Abstract
The utility model relates to a feeding device for a ferrosilicon smelting submerged arc furnace. The feeding device comprises a feed bin on the top of the furnace, an upper gate valve of a discharging tube, a constant hopper, a lower gate valve of the discharging tube, a vertical discharging tube, an oblique discharging tube and a cushion cylinder, wherein the two discharging gate valves are vertically arranged on the constant hopper and interlocked, and if one of the gate valves is not in place, the other gate valve cannot be opened. Thus, the discharging quantity at each time is maximally controlled to the capacity of the constant hopper, the cushion cylinder which is full of raw materials and has the length of 300-500mm is retained on the end part of a vertical segment of the discharging tube, the following raw materials directly impact the raw materials in the cylinder after the raw materials are full of the cushion cylinder, and thus, rapid abrasion of the discharging tube caused by the fact that the raw materials such as silica and the like directly impact the discharging tube is avoided.
Description
One, technical field
The utility model relates to the feeding device of the hot stove in a kind of ferrosilicon smelting ore deposit, belongs to silicon smelting equipment technical field.
Two, background technology
In ferrosilicon smelting is produced; Need that big content of starting materials is added the burner hearth tissue through variety of way and smelt production; Especially the silica raw material input amount of 40-120mm granularity is bigger; Along with the continuous development of modern enterprise and the continual renovation of industrial equipment, the growth requirement of modern enterprise has been satisfied not in hand-fed, and material pipe automatic distributing becomes development trend.Known material pipe automatic distributing mode be with silica and reductive agent thereof from the hot-top, ore deposit higher position (roof material distributing post), in stove, carry silica and reductive agent thereof through filling tube.In operation process, have following problem: baiting valve lost efficacy when not closing, and the raw material that whole feed bin can occur once all descends in stove, causes charge level too high, influenced the ordinary production operation of the hot stove in ore deposit.Silica gouging abrasion to the material pipe in the process of logical charge tube is bigger, and particularly the gouging abrasion to inclined tube and straight connector place is bigger, and maintenance is changed frequent, and serious restriction is produced.
Three, summary of the invention
The purpose of the utility model provides the feeding device of the hot stove in a kind of ferrosilicon smelting ore deposit; By gate valve 2 on furnace top bin, the tremie pipe, decide gate valve 4 under feed bin 3, the tremie pipe, vertically tremie pipe 5, the oblique feeding device formed of tremie pipe 6 and dashpots 7; Two blanking gate valves are set deciding feed bin up and down; Two intervalve interlockings, a gate valve pass is not in place, and another gate valve is not opened.So just guaranteed that each blanking amount is maximum controlled in deciding the feed bin holding capacity of bin; The material pipe vertically end of section is reserved the long raw material dashpots of 300-500mm; After raw material is full of dashpots; Follow-up raw material directly impacts an interior raw material, thereby has avoided raw materials such as silica directly to impact the quick wearing and tearing that the material pipe causes the material pipe.Reach and improve the feed safety and prolong the material pipe purpose in work-ing life.
The utility model is implemented by following technical scheme; It comprises gate valve 2 on furnace top bin 1, the tremie pipe, decide gate valve 4 under feed bin 3, the tremie pipe, vertically tremie pipe 5, tiltedly tremie pipe 6 and dashpots 7; Gate valve 2 on furnace top bin 1, the tremie pipe, decide under feed bin 3, the tremie pipe gate valve 4 and vertically all connect between the tremie pipe 5 with flange; Vertically adopt arc welding between tremie pipe 5 and the oblique tremie pipe 6; Vertically tremie pipe 5 stretches to the hot stove burner hearth in ore deposit, welds oblique tremie pipe 6 at vertical tremie pipe 5 apart from bell 4-6 rice and enters in the burner hearth, and tiltedly tremie pipe and vertical tremie pipe is connected mouth 300-500mm at the bottom of the vertical tremie pipe of weld bond distance; And will vertically expect to manage in the end mouth shutoff welding, form the long raw material dashpots 7 of a 300-500mm.
During work, raw materials such as silica drop into furnace top bin, are full of and decide feed bin 3.Blanking when operation, gate valve on the tremie pipe 2 closed open gate valve 4 under the tremie pipe after putting in place, the hot stove of decide in the feed bin 3 in part or all of raw materials input ore deposit.This time blanking finishes, and gate valve under the tremie pipe 4 is closed open gate valve 2 on the tremie pipe after putting in place, puts into raw material such as silica and is full of and decides feed bin 3, then will go up gate valve again and be closed to the position.So circulation can be avoided because of last (descending) when the gate valve fail close does not go up, and too much raw material (greater than deciding bunker capacity) pours in burner hearth, influences the working of a furnace.
Next, to the burner hearth course of conveying, when arriving vertical tremie pipe 5 and oblique tremie pipe 6 interfaces, raw material is filled the dashpots 7 under the full interface earlier to raw materials such as silica from the material pipe, and just suitable then inclined tube falls into burner hearth.Follow-up silica raw material is not directly pounded the material pipe but is pounded on the raw material at dashpots in the process that falls, reduced the wearing and tearing of material pipe greatly, reduces the maintenance frequency, has ensured the continuous operation of the hot stove in ore deposit.
Compare advantage and the positively effect that has with known technology:
(1), the utility model setting is decided feed bin, and two blanking gate valves is set above that down.Two intervalve interlockings, a gate valve pass is not in place, and another gate valve is not opened.So just having guaranteed that each blanking amount is maximum is controlledly deciding the feed bin holding capacity of bin.
(2), material pipe tilting section and the vertical interface of section is not connected on vertical section end, vertically the long raw material dashpots of 300-500mm is reserved in the end of section material pipe.After raw material was full of dashpots, follow-up raw material directly impacted an interior raw material, thereby had avoided raw materials such as silica directly to impact the quick wearing and tearing that the material pipe causes the material pipe.
Four, description of drawings
Fig. 1 is the structure iron of the utility model.1 is that furnace top bin, 2 is that gate valve on the tremie pipe, 3 is that gate valve under the tremie pipe, 5 is that vertical tremie pipe, 6 is oblique tremie pipe for deciding feed bin, 4 among the figure, and 7 is dashpots.
Five, embodiment
As shown in Figure 1, it comprises gate valve 2 on furnace top bin 1, the tremie pipe, decides gate valve 4 under feed bin 3, the tremie pipe, vertically tremie pipe 5, oblique tremie pipe 6, dashpots 7.Gate valve 2 on furnace top bin 1, the tremie pipe, decide under feed bin 3, the tremie pipe gate valve 4 and vertically all connect between the tremie pipe 5 with flange; Vertically adopt arc welding between tremie pipe 5 and the oblique tremie pipe 6; Vertically tremie pipe 5 stretches to the hot stove burner hearth in ore deposit; Welding oblique tremie pipe 6 at vertical tremie pipe 5 apart from bell 4-6 rice enters in the burner hearth; Tiltedly tremie pipe and vertical tremie pipe be connected vertically mouth 300-500mm at the bottom of the tremie pipe of weld bond distance, and will vertically expect to manage in the end mouth shutoff welding, form the raw material dashpots 7 of a 300-500mm length.
