Detailed description of the invention:
Below in conjunction with accompanying drawing, following describing in detail is done to the utility model.For sake of convenience, following " on ", D score, "left", "right" be consistent with the direction, upper and lower, left and right of accompanying drawing itself.
As shown in Figure 1, Figure 2, Figure 3 shows, samming drying machine, comprises a bracing frame 10, arranges for supporting drying box 20; Described drying box has the casing 21 of accommodating cavity by one and end cap 22 forms; The inside of described casing 21 is provided with twice screen pack 211; On described end cap 22, be provided with several material inlets 221 and a port 222; Immediately below described drying box 20, discharging opening is provided with splicing case 30; Described splicing case 30 is provided with feedback outlet 31 and valve 32; Described drying box 20 is furnished with a set of hot air circulating system.Described drying box 20 is arranged on support frame as described above 10 by holder 11 is dismountable.Described end cap 22 is locked by multiple snap close 212 and is paid in described hopper casing 21 top, and described snap close 212 is fixed on the lateral wall on described hopper casing 21 top.
Described casing 21 inside is provided with is detained funnel unit 90, described delay funnel unit 90; Described delay funnel unit 90 is by the first funnel 91, first pipeline 92, tapered cap 93, first muscle sheet 94, second pipeline 95, delay screen pack 96, second funnel 97 and the second muscle sheet 98.Described first funnel, 91 times edges are connected described first pipeline 92; Described first pipeline, 92 times edges are connected with described tapered cap 93; Described tapered cap 93 is connected with described second pipeline 95 by equally distributed four described first muscle sheets 94; Described second pipeline 95 is connected with described second funnel 97 by equally distributed four described second muscle sheets 98; Described delay screen pack 96 is arranged between described tapered cap 93 and described second funnel 97, and described second pipeline 95 is through described delay screen pack 96.Described casing 21 inside is provided with described in two groups is detained funnel unit 90.Be detained funnel unit 90 described in two groups to be connected with splicing case 30 by return pipeline 33.
Be provided with feedback outlet 31 below described splicing case 30, described feedback outlet 31 is connected with described material inlet 221 by adsorbent equipment, and material enters drying box 20 by this and carries out cyclic drying.Also be provided with valve 32 below described splicing case 30, material can be made after end drying to leave drying box 20.
Described drying box 20 is furnished with a set of hot air circulating system, described hot air circulating system by being fixed on the air-heater 50 of support frame as described above 10 side, the bellows 60 be connected with described air-heater 50 air outlet, the ventilation duct 70 be connected with described bellows 60 air outlet, the flexible pipe 80 be connected with described port 222, the filter 40 that is connected with described flexible pipe 80 form; Described ventilation duct 70 is through described end cap 22 center of circle, and the axis of rotation along described casing 21 enters described casing 21 bottom from top to bottom, and the outlet of described ventilation duct 70 is arranged downwards; The air outlet of described filter 40 is connected with described air-heater 50 air intake vent.
Operation principle: material enters described drying box 20 by described material inlet 221, described first funnel 91 is encountered in the process of down moving, material can be gathered in described first funnel 91, after assembling some materials, partial material is overflowed described first funnel 91 and is moved downward, the material that described first funnel 91 is assembled simultaneously can be moved downward by described first pipeline 92, have again partial material to leave described first pipeline 92 to move downward in described tapered cap 93 position, leftover materials enter described splicing case 30 through described second pipeline 95 and described return pipeline 33; From described first funnel 91 and described tapered cap 93 materials downward out by described delay screen pack 96, finally also enter described splicing case 30.Described delay screen pack 96 is evenly distributed with many bellmouths, and these bellmouths play the object of being detained material.The material entering described splicing case 30 has two kinds of results, and one is reach described material inlet 221 by adsorbent equipment via described feedback outlet 31 to carry out cyclic drying, and two is terminate drying by described valve 32.
In dry run; described air-heater 50 produces hot blast; hot blast enters described ventilation duct 70 by described bellows 60; drying box bottom is arrived again by described ventilation duct 70; due to hot blast motion principle; hot blast can from bottom to top move; contact with material in this motion process and reach drying effect; finally arrive described drying box 20 upper end; described filter 40 is reached by described port 222, described flexible pipe 80; dust granule in described filter 40 in air can be filtered, and finally totally enters described air-heater 50, proceeds to next circulation.
The foregoing is only preferred embodiment of the present utility model, therefore do not limit protection domain of the present utility model, every equalization change done according to the utility model all belongs in protection domain that the utility model contains with modifying.
