[0021] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] refer to Figure 1-4 An ultrasonic cleaning device for cleaning metal debris includes a shell 1 and a conveying module arranged on the surface of the shell 1. The conveying module is used to convey the metal debris to be cleaned. An ultrasonic cleaning module 2 and a spray module 3 are respectively arranged on the surface of the shell 1 along the conveying direction of the conveying module. The ultrasonic cleaning module 2 is used to remove oil from the metal debris to be cleaned, and the spray module 3 is used to rinse the metal debris from which the oil has been removed.

[0023] In this embodiment, the ultrasonic cleaning module 2 utilizes the strong cavitation effect, straight flow and acceleration of ultrasonic waves in the cleaning liquid to penetrate into the tiny gaps and pores on the surface of the metal debris, effectively disintegrate and remove the oil, coolant and other processing residues attached to the metal debris, and achieve efficient cleaning. After ultrasonic cleaning, the spray module 3 further rinses the metal debris to ensure that there is no residue on the surface of the metal debris after the oil is removed, achieving a higher cleanliness standard. This dual cleaning mechanism ensures the thoroughness of the cleaning effect. The equipment integrates a conveying module that can automatically convey the metal debris to be cleaned to the ultrasonic cleaning module 2 and the spray module 3 for cleaning without manual intervention, greatly improving the degree of automation of the cleaning operation and reducing labor costs. The equipment is flexibly designed and can adjust the working parameters of the ultrasonic cleaning module 2 and the spray module 3 according to the characteristics and cleaning requirements of different metal debris, such as cleaning time, type of cleaning liquid, spray pressure, etc., to meet the cleaning needs in different scenarios.

[0024] It should be noted that the oil content of metal scraps after cleaning by cleaning equipment is controlled below 3%. The metal scraps produced in this way are classified as general solid waste, which reduces the harmful gases emitted during transportation and reuse, as well as the difficulty and cost of treating harmful gas emissions, reduces pollution risks, and protects the ecological environment.

[0025] Preferably, the shell 1 includes a support frame 11, on which an inlet 12, an ultrasonic cleaning pool 13, a spray station 14 and an outlet 15 are arranged in sequence along the conveying direction of the conveying module. The cleaning pool 13 is arranged to be tilted downward on both sides along the conveying direction of the conveying module, and is used to store cleaning agents and install ultrasonic equipment 21.

[0026] In this embodiment, the support frame 11 serves as the skeleton of the entire equipment, and the feed port 12, ultrasonic cleaning tank 13, spray station 14 and discharge port 15 are rationally arranged, so that the cleaning process of metal debris is smooth and unobstructed, and the cleaning efficiency is improved. At the same time, the compact structural design also saves space and facilitates the installation and maintenance of the equipment; the setting of the feed port 12 and the discharge port 15 makes the addition and removal of metal debris convenient and quick, reducing the complexity and time cost of manual operation. In addition, the design of the downward tilt of both sides of the ultrasonic cleaning tank 13 not only facilitates the collection and recycling of cleaning agents, but also facilitates the maintenance of the ultrasonic equipment 21 and The interior of the ultrasonic cleaning tank 13 is maintained and cleaned; the downwardly inclined design of the two sides of the ultrasonic cleaning tank 13 helps to form a certain water flow direction during the cleaning process, so that the cleaning agent can be more evenly covered on the surface of the metal debris, thereby improving the cleaning effect. At the same time, this design is also conducive to guiding the floating oil and impurities generated during the cleaning process to the bottom of the tank, thereby maintaining the cleanliness of the cleaning liquid; the inclined cleaning tank 13 design is conducive to the recovery and reuse of the cleaning agent, thereby reducing the waste and discharge of the cleaning agent, and meeting the requirements of environmental protection. At the same time, by reasonably controlling the amount of the cleaning agent and recycling it, the production cost can be reduced and the resource utilization efficiency can be improved.

[0027] Preferably, a heating device 22 is provided in the ultrasonic cleaning tank 13, and the heating device 22 is used to heat the cleaning agent.

