Technical field

The utility model belongs to sodium glutamate production equipment technical field, is specifically related to a kind of sodium glutamate oven dry fluid bed.

Background technology

Traditional sodium glutamate drying plant has belt drying equipment, drum dried equipment etc., but has disadvantage: on the one hand because of containing in the sodium glutamate crystal combines H ₂The O molecule loses when temperature is too high easily; On the other hand, after wet sodium glutamate crystal contacted with each other, the time was long more, was easy to generate more and crystalline substance, thereby required bake out temperature to be controlled at 50～80 ℃ and flash bakings.The present vibrated fluidized bed that uses mostly carries out drying to product, and the use of vibrated fluidized bed meets the dry specific (special) requirements of crystal to a certain extent, but the bigger rooms for promotion of existence that remain unchanged such as drying rate and effect, crystal grain outward appearance.

The utility model content

The technical problem that the utility model solves: a kind of sodium glutamate oven dry fluid bed is provided, utilizes hot blast, adopt the pneumatic vibration mode as power source; Avoided direct use electric energy; Reduced energy resource consumption, in the oscillating screen plate upper surface deep bead has been set simultaneously, changed hot blast and flow to; Improve drying efficiency dramatically, reduced the frequency of occurrences of product and crystalline substance, adhesion, big or small first-class outward appearance flaw.

The technical scheme that the utility model adopts: a kind of sodium glutamate oven dry fluid bed, have housing, lower horizontal is provided with the hot blast surge chamber that dividing plate is divided into housing the pneumatic conveying drying chamber and the bottom on top in the said housing; The two ends of said pneumatic conveying drying chamber are respectively equipped with charging aperture and discharging opening, and top is connected with tail wind gathering-device; Above the said dividing plate pneumatic vibrator unit is installed, the top of said pneumatic vibrator unit is provided with sieve plate, drives the sieve plate vibration through pneumatic vibrator unit; Said pneumatic vibrator unit air inlet is connected with hot air source, and exhaust outlet is communicated with the hot blast surge chamber through tail wind collecting pipe.

Wherein, Said pneumatic vibrator unit is made up of air motor and cam mechanism; Said air motor is fixed on the dividing plate, and the air inlet of said air motor is connected through motor blast pipe and hot air source, and exhaust outlet is communicated with the hot blast surge chamber through motor tail wind collecting pipe; The below that said air motor driving cam means, said cam mechanism are positioned at sieve plate promotes the sieve plate vibration.

Further, be uniformly distributed with deep bead on the upper surface of said sieve plate, and the spacing between adjacent two deep beads is 0.5-2cm, the angle between deep bead and the sieve plate is 20-60 °.

Further, said hot blast surge chamber is provided with the hot blast compensating port, and the hot blast compensating port is connected with hot air source.

The utility model advantage compared with prior art:

1, use hot blast simultaneously as the power source and the oven dry thermal source of vibrating mechanism, wind energy and heat energy are combined and fully utilizes, comprehensive utilization of energy rate height, energy-saving effect is remarkable;

2, realized the coordination control of vibration frequency and hot blast air quantity, easy and simple to handle; Hot blast air quantity make-up system is set simultaneously, convenient compensation oven dry hot blast consumption;

3, the oscillating screen plate of particular design can change the hot blast flow direction, has increased the time of contact of hot blast and crystal grain, has improved drying efficiency;

4, hot blast blows crystal grain and makes the crystal grain turbulization, thereby it is more thorough that crystal grain is disperseed, and has shortened crystal grain time of contact to each other, has effectively contained and the generation of brilliant phenomenon.

The specific embodiment

A kind of embodiment of the utility model is described below in conjunction with accompanying drawing 1,2,3.

A kind of sodium glutamate oven dry fluid bed has housing 15, and lower horizontal is provided with the hot blast surge chamber 4 that dividing plate 13 is divided into housing 15 the pneumatic conveying drying chamber 12 and the bottom on top in the said housing 15; The two ends of said pneumatic conveying drying chamber 12 are respectively equipped with charging aperture 1 and discharging opening 10, and top is connected with tail wind gathering-device 11; Above the said dividing plate 16 pneumatic vibrator unit 7 is installed; Said pneumatic vibrator unit 7 is made up of air motor 6 and cam mechanism 5; Said air motor 6 is fixed on the dividing plate 16, and the air inlet of said air motor 6 is connected through motor blast pipe 8 and hot air source, and exhaust outlet is communicated with hot blast surge chamber 4 through motor tail wind collecting pipe 9; The below that said air motor 6 driving cam means 5, said cam mechanism 5 are positioned at sieve plate 2 promotes sieve plate 2 vibrations.Said hot blast surge chamber 4 is provided with hot blast compensating port 3, and hot blast compensating port 3 is connected with hot air source.

Be uniformly distributed with deep bead 14 on the upper surface of said sieve plate 2, and the spacing between adjacent two deep beads 14 is 0.5-2cm, the angle between deep bead 14 and the sieve plate 2 is 20-60 °.Its effect is to change hot blast to flow to, and increases material-gas time of contact and the contact for a long time each other of minimizing crystal in the dry run, reduces and brilliant generation.

In the course of work, hot blast at first gets into air motor 6, and blast is changed into 2 vibrations of power drive sieve plate, and the frequency of sieve plate 2 vibrations is by the unlatching platform number and the control of blast size of air motor 6; Hot blast through air motor 6 gets into 4 collections of hot blast surge chamber; Dividing plate 13 from hot blast surge chamber 4 tops evenly is blown into pneumatic conveying drying chamber 9; And under the effect of the deep bead 14 that is uniformly distributed with in the upper surface of sieve plate 2; Change wind direction and blow crystal grain rotation and oven dry crystal grain, drying efficiency significantly improves; So that during the crystal grain finish-drying, to hot blast surge chamber 4, make blast stable and reach dry demand through hot blast compensation inlet 3 compensation air quantity when the blast deficiency, the waste gas that produces in the pneumatic conveying drying chamber 12 in the drying course is collected the back discharge by tail wind gathering-device 11.
