Description
A scrap iron recycling device Technical Field
[0001] This utility model relates to the field of ductile iron processing technology, and in particular to a waste iron scrap recycling device. Background Technology
[0002] Ductile iron is a type of cast iron material with a unique microstructure, obtained by adding spheroidizing agents and inoculants to ordinary cast iron, followed by spheroidizing and inoculation treatments. Ductile iron has rapidly developed into the second most widely used cast iron material after gray cast iron. The concept of "replacing steel with iron" primarily refers to ductile iron. The machining of ductile iron parts generates a significant amount of waste material, which can be recycled.
[0003] For example, patent CN210876544U discloses a waste iron scrap recycling device for ductile iron castings, including a cleaning tank, a feeding hopper, a top plate, a mounting plate, a filter screen, and an electric telescopic rod. This device removes residual oil from the surface of the recycled scrap, facilitating its subsequent utilization. It is also easy to operate and readily applicable.
[0004] The aforementioned patented scrap metal recycling device involves directly feeding scrap metal into the washing tank through a hopper. However, the scrap metal may contain other impurities, which can affect the washing effect. Furthermore, the filter screen in the device is fixed. With continuous use, the filter screen will inevitably become clogged with scrap metal and other impurities over long-term operation. Once clogged, the drainage efficiency of the filter pipe will be severely reduced, thus affecting the smooth operation and efficiency of the entire recycling device. Therefore, a scrap metal recycling device needs to be designed. Summary of the Invention

[0024] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0025] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.
[0026] Referring to Figures 1 to 4, this embodiment of the present invention provides a waste iron filings recycling device, including a cleaning component 1. The cleaning component 1 includes a cleaning tank 11, which is used to store waste iron filings. A water inlet pipe 12 is connected to the upper part of the cleaning tank 11, which is adapted to supply water into the cleaning tank 11. A drain pipe 13 is connected to the lower part of the cleaning tank 11, which is used to discharge wastewater from the cleaning tank 11.
[0027] It should be noted that valves are installed in both the inlet pipe 12 and the drain pipe 13 to control the opening and closing of the inlet pipe 12 and the drain pipe 13.
[0028] A cover plate 14 is installed on the cleaning tank 11 by fasteners, and a motor 15 is fixedly installed on the cover plate 14. The output end of the motor 15 is provided through the cover plate 14, and an agitator 16 is fixedly installed on the output end of the motor 15. The agitator 16 is adapted to rotate with the output end of the motor 15.
[0029] When in use, put the scrap iron filings to be recycled into the cleaning tank 11, and then open the valve on the water inlet pipe 12. External water flows into the cleaning tank 11 through the water inlet pipe 12, forming a certain level of cleaning water in the tank to meet the needs of cleaning scrap iron filings.
[0030] Next, the motor 15 on the cover plate 14 is started. After the motor 15 is powered on, its output end begins to rotate, driving the stirring blade 16 fixedly installed at the output end to rotate together. The stirring blade 16 rotates at high speed in the cleaning tank 11, stirring and mixing the scrap iron filings and cleaning water in the tank. Under the stirring action, the cleaning water can come into more thorough contact with the scrap iron filings, washing away the oil, dust and other impurities attached to the surface of the scrap iron filings, thus realizing the cleaning operation of the scrap iron filings.
[0031] After the cleaning work is completed, turn off the motor 15 and then open the valve on the drain pipe 13. The wastewater containing impurities in the cleaning tank 11 is discharged through the drain pipe 13. As the wastewater is gradually discharged, the cleaned scrap iron filings remain in the cleaning tank 11 for further recycling and processing.
[0032] A filter assembly 2 is connected and installed on the cleaning tank 11. The filter assembly 2 includes a connecting pipe 21 connected and installed on the cleaning tank 11, and a hopper 22 connected and installed on the connecting pipe 21. A hinge 23 is fixedly installed on the side of the hopper 22, and a filter screen 24 is fixedly installed on the movable end of the hinge 23. The filter screen 24 is in a horizontal state by default, and the filter screen 24 is suitable for filtering the scrap iron filings entering the cleaning tank 11 so as to filter out larger impurities in the scrap iron filings.
