Description

Technical Field

[0001] This invention relates to the field of valve manufacturing technology, and more specifically, to a metal scrap repositioning and cleaning device for valve processing. Background Technology

[0002] Large gate valves are widely used in drilling and other fields. Due to their large size and weight, the cleaning process after precision machining presents significant challenges. Valve surfaces typically retain cutting slag, metal chips, and oil contaminants such as rust-preventive oil and cutting oil, which need to be thoroughly removed to meet subsequent assembly or usage requirements.

[0003] The most common cleaning method currently is manual rinsing with a handheld water gun. While water gun rinsing can wash away some of the attached iron slag, it is often difficult to effectively remove stubborn oil stains adhering to the valve surface by simply relying on the impact of water flow, resulting in unsatisfactory cleaning results.

[0004] To improve the cleaning ability of oil stains, another method is to use ultrasonic cleaning. Utilizing the cavitation effect generated by ultrasound in the cleaning fluid, oil stains on the valve surface can be effectively removed. However, after ultrasonically cleaning several valves, metal debris and slag detached from the valves during the cleaning process gradually accumulate in the cleaning tank. These debris not only contaminate the cleaning fluid but may also clog the circulation pipes or transducer gaps in the cleaning tank, reducing the efficiency of ultrasonic cleaning and even affecting the stability of the cleaning effect on subsequent valves. Frequent changes to the cleaning fluid or shutdowns to clean debris from the bottom of the tank increase operating costs and maintenance time. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a metal shavings replacement and cleaning device for valve processing, which solves the problem that the existing cleaning methods cannot effectively remove oil stains and that waste shavings easily contaminate the cleaning tank.

[0006] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a metal scrap repositioning and cleaning device for valve processing, comprising: a frame; an ultrasonic cleaning tank installed on the frame; a mobile collection cart disposed on one side of the ultrasonic cleaning tank; a repositioning mechanism including a traveling component and a lifting component, the traveling component being movable along the frame and capable of switching between a first workstation and a second workstation, the first workstation being located above the ultrasonic cleaning tank and the second workstation being located above the mobile collection cart; the lifting component being installed on the traveling component and capable of vertically raising and lowering; a filter barrel detachably connected to the lower part of the lifting component, the filter barrel having an internal space for accommodating valves, and a filter plate assembly disposed on its barrel wall, the bottom of the filter barrel being provided with an openable baffle; and a baffle control mechanism disposed between the lifting component and the filter barrel, for controlling the baffle to open when the filter barrel moves to the second workstation.

[0007] According to one embodiment of the present invention, the walking assembly includes a walking frame and a drive module. The top of the frame is provided with a slide rail and a rack. The walking frame is mounted on the slide rail by a slider. The drive module is mounted on the walking frame and has a gear that is connected to the rack for transmission.

[0008] According to one embodiment of the present invention, the lifting assembly includes a support frame, a lifting frame, a lead screw module, and a sinking frame. The support frame is installed on the walking assembly, the lifting frame is slidably installed in the support frame, the lead screw module is disposed on the support frame and drives the lifting frame to rise and fall, the sinking frame is fixed to the bottom of the lifting frame, and the filter bucket is detachably connected to the bottom of the sinking frame.

[0009] According to one embodiment of the present invention, a suspension assembly is provided at the bottom of the sinking frame, and a hanging rod is provided at the top of the filter bucket. The suspension assembly includes a hook and a limiting hook hinged to the hook. The hanging rod is hung on the hook and limited by the limiting hook.

[0010] According to one embodiment of the present invention, the baffle control mechanism includes an electromagnet, a magnetic block, a pull rod, and a hinge rod; the electromagnet is mounted on the lower part of the lifting assembly via a bracket, the magnetic block is connected to the top end of the pull rod, the pull rod is vertically slidably mounted on the frame of the filter barrel, one end of the hinge rod is hinged to the lower end of the pull rod, and the other end is hinged to the baffle; when the electromagnet is energized, it attracts the magnetic block, causing the pull rod to move upward, and the baffle is opened by pulling the hinge rod.

