Description

Technical Field

[0001] This utility model relates to the technical field of activated carbon material processing equipment, and in particular to an activated carbon fiber dispersion device. Background Technology

[0002] ACF-nZVI composite materials are widely used in environmental protection fields such as heavy metal wastewater treatment and organic pollutant degradation. The performance of this material is closely related to the uniformity of the loading of nano-zero valent iron on the surface of activated carbon fibers, and the dispersion state of activated carbon fibers during the pretreatment stage will affect this loading effect.

[0003] In the actual preparation process of ACF-nZVI composite material, due to van der Waals forces and surface adsorption forces, activated carbon fiber molecules are prone to aggregate into dense agglomerates. These agglomerates will block the active sites on the surface of activated carbon fibers, significantly reducing their effective contact area with the nano-zero valent iron precursor solution, which in turn leads to uneven loading of nano-zero valent iron, particle agglomeration and growth, and ultimately reduces the adsorption capacity and catalytic reaction efficiency of the composite material.

[0004] Currently used dispersion equipment is mostly general-purpose. During the dispersion process, activated carbon fibers are easily entangled on the surface of the dispersion components, which not only affects the uniformity of dispersion, but also gradually increases the difficulty of cleaning after long-term residue accumulation.

[0005] To address the aforementioned issues, an activated carbon fiber dispersion device is designed that ensures effective dispersion while simultaneously performing cleaning operations to prevent excessive residue. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies, such as the easy entanglement and residue of activated carbon fibers, and the inconvenience of cleaning and collection, by proposing an activated carbon fiber dispersion device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An activated carbon fiber dispersion device includes a frame, with an organic shell fixedly mounted on the top of the frame;

[0009] Two dispersing rollers are rotatably mounted inside the machine housing via bearings. Multiple sets of hooks are fixedly arranged axially on the surface of the dispersing rollers. Each set of hooks consists of multiple hooks arranged in a ring at equal intervals.

[0010] The cleaning roller is rotatably mounted inside the housing via a bearing and located below the dispersing roller. The surface of the cleaning roller has multiple annular grooves along the axial direction, and each annular groove corresponds to a multiple set of hooks.

[0011] The bottom shell is fixedly connected to the bottom of the machine housing and located directly below the cleaning roller;

[0012] The collection box is slidably installed inside the bottom wall of the bottom shell;

[0013] Two horizontal plates are fixed inside the bottom shell. Multiple integrally formed scraper strips are fixed on the top of the horizontal plates, and the multiple scraper strips extend into multiple annular grooves respectively.

[0014] When the two dispersing rollers rotate relative to each other, the hooks pull the activated carbon fiber agglomerates to disperse them, and the cleaning roller and scraper work together to clean the residual fibers on the hooks.

[0015] In one possible design, a geared motor is mounted on the top of the frame, and the shafts of both dispersing rollers rotate through to the outside of the housing and are fixedly fitted with meshing transmission gears. The shaft of one of the dispersing rollers is connected to the output shaft of the geared motor via a coupling.

[0016] In one possible design, a feed hopper is fixedly installed on the top of the casing, the lower end of the feed hopper is connected to the inside of the casing, and discharge pipes are fixedly connected to the bottom of both sides of the casing, through which the dispersed fibers are discharged.

[0017] In one possible design, the hooks are inclined, with the inclination direction consistent with the rotation direction of the dispersing roller, in order to improve the hooking and dispersing effect on fiber agglomerates.

[0018] In one possible design, the inner wall of the annular groove is provided with a soft pad that contacts the rotating barbs and removes residual fibers from the barbs.

[0019] In one possible design, the crossbar is inclined, and the fibers scraped off by the scraper slide down the inclined surface of the crossbar into the collection box.

[0020] In one possible design, a rotating rod is rotatably provided on the side wall of the collection box, and through holes are provided on the side wall of the bottom shell and the housing support. The end of the rotating rod extends through the through hole to the outside and is provided with a handle. A locking plate is fixed on the outer wall of the handle. Rotating the handle causes the locking plate to engage with the housing support, thereby limiting the position of the collection box.

