Description

Technical Field

[0001] The invention relates to the field of casting cutting, and in particular to a dust removal air curtain structure, a dust removal device and a cutting system for casting cutting. Background Art

[0002] In the foundry industry, small and medium-sized castings are extremely difficult to cut due to their complex geometric structures and diverse material combinations. Traditional cutting methods usually rely on experienced workers to perform manual operations. When performing cutting, workers not only have to deal with the redundant parts of the castings, such as runners and risers, but also have to deal with complex cutting paths and angles, which requires extremely high technical skills. The manual cutting process is inefficient and the quality is unstable, making it difficult to ensure production consistency. In this context, the introduction of automated casting cutting systems is particularly important. Automated cutting equipment can achieve high-precision cutting operations under complex casting shapes and paths, reduce dependence on manual operations, and improve production efficiency and cutting quality. At the same time, automated cutting rooms can standardize operating procedures to ensure that every casting can be cut in the same way and speed, thereby ensuring product consistency. However, in the application of automated cutting rooms, dust problems still exist, and due to the high sensitivity of automated equipment, the impact of dust on equipment is more significant.

[0003] The dust problem has always been a hidden danger that cannot be ignored in the casting cutting process. Due to the high-speed rotation of the cutting tool and the intense friction with the casting surface, a large amount of metal particles and sand dust are generated in the air and are difficult to completely control. These dusts are suspended in the workshop, causing the air quality to deteriorate. The fine particulate matter (PM10 and PM2.5) generated can enter the lungs through breathing, causing acute and chronic respiratory diseases such as cough, bronchitis, pneumoconiosis, etc. In addition to skin and eye irritation, it may also cause metal poisoning, affecting the nervous system, kidneys and other organs. Even worse, it will affect the mental health of workers, which will lead to an increase in employment costs and a decrease in work efficiency to a certain extent. In addition, dust is deposited on the surface of the equipment, which may accelerate the wear and corrosion of the equipment, shorten the service life of the equipment, and increase maintenance costs. Deposited in the workshop, it also requires frequent cleaning, which increases labor intensity and operating costs.

[0004] Traditional dust removal methods, such as ventilation systems and exhaust equipment, can alleviate the dust problem to a certain extent. However, due to the dispersion and irregularity of dust generated during casting cutting, these methods often find it difficult to capture and process all the dust, resulting in a relatively high dust concentration in the workshop. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a dust removal air curtain structure for casting cutting, which can quickly and thoroughly capture the smoke generated by cutting.

[0006] In order to solve the above technical problems, the technical solution of the present invention is: a dust removal air curtain structure for casting cutting, comprising a dust suction port, a horizontal air curtain and at least three vertical air curtains; wherein,

[0007] All vertical air curtains are arranged at intervals along a preset closed-loop trajectory, and the air outlet of each vertical air curtain faces the next vertical air curtain in the preset rotation direction. All vertical air curtains work together to form an airflow barrier around the smoke source;

[0008] The vertical air curtain closest to the smoke source is taken as a calibration vertical air curtain, and starting from the calibration vertical air curtain, other vertical air curtains except the calibration vertical air curtain gradually increase in height along a preset rotation direction;

[0009] The dust suction port is used to suck smoke and dust inside the airflow barrier at the top of the airflow barrier;

[0010] The horizontal air curtain is located outside the annular track, and is used for blowing air toward the dust suction port at a position higher than the airflow barrier or directly facing the upper end of the airflow barrier.

[0011] In order to further improve the versatility of the entire dust removal air curtain structure, the height of each vertical air curtain is adjustable.

[0012] In order to further improve the dust removal effect of the horizontal air curtain, the air supply direction of the horizontal air curtain is inclined downward compared to the horizontal direction.

[0013] Furthermore, the angle at which the air supply direction of the horizontal air curtain is tilted downward compared to the horizontal direction is β, and the calculation formula of β is:

[0014] tanβ=y / (X+B);

[0015] Among them, y is the effective dust collection height of the dust suction port; X is the effective dust collection width of the dust suction port; B is the horizontal distance between the front edge of the dust suction port and the outlet of the horizontal air curtain.

