Description

Technical Field

[0001] The invention relates to the technical field of crushing devices, and in particular to a cake material breaking structure. Background Art

[0002] The cake material breaking device is a device used to break up block or cake-like materials into smaller particles or powders. The common cake material breaking device adopts the principle of centrifugal impact crushing. The cake-like materials squeezed by the roller press are fed from the feed port and fall on the breaking disk with hammer-shaped ridge lining. The main shaft drives the breaking disk to rotate at high speed. The cake material is accelerated and separated from the breaking disk under the action of the hammer-shaped ridge of the lining, and is thrown out at high speed along the tangential direction and hits the impact lining to be crushed. The material rebounded from the impact liner will be impacted again by the subsequent material flying out from the scattering disk, so that it will be more fully crushed. The cake scattering device has important applications in many industries. For example, in cement production, it is used to scatter the cakes from the roller press to facilitate the subsequent grinding and grading processes, and improve the efficiency and quality of cement production; in the food processing industry, it can break up block or cake-shaped food raw materials, such as breaking up the dough pressed into cake shape, to facilitate subsequent processing and molding; in the field of mineral processing, it is used to break up the ore cake after filtration, which is conducive to the subsequent mineral processing, drying and other processes.

[0003] A Chinese patent document with authorization announcement number CN207357221U discloses a preheating and dispersing cake material breaking and classifying machine, comprising a feed bin, a preheating and crushing bin, a breaking bin, a classifying bin and a discharge bin arranged in sequence from top to bottom, wherein the preheating and crushing bin is provided with an extrusion pair of rollers and a crushing cone arranged from top to bottom, wherein the extrusion pair of rollers is horizontally connected in the preheating and crushing bin, a crushing hammer is vertically connected to the bottom center of the extrusion pair of rollers, and a heating device is placed in the crushing cone; the crushing hammer is driven by a rotating shaft and a crushing motor to rotate in the preheating and crushing bin to crush the material coming down from the extrusion pair of rollers; and at the same time, a laterally retractable compression block is also provided between the extrusion pair of rollers and the crushing hammer in the preheating and crushing bin. There are also several conical or triangular pyramidal protrusions on the outer surface of the crushing cone. The crushing cone is driven by the rotating shaft and the crushing motor to rotate in the preheating crushing bin to crush the materials coming down from the extrusion rollers. The crushing speed is faster. At the same time, there is a laterally retractable compression block between the extrusion rollers and the crushing cone. The cake material is crushed more evenly and the higher the crushing degree is, the better the dispersion effect, high efficiency, and the uniformity of the coarse powder and fine powder is.

[0004] When the existing cake breaking device is in use, since most of the cakes are thrown out horizontally, the part that contacts the impact ring is one end edge, and the cake itself is perpendicular to the impact ring. Therefore, the end of the cake that contacts the impact ring has a high degree of crushing, while the other parts have a low degree of crushing. Therefore, the crushing is uneven, and more large pieces of material are likely to appear when discharged. Summary of the invention

[0005] The present invention provides a cake material breaking structure, aiming to solve the problem in the related art that the end of the cake material in contact with the impact ring has a high degree of crushing, while the other parts have a low degree of crushing.

[0006] The cam is provided with an impact ring on the inner wall of the shell at the height of the rotating disk, and a plurality of material-discharging rods are arranged in an array in a circumferential direction on the upper surface of the rotating disk, and the material-discharging rods gradually rise from the inner end to the outer end, and a screening channel is formed between the material-discharging rods, and a baffle is fixedly installed on one side of the material-discharging rod, and a guide rod is fixedly installed on the side of the baffle away from the material-discharging rod, and the inner end to the outer end of the guide rod gradually rises, and the inclination of the guide rod is greater than that of the material-discharging rod, and the cake material is mounted on the guide rod and the material-discharging rod. As the rotating disk rotates, the cake material slides along the guide rod, and at the same time, one side of the cake material resists against the baffle, thereby gradually standing up, and a lever is fixedly installed on one side of the baffle on which the material-discharging rod is installed, and an impact part is provided on the outer end of the lever, and there is a gap between the impact part and the plane where the side of the material-discharging rod away from the lever is located. After the cake material is thrown out along the guide rod, the impact part collides with the cake material, thereby causing the cake material to rotate horizontally.

