Abstract
The utility model discloses an electrothermic type heat shock resistance detection device of an insulator. The electrothermic type heat shock resistance detection device comprises a furnace body (5) which can carry out heat insulation and heat preservation, wherein the two side walls of the furnace body are provided with electric heating wires (7), a stirring fan (6) and a temperature thermocouple (8) are arranged at the top of the furnace body, the furnace body is internally provided with a metal conveyer belt (2) which can input an insulator glass piece (4) from one end of the furnace body and output the insulator glass piece (4) from the other end of the furnace body, the furnace body arranged between the metal conveyer belts is internally provided with a grid plate (10), cleaning holes (9) are formed at the inner walls of the two sides of the furnace body at intervals, and the cleaning holes are movably provided with door covers (12). The electrothermic type heat shock resistance detection device provided by the utility model has the advantages that the heating temperature in a heating furnace is uniform, flames can not be generated, the temperature control operation is convenient, the heat shock resistance picking effect of the insulator is improved, exhaust emission is not generated, and the environment is not polluted; and meanwhile, products with unqualified thermal shock resistance property are prevented from leaving a factory, and the insulator products with qualified heat resistance can not ensured not to be damaged.
Description
Technical field
The utility model relates to a kind of product quality pick-up unit, especially relates to for insulator thermal shock resistance pick-up unit.
Background technology
Explosion (self-destruction) does not at high temperature occur in its glass workpiece when insulator is moved on the line, the front all insulator glass parts that dispatch from the factory all will carry out the heat shock resistance detection, detect underproof glass workpiece product to reject heat shock resistance, guarantee the safe and reliable to operation of power transmission and transformation line.Start to adopt the heavy oil heating for insulator glass part heat shock resistance pick-up unit, but the heavy oil heating not only very easily causes gun barrel to stop up, and toxic emission and residue have greater environmental impacts, be eliminated.Made afterwards the gas heatings such as coal gas or rock gas into, because the ratio of combustion gas in practical operation and combustion air is regulated comparatively complicated, the one, cause indoor temperature inhomogeneous, cause indoor local temperature higher or on the low side, directly have influence on picking of insulator glass part heat shock resistance and select effect, the insulator resistance to sudden heating is difficult to accomplish absolutely reliable; The 2nd, the local thermal-flame formed is ejected on glass workpiece, makes the glass workpiece local temperature be much higher than detected temperatures, causes qualified glass workpiece spot annealing, even blast.
The utility model content
For the existing problem of insulator heat shock resistance pick-up unit in above-mentioned prior art, the utility model provides a kind of heating indoor temperature not only even, can not form flame, and the temperature control operation is convenient, can improve the insulator heat shock resistance detects to pick and selects effect, prevent the use of dispatching from the factory of thermal shock resistance substandard product, can guarantee again not damage heat shock resistance and detect qualified insulator product.
The technical scheme that the technical problems to be solved in the utility model is taked is: but described insulator electrothermal heat shock resistance pick-up unit comprises the body of heater of heat-insulation and heat-preservation, be provided with electrical heating wire on the two side of body of heater, be provided with agitation fan and temperature thermocouple at the body of heater top, be provided with the metal conveyor belt that the insulator glass part can be inputted and exported from the body of heater other end from body of heater one end in body of heater, in body of heater between metal conveyor belt, position is provided with screen, be arranged at intervals with cleaning eye on the inwall of described body of heater both sides, be provided with moveable door on described cleaning eye.
The utility model and traditional oil, gas formula combustion system relatively, have following advantage:
1, resistive heater is arranged on the stove inwall, does not take the stove external space, and conventional apparatus adopts the burning rifle, and the external space is had to requirement;
2, Resistant heating is stable, and temperature is more even, picks and selects better effects if;
3, generate heat by resistance wire, do not produce toxic emission, environmentally safe;
The utility model can not only make the interior heating-up temperature of heating furnace even, can not form flame, and the temperature control operation is convenient, can improve the insulator heat shock resistance picks and selects effect, can not produce toxic emission again, free from environmental pollution, can prevent that again the thermal shock resistance substandard product from dispatching from the factory simultaneously, can guarantee again not damage the insulator product that heat resistance is qualified.
