A kind of autoclave material-level detecting device
Technical field
The utility model relates to the autoclave material-level detecting device.
Background technology
It is that hyperbaric oxygen leaches a difficult problem in the smelting process that the autoclave material level detects always.During operate as normal, be in the environment of a kind of high temperature, high pressure, many foams, many disturbances in the autoclave.And the material level of autoclave is a most important technological parameter, can not adopt traditional material level detection method to measure.Have both at home and abroad by the nuclear radiation instrument and detect the autoclave material level.But the autoclave volume that hyperbaric oxygen leaches in the smelting process is big, and the still wall thickness needs stronger radiation source just can penetrate kettle, on-the-spot installation inconvenience, and the technological operation environment also is greatly affected (radiation), and costs an arm and a leg, and the general user is difficult to accept this detection mode.
Summary of the invention
The utility model pick-up unit technical issues that need to address are: under the environment of high temperature, high pressure, many foams, many disturbances, measure the material level of autoclave accurately and reliably, be convenient to installation and maintenance simultaneously.
The technical scheme that the utility model pick-up unit is adopted: be provided with a sleeve, sensor is installed in sleeve, sleeve is provided with a steam inlet that connects the external high pressure steam pipe.
Use when installing, open one at the autoclave top and detect the hole, above-mentioned autoclave material-level detecting device is installed in the detection hole.
During work, the high pressure steam that feeds enters in the still by sleeve lining, the convex edge of sleeve lining bottom makes the spittle and ore pulp not to adhere on the level-sensing device probe front end of high pressure steam conductance to the level-sensing device probe, thereby guarantees the operate as normal of radar level gauge.
The utility model pick-up unit is simple and reasonable, convenient processing and manufacture, and comprehensive use cost significantly descends than nuclear radiation instrument.

Embodiment
Referring to Fig. 2, the autoclave material-level detecting device that the utility model provides comprises sensor 3, adopt the high temperature radar level gauge in the present embodiment, be provided with a sleeve 6, sensor 3 is installed in sleeve 6, sleeve 6 is provided with a steam inlet 4 that connects the external high pressure steam pipe.
Use when installing, open one at the autoclave top and detect hole 5, detecting the above-mentioned autoclave material-level detecting device of hole 5 installations.By flange bolt sleeve 6 and sensor 3 are fixed on the detection hole 5.
