Description

Technical Field

[0001] The utility model relates to the field of metallurgy, in particular to a alkali liquid tank feeding funnel. Background Art

[0002] Under the background of ultra-low emissions, the implementation of source control for blast furnace and coke oven gas fine desulfurization can not only reduce the sulfur content in the fuel gas, but also greatly reduce the pressure of end-of-pipe treatment. It is currently the most economical and convenient technical means for steel mills to implement. According to the characteristics of blast furnace gas, the hydrolysis conversion method or microcrystalline adsorption method is currently mainly used to achieve the conversion and removal of carbonyl sulfide. In the blast furnace gas fine desulfurization process, the organic sulfur in the gas is hydrolyzed into H2S by a hydrolyzing agent, and then the H2S is removed by wet alkali solution washing or dry activated carbon adsorption, absorbent absorption and metal oxide method, thereby achieving the purpose of blast furnace gas fine desulfurization. Alkali solution is indispensable in both wet and dry processes.

[0003] The existing Chinese patent application CN210996484U discloses a metallurgical powder feeding device. The patent solves the problem that the existing metallurgical powder feeding device generates a large amount of waste and particles during use, which brings great harm to people's health and pollutes the environment through the coordination between a fan, a suction pipe, a water tank, a threaded pipe, a top cover, a handle, a rubber pad and a water pipe.

[0004] However, in the current blast furnace gas desulfurization process in the industry, alkali is mainly added by manual handling, bag breaking, and feeding into a funnel. The alkali bag is generally about 50kg, which can easily lead to high labor intensity for workers. Dust is easily generated during the alkali addition process, which can also affect the health of workers. In addition, the addition of flake alkali to the bucket elevator is prone to blockage, affecting the feeding efficiency. For this reason, it is necessary to provide a funnel device that can assist in alkali addition to reduce the workload and protect personal safety while improving the feeding efficiency.

At the same time, the buffer rod group can also make the alkali flakes fall in a cross-flow manner, slowing down the falling speed and avoiding the problem of discharge blockage.

[0020] In the utility model, the buffer rods which are crisscrossed and distributed up and down are made of stainless steel, so that the structure is stable and does not deform, the crushing rate of the alkali flakes is improved, the particle size is uniform, it is convenient for feeding, and it is not easy to be blocked.
