Technical field
The utility model belongs to constructure ventilation exhaust technique field, is specifically related to a kind of building waste gas oil smoke row suction device that utilizes natural wind.
Background technology
Along with the development of urban construction, high buildings and large mansions are more and more, usually forming very strong wind zone near the high building and between the high building.In case blow, then the wind-force of wind zone is very strong, and building and safety are had bigger harm.Simultaneously, when strong wind blowed, the door and window that building facings the wind closed, to reduce wind and dust storm to indoor influence.And that door and window closes indoor ventilation is totally unfavorable, and often adopt ventilation equipment to carry out forced ventilation this moment, with the holding chamber inner air flow.When air surpasses certain humidity and temperature, just need timely ventilation in the industrial production, particularly some factory buildings, warehouse etc. seem important especially.And in the oil smoke discharge process of industrial waste gas and residential houses often because wind and rain is former thereby phenomenon occurs passing through, have a strong impact on and damage for industrial production and healthy the causing of resident.
The common outside method for exhausting of mechanical type that adopts is mainly based on electronic.The advantage of electronic exhaust plant is that capacity is big, and its shortcoming is noise to be arranged during work with electricity as power, and it is very big to clean difficulty on the exhaust plant behind laying dust or the greasy dirt, and damages easily, brings very big difficulty to regular maintenance, makes its continuous operation for a long time.Under current power situation in short supply, how research utilizes natural wind row to inhale waste gas and oil smoke, has remarkable practical significance and huge economic value.
At present, the existing multiple exhaust plant that utilizes natural wind, it turns round according to natural wind automatically with the principle of air stream drives, without power consumption, energy conservation.But its in order to solve because wind direction changes the problem that supply and exhaust brings, but exhaust opening all is designed to the structure that box haul rotates.Yet because oil smoke strong adhesion, corrosivity are big, add gathering of flue dust, can make rotatable parts to rotate with the wind very soon and lose due function, thereby lose actual use value.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the shortcoming of existing exhaust facility, provide a kind of simple in structure, cost is low, be easy to processing and manufacturing, no operating cost, no-rotary part, wind-engaging is to the building waste gas oil smoke row suction device that utilizes natural wind of influence.
Solving the problems of the technologies described above the technical scheme that is adopted is: be provided with kuppe down in smoke evacuation standpipe upper end, be processed with on the upper surface of following kuppe and the identical hole of standpipe outer shape of discharging fume, at least be provided with three root posts on the upper surface of following kuppe, the column upper end is provided with kuppe, and last kuppe lower surface is provided with discharges fume pipe.
The outer shape of down kuppe of the present utility model is the positive terrace with edge of at least four ribs, and the upper base area of following kuppe is less than going to the bottom area, the outer positive terrace with edge of at least four ribs that is shaped as of last kuppe, and the area of going to the bottom of last kuppe is less than the upper base area.
It is of the present utility model that upward the kuppe outer shape is identical with the shape of following kuppe.
Of the present utility model going up constitutes the convergent contour passage between kuppe left surface and the following kuppe left surface, constitute the divergent contour passage between last kuppe right flank and the following kuppe right flank, constitute Lavalle shape passage between last kuppe left surface and the following kuppe left surface and between last kuppe right flank and the following kuppe right flank, the upper end of exhaust standpipe is positioned at the throat of Lavalle shape passage.
The pipe of discharging fume of the present utility model is a convergence pipeline from bottom to top.
The Lavalle shape passage that the utility model has adopted last kuppe and following kuppe to form, Lavalle shape passage throat forms negative pressure, the smoke evacuation standpipe is arranged on Lavalle shape passage throat, no matter natural wind in any direction blows, generation is successfully discharged flue gas the swabbing action of flue gas in the smoke evacuation standpipe from the diffuser of Lavalle shape passage.Under calm situation, the convergent contour from bottom to top that flue gas is provided with from the last kuppe pipe of discharging fume can make the flue gas in the exhaust standpipe discharge smoothly.The utlity model has simple in structure, without exhaust fan, no-rotary part, wind-engaging can not promoted the use of at house kitchen and meal shop to the advantage of influence.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and example the utility model is further described, but the utility model is not limited to these embodiment.
Embodiment 1
In Fig. 1, the building waste gas oil smoke row who utilizes natural wind of present embodiment inhales device and is made of last kuppe 1, the pipe 2 of discharging fume, column 3, smoke evacuation standpipe 4,5 connections of following kuppe.
The smoke evacuation standpipe 4 of present embodiment is a circular pipe, be fixedly connected with the screw threads for fastening connector in smoke evacuation standpipe 4 upper ends time kuppe 5 is installed, the outer shape of following kuppe 5 is positive six terrace with edges, the upper base area of positive six terrace with edges is processed with on the upper surface of following kuppe 5 and the lower surface and discharge fume standpipe 4 outer shape and big or small identical circular port less than the area of going to the bottom.Be fixedly connected with the screw threads for fastening connector on the upper surface of following kuppe 5 four root posts 3 are installed, the height of every root post 3 is identical with smoke evacuation standpipe 4 calibers.Be fixedly connected with the screw threads for fastening connector in the upper end of four root posts 3 kuppe 1 is installed, last kuppe 1 outer shape is positive six terrace with edges, the upper base area of positive six terrace with edges is greater than the area of going to the bottom, last kuppe 1 outer shape is identical with the shape of following kuppe 5, constitute the convergent contour passage between last kuppe 1 left surface and following kuppe 5 left surfaces, constitute the divergent contour passage between last kuppe 1 right flank and following kuppe 5 right flanks, constitute Lavalle shape passage between last kuppe 1 left surface and following kuppe 5 left surfaces and between last kuppe 1 right flank and following kuppe 5 right flanks, correct the throat that is positioned at Lavalle shape passage on the smoke evacuation standpipe 4.The lower surface that the upper surface of last kuppe 1 is processed with kuppe 1 on the circular port is processed with the circular port bigger than the circular port on the upper surface, be fixedly connected to be equipped with the screw threads for fastening connector on last kuppe 1 lower surface and discharge fume pipe 2, the pipe 2 of discharging fume is from bottom to top convergence pipeline.The building waste gas oil smoke row who utilizes natural wind of this structure inhales device, and under calm situation, the waste gas oil smoke is through smoke evacuation standpipe 4, and the smoke evacuation from last kuppe 1 goes out pipe 2 discharge successfully.Having under the situation of wind, no matter natural wind in any direction blows, the leading portion of throat in the Lavalle shape passage that between last kuppe 1 and following kuppe 5, forms, air-flow velocity progressively increases, pressure progressively reduces, throat pressure minimum at Lavalle shape passage, back segment air-flow velocity at Lavalle shape passage progressively reduces, pressure progressively increases, and makes that the waste gas oil smoke in the kitchen can successfully be discharged in the Lavalle shape passage that forms between last kuppe 1 and the following kuppe 5.
