[0003] In the above-mentioned prior art, when separating and purifying hexachloroethane for recovery, purification is often carried out by a method of evaporation followed by condensation. During the evaporation process, gas impurities are filtered through a fixed activated carbon layer. However, in this process, as the filtration process proceeds, the adsorption capacity of the activated carbon layer decreases, affecting the purification process, resulting in poor purification effect of hexachloroethane. Therefore, a separation and purification device for recovering hexachloroethane is proposed. Summary of the invention

[0004] In order to solve the problem that when separating and purifying hexachloroethane for recovery, purification is often performed by a method of evaporation followed by condensation, and gas impurities are filtered through a fixed activated carbon layer during the evaporation process, but in this process, as the filtering process proceeds, the adsorption capacity of the activated carbon layer decreases, affecting the purification process, resulting in a poor purification effect of hexachloroethane, the present invention provides a separation and purification device for recovering hexachloroethane.

[0005] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions: A separation and purification device for recovering hexachloroethane comprises a heating furnace, an evaporation port is installed on the heating furnace, a heating mechanism for evaporating hexachloroethane is installed on the heating furnace, a bend is installed on the evaporation port, a filter layer mechanism for an adjustable filter layer is installed on the bend, a riser is installed on the bend, a dome bottle is installed on the riser, a condensation mechanism for condensing and crystallizing hexachloroethane is installed on the dome bottle, a feeding mechanism for separating crystalline hexachloroethane is installed on the condensation mechanism, a transmission mechanism for driving the filter layer mechanism to move is installed on the feeding mechanism, a feeding mechanism for taking out crystalline hexachloroethane is installed on the feeding mechanism, and when separating and purifying hexachloroethane, hexachloroethane and impurity separation are separated by evaporating hexachloroethane through the heating mechanism according to different melting points. The gaseous hexachloroethane is further filtered through the filter layer mechanism. The filtered hexachloroethane is condensed and liquefied when it reaches the dome bottle through the riser. The liquefied hexachloroethane is crystallized and precipitated after passing through the condensation mechanism to obtain hexachloroethane crystals separated from impurities, thereby further improving the purification effect. In this process, the continuously crystallized hexachloroethane falls into the feeding mechanism, and the feeding mechanism drives the transmission mechanism to move. The movement of the transmission mechanism drives the filter layer mechanism to move, thereby improving the filtering effect of the filter layer mechanism, thereby further improving the purification effect of hexachloroethane. The weight in the feeding mechanism makes the crystallized hexachloroethane fall into the feeding mechanism when the parts of the feeding mechanism contact the feeding mechanism, which is convenient for further separation and removal, thereby improving the separation and purification effect of hexachloroethane.

[0006] Furthermore, the heating mechanism includes an inner liner, which is installed on the heating furnace. A coil is sleeved on the inner liner, and a temperature controller is electrically connected to the coil. The temperature controller is installed on the heating furnace. The coil is controlled by the temperature controller to achieve uniform heating of the inner liner, which facilitates the evaporation of hexachloroethane and improves the purification effect of hexachloroethane.

[0007] Furthermore, the filter layer mechanism includes a cavity disk, which is installed on the curved pipe. The cavity disk is connected to the curved pipe, and the inner diameter of the cavity disk is tangent to the inner diameter of the curved pipe. A limit swivel is rotatably installed on the cavity disk, and a rotating disk is installed on the limit swivel. An activated carbon disk is installed on the rotating disk, and the activated carbon disk is adapted to the curved pipe. When the limit swivel rotates, the rotating disk and the activated carbon disk on the rotating disk are driven to rotate, so that different parts of the activated carbon disk can filter hexachloroethane, thereby improving the filtering effect of the activated carbon disk, reducing the replacement frequency of the filter layer, and improving the convenience of using the equipment.

[0008] Furthermore, a sealing ring is installed on the rotating disk, and a sealing groove is opened on the cavity disk. The sealing ring is rotatably installed in the sealing groove. The sealing groove limits the movement of the sealing ring. The sealing ring can and can only rotate in the sealing groove, thereby improving the sealing performance of the equipment and further improving the practicability and safety of use of the equipment.

