Description
Technical field
The present invention relates to drying and dry industrial technology field, the especially a kind of vertical lift type drier External tilting door of straight-line single air cylinder driven handled of chemical industry of machine components Coating Pretreatment.
Background technology
Dry purpose is moisture or the solvent of removing in some raw material, the half-finished parts, and purpose is with regard to industrial, makes machine components or material be convenient to packing, transportation, storage, processing and use.In numerous drying equipments, it is to make the material that is dried do forward travel along the drier passage that a kind of equipment is arranged, and only pass through passage once, machine components or material remain static in the mechanism that transports it, the reinforced of thing that be dried carries out at the drier two ends with discharging, and this drier is called the tunnel passage type drier.As the tunnel passage type drier, its device door must be tight, and based on the device door of lift motion, non-externally swing elevating movement tends to cause friction unnecessary between device door and the drier body, and the device door is descended service life; And common externally swing lifter door adopts rotary cylinder driving or the motor form that matches with gear, tooth bar to drive more, its structure relative complex, and maintainability is poor.
Summary of the invention
The purpose of this invention is to provide a kind of vertical lift type drier External tilting door that single rectilinear motion air cylinder driven can be set in the door opening both sides of tunnel passage type drier, it is simple in structure, processes easy, easy to maintenance.
