Description

Technical Field

[0001] This invention belongs to the field of marigold pressing technology, and particularly relates to a device and method for treating marigold pressing wastewater. Background Technology

[0002] In the processing of marigolds, pressing is often used to extract natural pigments, essential oils, or active ingredients. This process generates a large amount of wastewater containing flower residue, pigments, organic matter residues, and some pesticide residues. This type of wastewater is characterized by high color, high COD concentration, and poor biodegradability. If it is discharged directly into the environment without effective treatment, it will cause serious pollution to water bodies. Therefore, by using special operating procedures such as sludge dewatering, organic residue concentration, and separation and reuse of harmful substances in water bodies, wastewater treatment efficiency can be improved, pollution load can be reduced, and it is beneficial to achieve wastewater reuse or discharge in compliance with standards.

[0003] In existing technologies, during wastewater treatment, flocculants and subsequent purification agents are usually added directly to the same location, which can easily lead to uneven distribution of various agents in the water. This addition method not only affects the stability of the flocculation reaction and easily causes phenomena such as floc shedding and loose floc structure, but also affects the effectiveness of subsequent purification agents, reducing the overall treatment efficiency. At the same time, the non-concentrated distribution of flocs makes subsequent cleaning and discharge more difficult, increasing the operating burden and maintenance costs.

[0004] Based on this, the present invention designs a marigold pressing wastewater treatment device and method to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the problem in the prior art where flocculants and subsequent purification agents are usually added directly to the same location during wastewater treatment, which easily leads to uneven distribution of various agents in the water. This addition method not only affects the stability of the flocculation reaction and easily causes phenomena such as floc shedding and loose floc structure, but also affects the effectiveness of subsequent purification agents and reduces the overall treatment efficiency. Therefore, this invention proposes a marigold pressing wastewater treatment device and method.

[0012] The moving device also includes a sliding rod and a threaded cap. The threaded cap is sleeved on the reciprocating screw. The sliding rod is fixedly connected to two vertical plates. A connecting plate is fixedly connected to the first motor and is fixedly connected to the front of the treatment tank. The threaded cap and the sliding rod form a sliding connection. A horizontal plate is installed on the threaded cap. Both material cylinders are installed on the upper surface of the horizontal plate. Two second motors are fixedly connected to the horizontal plate. The output ends of the two second motors are fixedly connected to one side of the auger.

[0013] As a further description of the above technical solution:

[0014] The inner diameter of the barrel is larger than the diameter of the auger cross-section, and the two are fitted together.

[0015] As a further description of the above technical solution:

[0016] A second reel is installed on both the outer side of the second rotating shaft and the outer side of the purification tank. The two second reels are covered with the same second belt. A second stirring blade is fixedly connected to the outer side of one of the second reels, and the second stirring blade is rotatably connected inside the purification tank. The output ends of the two augers are respectively located above the treatment tank and the purification tank.

[0017] As a further description of the above technical solution:

[0018] The scraping device includes two sliders, two chutes, and a receiving box. The two chutes are symmetrically opened on the inner wall of the treatment tank. The sliders are slidably connected in the chutes. The same moving rod is installed in the two sliders. A collar is provided around the moving rod. A moving plate is fixedly connected below the collar. A rubber plate is fixedly connected below the moving plate. A limiting ring is provided around the moving rod. A locking rod is fixedly connected to the moving rod. The locking rod is fixedly connected to the lower surface of the horizontal plate. The receiving box is connected through the treatment tank. A storage box is fixedly connected below the receiving box. The receiving box inside the treatment tank is set with an inclined feed port for easy material receiving.

[0019] As a further description of the above technical solution:

[0020] The scraping device also includes a squeezing block and a circular groove. The circular groove is formed on the inner wall of the treatment pool. The squeezing block and the circular groove are slidably connected. A return spring is installed inside the squeezing block and is fixedly connected inside the circular groove.

[0021] As a further description of the above technical solution:

[0022] The rubber sheet overlaps the inner wall of the treatment tank, and the extrusion surface of the extrusion block is set to be semi-circular and extends into the treatment tank.

[0023] As a further description of the above technical solution:

[0024] The pretreatment device includes a treatment box, which is fixedly connected to the upper surface of the discharge pool. Two inclined filter plates are installed inside the treatment box. A handle is installed on the front of the filter plates. A connecting shell is installed on the upper surface of the treatment box. A box body is fixedly connected to one side of the connecting shell. A collection box is slidably connected inside the box body. A water outlet is opened on the contact surface between the box body and the treatment box, and a water outlet is opened on one side of the collection box.

