Description

Technical Field

[0001] The invention relates to the field of filtering and screening, and in particular to a filtering and screening device for precursor materials. Background Art

[0002] The early production process of precursor materials can control the particle size of the material, but cannot control the particle size distribution within the powder of the material. If the particle size distribution of the material is to be controlled, screening and grading equipment must be used.

[0003] In the production process of ternary precursors, screening not only involves the control of particle size, but also includes the inspection of the purity and crystallinity of the precursor material. Through screening, powders of different particle sizes can be filtered and impurities mixed in the materials and materials that do not meet the requirements can be removed to ensure the uniformity and purity of the raw material powder. This not only helps to improve the quality of the final product, but also improves production efficiency because it can reduce the production of unqualified products and avoid waste in subsequent production processes.

[0004] Among them, the conventional precursor material screening process uses different types of vibrating screens for screening. By setting up multiple layers of screens with different mesh sizes, the powder is graded in multiple layers. This type of equipment is highly efficient, with a general screening efficiency of 80% to 95%. The range of the particle size of the screened raw materials is large, and it is suitable for the screening processing of most precursor materials. However, during processing, no matter how the equipment structure and internal processing methods are changed, they usually face the same problem, that is, the mesh of the screen is blocked by the material, resulting in reduced screening efficiency. The blocked screen can be dredged by adding vibration, impact or friction at a certain point on the screen, but the area away from the dredging force point is greatly reduced by the amplitude effect, and the blocked material cannot be effectively dredged. In addition, under such working conditions, the area affected by vibration and impact force is more susceptible to wear, causing damage to the screen and loss of function, requiring frequent replacement.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0043] The present invention specifically discloses a filtering and screening device for precursor materials, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes: a shock-absorbing seat 1 composed of two annular plates and a plurality of shock-absorbing springs connecting the two annular plates, installed at the bottom of the equipment, a plurality of cylinders 2 stacked up and down arranged according to the screening grade and particle size classification are arranged on the upper part of the shock-absorbing seat 1, support plates are arranged on the left and right sides of the upper part of the cylinder 2, and guide sleeves are symmetrically arranged on the top of the support plates front and back; connecting guide pillars 3 are symmetrically installed on one side of the bottom of the support plates on the left and right sides of the cylinder 2, and are concentric with the guide sleeves on the support plates of the next layer, and one end of the lower part of the connecting guide pillars 3 extends into the guide sleeves on the top of the support plates at the corresponding position of the next layer, and the cylinders 2 are spliced ​​by connecting guide pillars 3 and guide sleeves, as shown Fig.13As shown, the inner wall diameters of the spliced ​​cylinders 2 are consistent, and except for the screening components, there are no other components inside that interfere with the feeding and screening of the materials in the cylinders 2. There is a height between the bottom cylinder 2 and the ground, which can be used to install a mechanical vibration or ultrasonic vibration device to provide continuous vibration force for the equipment screening. At the same time, the vibration force transmitted outward by the screening equipment is effectively buffered and weakened through the shock-absorbing seat 1. The bottom cylinder 2 is provided with a receiving plate 32 for receiving the final graded screening material. The receiving plate 32 is provided with a conical protrusion in the middle, and a line is formed between the surrounding of the conical protrusion and the inner wall of the cylinder 2. The annular drop trough is provided, and a discharge pipe 31 for discharging is provided at the tangent line of the lower part of all cylinders 2. The upper and lower positions of the discharge pipes 31 on all cylinders 2 are inconsistent. The purpose of such a setting is to reduce the difficulty of laying the material transfer pipeline when the discharge pipe 31 is connected to the external processing equipment. A cylinder cover 4 is provided on the top of the uppermost cylinder 2, and a feed port is opened on the upper part of the cylinder cover 4. A flange mounting seat for connecting a flexible pipeline is provided at the upper opening of the feed port on the cylinder cover 4. Usually, in order to prevent the vibrating screening equipment from transmitting the vibration force to the feeding equipment, the feeding equipment and the screening equipment are connected through a soft connection;

