Description

Technical Field

[0001] This utility model relates to the field of rubber product processing technology, and in particular to an ultrasonic cleaning device for food-grade rubber products. Background Technology

[0002] Food-grade rubber products refer to rubber materials and products made from them that meet food safety standards. These products will not negatively affect the safety and quality of food when in contact with it. Food-grade rubber materials do not contain harmful chemicals, can safely come into contact with food, and will not release toxic substances. Many food-grade rubber products can be used in high or low temperature environments and are suitable for various food processing and storage conditions. Food-grade rubber has good resistance to various food components (such as acids, alkalis, oils, etc.) and is not easily corroded or degraded. The surface of food-grade rubber is usually smooth, making it easy to clean and disinfect, and it meets food safety and hygiene requirements.

[0003] A search of Chinese Patent Publication No. CN212442357U reveals an ultrasonic cleaning device, comprising a cleaning machine. A vibrating steel plate is fixedly installed in the middle of the inner wall of the cleaning machine. A cleaning aid mechanism is fixedly connected to the middle of the bottom end of the vibrating steel plate. Ultrasonic transducers are fixedly connected to both sides of the bottom end of the vibrating steel plate. The bottom ends of the two ultrasonic transducers are respectively fixedly connected to the two sides of the top end of an ultrasonic generator. The bottom end of the ultrasonic generator is fixedly connected to the bottom end of the inner wall of the cleaning machine. A shock-absorbing device is fixedly connected to the bottom of the cleaning machine. This ultrasonic cleaning device, according to this invention, allows the cleaning aid mechanism to stir the object to be cleaned, ensuring thorough cleaning. The shock-absorbing device buffers the resonant cleaning machine, reducing the vibration amplitude. The buffer pad and U-shaped rubber pad prevent the machine body from directly contacting other objects and vibrating to produce sound. This not only solves the problem of left-right vibration during the operation of the cleaning machine but also avoids noise generation.

[0004] The aforementioned patent specification mentions in its embodiments that "in specific use, the ultrasonic cleaning device of this utility model involves inserting the bottom end of the stirring device into the through hole of the limiting seat 21, moving the limiting block 24, pushing the pin 23 into the limiting hole on the shaft 22 to fix the stirring device, injecting water and the object to be cleaned into the cleaning machine 1, turning on the switch 7, and the ultrasonic generator 4 and motor 19 starting to work. The ultrasonic generator 4 emits ultrasonic waves, and the motor 19 drives the stirring device to stir the object to be cleaned, so that it can be thoroughly cleaned and avoids the object settling and insufficient cleaning. During the cleaning process, the cleaning machine 1 drives the buffer pad 12 installed at the bottom to vibrate. The buffer pad 12 can prevent the cleaning machine 1 from directly contacting the first partition 8 and vibrating to produce sound. The first partition 8 drives the bottom telescopic sleeve 11 to extend and retract, and the first spring 10 provides buffering, thereby reducing the vibration amplitude and solving the problem of left and right vibration generated when the cleaning machine 1 is working, thus avoiding noise." During use, the object is placed directly inside the device, and the contact surface between the object and the device is prone to cleaning dead spots. After cleaning, the object needs to be left to stand for a long time to remove moisture, which is a rather cumbersome process. Utility Model Content

[0047] Specifically, the cleaning tank 1 is the main structure of the entire cleaning device, responsible for containing the cleaning fluid and the food-grade rubber products to be cleaned. It is corrosion-resistant and high-temperature resistant to adapt to various chemical reactions and temperature changes during the cleaning process. The inner wall of the cleaning tank 1 is smooth to reduce cleaning fluid residue and scale buildup, facilitating cleaning and maintenance. The cleaning fluid tank 24 is used to store the cleaning fluid, ensuring the supply and recovery of the liquid during the cleaning process. The tank is sealed to prevent the evaporation and contamination of the cleaning fluid. The threaded top cover 25 facilitates the periodic addition or replacement of the cleaning fluid. The adsorption component inside the tank effectively removes impurities from the cleaning fluid, extending its service life. The electric push rod 2 provides linear motion, driving the top plate 4. The lifting mechanism can be adjusted according to the height of the items being cleaned. The auxiliary rod 3 provides additional support and stability, ensuring the balance of the top plate 4 during movement.

The drive shaft 7 and the drive sprocket 8 are connected to the driven gear 10 via the chain 11 to form a power transmission system, ensuring smooth flipping action. The ultrasonic generator 21 generates high-frequency sound waves, causing the cleaning fluid to form tiny bubbles. The explosion effect of the bubbles removes dirt.

The cleaning fluid tank 24 has an injection pipe 33 fixedly connected to the top of one side, a switch valve 34 fixedly connected to the other end of the injection pipe 33, a spray pipe 37 fixedly connected to one end of the switch valve 34, multiple nozzles 38 fixedly connected to the inside of the spray pipe 37, and the outside of the spray pipe 37 fixedly connected to the top of the inside of the cleaning tank 1. The cleaning fluid tank 24 has a return pipe 35 fixedly connected to the bottom of one side, a switch valve 36 fixedly connected to the other end of the return pipe 35, and one end of the switch valve 36 fixedly connected to the bottom inner wall of the cleaning tank 1.

