Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology for traditional Chinese medicine, specifically a wastewater treatment and recycling device for the processing of traditional Chinese medicine. Background Technology

[0002] Traditional Chinese medicine (TCM) refers to natural medicines and their processed substitutes that are guided by TCM theory, possess a unique theoretical system and application forms, and are used for the prevention and treatment of diseases, as well as for rehabilitation and health maintenance. It mainly includes plant-based medicines, animal-based medicines, and mineral-based medicines. The production and extraction process of TCM generates a large amount of wastewater, primarily including wastewater from washing medicinal materials, extraction processes, equipment cleaning, preparation processes, and floor washing. This wastewater generally requires pretreatment, biochemical treatment, and advanced treatment before it can be reused. For example, a Chinese patent with authorization announcement number CN211078728U discloses a high-efficiency TCM processing wastewater treatment and recycling device, including a working box. A water injection tank is welded to the top of the left side wall of the working box. The inner cavity of the water injection tank is equipped with an inclined metal filter screen. An openable and closable inlet is located on the left side wall of the water injection tank near the metal filter screen. A rotating shaft is connected to the bottom of a rotary motor, and evenly distributed stirring blades are welded to both sides of the bottom of the rotating shaft. The inner cavity of the working box is equipped with a transverse purification layer.

[0003] The technical solution in the aforementioned patent document purifies wastewater through multi-step treatment, but it still has the following drawbacks: the wastewater from traditional Chinese medicine treatment has a pH deviation during the treatment process. Although existing technologies neutralize the wastewater by adding acidic or alkaline agents during chemical treatment, the treatment containers are all in the same container, which can easily affect the subsequent acid-base treatment of the wastewater. In addition, the wastewater contains a large amount of fine medicinal residue and other impurities. Existing technologies also require cleaning the treatment containers after completing the chemical treatment of the wastewater to ensure subsequent wastewater treatment, which not only increases the burden on staff but also reduces the efficiency of wastewater treatment. Summary of the Invention

[0004] To overcome the aforementioned deficiencies of the prior art, this invention provides a wastewater treatment and recycling device for traditional Chinese medicine processing. By setting up two containers corresponding to different pH levels of wastewater, after the pH sensor in the regulating tank completes its measurement of the wastewater, it drives the switching mechanism based on the wastewater's pH level. This allows wastewater with different pH levels to enter the corresponding containers, avoiding contamination of subsequent wastewater treatment. During rotation and adjustment, the switching mechanism synchronizes the adjustment of the filter screen through the raising and lowering of the aeration components. When the aeration components leave, the filter screen collects and lifts impurities from the wastewater, automatically removing medicinal residues and other impurities in conjunction with the cleaning components. This reduces manual labor and improves wastewater treatment efficiency, thus solving the problems mentioned in the background art.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. By setting up two containers corresponding to different pH levels of wastewater, after the pH sensor in the equalization tank completes the measurement of the wastewater, it drives the switching mechanism to operate according to the pH level of the wastewater, thereby enabling wastewater with different pH levels to enter the corresponding containers and avoiding pollution to subsequent wastewater treatment.

[0027] 2. When the switching mechanism rotates and adjusts, it achieves synchronous adjustment of the filter screen by raising and lowering the aeration element. Thus, when the aeration element leaves, the filter screen can collect and lift impurities in the sewage. In conjunction with the cleaning component, it can automatically remove impurities such as drug residue, reduce manual workload, and improve sewage treatment efficiency.

[0028] 3. When the rotation of the switching mechanism drives the aeration element to move and adjust, the cooperation between the external toothed ring and the arc-shaped toothed plate in the aeration element will synchronously drive the aeration pipe in the aeration element to rotate. During the rotation of the aeration pipe, the aeration holes on it come into contact with the cleaning brush. Thus, the aeration holes achieve self-cleaning under the cooperation of gas outflow and cleaning brush, avoiding blockage by drug residue and other impurities, and extending their service life.

[0029] 4. The dregs and other impurities cleaned by the slag-liquid separation mechanism are guided into the collection chamber by the action of the inclined plate. The collection chamber can be cleaned by removing the baffle.

[0030] 5. When wastewater enters the chemical treatment unit, the corresponding acid and alkali agents and coagulants are added simultaneously. Together with the gas discharged from the aeration unit, it can not only accelerate the neutralization of the acidity and alkalinity of the wastewater, but also achieve rapid stratification of impurities such as drug residues in the wastewater. Larger impurities coagulate and settle, while fine impurities float on the water surface under the protection of air bubbles, thereby improving the efficiency of wastewater impurity removal and further improving the efficiency of wastewater treatment.

[0031] 6. A biological treatment unit is arranged below the chemical treatment unit to further treat the wastewater that has undergone chemical treatment and impurity removal. Then, in conjunction with the main body of the water pump, the purified water can be refilled into a water tank for storage, which is convenient for subsequent use, thereby realizing the treatment and recycling of wastewater.

