Description

Technical Field

[0001] The utility model relates to the technical field of dichlorosilane distillation and purification, and more specifically, to a dichlorosilane distillation and purification device. Background Art

[0002] In the existing technology, the dichlorosilane distillation and purification device is an important device for purifying dichlorosilane in chemical production. This device separates and purifies dichlorosilane through a multi-stage distillation process in a distillation tower. However, due to the differences in the composition of components at different positions in the distillation tower, the existing equipment is often unable to conveniently sample at various positions, which to some extent affects the convenience of the equipment and the flexibility of operation.

[0003] During the dichlorosilane distillation and purification process, the composition of components at different positions in the distillation tower is constantly changing. This change is due to the continuous separation and reorganization of light components and heavy components in the tower during the distillation process, resulting in significant differences in the composition of components at different heights in the tower. In order to ensure the purification effect and product quality, sampling and analysis are required at different positions so that the operating parameters can be adjusted in time. However, existing dichlorosilane distillation and purification devices often lack a convenient sampling system, which makes the operator face certain difficulties when sampling. This not only increases the labor intensity of the operator, but may also affect the accuracy and timeliness of the sampling results, thereby affecting the efficiency of the entire purification process and product quality.

[0030] In this embodiment, when a small amount of dichlorosilane in the distillation tower 1 needs to be sampled, first press on the middle rod 6, and then push the sealing block 7 to fit the lower end of the internal groove 9. At this time, the outlet 10, the through hole 8 and the internal groove 9 are interconnected, so a small amount of sampling can be performed.

When a large amount of sampling is needed, by pressing on the push rod 4, the spring 14 is compressed downward, and then the seal between the one-way disk 11 and the fitting ring 12 is released, and then the sampling process can be carried out. When the sealing effect between the one-way disk 11 and the fitting ring 12 needs to be adjusted, by rotating the push rod 4, the threaded sleeve 13 can be rotated along the sampling tube 2 under the action of the guide bar 15, so that the compression of the spring 14 can be changed, thereby adjusting the sealing effect between the one-way disk 11 and the fitting ring 12.