[0044] like Figure 3-8 As shown, the upper part of the cylinder 2 is provided with a boss, and except for the boss of the topmost layer of the cylinder 2, an even number of sliding blocks 5 (not less than 6) are evenly spaced and slidably provided. One end of the sliding block 5 extends into the internal space of the cylinder 2, and the width of both sides and the top height of the end are slightly smaller than the rest of the part. A card slot with an opening upward is provided thereon, and a card block 51 is embedded in the card slot of the sliding block 5. The card block 51 is snapped on the sliding block 5 to leave a gap in the wide area of ​​the sliding block 5. A filter support frame 52 is provided between the card blocks 51. The filter support frame 52 is spliced ​​by a plurality of strip-shaped and ring-shaped alloy spring pieces. When not subjected to external force, the filter support frame 52 is intact. The body is in the shape of an upwardly thrown arc surface. Different filter screens with different mesh numbers will be laid on the upward side of different filter screen supports 52, and the mesh numbers of the filter screens layered from top to bottom should increase. The filter screen should be made of an alloy material with excellent toughness and durability. Its diameter is consistent with the inner diameter of the cylinder 2, and the connection between the filter screen support 52 and the block 51 is hinged. There is a movable clearance at the hinge point of the two. When the block 51 moves with the sliding block, the connection between the filter screen support 52 and the block 51 is slightly changed in direction and position by force, so as to avoid the rigid connection force point being pulled and broken by external force when the filter screen support 52 is deformed. A raised round block is provided on the top of the outward side of the sliding block 5;

[0045] like Figure 3 , Figure 4 , Figure 6 and Fig.10As shown, it also includes a clamping mechanism 8 for covering the joint of the cylinders. The clamping mechanism 8 includes: a plurality of arc-shaped clamping strips 81 slidably arranged at the lower part of the cylinder 2 except the bottom layer, the lower part of the arc-shaped clamping strips 81 will be in contact with the convex hub on the next layer of cylinder 2, there are multiple arc-shaped clamping strips 81, which are surrounded by a ring at the lower part of the cylinder 2, and the joints of the arc-shaped clamping strips 81 are stepped. When the arc-shaped clamping strips 81 are stretched outward, the joints are still in a state of contact with each other. The purpose of this arrangement is to avoid the arc-shaped clamping strips 81 from having gaps that communicate with the outside of the device when the arc-shaped clamping strips 81 are stretched out. , which may lead to material leakage or intrusion of external substances. The inner wall of the ring formed by the arc-shaped clamping strip 81 wraps the outer edge of the filter support frame 52 of the same cylinder 2. The inner diameter of the ring formed by the arc-shaped clamping strip 81 is consistent with the inner diameter of the cylinder 2; the arc-shaped clamping strip 81 is provided with a spring 2 82, and the number is two. The other end of the spring 2 is connected to the cylinder 2. The segmented arc-shaped clamping strip 81 can connect the joints of the spliced ​​cylinders 2, and the connection is relatively tight. During filtering and screening, the material will not leak out through the gap at the joint of the cylinder 2, and the possibility of foreign substances entering the screening station can also be reduced.

[0046] like Figure 2-7 As shown, it also includes a driving mechanism 7 that provides driving force for the force-applying mechanism 6, and the driving mechanism 7 includes: a driving member 71 installed at the rear of the lowest cylinder 2, the driving member 71 is composed of a mounting frame and a driving cylinder, and a plurality of evenly arranged straight teeth are axially arranged on the rear side of the movable rod of the driving cylinder, and a transmission group 72 is provided on the mounting frame of the driving member 71, and the transmission group 72 is composed of a rotating shaft vertically and rotatably mounted on the mounting frame and a gear meshing with the straight teeth on the movable rod of the driving cylinder, which changes the linear motion into rotational motion, and drives the rotating shaft of the transmission group 72 to rotate through the driving member 71; the rear of the cylinder 2 on which the filter support frame 52 is installed is vertically provided with a shaft gear 73, and the belt The shaft body of the shaft gear 73 is on the same line as the rotating shaft of the transmission group 72. The lower part of the shaft body of the belt shaft gear 73 is set as a spline shaft, and its upper part is a spline shaft sleeve corresponding to the shape of the lower spline shaft part. Multiple belt shaft gears 73 are connected to each other up and down, and the upper part of the rotating shaft on the transmission group 72 is set as a sleeve with the same shape as the upper part of the shaft body of the belt shaft gear 73. That is to say, the lower end of the belt shaft gear 73 close to the transmission group 72 can be connected to the upper end of the transmission group 72, and the driving force provided by the driving member 71 is transmitted to the belt shaft gear 73, thereby driving multiple connected belt shaft gears 73 to rotate synchronously, and these connected belt shaft gears 73 can be flexibly disassembled along with the stacked cylinders 2, and disassembly is convenient;

