Description

Technical Field

[0001] This utility model relates to the field of solid-liquid separation equipment, and more specifically, to a solid-liquid separation device and equipment. Background Technology

[0002] A "solid-liquid separation device" refers to equipment or systems used in industrial processes, environmental engineering, laboratories, and other fields to separate solid particles from liquids in a mixture. Its core purpose is to obtain a clarified liquid (clarified liquid) or a concentrated / dried solid (filter cake), or both.

[0003] Filtration-type solid-liquid separation devices use porous filter media (filter cloth, filter screen, filter element, filter plate, filter bed) to intercept solid particles, allowing liquid to pass through. Currently, filtration-type solid-liquid separation devices on the market usually use fixed filter media, which cannot be reused, and the filter media needs to be removed for cleaning, which is very troublesome.

[0012] In an optional embodiment, the solid-liquid separation device further includes a disassembly and reassembly drive component, which is disposed on the frame and is connected to one of the liquid outlet plates, and is configured to drive the liquid outlet plate to detach from or approach the liquid inlet plate.

[0013] In an optional embodiment, the solid-liquid separation device further includes a limiting component, which is disposed on the frame and abuts against the side of the outlet plate away from the inlet plate after the outlet plate approaches the inlet plate. The limiting component includes a limiting drive and a supporting push rod. The limiting drive is disposed on the frame, and the supporting push rod is operatively connected to the limiting drive. The frame is also provided with a limiting hole, through which the supporting push rod passes, configured to extend out of the limiting hole under the drive of the limiting drive and abut against the side of the outlet plate away from the inlet plate.

[0026] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0027] See Figures 1 to 4The solid-liquid separation device 100 provided in this embodiment of the invention can reuse the circulating filter belt 140 and can clean the circulating filter belt 140 without disassembly, which is very convenient. At the same time, it can achieve automatic cleaning, and has a stable structure with better limiting effect after splicing, achieving the effects of labor saving and automation.

[0028] The solid-liquid separation device 100 provided in this embodiment of the present invention includes a frame 110, an inlet plate 120, an outlet plate 130, a circulating filter belt 140, and a drive roller assembly 150. The frame 110 is a structural support member. The inlet plate 120 and the outlet plate 130 are both mounted on the frame 110. The outlet plate 130 is detachably connected to the inlet plate 120. The top of the inlet plate 120 is provided with an inlet port 121 configured to allow the fluid to be filtered to enter. The outlet plate 130 is provided with an outlet port 131 configured to discharge the filtered fluid. The inlet port 121 and the outlet port 131 are connected. The circulating filter belt 140... Partially disposed between the inlet plate 120 and the outlet plate 130, and the circulating filter belt 140 is configured to filter the liquid to be filtered entering from the inlet 121 when the outlet plate 130 and the inlet plate 120 are joined together; the drive roller assembly 150 is disposed on the frame 110, and the circulating filter belt 140 is wound around the drive roller assembly 150 and distributed in a circulating belt shape between the outlet plate 130 and the drive roller assembly 150. The drive roller assembly 150 is configured to drive the circulating filter belt 140 to rotate cyclically relative to the frame 110 when the outlet plate 130 and the inlet plate 120 are separated, so as to adjust the relative position of the circulating filter belt 140.

[0029] It should be noted that the circulating filter belt 140 is distributed in a circular belt shape, meaning that the circulating filter belt 140 can be connected end to end to form a loop structure, and can rotate cyclically under the drive of the drive roller group 150, thereby adjusting its position relative to the frame 110, so that different sections of the circulating filter belt 140 can rotate sequentially between the inlet plate 120 and the outlet plate 130. Furthermore, the circulating filter belt 140 here is a reusable filter material, such as a filter screen or filter cloth.

