Description

Technical Field

[0001] The utility model belongs to the field of traditional Chinese medicine wastewater treatment, and specifically relates to a traditional Chinese medicine extraction wastewater treatment device. Background Art

[0002] According to the processing technology, Chinese medicine is divided into Chinese patent medicine and Chinese medicinal materials. The Chinese medicine preparation industry has a wide variety of products, and the production process is diverse and complex. In the pharmaceutical production process, the input of raw materials is large, the output ratio is small, and most of its substances eventually become waste, resulting in serious pollution problems. Chinese medicine pharmaceutical wastewater is not only a large category of pharmaceutical wastewater: it has the characteristics of high organic concentration, complex composition, and difficulty in treatment, but also has high chromaticity, large volatility, light suspended matter, and many organic substances that are difficult to precipitate. At present, the production of Chinese patent medicines mostly adopts the water-soluble method. The production process of the water-soluble method includes three steps: washing medicine, boiling and preparation. Therefore, the wastewater mainly comes from the washing water of raw materials, the residual night of the original medicine decoction, and the washing water on the ground surface. Because some Chinese patent medicines contain toxins or even highly toxic substances before being produced by the water-soluble method, most of the toxins they contain enter the wastewater after being produced by the water-soluble method, so some wastewater is toxic. In the prior art, precipitation, adsorption and other methods are only used to treat larger particles and suspended matter, and the filtration efficiency of organic matter is low. There is a lack of active interference in the sedimentation and filtration process to promote its filtration efficiency. Simple transportation between different tanks cannot ensure sufficient contact between the waste liquid and the treatment equipment. There is a lack of refined resource utilization. In addition, there is no good neutralization method for harmful ions. Therefore, there is a need for a wastewater treatment device that actively intervenes in the filtration process of traditional Chinese medicine extraction wastewater during the filtration process, and quickly captures, adsorbs or settles small particles and large molecular organic impurities that are difficult to precipitate.

[0018] like Figure 1 , Figure 2 As shown, a Chinese medicine extraction wastewater treatment device includes a stirring and filtering mechanism 4, wherein the stirring and filtering mechanism 4 is provided with a cylindrical shell 401, and a stirring inner cavity 410 is provided in the cylindrical shell 401. The cylindrical shell 401 is connected to the first storage tank 2 through a drainage pipe 101, and openings are provided at both ends of the drainage pipe 101 to communicate with the stirring inner cavity 410 of the stirring and filtering mechanism 4. The other end of the stirring and filtering mechanism 4 is connected to the second storage tank 3 through the drainage pipe 101, and the first storage tank 2 is connected to the first sedimentation tank 1 through a pipe with a pump 102, and the second storage tank 3 is connected to the second sedimentation tank 7 through a pipe with a pump 102. The stirring and filtering mechanism 4 is also connected to the water outlet tank 6 through a pipe with a valve 429, and the pump 102 is a high-pressure water pump. The first storage tank 2 and the second storage tank 3 are both connected to the steam supply device through a pipe with a steam control valve 10.

[0019] The stirring cavity 410 is provided with a stirring mechanism, and the stirring mechanism includes a stirring main shaft 420, and the stirring main shaft 420 is rotatably connected to the cylindrical shell 401. The stirring main shaft 420 is also connected to the stirring motor 5 shaft. The stirring mechanism is also provided with a rotating electrophoresis network 406, and the rotating electrophoresis network 406 is sleeved on the rotating main shaft. The rotating electrophoresis network 406 is provided with a rotary electrophoresis filter 430. The stirring cavity 410 is divided into a first stirring cavity 8 and a second stirring cavity 9 by a partition plate 413. The first stirring cavity 8 and the second stirring cavity 9 are both provided with a spiral guide plate 402 along the inner edge of the cylindrical shell 401 of the shell.

[0020] The implementation method is as follows: for Chinese medicine extraction wastewater of different properties (mainly the case where the large particles are quite different and blockages are easily generated after mixing), they are respectively flowed into the first sedimentation tank 1 and the second sedimentation tank 7 for preliminary sedimentation, and conventional reagents such as lime, licorice liquid, activated carbon, etc. are respectively added for pre-treatment such as large particle adsorption and precipitation, pH value adjustment, etc., and then the Chinese medicine extraction wastewater is pumped into the first storage tank 2 and the second storage tank 3 through the drainage pipe 101 by the water pump 102, and the mixing gas is injected into the first storage tank 2 and the second storage tank 3 under the control of the steam control valve 10. After further pre-treatment, the waste liquid containing harmful substances that need to be fully mixed and electrophoretically adsorbed is further pumped from the first storage tank 2 and the second storage tank 3 into the stirring and filtering mechanism 4. The electrode 403 works to charge the electrode plate 431, so that the toxic ions, particles and macromolecules in the disturbed waste liquid in the stirring cavity 410 carry charges. Under the stirring of the rotating electrophoresis net 406 of the stirring mechanism and the action of the guide plate 402, the waste liquid forms a spiral flow in the stirring cavity and is in full contact with the rotating electrophoresis net 406. The toxic ions, particles and macromolecules are adsorbed on the rotating electrophoresis net 406.

