Abstract
The utility model relates to a device for continuously smelting titanium slag and accurately feeding in a direct-current closed arc furnace. The device is formed by connecting a nitrogen sealing system ( 1), a bin ( 2 ), a manual gate valve ( 3), a pneumatic flapper valve ( 4), a weighing bin ( 5 ), a weighing sensor ( 6 ), a screw feeder ( 7) and a feeding pipe ( 8) in turn from top to bottom. The device can continuously constantly feed, the feeding speed is adjustable, the material is accurately weight and mixed before being fed into the furnace and then the material is quickly fed into the furnace to prevent the material from being liquated and the automation degree is high.
Description
Technical field
The utility model belongs to the accurately apparatus structure technical field of control of titanium slag smelting process feeding method, particularly continuous-feeding.
Background technology
The electric furnace of producing titanium slag at present mainly contains open type, semi-hermetic type, closed; Preceding two kinds belong to batch production; What adopt is the mode of disposable feed, and adopts the sealed furnace of this method to belong to continuity production, employing be the mode of continuous-feeding; Realize the quantity-produced purpose, should cooperate method and device the continuous smelting titanium slag accurate feeding of the airtight electric arc furnaces of direct current.
Summary of the invention
The purpose of the utility model is to overcome prior art still not have and can for the continuous smelting titanium slag of the airtight electric arc furnaces of direct current the defective of accurate feeding be provided continuously, can be the device of the continuous smelting titanium slag accurate feeding of the airtight electric arc furnaces of direct current continuously and provide a kind of.
The purpose of the utility model realizes through following technical scheme.
The utility model adopts nitrogen-sealed system, feed bin, manually push-pull valve, pneumatic push-pull valve, the storehouse of weighing, LOAD CELLS, screw(-type) feeder, feed pipeline connect and compose from top to bottom in regular turn.
The utility model advantage be continuously constant feeding, accurately weighing and burden, delivery rate is adjustable, carry out accurate measurement and mixing, go into that stove prevents the material segregation, shortens the batching time, automaticity is high fast going into the stokehold.
Description of drawings
Fig. 1 is that the accurate feeding apparatus structure of the utility model connects sketch map.
The specific embodiment
The device of the continuous smelting titanium slag accurate feeding of the airtight electric arc furnaces of a kind of direct current,
The utility model adopts nitrogen-sealed system 1, feed bin 2, manually push-pull valve 3, pneumatic push-pull valve 4, the storehouse 5 of weighing, LOAD CELLS 6, screw(-type) feeder 7, feed pipeline 8 connect and compose from top to bottom in regular turn.
The utility model occupation mode:
The first step; When bin-level reach low when spacing LOAD CELLS pass low weight numerical value, the DCS Long-distance Control provides charging and instructs, material is delivered to the feed bin 2 of weighing through nitrogen-sealed system 1; The nitrogen-sealed system prevents that CO from overflowing, and makes feed smooth and easy;
Second step, close when manually push-pull valve 3 keeps the opening-wide state maintenance always, be full of the storehouse 5 of weighing through the quick fill material of the switching of pneumatic push-pull valve 4;
In the 3rd step, DCS transmits a signal to feeding system according to the technique initialization parameter, and after feeding system was received feeding signal, the control buncher drove the feeding device charging, and serves as the control target with the feed setting value, constant feeding speed;
In the 4th step, the material when the storehouse 5 of weighing in drops to the agreement gravimetric value, and the DCS Long-distance Control is opened pneumatic push-pull valve 4 automatically, and the interior materials of feed bin 2 storehouse 5 of will weighing is rapidly filled up; Around here, screw(-type) feeder 7 keeps constant feeding ground duty under the control of instrument, after material is filled again in the storehouse of weighing (5), close pneumatic push-pull valve 4 automatically;
In the 5th step, material arrives screw(-type) feeder 7 through the LOAD CELLS of being installed on the storehouse 5 of weighing 6, through On-line Control screw(-type) feeder 7 mass transport is carried out batch mixing to feed pipeline 8, arrives stove interior 9 at last; Work so circularly, reach the purpose of continuous, the accurate weighing and burden of ability, its automaticity is high.
Claims (1)
1. the device of the continuous smelting titanium slag accurate feeding of the airtight electric arc furnaces of direct current; It is characterized in that, adopt nitrogen-sealed system (1), feed bin (2), manual push-pull valve (3), pneumatic push-pull valve (4), the storehouse of weighing (5), LOAD CELLS (6), screw(-type) feeder (7), feed pipeline (8) to connect and compose in regular turn from top to bottom.
