Abstract

The utility model relates to a device used in the drying of the material. An annular machine body composed of multi-layer annular horizontal hole plates can generate vibration by adopting two vibrating motors. Thus, the material flows from the upper layer to the lower layer successively along the annular hole plates, and the hot air blows from the lower layer and successively passes through the hole plates of each layer to form countercurrent with the material flow. A vibratory feeding device is arranged below a material inlet, and a material outlet can make the materials on and under the hole plates of end layer discharge in one hole. A limiter is arranged between a machine frame and a bottom board of the machine body. The utility model has the characteristics of simple structure, small ground occupation, continuous work, high efficiency, good drying effect, high heat utilization, etc. The utility model is suitable for the drying process of various materials.

Description

Vibratory horizon circular multiplate dryer

The utility model is a kind of equipment that is used for drying materials.Directly contact with water-containing materials at present with hot blast and make that the drying machine of its oven dry uses always pneumatic drier, fluidized bed drying machine and vibrating dryer arranged.Vibrating drier is owing to mainly be to utilize vibration to make material move, stir, and hot blast mainly plays desiccation.So compare the air quantity that needs with fluidized bed drying machine, pneumatic drier few, blast is low, thus can adopt the little fan with low voltage of installed capacity, and be not subjected to the influence of material proportion, granularity difference.Obtain the drying effect of homogeneous.And mostly the vibrating dryer that uses at present is the horizontal vibrating dryer of individual layer orifice plate, and its shortcoming is that floor space is big, and hot blast only once just contacts with material and discharged.So the heat utilization ratio of hot blast is very low, need to increase a set of equipment and adopt waste gas to reclaim.The vibrating screw drying machine is still arranged in addition, and this kind drying machine makes material move from bottom to top and hot blast also is from bottom to top by material bed along helicla flute.Be hot blast and material following current, its shortcoming is that the heat energy utilization rate of hot blast is low.The oscillatory type multistage continuous drier of an also useful vibrating motor exciting, its material operation is radially to flow to the edge from the orifice plate center, again circulation.Variant radius material flow does not wait, and the center is the dead point, and the material stroke do not wait, and structure is also complicated so do not reach the purpose of homogeneous drying.

The utility model is a kind of of vibrating dryer.Its structure such as figure one are by cover plate (1), body (2), and isolation spring (3), frame (4), vibrating motor (5), stopping means (6) is formed.Body such as figure two are folded to fall to combining by some ring bodies.Ring bodies is the ring-shaped orifice plate (9) that level is housed in the annulus (5) that constitutes of the cylinder by two different-diameters, and every layer of orifice plate has material along radial direction and fall mouthful (8), and each layer material falls and mouthful expect a mouthful position along reverse staggering one of material flow.One feed bin (7) is arranged below ground floor ring bodies material inlet, one adjustable gate (6) is housed, in order to the control mass flow along flow direction of material.Feed bin (7) and gate (6) constitute a vibrating material feeding device.There is cover plate (1) on the body top, and hot-wind inlet (2) is arranged on the cover plate, air outlet (3).Feeding mouth (4).Have hot blast introducing port (10) on the inner tube wall of undermost ring bodies, outer tube wall has material outlet (11), and discharging is housed chews (12), and the discharging opening structure makes the upper and lower material normalizing of end layer orifice plate.Organism bottom is equipped with the vibrating motor of two interlaced arrangement.Body is supported on the frame by several springs.The performance of these isolation springs can guarantee machine in super resonance region work, thereby it is little to make machine pass to the dynamic load of ground.Can fix without lower margin, machine can float to be placed on the ground and work, and conveniently moving.Four stopping means are housed, in order to prevent meet accident accident and guarantee the drying machine whole Transporting of machine on the symmetric position between organism soleplate and frame.This stopping means is on four angles, plane on the frame four screw rods to be housed symmetrically, passes in the corresponding hole of frame bottom plate, respectively revolves a disk on the upper and lower position, hole, and the relative support of disk simultaneously is equipped with block rubber.The upper and lower locking nut that all is equipped with of disk has promptly constituted stopping means.

The utility model working condition is the exciting of vibrating motor, makes body produce vertical straight-line oscillation and around the twisting vibration of vertical axis.Material enters feed bin (7) from feeding mouth (4), advances do horizontal vaults along one deck ring-shaped orifice plate through gate (6), walks a circumference, falls into two layers by one deck discharging opening (8), and the circumference of going further falls into down one deck successively.Chewing (12) by the discharging of the most last layer at last discharges.Meanwhile, the hot blast of uniform temperature is blown into from hot-wind inlet (2), pass through end layer hot blast introducing port (10) through inner core, enter annulus, see through the end layer successively ... three layers, two layers, the orifice plate of one deck, contact with the material flow of beating, with its water evaporates and take away, discharge by exhaust outlet (3) at last.

Change the setting angle or the vibrating motor eccentric block angle of vibrating motor, can change the amplitude of body, thereby change material flow.

The utility model is except that the advantage with general vibrating dryer, owing to adopt the multilayer orifice plate, material and hot blast adverse current make hot blast repeatedly contact with material, and the low material of the hot blast contacting hydrous amount of elder generation, makes its oven dry.Give the high material preheating of water content again, heat is fully used.So heat energy utilization rate height, and floor space is little.The utility model is equipped with feed bin at one deck feeding mouth place, and with mobilizable gate control feeding coal, thereby the purpose that reaches the homogeneous feed can be saved a feeding device.

The utility model adopts two vibrating motor excitings, make material flow along ring-shaped orifice plate do the horizontal vaults campaign.Make material obtain the oven dry of homogeneous, and the material table surface wear is little, the material that some surface quality are had relatively high expectations (as monosodium glutamate) is more suitable especially.

The eccentric block angle of the used vibrating motor of the utility model or the setting angle of vibrating motor all can be adjusted.In order to the amplitude of adjustment machine, thereby adjust material flow, make machine applied widely, and simple in structure, easy to adjust.