[0016] Furthermore, the outlet wind speed v of the vertical air curtain is L The formula for determining is:

[0017]

[0018] Where ΔP is the pressure difference between the air inside and outside the airflow barrier; ρ is the air density.

[0019] Furthermore, the wind speed v generated by the negative pressure at the suction port is C The formula for determining is:

[0020] v C >v y ;

[0021] Among them, v y is the rising velocity of smoke, and the calculation formula is: y =0.003(t y -t n ), t y is the temperature of the smoke airflow, t n is the temperature of the surrounding air.

[0022] Furthermore, the outlet wind speed v of the horizontal air curtain is H The calculation formula is:

[0023]

[0024] Among them, v C is the wind speed formed by the negative pressure of the suction port; a is the turbulence coefficient; B is the horizontal distance between the front edge of the suction port and the outlet of the horizontal wind curtain; b is the distance between the horizontal wind curtain and the top of the cutting room.

[0025] The invention also relates to a dust removal device for casting cutting, comprising a dust removal air curtain structure for casting cutting.

[0026] Furthermore, the dust removal device for casting cutting also includes a filter, the air inlet of the filter is connected to the dust suction port, and the air outlet is respectively connected to the horizontal air curtain and each vertical air curtain.

[0027] The invention also relates to a cutting system for casting cutting, comprising a dust removal device for casting cutting.

[0028] After adopting the above technical solution, the present invention has the following beneficial effects:

[0029] 1. Capture smoke and dust thoroughly and quickly: the air outlet of the previous vertical wind curtain faces the next vertical wind curtain, so that the airflow is distributed more evenly in a straight line direction, and a relatively complete barrier can be formed locally to prevent the diffusion of air or smoke and dust. It can also prevent the heat generated during the cutting process from leaking out and can quickly take away the heat. The vertical wind curtain closest to the smoke and dust source is the lowest, and gradually increases to the vertical wind curtain far away from the smoke and dust source. This incremental height design helps to form a natural airflow gradient, guide the airflow to move upward, and avoid the airflow being too dispersed or turbulent on the ground. At the same time, the height difference is used to drive the airflow to flow and converge upward, forming a natural "guiding effect". After the smoke generated by the smoke and dust source converges upward under the action of the airflow barrier, it reaches the suction port more thoroughly and quickly under the blowing of the horizontal wind curtain. The present invention can quickly and thoroughly remove the smoke generated by the smoke and dust source, and the dust removal efficiency is high.

[0030] 2. Efficient smoke control: The dust removal air curtain structure can quickly gather and guide the smoke and concentrate it at the dust suction port, greatly reducing the diffusion of smoke in the air during the cutting process, ensuring the cleanliness of the working environment, and realizing efficient control of smoke in the cutting room through the seamless integration of the dust removal air curtain structure and filters.

[0031] 3. Closed-loop circulation system: Through the innovatively designed closed-loop circulation system, the filtered air is reintroduced into the dust removal air curtain structure, forming an air recycling system, which not only reduces energy consumption, but also improves resource utilization, which is in line with the environmental protection concept of green manufacturing.

[0032] 4. Improve production efficiency: In the automated cutting room system, the dust removal air curtain structure and filters work together to ensure that the working accuracy of the equipment is not affected by smoke and dust during the cutting process, thereby ensuring the efficiency and stability of the cutting operation. This advantage enables the production line to operate stably for a long time, greatly improving the overall production efficiency.

[0033] 5. Environmental friendliness: The dust removal air curtain structure of the present invention can effectively prevent smoke and dust from polluting the external environment. The dust removal device combined with multi-layer filtration technology ensures that the discharged air meets strict environmental protection standards, significantly reduces the negative impact of industrial production on the environment, and is highly environmentally friendly.

[0034] 6. High adaptability and flexibility: The dust removal air curtain structure and dust removal device designed by the present invention are highly adaptable and can be flexibly adjusted according to different cutting tasks and workpiece types. Whether it is a casting with a complex shape or a large-sized workpiece, it can be efficiently processed through the system, expanding the application range of the cutting room device.

