The connection mechanism includes a card tube 8, a card rod 9, a locking frame 10, a moving groove 11, a compensation spring 12, a card groove 13 and a locking spring 14. The card rod 9 can be movably extended into the interior of the card tube 8, and the locking frame 10 can be laterally movably extended into the side wall of the card tube 8. The card groove 13 is arranged on the side of the card rod 9, and the moving groove 11 is arranged on the side wall of the card tube 8. The card rod 9 is arranged at both ends, and multiple groups of compensation springs 12 are installed between the two parts of the card rod 9, and the locking spring 14 is installed between the locking frame 10 and the outer wall of the card tube 8.

[0028] In this embodiment, the driving motor 2 is started, and the turntable 4 is driven to rotate through the rotating shaft 3. The multiple groups of separation leaves 5 on the turntable 4 separate the solid particles from the liquid in the incoming sewage. The solid particles are thrown to the outside of the filter chamber 6 by the separation leaves 5, and the liquid flows into the filter chamber 6 through the filter screen 7. The filter screen 7 further filters the liquid so that the clean liquid flows out of the filter chamber 6, and the solid particles are left on the filter screen 7, which is convenient for the rapid installation and disassembly of the filter screen 7. When it is necessary to fix or adjust the position of the filter screen 7, the card slot 13 of the clamping rod 9 cooperates with the moving slot 11 of the locking frame 10, and the locking spring 14 makes the locking frame 10 tightly fixed on the side wall of the clamping tube 8. The compensation spring 12 is installed between the two parts of the clamping rod 9 to adapt to different installation positions and compensate for possible gaps.

The lock head 19 is acted upon by the movable spring 20 to maintain a relative position with the spiral sleeve 15. When the spiral sleeve 15 rotates to an appropriate position, the lock head 19 enters the deep groove hole 17 and cooperates with the clamping groove 13 of the clamping rod 9, thereby fixing the position of the locking frame 10, and the sealing tube 21 prevents the locking frame 10 from moving outward, thereby ensuring the stability of the clamping.

[0031] See also Figure 1-6As a supplementary implementation of a solid-liquid separation device for sewage treatment for the rotating separation mechanism, the quick clamping mechanism and the clamping auxiliary mechanism: a mounting plate 22 is connected to the side of the filter chamber 6, a lateral plate 23 is connected to the side of the filter screen 7, and the lateral plate 23 is connected to the mounting plate 22 through a quick clamping mechanism, a connecting plate 24 is provided on the bottom side of the clamping tube 8, and the connecting plate 24 is fixedly installed on the top end surface of the lateral plate 23, one end of the clamping rod 9 is matched and arranged on the mounting plate 22, one end of the clamping rod 9 extends into the lateral plate 23, and further extends into the clamping tube 8, and the two end sides of the locking frame 10 An unlocking rod 25 is provided, and a directional push tube 32 is directional and movably arranged on the side of the clamping tube 8, and the directional push tube 32 can directional push the unlocking rod 25 to move the unlocking rod 25 away from the clamping slot 13. A box cover 26 is provided at the front opening end of the separation box 1, and a sealing cover 27 is provided at the front opening end of the filter chamber 6. A material adding pipe 28 is provided on the sealing cover 27, and the material adding pipe 28 is set through.

A mounting frame 31 is provided on the top end surface of the bottom plate 30, and the drive motor 2 is arranged on the top end surface of the mounting frame 31.

[0032] Specifically, sewage enters the separation box 1 through the box cover 26 and flows to the rotating separation mechanism. The rotating separation mechanism starts to work, and the separation leaves 5 and the filter screen 7 work together to separate the solid particles from the liquid in the sewage. The quick clamping mechanism and the clamping auxiliary mechanism ensure the correct position and stability of the filter screen 7 for effective solid-liquid separation. The clean liquid filtered by the filter screen 7 flows out of the filter chamber 6, and the solid particles are left on the filter screen 7. Periodically or as needed, the operator can unlock the quick clamping mechanism and take out the filter screen 7 for cleaning or replacement. If necessary, the treatment material or chemical agent can be added to the separation box 1 through the material addition pipe 28. The support plate 29 and the bottom plate 30 provide a stable foundation for the entire device. The drive motor 2 is installed on the bottom plate 30 through the mounting frame 31 to provide the power required for the rotating separation mechanism.

[0033] In summary, when the device is in operation: when the rotating separation mechanism needs to be operated, the drive motor 2 is started, and the turntable 4 is driven to rotate through the rotating shaft 3. The multiple groups of separation leaves 5 on the turntable 4 separate the solid particles from the liquid in the incoming sewage. The solid particles are thrown to the outside of the filter chamber 6 by the separation leaves 5, and the liquid flows into the filter chamber 6 through the filter screen 7. The filter screen 7 further filters the liquid, so that the clean liquid flows out of the filter chamber 6, and the solid particles are retained on the filter screen 7.

[0034] When the quick clamping mechanism is required to be operated, it is convenient to quickly install and disassemble the filter 7. When the position of the filter 7 needs to be fixed or adjusted, the clamping groove 13 of the clamping rod 9 cooperates with the moving groove 11 of the locking frame 10, and the locking spring 14 makes the locking frame 10 tightly fixed on the side wall of the clamping tube 8. The compensation spring 12 is installed between the two parts of the clamping rod 9 to adapt to different installation positions and compensate for possible gaps.

[0035] When the operation of the auxiliary mechanism is required, when fixing or adjusting the position of the filter 7, the spiral sleeve 15 starts to rotate, pushing the locking frame 10 to move in the moving groove 11, and cooperating with the compensation spring 12, the clamping rod 9 is stably installed inside the clamping tube 8, and the movable rod 18 moves with the rotation of the spiral sleeve 15. The lock head 19 is acted upon by the movable spring 20 to maintain the relative position with the spiral sleeve 15. When the spiral sleeve 15 rotates to the appropriate position, the lock head 19 enters the deep groove hole 17 and cooperates with the clamping groove 13 of the clamping rod 9, thereby fixing the position of the locking frame 10, and the sealing tube 21 prevents the locking frame 10 from moving outward, thereby ensuring the stability of the clamping.

[0036] The sewage enters the separation box 1 through the box cover 26 and flows to the rotating separation mechanism. The rotating separation mechanism starts to work, and the separation leaves 5 and the filter screen 7 work together to separate the solid particles from the liquid in the sewage. The quick clamping mechanism and the clamping auxiliary mechanism ensure the correct position and stability of the filter screen 7 for effective solid-liquid separation. The clean liquid filtered by the filter screen 7 flows out of the filter chamber 6, and the solid particles are left on the filter screen 7. Periodically or as needed, the operator can unlock the quick clamping mechanism and take out the filter screen 7 for cleaning or replacement. If necessary, the treatment material or chemical agent can be added to the separation box 1 through the material addition pipe 28. The support plate 29 and the bottom plate 30 provide a stable foundation for the entire device. The drive motor 2 is installed on the bottom plate 30 through the mounting frame 31 to provide the power required for the rotating separation mechanism.

In the above, all fixed connections are preferably welded.
