Description
Technical Field
The utility model belongs to thermotechnical auxiliary equipment field especially relates to a buggy funnel of reduced iron tunnel cave charging system.
Background
The development of the direct reduced iron tunnel kiln loading and unloading system in China goes through two stages of manual operation and mechanization. The starting stage of the loading and unloading system of the reduced iron tunnel kiln is mainly completed manually. The operator uses a measuring tool to weigh the weight of the iron powder and the coal powder, uses an iron spoon to respectively load the iron powder and the coal powder into a fire-resistant tank mould, then draws out the stainless steel mould, and seals the top of the fire-resistant tank with the coal powder. Because of the pure manual operation, the labor intensity of workers is high, the dust of coal dust in a workshop is large, and the working environment is poor. The company declares a mechanical charging device with a patent number of ZL201320784883.0 for a direct reduced iron tunnel kiln in 2013, 12 and 04, greatly reduces the labor intensity of workers, improves the working environment of the workers, saves manpower and improves the economic benefit of enterprises. This charging system comprises five stations: the first station is used for loading outer ring coal dust, the second station is used for loading inner ring coal dust, the third station is used for loading middle ring iron powder, the fourth station is used for loading a mold, and the fifth station is used for supplementing materials. The coal powder funnel of the charging system of the reduced iron tunnel kiln is a bridge and a link which are connected with a coal powder metering barrel and inner and outer ring coal powder stations and is one of the core components of the charging system.
Disclosure of Invention
The utility model aims at providing a pulverized coal funnel of a reduced iron tunnel kiln charging system which has reasonable structure, simple use, smooth charging, small labor intensity and high working efficiency for the market.
The technical scheme of the utility model is that: the funnel body is of a double-layer flow dividing structure, the inner layer is a circular tube filled with inner-ring pulverized coal, the outer wall is funnel-shaped, a conical flow guide ring is arranged between the middle lower part of the circular tube and a bell mouth of the funnel body, the upper part of the conical flow guide ring is fixedly connected to the circular tube, and the lower part of the conical flow guide ring is provided with a guide circular ring. The height of the pilot ring is 10-12 mm. An outer ring coal powder circular charging opening is formed between the funnel-shaped outer wall and the circular pipe, between the conical diversion ring and the guide circular ring, and the lower part of the funnel can be conveniently and accurately inserted into the charging tank by about 10 mm.
The utility model has the advantages that: the funnel is divided into two parts by the round pipe and the flow guide ring arranged at the center of the funnel, so that one funnel can respectively fill pulverized coal to different parts in the charging tank, the aim of one object with multiple purposes is fulfilled, and the funnel has the advantages of reasonable structure, simplicity in use, smoothness in charging, low labor intensity, high working efficiency and the like, and has wide popularization and application values.
The present invention will be further described with reference to the accompanying drawings.
Drawings
FIG. 1 is a schematic view of the cross-sectional structure of the present invention;
fig. 2 is a schematic view of the bottom view of the present invention.
In the figure: the coal dust filling device comprises a funnel body 1, a circular pipe 2, a conical guide ring 3, a guide circular ring 4, an inner ring coal dust filling inlet 5, an outer ring coal dust filling inlet 6, an inner ring coal dust filling outlet 7 and an outer ring coal dust filling outlet 8.
Detailed Description
As shown in fig. 1 and 2, the pulverized coal hopper of the charging system of the reduced iron tunnel kiln comprises a hopper body 1, wherein the hopper body 1 is of a double-layer flow distribution structure, the inner layer is a circular tube 2 filled with pulverized coal at the inner ring, and the outer wall is funnel-shaped. Set up cone-shaped water conservancy diversion ring 3 between the horn mouth of lower part and funnel body 1 in this pipe 2, cone-shaped water conservancy diversion ring 3 lower part has set up and has led positive ring 4, forms outer lane buggy ring shape charging opening, and makes things convenient for the funnel below to accurately insert in the charging can within 10 millimeters.
When the utility model is implemented, the pulverized coal is dried and then directly put down to the feeding hopper of the bucket elevator, the bucket elevator directly lifts the pulverized coal to the storage bin, the pulverized coal of the storage bin is ready to be canned at any time, the charging machine is arranged under the storage bin, when a first hydraulic flashboard of the charging machine is pulled open, the pulverized coal of the storage bin can be discharged into the metering cylinder and is filled in the metering cylinder, the filling volume is calculated pulverized coal volume (at the moment, the metering car body is lifted and tightly props against a lower flat steel plate of the fixed cylinder) and waits for an empty tank kiln car with a mold to arrive, when the empty tank kiln car with the mold enters a first station through the hydraulic drawstring machine and is accurately stopped at a charging position, at the moment, the first station can be used for charging the pulverized coal, the metering car body is descended under the action of the hydraulic cylinder, a pulverized coal hopper arranged below the metering cylinder is butted with a mold head in the charging tank and extends into the mold for 10 mm (the butting allowable error is within, after butt joint, the hydraulic flashboards arranged between the metering cylinder and the pulverized coal hopper are pulled open under manual operation through electric appliance control, pulverized coal falls into the mold cylinder from the annular charging port of the pulverized coal at the outer ring due to dead weight, the outer ring of the mold is filled with the pulverized coal at one time, and therefore the task of the first station is completed. Then the coal powder enters the inner ring coal powder station of the next station, the actions are repeated, the coal powder falls into the die cylinder from the cylindrical charging port of the coal powder of the inner ring by self weight, the inner ring of the die is filled with the coal powder at one time, and thus the task of the second station is completed.
