The utility model is to realize like this; by pulverizing; wet starch after raw materials for production behind the mill oar dewater by water extracter is delivered to the pulsed gas flow drying installation by spiral conveyer; drying installation is the calorifier that adopts driven by motor; on connect the ascension pipe of drying tube that falls " U " shape of drying installation; ascension pipe is to adopt the pipe of segmentation reducing to join to form; the upper end is connecting descending sedimentation pipe with the semicircle shape bend pipe; ascension pipe and down pipe all outer lining with thermal insulation layer and outer skin protective layer; descending sedimentation pipe lower end is connecting the cyclonic separator import with the circular arc bend pipe; cyclonic separator upper end air outlet inserts the air compartment that disappears; the lower end discharge port is isolated cyclonic separator and starch pond with foliated lamellar choke feeder; and at any time with sedimentation starch in falling the starch pond, whole drying installation height is 8-30m.The input hot blast temperature is 60-85 ℃, and rising material manage-style speed is the 2.5-4 meter per second.
The utility model can also be finished with the secondary air flow drying mode, its structure is to adopt two single-stage pulsed gas flow starch drying installation series connection, bag filter formula of two same accesses of cyclonic separator air outlet disappears in the air compartment, cyclonic separator in the first step moisture eliminator adopts sped structure, and will insert in the calorifier of the second stage under the discharge port, second stage moisture eliminator adopts straight formula cyclonic separator.
Uphill line of the present utility model is to adopt rise material pipe and the buffer tube of the alternate 2-5 group of thickness to link successively and form, descending sedimentation pipe is identical with the buffer tube internal diameter, rise the material pipe: the diameter of semicircle bend pipe, circular arc bend pipe is elected ∮ 300-1000mm as, and buffer tube, sedimentation pipe internal diameter are ∮ 600-1500mm.
It is to adopt 20 ° of-60 ° of garden frustum pipes to connect transition with buffer tube that each section of the present utility model rises the material pipe, and top semicircle shape bend pipe internal diameter is identical with liter material pipe, and connects with buffer tube and sedimentation pipe with 20 ° of-40 ° of garden frustum pipes.
Advantage of the present utility model is that the ascension pipe of drying pipeline and down pipe are to adopt the alternate pipeline of thickness to combine; increased the abundant duration of contact of hot blast and warm starch; the thermal insulation layer of drying pipeline and protective layer heat waste reduce; increase work-ing life more than 2 times; particularly the gelatinization of starch is resolved the horizontal vertical drying that changes into; again single air-flow is changed into two air stream dryings; heat energy is fully used; the dry rate ratio of starch improved more than 90% originally; day economizes on coal than original reduction by 35%; economize on electricity 10%; make starch per ton reduce cost 12.33 yuan,, improved the quality of starch because the drying unit after improving is worked continuously; whiteness is brought up to more than 88 ° by original 85 °; viscosity is brought up to 270 °-290 ° by original 180 °-190 °, improved the capacity of competition of product, and whole plant reduces investment outlay 85% than former import; reduce cost 65% than existing equipment, starch factory is transformed the recoverable then investment of original drying installation more than 5 times.
Now contrast accompanying drawing and describe a most preferred embodiment of the present utility model.
Accompanying drawing 1 is the dry structure iron of single-stage of the present utility model.
Accompanying drawing 2 is the dry structure iron of two-stage of the present utility model; Among the figure 1, calorifier, 2, rise the material pipe, 3, buffer tube, 4, the semicircle bend pipe, 5, sedimentation pipe (down pipe) 6, circular arc bend pipe, 7, cyclonic separator, 8, the air compartment that disappears, 9, the choke feeder, 10, spiral conveyer.
Wet starch shown in the figure after processing grinds dehydration; send in the calorifier (1) of pulsed gas flow starch drying installation; calorifier (1) blast inlet is by the vapor heated hot blast of boiler; connecting riser on the air outlet rises three groups of drying tubes that material pipe (2) and one section buffer tube (3) form by one section and forms; its top is connecting the descending sedimentation pipe of feed (5) with the semicircle bend pipe; whole drying tube is unified into down " U " type structure; whole drying tube all is made up of interior pipe and outer protective layer and intermediate thermal insulating layer; interior effective galvanized sheet is rolled into; outer protective layer is made with the 0.5mm galvanized sheet; intermediate thermal insulating layer is made filling with asbestos; joining cyclonic separator (7) in sedimentation pipe (5) lower end with the circular arc bend pipe; the cyclonic separator upper end disappears with a pipe feeding bag filter formula in the air compartment (8); the exit, lower end is equipped with choke feeder (9), and with pipe blanking is sent in the starch pond and to be screened.
