Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of distillation columns, in particular to a methyltrichlorosilane distillation column. Background Art
[0002] A distillation column is a tower-type gas-liquid contact device for distillation. By utilizing the property that each component in the mixture has different volatilities, that is, the vapor pressures of each component are different at the same temperature, the light components (low-boiling substances) in the liquid phase are transferred to the gas phase, while the heavy components (high-boiling substances) in the gas phase are transferred to the liquid phase, thereby achieving the purpose of separation.
[0003] When the existing distillation column discharges materials, the filter plate at the bottom of the distillation column is prone to blockage, which is rather troublesome to dredge and not easy to clean, affecting the production efficiency. Content of the Utility Model
[0004] The main purpose of the utility model is to provide a methyltrichlorosilane distillation column to solve the problems mentioned in the background art.
[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0006] A methyltrichlorosilane distillation column includes a distillation column body. A discharge pipe is connected to the lower end of the distillation column body. A first valve is provided on the discharge pipe. A filter plate is provided in the discharge pipe, and the filter plate is provided with a number of vertical filter holes. An anti-blocking component for dredging the filter plate is provided in the discharge pipe. The anti-blocking component includes a cylinder, a movable rod, a stainless steel wire, a fixed rod, and a vibration motor. The cylinder is horizontally fixed on one side of the discharge pipe and is located above the filter plate. The telescopic rod of the cylinder movably passes through the discharge pipe and is connected to a horizontal movable rod. A fixed rod is provided in the discharge pipe below the filter plate. A number of tensioned stainless steel wires are connected between the movable rod and the fixed rod, and one stainless steel wire passes through each filter hole. A vibration motor is provided at the center of the bottom of the fixed rod.
[0007] Further, a clear water pipe is connected to the discharge pipe. The clear water pipe is located below the fixed rod, and a second valve is provided on the clear water pipe.
[0008] Further, a sewage discharge pipe is connected to the distillation column body beside the discharge pipe, and a third valve is provided on the sewage discharge pipe.
[0009] The utility model further includes other components that can enable the normal use of the methyltrichlorosilane distillation column, and these devices or components all adopt conventional technical means in the art. In addition, the devices and components not defined in the utility model all adopt conventional technical means in the art, such as the first valve and the vibration motor in this application. In the specific implementation process, appropriate device or component models can be selected according to the specific working scenario.
[0010] The working principle of the present utility model is as follows: When discharging materials, since the stainless steel wire is elastic, the air cylinder can drive the movable rod to move back and forth slightly left and right in the discharge pipe. At the same time, the vibration motor installed on the fixed rod vibrates continuously, causing the stainless steel wire to vibrate continuously in the filter holes, thus preventing the material from blocking the filter holes. When cleaning the filter plate, close the first valve, open the second valve and the third valve, inject clear water into the discharge pipe from the clear water pipe, and at the same time keep the anti-blocking component in the working state. The clear water flushes the filter plate from bottom to top, and the dirt washed down is discharged from the sewage pipe.
[0011] Compared with the prior art, the present utility model has the following beneficial effects: It can prevent the filter plate at the bottom of the rectification tower discharge pipe from being blocked, and the filter plate is easy to clean, improving the production efficiency.

An anti-blocking component for dredging the filter plate 5 is provided in the discharge pipe 2. The anti-blocking component includes an air cylinder 3, a movable rod 4, a stainless steel wire 6, a fixed rod 7, and a vibration motor 8. The air cylinder 3 is horizontally fixed on one side of the discharge pipe 2 and is located above the filter plate 5. The telescopic rod of the air cylinder 3 movably passes through the discharge pipe 2 and is connected to a horizontal movable rod 4. A fixed rod 7 is provided in the discharge pipe 2 below the filter plate 5. A plurality of tensioned stainless steel wires 6 are connected between the movable rod 4 and the fixed rod 7. One stainless steel wire 6 passes through each filter hole 13. A vibration motor 8 is provided in the middle at the bottom of the fixed rod 7.
