Abstract
A non-material bell top charging device of a blast furnace pertains to the technical field of a charging device of a metallurgical blast furnace. The technical problem to be solved is to provide a roof charging device of a surveymeter which does not do harm to a human body and can correctly detect the practical condition of the detected matters in a charging bucket. The technical proposal is that the device comprises a distributor, a lower sealed valve, a material flow gate, a charging bucket, an upper sealed valve, a stock stop, and a receiving hopper. A radar level measurement instrument which comprises a bracket and a measure probe is also provided in the device. The bracket is arranged at one side of the upper plane of the charging bucket body. A measure hole is opened on the plane, and the size of the aperture is matched with the diameter of the radar light wave emitted by a measure probe. The included angle between the central axis of the measure probe and the vertical direction is about 17plus or minus 5 degrees. The non-material bell top charging device of a blast furnace can directly detect the practical condition of the detected matters without damages to the human body or any interference to peripherals. The device can be conveniently arranged and reliably operated.
Description
Technical field
The utility model relates to a kind of blast furnace top charging equipment, belongs to the metallurgy high furnace loading device
Technical field.
Background technology
In metallurgy high furnace top charging work, the inventory of surveying in the batch can is very important, and it can guarantee that reinforced process accurately carries out according to processing requirement, thereby makes the quality of matallurgical products reach requirement.In case owing to grasp inaccurate to the inventory in the batch can, reinforced time, speed and reinforced quantity can not meet processing requirement fully, will the composition and the performance of product be made a big impact, so operator and the frequent inventory of understanding in the batch can of technician's needs.In production process in the past, the inventory of surveying in the batch can generally all adopts the gamma-rays level indicator that is installed in the batch can both sides, this gamma-rays level indicator employing radio isotope caesium 137 is made radioactive source and is outwards launched gamma-rays, receive by the corresponding receiving sensor that is installed in the batch can opposite side again, this detecting pattern is that correlation detects, detected material between launching device and receiving trap will be blocked the receiving trap reception and transmit, thereby receiving trap will produce switch signal.The shortcoming of this gamma-rays level indicator is that gamma-rays very easily damages human body, and safety coefficient is low, can only judge from switch signal simultaneously to have or not detected material in the batch can, and can not detect detected material reality what.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of being equipped with not to be had injury, can detect the top charging equipment of the detector of the practical situation of detected material in the batch can exactly human body.
The technical scheme that solves above-mentioned alleged technical problem is: a kind of blast furnace bell-less top charging equipment, it is made up of distributor, lower seal valve, material flow gate, batch can, upper sealing valve, material stop valve, hopper, it also is equipped with the radar type material level survey meter, the radar type material level survey meter is made up of support and measuring sonde, support is installed in upper end planar one side of batch can tank body, have a metering orifice on this plane, the diameter of the radar light wave of the size in aperture and measuring sonde emission is complementary.
Above-mentioned blast furnace bell-less top charging equipment, the angle α of the central axis of the measuring sonde of described radar type material level survey meter and vertical direction are 17 ± 5 degree.
Above-mentioned blast furnace bell-less top charging equipment, the radar beam of radar type material level survey meter emission is the hertzian wave of 6.3GHZ.
The blast furnace bell-less top charging equipment that adopts this structure is the practical situation of detected material in the visual inspection discharge tank well, and the radar type material level survey meter without any injury, does not have any interference to peripheral equipment to human body yet, and is easy for installation, reliable.
Description of drawings
Fig. 1 is an one-piece construction synoptic diagram of the present utility model
Embodiment
As we can see from the figure, this blast furnace bell-less top charging equipment, it is made up of distributor 1, lower seal valve 2, material flow gate 3, batch can 4, upper sealing valve 5, material stop valve 6, hopper 7.In order accurately to understand the situation of the material in the batch can 4, and overcome in the past that the gamma-rays level indicator very easily damages human body, the shortcoming that safety coefficient is low, it has also installed the radar type material level survey meter, the radar type material level survey meter is made up of support 9 and measuring sonde 8, support 9 is installed in upper end planar one side of batch can 4 tank bodies, on this plane, have a metering orifice 10, the diameter of the radar light wave of the size in aperture and measuring sonde 8 emissions is complementary, and the central axis of the measuring sonde 8 of present embodiment and the angle α of vertical direction are 17 ± 5 degree.
The radar type material level survey meter of this blast furnace bell-less top charging equipment adopts non-contact measurement, and its probe collection projector and receptor are one.Probe antenna is with the electromagnetic impulse signal of the form emission 6.3GHz of wave beam, and the echo that measured medium reflects is received by antenna.Electronic unit is by analyzing, calculate radar pulse from being transmitted into the working time of reception, providing the distance of dielectric surface of popping one's head in, and exports corresponding analog quantity current signal, can detect the actual state of detected material well intuitively.
