Embodiment
Fig. 1 is the structural schematic diagram of the drying kiln 100 in the embodiment of the present invention;Fig. 2 is the top view of Fig. 1;Fig. 3 is figure 1 along line A-A cross-sectional view;Fig. 4 is cross-sectional view of the Fig. 1 along line B-B;Fig. 5 is the topology view of the trolley in the present embodiment;Fig. 6 For the lateral view of Fig. 5.
Fig. 1-Fig. 6 is please referred to, the drying kiln 100 in the present embodiment includes kiln body 10, lifting door system 20, multiple is used for Carry trolley 30, heating system 40, the dehumidification system 50 of part W1 to be dried.Kiln body 10 has the drying extended along first direction Y1 One end of room Q1, drying room Q1 are equipped with opening K1.Lifting door system 20 includes door frame 21, wicket 22, the mobilizable peace of wicket 22 Loaded on door frame 21.Wicket 22 is configured to rise along door frame 21 to open opening K1 or drop to closing opening K1.It is multiple Trolley 30 is along first direction Y1 close-packed arrays in drying room Q1.Each trolley 30 all have between the upper and lower every two layers in the horizontal direction Plummer 31, for carrying part W1 to be dried.Isolation board 32, and multiple trolleys are equipped between two layers of plummer 31 of trolley 30 30 isolation board 32 is successively contradicted along first direction Y1, formed by drying room Q1 be separated between the upper and lower every upper space Q2 and under The separate layer of sheaf space Q3.Upper space Q2 and lower layer space Q3 is vertical by first on wicket 22 close to one end of wicket 22 Channel T1 connection.The one end of upper space Q2 and lower layer space Q3 far from wicket 22 by kiln body 10 far from opening one end K1 the Two vertical passageway T2 connection.Upper space Q2, the second vertical passageway T2, lower layer space Q3, the first vertical passageway T1 successively head and the tail Connection forms circular passage T0.Heating system 40 includes heater 41, and heater 41 is connected to circular passage T0, and is adapted to It is enough formed be circulated in the T0 of circular passage heat it is distinguished and admirable.Dehumidification system 50, the wet-emitting blower 51 including being connected to circular passage T0.? In an embodiment of the present embodiment, heater 41 is connected at the second vertical passageway T2, is supplied from the second vertical passageway T2 Answer hot wind.When needed, it can control air-out direction, form positive, reversed circulation, realize more drying effect.This implementation Wet-emitting blower 51 in example may be disposed at the roof of kiln body 10 near its K1 that is open, and be connected to from the hole of the roof of kiln body 10 Upper space Q2.The moisture in drying room Q1 is discharged in starting wet-emitting blower 51 when needed.
Drying kiln 100 in the present embodiment is in use, rise wicket 22 to open the end drying room Q1 along door frame 21 Opening K1, the multiple trolleys 30 for being mounted with workpiece to be dried are pushed into drying room Q1 one by one;Wicket 22 is fallen again, makes kiln Door 22 closes drying room Q1.Pass through the separation of the isolation board 32 of trolley 30 and the first vertical passageway T1, the second vertical passageway T2 Connection, the interior circular passage T0 formed vertically of drying room Q1.Start heating system 40 and dehumidification system 50,40 shape of heating system Wind is heated at the thermal convection recycled along circular passage T0;At the same time, it is vapored away from workpiece after the discharge of dehumidification system 50 heating Moisture, the final drying realized to workpiece.
Drying kiln 100 in the present embodiment is convenient to opening and closing drying room Q1, and the heat of circular passage T0 circulation is right Stream heating wind, drying efficiency is high, time-consuming short, and saves space occupied.
In an embodiment of the present embodiment, for the structural stability for improving door frame 21, the top of door frame 21 passes through Hound 60 supports the roof for being connected to kiln body 10.
For convenience of the opening and closing of wicket 22,22 vertical lifting of wicket is avoided directly to touch kiln body 10 and the interference of kiln body 10, in kiln Door 22 has gap between the opening K1 for the extreme lower position and kiln body 10 that door frame 21 drops to.The bottom of wicket 22 is provided with rolling 22a is taken turns, and being capable of opening K1 close along first direction Y1 and closing kiln body 10 positioned at the wicket 22 for falling position.By setting Gap is set, is then rolled along first direction Y1 to realize the closing to the opening K1 of drying room Q1, has that opening and closing is convenient, avoids doing The effect related to.
To realize that the isolation board 32 in the present embodiment hermetically separates the upper down space of drying room Q1, the present embodiment it is each The isolation board 32 of trolley 30 needed along first direction Y1 it is sealed against one another.Its set-up mode are as follows: 32 edge of isolation board of trolley 30 One end of first direction Y1 is equipped with sealing plate 32b, the other end is equipped with sealing convex edge 32c.The isolation board of two adjacent trolleys 30 32 corresponding sealing convex edge 32c are configured to seal against in sealing plate 32b.When row's trolley 30 along first direction Y1 according to When secondary close-packed arrays, the opposite pressing of opposite sealing plate 32b and sealing convex edge 32c of two adjacent trolleys 30.Sealing plate 32b and Sealing convex edge 32c, at least one uses elastic material such as rubber, to realize sealing.
There is wicket 22 in the present embodiment horizontal endplate 22b, endplate 22b to be configured to corresponding abut most Isolation board 32 on the trolley 30 of wicket 22.The outside of wicket 22 is being enclosed by thermal insulation board towards the opening K1 of drying room Q1 At box-shaped enclosure 22c.First vertical passageway T1 is separated from box-shaped enclosure 22c.
To realize that the isolation board 32 in the present embodiment hermetically separates the upper down space of drying room Q1, the present embodiment it is each The isolation board 32 of trolley 30 needs to distinguish palette with the two sidewalls of drying room Q1 on vertical first direction Y1.Its embodiment party Formula are as follows: corresponding sealing strip 11 is provided on the two sidewalls of drying room Q1, the width of the isolation board 32 of trolley 30 is outside to two sides Protrusion forms the raised line 32a that sealing is matched with sealing strip 11.For convenience of the installation of sealing strip 11, two inner sidewalls point of drying room Q1 It is not provided with the mounting bar 12 extended along first direction Y1, sealing strip 11 is connected on mounting bar 12, and downward palette Raised line 32a.In this way, drying room Q1 can be easily slid into trolley 30, and after slide-in drying room Q1, the two sides of isolation board 32 The two sidewalls of palette drying room Q1 can be distinguished, to realize lateral sealing.
It is arranged by the above-mentioned sealing structure along first direction Y1, vertical first direction Y1, can ideally realizes separation The upper down space of drying room Q1, it is ensured that circulation canal it is complete.
In summary it describing, the drying kiln 100 in the embodiment of the present invention has the drying room Q1 that can facilitate opening and closing, and Wind is heated in the thermal convection of circular passage T0 circulation, and drying efficiency is high, time-consuming short, and saves the beneficial effect of space occupied.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
