Description

Technical Field

[0001] This invention belongs to the field of molding sand processing technology, and in particular relates to an intelligent temperature-controlled improved lost foam casting production device. Background Technology

[0002] Lost foam casting, as a near-net-shape casting process, is widely used in the production of automotive parts, construction machinery, and pipe fittings due to its advantages such as high dimensional accuracy, good surface finish, and simplified processes. In the lost foam casting production process, material handling (such as foundry sand recovery, auxiliary material screening, and molten metal purification) and temperature control are key aspects affecting casting quality, production efficiency, and energy consumption. However, existing technologies still have the following prominent problems in practical applications:

[0003] Low filtration efficiency and easy clogging: In existing lost foam casting production, material filtration mostly adopts fixed filter plates or single-channel filter cartridge structures. On the one hand, fixed filter plates lack dynamic driving force, and materials easily accumulate on the surface of the filter plates, resulting in slow filtration speed, which is difficult to adapt to the needs of large-scale continuous production. On the other hand, single-channel filter cartridges cannot classify and filter materials of different particle sizes (such as coarse sand, fine sand, and foam residue fragments), which easily leads to the situation of "fine materials getting stuck in the holes and coarse materials clogging the channels". Moreover, after the filter holes are clogged, the machine needs to be stopped for disassembly and cleaning, which seriously affects the continuity of production. At the same time, frequent cleaning increases equipment wear and labor costs.

[0004] The anti-clogging mechanism has limited functionality: While some improved devices have added anti-clogging structures (such as vibrating motors and scrapers), the vibrating motor can only achieve overall vibration of the filter cartridge, resulting in poor cleaning of locally clogged areas (such as the ends of the filter cartridge and corners of the channel). The scraper, on the other hand, easily generates hard friction with the surface of the filter cartridge, which will wear down the edges of the filter holes over time, leading to a decrease in filtration accuracy. In addition, the existing anti-clogging mechanism cannot dynamically adjust the cleaning position and force according to the clogging situation in different areas of the filter cartridge, resulting in low cleaning efficiency and making it difficult to completely solve the clogging problem. Summary of the Invention

[0005] The purpose of this invention is to address the problems mentioned in the background art by providing an intelligent temperature-controlled improved lost foam casting production device that uses an anti-blocking mechanism to drive the cam to move the U-shaped plate up and down by utilizing the rotational power of the rotating rod, thus reducing the energy consumption of the equipment without the need for an additional drive motor.

[0006] To achieve the above objectives, the present invention adopts the following technical solutions:

[0007] An improved intelligent temperature-controlled lost foam casting production apparatus includes:

[0008] A collection frame is provided, with mounting plates fixedly connected to the upper ends of both side walls. A rotating rod is rotatably connected between the two mounting plates. A drive motor for driving the rotating rod is fixedly connected to one of the mounting plates. A filter cartridge is fixedly connected to the rotating rod via a support rod.

[0009] The filter cartridge is provided with multiple filter channels of different radii, and multiple filter holes distributed in a circular array are opened on the peripheral sidewalls of the multiple filter channels.

[0010] The two sides of the collection frame are respectively fixedly connected to a conveying box and a discharging box. The conveying box and the discharging box are respectively connected to both ends of the filter cylinder, and the filter cylinder is sealed and rotatably connected to the corresponding conveying box and the discharging box.

[0011] The anti-clogging mechanism is located in the collection frame below the filter cartridge. It is used to impact the filter cartridge during the operation of the lost foam casting production device to prevent the filter holes from becoming clogged.

[0012] The adjustment mechanism is used to continuously adjust the impact position of the filter cartridge during the operation of the anti-clogging mechanism to improve the anti-clogging effect.

[0013] Preferably, the anti-clogging mechanism includes cams fixedly connected to the two sides of the rotating rod, U-shaped plates slidingly connected to the two side walls of the collection frame in the vertical direction, transmission plates fixedly connected to the upper ends of the two side walls of the U-shaped plates, the cams periodically abutting and pushing the transmission plates downward during rotation, a first spring is provided between the U-shaped plate and the bottom wall of the collection frame, and multiple sets of collision components are provided at the upper end of the U-shaped plate, each set of collision components corresponding to multiple filter channels, used to impact the filter channels at the corresponding positions during the up and down movement of the U-shaped plate.

[0014] Preferably, the collision assembly includes two fixed plates fixedly connected to the upper end of the U-shaped plate, a rectangular guide rod fixedly connected between the two fixed plates, two symmetrically distributed rectangular sleeves slidably connected on the rectangular guide rod, extension rods movably connected to the side ends of the two rectangular sleeves, and an impact roller fixedly connected to the top end of the extension rod.

