Description

Technical Field

[0001] This invention relates to the field of food processing equipment, specifically to a pesticide removal device for agricultural products. Background Technology

[0002] In recent years, with changes in agricultural production methods, pesticide use has been increasing, and pesticide residues have gradually become a focus of public concern. Pesticide residues in agricultural products not only harm consumers' health but also pollute the environment, potentially leading to soil and water contamination. Therefore, effectively removing pesticide residues from agricultural products has become a crucial issue in agricultural production.

[0003] Existing agricultural product cleaning equipment primarily uses basic methods such as water washing, bubble agitation, and spray rinsing, with some devices incorporating ultrasonic or ozone water technologies for auxiliary treatment. These devices are relatively simple in structure and suitable for cleaning surface dirt from general vegetables and fruits, and can also reduce pesticide residues to some extent. In commercial production lines, most cleaning machines focus primarily on large-scale processing and convenient transportation, lacking specificity for the characteristics of different types of agricultural products. Furthermore, while some equipment has circulating water filtration systems, the filtration effect is relatively coarse, only removing larger particulate impurities and failing to thoroughly remove soluble or trace chemical residues.

[0004] Existing pesticide removal devices typically rely on simple water rinsing or bubble treatment. While these can provide initial cleaning of agricultural products, their cleaning depth and effectiveness are limited. Many devices lack multi-layered filtration and purification designs, resulting in the inability to thoroughly remove pesticide residues adhering to the tiny grooves on the surface of fruits and vegetables, especially when cleaning products with complex shapes, where blind spots are easily created. Furthermore, most existing devices have weak water reuse capabilities, often requiring large amounts of water, and the lack of adequate treatment of impurities in the water can lead to secondary pollution. Although some devices incorporate ozone or bubble technology, their coverage and effects are relatively limited, making it difficult to achieve uniform cleaning, and most devices cannot flexibly adjust the spraying pattern according to the characteristics of different agricultural products. At the same time, existing devices lack effective automatic cleaning and intelligent adjustment systems during the cleaning process, easily leading to equipment blockage, frequent maintenance, and consequently affecting overall work efficiency and stability. Summary of the Invention

[0016] This invention provides a pesticide removal device for agricultural products. It has the following beneficial effects: 1. This invention incorporates a screening cylinder driven by a motor inside the washing tank. As agricultural products pass through the bottom of the screening cylinder under the influence of water flow, they are aerated by the aeration components within the equipment, causing them to float to the surface. Impurities in the products then pass through the screen holes of the screening cylinder into the filtration and recovery component below, while the washed products continue to move towards the next step along the direction of the screening cylinder's action. To improve the washing effect, a baffle plate is also installed inside the screening cylinder, biased towards the filtration and recovery component at the front of the washing tank, allowing impurities to flow smoothly into the filtration treatment box for further separation of impurities and water, ensuring improved washing efficiency.

[0017] 2. In this invention, impurities and water are efficiently filtered through the filter cartridge and then reinjected into the cleaning tank for further cleaning. This design not only maximizes water resource utilization but also reduces water waste. The filter cartridge is designed as a detachable module, facilitating cleaning and replacement by operators and ensuring continuous and efficient operation of the equipment. A drain valve is installed at the bottom rear of the cleaning tank to discharge wastewater after prolonged use. The discharged wastewater is sent to the water circulation cleaning assembly for effective filtration. The treated water is then pumped back into the spray assembly, thus achieving water recycling and realizing water conservation and environmental protection.

[0018] 3. This invention incorporates a drive motor at the rear of the screening cylinder, which drives the central rotating shaft in the middle of the cylinder. The rear end of the central rotating shaft is connected to a reciprocating linkage assembly, utilizing the meshing between a half-gear and an internal gear ring to achieve the reciprocating cycle of the top rod. Through the transmission of the connecting rod and the swing rod, the spraying assembly is driven to swing, thereby enabling the spraying assembly to flexibly and evenly spray onto the washed agricultural products. This innovative design makes spraying more precise and efficient, effectively removing residual impurities and pesticide components from the surface of agricultural products, ensuring the thoroughness of the cleaning process and the safety of the agricultural products.

