Description

Technical Field

[0001] The invention relates to the technical field of metal processing, and in particular to an intelligent integrated device for collecting metal processing waste and filtering oil mist. Background Art

[0002] In the metal processing process, metal cutting fluid plays a vital role. It is not only used to flush, lubricate and dissipate heat for processed parts, but also has good cooling, cleaning and rust prevention properties. Cutting fluid is usually scientifically formulated with a variety of high-performance additives to ensure its excellent performance in metal processing.

[0003] However, despite the many technical advantages brought by cutting fluids, they also bring potential risks to the health of operators and the working environment. Direct skin contact with cutting fluids or inhalation of the aerosols produced by cutting fluids may cause respiratory diseases and skin inflammation. To address these problems, modern metal processing equipment is usually equipped with protective covers to enclose the processing process, and operators also wear comprehensive personal protective equipment to minimize the risk of direct contact. Despite this, in actual operation, there are still some problems that have not been fully addressed. For example, the metal chips generated during the processing are washed by the cutting fluid and carried to the cart below the waste outlet of the equipment. The waste liquid remaining in these wastes will flow into the oil collection basin through the oil discharge valve under the cart. Since the waste discharge process and the oil collection basin are exposed to the air without shielding devices, the oil mist particles in the waste liquid escape into the upper and middle space of the plant, forming floating oil mist. This not only reduces the air permeability of the plant, but also affects the air quality of the plant. Summary of the invention

[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, avoid the waste liquid remaining in the waste from directly escaping into the air and accumulating in the upper space of the factory building, thereby reducing the air permeability of the factory building and affecting the air quality of the factory building.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an intelligent integrated device for metal processing waste collection and oil mist filtration, including a waste collection mechanism, the waste collection mechanism includes a device body and a defogger unit, a connector for closing the waste outlet of the metal processing equipment is fixed on the device body, the defogger unit includes a spray assembly and a control assembly, the spray assembly includes a plurality of nozzles, the nozzles are fixed on the inner wall of the connector and are connected to a solution for accelerating the sedimentation of the oil mist, the control assembly includes a controller, the controller is connected to the nozzle and can control the nozzle to spray the solution.

[0006] The beneficial effects of this solution are as follows: 1. This solution uses a connecting piece arranged on the device body to seal the waste discharge port of the metal processing equipment, thereby preventing the waste liquid remaining in the waste from directly escaping into the air and affecting the air quality; 2. This solution uses a spray assembly arranged on the inner wall of the connecting piece to spray a solution for accelerating the sedimentation of oil mist into the connecting piece, so as to avoid excessive oil mist concentration in the connecting piece, causing the oil mist to overflow the shielding of the connecting piece and escape into the air, affecting the air quality; 3. The controller is used to control the opening or closing of the nozzle, so that the spray assembly sprays the solution only when needed, reducing the loss of solution and the amount of waste liquid.

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

[0008] Beneficial effect: The detector detects the oil mist concentration in the connector, and controls the nozzle opening according to the oil mist concentration, so that the volatilized oil mist settles and gathers in the device body under the action of the spray, so that the oil mist in the connector is maintained in a lower concentration range, thereby avoiding excessive oil mist concentration in the connector, allowing the oil mist to escape through the closure of the connector, ensuring that the waste liquid remaining in the waste cannot enter the air in the form of oil mist.

[0009] Furthermore, the first trigger information includes a warning concentration value and a first set time. When the concentration information input by the detector to the controller 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, so that the oil mist concentration in the connector is maintained in a lower range, thereby preventing the oil mist concentration in the connector from being maintained in a higher range for a long time, causing the oil mist to escape into the air and affect the air quality.

[0010] Furthermore, the controller also has a built-in second trigger information and can control the nozzle to open according to the second trigger information. The second trigger information defines a periodic trigger mode including a first set time and a second set time. When the controller is powered on and the second set time has passed, the controller controls the nozzle to open and maintain the first set time, then the nozzle is closed, and the controller restarts the timing. After the second set time has passed, the above process is repeated to form a continuous periodic operation mode. When the oil mist concentration in the connector is maintained at a state slightly lower than the warning value for a long time, the first trigger information cannot be used to control the nozzle to open and settle the oil mist in the connector. Due to the strong permeability of the cutting fluid, when the oil mist floats in the connector for a long time, the oil mist may escape into the air through the gap of the connector. Through the setting of the second trigger information, even if the oil mist in the connector is in a low state for a long time, the solution for settling the oil mist can be sprayed regularly to make the oil mist in the connector settle as waste oil, thereby preventing the oil mist from escaping into the air and affecting the quality of the air.

[0011] Furthermore, when the controller controls the nozzle to open and maintain the first set time according to the first trigger information, the second set time of the second trigger information is reset. The first trigger information and the second trigger information are linked together to reduce the loss of solution and the generation of waste liquid.

