Description

Technical Field

[0001] The invention relates to the technical field of granulation devices, in particular to a continuous granulation device for processing Chinese patent medicines. Background Art

[0002] A rotary granulator is a mechanical device used to granulate powdered or small block materials through rotation. In industrial applications, in order to ensure the stability and efficiency of continuous production, rotary granulators are usually designed to be able to operate continuously for a long time. At present, when using a rotary granulator to prepare Chinese patent medicine granules, it is necessary to first mix the dry Chinese patent medicine powder with a certain volume of liquid to prepare a material with a certain humidity, and then place the material in the screen of the rotary granulator so that the material is squeezed by the extrusion impeller and the screen to increase the compactness of the material, and finally the compacted material passes through the mesh of the screen to form Chinese patent medicine granules.

[0003] After the material ratio is completed, the dryness and wetness of the material will directly affect the compactness of the final prepared Chinese patent medicine granules. If the material is relatively dry, the binding force between the Chinese patent medicine granules will be weakened, which will make the Chinese patent medicine granules more easily broken or scattered during subsequent storage and transportation, affecting the integrity and stability of the Chinese patent medicine granules. For relatively dry materials, additional pressure needs to be applied to the materials during the preparation process to increase the compactness of the Chinese patent medicine granules. However, during use, the existing rotary granulator only extrudes the material through the extrusion impeller and the screen, and the extrusion force applied to the material is limited. It is difficult to apply sufficient pressure to the material when the humidity of the material is low, which affects the granulation effect of the material, that is, the granulation effect of the Chinese patent medicine. Summary of the invention

[0006] More preferably, the projection of the discharge port on the horizontal plane is an isosceles trapezoid, and the diameter of the discharge port on the side close to the primary screen is smaller than the diameter on the side away from the primary screen, so as to cut off the material passing through the primary screen.

[0007] More preferably, the maximum distance between the facing sides of two adjacent discharge ports is greater than the diameters of adjacent mesh holes on the primary screen, thereby ensuring the blocking effect of the intercepting shell on the mesh holes on the primary screen.

[0008] More preferably, it also includes: A secondary screen is slidably connected to the inside of the primary screen, a third-level screen is slidably connected to the inside of the secondary screen, a fourth-level screen is slidably connected to the inside of the third-level screen, and the fourth-level screen is slidably matched with the feed pipe to change the size of the extruded Chinese patent medicine particles; A positioning bolt is fixedly connected to the outer side of the feed pipe through a connecting piece, and the secondary screen, the tertiary screen and the quaternary screen are all rotatably connected with nuts threadedly connected to the positioning bolt.

[0009] More preferably, the apertures of the meshes on the primary screen, the secondary screen, the tertiary screen and the quaternary screen are the same, and adjacent meshes on the four screens are connected to ensure smooth movement of the material in the primary screen.

[0010] More preferably, the inner sides of the secondary screen, the tertiary screen and the quaternary screen are all provided with a rubber layer to increase the sealing performance among the three.

[0011] More preferably, it also includes: A stirring component, the stirring component is used to stir and squeeze the material on the primary screen, the stirring component is arranged on the blocking plate, and the stirring component includes: A fixing plate, rotatably connected to the blocking plate; A connecting shaft is fixedly connected to the fixing plate in a through-type manner and is used to drive the fixing plate to rotate synchronously. The mounting seat is provided with a driving member for driving the connecting shaft to rotate. The fixed shafts evenly distributed in the circumferential direction are all rotatably connected to the fixed plate. The fixed shaft is fixed with an extrusion block. The extrusion block is slidably matched with the sealing plate. The extrusion block is extrusion-matched with the first-level screen, the second-level screen, the third-level screen and the fourth-level screen.