[0007] The rotating disk rotates clockwise, and the cake material falls into the middle of the rotating disk through the feeding port. Under the action of centrifugal force, the cake material moves to the edge of the rotating disk, and the broken cake material enters the gap between the material-pickup rods, that is, enters the screening channel, and the broken cake material abuts against the bottom of the baffle plate, and thus moves along the baffle plate to the edge of the rotating disk, and finally is thrown out from the rotating disk and collides with the lower half of the impact ring. One side of the large piece of cake abuts against the baffle plate, and the bottom is mounted on the two material-pickup rods, and then slides from the inner end of the material-pickup rod along the direction of the material-pickup rod under the action of centrifugal force. During the sliding process, the cake material and the guide plate The impact part contacts the rod, so that the cake material gradually stands up during the sliding process, and then separates from the material-moving rod and the guide rod. Finally, the impact part hits the rear half of the thrown cake material, so that the cake material rotates in the horizontal direction, and finally hits the impact ring. This arrangement makes it possible for most of the cake material to not be perpendicular to the impact surface when it hits the impact ring, so as to avoid the cake material itself being perpendicular to the impact surface, which causes the force to be concentrated on one end of the cake material, resulting in poor crushing effect. After the large cake material collides with the triangular block, it falls and collides with the thrown broken cake material again, thereby being crushed again. Therefore, the crushing degree is relatively high.

[0008] Preferably, the baffle is triangular, and the bottom edge is in contact with the rotating disk, and the inner bevel has a greater inclination angle than the material removing rod, so that the inner bevel of the baffle is located above the material removing rod, thereby allowing one end of the large cake material to rest against the angle formed by the material removing rod and the baffle.

[0009] Preferably, a plurality of triangular blocks are arranged in a circular array on the upper half of the inner side of the impact ring, and the cake material thrown out from the guide rod hits the triangular blocks, which adapt to the direction of the cake material's flight, so that the cake material hits one side of the triangular blocks head-on.

[0010] Preferably, one side of the triangular block is the impact surface. When the cake material hits the impact surface, the movement direction of the cake material is perpendicular to the impact surface, so that when most of the cake material hits the triangular block, the cake material itself is not perpendicular to the impact surface, avoiding the cake material itself being perpendicular to the impact surface, resulting in force concentrated on one end of the cake material, resulting in poor crushing effect.

[0011] Preferably, an inverted cone-shaped filter cartridge is provided below the impact ring, a bulk material outlet is provided at the bottom of the filter cartridge, and a discharge valve for discharging material passing through the filter cartridge is installed on the side of the shell. Material that cannot pass through the filter cartridge is discharged through the bulk material outlet, and then the bulk material is crushed by other crushing devices, and the material passing through the filter cartridge is discharged through the discharge valve.

[0012] Preferably, the filter cartridge is formed by splicing a plurality of trapezoidal filter plates, which is convenient for splicing. At the same time, when the filter holes of one of the filter plates are deformed, it can be replaced individually to avoid excessive waste.

[0013] Preferably, the projection of the material-moving rod on the rotating disk gradually tilts clockwise from the inner end to the outer end, and the rotating disk rotates clockwise, so that the baffle exerts a thrust on the cake material that tilts away from the center of the circle.

[0014] Preferably, the distance between the outer end of the guide rod and the outer end of the material-moving rod is not greater than the distance between the inner ends of two adjacent material-moving plates, so as to prevent large pieces of cake material from falling off between the guide rod and the material-moving rod.

[0015] Preferably, the maximum length of the line segment formed between two points on the cake material is set to l, the distance between the inner ends of two adjacent material-diverting plates is greater than l / 2, the spacing between the material-diverting plates is too small, and the cake material is placed on two baffles.

[0016] Preferably, the distance between the impact part and the outer end of the guide rod in the length direction of the guide rod is x, the spacing between the impact part and the plane where the side of the material removal rod away from the removal rod is located is y, the initial velocity of the cake material when it is thrown out along the guide rod is u, and the linear velocity of the impact part is v, then x / u<y / v<l / 2u+x / u, when the cake material is thrown out for a certain distance, the impact part contacts the cake material, so that the impact part can hit the second half of the cake material, thereby causing the cake material to rotate in the horizontal direction.