[0030] In actual use, first, the clean area of ​​the circulating filter belt 140 is adjusted between the inlet plate 120 and the outlet plate 130. Then, the inlet plate 120 and the outlet plate 130 are joined together. The filtered fluid flows into the inlet plate 120 through the inlet port 121, is filtered by the circulating filter belt 140, enters the outlet plate 130, and is discharged through the outlet port 131. After filtering for a period of time, solid dirt will appear on the surface of the circulating filter belt 140. At this time, the liquid feeding can be stopped, and then the inlet plate 120 and the outlet plate 130 can be disassembled to expose the circulating filter belt 140. Then, the drive roller group 150 drives the circulating filter belt 140 to rotate cyclically relative to the frame 110, so that the dirty area of ​​the circulating filter belt 140 is removed. The clean area of ​​the circulating filter belt 140 is then adjusted between the inlet plate 120 and the outlet plate 130 to continue filtering. The dirty area can be cleaned externally while filtering, realizing the recycling of the circulating filter belt 140.

[0031] In some embodiments, there are two outlet plates 130, which are respectively disposed on both sides of the inlet plate 120. Each outlet plate 130 is provided with an outlet 131, and a circulating filter belt 140 is provided between each outlet plate 130 and the inlet plate 120. Specifically, the two outlet plates 130 are distributed on the left and right sides of the inlet plate 120. The outlet plate 130 on the left side can be fixedly mounted on the frame 110, while the outlet plate 130 on the right side and the inlet plate 120 are movably mounted on the frame 110, thereby enabling the inlet plate 120 and the outlet plates 130 on both sides to be spliced ​​and disassembled.

[0032] It should be noted that the inlet plate 120 here can be a porous structure, made of metal or plastic, with openings on both sides and an inlet 121 at the top, so that the fluid to be filtered flowing into the inlet 121 can be evenly distributed to the outlet plates 130 on both sides, and the two outlet plates 130 can form two filtration drainage channels. Of course, in some other embodiments of this utility model, the outlet plate 130 can also be a single unit, with the inlet plate 120 and the outlet plate 130 spliced ​​together to form a single filtration drainage channel.

[0033] Furthermore, there are two drive roller groups 150 and two circulating filter belts 140. The two circulating filter belts 140 are respectively wound around the two drive roller groups 150. Each drive roller group 150 includes a drive roller 151 and a plurality of first driven rollers 153 spaced apart on the frame 110. The corresponding circulating filter belts 140 are sequentially wound around the drive roller 151 and the plurality of first driven rollers 153 and arranged in a circulating belt shape. The drive roller 151 is configured to drive the circulating filter belts 140 to rotate cyclically. Specifically, the two drive roller groups 150 are symmetrically arranged on the frame 110, and the two circulating filter belts 140 are respectively wound around the two drive roller groups 150. The two circulating filter belts 140 are respectively located between the two liquid outlet plates 130 and the two liquid inlet plates 120, thereby realizing that the two filtration and drainage channels operate independently. At the same time, during cleaning, the two drive rollers 151 can control the movement of the two circulating filter belts 140 respectively.

[0034] In this design, driven rollers 152 are provided on both the upper and lower sides of the safety area of ​​the inlet plate 120 and the outlet plate 130 on the frame 110, thereby ensuring that the circulating filter belt 140 can be threaded between the inlet plate 120 and the outlet plate 130. The drive roller 151 can be driven by a motor to rotate. Both the drive roller 151 and the driven roller 152 are rotatable rollers. The drive roller 151 drives the circulating filter belt 140 to rotate through friction, and the circulating filter belt 140 drives the driven roller 152 to rotate through friction. The winding drive principle between the drive roller 151, the driven roller 152 and the circulating filter belt 140 can be referenced from existing conveyor belt structures.

[0035] In some embodiments, a scraper 160 is further provided on the frame 110. The scraper 160 engages with the filter surface of the circulating filter belt 140. The filter surface is configured to contact the inlet plate 120 and filter out solids in the fluid to be filtered. The scraper 160 is configured to remove solids accumulated on the filter surface. Specifically, there may be two scrapers 160, which scrape the two circulating filter belts 140 respectively. Each scraper 160 may be disposed between two adjacent driven rollers 152 and located on the filter side of the circulating filter belt 140 (i.e., the side where solids accumulate). The scraper 160 can directly contact the filter surface to scrape off the solids. The scraper 160 may be a sheet of iron and may be designed to be detachable for easy replacement and maintenance.

