Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, specifically to an intelligent integrated device for collecting metal processing waste and filtering oil mist. Background Technology

[0002] Metalworking fluids play a crucial role in metal processing. They not only flush, lubricate, and dissipate heat from machined parts, but also provide excellent cooling, cleaning, and rust prevention. Cutting fluids are typically formulated with a scientific blend of various high-performance additives to ensure their superior performance in metalworking.

[0003] However, despite the numerous technological advantages offered by cutting fluids, they also pose potential risks to operator health and the working environment. Direct skin contact with cutting fluids or inhalation of their aerosols can cause respiratory illnesses and skin inflammation. To address these issues, modern metalworking equipment is typically equipped with protective shields to enclose the machining process, and operators wear comprehensive personal protective equipment to minimize the risk of direct contact. Nevertheless, some problems remain unresolved in practice. For example, metal shavings generated during machining are carried by the cutting fluid to a trolley below the equipment's scrap outlet. Residual fluid in this scrap flows into an oil collection basin through a drain valve beneath the trolley. Because both the scrap discharge process and the oil collection basin are exposed to the air without any shielding, oil mist particles from the waste fluid escape into the upper part of the plant, forming floating oil mist. This not only reduces the plant's air permeability but also affects its air quality. Utility Model Content

[0004] The present invention aims to provide an intelligent integrated device for collecting metal processing waste and filtering oil mist, so as to treat the waste discharged from metal processing and prevent the residual waste liquid in the waste from directly escaping into the air and accumulating in the upper space of the factory, reducing the air permeability of the factory and affecting the air quality of the factory.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an intelligent integrated device for collecting metal processing waste and filtering oil mist, comprising a waste collection mechanism, the waste collection mechanism comprising a device body and a demisting unit, the device body being fixed with a connector for sealing the waste outlet of the metal processing equipment, the demisting unit comprising a spray assembly and a control assembly, the spray assembly comprising a plurality of nozzles, the nozzles being fixed on the inner wall of the connector and connected to a solution for accelerating oil mist settling, the control assembly comprising a controller, the controller being connected to the nozzles and capable of controlling the nozzles to spray the solution.

[0006] The beneficial effects of this solution are as follows: 1. This solution uses a connector on the main body of the device to seal the waste discharge port of the metal processing equipment, thereby preventing residual waste liquid in the waste from directly escaping into the air and affecting air quality; 2. This solution uses a spray component installed on the inner wall of the connector to spray a solution inside the connector to accelerate oil mist settling, thereby preventing the oil mist concentration inside the connector from being too high, causing the oil mist to overflow from the connector's shield and escape into the air, affecting air quality; 3. The controller controls the opening and closing of the nozzles, so that the spray component sprays the solution only when needed, reducing solution loss and the amount of waste liquid.

[0007] Furthermore, the control component also includes a detector, which is installed on the inner wall of the connector and can detect the oil mist concentration inside the connector and input the oil mist concentration into the controller. The controller has a built-in first trigger information, and the controller controls the nozzle to open and maintain it for a first set time based on the oil mist concentration input by the detector and the first trigger information.

[0008] Beneficial effects: The detector detects the oil mist concentration inside the connector and controls the nozzle to open based on the oil mist concentration. This causes the volatile oil mist to settle and collect inside the device under the action of the spray, keeping the oil mist inside the connector within a low concentration range. This prevents the oil mist concentration inside the connector from becoming too high and allows the oil mist to escape through the sealed connector, ensuring that the residual waste liquid in the waste material cannot enter the air through oil mist.

[0009] Furthermore, the first trigger information includes a warning concentration value and a first set time. When the concentration information input to the controller from the detector is greater than or equal to the warning concentration value, the controller controls the nozzle to open and maintain the first set time. By setting the warning value and the first set time, when the oil mist in the connector triggers the warning value, the nozzle will open and maintain the first set time, keeping the oil mist concentration in the connector within a low range. This prevents the oil mist concentration in the connector from remaining at a high level for a long time, which would cause the oil mist to escape into the air and affect air quality.

