Description

Technical Field

[0001] This utility model belongs to the field of diatomaceous earth filler technology, and in particular relates to a powder classification device for the production of diatomaceous earth industrial fillers. Background Technology

[0002] Diatomaceous earth is a siliceous sedimentary rock with a porous structure and a porosity of 80% to 95%. It is commonly used as an industrial filler with a wide range of applications in industries such as rubber, plastics, papermaking, paints, coatings, inks, asphalt, and building materials. As a filler, diatomaceous earth significantly enhances the hardness, wear resistance, aging resistance, and corrosion resistance of products. The production of diatomaceous earth industrial fillers involves multiple steps, among which grading is a crucial step. Air classifiers, a commonly used powder grading device, utilize aerodynamic principles to precisely separate diatomaceous earth powder according to its particle size through high-speed rotating airflow and centrifugal force. This precise grading capability ensures that diatomaceous earth fillers can meet the stringent particle size distribution requirements of various application fields.

[0003] The problem with the existing technology is that if too much diatomite is added and it is in a clumpy state when the air classifier is used to classify diatomite, its fluidity will be reduced and it will be difficult to enter the classifier evenly. The clumpy diatomite may not be effectively separated, resulting in a decrease in the accuracy of the classification process. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a powder classification device for the production of diatomaceous earth industrial fillers. It has the advantage of agitating the diatomaceous earth before processing to prevent excessive agglomeration. This solves the problem that when existing air classifiers process diatomaceous earth, if too much diatomaceous earth is agglomerated, its fluidity will decrease, making it difficult to enter the classifier evenly. Agglomerated diatomaceous earth may not be effectively separated, resulting in a decrease in the accuracy of the classification process.

[0005] This utility model is implemented as follows: a powder classification device for producing diatomaceous earth industrial filler includes a classifier, a hopper, a mixing structure, a translation component, and a rotating component. The classifier has a feed inlet at its top, a support frame movably connected to its outer surface, a hopper at its top, a moving groove at its front, a rubber strip at its back, and a bracket fixedly connected to the inner wall of the hopper. A motor is mounted on the top of the bracket, and a linkage wheel is fixedly connected to the output end of the motor. A partition plate is fixedly connected to the inner wall of the hopper, and several slots are equidistantly formed on the surface of the partition plate. The mixing structure, comprising a translation component and a rotating component, is located at the front of the hopper and at the inner wall of the hopper.

[0006] As a preferred embodiment of this utility model, the translation component includes a translation bar, the back of which is fixedly connected to the front of the hopper. A translation groove is provided on the front of the translation bar, and a rotating screw is provided on the inner wall of the translation groove. By setting the translation bar, the translation bar can rotate through the translation groove in conjunction with the rotating screw, thereby driving the rotation component to operate, thus dispersing the material in the hopper before it falls into the classifier for grading processing.

[0007] In a preferred embodiment of this invention, the two ends of the rotating screw are rotatably connected to the left and right sides of the inner wall of the translation groove, respectively. The right end of the rotating screw extends and penetrates the translation groove. A driven wheel is fixedly connected to the right end of the rotating screw. The driven wheel and the linkage wheel are rotatably connected by a belt. A translation block is sleeved on the outer surface of the rotating screw. By setting the rotating screw, the motor can drive the rotation of the linkage wheel to drive the driven wheel to rotate synchronously, so that the rotating screw can rotate in the translation groove, thereby driving the movement of the translation block.

[0008] In a preferred embodiment of this invention, the outer surface of the translation block is slidably connected to the inner wall of the translation groove, the middle of the translation block is threadedly connected to the outer surface of the rotating screw, and a translation arm is fixedly connected to the front of the translation block. By setting the translation block, the translation block can be driven by the rotating screw to slide horizontally in the translation groove, so that the sliding translation block can simultaneously drive the horizontal movement of the translation arm.

[0009] In a preferred embodiment of this invention, the rotating assembly includes a rotating rod disposed on the inner wall of the hopper. The front end of the rotating rod extends out of the inner wall of the hopper through a moving groove. The front end of the rotating rod is rotatably connected to the top of the back of the translation arm via a bearing. The rotating rod is in contact with the rubber strip. A plurality of extrusion rods are fixedly connected at equal intervals on the outer surface of the rotating rod. The extrusion rods respectively match the groove. A moving gear is disposed on the front of the rotating rod. By disposing of the rotating rod, it is possible for the rotating rod to be driven by the translation arm through the moving groove, and to move horizontally synchronously within the hopper. Simultaneously, the rubber strip can be squeezed open during the movement. The movement of the rotating rod simultaneously drives the extrusion rods and the moving gear to move synchronously.

