Description

Bulk material vibrating flowing dryer

The utility model relates to a kind of bulk goods vibration drying machine that flows and belongs to the drying machine class, is particularly suitable for that moisture content height, viscosity are big, granularity and the little bulk goods drying of proportion; The drying that also can be used for all the other all kinds of bulk goods.

The mobile drying device of domestic and international existing vibration at present, although it is of a great variety, structure is different, but substantially can be divided into vertical and horizontal two kinds of versions, it generally comprises the hothouse of large diameter single cartridge type and places several parts of vibrator, support spring and support of the certain exciting effect of generation below the drying box.The drying device of said structure form, big for granularity, viscosity is little, the drying of heavy bulk goods, gratifying effect is arranged, yet it is little for granularity, viscosity is big, moisture content is higher, it is poor just to occur the material fluidised form in the dry run of the bulk goods that proportion is little, defect such as wall sticking phenomenon is serious, and then cause drying efficiency low, speed is slow, ropy drawback, so there have drawback like this to show granularity after deliberation to be big, the fluidization degree of the easy dried material of the little grade of viscosity is influenced by the drying machine kinetic characteristic only, yet it is little for granularity, the fluidization degree of the difficult dried material of the big grade of viscosity is influenced by the kinetic characteristic of drying machine then not only but also is subjected to the influence of hothouse dimensional parameters very big, and the fluidizing performance of material is poor more, and the diameter of its hothouse is the rule that the little direction of trend changes.Secondly from making the material that is dried form normal fluidised angle as early as possible, the vibrator of above-mentioned drying machine places the following also unreasonable of drying box; Simultaneously the sticking serious problem of wall of the material that has is also awaited further solution.

It is a kind of that the purpose of this utility model is to provide, all kinds of bulk goods all are suitable for, select the most rational vibrator distribution form, structural parameters according to hothouse are determined its structural parameters with the matching relationship of the material rerum natura that is dried, and can prevent the mobile drying machine of bulk goods vibration of " sticking wall " phenomenon in dry run effectively.

The purpose of this utility model realizes by the following technical solutions, be by first and second drying box, vibrator and induced draught system are formed, described primary drying case comprises shell, bilateral symmetry at shell central horizontal face is provided with vibrator, be loaded on the support by four support springs, three hothouses vertically be arranged in parallel in it, two ends communicate with charging aperture and discharge gate respectively, one end is serially connected with the hothouse of connecting tube and redrying case, and the vibrator on it is arranged on the both sides of central horizontal face equally; Have the air-vent that communicates with the air inducing air entry on the sidewall of hothouse, have the turnover steam ports respectively at hothouse and the interbedded shell of shell upper and lower part.

Described hothouse is triangularly arranged on the cross section of shell, and wherein on the horizontal axis that two are arranged on the cross section, another is arranged on the following longitudinal axis of the horizontal axis in cross section.

The inner surface of described hothouse is coated with the polytetrafluorethylecoatings coatings of antiseized wall.

The utility model compared with prior art owing to structurally adopted redrying, the hothouse of three minor diameters, inner wall surface that antiseized wall coating is arranged; The redrying case is still continued to use the hothouse of large diameter single cartridge type; The a series of technical measures such as both sides of vibrator centering horizontal plane so there is the scope of application wide, all are suitable for all kinds of bulk goods, and rate of drying is fast, the efficient height, and quality is good, and advantages such as " sticking walls " is not implemented easily simultaneously, is beneficial to and applies.

Fig. 1 is a contour structures schematic diagram of the present utility model.

Fig. 2 is the A-A cross-sectional view.

Fig. 3 is the B-B cross-sectional view.

Embodiment of the present utility model is described in conjunction with the accompanying drawings, the shell the 24, the 20th of first and second drying box, by sheet material through welding fabrication, and hothouse 3,21 paralleled to the axis respectively pack in separately the shell 24 and 20, two ends link to each other with discharge gate 13,18 with charging aperture 7,25 respectively, by connecting tube 14 first and second drying box is serially connected, the other end of primary drying case links to each other with pay-off 9 by connection pipe 8, and the upper and lower part of shell 24,20 has the air inlet 12,17 and the exhaust outlet 5,23 of heating steam respectively; The air-vent 10,15 on its top links to each other with the air entry of air-introduced machine 16 by induced duct 11, and the shock electric machine 2 of YJZ-16-4 type is loaded on the both sides of the central horizontal face of shell 24,20; Be loaded on the support 1,26 by four support springs 6,19, be coated with polytetrafluorethylecoatings coatings 4,22 on the inner surface of hothouse 3,21, hothouse 21 is for continuing to use the hothouse of large diameter single cartridge type; Hothouse 3 distribution triangular in shape on shell 24 cross sections, wherein on the horizontal axis that two are arranged on the cross section, another is arranged on the longitudinal axis of horizontal axis bottom in cross section.

When the utility model uses, in advance the eccentric block of vibrator motor 2 is adjusted, make its working amplitude about 3mm, vibrating dryer is brought into operation, then from air inlet 12,17 feed superheated steam to hothouse 3,21 heat, chamber 3 to be dried, 21 materials that are dried when reaching operating temperature can be by pay-off 9 in charging aperture 7 enters primary drying chamber 3, be in the material of fluidized state, the fierce upset of next edge hothouse sidewall of vibration at vibrator 2, slowly move vertically on one side, because the continuity of feed, make the material in hothouse form a continuous spiral helicine fluid, because fluidised effect, make the material that is added into be advanced to exhaust end through behind the certain hour, finish primary drying by discharge gate 13 discharges, process connecting tube 14 is in charging aperture 25 is sent into redrying chamber 21, the moisture content of the material behind primary drying has reduced much, so its fluidizing performance improves, so after entering large diameter single cylinder drying chamber 21, inner surface has anti-stick coating in addition, the reasonable Arrangement of vibrator 2, therefore the thing that is dried reaches fluidized state very soon, its motion state is identical during with primary drying, induced duct 11 self-induced-air mouths 10 are passed through by air-introduced machine 16 in the moisture limit that the limit drying is evaporated, 15 siphon away, and dry good material is discharged from discharge gate 18.The steam of cooling is discharged from from exhaust outlet 5,23, thereby realizes the purpose to the bulk goods drying.