[0010] Furthermore, the controller also has a built-in second trigger information and can control the nozzle to open based on this second trigger information. The second trigger information defines a periodic trigger mode that includes a first set time and a second set time. When the controller is powered on and the second set time has elapsed, the controller controls the nozzle to open and maintain the first set time. Then the nozzle closes, the controller restarts the timing, and the process repeats after the second set time has elapsed again, forming a continuous periodic operation mode. When the oil mist concentration inside the connector remains slightly below the warning value for a long time, the first trigger information cannot control the nozzle to open and settle the oil mist inside the connector. Due to the strong penetrability of the cutting fluid, when the oil mist floats inside the connector for a long time, it may escape into the air through the gaps in the connector. By setting the second trigger information, even if the oil mist inside the connector remains at a low level for a long time, a solution for settling the oil mist can be sprayed periodically, causing the oil mist inside the connector to settle into waste oil, thereby preventing the oil mist from escaping into the air and affecting air quality.

[0011] Furthermore, after the controller activates the nozzle based on the first trigger information and maintains it for a first set time, the second set time of the second trigger information is reset. Linking the first and second trigger information together reduces solution loss and waste liquid generation.

[0012] Furthermore, the connector is equipped with an exhaust port, on which a filter screen and a negative pressure generator are sequentially fixed. By providing an exhaust port on the connector, and installing a filter screen and a negative pressure generator on the exhaust port, the airflow inside the connector passes through the filter screen and is discharged through the exhaust port. This controls the movement trajectory of the oil mist inside the connector through airflow, preventing the oil mist from overflowing from the gaps in the connector.

[0013] Furthermore, the filter screen includes a first filter screen and a second filter screen. The pore size of the first filter screen is smaller than the particle size of the oil mist and larger than the pore size of the second filter screen. The first and second filter screens are sequentially fixedly installed on the exhaust port. By setting the first and second filter screens, the airflow in the connector passes through the first and second filter screens sequentially before being discharged from the exhaust port. This causes the oil mist to accumulate and coalesce into waste oil at the first and second filter screens, preventing the oil mist from overflowing through the gaps in the connector. At the same time, the dual filtration of the first and second filter screens makes the gas discharged through the exhaust port cleaner, preventing the exhaust from affecting air quality.

[0014] Furthermore, the device body also includes a trolley and an oil collection assembly. The trolley includes a bucket with a handle fixed to it. A movable component is rotatably mounted below the bucket. The bottom of the inner side of the bucket is an inclined surface. The oil collection assembly includes an oil drain valve, a plate frame, and an oil pan. The oil drain valve and the plate frame are both fixedly mounted at the lower part of the bucket and located on the lower end of the inclined surface. The oil pan rests on the plate frame and can collect the waste oil discharged from the oil drain valve. By making the bottom of the inner side of the bucket an inclined surface and placing the oil drain valve and oil pan at the lower part of the bucket on the lower end of the inclined surface, the waste oil accumulated in the bucket can be collected on the side of the oil drain valve through the inclined surface, thus facilitating the discharge of the waste oil accumulated in the bucket through the oil drain valve. At the same time, by fixing the plate frame at the lower part of the bucket, the distance between the oil pan and the oil drain valve is shortened, avoiding the splashing of waste oil and environmental pollution during the oil discharge process.

[0015] Furthermore, the movable component is a wheel, and the wheel is equipped with a fixing buckle that can restrict the rotation of the wheel.

[0016] Furthermore, a baffle plate is placed inside the truck bed, with several filter holes to filter the waste oil that settles into oil mist. The baffle plate is inclined inside the truck bed and tilts towards the spray assembly, while the bottom of the truck bed tilts away from the spray assembly. This tilt creates a waste oil storage cavity between the baffle plate and the bottom of the truck bed, isolating the waste material from the waste oil and preventing oil from soaking the waste material, thus avoiding residual waste oil that could affect subsequent waste treatment. Simultaneously, by setting the baffle plate towards the spray assembly, the contact area between the solution sprayed by the spray assembly and the waste material is increased, allowing the solution sprayed by the spray assembly to periodically clean the waste material, thereby reducing the difficulty of subsequent waste treatment.

