Abstract
The utility model relates to an air exhaust ventilation pipe for house, belonging to prefabricated component in building. The air exhaust ventilation pipe comprises a main ventilation pipe 1 and an air incoming pipe 3, wherein, a pipe interlayer 2 is arranged between the main ventilation pipe 1 and the air incoming pipe 3. The utility model is characterized in that the air incoming pipe 3 is internally provided with an abnormal shape air collecting chamber. The inlet end of the abnormal shape air collecting chamber has a connection tube 7 internally containing a non-return plate 6. And the outlet end of the abnormal shape air collecting chamber is communicated with the main ventilation pipe 1, meanwhile, an oil collecting device is arranged in the air incoming pipe 3. The utility model characterized by novel design and simple structure adopts cement and steel wire netting to make pipes, and the end and head of twin-hole non-return exhaust ventilation pipe in each layer are connected so as to form a combined air exhaust ventilation pipe for high house, so that waste gas and fume are exhausted into air to solve the problem of pollution in cities. In particular, the pipe is internally provided with a non-return plate and an abnormal shape air collecting chamber, thus waste gas and cooking fume are limited from moving up and down in the air incoming pipe or flowing back indoors. The utility model is an ideal air exhaust ventilation pipe for house.
Description
Technical field
The utility model relates to a kind of diplopore non-return exhaust ventilation pipe, especially for the exhaust ventilation pipe of kitchen, washroom, belongs to the member that presets for building.
Background technology
At present the discharging of harmful soot gas such as carbon monoxide of kitchen smoke exhaust ventilator discharging oil smoke or washroom is all adopted the direct-discharging structure of ventilation fan, range hood etc., surrounding enviroment are directly produced pollution and harm, particularly the washroom uses gas water heater, intoxication accident often has generation, mainly be carbon monoxide emission not to the utmost, in case of against the wind, waste gas pours in down a chimney comes in and influences health of people.The smoke evacuation in the house that also has, air chimney adopt concrete flue, and this kind pipeline has solved the sub-exhaust ventilation problem in house, but construction is complicated, and it is big to take up room, and air draft is not smooth, and oil gas waste gas often pours in down a chimney and refluxes into.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned shortcoming that exists, and a kind of diplopore non-return exhaust ventilation pipe is provided.The technical program is to comprise air main and air inlet pipe, the pipeline interlayer is arranged between air main and air inlet pipe, it is characterized in that in air inlet pipe, being provided with special-shaped collection chamber, the entrance point of its special-shaped collection chamber is provided with the PVC tube connector, tube connector is provided with check plate, tube connector and indoor smoke evacuation vestlet or exhaust pipe are connected, and the port of export of special-shaped collection chamber is provided with a PVC discharge bend and communicates with air main; Make waste gas to airborne release.Be provided with an oil collecting pipe on the sidewall in air inlet pipe, its oil collecting pipe upper end communicates with special-shaped collection chamber, and the oil collecting pipe lower end is provided with one and connects oil bottle, has on the tube wall of air inlet pipe and is convenient to place the window that connects oil bottle; Be provided with layering support sheet on air main, layering support sheet is formed by prolonging point around the pipeline band iron, and twice can be carried the weight of pipeline own about connecting with expansion bolt, alleviate the bottom load.
Adopt cement and gauze wire cloth to make pipeline, the diplopore non-return exhaust ventilation pipe of each layer is end to end, form the highrise building exhaust ventilation pipe that connects up and down, waste gas, oil smoke discharge are aerial, pollute mutually between building discharging waste gas, oil smoke and the resident family and the difficult problem of municipal pollution thereby solved.The utility model modern design, simple in structure, cost is low, and is in light weight, occupies little space, and it is easy to make construction safety, particularly is provided with special-shaped collection chamber and check plate in air inlet pipe, makes waste gas or the oil smoke can play in air inlet pipe and to pour in down a chimney resident family indoor.
Description of drawings
Accompanying drawing is a structural representation of the present utility model; 1-air main wherein, 2-pipeline interlayer, the 3-air inlet pipe, 4-connects oil bottle, 5-oil collecting pipe, 6-check plate, 7-tube connector, 8-collection chamber, 9-bend pipe, 10-support sheet.
The specific embodiment
The utility model is by air main 1 and air inlet pipe 3, form by pipeline interlayer 2 between air main 1 and the air inlet pipe 3, it is characterized in that being provided with in the described air inlet pipe 3 special-shaped collection chamber 8, the entrance point of its special-shaped collection chamber 8 is provided with PVC tube connector 7, tube connector 7 is provided with check plate 6, tube connector 7 is connected with indoor smoke evacuation vestlet or exhaust pipe, and the port of export of special-shaped collection chamber 8 is provided with a PVC discharge bend 9 and communicates with air main 1; Sidewall in the described air inlet pipe 3 is provided with an oil collecting pipe 5, and its oil collecting pipe 5 upper ends communicate with special-shaped collection chamber 8, and oil collecting pipe 5 lower ends are provided with one and connect oil bottle 4, has on the tube wall of described air inlet pipe to be convenient to place the window (not drawing among the figure) that connects oil bottle 5; Described air main 1 is provided with layering support sheet 10, is used to carry the weight of pipeline own, to alleviate the bottom load.
The height of exhaust ventilation pipe is the height in every floor room, and the tube connector 7 on the air inlet pipe 3 is connected with the exhaust hood pipeline, is used for kitchen exhaust; Also can connect, be used for toilet ventilation with the washroom pipeline.The exhaust ventilation pipe joins end to end and connects, and the highrise building building stack that shape connects up and down, waste gas or oil smoke have solved a difficult problem of polluting mutually between building discharging waste gas, oil smoke and the resident family to airborne release.
