The dryer 2 is arranged on the right side of the blower 1. A pipeline 3 is connected between the blower 1 and the dryer 2. An air outlet 4 is arranged on the left side at the top of the dryer 1. A pressure regulating valve 5 is arranged on the left side of the outer wall of the dryer 2. A backwashing tank 6 is arranged at the bottom of the dryer 2. The filter plate frame mechanism includes a support seat 7 arranged on the right side of the dryer 2. Support feet 8 are arranged around the bottom of the support seat 7. Fixed blocks 9 are arranged on the left and right sides at the top of the support seat 7. Fixed frames 10 are arranged on the top of the fixed blocks 9. Fixed cross plates 11 are fixedly installed at both the front and rear ends of the fixed frames 10. A number of filter plate frames 12 are arranged between the two fixed frames 10. Fixed handles 13 are slidably installed at both ends of the front and rear outer walls of the filter plate frames 12. A waste funnel 14 is arranged at the bottom of the filter plate frames 12 between the two fixed blocks 9.

[0028] In this embodiment, support rods 15 are arranged around the bottom of the dryer 2. The backwashing tank 6 is arranged between the four support rods 15. The backwashing tank 6 is also connected to the dryer 2 through a pipeline 3.

[0029] In this embodiment, limit sleeves 18 are arranged at both the front and rear ends of the two fixed cross plates 11. A U-shaped pipeline 16 is connected between the four limit sleeves 18.

[0030] It should be noted that the limit sleeves 18 facilitate the fixation of the U-shaped pipeline 16.

[0031] In this embodiment, the dryer 2 is also connected to the filter plate frame mechanism through a pipeline 3. The pipeline 3 connected to the dryer 2 is connected to the front end of the U-shaped pipeline 16. A valve is arranged at the connection between the U-shaped pipeline 16 and the pipeline 3.

[0032] It should be noted that the valve can control whether the drying gas can enter the U-shaped pipeline 16.

[0033] In this embodiment, connecting pipes 17 are arranged between the U-shaped pipeline 16 and the fixed cross plates 11. The connecting pipes 17 are connected to the inside of the fixed cross plates 11 through the fixed cross plates 11.

[0035] It should be noted that the opening facilitates the discharge of the moisture in the U-shaped pipeline 16 into the waste funnel 14 during backwashing.

[0036] Working principle: When in use, first, the air blower 1 extracts air and sends the air into the dryer 2. Then, the dryer 2 heats the air and sends it into the U-shaped pipe 16 through the pipeline 3. At the same time, the air is sent into the backflush tank 6. Then, the dry gas is sent into the filter plate frame 12 through the connecting pipe 17 on the U-shaped pipe 16. The waste residues and other substances generated during the drying process in the filter plate frame 12 fall into the waste funnel 14 at the bottom. When the internal pressure of the dryer 2 is insufficient, the backflush tank 6 releases compressed gas for backflushing. The moisture inside the dryer 2 is discharged from the air outlet 4, and the moisture inside the U-shaped pipe 16 is discharged from the bottom opening at the other end far from the pipeline 3 into the waste funnel 14.
