Description

Last charging polycrystalline furnace
Technical field
The present invention relates to the production of polysilicon equipment technical field, more particularly, relate to a kind of charging polycrystalline furnace of going up.
Background technology
Polysilicon is very important intermediates in the silicon product industrial chain.In recent years, the develop rapidly of silicon solar cell has driven the development of polysilicon industry, and then causes market increasing to the demand of polysilicon.In order to satisfy the big demand in present market, practice thrift the production cost of polysilicon simultaneously, in the existing polysilicon production process, through the body of heater volume of increase polycrystalline furnace, thus the output of increase polysilicon.
Polycrystalline furnace can be divided into the charging polycrystalline furnace and the polycrystalline furnace of feeding down through the difference of charging method; Wherein: on the polycrystalline furnace of feeding in the process that bell is opened, bell is risen through hoisting appliance; Push bell open around turning axle then, put in the burner hearth of body of heater thereby realization will fill the crucible of silicon material.Yet in order to satisfy the big demand of polysilicon, the existing body of heater of going up the charging polycrystalline furnace also increases, and causes the area of body of heater, bell and weight to increase thereupon.In order to realize the unlatching to bell, designing a kind of convenient opener of opening bell is the main direction that designs at present.
Existing a kind of opening ways of going up the bell of charging polycrystalline furnace is the method for first kindling lid back rotation.Hoisting appliance mainly drives the turbine rotation through motor rotation, and turbine rotation drives worm screw and rotates, and worm screw connects optical axis, and the rotation of worm screw promotes optical axis rises, and the rising of optical axis and then with the bell jack-up that makes progress finally realizes lifting of bell.Bell leaves body of heater after rising, and relies on the optical axis that is arranged on bell one side to support, and make optical axis crooked because the gravity of bell produces moment of flexure on optical axis this moment.Because optical axis is set in the axle sleeve; The bending of optical axis makes the frictional force of optical axis and axle sleeve increase; Cause optical axis can't normally cooperate with worm screw; And then making optical axis in the uphill process from axle sleeve, produce shake, the frictional force when serious between optical axis and the axle sleeve causes optical axis to rise, and finally causes bell to open.
Therefore, from above-mentioned bell opening process, can draw, design a kind of charging polycrystalline furnace of going up; With the moment of flexure that reduces to produce owing to bell gravity; And then reduce the frictional force between optical axis and the axle sleeve, and guarantee stable the opening of bell, be present those skilled in the art's problem demanding prompt solution.
Summary of the invention