[0025] The present invention also provides a method for treating marigold pressing wastewater, comprising the following steps:

[0026] S1: When in use, the flocculant and the purification agent are put into the two feed hoppers respectively. The first motor is started. The output end of the first motor drives the first rotating shaft to rotate. The first rotating shaft synchronously drives the first stirring blade in the treatment tank to perform stirring operation. At the same time, it drives the connected first winding wheel to rotate. The first belt drives the other first winding wheel to rotate, which drives the reciprocating screw to rotate.

[0027] S2: When the reciprocating screw rotates, the threaded cap moves axially, and the horizontal plate moves synchronously in a straight line with the threaded cap. The two material cylinders on the horizontal plate move in the same direction during the movement. After the second motor is started, the output end of the second motor drives the auger in the material cylinder to rotate. The auger discharges the material in the hopper at a constant speed and transports it in batches to the top of the treatment pool and purification pool.

[0028] S3: When the horizontal plate moves, the locking rod drives the moving rod to slide along the chute. The slider runs along the inner wall of the treatment tank in the chute. The moving rod drives the collar, moving plate and rubber plate to move synchronously. The rubber plate slides against the water surface to the top of the inclined feed inlet of the receiving box, pushing the flocculent material into the receiving box. The limit ring controls the rubber plate angle to be stable.

[0029] S4: The rubber sheet contacts the extrusion block during the return phase. The extrusion block is embedded in the circular groove during the return sliding process. The moving plate drives the rubber sheet to rotate and deflect outside the moving rod. The rubber sheet deflects and leaves the water surface, maintaining a state of operation away from the liquid surface and not contacting the water. The extrusion block is in an extended state during the cleaning phase, providing a structural contact point.

[0030] S5: After the water flows into the treatment tank, it passes through the inclined filter plate. The filter plate blocks solid impurities and guides them into the collection tank. The liquid enters the discharge pool through the outlet hole. The remaining liquid flows back through the outlet hole of the collection tank. The upper surface of the treatment tank is equipped with a handle for removing and replacing the filter plate.

[0031] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0032] 1. In this invention, two independent feed hoppers are set up to hold flocculant and subsequent purification agents, respectively, avoiding the interference problem caused by the concentrated addition of multiple agents in traditional wastewater treatment. After the first motor is started, the first rotating shaft drives the first stirring blade installed in the treatment tank to rotate at high speed, achieving preliminary mixing of the water. At the same time, the first winding wheel on the first rotating shaft drives the first belt drive to drive the first winding wheel on the other side to rotate, thereby driving the reciprocating screw connected to it to rotate. The reciprocating screw drives the threaded cap to move axially back and forth, and the threaded cap drives the horizontal plate installed on it to move synchronously. The movement further drives the two material cylinders above the horizontal plate to reciprocate. During operation, the second motor drives the auger inside the material cylinder to rotate continuously, pushing the flocculant or purifying agent in the feed hopper out at a uniform speed and spreading it evenly to different areas of the treatment tank or purification tank. Throughout the spreading process, the first stirring blade and the second stirring blade set in the purification tank rotate together to ensure that the two agents are fully mixed and diffused in the water, effectively improving the uniformity of addition, enhancing the stability of flocculation and purification reactions, and fundamentally improving the problems of deflocculation and reduced reaction efficiency caused by concentrated addition of agents.

[0033] 2. In this invention, to further improve the automation level of the processing and the efficiency of floc removal, a scraping device linked to the moving device structure is provided. During the reciprocating movement of the horizontal plate, the moving rod installed on the slider moves horizontally through the locking rod. The slider slides along the groove set in the inner wall of the treatment tank, guiding the entire scraping system to move in the tank. In this system, the moving rod linkage collar, the moving plate and the rubber plate move synchronously, so that the rubber plate is in contact with the liquid surface of the treatment tank and continuously scrapes the floc residue formed on the water surface along the direction of movement. The floc is concentrated and pushed to the inclined feed port above the receiving box. Under the action of the limiting ring, the rubber plate maintains a reasonable scraping angle to ensure sufficient thrust and prevent the return thrust from weakening due to excessive angle. This achieves fast and efficient collection of floc. This structure can automatically complete the centralized cleaning of flocs once in each reciprocating cycle, effectively reducing manual intervention and scraping residue problems, and improving the continuity and stability of the overall operation.