[0010] In a preferred embodiment of this invention, the moving gear is disposed on the front side of the hopper, the middle of the moving gear is fixedly connected to the outer surface of the front end of the moving rotating rod, and a drive plate is disposed at the bottom of the moving gear. By disposing of the moving gear, the moving gear can be driven by the moving rod to move horizontally on the front side of the hopper, and the moving gear can rotate in coordination with the drive plate.

[0011] In a preferred embodiment of this invention, the drive plate is disposed on the top of the translation bar, and the back of the drive plate is fixedly connected to the front of the hopper. The top of the drive plate is provided with several drive slots at equal intervals. The drive plate meshes with the moving gear through the drive slots. By setting the drive plate, the moving gear can be driven by the drive plate through the drive slots and rotate during the movement, thereby driving the synchronous rotation of the moving rotating rod, which can drive the extrusion rod to move and rotate, and insert into the slots to disperse the material clumps on the partition plate.

[0012] 1. This utility model, by setting up a classifier, hopper, mixing structure, translation component, and rotating component, achieves the effect of solving the problem that when existing air classifiers process diatomaceous earth, if too much diatomaceous earth is added and it is in a clumping state, its fluidity will be poor, making it difficult to enter the classifier evenly. The clumped diatomaceous earth may not be effectively separated, thus leading to a decrease in the accuracy of the classification process.

[0013] 2. This utility model, by setting up a hopper and a dispersing structure, allows the diatomaceous earth to be processed to be fed into the hopper. Larger clumps are intercepted by the partition plate, and then the motor drives the translation component to move, so that the moving component moves while dispersing the clumps on the partition plate, so that the fed diatomaceous earth can be in a dispersed state. Dispersing the clumps of diatomaceous earth ensures that more diatomaceous earth particles can be evenly and fully exposed to the airflow of the classifier, thereby classifying more effectively and improving the processing accuracy.

[0019] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0020] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1 to 4 As shown in the embodiment of this utility model, the powder classification device for producing diatomaceous earth industrial filler includes a classifier 1, a hopper 2, a mixing structure 3, a translation component 4, and a rotating component 5. The top of the classifier 1 is provided with a feed inlet 101, and a support frame 102 is movably connected to the outer surface of the classifier 1. The top of the classifier 1 is provided with a hopper 2, and the front of the hopper 2 is provided with a moving groove 6. The back of the moving groove 6 is provided with a rubber strip 201, and the front of the rubber strip 201 is fixedly connected to the inner wall of the hopper 2. The front of the hopper 2 is fixedly connected with a bracket 701, and the top of the bracket 701 is provided with a motor 7. The output end of the motor 7 is fixedly connected with a linkage wheel 702. The inner wall of the hopper 2 is fixedly connected with a partition plate 8, and the surface of the partition plate 8 is provided with a plurality of slots 801 at equal intervals. The front of the hopper 2 is provided with a mixing structure 3, which includes a translation component 4 and a rotating component 5. The translation component 4 is provided on the front of the hopper 2, and the rotating component 5 is provided on the inner wall of the hopper 2.

[0022] refer to Figure 3 and Figure 4The translation component 4 includes a translation bar 9, the back of which is fixedly connected to the front of the hopper 2. A translation groove 10 is provided on the front of the translation bar 9, and a rotating screw 11 is provided on the inner wall of the translation groove 10.

[0023] The above scheme is adopted: by setting the translation bar 9, the translation bar 9 can rotate through the translation groove 10 in conjunction with the rotating screw 11 to drive the rotation component 5 to operate, thereby dispersing the material in the hopper 2 and then falling into the classifier 1 for classification processing.

[0024] refer to Figure 3 and Figure 4 The two ends of the rotating screw 11 are respectively rotatably connected to the left and right sides of the inner wall of the translation groove 10. The right end of the rotating screw 11 extends and passes through the translation groove 10. The right end of the rotating screw 11 is fixedly connected to the driven wheel 12. The driven wheel 12 and the linkage wheel 702 are rotatably connected by a belt. The outer surface of the rotating screw 11 is fitted with a translation block 13.

[0025] The above scheme is adopted: by setting a rotating screw 11, the motor 7 can drive the linkage wheel 702 to rotate, thereby driving the driven wheel 12 to rotate synchronously, so that the rotating screw 11 can rotate in the translation groove 10, thereby driving the translation block 13 to move.

