Description

Technical Field

[0001] This utility model relates to the technical field of atomized spraying equipment, and in particular to an atomized spraying device with oil and gas recovery function. Background Technology

[0002] In fields such as machinery manufacturing and automotive parts processing, workpiece surfaces often require the application of rust-preventive grease to form a protective layer and prevent corrosion. Traditional spraying methods mostly employ open or semi-open operations, where the rust-preventive grease is atomized and sprayed onto the workpiece surface. However, this process easily generates oily mist (referred to as "oil vapor"). This oil vapor not only wastes grease but also diffuses into the working environment, polluting the air, affecting the health of operators, and posing a flammable safety hazard. Therefore, there is an urgent need for an atomized spraying device with oil vapor recovery capabilities to solve the above problems. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model provides an atomizing spraying device with oil and gas recovery function, which solves the technical problem that after the workpiece is sprayed, oil and gas will diffuse into the working environment, polluting the air and affecting the health of operators.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: An atomizing spraying device with oil and gas recovery function is used to spray rust-preventive grease onto a preset position on the surface of a workpiece and recover waste oil and gas after spraying, comprising: Atomizing spraying assembly includes: a base plate and a cover, the cover being sealed on the base plate, the base plate having a support for placing workpieces, the cover having a set of spray valve assemblies spaced apart along the circumference of the support, and the base plate having an oil inlet and an oil outlet on the side away from the support, the oil inlet being connected to the set of spray valve assemblies respectively. The oil supply assembly includes: an oil supply tank and an oil supply pump, wherein the oil supply pump is mounted on the oil supply tank and is connected to the oil inlet; An oil and gas recovery assembly includes: a vacuum tank, a recovery oil tank, and a vacuum extraction device. The vacuum tank is equipped with: an oil inlet connector and a waste oil outlet. The oil inlet connector is connected to the oil outlet, the waste oil outlet is connected to the recovery oil tank, and the vacuum extraction device is connected to the vacuum tank.

[0005] Based on the above structure, the principle of the atomizing spraying device with oil and gas recovery function is as follows: In use, firstly, the workpiece to be sprayed is placed on the carrier, and the position of a set of spray valve assemblies is adjusted so that the nozzles of the spray valve assemblies are all aligned with the spraying position of the workpiece. The cover is closed to ensure a complete seal between the cover and the base plate, preventing oil and gas leakage from the gap between the base plate and the cover during spraying. Then, the oil supply pump is started, and the pressure of the oil supply pump is adjusted so that the rust-preventive grease is delivered to the set of spray valve assemblies through the oil inlet, and the workpiece is sprayed. After the rust-preventive grease is sprayed, the vacuum extraction device is started to create a negative pressure inside the vacuum tank. The waste oil and gas inside the cover are sucked into the vacuum tank through the oil outlet and the oil inlet connector, where the waste oil and gas settle. Then, after the vacuum extraction device is closed, the liquid waste oil in the vacuum tank flows into the recovery oil tank through the waste oil outlet. Finally, the cover is opened, and the sprayed workpiece is removed from the carrier, completing the workpiece spraying process.

[0006] Furthermore, in this application, an atomizing spraying device with oil and gas recovery function is provided, wherein the housing has a side opening, and a sealed door is rotatably installed at the side opening of the housing, and the sealed door has an inspection port. As a preferred embodiment of this application, the atomizing spraying device with oil and gas recovery function of this application has a side opening on the housing as a channel for workpieces to enter and exit the housing, facilitating the loading and unloading of workpieces; the sealed door ensures that a closed space is formed inside the housing, which not only effectively prevents external dust and impurities from entering and maintains a clean environment inside the housing, but also prevents oil and gas from leaking out of the housing from the side opening during oil and gas recovery; the inspection port allows the operator to observe the spraying status of the workpiece surface and the working status of the spray valve assembly in real time without opening the sealed door.

