Abstract
Description
Technical Field
[0001] The utility model relates to the field of cleaning equipment, in particular to a purge cleaning device for a spray drying tower. Background Art
[0002] Spray drying equipment is mostly used in the drying process of biomedicine, Chinese patent medicine and chemical industry. Specifically, the working principle of spray drying equipment is: using high-speed rotation in the horizontal direction to give the solution centrifugal force, so that it is thrown out at high speed, and its corresponding trajectory is spiral. At the same time, the droplets fall under the gravity, and are dried by high-temperature air during the falling process to form powder. Further, the powder and dry air are separated by a cyclone separator and the dry powder is collected.
[0003] Existing cleaning methods mainly include manual active cleaning, manual disassembly cleaning, and external supply of a complete set of cleaning. Among them, manual active cleaning has low cleaning efficiency, and manual disassembly cleaning is only suitable for experimental small spray dryers. Manual high-pressure water gun cleaning will have cleaning dead corners due to cleaning angle problems, and requires a lot of manpower and material resources, increasing the safety risk to users. External supply of a complete cleaning system means that after the spray drying operation is completed, the atomizer is removed or the manhole is opened to insert the cleaning nozzle for cleaning. The atomizer is removed and the cleaning hose and nozzle are inserted to clean the inside of the tower through a water pump. At the same time, the cleaning height is controlled by controlling the length of the inserted cleaning hose, so as to clean the entire tower wall. There is a large randomness during cleaning, low efficiency, and a small amount of drug residue is easily left on the top of the tower, which causes corrosion of the inner wall. Utility Model Content

[0022] During the use of the purging and cleaning device for a spray drying tower, the cleaning cylinder 3 is first inserted into the drying tower body 1 through the cleaning port, and then the driving motor 13 is fixed to the top of the drying tower body 1. The bottom of the cleaning cylinder 3 is inserted into the sealed bearing 8 through the connecting pipe 7 and spliced with the water pipe 6. The water pump 4 is connected with the water pipe 6 and the cleaning box 5 through the water pipe, so that the cleaning liquid is introduced into the cleaning cylinder 3. The cleaning cylinder 3 then sprays the cleaning liquid on the inner wall of the drying tower body 1 through the nozzle 10 to soften the dust. Then, the driving motor 13 is started to drive the cleaning cylinder 3 to rotate. During the rotation of the cleaning cylinder 3, the cleaning brush 12 is driven to rotate. The cleaning brush 12 wipes the dust on the inner wall of the drying tower body 1.

At the same time, the nozzle 10 can be used to realize the steps of wiping and spraying clean water at the same time. When the cleaning cylinder 3 rotates, the spraying area of the nozzle 10 will be further increased, thereby avoiding the occurrence of cleaning dead corners and improving the cleaning efficiency. When the cleaning step is completed, the cleaning device can be taken out, and then the blower 15 of the air-drying device can be installed in the cleaning port to air-dry the interior of the drying tower body 1, thereby avoiding residual water stains in the interior of the drying tower body 1. The structural types of the driving motor 13 and the blower 15 in the utility model are not specifically limited. Conventional motors or fan equipment in the motor and fan fields can be used. When the drying tower body 1 does not need to be cleaned, the water pipe 6 and the cleaning device are taken out and the water port and the cleaning port are sealed through the sealing cover.
[0023] If the drive motor 13 is not installed firmly during installation, the equipment is prone to generate large vibrations when working, thereby generating large noise. In this embodiment, a motor shell 2 is provided on the outside of the drive motor 13, and a connecting shell 14 is provided at the bottom of the motor shell 2. An output port is provided on the connecting shell 14, and the drive motor 13 is installed in the motor shell 2. The delivery end of the drive motor 13 is perpendicular to the output port, and the connecting shell 14 is connected to the drying tower body 1 through a thread. Lifting handles are installed on both sides and the top of the motor shell 2. The drive motor 13 is installed in the motor shell 2, and the motor shell 2 protects the drive motor 13 to prevent the drive motor 13 from being contaminated with too much dust. By arranging lifting handles on multiple surfaces of the motor shell 2, multiple fulcrums are set on the motor shell 2, which is more convenient for lifting and carrying.

At the same time, a sealing rubber pad can be configured on the inner side of the mounting base 9 to ensure the sealing of the water inlet. The sealing of the external pipeline of the water pipe 6 is ensured by setting a connecting flange.
[0025] In order to avoid residual water stains in the drying tower body 1, in this embodiment, the air-drying device includes a mounting cover 16 and a blower 15. The blower 15 is fixedly installed in the mounting cover 16. The bottom of the mounting cover 16 is provided with an opening, and the top of the mounting cover 16 is provided with an air inlet. A lifting handle is installed on the top of the mounting cover 16. The mounting cover 16 is rotatably installed with the cleaning port through a thread, so that the blower 15 is installed in the drying tower body 1. The mounting cover 16 uses the lifting handle as a fulcrum during installation.
[0026] In this embodiment, the water tank includes a clean water tank 17 and a foam tank 18, and the clean water tank 17 and the foam tank 18 are both provided with injection holes.
