[0022] Embodiment 1:

[0023] As Figures 1-5 shown, a sodium sulfate anhydrous crystallization dryer of the present invention includes a dehumidification mechanism 1 and a feeding assembly 2. The dehumidification mechanism 1 includes a base 101. A dryer body 102 is provided at the top of the base 101. A fixed rod 103 is fixedly connected to the rear side of the top of the base 101. The feeding assembly 2 includes a feeding bin 201. The feeding bin 201 is located at the top of the dryer body 102. The rear end of the feeding bin 201 is fixedly connected to the front end of the top of the fixed rod 103. A top cover 202 is provided at the top of the feeding bin 201. A servo motor 203 is provided at the right end of the feeding bin 201. A sieve plate 104 is provided at the bottom of the feeding bin 201 at the input end of the top of the dryer body 102. A rolling roller 212 is provided at the top of the sieve plate 104.

[0024] As Figures 1-5 shown, inclined plates 204 are fixedly connected to the bottoms of the inner walls at the left and right ends of the feeding bin 201. A sliding groove 205 is formed on the inner wall at the rear end of the feeding bin 201.

[0025] As Figures 1-5 shown, a threaded rod 206 is provided inside the sliding groove 205. The left end of the threaded rod 206 is rotatably connected to the sliding groove 205 through a bearing. The right end of the threaded rod 206 is fixedly connected to the left end output of the servo motor 203.

[0026] During implementation, through the operation of the servo motor 203, the threaded rod 206 is driven to rotate, causing the nut seat 207 to move within the sliding groove 205. At this time, the sliding bracket 208 is driven to move, thereby driving the telescopic rod 210 and the lifting frame 211 to move, so that the rolling roller 212 makes a reciprocating motion, which can roll and break up the anhydrous sodium sulfate agglomerated due to moisture in the feed bin 201, preventing the agglomerated anhydrous sodium sulfate from directly entering the dryer body 102, improving the processing efficiency of the dryer 102 body for drying anhydrous sodium sulfate, and the overall structure is simple and convenient to use.

[0027] Embodiment 2:

[0028] As Figures 1-5 shown, on the basis of Embodiment 1, the present utility model provides a technical solution for an anhydrous sodium sulfate crystallization dryer: a nut seat 207 is sleeved on the threaded rod 206 through a thread, a sliding bracket 208 is fixedly connected to the front end of the nut seat 207, and a telescopic rod 209 is fixedly connected to the bottom end of the sliding bracket 208.

[0029] As Figures 1-5 shown, a lifting frame 211 is fixedly connected to the bottom end of the telescopic rod 209, a spring 210 is sleeved on the telescopic rod 209, and the front end of the lifting frame 211 is rotatably connected to the rear end of the rolling roller 212 through a rotating shaft.

[0030] As Figures 1-5 shown, a connecting frame 216 is rotatably connected to the front end of the rolling roller 212 through a rotating shaft, and a sliding rod 215 is fixedly connected to the top end of the connecting frame 216.

[0031] As Figures 1-5 shown, a limiting groove 213 is provided on the inner wall of the front end of the feed bin 201, a limiting plate 214 is provided in the limiting groove 213, and the top of the sliding rod 215 is sleeved on the limiting plate 214.

[0032] During implementation, through the setting of the feeding assembly 2, when the rolling roller 212 is moving, through the cooperation of the telescopic rod 209 and the spring 210, a better downward pressure can be applied to the rolling roller 212. Through the mutual cooperation of the movement, rotation and downward pressure of the rolling roller 212, the agglomerated anhydrous sodium sulfate can be more evenly and stably rolled and broken up on the sieve plate 104 and fall into the dryer body 102. The overall structure is simple and stable, and has good practicability.

[0033] In this embodiment: the servo motor is 60M-R6430A5-E.

[0034] The advantages of this technical solution in practical applications include but are not limited to the following points:

[0035] 1. By the operation of the servo motor 203, the rolling roller 212 makes a reciprocating motion, which can roll and disperse the anhydrous sodium sulfate agglomerated with moisture in the feed bin 201, avoiding the direct entry of the agglomerated anhydrous sodium sulfate into the dryer body 102, improving the processing efficiency of the dryer body 102 for drying anhydrous sodium sulfate, and the overall structure is simple and convenient to use.

[0036] 2. Through the cooperation of the telescopic rod 209 and the spring 210, a better downward pressure can be applied to the rolling roller 212. Through the mutual cooperation of the movement and rotation of the rolling roller 212 and the downward pressure, the agglomerated anhydrous sodium sulfate can be more evenly and stably rolled and dispersed on the sieve plate 104 and fall into the dryer body 102. The overall structure is simple and stable, with good practicability.

[0037] In this technical solution, first, the top cover 202 is opened to add the material to be processed into the feed bin 201. Then, the servo motor 203 operates to drive the threaded rod 206 to rotate, causing the nut seat 207 to move in the sliding groove 205. The nut seat 207 drives the sliding bracket 208 to move, thereby driving the telescopic rod 209 and the lifting frame 211 to move. At this time, the rolling roller 212 is driven to move at the top of the sieve plate 104. Through the setting of the spring 210, the rolling roller 212 can roll and disperse agglomerated anhydrous sodium sulfate of different sizes. Through the cooperation of the inclined plate 204 and the sieve plate 104, the unrolled and broken agglomerated anhydrous sodium sulfate will always remain in contact with the rolling roller 212 at the top of the sieve plate 104, effectively avoiding the problems of uneven drying and low drying efficiency caused by the direct entry of the agglomerated anhydrous sodium sulfate into the dryer body 102.

[0038] The above are only exemplary embodiments of the present disclosure and should not be used to limit the scope of the present disclosure. That is, any equivalent changes and modifications made in accordance with the teachings of the present disclosure still fall within the scope of the present disclosure. After considering the specification and the practice of the present disclosure, those skilled in the art will easily think of other implementation schemes of the present disclosure.
