[0003] However, the secondary feeding barrel in the current CZ single crystal pulling process is made of quartz material, and different sizes are distinguished according to the weight of the feeding. Before feeding, the feeding amount is calculated based on the weight of the remaining material in the furnace, and the feeding is added multiple times according to the proportion. When the feeding is disconnected, the weight of a single feeding is far less than the current feeder specifications, which wastes the feeder and process time. Utility Model Content

[0004] The purpose of the present utility model is to provide a segmented feeder to solve the problem in the above-mentioned background technology that the weight of the feed is distinguished by different specifications, the feed amount is calculated according to the weight of the remaining material in the furnace before feeding, and the feed is added multiple times according to the proportion. When the feed line is disconnected, the weight of the single feed is far less than the current feeder specifications, which wastes the feeder and process time.

[0005] To achieve the above-mentioned purpose, the present utility model provides the following technical solutions: a segmented feeder, comprising a lower bin and a connecting rod;

[0006] A quartz cone A is provided at the bottom end of the connecting rod on the inner wall of the lower hopper;

[0007] An upper bin is provided at the upper end of the lower bin;

[0008] The lower silo and the upper silo are fixedly connected by threads, and a quartz cone B is provided on the upper side of the outer wall of the connecting rod, and the quartz cone B is used to block the lower side of the upper silo.

[0009] Preferably, the connection between the lower hopper and the upper hopper is widened, and the quartz cone B can be driven to move up and down by a connecting rod.

[0010] Preferably, a fixing ring is sleeved on the upper side of the outer wall of the connecting rod, and a scraping ring is provided on the outer wall of the fixing ring. The fixing ring drives the scraping ring to move downward to scrape off attachments on the inner wall of the upper hopper.

[0011] Preferably, a collar is provided between the fixing rings, a through hole is provided in the middle of the collar, and the fixing ring is sleeved on the outer wall of the connecting rod through the through hole in the middle of the collar.

[0012] Preferably, the fixing ring and the sleeve ring are connected and fixed by a plurality of connecting rods, and counterweight blocks are provided in the gaps between the plurality of connecting rods and the inner wall of the fixing ring, and the plurality of counterweight blocks are used to increase the downward pressure of the fixing ring.

[0013] Preferably, a limiting ring is provided on the upper side of the outer wall of the lower hopper, and the limiting ring is used to support the lower hopper and fix it in the auxiliary chamber. An upper cover is provided on the upper end of the upper hopper, and the upper cover is used to prevent foreign matter from falling into the upper hopper.

[0014] Preferably, a connecting block is provided at the upper end of the connecting rod, a hanging hole is provided at the front end of the connecting block, and the hanging hole at the front end of the connecting block is used to connect with the lifting equipment in the auxiliary chamber.

[0015] Compared with the prior art, the present invention provides a segmented feeder with the following beneficial effects:

[0016] 1. After the lower hopper is filled with materials, the upper hopper is screwed and fixed to the upper end of the lower hopper, and a quartz cone B is provided on the upper side of the outer wall of the connecting rod. The upper hopper is blocked by the quartz cone B, and the materials are poured into the upper end of the upper hopper. The upper cover is sleeved on the outer wall of the connecting rod and fixed to the upper end of the upper hopper. The upper hopper and the lower material yard are fixed by the lifting rod and the connecting block. The upper hopper and the lower material yard are hoisted into the auxiliary chamber. When the material needs to be replenished, the lifting rod device in the auxiliary chamber drives the connecting rod to continue to descend, and the quartz cone A gradually separates from the discharge port of the lower hopper. The silicon material gradually flows out along the slope of the quartz cone A and falls into the quartz crucible below. When secondary feeding is needed, it is only necessary to continue to drive the connecting rod to continue to descend through the inner lifting rod device, so that the quartz cone B reaches the widened connection between the upper hopper and the lower hopper. The silicon material will fall down from the widened gap between the upper hopper and the lower hopper for secondary feeding, which can save the time and manpower of hanging materials and the labor time of secondary feeding.

[0017] 2. The silicon materials filled in the upper and lower silos are generally ground into fine particles first, so that they are easy to align in the quartz crucible for heating and melting. However, the dust in the fine silicon materials will adhere to the inner wall of the upper silo, resulting in the inability to completely discharge the materials in the upper silo during discharge, and it is also not convenient for subsequent cleaning. When the upper silo is filled with materials, the fixing ring is fixed to the outer wall of the connecting rod through the hole in the middle of the ring. While discharging the materials, the fixing ring will be driven by the weight of the counterweight to slide downward, and the materials attached to the inner wall of the upper silo will be scraped off by the scraper ring on the outer wall of the fixing ring, thereby avoiding some residues attached to the inner wall of the upper silo after the materials are discharged, and reducing the difficulty of subsequent cleaning.
