Abstract
The utility model provides a dust removal device for a top heater and a top insulation board of a polycrystalline silicon ingot furnace. The dust removal device is small in structure, light in weight and convenient to use and is suitable for daily cleaning and maintenance of the heater and the top insulation board of the ingot furnace. When the dust removal device is used for removing dust, a furnace cover is not required to be opened, and therefore, the dust removal device saves time and labor and has high efficiency. The dust removal device comprises a furnace body, wherein the top insulation board is arranged in a cavity at the upper part of the furnace body, the top heater is arranged under the top insulation board and is positioned in a locating hole in the top insulation board through a graphite electrode, the upper part of the graphite electrode is connected with a copper electrode, a graphite gas guiding tube is arranged on the top insulation board and is correspondingly arranged nearby the copper electrode, and a nozzle in the bottom of the graphite gas guiding tube faces towards the connecting place of the graphite electrode. The dust removal device is characterized in that the upper part of the top insulation board is provided with a stainless steel tube frame passageways in which are communicated with one another, and a stainless steel flange is arranged under the stainless steel tube frame.
Description
Technical field
The utility model relates to the technical field of polycrystalline silicon ingot casting furnace structure, is specially a kind of top heater and top warming plate cleaning apparatus of polycrystalline silicon ingot or purifying furnace.
Background technology
Polycrystalline silicon ingot or purifying furnace is the major equipment during polycrystalline silicon ingot casting is produced in the present photovoltaic industry, wherein the most important thing is to make its thermal field and outside furnace chamber to insulate each other, otherwise the high electric current during its work will cause great infringement to staff and equipment; And the major cause of studying carefully its conduction is as follows: the internal temperature height makes carbon felt and graphite heater produce dust easily, and just reduced the resistance between furnace chamber and thermal field when dust is bonded on the insulation tile.Therefore, we want timely dedusting.But because furnace cavity structure, the space is little, and existing dedusting method is to rely on the staff to go artificial dedusting, and it must open bell, and dedusting is time-consuming, effort, efficient are low.
Summary of the invention
At the problems referred to above, the utility model provides a kind of top heater and top warming plate cleaning apparatus of polycrystalline silicon ingot or purifying furnace, its structure is little, in light weight, easy to use, the daily cleaning that is applicable to ingot furnace well heater and top warming plate is safeguarded, need not to open bell during dedusting, dedusting is time saving and energy saving, efficient is high.
A kind of top heater of polycrystalline silicon ingot or purifying furnace and top warming plate cleaning apparatus, its technical scheme is such: it comprises body of heater, be provided with the top warming plate in the upper cavity of described body of heater, the below of described top warming plate is provided with top heater, described top heater is positioned in the pilot hole of described top warming plate by Graphite Electrodes, the top of described Graphite Electrodes connects copper electrode, described top warming plate is provided with the graphite airway, the correspondence of described graphite airway be arranged in described copper electrode near, the bottom spout of described graphite airway is towards the junction of described Graphite Electrodes, it is characterized in that: the top of described top warming plate is provided with the stainless steel pipe support of internal path mutual conduction, the below of described stainless steel pipe support is provided with steel flange, described steel flange is supported on the upper surface of corresponding described graphite airway, each described stainless steel tube flange is provided with spray orifice with being connected of described stainless steel pipe support on the steel pipe, each described spray orifice is towards the described copper electrode of correspondence, and downward-sloping upper surface towards described top warming plate, described connection steel pipe is communicated with described graphite airway, the bottom spout of described graphite airway is downward-sloping, and towards the end face of described top heater, inlet pipe is communicated with the internal path of described stainless steel pipe support.
It is further characterized in that: described graphite airway is the six roots of sensation, and described steel flange is specially six, and six described steel flanges are supported on corresponding described graphite airway;
The diameter of described spray orifice is 2mm～3mm;
The diameter of the bottom spout of described graphite airway is 2mm～3mm;
Described inlet pipe is circumscribed with magnetic valve/or ball valve.
After adopting structure of the present utility model, when the needs dedusting, the argon gas source of the gas feeds the internal path of stainless steel pipe support by inlet pipe, spray from the bottom spout of graphite airway, the spray orifice that connects on the steel pipe respectively then, because the end face of bottom spout aligning Graphite Electrodes and top heater, spray orifice are towards warming plate surface, top, its argon gas of jetting can reach the dedusting effect, its structure is little, in light weight, easy to use, the daily cleaning that is applicable to ingot furnace well heater and top warming plate is safeguarded, need not to open bell during dedusting, dedusting is time saving and energy saving, efficient is high.
