Abstract
The utility model relates to a plate type steam heating vacuum drying cabinet which is characterized in that more than one piece of hollow sheets is arranged in the case as heating elements; the hollow sheets are connected with the interlayer of the case through communicating pipes; the bottom of the case is provided with a low-temperature water vapor generator. The drying box of the utility model has the advantages of reasonable structure, large material heating area, material saving, high drying efficiency, reliable and stable quality for drying thermosensitive products, whose unit area is 2-3 times as large as the normal coil tube type oven. The utility model is an ideal device for updating old drying boxes of each research unit and producing enterprise.
Description
The utility model relates to a kind of board-like Steam Heating vacuum drying chamber, belongs to technical field of heat exchange, is applicable to the drying that has thermal sensitivity or be not suitable in air dielectric and need strict medicine that prevent to be subjected to outside contamination and chemicals etc.
At present, conventional vacuum for industrial use drying box adopts and is with charging tray that line contacts that coil pipe heats or away from the external jacket mode of heating of wet feed, the heating surface (area) (HS that provides is little and be heated inhomogeneous.The most employing of heating source is higher than 100 ℃ saturated vapor, is easy to produce hot-spot and influences product quality for the material of thermal sensitivity.Also have because of heat sensitive material need adopt and be lower than 100 ℃ of hot water heating, but its heating system must will be provided with hot water storgae and pumping equipment and be complicated, especially because it is the sensible heat that utilizes water, circulating hot water is imported and exported and is had temperature difference, the rate of drying in hot water inlet and exit is made a world of difference, thereby influence the efficient of whole drying box, the unreasonable efficient that causes of traditional drying box structure is low, arid cycle is long, defectives such as unstable product quality.
The purpose of this utility model provide a kind of can with 40 ℃～140 ℃ saturated vapor heating, unit volume and dischargeable capacitys greatly, compact conformation, high efficiency Steam Heating vacuum drying chamber.
The technical solution of the utility model is that it is made up of bearing, door, charging tray, interface, communicating pipe, casing, inner bag, heat-insulation layer, heating element heater etc., be characterised in that, hollow thin plate more than one is set as heating element heater in the casing, hollow thin plate is connected by communicating pipe with the casing interlayer, and bottom half is provided with the water at low temperature steam generator.
The utility model embodiment is described further in conjunction with the accompanying drawings.
As shown in figure 12, the board-like Steam Heating vacuum drying chamber of the utility model is by bearing 1, door 2, hollow thin plate 3, charging tray 4, vacuum interface 5 and 11, communicating pipe 6, casing 7, heat-insulation layer 8, stainless steel inner container 9, Low Temperature Steam generator 10 compositions such as grade, hollow thin plate 3 more than one is set as heating element heater in the casing 7, what of the dry thing of need are the number of plies of hollow thin plate 3 can determine according to, hollow thin plate is connected by communicating pipe 6 with the casing interlayer, hollow thin plate spacing can be made into removable adjustable or fixed, select according to user's request, as seen from Figure 3, adopt between fixed communicating pipe and the hollow thin plate and be welded to connect, on, lower box is by working hole 16 and cover plate 13, set bolt 12, sealant 17 compositions such as grade, seal communicating pipe and case shell interlayer by O RunddichtringO 14, be provided with bellow 15 between communicating pipe and the casing, absorb the thermal expansion distortion that causes because of difference variation.
Shown in Figure 4 is removable adjustable communicating pipe structure, connects hollow thin plate 3 by the left and right screw thread at tube connector 18 two, and its length depends on required hollow thin plate spacing.
The utility model working condition is described below, after 10 work of Low Temperature Steam generator, water at low temperature steam promptly feeds casing wall hollow interlayer inside configuration, arrive the hollow thin plate of multilayer 3 inside through communicating pipe 6 again, the Controllable Temperature of its water at low temperature steam is built in 40 ℃～100 ℃, and steam condensate (SC) returns Low Temperature Steam generator 10 by communicating pipe 6, for no heat sensitive material drying, the water at low temperature steam generator is not set at the bottom of drying box, and directly makes thermal source with the saturated vapor that is higher than 100 ℃.
Owing to adopted the hollow flat board of thin type to make heating element heater, the drying box casing is the hollow interlayer structure, cause that institute takes up space few to the material heating surface (area) (HS is big, the condition of placing more charging trays is provided, heating plate is a plane again, can be close to charging tray 4 base plane, help the heat transferred wet stock, quicken dry materials speed, again because be to adopt the saturated vapor that is lower than 100 ℃ to make thermal source, under the same vapor (steam) temperature condition in casing each point place, the temperature difference problem that occurs when not having the hot water heating, the steam condensation is heated to be for hot heat-transfer effect far beyond hot water, and heating system is simply compact, noiselessness and vibration.
The utility model drying box is rational in infrastructure, and unit are is bigger 1～2 times than conventional coiled baking oven, economize with material, and the drying efficiency height, reliable to dry its steady quality of thermal sensitivity product especially, be the ideal equipment that each R﹠D institution and manufacturing enterprise upgrade outmoded drying box.
