Abstract
The utility model relates to a pressure-flow type air spray drying device which adopts a pressure type air feeding device and a pressure-flow type air nozzle. The utility model replaces a reciprocating type plunger pump with a pressure type air trough, and replaces the pressure type air nozzle with the pressure-flow type air nozzle. The material current goes into a tapered inner cavity of the nozzle from the side of the nozzle under the condition of pressurization, forming a tapered high-speed rotary liquid membrane, and spurts out with high pressure air flow which goes through the straight tube of the middle of the nozzle at the verge of the mouth of the nozzle. The utility model has the advantages of low power consumption, stable pressure of the material through the nozzle, equal and stable flow rate which can be control easily, non-easy blocked, good atomisation performance, non-easy drop and collapse, high recovery rate of the material, simple processing technology and operation and convenient maintenance.
Description
The utility model relates to a kind of drying device of chemical products.
The drying of the chemical products of large batch of fine powder type has been introduced a kind of more typical spray dry process in junior college's chemical industry teaching material, And is adopted by many units.This spray-drying installation adopts air flow type jet nozzle, after material is sent to nozzle atomization by reciprocating plunger pump, along with thermal current forward flows out from dry cat head, enters the product gatherer again.Because the pulsed that the reciprocating plunger pump motion forms changes, pressure oscillation is big, and flow is difficult to regulate, and air flow type jet nozzle, air supply consumption is big, and atomization is undesirable, and the material tower phenomenon that falls is serious, again because the air flow type jet nozzle annular space is narrow, material pump and nozzle also are easy to result in blockage, and continuous production is restricted, and operating difficulties, maintenance is inconvenient, and power consumption is big.
The purpose of this utility model is that a kind of material that enters nozzle will be provided, pressure stability, and flow can be controlled arbitrarily and be uniform and stable, and atomization is good, is difficult for falling tower and obstruction, can be used alternatingly the device of continuous drying.
The purpose of this utility model is achieved like this: replace reciprocating plunger pump And to be equipped with the middle trough of two Totally-enclosed-types by the vapour-pressure type chute feeder, after slip flows into the vapour-pressure type chute feeder, with compressed air the slip in the hopper is pressed into middle trough, pressurized slip high speed flow nozzle is atomized.And is because the air pressure in the dry tower---and air flow type jet nozzle replaces air flow type jet nozzle, material liquid stream material inlet from the nozzle side under the pressurization situation enters thorax in the nozzle, translot on pulverizer plate, form the liquid film of rotation at a high speed, the high pressure draught after evenly-distributed air holes on the air dispenser sleeve is regulated that enters with straight tube compressed air inlet in the middle of nozzle on the jet hole border sprays, and carries out drying in drying tower.Two middle troughs can be used alternatingly, thereby guarantee dry carrying out continuously, and enter the slip pressure stability of nozzle, and flow can be regulated uniform and stable arbitrarily, and nozzle is difficult for stopping up, and atomizing effect is good, is difficult for falling tower.
The embodiment of the utility model in conjunction with the accompanying drawings is described in further detail:
Fig. 1 air pressure---pneumatic spray drying device schematic diagram;
Fig. 2 air pressure---air flow type jet nozzle generalized section;
Fig. 3 air pressure---air flow type jet nozzle A-A generalized section.
As shown in Figure 1, device of the present utility model, when the material in the grog groove (1) after plate and frame type filter-press (2) dehydration, enter hopper (3), after dehydrated material in the hopper (3) is put into twin shaft change-can mixer (4) pulp, send into vapour-pressure type chute feeder (5), vapour-pressure type chute feeder (5) communicates with compressed air, with compressed air the material in the chute feeder is pressed into middle trough (6), middle trough (6) the And that also communicates with compressed air is equipped with atmospheric valve (22), pressurized material high speed flow nozzle (7) in the middle trough (6), in drying tower (8), carry out atomization drying,, blow by air blast (10) to the combustion furnace (9) of drying tower (8) supply hot-air, material in nozzle (7) after the atomizing, along with thermal current forward from drying tower (8) top outflow, enter roto-clone separator (11), the material after the separation with
Under the effect of the air-introduced machine (13) that filter (12) is connected, enter in the bag hose (12), collect product.
As shown in Figure 2, air pressure of the present utility model---air flow type jet nozzle (7) comprising: be fixed on the base (14) in the drying tower (8), air dispenser sleeve (15) and pulverizer plate (16), material inlet (20) on the base (14) is connected with middle trough (6), and compressed air inlet (19) is connected with compressed air stream.Have the middle compressed air inlet (19) of evenly-distributed air holes (21) and base (14) to communicate on the air dispenser sleeve (15), air dispenser sleeve (15) is in aggregates with being threaded with base (14).
As shown in Figure 3, the translot (18) that communicates with material inlet (20) and jet hole (17) inner chamber is arranged on the pulverizer plate (16) of air pressure of the present utility model---air flow type jet nozzle (7), pulverizer plate (16) is whole to be threaded with base (14), jet hole (17) inner chamber on the pulverizer plate (16) is tapered or spherical, and translot (18) enters the inner chamber of jet hole (17) from tangential direction.
The utility model has the following advantages compared to existing technology: replaced reciprocating plunger pump And by vapour-pressure type feeding groove and be furnished with two middle troughs, material pump that the impact because of raw meal particle size causes and the obstruction of nozzle have been avoided, two middle troughs can be used alternatingly, and production can be carried out continuously, has improved work efficiency, the material pressure that enters nozzle is stable, flow also can be controlled arbitrarily and be uniform and stable, and technology and operation are all easier, easy to maintenance. Adopt air pressure---air flow type jet nozzle, avoided again causing nozzle to stop up because the air flow type jet nozzle annular space is narrow. This device atomization is good and stable, and material is difficult for falling tower in drying tower, and the product recovery rate height has reduced cost, and the processing simple process, keeps conveniently.