[0012] More preferably, the stirring assembly further comprises: A fastening nut, threadedly connected to the connecting shaft; A connecting plate, rotatably connected to the fastening nut; The circumferentially evenly distributed fixed shafts all penetrate the connecting plate and are slidably connected thereto, the circumferentially evenly distributed fixed shafts are all provided with guide grooves, the connecting plate is inlaid with circumferentially evenly distributed guide balls, and the guide balls on the connecting plate slide in the guide grooves on the adjacent fixed shafts.

[0013] More preferably, the height of the extrusion block is equal to the distance between the discharge pipe and the facing sides of the blocking plate, so as to reduce the moving space of the material in the primary screen.

[0015] The beneficial effect is that the present invention intercepts the material in the mesh of the first-level screen through the interception shell, thereby increasing the compactness of the material in the mesh of the first-level screen, thereby increasing the compactness of the subsequently prepared Chinese patent medicine granules, and improving the stability of the Chinese patent medicine granules during subsequent storage and transportation.

[0016] During the rotation of the intercepting shell, the intercepting shell squeezes the material extruded from the mesh of the first-level screen, causing the material to break due to the shear force, thereby preventing excess material from adhering to the first-level screen. At the same time, the extrusion pressure on the material extruded from the mesh of the first-level screen is reduced, and the degree of deformation of the material extruded from the mesh of the first-level screen is reduced, thereby ensuring the uniformity of the shape of the Chinese patent medicine particles.

[0017] By changing the relative positions of the first-level sieve, the second-level sieve, the third-level sieve and the fourth-level sieve, the compacted length of the Chinese patent medicine particles can be changed under the premise of maintaining the same compactness, so as to avoid the intercepting shell contacting the compacted part of the material after reducing the particle size of the Chinese patent medicine particles, causing the material to break in the compacted part, thereby reducing the compactness of the prepared Chinese patent medicine particles and reducing the stability of the Chinese patent medicine particles during subsequent storage and transportation.

[0018] By changing the position of the extrusion block, the extrusion block is made to fit with the inner wall of the adjacent screen, thereby ensuring the extrusion force of the extrusion block on the material, avoiding a decrease in the compactness of the prepared Chinese patent medicine granules, and reducing the stability of the Chinese patent medicine granules during subsequent storage and transportation.

DETAILED DESCRIPTION

[0021] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0022] like Figure 1-Figure 6As shown, the present invention proposes a continuous granulating equipment for processing Chinese patent medicines, which is used for preparing Chinese patent medicine powder into Chinese patent medicine granules, including: a mounting seat 1; a guide shell 2, which is fixedly connected to the upper side of the mounting seat 1; a mounting shell 3, which is embedded in the middle of the guide shell 2, and the mounting shell 3 is fixedly connected to the mounting seat 1; a primary screen 4, which is fixedly connected to the guide shell 2 through a connecting piece, and the primary screen 4 is fixedly connected to the mounting shell 3; an intercepting shell 5, which is rotatably connected to the outer side of the primary screen 4, and is used to block the mesh holes on the primary screen 4, and the intercepting shell 5 is provided with a circumferentially uniformly distributed discharge port 6, which is used to discharge the material in the primary screen 4, the intercepting shell 5 is rotatably connected to the mounting shell 3, and the guide shell 2 is provided with a driving module, and the driving module is used to drive the intercepting shell 5 to rotate; a feeding pipe 7, which is fixedly connected to the guide shell 2 through a connecting piece, and is used to guide the material downward; a blocking plate 8, which is fixedly connected to the upper side of the mounting shell 3, and the blocking plate 8 is fixedly connected to the primary screen 4, and is used to block the lower side of the primary screen 4.

