Description
Technical field
It the utility model is related to medicine processing, more particularly to a kind of small-sized injection baking oven ducting system.
Background technology
Current existing small pin baking oven uses upper air discharge structure more, and this streamer mode inevitably has sinuous flow feelings
Condition, so that warming skewness, influence medicine clarity；And existing lower air discharge structure, it is direct air-out mostly, though its
Sinuous flow situation so is not present, but its caused heat distribution inhomogeneities is more undesirable, it is necessary to be improved.
Utility model content
The utility model provides a kind of small-sized injection baking oven ducting system, to solve above-mentioned prior art deficiency, by tradition
Upper wind output channel be changed to lower wind output channel, and enable to air intake homogenization at the top of baking oven, avoid and be likely to occur sinuous flow
, it is ensured that flow direction is consistent and uniform in baking oven, improves medicine clarity.
In order to realize the purpose of this utility model, intend using following technology：
A kind of small-sized injection baking oven ducting system, including circulating fan, air-supply passage, baking oven casing, air exhaust passage, return air
Pipe, baking oven casing inner top are provided with least two heating rods, and baking oven cabinet wall is provided with heat-insulation layer, it is characterised in that baking oven case
Air inlet is provided with the top of body, circulating fan connects air inlet by air-supply passage, and air-supply passage is up-narrow and down-wide, is set in air-supply passage
There is tapered shunting rack, the height of tapered shunting rack is the 1/3~1/2 of air-supply passage height, and tapered shunting rack bottom is straight
Footpath is the 2/5~2/3 of air inlet width, and tapered shunting rack bottom is with air inlet in the same horizontal position, tapered shunting rack
Mesh aperture be 2~4mm, spacing is 2~5mm, and baking oven bottom half has exhaust outlet, exhaust outlet mouth side and baking oven wall box
Between be provided with tilt diversion platform, exhaust outlet connection conical flow guiding passage, conical flow guiding passage connect both sides air exhaust passage, air draft
Passage connects backwind tube, backwind tube connection circulating fan.
Further, it is heating rod below the air inlet, is shelf below heating rod.
The beneficial effects of the utility model are：Homogenization diffusion is carried out to distinguished and admirable so that blow to and add since air-supply passage
The fluid of hot pin and shelf homogenizes, and is converged from diversion platform is tilted to after exhaust outlet, is arranged by conical flow guiding corridor diversion to each side
Wind passage, circulating fan being finally back to, whole process airflow direction remains from top to bottom, is not in that sinuous flow is possible,
And the particular design of air-supply passage can ensure that air-flow homogenizes, be advantageous to improve medicine clarity.
Brief description of the drawings
Fig. 1 shows the utility model structure diagram.
Embodiment
As shown in figure 1, a kind of small-sized injection baking oven ducting system, including circulating fan 3, air-supply passage 31, baking oven casing
1st, air exhaust passage 51, backwind tube 33, the inner top of baking oven casing 1 are provided with least two heating rods 2, and the inwall of baking oven casing 1, which is provided with, to be protected
Warm layer 11.The top of baking oven casing 1 is provided with air inlet 12, and the lower section of air inlet 12 is heating rod 2, and the lower section of heating rod 2 is shelf 4.Follow
Ring blower fan 3 connects air inlet 12 by air-supply passage 31, and air-supply passage 31 is up-narrow and down-wide, and tapered shunting is provided with air-supply passage 31
Rack 32, the height of tapered shunting rack 32 are the 1/3~1/2 of the height of air-supply passage 31, the base diameter of tapered shunting rack 32
For the 2/5~2/3 of the width of air inlet 12, the bottom of tapered shunting rack 32 is with air inlet 12 in the same horizontal position, tapered shunting
The mesh aperture of rack 32 is 2~4mm, and spacing is 2~5mm, and exhaust outlet 14 arranged at the bottom of baking oven casing 1,14 mouthfuls of sides of exhaust outlet with
It is provided between the side wall of baking oven casing 1 and tilts diversion platform 13, exhaust outlet 14 connects conical flow guiding passage 5, and conical flow guiding passage 5 connects
The air exhaust passage 51 of both sides, air exhaust passage 51 connect backwind tube 33, and backwind tube 33 connects circulating fan 3.Heating rod 2 connects electricity
Source.
Medicine administered by injection is placed in shelf 4, opens heating rod 2, ON cycle blower fan 3.Circulating fan 3 is by air-supply passage 31 to entering
Air port is blown, due to being up-narrow and down-wide, so the wind sent out can the trend that spreads of oriented both sides, have tapered shunting rack in addition
32 presence, the wind of center section pass through tapered shunting rack 32, have part can be directly through the mesh of tapered shunting rack 32
Entered by air inlet 12 in casing, there is part to be blocked by the support body of tapered shunting rack 32, to both sides baffling, so as to further
The air-supply of air-supply passage 31 is homogenized, the design at aperture size and interval, uniform divided flows effect, tapered shunting net can be optimized
Height and the diameter base size design of frame 32, as far as possible more the wind of air-supply passage 31 can be shunted, while again
It is unlikely to excessively to influence flow velocity.Wind after homogenization passes through heating rod 2, takes away heat, flows to shelf 4, acts on shelf 4
Medicine administered by injection, bottom exhaust outlet 14 is then flowed to, due to there is the presence for tilting diversion platform 13 so that fluid in casing can be with bottom
Quickly converged to exhaust outlet 14, after the shunting of conical flow guiding passage 5, wind flows back from the air exhaust passage 51 of both sides, by returning
Airduct 33 enters circulating fan 3.
