Then, when the water level is insufficient, the water inside the recovery tank 1 is pumped out through the output end of the filter tank 5 and transported to the inside of the backwater pit 14 through a hose. Then, when it is necessary to disassemble the first filter plate 18, the push block 8 is pushed to move in the opposite direction of the limit block 9 to drive the return spring 6 to contract and drive the limit block 9 to move. Then, the limit block 9 is moved to make the other end of it disengage from the inside of the groove opened on the outer wall of the fixed block 19.

Then, when it is necessary to disassemble the second filter plate 20, the fixing bolt on the filter tank 5 is screwed to make the other end of it disengage from the inside of the groove opened on the outer wall of the water inlet pipe 16. Then, the filter tank 5 can be pulled to remove the filter tank 5 and the second filter plate 20 from the water inlet pipe 16.

[0042] The waste heat contained in the water in the waste heat recovery device flows in a spiral shape along the spiral tube groove 21 opened inside the recovery tank 1 through the spiral tube 22. At the same time, the water inside the recovery tank 1 is preheated by the waste heat inside the water, which avoids the waste heat in the water from being effectively utilized, thereby reducing energy consumption and production costs, and improving the practicality of the equipment. By pushing the pushing block 8 to move in the opposite direction of the limit block 9, the reset spring 6 is contracted and the limit block 9 is moved at the same time. Then, the limit block 9 is moved to make its other end disengage from the inside of the groove opened on the outer wall of the fixed block 19, and then the sliding seat 1 can be pulled The sliding seat 12 and the first filter plate 18 are taken out from the filter tank 5, which is convenient for the staff to disassemble the first filter plate 18, effectively improving the efficiency of the maintenance and repair of the first filter plate 18, and reducing the workload of the staff.

[0043] Working principle: First, connect it with the water inlet pipe 16 through the external device, then the external device transports water to the inside of the recovery tank 1 through the water inlet pipe 16, and at the same time, the water enters the inside of the recovery tank 1 after being processed by the second filter plate 20 inside the reset spring 6, and then drives the liquid level meter 23 to move downward through the output end of the cylinder 10, while driving the probe 24 to move downward, and then the water level inside the backwater pit 14 is measured through the cooperation of the probe 24 and the liquid level meter 23, and then the measured structure is transmitted to the control panel 3, and displayed on the display screen of the control panel 3. When the water level is high, the water inside the backwater pit 14 is pumped out through the output end of the second water pump 11 and transported to the inside of the filter tank 5 through a hose, and then the water passes through the first filter plate 18 inside the filter tank 5 and is processed and enters the inside of the spiral tube 22 through a hose, and then the residual heat contained in the water is spirally transmitted through the spiral tube 22 along the recovery tank 5. The spiral tube groove 21 opened inside the pool 1 flows, and the water inside the recovery pool 1 is preheated by the residual heat inside the water. Then, when the water level is insufficient, the water inside the recovery pool 1 is extracted through the output end of the filter tank 5 and transported to the inside of the backwater pit 14 through a hose. Then, when it is necessary to disassemble the first filter plate 18, the pushing block 8 is pushed to move in the opposite direction of the limit block 9 to drive the return spring 6 to contract and drive the limit block 9 to move. Then, the limit block 9 is moved to make the other end of it disengage from the inside of the groove opened on the outer wall of the fixed block 19. Then, the sliding seat 12 can be pulled to remove the sliding seat 12 and the first filter plate 18 from the filter tank 5. Then, when it is necessary to disassemble the second filter plate 20, the fixing bolt on the filter tank 5 is screwed to make the other end of it disengage from the inside of the groove opened on the outer wall of the water inlet pipe 16. Then, the filter tank 5 can be pulled to remove the filter tank 5 and the second filter plate 20 from the water inlet pipe 16.
