Description

Technical Field

[0001] This utility model belongs to the field of plant essential oil extraction technology, specifically a wastewater treatment structure for camphor leaf extraction. Background Technology

[0002] The wastewater generated during the extraction and processing of camphor leaves contains a large amount of emulsified oil, suspended solids, and organic matter, which would cause serious environmental pollution if directly discharged. Currently, the treatment of this type of wastewater typically involves adding demulsifiers, coagulants, and flocculants in the pretreatment stage to break up the oil-water emulsion and promote the formation of flocs from suspended solids, creating conditions for subsequent deep purification. However, the efficiency of wastewater treatment is closely related to the accuracy of reagent dosing. In traditional treatment processes, the automation control and metering accuracy of the dosing process directly affect the demulsification and flocculation effects, thus determining the load on subsequent treatments and the final water quality.

[0003] In existing technologies, wastewater treatment dosing devices generally suffer from low levels of automation. Some devices rely on manual dosing of chemicals, which is not only labor-intensive but also makes it difficult to adjust the dosage in real time according to the wastewater quality. This easily leads to either overdosing or underdosing of chemicals. The former results in waste of chemicals and increased treatment costs, while the latter leads to incomplete demulsification, poor floc formation, and reduced solid-liquid separation efficiency. Furthermore, traditional dosing devices often use simple valve control or gravity flow methods, lacking reliable sealing structures and metering components. Chemical leakage is prone to occur during transport, polluting the surrounding environment. Simultaneously, it is difficult to control the dosage of chemicals flowing into the treatment tank, resulting in unstable treatment effects. Considering the characteristics of camphor leaf extraction wastewater, there is an urgent need for an automated dosing mechanism that can achieve controllable and well-sealed chemical dosing to solve the problems of low efficiency and poor sealing reliability in existing technologies.

[0004] Patent application CN202322112760.9 discloses a wastewater treatment device for rose essential oil production. However, this device's dosing process is controlled solely by the start and stop of a metering pump, lacking real-time feedback and adjustment capabilities to changes in wastewater quality. For example, when the concentration of emulsified oil in the wastewater fluctuates, it is difficult to adjust the dosage, requiring repeated parameter settings, resulting in low dosing efficiency and difficulty adapting to dynamic changes in wastewater quality during industrial production. Furthermore, the connection between the reagent tank and pipelines relies solely on conventional interfaces, which are prone to leakage due to vibration and corrosion over long-term use, polluting the surrounding environment and jeopardizing operational safety.

[0005] The purpose of this utility model is to provide a wastewater treatment structure for camphor leaf extraction, so as to solve the following technical problems mentioned in the background art:

[0006] Existing technologies suffer from low efficiency and poor sealing reliability in manual drug application.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0029] Example:

[0030] A wastewater treatment structure for camphor leaf extraction includes a pretreatment tank 1, a posttreatment tank 5, a filtration mechanism, a chemical tank 7, and a dosing mechanism 6. The pretreatment tank 1 is located on top of the posttreatment tank 5, the filtration mechanism is located between the pretreatment tank 1 and the posttreatment tank 5, and the chemical tank 7 and the dosing mechanism 6 are located on the pretreatment tank 1. The dosing mechanism 6 includes a dispensing pipe 12, a chemical cartridge 19, a fixed connector 16, a sealing connector 17, a rotating rod 20, a rotating component 14, a sealing flap 21, a first control cylinder 15, a second control cylinder 18, a moving rod 22, and a sealing head 25. The dispensing pipe 12 communicates with the chemical tank 7, and the sealing connector 17 is connected to the bottom of the dispensing pipe 12. On one side, the fixed connector 16 is connected to the sealing connector 17, the rotating rod 20 is rotatably connected to the fixed connector 16, the rotating part 14 and the sealing flap 21 are respectively fixed to the two ends of the rotating rod 20 and the sealing flap 21 is sealed and connected in the sealing connector 17, the bottom of the first control cylinder 15 is hinged to the fixed connector 16, and the telescopic rod of the first control cylinder 15 is hinged to the rotating part 14; the medicine cartridge 19 is located at the bottom of the medicine tube 12, the bottom of the medicine cartridge 19 is provided with an opening, a sealing head 25 is provided at the opening, a moving rod 22 is fixedly connected to the sealing head 25, the moving rod 22 is connected to the telescopic rod of the second control cylinder 18, and the second control cylinder 18 is fixedly connected to the top of the medicine cartridge 19.

