Description
Technical field
The present invention relates to a kind of blow device, especially relate to a kind of blow device of spray drying device, belong to technical field of mechanical transmission.
Background technology
Spray drying device is used for chemical industry, pharmacy drying process, and raw material liq is dried to pressed powder.Its operation principle is placed on by raw material liq in the middle part of spray drying device top, transfer centrifugal atomizing through atomizing disk high-speed rotary again and become fine droplet, the dry air entered from spray drying device top side portion is dry and form powder to raw material liq, and powder flows out with dry air and to be separated through cyclone separator and to collect bottom spray drying device.
At present, domestic more spray drying device inside arranges and is all provided with blow device, its objective is and is purged by the powder sticked in dry run on spray drying device inwall.Blow device is made up of rotating mechanism, purging bar, compressed air system, purge the stainless steel tube that bar is certain internal diameter, tube wall there is the aperture of queueing discipline, purge bar rotate along spray drying device inwall and keep suitable distance with spray drying device inwall, compressed air is discharged by the aperture purging bar, is blown off by the powder on spray drying device inwall.
The blow device Problems existing of said structure:
1, the drying air temperature in spray drying device reaches more than 200 degrees Celsius, the long-time high temperature of inwall, although be provided with blow device, but still have a small amount of powder can stick on inwall, along with the prolongation of production time, on inwall, powder can constantly increase, cumulative, purge separating effect worse and worse, final purging is ineffective.
2, blow device rotates along the inwall of spray drying device always, all the time be in the environment of powder, except purging the aperture place of bar without powder, all there is powder adhesion at other positions purged on bar, along with the prolongation of time, the powder purged on bar is cumulative, final formation is to purge centered by bar, purge on bar and adhere to a large amount of powder, until diameier arrives greatly and the inwall of spray drying device is collided and rubs, purge bar because of powder weight strengthen, and with wall friction in spray drying device, resistance increase and cause purge bar distortion and bending.
Summary of the invention
The object of this invention is to provide a kind of blow device of spray drying device, the powder in spray drying device can thoroughly purge totally by this device, improves drying efficiency.
The present invention is achieved by the following technical programs:
A blow device for spray drying device, blow device is arranged on spray drying device inside; Blow device comprises purging bar, transmission mechanism, a pair hairbrush connecting rod, universal joint, supporting mechanism, compressed air; The shape purging bar is consistent with the inner surface contour of spray drying device, and the cylindrical purging bar is provided with several purge hole; The shape of hairbrush connecting rod is consistent with the inner surface contour of spray drying device, and the cylindrical of hairbrush connecting rod is provided with brush roll, the cylindrical of the brush roll of a pair hairbrush connecting rod, the purging cylindrical of bar, the tangent connection of inwall of spray drying device; Transmission mechanism comprises master gear and a pair driven gear, and master gear is arranged on the one end purging bar, and a pair driven gear is separately positioned on one end of a pair hairbrush connecting rod, master gear and a pair driven gear engagement; The flex point place purging bar and a pair hairbrush connecting rod is equipped with universal joint; The upper, middle and lower portion purging bar and a pair hairbrush connecting rod is equipped with supporting mechanism; The one end purging bar is connected with compressed air.
The present invention realizes by the following technical programs further:
The blow device of aforesaid a kind of spray drying device, the diameter of purge hole is less than the diameter purging bar.
The blow device of aforesaid a kind of spray drying device, purge hole aims at the inwall of spray drying device.
The blow device of aforesaid a kind of spray drying device, supporting mechanism is perpendicular with the axial direction purging bar and a pair hairbrush connecting rod.
The blow device of aforesaid a kind of spray drying device, brush roll rotates together with hairbrush connecting rod.
The present invention arranges a pair hairbrush connecting rod on purging bar, drives a pair hairbrush link rotatable by transmission mechanism, thus the dried powder purged on bar is cleaned down by brush roll on hairbrush connecting rod at any time.Due to inwall tangent of brush roll and spray drying device, brush roll while rotation also by clean for powder cleaning on spray drying device inwall.Because the outer fenestra of a pair brush roll is tangent, the powder be attached on brush roll is also cleaned along with the rotation of brush roll, and killing three birds with one stone, improves drying efficiency.This device is by transmission mechanism band electric brush link rotatable, and structure is simple to operation.
Advantage and disadvantage of the present invention, by for illustration and explanation for the non-limitative illustration passing through preferred embodiment below, these embodiments, only provide as an example with reference to accompanying drawing.
Accompanying drawing explanation
Fig. 1 is front view of the present invention;
Fig. 2 is top view of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in Figure 1 and Figure 2, blow device 1 is arranged on the inside of spray drying device 2; Blow device 1 comprises purging bar 3, transmission mechanism 4, a pair hairbrush connecting rod 5, universal joint 6, supporting mechanism 7, compressed air 8; The shape purging bar 3 is consistent with inwall 21 profile of spray drying device 2, and the cylindrical purging bar 3 is provided with several purge hole 31, and purge hole 31 aims at the inwall 21 of spray drying device 2, and the diameter of purge hole 31 is less than the diameter purging bar 3; The shape of hairbrush connecting rod 5 is consistent with inwall 21 profile of spray drying device 2, and the cylindrical of hairbrush connecting rod 5 is provided with brush roll 51, the cylindrical of the brush roll 51 of a pair hairbrush connecting rod 5, the purging cylindrical of bar 3, the tangent connection of inwall 21 4 of spray drying device 2; Transmission mechanism 4 comprises master gear 41 and a pair driven gear 42, and master gear 41 is arranged on the one end purging bar 3, and a pair driven gear 42 is separately positioned on one end of a pair hairbrush connecting rod 5, and master gear 41 and a pair driven gear 42 engage; The flex point place purging bar 3 and a pair hairbrush connecting rod 5 is equipped with universal joint 6; The upper, middle and lower portion purging bar 3 and a pair hairbrush connecting rod 5 is equipped with supporting mechanism 7, and supporting mechanism 7 is perpendicular with the axial direction purging bar 3 and a pair hairbrush connecting rod 5; The one end purging bar 3 is connected with compressed air 8.
Start compressed air 8 and transmission mechanism 4, master gear 41 drives purging bar 3 to rotate, compressed air 8 is by discharging in the purge hole 31 of purging bar 3, compressed air 8 blows on the inwall 21 of spray drying device 2 along with purging the rotation of bar 3, powder on the inwall 21 of spray drying device 2 is purged clean, while master gear 41 rotates, a pair driven gear 42 is driven to rotate, a pair driven gear 42 drives a pair hairbrush connecting rod 5 to rotate, brush roll 51 follows hairbrush connecting rod 5 to rotate, because brush roll 51 is tangent with purging bar 3, the dried powder purged on bar 3 can be swept totally by brush roll 51 at any time, due to inwall 21 tangent of brush roll 51 and spray drying device 2, powder on spray drying device 2 inwall 21 also cleans clean by brush roll 51 while rotation, because the outer fenestra of a pair brush roll 51 is tangent, the powder be attached on brush roll 51 is also cleaned along with the rotation of brush roll 51, thus thoroughly the powder in spray drying device 2 is purged clean.
In addition to the implementation, the present invention can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of application claims.