[0028] In this embodiment, heating the cleaning agent can significantly reduce its surface tension and viscosity, making it easier for the cleaning agent to penetrate into the tiny gaps and pores on the surface of the metal debris, thereby more effectively disintegrating and removing residues such as oil, coolant, etc. At the same time, heating can also accelerate the chemical reaction between the cleaning agent and the oil adhering to the surface of the metal debris, thereby improving the cleaning effect and cleaning efficiency. Different types of cutting fluids / oils have different temperature sensitivities to the cleaning agent. By adjusting the temperature of the heating device 22, the cleaning agent can reach the most suitable cleaning temperature for the current metal debris, thereby ensuring the cleaning effect while avoiding unnecessary damage to the metal surface. In cold or low-temperature environments, unheated cleaning agents may become viscous or solidified, which not only affects the cleaning effect but also increases the difficulty of operation and labor costs. Heating the cleaning agent can maintain its good fluidity, making the operation smoother, while improving the working environment and increasing the comfort of employees. It should be noted that the ultrasonic cleaning module 2 includes a cleaning agent, an ultrasonic device 21 and a heating device 22.

[0029] Preferably, the spray module 3 includes a first spray device 31 and a second spray device 32 , and the first spray device 31 and the second spray device 32 are arranged on the surface of the housing 1 at intervals.

[0030] Preferably, the first spray device 31 includes a water tank 311, a solenoid valve 312 and a spray head 313. The water tank 311 is used to store flushing water. The solenoid valve 312 is connected to the water tank 311 and the spray head 313 through pipes respectively. The second spray device 32 has the same structural composition as the first spray device 31.

[0031] In this embodiment, the two spray devices are set at intervals to form a cross-spraying effect, so that the cleaned metal debris is impacted by water flow from different directions during movement. This multi-angle, multi-directional flushing method can more comprehensively remove residues on the surface of the metal debris, including fine particles, oil stains, etc., thereby enhancing the flushing effect; the two spray devices are set at intervals to make the equipment more flexible in layout, and the position and angle of the spray device can be adjusted according to actual production needs to meet the flushing needs of metal debris of different shapes, sizes and materials. This flexibility helps to improve the adaptability and versatility of the equipment; through the alternating flushing and complementary effects of the two spray devices, it can be ensured that every corner of the metal debris surface is fully flushed and cleaned. This comprehensive cleaning method helps to improve the cleaning quality and reduce secondary pollution or product quality problems caused by incomplete cleaning.

[0032] It should be noted that the metal chips that have been ultrasonically cleaned are transported out of the ultrasonic cleaning tank 13 through the conveying module and enter the spraying area of the first spray device 31. The spraying area is provided with multiple upper and lower clean water spray heads, which can simultaneously flush the metal chips from both the upper and lower directions, and flush out the cleaning agent brought out of the cleaning tank and the oil stains wrapped by the cleaning agent attached to the surface of the metal chips. Impurities such as the cleaning agent are washed away and separated. After the metal chips leave the spraying area of the first spray device 31, they enter the spraying area of the second spray device 32 and are sprayed up and down again to remove the cleaning agent, impurities and oil stains still remaining on the surface of the metal chips to the maximum extent.

[0033] Preferably, the conveying module includes a circulating conveyor belt, a rotating shaft and a driving motor, and the driving motor drives the circulating conveyor belt through the rotating shaft.

[0034] In this embodiment, the driving motor drives the rotating shaft to rotate, thereby driving the circulating conveyor belt to run continuously and stably. This design ensures the continuous conveying of metal debris during the cleaning process, avoiding the decline in cleaning effect or equipment damage due to interruption or jamming; the automated operation of the conveying module reduces the need for manual intervention, reduces labor costs, and improves production efficiency. The operator only needs to place the metal debris to be cleaned at the starting position of the circulating conveyor belt, and the equipment can automatically complete the subsequent conveying and cleaning process; the design of the circulating conveyor belt enables it to adapt to metal debris of different shapes, sizes and weights. Whether it is fine metal particles or larger metal fragments, stable conveying can be achieved by adjusting the speed and tension of the circulating conveyor belt.

