Description

Technical Field

[0001] The present invention relates to the technical field of crushing equipment, and particularly to a crusher for extracting heparin from small intestines. Background Art

[0002] Heparin is an important anticoagulant drug, widely used in multiple medical fields such as the prevention and treatment of thrombosis, cardiac surgery, hemodialysis, etc. It is mainly extracted from porcine small intestine mucosa or bovine lungs. With the growing global demand for heparin, improving its extraction efficiency and purity has become one of the key points of industry research. 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 methods, chemical methods, enzymatic methods, etc. Although these methods can meet the production requirements to a certain extent, they also have problems such as low raw material utilization rate, serious environmental pollution, and high costs. To overcome these problems, modern technologies are constantly exploring new extraction methods, such as ultrasonic-assisted extraction, microwave-assisted extraction, etc. Using a crusher as a pretreatment tool can significantly improve the crushing effect of raw materials and increase the release rate of active ingredients, thereby improving the efficiency of subsequent extraction steps.

[0004] Common crushers mainly directly crush the small intestine through the rotating blades inside. However, in this crushing method, since only the cutting method is used to complete the crushing of the small intestine, the small intestine cells cannot be effectively crushed, and the heparin release amount is small. Therefore, its improvement effect on heparin extraction is limited. Summary of the Invention

[0007] Furthermore, the rotating cylinder and the cone perform differential motion in the same direction. A power unit is arranged at the bottom of the feed bin, and the power unit is used to provide rotational power for the rotating cylinder and the cone.

[0008] Furthermore, a water storage chamber is arranged inside the rotating cylinder. The shape of the water storage chamber is the same as the outer shape of the rotating cylinder.

The sliding rods are connected to the rotating cylinder through elastic pieces; A plurality of water inlets are arranged at the top of the annular groove. The water inlets communicate with the water storage chamber, and a water guiding structure for supplying water into the water storage chamber is arranged on the feed bin.

[0010] Furthermore, the water guiding structure includes an annular groove plate rotatably installed at the top of the inner wall of the feed bin. The space between the annular groove plate and the feed bin is sealed. The annular groove plate and the water storage chamber are communicated through a plurality of water supply pipes. A water inlet pipe communicating with the annular groove plate is arranged at the top of the feed bin.

[0011] Furthermore, air holes are arranged at the top of the rotating cylinder. The output ends of the air holes are inclined downward towards the axis direction of the rotating cylinder.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations. This embodiment is written in a progressive manner.

[0020] As Figures 1 to 5 shown, a grinder for extracting heparin from the small intestine according to the present invention includes a material box 1, a rotating cylinder 2 and a cone 3 located inside the material box 1. The rotating cylinder 2 and the cone 3 are distributed vertically. A lifting channel is formed between the outer wall of the rotating cylinder 2 and the inner wall of the material box 1. The top of the rotating cylinder 2 is set as an inward concave conical surface, and a return material channel is formed between the top of the rotating cylinder 2 and the top of the inner wall of the material box 1. The area near the axis of the bottom of the rotating cylinder 2 is set as a shearing area 4, and the distance between the shearing area 4 and the upper surface of the cone 3 gradually decreases in the direction away from the axis of the rotating cylinder 2. The area far from the axis of the bottom of the rotating cylinder 2 is set as a grinding area 5, and the distance between the grinding area 5 and the upper surface of the cone 3 gradually decreases in the direction away from the axis of the rotating cylinder 2. A plurality of knife plates 6 are provided in the shearing area 4 and the corresponding upper surface area of the cone 3, and a plurality of protrusions 7 are densely distributed in the grinding area 5 and the corresponding upper surface area of the cone 3; A spiral plate 8 for pushing and lifting the raw material upward is provided in the lifting channel. The spiral plate 8 is fixed on the outer wall of the rotating cylinder 2. The lower side of the outer wall of the material box 1 is densely provided with sieve holes 9, and a receiving hopper 10 is encapsulated outside the sieve holes 9. The receiving hopper 10 is used to collect the crushed raw material; Among them, the raw material is introduced into the rotating cylinder 2 through the opening at the top of the material box 1.

[0021] Specifically, the rotary drum 2 can rotate relative to the cone 3 within the feed bin 1, such that the cutting plates 6, protrusions 7, and spiral plates 8 on the rotary drum 2 can all perform circular motion. The receiving hopper 10 covers the sieve holes 9 on the outer wall of the feed bin 1. When the crushed raw materials are discharged through the sieve holes 9, the receiving hopper 10 will collect the raw materials and discharge them naturally through the opening at the bottom of the receiving hopper 10. The space between the shearing area 4 and the cone 3 is larger than the space between the grinding area 5 and the cone 3.

