Abstract
The utility model discloses an electric heater for a screw shaft. The electric heater for the screw shaft comprises a conveying hopper (1). A discharge outlet (2) is arranged at the bottom of one end of the conveying hopper. The screw shaft (3) is disposed in the conveying hopper. Two ends of the screw shaft are connected with a base (5) through bearing blocks (4). A straight electric heating tube (6) is disposed in the screw shaft which is a hollow shaft. Two ends of the straight electric heating tube are connected with the screw shaft through heat-resistant bearings (7). The existing hot kerosene heating is replaced by electric heating. Therefore, a kerosene circulating system and a kerosene heating device both complex in structure are not needed, the structure of the heating device is simplified greatly, strict sealing of the hot kerosene is not needed, sealing difficulty is reduced, and production cost is reduced. The electric heater for the screw shaft is simple in structure and convenient in processing and mounting. Heating temperature can be achieved by regulating power, and the regulation is convenient. Leakage in heating with the kerosene is avoided. A hot kerosene system is also omitted.
Description
Technical field
the utility model relates to a kind of electric heater unit of screw shaft, belongs to the insulation helical feed technical field of steelworks with the electrode material.
Background technology
The used electrode of
steelworks is manufactured by electrode factory specially; In course of conveying, need to keep about 150 ℃ temperature and make the used material of electrode, in course of conveying, be bonded at the defeated material of influence efficient on screw shaft and the defeated hopper to avoid material.Existing heating arrangement is to adopt hot coal oil to heat; Establish cavity in the screw shaft of rotation, be connected with high temperature kerosene in the cavity, therefore oil inlet and oil outlet pipe need be set; Static oil inlet and oil outlet pipe need seal with the screw shaft of rotation; Sealing difficulty is big, complex structure, but also special kerosene heating system need be set.So existing to be used to carry the type of heating of the screw shaft of making the electrode material still be not ideal enough.
Summary of the invention
The purpose of
the utility model is, a kind of electric heater unit of screw shaft is provided, and to simplify the structure of heating system, reduces sealing difficulty, and cancellation kerosene heating system reduces heating cost.
The technical scheme of the utility model:
The electric heater unit of
a kind of screw shaft comprises defeated hopper, and the bottom of defeated hopper one end is provided with discharging opening; Be provided with screw shaft in the defeated hopper, the screw shaft two ends are connected with support through bearing seat; Said screw shaft is a hollow shaft, is provided with straight tube shape electric heating tube in the screw shaft; The two ends of straight tube shape electric heating tube are connected with screw shaft through heat-resisting bearing.
In
aforementioned means, be provided with adapter sleeve in the endoporus at said screw shaft two ends, screw shaft is connected with the support axle key with axle drive shaft with adapter sleeve, and fixes through jackscrew.
In
aforementioned means, said pivot shaft is a hollow tubular, and said axle drive shaft and screw shaft bonded assembly one end are hollow tubular, are provided with heat-resisting bearing in the hollow tubular, and heat-resisting bearing and straight tube shape electric heating tube are rotationally connected; Axle drive shaft is connected with support through bearing seat with pivot shaft.
In
aforementioned means, said axle drive shaft and pivot shaft are provided with sealing flange, and sealing flange and defeated hopper both ends of the surface are through bolted connection.
In
aforementioned means, said straight tube shape electric heating tube is provided with positioning seat, and positioning seat is connected with support.
In
aforementioned means, said straight tube shape electric heating tube one end is provided with connection box.
compared with prior art; The utility model has replaced the heating of existing hot coal oil with electro heat; Therefore do not need baroque kerosene circulating system and kerosene heating arrangement, simplified the structure of heating arrangement greatly, need not carry out strict encapsulation process yet hot coal oil; Reduce the leak free difficulty, reduced productive costs.It is simple in structure for the utility model, processing, easy for installation; The heating-up temperature adjustable power obtains, and is easy to adjust; Avoided the oil leakage phenomenon when heating with heat kerosene; But also reduced the heat kerosene system.
