Description

Technical Field

[0001] This application relates to the field of metal casting processing technology, and in particular to a device for treating welding slag in metal casting processing. Background Technology

[0002] In the metal casting process, welding is an economical and efficient tool for defect repair, as well as a core technology for achieving modular manufacturing and performance improvement. After welding, the slag (also known as flux coating) must be removed as a byproduct in order to check the true quality of the weld and carry out subsequent painting or anti-corrosion treatment.

[0003] The main methods for removing weld slag after welding include mechanical removal, chemical removal, and some specific processes or auxiliary methods. Among them, mechanical removal is generally carried out on the weld by using a slag hammer, a grinding wheel, or sandblasting.

[0004] However, after the welding slag is processed, it is randomly splashed onto the equipment and the ground at the work station. Workers need to clean up the welding slag in a concentrated manner, and some impurities are easily mixed in during the cleaning process. This not only increases the labor intensity of the workers, but also affects the quality of subsequent recycling. Summary of the Invention

[0006] Therefore, one objective of this application is to provide a metal casting welding slag treatment device that collects welding slag under negative pressure by using a filtration mechanism, which not only reduces the labor intensity of workers but also ensures the quality of subsequent welding slag recycling.

[0007] To achieve the above objectives, a first aspect of this application provides a slag treatment device for metal casting processing, comprising: a housing, a slag inlet mechanism, a filtration mechanism, and a discharge mechanism.

[0008] In addition, the metal casting welding slag treatment device proposed in the above embodiments of this application may also have the following additional technical features: Furthermore, the elastic filter assembly includes a plate component, a filter screen component, and multiple arc-shaped fasteners. The plate component is connected to the housing, and the plate component has a circular hole with a groove on the inner wall of the circular hole. The filter screen component is located inside the circular hole, and its outer edge extends into the groove. The multiple arc-shaped fasteners pass through the filter screen component and are slidably connected to the filter screen component. The two ends of the arc-shaped fasteners are respectively connected to the inner wall of the circular hole.

[0009] Furthermore, the filter component includes a filter screen, a central plate, and multiple spring plates. The filter screen has an arc-shaped cross-section. The central plate is located on top of the filter screen, and the multiple spring plates are arranged in an array on the filter screen. The outer edge of the filter screen extends into the groove, and the outer wall of the filter screen abuts against the side wall of the groove. The arc-shaped fixing member penetrates the filter screen. The rod penetrates the central plate.

[0010] Furthermore, the plate component includes an outer frame, an inner frame, and a slewing bearing, wherein the slewing bearing is disposed between the outer frame and the inner frame, the outer frame is connected to the housing, and the groove is formed on the inner frame.

[0011] Furthermore, the filtration mechanism also includes a rotating assembly, which comprises a gear ring drive component, a worm gear drive component, and a drive motor. The gear ring drive component is connected to the inner frame, and the worm gear drive component is connected to the gear ring drive component. Both ends of the worm gear drive component are rotatably connected to the inner wall of the housing, and one end of the worm gear drive component penetrates through the inner wall of the housing. The drive motor is mounted on the housing, and its output shaft is connected to one end of the worm gear drive component.

[0012] Furthermore, the discharge mechanism includes an auger conveyor and two collection troughs. The inner bottom wall of the housing has two through slots, each located on one side of a corresponding elastic filter assembly.

In addition, by driving the elastic filter component to deform, the release of elastic potential energy brings a large impact force that throws out the welding slag stuck on the surface of the elastic filter component, thus preventing the elastic filter component from becoming clogged.

[0019] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0020] The following describes a metal casting welding slag treatment apparatus according to an embodiment of this application, with reference to the accompanying drawings.

[0021] like Figures 1-5 As shown, the metal casting processing slag treatment device of this application embodiment may include: a housing 1, a slag feeding mechanism 2, a filtering mechanism 3, and a discharge mechanism 4.

