A high-pressure phosphorus removal auxiliary device

Abstract

The present invention relates to the field of steel strip dephosphorization equipment, and in particular to a high-pressure dephosphorization auxiliary device, which includes a dephosphorization bin, which is provided with vibrating rollers and high-pressure rejectors respectively close to its left and right ends, and the numbers of the two are respectively There are two sets of pinch rollers on both sides of each vibrating roller, and a grinding and washing machine is respectively set between the two adjacent pinch roll sets and next to a pinch roll set close to the outlet end of the dephosphorization bin. The vibrating roller includes an upper beam frame, a transfer cylinder, a planetary hollow roller and a frequency conversion motor. The roller shaft is connected to the inside of the transmission cylinder. At least 1 / 3 of the outer surface of the planetary hollow roller is frictionally fitted with the inner wall of the transmission cylinder. The frequency conversion motor is installed outside the transmission cylinder and connected with the planetary hollow roller. All are provided with a supporting beam plate, and the invention can greatly reduce the cost of dephosphorization of steel strips.

Description

technical field [0001] The invention relates to the field of steel strip dephosphorization equipment, in particular to a high-pressure dephosphorization auxiliary device. Background technique [0002] Oxide skin will be produced on the outer surface of the steel strip, and the oxide scale on the surface of the steel strip must be cleaned before processing. At present, domestic enterprises generally use chemical pickling methods (such as: hydrochloric acid, sulfuric acid, nitric acid, hydrofluoric acid) to remove the scale on the outer surface of the steel strip, which seriously pollutes the environment; descaling by shot blasting can partially remove the scale on the outer surface of the steel strip , but the dust pollution is serious, generally equipped with dust removal equipment, and it is difficult to meet the process requirements, and it is easy to cause pits on the surface of the steel strip. [0003] According to the above problems, after retrieval: Chinese Patent No...

[0003] According to the above problems, after retrieval: Chinese Patent No.: CN201610054044.1 discloses a multi-channel sandblasting dephosphorization process. mouth, so a large amount of corundum supply is required. From the perspective of long-term operation, its output energy consumption (corundum) is too large, which will increase the production cost of the enterprise; and due to the excessive number of nozzles, the accumulation speed of the waste sand layer under the steel belt Fast, requires frequent manual shutdown processing, which will affect the output
