Description

Technical Field

[0001] The utility model relates to the technical field of germanium tetrachloride purification process, is suitable for the rectification and purification of germanium tetrachloride, and specifically relates to a flow direction control device for improving the germanium tetrachloride distillation reflux control system. Background Art

[0002] In the germanium tetrachloride distillation system, it is necessary to operate the germanium tetrachloride distillation liquid for reflux. In the prior art, an electromagnet is used to attract a valve body with a flow control body to achieve reflux drive. However, when the electromagnet has a large magnetic leakage, the electromagnet coil is prone to heat up, and long-term operation is prone to aging and damage of the insulation layer, which in turn leads to a short circuit and burnout of the coil. Utility Model Content

[0003] In order to avoid the above situation, the utility model

[0004] A control device for a germanium tetrachloride distillation reflux valve body, fixed on the front side of a reflux valve body with a flow control body and a guide tube, characterized in that: it comprises a horizontal bottom plate, vertical fixing rods and support rods are respectively fixed on both sides of the bottom plate, the fixing rod is longer than the support rod, a wire drum is arranged on the top of the support rod, the wire drum is driven to rotate by a DC motor, and a polytetrafluoroethylene traction belt is wound inside the wire drum; spring hanging holes of different heights are arranged at the part of the fixing rod higher than the support rod; two symmetrical bearings are arranged at the connection between the fixing rod and the bottom plate, the two bearings are connected to one end of a cantilever arm together, a hanging ring is arranged on the side of the cantilever arm close to the bearing, and the hanging ring is connected to any spring hanging hole through a spring; a hanging ring is also arranged at the other end of the cantilever arm, and one end of the polytetrafluoroethylene traction belt is tied to the hanging ring, and a permanent magnet is fixed in the middle of the cantilever arm.

[0005] Furthermore, a first positioning rod and a second positioning rod are fixed to the support rod, the first positioning rod and the cantilever arm in a horizontal state are located on the same plane, and the second positioning rod is located at the top of the cantilever arm when the permanent magnet is located directly in front of the flow control body.

[0006] Furthermore, the number of the spring hanging rings is three.

[0007] The beneficial effects of the utility model are: permanent magnets are used to replace electromagnets, and the permanent magnets are pulled by the traction belt and the cantilever arm, and the spring also pulls the cantilever beam at the same time, so that the cantilever beam is in a state of nearly equilibrium, so that the required traction force is reduced, the output power required by the DC motor to drive the wire drum is reduced, the input power required by the DC motor is reduced, the current during stalling is reduced, the heat is reduced, the coil is not easily burned, the DC motor can be stalled for a long time without burning, and the smaller the magnetic force of the coil inside the DC motor, the less likely it is to demagnetize the permanent magnet inside the DC motor, so that the system becomes reliable.

[0012] Embodiment 1: A control device for a germanium tetrachloride distillation reflux valve body, fixed on the front side of a reflux valve body 13 with a flow control body 14 and a guide tube 15, the device comprises a horizontal base plate 1, a vertical fixed rod 2 and a support rod 3 are fixed on both sides of the base plate 1, the fixed rod 2 is longer than the support rod 3, a wire drum 4 is arranged on the top of the support rod 3, the wire drum 4 is driven to rotate by a DC motor, and a polytetrafluoroethylene traction belt 5 is wound inside the wire drum 4; spring hanging holes 7 of different heights are arranged at the part of the fixed rod 2 higher than the support rod 3; two symmetrical bearings 6 are arranged at the connection between the fixed rod 2 and the base plate 1, the two bearings 6 are connected together to one end of a cantilever arm 9, a hanging ring is arranged on the side of the cantilever arm 9 close to the bearing, and the hanging ring is connected to any spring hanging hole 7 through a spring 8; a hanging ring is also arranged at the other end of the cantilever arm 9, and one end of the polytetrafluoroethylene traction belt 5 is tied to the hanging ring, and a permanent magnet 10 is fixed in the middle of the cantilever arm 9.

[0013] When the product needs to be taken, the DC motor is powered, the wire drum 4 drives the PTFE traction belt 5 to shrink, pulls the cantilever arm 9 to rotate from the position of the first limit rod 11 to the position of the second limit rod 12, and the flow control body 14 inside the valve body 13 changes the flow direction under the attraction of the permanent magnet 10, and then the product flows out through the guide pipe. Keep for a period of time, this process takes time t1.

[0014] When the product is taken out and a rest is needed, the DC motor stops supplying power, and the cantilever arm 9 falls down due to its own gravity. The cantilever arm 9 falls back to the first limit rod 11, and the flow control body 14 inside the valve body 13 changes the flow direction due to the attraction and traction of the permanent magnet 10 on the cantilever arm 9, and stops flowing out of the product without passing through the guide tube. Rest for a period of time, and this process takes time t2.
