[0002] With the development of industries such as aerospace and medical, the demand for titanium materials is increasing daily, greatly promoting the development of my country's titanium industry. However, this has also generated a large amount of titanium scrap and waste. Due to the unique processing technology of titanium and titanium alloys, the yield of titanium materials is relatively low, generally around 50%. The waste generated is mainly divided into block waste and chip waste (machining chips), with chip waste accounting for about 70% of the total waste. Therefore, how to achieve secondary processing and recycling of chip waste is of great research significance. Summary of the Invention

The synchronous rotation of the three sets of roller cutters is achieved through servo motor I and the three rotating shafts, and the cutting area is divided into four areas, including a feeding area, a granulation area and two discharge areas. The granulation area has a closed dart-shaped cross section, which is surrounded by the three sets of roller cutters.

[0011] Furthermore, each set of hobs includes a hob holder and several blades mounted along its circumference. The hob holder is designed with two oblique lines. The blades are made of SKD11 or DC53 material and, after heat treatment, have a hardness of HRC58-HRC60.

There are multiple abnormal part collectors arranged side by side above the conveyor belt.

[0014] Furthermore, the post-processing mechanism includes a mesh box, a conveyor belt, a travel shaft, a sliding shaft, and a cleaning device. An eccentric shaft is mounted on the mesh box and is suspended from the conveyor belt. The conveyor belt is connected to a servo motor II, and its opening, closing, and rotation speed are controlled by the servo motor II. The conveyor belt drives the mesh box to move horizontally. The eccentric shaft is connected to a servo motor III, which controls the rotation of the eccentric shaft, thereby rotating the mesh box. The top of the mesh box has an openable / closeable cover. The travel shaft and sliding shaft are respectively located above and below the conveyor belt. The travel shaft is positioned between the loading station and the closing station. At the loading station, the cover is opened to feed particles into the mesh box. At the closing station, the cover is closed via the travel shaft. At the dust removal station, the mesh box with the cover closed is dusted. The sliding shaft is located at the unloading station for automatic unloading.

[0015] Furthermore, the wire mesh cage is a cylindrical wire mesh cage made of PP material, and there is an eccentric shaft at R / 4 of the wire mesh cage, where R is the radius of the wire mesh cage; the dust removal station is equipped with several air nozzles for blowing air onto the wire mesh cage to remove dust.

[0016] Furthermore, the cleaning device includes an alkaline washing tank, an acid washing tank, a water washing tank, and a drying oven. The alkaline washing tank, acid washing tank, water washing tank, and drying oven are all located below the conveyor belt. The alkaline washing tank is located between the ash removal station and the unloading station. The acid washing tank is located between the alkaline washing tank and the unloading station. A water washing tank and a drying oven are sequentially arranged between the alkaline washing tank and the acid washing tank along the travel direction.

[0017] This invention also discloses a method for recycling titanium scrap, which uses a titanium scrap recycling device as described above, and includes the following steps:

[0018] 1) Granulation: The waste material is granulated into small particles of uniform size through a granulation mechanism;

[0040] The present invention will now be described in detail so that its advantages and features can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0041] The following provides a brief overview of one or more aspects to offer a basic understanding of them. This overview is not an exhaustive summary of all conceived aspects, nor is it intended to identify key or decisive elements of all aspects, nor to define the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form to prepare for the more detailed descriptions that follow.

[0042] Example 1

[0043] like Figure 1-7 As shown, a titanium scrap recycling device includes:

[0044] The granulation unit is used to divide shavings of titanium waste into uniformly sized small titanium shavings, which may contain unwanted impurities.

[0045] The pretreatment unit is used to pre-treat the small titanium shavings separated by the granulation unit to remove iron foreign objects, abnormal color parts, etc. from the particles.

[0046] The post-processing unit is used to process the titanium shavings particles after the pre-processing unit. This includes loading, transportation, turning, dust removal, alkali washing, water washing, acid washing, spin drying / air drying, and unloading. The final product is clean, uniformly sized titanium shavings particles that can be used directly as raw materials for ingot smelting.

[0047] The granulation mechanism mainly includes a granulation component 1, which includes three sets of roller cutters. The roller cutters are detachable. Each set of roller cutters includes a roller cutter fixing seat 2 and several blades 3 installed along its circumference. The roller cutter fixing seat 2 is designed with two oblique lines, which effectively picks up titanium chips while also having a certain extrusion and polymerization effect on the titanium chips. The blades 3 are made of SKD11 or DC53 material. After heat treatment, the hardness is between HRC58 and HRC60, which ensures rigidity while retaining a certain impact toughness, and can quickly and effectively cut titanium chips. A set of roller cutters is installed on each of the stellar rotation shaft 4, planetary rotation shaft 5, and granulation rotation shaft 6. The stellar rotation shaft 4, planetary rotation shaft 5, and granulation rotation shaft 6 are connected to servo motor I (not shown) through transmission gears. The opening, closing, speed, and direction of the stellar rotation shaft 4, planetary rotation shaft 5, and granulation rotation shaft 6 are all controlled by servo motor I. The three sets of roller cutters are controlled to rotate synchronously with each other through the three sets of rotation shafts (stellar rotation shaft 4, planetary rotation shaft 5, and granulation rotation shaft 6) and servo motor I. The titanium chip cutting area is effectively divided into four areas: a feeding area 7, a granulation area 8, and two discharge areas 9. The cross-section of the granulation area is a closed dart shape, which is surrounded by the three sets of roller cutters. During feeding and discharging, titanium chips are fed in and discharged under the pressure of gravity and the roller cutter fixing seat 2. During granulation, the stellar rotating shaft 4, the planetary rotating shaft 5, the granulation rotating shaft 6, and the three sets of roller cutters form a dart-shaped closed area. Under the action of the three sets of roller cutters, the titanium chips are continuously turned, squeezed, and cut, and are eventually divided into small titanium chip particles of uniform size.