[0022] During use, the raw materials are introduced into the middle of the rotary drum 2 through the top opening of the feed bin 1 and naturally fall onto the cone 3. The raw materials will slide obliquely along the conical surface of the cone 3 into the gap between the rotary drum 2 and the cone 3. The raw materials first enter the space between the shearing area 4 and the cone 3. The rotating cutting plates 6 on the rotary drum 2 will cooperate with the cutting plates 6 on the cone 3 to continuously shear the raw materials. The raw materials after shearing treatment enter the space between the grinding area 5 and the cone 3, and the moving protrusions 7 further tear and crush the raw materials. And in conjunction with the gradually decreasing distance between the grinding area 5 and the cone 3, the grinding effect on the raw materials can be achieved. In this way, the raw materials can undergo multiple crushing processes between the rotary drum 2 and the cone 3. The crushed raw materials are discharged to the vicinity of the sieve holes 9. The qualified raw materials will pass through the sieve holes 9 and be discharged into the receiving hopper 10, while the unqualified raw materials will be intercepted between the rotary drum 2 and the feed bin 1. By using the rotating spiral plate 8, the raw materials that are not thoroughly crushed can be lifted upward into the return channel and utilize the conical surface at the top of the rotary drum 2 to make the raw materials enter the rotary drum 2 again. The raw materials in the rotary drum 2 fall again and enter the space between the rotary drum 2 and the cone 3, thereby realizing the automatic return of unqualified raw materials and continuous crushing effect. During this process, new raw materials can be continuously introduced into the feed bin 1 through the top opening of the feed bin 1 for crushing, and the thoroughly crushed raw materials will be continuously discharged through the sieve holes 9, thereby realizing the continuous crushing work of the raw materials.

[0023] This crusher realizes the multi-stage crushing effect of raw materials by designing the shearing area 4 and the grinding area 5, effectively improving the crushing fineness of raw materials and increasing the release rate of active ingredients; by utilizing the lifting and returning work of unthoroughly crushed raw materials, the raw materials can form a circulating flow state within the feed bin 1, thereby enabling the raw materials to be crushed repeatedly and multiple times until the raw materials meet the requirements and pass through the sieve holes 9. This continuous circulation design not only improves the crushing efficiency but also reduces raw material waste; through multi-stage crushing, especially the tearing and grinding processes, the small intestinal cell walls can be more effectively damaged, 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 bin 1, and the crushed 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, the cutter plates 6 on the shredding area 4 and the cutter plates 6 on the cone 3 are both inclined. The two ends of the cutter plates 6 on the shredding area 4 cooperate with the head end of one cutter plate 6 and the tail end of another cutter plate 6 among two adjacent cutter plates 6 on the cone 3 to form a shearing effect.

[0025] Specifically, since the rotating cylinder 2 rotates, multiple cutter plates 6 on the cone 3 and multiple cutter plates 6 on the shredding area 4 need to be distributed in multiple circles. One circle of cutter plates 6 on the shredding area 4 is located between two adjacent circles of cutter plates 6 on the cone 3, so that the cutter plates 6 on the cone 3 and the cutter plates 6 on the shredding area 4 can cooperate with each other. And because the two ends of the cutter plates 6 on the shredding area 4 can cooperate with the head end and the tail end of two corresponding cutter plates 6 on the cone 3, each cutter plate 6 can achieve the working effect of shearing at both ends, which can greatly improve the shearing efficiency and the crushing efficiency.

[0026] Since the cutter plates 6 are inclined, the inclined surfaces of the cutter plates 6 can be used to provide auxiliary thrust for the raw materials, so that the raw materials move downward along the conical surface of the cone 3.

[0027] Furthermore, the rotating cylinder 2 and the cone 3 perform differential motion in the same direction. A power unit is arranged at the bottom of the feed box 1, and the power unit is used to provide rotational power for the rotating cylinder 2 and the cone 3.

[0028] Specifically, since both the rotating cylinder 2 and the cone 3 can rotate in the same direction, the inclination directions of the cutter plates 6 on the shredding area 4 and the cutter plates 6 on the cone 3 can be the same, so that each cutter plate 6 can be used to provide thrust for the raw materials and achieve the working effect of shearing at both ends of the cutter plates 6. Since the rotating cylinder 2 and the cone 3 perform differential motion, the cutter plates 6 on the shredding area 4 and the cutter plates 6 on the cone 3 can achieve relative motion and shearing work.

