Abstract
The utility model discloses the fan trouble preparation device in a kind of dust pelletizing system, main pipeline outer wall is evenly arranged fitting seat I, fitting seat II, fitting seat III, fitting seat I, fitting seat II, fitting seat III are separately installed with air door valve I, air door valve II, air door valve III, air door valve I, air door valve II, air door valve III are structurally consistent, and above-described air door valve I comprises connecting base, airduct, blade seat; Above-described blade seat is positioned at airduct inside, and blade seat and airduct dead in line; Blade seat is provided with upper blade, Leaf, lower blade, upper blade keeps one degree of freedom to be arranged on blade seat by upper coupling shaft, Leaf keeps one degree of freedom to be arranged on blade seat by middle coupling shaft, and lower blade keeps one degree of freedom to be arranged on blade seat by lower coupling shaft.The purpose of this utility model is by evenly arranging 3 air door valves on main pipeline, and when ensureing a pipe ventilated, the air door valve of two other pipeline is automatically closed.
Description
Technical field
The utility model relates to fail-safe field, particularly relates to the fan trouble preparation device in a kind of dust pelletizing system.
Background technique
Need to arrange blower fan in lime slaker dust pelletizing system, dust is carried out collection and focuses on by the negative pressure utilizing blast to produce, and blower fan is the parts of most critical in whole dust pelletizing system.Due to the significance of blower fan in dust pelletizing system, thus need to be provided with standby fan, prevent because a Fans has gone out any problem and cause whole dust pelletizing system to quit work.Standby fan needs one-way cock to control, and prevents standby fan pipeline from leaking gas, thus needs to close backup line.Air-valve in traditional lime slaker dust pelletizing system often adopts mechanical type to lock, and does not automatically lock valve.
Model utility content
The purpose of this utility model is by evenly arranging 3 air door valves on main pipeline, and when ensureing a pipe ventilated, the air door valve of two other pipeline is automatically closed.
For realizing above technological scheme, the technical solution adopted in the utility model: the fan trouble preparation device in a kind of dust pelletizing system, it is characterized in that main pipeline (9) outer wall has been evenly arranged fitting seat I (8), fitting seat II (81), fitting seat III (82), fitting seat I (8), fitting seat II (81), fitting seat III (82) is separately installed with air door valve I (7), air door valve II (71), air door valve III (72), air door valve I (7), air door valve II (71), air door valve III (72) is structurally consistent, above-described air door valve I (7) comprises connecting base (6), airduct (5), blade seat (1), it is inner that above-described blade seat (1) is positioned at airduct (5), and blade seat (1) and airduct (5) dead in line, blade seat (1) is provided with upper blade (2), Leaf (3), lower blade (4), upper blade (2) keeps one degree of freedom to be arranged on blade seat (1) by upper coupling shaft (21), Leaf (3) keeps one degree of freedom to be arranged on blade seat (1) by middle coupling shaft (31), and lower blade (4) keeps one degree of freedom to be arranged on blade seat (1) by lower coupling shaft (41).
The beneficial effects of the utility model: owing to main pipeline outer wall being evenly arranged 3 fitting seats, fitting seat is respectively arranged with air door valve, because air door valve is unidirectional air door valve, due to the existence of unidirectional air door valve, when a duct ventilation, two other airduct is closed automatically, effectively prevents standby fan pipeline to leak gas.After adopting this device, can stop to cause the out-of-work situation of whole dust pelletizing system to occur because a Fans has gone out any problem.

Embodiment
As Figure 1-3, assembling contact relation of the present utility model: the fan trouble preparation device in a kind of dust pelletizing system, main pipeline 9 outer wall is evenly arranged fitting seat I 8, fitting seat II 81, fitting seat III 82, fitting seat I 8, fitting seat II 81, fitting seat III 82 are separately installed with air door valve I 7, air door valve II 71, air door valve III 72, air door valve I 7, air door valve II 71, air door valve III 72 are structurally consistent, and above-described air door valve I 7 comprises connecting base 6, airduct 5, blade seat 1; It is inner that above-described blade seat 1 is positioned at airduct 5, and blade seat 1 and airduct 5 dead in line; Blade seat 1 is provided with upper blade 2, Leaf 3, lower blade 4, upper blade 2 keeps one degree of freedom to be arranged on blade seat 1 by upper coupling shaft 21, Leaf 3 keeps one degree of freedom to be arranged on blade seat 1 by middle coupling shaft 31, and lower blade 4 keeps one degree of freedom to be arranged on blade seat 1 by lower coupling shaft 41.
Working principle of the present utility model: as shown in Figure 4, when wind direction is to blowing up, upper blade 2, Leaf 3, lower blade 4 are all in closed condition.As shown in Figure 5, when wind direction is to blowing down, upper blade 2, Leaf 3, lower blade 4 are all in opening state.Fig. 6 selects the blade in air door valve I 7 to be open working state, and air door valve II 71 is in closedown off working state with the blade of air door valve III 72, realizes wind direction and carries towards main pipeline 9 axial direction.
Apply specific case herein to set forth principle of the present utility model and mode of execution, the explanation of above example just understands method of the present utility model and core concept thereof for helping.The above is only preferred implementation of the present utility model, should be understood that, due to the finiteness of literal expression, and objectively there is unlimited concrete structure, for those skilled in the art, under the prerequisite not departing from the utility model principle, some improvement, retouching or change can also be made, also above-mentioned technical characteristics can be combined by rights; These improve retouching, change or combination, or the design of model utility and technological scheme are directly applied to other occasion without improving, and all should be considered as protection domain of the present utility model.