[0023] In the above scheme, it is intended to solve the problems existing in the use of the existing spiral granulator. The granulation equipment of this embodiment includes a mounting seat 1, which is constructed of high-strength steel to ensure the stability and load-bearing capacity of the entire device, and provide a solid mounting platform for the guide shell 2 and the mounting shell 3. The guide shell 2 is located on the upper part of the mounting seat 1, and the two are fixedly connected by a connector, and the guide shell 2 is used to guide the prepared Chinese patent medicine particles. The primary screen 4 is provided with mesh holes that are uniformly distributed circumferentially and in a linear array, and the primary screen 4 is fixedly connected to the guide shell 2 by a circumferentially uniformly distributed connector, ensuring the stability of the primary screen 4 and the parts connected thereto, and the primary screen 4 is located on the upper side of the mounting shell 3. The drive module can be selected as a stepper motor and a gear set, wherein the gear set is respectively fixed to the output shaft of the stepper motor and the mounting shell 3, wherein the stepper motor can be installed on any connector between the primary screen 4 and the guide shell 2. The degree of the step angle of the stepper motor (6° is used as an example in the text) can be selected according to the number of discharge ports 6, wherein the specific number of discharge ports 6 should be the same as the specific number of columns of meshes of the primary screen 4. At the initial position, the circumferentially uniformly distributed discharge ports 6 and the meshes of the primary screen 4 that are uniformly distributed circumferentially and in a linear array are staggered, and the blocking plate 8 is located inside the primary screen 4. The feed pipe 7 is composed of a vertical portion and an inclined portion that are interconnected, wherein the diameter of the inclined portion of the feed pipe 7 gradually decreases from top to bottom to facilitate the entry of the material. A pressing module is provided on the lower side of the vertical portion of the feed pipe 7, wherein the pressing module is an existing device and is not shown in the figure, and the pressing module is used to squeeze the material into the interior of the primary screen 4. A stirring module is provided inside the primary screen 4, wherein the stirring module is an existing device, and the drive module can be selected as a combination of parts such as an impeller and a drive motor, and the primary screen 4 cooperates with the stirring module to extrude the material into Chinese patent medicine particles.

[0024] Furthermore, the projection of the discharge port 6 on the horizontal plane is an isosceles trapezoid, and the diameter of the discharge port 6 on the side close to the primary screen 4 is smaller than the diameter of the side away from the primary screen 4, which is used to cut off the material passing through the primary screen 4.

[0025] In the above scheme, the shape of the discharge port 6 is optimized so that the discharge port 6 can quickly cut off the compacted material when it contacts the compacted material, thereby preventing the compacted material from being deformed by hard squeezing, and reducing the amount of material adhering to the interception shell 5. The interception shell 5 is made of stainless steel to prevent the interception shell 5 from being rusted by the wet material during use.

[0026] Furthermore, the maximum distance between the facing sides of two adjacent discharge ports 6 is greater than the diameters of adjacent mesh holes on the primary screen 4 , thereby ensuring the blocking effect of the interception shell 5 on the mesh holes on the primary screen 4 .

[0027] In the above scheme, the purpose is to optimize the distance between the opposite sides of two adjacent discharge ports 6, ensure that the interception shell 5 can block all the mesh holes on the primary screen 4 at the same time, ensure the extrusion pressure on the material in the mesh holes of the primary screen 4, and thus ensure the compactness of the Chinese patent medicine particles.

[0028] The specific working principle of the above scheme is as follows: when it is necessary to use this device to prepare the prepared Chinese patent medicine powder into Chinese patent medicine granules, the staff will first mix the powder with an appropriate amount of solution to make the powder dry material into a wet material (hereinafter referred to as material), and then the staff will put the prepared material into the discharge pipe 7 in batches, and the discharge pipe 7 will guide the material to the sealing plate 8, and then the stirring module will stir the material on the sealing plate 8 and squeeze the material on the sealing plate 8 at the same time, so that the material on the sealing plate 8 is moved in the direction close to the primary screen 4 by the extrusion force until the stirring module squeezes the material into the mesh of the primary screen 4.

