Background technology
It is quite varied in the industries such as oil, chemical industry, ship, environmental protection, the application of liquid level gauge.There is glass using more at present
Glass pipe liquid level gauge, flat board liquid level gauge, magnetic float level indicator etc., these liquid level gauges are all to carry out liquid using the principle of Communicating device
Level gauging, it is relatively simple for structure.
Float level meter is the level gauging instrument designed according to Archimedes' principle and magnetic coupling principle, special
In tar liquid level in measurement container, it is made up of four essential parts：Floating drum, spring, magnet steel room and indicator.Containing big in tar
The naphthalene of amount, naphthalene fusing point is 80.5 DEG C, in measurement process, when temperature is less than 80.5 DEG C, is connected between floating drum and floating drum and spring
Chain be stained with after a large amount of tar, cause floating drum proportion to change, make measurement is inaccurate easily occur emitting groove, chain stop
Phenomena such as car, false data；And spring section easily allows the naphthalene evaporated from tar to make spring after being crystallized at spring position
It can not act and lead to not measure.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of crystallization-preventive float level meter.
In order to solve the above technical problems, a kind of crystallization-preventive float level meter described in the utility model, including holding vessel
And float level meter, the float level meter are fixedly installed in the top of the holding vessel, and stretch to the storage
Inside tank；The float level meter includes magnetic cylinder, instrument board, spring, chain and floating drum, and the spring upper end is fixedly connected on
At the top of the magnetic cylinder, lower end is fixedly connected with the chain, and the floating drum upper end is connected with the chain, and lower end is dipped in liquid
In；The instrument board is fixedly connected on the magnetic cylinder side by sensor；The crystallization-preventive float level meter also includes steaming
Steam pipe a, heat-insulation layer and heat tracing pipe, described steam pipe a one end be connecteds with the flange hole at the top of the holding vessel, the other end and
Shower nozzle is fixedly connected；The heat tracing pipe is surrounded on the outside of the magnetic cylinder, and the heat-insulation layer is coated on the outside of the heat tracing pipe.
Further, through hole is offered on the shower nozzle.
Further, the heat tracing bottom of the tube is connected with steam pipe b.
The utility model has advantages below compared with prior art：
（1）The utility model is taken wraps around heat tracing pipe of the circle using superheated steam heating in magnetic cylinder, and in heat tracing
The mode of pipe outer cladding heat-insulation layer, using 130-150 DEG C of high temperature of superheated steam, naphthalene crystal can be effectively prevented, effectively solved
Due to spring can not work caused by low temperature the problem of, there is considerable application prospect.
（2）The utility model connects steam pipe by being preset in holding vessel on flange hole, and connects and steam in steam pipe one end
The mode of vapour shower nozzle, chain and floating drum being purged with steam, ensureing that tar is not bound to chain with floating drum, ensure that essence
Accurate measurement, reliable real liquid level data is provided for production.
（3）The utility model is capable of the utilization rate of effective lifting means, and easy to maintenance succinct, and measurement data truly may be used
Lean on, avoid tar and emit groove or because chain parking phenomenon caused by liquid level numerical value inaccuracy, the clothes provided convenience for technique
Business.