[0036] Furthermore, the solid-liquid separation device 100 also includes a cleaning tank 170, which contains cleaning liquid. A portion of the circulating filter belt 140 is housed within the cleaning tank 170, which is configured to clean the circulating filter belt 140. Specifically, the cleaning tank 170 may contain multiple driven rollers 152 arranged in a triangular pattern to guide the circulating filter belt 140 into the cleaning tank 170 for cleaning. There may be two cleaning tanks 170, located on the left and right sides of the frame 110 respectively, to clean two separate circulating filter belts 140.

[0037] It should be noted that since most of the solids can be scraped off by the scraper 160, the residual dirt on the circulating filter belt 140 can be cleaned in the cleaning tank 170, so that the circulating filter belt 140 can be reused after being cleaned.

[0038] See Figure 1 , Figure 3 , Figure 4 and Figure 5 In some embodiments, the solid-liquid separation device 100 further includes a disassembly / removal drive 180, which is mounted on the frame 110 and is connected to one of the liquid outlet plates 130. The drive 180 is configured to cause the liquid outlet plate 130 to detach from or approach the liquid inlet plate 120. Specifically, the disassembly / removal drive 180 can move the right-side liquid outlet plate 130 relative to the frame 110, thereby separating the liquid outlet plate 130 from the liquid inlet plate 120, facilitating subsequent transfer of the circulating filter belt 140. The disassembly / removal drive 180 can be one of a servo electric cylinder, a pneumatic cylinder, or a hydraulic cylinder.

[0039] Furthermore, a fixing plate 133 is provided on the side of the liquid outlet plate 130 away from the liquid inlet plate 120, and the disassembly and reassembly drive 180 is connected to the fixing plate 133 in a transmission manner. A first transmission pulley 134 is provided at the top of the fixing plate 133, and the first transmission pulley 134 is rolled and engaged with the top side of the frame 110; a second transmission pulley 122 is also provided on the top side of the liquid inlet plate 120, and the second transmission pulley 122 is rolled and engaged with the top side of the frame 110, and is spaced apart from the first transmission pulley 134. Specifically, both the first transmission pulley 134 and the second transmission pulley 122 are passive pulleys. When the fixing plate 133 moves under the drive of the disassembly and reassembly drive, it can drive the fixing plate 133 and the liquid outlet plate 130 to move, thereby causing the first transmission pulley 134 to roll. The liquid inlet plate 120 can be rotated by external force to make the second transmission pulley 122 rotate, thereby causing the liquid inlet plate 120 to disengage from the liquid outlet plate 130 on the left side.

[0040] It should be noted that by setting the first transmission pulley 134 and the second transmission pulley 122 here, more effortless movement can be achieved, making it easier for the plug-in drive component to drive the fixed plate 133 to move.

[0041] In some embodiments, the second transmission pulley 122 can also be driven by a motor, that is, the motor drives the second transmission pulley 122 to rotate, thereby separating the liquid inlet plate 120 from the liquid outlet plate 130 on the left. Of course, the second transmission pulley 122 can also be directly turned by a tool, thereby causing the liquid inlet plate 120 to detach from the liquid outlet plate 130 on the left.

[0042] In some embodiments, the solid-liquid separation device 100 further includes a limiting component 190, which is disposed on the frame 110 and abuts against the side of the outlet plate 130 away from the inlet plate 120 after the outlet plate 130 approaches the inlet plate 120. Specifically, the limiting component 190 can abut against the fixing plate 133 after the outlet plate 130 is joined to the inlet plate 120, thereby keeping the outlet plate 130 and the inlet plate 120 in a joined state. By additionally designing the limiting component 190, auxiliary support can be provided for the disassembly and reassembly drive component 180, ensuring the stability of the joined state.

[0043] Furthermore, the limiting assembly 190 includes a limiting drive 191 and a holding push rod 192. The limiting drive 191 is mounted on the frame 110, and the holding push rod 192 is connected to the limiting drive 191. The frame 110 is also provided with a limiting hole 193, through which the holding push rod 192 passes. It is configured to extend out of the limiting hole 193 under the drive of the limiting drive 191 and abut against the side of the liquid outlet plate 130 away from the liquid inlet plate 120. Specifically, the limiting drive 191 can be a servo electric cylinder, a pneumatic cylinder, or a hydraulic cylinder. The holding push rod 192 is arranged in a direction perpendicular to the movement of the liquid outlet plate 130 and abuts against the fixed plate 133. The vertical direction is used to achieve the abutment, and with the limiting effect of the limiting hole 193, the driving force of the limiting drive 191 and the disassembly drive 180 can be removed after the abutment is in place. This allows the liquid outlet plate 130 in the spliced ​​state to be fixed with less force, achieving the effects of energy saving and automation.

