Description
Technical field
The utility model relates to a kind of high temp sintering device, specifically is a kind of high temperature rotary tube type furnace.
Background technology
In research and production, often need a kind of rotary tube furnace to prepare powder or sintered article, make powder in suspension or decline process, can fully react with atmosphere, make that perhaps sintered article place environment temperature is even, guarantee compact dimensions.The actual at present rotary tube furnace that uses, its rotating part adopts the gear-driven mode of an end to realize that this transmission causes moment of torsion bigger, the requirement on machining accuracy height substantially.Usually relatively iron and steel, quartz ampoule are relatively poor for the earthenware of tube furnace (alumina tube) thermal shock resistance in addition, rupture easily at fire door, and the life-span is lower.And the serviceability temperature of iron and steel, quartz ampoule can not satisfy the requirement of about 1700 ℃ of high temperature only about 1000 ℃.The normal way of making a joint at fracture position that adopts of people solve the boiler tube breakage problem, but its reliability is lower, also influences the slickness of boiler tube inwall.Boiler tube (alumina tube) has reached operating limit at 1700 ℃ simultaneously, and intensity is lower, and is crooked easily until fracture at high temperature.The goods that next is heavier or long in processing, the high temperature bearing of consideration boiler tube can only be thickeied boiler tube and cause the interior heat transfer of boiler tube slower, and there are the time response than length in control temperature and actual temperature, are difficult to reach the accuracy of working control temperature.Adopt the way of transmission hanging belt to solve the moment of torsion that occurs in the boiler tube rotation preferably and required the machining accuracy problem of higher, but the device center of gravity height of this structural design, operation stability and reliability are lower (for example, if will causing boiler tube to continue rotation wearing and tearing fire door, the fracture of hanging belt one end damages), so require the long-time guard on duty of special messenger during operation usually, thereby the manpower consumption is big, and installation accuracy is had relatively high expectations.In addition, for favourable high temperature axial compression stress is provided, the gap is bigger between this matching requirements fire door and the boiler tube, causes the even warm area of furnace length direction to reduce.Its boiler tube still adopts the way of joint not solve the reliability of operation near fire door.Adopt the boiler tube reinforcement to cause processed complex, size of burner hearth is strengthened, and the thickness of actual boiler tube is increased, and heat transfer causes boiler tube to rupture easily with inhomogeneous.Ceramic high temperature glue reaches operating limit and softens at 1700 ℃.Long-life and high reliability can not realize.
The utility model content
The purpose of this utility model provides a kind of high temperature rotary tube type furnace, has overcome the problem of weak point in service life, poor reliability and the process operation complexity of existing high temperature rotary tube type furnace.
The technical solution of the utility model is as follows:
A kind of high temperature rotary tube type furnace, include brace table, brace table is provided with high temperature furnace, be provided with heating in the high temperature furnace, it is characterized in that, the boiler tube of rotation is installed in the described high temperature furnace, the two ends of described boiler tube are stretched out outside the high temperature furnace respectively and are installed with stop collar, described stop collar below is respectively arranged with turning rolls, active roller and return idler that described turning rolls stop collar by rest constitute, and described active roller is in transmission connection by one-level or several grades with the variable-speed motor that is arranged on the trestle table.
Described roller outer surface adopts flexible material.
Sheath is installed at described boiler tube two ends.
There is flange at described stop collar two ends, and described active roller, return idler are between flange.
Described boiler tube two ends are equipped with the adjustable weight piece, and there is perforate at the center of balancing weight.
Buncher and power transmission shaft are installed on the described brace table, the one-level drive sprocket is installed on the buncher, one-level driven sprocket and two secondary drive sprockets, the coaxial installation secondary of the active roller on turning rolls driven sprocket are installed above the power transmission shaft; The one-level drive sprocket is connected by the first grade transmission chain bar with the one-level driven sprocket, and the secondary drive sprocket is connected by the second grade transmission chain bar with the secondary driven sprocket.
The utility model is provided with two drives at the two ends of power transmission shaft, guarantee that the boiler tube two ends are synchronous, greatly reduces boiler tube one end transmission and the moment of torsion that increases.When the both sides transmission is asynchronous, slip self-regulation takes place to synchronously between boiler tube and the turning rolls.The drive outer surface of turning rolls adopts the flexible material manufacturing, such as plastics or rubber etc., can reduce to adopt the additional moment of torsion that produces of gear mechanism transmission, for boiler tube provides a flexible support.Employing turning rolls assurance boiler tube at same horizontal level, reduces boiler tube and fire door gap at the intensification temperature-fall period, guarantees the least disadvantage of heat, guarantees the uniform temperature zone length of stove.
The utility model adopts at boiler tube and near the place of fire door sheath is installed, and reduces the temperature difference on the fire door boiler tube in the thermal shock resistance scope of furnace tube material.Sheath can adopt light material, and as alumina fibre, mullite manufacturing, ordinary circumstance is no more than about 10 centimetres and gets final product.The employing sheath can reduce the thermal loss between boiler tube and the fire door simultaneously.
The utility model adopts the way that adopts the fixed installation stop collar at the boiler tube two ends.There is flange at the stop collar two ends, can limit the position of boiler tube play.Distance that can play between the stop collar can offer boiler tube one compression less than boiler tube anamorphic stretching amount when maximum operating temperature is worked at high temperature, improves the working strength of boiler tube.Stop collar adopts manufacturings such as aluminium, steel, and the fixedly employing bolt between itself and the boiler tube holds out against and fixes.
Counterweight, the moment of flexure that boiler tube bears between the counterweigh turning rolls are installed in boiler tube of the present utility model two ends.In addition, the distance between the counterweight counter roller frame can be regulated, and conveniently is used for the different moments of flexure that the different heat treatment goods of balance increase.Counterweight is pressed on the turning rolls, can prevent boiler tube beating in transmission process, and can make between boiler tube and the turning rolls returning quickly when taking place to slide.At the counterweight center drilling, can import gas, perhaps vacuumize, realize atmosphere control.
