Detailed Description
In order to enhance the understanding of the present invention, the following detailed description will be made in conjunction with the embodiments and the accompanying drawings. The utility model discloses the accessible is implemented as follows:
referring to fig. 1 and 2, the present invention relates to an air supply and exhaust device, which includes a blower assembly 1 and an exhaust assembly 2 fixed side by side with the blower assembly 1;
the air blowing kit 1 comprises a filter screen 11, an air blower 12 and an air supply pipe 1 positioned at the bottom of the air blowing kit 1;
the exhaust kit 2 includes an exhaust pipe 21 and a connection sleeve 22.
The blast external member 1 and the exhaust external member 2 are formed by cold rolling through a sheet metal process;
the exhaust sleeve 2 and the blowing sleeve 1 are in the same shape and share a cuboid with one side plane, wherein the filter screen 11 is installed on the blowing sleeve 1 in a covering mode on the surface which is not in contact with the exhaust sleeve 2.
A blower 12 is mounted inside the blower assembly 1, draws air through the screen 11 and supplies air to the equipment from an air supply duct 13 connected to the air inlet of the equipment.
The filter screen 11 is a ventilation filter screen made of nylon material, and is used for filtering dust and fibers in air, and ensuring that the air blower 12 extracts clean air.
The exhaust pipe 21 is connected with an exhaust port of the equipment and used for guiding the waste gas generated by the equipment to the connecting sleeve 22 to be exhausted;
the top of the connecting sleeve 22 is provided with a negative pressure exhaust pipeline for exhausting waste gas to avoid dissipation.
The air supply and exhaust device is installed on the top of the equipment cabinet, and is connected with the equipment in the equipment cabinet through an air supply pipe 13 and an exhaust pipe 21, when in operation, the air supply pipe 13 supplies external air drawn by the blower 12 to the equipment, and the exhaust pipe 21 exhausts exhaust gas generated by the equipment.
The utility model discloses a supply exhaust apparatus can include following embodiment:
the air blowing external member 1 and the exhaust external member 2 are respectively formed by two rectangular cold-rolled steel plates through sheet metal process cold rolling, wherein the formed exhaust external member 2 is a cuboid with an upper opening and a lower opening, the air blowing external member 1 shares a side plane with the exhaust external member 2, the side, which is not contacted with the shared plane, of the air blowing external member 1 is an air inlet, a filter screen 11 is installed on the air inlet in a covering mode, the bottom of the air blowing external member 1 is provided with an air supply pipe 13, and the bottom of the exhaust external member 2 is provided with an exhaust pipe 21.
