Abstract

The invention discloses a feeding system for powdery materials, belongs to the field of material conveying equipment, and aims to solve the problems that in the prior art, a screw feeder is easy to corrode by a molten salt chlorination furnace, and the screw feeder and the chlorination furnace are easy to block. The feeding system comprises a chlorination furnace, a screw cylinder and a spiral conveying rod, wherein the screw cylinder is connected with the chlorination furnace, one end of the spiral conveying rod is arranged in the screw cylinder, the other end of the spiral conveying rod is far away from the chlorination furnace and penetrates out of the screw cylinder, the part, penetrating out of the screw cylinder, of the spiral conveying rod is connected with a push plate through a bearing, and a hydraulic cylinder is arranged on the push plate. According to the invention, the hydraulic cylinder provides radial force for the spiral conveying rod, so that the spiral conveying rod pushes accumulated materials and formed hardened materials into the chlorination furnace together, and the blockage problem of the spiral feeding machine is effectively avoided; and the accumulated materials can be used as a buffer layer to play a role in sealing, so that molten salt and high-temperature corrosive gas in the chlorination furnace are prevented from entering the spiral conveying rodto corrode the spiral conveying rod.

Description

Technical field [0001] The invention belongs to the field of material conveying equipment, and specifically belongs to a feeding system for powdery materials. Background technique [0002] Molten salt chlorination furnace is a high-efficiency chlorination equipment that uses titanium-rich materials in the presence of carbon to produce titanium tetrachloride through chlorine chlorination. There are two ways to feed molten salt chlorination furnace: One is to feed from the top of the molten salt chlorination furnace, mostly for emergency feeding, the second is to feed from the molten salt chlorination furnace near the top of the molten salt, and currently the second method of feeding is more commonly used. [0003] The feeding method from above the molten salt liquid level is to convey the mixed material directly to the chlorination furnace through a screw feeder, which can effectively transport the fine particles in the material to the molten salt chlorination furnace, but the chlor...