[0022] The shell 1 has an opening, and the slag inlet mechanism 2 is connected to the shell 1 through the opening. The slag inlet mechanism 2 is used to remove the welding slag and introduce it into the interior of the shell 1.

[0023] The filtration mechanism 3 includes two flexible filter components 31, a drive component 32, and a negative pressure suction component 33.

[0024] Two elastic filter components 31 are respectively disposed inside the housing 1. The cross-section of the elastic filter component 31 is arranged in an arc shape. The elastic filter component 31 is used to block welding slag.

[0025] It should be noted that the two elastic filter components 31 described in this embodiment have different filter hole sizes. The elastic filter component 31 with a smaller hole diameter is arranged behind the elastic filter component 31 with a larger hole diameter, thereby reducing the filtration pressure of a single elastic filter component 31.

[0026] Understandably, the cross-section of the elastic filter component 31 is arranged in an arc shape, which not only allows it to have sufficient deformation capacity during deformation to obtain greater impact force, but also increases the filtration area compared to a planar structure.

[0027] The drive assembly 32 includes a rod 321, an electric telescopic rod 322, and three baffles 323. The drive assembly 32 is used to apply force to the elastic filter assembly 31 to force it to deform.

[0028] The rod 321 passes through two elastic filter components 31 and is slidably connected to the elastic filter components 31. The electric telescopic rod 322 is installed on one side of the outer wall of the housing 1 and the output end of the electric telescopic rod 322 is connected to one end of the rod 321.

[0029] Three baffles 323 are sequentially fitted onto the outside of the rod 321. One baffle 323 is located between two elastic filter components 31, and the other two baffles 323 are located on the outside of the two elastic filter components 31 respectively. The distance between the two baffles 323 is equal to the distance between the two elastic filter components 31.

[0030] It is understandable that the distance between the two baffles 323 is equal to the distance between the two elastic filter components 31, which can ensure that the two baffles 323 push the two elastic filter components 31 to deform simultaneously, and the other baffle 323 will not restrict the elastic filter component 31, so that the elastic potential energy of the elastic filter component 31 is fully released.

[0031] In addition, to further optimize the filtration effect of welding slag, multiple elastic filter components 31 can be set. The filter pore diameters of the multiple elastic filter components 31 are different. The specific number of baffles 323 and other structures can be adapted. The specific structure and working principle are the same as the technical solution provided in this application, and will not be described in detail here.

[0032] In the above embodiment, the electric telescopic rod 322 is connected to an external relay (not shown in the figure). The external relay can adjust the operating interval of the electric telescopic rod 322, so that the elastic filter assembly 31 operates cyclically.

[0033] The negative pressure extraction component 33 is installed on the outer wall of the other side of the housing 1. The negative pressure extraction component 33 is used to create a negative pressure environment inside the housing 1 so that external air carrying welding slag enters the interior of the housing 1 through the slag inlet mechanism 2.

[0034] It should be noted that the specific structure and working principle of the negative pressure suction component 33 described in this embodiment have been disclosed in the prior art, so they will not be described in detail here.

[0035] The discharge mechanism 4 is located at the bottom of the housing 1. The discharge mechanism 4 is used to output the welding slag temporarily stored at the bottom of the housing 1 to an external collection device for unified transfer and processing.

[0036] In the embodiments of this application, a controller (not shown in the figure) is provided on the housing 1. The slag feeding mechanism 2, the filtering mechanism 3 and the discharge mechanism 4 are respectively connected to the controller. The controller can communicate with an external host computer via wired or wireless means to receive instructions sent by the host computer. The controller may include a control panel, which is provided with a display screen and function buttons, so that relevant personnel can conveniently view the data of the metal casting processing welding slag treatment device during operation through the display screen, and conveniently adjust and modify the data by inputting the buttons.

[0037] Specifically, relevant technicians use welding processes to repair defects in castings, and then use this device to treat the welding slag.

