Description

Technical Field

[0001] The utility model relates to the technical field of traditional Chinese medicine processing, and particularly relates to a traditional Chinese medicine pulverizing and mixing device. Background Art

[0002] The statements in this section only provide background information related to the disclosure of this application and may not constitute prior art.

[0003] As an important part of traditional Chinese medicine in China, the curative effect of traditional Chinese medicine is closely related to the pulverization degree of medicinal materials. The ultrafine pulverization technology can pulverize traditional Chinese medicinal materials to the micron or even nanometer level, significantly increasing the surface area of the medicinal materials, thereby improving the dissolution rate and bioavailability of active ingredients. In addition, ultrafine pulverization can also break the cell walls of medicinal materials, release more active ingredients, and enhance the medicinal effect. Therefore, the ultrafine pulverization technology has important application value in the modernization and internationalization process of traditional Chinese medicine.

[0004] At present, the ultrafine pulverization and mixing of traditional Chinese medicine mainly adopt mechanical pulverization method, air flow pulverization method, ultrasonic pulverization method, etc. The mechanical pulverization method impacts and shears the medicinal materials through high-speed rotating blades or hammers to achieve pulverization; the air flow pulverization method uses high-speed air flow to drive the medicinal material particles to collide with each other to achieve the pulverization effect; the ultrasonic pulverization method uses the cavitation effect of ultrasonic waves to make the medicinal materials generate high-frequency vibration in the liquid, thereby realizing ultrafine pulverization. These methods have their own advantages and disadvantages, but they can all achieve the ultrafine pulverization and mixing of traditional Chinese medicine to a certain extent.

[0005] However, it is found in the actual operation process that due to the increased surface area of the traditional Chinese medicine powder after ultrafine pulverization, it is easy to absorb moisture and agglomerate, resulting in difficult full mixing of various drug components, affecting the uniformity of the distribution of drug components, and further reducing the dissolution efficiency of the active ingredients of traditional Chinese medicine and the quality stability of subsequent preparations. Therefore, how to achieve the mixing uniformity of the traditional Chinese medicine powder after ultrafine pulverization is an urgent problem to be solved. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a traditional Chinese medicine pulverizing and mixing device to solve the problems that the powder is difficult to be evenly mixed after ultrafine pulverization and the traditional Chinese medicine powder is easy to absorb moisture and difficult to be evenly mixed.

[0007] The technical solution of the utility model is as follows:

[0008] A traditional Chinese medicine pulverizing and mixing device includes a pulverizing component and a mixing component that are communicated with each other. The pulverizing component includes a feed inlet and a discharge outlet. The pulverizing component is communicated with the mixing component through the discharge outlet, so that the pulverized material can be transported to the mixing component;

[0009] The mixing assembly comprises a mixer capable of controllably carrying and releasing medicine powder and a collecting container arranged below the mixer for receiving the medicine powder released from the mixer, and the mixer is rotatable.

[0010] Preferably, the mixer comprises a power element and a receiving element, wherein the receiving element is connected to one end of the power element, and driven by the power element, the receiving element can rotate around a vertical axis in a horizontal direction.

[0011] Preferably, the accommodating element is provided with a plurality of independent accommodating spaces. The sizes of the plurality of independent accommodating spaces are adjustable, for example, the plurality of independent accommodating spaces are separated by movable partitions. The discharge port of the pulverizing assembly is aligned with one of the independent accommodating spaces of the accommodating element, and the independent accommodating space to which the discharge port is aligned is changed by controlling the rotation of the accommodating element. Preferably, the discharge port is provided with a valve for controlling opening and closing.

[0012] Preferably, the discharge port can be configured as a conical discharge port.

[0013] Preferably, a plurality of through holes for leaking out the powder are provided below the independent accommodation space of the accommodation element. An on-off switch is provided at the position corresponding to the through hole. Preferably, the on-off switch is, for example, a rotary valve, a butterfly valve, a slide valve, a ball valve, etc. Specifically, for example, it can be a dust butterfly valve (V1FS / V2FS).

[0014] Preferably, the power element includes a motor and a rotating shaft, the output end of the motor is connected to the rotating shaft to drive the rotating shaft to rotate. The end of the rotating shaft away from the motor is connected to the accommodating element to realize that the motor drives the accommodating element to rotate.

[0015] Preferably, the motor can be installed at the lower part of the pulverizing assembly.