[0031] The wastewater from camphor leaf extraction contains a significant amount of emulsified oil and suspended solids. In pretreatment tank 1, coagulants, flocculants, and demulsifiers are added to break up the oil-water emulsion and cause the suspended solids to form dense flocs. The deemulsified oil remains suspended on the surface of pretreatment tank 1. The flocs and water are then discharged, and a central filtration system filters the flocs. The pre-filtered water enters posttreatment tank 5, where further purification is performed. This includes anaerobic treatment with anaerobic bacteria to reduce the concentration of organic matter, membrane separation to further remove pollutants, and ozone disinfection.

[0032] The dosing mechanism 6 facilitates dosing. Specifically, during use, the first control cylinder 15 extends, driving the rotating component 14 to rotate. The rotating component 14 drives the rotating rod 20 to rotate, which in turn drives the sealing flap 21 to rotate. After the sealing flap 21 rotates, the sealing connection between it and the sealing connector 17 is released, creating a gap between them. The liquid medicine in the medicine tank 7 enters the medicine cartridge 19 through the dosing pipe 12, and the amount of liquid medicine is measured in the medicine cartridge 19. Once the amount of liquid medicine is sufficient, the first control cylinder 15 retracts, driving the rotating component 14 to rotate. The rotating component 14, through the rotating rod 20, drives the sealing flap 21 to rotate, restoring the sealing connection between the sealing flap 21 and the sealing connector 17, and closing the dosing pipe 12. The second control cylinder 18 is then activated. The extension rod of the second control cylinder 18 retracts, driving the sealing head 25 to open the opening at the bottom of the medicine cartridge 19. After the opening is opened, the liquid medicine in the medicine cartridge 19 flows into the pretreatment tank 1. After the chemical solution has completely flowed into the pretreatment tank 1, the telescopic rod of the second control cylinder 18 extends and drives the sealing head 25 to block the opening at the bottom of the chemical cartridge 19. Then the next chemical addition can be carried out.

[0033] In a preferred embodiment, an inlet pipe 2 is connected to one side of the pretreatment tank 1. The inlet pipe 2 is used to introduce the camphor leaf extraction wastewater to be treated into the pretreatment tank 1 so that reagents can be added for preliminary treatment such as demulsification and flocculation.

[0034] In a preferred embodiment, a baffle 9 is provided in the pretreatment tank 1, dividing the pretreatment tank 1 into two parts. The baffle 9 is provided with connecting holes 10. The baffle 9 is designed to prolong the wastewater retention time, promote oil flotation, floc settling and water stratification separation, and improve the demulsification and flocculation effect.

[0035] In a preferred embodiment, an overflow pipe 11 is provided on one side of the pretreatment tank 1 near the top. The overflow pipe 11 is used to control the liquid level in the pretreatment tank 1, discharge the floating emulsified oil, and prevent liquid overflow.

[0036] In a preferred embodiment, a stirring mechanism 8 is provided on the pretreatment tank 1. The stirring mechanism 8 includes a stirring motor, a stirring shaft, and stirring blades. The stirring motor is mounted on the pretreatment tank 1, the stirring shaft is connected to the output shaft of the stirring motor, and the stirring blades are located at the bottom of the stirring shaft and inside the pretreatment tank 1. The stirring mechanism 8 drives the stirring shaft and blades to rotate through the stirring motor, promoting rapid and uniform mixing of the reagent and wastewater, accelerating demulsification and flocculation reactions, and improving treatment efficiency.

[0037] In a preferred embodiment, the filtration mechanism includes a guide channel 3 and a filter screen 4. The guide channel 3 is connected to the top of the post-treatment tank 5, and the filter screen 4 is disposed on the guide channel 3. The guide channel 3 guides the pre-treated wastewater from the pre-treatment tank 1 into the post-treatment tank 5, while the filter screen 4 intercepts suspended solids such as flocs, achieving preliminary solid-liquid separation.

[0038] In a preferred embodiment, the guide channel 3 has a V-shaped structure. The V-shaped guide channel 3 gathers water flow through its inclined walls, allowing wastewater to flow centrally through the filter screen 4, thereby improving the floc interception efficiency. At the same time, the shape of the filter screen 4 is adapted to the shape of the guide channel 3, so that the filtered flocs can be concentrated in the middle position, making it convenient to remove the flocs.

[0039] In a preferred embodiment, the post-treatment tank 5 is equipped with ultraviolet lamps. The ultraviolet lamps disinfect and sterilize by irradiating and inactivating bacteria, viruses, and other microorganisms in the water, thereby improving the safety of the effluent water quality.

[0040] In a preferred embodiment, a flange 13 is provided on one side of the bottom of the dispensing tube 12, and a sealing connector 17 is connected to the flange 13 by bolts. The connection between the flange 13 and the bolts enhances the connection strength and sealing performance between the dispensing tube 12 and the sealing connector 17, while also facilitating disassembly and maintenance.
