Description

Technical Field

[0001] The utility model relates to the technical field of spray dryers, in particular to a closed spray dryer with a filtering mechanism. Background Art

[0002] Spray dryer is a device that can complete drying and granulation at the same time. According to the process requirements, the pressure, flow rate and size of the spray hole of the liquid pump can be adjusted to obtain the required spherical particles of a certain size ratio. Spray dryer is a kind of continuous atmospheric pressure dryer. The liquid material is sprayed into mist with special equipment so that it can be dried by contact with hot air. Spray dryer usually atomizes the liquid through atomizing nozzle. If the atomized liquid is mixed with impurities, it will affect the drying efficiency during the drying process and consume more heat, so it is necessary to filter the liquid before spraying.

A discharge port 26 interconnected with the ring shell 25 is opened on the left side of the ring shell 25. A discharge pipe 27 interconnected with the ring shell 25 is fixedly connected to the bottom of the partition 22. The bottom end of the discharge pipe 27 penetrates the ring shell 25 and extends to the inside thereof. The discharge pipe 2 7 is provided with a solenoid valve, an annular plate 28 is fixedly connected to the bottom of the partition 22 and located on the surface of the annular shell 25, and adjusting blocks 29 are fixedly connected to the tops of the left and right sides of the annular shell 25. The side of the adjusting block 29 close to the annular plate 28 is in rotational contact with the annular plate 28, and the bottom of the adjusting block 29 is fixedly connected with a rotating block 210. The annular plate 28 is provided with an annular groove 211 used in conjunction with the two rotating blocks 210. The bottom of the rotating block 210 penetrates the annular groove 211 and extends to the inside thereof and is in rotational contact with the inner wall of the annular groove 211. By arranging the mutual cooperation of the annular plate 28, the adjusting block 29, the rotating block 210 and the annular groove 211, the stability of the annular shell 25 during movement is ensured.

[0024] Furthermore, the control methods of the servo motor 24 and the solenoid valve on the discharge pipe 27 are all controlled by an external controller matched therewith, and the control circuit can be implemented by simple programming by technicians in this field. This is common knowledge in this field and will not be elaborated on here.

[0025] Furthermore, a transparent observation window is provided on the front of the connection shell 21 , so as to facilitate observation of the internal conditions of the connection shell 21 .

[0026] The filter disassembly and assembly mechanism 3 is arranged on the connection shell 21. The filter disassembly and assembly mechanism 3 includes a pull block 31. The number of the pull blocks 31 is two and they are respectively arranged on the left and right sides of the connection shell 21. The side of the pull block 31 close to the connection shell 21 is in contact with the connection shell 21. The side of the pull block 31 close to the top block 23 is fixedly connected with a filter screen 32. The side of the filter screen 32 close to the connection shell 21 penetrates the connection shell 21 and extends into the interior thereof. The side of the filter screen 32 close to the inner wall of the connection shell 21 is in contact with the inner wall of the connection shell 21. The filter screen 32 is in contact with the top block 23 on one side thereof, and the filter screen 32 is fixedly connected with an iron block 33 on the other side thereof away from the pulling block 31. Slots 34 are provided on the left and right sides of the top block 23. The side of the iron block 33 close to the slot 34 passes through the slot 34 and extends into the interior thereof. A magnet 35 which is attracted to the iron block 33 is fixedly connected to the inner wall of the slot 34. A material extraction pump 36 is fixedly connected to the top of the left side of the machine body 1, and a material suction pipe 37 which is interconnected with the connecting shell 21 is fixedly connected to the top of the material extraction pump 36.

[0027] Specifically, when the filter screen 32 on the left side needs to be removed, the direction of the discharge port 26 is made to face right, and then the pull block 31 is pulled to the left. The pull block 31 drives the filter screen 32 to move to the left, so that the filter screen 32 drives the iron block 33 to separate from the slot 34 and the magnet 35 respectively, and the filter screen 32 on the left side can be pulled out of the connecting shell 21.

[0028] By connecting the shell 21, the partition 22, the top block 23, the servo motor 24, the annular shell 25, the discharge port 26, the discharge pipe 27, the annular plate 28, the adjustment block 29, the rotating block 210, the annular groove 211, the pulling block 31, the filter screen 32, the iron block 33, the slot 34, the magnet 35, the material pump 36 and the suction pipe 37, it is convenient to filter the liquid to be processed and filter out its impurities. When the filter screen 32 is blocked and needs to be disassembled for cleaning, the liquid can no longer be filtered, thereby avoiding affecting the efficiency of the liquid drying process. It is also convenient to disassemble the filter screen 32 for cleaning and maintenance, thereby improving flexibility during use.

[0029] When in use, open the feeding cover to discharge the processed liquid into the connecting shell 21 and on the partition 22, then open the solenoid valve on the discharge pipe 27, so that the liquid is discharged into the annular shell 25 through the discharge pipe 27, and the liquid is filtered through the filter screen 32 on the left through the discharge port 26, and then discharged into the body 1 through the suction pump 36 for atomization and spraying. When the filter screen 32 on the left is blocked, start the servo motor 24, and the servo motor 24 drives the annular shell 25 to rotate 180 degrees through the output shaft, so that the liquid is filtered by the filter screen 32 on the right through the discharge port 26.

[0030] In summary: the closed spray dryer with a filtering mechanism solves the problems raised in the above-mentioned background technology by the mutual cooperation of the connecting shell 21, the partition 22, the top block 23, the servo motor 24, the annular shell 25, the discharge port 26, the discharge pipe 27, the annular plate 28, the adjustment block 29, the rotating block 210, the annular groove 211, the pulling block 31, the filter screen 32, the iron block 33, the slot 34, the magnet 35, the extraction pump 36 and the suction pipe 37.