[0011] According to one embodiment of the present invention, a hinge block is provided at the bottom of the frame body of the filter barrel, the baffle is hinged to the bottom of the frame body through the hinge block, and the inner side of the baffle is hinged to the hinge rod through another hinge block.

[0012] According to one embodiment of the present invention, the filter plate assembly includes a first filter plate and a second filter plate arranged adjacent to each other, and both the first filter plate and the second filter plate are provided with through holes for the cleaning fluid to pass through.

[0013] According to one embodiment of the present invention, the mobile collection vehicle includes a vehicle body, a collection hopper disposed on the top of the vehicle body, and a collection barrel disposed inside the vehicle body, wherein the outlet of the collection hopper is aligned with the inlet of the collection barrel; the frame is provided with a passageway for the mobile collection vehicle to move in and out.

[0014] According to one embodiment of the present invention, there are two ultrasonic cleaning tanks and two sets of switching mechanisms. Each set of switching mechanisms corresponds to one ultrasonic cleaning tank and one mobile collection vehicle. The two sets of switching mechanisms can work independently or alternately.

[0015] According to one embodiment of the present invention, there are two sets of the switching mechanism. The two sets of switching mechanisms share an ultrasonic cleaning tank and a mobile collection vehicle. The two sets of switching mechanisms alternately perform cleaning and unloading.

[0016] In summary, this application includes at least one of the following beneficial technical effects: 1. In this invention, the use of an ultrasonic cleaning tank in conjunction with a filter can effectively clean oil stains from valves. At the same time, metal slag and other metal debris that fall off during cleaning are trapped in the filter and will not enter the cleaning tank, thus preventing the cleaning tank from being contaminated or blocked. This allows the ultrasonic cleaning tank to continuously clean multiple valves, ensuring stable cleaning results.

[0017] 2. In this invention, the filter barrel is moved between the cleaning station and the unloading station by means of the cooperation of the walking component and the lifting component. After cleaning, there is no need for manual slag removal or cleaning of the cleaning pool. The filter barrel can be directly moved to the top of the mobile collection vehicle for unloading. The operation is simple and improves the automation and efficiency of the cleaning operation.

[0018] 3. In this invention, the opening and closing of the baffle at the bottom of the filter barrel is controlled by a linkage mechanism composed of an electromagnet and a pull rod magnet. The structure is simple and the operation is reliable. When the power is off, the pull rod can automatically reset under the action of gravity to close the baffle, which is convenient for the next use. In addition, the mobile collection vehicle can centrally transport the collected debris, reducing on-site cleaning work. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1, see Figure 1This embodiment provides a metal shavings transfer and cleaning device for valve processing, which solves the problems of difficult oil removal and easy contamination of the ultrasonic cleaning tank by waste shavings during the cleaning of existing large gate valves. It includes a frame 1, on which a transfer mechanism 2 and an ultrasonic cleaning tank 5 are mounted, and the ultrasonic cleaning tank 5 is fixedly installed on the frame 1. A mobile collection cart 4 is provided on one side of the ultrasonic cleaning tank 5, and the frame 1 has a passageway for the mobile collection cart 4 to enter, exit, and move out. The transfer mechanism 2 is located above both the ultrasonic cleaning tank 5 and the mobile collection cart 4, and the transfer mechanism 2 can move between at least two workstations. In this embodiment, the transfer mechanism 2 is configured to move between two workstations: when the transfer mechanism 2 moves above the ultrasonic cleaning tank 5, it is the first workstation; when the transfer mechanism 2 moves above the mobile collection cart 4, it is the second workstation.

[0023] See Figure 1 and Figure 2 The top of the frame 1 is equipped with a slide rail, and at least one side of the slide rail is also equipped with a rack. The switching mechanism 2 includes a traveling component 21 and a lifting component 22, with the lifting component 22 being mounted entirely on the traveling component 21. The bottom of the traveling frame 211 of the traveling component 21 is mounted on the slide rail at the top of the frame 1 via a slider. A drive module 212 is also mounted on the traveling frame 211. The drive module 212 has a gear connected to the rack and pinion drive and can be composed of a motor and a reducer. When the drive module 212 is started, the traveling component 21 can move along the slide rail, thereby switching between the first and second workstations. During valve cleaning, the valve is lifted entirely by a sling. The traveling component 21 and the lifting component 22 have a passageway in the Z-axis direction for the valve to pass through. (See reference...) Figure 2 The passageway is the central space of the frame containing the walking assembly 21 and the lifting assembly 22.

