Description

Technical Field

[0001] The invention belongs to the technical field of sludge filter pressing, and in particular relates to a ship-borne filter pressing volume reduction device and an application method thereof. Background Art

[0002] In the practice of river cleaning and environmental protection, the treatment and volume reduction of sludge has always been a key link. As an important equipment for solid-liquid separation, traditional filter presses are widely used in the treatment of river sludge.

[0003] River silt is usually composed of fine particles, organic matter, water, etc., and its physical and chemical properties are complex and changeable. The filter press applies pressure to discharge the water in the silt through the filter medium (such as filter cloth), while the solid particles are trapped on the filter cloth to form a mud cake. In this process, the viscosity, particle size, water content of the silt, and the material and structure of the filter medium will have an important impact on the formation and shedding of the mud cake.

[0004] Highly viscous sludge is more likely to form a solid mud cake on the filter plate, which is difficult to fall off automatically. The uneven size and distribution of particles in the sludge may cause the mud cake to be unevenly distributed on the filter plate, with thicker mud cakes in some areas that are difficult to fall off. Too high or too low a moisture content in the sludge may affect the formation and shedding of the mud cake. Too high a moisture content may cause the mud cake to be too soft and difficult to form a complete structure, while too low a moisture content may make the mud cake too dry, increasing its adhesion to the filter plate. The problem of mud cake residue when unloading by pulling the plate not only affects the filtration efficiency of the filter press, but also brings challenges to equipment maintenance.

DETAILED DESCRIPTION

[0019] Example 1 This embodiment provides a ship-borne filter pressing and volume reduction device, comprising: a filter pressing unit 1, a multi-directional motion unit 2, a positioning unit 3 and a cleaning unit 4.

[0020] The filter press unit 1 includes two groups of filter presses arranged side by side. The filter press is a diaphragm filter press. An operating platform is arranged between the filter presses, and the operating platform is provided for the staff to inspect the working condition of the filter press. The filter press includes at least a frame 11 and a plurality of filter plates 12 slidably arranged on the frame 11. Handles 13 are arranged on both sides of each filter plate 12. The filter press includes at least the following working states: tightening the filter plate 12, feeding and filtering, loosening the filter plate 12, and pulling the plate to unload; that is, the working state of the filter press can be summarized as the pulling plate unloading state or the non-pulling plate unloading state. In this embodiment, each filter press is controlled to be in the pulling plate unloading state and the non-pulling plate unloading state respectively.

[0021] The multi-directional motion unit 2 is arranged above the filter press unit 1. The multi-directional motion unit 2 is used to realize the movement in the X, Y and Z directions. In this embodiment, the X, Y and Z directions are perpendicular to each other. The X direction is set as the length direction of the filter press, the Y direction is perpendicular to the X direction, and the Z direction is vertical to the ground. Figure 1 As shown, the multi-directional motion unit 2 includes: a gantry frame arranged above the filter press, and an X-direction motion component, a Y-direction motion component, and a Z-direction motion component arranged on the gantry frame. The X-direction motion component, the Y-direction motion component, and the Z-direction motion component adopt a linear motion module, which is the prior art and will not be described in detail here.

[0022] The positioning unit 3 is arranged at the output end of the multi-directional motion unit 2, that is, the multi-directional motion unit 2 drives the positioning unit 3 to move in the X, Y, and Z directions. The positioning unit 3 includes a mounting member 31 and two sets of positioning components 32 mirror-imaged on the bottom surface of the mounting member 31. The mounting member 31 is arranged as a bearing plate. The distance between the two sets of positioning components 32 is adjustable.

[0023] like Figure 2 As shown, the cleaning assembly 42 is arranged between the two positioning assemblies 32. The cleaning unit 4 includes several sets of lifting members 41 (the lifting members 41 can be electric push rods, cylinders, etc.) installed on the bottom surface of the mounting member 31, and two sets of cleaning assemblies 42 arranged in a mirror image and connected to the lifting members 41.

[0024] When unloading by pulling the plate, under the drive of the multi-directional motion unit 2, the positioning assembly 32 is arranged close to the current filter plate 12 and clamps and positions the handle portion 13 of the current filter plate 12, separating the current filter plate 12 from the adjacent filter plate 12; When the positioning unit 3 continues to clamp and position the handle portion 13 of the current filter plate 12 , the cleaning assembly 42 is arranged to reciprocate and clean the residual mud cake on the current filter plate 12 under the drive of the lifting member 41 .

[0025] Through the clamping and positioning of the positioning assembly 32, the filter plate 12 remains stable during the cleaning process, avoiding shaking and movement. This enables the cleaning assembly 42 to more effectively remove the mud cake residue on the surface of the filter plate 12, thereby improving the cleaning quality.

[0026] In addition, the two filter presses are equipped with a multi-directional motion unit 2, a positioning unit 3 and a cleaning unit 4, and the two filter presses are allowed to work and clean alternately, thereby maximizing the use of equipment resources. While one filter press is cleaning, the other filter press continues to perform other operations, thereby improving the overall production efficiency.

[0027] In the prior art, the current filter plate 12 is pulled by a plate pulling trolley arranged on both sides of the filter plate 12. However, the plate pulling trolleys on both sides are not an integral structure, but are respectively installed on both sides of the filter plate 12. Since they work independently and lack synchronization and coordination, the following problems often occur in actual operation: since the force or speed of the plate pulling trolleys on both sides when pulling the filter plate 12 is inconsistent, the filter plate 12 will be subjected to uneven force. This unbalanced force condition will cause the filter plate 12 to tilt or deflect during the movement, thereby affecting the accuracy and efficiency of unloading.

[0028] When the filter plate 12 is tilted, the staff needs to spend more time and energy to adjust the position of the filter plate 12 to ensure that it can move smoothly to the designated unloading position. This not only increases the complexity of the operation, but may also reduce the efficiency of the entire production line. The tilt of the filter plate 12 will also increase the wear of the plate pulling trolley and related equipment. Since the filter plate 12 does not move smoothly during the movement, but will shake or jump, this will increase the friction between the plate pulling trolley and the filter plate 12, thereby accelerating the wear and aging of the equipment.

[0029] In order to solve the above problem, in this embodiment, Figure 2 and 3 As shown, each group of positioning components 32 includes: a connecting plate 321, a telescopic member 322, a moving column 323, and a clamping claw 324. The connecting plate 321 is fixed to the bottom surface of the mounting member 31. A telescopic member 322 is arranged on the bottom surface of the connecting plate 321, and the telescopic member 322 is an electric telescopic rod. The top surface of the moving column 323 is slidably connected with the bottom surface of the connecting plate 321, such as using a slide rail or a slider to achieve the sliding connection; the moving column 323 is connected to the output end of the telescopic member 322, and the telescopic member 322 drives the moving column 323 to slide. The clamping claw 324 is installed at the bottom end of the moving column 323. The clamping claw 324 is used to clamp and position the handle part 13. The clamping claw 324 includes two groups of clamping parts in contact with the handle part 13, and the spacing between the two groups of clamping parts is adjustable (such as using a gear rack transmission, pneumatic or other methods, which is a prior art and will not be repeated here), so as to achieve the size change of the positioning space.

[0030] In the non-clamping positioning state, the telescopic member 322 is configured to drive the clamping jaw 324 to approach or move away from the handle portion 13. In the clamping positioning state, the clamping jaw 324 continuously clamps and positions the handle portion 13 to keep the current filter plate 12 stable and immobile.

[0031] When the plate is pulled to unload, the multi-directional motion unit 2 drives the positioning assembly 32 to move or descend for position adjustment, and moves to the vicinity of the current filter plate 12. The telescopic member 322 drives the clamping claw 324 to approach the handle portion 13 to clamp and position the plate pull handle portion 13. Then the multi-directional motion unit 2 drives the positioning assembly 32 to move, driving the current filter plate 12 to separate from the adjacent filter plate 12.

[0032] In this embodiment, the two sets of positioning components 32 are integrated to ensure that the filter plate 12 is subjected to uniform and synchronous clamping force on both sides when the filter plate 12 is pulled, thereby avoiding the problem of the filter plate 12 tilting due to uneven pulling force on both sides. Through the integrated design, the filter plate 12 can remain stable during the movement, reducing the possibility of shaking and offset, thereby improving the accuracy and efficiency of unloading. Since the filter plate 12 remains stable during the movement, the staff does not need to frequently adjust the position of the filter plate 12, thereby simplifying the operation process and reducing labor intensity. The integrated positioning component 32 makes the plate pulling and unloading process smoother and more efficient, which helps to improve the efficiency of the entire production line.

[0033] When the clamping jaws 324 continue to clamp and position the handle portion 13 of the current filter plate 12, the position of the current filter plate 12 is ensured to remain unchanged; the cleaning assembly 42 is reciprocated and lifted under the drive of the lifting member 41 to perform cleaning. A stable filter plate 12 can reduce the areas that are missed due to shaking or displacement; this helps to ensure that all areas on the filter plate 12 are fully cleaned. When the filter plate 12 remains stable, the cleaning assembly 42 moves faster and covers the entire surface of the filter plate 12; this helps to shorten the cleaning time and improve the cleaning efficiency.

[0034] When designing the actual size, the length of the handle portion 13 is lengthened so that when the clamping jaws 324 clamp the handle portion 13 and position it, the cleaning assembly 42 can be lifted and lowered back and forth between the two sets of clamping jaws 324 without causing any obstruction to the cleaning work of the cleaning assembly 42 .

[0035] like Figure 4 and Figure 5 As shown, the cleaning assembly 42 includes: a shielding box body 421, a first bracket 422, a second bracket 423, a driving member, and a plurality of cleaning members 424. The shielding box body 421 is provided with an opening on one side close to the current filter plate 12. The bottom of the shielding box body 421 is provided with an output port 4211, and the output port 4211 is used for the cleaned mud cake to fall out of it.

[0036] like Figure 6As shown, the first bracket 422 is installed inside the shielding box body 421 along the length direction of the shielding box body 421; the two ends of the second bracket 423 are correspondingly connected to the first bracket 422. Part of the second bracket 423 is placed outside the shielding box body 421. The driving member is a driving motor, and its output end is connected to the second bracket 423 for driving the second bracket 423 to rotate. A plurality of groups of cleaning members 424 are installed on the second bracket 423 in an array along the circumferential direction of the second bracket 423. The cleaning member 424 is a cleaning scraper.

[0037] Specifically, Figure 7 As shown, the first bracket 422 includes two groups of support plates 4221 and two groups of connecting rods 4223. The two groups of support plates 4221 are vertically arranged in the shielding box body 421; the support plates 4221 extend upward from a predetermined position (such as the middle position) at the bottom thereof to form a connecting portion 4222. The two ends of each group of connecting rods 4223 are correspondingly connected to the bottom of the two groups of support plates 4221. A hollow space is formed between the connecting rods 4223 and the support portion; the hollow space is located above the output port 4211. The cleaned mud cake can fall from the hollow space and will not accumulate in the shielding box body 421, so as to avoid affecting the rotation of the second bracket 423.

[0038] The second bracket 423 includes: a transmission shaft 4231, two groups of rotating rings 4232 and multiple groups of support rods 4233. The two ends of the transmission shaft 4231 are rotatably connected to the connecting parts 4222 on both sides respectively. Each rotating ring 4232 is connected to one end of the transmission shaft 4231 through multiple groups of support rods 4233. The cleaning member 424 is arranged between the two groups of rotating rings 4232, and the two ends of the cleaning member 424 are connected to the rotating rings 4232 respectively.

[0039] When cleaning the residual mud cake on the surface of the current filter plate 12, first the lifting member 41 drives the cleaning assembly 42 to lift and lower for cleaning, and then the driving member drives the transmission shaft 4231 to rotate, thereby driving the rotating ring 4232 and the cleaning member 424 to rotate. After the cleaning member 424 rotates out of the shielding box body 421, it contacts the surface of the mud cake on the surface of the filter plate 12, scrapes off the mud cake, and completes the mud cake on the current filter plate 12; the scraped mud cake falls from the outside of the shielding box body 421 due to gravity, or is driven by the cleaning member 424 to fall from the output port 4211.

[0040] In the above technical solution, the cleaning piece 424 is in surface contact with the mud cake. Although the surface contact between the cleaning piece 424 and the mud cake means that the contact area is relatively large, this helps the cleaning piece 424 to more effectively apply force to remove the mud cake. However, in some scenarios, the cleaning effect of surface contact is not particularly ideal. For example, a mud cake with high viscosity may be more difficult to scrape off, and a mud cake with too high a water content may form a sliding layer, resulting in the cleaning piece 424 being unable to effectively contact and remove the mud cake. In order to solve this problem, the following technical solution is proposed: Furthermore, if Figure 6 and Figure 8 As shown, the cleaning unit 4 also includes: multiple groups of line cleaning components 43. Among them, the line cleaning components 43 include: a first mounting block 431, a second mounting block 432 and multiple groups of parallel cleaning lines 433. The first mounting block 431 and the second mounting block 432 are respectively installed on different rotating rings 4232. The two ends of the multiple groups of parallel cleaning lines 433 are respectively connected to the first mounting block 431 and the second mounting block 432. When cleaning the residual mud cake on the current filter plate 12, the cleaning line 433 is in a tensioned state.

[0041] By adding the cleaning line 433, the contact mode between the cleaning piece 424 and the mud cake is changed from surface contact to surface contact + line contact. Compared with surface contact alone, when dealing with high-viscosity mud cakes and mud cakes with too high water content, the cleaning line 433 has a certain sharpness and can generate stronger shear force when the cleaning piece 424 rotates. This shear force helps to cut off the fibers or viscous substances in the high-viscosity mud cake, making it easier to scrape off. The cleaning line 433 penetrates the sliding layer of the mud cake with too high water content. This penetration helps to break the sliding layer of the mud cake, allowing the cleaning piece 424 to contact and remove the mud cake more effectively. The setting of the cleaning line 433 significantly improves the cleaning efficiency of the scraper for high-viscosity and high-water-content mud cakes. This helps to reduce cleaning time and labor costs and improve the overall operating efficiency of the equipment.

[0042] The material and surface treatment of the cleaning line 433 reduce the adhesion of the mud cake. By optimizing the material of the cleaning line 433 (such as using wear-resistant, corrosion-resistant, and anti-adhesion materials), the residue of the mud cake on the scraper can be further reduced.

[0043] In addition, the line contact design can reduce the direct wear of the cleaning member 424 on the filter plate 12. Since the cleaning wires 433 are usually made of wear-resistant materials and have a small contact area, they have a relatively low degree of wear on the filter plate 12. This helps to extend the service life of the filter plate 12 and reduce replacement costs.

[0044] The cleaning line 433 is always in a tensioned state, which is achieved by adopting the following technical solutions: Furthermore, if Figure 8 and Fig. 9As shown, the line cleaning assembly 43 also includes: a hollow trough body 434, a rotating column 435, a transmission wheel 436, and a transmission rod 437. The hollow trough body 434 is arranged inside the first mounting block 431. The number of the rotating column 435, the transmission wheel 436, and the transmission rod 437 is the same as that of the cleaning line 433. The rotating column 435 is installed in the hollow trough body 434 (and is rotatably connected to the first mounting block 431), and the rotating column 435 is fixedly connected to one end of the cleaning line 433. One end of the rotating column 435 extends outward through the first mounting block 431 to form an extension. The transmission wheel 436 is installed on the extension. The transmission rod 437 is installed on the first mounting block 431 and is meshed and connected with the transmission wheel 436.

[0045] When the tension of the cleaning line 433 needs to be adjusted, the transmission rod 437 is twisted, and the transmission rod 437 drives the transmission wheel 436 to rotate, thereby driving the rotating column 435 to rotate, and then driving the cleaning line 433 to move, thereby adjusting the tension of the cleaning line 433.

[0046] When the cleaning line 433 is in a tensioned state, the cleaning line 433 can contact the mud cake more effectively and apply enough pressure to remove the mud cake. This enhanced contact pressure helps to cut off the fibers or viscous materials in the mud cake, especially for the high viscosity mud cake.

[0047] The tensioned cleaning line 433 can reduce slippage and deflection during the cleaning process. This helps ensure that the cleaning line 433 always remains in the correct position, thereby removing the mud cake more accurately.

[0048] By adjusting the tension, it is ensured that the cleaning line 433 maintains a stable position during the movement of the scraper. This helps to reduce the risk of poor cleaning effect or equipment damage caused by the deviation of the cleaning line 433.

[0049] The adjustable tension enables the cleaning line 433 to adapt to mud cakes of different properties. For example, for harder mud cakes, the tension can be increased to improve the cleaning effect; while for softer mud cakes, the tension can be appropriately reduced to reduce damage to the equipment.
