Description
Technical field
The present invention relates to a kind of for automatic transport product (such as glass, solar cell, semiconductor crystal wafer or analog) by the thermal treatment zone in stove with the device of heat-treating.
Background technology
The known conveyer system being provided for heat-treating in practice, the load-carrying unit of its bearing product at least partially through stove.At this, pending product mainly carry on the conveyor belt or on port plate to pass through stove.According to prior art, this heat treatment comprises the following steps:
-product is placed on conveyer belt/port plate;
-continuously or stage by stage be transported in baking oven;
-product is heated together with conveyer belt/port plate;
-once reach technological temperature: keep this temperature, heat treatment, mechanical treatment and/or chemical treatment etc.; And
-product is cooled together with conveyer belt/port plate.
The heat treated shortcoming of known use conveyer system is, because most of applied energy is usually used for heated transportation band or port plate, therefore needs a large amount of energy.Usually, the thermal mass of product is more much smaller than the thermal mass of conveyer belt or port plate.In addition, the key wear of conveyer belt or port plate creates, this is because these conveyer belts or port plate receive thermal stress or mechanical stress.Conveyer belt must absorb all pulling force produced by the friction between conveyer belt and stayed surface, particularly in the hot-zone of stove.In hot-zone, conveyor belt material deliquescing, the tape of conveyer belt is out of shape and conveyer belt is elongated, aging and distortion.Port plate may be damaged by the Mechanical Contact between plate, and corner angle may be easy to damage or snap.Another shortcoming is, the low heat endurance of conveyer belt, adds by conveyer belt or port plate mill pressure on a support surface and produces particle.
Summary of the invention
On this basis, the problem to be solved in the present invention be improve further this for automatic transport product with the device of heat-treating in a furnace, to avoid described shortcoming.In order to reach this object, need openly a kind of conveyer system for heat treated article, this conveyer system has in structure and simply designs, needs little energy to carry described product, occurred a small amount of wearing and tearing and therefore achieved longer service life.
This problem is solved according to the present invention, in the present invention, be provided with the conveyer system with haulage gear, this conveyer system has two parallel guide rails, and in the present invention, in order to carry pending product, at least two load-carrying units are stretched between described two guide rails transverse to conveyor direction.
According to another instruction of the present invention, guide rail is arranged in the cold-zone of stove.Therefore, when carrying pending product, guide rail is only subject to mechanical stress.Therefore, thermal stress and thermal wear is not had to occur.
Another configuration of the present invention provides each guide rail and has substantially oval design.Except ellipse, if enough radiuses can be obtained around the corner, then that can also have rectangle or the trapezoidal form of each guide rail.The top surface being used for carrying pending product of guide rail is advantageously suitable for the shape of stove, but on the contrary, the lower surface of guide rail can be any shape.By making the end circle as much as possible of flat top surface and lower surface, the load-carrying unit of tensioning between the guide rails can almost frictionally not turn to.Therefore the respective shapes of guide rail makes load-carrying unit constantly circulate.
According to another instruction of the present invention, guide rail has the design of specular.Which ensure that the distance between two guide rails keeps constant.
According to another embodiment of the present invention, in guide rail, be furnished with the multiple bearing parts installed movably.By multiple bearing part, multiple product can also process in a furnace simultaneously.Moveable installation makes bearing part such as be turned at the rounded ends place of guide rail by guide roller.This makes bearing part repeatedly around guide rail.
Another instruction of the present invention provides load-carrying unit and can be attached to each bearing part on diverse location.In order to reach this object, be provided with multiple grooves disposed adjacent one another on the load bearing member, such as slot or hole, described groove is used for accommodating load-carrying unit.This makes the distance between load-carrying unit be variable.Load-carrying unit can hang into the length of applicable pending product.Like this, product is freely supported by least two load-carrying units, this means by conveyer belt grind on a support surface pressure and produce less desirable particle reliably avoided.
The bearing part that another configuration of the present invention provides each guide rail is connected to each other by haulage gear.Continuous print haulage gear makes a series of bearing part move along guide rail.Herein, the distance in guide rail between bearing part can become to be applicable to pending product by unrestricted choice.For this reason, bearing part can utilize any fastener attachment to continuous print haulage gear.
According to another configuration of the present invention, haulage gear is preferably designed to carrier chain.This makes oval guide rail be able to optimum cycle by carrier chain.Because guide rail is arranged in the cold-zone of stove, thus special high-temperature material is not needed for carrier chain.Which also reduces material cost.Haulage gear can also have the design of steel wire rope, steel band (belt) or steel bar (strip) alternatively.
According to another instruction of the present invention, load-carrying unit is designed to tension steel wire.Like this, the stayed surface of pending product and the radiation capture-effect on product all minimize.The little quality of tension steel wire also results in saves material compared to conveyer belt.Tension steel wire keeps low-down and adds thermal losses and cooling loss due to their low thermal masses.By the accurate location on product tension steel wire between the guide rails, the use as the strapping of delivery element becomes unnecessary, therefore also avoid belt deliquescing and distortion in the hot-zone of stove.
Another configuration of the present invention provides tension steel wire and is preferably made up of stainless steel alumel, thus provides best mechanical stability and heat endurance at up to the temperature of 1250 DEG C.This there will not be problem, also can not occur mechanical stress and/or thermal stress in the material when making tension steel wire pass the hot-zone of stove.
Finally, another instruction of the present invention is provided tension steel wire and is loaded by spring and be tensioned, wherein each root tension steel wire preferably by Connection Element, connected by least one helical spring, to produce elastic force.This makes pending product carry by not having sagging tension steel wire.For this reason, each helical spring spring constant is matched with applied weight.
