Description

Technical Field

[0001] This utility model relates to the field of resin-based carbon microsphere preparation technology, and in particular to a raw material sieving device for resin-based carbon microspheres. Background Technology

[0002] Resin-based carbon microspheres are tiny spherical structures made of resin materials containing carbon. These microspheres typically possess high specific surface area and porous structure, thus exhibiting excellent adsorption properties and catalytic activity. During preparation, the resin precursor (such as phenolic resin or urea-formaldehyde resin) needs to be sieved to obtain resin particles with a specific particle size distribution, ensuring better control over the particle size and morphology of the carbon microspheres.

[0003] Chinese utility model patent CN212418678U discloses a phenolic resin screening device. Both the first and second motors are connected to an external power source. Material is fed into a conical disc, and through the opening, it falls into a vertical cylinder. The rotation of the inclined plate causes the annularly distributed inclined rods to circulate and move up and down sequentially, thus vibrating the material and preventing false clumping, thereby improving the screening effect. Simultaneously, the circumferential motion of the protrusions causes the rollers to rotate. Through the ring design and the gap between the bottom plate and the transverse groove, the bottom plate can reciprocate left and right under the action of a second spring. Furthermore, through the gap between the ball bearing seat and the movable rod, and the first spring, the box body can irregularly oscillate up and down while reciprocating left and right, thereby improving the screening effect of the filter screen, shortening the working cycle, increasing work efficiency, and making it convenient for users.

[0004] Although the device can effectively sieve materials through the filter screen, in actual use it can only retain large-sized materials according to the filter screen pore size. The sieved material often contains materials smaller than the required particle size, in addition to materials that meet the particle size requirements. Due to the incomplete sieving, the performance of the resin-based carbon microspheres prepared subsequently is affected to a certain extent. Summary of the Invention

[0008] One side of several of the connecting rods is detachably connected to one side of the middle screen frame and the upper screen frame; one side of the screening slide is provided with a power component for driving the lower slide frame to perform reciprocating linear motion.

[0009] In a preferred embodiment of this utility model, the bottom of the sliding frame is slidably connected to the inclined surface of the screening slide, and the sliding frame, the middle screen frame and the upper screen frame are all inclined at the same angle to the inclined surface of the screening slide.

[0010] In a preferred embodiment of the present invention, an intermittent discharge assembly is provided at the bottom of the feeding cone.

[0011] In a preferred embodiment of this utility model, the through groove is coaxially arranged with the feed cone, and the inner diameter of the through groove is the same as the inner diameter of the bottom end of the feed cone.

[0012] In a preferred embodiment of this invention, a plurality of the through slots are circumferentially and evenly distributed on the surface of the turntable.

[0014] In a preferred embodiment of this utility model, the axis of the drive motor is perpendicular to the bottom of the sliding frame, one end of the transmission rod is hinged to the inner side of the hinge block, and the other end is rotatably connected to the top of the drive disk.

[0015] In a preferred embodiment of this utility model, a plurality of bolts are threadedly connected to one side of the connecting rod, and one end of the plurality of bolts is threadedly connected to one side of the middle screen frame and the upper screen frame, respectively.

[0018] This utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0019] (1) This utility model provides a raw material screening device for resin-based carbon microspheres. By setting a screening component on the top of the screening slide, the resin raw material to be screened is placed inside the feed cone. Through the cooperation of the power component, the lower slide frame, the middle screen frame, the upper screen frame, the connecting rod and the screen holes, the raw material that meets the particle size requirements screened by the middle screen frame can be accurately collected, achieving more precise particle size screening. This ensures that the screened resin raw material is within the required particle size range, effectively avoiding the presence of materials smaller than the required particle size in the resin raw material, thereby improving the uniformity and performance consistency of the resin-based carbon microspheres.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0029] like Figure 1 As shown, a raw material screening device for resin-based carbon microspheres includes: a screening slide 1, a screening component disposed on the top of the screening slide 1, and a feed cone 2 disposed on the top of the screening component; the screening component includes: a lower slide frame 3 installed on the inclined surface of the screening slide 1, a middle screen frame 31 and an upper screen frame 32 disposed sequentially on the top of the lower slide frame 3, and a plurality of connecting rods 33 fixed to the side of the lower slide frame 3; the surfaces of the middle screen frame 31 and the upper screen frame 32 are each provided with a plurality of screen holes, the aperture of the screen holes on the surface of the upper screen frame 32 being larger than the aperture of the screen holes on the surface of the middle screen frame 31; one side of the plurality of connecting rods 33 is detachably connected to one side of the middle screen frame 31 and the upper screen frame 32; a power component for driving the lower slide frame 3 to perform reciprocating linear motion is provided on one side of the screening slide 1.

