Description

Technical Field

[0001] The invention relates to the technical field of medicinal material processing, and in particular to a Chinese medicinal material processing device with a waste gas recovery and treatment function. Background Art

[0002] The processing of Chinese herbal medicines is an important part of traditional Chinese medicine. It refers to the use of a series of processing methods to enhance the efficacy, reduce toxicity, change the medicinal properties or facilitate preservation. There are many processing methods, and the appropriate processing method should be selected according to different medicinal materials and clinical needs. The following are several common processing methods for Chinese herbal medicines: 1. Purification: remove non-medicinal parts and impurities from medicinal materials, such as peeling, core removal, and hair removal.

[0003] 2. Cutting: Cut the medicinal materials into different shapes such as slices, blocks, strips, and segments to facilitate the dissolution of the active ingredients during decoction.

[0004] 3. Stir-frying: Dry-fry in a pan or add auxiliary materials (such as bran, rice, soil) to stir-fry together to achieve the purpose of enhancing the efficacy or reducing toxic side effects.

[0005] 4. Steaming: Using steam to heat medicinal materials, often used for medicinal materials that need to be softened or have certain medicinal properties changed.

[0006] 5. Boiling: Put the medicinal materials into water and boil them for a certain period of time. Sometimes auxiliary materials are added and boiled together to soften the medicinal materials or change the medicinal properties.

[0007] 6. Roasting: Mix liquid auxiliary materials such as honey, wine, vinegar, etc. with medicinal materials and then heat them to enhance the efficacy or harmonize the medicinal properties.

[0008] 7. Calcination: Calcination of medicinal materials at high temperature is suitable for situations where the texture of the medicinal materials needs to become brittle and easy to crush or their pharmacological effects need to be changed.

[0009] 8. Fermentation: Through the action of microorganisms, the medicinal materials undergo chemical changes to produce new medicinal substances.

[0010] 9. Replication: Using specific compound prescriptions and processing them multiple times to improve drug efficacy or reduce adverse reactions.

[0011] At present, although there are equipment that can calcine, crush, and press-form medicinal materials, these operations are usually performed in different equipment, and there is no equipment that integrates the functions of calcining, crushing, and pressing. Therefore, it is necessary to transfer the medicinal materials between the calcining equipment, crushing equipment, and pressing equipment, which increases the operation time and labor intensity. Each switch from one equipment to another takes time, reducing the overall production efficiency. In addition, during the transfer process of medicinal materials, the medicinal materials are easily contaminated by the external environment, which may lead to a decline in product quality.

[0039] See also Figure 5-Figure 7 The molding die 12 comprises a frame 121 placed on the support plate 11, and an upper and lower mold core 122 which can be pulled out to the left is slidably provided in the frame 121, and a handle 123 is connected to the left side of the mold core 122, and a lifting block 124 is slidably connected to the left side of the frame 121 through a slide groove, and a push plate 125 located on the upper side of the mold core 122 is connected to the right side of the lifting block 124, and the pressing tool 15 comprises a sliding rod 151, a lifting rod 152, a semicircular pressing plate 153 and a spring 154, and the two mounting plates 14 are both slidably connected with the sliding rod 151 located on the upper side of the frame 121, and the left sides of the two sliding rods 151 are both slidably provided with a lifting rod 152, and a semicircular pressing plate 153 for extruding the powder is connected between the bottom ends of the two lifting rods 152, and the semicircular pressing plate 153 is located in the frame 121 and is tightly attached to the mold core 122, and the semicircular pressing plate 153 is located at the push plate On the right side of 125, two lifting rods 152 are each provided with a spring 154, and the two ends of the spring 154 are respectively connected to the semicircular pressure plate 153 and the slide bar 151, and the pulling mechanism includes two arc-shaped slide rails 161 respectively connected to the inner walls of the front and rear sides of the preparation box 1, and the two arc-shaped slide rails 161 are both slidably connected with a slider 162, and the slider 162 is fixedly connected to the outer wall of the insulation layer 2 33, and the front and rear two fixed plates 163 are connected to the right side of the top of the support plate 11, and the two fixed plates 163 are rotatably connected with fixed pulleys 164, and the right ends of the two slide bars 151 are connected with pull ropes 165, and the two pull ropes 165 are respectively passed around the two fixed pulleys 164, and the two pull ropes 165 are respectively connected to the two sliders 162, and the two slide bars 151 are each provided with a spring 2 166, and the two ends of the spring 2 166 are respectively connected to the slide bar 151 and the mounting plate 14.

