Abstract
The utility model discloses the drying blanking device of a kind of covering slag, including blanking bin, air feed system, suction tube and vacuum cleaner；Being provided with air supply device on the lower end sidewall of described blanking bin, the upper port at blanking bin is provided with taper cover plate, is provided with feed hopper on the upper end sidewall of blanking bin, and taper cover plate is provided with air outlet, and described vacuum cleaner connects air outlet by suction tube.By arranging heater in blanking bin, make material the most heated drying during blanking is collected, and then make dust and feed separation, and again by being passed through the drying further to material of hot blast degree from the bottom of blanking bin, and by vacuum cleaner, dust is collected；This utility model is reasonable in design, easy to use, and dust removing effects clearly, substantially increases the quality of production of material.
Description
Technical field
This utility model relates to metallurgy powder production field, especially relates to the drying blanking device of a kind of covering slag.
Background technology
Known; in continuous casting produces; in addition to the strand that cast section is less; substantially it is required for using covering slag to coordinate submersed nozzle; thus the direct motion of the quality and continuous casting to ensure strand is carried out; i.e. in casting process, the covering slag constantly added on crystallizer molten steel face can play the role that 1, adiabatic heat-insulation prevents heat radiation；2, separate air, prevent the oxygen in air from entering molten steel generation secondary oxidation, affect the quality of steel；3, absorb dissolving from molten steel, float to the field trash of slag interface, cleaning molten steel；4, there is one layer of slag film to play lubrication between crystallizer wall and solidified shell, reduce resistance of billet withdrawal, prevent the bonding of scull and copper coin；5, the air gap between filling green shell and crystallizer, improves Billet；But; it is powder material owing to producing the covering slag being prepared from; its granule is less, deal is lighter; and after producing molding; its high humidity, stickiness are strong, need it is carried out drying and processing, so that powder and dust separation; finally give clean powder, and covering slag and dust well can not be carried out high efficiency separation by existing furnace drying method.
Summary of the invention
In order to overcome the deficiency in background technology, the utility model discloses a kind of covering slag and dry blanking device.
For achieving the above object, this utility model adopts the following technical scheme that
The drying blanking device of a kind of covering slag, including blanking bin, air feed system, suction tube and vacuum cleaner；Being provided with air supply device on the lower end sidewall of described blanking bin, the upper port at blanking bin is provided with taper cover plate, is provided with feed hopper on the upper end sidewall of blanking bin, and taper cover plate is provided with air outlet, and described vacuum cleaner connects air outlet by suction tube.
Further, the medial wall of blanking bin is provided with ring shaped heating mechanism.
Further, at the lower port of blanking bin, blanking device of weighing it is provided with.
Further, described suction tube is bellows.
Further, described vacuum cleaner is the aspiration of negative pressure device.
Further, described heater is resistive heater.
Further, described air supply device is aerator or hot-air blower.
Owing to using technical scheme as above, this utility model has the advantages that
By arranging heater in blanking bin, make material the most heated drying during blanking is collected, and then make dust and feed separation, and again by being passed through the drying further to material of hot blast degree from the bottom of blanking bin, and by vacuum cleaner, dust is collected；This utility model is reasonable in design, easy to use, and dust removing effects clearly, substantially increases the quality of production of material.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
In figure: 1, blanking bin；2, weigh blanking device；3, air supply device；4, vacuum cleaner；5, suction tube；6, conical lid；7-feed hopper；8-heater.
Detailed description of the invention
Can be explained in more detail the present invention by the following examples, open the purpose of this utility model is intended to protect all changes and improvements in the range of this utility model, and this utility model is not limited to the following examples:
As it is shown in figure 1, the drying blanking device of a kind of covering slag, including blanking bin 1, air supply device 3, suction tube 5 and vacuum cleaner 4；Being provided with air supply device 3 on the lower end sidewall of described blanking bin 1, the upper port at blanking bin 1 is provided with conical lid 6, is provided with feed hopper 7 on the upper end sidewall of blanking bin 1, and conical lid 6 is provided with air outlet, and described vacuum cleaner 4 connects air outlet by suction tube 5.
The medial wall of blanking bin 1 is provided with the heater 8 of annular.
Blanking device 2 of weighing it is provided with at the lower port of blanking bin.
For ease of installing and location, suction tube 5 is bellows.
Described vacuum cleaner 4 is the aspiration of negative pressure device.
Described heater 8 is resistive heater.
Described air supply device 3 is aerator or hot-air blower, i.e. can only ventilate in feed bin downwards, owing to material is in blanking bin blanking process, heated by heater, dust meeting material is the most separated, so ventilating, dust is moved at the taper cover plate on top, and by vacuum cleaner, dust is collected again；Or according to practical situation, time as wetter in material ratio, if not realizing being kept completely separate of dust and material after heater, hot blast, further material drying can be passed through in blanking bin.
This utility model is by arranging heater in blanking bin, make material the most heated drying during blanking is collected, and then make dust and feed separation, and again by being passed through the drying further to material of hot blast degree from the bottom of blanking bin, and by vacuum cleaner, dust is collected；This utility model is reasonable in design, easy to use, and dust removing effects clearly, substantially increases the quality of production of material.
The non-detailed portion of this utility model is prior art, therefore this utility model is not described in detail.