[0029] Furthermore, a water storage chamber 11 is opened inside the rotating cylinder 2. The shape of the water storage chamber 11 is the same as the outer shape of the rotating cylinder 2. Drainage holes 12 communicating with the middle part of the rotating cylinder 2 are opened on the inner side wall of the water storage chamber 11, and the drainage holes 12 are used to drain water into the middle part of the rotating cylinder 2.

[0030] Specifically, water is stored inside the water storage chamber 11. When the equipment crushes the raw materials, the water can continuously drain into the middle part of the rotating cylinder 2 through the drainage holes 12. The water in the middle part of the rotating cylinder 2 will wash the small intestine raw materials, and then the water will flow downward obliquely on the cone 3 and be discharged through the sieve holes 9. During this process, the water will carry the small intestine and move along the conical surface of the cone 3, so as to avoid blockage of the small intestine on the cone 3. At the same time, it is convenient to discharge the crushed small intestine through the sieve holes 9, reduce the probability of coagulation between the small intestines, and improve the coherence and smoothness of the equipment for raw material processing.

[0031] Further, an annular groove is formed at the bottom of the rotating cylinder 2. A ring body 13 is vertically slidably arranged in the annular groove. Both the shearing area 4 and the crushing area 5 are located at the bottom of the ring body 13. A plurality of 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 cylinder 2 through elastic pieces 15. A plurality of water inlets 16 are formed at the top of the annular groove. The water inlets 16 are communicated with the water storage chamber 11. A water guiding structure for supplying water into the water storage chamber 11 is arranged on the material box 1.

[0032] Specifically, water is introduced into the water storage chamber 11 through the water guiding structure. The water in the water storage chamber 11 can be introduced into the annular groove through the water inlets 16. Due to the action of water pressure, the water can push the ring body 13 downward. In this way, the distance between the ring body 13 and the cone 3 can be adjusted by the magnitude of the water pressure, which is convenient for adjusting the extrusion effect and crushing effect of the shearing area 4 and the crushing area 5 at the bottom of the ring body 13 on the raw materials. When the ring body 13 moves, it will drive the sliding rods 14 to move, and the elastic pieces 15 will undergo elastic deformation.

[0033] Further, the water guiding structure includes an annular groove plate 17 rotatably installed at 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 communicated with the water storage chamber 11 through a plurality of water supply pipes 18. A water inlet pipe 19 communicated with the annular groove plate 17 is arranged at the top of the material box 1.

[0034] Specifically, external water can be brought into the annular groove plate 17 through the water inlet pipe 19. The water in the annular groove plate 17 is introduced into the water storage chamber 11 through a plurality of water supply pipes 18. When the rotating cylinder 2 rotates, it will drive the annular groove plate 17 to rotate through the water supply pipes 18, and the water inlet pipe 19 and the annular groove plate 17 remain in a communicating state.

[0035] Further, air holes 20 are formed at the top of the rotating cylinder 2. The output end of the air holes 20 is inclined downward towards the axis direction of the rotating cylinder 2. The input end of the air holes 20 extends downward into the water storage chamber 11. A floating plate 21 is vertically slidably arranged in the water storage chamber 11. The floating plate 21 is used to block the input end of the air holes 20.

[0036] Specifically, when the water supply pipes 18 supply water into the water storage chamber 11, the air in the water storage chamber 11 can be discharged through the air holes 20, so as to facilitate filling the water storage chamber 11 with water. When the water level reaches the position of the floating plate 21, the water will cause the floating plate 21 to float to the position of the input end of the air holes 20 and block it. At this time, the inside of the water storage chamber 11 is sealed.

[0037] Furthermore, the power unit includes a cross beam 22 fixed to the middle of the rotating cylinder 2. A rotating column 23 is provided at the bottom of the cross beam 22. A rotating sleeve 24 is provided at the bottom of the cone 3. The bottom of the rotating sleeve 24 extends below 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; A bracket 25 is fixed to the bottom of the material box 1. A motor 26 is provided on the bracket 25. A first transmission wheel 27 and a second transmission wheel 28 are provided at the output end of the motor 26. The first transmission wheel 27 and the second transmission wheel 28 are coaxially and fixedly connected. The first transmission wheel 27 is in transmission connection with the rotating column 23, and the second transmission wheel 28 is in transmission connection with the rotating sleeve 24.

[0038] Specifically, the bracket 25 can support the motor 26. The motor 26 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 rotational speed of the rotating sleeve 24 will be slower than that of the rotating column 23. Thus, the cone 3 and the rotating cylinder 2 perform a differential motion in the same direction.

[0039] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and deformations can be made, and these improvements and deformations should also be regarded as the protection scope of the present invention.