[0021] In this application, during actual use, activated carbon fibers are added from the feed hopper to the middle of the machine casing. At the same time, the geared motor is turned on to drive the corresponding dispersing roller to rotate. Through the meshing transmission gear, another dispersing roller is driven to rotate synchronously. The hooks set on the surface of the dispersing rollers cause the activated carbon fibers falling between the two dispersing rollers to be hooked by the hooks of the two dispersing rollers. When they rotate relative to each other, the fibers are stretched. This cycle continues, causing the hooks to hook the activated carbon fibers, thereby pulling and dispersing the clumps of fibers. The dispersed fibers will then be discharged through the discharge pipe.

[0022] As the dispersing roller continues to rotate, the fibers attached to the hook and barb surface will enter the corresponding annular grooves. At the same time, the cleaning roller will rotate, and the soft pad on the surface of the annular groove will come into contact with the fibers on the relatively rotating hook and barb surface, thereby stripping them off for cleaning. This avoids excessive fiber residue from tangling, which would make it difficult to clean later. As the cleaning roller continues to rotate, it will cooperate with the scraper on the same side, causing the scraper to scrape off the fibers on the soft pad and slide down its inclined surface into the collection box for collection.

[0023] When it is necessary to recycle the fibers inside the collection box, manually rotate the handle to make it rotate the rotating rod and the surface plate, so that the plate rotates to the range of the through hole, thereby releasing the limit of the collection box and pulling it out.

[0024] In this utility model, the activated carbon fiber dispersion device uses two synchronously rotating dispersion rollers in conjunction with inclined hooks to pull and break up the activated carbon fiber agglomerates, thereby ensuring the uniformity of dispersion and guaranteeing the adsorption efficiency in subsequent use.

[0025] In this utility model, the activated carbon fiber dispersion device can achieve fiber recovery by pulling out the collection box without disassembling other parts through a sliding collection box. The operation is simple, and the inclined design of the horizontal plate and scraper makes it easy for the fiber to slide down and be collected, reducing residue.

[0026] In this invention, a cleaning roller corresponding to the hooks of the dispersing roller is provided during use. The annular groove and inner wall pad of the cleaning roller can promptly remove residual fibers from the hooks. Then, the fibers on the pad are scraped off by a scraper, preventing fibers from getting tangled on the dispersing roller and affecting the dispersing operation, thus reducing the frequency and difficulty of equipment maintenance.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0034] In one embodiment: Reference Figure 1 A dispersion device includes: a frame 1, on the top of which a housing 2 is fixedly mounted by bolts, the housing 2 being a hollow cavity structure.

[0035] refer to Figure 2-3 The top of the casing 2 is fixedly equipped with a feed hopper 3, which is funnel-shaped and its lower end is connected to the inside of the casing 2. It is used to feed the activated carbon fiber raw material to be dispersed into the center of the device. The bottom of both sides of the casing 2 are fixedly connected with discharge pipes 4.

[0036] The housing 2 has two dispersing rollers 5 inside, which are arranged in parallel and symmetrically. The two ends of their rotating shafts are rotatably connected to the side wall of the housing 2 through bearings. Multiple sets of hooks 8 are fixedly arranged on the surface of the dispersing rollers 5 along their axial direction. Each set of hooks 8 has multiple hooks arranged in a ring at equal intervals. The hooks 8 are inclined, and the inclination direction is consistent with the rotation direction of the dispersing rollers 5, so as to improve the hooking effect on fiber agglomerates.

[0037] A geared motor 6 is fixedly installed on the top of the frame 1. The shafts of the two dispersing rollers 5 rotate through the outside of the housing 2 and are fixedly fitted with transmission gears 7. The two transmission gears 7 mesh with each other. The shaft of one of the dispersing rollers 5 is fixedly connected to the output shaft of the geared motor 6 through a coupling. The geared motor 6 drives one of the dispersing rollers 5 to rotate, and then drives the other dispersing roller 5 to rotate synchronously in the opposite direction through the meshing transmission gears 7, thereby achieving the pulling and dispersing of fibers.

[0038] refer to Figure 4-5 Inside the housing 2, a cleaning roller 9 is rotatably installed. The cleaning roller 9 is located below the dispersing roller 5. Both ends of its rotating shaft are rotatably connected to the side wall of the housing 2 through bearings. The surface of the cleaning roller 9 has multiple annular grooves 10 along the axial direction. The multiple annular grooves 10 correspond to multiple sets of hooks 8 respectively. The inner wall of the annular groove 10 is fixedly provided with a soft pad. The soft pad is made of elastic rubber material and is used to contact the rotating hooks 8.