[0021] like Figure 2 , 3As shown in , 5, a connecting plate 408 is arranged between the first stirring chamber 8 and the second stirring chamber 9, the connecting plates 408 are arranged in pairs and surround a connecting chamber 404, the partition plate 413 is arranged in the connecting chamber 404, the AC roller assembly 407 includes a rotating extrusion roller 412, the partition plate 413 is rotatably connected to the rotating extrusion roller 412, the partition plate 413 is also tightly connected to the fixed extrusion roller 419, the rotating extrusion roller 412 and the fixed extrusion roller 419 are arranged in a plurality of groups along the partition plate 413 at intervals, the rotating extrusion roller 412 includes a main roller body, the main roller body is provided with a filter mounting hole, the filter mounting holes are arranged in a plurality of groups along the circumference of the main roller body, an extrusion filter 414 is penetrated in the filter mounting hole, the extrusion filter 414 is alternately arranged inside and outside the main roller body through the filter mounting hole, and an extrusion roller through hole 411 is arranged in the arc section of the main roller body wrapped by the extrusion filter 414. The extrusion filter 414 is provided with a filter mounting hole, the filter mounting hole corresponding to the side of the extrusion filter 414 close to the outer edge of the main roller body has a smaller aperture, and the filter mounting hole corresponding to the side of the extrusion filter 414 away from the outer edge of the main roller body has a larger aperture, and single-layer filter screens 416 are laid at both ends of the filter mounting hole, and a partition hinge 417 is provided at the end with a larger aperture of the filter mounting hole, and a flow partition 418 is rotatably provided on the partition hinge 417, and the flow partition 418 is in a curved arc shape, and the inner side of the arc faces the end with a smaller aperture of the filter mounting hole.

[0022] The implementation method is as follows: when the first stirring chamber 8 and the second stirring chamber 9 are filled with liquid, the liquid first enters from the conical hole 415 and is temporarily stored in the gap between the extrusion filter 414 and the main roller body. At this time, the rotating extrusion roller 412 rotates. When the extrusion filter 414 rotates to fit with the fixed extrusion roller 419, the extrusion filter 414 is pushed radially inward of the main roller body, and the liquid temporarily stored in the aforementioned gap enters the main roller body through the guide roller through hole on the main roller body. In this way, the liquid in the first stirring chamber 8 and the liquid in the second stirring chamber 9 are continuously mixed through the AC roller assembly 407.

[0023] In order to ensure that as much liquid as possible is pressed into the main roller body for mixing, a one-way flow hole is provided in the extrusion filter 414, that is, Figure 5 As shown in the figure, when liquid enters the above-mentioned gap, the flow partition 418 swings downward around the partition hinge 417 to allow the liquid to pass through; when the liquid flows out of the gap, the flow partition 418 swings upward around the partition hinge 417 to prevent the liquid from flowing back.

[0024] like Figure 2 and Figure 4As shown, a deflection ring 421 is sleeved on the stirring main shaft 420, and a plurality of the deflection rings 421 are arranged axially along the stirring main shaft 420. The deflection ring 421 is fixedly connected to the rotating electrophoresis net 406, and a columnar flushing channel 422 is formed between the deflection ring 421 and the stirring main shaft 420. The rotating electrophoresis net 406 includes a swing bracket 426, and the swing bracket 426 is rotatably connected to the stirring main shaft 420. A pulley mounting frame 424 is provided on the swing bracket 426, and the pulley mounting frame 424 is arranged in pairs, and the pulley mounting frame 424 is rotatably connected to a rotating pulley 427.

Figure 2 The electrophoretic filter 430 in the second stirring chamber 9 on the right side is in a spiral distribution state, which can make the stirring and contact more complete. At the same time, the rotary pulley 427 rotates, driving the electrophoretic filter 430 to rotate. The particles in the waste liquid are adsorbed on the electrophoretic filter 430 and then enter the area of ​​the flushing channel 422 along the electrophoretic filter 430. The flushing channel 422 has an independent flow along the circumference of the stirring main shaft 420. The independent flow flushes away the particles and other waste materials on the electrophoretic filter 430. At the same time, the water quality detection device in the flushing channel 422 detects the concentration of the particles after flushing until the concentration of the particles and other waste materials is reduced to meet the standard.

[0026] In order to ensure the controllability of the rotation angle of the rotating electrophoresis network 406, an embodiment is as follows:

[0027] The stirring main shaft 420 is sleeved with a deflection ring 421, and a plurality of the deflection rings 421 are arranged along the axial direction of the stirring main shaft 420. The deflection ring 421 is fixedly connected to the rotating electrophoresis network 406.

The fixed gear 423 can be processed with missing teeth or filled teeth to control the position of the auxiliary gear 425, thereby controlling the spiral arrangement state of several rotating electrophoretic nets 406.