[0035] It should be noted that in order to achieve better cleaning effects, the metal chips can be fully mixed with the mixture of water and cleaning agent in the cleaning tank under the action of ultrasonic vibration to achieve the maximum contact area. The circulating conveyor belt adopts a dense mesh belt structure, which is also conducive to being fully flushed from the top and bottom by clean water in the spray chamber; in addition, the circulating conveyor belt is installed with a scraper to scrape out the mud, debris and other impurities deposited at the bottom of the equipment from the bottom of the feed port, reducing the number of equipment shutdowns, emptying, cleaning and maintenance, improving equipment utilization and improving overall efficiency; at the same time, it can also achieve the goal of further reducing sewage discharge, reducing degreasing agent and clean water consumption, and further saving energy and reducing emissions.

[0036] Preferably, a power brush 16 is provided at the bottom of the discharge port 15 .

[0037] In this embodiment, the powered brush 16 can further scrub and clean the metal debris as it passes through the discharge port 15. This physical scrubbing action can remove tiny particles, oil stains or water stains remaining on the surface of the metal debris, thereby enhancing the overall cleaning effect and ensuring that the metal debris reaches a higher cleanliness standard when leaving the equipment; by providing the powered brush 16, the residue of metal debris at the discharge port can be effectively reduced. If these residues are not removed in time, they may contaminate subsequent processing processes or affect the normal operation of the equipment. The scrubbing action of the powered brush 16 can ensure that the metal debris is thoroughly removed and the accumulation of residues is reduced; as a component of the discharge port, the powered brush 16 is relatively easy to maintain and replace. When the brush is worn or damaged, it can be easily replaced to ensure the continued stable operation of the equipment. At the same time, the cleaning work of the powered brush 16 is also relatively simple and can be done by flushing or wiping.

[0038] Preferably, an industrial fan 4 is further provided on the housing 1, and the industrial fan 4 is used to dry the metal scraps after the flushing process.

[0039] In this embodiment, the industrial fan 4 can quickly blow away the moisture on the surface of the metal scraps by generating a strong airflow, accelerating the drying process. This helps reduce the problems of rust, mildew, etc. caused by residual moisture in the metal scraps during subsequent processing or storage, thereby improving storage stability. By promptly drying the moisture on the surface of the metal scraps, the drying time can be shortened, allowing the metal scraps to enter the next process or be stored more quickly, which helps improve the operating efficiency of the entire production line and reduce the time wasted waiting for drying. It should be noted that a through hole is provided on the housing, and the industrial fan 4 is connected to the through hole by a hose. The airflow of the industrial fan 4 is then transported into the housing 1 to achieve the effect of drying the moisture. The method of connecting the through hole and the hose is not shown in the figure.

[0040] Preferably, the equipment further comprises a circulating liquid tank 5 and a water pump 6, wherein the circulating liquid tank 5 is connected to the water pump 6 and the ultrasonic cleaning pool 13 through pipelines, and the water pump 6 is connected to the ultrasonic cleaning pool 13 through pipelines.

[0041] In this embodiment, the design of the circulating liquid tank 5 allows the cleaning liquid used in the cleaning process to be recycled and reused. The cleaning liquid in the cleaning pool is pumped into the circulating liquid tank 5 by the water pump 6, and after filtering, sedimentation and other treatments, it is sent back to the ultrasonic cleaning pool 13 through a pipeline for the next round of cleaning. This recycling method not only reduces the consumption of water resources, but also reduces the waste and cost of cleaning liquid; after the cleaning liquid in the circulating liquid tank 5 is treated, impurities and suspended matter can be removed, so that the cleaning liquid remains clean and efficient, which helps to keep the cleaning liquid in the ultrasonic cleaning pool 13 in the best condition at all times, thereby ensuring the consistency and stability of the cleaning effect; by recycling the cleaning liquid, the discharge and pollution of wastewater can be reduced, and the harmful substances in the cleaning liquid are controlled and treated during the circulation process, reducing the negative impact on the environment.

[0042] It should be noted that a timer can be set to discharge the turbid cleaning liquid in the ultrasonic cleaning tank 13 to the off-line circulating liquid tank 5. After the solid impurities in the cleaning liquid are naturally precipitated and filtered, the clean cleaning liquid will be automatically re-pumped into the cleaning tank to achieve the purpose of recycling. In addition, general ultrasonic cleaning equipment consumes a lot of degreasing agents and clean water, and discharges a lot of wastewater. The utility model realizes the functions of internal water circulation and cleaning liquid circulation, reduces water consumption, reduces the consumption of cleaning agents, protects water resources, reduces costs, and reduces wastewater discharge.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
