Description

Technical Field

[0001] This utility model relates to the field of heparin sodium production technology, and in particular to a crushing device for heparin sodium production. Background Technology

[0002] Heparin sodium is a sodium sulfated aminoglucan salt extracted from the internal organs (mainly the small intestinal mucosa and lungs) of animals such as pigs, cattle, and sheep. It belongs to the mucopolysaccharide class of compounds. Its molecules are strongly acidic and carry a large number of negative charges. It can bind to antithrombin III and rapidly inhibit coagulation factors IIa and Xa, making it one of the most commonly used rapid anticoagulant drugs. However, the pulverizing device plays a core role in the "post-drying treatment" of heparin sodium production. Its pulverization particle size, temperature control, cleaning verification, and explosion-proof safety directly determine the product quality, yield, and compliance.

[0003] However, existing technologies still have the following problems: The raw material crushing device for heparin sodium production grinds the material using a spiral blade, and finally expels it through the discharge hole in the honeycomb sealing plate, making the material more thoroughly crushed. However, during the crushing process, some raw materials get stuck in the tooth grooves of the crushing gear shaft, and some fall above the baffle, which not only wastes resources but also contaminates other heparin sodium raw materials in the long run, thus reducing product quality. Therefore, our company provides a new crushing device for heparin sodium production to solve the above technical problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a new technical solution for the fan-shaped movement of the baffle in a crushing device for heparin sodium production.

[0005] The purpose of this utility model is achieved as follows: A crushing device for heparin sodium production includes a housing with a feed hopper at the top and a door hinged to the outside of the housing. A collection box is located at the bottom of the housing and communicates with the interior of the housing. A stirring shaft is rotatably installed inside the collection box, and a discharge pipe is installed at one end of the stirring shaft. A power mechanism is located on one side of the housing and is connected to one end of a crushing gear shaft. An anti-retention mechanism is located inside the housing near the housing door. The anti-retention mechanism consists of a baffle and a fan-shaped wheel rocker mechanism. The baffle is arranged crosswise with the crushing gear shaft, and the crushing gear shaft is driven by the fan-shaped wheel rocker mechanism, thereby causing the baffle to swing in a fan shape.

[0006] Optionally, the power mechanism includes a motor, and a transmission mechanism is keyed to one end of the motor output shaft. The transmission mechanism includes a first pulley and a second pulley, with a coaxial belt embedded on the first pulley and the second pulley. The second pulley is fixedly connected to the crushing gear shaft.

[0007] Optionally, two sets of rotating holes are provided on one side of the box body, and two sets of gears are provided at one end of the two sets of crushing gear shafts through the rotating holes, and the two sets of gears mesh with each other.

[0008] Optionally, the sector gear rocker mechanism includes a rocker arm and a sector wheel, wherein the rocker arm is fixedly connected to one end of the crushing gear shaft, and the sector wheel is fixedly connected to one end of the stop body.

[0009] Optionally, a rotating pin is fixedly connected to both the rocker arm and the sector wheel, and a connecting rod is connected between the two sets of rotating pins, with the connecting rod rotatably connected to both the rocker arm and the sector wheel.

[0010] Optionally, the cabinet door is rotatably mounted with a buckle, the buckle engaging in a slot, and the slot being fixedly connected to the cabinet.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the baffle of the crushing device for heparin sodium production uses a sector gear rocker mechanism to make the baffle move in a sector shape. This sector movement can effectively prevent the raw materials from accumulating on the baffle during the crushing process, thereby avoiding resource waste and potential product contamination problems. In addition, this design can also improve the operating efficiency of the equipment, reduce the frequency of manual cleaning, and reduce maintenance costs.

