Description

Technical Field

[0001] This invention relates to the technical field of pulverizing equipment, and in particular to a pulverizer for extracting heparin from the small intestine. Background Technology

[0002] Heparin is an important anticoagulant drug widely used in the prevention and treatment of thrombosis, cardiac surgery, hemodialysis and other medical fields. It is mainly extracted from the small intestinal mucosa of pigs or the lungs of cattle. With the increasing global demand for heparin, improving its extraction efficiency and purity has become one of the key research focuses in the industry. In addition, ensuring the safety and environmental friendliness of the extraction process is also an issue that cannot be ignored.

[0003] Traditional heparin extraction methods mainly include physical, chemical, and enzymatic methods. While these methods can meet production needs to a certain extent, they also have problems such as low raw material utilization, serious environmental pollution, and high costs. To overcome these problems, modern technology is constantly exploring new extraction methods, such as ultrasonic-assisted extraction and microwave-assisted extraction. Using a pulverizer as a pretreatment tool can significantly improve the crushing effect of raw materials, increase the release rate of effective components, and thus improve the efficiency of subsequent extraction steps.

[0004] Commonly used grinders primarily use rotating blades inside to directly grind the small intestine. However, this grinding method only utilizes a cutting mechanism to grind the small intestine, thus failing to effectively grind the small intestinal cells and resulting in a low amount of heparin release. Therefore, its effect on improving heparin extraction is limited. Summary of the Invention

The spiral plate is fixed on the outer wall of the rotating drum. The lower side of the outer wall of the material box is densely covered with screen holes. A receiving hopper is sealed on the outside of the screen holes. The receiving hopper is used to collect the crushed raw material. The raw materials are introduced into the rotating drum through the opening at the top of the material box.

[0006] Furthermore, both the blades on the shearing zone and the blades on the cone are inclined, and the two ends of the blades on the shearing zone cooperate with the head end of one blade and the tail end of the other blade in two adjacent blades on the cone to form a shearing effect.

[0007] Furthermore, the rotating drum and the cone move at different speeds in the same direction, and a power unit is provided at the bottom of the material box to provide rotational power for the rotating drum and the cone.

[0008] Furthermore, a water storage chamber is provided inside the rotating drum. The shape of the water storage chamber is consistent with the shape of the rotating drum. A drain hole is provided on the inner side wall of the water storage chamber, which communicates with the middle of the rotating drum. The drain hole is used to drain water to the middle of the rotating drum.

[0009] Furthermore, an annular groove is provided at the bottom of the rotating drum, and a ring body is vertically slidably arranged in the annular groove. The shearing zone and the crushing zone are both located at the bottom of the ring body. Multiple sliding rods are vertically arranged at the top of the ring body. The top of the sliding rods is slidably inserted into the water storage chamber, and the sliding rods are connected to the rotating drum by spring pieces. The top of the annular groove is provided with multiple water inlets, which are connected to the water storage chamber. The material box is provided with a water guiding structure for supplying water to the water storage chamber.

[0010] Furthermore, the water guiding structure includes an annular groove plate rotatably installed on the top of the inner wall of the material box, the space between the annular groove plate and the material box is sealed, the annular groove plate is connected to the water storage chamber through multiple water supply pipes, and the top of the material box is provided with a water inlet pipe connected to the annular groove plate.

[0011] Furthermore, the top of the rotating drum is provided with an air hole, the output end of the air hole is inclined downward towards the axis of the rotating drum, and the input end of the air hole extends downward into the water storage chamber. A float plate is vertically slidably arranged in the water storage chamber, and the float plate is used to block the input end of the air hole.

[0012] Furthermore, the power unit includes a crossbeam fixed in the middle of the rotating drum, a rotating column at the bottom of the crossbeam, a rotating sleeve at the bottom of the cone, the bottom of the rotating sleeve extending to the bottom of the material box, the rotating sleeve being rotatably connected to the material box, the bottom of the rotating column passing through the cone and the rotating sleeve, and both the cone and the rotating sleeve being rotatably connected to the rotating column.