[0024] Further, see Figure 3 and Figure 4 The bottom of the lifting assembly 22 is equipped with a filter bucket 3. The lifting assembly 22 includes a support frame 221 installed on the central passage of the traveling frame 211. The lifting frame 222 is slidably installed on the central passage of the support frame 221 and can move along the Z-axis. A sinking frame 224 is installed at the bottom of the lifting frame 222, and the bottom of the sinking frame 224 is connected to the filter bucket 3. A hanging rod 36 is provided at the top of the frame body of the filter bucket 3, and a suspension assembly 225 is installed at the bottom of the sinking frame 224. Through the connection between the suspension assembly 225 and the hanging rod 36, the filter bucket 3 is hoisted as a whole under the lifting assembly 22. A screw module 223 is installed on the support frame 221. The screw module 223 is driven by a motor, and its nut block is fixedly connected to one side of the lifting frame 222. Activating the screw module 223 can drive the lifting frame 222 to rise or fall as a whole, thereby driving the filter bucket 3 to rise or fall.

[0025] Filter bucket 3 is used to contain the valves and trap metal debris generated during cleaning. (See also...) Figure 5 and Figure 6 A filter plate assembly 31 is installed on the frame body of the filter bucket 3. The filter plate assembly 31 includes a first filter plate 311 and a second filter plate 312 arranged adjacent to each other. Both the first filter plate 311 and the second filter plate 312 have several through holes. The size of the through holes is designed to allow the cleaning fluid to pass freely while blocking metal debris larger than that size inside the bucket. A hanging rod 36 is set on the top of the frame body. A baffle 34 is hinged to the bottom of the frame body on the side of the first filter plate 311 via a hinge block 35. The baffle 34 can be flipped outward around the hinge point. A hinge rod 33 is hinged to the inner side of the baffle 34 via another hinge block 35. The other end of the hinge rod 33 is hinged to the lower end of the pull rod 32. The top of the pull rod 32 is slidably installed on the top of the frame body along the Z-axis direction via a bushing. A magnet block 321 is fixed to the top of the pull rod 32.

[0026] See Figure 7 and Figure 8 The lower part of the sunken frame 224 is a support beam 2241, and the suspension assembly 225 is installed on the support beam 2241. Specifically, the suspension assembly 225 includes a hook 2251 and a limiting hook 2252 hinged to the hook 2251. In use, the hanging rod 36 of the filter barrel 3 is first hung on the hook 2251, and then the limiting hook 2252 is fastened around the hinge to the corresponding hanging rod 36. A positioning hole groove is left between the hook 2251 and the limiting hook 2252 for the hanging rod 36 to pass through, thereby reliably suspending the filter barrel 3 and preventing it from accidentally falling off.

[0027] An electromagnet 227 is also mounted on the middle of the support beam 2241 via a bracket 226. The attraction end of the electromagnet 227 is aligned vertically with the magnetic block 321. When the electromagnet 227 is energized, it generates magnetic force that attracts the magnetic block 321 upwards, causing the pull rod 32 to move upwards as a whole. Since the hinge rod 33 forms a linkage mechanism with the pull rod 32 and the baffle 34 respectively, when the pull rod 32 moves upwards, it pushes the baffle 34 to flip outwards around its hinge point with the bottom of the frame body. After the baffles 34 on both sides open, they form an inclined unloading surface. (See reference...) Figure 9 Waste materials can slide down the inclined surface of baffle 34. After unloading, electromagnet 227 is de-energized, the magnetic force disappears, and pull rod 32 slides down under its own weight and the weight of baffle 34. It then pulls baffle 34 inward to reset via hinge rod 33, restoring it to the closed state. This linkage structure is reliable and requires no additional power reset element.

