Description

Canyon formula vibration fluidizing drier

The utility model relates to a kind of fluidization drying apparatus, relates in particular to a kind of canyon formula oscillatory type fluidization drying apparatus.

Be used in the drying equipment of tobacco stem or leaf silk, mainly contain cut-tobacco drier and explosion puffing drying tower, but cut-tobacco drier is big to the broken rate of stem, leaf silk, and explosion puffing drying tower energy-output ratio is big, so there is a kind of advanced fluidization drying apparatus that utilizes the fluidized drying principle that stem, leaf silk are dried at present, this kind fluidization drying apparatus is not joined because of shell and is shaken, and complete machine intensity is better, simultaneously also reduce stem, leaf silk broken rate, and can improve drying efficiency.But the air compartment of this drying equipment all is arranged on the bottom of fluidized bed body, the bed body has many apertures to constitute, when hot blast at the bottom of the bed when bed body aperture blows afloat material, make material carry out the exchange of heat and mass, but because hot gas is to blow from the bottom up, after use a period of time, aperture on the bed body is under material and dust effect thereof, aperture is stopped up by material easily, and therefore making the drying efficiency instability influences drying efficiency.After material and bed dirt were fallen under the fluid bed through the aperture on the bed body simultaneously, cleaning is difficulty comparatively.

It is strong that the purpose of this utility model provides a kind of drying capacity, the drying efficiency height, and energy consumption is low, the canyon formula vibration fluidizing drier of compact conformation.

The utility model is the technical scheme that achieves the above object: a kind of canyon formula vibration fluidizing drier, have housing, hot blast chamber, hot air apparatus, the vibratory feed that constitutes by cell body, eccentric stiffener, equalizer bar, pull bar and frame, the eccentric stiffener that is contained on the frame is connected with cell body by pull bar, fixedly connected with equalizer bar with cell body respectively with its two ends of several forks that frame is hinged, it is characterized in that:

A, have at least plural independent hot blast chamber to be arranged on the top of vibratory feed, be installed in bottom, hot blast chamber on the leg and be connected with and be the vertical blower that has order to arrange, the bottom land of U type cell body has and the vertical corresponding projection of blower;

B, have at least plural independent hot air apparatus to be arranged on the below of vibratory feed, hot air apparatus is linked to each other to connect by blower fan, heat exchanger and warm-air pipe and constitutes, and warm-air pipe is communicated with hot blast chamber from each respectively;

The top of c, two baffle plates is fixedly connected on the left and right side of body frame respectively, the bottom of baffle plate is connected with U type cell body both sides by soft sealing strip, baffle plate, soft sealing strip, U type cell body and housing constitute hothouse, filter is housed in the hothouse, housing top is provided with return air chamber, one end of backwind tube is communicated with return air chamber separately, and the other end of backwind tube is connected with blower fan from each and communicates, and the humidity discharging pipe is housed on the return air chamber.

Beneficial effect after the employing technique scheme is: its hot blast chamber of canyon formula vibration fluidizing drier of the present utility model is arranged on the top of vibratory feed, and it is separate again, can dry the material in the hothouse separately, the bottom of hot blast chamber is connected with several vertical blowers that have order to arrange, the hot blast of hot blast chamber blows from top to bottom through vertical blower, the possibility of having avoided vertical blower to be stopped up by material, keep that air-flow is unblocked to be blown from top to bottom, drying efficiency is unaffected extremely eventually to the beginning, and vertical blower is orderly arrangement in hothouse, make material comparatively even in dry run, in the U type cell body bottom that is loaded with material, have with vertical blower and arrange several consistent small boss, the air-flow that blows out from vertical blower scatters along the small boss of U type cell body, blows to U type cell body bottom and is seeped in the material, carries out the exchange of sufficient heat and mass with material, so drying capacity is strong, dry efficient height.2, because separate hot blast chamber communicates with separately hot air apparatus, can control the temperature of each hot blast chamber according to the moist degree of material in the U type cell body, control operation makes things convenient for, and also avoids the waste of the energy.3, this fluidized drying machine has adopted air-returning device, make after filtration, enter blower fan once more after the humidity discharging, hot blast can be circulated, at utmost utilize return air through the hot-air behind the over-heat-exchanger, the return air utilization rate can reach about 80%, not only improved the thermal efficiency, but and energy savings, 4, the hot blast chamber is arranged on oscillating conveyor top, and hot air apparatus is arranged on the oscillating conveyor below, after adopting hot air circulation, make the hot-air system volume-diminished, entire equipment is very compact.