[0035] 7. Improve work safety: Multiple safety mechanisms introduced in the system design, such as the airflow barrier of the dust removal air curtain structure, can not only effectively control smoke and dust, but also prevent the spillage of sparks and heat, reducing the safety risks in the cutting process and ensuring the safety of operators.

[0036] 8. Improve economic benefits: By reducing smoke pollution, improving cutting efficiency, and reducing energy consumption, the present invention can significantly reduce production costs, while extending the service life of the equipment, and has higher economic benefits and market competitiveness.

[0043] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0044] Embodiment 1

[0045] like Figures 1 to 5 As shown, a dust removal air curtain structure for casting cutting includes a dust suction port 1, a horizontal air curtain 2 and at least three vertical air curtains 3; wherein,

[0046] All vertical air curtains 3 are arranged at intervals along a preset closed-loop trajectory, and the air outlet of each vertical air curtain 3 faces the next vertical air curtain 3 in the preset rotation direction. All vertical air curtains 3 work together to form an airflow barrier around the periphery of the smoke source;

[0047] The vertical air curtain 3 closest to the smoke source is taken as the calibration vertical air curtain 3, and starting from the calibration vertical air curtain 3, the other vertical air curtains 3 except the calibration vertical air curtain 3 gradually increase in height along the preset rotation direction;

[0048] The dust suction port 1 is used to suck the smoke and dust in the airflow barrier at the top of the airflow barrier;

[0049] The horizontal air curtain 2 is located outside the circular track, and is used for blowing air toward the dust suction port 1 at a position higher than the airflow barrier or directly facing the upper end of the airflow barrier.

[0050] It should be noted that, in the present embodiment, the heights of the vertical air curtains 3 are different, more specifically, the highest points of the air outlets of the vertical air curtains 3 are different.

[0051] Specifically, the air outlet of the previous vertical wind curtain 3 is directly opposite to the next vertical wind curtain 3, so that the airflow is distributed more evenly in a straight line direction, and a relatively complete barrier can be formed locally to prevent the diffusion of air or smoke, and to prevent the heat generated during the cutting process from escaping, and to quickly take away the heat. The vertical wind curtain 3 closest to the smoke source is the lowest, and gradually increases to the vertical wind curtain 3 far away from the smoke source. This incremental height design helps to form a natural airflow gradient, guide the airflow to move upward, and avoid the airflow being too dispersed or turbulent on the ground. At the same time, the height difference is used to drive the airflow to flow and converge upward, forming a natural "guiding effect". After the smoke generated by the smoke source converges upward under the action of the airflow barrier, it reaches the dust suction port more thoroughly and faster under the blowing of the horizontal wind curtain 2, minimizing the impact on the working area of ​​the cutting robot 7. Therefore, this embodiment can quickly and thoroughly remove the smoke generated by the smoke source, with high dust removal efficiency, and is suitable for scenes where the airflow direction needs to be precisely controlled, especially suitable for concentrated adsorption of smoke generated during the cutting process in some closed scenes.

[0052] In one example, the lowest vertical wind curtain 3 is set downwind of the smoke source (the starting point of the airflow direction) with a height of 1.5 meters, and the highest vertical wind curtain 3 is set upwind away from the smoke source with a height of more than 2.5 meters.

[0053] In addition, each vertical wind curtain 3 blows directly toward the next vertical wind curtain 3, which can ensure the concentration of the jet. The more concentrated the wind curtain jet is, the stronger the anti-diffusion ability is, the smaller the wind curtain's suction effect on the still air on both sides of the jet airflow is, and the wider the effective range of the unit wind curtain flow is.

