Description

Technical Field

[0001] This utility model relates to the field of sludge treatment technology, specifically to a separation device for sludge washing. Background Technology

[0002] In some production buildings, a mixture of wastewater and sludge is generated. To avoid the direct discharge of sludge and its impact on the environment, it is necessary to carry out operations such as concentration, conditioning, dewatering, stabilization, drying or incineration of the sludge in order to achieve the treatment effects of sludge reduction, stabilization and harmlessness.

[0003] When cleaning and separating sludge, it is generally necessary to first perform preliminary filtration by sedimentation, and then squeeze the sludge for filtration. However, when using the squeeze filtration method, the sludge will block the filter holes during the squeezing process, thus hindering the separation of water. The pressure plate and filter screen need to be cleaned frequently, which reduces the separation efficiency and makes it inconvenient to use.

[0004] Therefore, a separation device for sludge washing is proposed. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0025] like Figure 1-5As shown, a sludge washing separation device includes a separation box 1 and a sealing cover 2. A support plate 901 is slidably mounted inside the separation box 1. A squeezing cylinder 3 is mounted on the sealing cover 2. A telescopic rod 10 is mounted at each of the four corners of the bottom of the sealing cover 2. A spring 1001 is sleeved on each telescopic rod 10. A squeezing frame 6 is connected to the telescopic end of the telescopic rod 10. A water-permeable hole 601 is opened at the bottom of the squeezing frame 6, penetrating its entire length. A pressure sensor 7 is mounted at the top of the squeezing frame 6. The sealing cover 2 is equipped with an air-blowing component 4 for backflushing and cleaning the water-permeable hole 601 and a water-collecting component 5 for collecting water. The air-blowing component 4 includes an air pump 401, a first connecting pipe 402, an air-blowing plate 403, and a high-pressure nozzle 404. The water-collecting component 5 includes a water pump 501, a water collection tank 502, a second connecting pipe 503, a water-drawing plate 504, and a water-drawing pipe 505. The air plate 403 and the water suction plate 504 are interconnected. The squeezing frame 6 is equipped with a driving component 8 that drives the air blowing plate 403 and the water suction plate 504 to move. The driving component 8 includes a slide rail 801, a motor 802, a lead screw 803, and a slider 804. Specifically, the sealing cover 2 can be fixed to the top of the separation box 1 by means of snap-fit, locking, or screw fixing. The fixing direction is not limited here. The pressure sensor 7 corresponds to the position of the squeezing cylinder 3. Therefore, when the sludge is squeezed, the squeezing force of the squeezing cylinder 3 acts on the pressure sensor 7, so the squeezing pressure value can be detected. When the squeezing pressure value reaches the set value, the squeezing cylinder 3 stops extending to avoid overload deformation of the squeezing frame 6 and ensure the squeezing force. The bottom of the squeezing frame 6 can be provided with reinforcing ribs to ensure that the bottom will not deform due to the squeezing force.

[0026] like Figure 1-3 As shown, the separation box 1 is equipped with a transparent viewing window 101. The bottom of the interior of the separation box 1 is equipped with an electric telescopic rod 9 and a limiting plate 902. The bearing plate 901 is connected to the telescopic end of the electric telescopic rod 9. Specifically, the limiting plate 902 can support the bearing plate 901, preventing the force from being directly applied to the electric telescopic rod 9 when the sludge is squeezed, thus preventing damage to it. To improve the sealing performance of the bearing plate 901, a sealing strip can be provided on its side, or a sealing plate flush with the height of the limiting plate 902 can be provided below the bearing plate 901 to prevent water from flowing down through the gaps in the bearing plate 901 when the sludge is squeezed. After the sludge is squeezed, the extension of the electric telescopic rod 9 can also push the sludge out of the interior of the separation box 1.

[0027] like Figure 2As shown, the air pump 401 and the air blowing plate 403 are connected by the first connecting pipe 402, and the high-pressure nozzles 404 are evenly arranged at the bottom of the air blowing plate 403. Specifically, after the sludge is squeezed for a period of time, the squeezing cylinder 3 contracts and drives the squeezing frame 6 to rise. At this time, the air pump 401 works to draw outside air into the air blowing plate 403 and spray it onto the squeezing frame 6 from the high-pressure nozzles 404. Therefore, it can play a backflushing role on the squeezing frame 6, blowing down the impurities blocking the permeable holes 601 to prevent them from clogging.

[0028] like Figure 3 As shown, the water pump 501 and the water pumping plate 504 are connected by a second connecting pipe 503. The water pumping pipe 505 is evenly arranged at the bottom end of the water pumping plate 504. The output end of the water pump 501 extends into the interior of the water collection tank 502. Specifically, when the sludge is squeezed, the water pump 501 can extract the squeezed and filtered water through the water pumping pipe 505 and finally collect it inside the water collection tank 502.

[0029] like Figure 2-3 As shown, both the first connecting pipe 402 and the second connecting pipe 503 are telescopic. The air blowing plate 403 and the water pumping plate 504 have the same length, and their lengths are adapted to the internal length of the separation box 1.

[0030] like Figure 5 As shown, the slide rail 801 is located at the top inside of the extrusion frame 6, the motor 802 is located on one side inside the slide rail 801, and the slider 804 is slidably located inside the slide rail 801. The slider 804 is threaded onto the lead screw 803, which is connected to the main shaft end of the motor 802. The air blowing plate 403 is connected to the slider 804. Specifically, the operation of the motor 802 can drive the lead screw 803 to rotate, thus driving the slider 804 to slide inside the slide rail 801, thereby driving the air blowing plate 403 and the water suction plate 504 to slide inside the extrusion frame 6. To avoid collisions between the air blowing plate 403 and the water suction plate 504 and the inside of the extrusion frame 6, causing motion interference, an encoder can be installed at the output end of the motor 802 to strictly control the travel path of the water suction plate 504 and the extrusion frame 6, ensuring that the extrusion frame 6 can be uniformly backflushed and blown, while also accelerating the suction of water.

[0031] In summary: The sludge and impurities after preliminary filtration and separation are poured into the interior of the separation box 1. Then, the squeezing cylinder 3 on the sealing cover 2 drives the squeezing frame 6 to press down, applying pressure to the sludge on the support plate 901 inside the separation box 1. This causes water to be filtered out through the water permeable holes 601 and pumped into the water collection tank 502 by the water pump 504 and the water suction plate 501. The pressure sensor 7 monitors the squeezing pressure in real time and stops when the set value is reached. Subsequently, the squeezing cylinder 3 retracts, and the squeezing frame 6 rises under the action of the spring 1001. Then, the air pump 401 and the high-pressure nozzle 404 back-blown water through the water permeable holes 601 to prevent clogging. The motor 802 of the drive component 8 drives the lead screw 803 to move the air blowing plate 403 and the water suction plate 504 laterally to ensure uniform cleaning and drainage. Finally, the electric telescopic rod 9 lifts the support plate 901 to complete the unloading.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
