The invention provides a quartz sand pickling device. The quartz sand pickling device is capable of solving a problem in the prior art that quartz sand cannot be fully soaked and pickled. The quartz sand pickling device comprises a pickling tank and a hydrochloric acid pool; the pickling tank comprises a tank body, a top cover and a pickling assembly; the upper end of the tank body is provided with an opening, and an acid pickling chamber is formed inside the tank body; a liquid outlet and a sand outlet are formed in the side wall of the tank body; the pickling assembly comprises a sand washing plate, a pickling pipe and a liquid inlet pipe; the sand washing plate is obliquely mounted at the lower part of the acid pickling chamber; the liquid outlet is arranged on the lower part of the sand washing plate; a plurality of micropores are formed in the sand washing plate; the sand outlet is formed in the lower side of the upper end surface of the sand washing plate; sealing valves are installed on the outer sides of the liquid outlet and the sand outlet, the pickling pipe is laid on the sand washing plate and comprises a main pipe and a plurality of branch pipes, a liquid inlet is formed in the main pipe, the branch pipes are installed on the main pipe in a communicated mode, liquid outlet heads are installed on the branch pipes; one end of the liquid inlet pipe is communicated with the liquid inlet, and the other end of the liquid inlet pipe is communicated with the hydrochloric acid pool.
Description
technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a pickling device for quartz sand. Background technique [0002] In order to remove the iron powder and other impurities entrained in the powdery quartz sand and improve the purity of the quartz sand, it is often necessary to corrode the iron powder and other impurities in the powdery quartz sand with hydrochloric acid on the purification equipment for purification. This step is called pickling. Existing pickling devices generally use pickling tanks to fully soak the quartz sand in the solution with hydrochloric acid, and then discharge the quartz sand. In this process, hydrochloric acid is generally injected into the pickling tank in advance. After the quartz sand falls, the quartz sand at the bottom receives greater pressure, and some of the quartz sand cannot fully contact the hydrochloric acid, resulting in incomplete pickling, and the iron powder in the quartz san...