[0015] Preferably, the adjustment mechanism includes an L-shaped conductive plate fixedly connected to the rotating rod, a conductive ring on one of the mounting plates, and movable plates fixedly connected to the lower ends of two rectangular sliding sleeves at the same position. Electromagnets that cooperate with each other are fixedly connected to the sides of the two movable plates that are close to each other. When the two electromagnets are energized, opposite poles repel each other. A second spring is provided between the movable plate and the corresponding fixed plate. The conductive ring is divided into multiple contact areas. When the L-shaped conductive plate is in contact with different contact areas, the magnetic repulsion force between the two electromagnets is different. A lifting component is provided between the movable plate and the corresponding extension rod to synchronously adjust the height position when the horizontal position of the extension rod and the impact roller changes, so as to ensure the impact effect of the impact roller on the filter channel at the corresponding position.

[0016] Preferably, the lifting assembly includes a limiting block fixedly connected to the movable piece, an extension rod slidably connected to the movable piece, a magnetic sheet fixedly connected to the bottom end of the extension rod, and a magnetic strip fixedly connected to the upper end of the U-shaped plate to cooperate with the magnetic sheet at the corresponding position. The magnetic sheet and the magnetic strip at the corresponding position are mutually repulsive due to their similar poles.

[0017] Preferably, the magnetic strip is divided into multiple magnetic regions, and the magnetic repulsion between the magnetic sheet and the magnetic strip is different when the magnetic sheet moves above different magnetic regions.

[0018] Preferably, ventilation ducts are provided on both sides of the collection frame, and a fan is provided inside the ventilation duct.

[0019] Preferably, the upper end of the conveying box is fixedly connected to a feeding hopper, and a feeding channel is fixedly connected to one side wall of the discharging box.

[0020] Compared with existing technologies, the advantages of this intelligent temperature-controlled improved lost foam casting production device are:

[0021] 1. This invention drives the filter cartridge to rotate synchronously by a drive motor, and uses centrifugal force to accelerate the flow of materials in the filtration channel. Compared with the existing fixed filter plate filtration method, the material filtration speed is increased by 30%-50%, which can meet the material handling needs of continuous production in lost foam casting. At the same time, the rotation of the filter cartridge makes the material evenly distributed in the filtration channel, avoids local material accumulation, and further improves the filtration uniformity.

[0022] 2. This invention, by setting up an anti-clogging mechanism, uses the rotational power of the rotating rod to drive the cam to move up and down, realizing the reciprocating motion of the U-shaped plate. No additional drive motor is needed, reducing equipment energy consumption. At the same time, the gentle impact of the impact roller on the outer wall of the filter channel (made of wear-resistant metal material, the impact force can be adjusted by the elastic coefficient of the first spring) can shake off the clogging material particles and avoid wear on the filter cartridge, thus extending the service life of the filter cartridge.

[0023] 3. This invention, by setting an adjustment mechanism, dynamically changes the magnetic repulsion of the electromagnet through the cooperation of different contact areas between the L-shaped conductive sheet and the conductive ring, driving the impact roller to move horizontally. At the same time, combined with the magnetic force adjustment of the lifting component (the magnetic strip has multiple magnetic force areas to adapt to different radius filter channels), it achieves precise matching of the impact position and height, ensuring that all areas of the outer wall of the filter channel can be effectively cleaned, reducing the blockage rate to below 5%, reducing the number of downtime cleanings, and increasing the continuous operation time of the equipment by more than 60%.

[0035] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0036] Example: Refer to Figures 1 to 4 An intelligent temperature-controlled improved lost foam casting production device includes:

[0037] A collection frame 1 is provided, with mounting plates 11 fixedly connected to the upper ends of both side walls of the collection frame 1. A rotating rod 12 is rotatably connected between the two mounting plates 11. A drive motor 13 for driving the rotating rod 12 is fixedly connected to one of the mounting plates 11. A filter cartridge 14 is fixedly connected to the rotating rod 12 via a support rod.

[0038] The filter cartridge 14 is provided with multiple filter channels 2 of different radii, and multiple filter holes 21 distributed in a circular array are opened on the peripheral sidewalls of the multiple filter channels 2.

[0039] The drive motor 13 is fixed on one of the mounting plates 11. After being powered on, it can drive the rotating rod 12 to rotate at a constant speed around its own axis, and then drive the filter cartridge 14 to rotate synchronously through the support rod. The rotation of the filter cartridge 14 is the key to realizing dynamic filtration of materials. It can use centrifugal force to accelerate the flow of materials in the filter channel 2, and at the same time cooperate with the filter hole 21 to complete "material separation" (such as separating casting sand from impurities, or residual slag in molten metal).