[0019] 4. This invention features a spraying assembly located at the bottom of the cleaning tank. This assembly is linked to the central shaft of the screening cylinder via a transmission belt. The sliding nozzles within the spraying assembly enable both near and far-field spraying, enhancing the spraying effect of the central nozzle. This sliding nozzle design allows for adjustment of the spray angle and range according to the cleaning status of the agricultural products, increasing the ozone dissolution rate and effective range, thereby effectively improving the deep cleaning effect on the agricultural products and ensuring that every part of the products receives thorough cleaning and disinfection.

[0020] 5. In this invention, wastewater discharged through the drain valve flows through the activated carbon filter plate in the cleaning tank. The activated carbon filter plate not only efficiently filters impurities in the water but also purifies the ozone component. The ozone component decomposes into oxygen under the action of the activated carbon filter plate, thereby reducing its environmental impact. To ensure filtration effectiveness, impurities on the filter plate can be cleaned by controlling the brush plate with a control lever. The impurities are then discharged through the wastewater discharge plate, maintaining water cleanliness and ensuring the safe discharge of ozone. This effectively improves water purification efficiency and provides a longer service life for the equipment. Attached Figure Description

This mechanism effectively separates and guides impurities into a dedicated filtration area, preventing impurities from affecting water quality and making the cleaning process more efficient. It can also operate in conjunction with the spraying components 7 and 9.

[0025] Please see the appendix Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 5 , Attachment Figure 6 and attached Figure 7The impurity filtration mechanism 5, through the coordinated operation of multiple components, can efficiently guide the separation and recovery of impurities. The impurity filtration mechanism 5 includes a guiding separation component 51, a filtration recovery component 52, a drive motor 53, and a reciprocating linkage component 54. The filtration recovery component 52 and the reciprocating linkage component 54 are respectively located on the front and rear sides of the washing tank 1 to optimize the operational efficiency of the entire filtration and recovery process. The guiding separation component 51 adopts a screening cylinder 511 structure. Side support frames 513 are provided on both sides of the interior of the screening cylinder 511, which support the stable operation of the screening cylinder 511. The middle part of the screening cylinder 511 is connected to the interior of the washing tank 1 via a central rotating shaft 512. The central rotating shaft 512 allows the screening cylinder 511 to rotate freely inside the washing tank 1. When agricultural products in the water pass through the bottom of the screening cylinder 511, impurities can enter the interior through the sieve holes of the screening cylinder 511, effectively improving the impurity separation efficiency. The output end of the drive motor 53 is fixedly connected to the rear end of the central rotating shaft 512. The power of the drive motor 53 is transmitted to the central rotating shaft 512, realizing the rotation of the screening cylinder 511. In order to effectively transmit the power generated by the rotation to the spraying assembly 9, the two ends of the central rotating shaft 512 are connected to the spraying assembly 9 through two transmission belts 8, thereby ensuring the synchronous movement of the spraying assembly 9. In order to further optimize the cleaning effect, a baffle 514 is installed at an angle in the middle of the central rotating shaft 512. The baffle 514 can effectively agitate the water flow and guide the impurities entering the cleaning tank 1 to the filter treatment box 521 on the front side. The filter treatment box 521 in the filter recovery assembly 52 is fixedly connected to the front side of the cleaning tank 1. A recovery pipe 522 is provided at the bottom of the filter treatment box 521. The recovery pipe 522 is responsible for collecting the water and impurities flowing out of the cleaning tank 1. A filter cylinder 523 is installed on its top. The filter cylinder 523 is used to filter out fine impurities in the water to ensure the cleanliness and efficiency of the circulating water. The reciprocating linkage assembly 54 includes an internal gear ring 541. Limiting rods 542 are fixedly connected to both sides of the top of the internal gear ring 541, and these limiting rods 542 are slidably connected within a groove 543 on the rear side wall of the washing tank 1. A half-gear 544 is installed at the rear end of the central rotating shaft 512. The half-gear 544 meshes with the internal gear ring 541, driving the internal gear ring 541 to move along the groove 543. A push rod 545 is fixedly connected to the end of the internal gear ring 541. The push rod 545 is responsible for pushing the connecting rod 546 to reciprocate, thereby causing the rotating water pipe 701 inside the spray assembly 7 to swing, achieving uniform spraying of agricultural products and ensuring thorough cleaning.

