Abstract
The utility model relates to a fluidized granulating stove. The technical characteristic is that the bottom of a stove body forms an arc shape, and the upper part is an expansion joint. A spraying device uses pressure type breast-shaped nozzles, the nozzles are arranged in a concentric circle type, an air distributing device is fixed on an air distributing plate in a concentric circle type, air distributing holes are arranged on the side wall of an air distributing pipe, a conical cap is fixed on the air distributing pipe, and a side seam is arranged between the conical cap and the air distributing plate. The granulating stove has the advantages of simple structure, low cost, easy adjustment and maintenance, uniform gas distribution and favorable granulating effect, and can be widely used for industries, such as medicine, chemical industry, chemical fertilizer, foods, etc.
Description
The utility model belongs to a kind of fluidization granulation stove, particularly a kind of novel fluidization granulation stove of using in industries such as medicine, chemical industry, chemical fertilizer, food.
At present, the fluidization granulation stove that in industries such as medicine, chemical industry, chemical fertilizer, food, uses, its sprayer unit mainly adopts air flow type jet nozzle or usual pressure formula nozzle.The air flow type jet nozzle complex structure, the droplet of ejection is more tiny, forms more fine particle, and product granularity is little, and must be aided with air compressor and could work.Common pressure nozzle is easy to stop up, and is difficult for regulating, if not just do not install, drop also can occur and accumulate stream, causes boning between the particle, forms big agglomerate, even influences normally carrying out of granulation process.The more employing latasuture of distribution device in gas-fluid formula awl cap distribution grid, its deficiency are that awl cap resistance is big, cause the distribution grid pressure drop big, and power consumption is big; Also can't avoid simultaneously the dead band at equipment wall place, make its air-flow skewness, influence the granulation effect.
The purpose of this utility model is to overcome weak point of the prior art, and a kind of simple in structure, air-flow is evenly distributed, granulation is effective novel fluidization granulation stove is provided.
The purpose of this utility model can realize by following measure:
The structure of novel fluidization granulation stove is to install air inlet pipe (2) in the lower end of lower furnace body (1), and the upper end of lower furnace body is installing pneumatic panel (5) and upper furnace body (6).Circular arc is located to be in the bottom, lower end (7) of upper furnace body, is installing discharge nozzle (8) on the sidewall of lower end, and upper end (9) locate to be expansion joint, and the top is installing escape pipe (10) and feed pipe (13).The end that feed pipe stretches in the upper furnace body is installing sprayer unit (14).Installing air distributing device (15) on the pneumatic panel, air distributing device is concentric circles and arranges on pneumatic panel (5).
The structure of air distributing device (15) is to install gas-distribution pipe (16) on pneumatic panel (5), and air distribution hole (18) is arranged on the sidewall of gas-distribution pipe, and the top of gas-distribution pipe is installing awl cap (19), between awl cap bottom and the pneumatic panel latasuture (20) is arranged.
The structure of sprayer unit (14) is to install feed pipe (22) in the end of feed pipe (13), the end of feed pipe (22) is installing spray cone cover (23), the lower end of spray cap is installing spray plate (24), the breast-shaped jet nozzle of arranging by concentric circles (25) is arranged on the spray plate, and the bottom of breast-shaped jet nozzle has spray hole (26).
The utility model compared with prior art has following advantage:
1, sprayer unit adopts the pressure type breast-shaped jet nozzle, and is simple in structure, do not need auxiliary equipment such as air compressor just can work, and reduced equipment investment.The drop of nozzle ejection is bigger, and product granularity is good, and drop is difficult for accumulating stream, and is very favourable for granulation process.
2, air distributing device is given vent to anger by original gas-distribution pipe top and is changed the gas-distribution pipe sidewall into and give vent to anger, and has reduced awl cap resistance, and the pressure that greatly reduces distribution device in gas-fluid falls, thereby has also reduced power consumption.In addition, the latasuture of awl cap bottom is easy to regulate, so equipment debugging is very convenient.Air distributing device takes the concentric circles mode to arrange, and the dead band of having avoided air-flow to distribute fully is evenly distributed thereby can reach air-flow, improves the granulation effect.Whole distribution device in gas-fluid is a demountable structure, helps the maintenance of equipment.
3, the expansion joint structure is taked on the top of upper furnace body, air velocity is greatly reduced herein, thereby reduced carrying secretly of fine dust.
4, fluid bed is taked circular configuration, and different bed height upper sections are changed to some extent, can cause certain current gradient, makes the particle of different-grain diameter can both obtain uniform fluidization.Simultaneously, this fluid bed also has the more fine grain ability of preservation, helps the stable operation of granulation.
