An integrated device for crushing and grinding Chinese medicinal herbs

Abstract

This invention discloses an integrated device for crushing and grinding Chinese herbal medicine slices, belonging to the field of Chinese herbal medicine slice processing technology. It includes a toothed disc pulverizer and a self-cleaning component. The self-cleaning component is used to rinse and dry the inner cavity of the pulverizing chamber, the moving disc, the first fixed toothed disc, the machine compartment door, and the second fixed toothed disc. By incorporating the self-cleaning component, the invention automatically opens the machine compartment door using a drive unit and seals the material discharge port with the rinsing and drainage unit. This eliminates the need for manual disassembly of the toothed disc and inner cavity components, completing the entire process of rinsing, soaking, drainage, and drying. This significantly reduces downtime associated with traditional manual disassembly and cleaning, improving equipment utilization. Furthermore, by separating the second fixed toothed disc from the moving disc, and coordinating the low-speed rotation of the moving disc in the cleaning solution, the water flow disturbance achieves comprehensive rinsing of the uneven surfaces of the pulverizing chamber, the first fixed toothed disc, the moving disc, and the second fixed toothed disc, thoroughly eliminating blind spots that are difficult to reach by manual wiping.

Description

Technical Field

[0001] This invention relates to the field of traditional Chinese medicine processing technology, specifically an integrated device for crushing and grinding traditional Chinese medicine. Background Technology

[0002] Traditional Chinese medicine (TCM) decoction pieces refer to Chinese medicinal herbs that have undergone processing and can be directly used in TCM clinical practice. During the processing of TCM decoction pieces, depending on the type of medicinal material and the therapeutic needs, some herbs require crushing or grinding.

[0003] Enhance drug efficacy and utilization: Break down cell walls to allow for the direct release of components that are difficult to dissolve in water, which can significantly increase the absorption rate by 14-40 times;

[0004] Convenient for administration and dispensing: It is easy to swallow directly and can be made into pills, powders, ointments and elixirs without the need for decoction;

[0005] Reduce irritation to the stomach and intestines: Fine grinding can remove some of the hard parts of the medicinal materials that may irritate the stomach and intestines.

[0006] The toothed disc pulverizer is the most common crushing and grinding equipment in the field of traditional Chinese medicine pulverization, also known as the "universal pulverizer". It achieves material pulverization and grinding through the impact, shearing, and friction between the high-speed rotating moving toothed disc and the fixed toothed disc. It is especially good at processing dry and brittle Chinese medicinal materials. Its working principle is as follows:

[0007] The motor drives the movable toothed disc (moving disc) to rotate at speeds up to 25,000 revolutions per minute, creating a high-speed relative motion with the stationary toothed disc (fixed disc). After the material enters, it is subjected to repeated impacts, shearing, friction, and collisions between the moving and stationary teeth, resulting in rapid pulverization. The pulverized material is then thrown towards the discharge port by airflow or centrifugal force. Only particles smaller than the screen mesh size can pass through, ensuring the fineness of the finished product. The fineness can be adjusted by changing the screen mesh size, typically ranging from 12 to 300 mesh.

[0008] When crushing and grinding Chinese medicinal herbs using a toothed disc pulverizer, after processing a single batch of herbs, the inner cavity of the equipment needs to be cleaned. The main process is as follows: "Safe shutdown → disassembly and cleaning → wiping the inner cavity → drying and disinfection → resetting and inspection".

[0009] During this process, the disassembly and assembly of the gear plate takes up a long working time, and the surface of the fixed gear plate is uneven. Manual wiping is not only inefficient, but also prone to creating cleaning dead corners.

[0010] Based on this, in order to achieve efficient cleaning of the inner cavity of the toothed disc pulverizer, an integrated device for crushing and grinding Chinese herbal medicine slices with self-cleaning function is provided. Summary of the Invention

[0056] The switching units are located at the bottom of the base 101 and are connected to the drive unit; the flushing and sewage discharge unit is installed on the switching units.

[0061] There are two connecting rods 207, which are symmetrically fixed to the front end of the cabin door cover 107 and connected and fixed to the connecting cross arm 206.

[0062] The first hydraulic cylinder 205 is used to move the engine compartment door cover 107 back and forth, thereby switching between working mode and cleaning mode;

[0063] The switching unit includes an L-shaped connecting frame 208 and a discharge port 209;

[0064] The discharge port 209 is distributed on the lower surface of the machine base 101, and the top port of the discharge port 209 is aligned with the discharge port 111, which is used to receive and guide the processed powder.

