Abstract
The utility model discloses a positive-pressure silicon powder delivering device, which is characterized by comprising a silicon powder cabin (1), a silicon powder dispatching tank (2) and a silicon powder collecting hopper (3), wherein the silicon powder cabin is arranged above the silicon powder dispatching tank (2) by a discharging tube (12) and a feeding valve (13), an air inlet valve (22), which is connected with a compressed nitrogen tank, is arranged at the upper part of the silicon powder dispatching tank (2), and the silicon powder dispatching tank (2) is connected with the silicon powder collecting hopper (3) by a main delivering pipeline (4) and a discharging valve (24). The positive-pressure silicon powder delivering device adopts compressed nitrogen as delivering power, so that the surface of nitrogen powder can be prevented from being oxidized so as to keep the excellent activity of the nitrogen powder, and the safety in gas force delivering process can be ensured. By adopting the delivering device to conduct the positive pressure delivery, the delivering speed is high, the efficiency is high, the abrasion on the delivering pipeline is small, and the time for halt and maintenance is reduced, thereby improving the production efficiency.
Description
Technical field
The utility model relates to the silica flour transportation device, particularly a kind of silica flour malleation feedway.
Background technology
The polysilicon production capacity maximum in the world that the improvement Siemens process is produced accounts for 80% of aggregated capacity.This technology is with hydrogen chloride and industrial silica fume (thick silicon) synthesizing trichlorosilane at high temperature, then trichlorosilane is carried out chemical refining and purifies, and the trichlorosilane after the purification carries out chemical vapour deposition reaction and generates high-purity polycrystalline silicon in reduction furnace.At the trichlorosilane synthesis phase, the raw material silica flour is discharged into the silica flour recovering hopper through allocation and transportation, and this manually-operated mode of production efficient is low.
In recent years, some chemical plant begin to adopt the negative pressure of vacuum conveying technology to carry silica flour, but negative pressure of vacuum is carried and is had shortcomings such as delivery speed is slow, the time is long, efficient is low, and this mode is bigger to the wearing and tearing of delivery duct, often need to stop work and change or maintenance, therefore influence plant produced efficient.
The utility model content
Technical problem to be solved in the utility model provides a kind of silica flour malleation feedway, uses this silica flour feedway transportation silica flour, the wearing and tearing of material are lowered, and transport efficiency is higher.
The technical scheme in the invention for solving the above technical problem is: a kind of silica flour malleation feedway comprises that bonded assembly silica flour storehouse, silica flour send jar and silica flour recovering hopper successively; Described silica flour storehouse is arranged on the top that silica flour sends jar by discharge nozzle and inlet valve; Described silica flour sends jar top and is provided with and the tank connected air inlet valve of compressed nitrogen, and described silica flour sends jar and is connected with the silica flour recovering hopper with bleeder valve by main delivery pipe.
Described silica flour storehouse and silica flour send between the jar and are provided with weighing system.
Described silica flour storehouse is provided with dump valve.
The bottom that described silica flour sends jar is provided with and main delivery pipe bonded assembly elbow.
Described elbow is cast stone elbow or wear-resistant ceramic elbow.
Described main delivery pipe is seamless heavy wall carbon steel pipe.
Be connected with the silica flour recovering hopper more than 1 on the described main delivery pipe.
In sum, the utility model compared with prior art has following advantage:
(1), the utility model is provided with silica flour and sends jar, silica flour is sent in the jar at silica flour fully to be mixed with nitrogen, utilize pipeline to carry in compound by pressure again, as long as guarantee certain flow velocity, material can not deposit in a large number in pipeline and cause plugging, system just can move continuously, so the transport efficiency height.
(2), because the oxidisability of silicon is stronger, explosive in air when being in the powder attitude, so the utility model adopts compressed nitrogen as transmitting power, both can avoid silicon powder surface oxidized, keeps its good activity; Can guarantee the safety in the process of pneumatic transmission again.In addition, nitrogen can directly utilize the system nitrogen station in the factory to provide.
(3), material is when the elbow, several application forces in being subjected to straight length, also is subjected to action of centrifugal force, so position the most easy to wear during elbow, the utility model is selected cast stone elbow or wear-resistant ceramic elbow for use, can prolong its wearing in period.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1.
Fig. 2 is the structural representation of the utility model embodiment 2.
Fig. 3 is the structural representation of the utility model embodiment 3.
The corresponding name of each parts is called among the figure: 1-silica flour storehouse; The 11-dump valve; The 12-discharge nozzle; The 13-inlet valve; The 2-silica flour sends jar; The 22-air inlet valve; The 23-elbow; The 24-bleeder valve; The 3-recovering hopper; The 4-main delivery pipe; The 41-control cock; The 5-weighing system.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
As shown in Figure 1, a kind of silica flour malleation feedway comprises that bonded assembly silica flour storehouse 1, silica flour send jar 2 and silica flour recovering hopper 3 successively; Described silica flour storehouse 1 is arranged on the top that silica flour sends jar by discharge nozzle 12 and inlet valve 13; Described silica flour sends jar top and is provided with and the tank connected air inlet valve 22 of compressed nitrogen, and described silica flour sends jar and is connected with silica flour recovering hopper 3 with bleeder valve 24 by main delivery pipe 4.
During work, open inlet valve 13, the silica flour that the silica flour storehouse is 1 li falls into silica flour by action of gravity by discharge nozzle 12 and sends jar 2; Open air inlet valve 22, nitrogen is entered with silica flour fully mix, quicken, silica flour is transported in the recovering hopper by pressure reduction.
Described silica flour storehouse is provided with dump valve 11.
Direction when sending transmission in order to change silica flour can be provided with and main delivery pipe bonded assembly elbow 23 in the bottom of described silica flour transmission jar.
Because silica flour also is subjected to action of centrifugal force through elbow the time, the part silica flour will clash into repeatedly usually and could pass through elbow by change of direction, therefore the abrasion factor of elbow is higher, for reducing the wearing and tearing of elbow, so described elbow 23 is set to cast stone elbow or wear-resistant ceramic elbow.
Described main delivery pipe 4 is seamless heavy wall carbon steel pipe.Between main delivery pipe 4 and the recovering hopper 3 control cock 41 can also be set.
As shown in Figure 2, present embodiment is identical with embodiment 1 basic structure, and its difference only is that described silica flour storehouse and silica flour send between the jar and be provided with weighing system 5.By the setting of weighing system, silica flour is measured before conveying, be convenient to control the operational throughput of silica flour.
As shown in Figure 3, present embodiment is identical with embodiment 1 basic structure, and its difference only is, is connected with the silica flour recovering hopper 3 more than 1 on the described main delivery pipe.
As mentioned above, just can realize the utility model preferably.
