[0025] In the specific implementation process, as Figure 1 shown, the access control structure 3 includes a bottom door 31 and a lock catch 32. One end of the bottom door 31 is rotatably connected to the bottom surface of the filter barrel 1, and the lock catch 32 is installed on the side wall of the bottom surface of the filter barrel 1 to facilitate the removal of the extruded waste residue cake.

[0026] In the specific implementation process, as Figure 1 、 Figure 2 and Figure 5 shown, the water discharge structure 5 includes a water outlet pipe 51, a water distribution tank 52, a sewage pipe 53, a water purification pipe 54 and a ball valve 55. The top end of the water outlet pipe 51 is communicated with the inside of the filter barrel 1. The water distribution tank 52 is installed on the side wall of the filter barrel 1, and the bottom end of the water outlet pipe 51 is inside the water distribution tank 52. The sewage pipe 53 and the water purification pipe 54 are symmetrically communicated with the bottom end of the water outlet pipe 51. The ball valve 55 is rotatably connected to the bottom end of the water outlet pipe 51. The water discharge structure 5 is provided to facilitate the distinction and control of the discharge of filtered clean water and sewage.

[0027] In the specific implementation process, as Figure 2 shown, the thickness of the filter cover 23 is equal to the vertical distance from the top surface of the extrusion plate 27 to the lowest end of the top pipe orifice of the water outlet pipe 51. When the bottom surface of the filter cover 23 abuts against the top surface of the extrusion plate 27, the top surface of the filter cover 23 is exactly at the same height as the pipe orifice of the water outlet pipe 51 on the inner wall of the filter barrel 1, facilitating the discharge of sewage from the water outlet pipe 51.

[0028] In the specific implementation process, such as Figure 1 and Figure 2 As shown, the pipeline structure 7 includes a measurement port 71, a water inlet pipe 72, and a valve 73. The measurement port 71 and the water inlet pipe 72 are provided on the side wall of the filter barrel 1. The three valves 73 are respectively installed on the side wall of the water outlet pipe 51, the side wall of the water inlet pipe 72, and the side wall of the diversion pipe 41. The measurement port 71 is provided to facilitate workers to measure the pH value of the waste liquid. The water inlet pipe 72 is provided to allow the wastewater to be treated to enter the filter barrel 1. The valve 73 is provided to close each pipeline and ensure the sealing performance inside the filter barrel 1, so that during the downward movement of the pressing plate 27, a negative pressure is generated in the upper part of the filter barrel 1, and the water in the lower part of the filter barrel 1 is sucked into the upper part of the filter barrel 1 through the cleaning pipe 61 to clean the inner wall of the filter barrel 1.

[0029] In the specific implementation process, such as Figure 2 and Figure 4 As shown, the convex block 25 abuts against and is slidably connected to the top inclined surface of the pushing plate 81. When the convex block 25 abuts against the top inclined surface of the pushing plate 81, it can push the pushing plate 81 to move, pull back the locking hook 85, so that the locking hook 85 no longer engages with the inner wall of the filter barrel 1; and the convex block 25 is engaged with the inside of the engaging hole 82, so that during the process of the convex block 25 abutting against the pushing plate 81, the pushing plate 81 is always engaged with the convex block 25 and will not move or the like.

[0030] In the specific implementation process, such as Figure 2 、 Figure 6 and Figure 7 As shown, the top end of the transmission rod 91 is of an arc-shaped structure. The top end of the transmission rod 91 abuts against the head of the locking hook 85 to stably abut against the locking hook 85 and prevent it from falling off, thus avoiding the situation that the locking hook 85 is not firmly locked; and the bottom end of the transmission rod 91 is fixed to the top surface of the closing plate 65, so that when the transmission rod 91 is bounced up by the fourth spring 92, the transmission rod 91 can drive the closing plate 65 to move upward, so that the water collection tank 62 is communicated with the inside of the filter barrel 1.

[0031] The working principle of the mixing plant sewage and waste residue cake recovery and treatment device provided by the present invention is as follows:

[0032] Connect the device to an external power supply, open the valve 73 on the water inlet pipe 72, and quantitative wastewater enters the lower space inside the filter barrel 1 (bounded by the extrusion plate 27) through the water inlet pipe 72. Close the valve 73 on the water inlet pipe 72, and add acid and coagulant through the measurement port 71 to form flocs in the suspended solids in the wastewater. At the same time, measure the pH value of the wastewater in the filter barrel 1 through the measurement port 71. Then add coagulant aid to the wastewater to make the flocs larger and conducive to precipitation, and let it stand for a period of time. Then, the external power supply supplies power to the water pump 42, and open the valve 73 on the diversion pipe 41. The water pump 42 pumps the supernatant after precipitation into the upper space in the filter barrel 1 through the diversion pipe 41. At the same time, open the valve 73 on the water outlet pipe 51, and rotate the ball valve 55 so that the water outlet pipe 51 communicates with the clean water pipe 54. The supernatant further filters out the organic pollutants and suspended solids in the supernatant through the first filter screen 24 in the filter hood 23. Since the plane of the extrusion plate 27 is lower than the height of the water outlet pipe 51 on the inner wall of the filter barrel 1, most of the filtered water flows out through the water outlet pipe 51, and a small part of the water remains on the top surface of the extrusion plate 27. After the supernatant above the diversion pipe 41 in the lower part of the filter barrel 1 is pumped dry, close the water pump 42 and the valve 73 on the diversion pipe 41. Since the bottom end of the diversion pipe 41 is higher than the bottom surface of the filter barrel 1 by a certain distance, there is still a part of the supernatant on the bottom surface of the filter barrel 1 in addition to the sediment. After waiting for the supernatant in the upper space of the filter barrel 1 to be filtered out, rotate the ball valve 55 so that the water outlet pipe 51 communicates with the sewage pipe 53. Then start the hydraulic cylinder 21, and the hydraulic cylinder 21 pushes the hydraulic rod 22 to extend. The hydraulic rod 22 drives the filter hood 23 and the first filter screen 24 to slide downward in the filter barrel 1. The filter hood 23 compresses the first spring 26 on its bottom surface. At the same time, the filter hood 23 and the first filter screen 24 squeeze the water on the top surface of the extrusion plate 27, and the water passes through the filter hood 23 and the first filter screen 24 in the reverse direction and reaches the top surface of the filter hood 23, which can perform backwashing on the filter hood 23 and the first filter screen 24. When the bottom surface of the filter hood 23 touches the top surface of the extrusion plate 27, stop extending the hydraulic rod 22. The top surface of the filter hood 23 is at the same height as the top pipe orifice of the water outlet pipe 51. The waste residue and water on the top surface of the filter hood 23 can be discharged into the sewage pipe 53 through the water outlet pipe 51, and then discharged outside the filter barrel 1. When the sewage pipe 53 no longer discharges sewage, close the valve 73 on the water outlet pipe 51. At the same time, continue to extend the hydraulic rod 22, and the filter hood 23 continues to squeeze the extrusion plate 27. The convex block 25 on the bottom surface of the filter hood 23 inserts into the insertion hole 29. At the same time, the convex block 25 touches the inclined surface of the push plate 81.The push plate 81 is caused to slide within the inner groove 28, the push plate 81 compresses the second spring 83, and the bump 25 finally engages with the engaging hole 82 along the inclined surface of the push plate 81. During this process, the locking hook 85 moves along with the push plate 81 and slowly moves out from the inner sidewall of the filter barrel 1, no longer engaging with the inner sidewall of the filter barrel 1 and no longer abutting against the top end of the transmission rod 91. The filter cover 23, the first filter net 24, and the extrusion plate 27 move downward together with the hydraulic rod 22. At the same time, the transmission rod 91 slides upward under the push of the fourth spring 92, driving the closing plate 65 to move upward, so that the water collecting tank 62 communicates with the interior of the filter barrel 1; since the valves 73 of each pipe in the upper part of the space inside the filter barrel 1 are all closed, the upper part of the space inside the filter barrel 1 is a closed space. The hydraulic rod 22 pushing the filter cover 23, the first filter net 24, and the extrusion plate 27 downward forms a piston effect, squeezing the wastewater at the bottom surface inside the filter barrel 1 into the water collecting tank 62. The wastewater is filtered by the second filter net 64, and the filtered clean water rises through the cleaning pipe 61 and enters the flushing ring 63, and the water is sprayed into the upper space inside the filter barrel 1 through the flushing ring 63 to clean the inner sidewall of the filter barrel 1. The water after cleaning is on the top surface of the filter cover 23. The hydraulic rod 22 drives the extrusion plate 27 to reach the bottom surface inside the filter barrel 1, compressing the precipitated waste residue into a cake. Rotate the lock 32 to open the bottom door 31 and take out the waste residue cake. Then open the valve 73 on the water outlet pipe 51 and rotate the ball valve 55 to connect the water outlet pipe 51 with the clean water pipe 54, and start the hydraulic cylinder 21 to retract the hydraulic rod 22. The hydraulic rod 22 drives the filter cover 23 and the first filter net 24 to rise. The filter cover 23 is separated from the extrusion plate 27, and the sewage on the top surface of the filter cover 23 falls on the top surface of the extrusion plate 27 through the first filter net 24. At the same time, the bump 25 is separated from the engaging hole 82, and the push plate 81 is reset under the push of the second spring 83, pushing out the locking hook 85. Due to the extrusion of the inner wall of the filter barrel 1, the locking hook 85 rotates upward, and its root compresses the third spring 84. At the same time, the first spring 26 elongates. When the first spring 26 no longer elongates, the extrusion plate 27 rises together with the filter cover 23 and the first filter net 24 until the locking hook 85 slides into the inner wall of the filter barrel 1. The extrusion plate 27 will rise a certain distance further. The head of the locking hook 85 is pushed by the inner wall of the filter barrel 1 and will rotate counterclockwise around the push plate 81, and its root drives the third spring 84 to elongate, and the head pushes the top end of the transmission rod 91 downward. The transmission rod 91 slides downward, driving the closing plate 65 to move downward to separate the water collecting tank 62 from the filter barrel 1.At this time, the hydraulic rod 22 resets; during the ascending process of the extrusion plate 27, the filtered water on the top surface of the extrusion plate 27 flows out through the water outlet pipe 51, and finally the bottom door 31 and the latch 32 are closed. Then, the next sewage treatment is carried out according to the above steps.

[0033] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
