Description

Technical Field

[0001] This invention relates to the technical field of water dust removal, and in particular to a water dust removal device suitable for a traditional Chinese medicine frying machine. Background Technology

[0002] Stir-frying Chinese medicinal herbs is a crucial traditional process in traditional Chinese medicine processing. High-temperature heating helps reduce toxicity, enhance efficacy, alter medicinal properties, and facilitate pulverization. However, this process inevitably generates large amounts of high-temperature fumes. These fumes contain dust, water vapor, and a pungent odor; direct emission would severely pollute the workshop environment and harm the health of operators. Currently, the industry typically uses water-based dust removal devices for preliminary purification of the stir-frying fumes, utilizing the adsorption and dissolving properties of water to remove dust and some soluble gases.

[0003] In existing water dust removal processes, such as Chinese Patent Publication No. CN217773637U, a water dust removal device suitable for a Chinese herbal medicine frying machine is disclosed. The device includes a Chinese herbal medicine frying machine, one end of which is provided with a dust outlet. It also includes a water dust removal device, with a dust collection hood fixedly installed above the dust outlet. The dust inlet of the water dust removal device is fixedly connected to the upper part of the dust collection hood through a dust inlet pipe. The gas outlet of the water dust removal device is connected to the outside through a gas suction and discharge pipe.

[0004] The aforementioned prior art mainly uses water filtration devices to remove impurities from flue gas. However, the aforementioned prior art does not take into account that many Chinese medicinal herbs are rich in oils or resins, for example: When seed-based medicinal materials (such as bitter almonds, jujube seeds, and cassia seeds) are stir-fried at high temperatures, the plant oils inside their cells evaporate due to heat or escape with water vapor and enter the smoke. When resins and animal-derived medicinal materials (such as frankincense, myrrh, and asafoetida) are heated, their resinous components melt directly into a viscous state and evaporate with the hot airflow.

[0005] When these oily fumes are drawn into a traditional water dust collector, they quickly undergo a phase change and condense upon contact with cold water, forming two highly destructive forms of matter in the water and inside the equipment: one is liquid oil floating on the water surface, and the other is tar-like gum oil suspended or adhering to the inner wall of the equipment. If these oily substances cannot be separated and discharged in a timely and effective manner, it will cause serious blockage of pipes and equipment, destroying the water washing and purification effect, and making subsequent equipment cleaning and maintenance extremely difficult.

[0006] Therefore, there is still room for improvement in the aforementioned existing technologies. Summary of the Invention

[0007] In order to deal with the oily fumes generated during the stir-frying of Chinese medicinal herbs and to remove liquid oils and solid gum oils as quickly as possible, this application provides a water dust removal device suitable for stir-frying machines for Chinese medicinal herbs.

[0008] The water dust removal device for a traditional Chinese medicine frying machine provided in this application adopts the following technical solution: A water-based dust removal device suitable for a traditional Chinese medicine frying machine includes the frying machine, which is connected to a first purification cylinder via a connecting module, the first purification cylinder being mounted on a base; a floating oil suction module disposed on the outer periphery of the end of the connecting module, which absorbs and discharges liquid oil; a lifting dust removal module disposed in the first purification cylinder, which filters and discharges suspended impurities during its up-and-down movement; a dirt suction module disposed on the base; and a second purification cylinder disposed on the base, which is connected to the first purification cylinder via a series pipe.

[0009] Preferably, the communication module includes a communication pipe, one end of which is connected to the roasting machine and the other end to the first purification cylinder; and a floating pipe, which is slidably disposed at the lower end of the first purification cylinder, located inside the first purification cylinder. Since the floating pipe is fixedly installed with a floating plate, and the floating plate floats on the water surface, when the water level drops, the floating plate descends accordingly, causing the floating pipe to descend as well, thus ensuring that the depth to which the floating pipe is inserted underwater remains constant. This ensures that the depth to which the flue gas enters the water remains uniform, effectively maintaining stable dust removal efficiency.

[0010] Preferably, the floating oil suction module includes a floating disc, which is sleeved on the outer periphery of the floating pipe. A hollow groove is formed inside the floating disc, and an oil collection trough is provided in the lower center of the floating disc. An oil suction pipe is disposed in the hollow groove and communicates with the sludge suction module. An oil suction head is installed at the lower end of the oil suction pipe. A connecting hole is formed at the lower end of the hollow groove, connecting the hollow groove to the oil collection trough. The oil suction head passes through the connecting hole and extends into the oil collection trough. A baffle is installed on the outer periphery of the oil collection trough, located below the oil suction head, and the baffle restricts the suction force of the oil suction head. The system includes a trigger assembly mounted on a floating disc, and a filter baffle installed inside the first purification cylinder. The filter baffle is located below the floating disc and has a clearance hole in the middle. The lower end of the floating tube passes through the clearance hole. The filter baffle performs a filtering function. Because it is located between the lower ends of the floating disc and the floating tube, the flue gas enters the clean water below the filter baffle. At this time, liquid grease can pass through the filter baffle and float to the surface, but other impurities are intercepted below the filter baffle, thus preventing other impurities from interfering with the collection of liquid grease.

