Abstract
The utility model relates to a bulk material drying apparatus with a circular vibration linear pushing device, composed of a blower, a heater, troughs and a housing. The troughs are vertically distributed in the housing in multilayer. Both ends of each trough are provided with shake mechanism. Both sides of each trough are respectively a surging tank and a negative pressure surging tank connected through the blower. The heater is arranged in the surging tank. A condenser is arranged in the negative pressure surging tank. The housing is made of insulation material. The utility model has the advantages of non-caking material, high drying speed and energy saving in the process of drying as well as compact structure and small occupation area.
Description
The utility model relates to the energy-saving drying unit of a kind of bulk material, particularly a kind of bulk material drying unit that has rocking movement.
Moisture content in the various bulk materials is the biggest obstacle of its long preservation, the problem as grain, industrial chemicals etc. all exists.The discharge of moisture content needs three conditions in the various materials: i.e. the low pressure on the displacement of temperature, humid air, material surface.Bulk material is owing to its conductivity of heat is bad, and gas permeability is bad, and existing various drying units are difficult to make it to possess above-mentioned three conditions, and volume is big, the cost height, and energy consumption is big, and in dry run, bulk material lumps easily.
The purpose of this utility model is to provide the bulk material drying unit of a kind of compact conformation, reduction oven dry cost, raising drying efficiency.
Concrete technical scheme is: it is made up of blower fan, heater, hopper and housing etc., hopper adopts on the multi-layer intercrossed up and down frame that is arranged in the housing, circular vibration linear feeding mechanism is equipped with at the two ends of hopper, the left and right sides of hopper is respectively malleation constant voltage case and negative pressure constant voltage case, malleation constant voltage case communicates with the outlet of blower fan, altogether heater is housed, negative pressure constant voltage case communicates with the inlet of blower fan, condenser is housed in it, feed appliance is arranged on the housing, under receiving hopper is arranged, housing can be made by insulation material.
Because the circular vibration linear feeding mechanism that adopt at the two ends of hopper, so bulk material on hopper with the feeding of throwing mode, avoided the caking of material, and make the material heating fully, evenly, flowing of hot blast becomes 90 to spend with the direction of motion of material, not only make the surperficial air pressure of material be lower than air pressure inside, finish the displacement of humid air, and heating is more abundant, interlaced arrangement is in housing about the hopper, make the material Zigzag type move, reduced the volume of drying unit,, and adopted hot air circulating system because housing adopts insulation material to make, so heat-energy losses is littler, therefore advantage of the present utility model embodies a concentrated reflection of the compact conformation on the volume, and energy consumption is low, and firing rate is fast, homogeneous heating, material aspect such as do not lump.
Below in conjunction with description of drawings preferred forms of the present utility model.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
Drying unit shown in Figure 1 is by the hopper kinematic system, and hot air circulating system and housing 15 are formed.Housing 15 is made by the insulation material sealing, and feeding funnel 5 is arranged in the top, and the even device 6 of material is housed in it, and there is receiving hopper 7 lower end of housing 15, and hopper 4,4 ' multilayer repeats to be interspersed in housing 15.
The hopper kinematic system by hopper 4,4 ', motor 1,1 ', driving gear 2,2 ', travelling gear 2A, 2A ' composition, driving gear 2,2 ' and travelling gear 2A, 2A ' is meshing with each other successively, by motor 1,1 ' drive, motor 1,1 ' employing stepless speed regulation mode is carried out speed governing, thus control gear rotating speed easily.Driving tooth is moving 2,2 ' on be fixed with power transmission shaft 3, power transmission shaft 3 and hopper 4,4 ' an end hinge connect, hopper 4,4 ' the other end link to each other with supporting seat 18 by spring 17, supporting seat 18 is fixed on the interior frame 16 of body, and power transmission shaft 3 has certain distance with rotary gear shaft.Its essence is a crank mechanism.Like this, motor rotation drive driving gear 2,2 ', thus drive hopper 4,4 ' an end move up and down, because the other end of hopper, makes hopper 4,4 ' generation shake for flexibly connecting, bulk material is just at hopper 4 like this, 4 ' on be the shape that looses and move ahead, the height of its parabolic and preceding line speed can realize with distance between driving gear 2,2 ' rotating shaft by regulating motor speed and power transmission shaft 3.Since motor 1,1 ' respectively drive the driving gear 2,2 of the circular vibration linear feeding mechanism of hopper 4,4 ' end ', and motor, 1,1 ' direction of rotation, thus hopper 4,4 ' direction of vibration also opposite, can realize the purpose of the catadioptric operation of material thus.Hopper 4,4 ' the bottom can be provided with porous (the big I in aperture is determined by material composition granule size).
The closed cycle system that hot air circulating system is made up of big air quantity low velocity wind machine 9, malleation constant voltage case (19), negative pressure constant voltage case 12 and some utilidors, malleation constant voltage case 19 communicates with the outlet of blower fan 9, its inner having heaters 10, negative pressure constant voltage case 12 communicates with the inlet of blower fan, there is condenser 11 its inside, hopper 4,4 ' the left and right sides damping sheet 20 is housed.The course of work of hot air circulating system is: air is blown in the malleation constant voltage case 19 by blower fan, is heated by heater 10 after damping sheet 20 flows through material with the material movement vertical direction, enters negative pressure constant voltage case 12 after taking away moisture content, through condenser.11 condensations, moisture content liquefaction back flows into water receiving tank 13, and the delayed heat air is drawn into fans entrance, thus recycling heat energy.The 8th, the motor of driving blower fan 9, the 14th, blower fan 9 air intake negative-pressure pipelines.
The whole motion process of bulk material in drying unit is: through the even device 6 of material, enter into the hopper of top layer by feeding port 5, material is in the diffusing formula fold return motion of hopper upthrow, move downward from level to level,, finish dry run after receiving hopper 7 flows out drying device.
