Description

Technical Field

[0001] The utility model relates to the field of upright roof insulation layer exhaust, and more specifically, to a roof insulation layer exhaust device. Background Art

[0002] The traditional roof construction method, that is, the upright roof, is generally constructed with the thermal insulation layer underneath the waterproof layer.

[0003] Commonly used insulation materials in engineering projects, such as cement expanded perlite, cement vermiculite, mineral wool and rock wool, are non-hydrophobic. If these insulation materials absorb moisture, their thermal conductivity will increase sharply. Therefore, in ordinary insulated roofs, a waterproof layer must be built on the insulation layer and a gas barrier layer must be built under the insulation layer, which increases the cost and complicates the structure.

[0004] Secondly, the waterproof material is exposed to the uppermost layer, which accelerates its aging and shortens the service life of the waterproof layer. Therefore, a protective layer should be added to the waterproof layer, which will increase additional investment.

[0005] Thirdly, for closed insulation layers, it is difficult to achieve a moisture content equivalent to that in a naturally air-dried state during construction due to factors such as weather and construction period. For example, if a steam exhaust roof is used because the insulation layer and leveling layer are difficult to dry, then the large number of steam exhaust holes on the roof will not only affect the use and appearance of the roof, but also artificially destroy the integrity of the waterproof layer. The rainproof covers on the steam exhaust holes are often easily knocked off, allowing rainwater to flow into the holes. Even if the steam exhaust ducts and holes are set according to the specifications, the waterproof layer may sometimes bubble. A fundamental problem here is the moisture content in the insulation material.

[0006] There are two methods to remove water vapor from the upright roof insulation layer. Option 1: Natural drying in the shade. This method takes a long time and cannot remove large amounts of water vapor from the roof insulation layer.

[0007] Option 2: Before waterproofing, the water vapor in the insulation layer is discharged, and then waterproofing is carried out to seal the layer. This method requires a long drying time before waterproofing, which affects the construction period, and it cannot be used in rainy weather.

[0008] Therefore, in view of the above problems, a roof insulation layer exhaust device is proposed. Utility Model Content

[0009] In order to overcome the above-mentioned defects of the prior art, the utility model provides an exhaust device for a roof insulation layer to solve the problems raised in the above-mentioned background technology.

[0010] To achieve the above-mentioned object, the present invention provides the following technical solution: an exhaust device for a roof insulation layer, comprising an exhaust blower body, an air intake bellows being provided at one end of the exhaust blower body, a centrifugal fan being provided in the air intake bellows, a fan motor being connected to one side of the centrifugal fan, an air supply connecting plate being connected to one end of the exhaust blower body away from the air intake bellows, and an air supply pipe being plugged into the air supply connecting plate;

[0011] Among them, the end of the air supply pipe away from the exhaust blower body is connected to a blast diversion block, and the side of the blast diversion block away from the air supply pipe is connected to multiple groups of telescopic bellows, and the end of the telescopic bellows away from the blast diversion block is connected to an exhaust pipe joint.

[0012] Preferably, the exhaust blower body is bullet-shaped, and the end of the exhaust blower body close to the air intake bellows is larger than the end of the air supply connecting plate, and the end of the air intake bellows away from the exhaust blower body is connected to an air intake baffle.

[0013] Preferably, a base plate is provided at the bottom of the exhaust blower body, and a limited position counterweight block is provided between the base plate and the exhaust blower body.

[0014] Preferably, a sealing gasket is provided at the connection between the air supply pipe and the air supply connecting plate, and an air duct connecting joint is connected between the air blast diverter block and the air supply pipe, and a plug-in sealing plug is provided at the connection between the air blast diverter block and the telescopic bellows.

[0015] Preferably, the exhaust pipe joint includes a sealing sleeve joint and a sealing plug joint, and the sealing sleeve joint is sleeve-connected to one end of the telescopic bellows, and the sealing plug joint is connected to the sealing sleeve joint by bending ninety degrees.

[0016] The technical effects and advantages of this utility model are:

[0017] Compared with the existing technology, this roof insulation layer exhaust device can carry away moisture in the roof insulation layer through air flow. The exhaust device structure can be connected to multiple exhaust pipes, which is more convenient for exhausting large roofs with multiple exhaust pipes. The exhaust blower body is driven by a centrifugal fan to supply air. The exhaust blower body takes in air from the air inlet bellows and blows it to the air blast diverter block from the air supply pipe of the air supply connecting plate. The airflow flows into multiple groups of telescopic bellows in the air blast diverter block, and is sent into the exhaust pipe joint from the telescopic bellows. It is then blown into each exhaust pipe of the upright roof insulation layer from each exhaust pipe joint. In the process of blowing, the air flow in the upright roof insulation layer is accelerated by the airflow, and the evaporation of water vapor is accelerated.

[0018] Compared with the prior art, the roof insulation layer exhaust device of this kind of roof insulation layer has various pipe joints that are easy to disassemble, which facilitates the movement of the exhaust equipment, and the structure of the pipes and joints is more convenient to adapt to the layout of the roof pipes. When the exhaust blower main body is in use or stored, the air supply pipe is installed or removed from the exhaust blower main body through the air supply connecting plate, and the telescopic bellows can be installed and removed from the air blower diversion block, and the telescopic bellows is connected or removed to the exhaust pipe joint through the sealing sleeve joint, and the exhaust pipe joint can be plugged into the exhaust pipe of the upright roof insulation layer through the sealing plug joint, so that the exhaust blower main body is more convenient to move and connect with various positions of the roof, and the telescopic bellows can be bent or telescoped according to the layout of the roof pipes, which is convenient to adapt to the complex pipe environment of the roof, and the bending structure of the sealing plug joint and the sealing sleeve joint is more convenient for connection with the exhaust pipe.
