Abstract
The utility model relates to an improvement of an air interchanger, which comprises a supporting seat. The utility model has the essential structure that three airflow guiding plates are arranged above the supporting seat. Each airflow guiding plate is composed of a flat circular ring plate and a truncated conical plate which is arranged in the flat circular ring plate. The top of the airflow guiding plate on the upmost end is provided with a top sealing plate. The airflow guiding plates are partitioned by supporting tubes and are fixed on the supporting seat by screw bolts through the supporting tubes. The utility model has the advantages of simple structure, convenient installation, convenient maintenance, etc.
Description
The utility model improvement of structure of signing an undertaking that relates to take a breath.
The structure of existing fixed formula ventilation tool is as follows substantially: be exactly angled inclined-plane is prolonged in the plectane of central opening upper end, and the lower end bolting, prolongation level is then prolonged portion, constitutes a plate body, such plate body is built up to be the ventilation tool again.Its major defect is as follows:
1, must process each air-flow guide plate and be fixed in stay pipe in the hole, and bearing is necessary for vertical the connection with circular frame, make its complex structure, bring a little difficulties to making,
2, the wall gradient of each air-flow guide plate is unreasonable, so the air suction is unstable, and the exhaust effect of room air is bad.
The purpose of this utility model just provides a kind of simple in structure, simple pneumatic fixed ventilation tool of mounting process
The purpose of this utility model is achieved in that the utility model comprises bearing, its structural feature is that the top of bearing is provided with three air-flow guide plates, the air-flow guide plate is made up of flat circle ring flat-plate and interior frustum of a cone plate thereof, air-flow guide plate top topmost has the plate of binding, be to be separated by stay pipe between the air-flow guide plate, bolt is fixed in the air-flow guide plate on the bearing by stay pipe.
Major advantage of the present utility model:
1, simple in structure:
The utility model bearing, air-flow guide plate mainly simple by body, that be easy to make are formed, and it is simple in structure, be easy to making;
2, installation, maintenance is convenient:
The utility model mainly is by bolt the air-flow guide plate to be fixed on the bearing, can be convenient to install, dismantle maintenance, provides convenience for the user uses.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a decomposition texture schematic diagram of the present utility model;
Fig. 3 is to use view;
Below in conjunction with accompanying drawing concrete structure of the present utility model is described further:
The utility model comprises bearing 1, the top of bearing 1 is provided with three air-flow guide plates 4, air-flow guide plate 4 is made up of flat circle ring flat-plate 7 and interior frustum of a cone plate 8 thereof, air-flow guide plate 4 tops topmost have the plate of binding 10, be to be separated by stay pipe 5 between the air-flow guide plate 4, bolt 11 is fixed in air-flow guide plate 4 on the bearing 1 by stay pipe 5.
For strengthening the rigidity of air-flow guide plate 4, be provided with reinforcement 6 between flat circle ring flat-plate 7 and the frustum of a cone plate 8.
The height of frustum of a cone plate 8 is preferably 7 centimetres; Angle is preferably 125 ° between the frustum of a cone plate 8 isoplanar Circular Plate 7.
During use, air-flow guide plate 4 is superimposed on the bearing 1, by bolt 11 pass spring pad 9 on the air-flow guide plate 4, stay pipe 5 with the spring pad on the gripper shoe 2 12, nut 3 link to each other.Between air-flow guide plate 4, just formed the air duct 13 of air-flow like this, indoor air just can high efficiency delivery chamber outside.