[0040] The two sides of the collection frame 1 are respectively fixedly connected to the conveying box 3 and the discharging box 31. The conveying box 3 and the discharging box 31 are respectively connected to the two ends of the filter cylinder 14, and the filter cylinder 14 is sealed and rotatably connected to the corresponding conveying box 3 and the discharging box 31.

[0041] The material collection frame 1 is connected to a material conveying box 3 and a material discharge box 31 on both sides, forming an "input-output" channel for materials. The feed hopper 32 at the top of the material conveying box 3 allows operators or automated equipment to feed the material to be filtered into the device. The material enters the filter channel 2 of the filter cartridge 14 through the material conveying box 3. The feeding channel 33 on one side of the discharge box 31 is used to transport the filtered qualified material to the next casting process (such as molding, pouring, etc.). At the same time, the sealed rotating connection between the filter cartridge 14 and the material conveying box 3 and the discharge box 31 ensures the flexibility of the filter cartridge 14 during rotation and prevents material leakage from the connection gaps during transportation, avoiding material waste and environmental pollution.

[0042] An anti-clogging mechanism 4 is located inside the collection frame 1 below the filter cartridge 14. During the operation of the lost foam casting production device, it impacts the filter cartridge 14 to prevent clogging of the filter holes 21. The anti-clogging mechanism 4 includes cams 41 fixedly connected to the two sides of the rotating rod 12. U-shaped plates 42 are slidably connected to the two side walls of the collection frame 1 in the vertical direction. Transmission plates 43 are fixedly connected to the upper ends of the two side walls of the U-shaped plates 42. During rotation, the cams 41 periodically abut against and push the transmission plates 43 downwards. A first spring 44 is provided between the U-shaped plate 42 and the inner bottom wall of the collection frame 1. Multiple sets of collision components 45 are provided at the upper end of the U-shaped plate 42. These collision components 45 correspond to multiple filter channels 2 and are used to impact the corresponding filter channels 2 during the up-and-down movement of the U-shaped plate 42.

[0043] The collision assembly 45 includes two fixed plates 451 fixedly connected to the upper end of the U-shaped plate 42. A rectangular guide rod 452 is fixedly connected between the two fixed plates 451. Two symmetrically distributed rectangular sleeves 453 are slidably connected to the rectangular guide rod 452. An extension rod 454 is movably connected to the side end of the two rectangular sleeves 453. An impact roller 455 is fixedly connected to the top end of the extension rod 454.

[0044] The anti-clogging mechanism 4 is the core of solving the clogging problem of filter holes 21. Its operation relies on the rotational power of the rotating rod 12 to achieve synchronous linkage: the cams 41 fixed on both sides of the rotating rod 12 periodically abut and push the transmission plates 43 on the upper ends of the side walls of the U-shaped plate 42 as the rotating rod 12 rotates. When the protruding end of the cam 41 contacts the transmission plate 43, it will squeeze the transmission plate 43 downward, causing the U-shaped plate 42 to move downward along the vertical slide rail on the side wall of the collection frame 1. At this time, the first spring 44 between the U-shaped plate 42 and the inner bottom wall of the collection frame 1 is compressed and stores elastic potential energy. When the protruding end of the cam 41 disengages from the transmission plate 43, the first spring 44 releases the elastic potential energy and pushes the U-shaped plate 42 to return to its original position. This cycle continues, and the U-shaped plate 42 achieves continuous up-and-down reciprocating movement.

[0045] Multiple sets of collision components 45 are provided at the upper end of the U-shaped plate 42, corresponding one-to-one with the multiple filter channels 2 on the filter cartridge 14. They can specifically target each channel to prevent clogging. In each set of collision components 45, two fixing plates 451 are fixed to the upper end of the U-shaped plate 42 to provide support for the rectangular guide rod 452. Two rectangular sliding sleeves 453 are slidably connected on the rectangular guide rod 452 and can move horizontally along the guide rod, thereby driving the extension rod 454 connected to the side end and the impact roller 455 at the top to adjust the horizontal position. The impact roller 455 is made of wear-resistant metal material (such as stainless steel). When the U-shaped plate 42 moves up and down, the impact roller 455 will gently impact the outer wall of the corresponding filter channel 2 of the filter cartridge 14. The vibration generated by the impact can shake off the material particles stuck in the filter hole 21, preventing the filter hole 21 from being blocked due to long-term accumulation. At the same time, the "roller-shaped" design can reduce the wear of the filter cartridge 14 during the impact and extend the service life of the filter cartridge.

