Abstract
The utility model discloses a device used for filling a steel ladle with sand. The device used for filling the steel ladle with the sand comprises a feed hopper and a sand filling funnel, wherein the sand filling funnel can move up and down along the steel ladle and is connected with or separated from a nozzle of the steel ladle, and a discharging pipe is arranged at the bottom end of the feed hopper. According to the device used for filling the steel ladle with the sand, when the sand filling funnel moves downwards to be connected with the nozzle of the steel ladle, the discharging pipe is connected with an opening in the top end of the sand filling funnel. The device used for filling the steel ladle with the sand has the advantages that the situations that the steel ladle can not be fully filled with sand due to the fact that sand can not be thrown accurately with hands, and drainage sand is wasted are avoided, the self-drainage rate of the steel ladle is greatly improved, the probability of casting oxygen burning is reduced, the quality of liquid steel is improved, and the number of liquid steel continuous pouring furnaces is increased.
Description
Technical field
The utility model relates to the steelmaking equipment technology, is specifically related to a kind of ladle and fills with the sand device.
Background technology
At present, horse steel ladle is filled with the sand mode and is generally: manually by hand the stuffing sand of every bag of 10kg is thrown away in the ladle nozzle of ladle bottom, thrown away the 3-4 bag at every turn; There is defective in this filling sand mode: artificial manual processing ease is thrown away stuffing sand partially, and it is discontented that fill with at the mouth of a river, causes molten steel can not burn from drawing oxygen; Can occur when serious ladle burn oxygen not start-stop water, cause producing and interrupt.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of ladle that can improve from drawing rate, reduces ladle and opens the ladle filling sand device that waters the generation of burning oxygen phenomenon.
To achieve these goals, the technical solution adopted in the utility model is:
This ladle is filled with the sand device, comprises charging hopper and can move up and down the filling sand hopper that is in access and released state with ladle nozzle along ladle; Be provided with tremie pipe in described charging hopper bottom; In the time of in the filling sand hopper moves down the access ladle nozzle, described tremie pipe joins with the top end opening of filling with sand hopper.
Be provided with the control valve that the control tremie pipe is opened and closed at described tremie pipe.
Being connected with in described tremie pipe bottom can be around tremie pipe swivel joint in relative rotation.
Described screen pack is located at charging hopper top.
Be provided with the material lid on described charging hopper top.
Described charging hopper be located at ladle fill with the sand position directly over.
The utility model has the advantage of: this ladle is filled with the sand device, and stuffing sand flows into ladle nozzle by filling with sand hopper after flowing into the filling sand hopper from charging hopper again; The charging hopper controllable flow enters to fill with the stuffing sand amount of sand hopper, and further control flows into the stuffing sand amount of ladle nozzle; Effectively avoided hand to throw away the inaccurate mouth of a river that causes, sand position and filled with the discontented generation that reaches the phenomenon of stuffing sand waste, increased greatly ladle from drawing rate, reduced to open to water and burnt the oxygen probability, improved steel quality, increased molten steel and even water the stove number; By contrast, the molten steel of crossing the LF stove uses the rate of certainly drawing behind this filling sand device to bring up to 99.1% from 92.3%, has improved 6.8%; Per month invar water from do not draw stopping of causing water number of times from use front average drop to for 5 times average≤1 time, on average reduce per month more than 4 times; Cross the rate of certainly drawing of the molten steel of LF+VD stove and average 70.1% bring up to 90.2% before use, improved 20.1%.
Direct economic benefit: the bag direct cost is about 2.5 ten thousand yuan in each, adds that baking covers all expenses and be about 30,000 yuan in each, and the bag direct benefit is 1,440,000 yuan in year saving.
Description of drawings
The below is briefly described the content of each width of cloth accompanying drawing expression of the utility model specification and the mark among the figure:
Fig. 1 is the structural representation that the utility model ladle is filled with the sand device;
Mark among the above-mentioned figure is:

The specific embodiment
The below contrasts accompanying drawing, by the description to optimum embodiment, the specific embodiment of the present utility model is described in further detail.
As shown in Figure 1, this ladle is filled with the sand device, comprises charging hopper 1 and can move up and down the filling sand hopper 2 that is in access and released state with ladle nozzle 9 along ladle 8; Fill with when moving on to ladle 8 upper position on the sand hopper 2, fill with sand hopper 2 and separate with ladle nozzle 9, corresponding, when filling sand hopper 2 moves down into ladle 8 interior location, fill with sand hopper 2 access ladle nozzles 9; Be provided with tremie pipe 3 in charging hopper 1 bottom; When filling sand hopper 2 moved down access ladle nozzle 9, tremie pipe 3 joined with the top end opening of filling with sand hopper 2, opened control valve 4 stuffing sands and can inculcate funnel 2 through tremie pipe 3 addings from charging hopper 1, and then be added in the ladle nozzle 9.
Be provided with the control valve 4 that control tremie pipe 3 is opened and closed at tremie pipe 3, control valve 4 is the control ball valve.The filling sand mode that this ladle is filled with the sand device is: manual unlocking control ball valve, and the stuffing sand in the charging hopper 1 is poured in the ladle nozzle 9 by tremie pipe 3 and filling sand hopper 2, until ladle nozzle 9 is filled into steamed bun shape, the closing control ball valve rises and fills with sand hopper 2; Inaccurate and the waste in position when this device has avoided hand to throw away sand, filling with the sand amount has also had assurance, the mouth of a river occurred never again and has filled with discontented situation.
Being connected with in tremie pipe 3 bottoms can be around tremie pipe 3 swivel joint 5 in relative rotation, and in the time of need to adding stuffing sand in the ladle nozzle 9, rotation swivel joint 5 makes it and fills with sand hopper 2 top end openings and join; When the stuffing sand within adding ladle nozzle 9 met the requirements, rotation swivel joint 5 made it remove from filling sand hopper 2 top end openings and gets final product.
Be provided with screen pack 6 in charging hopper 1, screen pack 6 can filter other foreign material in the stuffing sand, guarantees to add the quality of the stuffing sand in the ladle nozzle 9, has further guaranteed certainly drawing of ladle, and screen pack 6 is located at charging hopper 1 top.
