Description
Technical field
The utility model relates to stack rain shield, specifically a kind of double cone shape stack rain shield.
Background technology
The effect of stack rain shield prevents rainwater from falling into chimney by throat, affects smoke discharging effect, causes the device damage such as inner wall of stack corrosion and air-introduced machine.Existing stack rain shield mostly is " straw hat formula " rainhat, cap body is downward opening taper cone barrel, when flue gas is discharged from throat, run into " straw hat formula " rainhat of top, flow of flue gas is obstructed, flue gas is caused to arrange under cap body inwall direction, the flue gas of lower row discharged to factory building roof, then along with the reduction of flue gas flow rate, slowly to flying away in the air, cause exhaustion smoke height to reduce, exacerbate environmental pollution.In addition, when running into that the rainy day, wind was large, rainwater run-off the straight, can cause rainwater to enter chimney from the side, causes the corrosion of inner wall of stack and the damage of air-introduced machine.
Documents CN203383476 U discloses a kind of Rainproof hat for exhaust duct, comprises the rainhat top of cooperation, rainhat bottom, and rainhat top and rainhat bottom are the cone cylinder cooperatively interacted, and rainhat upper buckle is combined on rainhat bottom; And support portion is welded in rainhat, water-collecting tray is provided with in rainhat, the drainpipe led to outside rainhat is provided with bottom water-collecting tray, be connected with drainpipe by elbow bottom water-collecting tray, drainpipe runs through rainhat lower part wall and reaches outside rainhat ... rainhat upper opening in documents, water-collecting tray is arranged on rainhat inside, and during the rainy day, a large amount of rainwater falls into water-collecting tray by opening, be easy to cause rainwater to overflow from water-collecting tray, affect rainproof effect; Water-collecting tray is arranged on rainhat inside, causes rainhat not easily to make; In addition, rainhat inner structure is complicated, affects the discharge of flue gas.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides the double cone shape stack rain shield that a kind of structure is simple, smoke discharging effect good, rainproof effect is good.
Technical problem to be solved in the utility model realizes by the following technical solutions.
A kind of double cone shape stack rain shield, comprise upper cap body, lower cap body, supporting leg, the funnel that catchments, aqueduct and Convenient table, described upper cap body and lower cap body are taper cone barrel, upper cap body and the cone ports of the cone ports of upper cap body and lower cap body coaxial with lower cap body fastens, upper cap body and lower cap body are fixed together, larger than the basal diameter of lower cap body 30 ~ 40 millimeters of the basal diameter of upper cap body; One end of described supporting leg is fixed on the outside taper seat of lower cap body; The large mouth of the described funnel that catchments vertically upward and be located at the below on lower cap body circular cone top, described in the funnel that catchments be fixed on the outside taper seat of lower cap body by Convenient table, the osculum of the funnel that catchments connects an end interface of aqueduct.During installation, the other end of supporting leg is fixed on chimney; Perforate on chimney wall, passes hole and protruding about 30 centimetres by the other end of aqueduct, the junction seal welding of hole and aqueduct is fixed.Adopt the technical program, because of upper cap body basal diameter more bigger than lower cap body basal diameter (30 ~ 40 millimeters), so flue gas is discharged at a certain angle obliquely upward along the external wall of lower cap, under flue gas can not be caused, arrange phenomenon, less on the impact of exhaustion smoke height; Rainy day, time calm, rainwater vertically fell, and flows down, do not enter chimney along upper cap body; When running into that the rainy day, wind was large, major part rainwater flows down along upper cap body, does not enter chimney, and the rainwater tilted on a small quantity is pooled to along lower cap body and catchments in funnel, discharge chimney through conduit, decrease the damage of inner wall of stack corrosion and the equipment such as air-introduced machine caused because rainwater enters chimney.
As preferably, described upper cap body and lower cap body are fixed together by continuous welding at fastening place.Adopt the technical program, upper cap body and the fixation of lower cap body, and ensure that upper cap body and lower cap body fastening place do not have gap, avoid rainwater enter cap body taper cone barrel and corrode cap body inwall.
As preferably, lifting when conveniently rainhat is installed or changed, is provided with lifting nose in the upper end of described upper cap body.
As preferably, in order to prevent thunderbolt, be provided with lightning rod in the cone tip of described upper cap body.
As preferably, the quantity of described supporting leg is three, is distributed on the circumferentially same of the external wall of described lower cap.Adopt the technical program, three supporting legs enough support the weight of rainhat.Angle steel can be selected as supporting leg.
As preferably, one end of described Convenient table is welded on the outside taper seat of lower cap body, and the other end is welded on the great Kou edge of the funnel that catchments, and the quantity of described Convenient table is three, is distributed on the circumferentially same of the external wall of described lower cap.The technical program provides one and simply to catchment funnel fixed form, and diameter can be selected to be that the round steel of 10 millimeters is as Convenient table.
As preferably, an end interface of described aqueduct is linked together by the osculum of continuous welding with the funnel that catchments.Adopt the technical program, ensure that the sealing of catchment funnel and aqueduct junction, avoid junction to leak and cause the damage of the equipment such as air-introduced machine.
As preferably, in order to prevent corrosion, scribble iron oxide red anticorrosive paint on the surface of circular cone rainhat.Iron oxide red anticorrosive paint adhesive force is good, and rustless property is high, and resistance to water is strong, and natural drying is fast at normal temperatures.