[0029] After the above-mentioned materials enter the mesh holes of the first-level screen 4, they are intercepted by the interception shell 5, so that the materials in the mesh holes of the first-level screen 4 cannot flow out temporarily. At the same time, under the action of the stirring device, the materials in the first-level screen 4 continuously squeeze the materials in its mesh holes, thereby increasing the compactness of the materials in the mesh holes of the first-level screen 4, thereby increasing the compactness of the subsequently prepared Chinese patent medicine granules, and improving the stability of the Chinese patent medicine granules in the subsequent storage and transportation process. Until the materials in the mesh holes of the first-level screen 4 are squeezed for a certain time, the driving module drives the interception shell 5 to rotate 6°, so that the circumferentially evenly distributed discharge ports 6 are respectively connected to the adjacent mesh holes on the first-level screen 4 (that is, the circumferentially evenly distributed mesh holes on the first-level screen 4 are released), at this time, the materials in the mesh holes of the first-level screen 4 can flow out, and after the mesh holes on the first-level screen 4 are released for a specified time, the driving module drives the interception shell 5 to rotate 6° again, so that the interception shell 5 again blocks and blocks the circumferentially evenly distributed mesh holes on the first-level screen 4.

[0030] In the process of the above-mentioned driving module driving the intercepting shell 5 to rotate again, the inclined surface of the intercepting shell 5 squeezes the material flowing out of the mesh of the first-level screen 4, causing the material to break due to the shear force, thereby avoiding excess material from adhering to the first-level screen 4. At the same time, the extrusion pressure on the squeezed material in the mesh of the first-level screen 4 is reduced, and the deformation degree of the squeezed material in the mesh of the first-level screen 4 is reduced, thereby ensuring the uniformity of the shape of the Chinese patent medicine particles.

[0031] Further, such as Figure 3-Figure 6 As shown, it also includes: a secondary screen 9, which is slidably connected to the inside of the primary screen 4, the secondary screen 9 is slidably connected to the inside of the tertiary screen 10, the tertiary screen 10 is slidably connected to the inside of the fourth-level screen 11, the fourth-level screen 11 is slidably matched with the discharge pipe 7, and is used to change the size of the extruded Chinese patent medicine particles; a positioning bolt 12, which is fixed to the outside of the discharge pipe 7 through a connecting piece, and the secondary screen 9, the tertiary screen 10 and the fourth-level screen 11 are all rotatably connected to nuts threadedly connected to the positioning bolt 12.

[0032] In the above scheme, the diameters of the four screens, namely, the primary screen 4, the secondary screen 9, the tertiary screen 10 and the quaternary screen 11, decrease step by step. The specific size of the Chinese patent medicine granules produced can be changed by changing the relative positions of the secondary screen 9, the tertiary screen 10 and the quaternary screen 11. When the secondary screen 9, the tertiary screen 10 and the quaternary screen 11 move upward to the limit position, the lower side surfaces of the three are flush with the lower side surface of the feed tube 7. The upper side surfaces of the nuts on the three screens, namely, the secondary screen 9, the tertiary screen 10 and the quaternary screen 11, are all higher than their own upper side surfaces, so that the staff can twist the nuts easily.

[0033] Furthermore, the apertures of the meshes on the primary screen 4 , the secondary screen 9 , the tertiary screen 10 and the quaternary screen 11 are the same, and adjacent meshes on the four screens are connected to ensure smooth movement of the material in the primary screen 4 .

[0034] In the above scheme, the positions of the mesh holes on the primary screen 4, the secondary screen 9, the tertiary screen 10 and the quaternary screen 11 are limited to avoid obstruction of the movement of the material in the primary screen 4 and ensure that the material is extruded smoothly.

[0035] Furthermore, the inner sides of the secondary screen 9, the tertiary screen 10 and the quaternary screen 11 are all provided with a rubber layer to increase the sealing between the three and prevent the material on the sealing plate 8 from leaking outward along the gaps between the three.

