Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of material screening, and in particular to a material screening device and method for diluent production. BACKGROUND

[0002] Diluent is a chemical substance used to reduce the viscosity of a substance and adjust its concentration. Its core function is to improve the processing performance or use effect of materials by dissolving or dispersing other components. It is widely used in fields such as coatings, adhesives, inks, and chemical extraction. In the production process of diluent, solid materials are often used as additives or auxiliary components to improve product performance, adjust process parameters, or meet specific application requirements.

[0003] The solid raw materials used in the production of diluent are mostly solid powders, such as antioxidants, thickeners, and conductive agents. The particle size of these powders directly affects the physical and chemical properties of the product in actual production and application. Therefore, they need to be screened by a screening device to separate them according to their particle size, and then applied differently according to their particle size to achieve higher usage.

[0040] Specific, the support seat 101 is used for supporting the whole device, the cover guide cylinder 103 arranged on the top of the screening main box 102 is provided with a corresponding sealing cover, so that the top of the screening main box 102 can be sealed after the addition of the material is completed, and meanwhile the cover guide cylinder 103 can also be replaced by a guide-in inner feeding structure to realize the continuous feeding of the material and the sealing of the whole device.

[0041] A plurality of installation grooves for cooperating with the loading members are arranged on the side of the screening main box 102, each group of the loading members can be provided with a group of the loading racks 104 and the filter screen plates 105, two installation openings for fixing the filter screen plates 105 are arranged on each loading rack 104, and a knocking transverse area for subsequent cooperation with other structures is reserved in the middle of the loading rack 104, the top of the reserved area in the middle of the loading rack 104 can be provided with a structure inclined on two sides, so that the material can flow more quickly towards the filter screen plates 105 on the two sides, and the material can be prevented from accumulating in the middle of the loading rack 104.

[0042] The screening main box 102 is provided with an inclined table, and the bottom of the screening main box 102 is also provided with plug cavities for cooperating with two plug pulling racks 106, a partition plate is arranged between the two plug cavities to block the two plug pulling racks 106, so that the movement of the two plug pulling racks 106 will not interfere with each other, and corresponding material guide openings are arranged on the side of the two plug cavities, the powder material falling to the bottom of the screening main box 102 can be discharged through the material guide openings.

[0043] In actual operation, the user can first select the filter screen plate 105 according to the actual screening requirements, then install the loading frame 104 with the corresponding filter screen plate 105 into the screening main box 102 through the loading member, after the installation of the loading frame 104 and the filter screen plate 105 is completed, the powder solid material to be screened is introduced through the cover guide cylinder 103 arranged at the top of the screening main box 102, and the bottom of the cover guide cylinder 103 needs to be closed and sealed after the powder solid material is introduced. After the material is introduced, the multi-layer filter screen plate 105 arranged inside the screening main box 102 is used for multi-level rapid screening, at this time, the two plugger frames 106 arranged at the bottom of the screening main box 102 will move alternately under the drive of the plugger frame 106, and the two alternating plugger frames 106 cooperate with the opening and closing control member to generate continuous downward airflow in the screening main box 102, so that the powder solid material on each layer of the filter screen plate 105 can be quickly filtered downward, avoiding the serious dispersion of the material during the filtering process, and realizing the rapid attraction and screening of the powder solid material entering the processing area through the arranged member, avoiding the low screening efficiency caused by the continuous dispersion of the powder solid during the screening process, so that the small particle size solid powder can be quickly and effectively layered and screened in actual operation.

[0044] Please refer to Figure 4 、 Figure 8 and Figure 9 , further, two upper sealing plates 201 are slidingly installed on both sides of the bottom of the screening main box 102, and two upper sealing plates 201 are arranged above the plugger frame 106; two lower sealing plates 202 are slidingly installed on both sides of the bottom of the screening main box 102, and two lower sealing plates 202 are arranged below the plugger frame 106; the alternating control component is arranged in the screening main box 102, and is used to drive two upper sealing plates 201 and two lower sealing plates 202 to move correspondingly.

[0045] Further, the top reverse drive mechanism 203 is arranged at the bottom of the screening main box 102, and is used to synchronously reverse drive two upper sealing plates 201; the bottom reverse drive mechanism 204 is arranged at the bottom of the screening main box 102, and is used to synchronously reverse drive two lower sealing plates 202.

