Detailed Implementation

[0025] In view of the shortcomings of the prior art, the inventor of this case, through long-term research and extensive practice, has come up with the technical solution of this utility model. The following will further explain the technical solution, its implementation process, and its principles.

[0026] like Figure 1 As shown, this utility model discloses a vibration-assisted slurry filter press, which includes a slurry pump 1, a coarse screen vibration mechanism 2, a slurry storage tank 3, a fine screen vibration mechanism 4, a slurry pump 5, a water storage tank 8, a mud-water pump 10, and a filter press mechanism 9. The slurry pump 1 is used to extract slurry, and a pipeline is connected to the slurry pump 1. The slurry pump 1 extracts slurry onto the coarse screen vibration mechanism 2.

[0027] The coarse screen vibration mechanism 2 is at least used to separate large particles of slag, specifically, such as... Figure 2 As shown, the coarse screening vibration mechanism 2 includes a coarse screen 11, and at least one first vibration motor 12 is provided on one side of the coarse screen 11. In this embodiment, two first vibration motors 12 are provided below the coarse screen 11. Driven by the first vibration motors 12, the coarse screen 11 vibrates to separate large particles of slag and slurry. Preferably, the coarse screen 11 is inclined toward the first slag discharge assembly 6 so that the large particles of slag screened by the coarse screen move toward the first slag discharge assembly 6. A first slag discharge assembly 6 for discharging large particles of slag is provided on one side of the coarse screening vibration mechanism 2; specifically, the first slag discharge assembly 6 includes a first conveyor belt and a first power assembly for driving the first conveyor belt. Driven by the first power assembly, the first conveyor belt discharges the large particles of slag.

[0028] The slurry storage tank 3 is located below the coarse screen vibration mechanism 2, and the slurry filtered by the coarse screen vibration mechanism 2 flows into the slurry storage tank 3. The slurry storage tank 3 is used at least temporarily to store the slurry after coarse screening.

[0029] The vibrating screening mechanism 4 is at least used to separate particulate slag, specifically, as follows: Figure 3 As shown, the fine screening vibration mechanism 4 includes a fine screen 41, and at least one second vibration motor 42 is provided on one side of the fine screen 41. In this embodiment, two second vibration motors 42 are provided. The fine screen 41 vibrates under the drive of the second vibration motors 42 to separate the slag and slurry. The mesh size of the fine screen 41 is smaller than that of the coarse screen 11.

[0030] A second slag discharge assembly 7 is provided on one side of the fine screening vibration mechanism 4 for discharging the slag after fine screening. The second slag discharge assembly 7 includes a second conveyor belt and a power mechanism for driving the second conveyor belt. The power mechanism can be a motor, sprocket and chain, or a motor, synchronous pulley and synchronous belt. In this embodiment, the power mechanism includes a motor, synchronous pulley and synchronous belt.

[0031] The slurry pump 5 is equipped with a fine screening vibration mechanism 4 on one side. The slurry pump 5 pumps the slurry in the slurry storage tank 3 into the fine screening vibration mechanism 4 through a pipeline.

[0032] The water storage tank 8 is located below the fine screening vibration mechanism 4, and the water storage tank 8 is used at least to store the mud and water after fine screening; the mud and water pump 10 is located on one side of the water storage tank 8, and the mud and water pump 10 is used at least to pump the mud and water in the water storage tank 8 into the filter press mechanism 9.

[0033] The filter press 9 is at least used to filter the mud into mud cakes, specifically, as follows: Figure 4 As shown, the filter press mechanism 9 includes a fixed frame 91, on which a plurality of filter press plates 92 are disposed. The filter press plates 92 are slidably connected to the fixed frame 91, and each of the filter press plates 92 is provided with a filter cloth. A fixed seat 93 is provided at one end of the fixed frame 91, and a pushing mechanism 94 is provided at the other end of the fixed frame 91. The pushing mechanism 94 is used to drive the filter press plates 92 to move towards or away from the fixed plate. When sludge needs to be filtered, the pushing mechanism 94 moves the filter press plates 92 towards the fixed seat 93 to press two adjacent filter press plates 92 together. When filtration is completed and the filter cake needs to be unloaded, the pushing mechanism 94 drives the filter press plates 92 to move away from the fixed seat 93 so that there is a gap between two adjacent filter press plates 92, allowing the filter cake to fall from the gap between the two adjacent filter press plates 92.

[0034] This application includes a coarse screening vibration mechanism 2 and a fine screening vibration mechanism 4, which can screen out large and medium-sized particles of slag, resulting in fewer impurities in the slurry, better dewatering effect during filter pressing, improved filter pressing dewatering rate, and reduced filter cake moisture content.

[0035] In some implementation examples, a shaking mechanism is provided on the fixed frame 91 to assist the filter cake in falling off. This shaking mechanism is slidably connected to the fixed frame 91 and is used at least to shake the filter press plate 92 to assist the filter cake in falling off. Specifically, such as... Figure 5 As shown, the shaking mechanism includes a plate-pulling trolley 98, which moves towards or away from the fixed base 93 under the drive of a power mechanism. The plate-pulling trolley is equipped with grippers 96, gripper cylinders, and a drive mechanism 97. The grippers are used to clamp the filter plate, and the gripper cylinders are used to drive the grippers to open or close. When the filter plate 92 needs to be moved, the gripper cylinders drive the grippers to open and close, so that the grippers clamp a corner of the filter plate 92. The drive mechanism is used to drive the filter plate to shake, so that the sludge cake on the filter plate 92 is shaken off. The driving mechanism can be a motor and a lead screw, or it can be a cylinder. In this embodiment, the driving mechanism includes a cylinder. The driving end of the cylinder is fixed on the pull plate trolley and is located between two grippers. When the grippers move the filter press plate 92 to create a gap between two adjacent filter press plates 92, the cylinder drives the filter press plate 92 to move up and down (at this time, the grippers do not grip the filter plate), causing the filter press plate 92 to shake, thereby shaking off the filter cake on the filter press plate 92. This application can automatically drive the filter press plate 92 to move, replacing manual labor and saving labor. At the same time, the shaking mechanism in this application can drive the filter press plate 92 to shake, assisting the filter cake to detach from the filter press plate 92, improving the efficiency of filter cake unloading.

[0036] In some implementation examples, to prevent slurry from settling and forming silt at the bottom of the slurry storage tank 3, a backflushing pipeline is installed on the slurry pump 5. A backflushing valve is connected to the backflushing pipeline, and the end of the backflushing pipeline furthest from the slurry pump 5 is connected to the bottom of the slurry storage tank 3. The backflushing valve is periodically opened, and the slurry pump 5 delivers slurry to the bottom of the slurry storage tank 3, flushing up the sludge and preventing it from settling at the bottom of the slurry storage tank 3.

[0037] It should be understood that the above embodiments are merely illustrative of the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