[0012] Furthermore, an exhaust port is provided on the connecting piece, and a filter screen and a negative pressure generating element are fixed to the exhaust port in sequence. By providing the exhaust port on the connecting piece, and providing the filter screen and the negative pressure generating element on the exhaust port, the airflow in the connecting piece passes through the filter screen and is discharged from the exhaust port, thereby controlling the movement trajectory of the oil mist in the connecting piece through the airflow, and preventing the oil mist from overflowing from the gap of the connecting piece.

[0013] Furthermore, the filter includes a first filter and a second filter, the aperture of the first filter is smaller than the particle size of the oil mist and larger than the aperture of the second filter, and the first filter and the second filter are fixedly arranged on the exhaust port in sequence. By arranging the first filter and the second filter, the airflow in the connecting member passes through the first filter and the second filter in sequence and then is discharged from the exhaust port, so that the oil mist gathers and aggregates into waste oil at the first filter and the second filter, and the oil mist is prevented from overflowing through the gap of the connecting member. At the same time, through the double filtration of the first filter and the second filter, the gas discharged through the exhaust port is cleaner, and the air quality is prevented from being affected by the exhaust.

[0014] Furthermore, the device body also includes a cart and an oil collection component, the cart includes a bucket, a handrail is fixed on the bucket, a movable part is rotatably arranged under the bucket, the bottom of the inner side of the bucket is an inclined surface, and the oil collection component includes an oil drain valve, a disc rack and an oil pan, the oil drain valve and the disc rack are fixedly arranged at the lower part of the bucket and located on the low end side of the inclined surface, the oil pan is placed on the disc rack and can collect the waste oil discharged by the oil drain valve. The bottom surface of the inner side of the bucket is set as an inclined surface, and the oil drain valve and the oil pan are arranged at the lower part of the bucket on the low end side of the inclined surface, the waste oil accumulated in the bucket can be gathered on the side of the oil drain valve through the inclined surface, so that the waste oil accumulated in the bucket can be discharged through the oil drain valve. At the same time, by fixing the disc rack at the lower part of the bucket, the distance between the oil pan and the oil drain valve is shortened, so as to avoid the waste oil splashing and polluting the environment during the process of discharging oil through the oil drain valve.

[0015] Furthermore, the moving part is a wheel, and the wheel is provided with a fixing buckle capable of limiting the rotation of the wheel.

[0016] Furthermore, a partition is placed in the truck bed, and a plurality of filter holes are arranged on the partition to filter the waste oil settled by the oil mist. The partition is tilted in the truck bed and tilted toward the spray assembly side, and the bottom of the truck bed tilts away from the spray assembly side, so that a waste oil storage cavity is formed between the bottom of the partition and the bottom of the truck bed, which isolates the waste material from the waste oil, and prevents the waste material from being soaked by the oil, so that some waste oil remains in the waste material, affecting the subsequent waste material treatment; at the same time, by setting the partition tilted toward the spray assembly side, the contact area between the solution sprayed by the spray assembly and the waste material is increased, so that the solution sprayed by the spray assembly can be used to regularly clean the waste material, thereby reducing the difficulty of subsequent waste material treatment.

[0022] The following is further described in detail through specific implementation methods:

[0023] The figure marks in the drawings of the specification include: a cart 10, an armrest 11, a tray rack 12, an oil drain valve 13, an oil pan 14, a connecting piece 21, an exhaust port 211, a spray assembly 22, a first filter 231, a second filter 232, a negative pressure generating element 233, an oil mist concentration detector 24, and a waste material discharge port 30.

[0024] Example 1

[0025] Embodiment 1 is basically as attached Figure 1-4 As shown, Figure 1-4 The intelligent metal processing waste collection and oil mist filtering integrated device shown is used for the oil mist prevention work of the waste outlet 30 of the metal processing equipment, including the device body and the filtering and demisting mechanism, such as Figure 1 , Figure 4 As shown, the device body includes a cart 10, a connecting piece 21 and an oil collection assembly. The connecting piece 21 is arranged between the waste discharge port 30 and the cart 10 and is fixedly connected to the top of the cart 10 and the waste discharge port 30 respectively, so as to ensure the airtightness between the waste discharge port 30 and the cart 10. The cart 10 includes a bucket. A wheel is rotatably arranged on the lower surface of the bucket. A fixed buckle is arranged on the wheel. The fixed buckle is rotatably arranged on the wheel and can limit the rotation of the wheel by engaging with the bucket. A handrail 11 is fixed to the side wall of the bucket. When in use, the operator can push the bucket to the bottom of the waste discharge port 30 with the help of the handrail 11 and the wheel, and limit the rotation of the wheel by the fixed buckle, so as to fix the bucket, and connect the waste discharge port 30 to the bucket by using the connecting piece 21. At the same time, after the metal processing is completed, the handrail 11 can also be used to transfer the cart 10 and the waste collected in the cart 10 to a subsequent processing site.

[0026] The connecting member 21 is provided with an exhaust port 211. In this embodiment, the connecting member 21 is a soft curtain, which is made of a light-proof magnetic self-absorbing PVC material. When in use, the soft curtain is placed around the waste outlet so that the upper and lower ends of the soft curtain surround the waste outlet 30 and the truck bucket respectively, and the left and right ends of the soft curtain are adsorbed together by the magnetic properties of the soft curtain itself, forming a vacuum cleaner. Figure 2 A closed cylindrical structure is shown.