[0047] like Figure 4 Figure 5 , Figure 6 , Figure 7 and Fig.10As shown, it also includes: in addition to the circular guide groove 610 opened on the upper part of the topmost layer of the cylinder 2, a rotating ring 61 is rotatably and slidably arranged in the circular guide groove 610, and an arc-shaped rack 74 is arranged at a section of the rotating ring near the belt shaft gear 73. The rack 74 will mesh with the belt shaft gear 73 at the same height, so as to transmit the rotational driving force transmitted by the transmission group 72 to the rotating ring 61. When the movable rod of the driving member 71 is extended, it will drive the transmission group 72 to rotate counterclockwise. Therefore, when the belt shaft gear 73 rotates, the rack 74 meshing therewith will drive the rotating ring 61 to rotate clockwise. The rotating ring 61 is provided with convex parts at its inner circle that are the same in number as the sliding block 5. These convex parts The position corresponds to the sliding block 5 one by one and contacts with the sliding block 5, and the sliding block 5 installed with the filter support frame 52 is stabilized and limited by the convex part when the screening work is carried out to prevent it from being displaced by force, which causes the filter support frame 52 to deflect. The convex part on the rotating ring 61 and the other parts of the rotating ring 61 form stepped gaps. These gaps open downward, and the height of one side of the upper side of the gap is consistent with the height of the top of the sliding block 5; the rotating ring 61 is provided with fixed seats 62 with the same number as the sliding block 5 at intervals, and these fixed seats 62 are respectively arranged at positions close to a single sliding block 5; the upper inward end of the fixed seat 62 is rotatably provided with an extrusion block 63, see Fig.11 A spring 64 is wound around the outer side of the upper part of the extrusion block 63, and the top of the spring 64 is connected to the limited missing block 65. A fan-shaped block is provided on the upper part of the extrusion block 63, and a semi-annular protrusion is provided on the upper part of the limited missing block 65. Under the action of the spring 64, one side of the fan-shaped block on the upper part of the extrusion block 63 contacts the semi-annular protrusion of the limited missing block 65, and the semi-annular protrusion will limit the rotation direction of the extrusion block 63, so that it does not rotate in the clockwise direction. An abnormal convex portion is provided at the lower part of the extrusion block 63: the convex portion makes the extrusion block 63 form a shape of transition from a plane to an inclined surface at the end face of the rotating ring 61, and forms a notch at the end of the inclined surface of the extrusion block 63, and an arc-shaped guiding surface is provided at the junction of the notch and the end of the inclined surface, and the arc-shaped guiding surface extends from the notch to the end of the extrusion block 63 away from the fixed seat 62;

