[0004] Existing Chinese herbal medicine drying equipment has shortcomings in terms of waste gas treatment. During the drying process, the gas is often treated by using only bag filters or cyclone separators, which can only process large-diameter powders. Small-diameter powders and toxic and harmful gases cannot be further treated.

[0005] Therefore, a traditional Chinese medicine decoction piece drying device with a waste gas treatment structure is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a traditional Chinese medicine decoction piece drying device with a waste gas treatment structure to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a traditional Chinese medicine decoction piece drying device with a waste gas treatment structure, including a dryer and a dry-wet filtration mechanism. The top of the dryer is provided with a gas collection channel, and a first exhaust fan is connected to the side of the gas collection channel. A pressure chamber is installed at the outlet of the first exhaust fan, and a first air inlet pipe is fixedly connected to the outlet of the pressure chamber. The first air inlet pipe is connected to the dry-wet filtration mechanism, which includes a water filter tank and a filter barrel.

[0008] Preferably, a first air outlet pipe is installed at the top of the water filter tank, and a first valve is installed on the pipe body of the first air outlet pipe. When the dryer is running, and the first exhaust fan cooperates with the pressurization chamber to transport the exhaust gas into the interior of the water filter tank through the first air inlet pipe, so that the impurities in the exhaust gas dissolve in the water.

[0009] Preferably, the outlet of the first air outlet pipe is connected to the air inlet at the bottom of the filter barrel, and a second air outlet pipe is installed at the top of the filter barrel, with a second valve installed on the pipe body of the second air outlet pipe.

[0010] Preferably, a pressurized exhaust pipe is connected to the side of the second air outlet pipe away from the filter barrel, a drive housing is installed below the pressurized exhaust pipe, a drive motor is connected below the drive housing, and a collection box is installed at the air outlet end of the drive motor.

[0012] Preferably, the water filter tank has a filter chamber inside, and the first air inlet pipe has a third valve.

[0013] Preferably, the filter barrel has filter elements arranged at equal intervals inside. When exhaust gas enters the filter barrel through the water filter pipe along the first exhaust pipe, it is adsorbed and penetrated by the pressurized exhaust pipe.

[0014] Preferably, the dryer includes a drying chamber and a support base, the bottom of the drying chamber is equipped with the support base, and the four sides of the support base are all fixed with bolts.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] Compared with existing technologies, this Chinese herbal medicine drying device with a waste gas treatment structure employs a multi-stage filtration method combining dry and wet processes. First, it undergoes wet purification through a water filtration tank, using water to intercept particulate impurities, dissolve soluble gases, and induce chemical reactions in some gases, completing preliminary purification. Next, the waste gas enters a filter tank, where multiple sets of filter elements of different materials are arranged at equal intervals to specifically adsorb residual microparticles, unabsorbed gases, and odors, achieving deep purification. Simultaneously, a first exhaust fan, in conjunction with a pressurization chamber, provides power, and a third valve controls the air intake flow to ensure stable water filtration. The first and second valves respectively regulate the air output at each stage, driving a motor to power the pressurized exhaust pipe, ensuring the waste gas smoothly passes through each filtration stage. Finally, after passing through a collection box and meeting emission standards, the waste gas is discharged. This progressive process significantly improves waste gas purification efficiency and quality, effectively preventing environmental pollution from waste gas generated during the drying of Chinese herbal medicines.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] As attached Figures 1 to 4The illustrated drying device for Chinese herbal medicine slices with a waste gas treatment structure includes a dryer 1 and a wet and dry filtration mechanism 24. The dryer 1 has a gas collection channel 5 at its top, and a first exhaust fan 6 is connected to the side of the gas collection channel 5. A pressure chamber 7 is installed at the outlet of the first exhaust fan 6, and a first air inlet pipe 8 is fixedly connected to the outlet of the pressure chamber 7. The first air inlet pipe 8 is connected to an interference filtration mechanism. The wet and dry filtration mechanism 24 includes a water filter tank 9 and a filter barrel 12. The water filter tank 9 performs preliminary purification of the waste gas during waste gas treatment. Its interior has a filter chamber 21 containing water for contact with the waste gas; this water serves as the medium for wet purification. A third valve 22 is installed on the body of the first air inlet pipe 8. The third valve 22 can flexibly control the flow rate of the exhaust gas entering the water filter tank 9 according to actual working needs, so as to ensure the stable operation of the purification process. When the dryer 1 is running, the first exhaust fan 6, together with the pressurization chamber 7, transports the exhaust gas into the interior of the water filter tank 9 through the first air inlet pipe 8. Under the action of pressure, the exhaust gas passes through the water source in the filter chamber 21. In this process, the particulate impurities in the exhaust gas will be intercepted and precipitated by the water. Some gases that can dissolve in water will also dissolve in the water. At the same time, some gases that can react with water will also come into contact with the water and undergo chemical reactions, thereby achieving the purpose of preliminary purification of the exhaust gas.

[0025] In a preferred embodiment, a first exhaust pipe 10 is installed at the top of the water filter tank 9, and a first valve 11 is installed on the pipe body of the first exhaust pipe 10. When the dryer 1 is running, and the first exhaust fan 6 cooperates with the pressurization chamber 7 to transport the exhaust gas into the interior of the water filter tank 9 through the first intake pipe 8, so that the impurities in the exhaust gas dissolve in the water. The function of the first valve 11 is to control the flow rate of the exhaust gas after preliminary purification in the water filter tank 9 into the next treatment stage. After the exhaust gas has completed preliminary purification in the water filter tank 9, it is transported out through the first exhaust pipe 10.