[0011] Preferably, the density of the floating disk is less than that of water but greater than that of oil, so that the floating disk can float on the water surface.

[0012] Preferably, the triggering component includes a floating element that slides up and down in the oil collection tank; and a sensor switch installed in the hollow tank, the position of which corresponds to that of the floating element, and the sensor switch being electrically connected to the suction module.

[0013] Preferably, the density of the floating component is less than that of the oil, so that the floating component can float on the oil surface.

[0014] Preferably, the lifting dust removal module includes a motor, which is installed in the base through an insulating shell, and the output end of the motor is connected to a threaded rod; a lifting frame, which is slidably installed inside the first purification cylinder, and the middle part of the lifting frame is threadedly engaged with the threaded rod; a flip-down door, which is rotatably installed in a clear hole opened on the lifting frame, and a first spring is connected between the flip-down door and the clear hole, the first spring playing a reset role, and a filter hole is opened on the flip-down door, in which a blocking element is slidably installed; and a discharge mechanism, which is located at the bottom of the first purification cylinder.

[0015] Preferably, the unobstructed hole is a stepped hole, with the upper diameter being smaller than the lower diameter; the filter hole is a stepped hole, with the upper diameter being larger than the lower diameter.

[0016] Preferably, the discharge mechanism includes a discharge pipe installed at the bottom of the first purification cylinder, the discharge pipe being connected to the first purification cylinder and the discharge pipe being connected to the suction module; a tilting component rotatably disposed at the bottom of the first purification cylinder; a discharge valve disposed in the discharge pipe; and a pressing component installed at the lower end of the lifting frame.

[0017] Preferably, the turning component consists of an inclined section and a straight section, with the straight section corresponding to the position of the pressing component.

[0018] In summary, the beneficial technical effects of this application are as follows: This invention discloses a water-based dust removal device suitable for a traditional Chinese medicine (TCM) frying machine. It achieves targeted separation and automatic discharge of the unique "liquid oil" and "tar-like gum oil" found in the fumes from TCM frying. First, for the liquid oil floating on the water surface, the density difference forces the oil into the oil collection tank. Combined with a liquid level trigger component, it achieves automated pure oil extraction by "extraction when full." The flow-limiting design of the bottom baffle effectively prevents water from mixing in, ensuring the purity of the discharged oil. Second, for the suspended and adhered gum oil, the reciprocating motion of the lifting frame, through the hydrodynamic linkage between the downward-opening door and the blocking component, precisely intercepts and squeezes the gum oil downwards during the downward pressure closing phase. Combined with the mechanical linkage between the bottom pressing component and the material-turning component, it achieves automatic scraping and forced extraction of high-viscosity gum oil. This dual oil discharge mechanism significantly improves the system's purification efficiency and continuous operating life. Attached Figure Description

[0021] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0022] This application discloses a water dust removal device suitable for a Chinese herbal medicine frying machine. It can effectively prevent blockage by automatically identifying and removing liquid oils and collecting and automatically discharging tar-like gum oils.

[0023] Reference Figure 1 , Figure 2As shown, a water-based dust removal device suitable for a traditional Chinese medicine frying machine includes a frying machine 1, which is connected to a first purification cylinder 3 via a connecting module 2. The first purification cylinder 3 is mounted on a base 4. A floating oil suction module 5 is mounted on the outer periphery of the end of the connecting module 2, which absorbs and discharges liquid oil. A lifting dust removal module 6 is mounted in the first purification cylinder 3, which filters and discharges suspended impurities during its up-and-down movement. A dirt suction module 7 is mounted on the base 4. A second purification cylinder 8 is mounted on the base 4 and is connected to the first purification cylinder 3 via a series pipe 9.

[0024] In actual operation, the fumes generated during the stir-frying of Chinese medicine in the stir-frying machine 1 enter the first purification cylinder 3 through the connecting module 2. The first purification cylinder 3 contains clean water, and the depth to which the connecting module 2 is inserted into the clean water is always kept constant. The fumes are directly in contact with the clean water for purification. During this process, the liquid grease gradually increases. Since the density of oil is less than that of water, it gradually floats to the surface of the water. The floating oil suction module 5 guides and gathers the liquid grease and senses its quantity. When the quantity reaches a certain level, it is sucked out and discharged. At the same time, the lifting dust removal module 6 is always in a state of up-and-down reciprocating motion throughout the entire operation. When the lifting dust removal module 6 moves downward, it performs filtration and collection work, collecting and discharging the colloidal grease suspended in the water. Afterward, the fumes enter the second purification cylinder 8 through the series pipe 9 for further purification and discharge (multiple purification cylinders can be connected in series for multi-level purification depending on the needs). This application, by specifically treating the grease, discharges liquid grease and colloidal grease in a timely manner, reducing the risk of equipment blockage and lowering maintenance costs.