[0055] Please see Figure 3 and Figures 15-16 In this embodiment of the invention, the equipment box 1 includes a box body 11, and the interior of the box body 11 is provided with a vertical plate 12 for dividing the working space.

The collection hopper 21 is bolted to the upper partition plate 13. Both the pH sensor body 22 and the water level sensor body 23 are mounted on the rear inner wall of the collection hopper 21. A hole is formed in the left side shell wall of the collection hopper 21, through which a pipe connecting to the external herbal wastewater is installed. The pH sensor body 22 detects the pH of the herbal wastewater in the collection hopper 21 and transmits the result to the controller body 9. The water level sensor body 23 monitors the water level of the herbal wastewater in the collection hopper 21. When the herbal wastewater in the collection hopper 21 reaches the level indicated by the water level sensor body 23, the controller body 9 discharges the herbal wastewater from the collection hopper 21, thus controlling the amount of herbal wastewater discharged and ensuring the quality of herbal wastewater treatment.

[0058] A circular hole is provided at the center of the upper partition 13, and the drain port of the collection hopper 21 extends out of the circular hole and is equipped with a rotating connector. The air pump body 6 is mounted on the upper partition 13.

A placement groove is provided on the front inner wall of the arc-shaped through groove, and an arc-shaped toothed plate 55 is disposed in the placement groove.

[0066] The guide component 52 includes an L-shaped tube mounted on the rotating connector. A bidirectional conical cylinder is installed at the front end of the L-shaped tube, and a control valve is also installed on the L-shaped tube. The bottom diameter of the bidirectional conical cylinder is larger than the top diameter.

[0069] The rear end of the protruding rod is slidably connected to the guide groove. Below the collar, there is an external toothed ring 532 located on the outer shell wall of the aeration pipe 531. The external toothed ring 532 meshes with the arc-shaped toothed plate 55. The length of the arc-shaped toothed plate 55 is shorter than the smooth part of the guide groove, so that the disengagement and engagement between the external toothed ring 532 and the arc-shaped toothed plate 55 can be stably realized when the aeration element 53 moves in a circular motion.

[0072] The cleaning brush 54 includes a support arm and an arc-shaped brush plate. The support arm is fixedly connected to the top of the arc-shaped brush plate, and the top end of the support arm is fixedly connected to the bottom shell wall of the upper partition 13 by bolts.

[0073] Inclined plate 16 is located behind the two slag-liquid separation components 31, and is arranged with the left side higher than the right side. This allows the cleaned dregs and other impurities to enter the collection chamber on their own. The controller body 9 is mounted on the upper partition plate 14.

[0074] The working principle of this invention is as follows: When treating wastewater from traditional Chinese medicine (TCM), the wastewater from the laboratory, after initial filtration by a water tank screen, enters the equalization tank 2 through a pipeline. Since the water tank screen can only filter out large medicinal residues and other impurities in the wastewater, a large amount of fine medicinal residues and other impurities still remain after the wastewater enters the equalization tank 2 through the pipeline.

[0075] The wastewater containing traditional Chinese medicine entering the equalization tank 2 is temporarily stored in the collection hopper 21. The pH sensor 22 and the water level sensor 23 in the collection hopper 21 detect the pH and water level of the wastewater, respectively. The pH sensor 22 and the water level sensor 23 transmit the detected information to the controller 9. The control program in the controller 9 compares the received information according to the pre-set parameters.

[0076] At this time, the controller body 9 controls the operation of the multi-section electric push rod 321 in the air pump body 6 and the cleaning assembly 32. The air pump body 6 causes the aeration element 53 to spray gas, while the multi-section electric push rod 321 drives the horizontal plate 322 to move downward. The movement of the horizontal plate 322 causes the multiple push rod groups 323 on it to drive the scraper 314 in the corresponding sludge-liquid separation assembly 31 to move forward and reset. After completing the reset and adjustment of the scraper 314, the multi-section electric push rod 321 stops operating, thus completing the equipment preparation work.

[0077] When the pH of the herbal wastewater in the equalization tank 2 is determined to be slightly acidic when it reaches the position of the water level sensor body 23, the controller body 9 controls the drive component 56 in the switching mechanism 5 to move. The motor 561 in the drive component 56 rotates forward, driving the drive gear 562 to move. The drive gear 562 meshes with the driven gear 563, thereby causing the guide component 52 to rotate counterclockwise for switching.

[0078] Since the total number of teeth on the driven gear 563 is twice the total number of teeth on the driving gear 562, when the driving gear 562 rotates 90 degrees, the driven gear 563 moves 45 degrees. When the driven gear 563 drives the guide component 52 to rotate counterclockwise by 45 degrees, the guide groove on the arc plate 51 is in a stable state at this time, so the aeration component 53 will not move up or down during the process of the guide component 52 driving the aeration component 53.

