Description
Technical Field
The invention belongs to the technical field of medicine drying equipment, and particularly relates to drying equipment with an inner wall removing function for medicine production.
Background
The spray dryer is a device, is mainly used for drying products and separating and recovering the products, is suitable for continuous large-scale production, has high drying speed, and is mainly suitable for thermosensitive materials, biological products and pharmaceutical products. The working principle is that the raw material is placed in the middle of the top of a spray drying device, and then centrifugally atomized into tiny droplets through the high-speed rotation of an atomizing disc, hot air is introduced into the top of a drying tower, feed liquid is simultaneously sent to the top of the tower, and atomized droplets are sprayed through an atomizer, the surface area of the droplet groups is very large, moisture is rapidly evaporated after the droplet groups are contacted with the high-temperature hot air, the droplets become dry powder within a very short time, the temperature is remarkably reduced after the hot air discharged from the bottom of the drying tower is contacted with the droplets, the humidity is increased, the droplets are taken out as waste gas by an exhaust fan, and particles carried in the waste gas are recovered by a separation device; the powder is separated and collected by a cyclone as the drying air flows out of the bottom of the spray drying apparatus.
At present, more spray dryers in China are internally provided with blowing devices, and the aim is to blow powder stuck on the inner wall of spray drying equipment in the drying process. The blowing rod in the blowing device is a stainless steel pipe with a certain inner diameter, a small hole is formed in the pipe wall, compressed air is discharged through the small hole of the blowing rod in the rotating process of the blowing rod along the inner wall of the spray drying equipment, and powder on the inner wall of the spray drying equipment is blown away.
The above purge device has the following problems:
1. the drying air temperature in the spray drying equipment is higher, though be equipped with and sweep the device, still there is a small amount of powder can be adhered to on the inner wall, and can constantly increase on the inner wall along with the accumulation of time, sweeps the effect variation, finally sweeps and loses the effect.
2. The inner wall that sweeps the device and rotate along spray drying equipment always, sweep except that the aperture on the pole, other positions can the adhesion powder because of being in for a long time in the space that has the powder, long-time back, sweep and attach to a large amount of powders on the pole, collide and rub until the powder diameter is big to the inner wall with spray drying equipment, sweep the pole because of the powder weight increase, and with spray drying equipment's inner wall friction, the resistance increases and leads to sweeping the pole and warp and bend.
The improvement to the two problems of the absence of a purge mechanism is made as in patent application No. 201510973133.1; however, the following problems still remain:
first, the cleaned brush will have a new structure for accumulating powder, and the same cleaning problems exist.
Secondly, the brush contacts with the inner wall all the time in drying equipment, can abrade the inner wall, and the wearing and tearing cause the material of inner wall itself to fall into in the medicine, reduce the quality of medicine.
Thirdly, the brush is worn and loses the cleaning function.
The invention designs a drying device with an inner wall cleaning function for drug production by combining the existing sweeping mechanism mainly based on blowing and the structure mainly based on contact of patents, and solves the problems in the prior art.
