Description

Technical Field

[0001] This utility model relates to the field of automated machinery, and in particular to a lifting scraper device for silicon powder condensation. Background Technology

[0002] To achieve the production of high-purity silicon, a process was proposed that involves vaporizing molten silicon with a laser and then condensing it using a condensation device. To improve production efficiency, multiple straight-rod-type condensation units were designed. However, during the silicon powder condensation process, some silicon powder condenses and adheres to the condensation unit. Over time, this accumulation of silicon powder forms a silicon powder layer. As time progresses, the thickness of this layer continuously increases, affecting the condensation efficiency of the condensation unit and making it impossible to collect the adhered silicon powder. Utility Model Content

[0003] The main purpose of this invention is to provide a lifting scraper device for silicon powder condensation.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A lifting and scraping device for silicon powder condensation includes a lifting frame, a lifting cylinder, lifting guide rods, a first lifting guide sleeve, a second lifting guide sleeve, and a scraper. The lifting cylinder is fixedly installed on the lifting frame. The output end of the lifting cylinder passes through the lifting frame and is fixedly connected to the lifting guide rod. The first lifting guide sleeves are symmetrically fixedly installed on the lifting frames on both sides of the lifting cylinder. The first lifting guide sleeves are also slidably connected to the lifting guide rods. A second lifting guide sleeve is slidably fitted on each of the three lifting guide rods. The scraper is fixedly connected to the three lifting guide rods through the second lifting guide sleeves.

[0006] Furthermore, sealing rings are fixedly installed at both the upper and lower ends of the second lifting guide sleeve.

[0007] Furthermore, the output end of the lifting cylinder is connected to the lifting guide rod via a floating connector.

[0008] Furthermore, the scraper plate includes a connecting plate and a scraper blade. The connecting plate is fixedly provided with a plurality of scraping holes, and the scraper blade is fixedly installed on the inner wall of the scraping holes.

[0009] Furthermore, the scraper includes a first scraper and a second scraper. The first scraper and the second scraper have the same structure, both being semi-circular arc-shaped scrapers. The first scraper and the second scraper form a complete circular ring structure.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This invention achieves a seal between the device and the condensation equipment through a second lifting guide sleeve. The power component is placed outside the equipment, allowing the scraper to be placed inside the equipment, thus removing silicon powder from the condensation equipment. A better scraping effect is achieved through a special scraper. Attached Figure Description