[0048] Among them, several cylinders 2 are stacked and spliced ​​up and down by connecting guide pillars 3. There should be a large friction between the connecting guide pillars 3 and the guide sleeves on the cylinders, and the two are tightly connected. When stacking cylinders 2, the shaft gear 73 at the rear of the cylinder 2 is connected up and down, and the cylinder cover 4 is fixedly installed on the top of the cylinder 2 in the uppermost layer, and a vibration device for providing vibration force is installed in the shock-absorbing seat 1. A soft connection is installed on the mounting seat at the upper feed port of the cylinder cover 4. The external feeding equipment is connected through the soft connection. The feeding equipment will put the material into the cylinder cover 4 and the uppermost layer of cylinder 2 through the feed port, and it will fall on the central area of ​​the uppermost filter screen in the cylinder 2. The continuous and regular vibration of the equipment makes the material constantly shake and throw up on the filter screen. The material with a smaller particle size than the mesh of the filter will pass through the mesh and fall onto the next screen for screening, while the material blocked on the filter will gradually move toward the edge of the upwardly arched filter under the action of vibration, and when it moves to the discharge port of the discharge pipe 31, it will be discharged to the outside of the equipment. When the mesh holes on the screen are blocked, the material cannot pass through the mesh holes smoothly. At this time, the driving member 71 drives the shaft gear 73 to rotate counterclockwise, and then drives the rotating ring 61 to rotate clockwise through the arc-shaped rack 74. When the rotating ring 61 rotates clockwise, the extrusion block 63 will move with the rotation of the rotating ring 61. In this process, the convex portion of the rotating ring 61 gradually breaks away from contact with the sliding block 5, and the abnormal convex portion of the extrusion block 63 moves toward the rotating ring The first side of 61 will contact the round block protrusion of the sliding block 5. Under the blocking effect of the limiting missing block 65, the squeezing block 63 cannot rotate clockwise. Under the squeezing of the inclined surface of the abnormally shaped protrusion, all the sliding blocks 5 are squeezed and slid outward at the same time. The outward end of the sliding block 5 will slide into the notch on the rotating ring 61. The squeezing block 63 applies a uniform pulling force to the filter support frame 52 as a whole to the sliding blocks 5 evenly distributed at intervals. When the force-applying mechanism 6 pulls the sliding blocks 5 outward synchronously, the filter support frame 52 will be deformed into a flattened state. Under the stress of the spring sheet, the filter support frame 52 is in a force storage state at this time. When the rotating ring 61 continues to rotate, the notch at the bottom of the squeezing block 63 causes the round block protrusion of the sliding block 5 to be forced away. When the pulling force of the block 5 sliding outward disappears, the arch of the filter support frame 52 will quickly recover, pulling the sliding block 5 to slide inward and reset. When the elastic potential energy of the extrusion block 63 is released, if there is material stuck in the installed filter, the strong rebound force will cause the stuck material to be thrown upward instantly. Under the action of inertia, the material is thrown out and separated from the screen. The clamping force applied to the filter support frame 52 by the spring 82 is used to squeeze and store force, and the kinetic energy of the filter support frame 52 when it is flattened and reset is further increased, thereby improving the dredging effect. Under this action, the stress generated by the filter support frame 52 as a whole drives the filter as a whole to exert force, avoiding the occurrence of local force, and effectively solving the problem of the filter being stuck by materials and damaged by external forces.When the dredging is completed, the driving cylinder of the control driving member 71 retracts the movable rod, driving the transmission group 72 and the shaft gear 73 to rotate clockwise, thereby driving the arc rack 74 to push the rotating ring 61 to rotate counterclockwise. During the rotation and reset process, the abnormal protrusion of the extrusion block 63 will contact the circular protrusion of the sliding block 5, and the abnormal protrusion squeezes the circular protrusion. At this time, the deformation stress of the spring 1 64 is less than the deformation stress of the spring sheet of the filter support frame 52, and the limit missing block 65 does not limit the extrusion block 63 from rotating counterclockwise. Therefore, when the extrusion block 63 is subjected to the extrusion force, it can rotate counterclockwise; during the rotation and displacement process of the rotating ring 61, the circular block protrusion of the sliding block 5 slides in contact with the arc guide surface of the abnormal protrusion of the extrusion block 63, but it does not affect the process of the extrusion block 63 rotating with the rotating ring 61. When the extrusion block 63 is out of contact with the sliding block 5, under the action of the spring 1 64, the extrusion block 63 rotates and resets; the above-mentioned dredging steps and reset steps are completed in a relatively short time. ;

[0049] like Figure 1-3 As shown, it also includes: a lifting cylinder 10 installed on the support plates on both sides of the cylinder 2. The number of lifting cylinders 10 on one side of the equipment is the number of cylinders 2 minus one. The movable rod of the lifting cylinder 10 is connected to the support plate of the upper layer of cylinder 2. When the filter needs to be replaced, the cylinder 2 installed with the filter and stacked is quickly layered by the provided lifting cylinder 10. There is no need to lift the cylinder 2 manually to disassemble it, so the filter replacement part of the equipment can be exposed. There is no other component on the front side of the cylinder 2 to block the filter installation work, so replacement and maintenance are convenient, and with the snap-on installation method, the filter can be quickly maintained or replaced, thereby improving maintenance efficiency and reducing the impact of long-term shutdown due to filter maintenance on processing.