[0036] The specific working principle of the above scheme is as follows: in the process of preparing the Chinese patent medicine granules, it is assumed that the secondary screen 9, the tertiary screen 10 and the fourth screen 11 are all inside the primary screen 4, and the material is located between the feed pipe 7, the sealing plate 8 and the fourth screen 11. The material is squeezed by the mixing module and enters the meshes of the four screens. Under the premise of the same compaction, the staff can select the specific use of the secondary screen 9, the tertiary screen 10 and the fourth screen 11 according to the size of the Chinese patent medicine granules actually required, and change the length of the material being compacted (at the same time, in the process of the drive module driving the interception shell 5 to rotate, the drive module is intermittently started, and the staff can also adjust the time difference between the two starts of the drive module according to the size of the Chinese patent medicine granules actually required). The following takes the adjustment process of the fourth screen 11 as an example for description: The staff turns the nut on the left side of the fourth-level screen 11, and the nut drives the fourth-level screen 11 to move upward along the positioning bolt 12 until the lower side of the fourth-level screen 11 is flush with the lower side of the discharge pipe 7. The staff stops turning the nut on the fourth-level screen 11, and the fourth-level screen 11 moves upward to the limit position.

[0037] After the above-mentioned four-stage screen 11 moves upward to the limit position, the staff prepares the Chinese patent medicine granules according to the above operation. At this time, the material is squeezed by the stirring device and only enters the mesh holes of the three screens of the primary screen 4, the secondary screen 9 and the tertiary screen 10, that is, the length of the compacted part of the material is reduced.

[0038] After the four-stage screen 11 is separated as mentioned above, the staff synchronously adjusts the starting time difference of the driving module so that the intercepting shell 5 is cut along the junction of the compacted part and the loose part of the material during the process of cutting off the extruded material, so as to avoid that after the particle size of the prepared Chinese patent medicine granules is reduced, the intercepting shell 5 contacts the compacted part of the material, causing the compacted part of the material to be squeezed by the intercepting shell 5 and loosened again, thereby affecting the compactness of the subsequently prepared Chinese patent medicine granules.

[0039] Further, such as Figure 5 , Figure 7 and Figure 8 As shown, it also includes: a stirring component, which is used to stir and squeeze the material on the first-level screen 4, and the stirring component is arranged on the sealing plate 8; the stirring component includes: a fixed plate 14, which is rotatably connected to the sealing plate 8; a connecting shaft 15, which is fixedly connected to the fixed plate 14 in a through-type manner, and is used to drive the fixed plate 14 to rotate synchronously, and the mounting seat 1 is equipped with a driving member for driving the connecting shaft 15 to rotate; fixed shafts 16 uniformly distributed in the circumferential direction, which are all rotatably connected to the fixed plate 14 in a through-type manner, and the fixed shaft 16 is fixedly connected with an extrusion block 17, which is slidably matched with the sealing plate 8, and the extrusion block 17 is extrusion-matched with the first-level screen 4, the second-level screen 9, the third-level screen 10 and the fourth-level screen 11.

[0040] In the above scheme, the existing stirring module is replaced by the above stirring assembly, and the fixed shaft 16 and the extrusion block 17 are shown as three in the figure and text, and the specific number of the two can be changed by the staff according to the specific use requirements. The driving member can be selected as a combination of a motor and a gearbox, wherein the motor and the gearbox are both installed on the mounting seat 1, the output shaft of the motor is connected to the input end of the gearbox, and the output end of the gearbox is connected to the connecting shaft 15.

[0041] Furthermore, the stirring assembly also includes a fastening nut 19, which is threadedly connected to the connecting shaft 15; a connecting plate 18, which is rotatably connected to the fastening nut 19; the circumferentially evenly distributed fixed shafts 16 all penetrate the connecting plate 18 and are slidably connected thereto, the circumferentially evenly distributed fixed shafts 16 are all provided with guide grooves, and the connecting plate 18 is inlaid with circumferentially evenly distributed guide balls, and the guide balls on the connecting plate 18 slide in the guide grooves on the adjacent fixed shafts 16.

[0042] In the above scheme, the three fixed shafts 16 can be driven to rotate by the up and down movement of the connecting plate 18, wherein the fixed shafts 16 rotate clockwise (in the form of Figure 7 The viewing angle from top to bottom in the figure is taken as the reference viewing angle), and the distance between the end of the extrusion block 17 away from the connecting shaft 15 and the connecting shaft 15 is increased.

