Abstract
A simple harmonic dust collector for monocrystalline silicon and polycrystalline silicon comprises a shell which can bear vacuum negative pressure, a foul gas chamber, a gas inlet and an ash removal opening. A patterned plate is arranged on the portion, on the upper portion of the gas inlet, in the shell and divides the shell into a clean gas chamber on the upper portion and a foul gas chamber on the lower portion. The upper end of the patterned plate is connected with the lower ends of cloth bags. The upper ends of the cloth bags are connected with movable hanging frames through connection rods. The movable hanging frames are connected with a fixed hanging frame at the upper end through springs. The two ends of the fixed hanging frame are fixed to the inner side wall of the shell. The upper portion of the shell is connected with an end socket. The end socket is provided with a gas outlet. Sealed electromagnets are arranged in the end socket. The lower ends of the electromagnets are connected with push rods. The lower ends of the push rods are arranged on the movable hanging frames. The simple harmonic dust collector has the advantages that pollution of the simple harmonic dust collector to vacuum oil is greatly reduced when the simple harmonic dust collector is used; most importantly, the continuous production time of monocrystalline silicon and polycrystalline silicon is greatly prolonged while the replacement period of vacuum oil is greatly prolonged; device, time, labor and raw material cost is greatly reduced.
Description
Technical field
The present invention relates to dust precipitator technical field in industrial production, belong to the Simple harmonic electric deduster of technique dust process in monocrystalline silicon, polycrystalline silicon industry production.
Background technology
Existing industrial dust collector can be divided into " dry type " and " wet type " two kinds of fundamental types by dustproof function power principle.Dry method dust divides with operation principle, comprises gravity type, inertia-type, centrifugal, pocket type, electrostatic etc.Wet dust removal carries out dedusting by ejecting liquid.
And sack cleaner is applicable to trap tiny, dry, non-fiber dust.High to fine dust efficiency of dust collection, generally reach more than 99%, the exigent occasion of purification can be used in.Strong adaptability, can trap the dust of various types of properties, and not because of dust the character such as ratio resistance and affect efficiency of dust collection, the dust concentration scope of adaptation is wide.Be convenient to recovered material, there is no the secondary pollutions such as pollution, waste water.But sack cleaner is generally use under atmospheric pressure state, does not also use situation under vacuum conditions.
Higher process environments is required in the production process of monocrystalline silicon, polysilicon.Whole production process needs under vacuum conditions and air pressure can not have acute variation.Raw silicon can produce the volatilization of a small amount of continuation in heating process, can cool and be condensed into fine dusts, and finally enter vavuum pump and be mixed into vacuum oil after volatile matter leaves crucible.Contaminated vacuum oil not only increases the wearing and tearing of vavuum pump, the more important thing is that vacuum oil become contaminated to a certain degree by the ability to work of extreme influence vavuum pump.Present stage monocrystalline silicon, polysilicon the continuous seepage time be about 140h, exceeding this time limit vavuum pump can affect ability to work because of the pollution of vacuum oil, causes producing the vacuum environment needed for monocrystalline silicon, production of polysilicon.Now will be forced to blowing out, and change vacuum oil and can continue to produce.
At present, the dedusting of monocrystalline silicon, polysilicon carries out dedusting by simple filter, and its dust removing effects is poor, is difficult to meet instructions for use.
Summary of the invention

Detailed description of the invention
Shown in Figure 1: a kind of monocrystalline silicon, polysilicon Simple harmonic electric deduster, it includes the housing 1 that can bear negative pressure of vacuum, bottom in housing is provided with foul smell room 2, foul smell room 2 sidewall is provided with air inlet 4, cleaning door 3 is provided with in air inlet 4 bottom, card 5 is equipped with on air inlet 4 top in housing, and housing 1 is divided into top air-purifying chamber 7 and foul smell room, bottom 2 by this card 5; This card 5 upper end is connected with cloth bag 6 lower end, and this cloth bag 6 upper end is connected with travelling cradle 9 by connecting rod 8; This travelling cradle 9 is connected with the fixing suspension bracket 11 of upper end by spring 10, and these fixing suspension bracket 11 two ends are fixed on housing 1 madial wall; Be connected with end socket 12 on the top of housing 1, this end socket 12 is equipped with gas outlet 13, also fill Packed electromagnet 14 in end socket 12, the lower end of this electromagnet 14 is connected with push rod 15, and the lower end of this push rod 15 is arranged on travelling cradle 9.
Wherein, described cloth bag 6 is by the perforate compact siro spinning technology on bottom clip and card 5, and cloth bag upper end is closed.
Wherein, some quantity cloth bags 6 connect as a whole by connecting rod 8 by travelling cradle 9.
Wherein, travelling cradle 9 is connected with fixing suspension bracket 11 by spring 10, and makes cloth bag 6 simple tension by the pulling force of spring 10.
Wherein, described air inlet 4 is connected with furnace outlet, and gas outlet 13 is connected with vavuum pump.
Wherein, the dirt gas produced during heating furnace work enters foul smell room 2 by air inlet 4, and foul smell is filtered by cloth bag 6 and entered air-purifying chamber 7, and dust impurities is stayed inside cloth bag 6, and pure qi (oxygen) finally enters vavuum pump by gas outlet 13.
Inside cloth bag 6, dust accumulation to a certain extent, and deashing device starts subregion running.Electromagnet 14 is connected with push rod 15.When electromagnet 14 rear push-rod 15 that is energized stretches out, thrust is in travelling cradle 9, and travelling cradle 9 moves down spring 8 and stretches, and cloth bag 6 becomes bent pleated state from simple tension state.When electromagnet 14 power-off rear push-rod 15 is retracted, spring 8 resilience, travelling cradle 9 moves on accelerating under spring 8 acts on, and cloth bag 6 becomes rapidly simple tension state from bent pleated state.Cloth bag is become rapidly in simple tension state procedure along with a large amount of potential energy from bent pleated state, the great number of elastic potential energy of spring 8 is converted into rapidly the elastic potential energy of cloth bag 6, in this process there is high frequency and violent string shakes in cloth bag 6 fiber, thus make the dust of attachment flake off in foul smell room 2, to reach ash-removal effect.
When dust storage in foul smell room 2, bottom is full, need blowing out and open bottom cleaning door 3 manually to remove dust.Space, foul smell room 2 is very large, and once can store a large amount of dust, therefore cleaning cycle is very long.
Filter efficiency of the present invention is high, and storage ash quantity is large, and cleaning cycle is long.Very big minimizing dust, to the pollution of vacuum oil, greatly can extend the continuous seepage time of monocrystalline silicon, polysilicon.Mechanical ash removing is effective and movement range is little, causes stove internal gas pressure to fluctuate hardly.
The above know-why being preferred embodiment of the present invention and using; for a person skilled in the art; when not deviating from the spirit and scope of the present invention; any based on apparent changes such as the equivalent transformation on technical solution of the present invention basis, simple replacements, all belong within scope.
