Description

Technical Field

[0001] The invention relates to the technical field of bamboo charcoal processing, in particular to a circulating grinding and crushing device for bamboo charcoal processing. Background Art

[0002] Bamboo charcoal is a kind of charcoal made from high-altitude bamboo that is more than three years old and is fired at a high temperature of nearly 1,000 degrees. Bamboo charcoal has a loose and porous structure, its molecules are fine and porous, and its texture is hard. It has strong adsorption capacity and can purify the air, eliminate odors, absorb moisture and prevent mildew, inhibit bacteria and repel insects. It can remove moisture and absorb sweat when in contact with the human body, promote blood circulation and metabolism, and relieve fatigue. After scientific refining and processing, it has been widely used in daily life. Bamboo charcoal is an important material in the production of activated carbon. Before using bamboo charcoal to make activated carbon, the bamboo charcoal needs to be crushed. At present, when crushing bamboo charcoal, existing equipment is usually used to crush the bamboo charcoal. During the crushing process of bamboo charcoal by existing equipment, as the equipment runs at a high speed, a large amount of smoke and dust will be generated, which will cause environmental pollution. It is not easy for workers to excrete it after inhaling it, which affects their health. The invention patent with the current publication number "CN112588419B" discloses a bamboo charcoal crushing device, which first crushes the bamboo charcoal through an extrusion column, and then crushes it again through a rolling column. The two processing of the bamboo charcoal, as well as the screening mechanism, realize the integration of crushing and screening, and improve the utilization efficiency of the material. However, the rolling of the bamboo charcoal by the rolling column directly applies force to the bamboo charcoal, so that the bamboo charcoal agglomerates directly pass through the leakage plate, affecting its crushing quality. When fixing the bamboo charcoal powder, it is usually necessary to mix it with other filler powders or adhesives to enhance its formability, stability or functionality. For this purpose, the bamboo charcoal needs to be mixed. The device does not have this function and requires additional equipment, thereby increasing its use cost. Therefore, we propose a circulating grinding and crushing device for bamboo charcoal processing to solve the above problems. Summary of the Invention