[0017] By adopting the above technical solution, the beneficial effects of the present invention are as follows: 1. The rotating disk is driven to rotate clockwise by the connecting shaft, and the conveyor transports the cake material to the feed port. The cake material falls into the middle of the rotating disk through the feed port. Under the action of centrifugal force, the cake material moves to the edge of the rotating disk, and the broken cake material enters the gap between the material-pickup rods, that is, enters the screening channel, and the broken cake material abuts against the bottom of the baffle, and thus moves along the baffle to the edge of the rotating disk, and finally is thrown out from the rotating disk and collides with the lower half of the impact ring. One side of the large piece of cake abuts against the baffle, and the bottom is mounted on the two material-pickup rods, and then under the centrifugal force Under the action of the material-shifting rod, the cake material slides from the inner end of the material-shifting rod along the direction of the material-shifting rod. During the sliding process, the cake material contacts the guide rod, so that the cake material gradually stands up during the sliding process, and then separates from the material-shifting rod and the guide rod. Finally, the impact part hits the rear half of the thrown cake material, so that the cake material rotates in the horizontal direction and finally hits the triangular block. This arrangement ensures that when most of the cake material hits the triangular block, the cake material itself is not perpendicular to the impact surface, thereby avoiding the cake material itself being perpendicular to the impact surface, resulting in the force being concentrated on one end of the cake material, resulting in a poor crushing effect.

[0018] 2. After the large cake material collides with the triangular block, the broken material blocks fall down, and the broken cake material in contact with the rotating disk in the screening channel is thrown out. The broken cake material collides with the broken material blocks, and then hits the lower part of the impact ring, thereby being crushed again, so the degree of crushing is relatively high.

[0026] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0027] like Figure 1-Figure 3 As shown, a cake material breaking structure is used for initial processing of cake materials. The cake material breaking structure comprises a shell body 1, a rotating disk 2, an impact ring 3 and a filter cartridge 4. A feed port is provided on the top of the shell body 1. The rotating disk 2 is rotatably installed in the middle position of the upper inner part of the shell body 1. The outer ring of the impact ring 3 is in contact with the inner wall of the shell body 1. The filter cartridge 4 is arranged below the impact ring 3, and there is a gap between the filter cartridge 4 and the inner wall of the shell body 1, so that the material passing through the filter cartridge 4 slides down along the inner wall of the shell body 1, and the impact ring 3 and the rotating disk 2 are located at the same height. The cake material is thrown into the middle of the rotating disk 2, and the rotating disk 2 rotates. The cake material is thrown out by the centrifugal force, and then hits the impact ring 3, the cake material is broken, and then the broken material falls onto the filter cartridge 4, the small particle material passes through the filter cartridge 4, and the large particle material is discharged through the discharge hole at the bottom end of the filter cartridge 4, and then is broken by the crushing equipment.

[0028] The upper half of the shell 1 is cylindrical, and the lower half is inverted conical. A motor bracket 11 is installed on the top of the shell 1, and a motor is installed on the motor bracket 11. The output shaft of the motor is connected to the rotating disk 2 through a connecting shaft 21. The connecting shaft 21 passes through the feed port, so that the rotating disk 2 is driven to rotate by the motor. A discharge pipe 12 for discharging small particle materials is installed on the outer surface of the lower half of the shell 1. A cross-shaped cross frame (not shown in the figure) is fixedly installed in the shell 1. The rotating disk 2 is rotatably installed on the cross frame to support the rotating disk 2. When the motor is started, the connecting shaft 21 rotates, thereby rotating the rotating disk 2, so that the cake material on the rotating disk 2 generates centrifugal force, so that the cake material is thrown out, so that the cake material hits the inner wall of the impact ring 3 to complete the crushing.

[0029] like Figure 3-Figure 5As shown, a plurality of material-dispensing rods 22, baffles 23 and guide rods 24 are arranged in an array along the circumferential direction on the upper surface of the rotating disk 2. In the projection on the horizontal plane, the outer ends of the material-dispensing rods 22, baffles 23 and guide rods 24 are all located at the edge of the rotating disk 2. The middle part of the rotating disk 2 is a material-dropping area. The baffle 23 is triangular and fixedly mounted on the rotating disk 2. The material-dispensing rod 22 is fixedly arranged (for example, bolted) on one side of the baffle 23. The inner end of the material-dispensing rod 22 abuts against the rotating disk 2 and transitions evenly, so that the cake material can slide from the rotating disk 2 to the material-dispensing rod 22. The guide rod 24 is fixedly arranged on the other side of the baffle 23. The projection of the material-dispensing rod 22 on the rotating disk 2 is from the inner The outer end of the guide rod 24 is gradually inclined in the clockwise direction, and a screening channel for passing broken cake materials is formed between the material removing rods 22. The remaining cake materials are supported on the material removing rods 22 and the guide rods 24, so that large pieces of cake materials move along the material removing rods 22 against the baffle plate 23, and the rotation direction of the rotating disk 2 is clockwise, so that the baffle plate 23 applies a thrust inclined away from the center of the circle to the cake materials. The distance between the outer end of the guide rod 24 and the outer end of the material removing rod 22 is not greater than the distance between the inner ends of two adjacent material removing plates, so as to prevent large pieces of cake materials from falling off from between the guide rod 24 and the material removing rod 22. A moving rod is fixedly installed on one side of the baffle plate 23 where the material removing rod 22 is installed, and an impact portion 231 is provided on the outer end of the moving rod.

