The invention discloses a water-cooling closed feeding screw conveyor which comprises a receiving hopper, an upper sealing valve, a replacement tank, a lower sealing valve, a storage tank, a discharging valve and a screw conveyor, a discharging port of the receiving hopper is connected with a feeding port of the replacement tank through the upper sealing valve, and a discharging port of the replacement tank is connected with a feeding port of the storage tank through the lower sealing valve. A discharging opening of the storage tank is connected with a feeding opening of the spiral conveyor through a discharging valve; a spiral blade shaft of the spiral conveyor is provided with a hollow inner cavity in the length direction, and the hollow inner cavity of the spiral blade shaft is filled with cooling water. The device is simple and reliable, can convey materials hermetically in a high-temperature environment, prevents high-temperature oxidation of the materials caused by entering air, and is particularly suitable for the industrial fields of smelting, calcining and the like.
Description
technical field [0001] The invention relates to the technical field of material conveying, in particular to a water-cooled sealed feeding screw conveyor. Background technique [0002] In the fields of industrial smelting and calcination, screw mechanisms are often used to transport raw materials. Due to the high temperature of the smelting or calcination furnace, the conveying mechanism often needs to meet the requirements of stable work in a high temperature environment, and, for some special materials, it should also prevent air from entering the high temperature furnace with the material, causing high temperature oxidation of the material and affecting product quality. [0003] Therefore, it is very meaningful to develop a feeding device with water cooling, which can work stably in a high temperature environment and can effectively avoid high temperature oxidation of raw materials. Contents of the invention [0004] The technical problem to be solved by the present inv...