[0022] The following detailed description illustrates the specific implementation methods:

[0023] The reference numerals in the accompanying drawings include: trolley 10, handle 11, tray frame 12, oil drain valve 13, oil pan 14, connector 21, exhaust port 211, spray assembly 22, first filter screen 231, second filter screen 232, negative pressure generator 233, oil mist concentration detector 24, and waste discharge port 30.

[0024] Example 1

[0025] Example 1 is basically as shown in the appendix. Figure 1-4 As shown, Figure 1-4 The device shown is an intelligent integrated collection and oil mist filtration device for metal processing waste, used for oil mist prevention at the waste outlet 30 of metal processing equipment. It includes the device body and a filtration and demisting mechanism, such as... Figure 1 , Figure 4 As shown, the device body includes a trolley 10, a connector 21, and an oil collection assembly. The connector 21 is located between the waste discharge port 30 and the trolley 10 and is fixedly connected to the top of the trolley 10 and the waste discharge port 30 respectively, thereby ensuring the airtightness between the waste discharge port 30 and the trolley 10. The trolley 10 includes a bucket, and wheels are rotatably mounted on the lower surface of the bucket. Fixed buckles are mounted on the wheels and can restrict the rotation of the wheels by engaging with the bucket. Handrails 11 are fixed to the side wall of the bucket. In use, the operator can use the handrails 11 and the wheels to push the bucket below the waste discharge port 30 and fix the bucket by restricting the rotation of the wheels. The waste discharge port 30 is connected to the bucket using the connector 21. At the same time, after the metal processing is completed, the trolley 10 and the waste collected in the trolley 10 can also be transferred to the subsequent processing site using the handrails 11.

[0026] The connector 21 is provided with an exhaust port 211. In this embodiment, the connector 21 is a soft curtain. The soft curtain is made of opaque, magnetic, self-adhesive PVC material. In use, the soft curtain is wrapped around the waste outlet, so that the upper and lower ends of the soft curtain respectively surround the waste outlet 30 and the hopper. The left and right ends of the soft curtain are attracted together by the magnetism of the soft curtain itself, forming a shape like... Figure 2 The diagram shows a closed cylindrical structure.

[0027] The oil collection assembly includes an oil drain valve 13, a tray 12, and an oil pan 14. The oil drain valve 13 is welded to the side wall of the truck bed and is connected to the inside of the truck bed. The tray 12 is welded to the bottom of the truck bed. When in use, the oil pan 14 is placed on the tray 12 and the oil drain valve 13 is opened, so that the waste oil accumulated in the truck bed is drained into the oil pan 14 through the oil drain valve 13.

[0028] The filtration and demisting mechanism includes a filtration unit and a demisting unit. The filtration unit includes a first filter screen 231, a second filter screen 232, and a negative pressure generator 233 connected in sequence. The pore sizes of the first filter screen 231 and the second filter screen 232 decrease sequentially and are both smaller than the particle size of the oil mist. Both the first filter screen 231 and the second filter screen 232 are welded to the inner wall of the truck bed. The negative pressure generator is adhered to the inner wall around the exhaust port 211 and connected to the second filter screen 232 through a connecting pipe. In use, if... Figure 4 As shown, the negative pressure generator 233 is used to discharge the gas in the truck bed and the connecting part 21, so that the gas in the truck bed and the connecting part 21 passes through the first filter screen 231 and the second filter screen 232 in sequence, and is discharged through the exhaust port 211. Thus, the oil mist in the waste is filtered out by the first filter screen 231 and the second filter screen 232, so that the air discharged to the outside does not contain oil mist, thereby improving the outdoor air quality.

[0029] The demisting unit includes a spray assembly 22 and a control assembly. The spray assembly 22 includes several nozzles, which are connected to a solution for accelerating oil mist settling. A solenoid valve and a pipeline pump are installed between the solution and the nozzles, so that the solution is evenly sprayed out through the nozzles using the solenoid valve and the pipeline pump, so that the oil mist in the connector 21 is deposited at the bottom of the truck bed, avoiding excessive oil mist concentration in the connector 21, which would cause oil mist to seep out from the gaps in the connector 21 and pollute the environment.