[0028] See Figure 10The mobile collection vehicle 4, located at the second workstation, includes a vehicle body 41. A collection hopper 42 is mounted on the top of the vehicle body 41, and a collection barrel 43 is placed inside the vehicle body 41. The bottom outlet of the collection hopper 42 is aligned with the top opening of the collection barrel 43 to collect falling metal debris. The mobile collection vehicle 4 can be moved out along the aisle of the frame 1, facilitating the centralized transfer and processing of debris from the collection barrel 43.

[0029] The working principle and operation process of this embodiment are as follows: When the switching mechanism 2 is in the first position, the traveling assembly 21 is positioned above the ultrasonic cleaning tank 5. A sling lifts the valve to be cleaned into the Z-direction passageway of the switching mechanism 2, and the sling descends to send the valve through the passageway into the filter tank 3. Simultaneously, the screw module 223 is activated to lower the lifting assembly 22 along with the filter tank 3, immersing both the filter tank 3 and the valve in the cleaning solution of the ultrasonic cleaning tank 5. During operation, the cleaning solution generates a cavitation effect under the action of ultrasound, impacting and peeling the valve surface, effectively removing oil stains and loosely attached iron filings. The cleaning solution can circulate freely through the through holes of the filter plate assembly 31, while the peeled-off metal debris, being larger than the filter holes, is trapped inside the filter tank 3 by the first filter plate 311 and the second filter plate 312, preventing it from falling into the cleaning tank. This achieves oil stain cleaning while avoiding debris contamination or clogging of the cleaning tank.

[0030] After cleaning, the sling is raised to lift the valve away from the ultrasonic cleaning tank 5 and send it to the next station. The screw module 223 is activated to lift the filter bucket 3 along with the valve until the entire filter bucket 3 is above the cleaning tank surface. Then, the drive module 212 of the walking assembly 21 is activated to move the entire switching mechanism 2 from the first station to the second station, above the mobile collection cart 4. At the second station, the screw module 223 lowers the filter bucket 3 again above the inlet of the collection hopper 42. The electromagnet 227 is energized to open the baffle 34, allowing metal debris trapped inside the bucket to slide down the inclined surface of the baffle 34 and fall into the collection bucket 43 via the collection hopper 42. After unloading, the electromagnet 227 is de-energized, the pull rod 32 and the baffle 34 reset, and the filter bucket 3 can return to the first station with the switching mechanism 2, ready for the next cleaning operation.

[0031] Example 2, based on Example 1, provides a dual-station parallel cleaning scheme to further improve cleaning efficiency. Two ultrasonic cleaning tanks 5 are installed side-by-side on the frame 1, and two independent switching mechanisms 2 are correspondingly installed on the frame 1. The slide rails at the top of the frame 1 extend along the length direction, and the walking components 21 of the two switching mechanisms 2 are arranged one after the other on the same set of slide rails. Each walking component 21 has an independent drive module 212, enabling it to move independently and controllably along the slide rails.

[0032] Each ultrasonic cleaning tank 5 corresponds to a first workstation. On one side of the frame 1, a mobile collection vehicle 4 is provided for each ultrasonic cleaning tank 5, or a shared mobile collection vehicle 4 that can move along a ground track is provided. This shared mobile collection vehicle can move and park under any of the second workstations. This embodiment is illustrated by setting one mobile collection vehicle 4 for each ultrasonic cleaning tank 5: a second workstation is provided on the side of each ultrasonic cleaning tank 5 on the frame 1, and a mobile collection vehicle 4 is placed in each one.

[0033] Each switching mechanism 2 can move between its corresponding first station (i.e., above the corresponding ultrasonic cleaning tank 5) and second station (i.e., above the corresponding mobile collection vehicle 4). Its structural composition, the hoisting method of the filter barrel 3, and the baffle opening and closing mechanism are the same as in Embodiment 1, and will not be described again here.