[0046] In use, the screening main box 102 is used to install two plug cavities of the plug frame 106, and the upper sealing plate 201 and the lower sealing plate 202 are arranged at the upper and lower positions of the plug cavities, respectively. The opening and closing of the upper and lower openings of the plug cavities can be controlled by sliding the upper sealing plate 201 and the lower sealing plate 202, and the movement of the two plug frames 106 can complete the downward and outward guiding of the solid powder materials in the screening main box 102.

[0047] According to the installation positions of the plug frame 106, the upper sealing plate 201 and the lower sealing plate 202, they can be divided into two groups, front and back. When the front plug frame 106 moves to the right side of the screening main box 102, the rear plug frame 106 will move to the left side under the action of the driving member. During the right movement of the front plug frame 106, the plug cavity at the front side will enter the plug-in mode. At this time, the upper sealing plate 201 at the front side is opened, and the lower sealing plate 202 at the front side is closed. Then, with the continuous right movement of the front plug frame 106, the volume of the plug cavity at the front side will continuously increase.

[0048] Because the volume of the plug cavity at the bottom suddenly starts to increase, the gas at the top of the screening main box 102 will quickly flow down to the bottom, thereby driving the solid powder materials to continuously flow down, so that the floating powder materials can quickly fall down with the airflow. During the left movement of the rear plug frame 106, the upper sealing plate 201 at the top of the left plug cavity will shield the top of the corresponding plug cavity, and the lower sealing plate 202 at the bottom of the left plug cavity will open the bottom of the left plug cavity. Therefore, the left movement of the rear plug frame 106 will not have any effect on the upper part of the screening main box 102.

[0049] After the front plug frame 106 moves to the right to the limit position, the driving member will drive the front plug frame 106 to move to the left, and the rear plug frame 106 to move to the right. At this time, the powder materials after screening have fallen into the front plug cavity. Before the left movement of the front plug frame 106 starts, the upper sealing plate 201 and the lower sealing plate 202 need to be driven correspondingly, so that the upper sealing plate 201 at the front side seals the front plug cavity, the lower sealing plate 202 at the front side opens the bottom of the front plug cavity, the upper sealing plate 201 at the rear side opens the top of the rear plug cavity, and the lower sealing plate 202 at the rear side seals and closes the rear plug cavity. At this time, the front plug cavity enters the discharge mode, and the rear plug cavity enters the plug-in mode.

[0050] As the front-side sliding stopper 106 moves to the left, the material in the front-side stopper cavity can be discharged through the bottom opening of the front-side stopper cavity. The rear-side stopper cavity will then rapidly collect powdered solid materials under the corresponding movement of the rear-side sliding stopper 106. After the front-side sliding stopper 106 moves to the designated position, the movement will switch again. Before switching, the two sets of upper sealing plates 201 and lower sealing plates 202 need to be adjusted again. By repeating this process, the rapid and continuous screening of materials in the screening main box 102 and the continuous and rapid discharge of materials from the bottom can be achieved.

[0051] The top reverse drive mechanism 203 and the bottom reverse drive mechanism 204 have similar structural principles. Both the top reverse drive mechanism 203 and the bottom reverse drive mechanism 204 consist of two sets of lead screws that drive corresponding plates and a drive structure that drives the two lead screws to rotate synchronously.

[0052] The two upper sealing plates 201 are driven by two corresponding lead screws with opposite thread directions at the same horizontal level. The two lower sealing plates 202 are also driven by two corresponding lead screws with opposite thread directions at the same horizontal level. The two lead screws at the same horizontal level mesh with a gear on the outer side and a drive gear in the middle. The drive gear in the middle is driven by a motor. When the motor drives the drive gear in the middle, the lead screws on both sides rotate synchronously under the drive of the gear. When the lead screws on both sides rotate synchronously, since the threads of the lead screws on both sides are opposite, the corresponding plates on both sides can be driven to move back and forth alternately, thus realizing the corresponding drive of the two upper sealing plates 201 and the two lower sealing plates 202.

[0053] Please see Figure 1 and Figure 2 Furthermore, the extended connecting frame 301 is slidably connected to the two withdrawable plug frames 106 and fixedly installed on one side of the screening main box 102; the two drive screws 302 are respectively threadedly connected to the two withdrawable plug frames 106, and both drive screws 302 are rotatably installed on the extended connecting frame 301; the reverse synchronization mechanism 303 is disposed on the extended connecting frame 301 and is used to drive the two drive screws 302 in reverse synchronization.