[0046] The adjustment mechanism 5 is used to continuously adjust the impact position of the filter cartridge 14 during the operation of the anti-clogging mechanism 4 to improve the anti-clogging effect. The adjustment mechanism 5 includes an L-shaped conductive plate 51 fixedly connected to the rotating rod 12. A conductive ring 52 is provided on one of the mounting plates 11. The lower ends of the two rectangular sliding sleeves 453 in the same position are fixedly connected to movable plates 53. Electromagnets 54 that cooperate with each other are fixedly connected to the side of the two movable plates 53 that are close to each other. When the two electromagnets 54 are energized, opposite poles repel each other. A second spring 55 is provided between the movable plate 53 and the corresponding fixed plate 451. The conductive ring 52 is divided into multiple contact areas 56. When the L-shaped conductive plate 51 is in different contact areas 56, the magnetic repulsion force between the two electromagnets 54 is different. A lifting component 57 is provided between the movable plate 53 and the corresponding extension rod 454 to synchronously adjust the height position of the extension rod 454 and the impact roller 455 when the horizontal position changes, so as to ensure the impact effect of the impact roller 455 on the filter channel 2 at the corresponding position.

[0047] The lifting assembly 57 includes a limiting block 571 fixedly connected to the movable piece 53, an extension rod 454 slidably connected to the movable piece 53, a magnetic piece 572 fixedly connected to the bottom end of the extension rod 454, and a magnetic strip 573 fixedly connected to the upper end of the U-shaped plate 42 for use with the magnetic piece 572 at the corresponding position. The magnetic piece 572 and the magnetic strip 573 at the corresponding position are like poles that repel each other.

[0048] Specifically, the magnetic strip 573 is divided into multiple magnetic regions 574. When the magnetic sheet 572 moves above different magnetic regions 574, the magnetic repulsion between the magnetic sheet 572 and the magnetic strip 573 is different.

[0049] Specifically, ventilation ducts 6 are provided on both sides of the collection frame 1, and a fan is provided inside the ventilation duct 6.

[0050] Specifically, the upper end of the feeding box 3 is fixedly connected to the feeding hopper 32, and the side wall of the discharge box 31 is fixedly connected to the feeding channel 33.

[0051] The adjustment mechanism 5 is used to optimize the impact effect of the anti-clogging mechanism 4 and avoid the local filter hole 21 from still being blocked due to the fixed impact position: When the L-shaped conductive plate 51 fixed on the rotating rod 12 rotates with the rotating rod 12, its free end will periodically contact different contact areas 56 of the conductive ring 52 on the mounting plate 11. The multiple contact areas 56 of the conductive ring 52 correspond to different current output intensities. When the L-shaped conductive plate 51 contacts a certain contact area 56, the current will be transmitted to the two electromagnets 54 through the wire, so that the electromagnets 54 are energized and generate a magnetic force of opposite poles repulsion. Because the current intensity varies in different contact areas 56, the magnitude of the magnetic repulsion between the two electromagnets 54 also changes accordingly: when the magnetic repulsion increases, it will push the two moving pieces 53 to slide away from each other along the rectangular guide rod 452 (at this time, the second spring 55 between the moving piece 53 and the fixed plate 451 is stretched); when the magnetic repulsion decreases, the tension of the second spring 55 will cause the moving piece 53 to reset. The horizontal movement of the moving piece 53 will simultaneously drive the rectangular sliding sleeve 453, the extension rod 454 and the impact roller 455 to adjust the horizontal impact position, realize the "dynamic change of impact point", and ensure that all areas of the outer wall of the filter channel 2 can be impacted, completely eliminating the dead corner of blockage.

[0052] The function of the lifting assembly 57 is to synchronously adjust the height of the impact roller 455 when the horizontal position changes, so as to ensure that the impact roller 455 is always in close contact with the outer wall of the corresponding filter channel 2. The limiting block 571 on the moving plate 53 is used to limit the horizontal displacement of the extension rod 454 to prevent the extension rod 454 from shifting when it moves with the impact roller 455. The extension rod 454 is slidably connected to the moving plate 53 and can slide up and down in the vertical direction. The magnetic sheet 572 fixed at its bottom end and the magnetic strip 573 fixed at the upper end of the U-shaped plate 42 are opposite to each other with the same pole (e.g., both are N poles). The magnetic force of "like poles repel each other" is used to push the extension rod 454 upward. Meanwhile, multiple magnetic regions 574 on the magnetic strip 573 correspond to different magnetic intensities: when the magnetic sheet 572 moves above a certain magnetic region 574 with the moving sheet 53, if the magnetic force in that region is strong, it will push the extension rod 454 to move upward more, causing the impact roller 455 to rise in height; if the magnetic force in that region is weak, the extension rod 454 will decrease in height under the balance of its own weight and magnetic force. This design can adapt to the outer wall curvature of the filter channel 2 with different radii, ensuring that no matter where the impact roller 455 moves horizontally, it can maintain stable impact contact with the outer wall of the filter channel 2, avoiding impact "missing" or "over-squeezing" due to differences in channel radius.

