Description

Technical Field

[0001] The present invention relates to the field of pulverization technology, in particular to an energy-saving pulverizer for ganoderma lucidum production. Background Art

[0002] As the core processing unit of modern powder engineering, the ultrafine grinding system works on the principle of deconstructing materials into micron-scale or even nano-scale ultrafine powders through the combined action of high-frequency mechanical impact and shearing. During the ultrafine grinding process of Ganoderma lucidum, the grading system relies on the centrifugal force field formed by the high-speed rotating grading wheel to screen the particle size of the micropowder. In theory, only particles that meet the standards are allowed to pass through the grading wheel. However, actual working conditions show that when the particle size of Ganoderma lucidum particles reaches below 300μm, they will form heterogeneous clusters under the strong interactions of electrostatics, van der Waals forces, surface energy and chemical bonds under pneumatic conveying conditions. The particles in the agglomerate are aggregated to form secondary agglomerates, the equivalent particle size of which far exceeds the threshold value designed for the grading wheel. As a result, the particles with qualified particle size in the agglomerate are returned to the crushing zone together with the blocked particles with unqualified particle size for cyclic crushing, resulting in an increase in the proportion of particles with qualified particle size in the crushing zone. This phenomenon not only increases the load of the crushing zone, reduces the efficiency of Ganoderma lucidum particle crushing, and increases the energy consumption of the crusher, but also excessive crushing will destroy the crystal structure of the active ingredients of Ganoderma lucidum, leading to irreversible degeneration of heat-sensitive functional components (such as triterpenoid compounds), and ultimately causing a decrease in the bioavailability of the product. Summary of the Invention

[0003] The present invention provides an energy-saving pulverizer for Ganoderma lucidum production, which overcomes the disadvantages of existing ultrafine pulverizers that particles may agglomerate secondary during use, resulting in reduced Ganoderma lucidum particle pulverization efficiency, increased energy consumption, and decreased product bioavailability.

[0010] Furthermore, it also includes: a support tube, fixed to a position inside the shell near the conical cover, the support tube is fixed with drainage ribs that are circumferentially equidistantly distributed, the drainage ribs are fixed to the conical cover, and the drainage ribs are inclined in a bottom-up direction along the rotation direction of the mounting disk to facilitate the airflow to drive the particles to move.

[0012] Furthermore, the upper side of the mounting plate is provided with spiral ridges equidistantly distributed in the circumferential direction, and the spiral ridges are used to guide the particles on the upper side of the mounting plate to flow toward the outside thereof.

[0022] An energy-saving crusher for Ganoderma lucidum production, see Figures 1-6 , comprising: a shell 1, the shell 1 is provided with an air inlet 101, a feed port 102 and a discharge port 103 from bottom to top, the shell 1 is equipped with a first motor 2, the output shaft of the first motor 2 is fixedly connected to a connecting shaft 3 located in the shell 1, and the connecting shaft 3 is fixedly connected to a classifying wheel 4 rotatably connected to the shell 1; a conical cover 5 is arranged in the shell 1 near the classifying wheel 4, the upper side of the conical cover 5 is fixedly connected to a guide member 6, the guide member 6 is fixedly connected to a mounting cylinder 7, the central axes of the classifying wheel 4, the conical cover 5 and the mounting cylinder 7 are all collinear, the mounting cylinder 7 is used to guide the particles, and the inner side of the mounting cylinder 7 is fixedly connected to impact bars 8 distributed equidistantly in the circumference, and the impact bars 8 is used for particles to collide; a crushing assembly is arranged in the shell 1 and is used to crush the Ganoderma lucidum; the impact bar 8 is tilted in the bottom-up direction along the rotation direction of the grading wheel 4 to provide an upward component of force for the particles; the impact bar 8 is provided with an impact surface 801, and the impact surface 801 is used for particles to collide; the impact bar 8 is provided with a drainage surface 802, and the cross-section of the impact bar 8 is triangular, and the side corresponding to the minimum angle is located on the impact surface 801, and the side corresponding to the maximum angle is located on the mounting tube 7; the impact surface 801 is provided with evenly distributed protrusions 803, and the protrusions 803 are used to guide the particles and increase the dispersion range of the particles.

