For reaching above object, the technical solution adopted in the utility model is: provide a kind of distance adjustable liquid wastes microwave drier, comprise support, described cradle top surface is provided with drum; At least three support columns pass the end face of support from internal stent, the top of support column sets firmly container cover plate, and the lower surface of described container cover plate is connected with the skirtboard to downward-extension, and described skirtboard surrounds described drum; Described support bottom is provided with driving mechanism, and described driving mechanism is connected with described support column.
Further, described container cover plate is provided with center pit.
Further, the center of described container cover plate and the center of described skirtboard are consistent.
Further, described driving mechanism is chain drive mechanism, comprises drive sprocket and driven sprocket, and described driven sprocket is provided with the elevating lever being mated.
Useful technique effect of the present utility model is:
(1) adopt the technical solution of the utility model, simple in structure, convenient operation; Realized a small amount of material or be not easy to shift out drying property and the adaptive mensuration of microwave drying of on-the-spot material;
(2), by having skirtboard at cover plate, can realize the effective sealing to microwave; And the extension design of skirtboard can guarantee that microwave outlet is constant all the time apart from the height of material in dry run;
(3) container cover plate is provided with center pit, and feeding mechanism, wet-emitting blower, tensimeter and temperature measurement equipment can be installed;
(4) can guarantee the long-time running security of this device, reduce the long-term maintenance cost of using.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
The utility model provides the microwave drier of the adjustable processing radioactive liquid refuse of a kind of distance, its objective is further standardization radioactive liquid treatment of wastes produced equipment, strengthens the dry operability of processing of radioactive liquid refuse.
As shown in Figure 1-2, this microwave drier comprises support 1, and the end face of support 1 is provided with drum 2; More than three or three support columns 3 are from the inner end face through support of support 1, the top of support column 3 sets firmly container cover plate 4, container cover plate 4 is provided with center pit 7, the lower surface of container cover plate 4 is connected with the skirtboard 5 to downward-extension, skirtboard 5 surrounds described drum 2, for better cooperation, should guarantee that the center of cover plate and the center of skirtboard are consistent; In support 1 bottom, be also provided with chain drive mechanism 6, chain drive mechanism is connected with support column 3.
Wherein, container cover plate 4 is provided with center pit 7, and this center pit 7 adopts the bore of standard, is convenient to install feeding mechanism, wet-emitting blower, tensimeter and temperature measurement equipment.
The lower surface of container cover plate 4 is connected with the skirtboard 5 to downward-extension, its objective is for microwave is effectively sealed, and the lengthening of skirtboard 5 can guarantee that microwave outlet is constant all the time apart from the height of material in dry process.
Bottom, microwave hole adopts micarex to realize the sealing for microwave hole, effectively prevents that water vapor and the material splashing from entering microwave hole.
Chain drive mechanism, comprises drive sprocket and driven sprocket, and driven sprocket is provided with elevating lever 8, and elevating lever is provided with screw thread and is used in conjunction with driven sprocket.Under the drive of drive sprocket, driven sprocket rotates, and drives elevating lever to carry out lifting, thereby as required support column and container cover plate is promoted, to guarantee the increase along with bucket inner drying material, the constant distance on microwave outlet and material surface is in maximum power location.
This microwave drier removes necessary part can all adopt stainless steel, and simple in structure being easy to safeguarded, takes up room little, is convenient to realize a small amount of material or be not easy to shift out drying property and the adaptive mensuration of microwave drying of on-the-spot material.Long-time running security that can assurance device, reduces the long-term maintenance cost of using.
To processing microwave drier processing, the installation steps of radioactive liquid refuse, describe below:
