For this reason, need to carry out fluidisation to hot and humid sugared part.The application of vibrated fluidized bed fluidization technology on drying of sugar process for cooling:
Current domestic sugar refinery is on drying of sugar cooling technology, and the groove that shakes, the belt naturally cooling of adopting dry more, and this dry technology is more original, and equipment requirements is very long just can reach final drying of sugar cooling technology index request.Generally speaking this mode original, there is no that technology content, backwardness, floor space are large, weak effect, sanitary condition are bad, work under bad environment, maintenance of equipment amount is large.
Adopt vibra fluidized bed drying cooling granulated sugar advantage:
1, owing to adopting fluidization technology, drying of sugar good cooling results;
2, equipment fight area is little, when agreeing to treatment capacity, adopts vibratory liquefaction bed technique contrast traditional way, can shorten 1/5th of drying of sugar cooling length
3, due to the totally-enclosed working order of vibrated fluidized bed, ensure that granulated sugar is not contaminated in dry process for cooling, ensure that quality product;
4, because vibrated fluidized bed has Icing Sugar to collect recovery system, can by Icing Sugar Separation and Recovery from granulated sugar in drying of sugar process of cooling.Avoid flying upward of Icing Sugar everywhere, ensure that Working environment health.
5, vibrating fluidized bed technology: granulated sugar is under the acting in conjunction vibrating exciting force and wind, in boiling state in vibrating bed, ensure that the good contact condition of granulated sugar and wind, according to ventilated state (hot blast or cold wind), drying or cooling operation are carried out to granulated sugar.
The present invention does technological innovation on original vibrated fluidized bed:
1, vibrated fluidized bed sieve plate innovation:
Vibrated fluidized bed sieve plate has various ways, but is single layer structure.According to characteristic and the granulated sugar graininess of drying of sugar cooling, propose compound sieve plate structure, i.e. double deck screen plate structure, every layer of sieve plate plays a part different, bottom sieve plate plays strength support and the effect of cloth wind, and top layer sieve plate plays even fluidizing and under preventing granulated sugar from draining to bed effect.
2, sieve-plate structure form innovation:
Also do not have one to use 45 degree of staggered shell type orifice plates in drying of sugar cooling field, this constructional feature, can form Whirl deposite tank, and mixing of materials boiling state is good, under material not easily drains to bed.
3, granulated sugar diverting device innovation:
Because granulated sugar is in vibrated fluidized bed inner drying process of cooling, there is clustering phenomena sometimes, affect the productive rate of granulated sugar, in order to solve this phenomenon that may occur.Two kinds of devices are adopted to solve this problem:
A) fixing breaker plate structure.Breaker plate is arranged on away specific position in hopper, is disperseed by granulated sugar at this position breaker plate when there being the trend of conglomeration,
B) rotate dispersing device, the axle that thorniness is housed by driven by motor one rotates, by the granulated sugar Forced Dispersion of conglomeration.
As shown in figures 1 and 3, fluidized-bed of the present invention is composed as follows: vibrating motor 1, blast inlet 2, mainframe box 3, perforated board 4, shell type orifice plate 5, mainframe box upper cover 6, air outlet 7, walks hopper 8, is flexible coupling 9, view port 10, bracing frame 11, discharge port 12, and water port 13.Wherein vibrating motor produces exciting force.Blast inlet is blast inlet.Mainframe box distributes air quantity, makes regional obtain different air quantity.Macroporous plate supports aperture shell type orifice plate, as shown in Figure 2.Air blast carries out drying cooling by shell type orifice plate to material.Mainframe box upper cover is in order to closed mainframe box, makes air blast and air inducing produce positive/negative-pressure environment, prevents sugar from contacting with extraneous bacterium in fluidized state.The damp-heat air that dry materials process of cooling produces and powder are by induced draught system from then on air outlet extraction.Walk hopper be exactly white sugar material walk to expect region.Being flexible coupling is shake groove and upper cover are separated, and makes upper cover not join vibration.View port walks material situation for observing material.Bracing frame is for supporting upper cover housing.Discharge port makes material along discharge port discharge.Water port is the water port of cleaning.
