After the centrifugal dehydration drum 24 rotates for a certain period of time, the control valve 210 is used to randomly discharge the sludge through the bottom end of the sludge discharge pipe 29.

[0027] Specifically, the guide groove 215 is located directly below the filter ring 212, and the bottom end of the collecting bucket 216 is connected to a drain pipe 218, which matches the position of the extrusion dehydration component 3. The rear wall of the guide groove 215 is connected to a drain pipe 217, which is "C" shaped, and the bottom end of the drain pipe 217 is connected to the rear wall of the extrusion dehydration component 3.

[0028] In this embodiment, when the sludge inside the centrifugal dehydration drum 24 is discharged through the bottom end of the sludge discharge pipe 29 and falls into the collecting bucket 216, it is discharged from the sewage discharge pipe 218, and the sewage inside the guide groove 215 is discharged into the water receiving frame 37 through the drainage pipe 217.

[0029] Specifically, the extrusion and dehydration assembly 3 includes a pressure-bearing cylinder 31, the right side of the top wall of the pressure-bearing cylinder 31 is fixedly connected to the bottom wall of the automatic pressure-bearing assembly 4, the top wall of the pressure-bearing cylinder 31 is fixedly connected to the top wall of the support frame 5, the top wall of the pressure-bearing cylinder 31 is connected to a receiving hopper 39, the receiving hopper 39 is located directly below the sewage pipe 218 and is connected, and the pressure-bearing cylinder 31 is in an inclined state with the left side higher and the right side lower.

[0030] In this embodiment, the pressure cylinder 31 is mainly used to contain the sludge that has been dehydrated, and receives the sludge discharged from the sewage pipe 218 through the receiving hopper 39.

[0031] Specifically, a water receiving frame 37 is fixedly installed on the bottom wall of the pressure-bearing cylinder 31 , a water outlet pipe 38 is connected to the right side wall of the water receiving frame 37 , and a rear wall of the water receiving frame 37 is connected to the front end of the drain pipe 217 .

[0032] In this embodiment, the water receiving frame 37 is mainly used to collect the discharged sewage and then perform subsequent purification treatment.

[0034] In this embodiment, the hydraulic rod 32 pushes the extrusion seat 33 to slide inside the pressure cylinder 31 to squeeze and dehydrate the sludge. The provision of the anti-stick coating 34 can reduce the degree of adhesion of the sludge.

[0035] Specifically, a mounting opening 35 is opened on the bottom wall of the pressure-bearing cylinder 31 , and a separation plate 36 is fixedly installed on the inner wall of the mounting opening 35 . The separation plate 36 is located on the upper part of the water receiving frame 37 .

[0036] In this embodiment, the sewage squeezed out of the pressure tube 31 is filtered and separated by the separation plate 36 and then falls into the water receiving frame 37 .

[0037] Specifically, the automatic pressure-bearing assembly 4 includes a U-shaped frame 42, which is fixedly connected to the right side of the outer wall of the pressure-bearing cylinder 31, and an electric push rod 41 is fixedly installed on the top wall of the U-shaped frame 42. The movable end of the electric push rod 41 slides through the U-shaped frame 42 and is fixedly installed with a lifting pressure-bearing seat 43.

[0038] In this embodiment, the lifting and lowering of the lifting pressure-bearing seat 43 is controlled by the extension and retraction of the movable end of the electric push rod 41. When the sludge is squeezed and dehydrated, the lifting pressure-bearing seat 43 is mainly used to prevent the sludge from being discharged from the pressure cylinder 31. When the extrusion and dehydration are completed, the lifting pressure-bearing seat 43 lifts the sludge and discharges it from the right side of the pressure cylinder 31.

[0039] Specifically, a positioning groove 44 is opened on the right side of the inner wall of the pressure-bearing cylinder 31 , and a through groove 45 is opened on the top wall of the pressure-bearing cylinder 31 at a position corresponding to the positioning groove 44 , and the through groove 45 is connected to the positioning groove 44 .