[0007] Furthermore, in this application, an atomizing spraying device with oil and gas recovery function is provided. The outer wall of the cover near the bottom plate has an edge extending circumferentially along the cover. The bottom plate near the cover has a groove adapted to the edge, which accommodates the edge. A sealing ring is provided within the groove. When the cover is placed on the bottom plate, the two sides of the sealing ring respectively fit against the bottom walls of the edge and the groove. As a preferred embodiment of this application, when the cover is closed, the edge embeds into the groove and compresses the sealing ring, causing the two sides of the sealing ring to fit tightly against the bottom walls of the edge and the groove, forming a sealing surface. This prevents external dust and impurities from seeping in or internal oil and gas from leaking out during workpiece spraying and oil and gas recovery. The fit between the edge and the groove has a guiding function, allowing for positioning during cover installation and improving assembly efficiency.

[0008] Furthermore, in this application, an atomizing spraying device with oil and gas recovery function is provided, wherein the housing is further provided with a set of adjustable brackets, each set of adjustable brackets corresponding to a set of spray valve assemblies. Each adjustable bracket includes an adjusting rod, a movable block on the adjusting rod, the movable block being movably adjustable along the axial direction of the adjusting rod, and a mounting block rotatably adjustable on the movable block. The spray valve assembly is mounted on the mounting block. As a preferred embodiment of this application, the adjustable brackets in the atomizing spraying device with oil and gas recovery function improve the versatility of the atomizing spraying device. Operators can adjust the position of the movable block on the adjusting rod and the rotation angle of the mounting block to adapt to workpieces of different sizes and shapes. Moreover, each adjustable bracket can be adjusted independently, allowing operators to adjust parameters for individual spray valve assemblies, reducing adjustment difficulty and improving atomizing spraying quality.

[0009] Furthermore, in an atomizing spraying device with oil and gas recovery function, the base plate near the cover is provided with an oil collection trough, which is connected to an oil outlet. As a preferred embodiment of this application, in the atomizing spraying device with oil and gas recovery function, during the atomizing spraying process, the oil collection trough is used to guide and collect the rust-preventive grease that condenses into liquid oil droplets, which then flows out of the cover through the oil outlet and enters the oil and gas recovery component for processing.

[0010] Furthermore, in this application, an atomizing spraying device with oil and gas recovery function is provided. The oil and gas recovery component further includes a filter. The vacuum tank is provided with an air connector. The air inlet and outlet of the filter are respectively connected to the air connector and the vacuum extraction device. The bottom of the filter is provided with a waste liquid outlet, which is connected to the recovery oil tank. As a preferred embodiment of this application, in this atomizing spraying device with oil and gas recovery function, the filter is connected in series between the vacuum tank and the vacuum extraction device to filter and intercept tiny oil droplets and oil and gas, preventing them from entering and contaminating or damaging the vacuum extraction device, thereby improving the service life of the vacuum extraction device and reducing maintenance costs. Air containing oil and gas is intercepted and condensed in the filter and discharged into the recovery oil tank through the waste liquid outlet.

[0011] Furthermore, in an atomizing spraying device with oil and gas recovery function, a pressure regulating valve is provided between the oil supply pump and the oil inlet, with the inlet and outlet of the pressure regulating valve connected to the oil supply pump and the oil inlet, respectively. As a preferred embodiment of this application, the pressure regulating valve is connected in series between the oil supply pump and the oil inlet to ensure a stable supply pressure of the rust-preventive grease during the atomizing spraying process, ensuring uniform atomization and consistent spraying of the rust-preventive grease, improving the consistency of workpiece spraying, and also preventing pressure fluctuations from damaging the spray valve assembly.

[0012] Furthermore, in this application, an atomizing spraying device with oil and gas recovery function is provided, wherein both the oil supply tank and the recovery tank are equipped with level sight glasses on their side walls. These sight glasses are used to observe the liquid level within the tanks. As a preferred embodiment of this application, the design of the level sight glasses in this atomizing spraying device with oil and gas recovery function allows operators to directly check the liquid level within the tanks, preventing oil supply interruption and spraying cessation due to oil depletion in the oil supply tank, or preventing overflow problems caused by excessive waste oil in the recovery tank.

