Description

Technical Field

[0001] This utility model relates to the field of sludge treatment technology, and in particular to a water treatment solid-liquid separation device. Background Technology

[0002] Water treatment refers to the removal or transformation of pollutants from raw water (sewage / wastewater / natural water bodies) through physical, chemical, or biological means to meet water quality standards for specific uses (such as drinking water, effluent, and industrial reclaimed water), while reducing harm to the environment and human health. During water treatment, pollutants in the water are separated or transformed to form sludge. Because sludge typically has a high water content, it is bulky and highly mobile, making it difficult to transport, store, and dispose of. Therefore, filter press equipment is needed for solid-liquid separation of the sludge. Currently, some filter press equipment suffers from large size and footprint issues in its design, and its operational stability needs improvement. Utility Model Content

[0020] like Figures 1-4 As shown in the embodiment of this application, a water treatment solid-liquid separation device is provided for water treatment of sludge and other materials generated from water treatment. It includes a frame 1, a pressing device 2, a filter assembly 3, and a plate pulling device.

[0021] The frame 1 includes a main beam 11 and legs supporting both ends of the main beam 11. The clamping device 2 includes a thrust plate 21, a clamping plate 22, and a hydraulic cylinder 23. The thrust plate 21 is located at one end of the main beam 11, the clamping plate 22 is slidably connected to the other end of the main beam 11, and the piston rod of the hydraulic cylinder 23 is connected to the clamping plate 22. The filter assembly 3 includes several filter plates 31 arranged and slidably connected to the main beam 11. The filter plates 31 are located between the thrust plate 21 and the clamping plate 22. Each filter plate 31 is covered with filter cloth on both sides, and the filter plates 31 are connected to each other. A filter chamber is formed between the filter components, and the filter cloth is used to filter solid particles. The solid particles are trapped in the filter chamber to form a filter cake. The plate pulling device is located on both sides of the main beam 11. It includes a motor, a sprocket transmission mechanism 4 and a plate pulling manipulator assembly 5. The plate pulling manipulator assembly 5 is mounted on the sprocket transmission mechanism 4 and slidably connected to the main beam 11. The motor is used to drive the sprocket transmission mechanism 4 to move so as to drive the plate pulling manipulator assembly 5 to move along the length of the main beam 11. After the filter component 3 filters the material, the plate pulling manipulator assembly 5 is used to pull the filter plate 31 apart to facilitate the removal of the filter cake.

[0022] The support legs include a first support leg 12 located below the thrust plate 21 and a second support leg 13 located below the hydraulic cylinder 23. The bottom of the first support leg 12 is fixedly connected to a first pad 8, and a number of pre-embedded anchor bolts 81 are connected to the first pad 8. The pre-embedded anchor bolts 81 are used to be embedded in concrete. The bottom of the second support leg 13 is fixedly connected to a second pad 9, and a pre-embedded steel plate 10 is provided below the second pad 9. A number of pre-embedded reinforcing bars 101 are fixedly connected to the bottom of the pre-embedded steel plate 10. The pre-embedded reinforcing bars 101 are used to be embedded in concrete. The thrust plate 21 is the main load-bearing component, which must withstand the high pressure during filtration and pressing. By pre-embedded anchor bolts 81 on the first pad 8 at the bottom of the first support leg 12, the stability of the thrust plate 21 under high pressure is ensured, preventing displacement or tilting, and ensuring accurate positioning of the thrust plate 21, guaranteeing alignment between the pressure plate 22 and the thrust plate 21. A pre-embedded steel plate 10 is installed below the second pad 9 of the second support leg 13, providing support for the second support leg 13. During equipment operation, vibrations and impacts are generated; the pre-embedded steel plate 10 absorbs some of these vibrations and impacts, protecting the oil. The cylinder 23 and related components are not fixed. The second pad 9 is not fixed because the filter plate 31 group may have slight displacement due to uneven material distribution when under pressure. The second support 13 is not fixed, which allows the cylinder 23 and the pressure plate 22 to float slightly, avoids lateral stress concentration, and can automatically adjust the axis of the cylinder 23 to align with the center of the filter plate 31 group, reducing the risk of off-center load. When the cylinder 23 seat and the pressure plate 22 are affected by high temperature materials (such as hot sludge) or the temperature rise of hydraulic oil, local thermal deformation may occur. The non-fixed second support 13 allows them to extend and retract freely to avoid the accumulation of thermal stress that may cause the frame 1 to twist or the weld to crack.

