Abstract
The invention provides a double-fan air barrel with an automatic switchover device, and belongs to the technical field of machine manufacturing. The double-fan air barrel structurally comprises a barrel body, two baffles are installed at the intersection of two air inlets of the barrel body, one end of one baffle is connected with one end of the other barrel through a rotating shaft, the baffles can rotate with the rotating shaft as the center, the baffles are arranged in an intersected mode, and each baffle corresponds to one of the air inlets. The baffles are matched with the air inlets of the barrel body in size, and the rotating shaft is arranged at the intersection of the two air inlets of the barrel body. Compared with the prior art, the double-fan air barrel has the advantages of being reasonable in design, simple in structure, convenient to use and the like, the reliability and the safety of a ventilating system are guaranteed, and safety production is ensured.
Description
Technical field
The present invention relates to machinery manufacturing technology field, specifically a kind of two blower fan air ducts with automatic switching control equipment.
Background technique
When using two blower fan air ducts, need manual switching from the wind of different air ducts, so just increased staff's labor intensity; And manual operation is not prompt enough, so, just make the reliability of ventilation system and Security reduce, be unfavorable for the Security of producing.
Summary of the invention
Technical assignment of the present invention is for the deficiencies in the prior art, and a kind of reasonable in design, two blower fan air ducts with automatic switching control equipment that using effect is good are provided.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of two blower fan air ducts with automatic switching control equipment, comprise cylindrical shell, the place intersecting at two intake grills of cylindrical shell is provided with two baffle plates, one end of two baffle plates is connected together by rotating shaft, baffle plate can rotate centered by rotating shaft, arranged in a crossed manner between baffle plate, the every respectively corresponding intake grill of baffle plate; The size of baffle plate matches with cylindrical shell intake grill size, and aforementioned rotating shaft is arranged on the intersecting of two intake grills of cylindrical shell.
With two blower fan air ducts for automatic switching control equipment, its two baffle plate sizes are identical.
With two blower fan air ducts for automatic switching control equipment, two intake grills of its cylindrical shell are symmetrical arranged about spindle central.
Compared with prior art, the beneficial effect producing is two blower fan air ducts with automatic switching control equipment of the present invention:
The features such as that the present invention has is reasonable in design, simple in structure, easy to use, function admirable, practicality, the air duct that can automatically switch, solves blower fan manual switching air duct problem, has reduced staff's labor intensity, guarantee ventilation system reliability, Security, guaranteed safety in production.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention.
In figure: 1, exhaust outlet, 2, baffle plate, 4, intake grill, 5, rotating shaft, 6, cylindrical shell.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail below.
As shown in drawings, two blower fan air ducts with automatic switching control equipment of the present invention, its structure comprises cylindrical shell 6, the place intersecting at two intake grills 4 of cylindrical shell 6 is provided with the identical piece baffle plates 3 of two sizes, one end of two baffle plates 3 is connected together by rotating shaft 5, baffle plate 3 can rotate centered by rotating shaft 5, arranged in a crossed manner between baffle plate 3, the every respectively corresponding intake grill 4 of baffle plate 3; The size of baffle plate 3 matches with cylindrical shell 6 intake grill 4 sizes, and aforementioned rotating shaft 5 is arranged on the intersecting of two intake grills 4 of cylindrical shell 1; Two intake grills 4 of cylindrical shell 1 are about rotating shaft 5 Central Symmetry settings.
According to the bore of air duct, do two oval baffle plates, on baffle plate, be covered with a circle rubber cushion (preventing from leaking out), if two intake grills in cylindrical shell, form face place at grade, two baffle plates are intersected 90 ° (calculating the distance between two air ducts) does support with reinforcing bar and is fixed between two air ducts, and baffle plate is along with the wind-force from different direction automatically switches to normal air feed on another air channel.
If be less than 180 degree between the face that two intake grills form in cylindrical shell, two baffle plate intersecting angles can be set to the form of acute angle.
According to two intake grills, in cylindrical shell, form the situation of face the intersecting angle of baffle plate is set, like this when an air channel air feed, allow this air channel overhead gage be in all the time the neutral position of cylindrical shell, can keep thus the oppressive force that this air channel barrier is rotated to the opposing party, thereby allow another baffle plate remain the state of closing another air channel.
Two its processing and fabricatings of blower fan air duct with automatic switching control equipment of the present invention are simple and convenient, processing and fabricating shown in by specification accompanying drawing.
Except the technical characteristics described in specification, be those skilled in the art's known technology.