[0033] A baffle 25 is fixedly installed on the side of the filter screen 24 away from the hopper 22. The baffle 25 is adapted to block the scrap iron filings poured into the filter screen 24.
[0034] When scrap iron filings are fed into the washing tank 11, the scrap iron filings enter the washing tank 11 through the hopper 22. When the scrap iron filings fall onto the filter screen 24 through the hopper 22, larger impurities mixed in with them, such as oversized stones, wood blocks or other metal foreign objects, will be intercepted on the filter screen 24 because they cannot pass through the mesh of the filter screen 24.
[0035] Scrap iron filings that meet the size requirements can pass through the mesh and continue into the washing tank 11 via the connecting pipe 21, thus performing preliminary screening of the scrap iron filings and ensuring that the scrap iron filings entering the washing tank 11 are relatively pure. Meanwhile, the baffle 25 installed on the filter screen 24 effectively prevents the scrap iron filings from scattering when being poured out. When scrap iron filings are poured from the hopper 22 into the filter screen 24, the baffle 25 prevents the scrap iron filings from accidentally falling off the edge of the filter screen 24. This not only prevents the waste of scrap iron filings;
[0036] Meanwhile, docking plates 26 are fixedly installed on both sides of the filter screen 24, and two sets of side plates 27 are fixedly installed on both sides of the hopper 22. Fixing units are also installed on both sides of the hopper 22. The fixing unit includes a fixing seat 28 fixedly installed on the side plate 27, a rotating shaft 29 is movably installed on the fixing seat 28, and a threaded groove (not shown in the figure) is opened at one end of the rotating shaft 29. At the same time, an opening groove (not shown in the figure) adapted to the diameter of the rotating shaft 29 is opened on the docking plate 26. The two sets of vertically arranged opening grooves are arranged opposite each other (refer to Figure 3), and a spiral part 210 is threadedly connected to one end of the rotating shaft 29.
[0037] Furthermore, a handle 211 is fixedly installed on the side of the baffle 25. The handle 211 facilitates the rotation of the filter screen 24, so as to dispose of the impurities accumulated on the filter screen 24.
[0038] When filtering scrap iron filings is required, the filter screen 24 needs to be placed on the hopper 22. Since the filter screen 24 is fixed with docking plates 26 on both sides, and the hopper 22 is fixed with side plates 27 on both sides, and the side plates 27 are equipped with fixing seats 28 with rotating shafts 29, this provides the basic structure for subsequent fixing operations;
[0039] After placing the filter screen 24 horizontally on the hopper 22, rotate the rotating shaft 29. The rotating shaft 29 can move flexibly on the fixed base 28. When rotated to a suitable angle, the rotating shaft 29 will lock into the vertically arranged and opposite opening slot on the docking plate 26. The diameter of the opening slot is adapted to the rotating shaft 29, which ensures that the rotating shaft 29 can be smoothly engaged and initially restricts the partial horizontal movement of the filter screen 24.
[0040] After the rotating shaft 29 is engaged in the opening slot, the helical part 210, which is threaded to one end of the rotating shaft 29, is operated. By rotating the helical part 210, the threaded connection is utilized to move it along the rotating shaft 29 toward the mating plate 26. As the helical part 210 is continuously tightened, it gradually fits onto the mating plate 26.
[0041] When the spiral part 210 is tightly attached to the docking plate 26, a pressure is generated on the docking plate 26, which in turn fixes the filter screen 24 tightly to the hopper 22. During the process of the scrap iron filings falling onto the filter screen 24 through the hopper 22 for filtration, the filter screen 24 will not easily shake or shift, ensuring the stability and effectiveness of the filtration work.
[0042] When it is necessary to clean the impurities trapped on the filter screen 24 or to maintain or replace the filter screen 24, simply rotate the spiral part 210 in the opposite direction to separate it from the docking plate 26, and then rotate the rotating shaft 29 to disengage it from the opening slot, so that the filter screen 24 can be removed from the hopper 22.
