Multi-point single-injection lubricating oil adding device and method for Raymond mill

Abstract

The invention relates to a multi-point single-injection lubricating oil adding device and method for a Raymond mill. An existing Raymond mill is short in reliable operation time period, so that powder conveying material supply is insufficient, oil needs to be added once after equipment operates for 6 hours, the actual oil adding time is 2 hours, the production requirement is seriously restricted, and the system operation time is short. The device comprises a universal pipe distributor installed on the upper portion of an internal main machine of the Raymond mill, and is characterized in that the universal pipe distributor is connected with an outward pipe, the diameter of the outward pipe is 22 mm, the universal pipe distributor is connected with an oil cavity through the universal pipe, the oil cavity is a bearing oil conveying cavity of a lifting roller assembly of the Raymond mill, and the diameter of the bearing oil conveying cavity is 20 mm. The Raymond mill lifting roller assembly comprises an oil cavity, a group of oil supply branch pipes are arranged on the oil cavity, the Raymond mill lifting roller assembly comprises a group of grinding rollers, bearing oil nozzles are fixed on the grinding rollers, and the oil supply branch pipes are in pipe connection with the bearing oil nozzles. The multi-point single-injection lubricating oil adding device is used for the Raymond mill.

Description

technical field [0001] The invention relates to a multi-point single-injection lubricating oil adding device and an adding method for a Raymond mill. Background technique [0002] Our company is a circulating fluidized bed unit. The limestone conveying system adopts the method of spraying calcium in the dry desulfurization furnace. The finished limestone powder is ground by the Raymond mill pulverizing system. It is supplied to the unit for desulfurization needs. To meet the technical indicators required by our company, to meet production, to achieve the purpose of reducing consumption and saving, this Raymond mill has a short reliable operation period, which leads to insufficient supply of materials for milling and conveying. The equipment needs to be refueled once every 6 hours of operation. 2 hours, the maximum utilization time is 16 hours per day, which has severely restricted the production needs, resulting in short system running time.

[0002] Our company is a circulating fluidized bed unit. The limestone conveying system adopts the method of calcium spraying in the dry desulfurization furnace. The finished limestone powder is ground by the Raymond mill pulverizing system to supply the desulfurization needs of the unit. The Raymond mill system equipment can Reach the technical indicators required by our company, meet the production requirements, and achieve the purpose of reducing consumption and saving. The Raymond mill has a short reliable operation time period, resulting in insufficient supply of materials for powder milling and conveying. The equipment needs to be refueled once every 6 hours. The actual time for refueling is 2 hours, and the maximum utilization time per day is 16 hours, which has seriously restricted production needs, resulting in short system running time