[0065] The L-shaped connecting frame 208 is connected to the bottom of the connecting cross arm 206 and the front end of the unloading pipe port 209 to realize the synchronous movement of the unloading pipe port 209 and the engine room door cover 107.

[0066] The flushing and sewage discharge unit includes a fixed platform 212, a second hydraulic cylinder 213, a sealing cover 214, a drain outlet 215, and a water inlet pipe 216;

[0067] The fixed platform 212 is fixed to the rear end of the unloading pipe 209. The second hydraulic cylinder 213 is installed at the bottom of the fixed platform 212 and the piston rod of the second hydraulic cylinder 213 extends through to the top of the fixed platform 212 and is connected and fixed to the sealing cover 214.

[0068] Drain outlet 215 and water inlet pipe 216 are symmetrically fixed on both sides of the bottom of the sealing cover 214. Drain outlet 215 is connected to the inner cavity of sealing cover 214. Water inlet pipe 216 extends to the inner side of sealing cover 214 and is connected to nozzle 217. Nozzle 217 is fixed on the arc part of water inlet pipe 216 and is connected to the inner cavity of water inlet pipe 216.

[0069] The guide rod 211 is distributed by inserting the sealing cover 214 into the inside of the guide rod 211. The water inlet pipe 216 is connected to the external water pipe to provide water source for rinsing the inner cavity of the crushing chamber 102. The drain outlet 215 is used to provide a discharge channel for some residual cleaning water.

[0070] In this embodiment, it should be noted that: the sewage outlet 202 is connected to the main sewage pipe or sewage collection container through a valve; the hot air inlet 203 is connected to the air outlet of the hot air blower or electric hot air generator through a valve; the drain outlet 215 is connected to the collection system of the sewage outlet 202 through a valve and a hose; and the water inlet pipe 216 is connected to a water supply device (e.g., a booster pump, a pure water storage tank, or a tap water pipe) through a hose.

[0071] The working principle of this integrated device for crushing and grinding Chinese herbal medicine slices is as follows:

[0072] During crushing: The drive motor 110 drives the horizontal shaft 103 and the moving disc 104 to rotate at high speed through belt transmission. The material enters the inner cavity of the crushing chamber 102 from the feed inlet 109. In the interlacing gap between the high-speed rotating moving disc 104 and the stationary first fixed toothed disc 105 and second fixed toothed disc 108, it is subjected to repeated impact, shearing and friction, and is quickly crushed and ground. The crushed material is thrown towards the annular screen 106 under the action of centrifugal force. Powder with a particle size smaller than the screen aperture passes through the screen and is discharged from the bottom discharge port 111, and is discharged through the discharge pipe port 209, completing the crushing process. (It should be noted that in the working mode, the piston rod of the first hydraulic cylinder 205 is in a retracted state, and the machine compartment door 107 is tightly fitted to the front end of the crushing chamber 102.)

[0073] During cleaning: When cleaning is required, the self-cleaning component 2 is activated. The two symmetrically fixed first hydraulic cylinders 205 drive the connecting cross arm 206 forward through the extension of the piston rod. The connecting cross arm 206 drives the cabin door cover 107 to slide horizontally forward along the inner wall of the fixed ring chamber 201 through the two connecting rods 207. The cabin door cover 107 separates from the crushing chamber 102. At the same time, it drives the second fixed toothed disc 108 to separate from the moving disc 104. The crushing chamber 102 is connected to the inner cavity of the fixed ring chamber 201. The ports of the sewage outlet 202 and the hot air inlet 203 are located in the middle area between the second fixed toothed disc 108 and the moving disc 104. At this time, the device switches to the cleaning mode to provide space for subsequent rinsing and drying.

[0074] Meanwhile, when the first hydraulic cylinder 205 drives the connecting cross arm 206 to move, the unloading port 209 is synchronously driven through the L-shaped connecting frame 208 to achieve linkage with the engine room door cover 107. In the working mode, the unloading port 209 is aligned with the discharge port 111 for normal material discharge. In the cleaning mode, the unloading port 209 moves forward, and the flushing and sewage discharge unit installed at its rear end moves to directly below the discharge port 111 to prepare for sealing and flushing operations.