[0044] The solid-liquid separation device 100 provided in this embodiment of the present invention, in use, first moves a clean circulating filter belt 140 between the inlet plate 120 and the outlet plate 130. Then, using the disassembly and assembly drive component 180, the fixing plate 133 and the right-side outlet plate 130 are pushed to the left, pressing the inlet plate 120 together. Driven by the first transmission pulley 134 and the second transmission pulley 122, the outlet plate 130 and the inlet plate 120 are spliced ​​together. After merging, they are held in place by the abutment of the push rod 192, thus allowing the outlet plate 130 and the inlet plate 120 to be fixed with relatively small force. After assembly, the fluid to be filtered, containing solids, enters the inlet plate 120 through the inlet port 121. Then, the solids in the fluid are left on one side of the circulating filter belt 140, and the filtered fluid enters the outlet plate 130 and is discharged from the outlet port 131. After long-term use, a lot of solids will accumulate on the circulating filter belt 140, which needs to be cleaned regularly. At this time, the disassembly and reassembly drive 180 to drive the outlet plate 130 to detach from the inlet plate 120, so that the circulating filter belt 140 is in a free state. Then, the drive roller 151 drives the circulating filter belt 140 to rotate. The dirty circulating filter belt 140 moves downward and the solids are scraped off by the scraper 160. Then, it is washed clean by the cleaning tank 170 to achieve the effect of reuse. At the same time, the clean part of the circulating filter belt 140 moves back between the inlet plate 120 and the outlet plate 130 for the next round of filtration.

[0045] See Figure 6This utility model embodiment also provides another solid-liquid separation device 100, whose basic structure, principle, and technical effects are the same as the aforementioned solid-liquid separation device 100. For the sake of brevity, any parts not mentioned can be referred to the foregoing content. The solid-liquid separation device 100 provided in this utility model embodiment has two circulating filter belts 140. The drive roller group 150 includes an active roller 151, a plurality of first driven rollers 153, and a plurality of second driven rollers 154 spaced apart on the frame 110. The two circulating filter belts 140 are respectively wound around the plurality of first driven rollers 153 and the plurality of second driven rollers 154, and the two circulating filter belts 140 overlap and are wound around the active roller 151 in a circulating belt shape. The active roller 151 is configured to drive the two circulating filter belts 140 to rotate cyclically. Specifically, the active roller 151 is located at the upper left corner of the frame 110, the cleaning tank 170 is a single unit, multiple first driven rollers 153 are located on the left side of the frame 110, forming a single circulation loop with the active roller 151, and multiple second driven rollers 154 are located on the right side of the frame 110, also forming a single circulation loop with the active roller 151. Two circulating filter belts 140 overlap and enter the cleaning tank 170 for cleaning, simultaneously driven by the active roller 151, before winding onto the multiple first driven rollers 153 and multiple second driven rollers 154 respectively, thus achieving a two-way filtration loop. Two scrapers 160 are also used to clean the two circulating filter belts 140. By using the same cleaning tank and the same active roller 151 for driving, the overall structure is simplified and materials are saved.