[0049] The electrolysis assembly includes a power supply 26, which is externally fixedly connected to the bottom of one side of the cleaning liquid tank 24. A positive electrode 27 is fixedly connected to the output end of the power supply 26, and a negative electrode 28 is fixedly connected to the output end of the power supply 26. The positive electrode 27 and the negative electrode 28 are externally fixedly connected to the inside of the cleaning liquid tank 24.

[0050] The adsorption assembly includes a bottom activated carbon adsorption layer 30 and a top activated carbon adsorption layer 32. The bottom activated carbon adsorption layer 30 is fixedly connected to the bottom of the inner wall of the cleaning liquid tank 24, i.e., the top of the return pipe 35. Bottom mesh baffles 29 are fixedly connected to both the upper and lower sides of the bottom activated carbon adsorption layer 30. The top activated carbon adsorption layer 32 is fixedly connected to the top of the inner wall of the cleaning liquid tank 24, i.e., the bottom of the injection pipe 33. Top mesh baffles 31 are fixedly connected to both the upper and lower sides of the top activated carbon adsorption layer 32.

[0051] Specifically, the protective cover 17 protects the interior of the cleaning tank 1, preventing external contaminants from entering. The transparent observation window 20 allows the user to observe the cleaning process in real time, facilitating monitoring of the cleaning effect. It is easy to open and close, making it convenient for user operation. The electrolysis component is used to activate and regenerate the cleaning solution, improving the cleaning effect. The power supply 26 provides current, causing an electrolytic reaction between the positive electrode 27 and the negative electrode 28, enhancing the cleaning solution's decontamination ability and ensuring the corrosion resistance and conductivity of the electrodes to improve electrolysis efficiency. The adsorption component further purifies the cleaning solution, removing contaminants. The activated carbon adsorption layer removes impurities from the water through physical adsorption. To improve the cleanliness of the cleaning fluid, the bottom mesh barrier plate 29 and the top mesh barrier plate 31 prevent activated carbon particles from falling off while ensuring smooth liquid flow. The injection pipe 33 and the return pipe 35 are used for the injection and recovery of the cleaning fluid to ensure the recycling of the cleaning process. Switch valve one 34 and switch valve two 36 control the flow of the cleaning fluid, making it easy to add and recover the cleaning fluid as needed. The lifting handle 16 and the rewinder 18 are designed for easy operation and improved user experience. The lifting handle 16 allows users to quickly open or close the protective cover 17 when necessary, and the rewinder 18 is used to store the lifting cable 19, keeping it neat and preventing cable tangling.

[0052] Working principle: First, the user opens the protective cover 17 by pulling the handle 16 to check the interior of the cleaning tank 1 and places the food-grade rubber product to be cleaned in the placement frame 13. The placement frame 13 is fixed with grids 14 on all four sides to ensure the product does not sink into the cleaning solution during the cleaning process. After closing the protective cover 17, the electric push rod 2 starts working, driving the top plate 4 to rise and fall, ensuring the space inside the cleaning tank 1 is suitable for the cleaning operation. At this time, the cleaning solution in the cleaning solution tank 24 is injected into the cleaning tank 1. The injection pipe 33 controls the inflow through the switch valve 34, and the multiple nozzles 38 of the spray pipe 37 spray the cleaning solution evenly.

[0053] Next, the ultrasonic generator 21 is activated, generating high-frequency sound waves. These waves are converted from electrical energy into mechanical energy through multiple transducers 22, forming microbubbles. These bubbles rapidly expand and burst in the cleaning solution, generating shock waves that effectively remove dirt from the surface of the rubber product. After the cleaning process has continued for a certain period of time, the motor 6 is activated, driving the flipping mechanism to flip the product within the placement frame 13, thereby ensuring that the cleaning solution can fully cover all surfaces of the product and improve the cleaning effect.

[0054] After cleaning, the dryer 23 in the drying assembly starts working, quickly removing moisture from the product surface through heating and air drying to ensure the cleaned rubber product dries quickly. Simultaneously, the cleaning solution, after ultrasonic treatment in the cleaning tank 1, flows through the return pipe 35 and, controlled by the second switch valve 36, returns to the cleaning solution tank 24 for recycling. At this time, the electrolysis assembly starts working, with the power supply 26 providing current, and an electrolytic reaction occurs between the positive electrode 27 and the negative electrode 28, activating the cleaning solution and enhancing its cleaning ability.

[0055] Finally, impurities in the cleaning solution are removed through the bottom activated carbon adsorption layer 30 and the top activated carbon adsorption layer 32 in the adsorption assembly, ensuring the cleanliness of the cleaning solution. After cleaning, the user can open the protective cover 17 again to remove the cleaned and dried rubber product, thus completing the entire cleaning process.

[0056] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
