Description

Technical Field

[0001] The utility model relates to the technical field of medicinal material processing equipment, in particular to a vacuum feeding granulator. Background Art

[0002] In the field of processing Chinese medicinal materials, granules and tablets are common drug dosage forms. During the production process, the granules after granulation and drying often stick together, which affects the uniformity and fluidity of the granules. To solve this problem and ensure the product quality of granules and tablets, it is an essential step in the processing of medicinal materials to use a special granulator to disperse and adjust the particle size of the sticky particles. The granulator can maintain a good dispersion state of the particles after drying through mechanical forces such as rolling, friction and collision, while ensuring the physical stability of the granules. It can not only effectively disperse the sticky particles, but also obtain particles of uniform size that meet the drug production standards, thereby improving the efficacy of Chinese medicine preparations and the patient's medication compliance, and providing important technical support for the modern production of the Chinese medicine pharmaceutical industry.

[0003] For example, Chinese patent CN 220115679U discloses a vacuum feeding device for a swinging granulator, including a medicine powder storage bin, which is connected to an extrusion bin through a suction pipe, and a swinging granulator for granulation is installed at the lower end of the extrusion bin, and the extrusion bin includes a bin body connected to the suction pipe, which reduces the loss of medicine powder while enhancing the feeding effect. However, the above device has the following shortcomings in the specific application process: first, the inner groove design on the granulation disk may not be sufficient to provide sufficient dispersion, especially when dealing with medicine powder that is easy to stick after drying, there is a lack of rolling, friction and collision of particles; at the same time, the material is squeezed only through the mesh structure on the stainless steel screen, and the adhesion problem between particles is not solved thoroughly enough, which may lead to unsatisfactory particle dispersion effect and poor practicality.

They can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, ordinary technicians in the field should be able to understand other possible implementation methods and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0025] According to an embodiment of the utility model, a vacuum feeding granulator is provided.

[0026] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-Figure 6 As shown, the vacuum feeding granulator according to the embodiment of the utility model includes a feeding rack 1, a feeding box 2 is arranged at the top of the feeding rack 1, a vacuum feeding component 3 is arranged at the top of the feeding box 2, a discharging component 4 is penetrated through one side of the top of the vacuum feeding component 3, a granulating mechanism 5 is arranged at the bottom end of the discharging component 4, a discharging trough 6 is arranged at one side of the granulating mechanism 5, and trapezoidal support seats 7 are symmetrically arranged on both sides of the bottom end of the granulating mechanism 5.

[0027] With the aid of the above-mentioned technical scheme of the utility model, the structure of the utility model is scientific and novel, and can cooperate with the vacuum feeding component 3 and the discharging component 4 to perform precise mechanical force through the granulation mechanism 5 to roll, rub and collide the drug particles that are agglomerated and adhered after drying, thereby ensuring the dispersion state and physical stability of the drug particles after drying, effectively solving the problem of particle adhesion in the production of granules and tablets, and significantly improving the product quality of traditional Chinese medicine preparations.

[0028] In one embodiment, for the above-mentioned vacuum loading component 3 and discharging component 4, the vacuum loading component 3 includes a feeding chamber 301 arranged at the top of the feeding box 2, a feeding valve 302 is penetrated on one side of the feeding chamber 301, a conical loading pipe 303 is arranged on the top of the feeding chamber 301, a transition barrel 304 is arranged on the top of the conical loading pipe 303, a vacuum pump 305 is arranged on the top of the transition barrel 304, and an exhaust pipe 306 is arranged on one side of the top of the transition barrel 304; the discharging component 4 includes an L-shaped discharging pipe 401 arranged on one side of the top of the vacuum loading component 3, a discharging valve 402 is penetrated in the middle part of the top of the L-shaped discharging pipe 401, and a conical discharging pipe 403 connected to the granulating mechanism 5 is arranged at the bottom end of one end of the L-shaped discharging pipe 401, thereby realizing the negative pressure generated by the vacuum pump 305, efficiently transporting the material from the feeding box 2 to the granulating mechanism 5, and reducing the blockage and leakage of the material during the transportation process.