[0054] In this embodiment, the extended connecting frame 301 is disposed on the side of the screening main box 102. The extended connecting frame 301 is provided with two support frames that cooperate with the pull-out plug frame 106. The two support frames are provided with the same drive screw 302. The two drive screws 302 are respectively threadedly connected to the connecting plates on the back of the two pull-out plug frames 106. The two drive screws 302 are driven by the reverse synchronization mechanism 303. The reverse synchronization mechanism 303 consists of a bevel gear transmission mechanism and a corresponding motor. The bevel gear transmission mechanism can realize the synchronous reverse transmission of the two drive screws 302, and then drive them through the motor. In this way, the two pull-out plug frames 106 can be driven in corresponding ways by the synchronous reverse rotation of the two drive screws 302.

[0056] In this embodiment, each mounting slot on the screening main box 102 is slidably provided with a mounting bracket 401, and each mounting bracket 401 is provided with a loading slot for mounting the loading frame 104, so that the user can directly place the loading frame 104 into the mounting bracket 401, and then complete the quick installation of the filter template by sliding the mounting bracket 401.

[0057] Each mounting bracket 401 has a bottom gear platform 402 on both sides of its bottom. The two gears of the adjusting gear shaft 403 at the bottom of each mounting bracket 401 mesh with the two bottom gear platforms 402 respectively. Each adjusting gear shaft 403 is driven by a corresponding adjusting motor 404, so that the user can directly drive the adjusting gear shaft 403 through the adjusting motor 404 to move the mounting bracket 401 in and out, which facilitates the user to install and remove the filter template on the mounting bracket 401.

[0058] Preferably, the screening assembly provided by the present invention further includes a striking bracket 501, a swing gear 502, a linkage gear frame 503, a front and rear drive component, and a discharge component. The front and rear drive component includes a sliding plate 601, a connecting piece 602, a drive frame 603, and a drive cylinder 604. The discharge component includes a side baffle 701, a grading guide frame 702, a side-shifting cylinder 703, and an ejector component. The ejector component includes an ejector column 704, a pusher plate 705, and a screw drive mechanism 706.

[0059] Please see Figure 4 and Figure 7 Furthermore, the striking bracket 501 is rotatably mounted on the side of the screening main box 102 near the loading frame 104; the swing gear 502 is fixedly mounted on one side of the striking bracket 501; the linkage gear 503 meshes with the swing gear 502 and is slidably mounted inside the screening main box 102; the front and rear drive components are arranged on the screening main box 102 for correspondingly driving the linkage gear 503; the discharge component is arranged on the screening main box 102 for discharging the different grades of material after screening in layers.

[0060] Furthermore, the sliding plate 601 is slidably installed on one side of the screening main box 102; one side of the overlapping member 602 is rotatably connected to the linkage tooth frame 503, and the other side of the overlapping member 602 is rotatably connected to the sliding plate 601; the drive outer frame 603 is fixedly installed on one side of the sliding plate 601; the output end of the drive cylinder 604 is connected to the drive outer frame 603, and the drive cylinder 604 is fixedly installed on one side of the screening main box 102.

[0061] In this embodiment, during use, the screening main box 102 is provided with a corresponding overlapping cross platform in the area cooperating with the mounting bracket 401. The overlapping cross platform matches the reserved central area provided by the loading frame 104. The striking bracket 501 is rotatably mounted on the overlapping cross platform. Multiple sets of striking brackets 501 are provided on each overlapping cross platform. Each striking bracket 501 has a corresponding swing gear 502 on its side. The swing gear 502 cooperates with the toothed belt provided on the linkage gear frame 503 to facilitate the operation of the linkage gear frame 503. When the moving gear 503 moves, the swing gear 502 drives the striking bracket 501 to rotate, and the rotation of the striking bracket 501 strikes the reserved area in the middle of the loading frame 104, so that the loading frame 104 can generate a certain degree of vibration during filtration, thereby accelerating the filtration of the powder solid material above. Since the entire device guides the lighter powder material by continuously moving the airflow downward, the rapid filtration of the powder material by striking can be combined with the downward airflow to prevent the powder material from dispersing and spreading.

[0062] The overlapping platform of the impact bracket 501 is adapted to the intercepting platform set in the middle of the bottom of the loading frame 104. Therefore, in actual operation, there will not be too much dust or powder material entering the installation area of ​​the overlapping platform. Moreover, the entire impact vibration mechanism will not affect the quick assembly and disassembly of the loading frame 104 and the filter screen 105.

