Abstract
The utility model discloses a blast cap of an exhaust air stack. The blast cap is characterized in that a blast cap body (1) is arranged on the pipe of the vertical exhaust air stack; a middle convex joint (2) taking an annular shape of the air stack and protruding outwards is arranged on the blast cap body (1); a water cone bucket (3) is mounted in the middle convex joint (2); and the opening of the water cone bucket (3) faces upwards and the top faces downwards. The blast cap can effectively solve the technical problems of the common umbrella-shaped blast cap mounted on factories needing ventilation and chimneys, such as poor ventilation and poor rainproof effect, and can effectively obviate environment pollution caused by poor ventilation. The blast cap has the advantages of low cost, easy maintenance and long service life.
Description
Technical field
The utility model belongs to the technical field of building or structures air discharge structure, and specifically, the utility model relates to a kind of air draft chimney blast cap.
Background technology
At present, blast cap generally all is installed, is mainly played effect windproof and that keep off the rain at the air draft chimney of painting dressing automobiles industry and mill construction.The quality of blast cap directly has influence on the ventilation rainproof effect of factory and building, but present employed blast cap is generally umbellate form, this blast cap in use because the crown umbrella-shaped structure has had a strong impact on the smoothness of exhaust, causes the bad and rainproof poor effect of factory and building interior vented exhaust.Some have the gas of peculiar smell owing to be subjected to umbrella-shaped structure and hinder, and suppress down the surrounding enviroment that can not high altitude discharge have had a strong impact on factory and building at blast.
The utility model content
Problem to be solved in the utility model provides a kind of air draft chimney blast cap, its objective is problems such as the vented exhaust that solves prior art is bad, rainproof poor effect.
To achieve these goals, the technical scheme taked of the utility model is:
This air draft chimney blast cap provided by the present invention, its blast cap main body is located on the pipeline of vertical air draft chimney, protruding joint in the middle of on described blast cap main body, establishing, it is shaped as the chimney annular water receiving awl bucket is installed in the protruding joint in the described centre of outer lug, described water receiving awl bucket opening up, the vertex of a cone is downward.
For making the utility model more perfect, more detailed and concrete technical scheme below also further having proposed, to obtain best technique effect, realize goal of the invention better, and improve novelty of the present utility model and creativeness:
Vertex of a cone place at described water receiving awl bucket establishes drainpipe, and the vertex of a cone place of described water receiving awl bucket establishes through hole, and with the drainpipe pipeline connection.
Described drainpipe is tilted to down extension from the vertex of a cone of described water receiving awl bucket, and extends outside the tube wall of air draft chimney.
Caliber in the middle of described air draft chimney is positioned on the protruding joint is less than the diameter of described water receiving awl bucket upper opening.
The utility model adopts technique scheme, can effectively solve the scheme that common umbellate form blast cap is installed and have technical problems such as vented exhaust is bad, rainproof poor effect on needs take to carry out the chimney of the factory of vented exhaust and building, can effectively avoid because of the not smooth problem of environmental pollution that produces of vented exhaust, and have cheap, be easy to safeguard characteristics such as long service life.
Description of drawings
Below expressed content of each width of cloth accompanying drawing of this specification and the mark among the figure are briefly explained:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of structure shown in Figure 1.
Be labeled as among the figure:
1, blast cap main body, 2, middle protruding joint, 3, water receiving awl bucket, 4, drainpipe.
The specific embodiment
Contrast accompanying drawing below, by description to embodiment, to effect and operation principle, the manufacturing process of the mutual alignment between the shape of the specific embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and manipulate method etc., be described in further detail, inventive concept of the present utility model, technical scheme had more complete, accurate and deep understanding to help those skilled in the art.
As the expressed structure of the present utility model of Fig. 1, Fig. 2 is a kind of air draft chimney blast cap, and its blast cap main body 1 is located on the pipeline of vertical air draft chimney.
In order to solve the problem that exists at the described present known technology of this specification background technology part and to overcome its defective, realize that vented exhaust is smooth and easy, the goal of the invention of the rainproof effect of raising, the technical scheme that the utility model is taked is:
As depicted in figs. 1 and 2, this air draft chimney blast cap provided by the present invention, protruding joint 2 in the middle of on described blast cap main body 1, establishing, it is shaped as the chimney annular water receiving awl bucket 3 is installed in the protruding joint 2 in the described centre of outer lug, described water receiving awl bucket 3 opening up, the vertex of a cone is downward.
The principle of technical scheme that the utility model provides is: the air-flow in the vented exhaust chimney discharges water receiving awl bucket 3 bottoms in the protruding joint 2 in centre that arrives blast cap from lower to upper, in tapered shunting action lower edge conical surface discharging, because middle protruding joint 2 is more than 2 times of 3 calibers of water receiving awl bucket, shunting has guaranteed the smooth and easy of air motion.Water receiving awl bucket 3 rainwater that will enter chimney of back taper structure are caught and are discharged smoothly by drainpipe 4.
The utility model adopts the advantage of technique scheme to be: can effectively solve at needs and take chimney to carry out in the scheme of the common blast cap of installation umbellate form of the factory of vented exhaust and building, there are technical problems such as vented exhaust is bad, rainproof poor effect, can effectively avoid because of the not smooth problem of environmental pollution that produces of vented exhaust, and have cheap, be easy to safeguard characteristics such as long service life.
Be the concrete exemplifying embodiment that the utility model provides below, for those skilled in the art's reference and selecting for use when implementing the utility model:
Embodiment one:
Vertex of a cone place at described water receiving awl bucket 3 establishes drainpipe 4, and the vertex of a cone place of described water receiving awl bucket 3 establishes through hole, and with drainpipe 4 pipeline connections.
Drainpipe 4 is used to discharge water receiving awl bucket 3 rainwater that is compiled and sewage, effective than common blast cap, and rainwater and sewage trickle no longer everywhere.
Embodiment two:
Drainpipe 4 described in the utility model is tilted to down extension from the vertex of a cone of described water receiving awl bucket 3, and extends outside the tube wall of air draft chimney.
Said structure can reduce drainpipe resistance to gas in the air draft chimney.
Embodiment three:
Caliber in the middle of air draft chimney described in the utility model is positioned on the protruding joint 2 is less than the diameter of described water receiving awl bucket 3 upper openings.
The purpose of this structure is all to flow in the water receiving awl bucket 3 in order to ensure rainwater or sewage, can not cause rainwater and sewage to trickle in the air draft chimney.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or design of the present utility model and technical scheme are directly applied to other occasion without improving, all within protection domain of the present utility model.