[0009] Furthermore, the condensation mechanism includes a threaded tube, which is installed on the bottom side of the dome bottle, a return pipe is sleeved on the threaded tube, a connecting pipe is installed on the return pipe, a condenser is installed on the connecting pipe, and the thread is located on one side of the cavity disk. When liquid hexachloroethane passes through the threaded tube, the flow rate slows down. In this process, the temperature is controlled at 186 degrees Celsius through the setting of the condenser, and hexachloroethane crystals are precipitated and fall through the threaded tube.

[0010] Furthermore, the feeding mechanism includes a conical top, which is mounted on the threaded tube, a feeding bin is mounted on the conical top, a connecting frame is mounted on the feeding bin, the connecting frame is mounted on the cavity disk, a sliding hole is opened on the feeding bin, a sliding rod is slidably mounted in the sliding hole, a filter inclined plate is mounted on the sliding rod, the filter inclined plate is slidably mounted on the feeding bin, a spring is movably sleeved on the sliding rod, one end of the spring is mounted on the filter inclined plate, and the other end of the spring is mounted on the feeding bin. When the crystallized hexachloroethane enters the feeding bin, it falls on the filter inclined plate. As the amount of crystallized hexachloroethane increases, the weight of the filter inclined plate increases and squeezes the sliding rod, and the sliding rod slides on the feeding bin and squeezes the spring.

[0011] Furthermore, the transmission mechanism includes a connecting rotating plate, a rotating shaft is installed on the connecting rotating plate, a rotating hole is opened on the sliding rod, the rotating shaft is rotatably installed in the rotating hole, a rotating seat is rotatably installed on the connecting rotating plate, a transmission column is installed on the rotating seat, the transmission column is slidably installed in the limiting rotating ring, a limiting round block is installed on the transmission column, and the limiting round block is located on one side of the cavity disk. During the sliding process of the sliding rod, the connecting rotating plate is driven to move, and the connecting rotating plate rotates on the rotating seat and the sliding rod, thereby driving the rotating seat and the transmission column to slide on the limiting rotating ring to realize the transmission function.

[0012] Furthermore, a transmission shaft block is installed on the transmission column, an elliptical groove is opened on the limiting swivel, and the transmission shaft block is slidably installed in the elliptical groove. During the sliding process of the transmission column, the transmission shaft block is driven to slide in the elliptical groove, thereby driving the limiting swivel to rotate on the cavity disk.

[0013] Furthermore, the feeding mechanism includes a feeding chamber, which is installed on the lower feeding bin, a filter tank is installed on the feeding chamber, a movable valve is installed on the filter tank, a filter plate is installed in the feeding chamber, and a movable plate is movably installed on the feeding chamber. When the filter inclined plate moves to be connected with the feeding chamber, crystallized hexachloroethane falls into the feeding chamber for collection, and the structure is reset under the action of the restoring elastic force of the spring, which is convenient for re-transmission. When the crystallized hexachloroethane needs to be taken out, the impurity liquid is removed by opening the movable valve, and then the movable plate is opened to take it out.

[0014] The beneficial effects of the present invention are as follows: The present invention, through the arrangement of the cavity disk, the rotating disk, the filtering inclined plate, the sliding rod and the like, realizes that in the process of hexachloroethane purification, the weight of the crystalline hexachloroethane continuously precipitated during purification drives the cavity disk to rotate, thereby driving the activated carbon layer to continuously rotate during the filtering process to contact the hexachloroethane-containing impurity gas through different parts of the activated carbon layer, thereby improving the adsorption capacity of the activated carbon layer, improving the hexachloroethane purification effect, reducing the replacement frequency of the activated carbon layer, and improving the practicality and convenience of use of the equipment.

[0015] The present invention realizes uniform heating of the inner lining by arranging the coil and the temperature controller, thereby facilitating the evaporation of hexachloroethane and improving the purification effect of hexachloroethane.

[0016] The present invention improves the sealing performance of the equipment by arranging the sealing ring, the sealing groove and the like, and further improves the practicability and safety of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS
