Description

Technical Field

[0001] This invention relates to the technical field of mud dewatering and solidification devices, specifically a mobile mud dewatering and solidification device. Background Technology

[0002] The core functions of mud dewatering and solidification are volume reduction, harmlessness, resource utilization, cost reduction and efficiency improvement, and environmental compliance. It can transform mud with high water content, easy pollution, and difficult disposal into transportable, usable, and low-risk solid materials. It can also achieve significant volume reduction, reduce transportation and disposal costs, and reduce the water content of mud from 75%–95% to 20%–60%, reducing the volume by half.

[0003] Mud dewatering and solidification are mostly accomplished using filter presses. The filter cloth, in conjunction with an internal expanding membrane, forces water out of the mud. However, under high pressure, the dried mud slab adheres tightly to the filter cloth surface, and some mud seeps into the pores of the cloth. This prevents the mud slab from falling off automatically during demolding, requiring workers to use metal shovels to clean the remaining mud slab inside the equipment. To address these problems, this invention proposes the following technical solution. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a mobile mud dewatering and solidification device, including a support frame, a hydraulic push rod fixedly connected to the side wall of the support frame, a flow pipe fixedly connected to the end of the support frame away from the hydraulic push rod, a pressure plate fixedly connected to the output end of the hydraulic push rod, a plurality of filter plates slidably connected to the top outer wall of the support frame, an expansion bladder fixedly connected to the inner wall of the filter plates, and a filter cloth fixedly connected to the inner wall of the filter plates, and further comprising: The closing mechanism is fixedly installed on the side wall of the filter press plate; The crushing mechanism is rotatably mounted on the inner wall of the closing mechanism; A limiting mechanism is installed on the outer wall of the closing mechanism to restrict its rotation. Several filter press plates are arranged horizontally on the top of the support frame. Before use, the hydraulic push rod presses the filter press plates together with the pressure plate. The external high-pressure pump injects slurry into the gap between the two filter press plates through the through hole in the center of the filter press plate. Then, the flow pipe injects water into the gap between the filter press plates and forces the expansion bladder to expand, removing the water from the slurry inside the gap.

[0005] Preferably, the closing mechanism includes: The inner plate assembly is fixedly installed on the side wall of the filter press plate; The outer panel assembly is fixedly installed on the side of the filter press plate away from the inner panel assembly; When the two filter press plates approach each other, the inner plate assembly of one of the filter press plates will be inserted into the inner wall of the outer plate assembly. After the inner plate assembly and the outer plate assembly are completely pressed together, a sealed environment will be formed, and the water inside the two filter press plates can only be discharged outward through a fixed path.

[0006] Preferably, the crushing mechanism includes: The meshing assembly is rotatably disposed on the inner wall of the inner plate assembly; A rolling assembly is rotatably mounted on the inner wall of the inner panel assembly. The outer surfaces of the meshing and rolling components are lower than the outer surface of the inner plate components.

[0007] Preferably, the limiting mechanism includes: A tensioning component is fixedly mounted on the side wall of the engaging component; A sliding component is fixedly installed on the side wall of the inner panel component; The outer panel assembly has a notch on its side wall, and the tensioning assembly will be in the notch position when the two filter plates overlap.

[0008] Preferably, the inner plate assembly includes a first outer partition plate fixedly connected to the side wall of the filter press plate, and a first inner partition plate fixedly connected to the side of the filter press plate near the first outer partition plate. The thickness of the inner partition panel is lower than that of the outer partition panel, and the outer surface of the inner partition panel is rounded.

[0009] Preferably, the outer panel assembly includes a second partitioned outer panel fixedly connected to the side of the filter press plate away from the inner panel assembly, and a second partitioned inner panel fixedly connected to the side of the filter press plate near the second partitioned outer panel. When the two filter plates are closed, the second inner partition plate will be tightly attached to the outer wall of the first inner partition plate, and the two will be tightly fitted together, so that a forming space is formed between the two filter plates.

[0010] Preferably, the meshing assembly includes a roller rod rotatably connected to the inner wall of the outer partition plate, and a gear is fixedly connected to the side wall of the roller rod. Among them, the center of the roller is slightly thicker, and there are two sets of meshing components and rolling components, which are symmetrically distributed vertically.

[0011] Preferably, the rolling assembly includes a roller rod 2 rotatably connected to the inner wall of the outer partition plate, a gear 2 fixedly connected to the outer wall of the roller rod 2, a belt sleeved on the outer wall of the roller rod 2, and a filter screen fixedly connected to the side wall of the belt; The belt is sleeved on the outer wall of the upper and lower sets of rollers, and the outer wall of the second gear meshes with the outer wall of the first gear. The holes of the filter screen are much larger than the filter holes of the filter cloth, and the filter screen is made of rubber, which can achieve large-angle rotation and stretching deformation.

[0012] Preferably, the pulling assembly includes a sprocket fixedly connected to the outer wall of the second roller, and a toothed chain is engaged with the outer wall of the sprocket; One end of the toothed chain is fixedly connected to the outer wall of another filter press plate.

[0013] Preferably, the sliding assembly includes a track fixedly connected to the outer wall of the filter press plate, and a slider slidably connected to the inner wall of the track; The bottom of the slider is fixedly equipped with a spring, and the slider is normally in a retracted state.

[0014] The present invention has the following beneficial effects: (1) In view of the problem that the mud plate cannot fall off on its own, the present invention has a crushing mechanism and a restraining mechanism inside the equipment. During the mud plate forming process, part of the mud plate will be wrapped around the outer wall of the filter screen. When the two filter plates are separated, the deformed filter screen will move towards the outer wall of the filter screen. Figure 7 The state change occurs, and the mud plate attached to the outer wall of the filter screen will be pulled away from the outer wall of the filter cloth by the filter screen. Through the application of the above components, the molded mud plate is forced to quickly detach from the outer wall of the filter cloth under the pull of the filter screen, thereby improving the demolding efficiency.

[0015] (2) This invention utilizes the characteristic of filter plates separating during demolding. When the distance between two adjacent filter plates increases, one of the filter plates will drive one end of the toothed chain to move, forcing the toothed chain to drive the sprocket and roller rod two to rotate. The rotating roller rod two will drive the internal belt and filter screen to rotate in the same direction, forcing the filter screen to move from the mold. Figure 7 The state changes to Figure 10 In this process, because the mud plate is relatively hard, when the belt and filter screen carry the mud plate to the two corner positions of the roller, the hard mud plate cannot rotate, and the filter screen is pulled away from the mud plate by the belt. After the filter screen loses its restraint on the mud plate, the mud plate will fall downward on its own.

[0016] (3) In view of the problem that some mud blocks are stuck when the filter screen is detached from the mud blocks, the present invention has a crushing mechanism inside the equipment. When the filter screen carries the mud blocks past the positions of roller rod one and roller rod two, the mud blocks will be crushed into thin sheets. As the distance between the filter plates increases, the thin sheets will pass the position of the inner partition plate one and be subjected to scraping force, resulting in the phenomenon of falling off. Through the application of the above components, excessive mud blocks are prevented from sticking to the outer wall of the filter screen and affecting the effective volume of the cavity of the two filter plates combination.

[0017] (4) The present invention utilizes the above-mentioned crushing mechanism to reciprocate pressing the filter screen. After removing a large number of flaky mud pieces, a large number of powdery impurities remain on the outer wall of the filter screen. These impurities will adhere to the outer wall of the filter screen. When the subsequent equipment performs mud dewatering for the second time, the mud plate formed will wrap the filter screen again. The powdery impurities on the outside of the filter screen will reduce the wrapping effect of the mud plate on the filter screen and accelerate the subsequent demolding efficiency.

[0022] Example 1, please refer to Figure 1 - Figure 9 This invention relates to a mobile mud dewatering and solidification device, comprising a support frame 13, a hydraulic push rod 14 fixedly connected to the side wall of the support frame 13, a flow pipe 15 fixedly connected to the end of the support frame 13 away from the hydraulic push rod 14, a pressure plate 16 fixedly connected to the output end of the hydraulic push rod 14, a plurality of filter plates 17 slidably connected to the top outer wall of the support frame 13, an expansion bladder 18 fixedly connected to the inner wall of the filter plates 17, and a filter cloth 19 fixedly connected to the inner wall of the filter plates 17.

The external high-pressure pump injects slurry into the gap between two filter plates 17 through the through hole in the center of the filter plate 17. Then, the flow pipe 15 injects water into the gap of the expansion bladder 18 and forces the expansion bladder 18 to expand, removing the water from the slurry inside the gap. After the slurry dewatering is completed, the moving claw at the top of the support frame 13 drives the filter plates 17 to separate one by one.

