conduit 3, thereby increasing the speed of the gas entering the conduit 3; before the gas is extracted by the fan blades 78 and enters the conduit 3, the spiral grooves 711 on the surface of the conical block 710 will cause the gas to float in a spiral shape, and the spiral floating of the gas will correspond to the shape of the gas extracted by the fan blades 78, thereby further improving the efficiency of the fan blades 78 in extracting the gas.

The bottom of the fixed ring 95 is fixedly connected to multiple support rods 96, and the bottoms of the multiple support rods 96 are fixedly connected to a number of thorn balls 97. Through the arrangement of the above structure, the reciprocating motion of the fixed ring 95 drives the support rods 96 to move back and forth, and the reciprocating motion of the support rods 96 drives the thorn balls 97 to move back and forth. The reciprocating motion of the thorn balls 97 will break the bubbles generated during the purification process of acetone, thereby reducing the situation where the presence of bubbles will reduce the heat conduction efficiency of acetone.