[0013] The beneficial effects of this invention are as follows: This pulverizer achieves multi-stage pulverization of raw materials through the design of shearing and grinding zones, effectively improving the fineness of the pulverized materials and increasing the release rate of active ingredients. By utilizing the lifting and return of incompletely pulverized materials, the raw materials can form a circulating flow state within the feed hopper, allowing for repeated and multiple pulverization processes until the raw materials meet the requirements and pass through the sieve. This continuous circulation design not only improves pulverization efficiency but also reduces raw material waste. Through multi-stage pulverization, especially the tearing and grinding processes, the cell walls of the small intestine can be more effectively broken down, making it easier for active ingredients such as heparin to be released, which helps to improve the heparin extraction rate in subsequent extraction steps. Raw materials are continuously introduced through the top opening of the feed hopper, and the pulverized raw materials are discharged through the sieve and collected in the receiving hopper, realizing continuous production and improving production efficiency.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0020] like Figures 1 to 5 As shown, a pulverizer for extracting heparin from the small intestine according to the present invention includes a feed hopper 1, a rotating drum 2 and a cone 3 located inside the feed hopper 1. The rotating drum 2 and the cone 3 are arranged vertically. The outer wall of the rotating drum 2 and the inner wall of the feed hopper 1 form a lifting channel. The top of the rotating drum 2 is set as a concave cone surface, and the top of the rotating drum 2 and the top of the inner wall of the feed hopper 1 form a return channel. The area at the bottom of the rotating drum 2 near the axis of the rotating drum 2 is set as a shearing zone 4. The distance between the shearing zone 4 and the upper surface of the cone 3 gradually decreases in the direction away from the axis of the rotating drum 2. The area at the bottom of the rotating drum 2 away from the axis of the rotating drum 2 is set as a crushing zone 5. The distance between the crushing zone 5 and the upper surface of the cone 3 gradually decreases in the direction away from the axis of the rotating drum 2. The shearing zone 4 and its corresponding upper surface area of ​​the cone 3 are each provided with multiple blades 6. The crushing zone 5 and its corresponding upper surface area of ​​the cone 3 are each densely covered with protrusions 7. The lifting channel is equipped with a spiral plate 8 for pushing and lifting the raw material upward. The spiral plate 8 is fixed on the outer wall of the rotating drum 2. The lower side of the outer wall of the material box 1 is densely covered with screen holes 9. The outer side of the screen holes 9 is encapsulated with a receiving hopper 10, which is used to collect the crushed raw material. The raw materials are introduced into the rotating drum 2 through the top opening of the material box 1.

[0021] In detail, the rotating drum 2 can rotate relative to the cone 3 inside the material box 1, so that the blade 6, protrusion 7 and spiral plate 8 on the rotating drum 2 can all move in a circular motion. The receiving hopper 10 covers the screen holes 9 on the outer wall of the material box 1. When the crushed raw material is discharged through the screen holes 9, the receiving hopper 10 will collect the raw material and discharge it naturally through the opening at the bottom of the receiving hopper 10. The space between the shearing zone 4 and the cone 3 is larger than the space between the crushing zone 5 and the cone 3.

[0022] In operation, raw materials are introduced into the middle of the rotating drum 2 through the top opening of the feed hopper 1 and fall naturally onto the cone 3. The raw materials slide obliquely along the conical surface of the cone 3 into the gap between the rotating drum 2 and the cone 3. The raw materials first enter the shearing zone 4 between the cone 3. The rotating blades 6 on the rotating drum 2 cooperate with the blades 6 on the cone 3 to continuously shear the raw materials. After shearing, the raw materials enter the crushing zone 5 between the cone 3. The moving protrusions 7 further tear and crush the raw materials. With the gradual reduction of the distance between the crushing zone 5 and the cone 3, the crushing effect of the raw materials can be achieved. In this way, the raw materials can undergo multiple crushing processes between the rotating drum 2 and the cone 3. The crushed raw materials are then discharged to the screen. Near hole 9, qualified raw materials will be discharged into receiving hopper 10 through screen hole 9, while unqualified raw materials will be intercepted between rotating drum 2 and material box 1. Using rotating spiral plate 8, the incompletely crushed raw materials can be lifted upward into the return channel and the conical surface at the top of rotating drum 2 can be used to make the raw materials re-enter rotating drum 2. The raw materials in rotating drum 2 fall again and enter between rotating drum 2 and cone 3. This realizes the automatic return and continuous crushing effect of unqualified raw materials. During this process, new raw materials can be continuously introduced into material box 1 through the top opening of material box 1 for crushing, while the thoroughly crushed raw materials will be continuously discharged through screen hole 9. This realizes the continuous crushing of raw materials.

