Embodiment Construction

[0018] figure 1 and figure 2 The basic structure of the preferred embodiment of the present invention is shown. The silicon material pickling integrated tank includes a main tank 1, a secondary tank 6 and a tank cover (not shown) connected to an external exhaust system. The main tank 1 is connected to the upper part of the cavity of the auxiliary tank 6 to form an integrated tank body of the main tank and the auxiliary tank. There is a gap between the outer wall of the main tank 1 and the inner wall of the auxiliary tank 6. The upper edge of the main tank is provided with a wavy overflow port 2 (or a rectangular overflow port), and the lower part of the inner cavity of the main tank 1 is provided with a support Block 3. A cooling system that can cool the liquid medicine in the main tank 1 is also communicated between the main tank and the auxiliary tank. In this embodiment, the cooling system includes: an infusion tube 7 arranged at the bottom of the main tank 1, a liquid ...

Abstract

The invention discloses a connected groove of a silicon material acid plant. The connected groove comprises a primary groove (1), a secondary groove (6) and a groove cover, wherein the primary groove (1) is arranged on the upper part in a cavity of the secondary groove (6) to form an integrated groove body of the primary groove and the secondary groove; a clearance is kept between an outer wall of the primary groove (1) and an inner wall of the secondary groove (6); an overflow port is arranged on the upper part edge of the primary groove; and a cooling system is communicated between the primary groove and the secondary groove and can be used for cooling the liquid in the primary groove (1). The secondary groove and the primary groove are connected to be integral, the functional completeness can be ensured, while the parts in the circulation process are reduced, leakage danger of chemicals is reduced; the stability and safety of the groove acid plant are enhanced due to the integrity; and the production efficiency is improved, and the cost is reduced.

Description

technical field [0001] The invention relates to chemical treatment equipment for materials such as polycrystalline silicon materials, silicon cores, and battery sheets, and in particular to a pickling connected tank for materials such as silicon materials and silicon cores. Background technique [0002] In polysilicon material pickling equipment, it is necessary to ensure the stability of the acid circulation process and the safety of equipment use, which will directly affect the quality, efficiency and safety of production. [0003] At present, the existing pickling tank is mainly connected through the main tank and an external auxiliary tank. In the production process, due to the certain distance between the main tank and the auxiliary tank, there is a problem that the connecting pipe is too long when realizing the acid liquid circulation between the main tank and the auxiliary tank, so that excessive heat transfer is caused during the circulation process , so that the te...
