Description
Technical field
The present invention relates to a kind of furnace of calcium carbide of strip resistance setter, belong to calcium carbide production unit technical field.
Background technology
Calcium carbide, chemical name is carbide of calcium (CaC2), and it is one of main raw material of organic synthesis industry.The production method of industry calcium carbide has electric heating process and the hot method of oxygen two kinds.Electric heating process produces calcium carbide mainly using lime and coke as raw material, drop into furnace of calcium carbide according to a certain percentage, discharged by three-phase electrode in furnace of calcium carbide and produce the raw material such as electric-arc heating coke and Wingdale, make it under the state of melting, the chemical reaction of series of complex occur and make.Adopt electric heating process to produce in the process of calcium carbide, in furnace of calcium carbide, furnace temperature height and stability directly affect quality and the energy consumption size of calcium carbide.In actual production process, electrode inserts furnace charge, due to electrode and the contact short circuit of furnace charge, the reason such as avalanche, charge composition gasification of furnace charge, can cause the fluctuation that flame current generation is very large, therefore need the depth location of quick adjustment electrode, flame current just can be made to remain in certain scope.
Summary of the invention
Object of the present invention is exactly for the problems referred to above, provides a kind of furnace of calcium carbide of strip resistance setter, by regulating the resistance of furnace charge, makes electrode be in optimal depth location all the time.
The technical solution used in the present invention is: it comprises body of heater and seals the bell be arranged at body of heater top, described bell is provided with some electrodes that can move up and down in body of heater, described bell is provided with the drive unit that can move up and down, output terminal bottom described drive unit is fixedly connected with organic frame, described frame is fixedly connected with some insulcretes, and described insulcrete is between two adjacent electrodes.
Preferred structure further, described bell is provided with case, and described drive unit is installed on case top, and described frame is arranged in case.
Preferred structure further, described drive unit is hydro-cylinder.
Preferred structure further, described frame comprises body frame and circumferentially radial equally distributed some pressing plate connected vertically with body frame, and described insulcrete is vertically fixedly connected on pressing plate.
Preferred structure, is provided with bracing frame between described body frame and pressing plate further.
Preferred structure further, described insulcrete is made up of several insulation rods of row, and described each insulation rod is fixedly connected on pressing plate respectively.
Preferred structure further, described insulation rod is stupalith.
Preferred structure further, described case covers in Shelf External and is circumferentially uniformly distributed setting.
The invention has the beneficial effects as follows: relative to regulating electrode depth separately, the present invention and electrode depth regulate with the use of, when electrode and the contact short circuit of furnace charge, the reason such as avalanche, charge composition gasification of furnace charge, when causing flame current that very large fluctuation occurs, inserted the interelectrode resistance of depth adjustment of furnace charge by the insulcrete in the present invention, electrode depth is remained in optimum range effectively.