[0050] like Figure 8-9As shown, it further includes: a cushion block 111 slidably arranged in the sliding block. When the cushion block 111 is completely slid into the sliding block 5, the top of the cushion block 111 is flush with the top surface of the sliding block 5. There is an extended portion on one side of the cushion block 111 facing the filter screen support 52. The bottom of this extended portion is provided with an arc surface. The clamping block 51 is arranged in a "C" shape with an upward opening. When the clamping block 51 is inserted into the clamping groove, the height of the area where it is inserted into the sliding block 5 is the same as the height of the top of the sliding block 5 at the end where the clamping groove is opened. A anti - detachment shielding plate 112 is slidably arranged at one end of the sliding block 5 facing the opening of the clamping groove through a telescopic elastic piece 113. The bottom surface of the anti - detachment shielding plate 112 will slide - contact with the clamping block 51 inserted into the clamping groove. The anti - detachment shielding plate 112 is provided with an inclined surface on the side facing the cushion block 111. When not under external force, the telescopic elastic piece 113 will pull the anti - detachment shielding plate 112 to slide towards the extended portion side of the cushion block 111, and squeeze the cushion block 111 to move upward through the inclined surface of the anti - detachment shielding plate 112. When the cylinders 2 are stacked, the top of the cushion block 111 will contact the arc - shaped clamping strip 81 installed on the upper - layer cylinder 2 and be subjected to a downward pressing force from the arc - shaped clamping strip 81. In this state, the cushion block 111 will slide downward, and synchronously its extended portion will squeeze the inclined surface of the anti - detachment shielding plate 112, moving the anti - detachment shielding plate 112 towards the clamping block 51 side. The telescopic elastic piece 113 is stretched by the force, and covers the area where the clamping block 51 is inserted into the sliding block 5. By using the anti - detachment shielding plate 112 to limit the upward side of the clamping block 51, it is avoided that the clamping block 51 detaches from the sliding block 5 when subjected to continuous vibration force.

[0051] As Figure 1 , Figure 2 , Figure 3 and Fig.12As shown, it also includes a dispersing mechanism 9 for breaking up the fed material, and the dispersing mechanism 9 includes: a funnel 91 fixedly mounted on the cylinder cover 4 by a bracket, the lower part of which is conical, the upper opening of the funnel 91 is just opposite to the feed port of the cylinder cover 4, and the inner diameter of the funnel 91 is slightly larger than the diameter of the feed port, the lowermost discharge port of the funnel 91 is close to the arc top of the uppermost filter screen support frame 52, and an inverted cone 92 is fixedly arranged at the concentric position of the upper inner part of the funnel 91, and the upper part of the funnel 91 is upward from the feed port. The material introduced through the feeding device will first contact the inverted cone 92, and the material will be initially dispersed by the inverted cone 92. A heating block 93 is arranged concentrically at the lower part of the funnel 91. The heating block 93 is in an inverted cone shape as a whole. There is a ring gap for passing the material between the lower outer edge and the inner wall of the funnel 91. A number of smooth protrusions 95 are evenly arranged on the upper surface of the heating block 93 to prevent the material from sticking. The material sliding off the surface of the inverted cone 92 will be scattered on the feeding tube. The heat provided by the heating block 93 dries the material falling into the funnel 91 area to a certain extent. A dispersing piece 94 is fixedly installed in the inverted cone 92. The dispersing piece 94 is composed of a motor and a dispersing frame. The dispersing frame is in rotational contact with the upper surface of the heating block 93. The material accumulated in the funnel 91 is stirred and dispersed by the dispersing frame. While the material is heated and stirred, an extrusion force is applied to push the material out of the annular gap, and the material is concentrated and leaked to the central arc top of the topmost filter screen through the funnel 91 for screening. The dispersing mechanism 9 is set to mechanically disperse the material during feeding, so as to avoid the material agglomerated on the screen requiring more time for filtering and screening, thereby improving the filtration efficiency. In conjunction with the heating block 93 in contact with the material, the moist material is dried to a certain extent, and the situation in which the material with too high moisture content adheres to the filter screen is reduced.

[0052] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, it also includes: a mask 12 arranged around the outer periphery of the force-applying mechanism 6, the mask 12 surrounds the joint between the force-applying mechanism 6 and the cylinder 2, and the mask 12 is provided with openings allowing the shaft gear 73 to contact the rack 74. The mask 12 is used to shield the exposed working parts on the equipment to prevent external factors from interfering with the operation of the equipment parts, thereby providing effective protection.