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

[0028] The filtering and demisting mechanism includes a filtering unit and a demisting unit. The filtering unit includes a first filter screen 231, a second filter screen 232 and a negative pressure generating element 233 which are connected in sequence. The apertures of the first filter screen 231 and the second filter screen 232 are successively reduced and are both smaller than the particle size of the oil mist. The first filter screen 231 and the second filter screen 232 are both welded to the inner wall of the truck bucket. The negative pressure generating unit is bonded to the inner wall around the exhaust port 211 and is connected to the second filter screen 232 through a connecting pipe. When in use, Figure 4 As shown, the negative pressure generating element 233 is used to discharge the gas in the truck bed and the connecting piece 21, so that the gas in the truck bed and the connecting piece 21 passes through the first filter 231 and the second filter 232 in sequence and is discharged through the exhaust port 211, thereby filtering out the oil mist in the waste through the first filter 231 and the second filter 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 a plurality of nozzles. The nozzles are connected to a solution for accelerating the sedimentation of oil mist. An electromagnetic valve and a pipeline pump are arranged between the solution and the nozzles. The electromagnetic valve and the pipeline pump are used to evenly spray the solution through the nozzles, so that the oil mist in the connecting piece 21 is deposited to the bottom of the truck bed, thereby avoiding excessive concentration of oil mist in the connecting piece 21, which causes the oil mist to seep out from the gap of the connecting piece 21 and pollute the environment.

[0030] The control component includes a controller and a plurality of oil mist concentration detectors 24. The controller has a 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 detector 24, the solenoid valve and the pipeline pump. When the concentration value input into the controller by the concentration detector is greater than the warning concentration value, the controller controls the solenoid valve and the pipeline pump to start and maintain the first set time. In this embodiment, the oil mist concentration detector 24 is divided into two groups, and the two groups of oil mist concentration detectors 24 are respectively arranged above the connecting member 21 and below the connecting member 21, such as Figure 3 As shown, in this embodiment, the number of each group of oil mist concentration detectors 24 is six, and the six oil mist concentration detectors 24 are evenly fixed on the inner walls on both sides of the connecting member 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 the solenoid valve to open, so that the solution is sprayed out from the nozzle to settle the oil mist in the connecting piece 21 to form waste oil. When a certain amount of waste oil is deposited, or when the waste material in the truck bed needs to be cleaned, the waste oil deposited in the truck bed can be discharged into the oil pan 14 through the oil drain valve 13.

[0032] In this embodiment, the judgment logic of the controller when receiving the concentration value input by the oil mist concentration detector 24 is as follows:

[0033] The controller obtains the first concentration data and the 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 this group of concentration detectors, 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 the solenoid valve to open and maintain the first set time, so that the solution is sprayed from the nozzle, and the oil mist in the connecting piece 21 is precipitated 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 the warning concentration value, the controller controls the pipeline pump and the solenoid valve to open and maintain the first set time, so that the solution is sprayed from the nozzle, and the oil mist in the connecting piece 21 is precipitated to form waste oil.

[0034] Example 2

[0035] Example 2 is substantially the same as Example 1, except that Figure 5 As shown, a partition is placed in the truck bed, and a plurality of filter holes are arranged on the partition. The aperture of the filter holes is larger than the aperture of the first filter screen 231 and smaller than the particle size of the waste. The partition is inclined toward the spray assembly 22, and the bottom of the truck bed is inclined away from the spray assembly 22, so that a waste oil storage cavity is formed between the bottom of the partition and the bottom of the truck bed, thereby isolating the waste from the waste oil, preventing the oil from soaking the waste, so that some waste oil remains in the waste, affecting the subsequent waste treatment. At the same time, by setting the partition inclined toward the spray assembly 22, the contact area between the solution sprayed by the spray assembly 22 and the waste is increased, so that the solution sprayed by the spray assembly 22 can be used to clean the waste, thereby reducing the difficulty of subsequent waste treatment.

[0036] At the same time, the controller also has a built-in second trigger information, which is a periodic trigger mode including a first set time and a second set time, wherein the first set time is the same as the time when the solenoid valve is opened and maintained in the first trigger information, and the control process of the second trigger information is as follows: S1 When the device is powered on and reaches the second set time, the controller controls the solenoid valve and the 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 being unable to be triggered due to the oil mist in the connector 21 not reaching the warning concentration value for a long time or the concentration detector malfunctioning, so that the low-concentration oil mist in the connector 21 overflows the shielding of the connector 21, affecting 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 the situation of continuous spray triggering and reducing the loss of solution.

[0039] The above is only an embodiment of the present invention, and common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that the technical means for solving the problems in the above-mentioned embodiments of the present invention can be used in combination to solve multiple technical problems at the same time. For those skilled in the art, several modifications and improvements can be made without departing from the technical solution of the present invention, which should also be regarded as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