[0041] Specifically, the outer wall of the lifting pressure bearing seat 43 is slidably connected with the inner wall of the through groove 45 and the positioning groove 44 , and the sludge discharge frame 46 is fixedly installed on the right side wall of the pressure bearing cylinder 31 .

[0042] In this embodiment, after the sludge is squeezed and dehydrated, the lifting pressure seat 43 is raised, and the sludge is pushed by the hydraulic rod 32 to slide the squeezing seat 33 inside the pressure cylinder 31 through the sludge discharge frame 46 to be discharged outward for unified collection.

[0043] During operation, the drive motor 23, the hydraulic rod 32 and the electric push rod 41 are first electrically connected through an external power supply and a controller. When the sludge needs to be dehydrated, the sludge is injected into the centrifugal dehydration cylinder 24 through the feed hopper 6, and then the centrifugal dehydration cylinder 24 is driven by the drive motor 23 to start rotating. The centrifugal dehydration cylinder 24 drives the sludge inside it to start rotating at the same time, and the water contained in the sludge is thrown outward through the drainage hole 25 to the inside of the treatment cylinder 1. When the centrifugal dehydration cylinder 24 rotates, it will drive the fixed ring 26 and the reinforcing rib 27 to rotate. The reinforcing rib 27 rotates in the inner wall of the rotating bearing 28, and the water thrown out through the drainage hole 25 is discharged to the inside of the treatment cylinder 1. After passing through the inner wall of the treatment cylinder 1, it flows downward to the outer wall of the receiving bucket 211 and is collected. After passing through the filter ring 212, the sewage enters the guide groove 215 of the receiving cylinder 214. The sewage inside the guide groove 215 passes through the drain pipe 217 and is discharged into the water receiving frame 37 for storage. After the centrifugal dehydration cylinder 24 drives the sludge to rotate for a certain period of time, the control valve 210 is opened, so that the sludge inside the centrifugal dehydration cylinder 24 is discharged from the sludge discharge pipe 29 into the collection bucket 216 in the receiving cylinder 214 and is discharged from the sewage discharge pipe 218 into the receiving bucket 39. When the sludge passes through the receiving bucket 39 and enters the pressure cylinder 31, the sludge is discharged from the receiving bucket 39 to the receiving bucket 39. Afterwards, the hydraulic rod 32 is controlled by an external controller to start working, and the movable end of the hydraulic rod 32 pushes the squeezing seat 33 along the inner wall of the pressure-bearing cylinder 31 to start approaching the internal sludge. The squeezing seat 33 and the anti-stick coating 34 cooperate with each other to squeeze the sludge inside the pressure-bearing cylinder 31, so that the sewage inside the sludge is further discharged, and the sewage is discharged into the water receiving frame 37 through the separation plate 36 installed on the installation port 35 and collected uniformly. After the sludge is pushed to the right, it contacts and squeezes the lifting pressure-bearing seat 43. After squeezing the sludge, the movable end of the hydraulic rod 32 contracts and drives the squeezing seat 33 to slide to the left, and the movable end of the electric push rod 41 The contraction drives the lifting pressure-bearing seat 43 to slide upward along the inner walls of the positioning groove 44 and the through groove 45, thereby driving the positioning groove 44 to disengage from the pressure-bearing cylinder 31, so that the right side of the pressure-bearing cylinder 31 opens, and the movable end of the hydraulic rod 32 pushes the extrusion seat 33 to slide along the inner wall of the pressure-bearing cylinder 31, and the sludge inside the pressure-bearing cylinder 31 is discharged from the right side of the pressure-bearing cylinder 31, and is collected uniformly after passing through the sludge discharge rack 46. When the extrusion dehydration component 3 is working, it is a working window period of the centrifugal dehydration component 2. During this working period, the sludge continues to be centrifugally dehydrated by the centrifugal dehydration component 2 and the above-mentioned work process is repeated to continuously dehydrate the sludge.