[0038] When the device is started, the slag feeding mechanism 2, the filtration mechanism 3 and the discharge mechanism 4 begin to operate. The relevant technicians apply the end of the slag feeding mechanism 2 away from the shell 1 to the welding point. Under the action of the negative pressure suction component 33, a negative pressure space is formed inside the shell 1. External air carrying welding slag enters the interior of the shell 1 through the slag feeding mechanism 2.

[0039] After the welding slag enters the interior of the shell 1, some of the larger welding slags are separated from the air and fall directly to the bottom of the shell 1. The remaining welding slag moves with the air and is first blocked by an elastic filter component 31. The larger diameter welding slag is blocked on one side of the elastic filter component 31. After passing through one elastic filter component 31, the smaller diameter welding slag is blocked on the other side of the elastic filter component 31. Then, it is transported by the discharge mechanism 4 to the interior of the external collection device for unified transfer. This not only reduces the labor intensity of workers, but also ensures the quality of subsequent welding slag recycling. For example, it avoids the step of removing impurities and separating welding slag in the subsequent recycling and reuse process of industrial solid waste treatment plants.

[0040] After the device has been running for a period of time, since the welding slag is mostly irregularly shaped sheet or block material, it is easy to get stuck on the elastic filter component 31 after impacting it. Relevant technicians can set the operating cycle of the drive component 32 through the controller.

[0041] When the drive assembly 32 is running, the electric telescopic rod 322 extends, the rod body 321 drives the baffle 323 to move, the baffle 323 pushes the elastic filter assembly 31 to deform to one side, the electric telescopic rod 322 retracts, the elastic filter assembly 31 deforms to the other side, the elastic potential energy is released, and the welding slag stuck on the elastic filter assembly 31 is thrown out, thereby avoiding the clogging of the elastic filter assembly, ensuring the effectiveness of this welding slag treatment device, and reducing the frequency of maintenance of this device by relevant technicians.

[0042] In the above embodiment, the speed at which the electric telescopic rod 322 moves the baffle 323 via the rod body 321 is much smaller than the speed at which the elastic filter assembly 31 deforms. Therefore, the elastic potential energy can be released freely and fully without other interference, thereby obtaining a larger impact force.

[0043] In one embodiment of this application, such as Figure 3 and Figure 4 As shown, the elastic filter assembly 31 includes a plate component 311, a filter screen component 313, and a plurality of arc-shaped fasteners 314.

[0044] The plate component 311 is connected to the shell 1. The plate component 311 has a circular hole, and the inner wall of the circular hole has a groove 312. The filter screen component 313 is located in the circular hole, and its outer edge extends into the groove 312. Multiple arc-shaped fasteners 314 pass through the filter screen component 313 respectively, and the arc-shaped fasteners 314 are slidably connected to the filter screen component 313. The two ends of the arc-shaped fasteners 314 are respectively connected to the inner wall of the round hole.

[0045] In one embodiment of this application, such as Figure 3 and Figure 4As shown, the filter component 313 includes a filter screen 3131, a central plate 3132, and a plurality of spring plates 3133.

[0046] The filter screen 3131 has an arc-shaped cross-section, a central plate 3132 is located on the top of the filter screen 3131, and multiple spring plates 3133 are arranged in an array on the filter screen 3131.

[0047] As a possible alternative, in order to increase the elastic potential energy of the filter element 313, the filter 3131 may be made of a metal material with a certain degree of elasticity.

[0048] The outer edge of the filter screen 3131 extends into the groove 312, the outer wall of the filter screen 3131 abuts against the side wall of the groove 312, and the arc-shaped fastener 314 penetrates the filter screen 3131.

[0049] It is understandable that by setting the arc-shaped fixing member 314, the internal stress at the edge of the filter screen 3131 after deformation can be eliminated, so that the elastic potential energy of the filter screen component 313 can be fully released.