[0034] 3. In this invention, during the return stroke of the scraping device, to prevent the rubber plate from interfering with the water surface or causing flocculation disturbance when it runs in reverse, an extrusion block and a circular groove structure with an automatic lifting function are designed. Specifically, when the rubber plate drives the collar and the moving plate in the return stroke, it will be squeezed by the top surface of the extrusion block fixed to the inner wall of the treatment tank, thereby causing the moving component to rotate and the rubber plate to automatically deflect away from the water surface. During the return stroke, the rubber plate runs suspended in the air and does not contact the water surface, effectively preventing the back mixing of flocculation and secondary disturbance of the water. During the cleaning stage, under the limiting action of the limiting ring, the rubber plate can provide a continuous and stable thrust to ensure that the flocculation is pushed into the receiving box, while the extrusion block is compressed into the circular groove to form a hidden state, without interfering with the scraper action. This achieves a closed-loop cleaning process in which the scraper completes effective scraping in only one direction and does not contact the treatment medium during the return stroke, greatly improving the scraping efficiency and service life.

[0035] 4. In this invention, the pretreatment device is located above the discharge tank. Its treatment tank contains two inclined filter plates to intercept large solid particles in the wastewater, such as petal residue and coarse fibers. Wastewater enters the treatment tank through the connecting shell. As it flows through the inclined filter plates, the solid particles slide down into the collection tank below. The filtered liquid enters the discharge tank through the outlet hole for subsequent treatment. This structure effectively achieves primary solid-liquid separation, preventing large particles from directly entering the purification process and causing blockages or equipment wear. Furthermore, the presence of operable handles on the filter plates allows users to easily remove them for cleaning or replacement, improving equipment maintainability. Excess water can be returned to the discharge tank through the drain hole in the collection tank, preventing water retention and creating a recycling path, thus improving the overall system's resource utilization efficiency and operational stability.

[0051] Specifically, such as Figure 5-8As shown, the scraping device 8 includes two sliders 802, two chutes 801, and a receiving box 809. The two chutes 801 are symmetrically opened on the inner wall of the treatment tank 3. The sliders 802 are slidably connected in the chutes 801. The same moving rod 803 is installed in the two sliders 802. The moving rod 803 is fitted with a collar 804. A moving plate 805 is fixedly connected below the collar 804. A rubber plate 806 is fixedly connected below the moving plate 805. The rubber plate 806 is attached to the inner wall of the treatment tank 3.

[0052] The moving rod 803 is fitted with a limiting ring 808, and a locking rod 807 is fixedly connected to the moving rod 803.

[0053] A reset spring 813 is installed inside the extrusion block 812. The reset spring 813 is fixedly connected inside the circular groove 811. The rubber plate 806 overlaps the inner wall of the treatment pool 3. The extrusion surface of the extrusion block 812 is set to be semi-circular and extends into the treatment pool 3.

[0054] Specifically, such as Figure 9 As shown, the pretreatment device 9 includes a treatment box 901, which is fixedly connected to the upper surface of the discharge pool 2. Two inclined filter plates 902 are installed inside the treatment box 901. A handle 903 is installed on the front of the filter plates 902. A connecting shell 904 is installed on the upper surface of the treatment box 901. A box body 905 is fixedly connected to one side of the connecting shell 904. A collection box 906 is slidably connected inside the box body 905. The collection box 906 is slidably installed inside the box body 905, so that it can be pulled out or inserted in a set direction. At the same time, liquid-solid separation is achieved through the water outlet 907 provided on the contact surface, and the fit is compact.

[0055] A water outlet 907 is provided on the contact surface of the tank 905 and the treatment tank 901, and a water outlet 907 is provided on one side of the collection tank 906.

[0056] The present invention also provides a method for treating marigold pressing wastewater, comprising the following steps:

[0057] S1: When in use, the flocculant and the purification agent are respectively put into the two feed hoppers 715, the first motor 702 is started, the output end of the first motor 702 drives the first rotating shaft 703 to rotate, the first rotating shaft 703 synchronously drives the first stirring blade 705 in the treatment tank 3 to perform stirring operation, and at the same time drives the connected first winding wheel 707 to rotate, and through the first belt 706, the other first winding wheel 707 is driven to rotate, which drives the reciprocating screw 710 to rotate;

[0058] S2: When the reciprocating screw 710 rotates, the thread cap 712 moves axially, and the horizontal plate 713 moves synchronously with the thread cap 712. The two material cylinders 714 on the horizontal plate 713 move in the same direction during the movement. After the second motor 716 is started, the output end of the second motor 716 drives the auger 717 in the material cylinder 714 to rotate. The auger 717 discharges the material in the hopper at a constant speed and transports it in batches to the treatment pool 3 and the purification pool 4.