[0039] The bottom of the housing 2 is fixedly connected to the bottom shell 11, which is located directly below the cleaning roller 9. A collection box 12 is slidably arranged inside the bottom wall of the bottom shell 11. The collection box 12 is used to collect the fibers cleaned off by the cleaning roller 9. Two horizontal plates 13 are fixedly arranged inside the bottom shell 11. The horizontal plates 13 are inclined. Multiple scraper strips 14 are integrally formed on the top of the horizontal plates 13. The multiple scraper strips 14 extend into the interior of multiple annular grooves 10. The scraper strips 14 are made of hard plastic, and their edges are attached to the soft pads on the inner wall of the annular grooves 10. The cleaning roller 9 is also driven by a motor connected to the outside.

[0040] A rotating rod 15 is rotatably provided on the side wall of the collection box 12. The rotating rod 15 is perpendicular to the side wall of the collection box 12. The side wall of the bottom shell 11 and the bracket of the housing 2 are both provided with through holes 18, which serve as assembly channels for the collection box 12. The end of the rotating rod 15 extends through the through hole 18 to the outside and is fixedly provided with a handle 16. A locking plate 17 is fixedly provided on the outer wall of the handle 16. By rotating the handle 16, the locking plate 17 is rotated, so that the locking plate 17 engages with the bracket of the housing 2, thereby limiting and fixing the collection box 12 inside the bottom shell 11.

[0041] In practical use, the activated carbon fibers to be dispersed are added from the feed hopper 3 to the space between the two dispersing rollers 5 inside the casing 2. At the same time, the reduction motor 6 is turned on, and the reduction motor 6 drives the dispersing roller 5 connected to it to rotate. Through the meshing transmission gear 7, the other dispersing roller 5 is driven to rotate synchronously in the opposite direction. When the dispersing roller 5 rotates, the hooks 8 on its surface hook onto the activated carbon fiber agglomerates that fall between the two rollers. Through the relative rotation of the two rollers, the fibers are pulled, and the agglomerated fibers are gradually stretched and dispersed. The dispersed fibers are discharged through the discharge pipe 4 under their own gravity.

[0042] As the dispersing roller 5 continues to rotate, the residual fibers attached to the hooks 8 on its surface will enter the annular groove 10 of the cleaning roller 9 as the roller rotates. The cleaning roller 9 rotates synchronously, and the soft pad on the inner wall of the annular groove 10 contacts the surface of the hooks 8 that are rotating in the opposite direction, thus removing the residual fibers. The cleaning roller 9 continues to rotate, and the soft pad in the annular groove 10 contacts the scraper 14 on the top of the horizontal plate 13. The scraper 14 scrapes off the fibers attached to the soft pad, and the scraped fibers slide down the inclined horizontal plate 13 into the inside of the collection box 12. By controlling the rotation direction of the cleaning roller 9, the corresponding dispersing roller 5 is cleaned.

[0043] When it is necessary to recycle the fibers in the collection box 12, manually rotate the handle 16. The handle 16 drives the rotating rod 15 and the surface clamping plate 17 to rotate, so that the clamping plate 17 rotates to the range of the through hole 18, releasing the clamping plate 17 from the bracket of the housing 2. Then, the collection box 12 can be pulled out from the bottom shell 11 to complete the fiber recycling. After recycling, the collection box 12 is reset and the handle 16 is rotated in the opposite direction, so that the clamping plate 17 is clamped to the bracket of the housing 2 again, realizing the limitation of the collection box 12.

[0044] This application can be used in the field of activated carbon material processing equipment, or in other fields applicable to this application.

[0045] In another embodiment: an activated carbon fiber dispersion device, which is applied to the field of activated carbon material processing equipment, wherein the discharge pipe 4 can be further connected to a fan, and the negative pressure generated by the fan assists in the discharge, ensuring that the dispersed fibers detach quickly and avoiding secondary agglomeration.

[0046] However, as is well known to those skilled in the art, the working principles and wiring methods of motors and fans are conventional methods or common knowledge, and will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0047] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