[0016] During operation, the motor can be controlled to control the rotation of the containing element, thereby changing the independent containing space aligned with the discharge port, and realizing the temporary storage of different powders in different independent containing spaces. After all kinds of powders are discharged, the motor is controlled to drive the containing element to rotate at high speed, and the switch is opened synchronously or delayed by 1-2 seconds, so that the powder in the containing element can fall into the collector below during rotation, and the powder in different containing spaces can be repeatedly stacked layer by layer in the collector based on rotation, thereby realizing efficient mixing.

[0017] Preferably, the on-off switch can be configured as follows: a separately controlled on-off switch is provided for each independent containing space, so that the discharge flow rate of each independent containing space can be independently controlled, thereby controlling the falling amount of each layer of medicine powder and achieving more precise quantitative mixing.

[0018] Preferably, a mixing chamber housing is provided outside the mixing assembly. The mixing chamber housing is hermetically connected to the housing of the pulverizing assembly and accommodates the discharge port of the pulverizing assembly and the mixing assembly.

[0019] According to a preferred embodiment, the traditional Chinese medicine pulverizing and mixing device further includes a gas environment control assembly. The gas environment control assembly includes a first air inlet provided above the side of the pulverizing assembly, a second air inlet provided above the side of the mixing assembly, and an air outlet provided below the mixing assembly.

[0020] Preferably, the air outlet is connected to a negative pressure device, and the first air inlet and the second air inlet are connected to a dry gas container. Valves are provided at the air outlet, the first air inlet, and the second air inlet. By controlling the opening and closing of the corresponding valves, the gas flow inside the traditional Chinese medicine pulverizing and mixing device can be controlled. For example, when the pulverizing assembly is working, the first air inlet and the air outlet are opened so that the gas flows from the pulverizing assembly to the mixing assembly, thereby assisting in promoting the outflow of the medicinal powder from the pulverizing assembly. When the mixing assembly is working, the first air inlet and the discharge port are closed, the second air inlet and the air outlet are opened, creating an air flow towards the aggregate collector to assist the medicinal powder in falling into the aggregate collector.

[0021] Preferably, the air outlet can be provided below the aggregate collector to guide the medicinal powder to fall into the aggregate collector and prevent the medicinal powder from flying around. The flow rate of the gas can be set according to actual needs. A support frame with through holes can be provided at the discharge port of the aggregate collector, so that the aggregate collector can support a filter paper with the help of the support frame. When in use, the filter paper is laid for use, and the filter paper is a filter paper through which gas can pass.

[0022] Such a setting also facilitates controlling the introduction of a low-temperature and dry air flow into the pulverizing assembly, facilitating the cooling of the materials during the pulverizing process, reducing the heat loss of the effective components of the materials during the pulverizing process, and at the same time, the relatively closed setting can prevent the finer powder materials from absorbing moisture and agglomerating.

[0023] Preferably, the feeding system of the pulverizing assembly can also be set as a fully enclosed feeding system. A material accommodating space is provided at the feeding port, and then after closing the feeding port, the feeding is closed under the operation of the gas environment control assembly, reducing the contact between the material and the outside air.

[0024] Compared with the existing technology, the beneficial effects of the present utility model are:

[0025] 1. A traditional Chinese medicine crushing and mixing device. The crushing and mixing device of the present application can, in actual application, be used for multiple-stage classification and mixing of multiple traditional Chinese medicine flavors in the same prescription at different particle size levels. For example, the first mixing is carried out at a coarse particle size, the second mixing is carried out at a fine particle size, and the third mixing is carried out at an ultra-fine particle size, thereby gradually reducing the crushing uniformity at the final ultra-fine crushing particle size and reducing the subsequent mixing difficulty. It can also mix the materials at different crushing output stages to improve the mixing uniformity.

[0045] Preferably, the motor can be installed at the lower part of the pulverizing assembly 100 .

[0046] During operation, the rotation of the containing element 212 can be controlled by controlling the rotation state of the motor, so that the discharge port 120 is aligned with different independent containing spaces 213, so that different powders can be discharged into different independent containing spaces 213 for temporary storage. After all kinds of powders are discharged, the motor is controlled to drive the containing element 212 to rotate at high speed, and the opening and closing switch of the bottom through hole is opened synchronously or delayed by 1-2 seconds, so that the powders in the containing element 212 can fall into the collector 220 below during rotation, and the powders in different independent containing spaces 213 can be repeatedly stacked layer by layer in the collector 220 based on rotation, so as to achieve efficient mixing.