[0063] The bottom side of the linkage toothed frame 503 is connected to the sliding plate 601, which is slidably installed inside the rear wall of the screening main box 102, via the overlapping member 602. The sliding plate 601 of the multi-layer striking mechanism is fixed to the same drive frame 603. The drive frame 603 is driven by the drive cylinder 604. When the drive cylinder 604 drives the drive frame 603 to move up and down, all the sliding plates 601 will move under the drive of the drive frame 603. Then, through the movement of the sliding plates 601, the mechanism will coordinate with the movement of the sliding plates 601. The connecting member 602 can drive the sliding plate 601. The two sides of the connecting member 602 can be rotated. The sliding plate 601 and the linkage toothed frame 503 are respectively adapted to the sliding grooves provided inside the screening main box 102. Therefore, the up and down movement of the sliding plate 601 can be converted into the left and right movement of the linkage toothed frame 503 through the connecting member 602, realizing the back and forth movement of the striking bracket 501, so as to accelerate the filtration efficiency of the material above the filter screen plate 105 by striking the loading frame 104.

[0064] Please see Figure 3 Furthermore, the side baffle 701 is slidably installed inside the screening main box 102; the grading and discharge frame 702 is fixedly installed on one side of the side baffle 701; the output end of the side displacement cylinder 703 is connected to the grading and discharge frame 702, and the side displacement cylinder 703 is fixedly installed on the screening main box 102; the ejection component is provided on the extended connecting frame 301 and is used to push out the material inside the screening main box 102.

[0065] Furthermore, the push column 704 is slidably installed on one side of the screening main box 102; the push plate 705 is fixedly connected to the push column 704 and slidably installed on the extension connecting frame 301; the screw push mechanism 706 is disposed on the extension connecting frame 301 and is used to drive the push plate 705 to move.

[0066] In this embodiment, each set of the loading frame 104, the filter screen plate 105, and the corresponding mechanism forming the filter plate are provided with a discharge port on the side for discharging materials of the specified screening layer. The side baffle 701 is provided with an inner block, each inner block corresponding to each discharge port. The side baffle 701 is driven by the side displacement cylinder 703, so that the user can directly drive the side baffle 701 by controlling the side displacement cylinder 703, and then adjust the discharge port set on the side of the screening main box by moving the side baffle 701.

[0067] Each filter layer is also equipped with a corresponding ejector post 704 for rapid material ejection. The ejector post 704 is adapted to the sliding groove on the side of the main screening box. All ejector posts 704 are connected to the push plate 705. The push plate 705 is driven by the screw push mechanism 706. The screw push mechanism 706 consists of a corresponding screw and a motor that drives the screw 302 to rotate. When the screw push mechanism 706 drives the push plate 705 to move, all ejector posts 704 can move under the drive of the push plate 705, thereby pushing the material of different levels to the discharge port of the main screening box, and finally completing the discharge of different levels of material. A grading and export rack 702 is also provided outside the discharge port of the main screening box. The grading and export rack 702 is provided with multiple levels of guide grooves inside, each guide groove corresponding to a level of discharge port, so as to realize the tiered export of multi-level material. Then, with the help of the multi-level collection mechanism, the multi-level material can be quickly collected.

[0068] Please see Figure 12 A material screening method for diluent production, employing the aforementioned material screening device for diluent production, includes the following steps:

[0069] S1: Select filter screens 105 of different sizes according to the actual screening requirements, and then install multiple sets of loading frames 104 with corresponding filter screens 105 into the screening main box 102 through loading components.

[0070] S2: After the loading frame 104 and the filter screen 105 are installed, the powder solid material to be screened is introduced through the sealing guide cylinder 103 set at the top of the screening main box 102. After the powder solid material is introduced, the bottom of the sealing guide cylinder 103 needs to be closed and sealed.

[0071] S3: After the material is introduced, it undergoes multi-level rapid screening through the multi-layer filter screen 105 set inside the screening main box 102. At this time, the two pull plugs 106 set at the bottom of the screening main box 102 will move alternately under the drive of the pull component.

[0072] S4: The opening and closing control components of the two alternating moving pull plugs 106 generate a continuous downward airflow inside the screening main box 102, so that the powder solid material on each layer of the filter screen 105 can be quickly moved downward for filtration, avoiding the serious dispersion of material during the filtration process.
