Silicon material cleaning device

Abstract

The present invention relates to a silicon material cleaning device, which belongs to the technical field of cleaning devices of material used in electronic and electric parts. The silicon material cleaning device comprises a pickling bath, the upside of which is equipped with a movable cover, and one side near the bottom of the pickling bath is provided with a drainpipe. A material containing roller is arranged in the pickling bath and is provided with a material door. A material containing roller driving mechanism is connected with the material containing roller. A high pickling solution storage vat is arranged above the pickling bath and is communicated with the pickling bath. A low pickling solution storage vat is arranged at one side of the pickling bath and is communicated with the pickling bath. A pickling solution lifting mechanism is communicated with the high pickling solution storage vat and the low pickling solution storage vat. A water inlet pipeline is connected with the upper part of the pickling bath and extends into the pickling bath. An air exchanging mechanism is communicated and connected with the pickling bath in a circular way. Harmful gas can not cause influence on operating workers. The silicon material cleaning device has low labor intensity and high pickling efficiency, so that the exhaust gas in the pickling bath can be replaced before the movable cover is opened, and the exhaust gas produced during the pickling process can be introduced to an exhaust gas treatment device to be disposed.

Description

technical field [0001] The invention belongs to the technical field of cleaning devices for materials used in electronic and electrical components, and in particular relates to a silicon material cleaning device. Background technique [0002] At present, an open pickling tank is usually used for surface cleaning of silicon materials. The silicon material block or a container containing the silicon material block, such as a basket, is manually put into the pickling tank, and the silicon material block is frequently stirred manually. Because in the whole pickling process, a large amount of hydrogen fluoride (HF) and nitrogen dioxide (NO2) will be produced 2 ) and other harmful gases. Therefore, a suction hood is used for exhausting. The suction hood generally corresponds to the top of the opening of the pickling tank. The aforementioned harmful gases sucked by the suction hood are introduced into the exhaust gas treatment device for treatment. [0003] The above-mentioned dis...

Problems solved by technology

[0003] The above-mentioned disposal method has the following shortcomings: first, because it is an open pickling, HF and NO 2 Such harmful gases cannot be completely sucked by the suction hood, and some of them are dispersed in the air at the job site, which poses a hazard to the health of workers working on-line and affects the protection of the environment; secondly, in order to make the suction hood as clean as possible Harmful gases are absorbed in many places, so the exhaust volume of the suction hood is relatively large, which increases the difficulty and cost of the subsequent exhaust gas treatment device