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example: Figure 1-12 As shown, the present invention provides a circulating grinding and crushing device for bamboo charcoal processing, comprising a grinding and crushing base 1, a bamboo charcoal feeding pipe 2 is installed on the outer side of the grinding and crushing base 1, and a discharge pipe 12 is installed in the middle of the bottom of the grinding and crushing base 1, through which the bamboo charcoal ground and crushed by the grinding and crushing base 1 can be discharged, so as to facilitate its collection, and a connecting dividing plate 5 is detachably installed on the top of the connecting dividing plate 5, and an inner concave annular collecting frame 11 is detachably installed on the top of the connecting dividing plate 5, and an annular collecting cloth bag 6 is installed on the outer side of the grinding and crushing base 1, and the interior of the inner concave annular collecting cloth bag 6 can be connected to the outside world, and the inner wall of the grinding and crushing base 1 is provided with crushing teeth, after the ground and crushed bamboo charcoal enters the inner concave annular collecting frame 11, it is screened by the annular collecting cloth bag 6, so that the bamboo charcoal can be collected in the inner concave annular collecting frame 11, and the air of the bamboo charcoal is driven to be discharged through the annular collecting cloth bag 6; A rotatable centrifugal grinding disc 14 is installed at the bottom end of the grinding and crushing base 1, and an arc-shaped grinding tooth 24 is installed on the outer side of the top of the centrifugal grinding disc 14 to grind and crush the bamboo charcoal in cooperation with the grinding teeth on the inner wall of the grinding and crushing base 1. The bamboo charcoal that falls on the centrifugal grinding disc 14 moves toward the outer periphery of the centrifugal grinding disc 14 under the action of the centrifugal force generated by the rotation of the centrifugal grinding disc 14, and generates greater kinetic energy under the action of the rotation of the centrifugal grinding disc 14, and then collides with the grinding teeth on the inner wall of the grinding and crushing base 1 to crush the bamboo charcoal, and under the action of the rotation of the arc-shaped grinding teeth 24, the grinding teeth can cooperate with the arc-shaped grinding teeth 24 to grind the bamboo charcoal between them. Grinding and crushing, a rotatable sorting component is installed at the center of the top of the centrifugal grinding disc 14, and the sorting component can rotate together with the centrifugal grinding disc 14. The bamboo charcoal that cannot pass through the sorting component can be thrown out, which effectively reduces the bamboo charcoal powder from sticking to the sorting component and affecting the subsequent sorting of the bamboo charcoal powder. The bottom of the connecting index plate 5 is installed with a conical separation cover 20 for separating the sorting component and the crushing teeth. The bamboo charcoal thrown out by the sorting component falls downward on the centrifugal grinding disc 14 under the guidance of the conical separation cover 20, and then under the action of the rotation of the centrifugal grinding disc 14, the bamboo charcoal passes through the bottom of the conical separation cover 20 to the outer periphery of the centrifugal grinding disc 14 for further grinding and crushing; There is a gap between the outer side of the centrifugal grinding disc 14 and the crushing teeth, and a sorting air inlet pipe 3 is installed at the bottom of the grinding and crushing base 1 to blow the bamboo charcoal powder upward through the gap, that is, the sorting air inlet pipe 3 sends air through the gap to blow the crushed bamboo charcoal powder upward, and the bamboo charcoal powder moves upward between the crushing teeth and the conical separation cover 20 to avoid affecting the free fall of the bamboo charcoal powder thrown out by the sorting component. An upper concave guide groove 2 is provided between the conical separation cover 20 and the bottom of the connecting index plate 5 to guide the sorting component from top to bottom. 3, that is, the bamboo charcoal powder that moves upward from between the crushing teeth and the conical separation cover 20 moves toward the sorting assembly through the upper concave guide groove 23, and then is sorted by the sorting assembly. The bamboo charcoal powder sorted by the sorting assembly enters the interior of the sorting assembly and is transported from top to bottom to the concave annular collection frame 11 for storage. That is, the bamboo charcoal powder that passes through the sorting assembly can move upward from the sorting assembly into the concave annular collection frame 11 and be sieved by the annular collection bag 6, so that the bamboo charcoal powder is stored in the concave annular collection frame 11; The discharge pipe 12 is installed at the bottom of the sorting component and passes through the center of the centrifugal grinding disc 14 to connect the interior of the sorting component with the outside world, that is, the bamboo charcoal powder in the sorting component can be discharged through the discharge pipe 12. The interior of the discharge pipe 12 is equipped with an electromagnetic valve 25, which can control the switch of the discharge pipe 12. When the discharge pipe 12 is closed, the bamboo charcoal powder entering the sorting component can enter the concave annular collection frame 11 and be stored in the concave annular collection frame 11. When the electromagnetic valve 25 is opened, the mixed bamboo charcoal powder in the sorting component can be discharged; The sorting component includes a plurality of opening and closing sorting grids 21 and a rotating spiral impeller 4 for sucking air. When the sorting grids 21 are in contact with each other, the sorting component is isolated from the inside of the grinding and crushing base 1. At this time, the electromagnetic valve 25 is in a closed state, and the concave annular collecting frame 11 is opened, and the bamboo charcoal inside it is mixed in the sorting component under the rotating stirring of the spiral impeller 4. That is, when the sorting grid 21 is opened, the rotation of the spiral impeller 4 can suck air, and the ground and crushed bamboo charcoal can be sorted under the action of the sorting grid 21, ensuring the degree of bamboo charcoal crushing, and transported to the concave annular collecting frame 11 for storage. When the sorting grid 21 is closed, the bamboo charcoal in the concave annular collecting frame 11 falls into the sorting component and can be mixed under the action of the rotating stirring of the spiral impeller 4, thereby achieving the dual effects of sorting, circulating, crushing and mixing of bamboo charcoal.

[0020] The grinding and crushing base 1 includes a fixed base 13 at the bottom, and the discharge pipe 12 is circularly mounted on the center of the fixed base 13, that is, the discharge pipe 12 can rotate relative to the fixed base 13, and the discharge pipe 12 is located on the outer side above the fixed base 13 and is cross-connected with the centrifugal grinding disc 14 to drive the centrifugal grinding disc 14 to rotate, that is, the centrifugal grinding disc 14 is connected to the discharge pipe 12, so that the centrifugal grinding disc 14 can rotate together with the discharge pipe 12 to drive the centrifugal grinding disc 14 to rotate, so that the centrifugal grinding disc 14 can rotate together with the discharge pipe 12. The disc 14 can smoothly generate a rotating centrifugal force to swing the bamboo charcoal thereon. The sorting air inlet pipe 3 is located between the centrifugal grinding disc 14 and the fixed base 13 and is in a circular shape. One end of the sorting air inlet pipe 3 passes through the grinding and crushing base 1 and is connected to the outside world. An air outlet is provided at the top of the circular ring portion of the sorting air inlet pipe 3, that is, air can be supplied vertically upward through the sorting air inlet pipe 3, and the ring-shaped sorting air inlet pipe 3 is used to relatively evenly supply air to the periphery of the centrifugal grinding disc 14, thereby ensuring the wind blowing effect everywhere.

