Abstract
The utility model discloses a stirring type microwave vacuum drier comprising a heating tank body provided with a feed pipe and a vacuum interface as well as a discharge pipe at the bottom, and a radiation heating device and a stirring device are arranged on the housing wall of the heating tank body. Materials enter the heating tank body through the feed pipe, then a vacuum pump is activated to form a vacuum subpressure state in a heating body via the vacuum interface, meanwhile the stirring device performs forced rotary stirring and turn-over mixture to the materials, and the radiation heating device performs radiation heating to the materials. Since the materials are always under the 'dynamic' and vacuum subpressure, the heating to the materials is more uniform, and the drying speed is faster.
Description
Technical field
The utility model relates to a kind of drying equipment, especially a kind of stirring-type microwave vacuum dryer that utilizes microwave to heat continuously under vacuum state.
Background technology
In recent years, microwave-heating drier equipment was more and more by the first-selection of every profession and trade manufacturing enterprise as the heat drying equipment needed thereby of product.But microwave dryer product in the market is divided into tunnel type, van-type, the cabinet type three kinds of series of products of circle substantially.1. the operation principle of tunnel type is: front end is reinforced, top heating using microwave, and the rear end discharging is transmitted by conveyer belt.In the heat drying process, be heated materials dried and all be exposed among air, the dust like this, the cross pollution of air, dust takes place easily, contain in the material process of inflammable and explosive composition, the combustion explosion phenomenon can take place at heat drying.
2. van-type, the circle cabinet type because of being subjected to effects limit such as microwave wavelength and microwave property, the volume of its calandria can not be excessive, thereby limited the production and processing amount of its equipment.In addition, van-type, round cabinet type reinforced discharging are by people's tool disk, artificial placing, thereby increase labor intensity of operating personnel, to big in batches product, need adding several times dry, can't guarantee the uniformity of every physical index of every batch.Also have the cabinet type feeding gate of van-type, circle too big, in case the special micro-wave screening sealing strip that is equipped with on the door damages, can cause the injury of microwave radiation between the operating period operating personnel.
The utility model content
Problem to be solved in the utility model is at above the deficiencies in the prior art, provide a kind of and can under vacuum state, adopt heating using microwave, transmit the material heat drying continuously and heat the stirring-type microwave vacuum dryer more even, that rate of drying is fast, safe in utilization.
For addressing the above problem, the utility model by the following technical solutions:
A kind of stirring-type microwave vacuum dryer comprises the heating casing, and the heating casing is provided with feed pipe and vacuum interface, and the bottom is provided with discharge nozzle, and described heating casing is provided with radiant heating device and agitating device.
Below be the utility model for further improvement of these options:
Described heating casing comprises upper box body and the lower part box that is tightly connected, and described lower part box is tapered, and is obliquely installed.
Further improve: the bottom of described lower part box has the casing diapire, and described discharge nozzle is arranged on its lowest position near the casing diapire.
Further improve:
Agitating device comprises the motor that is installed in the casing bottom wall outer and is installed in the interior stirring vane of lower part box that described stirring vane and motor are in transmission connection.
Further improve: described radiant heating device comprises the microwave generator that is installed on the upper box body.
Further improve:
The top of described upper box body has the casing upper wall, and described microwave generator is installed on the casing upper wall.
The utility model adopts such scheme, material enters in the heating casing by feed pipe, opening vavuum pump then makes by vacuum interface and forms vacuum negative pressure condition in the calandria, the driven by motor stirring vane is forced rotation to be stirred to material and is stirred mixing simultaneously, be installed in the microwave generator on the casing upper wall, material is carried out radiation heating, because of material is under " dynamically " and the negative pressure of vacuum all the time, so the heating of material is more even, rate of drying is faster, because of the heating casing is closed, avoided microwave source operating personnel to be caused the injury of microwave radiation again.
The volume of the utility model heating casing can design and produce according to the amount of heat drying, realizes disposable reinforcedly, and after heat drying was finished, disposable discharging was assisted discharging by the paddle rotation during discharging, has accomplished to save time, the saving of labor is laborsaving again.
The utility model is described in further detail below in conjunction with drawings and Examples:
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment.
Among the figure: the 1-upper box body; The 2-feed pipe; The 3-discharge nozzle; The 4-support; 5-casing diapire; The 6-motor; The 7-stirring vane; The 8-vacuum interface; The 9-microwave generator; 10-casing upper wall, 11-lower part box.
The specific embodiment
Embodiment, as shown in the figure, a kind of stirring-type microwave vacuum dryer, comprise a heating casing of making by stainless steel material, the heating casing is installed on the support 4, described heating casing comprises upper box body 1 and the lower part box 11 that is tightly connected, described lower part box 11 is tapered, and be obliquely installed, the upper end of upper box body 1 is provided with feed pipe 2 and vacuum interface 8, the bottom of lower part box 11 is provided with discharge nozzle 3, lower part box 11 has casing diapire 5, described discharge nozzle 3 is arranged on the lowest part position near casing diapire 5, on casing diapire 5, agitating device is installed, this agitating device comprises motor 6 that is installed in casing diapire 5 outsides and the stirring vane 7 that is installed in the lower part box 11, described stirring vane 7 is in transmission connection with motor 6, the top of upper box body 1 has casing upper wall 10, on casing upper wall 10, be provided with radiant heating device, described radiant heating device comprises that frequency is the multibarrel microwave generator 9 of 915～2450MHZ,, can carry out radiation heating to the material in the heating casing.
During work, material enters in the heating casing by feed pipe 2, opening vavuum pump then makes by vacuum interface 8 and forms vacuum negative pressure condition in the calandria, 7 pairs of materials of motor 6 drive stirring vanes are forced rotation to be stirred and are stirred mixing simultaneously, be installed in two microwave generators 9 on the casing upper wall 10, material is carried out radiation heating, because of material is under " dynamically " and the negative pressure of vacuum all the time, so the heating of material is more even, rate of drying is faster.
Through prototype test, calandria of the present invention can disposablely feed in raw material to the material of need heat drying, the dry disposable discharging in back, whole heat drying process is to carry out under the negative pressure of vacuum full closeding state, be more suitable for pharmaceutical manufacturer all kinds of medical material Chinese medicine extracts, and the part chemical products heat drying technology is had the enterprise of specific (special) requirements, guarantee that the every physical index behind the material heat drying keeps unified.