[0012] Meanwhile, due to the meshing relationship between the baffle and the crushing gear shaft, the movement of the baffle can also assist the crushing process, further improving the overall performance of the device.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-7 As shown, a crushing device for heparin sodium production includes a sealed box 1. A feed hopper 3 is located at the top of the box 1 for material feeding. An openable box door 2 is installed on the side of the box 1 for easy maintenance and repair. A collection box 19 is located at the bottom of the box 1 for collecting the processed material. A stirring shaft 16 is installed inside the collection box 19. One end of the stirring shaft 16 is fitted with a discharge pipe 10. The stirring shaft 16 is driven by a power mechanism to rotate, and the rotation of the stirring shaft 16 drives the crushed raw material from... The material is discharged through the discharge pipe 10. The power mechanism is connected to one end of the crushing tooth shaft 17. Two sets of crushing tooth shafts 17 are provided. These two sets of crushing tooth shafts 17 mesh with each other through the power mechanism to form a crushing area. Near the working area of ​​the crushing tooth shaft 17, an anti-retention mechanism is specially set up. This mechanism is mainly composed of a baffle 18 and a fan-shaped wheel rocker mechanism. The baffle 18 realizes repeated fan-shaped swinging between the crushing tooth grooves through the transmission action of the fan-shaped wheel rocker mechanism, which effectively prevents the material from being adsorbed and retained between the crushing tooth grooves during the crushing process of the crushing tooth shaft 17.

[0025] Specifically, the power mechanism mainly consists of a motor 11 and its matching transmission system. The motor 11 serves as the power source, and one end of its output shaft is fixedly connected to the transmission mechanism via a key connection. The transmission mechanism adopts a belt drive method and mainly consists of a first pulley 12, a second pulley 14, and a coaxial belt 13 connecting the two. The first pulley 12 is directly mounted on the motor output shaft, while the second pulley 14 is arranged in an appropriate position as a driven pulley. The two pulleys achieve synchronous transmission through the coaxial belt 13, thereby efficiently transmitting the power of the motor to the subsequent working parts.

[0026] Specifically, the housing 1 has two sets of symmetrical rotating holes on the side near the power mechanism. The two sets of crushing gear shafts 17 are connected by gears 15. One set of gears 15 not only meshes with the other set of gears 15, but is also firmly fixed to the transmission mechanism by a key connection. The transmission mechanism finally transmits power to the second pulley 14, thereby ensuring the coordinated operation of the entire crushing system.

[0027] Specifically, the sector gear rocker mechanism mainly consists of two core components: a rocker arm 4 and a sector wheel 7. The rocker arm 4 is fixedly connected to one end of the crushing gear shaft 17 by welding or bolting. At the same time, the sector wheel 7 is fixedly connected to one end of the stop body 18 in the same way as the rocker arm 4, forming a complete transmission system. The structure of the sector gear rocker mechanism also includes two sets of rotating pins 5. These two sets of rotating pins 5 play a connecting and transmission role in the mechanism. One set of rotating pins 5 is fixedly connected to the lower end of one side of the rocker arm 4, serving as the fulcrum for the rocker arm's movement. The other set of rotating pins 5 is fixedly connected to one end of one side of the sector wheel 7. The two sets of rotating pins 5 are rotatably connected by a connecting rod 6. This structural design allows the rotational movement of the rocker arm 4 to be converted into a specific sector-shaped movement trajectory of the stop body 18 through the connecting rod 6. The sector-shaped oscillation of the stop body 18 can cause the material on the stop body 18 to fall into the collection box 19 due to inertia, thereby solving the problem that some raw materials will fall above the baffle.

[0028] Specifically, the cabinet door 2 is rotatably mounted with an L-shaped buckle 8 via a rotating shaft structure. The end of the buckle 8 is designed with a protruding structure, which can be precisely embedded and locked into the rectangular slot 9 opened on the side wall of the cabinet 1. The slot 9 is firmly connected to the main frame of the cabinet 1 by welding or bolting, forming a reliable locking mechanism. When the cabinet door 2 is closed, the buckle 8 will automatically align with the position of the slot 9 during rotation, realizing the function of quick locking and unlocking.

[0029] The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