[0040] The medicinal materials to be forged are poured into the feed hopper 4, and then the medicinal materials slide into the furnace body 31 through the feed hopper 4 and the feed channel 5. The electric heating tube 34 is controlled to heat the furnace body 31, so as to forge the medicinal materials. The heat loss can be reduced through the insulation layer 1 32 and the insulation layer 2 33, thereby improving the efficiency of medicinal material forging. The motor 1 8 is controlled to drive the crushing knife frame 9 to rotate slowly, which can stir the medicinal materials, so that the medicinal materials are heated evenly, and improve the efficiency and effect of medicinal material forging. After the medicinal materials are forged, the motor 1 8 is controlled to drive the crushing knife frame 9 to rotate at a high speed. The L-shaped crushing knife 92 on the crushing knife frame 9 rotates at a high speed to crush the forged medicinal materials. The isosceles triangle scraper plate 93 on the crushing knife frame 9 rotates at a high speed to shovel up the medicinal materials, so that the medicinal materials at the bottom of the furnace body 31 rise and hit the L-shaped crushing knife 92 for crushing. After the medicinal materials are crushed, the control motor 2 131 drives the gear set 132 to drive the rotating shaft 2 to rotate. The rotation of the rotating shaft 2 drives the electric calcining furnace 3 to rotate to the lower left, and the discharge channel 6 rotates to the lower left to the top of the forming mold 12. The electric calcining furnace 3 rotates to the lower left, driving the slider 162 to rotate to the upper left along the arc-shaped slide rail 161, thereby pulling the slide bar 151 to move to the right through the pull rope 165, and the spring 2 166 is stretched accordingly. The slide bar 151 moves to the right and drives the semicircular pressure plate 153 to move to the right through the lifting rod 152. The telescopic rod of the electric push rod 71 is controlled to extend to push the blocking plate 72 to move away from the discharge channel 6, thereby releasing the blockage of the discharge channel 6, and the powder in the electric calcining furnace 3 is poured onto the mold core 122 through the discharge channel 6. At the same time, the scraper 94 on the crushing blade holder 9 rotates to scrape off the powder adhering to the inner wall of the furnace body 31, so as to prevent a large amount of powder from adhering to and staying in the furnace body 31. After all the powder is poured out, the telescopic rod of the electric push rod 71 is controlled to shorten to pull the blocking plate 72 to move and reset to block the discharge channel 6 again. At the same time, the motor 2 131 is controlled to drive the gear set 132 to drive the rotating shaft 2 to reverse, and the rotating shaft 2 reverses to drive the electric calcining furnace 3 to rotate and reset to the upper right.

[0041] The electric calcining furnace 3 rotates to the upper right, driving the slider 162 to rotate to the lower right along the arc-shaped slide rail 161 to loosen the pull rope 165. Under the reset action of the spring 166, the slide bar 151 is pulled to the left to reset. The slide bar 151 moves to the left and drives the semicircular pressing plate 153 to move to the left through the lifting rod 152. The movement of the semicircular pressing plate 153 to the left can not only evenly smooth the powder in the material cavity on the mold core 122, but also cooperate with the upper mold core 122 to extrude the powder. The spring 154 can apply pressure to the semicircular pressing plate 153 to ensure that the powder is squeezed into sheets. The upper mold core 122 is pulled out from the frame 121 to the left. During this process, the medicine powder remaining on the top of the upper mold core 122 can be scraped off by the push plate 125, and the medicine powder on the top of the upper mold core 122 falls onto the lower mold core 122. After the upper mold core 122 is pulled out, under the action of gravity, the push plate 125 moves down and fits tightly against the lower mold core 122. Under the restoring action of the spring 154, the semicircular pressing plate 153 is pushed down and fits tightly against the lower mold core 122. Then the lower mold core 122 is pulled out to the left. During this process, the medicine powder remaining on the top of the lower mold core 122 can be scraped into the material cavity by the push plate 125, and the semicircular pressing plate 153 and the lower mold core 122 are forced by the spring 154 to cooperate to squeeze the medicine powder into sheets. After manually pouring out the Chinese herbal medicine pieces in the mold core 122, first pull the lifting block 124 to move the push plate 125 upward and reset it, and then put the two mold cores 122 back into the frame 121 in turn. When the lower mold core 122 is put back to the right into the frame 121, the lower mold core 122 pushes the semicircular pressure plate 153 to move upward to compress the spring 154. When the upper mold core 122 is put back to the right into the frame 121, the upper mold core 122 pushes the semicircular pressure plate 153 to move upward again, thereby compressing the spring 154 again. By replacing different types of mold cores 122, Chinese herbal medicine pieces of different specifications and shapes can be pressed out. In this way, the device can forge medicinal materials through the electric calcining furnace 3, and can crush the forged medicinal materials by driving the crushing blade holder 9 to rotate through the motor 18. Through the cooperation of the motor 2 131 and the gear set 132, the rotating shaft 2 can drive the electric calcining furnace 3 to rotate to the lower left, and the medicinal powder can be automatically poured into the forming mold 12. The medicinal powder can be pressed into shape through the cooperation of the pressing tool 15 and the forming mold 12, thereby achieving the effect of integrating calcination, crushing, and pressing and molding functions. There is no need to transfer medicinal materials back and forth, which shortens the operation time, reduces the labor intensity, improves the overall production efficiency of Chinese herbal medicines, reduces the risk of medicinal materials being contaminated by the external environment, and improves the quality of Chinese herbal medicines.