[0023] The above scheme aims to solve the problem that the existing ultrafine pulverizer has the phenomenon of secondary agglomeration of particles during use, which leads to reduced efficiency of pulverization of ganoderma lucidum particles, increased energy consumption and decreased bioavailability of the product; this scheme uses the centrifugal force field formed by the rotation of the classifying wheel 4 to drive the large particles to slide along the inner side of the mounting cylinder 7 and collide with the impact bar 8, providing a secondary dispersion opportunity for the agglomerated materials in the large particles, improving the discharge efficiency and reducing the ineffective secondary pulverization process, thereby improving the pulverization efficiency of ganoderma lucidum, reducing energy consumption and reducing the damage to the heat-sensitive functional components of ganoderma lucidum; in actual use When in use, the air inlet 101 is connected to the external air supply device, so that an upward airflow is formed in the shell 1, and the airflow is used to drive the particles to flow and enter the centrifugal field of the classifying wheel 4; the feed port 102 is connected to the feeder; the discharge port 103 is connected to the external cyclone separator, and the cyclone separator is used to separate the gas and particles; the guide member 6 provides a smooth flow path for the airflow in the shell 1; the mounting cylinder 7 is a cylinder, and its inner diameter is determined according to the range of the centrifugal field formed by the rotation of the classifying wheel 4, so that the particles can contact the inner side surface of the mounting cylinder 7 under the action of the centrifugal field and move downward in a spiral along its inner side surface.

[0024] The impact bar 8, which is tilted along the rotation direction of the grading wheel 4, can provide an upward component of force for the particles when the particles collide with the impact surface 801, thereby extending the path of the particles moving in the mounting cylinder 7; the impact surface 801 is used to reduce the probability of particles accumulating near the impact bar 8, and guide the particles to continue circumferential movement after colliding with the impact bar 8; the drainage surface 802 is used to make the airflow on the impact bar 8 smoothly transition to the inner side of the mounting cylinder 7, thereby reducing the probability of turbulence in the mounting cylinder 7 and reducing the impact on the centrifugal field; the protrusion 803 is used to guide the particles formed after the agglomerated particles are impacted and crushed, thereby increasing the movement range of the particles after the agglomerated particles are crushed and reducing the probability of the particles agglomerating again.

[0025] See also Figure 2-Figure 4 The crushing assembly includes: a second motor 9, which is installed in the shell 1, and a mounting base 10 is fixedly connected to the shell 1. The mounting base 10 is rotatably connected to the transmission shaft 11, and the transmission shaft 11 and the output shaft of the second motor 9 are driven by a pulley and a belt; a mounting plate 12, which is fixed to the transmission shaft 11, and the central axis of the mounting plate 12 is collinear with the central axis of the classifying wheel 4, and the mounting plate 12 is fixed with hammers 13 equidistantly distributed in the circumferential direction; a ring gear 14, which is fixed to a position near the mounting plate 12 in the shell 1, and the ring gear 14 and the mounting plate 12 are both located between the air inlet 101 and the feed port 102.

[0026] In the above scheme, the purpose is to utilize the circumferential rotation of the hammer head 13 to crush the Ganoderma lucidum particles; there is a gap between the mounting plate 12 and the ring gear 14 and form an annular space, so that the airflow entering the shell 1 from the air inlet 101 can pass through the annular space between the mounting plate 12 and the ring gear 14 and flow upward; the pulley and belt between the transmission shaft 11 and the output shaft of the second motor 9 can be replaced by a sprocket chain, etc., which can be freely selected according to actual conditions when used.

[0027] The working principle of the above scheme is as follows: when ultrafine grinding the ganoderma lucidum particles, the first motor 2 and the second motor 9 are started, and the worker sets the speed of the first motor 2 (i.e. the strength of the centrifugal field) according to the quality of the qualified particles. The output shaft of the first motor 2 drives the classifying wheel 4 to rotate clockwise at high speed through the connecting shaft 3 (in this paper, Figure 1 The top view is a rotating perspective), a centrifugal field is generated between the classifying wheel 4 and the mounting cylinder 7; the output shaft of the second motor 9 rotates clockwise through the pulley and belt drive shaft 11, and the drive shaft 11 drives the mounting disc 12 and the hammer 13 to rotate at high speed; the external air supply device is started and air is injected into the air inlet 101. The worker sets the air supply flow rate of the air supply device according to the quality of qualified particles. The gas in the air inlet 101 enters the lower part of the shell 1. When the airflow at the lower part of the shell 1 passes through the annular space between the mounting disc 12 and the gear ring 14, it is driven by the mounting disc 12 and the hammer 13 to rotate clockwise. The airflow passes between the shell 1 and the conical cover 5 and continues to flow upward. Then the airflow flows into the centrifugal field along the shell 1 and the guide member 6. The airflow in the centrifugal field passes through the classifying wheel 4 while rotating and flows above it. Finally, the airflow is discharged into the cyclone separator through the discharge port 103.

