Description
Technical field
The utility model is related to a kind of solid article position measuring device, more particularly to a kind of for the life of heat accumulating type closed calcium carbide furnace
The material level measuring device of material bin of product.
Background technology
Heat accumulating type closed calcium carbide furnace is a kind of calcium carbide production new technique, and coke and quick lime are by crushing pressure ball high temperature preheating
After be sent to furnace of calcium carbide high temperature feed bin, then through expects pipe deliver to burner hearth occur pyroreaction generation calcium carbide.In this production process,
Because pelletizing material is by high temperature preheating, up to 1000 DEG C, temperature so high, any detection means is all difficult to hold maximum temperature
Receive, so the high temperature bin-level detection of the closed calcium carbide production new technique of heat accumulating type is always a very formidable problem.
Existing measurement material mainly uses radar level gauge in the market.Radar levelmeter is using echo and transmitting
Difference on the frequency between ripple measures thing position.Can continuously launch, continuously measure.Highest measurement temperature is hundreds of degrees Celsius, and
Need to install some other equipment such as various valves, water-cooling system, nitrogen purging additional to lower the temperature.
The technical scheme of prior art one：
Radar level gauge increases purging and realizes high temperature measurement, as shown in figure 1, increasing the radar level gauge of purging, radar material
Position meter is, to measure thing position, to pop one's head in and send higher-frequency radar ripple and run with the light velocity, when pulse runs into thing based on time stroke principle
Reflected during material surface and received by the receiver in instrument, and distance signal is converted into thing position signal.Radar wave can be even
Supervention is penetrated, and realizes that continuous material level is measured.Currently for hot environment, radar level gauge increases purging loudspeaker to reduce temperature.Nitrogen
Gas is continuously blown into sleeve pipe by blow valve port enables radar sensor loudspeaker to keep low temperature shape, it is to avoid heat passes through standpipe
Flange is passed to, then instrument is passed to by flange, radar is heated, so as to damage radar.
The shortcoming of prior art one：
1. existing radar levelmeter highest measurement temperature is hundreds of degrees Celsius, this to be installed additional to measure high-temperature material
The a series of equipment such as nitrogen purging, pressure-reducing valve, blow device, increase cost.
2. existing method needs nitrogen continuously to purge, and the consumption of nitrogen turns into very important problem, for existing
The operating modes such as field nitrogen deficiency, and do not apply to.
3. the wave energy that radar wave is launched in itself is very low, and after various purgers are installed additional, wave type energy is lower.It is situated between simultaneously
The too high rear dielectric constant of matter temperature also changes so that certainty of measurement it is difficult to ensure that.
Utility model content
The purpose of this utility model be to provide it is a kind of adapt to high temperature bin-level measurement for the closed calcium carbide of heat accumulating type

Specific embodiment
With reference to the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out clearly
Chu, it is fully described by, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole realities
Apply example.Based on embodiment of the present utility model, those of ordinary skill in the art are obtained under the premise of creative work is not made
The every other embodiment for obtaining, belongs to protection domain of the present utility model.
Material level measuring device of material bin for the production of heat accumulating type closed calcium carbide furnace of the present utility model, it is preferably specific real
The mode of applying is：
Including radar level gauge, the bottom of the radar level gauge is connected by flange with standpipe, the lower end of the standpipe
Process flange is connected with, pure quartzy dividing plate is inlaid with the endoporus of the process flange, the pure quartzy dividing plate is by the standpipe
Lower mouth all seal.
The process flange includes the two panels up and down that is bolted, the pure quartzy dividing plate be embedded in upper and lower two panels it
Between groove in.
Material level measuring device of material bin for the production of heat accumulating type closed calcium carbide furnace of the present utility model, overcomes closed calcium carbide
The problem of stove production new technique high temperature bin-level measurement.
The utility model embodiment is described in further detail below in conjunction with accompanying drawing.
Specific embodiment：
Up to 1000 DEG C, common level-sensing device instrument cannot all meet so the high-temperature material temperature of heat accumulating type closed calcium carbide furnace
Temperature high.For this kind of operating mode, the radar level gauge that the application selection can launch higher-frequency radar ripple is transformed, and forms one
The new device of kind of measurement high-temperature material, increase between radar level gauge two panels mounting flange high temperature resistant, thermal coefficient of expansion it is small,
On-deformable pure quartzy dividing plate, radar is isolated with medium, and the heat to high-temperature material forms effectively stop.Due to adopting
Higher-frequency radar ripple with frequency more than 76GHz, the beam transmission angle of transmitting is minimum, good condensing performance, and energy is concentrated, can be effective
Penetrating clapboard, obtains the strong echo of signal, completes the measurement of material position.
Mounting means is shown in Fig. 2：
Specific embodiment for the material level measuring device of material bin of heat accumulating type closed calcium carbide furnace production is above all pacified
Dress process.
The installation that high temperature bin-level improves measurement apparatus will be paid special attention to：
1. radar material position transformation device is arranged at tank deck radius 1/3, and at tank skin.Avoid being arranged on arc top tank
Center.This kind of situation can cause echo curve disorderly, and output valve is abnormal.
2. avoiding dividing plate lower section has obvious barrier, hinders probing wave smoothly to reach measured medium surface.Due to interference
It is higher than material position that signal may cause instrument to export；Or the saltus step between true material position and interference ripple signal.
3. avoid transformation device from being arranged in radar wave range of exposures and the place of stream occur.This kind of situation may cause
Instrument exports the stream reflected signal higher than material position；Or the saltus step between actual position and stream reflected signal.
High temperature bin-level improves measurement after suitable installation site is chosen, and process adpting flange is consolidated with bolt
Fixed, high temperature isolating device is compacted, after realizing feed bin sealing, you can start debugging measurement.This process without excessive manpower and materials,
Economize on resources, and maintenance work also greatly reduces in the future.
The beneficial effect that technical solutions of the utility model are brought：
1., using pure quartz as dividing plate, pure quartz material high temperature resistant is up to 1200 DEG C, high-temperature expansion system for the utility model
Number is small, be unlikely to deform, and absorbs few to higher-frequency radar ripple, can obtain the echo-signal of high-quality, dividing plate to greatest extent every
From medium, stop heat propagation, effectively realize the problem that high-temperature material is accurately measured.
2. material position is detected using isolation method, it is to avoid nitrogen purging, cost-effective, operating mode application is more extensive.
The utility model key problem in technology point and point to be protected
The utility model key problem in technology point：
With pure quartz high temperature isolating device, the heat of high-temperature material on the one hand can be effectively isolated, on the other hand pure stone
Absorption of the English material to radar wave is few, and echo-signal is strong, and isolation is increased in time, and Lei Feng's wave energy is effectively penetrated, and measurement essence is not influenceed
Degree.
