Description

Hot plate book page type turnover Wood Vacuum Drying Plant

Technical field

The invention belongs to timber dryer, further is a kind of hot plate Wood Vacuum Drying Plant.

Background technology

Existing hot plate Wood Vacuum Drying Plant adopts the direct way of contact of heating plate (oil, hot water, vapor recycle or electrical heating) to carry out timber stoving, heat output is big, rate of drying is fast, control mode is simple, quality is good, add and to utilize negative pressure of vacuum that desiccated wood is evenly exerted pressure, further improved heat transfer conditions, the various buckling deformations of timber in dry run have been avoided, reduce drying loss, in production practices, obtained abundant affirmation.But owing to will use the multilayer heating plate, the also corresponding problem of bringing the equipment operation, need lay heating plate from the top from level to level during the timber handling operation, when dress material amount is big, the size of heating plate and weight just will exceed the manpower scope, need to adopt mechanical system to lift from level to level, the equipment complicated operation, operation is loaded down with trivial details, has limited the loadings of timber, and operating efficiency is lower; When drawing off timber in addition, need place heating plate separately, because every layer of heating plate all has flexible pipe to be connected with house steward, limit the working range of handling operation, heating plate often can only be close to the drying machine placement, is easy to cause the damage of heating plate.

Summary of the invention

The purpose of this invention is to provide a kind of easy to operately, operation is simple, the high efficiency and the hot plate book page type turnover Wood Vacuum Drying Plant of fragile heating plate not.

Technical solution of the present invention is: it is propped up support, roller shutter storing top board, sealing roll curtain, plate-type condenser, condenser water inlet pipe and water outlet pipe, hot water circuit house steward, discharge outlet, vacuum exhaust pipe and is connected flexible pipe by left plate, right plate, base plate, heating plate, left fixed support, right fixed support, stay hook, support framework, heating plate and forms, left plate, right plate are plate body, and the vertical both sides that are installed in base plate; Being installed on left plate, the right plate of left side fixed support, right fixed support symmetry is respectively equipped with stay hook on it; Support framework is for being equipped with the rhabodoid that heating plate props up support on it, on the parallel base plate that is arranged between the fixed support of corresponding both sides; Be provided with hot water circuit house steward, plate-type condenser, condenser water inlet pipe and water outlet pipe, vacuum exhaust pipe, discharge outlet in the space between the support framework, wherein hot water circuit house steward, condenser water inlet pipe and water outlet pipe, vacuum exhaust pipe pass side plate respectively and link to each other with external equipment, and discharge outlet is passed base plate and communicated with the external world; It is the tabular body that roller shutter is put top board, is horizontally set on the top of support framework; Sealing roll curtain is soft airtight sheet material, puts on the top board on one side it is horizontally fixed on roller shutter, and three limits can freely be extended in addition; Horizontal positioned has the polylith heating plate in the zone that base plate, left plate, right plate and support framework surrounded, heating plate is a hollow slab, similar with heating sheet structure, every heating plate links to each other with the hot water circuit house steward by connecting flexible pipe, and a long end is placed on corresponding heating plate and props up on the support, and another long end can prop up support for axially upward freely turning down by this heating plate.

The present invention adopts leaf type turnover mode to lay heating plate, opening is big, and the scope of operation is big, utilizes the stay hook on the fixed support of both sides to fix after digging, simple and reliable for structure, can not cause the damage of heating plate again, heating plate one end is dug the preferred range that operation is in the manpower operation by a support supporting, can finish by manpower, operation is simple, and is easy to operate, improved work efficiency greatly; And, cooperate the sealing roll curtain that extends to the side from the top, form the negative pressure of vacuum environment, timber and heating plate uniform-compression that layering is successively stacked have been given full play to the advantage of hot plate type vacuum drying of wood mode.In this structure, constituted an equipment gallery between the support framework simultaneously, can concentrate equipment such as hot water circuit house steward, plate-type condenser, condenser water inlet pipe and water outlet pipe, discharge outlet are set in this space, connection and reasonable arrangement is easy.