[0023] This pulverizer, through the design of a shearing zone 4 and a grinding zone 5, achieves multi-stage pulverization of raw materials, effectively improving the fineness of the pulverized materials and increasing the release rate of active ingredients. By utilizing the lifting and return of incompletely pulverized raw materials, the raw materials can form a circulating flow state within the feed hopper 1, thereby allowing for repeated and multiple pulverization processes until the raw materials meet the requirements and pass through the sieve holes 9. This continuous circulation design not only improves pulverization efficiency but also reduces raw material waste. Through multi-stage pulverization, especially the tearing and grinding processes, the cell walls of the small intestine can be more effectively broken down, making it easier for active ingredients such as heparin to be released, which helps to improve the heparin extraction rate in subsequent extraction steps. The raw materials are continuously introduced through the top opening of the feed hopper 1, and the pulverized raw materials are discharged through the sieve holes 9 and collected in the receiving hopper 10, realizing continuous production and improving production efficiency.

[0024] Furthermore, both the blade 6 on the shearing zone 4 and the blade 6 on the cone 3 are inclined, and the two ends of the blade 6 on the shearing zone 4 cooperate with the head end of one blade 6 and the tail end of the other blade 6 of two adjacent blades 6 on the cone 3 to form a shearing effect.

[0025] In detail, due to the rotation of the drum 2, the multiple blades 6 on the cone 3 and the multiple blades 6 on the shearing zone 4 need to be distributed in multiple rings. One ring of blades 6 on the shearing zone 4 is located between two adjacent rings of blades 6 on the cone 3. This allows the blades 6 on the cone 3 and the blades 6 on the shearing zone 4 to work together. Furthermore, since the two ends of the blades 6 on the shearing zone 4 can work with the head and tail ends of the two corresponding blades 6 on the cone 3, each blade 6 can achieve the effect of shearing at both ends. This can greatly improve the shearing efficiency and the crushing efficiency.

[0026] Because the blade 6 is inclined, the inclined surface of the blade 6 can be used to provide auxiliary thrust for the raw material, so that the raw material moves downward along the conical surface of the cone 3.

[0027] Furthermore, the rotating drum 2 and the cone 3 move at different speeds in the same direction, and a power unit is provided at the bottom of the material box 1 to provide rotational power for the rotating drum 2 and the cone 3.

[0028] In detail, since both the rotating drum 2 and the cone 3 can rotate in the same direction, the inclination direction of the upper blade 6 of the shearing zone 4 and the upper blade 6 of the cone 3 can be the same. Thus, each blade 6 can provide thrust to the raw material and achieve the shearing effect at both ends of the blade 6. Since the rotating drum 2 and the cone 3 move at different speeds, the upper blade 6 of the shearing zone 4 and the upper blade 6 of the cone 3 can achieve relative movement and shearing work.

[0029] Furthermore, a water storage chamber 11 is provided inside the rotating drum 2. The shape of the water storage chamber 11 is consistent with the shape of the rotating drum 2. A drain hole 12 communicating with the middle part of the rotating drum 2 is provided on the inner wall of the water storage chamber 11. The drain hole 12 is used to drain water to the middle part of the rotating drum 2.

[0030] In detail, the water storage chamber 11 is used to store water. When the equipment crushes the raw materials, the water can be continuously discharged into the middle of the rotating drum 2 through the drain hole 12. The water in the middle of the rotating drum 2 will wash the small intestine raw materials. Then the water will flow downwards on the cone 3 and be discharged through the screen hole 9. During this process, the water will carry the small intestine along the cone surface of the cone 3, thereby avoiding the small intestine from blocking the cone 3. At the same time, it is convenient to discharge the crushed small intestine through the screen hole 9, reducing the probability of coagulation between the small intestines and improving the continuity and smoothness of the equipment in processing raw materials.