[0054] It should be noted that "the more concentrated the jet is", the stronger the directionality of the jet is, that is, the smaller the scattering angle of the airflow is, the jet remains in a narrow range, and moves in a certain direction at high speed. Concentrated airflow usually means that the jet is more directional and less diffuse. In other words, the airflow does not diffuse outward, but is ejected with tight directionality. When the jet is very concentrated, the diffusion angle of the airflow decreases, most of the energy of the airflow is concentrated in its forward direction, and the streamline is more linear. In this case, the energy of the airflow is mainly used to maintain directionality, rather than to suck the surrounding still air outward. For a general annular airflow barrier, the flow of airflow in the annular space usually forms an updraft similar to a tornado on both sides, which does drive the air inside and outside the ring to move upward together. In this embodiment, the airflow of the annular airflow barrier is very concentrated. When the airflow is concentrated, the entrainment effect of the internal air will be more significant than that of the external air, that is, the rising direction of the airflow is clearer, and the entrainment effect formed will be concentrated inside the ring, rather than the still air on both sides. This means that the air inside will be more easily entrained in the rising airflow, while the air outside will have a weaker entrainment effect due to the limited contact area.

[0055] In this embodiment, the air outlet of the vertical air curtain 3 is in the shape of a slit, and the width is preferably 5-10 mm, which can further ensure the concentration of the jet.

[0056] In addition, wind speed is also important for the concentration of the jet. In order to further ensure the jet concentration of the vertical wind curtain 3, preferably, the outlet wind speed v of the vertical wind curtain 3 is L The formula for determining is:

[0057]

[0058] Where ΔP is the pressure difference between the air inside and outside the airflow barrier; ρ is the air density.

[0059] In this embodiment, if Figure 1 and Figure 2 As shown, four vertical air curtains 3 are provided, and the four vertical air curtains are arranged in a rectangular shape, and the direction of the airflow barrier rotates 90 degrees each time.

[0060] The air volume Q1 of a single vertical air curtain 3 needs to be calculated based on the area of ​​the air curtain and the wind speed. The area of ​​the air curtain is the product of the height H and width W of the outlet: Q1 = A × v = H × W × v L .

[0061] The preset rotation direction can be clockwise or counterclockwise. Figure 1 and Figure 2 In the illustrated embodiment, the preset direction of rotation is counterclockwise.

[0062] In this embodiment, preferably, the air supply direction of the horizontal air curtain 2 is inclined downward compared to the horizontal direction.

[0063] Specifically, when the smoke rises to the upper end of the airflow barrier, it has a rising speed. Setting the air supply direction of the horizontal air curtain 2 to be tilted downward can block the rising smoke, thereby better ensuring that the smoke is turned to move toward the dust suction port 1.

[0064] More preferably, the angle at which the air supply direction of the horizontal air curtain 2 is tilted downward compared to the horizontal direction is β, and the calculation formula of β is: tanβ=y / (X+B);

[0065] Wherein, y is the effective dust collecting height of the dust suction port 1, that is, the height from the lower edge to the upper edge of the entire dust suction port 1; X is the effective dust collecting width of the dust suction port 1, that is, the horizontal distance of the entire dust suction port 1 from the edge (rear edge) away from the horizontal wind curtain 2 to the edge (front edge) close to the horizontal wind curtain 2; B is the horizontal distance between the front edge of the dust suction port 1 and the air outlet of the horizontal wind curtain 2.

[0066] In this embodiment, preferably, the wind speed v formed by the negative pressure of the dust suction port 1 is C The formula for determining is:

[0067] v C >v y ;

[0068] Among them, v y is the rising velocity of smoke, and the calculation formula is: y =0.003(t y -t n ), t y is the temperature of the smoke airflow, t n is the temperature of the surrounding air.

[0069] In this way, smoke and dust can be better absorbed.

[0070] In this embodiment, preferably, the outlet wind speed v of the horizontal air curtain 2 is H The calculation formula is:

[0071]

[0072] Among them, v C is the wind speed formed by the negative pressure of the dust suction port 1; a is the turbulence coefficient; B is the distance between the front edge of the dust suction port 1 and the air outlet of the horizontal air curtain 2, and b is the distance between the horizontal air curtain 2 and the top of the cutting room 5.

[0073] In this way, smoke and dust can be better absorbed.

