Abstract
The invention discloses an automatic sealing door opening and closing device of an exhaust fan. The device is arranged just on the upper side of an exhaust outlet of the exhaust fan, and mainly comprises a sealing door, a movable pin, a movable pin fixing frame and a skirt edge, wherein the movable pin is vertically and fixedly arranged in the center of the sealing door; the movable pin fixing frame is fixedly arranged on the two sides of the exhaust outlet; the middle part of the movable pin fixing frame is provided with a central hole which is matched with the movable pin; the skirt edge is fixedly arranged on a cambered edge of the sealing door and tilts outwards. According to the device, an opening and closing effect of the sealing door of the exhaust fan can be freely realized; the sealing door device has a simple structure and is low in manufacturing cost.
Description
Technical field
The present invention relates to a kind of hermatic door, specifically a kind of sealing door device that can automatically open or close of exhaust blower.
Background technology
Exhaust blower is usually used in the temperature, the humidity that regulate or control the equipment such as baking room.Except cooling normally or the operation of reduction humidity, equipment should accomplish sealing state as far as possible.And the air draft operation of exhaust blower is often in the middle of the work of interruption, this just require to arrange on equipment a kind of can the device of automatic open close, namely when exhaust blower works, Open-close sealing door is in opening, and when exhaust blower is out of service, Open-close sealing door is closed automatically, plays the insulation to equipment, protects desiccation.But existing exhaust blower automatic opening-closing complicated structure, cost are higher.
Summary of the invention
Order of the present invention is to provide a kind of with low cost, structure is simple, automatic open close is effective exhaust blower automatic open close sealing door device.
The present invention is achieved through the following technical solutions above-mentioned purpose:
The automatic open close sealing door device of exhaust blower, is located at directly over exhaust blower exhaust outlet, mainly comprises hermatic door, removable pin, removable pin fixed mount, shirt rim; Described removable pin is vertically fixed on the center of hermatic door; Described removable pin fixed mount is fixed on the both sides of exhaust outlet, is provided with the centre bore matched with removable pin in the middle part of removable pin fixed mount; Described shirt rim is fixed on hermatic door curved edge, and shirt rim is outward-dipping.
Preferably, described exhaust outlet edge is also provided with chimb.
Preferably, the oblique angle that leans outward, described shirt rim is 20 ° ~ 40 °.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, the present invention freely can realize the keying effect of exhaust blower hermatic door, and sealing door gear structure is simple, cheap;
2, the present invention arranges chimb and can stop in dust access arrangement at exhaust outlet edge, arranges automatic unlatching effect and exhaust effect that inclination shirt rim enhances hermatic door at hermatic door curved edge place.
Accompanying drawing explanation
Fig. 1 is the automatic open close sealing door device schematic diagram of exhaust blower of the present invention.
Detailed description of the invention
As shown in Figure 1, the automatic open close sealing door device of exhaust blower, is located at directly over exhaust blower 1 exhaust outlet 3, mainly comprises hermatic door 5, removable pin 8, removable pin fixed mount 6, shirt rim 4.The diameter of hermatic door 5 is identical with the diameter of exhaust outlet 3, removable pin 8 is vertically fixed on the center of hermatic door 5, removable pin fixed mount 6 is fixed on the both sides of exhaust outlet 3, removable pin fixed mount 6 overlaps with a diameter of exhaust outlet 3, also be provided with the centre bore 7 matched with removable pin 8 in the middle part of removable pin fixed mount 6, removable pin 8 can centrally freely move up and down in hole 7.Shirt rim 4 is fixed on hermatic door 5 curved edge, and shirt rim 4 is outward-dipping, and inclination angle is 20 ° ~ 40 °.For stoping in dust access arrangement, be also provided with chimb 2 in exhaust outlet edge.
When carrying out air draft operation, open exhaust blower switch, under the effect of outer row of wind, hermatic door 5 drives removable pin 8 to move up along the centre bore 7 of removable pin fixed mount 6, play the unlatching effect of hermatic door 5, and the choke effect of inclination shirt rim, hermatic door 5 curved edge place 4 in turn enhances automatic unlatching effect and the exhaust effect of hermatic door 5.After baking room 1 reaches proper moisture, close exhaust blower switch, due to gravity hermatic door 5 falls downward, drop to hermatic door 5 closing position at removable pin 8 and the guide effect lower seal door 5 of removable pin fixed mount 6, thus realize the closing motion of exhaust blower hermatic door 5.