[0026] Please see the appendix Figure 1 -Appendix Figure 3The auxiliary cleaning mechanism 3 is designed to provide additional cleaning power and enhance the cleaning effect of agricultural products. This auxiliary cleaning mechanism 3 includes a water injection component 31, an aeration component 32, a first pump 33, a second pump 34, and a blower 35. The water injection component 31 introduces water into the cleaning tank 1 through a water inlet pipe 311 and sprays the water evenly into the interior of the cleaning tank 1 through multiple water pipe heads 312. The water pipe heads 312 penetrate the side walls of the cleaning tank 1, improving the uniformity of cleaning of agricultural products. The first pump 33 connects to the end of the water inlet pipe 311 through its output end, providing sufficient water flow power to propel the water flow into different areas of the cleaning tank 1, while ensuring stable water flow and avoiding uneven local water flow. The input end of the first pump 33 is connected to the end of the recovery pipe 522 away from the filter treatment box 521. Its main function is to attract and transport wastewater to the recovery system, ensuring timely wastewater return and supporting subsequent water purification and recycling. The aeration assembly 32 consists of an air intake pipe 321 and multiple jet nozzles 322. The jet nozzles 322 penetrate the rear wall of the cleaning tank 1, supplying air into the tank 1 through the air intake pipe 321. This generates bubbles that interact with the water flow, enhancing the turbulence of the water flow and making it easier to remove dirt and pesticide residues from the surface of agricultural products. The air intake pipe 321 is fixedly connected to a blower 35, which provides the necessary airflow power to ensure bubble generation and airflow intensity, thereby enhancing the cleaning effect. Pump 1 33, Pump 2 34, and Blower 35 are all installed inside the outer frame 101 outside the cleaning tank 1 to reduce the equipment's footprint and ensure its stability and safety. The overall design ensures efficient synergy among the components, guaranteeing both the cleanliness and stability of the water flow and enhancing the strength of the bubble action, significantly improving the cleaning effect and efficiency of agricultural products.

[0027] Please see the appendix Figure 2 , Attachment Figure 8 and attached Figure 9The water circulation cleaning component 6 includes a cleaning tank 64.

The drain valve 61 is designed to open quickly when needed, discharging excess sewage and maintaining normal system operation. A clean water circulation pipe 63 is installed on the other side of the cleaning tank 64, responsible for returning purified water to the cleaning tank 1 for reuse. The end of the clean water circulation pipe 63 furthest from the cleaning tank 64 is fixedly connected to the input end of the second pump 34, ensuring that purified wastewater can re-enter the cleaning system via the power input of the second pump 34 for recycling. For ease of cleaning and maintenance, a cover 65 is installed on the top of the cleaning box 64. The cover 65 effectively prevents contaminants from overflowing while providing a convenient opening channel during cleaning and maintenance. Inside the cleaning box 64 is a filter cleaning assembly 66, which effectively removes impurities and contaminants from the water, ensuring water cleanliness and normal equipment operation. The filter cleaning assembly 66 includes an activated carbon filter plate 661, which adsorbs harmful substances and impurities in the water, ensuring effective purification of ozone and pesticide residues. A brush plate 662 is slidably connected to the end of the activated carbon filter plate 661. The brush plate 662 can clean the activated carbon filter plate 661 as needed, ensuring consistent filtration performance. A control lever 663 is fixedly connected to the top side of the brush plate 662, allowing operators to adjust the position and cleaning intensity of the brush plate 662 for convenient periodic cleaning. A sludge discharge plate 664 is provided inside one side of the cleaning box 64. The sludge discharge plate 664 is used to discharge the impurities and dirt separated during the cleaning process, ensuring that there will be no blockage during the filtration process. It also facilitates the timely removal of dirt inside the cleaning box 64, maintaining the good operating condition of the equipment.

