Abstract
The invention discloses a single crystal storage tank which comprises a vent valve, an upper cover, an air inlet pipe, a dirt stopping baffle, a bracket, an exhaust pipe, an exhaust funnel and a storage tank. The single crystal storage tank is characterized in that the storage tank takes the shape of a cylinder with a bottom part, a flange plate structure is arranged at the top end of the storage tank, the bottom of the storage tank is fixedly mounted on the bracket through a bolt, the exhaust funnel is fixedly mounted at the bottom of the center in the storage tank, the bottom of the vent funnel is connected with the exhaust pipe, the upper cover is fixedly mounted on a flange plate of the storage tank through a bolt, the vent valve is mounted at the upper end of the center of the upper cover, the air inlet pipe is welded on the right side surface of the storage tank, the axis of the air inlet pipe is lowered than the top surface of the exhaust funnel, the dirt stopping baffle is in an L-shape, and is welded above a hole of the air inlet pipe on the right side surface of the interior of the storage tank. The single crystal storage tank is shorter in overall pumping time, and has the advantages that the effect is greatly improved, the furnace pressure is stabilized, the cleaning times of the storage tank are reduced, and the cleaning time and the manpower are saved.
Description
Technical field
The present invention relates to solar-photovoltaic technology field, particularly relate to a kind of monocrystalline hold-up vessel.
Background technology
All to carry out thoroughly clearing up body of heater gas exhaust duct and hold-up vessel after each stove crystal pulling terminates, to meet the unobstructed of next stove crystal pulling exhaust.All the time all ensure that the heating of about 60KW is to meet the normal growth of monocrystalline because be about in 50-60 hour in whole crystal pulling, thus also produce the volatile matter after burning all the time accordingly.Taken away by one piece, vacuum pump when positive normal open argon gas (rare gas element that should not react) thus ensure that the cleaning in stove.Volatile matter after burning and the gas gas exhaust duct the first step by body of heater under the draft of vacuum pump focuses in hold-up vessel; Hold-up vessel inner hollow upper end connects gas exhaust duct, and bottom connects vacuum pump; Bosom has a cylindrical filtration, and its Main Function volatile matter is stopped stay in hold-up vessel, and allow the gas be drawn out of enter vacuum pump and finally take the external world to, so whole principle is exactly roughly.But through fact proved that hold-up vessel inside can stop most of volatile matter directly to enter vacuum pump inside because of the existence of filtering net really, also have impact on the stable of single crystal growing furnace internal pressure to a great extent simultaneously.Its reason be volatile matter to reach in hold-up vessel under the effect of suction in various degree be attracted to filtering net, with the most mesh of growth of time by volatile matter close and cause portion gas can not be brought to the external world in time, so pressure in single crystal growing furnace will influence of fluctuations one-tenth crystalline substance or cause crystal to break up and down.
Summary of the invention
According to above deficiency, the invention provides a kind of structure simple, stablize furnace pressure and time saving monocrystalline hold-up vessel.
For achieving the above object, monocrystalline hold-up vessel of the present invention, main contents are: comprise purging valve, upper cover, inlet pipe, hinder dirty baffle plate, support, vapor pipe, aiutage and hold-up vessel, it is characterized in that, described hold-up vessel is band round-ended cylinder shape, hold-up vessel top is flange plate structure, be mounted by means of bolts on bottom described hold-up vessel on support, described support is welded by shaped steel, pedestal lower end has 4 or 6 supporting legs, described aiutage to be fixedly mounted in hold-up vessel bottom central position, aiutage length is 900mm, be connected with vapor pipe bottom aiutage, described vapor pipe is provided with dop, described upper cover is mounted by means of bolts on hold-up vessel ring flange, upper end, upper cover central position is provided with purging valve, on described inlet pipe welding hold-up vessel right flank, inlet pipe axis is lower than aiutage end face 180 ~ 260mm, inlet pipe is provided with dop, the dirty baffle plate of described resistance is " L " type, hinder dirty baffle plate and be welded on 5 ~ 10mm above the air inlet pipe hole of hold-up vessel inner right side face.
As preferably, described upper cover and hold-up vessel contact position are added with gasket.
As preferably, the described hold-up vessel degree of depth is 950mm.
The effect that the present invention is useful is: decrease whole evacuated time, significantly improve effect; Stabilize furnace pressure; Reduce the clearing times to hold-up vessel, save cleaning time and manpower; Ensure that volatile matter at utmost deposits to pot bottom, reduce the pollution to vacuum pump oil.
