The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is done and to be described in further detail:

Fig. 1 is the structural representation of a kind of dryer of the utility model.Fig. 2 is runner, the pinkeye mouth structure stereogram of burner.From figure, can find out; The described dryer of the utility model; Be made up of insulation body 1, air inducing chamber 3,

air heating apparatus

2,11 of drying chambers, described air inducing chamber 3, described air heating apparatus 2 and described drying chamber 11 all are positioned at described insulation body 1; In 3 exits, described air inducing chamber, be provided with air-introduced machine 9; In described drying chamber 11 exits, be provided with exhaust blower 12; It is indoor that outdoor air is introduced air inducing by pressure fan 14, in air inducing chamber 3, formed hot blast by air heating apparatus 2 heating backs; Hot blast is transported in the drying chamber 11 by described air-introduced machine 9; Described hot blast carries out dried to containing wet stock in described drying chamber 11; Hot blast after the dried is discharged to outdoor by exhaust blower 12.

Described air heating apparatus 2 is made up of heat-exchanging tube bundle 6, clamshell 7 and 4 of burners; Described heat-exchanging tube bundle 6 devices adopt the mesh cloth interposed structure on described clamshell 5, be formed by connecting a series of " Y " font tube bank 6;

From Fig. 2, can find out that from Fig. 3 and Fig. 4 described burner 4 places below the clamshell 5; The fuel flow channel 15 of described burner 4 adopts vertical step by step forked arrangement, step by step to the mode that extends below, and the final pinkeye mouth 8 that is arranged in array that forms; Igniter is located at the center of burner.

Described drying chamber 11 is provided with a vertical central baffle 10, two Room about drying chamber is divided into, about two Room on top UNICOM, all portion is provided with multilayer dose laying rack 13 from bottom to top; The oven dry air-flow is from laying rack 13 interlayers, and between adjacent layer, flows through in the opposite flow direction structure of air-flow.

In air inducing chamber 3, above the described clamshell 5, be provided with heat exchange fin 7, fin 7 be shaped as rectangle or trapezoidal or triangle or parabola shaped.

Described burner 4 uses oil gas, natural gas to act as a fuel, and fuel combustion produces thermal-flame and directly heats described clamshell 5 through radiation and heat convection effect.In addition, the high temperature gas flow of described burner 4 burning generations from bottom to top heats described heat-exchanging tube bundle 6 through the heat convection effect under hot pressing function.

Consider that the single straight heat-exchanging tube bundle directly is arranged in the bigger temperature difference of easy generation on the clamshell 5, promptly very high in the local temperature near clamshell 5, and lower in the terminal temperature of heat-exchanging tube bundle, this is unfavorable for the efficient utilization that burner 4 burnings produce heats.For this reason, the heat-exchanging tube bundle 6 described in the utility model adopts network structure to arrange, is formed by connecting the tube bank of a series of " Y " font; Be that described heat-exchanging tube bundle 6 is to connect the shunting tube bank under the main flow tube bank from top to bottom successively; Connect a flowing bundle under the shunting tube bank, restrain until final stage toward lower bifurcation always, the final stage tube bank is connected with described clamshell loam cake; And every grade of runner is all vertical with its upper level runner, and caliber successively decreases step by step.Like this, the network structure of heat-exchanging tube bundle 6 is arranged, has made full use of the indoor space of air inducing, makes and can arrange bigger heat exchange area in the place near clamshell 5, helps improving the heat exchange effect of heat-exchanging tube bundle 6.In addition, the network structure of heat-exchanging tube bundle 6 arrange having realized high temperature gas flow that burning produces by body to compiling of point optimizing dispensing, unobstructed mobile in heat-exchanging tube bundle 6 of the air-flow that produces helps burning.

Can cause the too high and then scorification metal shell of clamshell temperature for avoiding flame directly to heat clamshell 5, side is furnished with heat exchange fin 7 in the air inducing chamber of described clamshell.The layout of heat exchange fin 7 has not only increased the air heat exchange area of air inducing chamber 3 sides and then has improved efficiency of utilization, also helps to reduce the operating temperature of clamshell 5, and then prolongs the working life of clamshell 5.Fin be shaped as rectangle, trapezoidal, triangle, parabola shaped etc.

The indoor air of described air inducing carries out delivering to described drying chamber 11 by described air-introduced machine 9 after the exchange heat through the heat exchange fin 7 on the described clamshell 5, described clamshell 5 bodies and described heat-exchanging tube bundle 6 these three kinds of heat exchange walls.

For making described burner can evenly heat described clamshell 5, this fuel that just needs each exit of burner to discharge is even.For this reason, the fuel flow channel of burner 4 adopts vertical forked arrangement mode in the utility model, and promptly subordinate's runner is perpendicular to higher level's runner, and the one-level one-level has finally formed the pinkeye mouth that is arranged in array to extending below, and is provided with igniter in the center of burner 4.

Described drying chamber is through two Room about establishing a central baffle 10 and being divided into; Dividing plate 10 leaves a segment distance with the drying chamber bottom; About two Room be equipped with along wall and contain the wet stock laying rack; The oven dry air-flow is from the laying rack interlayer, and between adjacent interlayer, the flow direction structure that airflow direction is opposite flow through in (being the serpentine configuration layout).

The drying course of this dryer is following: at first will contain wet stock and be placed on the laying rack 13, and open the control valve of fuel (oil gas, natural gas), fuel enters into burner 4 from air accumulator, and the starting ignition device takes fire.The heat that produces through air heating apparatus 2 burning carries out heat convection through the heat exchange wall and the indoor air of air inducing of clamshell 5, heat-exchanging tube bundle 6 and heat exchange fin 7; Under the effect of air-introduced machine 9, enter into drying chamber 11; In drying chamber 11, dry, finally discharge outdoor by exhaust blower 12 to containing wet stock.

Therefore, the utility model is rational in infrastructure, and is safe and reliable, and energy utilization rate is high, and the heat exchange effect is strong, and energy-conserving and environment-protective are beneficial to promotion and application.

More than narrated the technical scheme of the design and the enforcement of the utility model; Those skilled in the art can derive other a plurality of technical schemes, still under this design is instructed; Every various technical schemes under this design are all within the protection domain of claims of the utility model.