[0023] Closing mechanism 1 includes: Inner plate assembly 11 is fixedly disposed on the side wall of filter press plate 17; The outer panel assembly 12 is fixedly disposed on the side of the filter press plate 17 away from the inner panel assembly 11; When the two filter press plates 17 approach each other, the inner plate assembly 11 of one of the filter press plates 17 will be inserted into the inner wall of the outer plate assembly 12. After the inner plate assembly 11 and the outer plate assembly 12 are completely pressed together, a sealed environment will be formed, and the water inside the two filter press plates 17 can only be discharged outward through a fixed path.

[0024] Crushing mechanism 2 includes: Engaging assembly 21 is rotatably disposed on the inner wall of inner plate assembly 11; Rolling assembly 22 is rotatably disposed on the inner wall of inner plate assembly 11; The outer surfaces of the meshing assembly 21 and the rolling assembly 22 are lower than the outer surface of the inner plate assembly 11.

[0025] Restricted agency 3 includes: Pulling component 31 is fixedly disposed on the side wall of engaging component 21; Sliding component 32 is fixedly disposed on the side wall of inner plate component 11; The outer panel assembly 12 has a notch on its side wall, and when the two filter plates 17 overlap, the pulling assembly 31 will be in the notch position.

[0026] Example 2, please refer to Figure 4 - Figure 15 The present invention is a mobile mud dewatering and solidification device. Based on Example 1, the inner plate assembly 11 includes a partition outer plate 111 fixedly connected to the side wall of the filter press plate 17, and a partition inner plate 112 fixedly connected to the side of the filter press plate 17 near the partition outer plate 111. The thickness of the inner partition plate 112 is lower than that of the outer partition plate 111, and the outer surface of the inner partition plate 112 is rounded.

[0027] The outer panel assembly 12 includes a second outer partition plate 121 fixedly connected to the side of the filter press plate 17 away from the inner panel assembly 11, and a second inner partition plate 122 fixedly connected to the side of the filter press plate 17 near the second outer partition plate 121. When the two filter plates 17 are closed, the second partition plate 122 will be tightly attached to the outer wall of the first partition plate 112, and the two will be tightly fitted together, so that a forming space is formed between the two filter plates 17.

[0028] The meshing assembly 21 includes a roller rod 211 rotatably connected to the inner wall of the outer partition plate 111, and a gear 212 is fixedly connected to the side wall of the roller rod 211. Among them, the center of the roller pressure bar 211 is slightly thicker, and the meshing component 21 and the rolling component 22 are two sets, which are symmetrically distributed vertically.

[0029] The rolling assembly 22 includes a roller 221 rotatably connected to the inner wall of the outer partition plate 111, a gear 222 fixedly connected to the outer wall of the roller 221, a belt 223 sleeved on the outer wall of the roller 221, and a filter screen 224 fixedly connected to the side wall of the belt 223. Under normal conditions, filter 224 will be in Figure 7 In the state where the inner panel assembly 11 and the outer panel assembly 12 are in close contact, the filter screen 224 will be in the gap between the inner panel 2 122 and the inner panel 1 112, and at this time, part of the filter screen 224 will be in a state of being stretched.

[0030] The tensioning assembly 31 includes a sprocket 311 fixedly connected to the outer wall of the roller bar 221, and a toothed chain 312 meshing with the outer wall of the sprocket 311. To address the issue of the mud plates failing to fall off independently, a crushing mechanism 2 and a restraining mechanism 3 are installed inside the equipment. During the mud plate forming process, part of the mud plate will wrap around the outer wall of the filter screen 224. When the two filter plates 17 separate, the deformed filter screen 224 will... Figure 7 The state change occurs, and the mud plate attached to the outer wall of the filter screen 224 will be pulled away from the outer wall of the filter cloth 19 by the filter screen 224. Through the application of the above components, the molded mud plate is forced to quickly detach from the outer wall of the filter cloth 19 under the pull of the filter screen 224, thereby improving the demolding efficiency.

