Embodiment Construction
[0016] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.
[0017] Such as Figure 1 to Figure 8 As shown, a timing and quantitative mixing device for trichlorosilane production process includes a bracket 3 and a tank body 1 arranged at the upper end of the bracket 3. The tank body 1 is provided with a hydrolysis chamber, and a fixing member is fixed at the upper left end of the hydrolysis chamber. The left and right ends of the tank body 1 are respectively provided with a thick slag slurry inlet pipe 4 and a circulating water inlet pipe 5 communicating with the hydrolysis chamber. The lower end of the tank body 1 is provided with a slag material outlet pipe 6 and a circulating water outlet pipe communicating with the hydrolysis chamber. 7. The upper end...

The invention discloses a timing timed quantitative mixing and stirring device for a trichlorosilane production process. The timing timed quantitative mixing and stirring device comprises brackets anda tank body arranged at the upper ends of the brackets, wherein the tank body is internally provided with a hydrolysis cavity. A fixing member is fixed to the upper left end of the hydrolysis cavity,and a concentrated slurry inlet pipe and a circulating water inlet pipe which are in communication with the hydrolysis cavity are separately arranged at the left and right ends of the tank body. A slag charge outlet pipe and a circulating water outlet pipe which are in communication with the hydrolysis cavity are arranged at the lower end of the tank body, and an exhaust gas outlet pipe which isin communication with the hydrolysis cavity is arranged at the upper end of the tank body. A motor is arranged at the top end of the tank body, and an output shaft of the motor is connected with a stirring shaft penetrating through the fixing member to extend into the hydrolysis cavity. The timing timed quantitative mixing and stirring device has the advantages that in the trichlorosilane production process, alkaline liquid can be injected into the hydrolysis cavity in a timing timed and quantitative mode, and concentrated slurry can be fully hydrolyzed without wasting the alkaline liquid.
Description
Technical field [0001] The invention relates to a stirring device, in particular to a stirring device for mixing in a regular and quantitative manner in a trichlorosilane production process. Background technique [0002] In the production process of trichlorosilane, it is necessary to inject the thick slag slurry into the hydrolysis tank, then open the lye inlet pipe, put in 20-30% sodium hydroxide lye, so that the materials are hydrolyzed, and the qualified materials after the hydrolysis pass through the slag The discharge pipe is discharged to the silicon powder slag pool. However, it is impossible to mix the lye regularly and quantitatively, thereby causing waste to the lye or incomplete hydrolysis of the thick slurry. [0003] Therefore, there is a need for a trichlorosilane production process to be mixed into the stirring device regularly and quantitatively. In the trichlorosilane production process, the lye can be injected into the hydrolysis chamber regularly and quantitati...