[0079] However, when the aeration element 53 is in circular motion, the external toothed ring 532 on its aeration pipe 531 meshes with the arc-shaped toothed plate 55, thereby realizing the rotation of the aeration pipe 531. When the aeration pipe 531 rotates, the aeration holes at its bottom come into contact with the cleaning brush 54, thus having a certain cleaning effect on the aeration holes.

[0080] Motor 561 continues to rotate 90 degrees, and aeration element 53 moves counterclockwise again along with guide element 52. At this time, because the guide groove on arc plate 51 is in the inclined groove stage, aeration element 53 moves downward during the movement of guide element 52. When aeration element 53 moves downward, the bottom end of aeration pipe 531 applies force to press the filter screen 313 in sludge-liquid separation component 31.

[0081] When the aeration pipe 531 reaches its maximum mileage, the motor 561 stops running, and at this time the filter screen 313 is at the bottom of the receiving box 311. The sealing plug at the bottom of the filter screen 313 then blocks the discharge port on the receiving box 311.

[0082] After adjusting the switching mechanism 5, the controller body 9 opens the control valve on the L-shaped pipe, allowing the herbal wastewater in the equalization tank 2 to enter the corresponding receiving tank 311. As the herbal wastewater enters the receiving tank 311, the controller body 9 simultaneously opens the one-way control valve on the dosing device 57 and the one-way control valve on the corresponding temporary storage device 7. The coagulant in the dosing device 57 and the acid / alkali agent in the corresponding temporary storage device 7 are then added to the herbal wastewater. After the herbal wastewater in the equalization tank 2 is discharged, the controller body 9 closes the control valve on the L-shaped pipe to facilitate the subsequent collection of herbal wastewater.

[0083] Since the quantity and pH of the wastewater from traditional Chinese medicine are limited, the dosage of coagulant aids and acid-base agents is also limited. The opening time of the one-way control valve is controlled by the controller body 9 to achieve the control requirements for the dosage of coagulant aids and acid-base agents.

[0084] The airflow jet from aeration component 53 not only accelerates the neutralization efficiency of the pH of the herbal wastewater, but also further improves the efficiency of the coagulant in flocculating impurities such as medicinal residues in the wastewater. Larger medicinal residues in the wastewater flocculate and settle onto filter screen 313, while smaller medicinal residues and other impurities float to the surface encapsulated by air bubbles.

[0085] After a period of time, once the chemical treatment of the wastewater from traditional Chinese medicine is complete, the controller body 9 activates the switching mechanism 5 to reset. The motor 561 reverses direction, driving the guide component 52 to move clockwise. With the guide component 52 moving 45 degrees clockwise, the aeration component 53 moves upward under the guidance of the guide groove on the arc-shaped plate 51. As the aeration component 53 moves upward, the filter screen 313 in the sludge-liquid separation assembly 31 lacks compressive force, and the filter screen 313 moves upward under the action of the reset spring.

[0086] After the reset spring moves upward, the sealing plug at its bottom is removed from the discharge port, and the chemically treated wastewater from the Chinese herbal medicine enters the biological treatment unit 4 below through the combined pipe for further treatment.

[0087] As the filter screen 313 moves upward, it collects and pushes the impurities in the traditional Chinese medicine wastewater to the top. When the filter screen 313 moves to its maximum height, the impurities on it leave the surface of the traditional Chinese medicine wastewater.

[0088] As motor 561 continues to reverse, the guide component 52 continues to move clockwise. At this time, the aeration component 53 returns to its highest point and then moves in a circular motion only with the guide component 52. During this circular motion, the outer toothed ring 532 of the aeration component 53 contacts the arc-shaped toothed plate 55 again, and the aeration pipe 531 rotates again. Then, under the action of the airflow, when the bottom end of the aeration pipe 531 contacts the cleaning brush 54 again, self-cleaning of the aeration holes is achieved.

[0089] After motor 561 reverses half a turn and stops, the controller body 9 then activates the multi-section electric push rod 321 in the cleaning assembly 32. The push rod assembly 323 causes the scraper 314 to move, thereby scraping away impurities from the filter screen 313. The scraped impurities fall onto the inclined plate 16 and, under the influence of gravity and other factors, flow by gravity into the collection chamber for subsequent cleaning.

[0090] After being treated by the biological treatment unit 4, the water resources are returned to the water tank under the control of the controller body 9 and the water pump body 8, which facilitates the reuse of water resources.

[0091] The controller body 9 controls the adjustment of the switching mechanism 5 based on the information transmitted by the pH sensor body 22 and the water level sensor body 23, repeating the cycle to achieve differentiated treatment of traditional Chinese medicine wastewater with different pH levels.

[0092] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