[0026] In a preferred embodiment, the outlet of the first outlet pipe 10 is connected to the bottom inlet of the filter barrel 12, and a second outlet pipe 13 is installed at the top of the filter barrel 12. A second valve 14 is installed on the pipe body of the second outlet pipe 13. Filter elements 23 are arranged at equal intervals inside the filter barrel 12. When the exhaust gas enters the filter barrel 12 through the water filter pipe along the first outlet pipe 10, it is adsorbed by the pressurized exhaust pipe 15 and passes through the filter elements 23. The outlet of the first outlet pipe 10 is connected to the bottom inlet of the filter barrel 12. The exhaust gas, which has been pre-treated by the water filter tank 9, enters the filter barrel 12 for further purification. Filter elements 23 are arranged at equal intervals inside the filter barrel 12. These filter elements 23 use different filter materials and can specifically filter and adsorb different impurities in the exhaust gas. When the exhaust gas enters the filter barrel 12 through the first outlet pipe 10, it is subjected to the adsorption force of the pressurized exhaust pipe 15, forcing the exhaust gas to pass through the filter elements 23. Each time the exhaust gas passes through a filter element 23, the impurities in the exhaust gas are further purified. Whether it is residual tiny particles or gases and odors that have not been absorbed by water, they will be effectively adsorbed and filtered out by the filter element 23.

[0027] In a preferred embodiment, a pressurized exhaust pipe 15 is connected to the side of the second exhaust pipe 13 away from the filter barrel 12. A drive housing 16 is installed below the pressurized exhaust pipe 15, and a drive motor 17 is connected to the bottom of the drive housing 16. A collection box 19 is installed at the exhaust end of the drive motor 17. The second exhaust pipe 13 is installed at the top of the filter barrel 12. A second valve 14 is installed on the pipe body of the second exhaust pipe 13. The second valve 14 is used to control the output of the exhaust gas after deep purification by the filter barrel 12. The pressurized exhaust pipe 15 is connected to the side of the second exhaust pipe 13 away from the filter barrel 12. A drive housing 16 is installed below the pressurized exhaust pipe 15. The internal structure of the drive housing 16 provides power support for the pressurized exhaust pipe 15, and the drive motor 17 is connected to the bottom of the drive housing 16. The drive motor 17 is the power core of the pressurized exhaust pipe 15, providing power to the pressurized exhaust pipe 15 to ensure that the exhaust gas can be successfully purified in the filter barrel 12 and transported out.

[0028] In a preferred embodiment, the collection box 19 is equipped with support brackets 18 on all four sides, and the collection box 19 has a collection chamber 20 inside. The water filter tank 9 has a filter chamber 21 inside. The first air inlet pipe 8 is equipped with a third valve 22. The collection box 19 is installed at the air outlet of the drive motor 17. The support brackets 18 on all four sides of the collection box 19 provide stable support for the collection box 19, ensuring its stability during operation. The collection box 19 has a collection chamber 20 inside. The exhaust gas purified by the filter barrel 12 is finally transported into the collection chamber 20. The staff will strictly test the exhaust gas in the collection box 19. Only when all indicators of the exhaust gas meet the emission standards will it be discharged.

[0029] In a preferred embodiment, the dryer 1 includes a drying chamber 2 and a support base 3. The support base 3 is installed at the bottom of the drying chamber 2, and fixed brackets 4 are installed on all four sides of the support base 3 by bolts.

[0030] In this embodiment, the first exhaust fan 6 and the first valve 11 are commercially available devices known to those skilled in the art. They can be customized or selected according to actual needs. Here, we are only using them without making any structural or functional improvements, so we will not go into detail here.

[0031] The working process of this utility model is as follows: During the drying process of Chinese herbal medicine slices in the dryer 1, the moisture in the Chinese herbal medicine slices and the gas generated during drying are adsorbed into the first air inlet pipe 8 by the first exhaust fan 6 in conjunction with the booster fan in the pressurization chamber 7. Then, the moisture-laden exhaust gas is transported into the water filter tank 9 through the first air inlet pipe 8. Then, the pressurized exhaust pipe 15 is driven, and an adsorption force is generated in the first air outlet pipe 10. After the moisture-laden exhaust gas passes through the water source in the water filter tank 9, the particles and water-soluble gases in the exhaust gas are absorbed. Then, some reactive gases also react with water. After wet purification of the moisture-laden waste gas, the waste gas is collected in the first outlet pipe 10 and enters the interior of the filter barrel 12. The waste gas then comes into contact with the filter element 23 inside the filter barrel 12. The filter barrel 12 is equipped with multiple layers of filter elements 23. Each time the waste gas passes through a layer of filter element 23, the impurities in the waste gas are purified. After the waste gas passes through the filter barrel 12, the gas and odor in the waste gas are adsorbed by the filter element 23. Then, the adsorbed waste gas is transported into the interior of the collection box 19. After the waste gas in the collection box 19 is detected, it is discharged, thus completing the treatment of the waste gas during the drying process of Chinese herbal medicine pieces.