[0074] Calculation of the air volume Q2 of the horizontal air curtain: The air volume Q2 of the horizontal air curtain can be determined according to the following formula:

[0075] Q2=3600bv H .

[0076] Embodiment 2

[0077] On the basis of the first embodiment, the height of each vertical air curtain 3 is adjustable.

[0078] Specifically, although the smoke source is not located at the center of the airflow barrier, considering that the cutting position, that is, the position of the smoke source, will change accordingly depending on the size of the casting, the calibrated vertical wind curtain can also be replaced with another vertical wind curtain 3. The cutting room 5 is mass-produced, and the height of each vertical wind curtain 3 is adjustable. The height of each vertical wind curtain 3 can be adjusted according to the requirements of the production line to achieve the purpose of making the vertical wind curtain 4 closest to the smoke source the shortest, so that the dust removal wind curtain structure in this embodiment can be applied to various scenarios and has strong versatility.

[0079] In addition, there are many height-adjustable structures, for example, a base is provided, the lower end of the vertical air curtain 3 is slidably installed in the base, and the vertical air curtain 3 can be pushed to slide upward or downward by a cylinder, an electric cylinder, an electric push rod, etc., and the height of the vertical air curtain 3 can also be adjusted manually. Generally speaking, for the same type of cutting casting, after the height of each vertical air curtain 3 is adjusted, no further adjustment is made later.

[0080] Embodiment 3

[0081] like Figure 3 As shown, a dust removal device for casting cutting includes the dust removal air curtain structure for casting cutting in embodiment one or embodiment two.

[0082] In this embodiment, if Figure 3 As shown, the dust removal device for casting cutting further includes a filter 4, the air inlet of the filter 4 is connected to the dust suction port 1, and the air outlet is connected to the horizontal air curtain 2 and each vertical air curtain 3 respectively.

[0083] like Figure 3 As shown, the inlet of the filter 4 is connected to the dust suction port 1 through the smoke and dust duct, and the outlet is connected to the horizontal air curtain 2 and each vertical air curtain 3 through the air duct 9.

[0084] The bottom of the vertical air curtain 3 is an air inlet, and the air duct 9 is connected to the air inlet at the bottom of the vertical air curtain 3. The filter 4 can be a bag filter, which adopts multi-layer filtering technology to achieve efficient treatment of smoke and dust in the airflow barrier. The filtered air is reintroduced into the air curtain system to form a closed cycle, improve resource utilization, and significantly reduce pollution to the external environment.

[0085] The design of this device not only achieves efficient dust removal and pollutant treatment, but also reduces energy consumption through a closed circulation system, improving the cleanliness and safety of the cutting environment. The system is suitable for cutting rooms of all sizes5 and has significant environmental and economic benefits in a variety of cutting applications.

[0086] In practical applications, the dust removal rate of a dust removal device using a dust removal air curtain structure can reach 70%. After repeated dust removal through a circulation system, the amount of residual smoke converges in geometric series (as shown in the formula: R n =(1-E) n , where R n It represents the amount of remaining smoke after the nth cycle, E represents the single dust removal efficiency, and n represents the number of cycles. After several rounds of cycles, the dust removal rate of cutting room 5 can reach more than 99%, which is enough to meet production requirements.

[0087] Embodiment 4

[0088] like Figure 4 and Figure 5As shown, a cutting system for casting cutting includes the dust removal device for casting cutting in embodiment three.

[0089] like Figure 4 and Figure 5 As shown, the cutting system for casting cutting also includes a cutting room 5, a clamping tool 6, a cutting robot 7 and a waste storage box 10, a dust suction port 1 is arranged on the top of the cutting room 5, a horizontal air curtain 2 and a vertical air curtain 3 are respectively installed in the cutting room 5, the clamping tool 6 is located in the airflow barrier and is used to clamp the casting, and the cutting robot 7 is used to cut the casting, wherein there is no requirement for the position of the cutting robot 7, as long as the operating head of the cutting robot 7 is located in the airflow barrier. The waste storage box 10 is used to carry the casting and receive the cutting waste.

