Below in conjunction with accompanying drawing and preferred embodiment, to a kind of its specific embodiment of Chinese medical spray drying tower, structure, feature and the effect thereof that foundation the present invention proposes, describe in detail as after.
See also Fig. 1 to shown in Figure 5, a kind of Chinese medical spray drying tower of preferred embodiment of the present invention, it mainly comprises tower body 2, public attention, shower nozzle, air-brush, reductor, hot blast part, air-outlet part, feed liquid part, wherein: tower body 2 comprises the cylindrical shell on top and the cone of bottom, tower body 2 peripheries are chucks 1, the top of tower body is provided with public attention 3, the central authorities of public attention 3 are provided with shower nozzle 5, also has symmetrically arranged whirlwind case 4 on public attention 3, also be provided with hot-wind inlet 23 on public attention 3, this inlet is connected with warm-air pipe 6; The bottom of tower body 2 is provided with air-brush casing 11, is provided with the air-brush umbrella wheel 10 that reductor 8 drives in the air-brush casing 11, and being fixed with on this air-brush umbrella wheel 10 can be with the air-brush pipe 9,12 of umbrella wheel rotation; The bottom of tower body 2 connects a discharge pipe 13, and discharge pipe 13 is connected with cyclone 15, and the cyclone bottom is provided with and connects powder bucket 16.
As Fig. 1, Fig. 3 and shown in Figure 4, the top of tower body 2 is provided with the whirlwind case 4 of 6 symmetries, whirlwind case 4 is on 6 cuboids that are welded on public attention, cuboid top is welded with ring flange 27, be mounted with wind direction board 30 on the whirlwind case 4, hot blast enters public attention 3 from the tower body top with tangential direction, and the size of wind speed, direction are regulated by 6 wind direction boards 30, the purpose of regulating wind direction is that hot blast is concentrated on central point to depressing to umbrella fog from the tower body top, and it is monolateral that spraying can be partial to.
The fixedly axillare 28 of whirlwind case 4, direction plate centration axis 29 and 30 3 parts of wind direction board weld together, and fixedly axillare 28 is clipped between upper flange plate 25 and the middle ring flange 26, the hole during direction plate centration axis 29 is passed on ring flange 26 and the deep bead 33.Wind direction board 30 is positioned at the bottom of direction plate centration axis 29, at first its two parts are welded together, put into whirlwind case 4 and public attention 3, deep bead is inserted in the wind direction board centration axis 29 then, and deep bead is welded on public attention 3, with middle ring flange 26, fixedly axillare 28 is inserted in the wind direction board centration axis 29, fixedly axillare 28 is welded together with wind direction board centration axis 29 at last again. Ring flange 25,26,27 is fixedly connected by bolt 31, nut 32.
The step of adjusting wind direction board 30 is: unclamp spiral shell inspection 31, take off ring flange 27, rotational fixation axillare 28 is to the needs position then, determine the position of wind direction board 30 after, with ring flange 26 and fixedly axillare 28 clampings of ring flange 27, be fixed by bolt 31, nut 32.Shown in Fig. 1,5, air-brush pipe 9,12 is installed in the bottom of tower body 2, air-brush pipe 9 by air-brush pipe I, reducing head I, air-brush pipe II, reducing head II, air-brush pipe III, reducing head III, and the acute pipe of gas IV be linked in sequence and form, thick upper end, its lower end carefully, air-brush pipe 9 be sealing shroud 43 bottom.Perforation connects an arm 42 on the tube wall of air-brush pipe I, and this arm 42 is provided with movable joint 41, and the other end of arm 42 connects bottom air-brush pipe 12.
Shown in Fig. 1,5, fixing initiatively umbrella wheel on the speed reducer output shaft, this umbrella wheel drives the passive air-brush umbrella wheel 10 that is fixed on the air-brush pipe 9, and the top, hole that air-brush pipe 9 passes tower body 2 bottoms and air-brush casing 11 bottoms is equipped with seal and sealing shroud 43.
The course of work of air-brush pipe 9,12 is: start reductor 8, by air-brush casing 11, air-brush umbrella wheel 10 air-brush pipe 9,12 is rotated in tower body 2, its speed is 10 commentaries on classics/min.Gas enters in the pipe from bottom air pipe 19 in the air-brush pipe, and air-brush pipe 9 is used for spary tower wall, in order to avoid dry powder concentrates at the tower wall, forms carbonization.Simultaneously, also be provided with base air-brush pipe 12, to prevent the rapid integrated dead angle of dust in the bottom of tower body 2.After operation finishes, enter in the air-brush pipe carrying out automatic spin rinse in the tower from wash tub pipe 20 diversions.
Existing spray drying tower is because the import hot blast is about 180 ℃, so the tower wall temperature is also about 160 ℃, in order not scald the people, generally adopt aluminium silicate wool insulation pack wall, and the high-temperature of inwall part Chinese medicine is dusted after saccharification again, be bonded in Ta Bishang, form carbonization.
Drying tower of the present invention all is provided with chuck from top cylindrical shell and bottom cone, and be provided with suction opeing 18 at upper shell, flange in the bottom is provided with air inlet 17, its objective is to allow cold wind enter, extract out from top suction opeing 18 then, get rid of hot blast from air inlet 17, promptly reduced the tower wall temperature, make it to remain on about 80 ℃, make the temperature that keeps dry in the tower, avoid the medicinal powder carbonization.
In addition, the crux of dry processing tower is the cylinder roundness of tower body cylindrical portion, can normally move in order to guarantee the air-brush pipe, necessarily require the not super 10mm error of its circularity Φ 300mm, for reaching above-mentioned requirements, can use the mold typing method to carry out processing and fabricating, make it guarantee circularity.Mold is to be welded with the interior external diameter of some band steels according to cylindrical shell.When assembling drying tower of the present invention, the top cylindrical shell is inserted into from special mold top, the bottom cone is pushed into by the mold bottom, then welding.Like this, guaranteed the circularity of cylindrical shell.Another effect of mold, during installation, mold is supported on the steel platform as support ring.Because barrel diameter is big, for guaranteeing its circularity, is provided with 3-4 stiffening ring in the cylindrical shell chuck.
In sum, hot blast enters public attention by warm-air pipe 6 with tangential direction, and the size of wind speed, direction are regulated by 6 air regulating boards 22.
The Chinese medicine feed liquid is delivered to shower nozzle 5 by feed pipe, and sprinkler pressure is 6-7kg/m
2, feed liquid is high speed centrifugation therein, and atomizing mixes with hot blast and carries out promptly being dried after the heat exchange.
Dry powder is by discharge pipe 13, cyclone 15, enters to connect powder and disclose 16, and flushing hole 14 is to be used for Rapid Cleaning discharge pipe inside
Air-brush pipe 9 rotates in tower body with the speed of 10 commentaries on classics/min, and spary tower wall is in order to avoid dry powder is assembled.Another air-brush pipe 12 is the bottom sparies to tower, to prevent the rapid integrated dead angle of dust.After operation finishes, enter in the air-brush pipe carrying out automatic spin rinse in the tower from wash tub pipe 20 diversions.
Chuck has ventilation function, from tower body bottom air inlet mouth 17 air intakes, from 18 air-out of top suction opeing, reaches the cooling purpose to the tower wall.
The technological innovation of a kind of Chinese medical spray drying tower of the present invention that above-mentioned structure like this constitutes all has many saving graces for technical staff of the same trade now, and the progressive that possesses skills really.The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified to the equivalent embodiment of equivalent variations, but every technical solution of the present invention content that do not break away from,, all still belong in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did according to technical spirit of the present invention.