[0030] The control component includes a controller and several oil mist concentration detectors 24. The controller has built-in first trigger information, which includes a warning concentration value and a first set time. The controller is electrically connected to the oil mist concentration detectors 24, solenoid valves, and pipeline pumps. When the concentration value input to the controller by the concentration detectors is greater than the warning concentration value, the controller controls the solenoid valves and pipeline pumps to start and maintain the first set time. In this embodiment, the oil mist concentration detectors 24 are divided into two groups, with the two groups of oil mist concentration detectors 24 respectively positioned above and below the connector 21. Figure 3 As shown, in this embodiment, there are six oil mist concentration detectors 24 in each group, and the six oil mist concentration detectors 24 are evenly fixed on the inner walls on both sides of the connector 21.

[0031] When the oil mist concentration detector 24 detects that the concentration is greater than the warning concentration value, the controller controls the pipeline pump and solenoid valve to open, so that the solution is sprayed out from the nozzle and the oil mist in the connector 21 settles to form waste oil. When a certain amount of waste oil has accumulated, or when it is necessary to clean the waste in the truck bed, the waste oil accumulated in the truck bed can be discharged into the oil pan 14 through the oil drain valve 13.

[0032] In this embodiment, the logic for the controller to determine the concentration value input by the oil mist concentration detector 24 is as follows:

[0033] The controller obtains first concentration data and second concentration data through the concentration value data input by the oil mist concentration detector 24. The first concentration data is the average value of the input values ​​of the concentration detector in this group, and the second concentration data is the average value after excluding the maximum and minimum values ​​of each group of concentration values. When the difference between the first data and the second data is less than the error value and both are greater than the warning concentration value, the controller controls the pipeline pump and solenoid valve to open and maintain for a first set time, so that the solution is sprayed out from the nozzle and the oil mist in the connector 21 settles to form waste oil. When the difference between the first data and the second data is greater than or equal to the error value, and the second concentration data is greater than or equal to the warning concentration value, the controller controls the pipeline pump and solenoid valve to open and maintain for a first set time, so that the solution is sprayed out from the nozzle and the oil mist in the connector 21 settles to form waste oil.

[0034] Example 2

[0035] Example 2 is basically the same as Example 1, except that, as Figure 5 As shown, a partition is placed inside the truck bed, and the partition has several filter holes. The diameter of the filter holes is larger than the diameter of the first filter screen 231 but smaller than the particle size of the waste. The partition is inclined towards the spray assembly 22, and the bottom of the truck bed is inclined away from the spray assembly 22, forming a waste oil storage cavity between the bottom of the partition and the bottom of the truck bed. This isolates the waste from the waste oil, preventing the oil from soaking the waste and leaving some waste oil residue, which would affect subsequent waste treatment. At the same time, by setting the partition inclined towards the spray assembly 22, the contact area between the solution sprayed by the spray assembly 22 and the waste is increased, thereby facilitating the cleaning of the waste by the solution sprayed by the spray assembly 22 and reducing the difficulty of subsequent waste treatment.

[0036] Meanwhile, the controller also has a built-in second trigger information, which is a periodic triggering mode including a first set time and a second set time. The first set time is the same as the time during which the solenoid valve is opened and maintained in the first trigger information. The control flow of the second trigger information is as follows: S1 When the device is powered on and the second set time is reached, the controller controls the solenoid valve and pipeline pump to start and maintain the first set time to spray the solution into the connector 21; S2 Repeat S1 until the metal processing is completed or the power is cut off. This is to avoid the spray assembly 22 failing to trigger due to the oil mist in the connector 21 not reaching the warning concentration value for a long time or the concentration detector malfunctioning, causing the low concentration oil mist in the connector 21 to overflow from the shield of the connector 21 and affect the air quality in the factory.

[0037] Example 3

[0038] Based on Example 2, the difference is that when the first trigger information is triggered, the second set time of the second trigger information is reset, thereby avoiding continuous triggering of the spray and reducing solution loss.