[0021] The sorting component also includes: An opening and closing shaft 31 is vertically mounted on the sorting grid 21. The rotation of the opening and closing shaft 31 drives the sorting grid 21 to rotate about the opening and closing shaft 31, thereby switching the sorting grid 21 open and closed, thereby switching the open and closed states of the sorting assembly. The bottom mounting ring frame 27 is plugged into the top of the discharge tube 12 at multiple points, that is, the bottom mounting ring frame 27 can be disassembled relative to the discharge tube 12, and the discharge tube 12 can be driven to rotate by the bottom mounting ring frame 27. The inner side of the bottom mounting ring frame 27 is equipped with a plurality of support connecting rods 26 intersecting at a point on the center line of the bottom mounting ring frame 27. The rotation of the support connecting rods 26 can drive the bottom mounting ring frame 27 to rotate. The support connecting rods 26 are commonly connected to a transmission shaft 29, that is, on the transmission shaft 2 9 is driven by rotation, so that the supporting connecting rod 26 can rotate, thereby driving the sorting grid 21 and the centrifugal grinding disc 14 to achieve the effect of rotation. The bottom end of the opening and closing rotating shaft 31 is plugged into the top of the bottom mounting ring frame 27, that is, the rotation of the bottom mounting ring frame 27 can drive the opening and closing rotating shaft 31 to rotate together, so that the sorting grid 21 can rotate together. Then, when the sorting grid 21 sorts bamboo charcoal, the sorting grid 21 can throw out the bamboo charcoal that cannot pass through the sorting grid 21, so that it can be crushed again. The top mounting ring frame 22 is plugged into the top end of the opening and closing rotating shaft 31, and the top mounting ring frame 22 is movably mounted on the bottom of the connecting indexing plate 5. Then, by installing the connecting indexing plate 5, the top mounting ring frame 22 can be positioned, and by disassembling the connecting indexing plate 5, the top mounting ring frame 22 can be disassembled, and the sorting assembly can be disassembled, thereby facilitating its maintenance. The top end of the opening and closing rotating shaft 31 passes through the top mounting ring frame 22 and is connected to a transmission mechanism that drives the sorting grid 21 to open and close. The transmission mechanism can drive the opening and closing rotating shaft 31 to rotate, thereby achieving the effect of opening and closing the sorting grid 21. The outer transmission ring sleeve 28 is sleeved on the outer side of the transmission shaft 29, that is, the outer transmission ring sleeve 28 can rotate relative to the transmission shaft 29, and the outer transmission ring sleeve 28 and the transmission shaft 29 can rotate independently, and the spiral impeller 4 is installed on the outer side of the outer transmission ring sleeve 28. Under the action of the rotation of the outer transmission ring sleeve 28, the spiral impeller 4 can rotate smoothly. When the sorting grid 21 and the electromagnetic valve 25 are closed, the spiral impeller 4 plays a stirring role. When the sorting grid 21 is open, the spiral impeller 4 plays a suction role. The top ends of the outer transmission ring 28 and the transmission shaft 29 are connected to a gear driving mechanism, which can drive the outer transmission ring 28 and the transmission shaft 29 to rotate respectively.

The first gear 32 and the second gear 33 are respectively meshed with the third gear 34 and the fourth gear 35. The first gear 32 and the second gear 33 can be driven to rotate respectively through the third gear 34 and the fourth gear 35. The diameter of the third gear 34 is larger than the diameter of the fourth gear 35, so that a speed difference can be formed between the first gear 32 and the second gear 33, and the rotation speed of the second gear 33 is greater than that of the first gear 32, so that the rotation speed of the spiral impeller 4 is greater than the rotation speed of the sorting grid 21, thereby ensuring that the spiral impeller 4 can smoothly perform air suction. A mounting box 18 is installed on the top of the concave annular collecting frame 11 , and the first gear 32 , the second gear 33 , the third gear 34 , and the fourth gear 35 are all located in the mounting box 18 .