[0028] After the first motor 2, the second motor 9 and the air supply device are started, the feeder is started and the ganoderma lucidum particles after preliminary crushing are uniformly transported to the feed port 102, and the ganoderma lucidum particles fall between the mounting plate 12 and the gear ring 14, and are driven by the mounting plate 12 and the hammer head 13 to rotate at high speed, thereby forming a circulation layer between the hammer head 13 and the gear ring 14, and the ganoderma lucidum particles are impacted and crushed by the hammer head 13 and the gear ring 14 in the circulation layer. In this process, the rising air flow continuously drives the particles (the particles here include particles with unqualified particle size, particles with qualified particle size and agglomerated particles, and the particles with unqualified particle size will be referred to as unqualified particles and the particles with qualified particle size will be referred to as qualified particles) to move upward, and the above air flow steps are repeated, and finally The airflow drives the particles into the centrifugal field. In the centrifugal field, the particles are affected by the drag force provided by the airflow toward the central axis of the classifying wheel 4, the centrifugal force during the circumferential motion of the particles, and the particles' own gravity. The drag force of the airflow on the qualified particles is greater than the centrifugal force they are subjected to, so the qualified particles directly pass through the classifying wheel 4 and are discharged through the discharge port 103. Since the mass of the unqualified particles and the agglomerated particles is greater than that of the qualified particles, the centrifugal force on the above-mentioned two particles is greater than the drag force of the airflow, so that the unqualified particles and the agglomerated particles are both affected by the centrifugal force and move outward, and finally contact the inner side surface of the mounting cylinder 7, and then spiral downward along the inner side surface of the mounting cylinder 7 under the drive of the rotating airflow in the centrifugal field and the influence of gravity.

[0029] In the process of the unqualified particles and the agglomerated particles moving spirally downward along the inner side of the mounting cylinder 7, the above two kinds of particles collide with the adjacent protrusions 803 on the impact surface 801, and the impact surface 801 exerts an upward component force on the above two kinds of particles, slowing down the downward movement speed of the particles, increasing the number of collisions between the particles and the impact surface 801, and improving the crushing efficiency of the impact bar 8 on the agglomerated particles; some of the agglomerated particles can be crushed after the collision, and under the guidance of the protrusions 803, the particles formed after the crushing move in different directions, so that the qualified particles formed after the agglomerated particles are dragged by the airflow. Under the action of gravity, the particles pass through the grading wheel 4 and are discharged. The unqualified particles and some agglomerated particles that are finally moved out of the mounting cylinder 7 collide with the inner side of the conical cover 5 under the action of centrifugal force, and slide along the inner side of the conical cover 5 to the upper side of the mounting disk 12. As the mounting disk 12 rotates, the particles on the upper side of the mounting disk 12 are affected by the centrifugal force and return to the circulating layer and are crushed for the second time. After all the Ganoderma lucidum particles are crushed and all the Ganoderma lucidum particles in the shell 1 are discharged, the first motor 2, the second motor 9, the air supply device and the feeder are stopped, and the ultrafine grinding of the Ganoderma lucidum particles is completed.

[0030] See also Figure 2-Figure 5 and Figure 7, and also includes: a support cylinder 15, which is fixed to a position near the conical cover 5 in the shell 1, and the support cylinder 15 is fixed with drainage ribs 16 that are equidistantly distributed in the circumferential direction. The drainage ribs 16 are fixed to the conical cover 5, and the drainage ribs 16 are inclined in the bottom-up direction along the rotation direction of the mounting disk 12 to facilitate the airflow to drive the particles to move; the drainage ribs 16 are provided with an arc surface and an inclined surface for guiding the particles.