[0031] Furthermore, an annular groove is provided at the bottom of the rotating drum 2, and a ring body 13 is vertically slidably arranged in the annular groove. The shearing zone 4 and the crushing zone 5 are both located at the bottom of the ring body 13. Multiple sliding rods 14 are vertically arranged at the top of the ring body 13. The top of the sliding rods 14 is slidably inserted into the water storage chamber 11. The sliding rods 14 are connected to the rotating drum 2 through a spring piece 15. The top of the annular groove is provided with multiple water inlets 16, which are connected to the water storage chamber 11. The material box 1 is provided with a water guiding structure for supplying water to the water storage chamber 11.

[0032] In detail, water is introduced into the water storage chamber 11 through the water guide structure. The water in the water storage chamber 11 can be introduced into the annular groove through the water outlet 16. Due to the water pressure, the water can push the ring body 13 downward. In this way, the distance between the ring body 13 and the cone body 3 can be adjusted by the water pressure. This makes it convenient to adjust the squeezing and crushing effect of the shearing zone 4 and the crushing zone 5 at the bottom of the ring body 13 on the raw materials. When the ring body 13 moves, it will drive the slide rod 14 to move, and the spring piece 15 will undergo elastic deformation.

[0033] Furthermore, the water guiding structure includes an annular groove plate 17 rotatably installed on the top of the inner wall of the material box 1. The space between the annular groove plate 17 and the material box 1 is sealed. The annular groove plate 17 is connected to the water storage chamber 11 through multiple water supply pipes 18. A water inlet pipe 19 connected to the annular groove plate 17 is provided on the top of the material box 1.

[0034] In detail, external water can be brought into the annular trough plate 17 through the water inlet pipe 19. The water in the annular trough plate 17 is introduced into the water storage chamber 11 through multiple water supply pipes 18. When the rotating drum 2 rotates, it will drive the annular trough plate 17 to rotate through the water supply pipes 18. The water inlet pipe 19 and the annular trough plate 17 remain in a connected state.

[0035] Furthermore, the top of the rotating drum 2 is provided with an air hole 20. The output end of the air hole 20 is inclined downward towards the axis of the rotating drum 2, and the input end of the air hole 20 extends downward into the water storage chamber 11. A float plate 21 is vertically slidably arranged in the water storage chamber 11, and the float plate 21 is used to block the input end of the air hole 20.

[0036] In detail, when the water supply pipe 18 supplies water to the water storage chamber 11, the air in the water storage chamber 11 can be discharged through the air hole 20, so that the water can easily fill the water storage chamber 11. When the water level reaches the position of the float plate 21, the water will cause the float plate 21 to float to the position of the air hole 20 input end and block it. At this time, the inside of the water storage chamber 11 is sealed.

[0037] Furthermore, the power unit includes a crossbeam 22 fixed in the middle of the rotating drum 2, a rotating column 23 is provided at the bottom of the crossbeam 22, a rotating sleeve 24 is provided at the bottom of the cone 3, the bottom of the rotating sleeve 24 extends to the bottom of the material box 1, the rotating sleeve 24 is rotatably connected to the material box 1, the bottom of the rotating column 23 passes through the cone 3 and the rotating sleeve 24, and both the cone 3 and the rotating sleeve 24 are rotatably connected to the rotating column 23; The bottom of the material box 1 is fixed with a bracket 25, and a motor 26 is installed on the bracket 25. The output end of the motor 26 is provided with a first transmission wheel 27 and a second transmission wheel 28. The first transmission wheel 27 and the second transmission wheel 28 are coaxially fixedly connected. The first transmission wheel 27 is connected to the rotating column 23 for transmission, and the second transmission wheel 28 is connected to the rotating sleeve 24 for transmission.

[0038] In detail, the bracket 25 can provide support for the motor 26, which can drive the first transmission wheel 27 and the second transmission wheel 28 to rotate synchronously. The first transmission wheel 27 and the second transmission wheel 28 drive the rotating column 23 and the rotating sleeve 24 to rotate synchronously. Since the rotating sleeve 24 is located outside the rotating column 23, the rotation speed of the rotating sleeve 24 will be slower than the rotation speed of the rotating column 23, thereby causing the cone 3 and the rotating cylinder 2 to perform differential motion in the same direction.

[0039] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