[0043] Furthermore, the height of the extrusion block 17 is equal to the distance between the opposite sides of the feed pipe 7 and the blocking plate 8 , so as to reduce the moving space of the material in the primary screen 4 .

[0044] In the above scheme, the purpose is to optimize the size of the extrusion block 17. During the rotation, the upper and lower sides of the extrusion block 17 are respectively close to the lower side of the discharge pipe 7 and the upper side of the sealing plate 8, thereby reducing the activity space of the material in the primary screen 4, and reducing the upward movement amplitude of the material on the sealing plate 8 when being squeezed by the extrusion block 17, so that the extrusion force on the material is affected, thereby resulting in a decrease in the compactness of the Chinese patent medicine granules.

[0045] Furthermore, a convex side surface is provided on the side of the extrusion block 17 close to the primary screen 4, a concave side surface is provided on the side of the extrusion block 17 close to the connecting shaft 15, and an inclined surface is provided on the convex side surface of the extrusion block 17. The distance between the inclined surface on the extrusion block 17 and the convex side surface of the extrusion block 17 gradually decreases from bottom to top, which is used to scrape off the material attached to the sealing plate 8 and reduce the residual amount of material on the sealing plate 8.

[0046] At the same time, the shape of the extrusion block 17 is optimized so as to clean the material on the sealing plate 8 during the rotation of the extrusion block 17 to prevent the sealing plate 8 from being adhered to the material.

[0047] The specific working principle of the above scheme is as follows: in the above process of preparing the material into Chinese patent medicine granules, the stirring module is an existing device, and the following will replace the existing stirring module with various parts in the stirring assembly.

[0048] After the above-mentioned staff puts the material into the discharge pipe 7 and the discharge pipe 7 guides the material to the sealing plate 8, the driving member drives the connecting shaft 15 to rotate, and the connecting shaft 15 drives the three extrusion blocks 17 to rotate synchronously through the fixed plate 14. The three extrusion blocks 17 squeeze the material on the sealing plate 8 during the rotation process, so that the material is moved to a position close to the fourth-level screen 11 under pressure, and the material is squeezed into the mesh holes of the four screens. At the same time, the inclined surface on the lower side of the extrusion block 17 scrapes off the material attached to the sealing plate 8 during its rotation to reduce material waste.

[0049] After changing the position of the fourth-level screen 11, the staff can change the relative positions of the three extrusion blocks 17 so that the extrusion blocks 17 are in contact with the third-level screen 10 to ensure the extrusion force of the extrusion blocks 17 on the material. The specific process is as follows: The staff rotates the fastening nut 19, so that the fastening nut 19 gradually moves upward along the external thread on the connecting shaft 15, and the fastening nut 19 drives the connecting plate 18 to move upward synchronously, and the connecting plate 18 drives the three guide balls thereon to move upward synchronously. In the process of moving upward, the guide balls squeeze the guide grooves on the adjacent fixed shafts 16 respectively, so that the fixed shaft 16 is squeezed and rotated by the adjacent guide balls, and then the adjacent extrusion blocks 17 are driven by the fixed shaft 16 to rotate synchronously, thereby reducing the distance between the extrusion blocks 17 and the primary screen 4, until the extrusion blocks 17 are fitted with the inner wall of the tertiary screen 10. The staff stops rotating the fastening nut 19, that is, the three extrusion blocks 17 are synchronously fixed in the position fitted with the inner wall of the tertiary screen 10, to ensure the extrusion force of the three extrusion blocks 17 on the material, to avoid the extrusion force of the three extrusion blocks 17 on the material being reduced when the size of the prepared Chinese patent medicine particles is changed, thereby causing the compactness of the prepared Chinese patent medicine particles to decrease, and the stability of the Chinese patent medicine particles in the subsequent storage and transportation process to decrease.

[0050] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
