Abstract
The utility model is suitable for a chemistry equipment field provides a vacuum drying oven, including the box and with the sealing door that the box pivot is connected, be provided with the heating chamber in the box, the internal surface in heating chamber inwards evenly is provided with a plurality of protruding, is provided with the heater strip in every protruding strip. The utility model provides a vacuum drying oven, the internal surface in its inner heating chamber set up the heater strip in every protruding strip, therefore the heater strip is at heating intracavity evenly distributed for the protruding strip structure of ripple to the heating heating area in heating chamber is bigger, makes the distribution of temperature of heating intracavity more even, has guaranteed to treat the dry substance thermally equivalent.
Description
Technical field
The utility model belongs to chemical device field, particularly relates to a kind of vacuum drying chamber.
Background technology
Vacuum drying chamber aims at dry heat sensitivity, easily decomposition and oxidizable material and designs, the vacuum that heating chamber keeps certain can be made during work, and internally can be filled with inert gas, particularly the article of some complicated components also can carry out rapid draing, adopt Intelligent Digital humidostat carry out setting, the display of temperature and control.
Current vacuum drying chamber, its inner heating chamber is made up of plane steel plate, and heater strip is positioned at bottom surface steel plate, and heating chamber inside arranges support, when specifically using, material to be dried is placed on support, after shutting hermatic door, heating chamber is vacuumized and keeps certain vacuum degree, internally can also be filled with inert gas whenever necessary, finally to heater strip energising, heating cavity temperature is made to reach preset temperature.But find during actual use, because heater strip is arranged on bottom heating chamber, temperature distributing disproportionation during heating in chamber is even, and the efficiency of heating surface is not high.
Utility model content
In view of the above problems, the purpose of this utility model is to provide a kind of vacuum drying chamber, is intended to solve existing vacuum drying chamber and heats uneven technical problem.
The utility model adopts following technical scheme:
The hermatic door that described vacuum drying chamber comprises casing and is connected with described casing rotating shaft, be provided with heating chamber in described casing, the inner surface of described heating chamber is inwardly evenly provided with some protuberant bars, is provided with heater strip in every bar protuberant bar.
Further, the cross sectional shape of described protuberant bar is rectangle.
Further, described heating chamber periphery also arranges a circle vacuum chamber.
Further, described vacuum chamber periphery also arranges a circle insulation material.
Further, described casing side is also provided with bleeding point, and described bleeding point is communicated to described heating chamber, and described bleeding point is for connecting vavuum pump.
The beneficial effects of the utility model are: the vacuum drying chamber that the utility model provides, the inner surface of its inner heating chamber is corrugation lobes bar structure, in every bar protuberant bar, heater strip is set, therefore heater strip is uniformly distributed in heating chamber, and the heating heating surface area of heating chamber is larger, make the Temperature Distribution in heating chamber more even, ensure that material thermally equivalent to be dried.
Accompanying drawing explanation
Fig. 1 is the structure chart of the vacuum drying chamber that the utility model embodiment provides.
Fig. 2 is that heating chamber A-A is to sectional view.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
In order to technical scheme described in the utility model is described, be described below by specific embodiment.
Fig. 1 shows the structure of the vacuum drying chamber that the utility model embodiment provides, and Fig. 2 shows the internal structure of heating chamber, illustrate only the part relevant to the utility model embodiment for convenience of explanation.
With reference to shown in Fig. 1, Fig. 2, the hermatic door 2 that the vacuum drying chamber that the present embodiment provides comprises casing 1 and is connected with described casing rotating shaft, heating chamber 3 is provided with in described casing 1, the inner surface of described heating chamber 3 is inwardly evenly provided with some protuberant bars 31, is provided with heater strip 32 in every bar protuberant bar.
In the present embodiment, heating chamber 3 is steel plate material, and surface is corrugation lobes strip, heater strip 32 is uniformly distributed at the inner surface of heating chamber, and be arranged in protuberant bar 31, the cross sectional shape of described protuberant bar 31 is rectangle, heating chamber inner surface area is larger, heating chamber is heated more even, like this when after heater strip energising, upper by heating chamber of heat produced, under, left, right, back side uniform pickup, in heating chamber, spatial temperature distribution is more even, therefore dry matter homogeneous heating can be treated, ensure that heating cavity temperature is desired temperature, but also improve the efficiency of heating surface.
In addition, in order to increase the heat insulation effect of heating chamber, as a kind of preferred structure, the periphery of described heating chamber 3 also arranges a circle vacuum chamber 33, and the heat that heater strip 33 produces can not penetrate vacuum chamber 33, is all absorbed by heating chamber inner surface steel plate.Further, described vacuum chamber 33 periphery also arranges a circle insulation material 34, and insulation material 34 can prevent heat diffusion to outside casing 1 further.
General vacuum drying chamber all carries vavuum pump, and this just makes the volume of vacuum drying chamber comparatively large, is inconvenient to place and transport, and vavuum pump damages rear inconvenience maintenance, and whole drying box all can be scrapped.In order to head it off, as a kind of preferred structure, described casing 2 side is also provided with bleeding point 4, and described bleeding point 4 is communicated to described heating chamber 3, and described bleeding point 4 is for connecting vavuum pump.So when it is desired to be used, vavuum pump being connected on described bleeding point 4, when without the need to using, taking off vavuum pump, very easy to use.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