[0026] refer to Figure 4 The outer surface of the translation block 13 is slidably connected to the inner wall of the translation groove 10, the middle of the translation block 13 is threadedly connected to the outer surface of the rotating screw 11, and the front of the translation block 13 is fixedly connected to the translation arm 14.

[0027] The above scheme is adopted: by setting a translation block 13, the translation block 13 can be driven by the rotating screw 11 and slide horizontally in the translation groove 10. In this way, the sliding translation block 13 can simultaneously drive the translation arm 14 to move horizontally.

[0028] refer to Figure 3 and Figure 4 The rotating assembly 5 includes a rotating rod 15, which is disposed on the inner wall of the hopper 2. The front end of the rotating rod 15 extends out of the inner wall of the hopper 2 through the moving groove 6. The front end of the rotating rod 15 is rotatably connected to the top of the back of the translation arm 14 through a bearing. The rotating rod 15 is in contact with the rubber strip 201. Several extrusion rods 16 are fixedly connected at equal intervals on the outer surface of the rotating rod 15. The extrusion rods 16 respectively match the slot 801. A rotating gear 17 is provided on the front side of the rotating rod 15.

[0029] The above scheme is adopted: by setting the moving rod 15, the moving rod 15 can be driven by the translation arm 14 through the moving groove 6, and move horizontally synchronously in the hopper 2. At the same time as moving, the rubber strip 201 can be squeezed open. The movement of the moving rod 15 drives the extrusion rod 16 and the moving gear 17 to move synchronously.

[0030] refer to Figure 4 The moving gear 17 is located on the front of the hopper 2. The middle of the moving gear 17 is fixedly connected to the outer surface of the front end of the moving rod 15. A drive plate 18 is provided at the bottom of the moving gear 17.

[0031] The above scheme is adopted: by setting a moving gear 17, the moving gear 17 can be driven by the passive rotating rod 15 to move horizontally in front of the hopper 2, and the moving gear 17 can cooperate with the drive plate 18 to rotate.

[0032] refer to Figure 4 The drive plate 18 is located on the top of the translation bar 9. The back of the drive plate 18 is fixedly connected to the front of the hopper 2. Several drive grooves 19 are equidistantly provided on the top of the drive plate 18. The drive plate 18 meshes with the moving gear 17 through the drive grooves 19.

[0033] The above solution is adopted: by setting the drive plate 18, the moving gear 17 can be driven by the drive plate 18 through the drive groove 19 and rotate during the movement, thereby driving the synchronous rotation of the moving rod 15, which can drive the extrusion rod 16 to move and rotate, and insert it into the slot 801 to disperse the clumps of material on the partition plate 8.

[0034] In use, materials are fed into hopper 2. Loose, fragmented materials fall through slot 801 into inlet 101, while larger, clump-like materials remain on separator plate 8. Motor 7 drives linkage wheel 702 to rotate, which in turn drives driven wheel 12 via belt. This drives rotating screw 11 to rotate in translation groove 10. Rotating screw 11 moves translation block 13 horizontally within translation groove 10, allowing translation block 13 to simultaneously move translation arm 14 horizontally. Simultaneously, translation arm 14 moves, driving rotating rod 15 through translation groove 6 within hopper 2, and also driving extrusion rod 16 and moving gear 17. Moving gear 17, while moving horizontally, is driven by drive plate 18 via drive groove 19 to rotate. The rotating rod 15 moves within the hopper 2, simultaneously squeezing open a portion of the rubber strip 201. After the rotating rod 15 moves away, the rubber strip 201 returns to its original position to prevent material leakage. The rotating rod 15 drives the extrusion rod 16 to move horizontally while rotating. During rotation, the extrusion rod 16 extrudes the clumps of material and inserts into the slot 801 to disperse the material on the separator plate 8, allowing it to fall and enter the classifier 1 through the feed inlet 101. The classifier 1 then classifies the material. When the translation block 13 moves to the end of the moving trough 6, the motor 7 reverses, driving the rotating screw 11 to reverse. This causes the translation block 13 to move in the opposite direction, driving the rotating rod 15 to move in the opposite direction while simultaneously reversing its rotation, again dispersing the material on the separator plate 8. This process is repeated until the material classification is complete.

[0035] In summary, this powder classification device for producing diatomaceous earth industrial fillers solves the problem that when an air classifier processes diatomaceous earth, if too much diatomaceous earth is fed into it and it is in a clump state, its fluidity will decrease, making it difficult to enter the classifier evenly. The clumped diatomaceous earth may not be effectively separated, thus reducing the accuracy of the classification process.
