Abstract
The utility model relates to the field of alloy electric furnace distributors. A weighting mechanism of a chromium iron alloy electric furnace distributor comprises a weighting bucket (13), a roller weighting unit (17) and an absorber (14). The roller weighting unit (17) is mounted below the outlet of the weighting bucket (13) through the absorber (14). The weighting mechanism on a chromium iron alloy electric furnace distributor has the advantages of convenient and even distribution, high automation level and high production efficiency.
Description
Technical field
The utility model relates to alloy electric furnace dosing unit field.
Background technology
Ferrochrome is the important additives in the steel products, and the ferrochrome product can increase the wear resistance of steel, improves the mechanical propertys such as hardness, elasticity, thermotolerance and erosion resistance of steel.Preparation of raw material is the critical process link in the process for processing of high quality ferrochrome.Weighing mechanism on the existing ferrochrome electric furnace dosing unit is to be made of bucket, weight sensor, the gate and the electric pushrod that are fixed on the bucket bottom.Electric pushrod connects the outside of bucket by anchor.Electric pushrod comprises motor, push rod and limit switch, and push rod one end connects motor output end, and the other end is by the folding of contiguous block connection gate and control gate, and limit switch is installed on the push rod.The vertical entrance location of bucket is in the below of electric and magnetic oscillation blender loader outlet, the electrical signal control motor action of weight sensor.
The defective that weighing mechanism on the existing ferrochrome electric furnace dosing unit exists is: 1. what scale hooper adopted is the device that electric pushrod drives gate, electric pushrod is at the volley owing to reasons such as overload meeting flexural deformation, influence advancing or setback of push rod, in addition, dead angle in the valve system get stuck easily or discharging obstructed, and be stuck in raw material powder in the mechanism or the piece material can make the gate rotary resistance increase, cause rotate malfunctioning; 2. judge that the limit switch that gate opens or closes needs often to adjust, do not install and damaged easily at that time, cause to open the door-the out of control of action that close the door, influenced normally carrying out of raw material weighing process; 3. the bar gate type blowing makes raw material skewness on belt conveyor, and the blowing amount was big when gate had just been opened, and reduces rapidly then, is unfavorable for the mixture control of plurality of raw materials, can cause the working of a furnace technology instability in the smelting process.
Summary of the invention
The purpose of this utility model is the technological deficiency that exists for the weighing mechanism that solves on the existing ferrochrome electric furnace dosing unit, provides a kind of blanking evenly convenient, helps the weighing mechanism on the ferrochrome electric furnace dosing unit of mixture control of plurality of raw materials.
In order to realize above-mentioned purpose, the utility model has adopted following technical scheme:
Weighing mechanism on a kind of ferrochrome electric furnace dosing unit comprises bucket, cylinder weighing device and vibroshock, and cylinder weighing device is installed in the below of bucket outlet by vibroshock.
As preferably, described cylinder weighing device by about two vibroshocks be suspended on the below of bucket outlet, cylinder weighing device comprises motor, weighing cylinder and weighing belt, electric motor driving weighing cylinder and the action of weighing belt.
As preferably, described bucket inner wall smooth, outlet is truncated conical shape.
As preferably, described bucket top is provided with weight sensor, the motor action of the electrical signal index drum weighing device of weight sensor.
Owing to the weighing mechanism on a kind of ferrochrome electric furnace dosing unit that has adopted above-mentioned technical scheme, have the following advantages: 1. improved proportioning accuracy, owing to adopted cylinder weighing device, the weighing signal is steady, device structure is simple, the discharge process smoothness has particularly been improved the batching situation of the high smart fine ore of water content, has improved control accuracy and stability greatly; 2. the raw material blanking is even, has improved compounding effect, and it is erratic to have solved on the employing gate blowing belt conveyor feed distribution, causes plurality of raw materials to mix uneven problem, has guaranteed the stable of the working of a furnace technology in the smelting process.3. improve level of automation and economic benefit, blending process accurately, in time and stable, significantly reduced because batching is forbidden the stokehold auxiliary material adjusting work carried out, improved labour productivity.In sum, it is evenly convenient that the weighing mechanism on this ferrochrome electric furnace dosing unit has blanking, level of automation height, advantage of high production efficiency.

Embodiment
Make a detailed explanation below in conjunction with 1 pair of embodiment of the present utility model of accompanying drawing.
Weighing mechanism on a kind of ferrochrome electric furnace dosing unit as shown in Figure 1 reconstitutes quantity sensor 12 by bucket 13,17,2 vibroshocks 14 of cylinder weighing device and 3 and constitutes.Cylinder weighing device 17 is installed in the below of bucket 13 outlets by vibroshock 14.Cylinder weighing device 17 by about two vibroshocks 14 be suspended on the below of bucket 13 outlets, cylinder weighing device 17 comprises motor, weighing cylinder 16 and weighing belt 15, electric motor driving weighing cylinder 16 and 15 actions of weighing belt.Bucket 13 inner wall smooths, outlet is truncated conical shape.Be evenly distributed with 3 weight sensors 12 by 120 ° on bucket 13 tops, the motor action of the electrical signal index drum weighing device 17 of weight sensor 12.Scale hooper 13 is truncated conical shape, and inner bulkhead is smooth, does not have the dead angle that raw material is piled up, and discharge process is smooth and even, is fit to very much mix.
The foregoing description only is a this patent embodiment preferably, and the structure that all employing the technical program are described, feature and the variation on its spiritual principle, modification all belong to the protection domain of this patent.
