Description

Heated-air circulation oven
Technical field
The utility model relates to medical drying unit, specifically refers to heated-air circulation oven, utilizes the heated air circulation type heating, constantly with the medicine heat drying in the baking oven, finally makes medicine reach the purpose of thermally equivalent.
Background technology
Traditional medicine heating, drying device, mainly by casing, and the heater or the electro-heat equipment formation that are arranged on box house, medicine is placed on heater or electro-heat equipment top, thereby utilizes heater or electro-heat equipment to the moisture in the medicine ambient air heating evaporation medicine.There is following shortcoming in the medicine heating, drying device of this mode: 1, energy waste is serious, and heater wherein needs constantly heating, have only a small amount of energy like this for the heating to medicine, and most heat energy is along with exhaust outlet is directly discharged.2, poorly sealed, therefore only be applicable to the medicine that indivedual environmental requirements are not high, for individually, the medicine of heating process and heating environment harshness, this method is inapplicable.3, heating-up temperature and the efficiency of heating surface are uncontrollable, and the heating process of these class heating means is comparatively slow, the medicine inequality of being heated.
The utility model content
The purpose of this utility model is to provide a kind of heated-air circulation oven, and this apparatus structure is simple, and cost is low, utilizes the heated air circulation type heating, constantly with the medicine heat drying in the baking oven, finally makes medicine reach the purpose of thermally equivalent.
Implementation of the present utility model is as follows: heated-air circulation oven, comprise the baking oven body, described baking oven body upper surface has an air admission hole, described air admission hole connects air inlet pipe, described baking oven body lower surface has a venthole, described venthole connects escape pipe, also is provided with the heating pressue device between described air inlet pipe and the escape pipe.
All also be equipped with drier in described air inlet pipe and the escape pipe.Sneak in the hot blast when the water evaporation in the medicine, chase escape pipe directly to enter in the drier, guarantee that circulation enters the interior heated-air drying of baking oven again and is not with moisture.The utility model is based on said structure, the process of its realization is: by the heating pressue device, air inlet pipe feeds hot blast, subsequently, hot blast enters the baking oven body, and be dispersed in uniformly in the baking oven body, under the effect of air pressure, hot blast is through behind the medicine, enter venthole, circulation enters in the heating pressue device again, after pressurization and heat treated, circulation enter air admission hole.The utility model is external with heater and pressue device, utilizes circulation pattern, can play the purpose of energy savings, can utilize hot blast that medicine is evenly heated simultaneously.
Prevent from causing behind the explosion accident pollution of environment when carrying out heat treated for the medicine to some active state, the utility model also comprises and is sleeved on the lip-deep explosion-proof shell of baking oven body housing.
Preferably, described explosion-proof shell is metal shell.
In order well to observe being heated and drying regime of medicine, described baking oven body simultaneously has breach, and this indentation, there is sealed with clear glass and forms the observation forms.
In order to cooperate the observation forms, described explosion-proof shell simultaneously has the observation breach, and described observation breach is positioned at observes the forms dead ahead.
Described observation breach is provided with the sealed transparent plate.
Preferably, be heated in order to prevent explosion-proof shell, have 5 centimetres to 10 centimetres gap between sealed transparent plate and the observation forms.
In addition, in order to make the wind speed step-down of air inlet, in order to avoid the placement state of medicine is impacted, so the utility model also comprises and is arranged on the baking oven body interior and is positioned at air distribution plate under the air admission hole.
In addition, in order to make the wind speed step-down of air inlet, in order to avoid the placement state of medicine is impacted, preferably, have some through holes on the described air distribution plate, this through hole is the horn shape through hole, and the osculum end of this through hole is near the air admission hole direction.The wind speed height of the air intake surface of this air distribution plate like this, and the area of air outlet increases, and can reduce the air velocity of air distribution plate outlet air surface, simultaneously, after the air-out, it is more even that its wind is laid.
Advantage of the present utility model is: crack performance can not take place because of being heated inhomogeneous in medicine thermally equivalent, particularly tablet medicine, and adopts circulating hot blast heating, can make and can not cause a large amount of wastes of the energy by energy maximum using.

The specific embodiment
Embodiment 1
As shown in Figure 1, 2.
Heated-air circulation oven, comprise baking oven body 2, described baking oven body 2 upper surfaces have an air admission hole 4, described air admission hole 4 connects air inlet pipe, described baking oven body 2 lower surfaces have a venthole, described venthole connects escape pipe, also is provided with heating pressue device 42 between described air inlet pipe and the escape pipe.
All also be equipped with drier in described air inlet pipe and the escape pipe.Sneak in the hot blast when the water evaporation in the medicine, chase escape pipe directly to enter in the drier, guarantee that circulation enters the interior heated-air drying of baking oven again and is not with moisture.The utility model is based on said structure, the process of its realization is: by the heating pressue device, air inlet pipe feeds hot blast, subsequently, hot blast enters baking oven body 2, and be dispersed in uniformly in the baking oven body 2, under the effect of air pressure, hot blast is through behind the medicine, enter venthole, circulation enters in the heating pressue device again, after pressurization and heat treated, circulation enter air admission hole.The utility model is external with heater and pressue device, utilizes circulation pattern, can play the purpose of energy savings, can utilize hot blast that medicine is evenly heated simultaneously.
Prevent from causing behind the explosion accident pollution of environment when carrying out heat treated for the medicine to some active state, the utility model also comprises the explosion-proof shell 1 that is sleeved on baking oven body 2 case surface.
Preferably, described explosion-proof shell 1 is metal shell, and preferred, metal shell is aluminum metal shell or albronze metal shell.
In order well to observe being heated and drying regime of medicine, described baking oven body 2 one sides have breach, and this indentation, there is sealed with clear glass and forms observation forms 21.
Observe forms 21 in order to cooperate, described explosion-proof shell 1 one side has observes breach 11, and described observation breach 11 is positioned at observes forms 21 dead aheads.
Described observation breach 11 is provided with the sealed transparent plate.