[0030] Assume that the maximum length of the line segment formed between two points on the cake material is l, the distance between the impact part 231 and the outer end of the guide rod 24 in the length direction of the guide rod 24 is x, the spacing between the impact part 231 and the plane where the side of the material-moving rod 22 away from the lever is located is y, the initial velocity of the cake material when it is thrown out along the guide rod 24 is u, and the linear velocity of the impact part 231 is v. Then, the distance between the inner ends of two adjacent material-moving rods 22 is greater than l / 2. This setting is to avoid that the spacing between the material-moving rods 22 is too small, the cake material is placed on the two baffles 23, and the cake material cannot move along the material-moving plates and the guide rod 24 to complete the erection; The distance h between the outermost ends of the material-moving rod 22 and the guide rod 24 is greater than 1 / 2 and less than 1. If h is less than 1 / 2, the cake material loses contact with the material-moving rod 22 and flips to the other side of the guide rod 24, resulting in the inability to control the direction in which the cake material is thrown out. If h is greater than 1, the material may leak from between the material-moving rod 22 and the guide rod 24 into the screening channel. At the same time, x / u<y / v<l / 2u+x / u. This arrangement enables the impact part 231 to contact the cake material after the cake material is thrown out for a certain distance, so that the impact part 231 can hit the rear half of the cake material, thereby causing the cake material to rotate in the horizontal direction, so that the planar side surface of the cake material can better cater to the inner side surface of the impact ring 3.

[0031] like Figure 4-Figure 6As shown, a plurality of triangular blocks 31 are arranged in a circular array on the upper half of the inner side surface of the impact ring 3, and one side of the triangular block 31 is a contact surface 311. When the cake material hits the contact surface 311, the movement direction of the cake material is perpendicular to the contact surface 311. The cake material thrown out from the guide rod 24 hits the impact part 231 and then rotates horizontally, and finally hits the triangular block 31, so that when most of the cake material hits the triangular block 31, the cake material itself is not perpendicular to the contact surface 311, so as to avoid the cake material itself being perpendicular to the contact surface 311, resulting in the force being concentrated on one end of the cake material, resulting in a higher degree of crushing at the end directly hit, and a lower degree of crushing at other parts, resulting in a poor crushing effect.

[0032] like Figure 2 As shown, the filter cartridge 4 is composed of a plurality of trapezoidal filter plates 41, and filter holes are provided in the range of approximately two-thirds from top to bottom of the trapezoidal filter plates 41. The lowest filter hole is located at the same height as the discharge pipe 12, and every two adjacent trapezoidal filter plates 41 are connected together by bolts. A large material outlet is formed at the bottom of the filter cartridge 4 for discharging materials that cannot pass through the filter plates into a large material crusher, thereby completing finer crushing for subsequent production.

[0033] Working principle: the motor starts, and drives the rotating disk 2 to rotate clockwise through the connecting shaft 21. The conveyor transports the cake material to the feed port, and the cake material falls into the middle of the rotating disk 2 through the feed port. Under the action of centrifugal force, the cake material moves to the edge of the rotating disk 2, and the broken cake material enters the gap between the material-pickup rods 22, that is, enters the screening channel, and the broken cake material abuts against the bottom of the baffle 23, thereby moving along the baffle 23 to the edge of the rotating disk 2, and finally thrown out from the rotating disk 2, colliding with the lower half of the impact ring 3. One side of the large piece of cake abuts against the baffle 23, and the bottom is mounted on the two material-pickup rods 22, and then under the action of centrifugal force, it is moved from the inner end of the material-pickup rod 22 along the material-pickup rod 22. The cake material slides in the direction of rotation. During the sliding process, the cake material contacts the guide rod 24, so that the cake material gradually stands up during the sliding process, and then separates from the material-moving rod 22 and the guide rod 24. Finally, the impact part 231 impacts the rear half of the thrown cake material, so that the cake material rotates in the horizontal direction, and finally impacts the triangular block 31. This arrangement makes it possible for most of the cake material to not be perpendicular to the impact surface 311 when it impacts the triangular block 31, so as to avoid the cake material itself being perpendicular to the impact surface 311, resulting in the force being concentrated on one end of the cake material, resulting in poor crushing effect. Moreover, after the large cake material impacts the triangular block 31, it falls and collides with the thrown broken cake material again, thereby being crushed again. Therefore, the crushing degree is relatively high.
