Abstract

The utility model relates to a vacuum rotating drying box which is composed of a box body, a drying tank and a heater. The utility model is characterized in that the box body is provided with a vacuum pump, the drying tank is provided with a plurality of rows of small holes, one end of the drying tank is connected to a rotating motor, and the drying tank can be rotated. Materials can automatically turn and mix following the rotation of the drying tank under the vacuum state. The utility model has the advantages of large heating area, uniform heating and large evaporation capacity and can enhance drying speed and drying efficiency.

Description

Vacuum Rotary drying case

The utility model relates to a kind of drying device, relates in particular to carry out evenly dry drying box under vacuum state.

The dry all kinds of materials of drying box commonly used in all trades and professions.As discolour silica gel is the drier of using always, and its advantage is to use repeatedly, and discolour silica gel will lose efficacy because of absorbing moisture content in use for some time.Often the discolour silica gel that lost efficacy need be carried out for this reason that drying makes it water evaporates and reclaim again and use.Method at present commonly used is that the discolour silica gel that will lose efficacy is placed on drying box and carries out heat drying and handle, and makes it water evaporates.But carry out drying with present drying box and often have following problem: the one, discolour silica gel is deposited on the plate of drying box and carries out drying, tend to cause heating inhomogeneous, the 2nd, present drying box all is to carry out drying under normal pressure, and dry moisture content is not easy evaporation under the normal pressure.Effect is undesirable during therefore with materials such as the dry discolour silica gels of current drying case.

The purpose of this utility model is to provide a kind of drying box, to overcome above-mentioned shortcoming.

For achieving the above object, drying box of the present utility model is made up of casing, drying chamber and heater.It is characterized in that: vacuum extractor is housed on the casing, and drying chamber is provided with many row's apertures, and an end is connected to change and revolves on the motor, and is rotatable.

Adopt the drying box of said structure, when materials such as dry discolour silica gel, because drying chamber one end is connected on the electric rotating machine, material turns automatically continuously with the rotation of drying chamber when dry, and heating surface area is big, homogeneous heating.Vacuum extractor is housed on casing, can makes drying box under negative pressure, carry out drying, help the water evaporates of material, can save heat time heating time, raise the efficiency.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is the structural representation of the utility model vacuum Rotary drying case.

Fig. 2 is the cutaway view of Fig. 1 along the A-A line.

Shown in Figure 1, the utility model vacuum Rotary drying case is made up of casing (1), drying chamber (2) and heater (3).Casing (1) is provided with vavuum pump (4), temperature-sensing probe (5), the wet probe of sense (6), electric rotating machine (7), vacuum meter (8) and gate valve (9), (10).Be provided with catch tray (11) in the casing (1).Also be provided with chamber door (12) on the casing (1).Electric rotating machine (7) is fixed on the casing (1) with fixed mount (13).Drying chamber (2) is provided with many row's apertures (14), and an end of drying chamber (2) is connected on the electric rotating machine (7) by the sealing rubber cover (16) that turning cylinder (15) passes on the casing (1).Drying chamber (2) middle part is fixed on the casing (1) with rolling bearing (17), screw (18) and clamping plate (19).The other end of drying chamber (2) is provided with iron gate (20), and iron gate (20) is provided with observation panel (21).Iron gate (20) is fixed on the drying chamber (2) with rotating screw cap (22), mobile fixed bar (23).

Shown in Figure 2, polylith iron plate (24) is housed in the drying chamber (2).

When dry, material is packed in the drying chamber (2), open heater (3), start vacuum pumping pump (4), electric rotating machine (7), can make material rotational automatic drying that turns continuously with drying chamber (2) under vacuum state.
