[0028] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example 1

[0030] See also Figure 1-7 As shown, the present application provides a spray drying tower for processing powder products, comprising a drying tower 1 and a spray head 2 arranged inside the drying tower 1;

[0031] The cleaning mechanism 3 is arranged inside the drying tower 1 , and is used to clean the inside of the drying tower 1 .

[0032] The cleaning mechanism 3 includes a scraper frame 32 driven to rotate by a driving mechanism 31. The scraper frame 32 is connected to a movable seat 34 through a reciprocating mechanism 33. A cleaning block 35 is fixedly connected to the movable seat 34. The top and bottom of the cleaning block 35 are both arranged to be inclined.

[0033] The driving mechanism 31 includes a motor 311 fixedly connected to the top of the drying tower 1, the motor 311 is electrically connected to an external power supply and controlled by an external control program, and an outer gear ring 312 is provided on the scraper frame 32. The output end of the motor 311 passes through the drying tower 1 and extends to the interior of the drying tower 1. The output end of the motor 311 is fixedly connected to a first gear 313, and the first gear 313 is engaged with the outer gear ring 312.

[0034] The reciprocating mechanism 33 includes a reciprocating screw 331 arranged on the scraper frame 32, and an inner gear ring 332 fixedly connected to the inside of the drying tower 1. The cleaning block 35 is arranged on the reciprocating screw 331. A second gear 333 is fixedly connected to the reciprocating screw 331, and the second gear 333 is engaged with the inner gear ring 332.

[0035] The scraper frame 32 includes a ring body 321, a connecting arm 322 fixedly connected to the outside of the ring body 321, and a first cleaning plate 323 fixedly connected to the connecting arm 322. The outer gear ring 312 is fixedly connected to the ring body 321, and the ring body 321 is located outside the nozzle 2. Two first cleaning plates 323 are provided, and the structures on the two first cleaning plates 323 are arranged symmetrically around the center. When the first cleaning plates 323 rotate, they rotate along the interior of the drying tower 1 with the side provided with the fixing seat 7 as the front and the side provided with the groove 4 as the rear.

[0036] The surface of the first cleaning plate 323 is provided with a groove 4, the reciprocating screw 331 is located in the groove 4, and the second gear 333 is located outside the first cleaning plate 323. Powder is attached to the inner wall of the drying tower 1 and the first cleaning plate 323 (but there is no powder attached to the upper part). When it is necessary to clean this powder, the motor 311 is turned on, and the motor 311 drives the first gear 313 to rotate. Then, through meshing transmission, the outer ring gear 312 is driven to rotate, which in turn drives the ring body 321 to rotate, thereby driving the first cleaning plate 323 to rotate through the connecting arm 322, thereby using the first cleaning plate 323 to clean the inner wall of the drying tower 1. When the first cleaning plate 323 rotates, the second gear 333 moves along the inner ring gear 332, thereby driving the second gear 333 to rotate, which in turn drives the reciprocating screw 331 to rotate, thereby driving the movable seat 34 to reciprocate up and down, thereby driving the cleaning block 35 to reciprocate up and down, and using the cleaning block 35 to clean the powder off the first cleaning plate 323.

[0037] Example 2

[0038] Based on Example 1, see Figure 4 、 Figure 6 and Figure 7 shown.

[0039] The surface of the first cleaning plate 323 is fixedly connected to a fixing seat 7, the bottom of the fixing seat 7 is rotatably connected to a connecting plate 8, a second cleaning plate 9 is fixedly connected to the connecting plate 8, and a reset mechanism 10 is provided between the second cleaning plate 9 and the first cleaning plate 323.

[0040] The bottom of the second cleaning plate 9 is arranged to be an inclined surface, and the length of the connecting plate 8 is smaller than the length of the second cleaning plate 9 .

[0041] The reset mechanism 10 includes a fixing hole 101 formed on the surface of the first cleaning plate 323. A spring 102 is fixedly connected to the fixing hole 101, and the spring 102 is fixedly connected to the second cleaning plate 9. When powder is attached to the inner wall of the drying tower 1 and the first cleaning plate 323 (but no powder is attached to the area near the top), when it is necessary to clean the powder, the motor 311 is turned on, and the motor 311 drives the first gear 313 to rotate, which in turn drives the outer gear ring 312 to rotate through meshing transmission, and then drives the ring body 321 to rotate, thereby driving the first cleaning plate 323 to rotate through the connecting arm 322, so that the first cleaning plate 323 can be used to clean the inner wall of the drying tower 1. When the first cleaning plate 323 rotates, the second gear 333 moves along the inner gear ring 332, thereby driving the second gear 333 to rotate, and then driving the reciprocating screw 331 to rotate, thereby driving the moving seat 34 to reciprocate up and down, thereby driving the cleaning block 35 to reciprocate up and down. When the cleaning block 35 moves downward, the cleaning block 35 is used to clean the powder on the first cleaning plate 323. When the cleaning block 35 moves upward, in the process of using the cleaning block 35 to clean the powder on 323, some powder will slide along the inclined surface above the cleaning block 35, and some powder will remain on the cleaning block 3 5, and when the cleaning block 35 continues to move upward under the action of the reciprocating screw 331 (in the upward movement area, there is no powder on the surface 323), the cleaning block 35 contacts the second cleaning plate 9. Thereafter, the second cleaning plate 9 is subjected to the thrust, and then the second cleaning plate 9 rotates on the fixed seat 7 through the connecting plate 8. The spring 102 is in a tensioned state. During the rotation of the second cleaning plate 9 and the upward movement of the cleaning block 35, the second cleaning plate 9 cleans the powder on the upper inclined surface of the cleaning block 35. The second cleaning plate 9 can be used to clean the powder remaining on the upper surface of the cleaning block 35. After the powder on the upper inclined surface of the cleaning block 35 is cleaned, the reciprocating screw 331 drives the movable seat 34 downward, and then drives the cleaning block 35 downward. The second cleaning plate 9 gradually loses the thrust of the cleaning block 35, and then under the elastic force of the spring 102, the second cleaning plate 9 gradually returns to its original position, thereby facilitating the next cleaning of the powder on the upper inclined surface of the cleaning block 35.

