Background technology
The monoblock type heating clamber of the drying chamber using in coating workshop at present, it is square structure, heat exchanger and filter with burner are installed in heating clamber, one end of this heating clamber is provided with air inlet, the other end is provided with air outlet, due to distinguished and admirable, can impact the bight in this heating clamber when entering or flowing out, after distinguished and admirable impact, form turbulent flow, thereby can form to the Air Flow in this heating clamber huge resistance, while the air after heating being sent to this heating clamber by drainage blower fan or pressure fan, need more powerful blower fan, not only increased equipment cost, and easily cause distinguished and admirable having some setbacks and phenomenon that air heat is inhomogeneous.
Utility model content
The utility model provides a kind of drying chamber monoblock type heater that can not produce air turbulence for the problems referred to above.
In order to solve the problems of the technologies described above, the utility model provides a kind of drying chamber monoblock type heater of following structure, it comprises chamber body, the front end bottom of chamber body is provided with air inlet, rear end lower is provided with air outlet, in chamber body, after going to, heat exchanger and the filter with burner is housed successively, its design feature is: front portion is equipped with and is positioned at burner the place ahead and by the deflector of chamber body top bight block in chamber body, in chamber body, the collection vane cover that is positioned at filter rear is equipped with at rear portion, the leading section that integrates vane cover be fixed on the inwall of chamber body and its front end as air inlet, rear end is gas outlet, the rear portion of chamber body is connected with circulating fan.
Described collection vane cover comprises that the front end ring of this involute shape ring cover is along being connected on the inwall of chamber body from going to rear bore involute shape ring gradually little and that be connected with the front end of blower fan wind-collecting cover cover.
Described deflector comprises by the upper arc of the involute shape being connected as a single entity and is connected to the above side arc of arc both sides of involute shape, the upper arc of involute shape is connected between chamber body roof inner surface and rear wall inner surface, and side arc one end is connected on the upper arc of involute shape, the other end is connected on the inner surface of chamber body sidewall.
Adopt after said structure, air enters after chamber body from air inlet, through the water conservancy diversion of deflector, can not impact the bight of chamber body, air after burner and heat exchanger heat, is filtered by filter more again, by collection vane cover and circulating fan, air-flow is drawn again, thereby no longer forming air turbulence, gas channel is more smooth and easy, the resistance while greatly having reduced Air Flow, thereby can use the blower fan of smaller power can realize distinguished and admirable circulation, save production cost.The concrete structure of collection vane cover and deflector is in order to reach best distinguished and admirable guide function.
In sum, the utility model can make the gas channel in air heat process more smooth, can not produce air turbulence, has advantages of simple in structure and saves production cost.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail:
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the structural representation that Fig. 1 overlooks;
Fig. 3 is the structural representation along A-A line is analysed and observe in Fig. 1.
The specific embodiment
Drying chamber monoblock type heater as shown in Figure 1 to Figure 3, for convenience of describing, the front portion that the direction that the air of take enters is this device, it comprises chamber body 1, the locular wall of chamber body 1 is made by trilaminate material, intermediate layer is heat-insulation layer, inner and outer surface layers is casing play, the front end bottom of chamber body 1 is provided with air inlet 2, rear end lower is provided with air outlet 3, in chamber body 1, after going to, heat exchanger 12 and the filter 13 with burner 11 is housed successively, the concrete structure of burner 11 and heat exchanger 12 is prior art, do not repeat them here, detonating fusee 14 is also housed on burner, chimney 15 is housed on heat exchanger 12, the interior front portion of chamber body 1 is equipped with and is positioned at burner 11 the place aheads and by the deflector 4 of chamber body 1 bight, top block, the collection vane cover 5 that is positioned at filter rear is equipped with at the interior rear portion of chamber body 1, collection vane cover 5 comprises from going to rear bore involute shape ring gradually little and that be connected with the front end of blower fan wind-collecting cover cover, the front end ring of this involute shape ring cover is along being connected on the inwall of chamber body 1, collect the rear end of vane cover and the wind-collecting cover of blower fan is connected, front end ring is along being connected with chamber body 1 inner wall sealing, thereby make distinguished and admirablely through collection vane cover, by blower fan, to be pumped, the leading section that integrates vane cover 5 be fixed on the inwall of chamber body 1 and its front end as air inlet, rear end is gas outlet, the rear portion of chamber body 1 is connected with circulating fan 6.
As depicted in figs. 1 and 2, deflector 4 comprises by the upper arc 41 of the involute shape being connected as a single entity and is connected to the above side arc 42 of arc 41 both sides of involute shape, the upper arc 41 of involute shape is connected between chamber body 1 roof inner surface and rear wall inner surface, and side arc 42 one end are connected on the upper arc 41 of involute shape, the other end is connected on the inner surface of chamber body 1 sidewall.
As shown in Figure 1, distinguished and admirablely from air inlet 2, along deflector 4, enter in chamber body 1, after heat exchanger 12 and filter 13, carry out abundant heat exchange, enter again collection vane cover 5, blade by circulating fan 6 is drawn air-flow, air outlet by chamber body 1 rear portion flows out again, the flow direction that the arrow line shown in figure is air.
The above is specific constructive form of the present utility model; the utility model is not restricted to the described embodiments; the art personnel, the equivalent variations based on concrete structure on the utility model and parts are replaced all in protection domain of the present utility model.