[0023] The sprocket drive mechanism 4 includes a driving sprocket 41, a driven sprocket 42, and a chain 43. The driving sprocket 41 is mounted on the main beam 11 at one end near the pressure plate 22, and the driven sprocket 42 is mounted on the main beam 11 at one end near the thrust plate 21. The driven sprocket 42 and the driving sprocket 41 are connected by the chain 43. Guide rails 111 are mounted on both sides of the main beam 11 along the length direction. The filter plate 31 has locking ears 311 on both the front and rear sides. The plate pulling robot assembly 5 includes a slider 51 and a robot 52 mounted on the slider 51. The slider 51 is mounted on the chain 43 and slidably connected to the guide rail 111. The robot 52 is mounted on the slider 51 and is used to engage with the locking ears 311 to pull the filter plate 31. When the drive sprocket 41 rotates, its teeth mesh with the links of the chain 43. Through the interaction between the teeth and the links, the chain 43 is driven to move. The chain 43 drives the slider 51 to move along the guide rail 111. The robot arm 52 can pull apart each filter plate 31, thereby causing the filter cake in the filter chamber to fall out.

[0024] The thrust plate 21 is provided with a feed inlet 211 that communicates with the filter chamber. The feed inlet 211 is connected to a feed pipe, and a feed valve is installed on the feed pipe. After the feed valve is opened, the material enters each filter chamber from the feed inlet 211 for filtration.

[0025] Each filter plate 31 has a water outlet 312 connected to the filter chamber on both the front and rear sides of its lower part. Each filter plate 31 has a liquid channel at its lower part. The water outlet 312 is connected to the liquid channel. After the material is filtered, the solid remains in the filter chamber, while the liquid is discharged from the water outlet 312 through the liquid channel.

[0026] It also includes a hydraulic system 6 and a control system 7. The hydraulic system 6 includes a hydraulic oil tank, a hydraulic pump, and hydraulic valves. The hydraulic pump draws hydraulic oil from the tank and compresses it to provide pressurized oil to the system. The hydraulic valves include relief valves, directional valves, and throttle valves. The relief valve regulates the system pressure, the directional valve controls the flow of oil to achieve the forward and reverse movement of the actuators, and the throttle valve regulates the oil flow rate to control the movement speed of the actuators. The control system 7 includes a PLC host, which can coordinate the actions of various components to realize automatic feeding, automatic pressing, and automatic cake unloading of the equipment.

[0027] The working principle of this water treatment solid-liquid separation equipment is as follows:

[0028] The hydraulic cylinder 23 pushes the clamping plate 22 to press each filter plate 31. When the pressure reaches the specified value, the pressing process is automatically stopped and the pressure holding state is entered. At this time, a filter chamber is formed between each pair of filter plates 31. The material enters each filter chamber from the feed port 211 on the thrust plate 21. Solid particles are trapped in the filter chamber and form a filter cake. The liquid is discharged from the filter plate 31 from the water outlet 312. After the filtration is completed, the hydraulic cylinder 23 retracts, the clamping plate 22 releases the filter plate 31, and the plate pulling device works. When the drive sprocket 41 rotates, its teeth mesh with the chain links of the chain 43, thereby driving the chain 43 to move. This allows the plate pulling manipulator assembly 5 to move along the guide rail 111. The plate pulling manipulator assembly 5 can pull apart each filter plate 31, so that the filter cake in the filter chamber falls into the corresponding sludge storage hopper below the water treatment solid-liquid separation equipment.

[0029] It should be understood that all the above embodiments are exemplary and not restrictive. Any modifications, equivalent changes and alterations made by those skilled in the art to the specific embodiments described above under the concept of this utility model shall still fall within the scope of the technical solution of this utility model.