[0075] When the unloading pipe 209 moves into place, the sealing cover 214 is located directly below the discharge port 111. At this time, the second hydraulic cylinder 213 is activated, and its piston rod pushes the sealing cover 214 upward, so that the sealing cover 214 is inserted into and closes the discharge port 111.

[0076] At this time, external water enters through the inlet pipe 216 and sprays out from the nozzle 217 to rinse the inner cavity of the crushing chamber 102 and fill the crushing chamber 102 and the fixed ring chamber 201 with the cleaning water. The inner cavity of the crushing chamber 102, the first fixed toothed disc 105, the moving disc 104, and the second fixed toothed disc 108 are immersed in the cleaning water. At this time, the drive motor is started synchronously to make the moving disc 104 rotate. The rotation of the moving disc 104 disturbs the water flow, so that the water flow can achieve all-round rinsing of the inner cavity of the crushing chamber 102, the first fixed toothed disc 105, the moving disc 104, and the second fixed toothed disc 108.

[0077] After a period of agitation and rinsing, open the valve of sewage outlet 202 to discharge sewage through sewage outlet 202. During this process, keep the water inlet pipe 216 in the water inlet state so that the cleaning sewage in the pulverizing chamber 102 is fully flushed away. After the sewage is completely discharged, stop the water inlet and continue to drain through sewage outlet 202. Finally, there will be a small amount of cleaning water in the pulverizing chamber 102. At this time, open the valve of drain outlet 215 and the remaining small amount of cleaning water is discharged through drain outlet 215. At this time, the rinsing operation is completed.

[0078] After rinsing, open the valve of hot air inlet 203 to allow hot air to enter from hot air inlet 203 and into the inner cavity of fixed ring chamber 201 and crushing chamber 102 to perform drying operation inside. The drying hot air can be discharged through feed inlet 109.

[0079] After cleaning is completed, the second hydraulic cylinder 213 and the first hydraulic cylinder 205 are reset in sequence. The overall operation is simple, convenient and efficient, which can effectively shorten the working time occupied by cleaning.

[0080] Please refer to this carefully. Figure 3 , Figure 5 , Figures 7 to 10 The outer wall dimensions of the sealing cover 214 match the inner wall dimensions of the discharge port 111, and the top of the sealing cover 214 has an arc-shaped trajectory, which matches the circular trajectory of the inner cavity of the crushing chamber 102.

[0081] The outer diameter of the engine compartment door cover 107 matches the inner diameter of the fixed ring chamber 201, and corresponding sealing elements are provided on the outer side of the engine compartment door cover 107, the upper end face of the unloading pipe port 209, and the outer surface of the sealing cover 214.

[0082] In this embodiment: the outer wall size of the sealing cover 214 is precisely matched with the inner wall size of the material discharge port 111, and its top arc shape is consistent with the circular trajectory of the inner cavity of the crushing chamber 102, ensuring that it can fit completely when sealing and preventing the leakage of cleaning water.

[0083] Meanwhile, the outer wall of the cabin door cover 107 matches the inner wall diameter of the fixed ring compartment 201 to ensure guidance and sealing during horizontal sliding;

[0084] The seals installed on the outer side of the engine compartment door cover 107, the upper end face of the unloading pipe port 209, and the outer surface of the sealing cover 214 can effectively prevent dust leakage or cleaning water seepage in both working and cleaning modes.

[0085] Please refer to this carefully. Figure 10 The cover 214 is formed with a tapered contraction at the drain outlet 215;

[0086] The drain outlet 215 and the water inlet pipe 216 extend vertically downward through the fixed platform 212. The fixed platform 212 has through holes for vertical sliding of the drain outlet 215 and the water inlet pipe 216.

[0087] In this embodiment: the tapered contraction portion formed at the drain outlet 215 of the sealing cover 214 can guide the residual cleaning water to quickly flow into the drain outlet 215 and avoid water accumulation;

[0088] The through hole on the fixed platform 212 provides vertical sliding space for the vertical parts of the drain outlet 215 and the water inlet pipe 216, so that when the second hydraulic cylinder 213 pushes the sealing cover 214 to move up and down, the drain outlet 215 and the water inlet pipe 216 can move along without interference, ensuring smooth operation.

[0089] Please refer to this carefully. Figure 6 Sliding sleeves 210 are symmetrically fixed on both sides of the outer wall of the discharge pipe 209, and two guide rods 211 are symmetrically installed on the lower surface of the machine base 101.
