Abstract
The utility model relates to a cross flow type multilayer disc drier. A plurality of layers of hollow drying discs are arranged in a machine shell of the cross flow type multilayer disc drier along a main shaft from top to bottom. Rake arms are arranged on the discs, and rake teeth are arranged on the rake arms. The periphery of an external material disc is connected with the machine shell into a sealed type. Air in the drier blocked by the machine shell at the external edge of the external material disc flows back to the center part and flows to a contiguous internal material disc along the main shaft. As intervals between the internal edge of the internal material disc and the main shaft are quite small, air is forced to flow to large intervals between the external edge of the internal material disc and the machine shell. Thus, the air flows to a contiguous external material disc. Therefore, the air with steam revolves layer by layer in a stagger way and is exhausted by and air outlet. The utility model avoids the problem of short circuit of air in the machine shell, accelerates drying speed, increases the utilization ratio of heat medium and reduces cost.
Description
The utility model belongs to hot conductive drying machine, is specially adapted to the drying of powder or granule wet stock.
The general at present powder or granule drying machine that uses has hot air convection formula and hot conduction-type.Hot conduction-type divides oscillatory type and rake formula again, and rake type drier is because heated surface area is limited, and the bed of material is thick, causes drying time long, and heat utilization efficiency is not high yet.According to the disclosed multi-layer discs drying machine of Chinese patent literature, basin is improved to vertical multilayer, increase heating surface area, thereby improve the thermal efficiency.But because dry disk border is not connected with casing, just form vertical open space in the body, the air that enters in the body can unimpededly flow along the space of disk and casing, causes air fully the steam that evaporates not to be taken away, and reduces heat utilization efficiency.For improving the rate of drying exhaust air rate of just having to strengthen, both wasted energy, also increase Dust Capacity, certainly will increase the investment of supporting cleaner.
The purpose of this utility model is to overcome the deficiency that has the multi-layer discs drying machine now, and a kind of thermal efficiency height is provided, and dust is low, invests little cross-current type multi-layer discs drying machine.
This practical being achieved in that
A kind of cross-current type multi-layer discs drying machine, by casing, material advances, outlet, thermal medium advances, outlet, the air port, main shaft, dry disk, the rake arm, formations such as drive motors, the dry charging tray of a plurality of hollow rings is alternate with the main shaft axially-aligned by inside and outside charging tray, interior charging tray periphery links into an integrated entity with casing, outer charging tray is fixed on the casing inner wall by connecting plate, is provided with level rake arm with each disk corresponding height place on main shaft, which is provided with a plurality of and the rake teeth that radially becomes angle, rake teeth angle direction on the adjacent two layers charging tray is opposite, and rake teeth becomes the 35-50 degree with the charging tray surface radius.Each disk and the housing that is fixed thereon form an individual components, and housing is connected by flange between the adjacent discs.
The utility model is described in further detail below in conjunction with accompanying drawing:
Accompanying drawing is a structural representation of the present utility model
1-motor, reductor, the 2-main shaft, 4-harrows arm, charging tray in the 5-, 6-rake teeth, the outer charging tray of 7-, 8-casing, the import of 9-thermal medium, 3, the 10-air port, 11-feed opening, 12-charging aperture, the outlet of 13-thermal medium, 14-flange.
Accompanying drawing is a cylindrical shape drying machine, and main shaft 2 connects full machine from top to bottom, and top is connected with motor, reductor 1, and the centre is provided with the several layers charging tray.The drying machine top has charging aperture 12, air port 3, and the bottom has feed opening 11, air port 10.Charging tray 5 and outer charging tray 7 in charging tray is divided into, charging tray is the middle annular hollow charging tray that the chuck space is arranged, so that thermal medium can be fed wherein by import 9.Charging tray is alternate inside and outside several is enclosed within on the main shaft 2, arranges from top to bottom.The spacing of interior charging tray 5 inner edges and main shaft 2 is bigger, is beneficial to gas communication and material moves down, and its outer and casing 8 connect into closed, pass through thus with barrier gas; Outer charging tray 7 diameters are slightly less than interior charging tray 5, are fixed on the casing inner wall by connecting plate, and its inner rim is near main shaft 2, but do not contact, and the outer is bigger apart from the casing spacing, are convenient to gas communication and material moves down.Each charging tray is a separate part together with its casing that adheres to, and is connected by the flange on the casing outer wall 14 between each separate part, is convenient to install, operate, and can combines the different numbers of plies as required.According to differences such as the water content of material to be dried, granular size, drying time, thermal mediums, select suitable rotating speed, different number of plies dried feed dishes are set.
At the corresponding suitable height of main shaft loading plate, along continuous straight runs is provided with horizontal rake arm 4, and installation activity rake teeth 6 on the rake arm is about to rake teeth and is socketed on the rake arm not stuckly, makes it and can freely swing along the rake arm.Size, a material material size and quantity etc. according to dish are different, and the number of fingers of setting can be different.Rake teeth on the outer charging tray becomes miter angle with charging tray surface radius direction, the rake teeth direction of interior charging tray opposite with it with radially become 135 the degree.
Open motor, drive reductor 1 work, main shaft 2 rotates, and drives the rake arm that is installed on the main shaft and rotates.Wet stock is evenly added continuously by charging aperture 12, and movable rake teeth 6 one sides on the rake arm 4 constantly disperse wet stock, wipe off, make it to stir, be heated evenly, and promote wet stock on the other hand and down transfer.Because rake teeth 6 angles on the interior charging tray 5 are inside, material is inwardly transferred, and when surpassing the charging tray inner edge, promptly falls into down in the outer charging tray of one deck; The angle of rake teeth is outside on the outer charging tray 7, and material is outwards transferred, and when surpassing the charging tray outer, promptly falls into down in the interior charging tray of one deck.And the like, material is transplanted on the bottom charging tray from level to level, through feed opening 11 outputs.The heat medium vapours enters into charging tray chuck space by the thermal medium import 9 at each charging tray edge, the baking wet stock.The steam that gives out of baking flows on charging tray with the air of air port suction, is subjected to stopping of casing in interior charging tray outer rim and is back to the centre, outside main shaft flow to adjacent layer on the charging tray; Because outer charging tray inner edge and gap of main reinforcement are minimum, are unfavorable for the circulation of air, air is forced to flow to space bigger between outer charging tray outer and the casing, flows into thus on the adjacent interior charging tray.Like this, air is being carried steam secretly, and the cross-flow of circling round is from level to level discharged by the air port at last, and the water vapour that each layer evaporated is taken away fully, thereby solves the problem of air at the cylindrical shell internal short-circuit, improves the utilization rate of thermal medium, reduces cost.