[0013] Furthermore, in this application, an atomizing spraying device with oil and gas recovery function is provided, wherein the bottom of the recovery oil tank is provided with an oil discharge port, which is connected to the inside of the recovery oil tank. As a preferred embodiment of this application, in this atomizing spraying device with oil and gas recovery function, the oil discharge port is used to discharge the collected waste oil from the recovery oil tank, using gravity to achieve complete and rapid discharge of waste oil and avoid residue.

[0014] As can be seen from the above technical solution, this utility model has the following beneficial effects: The purpose of this invention is to provide an atomizing spraying device with oil and gas recovery function. By setting a cover with a side opening, a rotatable airtight door, and an inspection port, combined with a groove on the base plate that fits the edge of the cover, and an internal sealing ring, a reliable seal between the cover and the base plate is achieved. This facilitates workpiece loading and unloading while preventing oil and gas leakage and external dust infiltration, and also allows for real-time observation of the spraying process. A set of adjustable brackets corresponding one-to-one with the spray valve assembly allows for adjustment of the position and angle of the spray valve assembly, adapting to workpieces of different sizes and shapes, thus improving the device's versatility. A pressure-stabilizing valve connected in series between the oil pump and the oil inlet ensures a stable supply pressure of the anti-rust grease, ensuring uniform spraying and preventing pressure fluctuations from damaging the spray valve. The system utilizes a filter connected in series between the vacuum tank and the vacuum extraction device within the oil and gas recovery assembly to intercept minute oil droplets and oil vapors, protecting the vacuum extraction device and discharging condensed waste liquid into the recovery tank. This, combined with an oil collection trough connected to the oil outlet on the bottom plate to collect liquid oil droplets, and an oil discharge port at the bottom of the recovery tank, ensures rapid and thorough discharge of waste oil. Level sight glasses installed on the side walls of the oil supply tank and recovery tank facilitate direct monitoring of the tank levels, preventing oil supply interruptions or waste oil overflows. Ultimately, it enables precise spraying of anti-rust grease onto preset positions on the workpiece surface, and efficiently recovers waste oil and gas after spraying, reducing environmental pollution, preventing operator inhalation, protecting personnel health, and improving the ease of operation, stability, and service life of the device.

[0018] Based on the above structure, the principle of the atomizing spraying device with oil and gas recovery function is as follows: In use, firstly, the workpiece to be sprayed is placed on the carrier 2, and the position of a set of spray valve assemblies 3 is adjusted so that all nozzles of the set of spray valve assemblies 3 are aligned with the spraying position of the workpiece. The cover 12 is closed to ensure a complete seal between the cover 12 and the base plate 11, preventing oil and gas leakage from the gap between the base plate 11 and the cover 12 during spraying. Then, the oil supply pump 42 is started, and the pressure of the oil supply pump 42 is adjusted so that the rust-preventive grease is delivered to the set of spray valve assemblies 3 through the oil inlet 110. The mist valve assembly 3 begins spraying the workpiece; after the anti-rust grease is sprayed, the vacuum extraction device 53 is activated to create a negative pressure inside the vacuum tank 51. The waste oil and gas inside the cover 12 are drawn into the vacuum tank 51 through the oil outlet 111 and the oil inlet connector 511. The waste oil and gas settle in the vacuum tank 51. Then, after the vacuum extraction device 53 is turned off, the liquid waste oil in the vacuum tank 51 flows into the recovery oil tank 52 through the waste oil outlet 512. Finally, the cover 12 is opened, and the sprayed workpiece is taken out from the carrier 2, completing the spraying process of the workpiece. The number of spray valve assemblies 3 is 4.