[0029] In addition, it should be noted that the vacuum pump 305 includes a pump body, a rotor, an intake valve, an exhaust valve, a filter and a discharge valve, wherein the pump body serves as a container for the various components in the pump and provides the necessary space for gas flow; the rotor rotates in the pump body and generates negative pressure through movement, thereby realizing gas extraction; the intake valve is connected to the transition barrel 304 through a pipeline, which is used to control the channel for materials to enter the vacuum pump, allowing air and materials to be sucked in when opened, and preventing materials from further entering when closed; the exhaust valve is connected to one end of the exhaust pipe 306, which is used to discharge the gas sucked by the vacuum pump; the filter is located in front of the intake valve of the vacuum pump, which can allow air to pass through and capture materials to prevent blockage; the discharge valve is connected to the L-shaped discharge pipe 401 through a pipeline, which is used to control the material from being transported to the granulation mechanism 5; this is a prior art and will not be elaborated here.

[0030] The working principle of the vacuum feeding assembly 3 and the discharge assembly 4 is as follows: the feeding chamber 301 is the first space where the material is sucked in, ensuring that the material is evenly distributed before being sucked by the vacuum pump, reducing the possibility of blockage and leakage. The feeding valve 302 is used to control the connection between the feeding chamber 301 and the conical feeding pipe 303. When it is opened, the material is allowed to be sucked in, and when it is closed, the flow of the material is stopped. The conical design of the conical feeding pipe 303 helps to guide the material flow to the vacuum pump and improve the feeding efficiency. The conical shape helps to prevent the material from adhering to the pipe wall. The transition barrel 304 is the middle part connecting the feeding chamber 301 and the vacuum pump 305. It can smooth the transition of the material flow and reduce the airflow disturbance caused by the direct connection. The vacuum pump 305 is the core power source of the entire feeding process. By generating negative pressure, the material is sucked and transported to the granulation mechanism 5 through the discharge assembly 4, while maintaining the sealing of the system. The exhaust pipe 306 releases the gas generated by the vacuum pump when sucking the material, which helps to maintain the vacuum degree of the device and prevent the feeding efficiency from being reduced due to gas accumulation.

[0031] The design of the L-shaped discharge pipe 401 allows the material to flow out of the vacuum feeding component 3 under the action of negative pressure, which is convenient for guiding the material to the granulation mechanism 5. The discharge valve 402 controls the flow of the material from the vacuum feeding component 3 to the granulation mechanism, and can be opened or closed to adjust the material transportation. The conical discharge pipe 403 connects the L-shaped discharge pipe 401 and the granulation mechanism 5, providing a transition area for the material to smoothly enter the granulation mechanism 5. The conical design helps to further reduce the blockage of the material during the transportation process, and can accelerate the flow of the material to the granulation mechanism 5, thereby improving the granulation efficiency.

[0033] The working principle of the granulation mechanism 5 is as follows: the granulation barrel 501 is the main working space for granulation of materials, the mounting ring 502 is used to fix the roller pressing assembly 506 so that the roller pressing assembly 506 can evenly roll the materials, the granulation outlet 503 is the channel for the granulated materials to flow to the discharge trough 6, the driving motor 504 provides power, and drives the granulation screen 505 to rotate inside the granulation barrel 501 through the output shaft, the granulation screen 505 is used to separate the materials, and the agglomerated particles are dispersed into granules and then fall into the bottom of the granulation barrel 501 through the sieve holes on the granulation screen 505, and the L-shaped guide plate 508 is used to guide the materials at the bottom of the granulation barrel 501 to flow to the granulation outlet 503.

[0034] When the material rotates with the particle discharging screen 505, it first passes between the roller pressing component 506 and the particle discharging screen 505. In the roller pressing component 506, a gap of a certain height is formed between the bottom end of the roller wheel 5063 and the particle discharging screen 505, and the agglomerated particles are dispersed into whole particles through the gap. Then, the material rotates with the particle discharging screen 505 to between the dispersion component 507 and the particle discharging screen 505, and the undispersed agglomerated particles are further evenly dispersed through the saw-shaped dispersion grooves 5074 on the J-shaped plate 5073 in the dispersion component 507, thereby improving the particle size reduction efficiency.
