Abstract

The utility model relates to a vertical swinging apparatus of an electric fan. A set of gear transmission mechanisms which are driven by a synchronous motor are arranged on the base of an electric fan; the axle pin of the vertical swinging base of the vertical swinging apparatus of an electric fan is provided with a torsion spring to adjust the center of gravity of a fan head. The apparatus has all the functions of an existing swinging electric fan and the function of a vertical swinging head which can be operated conveniently, and is particularly suitable for a wall fan. Simultaneously, the apparatus provides a basis for the remote control of the swinging head of an electric fan. The utility model has the advantages of simple structure, convenient operation and easy application.

Description

Vertical swinging apparatus of fan

The utility model belongs to drying equipment.

Though drying equipment such as contact drier, hot air flow dryer etc. that tradition is used are relatively simple for structure, but be difficult to wet part high, viscosity big, easily the fouling material carries out effective dry and handles, and the thermal efficiency is low, energy consumption is high, it is heavy to stir operation, and particularly the material fouling will make Dry run normally carry out.

Task of the present utility model provide a kind of be applicable to wet part high, viscosity big, the easy drying equipment of fouling material, reaches easy to operate, the thermal efficiency is high, the purpose of saving energy.

The organization plan of a kind of contact drying and flash drying hybrid type dynamic combined dryer is proposed for achieving the above object.

Accompanying drawing is a structural representation of the present utility model.

With reference to the description of drawings organization plan:

As shown in drawings, this new structure characteristics be in the shell 6 heating tube nests 4 respectively manage two ends respectively break-through and be fixed on steam admission side tube sheet 3 and exhaust region tube sheet 8 on, the Intake shaft 1 of heating tube nest and tube sheet, end socket 2,10 and hollow and exhaust shaft 9 form the rotor of an integral body, be assembled with some angle steel at rotor edge, the flight 7 of changeable angle is installed on the angle steel.Quill shaft 1 one end M enter steam and discharge from an end N of quill shaft 9 through the internal channel of respectively managing of heating tube nest 4.Air sucks in the housing from shell two ends ventilation eye, adds the thermosetting thermal air current through heating tube nest and passes from storeroom, is discharged from exhaust port C by induced draught fan again.Shell 6 is being offered material inlet A near steam inlet one upper lateral part, and material is constantly dug by flight, and discharge from the material outlet B that is opened in shell opposite side bottom dry back.

This programme advantage:

1. steam passes through in all pipes of heating tube nest, and material contacts with heating tube nest and absorbs wet part of heat of vaporization;

2. air enters from shell two ends ventilation mesh, is heated to 80～90 ℃, is extracted out by induced draught fan from exhaust port C and forms the material enforcement flash drying of hot air flow to constantly stirring.

3. rotor rotates with certain speed, and flight is constantly taken up material, causes the contact layer of bringing in constant renewal in tube bank and material, can effectively avoid the material fouling.The material that is stirred by the rotor flight constantly is pushed to outlet with material from inlet.