[0028] Please see the appendix Figure 3 -Appendix Figure 4The spray assembly 7 includes multiple rotating water pipes 701 and a fixed pipe 703. The rotating water pipes 701 achieve efficient cleaning of agricultural product surfaces via multiple high-pressure nozzles 702 mounted at their bottoms. Each rotating water pipe 701 has multiple high-pressure nozzles 702 installed at its bottom. These nozzles spray cleaning liquid through high-speed water flow, quickly covering the surface of agricultural products and removing attached impurities and pesticide residues. One end of each high-pressure nozzle 702 is rotatably connected to the inside of the fixed pipe 703, which provides stable support and a water flow channel for the entire spraying system. To ensure the continuous and efficient operation of the spray assembly 7, the bottom of the fixed pipe 703 is fixedly connected to the output end of a second pump 34. The second pump 34 provides powerful water flow, ensuring that the high-pressure nozzles 702 can spray sufficient water to clean the agricultural products. To allow for flexible adjustment of the spray angle and direction of the nozzles, multiple high-pressure nozzles 702 are connected in pairs by drive belts 704. A swing arm 705 is installed at the end of the drive belt 704 furthest from the fixed pipe 703. The swing arm 705, as part of the transmission device, is responsible for converting rotational motion into the left-right swinging motion of the nozzles, thus ensuring thorough cleaning of the agricultural product surface. The bottom of the swing arm 705 is connected to the connecting rod 546 via a pivot shaft. This pivot shaft allows the swing arm 705 to rotate and swing at a certain angle during the cleaning process, enabling the high-pressure nozzles 702 to spray along different trajectories, further improving spraying efficiency and coverage.

[0029] Please see the appendix Figure 10 -Appendix Figure 11The spray assembly 9 is a crucial component of the cleaning device, primarily used to enhance the efficiency of cleaning agricultural product surfaces and improve ozone dissolution. The spray assembly 9 includes a driven shaft 901 and a central spray nozzle 907. The driven shaft 901 is connected to the central shaft 512 via two drive belts 8, ensuring effective power transmission. To achieve precise control of the spray assembly 9, the driven shaft 901 has bidirectional threads 902 on both outer sides. These bidirectional threads 902 are connected to a sliding sleeve 903 via outer threads. The sliding sleeve 903 allows for sliding adjustment based on rotational motion, reciprocating on both outer sides of the driven shaft 901 to change the spray range of the sliding nozzle 906. Sliding nozzles 906 are positioned on both sides of the central spray pipe 907. To achieve precise movement of the sliding nozzles 906, rotating rods 904 are provided between the bottom of the two sliding sleeves 903 and the top of the two sliding nozzles 906. The rotating rods 904 allow the sliding nozzles 906 to slide at both ends of the outer side of the central spray pipe 907, preventing deviation during movement and ensuring consistent spraying effect. A top block 905 is fixedly connected to the center of the bottom of the central spray pipe 907, providing fixed support for the spray pipe and ensuring the stability of the spraying assembly 9 during operation. The bottom of the top block 905 is fixedly connected to the inner bottom side of the cleaning tank 1, further increasing the stability of the equipment. A connecting pipe 1001 is installed inside the central spray pipe 907, connecting the ozone tank 10 to the spraying assembly 9. The ozone tank 10 provides strong ozone gas support for the cleaning process, improving the cleaning effect and the removal efficiency of pesticide residues. The ozone tank 10 is installed inside the outer frame 101. The reasonable layout ensures the stability of ozone supply and effectively avoids ozone gas leakage.

[0030] Working Principle: First, agricultural products are placed in the washing tank 1. After washing, they are conveyed to the next step via an inclined conveyor belt 2. A spray assembly 7 is installed above the conveyor belt 2 to perform a final cleaning before the agricultural products are sent out. Two cleaning rollers 4 are installed in the washing tank 1 to physically scrub the surface of the agricultural products and remove adhering substances. The water circulation cleaning assembly 6 introduces the cleaned water into the cleaning tank 64 through the sewage pipe 62. After filtration, the purified water is returned to the washing tank 1 for recycling through the clean water circulation pipe 63. The auxiliary cleaning mechanism 3 provides additional water flow and air bubbles through the water injection assembly 31 and the aeration assembly 32 to further improve the cleaning effect. The impurity guiding and filtering mechanism 5 in the washing tank 1 includes a screening cylinder 511 and a filter recovery assembly 52. ​​Impurities are separated from the water flow through screening and filtration and guided to the filter treatment box 521. The screening cylinder 511 rotates through a central rotating shaft 512, which is powered by a drive motor 53. The rotating shaft is linked with the spray assembly 9 to ensure that the spraying process is synchronized. By linking the driven rotating shaft 901 with the central rotating shaft 512, the sliding nozzle 906 can greatly enhance the spray range and effect of ozone. The spray assembly 7, through the cooperation of the swing rod 705 and the connecting rod 546, utilizes the reciprocating linkage assembly 54 to achieve thorough rinsing of the rotating water pipe 701 and the high-pressure nozzle 702.
