Figure 1-3 A refrigerated dryer for convenient filter element replacement includes a dryer body 1, a rectangular block 6 is arranged at the upper end of the dryer body 1, two sliding cavities 9 are symmetrically opened in the rectangular block 6, a slide plate 10 is slidably connected between the left and right inner walls of the two sliding cavities 9, and two limit rods 11 are fixedly connected to the lower ends of the two slide plates 10. A connecting mechanism for the refrigerated dryer is arranged on the dryer body 1.

[0021] The connection mechanism enables quick loading and unloading of the filter element, greatly shortening the replacement time and improving production efficiency.

[0022] Reference Figure 1-3 The connecting mechanism includes a knob 7 rotatably connected to the upper end of the rectangular block 6, and a threaded rod 12 is rotatably connected between the upper and lower inner walls of the two sliding cavities 9. The two threaded rods 12 are threadedly connected to the corresponding slide plates 10. The upper end of the threaded rod 12 on the left side extends to the upper end of the rectangular block 6 and is fixedly connected to the lower end of the knob 7. Synchronous transmission wheels are fixedly connected to the two threaded rods 12, and the two synchronous transmission wheels are connected through a synchronous transmission belt 13. The lower ends of multiple limit rods 11 extend into the dryer body 1, a filter element 2 is provided on one side of the dryer body 1, and a plurality of limit holes 4 matching the limit rods 11 are provided on the upper end of the filter element 2. A rubber sealing pad 5 is arranged around the dryer body 1, and a limit groove 8 is provided between the left and right inner walls of the dryer body 1.

[0023] By turning the knob 7, the threaded rod 12 on the left side rotates. When the threaded rod 12 on the left side rotates, the threaded rod 12 on the right side rotates through the transmission of the synchronous transmission belt 13, that is, the two threaded rods 12 rotate synchronously, and then the two slides 10 drive the corresponding limit rods 11 to move down into the limit hole 4 to complete the connection. When disassembly is required, the knob 7 is twisted in the opposite direction to make multiple limit rods 11 leave the corresponding limit holes 4.

[0024] Reference Figure 1-2 The left and right outer walls of the filter core 2 are both fixedly connected with limiting blocks 3 , and the two limiting blocks 3 are matched with the corresponding limiting grooves 8 .

By setting the rubber sealing pad 5, the sealing performance of the connection between the filter element 2 and the dryer body 1 can be increased;

[0026] Then, the knob 7 is turned to rotate the threaded rod 12 on the left side. When the threaded rod 12 on the left side rotates, the threaded rod 12 on the right side will rotate through the transmission of the synchronous transmission belt 13, that is, the two threaded rods 12 rotate synchronously, and then the two slides 10 drive the corresponding limit rods 11 to move down into the limit hole 4 to complete the connection. When disassembly is required, the knob 7 is twisted in the opposite direction to make the multiple limit rods 11 leave the corresponding limit holes 4. Through the connection mechanism, the filter element can be quickly loaded and unloaded, which greatly shortens the replacement time and improves the production efficiency.