[0059] S3: When the horizontal plate 713 moves, the locking rod 807 drives the moving rod 803 to slide along the slide groove 801. The slider 802 runs guided along the inner wall of the treatment tank 3 in the slide groove 801. The moving rod 803 drives the collar 804, the moving plate 805 and the rubber plate 806 to move synchronously. The rubber plate 806 slides against the water surface to above the inclined feed inlet of the receiving box 809, pushing the flocculent material into the receiving box 809. The limiting ring 808 controls the angle of the rubber plate 806 to be stable.

[0060] S4: During the return stroke, the rubber plate 806 contacts the extrusion block 812. During the return stroke sliding process, the extrusion block 812 is embedded in the circular groove 811. The moving plate 805 drives the rubber plate 806 to rotate and deflect outside the moving rod 803. The rubber plate 806 deflects and leaves the water surface, maintaining a state of operation away from the liquid surface and not contacting the water. During the cleaning stage, the extrusion block 812 is in an extended state, providing a structural contact point.

[0061] S5: After the water flows into the treatment tank 901, it passes through the inclined filter plate 902. The filter plate 902 blocks solid impurities and guides them into the collection tank 906. The liquid enters the discharge pool 2 through the outlet hole 907. The remaining liquid flows back through the outlet hole 907 of the collection tank 906. The upper surface of the treatment tank 901 is provided with a handle 903 for the removal and replacement of the filter plate 902.

[0062] Working principle and usage:

[0063] By setting up two independent feed hoppers 715, which are used to hold flocculants and subsequent purification agents respectively, the interference problem caused by the centralized addition of multiple agents in traditional wastewater treatment is avoided. After the first motor 702 is started, the first rotating shaft 703 drives the first stirring blade 705 installed in the treatment tank 3 to rotate at high speed, so as to achieve the initial mixing of the water. At the same time, the first winding wheel 707 on the first rotating shaft 703 drives the first belt 706 to drive the first winding wheel 707 on the other side to rotate, thereby driving the reciprocating screw 710 connected to it to rotate. The reciprocating screw 710 drives the threaded cap 712 to move axially back and forth. The threaded cap 712 drives the horizontal plate 713 installed on it to move synchronously, further driving the two material cylinders 714 above the horizontal plate 713 to reciprocate. During the operation, the second motor 716 drives the auger 717 in the material cylinder 714 to rotate continuously, pushing the flocculants or purification agents in the feed hopper 715 out at a uniform speed and spreading them evenly to different areas of the treatment tank 3 or purification tank 4.

[0064] During the reciprocating movement of the horizontal plate 713, the locking rod 807 drives the moving rod 803 installed on the slider 802 to move horizontally. The slider 802 slides along the groove 801 set in the inner wall of the treatment tank 3, guiding the entire scraping system to move in the tank. In this system, the moving rod 803 moves synchronously with the linkage collar 804, the moving plate 805 and the rubber plate 806, so that the rubber plate 806 is in contact with the liquid surface of the treatment tank 3 and continuously scrapes the flocculent residue formed on the water surface along the direction of movement. The flocculent is concentrated and pushed to the inclined feed port above the receiving box 809. Under the action of the limiting ring 808, the rubber plate 806 maintains a reasonable scraping angle to ensure sufficient thrust and prevent the return thrust from weakening due to excessive angle.

[0065] When the rubber plate 806 drives the collar 804 and the moving plate 805 on the return trip, it will be squeezed by the top surface of the extrusion block 812 fixed on the inner wall of the treatment tank 3, which will cause the moving component to rotate, causing the rubber plate 806 to automatically deflect and move away from the water surface. During the return trip, the rubber plate 806 runs in the air and does not contact the water surface, which effectively prevents the back mixing of flocs and secondary disturbance of the water. During the cleaning stage, under the limiting action of the limiting ring 808, the rubber plate 806 can provide a continuous and stable thrust to ensure that the flocs are pushed into the receiving box 809, while the extrusion block 812 is compressed into the circular groove 811 to form a hidden state, which does not interfere with the scraper action, thereby realizing a closed-loop cleaning process in which the scraper completes effective scraping in only one direction and does not contact the treatment medium during the return trip.

[0066] During the flow through the inclined filter plate 902, the solid matter slides down into the collection box 906 below. The filtered liquid enters the discharge pool 2 through the water outlet 907 for subsequent treatment. This structure effectively achieves primary solid-liquid separation, preventing large particles from directly entering the purification process and causing blockage or equipment wear. At the same time, by providing an operable handle 903 on the filter plate 902, it is easy for users to pull out the filter plate 902 for cleaning or replacement.