[0031] The sliding assembly 32 includes a track 321 fixedly connected to the outer wall of the filter plate 17, and a slider 322 slidably connected to the inner wall of the track 321. Taking advantage of the separation of filter plates 17 during demolding, as the distance between two adjacent filter plates 17 increases, one of the filter plates 17 will drive one end of the toothed chain 312 to move, forcing the toothed chain 312 to drive the sprocket 311 and the roller 221 to rotate. The rotating roller 221 will then drive the internal belt 223 and the filter screen 224 to rotate in the same direction, forcing the filter screen 224 to... Figure 7 The state changes to Figure 10 In this process, because the mud plate is relatively hard, when the belt 223 and the filter screen 224 carry the mud plate to the corner position of the roller 221, the hard mud plate cannot rotate. The filter screen 224 is pulled off the mud plate by the belt 223, and after the filter screen 224 loses its restraint on the mud plate, the mud plate will fall downward on its own.

[0032] A specific application of this embodiment is as follows: Before use, the equipment is first installed on a mobile carrier. Then, the hydraulic push rod 14 presses several filter plates 17 together tightly through the pressure plate 16. An external high-pressure pump injects slurry into the gap between two filter plates 17 through the through hole in the center of the filter plate 17. Figure 7 As shown in position K, the flow pipe 15 injects water into the gap of the expansion bladder 18 and forces the expansion bladder 18 to expand, removing the water from the mud inside the gap. After the mud dewatering is completed, the moving claws at the top of the support frame 13 drive the filter press plates 17 one by one to separate them. Among them, under normal conditions, filter 224 will be in Figure 7 In the state where the inner panel assembly 11 and the outer panel assembly 12 are in close contact, the filter screen 224 will be in the gap between the inner panel 2 122 and the inner panel 1 112, and at this time, part of the filter screen 224 will be in a state of being stretched. To address the issue of the mud plates failing to fall off independently, a crushing mechanism 2 and a restraining mechanism 3 are installed inside the equipment. During the mud plate forming process, part of the mud plate will wrap around the outer wall of the filter screen 224. When the two filter plates 17 separate, the deformed filter screen 224 will... Figure 7 The state change occurs, and the mud plate attached to the outer wall of the filter screen 224 will be pulled away from the outer wall of the filter cloth 19 by the filter screen 224. Through the application of the above components, the molded mud plate is forced to quickly detach from the outer wall of the filter cloth 19 under the pull of the filter screen 224, thereby improving the demolding efficiency. Taking advantage of the separation of filter plates 17 during demolding, as the distance between two adjacent filter plates 17 increases, one of the filter plates 17 will drive one end of the toothed chain 312 to move, forcing the toothed chain 312 to drive the sprocket 311 and the roller 221 to rotate. The rotating roller 221 will then drive the internal belt 223 and the filter screen 224 to rotate in the same direction, forcing the filter screen 224 to... Figure 7 The state changes to Figure 10 In this process, because the mud plate is relatively hard, when the belt 223 and the filter screen 224 carry the mud plate to the corner position of the roller 221, the hard mud plate cannot rotate. The filter screen 224 is pulled off the mud plate by the belt 223, and after the filter screen 224 loses its restraint on the mud plate, the mud plate will fall downward on its own.

[0033] To address the issue of some mud lumps sticking together when the filter screen 224 detaches from the mud, a crushing mechanism 2 is installed inside the equipment. When the filter screen 224 carries mud lumps past the positions of roller 1 211 and roller 2 221, the mud lumps are crushed into thin sheets. As the distance between the filter plates 17 increases, the thin sheets pass the position of the inner partition plate 112 and are subjected to scraping force, causing them to fall off. Through the application of the above components, excessive mud lumps are prevented from sticking to the outer wall of the filter screen 224, thus affecting the effective volume of the cavity of the two filter plates 17.

[0034] By using the above-mentioned crushing mechanism 2 to reciprocate the pressing of the filter screen 224, after removing a large number of flaky mud flakes, a large number of powdery impurities remain on the outer wall of the filter screen 224. These impurities will adhere to the outer wall of the filter screen 224. When the subsequent equipment performs mud dewatering for the second time, the mud plate formed will wrap around the filter screen 224 again. The powdery impurities on the outside of the filter screen 224 will reduce the wrapping effect of the mud plate on the filter screen 224, thus accelerating the subsequent demolding efficiency. When the filter plates 17 approach each other, the spring at the bottom of the slider 322 will drive the slider 322 to slide down along the track 321, and force the toothed chain 312 to drive the sprocket 311 and the crushing mechanism 2 to reset.
