Description

Technical Field

[0001] This utility model belongs to the field of traditional Chinese medicine production equipment, and in particular relates to a stirring device for Shenqu (a type of medicinal herb). Background Technology

[0002] Shenqu is a traditional Chinese medicine. It is a fermented starter made by adding Polygonum hydropiper, Artemisia annua, almond paste, red adzuki beans, and fresh Xanthium sibiricum to flour or wheat bran. The processing of Shenqu requires mixing the raw materials, and sometimes yeast or other fermenting bacteria are added during the mixing process. To ensure fermentation efficiency, the humidity during mixing must be controlled. Therefore, general-purpose mixing devices cannot meet the processing requirements of Shenqu. Furthermore, the mixed raw materials often stick to the hopper, requiring manual assistance for unloading. Therefore, the applicant proposes a mixing device suitable for Shenqu processing to overcome the unavoidable defects of existing mixing devices in Shenqu processing. Utility Model Content

[0003] The purpose of this utility model is to provide a Shenqu (a type of Chinese medicinal herb) mixing device to solve the defects of existing mixing devices in processing Shenqu, such as difficulty in unloading materials and inability to humidify and heat the mixture. To achieve this purpose, the specific technical solution is as follows:

[0004] A stirring device for a medicinal liquor includes: a base, a housing, a hopper, an outer sprocket for the hopper, a stirring shaft, bearing seats, stirring blades, a stirring motor, a discharge motor, a controller, a control panel, a steam pipe, a steam pressurizing pump, a steam solenoid valve, a hopper cover, and a nozzle. Bearing seats are located on both sides of the base. The two ends of the stirring shaft are mounted on the bearing seats on both sides. The stirring shaft has a hollow structure with several air holes distributed on it. The hopper is installed in the middle section of the stirring shaft between the two bearing seats. Outer sprockets are installed on both sides of the hopper at the connection points with the stirring shaft. The outer sprockets are fixed to the side walls of the hopper with screws. Stirring blades are installed on the part of the stirring shaft inside the hopper. The stirring motor is fixed to the base inside the housing on one side. A transmission sprocket is located at the end of the stirring shaft near the stirring motor. The transmission sprocket and the drive sprocket on the output shaft of the stirring motor are connected by a transmission chain. The discharge motor is located in the housing on the same side as the stirring motor and fixed to the base. The drive sprocket on the output shaft of the discharge motor is connected to the nearby hopper via a transmission chain. The outer sprocket is connected, and the other side of the machine box has an access hole for the steam pipe. The steam pipe is connected to the other end of the stirring shaft through a rotating flange. The steam pressurizing pump, steam solenoid valve and controller are installed in the same side of the machine box. The steam solenoid valve is installed on the steam pipe. The steam pipe inside the steam solenoid valve is also equipped with a hose connector. The controller is installed on the inner wall of the machine box, and the control panel is installed on the outer wall of the same side of the machine box. The input end of the controller is electrically connected to the control panel, and the output end of the controller is electrically connected to the control modules of the steam solenoid valve, steam pressurizing pump, stirring motor and unloading motor. The two outer walls of the hopper cover are connected to the two outer walls of the hopper through two self-locking gas springs. The self-locking gas springs are fixedly connected to the side walls of the hopper cover and the outer walls of the hopper through screws. The bottom surface of the hopper cover at the far end in the unloading direction is equipped with a nozzle mounting bracket. Several nozzles are installed on the nozzle mounting bracket. The nozzles are connected to the steam pressurizing pump through hoses embedded in the hopper cover. The steam pressurizing pump is connected to the hose connector on the steam pipe through a hose.

[0005] Furthermore, a bearing is provided at the connection between the hopper and the stirring shaft.

[0006] Furthermore, the stirring blades adopt a spiral structure.

[0007] Furthermore, the controller adopts a Siemens S7-300 programmable controller.

[0008] Furthermore, the control panel adopts an industrial embedded LCD control panel.

[0009] Furthermore, a pressure relief port is provided above the bucket cover.

[0010] Furthermore, the nozzles on the nozzle mounting bracket are arranged in a fan shape.

[0011] Furthermore, the air holes on the stirring shaft are equipped with filter screens.

[0012] The beneficial effects of this utility model are:

[0013] (1) This utility model can introduce hot steam during the mixing process to regulate the temperature and humidity requirements in the hopper. On the one hand, it can better mix raw materials and kill harmful bacteria. On the other hand, it can achieve pre-fermentation during mixing when needed.

[0014] (2) The present invention has air holes on the stirring shaft. In addition to spraying hot steam, the air holes will generate rotating airflow during the rotation of the stirring shaft to assist in mixing, avoid raw material accumulation, and improve mixing efficiency.

[0015] (3) The present invention has a number of fan-shaped nozzle groups on the bottom surface of the hopper cover. These nozzles adopt independent pipeline solenoid valves and steam pressurization pumps, which can pressurize and spray air onto the inner wall of the hopper when the steam input to the stirring shaft is stopped (i.e. when unloading), making it easier to unload the mixture with a certain viscosity. The automatic unloading function is realized in conjunction with the hopper outer sprocket and unloading motor on the outer wall of the hopper. Attached Figure Description

[0023] Preferably, a bearing is provided at the connection between the hopper 3 and the stirring shaft 5.

[0024] Preferably, the stirring blade 7 adopts a segmented spiral structure.

[0025] In a preferred embodiment, the controller 10 is a Siemens S7-300 programmable controller.

[0026] In a preferred embodiment, the control panel 11 is an industrial embedded LCD control panel.

[0027] Preferably, a pressure relief port 17 is provided above the bucket cover 15.

[0028] Preferably, the nozzles 16 on the nozzle 16 mounting bracket are arranged in a fan shape.

[0029] Preferably, the air holes on the stirring shaft 5 are equipped with filter screens.

[0030] The wiring method between the controller and the control panel is as follows:

[0031] The controller uses a Siemens S7-300 controller, such as SM321. One end of each button contact (normally closed) on the control panel is connected to the positive terminal (L+) of the 24VDC power supply, and the other end is connected to the PLC input terminal (such as I0.0, I0.1, etc.).

[0032] The wiring method between the controller and the steam booster pump is as follows:

[0040] Working principle:

[0041] The staff lifts the hopper lid, which is supported by a self-locking gas spring to create a certain space between the lid and the hopper. The lid and the self-locking gas spring are connected by a hinge, so the lid can be tilted to feed the material. After the staff puts the raw material into the hopper, they press down the lid to make it coincide with the hopper opening plane. Then, they control the stirring motor through the control panel to start the stirring shaft and drive the stirring blades to start rotating. When needed (for situations requiring temperature and humidity control or fermentation), the steam solenoid valve is opened through the control panel, and at the same time, steam at the appropriate temperature is introduced into the stirring shaft through the steam pipe. The steam is sprayed out from the air hole on the stirring shaft and the nozzle on the nozzle holder to cooperate with the stirring.

[0042] After mixing is completed, the operator controls the mixing motor to turn off on the control panel, closes the steam solenoid valve, turns on the steam pressurization pump and starts the unloading motor to unload the material. The unloading motor drives the outer sprocket of the hopper on the same side to rotate, thereby tilting the hopper to unload the material. At the same time as unloading, pressurized steam is sprayed out from the nozzle, and the airflow forms a path along the inner wall of the hopper to assist in unloading.