Gas blower is connected with fluidized-bed main frame by pipeline, fluidized-bed main frame to be connected with main frame upper cover by being flexible coupling, main frame upper cover is connected with cyclonic separator by pipeline, cyclonic separator is connected with induced draft fan by pipeline, gas blower, induced draft fan are connected with frequency conversion tank by cable, and gas blower, induced draft fan are positioned over air filtration indoor.
Innovative approach:
One, well plate format is improved
Existing fluidized-bed uses straight hole type orifice plate mostly, and it is little that this orifice plate exists percentage of open area, easily leaks sugar, and aperture such as easily to block at the defect.My company has made improvement on existing basis, have employed the 45 degree of staggered shell type orifice plates (being called for short shell type orifice plate once) being different from straight hole type orifice plate, as shown in Figure 2.Shell type orifice plate is the orifice plate adopting the punching press of Novel punching technology to produce, its perforate direction with walk to expect that direction becomes two 45 degree of angles, poroid is shell type, size φ 5mm--8mm, highly 0.8mm--2mm.Natural wind can be formed through this orifice plate two with walk to expect that direction becomes the eddy flow wind-force of miter angle, it is better that material mixes boiling state under this wind-force, and due to vertical surface not having perforate, material not easily blocks, and under not easily draining to bed at tapping.
Two, frequency-conversion control cabinet is increased
Original fluidized-bed gas blower, induced draft fan are dc switch and control, and forced-and-induced draft fan air force mainly relies on control forced-and-induced draft fan air port pipeline size to realize physical control, and such design is unfavorable for accurate the control to air quantity, and is not easy to adjustment.My company adds frequency-conversion control cabinet on the original basis, by frequency transformer, quantifiable control is carried out to forced-and-induced draft fan power of motor, the benefit of this equipment is that the power of motor by frequency conversion tank shows walks the demand such as amount and state to forced-and-induced draft fan air quantity accurate adjustment to adapt to material, and operation is very simple.
The start and stop of original fluidized-bed vibrating motor control by dc switch, when vibrating motor power-off, vibrating motor does not work suddenly, causes fluidized-bed slowly to stop under original vibrational frequency, stand-by time is large compared with long and noise, causes very large impact to bed this body structure of body and environment.My company passes through to add XXX in frequency conversion tank, achieves and controls the brake of fluidized-bed.When fluidized-bed is shut down; vibrating motor supply electric current slowly reduces, complete power-off in 5s-8s, and the negative-phase sequence curent then suddenly adding 1s-2s makes vibrating motor reverse; under the effect of two amplitudes and the not identical power of frequency, make fluidized-bed stop vibration immediately, complete brake process.
Three, air filtering system is increased
The air blast wind regime that original fluidized-bed adopts is natural wind, along with country progressively improves the requirement of food sanitation, is that wind regime carries out drying to granulated sugar and has been difficult to be up to state standards with natural wind.For this reason, my company adds air filtering system on the original basis.
Air filtering system is the set of system of filtering that carried out disinfection by natural wind, and he is made up of air filter chamber (brick or shaped steel stainless steel is built), filtering net, ultraviolet disinfection lamp, ozonizer.Gas blower is placed in hermetic air filtration indoor, natural wind carries out primary filter through the filtering net be embedded on filtration chamber's wall, first filter after air sucked by gas blower after the Depth Filtration of ultraviolet disinfection lamp and ozonizer generates ozone and rouse as in fluidized-bed.
It is last it is noted that above embodiment is only in order to illustrate technical scheme of the present invention but not to be limited, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to technical scheme of the present invention or equivalent replacement, and these are revised or be equal to the spirit and scope that replacement also can not make amended technical scheme disengaging technical solution of the present invention.
