Abstract

The utility model relates to a bottom pipe for a general vertical duct for carrying waste gas away used for the tail end of a vertical duct for exhausting in concentration various gas, fumes, residual oil and water for buildings. The utility model is composed of a main duct, an auxiliary duct with an exhaust vent and a fume exhausting hole and a guide plate, wherein, a through hole is arranged between the main and the auxiliary ducts, and the tail end of the main duct is an opening which is connected with a discharging device. The head and the tail ends of the bottom pipe are separately connected with the tail end of the intermediate section of a discharging pipeline and the specific daub sealed opening wound by a strong adhesive tape of the discharging device. When in use, rain water on a roof can flow into the main duct through the discharging pipeline and finally flow into the discharging device through the main duct of the bottom pipe, and the residual oil can enter the main duct through the through hole on the auxiliary duct of the bottom pipe and then flow into an in-discharging device, having the advantages of multi-function on one pipe and good discharging effect.

Description

The bottom tube of vertical integrally discharging duct

The utility model relates to the end pipe that is used for concentrating the vertical duct that discharges various waste gas, cigarette and roofing water and Residual oil in a kind of building, the bottom tube of vertical integrally discharging duct.

In people's daily life, use which kind of fuel all can produce the carbon monoxide pernicious gas, pollute for reducing, generally all adopt at kitchen installation smoke exhaust, with smoke exhaust pipe from window or wall hole directly to the mode of outdoor discharging, thereby the cross pollution phenomenon occurs, still endanger the healthy of people.

The patent No. 94224338.2 " Residential Soot Emissions Valveless Pipes " just provides a kind of no check (non-return) valve, can prevent from again to be used in the building of flue downdraught concentrating to scavenge and vertical duct that deodorizing is ventilated.But it does not also have draining, row's Residual oil function.

The purpose of this utility model is to provide a kind of energy one tube multipurpose, can get rid of flue gas, deodorizing ventilation, can get rid of the bottom tube of the vertical integrally discharging duct of roofing water and Residual oil again.

The bottom tube that the utility model is achieved in that vertical integrally discharging duct is made up of the secondary duct and the guide plate of trunk line, band steam vent, smoke vent, and major and minor pipeline enclosure has through hole, and the end of trunk line is that opening is connected with tapping equipment.

Fig. 1. be structural representation of the present utility model.

Fig. 2. be the A-A view of Fig. 1.

Fig. 3. be the B-B view of Fig. 1.

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

Trunk line (3), secondary duct (2), guide plate (5) all by do not fire, waterproof, anti-corrosion material make.

The head end of bottom tube (8) is an openend, is made up of trunk line (3), secondary duct (2) two parts, and there is reinforced wall (1) at the edge.And the end of bottom tube (8) also is an openend, is made up of trunk line (3) separately, and also there is reinforced wall (1) at the edge.

Secondary duct (2) end is a blind end, and bottom angled becomes 60～80 ° of angles with guide plate (5), on the guide plate (5) of secondary duct (2) inclination place through hole (7) is arranged, and corresponding smoke vent (4) and steam vent (6) are all arranged on front and back two walls of secondary duct (2).Select as required to use different holes, other no hole can be stopped up.

End with the stage casing pipe of the head end of bottom tube and integrally discharging duct, the end openings end and the tapping equipment of bottom tube, the head end of stage casing pipe and the end of push pipe twine three circles with powerful adhesive tape respectively and seal with autocratic clay, connect into whole vertical integrally discharging duct, the head end of push pipe is the cover cap of fixing ventilation (figure omits) also.

Dewatering installation can be tapping pipe, spilled water hole, catch-drain, drain valve etc.

During use, the rainwater on the roof is combed through the push pipe lateral intake and is flowed into trunk line, after the trunk line in the bottom tube (3) flows into tapping equipment.And flue gas, foul smell enter secondary duct (2) through smoke vent (4), the steam vent (6) of each level of building respectively, enter trunk line (3) again, emit by the cover cap on the push pipe at last.Residual oil through hole (7) on the secondary duct (2) in bottom tube enters trunk line (3), again below ground in the tapping equipment inlet chamber.

The utility model is compared with prior art: because of the trunk line in the bottom tube by tapping equipment and atmosphere Communicate, can increase the pressure reduction of upper and lower of pipeline, produce stack effect, improve the uplift force of trunk line, Improved simultaneously discharge efficiency. Because of the trunk line distal opening, also can be simultaneously except upwards exhaust, smoke evacuation Discharging rainwater and Residual oil, one tube multipurpose can the exhaust bodies, again can discharging liquid. And the bottom tube end only has supervisor Road part, no secondary duct can reduce volume, save material.

Claims

1. the bottom tube of a vertical integrally discharging duct, bottom tube (8) is by trunk line (3), band steam vent (6), the secondary duct (2) of smoke vent (4) and guide plate (5) are formed, it is characterized in that through hole (7) is arranged between major and minor pipeline (3), (2), the end of trunk line (3) is that opening is connected with tapping equipment.