[0034] During operation, the two switching mechanisms 2 can independently execute the cleaning and unloading processes without interference. For example, while one switching mechanism 2 is lowering a filter barrel 3 containing valves into the corresponding ultrasonic cleaning tank 5 for cleaning, the other switching mechanism 2 can simultaneously unload or reload new valves at the second station. This parallel operation at two stations significantly increases the overall cleaning capacity. Furthermore, since the two mechanisms share a common slide rail, anti-collision logic can be set in the control system, such as limiting the minimum safe distance between the two traveling components 21, or dividing each traveling component into priority movement zones to ensure operational safety.

[0035] Example 3 differs from Example 1 in that only one ultrasonic cleaning tank 5 is installed on the frame 1, but two sets of switching mechanisms 2 are provided. The two sets of switching mechanisms 2 share the ultrasonic cleaning tank 5 and perform cleaning and unloading operations in an alternating manner, thereby reducing the idle waiting time of the ultrasonic cleaning tank and improving its utilization rate.

[0036] Specifically, the slide rail at the top of the frame 1 is extended, and the walking components 21 of both sets of switching mechanisms 2 are installed on the same set of slide rails and are driven by their respective drive modules 212. The slide rail is divided into a first work station area (located directly above the ultrasonic cleaning tank 5) and a second work station area (located above the mobile collection vehicle 4). Considering that the two sets of switching mechanisms 2 cannot occupy the first work station area at the same time, a clearance area is also provided on the slide rail. This clearance area can be located between the first work station area and the second work station area, or at the extended end of the slide rail, for temporarily parking the switching mechanism that is not in the cleaning state.

[0037] One mobile collection vehicle 4 can be installed. The capacity of its collection hopper 42 and collection bucket 43 should be sufficient to receive the debris generated from two consecutive unloading operations, or to replace the empty bucket in time after it is full. The mobile collection vehicle 4 can move along the aisle of the frame 1 and be positioned below the second work station.

[0038] The alternating work process is as follows: Initially, the first switching mechanism 2 is located in the first workstation area, with its filter tank 3 containing the valve to be cleaned, which is then lowered into the ultrasonic cleaning tank 5 for cleaning. Meanwhile, the second switching mechanism 2 is located in the second workstation area, performing unloading operations or loading new valves. When the first switching mechanism 2 finishes cleaning, the lifting component 22 raises the filter tank 3 to a safe height. Subsequently, the traveling component 21 of the first switching mechanism 2 moves out of the first workstation area and into the second workstation area for unloading. Simultaneously, if the second switching mechanism 2 has completed unloading and loading, its traveling component 21 moves from the avoidance area or the second workstation area into the first workstation area, lowering the filter tank 3 and the new valve into the ultrasonic cleaning tank 5 to begin cleaning. After unloading, the first switching mechanism 2 can stop in the second workstation area or move into the avoidance area, awaiting the next cleaning cycle. In this way, the two switching mechanisms alternately use the same ultrasonic cleaning tank, allowing the cleaning operation to proceed almost continuously, reducing the idle time of the cleaning tank and achieving a high work cycle.

[0039] To prevent the two sets of walking components 21 from colliding on the slide rail, the control system can obtain the position of each walking component in real time based on position sensors or encoders, formulate alternating movement logic, and ensure that the other walking component has completely left the area before one walking component enters the first work station area.

[0040] In Example 4, as a further optimization of the above embodiments, the filter plate assembly 31 of the filter barrel 3 can be detachably connected to the frame body, for example, by bolts or quick-release clips. After long-term use of the device, if the through holes on the filter plate are blocked by fine debris, the filter plate can be removed separately for cleaning or replacement to restore the water permeability of the filter barrel without replacing the entire filter barrel.

[0041] In addition, an elastic sealing strip, such as an oil-resistant rubber strip, can be installed on the edge of the baffle 34 that contacts the bottom of the filter barrel 3 frame body to reduce the gap between the baffle and the barrel body when the baffle is closed, improve the interception effect of fine debris, and at the same time prevent the cleaning fluid from leaking out of the baffle gap in large quantities during the cleaning process, thus affecting the circulation flow field of the cleaning fluid.

[0042] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0043] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.
