Description
Technical field
The utility model belongs to technical field of metallurgy industry, discloses a kind of materials flow setting device.This device is used for the adjusting of bulk material materials flow amount.
Background technology
Blast furnace materials flow setting device is the key equipment of blast furnace bell-less furnace roof.The materials flow setting device of present domestic use adopts external structure formation, especially large blast furnace.Its structure of the material flow gate of domestic introduction is that oil cylinder promotion jointed connecting rod driving sphere is split the valve plate unlatching, and the accuracy requirement of connecting rod is higher, and its structure is also complicated, and manufacture difficulty is bigger.
Summary of the invention
The purpose of this utility model provides a kind of materials flow setting device, to satisfy the needs that high charging flow is regulated.
The utility model is to be supported on the setting device casing by hydro-cylinder, one end of hydro-cylinder links to each other with transmitting gear, transmitting gear and transmitting gear engagement, turning axle is housed on transmitting gear, one end of turning axle puts in the casing and bow beam is housed respectively, is separately installed with valve plate on the bow beam, and measuring element is housed on the turning axle, in the middle and upper part of casing the center material guiding pipe is housed, valve plate is positioned at the end opening of center material guiding pipe.It can regulate the materials flow amount of blast furnace the utility model, also can make down the materials flow center to enlarging all around.Its compact construction, transmission are accurately reliable, and the efficient height is advanced practical, safe and reliable, are that desirable and practical device is regulated in present blast furnace materials flow.
The purpose of this utility model realizes in the following way: the materials flow setting device is made up of hydro-cylinder, gear, connecting rod, axle, valve plate, center material guiding pipe, bow beam, casing, measuring element etc.This materials flow setting device promotes the turning axle rotation by the hydro-cylinder that is supported on the casing by connecting rod, drives bow beam and valve plate and rotates, and drive another bow beam and valve plate rotation by geartransmission, with the function that realizes that valve plate is split.Cooperate automatic control can realize reaching the purpose of regulating the materials flow amount by measuring element, and can make the opening shape of valve plate satisfy the function that the center begins blanking.
Of the present utility modelly be characterised in that it can satisfy the adjusting of high charging flow, promptly cooperate, rationally regulate the blanking amount, also can make materials flow start from the center blanking with automatic control.Its compact construction, transmission are accurately reliable, the efficient height.Be that simple and practical device is regulated in present materials flow.
Description of drawings
Fig. 1 is a structural representation master sectional view of the present utility model.
Fig. 2 is an A-A partial enlarged drawing of the present utility model.
Fig. 3 is a B-B partial enlarged drawing of the present utility model.
Among the figure, part 1 is a hydro-cylinder, part the 2, the 3rd, and transmitting gear, part the 4, the 5th, turning axle, part the 6, the 7th, valve plate, part 8 are center material guiding pipes, part the 9, the 10th, bow beam, part 11 are that casing, part 12 are measuring elements.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Hydro-cylinder 1 is supported on the setting device casing, one end of hydro-cylinder 1 links to each other with transmitting gear 2, transmitting gear 2 and transmitting gear 3 engagements, turning axle 4,5 is housed on transmitting gear 2,3, one end of turning axle 4,5 puts in the casing 11 and bow beam 9,10 is housed respectively, is separately installed with valve plate 6,7 on the bow beam 9,10, and valve plate 6,7 one-tenths be layout up and down, in the middle and upper part of casing 11 center material guiding pipe 8 is housed, valve plate 6,7 is positioned at the end opening of center material guiding pipe 8.
Its groundwork principle is: the hydro-cylinder 1 that is supported on the setting device casing promotes transmitting gear 2, turning axle 4 rotations, the bow beam 9 that drive links to each other with turning axle 4 rotates, the valve plate 6 that is fixed on the bow beam 9 is rotated, transmitting gear 3 is housed on turning axle 5, rotate by the engagement driven rotary axle 5 of transmitting gear 3 with transmitting gear 2, bow beam 10 that links to each other with turning axle 5 and the valve plate 7 that is fixed on the bow beam 10 rotate, valve plate 6,7 two supports is on casing 11, measuring element 12 is housed on the turning axle 4, materials flow drops to the valve plate 6 that structure is overlapping arc opposite opened by center material guiding pipe 8, on 7, can control valve plate 6 by measuring element 12,7 opening degree.The opening shape of valve plate 6,7 is strengthened gradually by the center, can make materials flow concentrate on the center and begin blanking.
Characteristics of the present utility model are that it can regulate the materials flow amount of blast furnace, promptly cooperate with automatic control, rationally regulate the blanking amount, also can make materials flow start from the center blanking.Its compact construction, transmission are accurately reliable, and the efficient height is advanced practical, safe and reliable, are that desirable and practical device is regulated in present blast furnace materials flow.