[0050] The outer edge of the filter screen 3131 extends into the groove 312, and the outer wall of the filter screen 3131 abuts against the side wall of the groove 312, which can prevent gaps from existing between the filter screen 3131 and the plate component 311 after deformation, so as to ensure the filtration effect of the elastic filter assembly 31.

[0051] Rod 321 passes through center plate 3132.

[0052] As a possible scenario, in order to further increase the elastic potential energy of the filter element 313, both ends of the spring plate 3133 can be extended to the edge of the filter 3131.

[0053] As another possible scenario, in order to ensure a tight connection between the filter screen 3131 and the center plate 3132 after multiple deformations, the two can be connected by the aforementioned arc-shaped fastener 314 structure, provided that there are no gaps, thereby eliminating the stress between the deformation of the filter screen 3131 and the connection between the center plate 3132.

[0054] Specifically, the baffle 323 in the drive assembly 32 applies a force to the center plate 3132, and the center plate 3132 causes the filter screen 3131 to slowly deform to the other side. The spring plate 3133 deforms and its elastic potential energy increases. When the elastic potential energy of the spring plate 3133 exceeds the maximum threshold, the spring plate 3133 causes the filter screen 3131 to suddenly deform, and the elastic potential energy of the spring plate 3133 is released, thereby forming an impact force that throws the welding slag attached to the filter screen 3131 off.

[0055] When the filter screen 3131 deforms, its edge moves along the arc-shaped fixing member 314, thereby releasing the stress at the edge of the filter screen 3131. This not only ensures that the elastic potential energy is fully released, but also prevents the filter screen 3131 from being damaged.

[0056] In one embodiment of this application, such as Figure 4 As shown, the plate component 311 includes an outer frame 3111, an inner frame 3112, and a slewing bearing 3113.

[0057] The slewing bearing 3113 is disposed between the outer frame 3111 and the inner frame 3112. The outer frame 3111 is connected to the housing 1, and the groove 312 is formed on the inner frame 3112.

[0058] In one embodiment of this application, such as Figure 3 As shown, the filter mechanism 3 also includes a rotating assembly 34, which includes a gear ring transmission component 341, a worm gear transmission component 342, and a drive motor 343.

[0059] Among them, the gear ring transmission component 341 is connected to the inner frame 3112, the worm gear transmission component 342 is connected to the gear ring transmission component 341, both ends of the worm gear transmission component 342 are rotatably connected to the inner wall of the housing 1, one end of the worm gear transmission component 342 penetrates the inner wall of the housing 1, the drive motor 343 is mounted on the housing 1, and the output shaft of the drive motor 343 is connected to one end of the worm gear transmission component 342.

[0060] It should be noted that the gear and ring gear transmission component 341 described in this embodiment includes two gears and two ring gears. The gears mesh with the ring gears, and the ring gears are connected to the inner frame 3112.

[0061] Specifically, while the elastic filter assembly 31 blocks welding slag, the rotating assembly 34 operates. The drive motor 343 drives the inner frame 3112 to rotate through the worm gear transmission component 342 and the gear ring transmission component 341. The inner frame 3112 rotates relative to the outer frame 3111 through the slewing bearing 3113. The inner frame 3112 drives the elastic filter assembly 31 to rotate at a constant speed.

[0062] Understandably, during the slag filtration process, the uniform rotation of the elastic filter component 31 allows each part of the filter screen 3131 to evenly meet the air and slag entering the housing 1, preventing the filter screen 3131 from becoming partially blocked in a short period of time, and further optimizing the filtration effect of the elastic filter component 31.

[0063] In one embodiment of this application, such as Figure 2 As shown, the discharge mechanism 4 includes an auger feeder 44 and two collection troughs 42.

[0064] The inner bottom wall of the housing 1 has two through slots 41, which are located on one side of the corresponding elastic filter component 31. Two collection troughs 42 are installed on the bottom wall of the housing 1 and are connected to the corresponding through slots 41. A material level sensor 43 is provided inside the collection trough 42. An auger conveyor 44 is installed at the bottom of the housing 1, and the two collection troughs 42 are connected to the auger conveyor 44 respectively.

