[0002] During papermaking, paper mills generate a large amount of wastewater containing sludge.

[0003] Existing papermaking sludge is separated into solid and liquid components through sedimentation. The sludge has a certain degree of viscosity and tends to accumulate at the discharge port during discharge, causing blockage. This affects both sludge collection and sedimentation. Furthermore, the sludge still contains a certain amount of water, and if a large amount of water is discharged, it will make subsequent treatment difficult. Utility Model Content

[0024] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Please refer to Figures 1 to 4 As shown, a pulp and paper sludge collection device of the present invention includes a sedimentation tank 64, a water collection tank 3, a discharge mechanism 5, a knocking mechanism 1, and a sludge collection tank 2. The discharge mechanism 5 is provided at the bottom of the sedimentation tank 64, and the water collection tank 3 is provided below the end of the discharge mechanism 5 near the sedimentation tank 64. The knocking mechanism 1 is connected to the discharge mechanism 5, and the sludge collection tank 2 is provided below the end of the discharge mechanism 5 away from the sedimentation tank 64.

[0026] The discharge mechanism 5 includes a conveying component 51 and a conveying pipe. The conveying component 51 is installed inside the conveying pipe. The conveying pipe is inclinedly installed at the lower part of the sedimentation tank 64. The conveying pipe includes a sludge inlet 52, a water filtration section 53, and a sludge outlet 54. The sludge inlet 52 is connected to the lower part of the sedimentation tank 64. The water filtration section 53 and the sludge outlet 54 are both installed outside the sedimentation tank 64. The water filtration section 53 is connected to the water collection tank 3. The sludge collection tank 2 is installed below the sludge outlet 54. The striking mechanism 1 is movably connected to the upper part of the sludge outlet 54.

[0027] The working principle of this utility model is as follows: In actual production and use, when it is necessary to collect sludge from pulp and paper wastewater, the wastewater can be put into the sedimentation tank 64 for sedimentation. After sedimentation over time, the sludge in the wastewater enters the sludge inlet 52 of the conveying pipe. Then, the conveying component 51 is operated, which carries the sludge that has settled to the sludge inlet 52 to the filtration section 53, so that the excess water in the sludge enters the collection tank 3 through the filtration section 53, thereby reducing the water content in the sludge. Then, the conveying component 51 continues to operate, which transports the sludge from the filtration section 53 to the sludge outlet 54 for discharge. In order to discharge better, the beating mechanism 1 can be operated, which continuously beats the outside of the sludge outlet 54, so that the sludge inside the sludge outlet 54 can be dispersed under the beating of the beating mechanism 1, so that the sludge falls better into the collection tank 2 below for collection.

[0028] Furthermore, the striking mechanism 1 includes a bracket 107, a connecting rod 101, a plurality of striking rollers 105, a first rotation drive 104, a rotating shaft 103, and a pressing head 102. The bracket 107 is fixedly connected to the outer surface of the sedimentation tank 64. A plurality of striking rollers 105 are arranged on one side of the bracket 107. Each striking roller 105 is rotatably connected to the bracket 107. One end of each striking roller 105 is provided with a striking part 106. Each striking part 106 is movably connected to the outside of the sludge discharge part 54. The other end of each striking roller 105 is connected to the connecting rod 101. The rotating shaft 103 is rotatably connected to the other side of the bracket 107. The pressing head 102 is provided on the bracket 107. The pressing head 102 is movably connected to the connecting rod 101. The first rotation drive 104 is drivenly connected to the rotating shaft 103.

[0029] As can be seen from the above description, in order to better discharge sludge into the sludge collection tank 2, the first rotating drive component 104 can be operated, so that the first rotating drive component 104 drives the pressing head 102 to rotate through the rotating shaft 103, so that the pressing head 102 drives one end of several striking rollers 105 to press down through the connecting rod 101, so that the striking rollers 105 rotate on the support 107 under the pressure of the pressing head 102. When the pressing head 102 releases the pressure on the connecting rod 101, the striking part 106 of the striking roller 105 strikes the sludge discharge part 54, so that the sludge in the sludge discharge part 54 can be loosened and can be discharged into the sludge collection tank 2 more smoothly.

[0030] Furthermore, the conveying assembly 51 includes a second rotation drive 509 and a spiral conveying rod 502. The spiral conveying rod 502 is rotatably connected to the inside of the conveying pipe, and the second rotation drive 509 is rotatably driven connected to the spiral conveying rod 502.

[0031] As can be seen from the above description, when it is necessary to transport the settled sludge, the second rotation drive 509 can be operated so that the second rotation drive 509 can gradually transport the sludge in the sludge inlet 52 to the filtration section 53 and the sludge outlet 54 through the screw conveyor 502.

[0032] Furthermore, the sludge inlet 52 of the conveying pipe includes a first pipe body 501, the upper part of the first pipe body 501 is provided with a sludge inlet, the lower part of the sedimentation tank 64 is provided with an opening, the opening is connected to the sludge inlet, and the higher end of the first pipe body 501 is connected to the water filtration section 53.

[0033] As can be seen from the above description, it is beneficial for the sludge in the sedimentation tank 64 to settle into the first pipe body 501 through the sludge inlet, and then the conveying component 51 is operated to transport the sludge in the first pipe body 501 to the water filtration section 53 for water filtration.

[0034] Furthermore, the filtration section 53 includes a second pipe 504, a sleeve 508, and a water inlet pipe 507. The lower end of the second pipe 504 is connected to the first pipe 501, and the higher end of the second pipe 504 is connected to the sludge outlet section 54. The second pipe 504 is provided with a plurality of drainage holes 503. The sleeve 508 is sleeved on the outside of the second pipe 504. A gap is provided between the sleeve 508 and the second pipe 504. A drain outlet is provided at the lower part of the sleeve 508. A water inlet is provided at the upper part of the water collection tank 3. The drain outlet is connected to the water inlet through the water inlet pipe 507.

[0035] As can be seen from the above description, the sludge containing moisture is transported to the second pipe body 504 through the conveying component 51 and then stays in the second pipe body 504. The moisture in the sludge enters the casing 508 through the water leakage hole 503, and then the water is discharged into the water collection tank 3 through the water inlet pipe 507 for collection. After the water is filtered, the conveying component 51 is run again to transport the sludge from the pipe body to the sludge outlet 54 for discharge.

[0036] Furthermore, the mud discharge section 54 includes a third pipe body 505 and a mud discharge hopper 506. The lower end of the third pipe body 505 is connected to the second pipe body 504, and the lower part of the higher end of the third pipe body 505 is provided with a mud discharge port. The mud discharge hopper 506 is provided on the mud discharge port. The mud collection pool 2 is provided below the mud discharge hopper 506. The striking part 106 is movably connected to the outside of the third pipe body 505.

[0037] As can be seen from the above description, when the conveying component 51 conveys the sludge through the second pipe 504 to the inside of the third pipe 505, the sludge reaches the sludge outlet and is discharged into the sludge collection tank 2 through the sludge discharge hopper 506. In order to better discharge the sludge, the knocking roller 105 continuously knocks on the outside of the third pipe 505, so that the relatively sticky sludge inside the third pipe 505 is loosened, and the sludge is discharged from the sludge outlet better.

[0038] Furthermore, it also includes a PLC controller, which is electrically connected to the discharge mechanism 5 and the striking mechanism 1 respectively.

[0039] As can be seen from the above description, it is beneficial to adjust the parameters of the pulp and paper sludge collection device through the PLC controller, and it makes it more convenient for operators to operate the pulp and paper sludge collection device. Example 1
