The silica power feeding device has the advantages that the environmental problem of the domestic feeding operation at present is solved, harm of dust to operators in the process operation is avoided; feeding is achieved by means of self-gravity of the device, investment of manpower in the feeding process is reduced; concentrated feeding is achieved, waste and pollution of raw materials in the feeding profess are avoided; the whole silica powder feeding device is simple in structure, convenient to use and easy to install, and production cost is greatly lowered.
Description
One, technical field
The utility model relates to a kind of silica flour feeding device, and it belongs to field of polysilicon production.
Two, background technology
The silica flour feeding device synthesizes requisite feeding device in the workshop at the production of polysilicon trichlorosilane, has played vital effect in the reinforced process of silica flour.At present a lot of trichlorosilane manufacturer produces silica flour reinforced workshop section at trichlorosilane and generally adopts the mode that hand-fed, vacuum pump are taken out, nitrogen is carried to feed in raw material, consume too much manpower and materials under this working condition, and pollute and waste virtually in reinforced process the raw material silica flour.Generally face following problem for the silica flour feed way is at present domestic:
1, artificial directly broken bag: a, severe operational environment, easily cause the dust injury; B, feed time are long, affect the continuous and steady operation of system; In c, reinforced process, unrestrained phenomenon is serious, causes the waste of raw material, has strengthened production cost.
2, the vacuum pump mode of taking out: a, drop into vacuum pump (corollary system), increased fixedly input; B, there is the mechanical fault problem, increased the maintenance cost of equipment; C, there is the line clogging phenomenon, affects the continuous and steady operation of system.
3, nitrogen is carried: a, nitrogen are carried and corollary system, have increased fixed investment; B, carry nitrogen expense used high, increased production cost; C, there is the line clogging phenomenon, affects the continuous and steady operation of system.
Three, the content of utility model
The purpose of this utility model is to provide a kind of novel silica flour feeding device, and it has advantage: one, in operating process environment without dust; Two, device construction is simple, has reduced unnecessary mechanical fault problem; Three, can realize concentrated feeding in raw material, reduce the wastes and pollution of raw material; Four, simple to operate, safe and reliable.
the purpose of this utility model is achieved like this: it comprises loading hopper, the sealing cone, jacking system, sealing vertex of a cone bar consists of, the loading hopper bottom is taper, the silica flour discharge port is left in the bottom, the sealing cone is taper, the sealing cone is placed in loading hopper, the trim of sealing cone overlaps with loading hopper sealed bottom face, jacking system is doline, be connected with sealing vertex of a cone bar on jacking system, sealing vertex of a cone shank diameter is bored the bottom circular groove less than sealing, sealing cone bottom circular groove diameter is identical with loading hopper bottom discharge mouth diameter, sealing vertex of a cone bar is connected by back up pad with jacking system.
The utility model silica flour feeding device, it has the following advantages:
One: improved the environmental problem of present domestic reinforced operation, avoided the dust injury that in the operating process, operator is caused.
Its two: the utility model silica flour feeding device is to rely on the gravity of device itself to realize feeding in raw material, and has reduced the input of manpower in reinforced process.
Three, realized concentrating reinforced, avoided in reinforced process waste and pollution to raw material.
Its four: a whole set of silica flour feeding device is simple in structure, convenient for production, installs easily, greatly reduces production cost.
Four, description of drawings
Accompanying drawing 1 is the utility model silica flour feeding device structural representation.
Accompanying drawing 2 is the utility model jacking system structure sectional view.
Accompanying drawing 3 is the utility model sealing wimble structure sectional view.
Wherein:
The 1----loading hopper, the 2----jacking system, 3----seals cone, 4----sealing vertex of a cone bar,
5---silica flour discharge port, the 6----back up pad, the 7---trim, 8----sealed bottom face,
9----bottom circular groove.
Five, embodiment
below in conjunction with drawings and Examples, the utility model is described in further detail: with reference to accompanying drawing, the utility model silica flour feeding device, it comprises loading hopper 1, sealing cone 3, jacking system 2, sealing vertex of a cone bar 4 consists of, loading hopper 1 bottom is taper, silica flour discharge port 5 is left in the bottom, sealing cone 3 is taper, sealing cone 3 is placed in loading hopper 1, the trim 7 of sealing cone 3 overlaps with loading hopper 1 sealed bottom face 8, jacking system 2 is doline, be connected with sealing vertex of a cone bar 4 on jacking system 2, sealing vertex of a cone bar 4 diameters are bored bottom circular groove 9 less than sealing, sealing cone bottom circular groove 9 diameters are identical with loading hopper 1 bottom discharge mouth 9 diameters, sealing vertex of a cone bar 4 is connected by back up pad 6 with jacking system, from three directions, sealing vertex of a cone bar 4 is fixed.Sealing cone 3 be hard sealing with loading hopper 1, and it is to realize by the gravity of loading hopper 1 self that 3 unlatching is bored in the interior sealing of loading hopper 1.Loading hopper 1, sealing cone 3, jacking system 2 one are divided into three, and be separate.When reinforced, the loading hopper that is loaded with raw material is lifted to the jacking system top by weight handling equipment, by controlling weight handling equipment, the taper bucket is fully overlapped with taper jacking system on charging opening, the taper jacking system utilizes the self gravitation of taper bucket to rise by the small-sized sealing vertex of a cone that the sealing vertex of a cone bar in jacking system will be placed in the taper bucket in this process, raw material the gap by jack-up through the charging opening filtering net and access arrangement, thereby complete reinforced process.Whole process operation is simple, and is safe and reliable.
