The left end of the electric heating tank 4 is connected with a blower 8, and the input end of the blower 8 is installed with a filter 10 through a connecting mechanism. The right end of the electric heating tank 4 is connected with one side of the top of the drying tank 1 through an air supply pipe 5, and the bottom end of the liquid storage tank 2 is connected with the top of the drying tank 1 through a liquid infusion pipe 3. The top of the drying tank 1 is provided with an atomizing mechanism, and the lower right side of the drying tank 1 is provided with a discharging mechanism, which transports the stock liquid in the liquid storage tank 2 to the atomizing mechanism, and the atomizing mechanism sprays the stock liquid into the interior of the drying tank 1 from top to bottom, and then the blower 8 transports the air to the interior of the electric heating tank 4, and the electric heating tank 4 can convert electrical energy into thermal energy to automatically heat the air, and transport the hot air to the top of the drying tank 1 through the air supply pipe 5, and the hot air dries the stock liquid into powder, and finally the powder is automatically transported to the outside through the discharging mechanism.

[0020] The connecting mechanism includes a fixed disk 9, a block 11, a telescopic rod 12, a clamping block 13 and a spring 14. The input end of the filter 10 is connected to the fixed disk 9. A plurality of blocks 11 are distributed in an annular manner on the outer side of the fixed disk 9. A plurality of groups of telescopic rods 12 are distributed in an annular manner on the inner side of the fixed disk 9. One end of a group of telescopic rods 12 is connected to a clamping block 13. A telescopic rod 12 is provided on the outer side of the telescopic rod 12. An extension tube is provided at one end of the filter 10. A slot matching the block 11 is provided at one end of the filter 10. The shape of the clamping block 13 is set as an arc structure, so that the filter 10 with an extension tube is connected to the filter 10. One end of the tube is inserted into the interior of the fixed disk 9, and the outer wall of the extension tube is first squeezed inward by the clamp block 13 to squeeze the telescopic rod 12 and the spring 14 until the extension tube is completely inserted into the interior of the fixed disk 9. Then the spring 14 generates elastic force to drive the clamp block 13 to reset through the telescopic rod 12, so as to clamp the extension tube through the clamp block 13. At this time, the filter 10 and the fixed disk 9 are connected to each other. When air is drawn at the input end of the blower 8, the air will pass through the inside of the filter 10 to filter. When disassembly is required, the filter 10 is directly pulled upward to pull the extension tube out of the interior of the fixed disk 9.

[0021] The discharging mechanism includes a rotary discharger 6, a feeding pipe 7, a bag dust collector 17 and an exhaust fan 18. The right side of the bottom of the drying tank 1 is connected to the rotary discharger 6 through the feeding pipe 7. The top of the rotary discharger 6 is connected to the bag dust collector 17. The exhaust fan 18 is installed above the bag dust collector 17. The input end of the exhaust fan 18 is connected to the top of the bag dust collector 17. The dust airflow is transported into the interior of the rotary discharger 6 through the feeding pipe 7. When the rotary discharger 6 contains When the dust airflow enters the air pipe, the airflow will change from linear motion to circular motion. Most of the rotating airflow flows downward along the wall of the device along the cone. The dust-containing gas generates centrifugal force during the rotation process, which throws the dust particles heavier than the gas to the device wall, and falls along the wall to the bottom discharge valve for discharge, so as to automatically discharge the powder. The gas is discharged into the bag-type dust collector 17, and some of the powder will flow upward with the gas. The bag-type dust collector 17 can intercept this part of the powder and discharge it out.

[0022] A No. 1 motor 19 is installed at the bottom end of the drying tank 1. The output end of the No. 1 motor 19 passes through the bottom end of the drying tank 1 and is connected to a rotating frame 20. Scrapers 21 are symmetrically connected to both sides of the rotating frame 20. The outer side of the scraper 21 is closely connected to the inner wall of the drying tank 1. The No. 1 motor 19 can drive the rotating frame 20 to rotate inside the drying tank 1, and the scraper 21 is closely connected to the inner wall of the drying tank 1, and the scraper 21 is connected to the rotating frame 20, so the scraper 21 can rotate to scrape the powder on the inner wall of the drying tank 1, so as to facilitate the automatic transportation of the powder to the inside of the rotary discharger 6.

[0023] A feed pipe 22 is connected to the left side of the top of the liquid storage tank 2, and a No. 2 motor 23 is installed on the top of the liquid storage tank 2. The output end of the No. 2 motor 23 passes through the top of the liquid storage tank 2 and is connected to a rotating shaft 24. The bottom end of the rotating shaft 24 is connected to a stirring blade 25. The raw liquid can be poured into the liquid storage tank 2 through the feed pipe 22. The No. 2 motor 23 can drive the stirring blade 25 to rotate inside the liquid storage tank 2 through the rotating shaft 24. The stirring blade 25 is used to automatically stir the raw liquid inside the liquid storage tank 2 to prevent the raw liquid from adhering to the inner wall of the liquid storage tank 2 and affecting its outward discharge.

[0024] The bag-type spray dryer is constructed by inserting one end of the filter 10 with the extension tube into the interior of the fixed disk 9. The outer wall of the extension tube is first squeezed inward by the clamping block 13 to squeeze the telescopic rod 12 and the spring 14 until the extension tube is completely inserted into the interior of the fixed disk 9. Then, the spring 14 generates elastic force to drive the clamping block 13 to reset through the telescopic rod 12, so as to clamp the extension tube through the clamping block 13. At this time, the filter 10 and the fixed disk 9 are connected to each other. When air is extracted at the input end of the blower 8, the air will pass through the interior of the filter 10 to filter. When disassembly is required, the filter 10 is directly pulled upward to pull the extension tube out of the interior of the fixed disk 9.