[0053] This device employs a "one-rotor, multiple-drive" power distribution mode: the drive motor 13 (a high-efficiency permanent magnet synchronous motor with a rated power of 0.75kW and an energy efficiency rating of IE4) not only drives the filter cartridge 14 to rotate but also provides power to the anti-clogging mechanism 4 and the adjusting mechanism 5 simultaneously through mechanical linkage structures such as the cam 41 and the L-shaped conductive plate 51, avoiding the energy consumption accumulation caused by the independent operation of multiple motors in traditional devices. Actual measurements show that this design can reduce the total power of the equipment by 30%-40% and the energy consumption per unit material processing area to 0.3-0.4kW. h / kg.

[0054] Meanwhile, a temperature sensor (accuracy ±0.5℃) and a flow valve (adjustment range 0-500m³ / h) are installed inside the ventilation duct 6 to collect parameters such as air temperature inside the frame 1, temperature difference between material inlet and outlet, and ambient humidity in real time. The control system dynamically adjusts based on a PID algorithm.

[0055] When the temperature of the foundry sand is higher than the target value (e.g., 30°C), the cold air flow rate is automatically increased (up to 500 m³ / h) and the inlet air temperature is reduced (down to 10°C).

[0056] When the heat preservation requirement of molten metal is high, switch to hot air circulation and stabilize the air intake temperature within a preset range (such as 150-200℃) through an electric heating module (power adjustable, 0-2kW).

[0057] Combined with the filter cartridge speed 14 (the higher the speed, the larger the heat dissipation area of ​​the material), the air volume is dynamically matched to avoid energy waste caused by "overcooling" or "overheating", and the temperature control accuracy is controlled within ±1℃.

[0058] The functional principle of this invention can be explained through the following operational methods:

[0059] Equipment startup and material input: First, connect the power supply to the drive motor 13 and the fan in the ventilation duct 6. The drive motor 13 drives the rotating rod 12 and the filter cartridge 14 to rotate at a constant speed. The fan starts to realize the air circulation and temperature control in the collection frame 1. Then, the lost foam casting material to be filtered (such as mixed casting sand, auxiliary materials containing impurities, etc.) is put into the conveying box 3 through the feed hopper 32. Under the action of gravity and centrifugal force of the rotation of the filter cartridge 14, the material enters the corresponding filtration channel 2 of the filter cartridge 14 (the channel with matching radius is selected according to the particle size of the material).

[0060] Dynamic filtration process: When the filter cylinder 14 rotates, the material flows along the channel axis in the filtration channel 2. At the same time, some material (or impurities) that meet the particle size requirements of the filter hole 21 permeates through the filter hole 21 into the collection frame 1 (the impurities are collected and processed by the collection frame 1, while the qualified material remains in the channel). The filtered qualified material rotates with the filter cylinder 14 to the discharge box 31 position, and is finally transported to the next casting process through the feeding channel 33.

[0061] Anti-clogging and impact adjustment: When the rotating rod 12 rotates, it synchronously drives the cam 41 to rotate. The cam 41 periodically pushes the U-shaped plate 42 to move up and down back and forth, so that the impact roller 455 of the impact component 45 continuously impacts the outer wall of the filter channel 2, shaking off the material that is blocking the filter hole 21. At the same time, the L-shaped conductive sheet 51 contacts the conductive ring 52 at different contact areas 56, changing the magnetic repulsion force of the electromagnet 54, pushing the impact roller 455 to move horizontally. With the magnetic adjustment of the lifting component 57, the impact position and height are dynamically adapted to ensure that there are no dead angles in anti-clogging.

[0062] Temperature control and environmental optimization: The fan in the ventilation duct 6 continuously supplies temperature-controlled air, which exchanges heat with the filter cartridge 14 and the material to stabilize the material temperature within the range required by the casting process (e.g., casting sand needs to be cooled to 20-30℃); at the same time, the air flow carries away dust and discharges it through another set of ventilation ducts 6 (which can be connected to external dust collection equipment for further treatment), ensuring the safety and environmental protection of the device operation.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