[0030] It should be noted that the bottom of the sliding frame 3 is slidably connected to the inclined surface of the screening slide 1. The sliding frame 3, the middle screen frame 31, and the upper screen frame 32 are all inclined at the same angle to the inclined surface of the screening slide 1. The screen aperture of the upper screen frame 32 is preferably 90 mesh, and the screen aperture of the middle screen frame 31 is preferably 120 mesh. The resin raw material to be screened is placed inside the feed cone 2. At the same time, with the cooperation of the power component, the sliding frame 3 is driven to make reciprocating linear motion on the inclined surface of the screening slide 1. Through the connection of several connecting rods 33, the middle screen frame 31 and the upper screen frame 32 can be driven to move synchronously. After the resin raw material inside the feed cone 2 falls onto the surface of the upper screen frame 32, the generated repeated shaking can screen the resin raw material with a particle size of less than 90 mesh onto the surface of the middle screen frame 31. Furthermore, the middle sieve frame 31 can sieve resin raw materials with a particle size smaller than 120 mesh onto the surface of the lower frame 3, thereby enabling precise collection of raw materials that meet the particle size requirements sieved by the middle sieve frame 31. This achieves more accurate particle size screening, ensuring that the sieved resin raw materials are within the required particle size range, effectively avoiding the presence of materials smaller than the required particle size in the resin raw materials, thereby improving the uniformity and performance consistency of the resin-based carbon microspheres.

[0031] like Figure 2 As shown, in some embodiments, the bottom of the feed cone 2 is provided with an intermittent discharge assembly, which includes: a servo motor 4 fixed to the side of the feed cone 2, a turntable 41 fixed to the output end of the servo motor 4, and a plurality of through slots 42 formed on the surface of the turntable 41; the bottom end of the feed cone 2 contacts the top of the turntable 41.

[0032] It should be noted that the through groove 42 is coaxially arranged with the feed cone 2, and the inner diameter of the through groove 42 is the same as the inner diameter of the bottom end of the feed cone 2. When the resin raw material is put into the feed cone 2, the servo motor 4 is started, which drives the turntable 41 at the output end to rotate. Since the through groove 42 is coaxially arranged with the feed cone 2, and the inner diameter of the through groove 42 is the same as the inner diameter of the bottom end of the feed cone 2, when the through groove 42 on the turntable 41 reaches the bottom of the feed cone 2, the resin raw material can be discharged downward for screening. When it does not reach the bottom of the feed cone 2, the turntable 41 can close the bottom of the feed cone 2, thereby achieving the effect of intermittent discharge of the resin raw material inside the feed cone 2. This avoids the situation where too much resin raw material is put in at one time, which would make it difficult for the upper screen frame 32 to screen quickly and cause the screen holes to be blocked, thus helping to improve the screening efficiency.

[0033] In some embodiments, a plurality of through slots 42 are evenly distributed circumferentially on the surface of the turntable 41; by evenly distributing the plurality of through slots 42 circumferentially on the surface of the turntable 41, a constant intermittent discharge effect can be achieved when the turntable 41 rotates at a constant speed.

[0034] like Figure 3 As shown, in some embodiments, the power assembly includes: a support block 5 fixed to one side of the screening slide 1, a drive motor 51 installed at the bottom of the support block 5, and a drive disk 52 fixed to the top output end of the drive motor 51 located on the support block 5; a hinge block 53 is fixed to one side of the lower slide frame 3, and a transmission rod 54 is provided between the hinge block 53 and the drive disk 52.

