Description

Technical Field

[0001] The present application relates to the technical field of filter cloth winding, and more specifically, to a hydraulically driven automatic filter cloth winding mechanism. Background Art

[0002] Sludge dewatering is a critical process in today's industrial and environmental sectors. Sludge contains a large amount of water. If not effectively treated, it not only takes up a significant amount of space but can also cause secondary environmental pollution. Filter cloths are core components of sludge dewatering systems, directly impacting the effectiveness of sludge dewatering. Throughout the dewatering process, filter cloths undergo complex operations, including precise tensioning and movement at various stages of the process.

[0003] In an industrial production environment, ensuring production progress is crucial, which means that filter presses are often in a state of continuous operation. Although this continuous operation mode ensures the continuity of production, it also brings a problem, namely the delay in filter cloth cleaning. Since the filter press is in continuous operation, the filter cloth can only be centrally cleaned after all the filtration processes are completed. During this period, with the advancement of each round of filtration, the impurities remaining on the filter cloth continue to accumulate. These impurities come from various sources and may be solid particles in the material, precipitates produced by chemical reactions, or sticky substances carried by the material itself. As the impurities gradually increase, they begin to clog the pores of the filter cloth, resulting in increased filtration resistance, poor water permeability of the filter cloth, and reduced filtration speed and quality.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; it is obvious that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0029] Reference Figures 1-4 A hydraulically driven filter cloth automatic winding mechanism comprises a filter press box 1, with winding assemblies provided at both ends of the filter press box 1;

[0030] The winding assembly includes a support frame 2, the number of the support frames 2 is set to two groups, the number of each group of support frames 2 is set to two, each group of support frames 2 is provided with a rotating shaft, the outer wall of one of the rotating shafts is fixedly connected to the first rotating roller 3, the outer wall of the other rotating shaft is fixedly connected to the second rotating roller 4, and a filter cloth 6 is provided between the first rotating roller 3 and the second rotating roller 4;

[0031] The cleaning assembly is used to clean the filter cloth 6 after filter pressing, and includes a flushing pipe 10. The flushing pipe 10 is located on one side of the filter cloth 6. One side of the flushing pipe 10 is connected to a plurality of nozzles 12.

[0032] When the two hydraulic motors 11 are started, their output ends respectively drive the rotation shafts inside the first roller 3 and the second roller 4 to rotate. During the filtration process, the two hydraulic motors 11 are not running, and the material is transported to the filter press frame 13 through the feed pipe 7 for filtration. Subsequently, the two hydraulic motors 11 drive the first roller 3 and the second roller 4 to rotate clockwise, causing the filter cloth 6 to move forward and discharge the sludge after filtration. After discharge is completed, the two hydraulic motors 11 drive the first roller 3 and the second roller 4 to rotate counterclockwise, causing the filter cloth 6 to move backward. At this time, the connecting pipe 9 delivers water from the external drive structure to the multiple nozzles 12 of the flushing pipe 10 to clean the filter cloth 6.

[0033] By setting up the winding assembly, the filter cloth roll can be automatically transmitted left and right, the filter cloth 6 can be automatically unfolded and wound, and the tension of the filter cloth 6 can be controlled, which reduces labor costs, improves operating efficiency and also improves the degree of automation of the overall equipment.

[0034] The cleaning assembly provides timely and effective cleaning of the filter cloth 6, preventing the long-term accumulation and drying of sludge on the filter cloth 6. Sludge accumulation can cause the filter cloth 6 to harden, lose its flexibility, or even corrode the material of the filter cloth 6. This cleaning mechanism avoids these problems, ensuring that the filter cloth 6 always maintains good physical and chemical properties, significantly extending the service life of the filter cloth 6 and reducing the frequency and cost of filter cloth 6 replacement.

[0035] Reference Figure 1-Figure 2 A fixed frame 8 is provided on one side of the filter press box 1, and a flushing pipe 10 is installed on the fixed frame 8. A connecting pipe 9 is provided on the top of the flushing pipe 10. A hydraulic motor 11 is provided at one end of the first roller 3 and the second roller 4. The output ends of the two hydraulic motors 11 are fixedly connected to the rotating shafts inside the first roller 3 and the second roller 4 respectively.

[0036] Reference Figure 3-Figure 4The filter cloth 6 is located inside the filter press box 1. A filter press frame 13 is provided on the inner side of the filter press box 1. One end of the filter press frame 13 is connected to a feed pipe 7. Sliders 20 are provided around the filter press frame 13. A plurality of slide rails 19 are provided on the inner side of the filter press box 1. Each slide rail 20 is slidably connected to the corresponding slide rail 19.

[0037] When the material enters the filter press frame 13 through the feed pipe 7, the filter press frame 13 contacts the filter cloth 6 and forms a relatively sealed space with the filter cloth 6 to prevent sludge from flowing out. When the filtration is completed, the slide rail 19 drives the multiple filter press frames 13 on the inner side of the slider 20 to move upward. Because the bottom end of the first electric push rod 14 is slidably connected to the filter press frame 13, the filter press frame 13 will not be affected by the first electric push rod 14 or the pressure plate 15 when it moves upward. At this time, it is convenient to discharge the sludge after filtration.

[0038] Reference Figure 3-Figure 4 The inner side of the filter press frame 13 is slidably connected to the pressure plate 15. The inner top of the filter press box 1 is provided with a first electric push rod 14. The output end of the first electric push rod 14 extends through the interior of the filter press frame 13 and is connected to the pressure plate 15. The bottom end of the first electric push rod 14 is slidably connected to the filter press frame 13. A fixed plate 16 is provided at the bottom of the filter press box 1, and a second electric push rod 17 is provided on the top of the fixed plate 16. The top of the second electric push rod 17 is connected to the support plate 5, and the support plate 5 is slidably connected to the filter press box 1.

[0039] During the filter press operation, the first electric push rod 14 activates and extends, pushing the pressure plate 15 downward within the filter press frame 13. Simultaneously, the second electric push rod 17, located on the fixed plate 16 at the bottom of the filter press box 1, activates and extends, pushing the support plate 5 upward. The support plate 5 is connected to the filter press box 1 in a sliding manner, ensuring the direction of its movement. The downward movement of the pressure plate 15 and the upward movement of the support plate 5 compress the filter cloth 6 sandwiched between the pressure plate 15 and the support plate 5, as well as the material on the filter cloth 6, thus achieving the filter press process and separating the solids and liquids in the material.

[0040] Reference Figure 1-Figure 2 A tension sensor 18 is provided on one side of the first roller 3 and the second roller 4, a controller is provided at one end of the filter press box 1, and the two hydraulic motors 11 and the tension sensor 18 are electrically connected to the controller.

[0041] In this device, tension sensors 18 are located on either side of the first roller 3 and the second roller 4. Their function is to monitor the tension of the filter cloth 6 in real time during the winding and unwinding process. As the filter cloth 6 moves around the first and second rollers 3 and 4, driven by the hydraulic motor 11, the tension of the filter cloth 6 acts on the rollers. The tension sensor 18 senses this force and converts it into an electrical signal.

[0042] These electrical signals are transmitted to a controller located at one end of the filter press 1. The controller has preset parameters for an appropriate tension range. Upon receiving signals from the tension sensor 18, the controller analyzes and processes them. If the tension exceeds or falls below the preset range, the controller sends a command to the hydraulic motor 11, adjusting its speed and thereby changing the winding or unwinding speed of the filter cloth 6, restoring the tension of the filter cloth 6 to within the normal range.

[0043] Working principle: At the beginning, the material enters the filter press frame 13 in the filter press box 1 through the feed pipe 7. The sliders 20 around the filter press frame 13 slide with the slide rails 19 inside the filter press box 1, so that the filter press frame 13 is stably positioned and in close contact with the filter cloth 6, forming a sealed space to prevent sludge leakage.

[0044] Subsequently, the first electric push rod 14 at the top of the filter press box 1 extends, pushing the pressure plate 15 downward within the filter press frame 13. At the same time, the second electric push rod 17 on the bottom fixed plate 16 extends, pushing the support plate 5 upward. As the pressure plate 15 and the support plate 5 move toward each other, the filter cloth 6 and the material sandwiched between them are squeezed, and the solid and liquid in the material are separated, completing the filtration. During this process, the hydraulic motor 11 does not operate.

[0045] After the filtration is complete, the slide rail 19 drives the filter press frame 13 upward. Due to the sliding connection between the first electric push rod 14 and the filter press frame 13, the upward movement does not interfere with the first electric push rod 14 and the pressure plate 15, facilitating material discharge. Next, the hydraulic motor 11 is activated, driving the first and second rollers 3 and 4 to rotate clockwise, driving the filter cloth 6 forward to discharge the filtered sludge.

[0046] After the discharge is completed, the hydraulic motor 11 drives the roller to rotate counterclockwise, moving the filter cloth 6 backward. At the same time, the external water source sends water to the flushing pipe 10 through the connecting pipe 9, and then sprays it through multiple nozzles 12 to clean the filter cloth 6. The above steps are repeated to continuously treat the sludge.

[0047] As the filter cloth 6 is wound and unwound, tension sensors 18 on either side of the first and second rollers 3 and 4 monitor the tension of the filter cloth 6 in real time, converting it into electrical signals and transmitting them to the controller. The controller analyzes and processes these signals based on preset parameters. If the tension is abnormal, it sends a command to the hydraulic motor 11 to adjust its speed to restore the tension of the filter cloth 6 to normal.

[0048] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