[0065] Specifically, the welding slag blocked by the elastic filter component 31 enters the interior of the collection tank 42 under the action of gravity. When the height of the welding slag inside the collection tank 42 exceeds the level sensor 43, the screw conveyor 44 operates to transport the welding slag in the collection tank 42 to the interior of the external collection device for temporary storage.

[0066] When the height of the welding slag inside the collection trough 42 is lower than that of the material level sensor 43, the screw conveyor 44 stops operating, causing the welding slag to accumulate in the collection trough 42.

[0067] It is understandable that by setting a material level sensor 43 inside the material collection tank 42, the bottom of the material collection tank 42 can always be filled with welding slag material, so that the material collection tank 42 is in a relatively closed state, preventing external air from entering the interior of the housing 1 through the discharge mechanism 4 to replenish the negative pressure space, and ensuring the slag suction effect of the slag feeding mechanism 2.

[0068] In one embodiment of this application, such as Figure 1 , Figure 5 and Figure 6 As shown, the slag feeding mechanism 2 includes a slag feeding assembly 21, a pipe body 22, and a slag removal component 23.

[0069] The slag inlet assembly 21 is mounted on the housing 1, one end of the pipe 22 is connected to the slag inlet assembly 21, and the other end of the pipe 22 is connected to the slag removal component 23.

[0070] It should be noted that the slag removal component 23 may include a grinding wheel, adjustable handles on both sides, and two auxiliary wheels. When in use, relevant technicians can control the direction of travel of the two auxiliary wheels through the handles on both sides. The auxiliary wheels can roll along the welding path. The grinding wheel peels off the welding slag. Under the action of negative pressure, the welding slag enters the interior of the shell 1 through the pipe body 22 and the slag inlet component 21 for filtration.

[0071] Furthermore, the adjustable handles on both sides include a locking knob, the specific structure and working principle of which have been disclosed in existing technology, and therefore will not be described in detail here. The angle between the two handles can be adjusted according to the position of the weld and the actual use, without specific limitations, thereby expanding the applicability of the slag removal component 23.

[0072] It should be noted that the specific structure of the slag removal component 23 described in this embodiment can be referred to as follows: Figure 6This section only shows one embodiment of the slag removal component 23. The tube body 22 can also be used with a grinding wheel, sandblasting machine or auxiliary slag hammer to collect and process welding slag. Its specific structure and working principle have been disclosed in the prior art, so they will not be described in detail here.

[0073] In one embodiment of this application, such as Figure 1 , Figure 5 and Figure 6 As shown, the slag feeding assembly 21 includes a base 211, multiple extension pipes 212 and multiple rotary valves 213.

[0074] The base 211 is mounted on the housing 1 and extends into the interior of the housing 1, and multiple extension tubes 212 and multiple rotary valves 213 are respectively mounted on the base 211.

[0075] It should be noted that the rotary valve 213 in this embodiment can control the opening and closing of the extension tube 212. Its specific connection structure and working principle have been disclosed in the prior art, so they will not be described in detail here.

[0076] It is understandable that the installation of multiple extension pipes 212 and multiple rotary valves 213 indicates that the device can connect a corresponding number of pipes 22 and slag removal components 23. Each extension pipe 212 and rotary valve 213 does not affect the others, making the device suitable for multiple welding stations to perform welding slag treatment operations simultaneously, thereby improving the practicality of the device and expanding its application range.

[0077] In summary, the metal casting welding slag treatment device of this application embodiment drives the reciprocating movement of the drive component to cause deformation of the elastic filter component. The release of elastic potential energy brings a large impact force to throw out the welding slag stuck on the surface of the elastic filter component, thereby avoiding the blockage of the elastic filter component 31, ensuring the effectiveness of the welding slag treatment device, and reducing the frequency of maintenance of the device by relevant technicians.