[0035] It should be noted that the axis of the drive motor 51 is perpendicular to the bottom of the sliding frame 3. One end of the transmission rod 54 is hinged to the inner side of the hinge block 53, and the other end is rotatably connected to the top of the drive disk 52. The connection between the transmission rod 54 and the drive disk 52 is eccentrically set. When raw material screening is required, the drive motor 51 is started, which drives the drive disk 52 at the output end to rotate. The transmission rod 54, located between the hinge block 53 and the drive disk 52, is hinged to the inner side of the hinge block 53 at one end and rotatably connected to the top of the drive disk 52 at the other end. The connection between the transmission rod 54 and the drive disk 52 is eccentrically set. Thus, when the drive disk 52 rotates, it can repeatedly pull and push the sliding frame 3 through the transmission rod 54, allowing it to slide on the inclined surface of the screening slide table 1, achieving a regular shaking screening effect. This helps to improve the uniformity of the resin material and the screening efficiency during the screening process.

[0036] like Figure 4 As shown, in some embodiments, a plurality of bolts 6 are threadedly connected to one side of the connecting rod 33, and one end of the plurality of bolts 6 is threadedly connected to one side of the middle screen frame 31 and the upper screen frame 32 respectively; the middle screen frame 31 and the upper screen frame 32 are installed on one side of the connecting rod 33 by the plurality of bolts 6, which enables them to be detachably connected, thereby allowing the middle screen frame 31 and the upper screen frame 32 to be replaced, facilitating the control of the screening particle size according to actual needs.

[0037] like Figure 1 As shown, in some embodiments, the side of the lower slide frame 3, the middle screen frame 31, and the upper screen frame 32 facing the bottom of the inclined surface of the screening slide table 1 is conical, and each has a discharge port 7. The resin raw material that falls on the lower slide frame 3, the middle screen frame 31, and the upper screen frame 32 during screening can move towards the bottom of the inclined surface. Since one side is conical, the screened raw material can be gathered at the discharge port 7 and discharged in a concentrated manner, which facilitates the collection operation after screening.

[0038] In some embodiments, the bottom of the screening slide 1 is fixed with a number of support legs 8, and the bottom of the support legs 8 is provided with a number of mounting holes 81. The mounting holes 81 are preferably threaded holes. After the support legs 8 are placed in the working position, the support legs 8 can be fixed in the working position by means of connectors that cooperate with the mounting holes 81, such as screws, so as to provide support and fixation for the whole and help improve stability.

[0039] In use, several support legs 8 are placed in the working position. The support legs 8 are fixed in the working position through the cooperation of the connector and the mounting hole 81. The resin raw material to be screened is placed inside the feed cone 2. The drive motor 51 is started, driving the drive disk 52 at the output end to rotate. The transmission rod 54, located between the hinge block 53 and the drive disk 52, is hinged at one end to the inner side of the hinge block 53 and rotatably connected to the top of the drive disk 52 at the other end. Furthermore, the connection point with the drive disk 52 is eccentrically positioned. Therefore, when the drive disk 52 rotates, it can repeatedly pull and push the sliding frame 3 through the transmission rod 54, allowing it to slide on the inclined surface of the screening slide table 1, achieving a regular... The oscillating sieve simultaneously activates the servo motor 4, which drives the output turntable 41 to rotate. Since the through groove 42 is coaxially set with the feed cone 2 and the inner diameter of the through groove 42 is the same as the inner diameter of the bottom of the feed cone 2, when the through groove 42 on the turntable 41 reaches the bottom of the feed cone 2, the resin raw material can be discharged downwards for sieving. When it does not reach the bottom of the feed cone 2, the turntable 41 can close the bottom of the feed cone 2, thereby enabling intermittent discharge of the resin raw material inside the feed cone 2. After the resin raw material falls onto the surface of the upper screen frame 32, the repeated oscillation generated can sieve the resin raw material with a particle size of less than 90 mesh onto the surface of the middle screen frame 31. Furthermore, the middle screen frame 31 can screen resin raw materials with a particle size of less than 120 mesh onto the surface of the lower screen frame 3, thereby enabling precise collection of raw materials that meet the particle size requirements screened by the middle screen frame 31. The resin raw materials screened onto the lower screen frame 3, the middle screen frame 31, and the upper screen frame 32 can move towards the inclined bottom end during screening. Since one side is conical, the screened raw materials can gather at the discharge port 7 and be discharged in a concentrated manner, thus completing the screening operation.