[0046] See Figure 7This utility model embodiment also provides another solid-liquid separation device 100, whose basic structure, principle, and technical effects are the same as the aforementioned solid-liquid separation device 100. For the sake of brevity, any omissions can be referred to the foregoing content. The solid-liquid separation device 100 provided in this utility model embodiment has one circulating filter belt 140. The drive roller group 150 includes an active roller 151, multiple first driven rollers 153, and multiple second driven rollers 154 spaced apart on the frame 110. The circulating filter belt 140 is sequentially wound around the active roller 151, the multiple first driven rollers 153, and the multiple second driven rollers 154, arranged in a circulating belt shape. The active roller 151 is configured to drive the circulating filter belt 140 to rotate cyclically. Specifically, there can be two scrapers 160, which perform secondary scraping of the circulating filter belt 140, resulting in better cleaning. The circulating filter belt 140 is driven by the drive roller 151. It first passes through multiple second driven rollers 154 and runs between the outlet plate 130 and inlet plate 120 on the right side. Then it passes through multiple first driven rollers 153 and runs between the outlet plate 130 and inlet plate 120 on the left side before entering the cleaning tank for cleaning. Finally, it returns to the drive roller 151. By using a single circulating filter belt 140, the overall structure is simplified, making the driving process of the circulating filter belt 140 more concise and efficient, and saving costs.

[0047] This utility model also provides a solid-liquid separation device, including an inlet pipe, an outlet pipe, and a solid-liquid separation device 100 as described above. The solid-liquid separation device 100 includes a frame 110, an inlet plate 120, an outlet plate 130, a circulating filter belt 140, and a drive roller assembly 150. The frame 110 is a structural support member. The inlet plate 120 and the outlet plate 130 are both mounted on the frame 110. The outlet plate 130 is detachably connected to the inlet plate 120. The top of the inlet plate 120 is provided with an inlet port 121 configured to allow the fluid to be filtered to enter. The outlet plate 130 is provided with an outlet port 131 configured to discharge the filtered fluid. The inlet port 121 and the outlet plate 130 are connected together.

[0048] In summary, the solid-liquid separation device 100 and equipment provided in this embodiment of the present invention are provided with a detachable and spliced ​​liquid outlet plate 130 and a liquid inlet plate 120 on the frame 110. The liquid outlet plate 130 has a liquid outlet 131 for discharging the filtered fluid, and the liquid inlet plate 120 has a liquid inlet 121 for the fluid to be filtered to enter. The circulating filter belt 140 is partially disposed between the liquid inlet plate 120 and the liquid outlet plate 130, and can achieve the filtration function when the liquid outlet plate 130 and the liquid inlet plate 120 are spliced ​​together, filtering the filtered liquid entering through the liquid inlet 121 and discharging it through the liquid outlet 131. The frame 110 is also equipped with a drive roller assembly 150. The circulating filter belt 140 is wound around the drive roller assembly 150 and distributed in a circulating belt shape between the liquid outlet plate 130 and the drive roller assembly 150. The drive roller assembly 150 can drive the circulating filter belt 140 to rotate relative to the frame 110 when the liquid outlet plate 130 and the liquid inlet plate 120 are separated, thereby adjusting the relative position of the circulating filter belt 140.

[0049] In actual use, first, the clean area of ​​the circulating filter belt 140 is adjusted between the inlet plate 120 and the outlet plate 130. Then, the inlet plate 120 and the outlet plate 130 are joined together. The filtered fluid flows into the inlet plate 120 through the inlet port 121, is filtered by the circulating filter belt 140, enters the outlet plate 130, and is discharged through the outlet port 131. After filtering for a period of time, solid dirt will appear on the surface of the circulating filter belt 140. At this time, the liquid feeding can be stopped, and then the inlet plate 120 and the outlet plate 130 can be disassembled to expose the circulating filter belt 140. Then, the drive roller group 150 drives the circulating filter belt 140 to rotate cyclically relative to the frame 110, so that the dirty area of ​​the circulating filter belt 140 is removed. The clean area of ​​the circulating filter belt 140 is then adjusted between the inlet plate 120 and the outlet plate 130 to continue filtering. The dirty area can be cleaned externally while filtering, realizing the recycling of the circulating filter belt 140.

[0050] Compared to existing technologies, the solid-liquid separation device 100 provided in this embodiment of the invention can reuse the circulating filter belt 140 and can automatically clean the circulating filter belt 140 without disassembling it, which is very convenient. Furthermore, the cleaning of the circulating filter belt 140 is achieved using a scraper 160 and a cleaning tank, resulting in better cleaning performance. The push rod 192, after passing through the limiting hole 193 on the frame 110, abuts against the fixing plate 133, allowing for the fixation of the liquid outlet plate 130 in its assembled state with less force, achieving energy saving and automation.
