[0029] The first aspect of the present application is,Figure 1 , Figure 2 and Figure 4 As shown, drying towers typically use hot air convection for drying, or sometimes adsorbents to absorb moisture. However, potassium persulfate powder should not be placed in a high-temperature environment for extended periods, as it is prone to decomposition and may even transform into other materials at high temperatures. Therefore, this embodiment uses cold air for drying.
[0030] Specifically, a pre-filter 109 is fixedly connected inside the drying tower body 101, dividing the interior of the drying tower body 101 into a drying chamber 110 and a partition chamber 111. Additionally, an exhaust pipe 107 is fixedly connected to the drying tower body 101, communicating with the partition chamber 111. Furthermore, the drying tower body 101 is also equipped with an air inlet 112 communicating with the drying chamber 110, used to introduce dry, cold air into the drying chamber 110.
[0031] The drying tower body 101 is equipped with a base 102 at its bottom, and a feed pipe 104 is fixedly connected to the drying tower body 101 via the base 102. The feed pipe 104 is connected to the bottom of the drying chamber 110. In addition, a discharge port 105 is provided at the top of the drying tower body 101, and the discharge port 105 is connected to the top of the drying chamber 110.

[0036] A plurality of stirring fan blades 113 are arranged in drying cavity 110, and cooperate with the dry cold air blown in by a plurality of air inlets 112, so that the potassium bisulfate material powder in drying cavity 110 is stirred and scattered.In addition, the adhesion and caking of potassium bisulfate material powder can also be more easily dispersed, so that the drying effect is greatly improved.
[0037] In addition, a vibration motor 114 is arranged in the drying tower body 101, and the vibration motor 114 is connected with the prefilter 109.And the bottom of the drying tower body 101 is also provided with a base 102, and the bottom of the base 102 is provided with an opening communicated with the partition cavity 111, and the opening is detachably connected with the material collecting drawer 108.

[0039] The utility model discloses a drying tower body 101 is set up in front filter screen 109 to divide the drying tower body 101 into drying cavity 110 and partition cavity 111, wherein drying cavity 110 is used for drying potassium bisulfate material powder.
[0040] In addition, the front filter screen 109 is connected with a vibration motor 114, which can shake the potassium bisulfate material powder attached to the front filter screen 109.