A fan 173 located in the shell 171 is installed on the right outer wall of the preparation box 1. The fan 1 173 is connected to the cyclone separator 172, and the fan 173 is connected to a telescopic tube 174, which penetrates the insulation layer 1 32 and extends into the furnace body 31. The air inlet end of the telescopic tube 174 is connected with a filter to prevent medicinal materials from entering the telescopic tube 174 and causing the telescopic tube 174 to be blocked. An air purifier 175 located on the lower side of the shell 171 is installed on the right outer wall of the preparation box 1, and a fan 2 176 is installed on the inner bottom of the shell 171. The fan 2 176 is connected to the cyclone separator 172 and the air purifier 175 through an air supply pipe 177.

[0043] When calcining medicinal materials, a large amount of waste gas and dust will be generated. The waste gas and dust are directly discharged into the air, which not only pollutes the environment, but also may have an adverse effect on the health of workers. Control the fan 173 to work, and input the waste gas and dust generated when calcining medicinal materials in the electric calcining furnace 3 into the cyclone separator 172 through the telescopic pipe 174. The cyclone separator 172 can separate gas and particulate matter. The gas is input into the air purifier 175 through the gas pipe 177 for purification. The purified gas is discharged from the air purifier 175, and the particulate matter is discharged downward from the cyclone separator 172. The cyclone separator 172 and the air purifier 175 are prior art and will not be described here. The particulate matter can be collected by the dust box 170.

The dynamic type is provided with three cages 188, which are located on the left side of the water tank 181 and on the lower side of the support plate 11. The lower parts of the inner walls on the front and rear sides of the preparation box 1 are spaced apart with three partitions 189 from bottom to top. The partitions 189 are used to separate two adjacent cages 188. The air pipe 177 connected to the air purifier 175 passes through the water tank 181. The air pipe 177 connected to the air purifier 175 is a copper pipe. The copper pipe has good thermal conductivity. The air pipe 177 connected to the air purifier 175 is wavy, which can extend the flow path of the hot air and fully recycle the heat energy.

[0045] Water is injected into the water tank 181 through the water injection pipe 182. The waste gas extracted from the electric calcining furnace 3 is hot gas. When the hot gas is transported to the air purifier 175 through the air pipe 177 passing through the water tank 181, the water in the water tank 181 absorbs the heat of the air pipe 177 inside it, so that the water in the water tank 181 is heated, thereby realizing the recovery and utilization of heat energy. After the medicinal materials are poured out of the electric calcining furnace 3, the fan 1 173 and the fan 2 176 are controlled to work synchronously, so that the residual hot gas in the electric calcining furnace 3 can be quickly transported to the air pipe 177 passing through the water tank 181, realizing the recovery and utilization of the residual heat energy. The medicinal materials to be steamed are placed on the steamer 188, and the water in the water tank 181 is heated to generate water vapor, which is discharged through the steam outlet 186 on the water tank 181 to steam the medicinal materials on the steamer 188. If the recovered heat energy is not enough to complete the steaming of the medicinal materials, the electric heater 187 can be controlled to heat the water in the water tank 181 to complete the steaming of the medicinal materials. The support plate 11 can block the steam to prevent the steam from entering the area above the support plate 11. When the pressure in the processing box 1 exceeds the set pressure of the pressure relief valve 184, the pressure relief valve 184 automatically opens to release the pressure (the pressure relief valve 184 is a prior art and is not repeated here), ensuring that the pressure in the processing box 1 is below the set pressure to prevent accidents. In this way, the device can recycle and utilize heat energy to steam medicinal materials, greatly improving energy utilization and reducing energy consumption.