[0025] Reference Figure 1 , Figure 3 As shown, the communication module 2 includes a communication pipe 21, one end of which is connected to the roasting machine 1, and the other end of which is connected to the first purification cylinder 3; and a floating pipe 22, which is slidably disposed at the lower end of the first purification cylinder 3. The floating pipe 22 is located inside the first purification cylinder 3. Since the floating pipe 22 is fixedly installed with the floating disk 51, and the floating disk 51 floats on the water surface, when the water level drops, the floating disk 51 descends accordingly, causing the floating pipe 22 to descend as well, thereby ensuring that the depth to which the floating pipe 22 is inserted into the water remains constant. This ensures that the depth to which the flue gas enters the water remains uniform, effectively maintaining the stability of the dust removal efficiency.

[0026] In actual operation, the fumes from frying medicinal herbs enter the water inside the first purification cylinder 3 through the connecting pipe 21 and the floating pipe 22. The floating pipe 22 automatically moves up and down with the water level.

[0027] Reference Figure 3 , Figure 4As shown, in order to collect and discharge liquid grease floating on the water surface, this application provides a floating oil suction module 5. The floating oil suction module 5 includes a floating disk 51, which is sleeved on the outer periphery of the floating pipe 22. A hollow groove 511 is opened inside the floating disk 51, and an oil collection groove 512 is provided in the middle of the lower end of the floating disk 51; an oil suction pipe 52, which is disposed in the hollow groove 511 and is connected to the sludge suction module 7; an oil suction head 53, which is installed at the lower end of the oil suction pipe 52. A connecting hole 513 is opened at the lower end of the hollow groove 511, which connects the hollow groove 511 and the oil collection groove 512. The oil suction head 53 passes through the connecting hole 513 and extends into the oil collection groove 512; and a baffle 54, which is installed on the outer periphery of the oil collection groove 512. The baffle 54 is located below the oil suction head 53, which restricts the suction direction of the oil suction head 53 and prevents water from being absorbed and discharged. The trigger component 55 is set on the floating plate 51. The filter baffle 56 is installed inside the first purification cylinder 3 and is located below the floating plate 51. The filter baffle 56 has a clearance hole 561 in the middle, through which the lower end of the floating tube 22 passes. The filter baffle 56 plays a filtering role. Since it is located between the lower ends of the floating plate 51 and the floating tube 22, when the flue gas enters the clean water, it is located below the filter baffle 56. At this time, the liquid grease can pass through the filter baffle 56 and float up, but other impurities are intercepted below the filter baffle 56, thereby preventing other impurities from interfering with the collection of liquid grease.

[0028] Reference Figure 3 As shown, the density of the floating disk 51 is less than that of water but greater than that of oil, which allows the floating disk 51 to float on the water surface.

[0029] Reference Figure 5 As shown, the triggering component 55 includes a floating element 551, which is slidably disposed in the oil collection tank 512; and a sensor switch 552, which is installed in the hollow slot 511. The sensor switch 552 is positioned corresponding to the floating element 551 and is electrically connected to the suction module 7.

[0030] Reference Figure 5 As shown, the density of the floating component 551 is less than that of oil, which allows the floating component 551 to float on the oil surface.

[0031] In actual liquid grease removal, the grease floats to the surface and comes into contact with the floating disk 51. Since the density of the floating disk 51 is greater than that of the oil (and the amount of oil floating is not too much, and the floating disk 51 itself also has a certain weight), the oil cannot lift the floating disk 51. The floating disk 51 is always in contact with the water surface. Therefore, the floating grease gathers in the only gap between the floating disk 51 and the water surface, namely the oil accumulation tank 512. As more and more grease accumulates, the floating component 551 is lifted upward by the grease and squeezes the induction switch 552. The induction switch 552 triggers the start of the suction module 7. The suction module 7 generates suction, and the oil suction head 53 absorbs the grease and transfers it into the suction module 7 through the oil suction pipe 52.

[0032] When the oil suction head 53 is absorbing oil, the baffle 54 is located directly below the oil suction head 53, forcing the oil suction head 53 to absorb the grease from the side of the oil collection tank 512, thus avoiding the absorption of water.