[0031] The conical cover in the existing ultrafine pulverizer is installed on the inner side of the ultrafine pulverizer through a vertically arranged rib plate. When the hammer head rotates at a high speed, a spiral upward airflow is formed near the hammer head, and the vertically arranged rib plate will block the spiral upward airflow, which is not conducive to the smooth flow of the airflow in the ultrafine pulverizer, and is also not conducive to the airflow carrying the particles upward; in this scheme, an inclined drainage rib plate 16 is used to reduce the obstruction of the drainage rib plate 16 to the airflow on the one hand, so that the airflow carries the particles upward, and on the other hand, it can provide an opportunity for collision and crushing for the agglomerated particles carried by the airflow, and utilize the inclined surface and curved surface of the drainage rib plate 16 to control the movement distance of the particles, so that the particles after the agglomerated particles collide and crush are dispersed, reducing the probability of re-agglomeration and improving the discharge efficiency; the shape of the cross-section of the drainage rib plate 16 is similar to the cross-section of a wing, which provides different movement paths for the particles on both sides while reducing the resistance of the drainage rib plate 16 to the airflow; the inclination direction and angle of the drainage rib plate 16 are related to the rotation speed of the mounting disk 12 and the flow rate of the air supply device, and can be replaced and adjusted by itself during actual use.

[0032] The working principle of the above scheme is as follows: when the air flow passes through the mounting plate 12 and the gear ring 14 and drives the particles to spiral upward, the air flow drives some particles to collide with the drainage rib 16, where the agglomerated particles are crushed into two particle groups after colliding with the drainage rib 16. The two particle groups flow along the curved surface and the inclined surface of the drainage rib 16 respectively. Since the distance moved by the particle group along the curved surface of the drainage rib 16 is greater than the distance moved along the inclined surface of the drainage rib 16, the two particle groups have a distance difference while passing through the drainage rib 16. Therefore, the drainage rib 16 can disperse the two particle groups formed after the agglomerated particles collide and crush, thereby reducing the probability of the particles agglomerating again.

[0033] See also Figure 7 The upper side of the mounting plate 12 is provided with spiral ribs 17 equidistantly distributed in the circumferential direction. The spiral ribs 17 are used to guide the particles on the upper side of the mounting plate 12 to flow outward.

[0034] After the unqualified particles screened out by the grading wheel inside the existing ultrafine grinder fall onto the surface of the hammer disk (refer to the mounting disk 12 in this article), the rotation of the hammer disk is needed to drive the particles on the upper side to rotate circumferentially. Then, the particles are moved toward the crushing area by centrifugal force during the circumferential rotation. In this process, since the hammer disk first needs to drive the particles to rotate circumferentially, the speed difference between the circumferential rotation of the particles and the circumferential rotation of the hammer head on the hammer disk is small, resulting in a weakened impact force of the hammer head on the particles.

[0035] In the above scheme, the purpose is to use the spiral ridges 17 to guide the particles on the upper side of the mounting disk 12, reduce the circumferential rotation speed of the particles on the upper side of the mounting disk 12, and increase the speed difference when the particles on the upper side of the mounting disk 12 collide with the hammer head 13 again, thereby improving the efficiency of secondary crushing of the particles; the spiral ridges 17 are used to guide the particles that fall to the upper side of the mounting disk 12 to the outside when the mounting disk 12 rotates. On the one hand, the particles on the upper side of the mounting disk 12 can quickly return to the circulating layer for secondary crushing. On the other hand, it can reduce the circumferential rotation speed of the particles when entering the circulating layer, increase the rotation speed difference between the particles and the hammer head 13, and thereby enhance the collision and crushing effect of the hammer head 13 on the particles.

[0036] See also Figure 2 、 Figure 3 and Figure 7 , and also includes: a material blocking shell 18, which is fixed to the support cylinder 15 near the feed port 102, and there is a gap between the material blocking shell 18 and the conical cover 5; a guide plate 19, which is fixed to the material blocking shell 18 and inclined from top to bottom toward the central axis of the mounting plate 12, and the guide plate 19 is used to guide the particles to flow toward the adjacent hammer head 13.

[0037] In the above scheme, the guide plate 19 is used to guide the Ganoderma lucidum particles to first contact the hammer head 13 after entering the shell 1, and enter the circulating layer for crushing after being hit by the hammer head 13, thereby enhancing the crushing efficiency of the Ganoderma lucidum particles; the gap between the retaining shell 18 and the conical cover 5 is used for the air flow to carry the particles to flow upward; in actual use, the feeder delivers the Ganoderma lucidum particles into the shell 1 through the feed port 102 at a uniform speed, the Ganoderma lucidum particles move downward between the retaining shell 18 and the shell 1, and are guided by the guide plate 19 to flow to the hammer head 13, and the speed difference between the hammer head 13 and the Ganoderma lucidum particles is used to perform preliminary crushing on the Ganoderma lucidum particles, and then the Ganoderma lucidum particles enter the circulating layer for continuous crushing.

Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents.