[0042] Example 3

[0043] Based on Example 1, see Figure 2 、 Figure 3 、 Figure 4 and Figure 5 shown.

[0044] A baffle 5 is fixedly connected to the surface of the first cleaning plate 323. A through slot 6 is formed through the top of the movable seat 34. One side of the through slot 6 is open, and the baffle 5 is slidably connected to the through slot 6. Powder adheres to the inner wall of the drying tower 1 and the first cleaning plate 323 (but there is no powder adhered to the area near the top). When this powder needs to be cleaned, the motor 311 is turned on, and the motor 311 drives the first gear 313 to rotate. The meshing transmission drives the outer gear ring 312 to rotate, which in turn drives the ring body 321 to rotate, thereby driving the first cleaning plate 323 to rotate via the connecting arm 322, thereby using the first cleaning plate 323 to clean the inner wall of the drying tower 1. When the first cleaning plate 323 rotates, the second gear 333 moves along the inner gear ring 332, thereby driving the second gear 333 to rotate, which in turn drives the reciprocating screw 331 to rotate, thereby driving the movable seat 34 to reciprocate up and down, and thus driving the cleaning block 35 to reciprocate up and down. When the cleaning block 35 moves downward, it is used to clean the powder on the first cleaning plate 323. During this process, the baffle 5 is provided to prevent the powder from entering the groove 4.

[0045] Example 4

[0046] In conjunction with Example 1, Example 2 and Example 3, see Figure 1-7 shown.

[0047] The inner wall of the drying tower 1 is cleaned by rotating the first cleaning plate 323. At the same time, the reciprocating screw 331 and the movable seat 34 are used to drive the cleaning block 35 to reciprocate to clean the first cleaning plate 323, thereby preventing the accumulation of powder on the first cleaning plate 323 and affecting its use.

[0048] The working principle of the present invention is as follows: powder is attached to the inner wall of the drying tower 1 and the first cleaning plate 323 (but no powder is attached to the part near the top). When the powder needs to be cleaned, the motor 311 is turned on, and the motor 311 drives the first gear 313 to rotate, and then through meshing transmission, the outer gear ring 312 is driven to rotate, and then the ring body 321 is driven to rotate, thereby driving the first cleaning plate 323 to rotate through the connecting arm 322, so that the first cleaning plate 323 is used to clean the inner wall of the drying tower 1. When the first cleaning plate 323 rotates, the second gear 333 moves along the inner gear ring 332, thereby driving the second gear 333 to rotate, and then driving the reciprocating screw 331 to rotate, thereby driving the movable seat 34 to reciprocate up and down, thereby driving the cleaning block 35 to reciprocate up and down. When the cleaning block 35 moves downward, the cleaning block 35 is used to clean the powder on the first cleaning plate 323. When the cleaning block 35 moves upward, in the process of cleaning the powder on the cleaning block 323, some powder will slide along the inclined surface above the cleaning block 35, and some powder will remain on the inclined surface above the cleaning block 35. When the cleaning block 35 continues to move upward under the action of the reciprocating screw 331 (the surface of 323 is not left in the upward movement area), The cleaning block 35 contacts the second cleaning plate 9, and then the second cleaning plate 9 is subjected to the thrust, and the second cleaning plate 9 rotates on the fixed seat 7 through the connecting plate 8, and the spring 102 is in a stretched state under the force. During the rotation of the second cleaning plate 9, the cleaning block 35 moves upward, so that the second cleaning plate 9 cleans the powder on the inclined surface above the cleaning block 35. The second cleaning plate 9 can be used to clean the powder remaining on the upper surface of the cleaning block 35, so that the first cleaning plate 323 is used to rotate to clean the inner wall of the drying tower 1. At the same time, the reciprocating screw 331 and the movable seat 34 are used to drive the cleaning block 35 to reciprocate, so as to clean the first cleaning plate 323, thereby avoiding the accumulation of powder on the first cleaning plate 323 and affecting its use. After cleaning the powder on the inclined surface above the cleaning block 35, the reciprocating screw 331 drives the movable seat 34 downward, thereby driving the cleaning block 35 downward. As a result, the second cleaning plate 9 gradually loses the thrust of the cleaning block 35. Then, under the elastic force of the spring 102, the second cleaning plate 9 gradually returns to its original position, making it easier to clean the powder on the inclined surface above the cleaning block 35 next time. In addition, when the movable seat 34 cleans the powder on the first cleaning plate 323, the baffle 5 is provided to prevent the powder from entering the groove 4.