[0033] Reference Figure 3 , Figure 6 , Figure 7 As shown, most of the gelatinous grease is suspended in water. In order to collect and discharge it, this application provides a lifting dust removal module 6. The lifting dust removal module 6 includes a motor 61, which is installed in the base 4 through an insulating shell 62. The output end of the motor 61 is connected to a threaded rod 63; a lifting frame 64, which is slidably installed inside the first purification cylinder 3. The middle part of the lifting frame 64 is threadedly engaged with the threaded rod 63; a flip-down door 65, which is rotatably installed in a clear hole 641 opened on the lifting frame 64. A first spring is connected between the flip-down door 65 and the clear hole 641. The first spring plays a reset role. A filter hole 651 is opened on the flip-down door 65. A blocking element 66 is slidably installed in the filter hole 651; and a discharge mechanism 67, which is installed at the bottom of the first purification cylinder 3.

[0034] Reference Figure 6 As shown, the unobstructed hole 641 is a stepped hole, with the upper diameter of the unobstructed hole 641 being smaller than the lower diameter; the filter hole 651 is a stepped hole, with the upper diameter of the filter hole 651 being larger than the lower diameter.

[0035] In actual collection of suspended colloidal grease, motor 61 drives threaded rod 63 to rotate. Under the action of the thread, lifting frame 64 moves upward. At this time, under the action of pressure (lifting frame 64 moves upward, water pressure is downward), the flip door 65 flips downward and opens, thus making the unobstructed hole 641 unobstructed, allowing water, air, impurities, etc. to pass through smoothly. When the lifting frame 64 moves to the top, motor 61 drives threaded rod 63 to rotate in the opposite direction, causing lifting frame 64 to move downward. When lifting frame 64 moves downward, flip door 65 flips upward and closes under the action of the first spring and pressure (lifting frame 64 moves downward, water pressure is upward). The blocking part 66 moves upward under the action of pressure, causing filter hole 651 to open. Filter hole 651 does not allow suspended colloidal grease to pass through, thus squeezing it downward and collecting it.

[0036] Reference Figure 7 As shown, this application is provided with a discharge mechanism 67 for discharging materials. The discharge mechanism 67 includes a discharge pipe 671, which is installed at the bottom of the first purification cylinder 3 and is connected to the first purification cylinder 3 and the suction module 7; a turning component 672, which is rotatably installed at the bottom of the first purification cylinder 3; a discharge valve 673, which is installed in the discharge pipe 671; and a pressing component 674, which is installed at the lower end of the lifting frame 64.

[0037] Reference Figure 8 As shown, the flipping component 672 is composed of an inclined section 6721 and a straight section 6722, and the straight section 6722 corresponds to the position of the pressing component 674.

[0038] During actual material discharge, the lifting frame 64 moves downward so that the pressing part 674 and the flipping part 672 come into contact. The pressing part 674 presses the straight section 6722, causing the flipping part 672 to flip. The inclined section 6721 pushes the grease towards the center, the discharge valve 673 opens, and the suction module 7 absorbs the grease into its own interior.

[0039] The implementation principle of this embodiment is as follows: Step 1: The medicinal materials are stir-fried in stir-frying machine 1; Step 2: The flue gas is discharged into the water through the connecting pipe 21 and the floating pipe 22. The floating plate 51 rises and falls adaptively with the water level, driving the floating pipe 22 to maintain a constant insertion depth and keep the basic dust removal efficiency stable. Step 3: The flue gas rises and passes through the filter baffle 56. Large particles of dust and other impurities are directly intercepted below the filter baffle 56, while the less dense liquid grease passes through the filter baffle 56 and continues to float to the water surface. Step 4: The floating liquid oil is blocked by the floating plate 51 and flows into the oil collection tank 512 below it; Step 5: As the oil layer thickens, the floating part 551 is lifted up, squeezing and triggering the induction switch 552. Under the physical obstruction of the baffle 54 directly below, the oil suction head 53 is forced to only suck from the side of the oil accumulation tank, thereby accurately sucking up pure oil and discharging it through the oil suction pipe 52, effectively preventing the intake of water. Step 6: The lifting frame 64 moves up and down repeatedly; when moving up, the water pressure pushes the flip door 65 down to allow impurities to pass through; when moving down, the water pressure and spring cause the flip door to close, and at the same time pushes the blockage part 66 up to open the filter hole 651, using the hole diameter to intercept the colloid and grease in the water and squeeze it down to peel it off. Step 7: When the lifting frame 64 is lowered to the bottom, the pressing part 674 at the bottom touches the straight section 6722 of the flipping part 672 to flip it over. The inclined section 6721 pushes the peeled gum oil towards the central discharge port. At the same time, the discharge valve 673 is opened, and the suction module 7 extracts the gum oil. Step 8: After removing the liquid oil and gum oil, the gas is cut into the second purification cylinder 8 through the series pipe 9 for final deep water washing and purification, and then discharged after meeting the standards.

[0040] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