[0043] Furthermore, a feeding assembly 3 is connected and installed on the cleaning tank 11. The feeding assembly 3 includes a feeding pipe 31 connected and installed on the cleaning tank 11. The feeding pipe 31 is a Y-shaped pipe. Here, one end of the Y-shaped pipe is defined as the discharge pipe 32, which is used to discharge the cleaned scrap iron filings. The other end of the Y-shaped pipe is defined as the filter pipe 33, and one end of the filter pipe 33 has a first flange 34.
[0044] A movable pipe 35 is connected to the first flange 34. The movable pipe 35 has a second flange at one end near the first flange 34. Bolts 36 are connected between the first flange 34 and the second flange. A screen 37 is fixedly installed inside the movable pipe 35. The screen 37 can prevent waste from being discharged from the filter pipe 33 with the wastewater. Valves are installed on both the filter pipe 33 and the movable pipe 35.
[0045] In this application, a sealing ring is provided between the second flange and the first flange 34 to improve the sealing performance of the connection between the filter tube 33 and the movable tube 35;
[0046] Once the cleaning process is complete, the wastewater and scrap iron filings in the cleaning tank 11 will flow to the Y-shaped discharge pipe 31 after the corresponding valves are opened. Due to gravity and the flow of water, the wastewater will be discharged through the filter pipe 33. When the wastewater flows through the movable pipe 35, the screen 37 will filter the wastewater and intercept any residual scrap iron filings, preventing them from being discharged with the wastewater, thus achieving solid-liquid separation.
[0047] The cleaned scrap iron is discharged through discharge pipe 32, completing the transfer from cleaning tank 11 to the next recycling process.
[0048] The movable pipe 35 is connected to the filter pipe 33 via the first flange 34, the second flange, and bolts 36. This connection method allows for easy disassembly and installation of the movable pipe 35. When the screen 37 becomes clogged with scrap iron filings and impurities after prolonged use, the movable pipe 35 can be removed by unscrewing the bolts 36 to clean or replace the screen 37, and then it can be reinstalled to restore the normal operation of the device.
[0049] In summary: the waste iron filings entering the cleaning tank 11 are initially screened by the filter assembly 2. The waste iron filings fall onto the horizontal filter screen 24 through the hopper 22, where larger impurities are intercepted. Waste iron filings that meet the size requirements pass through the mesh and enter the cleaning tank 11 through the connecting pipe 21. Next, the waste iron filings to be recycled are placed into the cleaning tank 11, the water inlet valve 12 is opened, and external water flows in to form cleaning water. The motor 15 on the cover plate 14 is started, and the stirring blades 16 rotate, so that the cleaning water and waste iron filings are fully mixed, washing away surface impurities and completing the cleaning operation.
[0050] After cleaning, turn off motor 15 and open drain pipe 13 valve to discharge wastewater, leaving the cleaned scrap iron filings in the bucket. Then, open the corresponding valve of feeding assembly 3, and the wastewater and scrap iron filings flow to Y-shaped feeding pipe 31. The wastewater is discharged through filter pipe 33, and the screen 37 in movable pipe 35 filters the wastewater and intercepts scrap iron filings to achieve solid-liquid separation. The cleaned scrap iron filings are discharged through discharge pipe 32.
[0051] The filter assembly 2 can effectively filter larger impurities, ensuring that the scrap iron filings entering the cleaning tank 11 are relatively pure and reducing the impact of impurities on the cleaning effect; the stirring action of the stirring blade 16 improves the thoroughness of the cleaning and enhances the cleaning effect; the feeding assembly 3 realizes solid-liquid separation, preventing scrap iron filings from being discharged with wastewater and improving the recycling quality. At the same time, the movable pipe 35 can be easily disassembled and installed, making it easy to clean or replace the clogged screen 37, ensuring smooth operation of the device and improving work efficiency and maintainability.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