[0090] The working process of the entire cutting system is as follows: the waste storage box 10 is driven by a chain, and can automatically transport the casting to be cut from the front end of the production line to the designated position in the cutting room 5 to ensure the accurate positioning of the casting. Then the clamping tool 6 fixes and hangs the casting, and the cutting robot 7 performs the cutting. During the whole process, the dust removal device is turned on, and the airflow barrier formed by the vertical air curtain 3 concentrates the smoke into a wind column. The horizontal air curtain 2 sends the smoke to the suction port 1 at a certain angle, and then to the filter 4. After being processed, it is sent to the vertical air curtain 3 and the horizontal air curtain 2 to achieve a closed loop.

[0091] The dust removal air curtain structure and even the dust removal device are the key points of the cutting system. By setting up several vertical air curtains 3 around the cutting area, a strong airflow barrier is formed to effectively gather the smoke and dust scattered during the cutting process, achieve the purpose of guiding and blocking the dust, and quickly capture and introduce it into the dust suction port 1. The smoke and dust will be efficiently filtered by the filter 4, and the filtered clean air will be sent back to the dust removal air curtain structure to form a closed-loop circulation system. This not only ensures that the smoke and dust are quickly captured and processed at the source, but also reduces environmental pollution and energy waste, significantly improves the air quality of the workshop, improves the health of workers, and extends the service life of equipment. Combined with the precise control and stable operation of the automated cutting room, it can not only ensure an efficient and dust-free cutting process, but also provide a safer and cleaner working environment while greatly improving production efficiency, reducing threats to workers' health and extending the service life of equipment.

[0092] In this embodiment, the structure of the clamping tool 6 can be, but is not limited to, a frame, a chuck, a suspension rod and a rotary drive member, the suspension rod is connected to the chuck, the rotary drive member is installed on the frame, the output end is connected to the suspension rod, the chuck is used to fix and limit the casting from all sides, and the suspension rod can realize the smooth lifting and lowering of the casting in the vertical direction through the built-in hydraulic linear drive device. This function enables the casting to be adjusted to a suitable height according to the cutting needs to ensure the accuracy of the cutting position. The accuracy of vertical movement is very important for the cutting operation, especially when multiple cuts or cutting of different parts are required. This function can avoid cutting errors caused by inconsistent heights. The rotary drive device uses a servo motor, allowing the workpiece to be accurately adjusted in angle on the vertical axis, so that the cutting tool can operate the workpiece from multiple angles, which not only improves the flexibility of cutting, but also ensures the full range of processing of complex-shaped workpieces.

[0093] When the casting is lifted by the clamping fixture of the above structure, it is cut by rotating and vertically moving in cooperation with the cutting robot 7. The precise control function of the lifting rod not only reduces the need for manual intervention, thereby reducing human operation errors, but also improves the degree of automation of the overall cutting process, ensuring efficient production.

[0094] In this embodiment, the cutting robot 7 is the core of the automated operation in the cutting room 5. It is equipped with high-precision sensors, control systems and advanced machine vision technology, and can accurately cut castings according to preset programs. The cutting robot 7 integrates cameras and other visual sensors, and can recognize the complex shapes and sizes of castings through real-time image capture and processing, and automatically adjust the cutting path and parameters. This machine vision system not only improves the adaptability of the cutting robot 7 when facing irregular or unknown workpieces, but also can perform self-correction and optimization through image data feedback, ensuring high precision and consistency of the cutting process.

[0095] In addition, the cutting robot 7 can be seamlessly connected with the chain conveyor system, and the transmission status and position of the castings can be monitored in real time through the visual system, thereby further improving the automation and flexibility of the cutting operation. The robot also has learning and adaptive functions, and can gradually optimize its cutting strategy when handling diverse production tasks, improve production efficiency and reduce operational errors.

[0096] Through the above-mentioned structural setting, the combination of machine vision and intelligent control, the cutting robot 7 has reached new heights in precision, efficiency and reliability, ensuring the cutting quality of castings of various shapes and sizes, while enhancing the overall intelligence level and application value of the cutting system.

[0097] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description.
