（Three）Beneficial effect
The utility model provides a kind of pneumatic rain cap.Possesses following beneficial effect：
The utility model is by setting drainage blower fan, airduct, limited block, rotating shaft, Yu Gai, balancing weight and baffle plate so that
When cyclone dust collectors periodic maintenance cannot be operated, drainage blower fan is operated, and sprays upward in exhaust chimney by airduct
Air-flow, by frictional force drive around flue gas move upwardly together, wash rain lid open, make rain lid around rotating shaft Unscrew, when
When cyclone dust collectors need not be repaired, drainage blower fan is closed, rain lid is closed under gravity, and flue gas is by mistake in cyclone dust collectors
Discharged after filter, so as to reach pneumatic unlatching, the effect voluntarily closed is cheaper in contrast to traditional electric butterfly valve, and therefore
Barrier is relatively low.
Brief description of the drawings
Fig. 1 is the cross-sectional view of the utility model front view.
In figure：1 exhaust chimney, 2 chimneys, 3 cyclone dust collectors, 4 drainage blower fans, 5 airducts, 6 limited blocks, 7 rotating shafts, 8 rain
Lid, 9 balancing weights, 10 corrosion-inhibiting coatings, 11 rubber cushions, 12 baffle plates.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
As shown in figure 1, the utility model provides a kind of technical scheme：A kind of pneumatic rain cap, including exhaust chimney 1 and drainage
Blower fan 4, the inwall of exhaust chimney 1 is fixedly connected with corrosion-inhibiting coating 10, and the flue-gas temperature of discharge is general at 70-500 DEG C, relatively wet
It is 3% to spend, and ash content and various corrosive elements, such as SO2, HCL, NO2 and salt fog are contained in flue gas, therefore to inner wall of stack
Seriously corroded, can effectively extend the service life of chimney by setting corrosion-resistant coating 10, it is fixed on the side wall of exhaust chimney 1
Branch chimney 2 is connected with, the connection cyclone dust collectors 3 of branch chimney 2 include a large amount of ash contents, are discharged directly into meeting in air in flue gas
Assembly air pollution, the ash content included in flue gas can be fully absorbed by cyclone dust collectors 3, reduce pollution, drainage blower fan 4
Output end is fixedly connected with airduct 5, the external power supply of drainage blower fan 4 and controller, and the table of exhaust chimney 1 is run through in one end of airduct 5
Face simultaneously extends to the inside of exhaust chimney 1, and airduct 5 is located at one end in exhaust chimney 1 straight up, so that air-flow is vertical
Discharge upwards, has reached guiding air-flow and has moved the effect for washing rain lid 8 open upwards, and exhaust chimney 1 is fixedly connected with the top of surface
Limited block 6, limited block 6 is shaped as inverted L-shaped, and the top for controlling the anglec of rotation of rain lid 8, exhaust chimney 1 passes through
Rotating shaft 7 is flexibly connected rainy lid 8, and rain lid 8 is rotated so as to complete to open and close around rotating shaft 7, and the lower surface of rain lid 8 is fixed and connected
Rubber cushion 11 is connected to, air-tightness is ensured when can close rain lid 8 by setting rubber cushion 11, rain lid 8 is fixed away from the side of rotating shaft 7
Balancing weight 9 is connected with, the weight of balancing weight 9 is 1 kilogram, and balancing weight 9 is overweight, causes air-flow to wash rain lid 8, balancing weight 9 open
Kick the beam, cause rain lid 8 to be not closed completely, so it is optimal that balancing weight 9 selects in scope 1 kilogram or so, rain lid 8 is away from balancing weight 9
Side be fixedly connected with baffle plate 12, when rain lid 8 is rushed to open produce rotation, baffle plate 12 and limited block 6 are overlapped, so that rain lid
8 is inclined, prevents rain lid 8 vertically, and after closing drainage blower fan 4, the stress equalization of rain lid 8 or so cannot close.
When using, the flue gas produced in cremator floats under gravity, enters from the bottom of exhaust chimney 1, due to
The closure of rain lid 8 so that flue gas is poured in from the branch chimney 2 of one side, by flue gas after cyclone dust collectors 3 carry out dedusting to flue gas
Discharge, when cyclone dust collectors 3 overhaul the period, opens drainage blower fan 4, produces updraft to drive flue gas to move straight up, keeps away
Exempt from flue gas to enter in branch chimney 2, after air-flow washes rain lid 8 open, fume emission after the completion of cyclone dust collectors 3 are overhauled, closes drainage wind
Machine 4, the thrust that rain lid 8 is subject to reduces, so as to voluntarily close under gravity.
Can to sum up obtain, the utility model is by setting drainage blower fan 4, airduct 5, limited block 6, rotating shaft 7, rain lid 8, balancing weight
9 and baffle plate 12 so that when the periodic maintenance of cyclone dust collectors 3 cannot be operated, drainage blower fan 4 is operated, by airduct 5 in row
The upward air-flow of injection in Gas chimney 1, the flue gas for driving surrounding by frictional force is moved upwardly together, and washes rain lid 8 open, makes rain lid
8 around the Unscrew of rotating shaft 7, when cyclone dust collectors 3 need not be repaired, closes drainage blower fan 4, and rain is covered under 8 Action of Gravity Field
Close, flue gas is by discharge after filtering in cyclone dust collectors 3, so as to reach pneumatic unlatching, the effect voluntarily closed, in contrast to biography
The electric butterfly valve of system is cheaper, and failure is relatively low.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out various changes in the case where principle of the present utility model and spirit is not departed from, repaiies
Change, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
