Description
Technical Field
The utility model belongs to the technical field of metallurgical equipment, and particularly relates to an outlet airflow conveying pipe for a flux vertical mill.
Background
The flux vertical grinding system has the main tasks that wind sand, quartz and cold materials are mixed according to the proportion, then are ground by a vertical mill, collected by a bag dust collector, conveyed to a metallurgical furnace flux bin by a bin pump, and finally are added into a furnace. The outlet airflow conveying pipe of the vertical mill is a welded integrated pipeline. The abrasion leakage to the air flow duct is severe due to the strong quartz polishing. The service cycle is only 2 months, the elbow is worn and leaked, and the leakage part is gradually expanded to the periphery. And the maintenance and replacement time is 3-5 days, which cannot be completed in the maintenance period of the metallurgical furnace per month, and the normal production of the system is affected. Because the maintenance and replacement time is insufficient, the normal production of the vertical mill system can be ensured only through daily maintenance repair welding, so that the maintenance quantity of the system is large, the system is stopped for at least 2-3 hours in the maintenance repair welding process, and the normal start-up production of the system is affected to a certain extent. The discharging pipe of the vertical mill is high-altitude, and certain safety risks exist in the maintenance repair welding process. The field material leakage not only causes pollution to the environment, but also increases the cleaning amount of staff in the post.
Disclosure of Invention
The utility model aims to solve the problems that the flux vertical mill has strong quartz polishing property, serious abrasion and leakage to an airflow conveying pipe, frequent system shutdown and maintenance are needed, normal production of the system is affected, and spare part consumption and large maintenance amount are caused.
In order to achieve the above purpose, the present utility model adopts the following technical scheme:
the utility model provides a be used for flux vertical mill export air current conveyer pipe, includes the mill export deformation pipe that passes through flange joint with flux vertical mill export, mill export deformation pipe passes through flange joint mill export straight tube, mill export straight tube passes through flange joint mill export return bend, mill export return bend passes through flange joint cloth bag dust collector import straight tube, cloth bag dust collector import straight tube passes through flange joint cloth bag dust collector import deformation pipe, cloth bag dust collector import deformation pipe is connected with cloth bag dust collector, be equipped with the reinforcement steel sheet on the mill export return bend.
The utility model has the following beneficial effects:
the utility model adopts a flange sectional connection structure, is convenient to overhaul and replace, and solves the problems of serious abrasion and leakage of the air flow conveying pipe due to strong quartz polishing property of the flux vertical mill, frequent system shutdown and overhaul are required, normal production of the system is affected, and spare part consumption and large overhaul and maintenance amount are caused. The abrasion part of the outlet airflow conveying pipe can be turned by 180 degrees, a set of spare parts can be recycled and reused for a plurality of times, the utilization rate of the spare parts is effectively improved, maintenance and overhaul are convenient, the cost is saved, the production operation rate of the system is improved, and the normal production of the metallurgical furnace is ensured.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model;
in the figure: the device comprises a 1-mill outlet deformation pipe, a 2-mill outlet straight pipe, a 3-flange, a 4-mill outlet bent pipe, a 5-reinforced steel plate, a 6-cloth bag dust collector inlet straight pipe, a 7-cloth bag dust collector inlet deformation pipe, an 8-flux vertical mill and a 9-cloth bag dust collector.
Detailed Description
The utility model is further described below with reference to the drawings and the detailed description.
As shown in fig. 1, an airflow conveying pipe for an outlet of a flux vertical mill comprises a mill outlet deformation pipe 1 (deformation pipe with square one end and round one end) connected with an outlet of the flux vertical mill 8 through a flange 3, wherein the mill outlet deformation pipe 1 is connected with a mill outlet straight pipe 2 through the flange 3, the mill outlet straight pipe 2 is connected with a mill outlet bent pipe 4 through the flange 3, the mill outlet bent pipe 4 is connected with a cloth bag dust collector inlet straight pipe 6 through the flange 3, the cloth bag dust collector inlet straight pipe 6 is connected with a cloth bag dust collector inlet deformation pipe 7 (deformation pipe with square one end and round one end) through the flange 3, and the cloth bag dust collector inlet deformation pipe 7 is connected with a cloth bag dust collector 9.
The air flow conveying pipe is made of delta= (16+4) mm and lining surfacing wear-resistant layer material (delta=4mm). The back of the mill outlet elbow pipe which is easy to wear is reinforced by adopting a plurality of steel battens 5 with the thickness of 20mm for secondary welding, so that the wear resistance is ensured. The flange segmented connection structure is adopted among the pipelines, in the production operation, the parts which are leaked by the air flow scouring wear can be turned 180 degrees after maintenance repair welding, the parts which are not easy to be eroded by the air flow are turned and then are changed to the parts which are easy to be eroded by the air flow, the parts are disassembled and replaced after being repeatedly used for three times, one set of spare parts can be circularly and repeatedly used for three times, and the spare part utilization rate is high. The utility model effectively improves the utilization rate of spare parts, is convenient to maintain and overhaul, improves the production operation rate of the system and ensures the normal production of the metallurgical furnace.