[0048] When the diameter of the hobbing cutter is around 200mm, it can process 300KG of titanium shavings per hour into small titanium shaving particles of 5mm-13mm, basically reaching the particle size level of high-quality sponge titanium (grade 0 and 0A). The size of the crushed titanium shaving particles shows a clear normal distribution, with 80% of the particles being around 9mm in size.

[0049] To ensure the stability of the granulation component 1, the granulation component 1 is placed on the fixed base 1-1. The top of the fixed base 1-1 has a funnel-shaped opening 1-11 to facilitate rapid feeding. The titanium chips to be cut enter the feeding area 7 of the granulation component 1 through the funnel-shaped opening 1-11. Under the action of three sets of roller cutters and three sets of gears, the titanium chips are continuously turned, squeezed and cut, and finally divided into small titanium chip particles of uniform size. Then, they flow out through the matching screen 1-12 below the granulation component 1.

[0050] The pretreatment mechanism includes a conveyor belt 10, a scraper 11, a magnetic adsorber 12, a color anomaly detector 13, and an abnormal part collector 14. The scraper 11, magnetic adsorber 12, color anomaly detector 13, and abnormal part collector 14 are sequentially arranged above the conveyor belt 10. The scraper 11 primarily ensures that the titanium particles are evenly spread on the conveyor belt 10. The magnetic adsorber 12 primarily adsorbs iron-like foreign objects present in the titanium particles. The color anomaly detector 13 is mainly used to mark the location of the abnormal titanium particles and instruct the abnormal part collector 14 to pick up the corresponding abnormal part. There are multiple abnormal part collectors 14, arranged side-by-side above the conveyor belt 10. During operation, they do not need to be moved; the abnormal part collector 14 at the corresponding location is activated based on the location of the abnormal part. After the titanium shavings are crushed and divided by the granulation mechanism, many uniformly sized titanium particles are obtained. These titanium particles fall onto the conveyor belt 10, which conveys the titanium particles at a speed of 3-10 m / min. After passing through the scraper 11, the magnetic adsorber 12, the color abnormality judge 13, and the abnormal part collector 14 in sequence, the titanium particles are obtained as titanium shaving particles that have been freed from impurities such as iron foreign matter and titanium shavings with abnormal color.

[0051] The post-processing mechanism includes a mesh cage 15, a conveyor belt 17, a travel shaft 19, a sliding shaft 21, an alkaline washing tank 22, an acid washing tank 23, a water washing tank 24, and a drying oven 25. The mesh cage 15 is a cylindrical mesh cage made of PP material. An eccentric shaft 16 is located at R / 4 of the mesh cage 15, where R is the radius of the mesh cage 15. The eccentric shaft 16 is mounted on the conveyor belt 17, which is connected to a servo motor II (not shown), and its opening, closing, and speed are controlled by the servo motor II. The conveyor belt 17 drives the mesh cage 15 to move horizontally. The eccentric shaft 16 is connected to a servo motor III (not shown), and the servo motor III controls the eccentric shaft 16. The rotation causes the mesh box 15 to rotate. The top of the mesh box 15 is equipped with a cover 18 that can be opened or closed. At the loading station, the cover 18 is opened to load materials. At the dust removal station, several air nozzles 20 are provided to blow air to remove dust from the mesh box 15 after the cover 18 is closed. The stroke shaft 19 and the sliding shaft 21 are respectively located above and below the conveyor belt 17. The stroke shaft 19 is located between the loading station and the closing station. The alkaline washing box 22, acid washing box 23, water washing box 24 and drying box 25 are located below the conveyor belt 17. At the unloading station, the sliding shaft 21 is provided to open the cover 18 to achieve automatic unloading.

[0052] At the loading station, titanium shavings are pre-treated by the pretreatment mechanism and then conveyed into the mesh box 15 by the conveyor belt 10. When the mesh box 15 is full, it moves horizontally to the closing station under the action of the conveyor belt 17. The cover 18 touches the travel shaft 19, the cover 18 closes, and the mesh box 15 is sealed. Then, the mesh box 15 rotates 180° under the action of the servo motor III and moves horizontally to the dust removal station driven by the conveyor belt 17. Dust is removed by 2-4 air nozzles 20. Then, it undergoes alkali washing, water washing, spin drying / air drying, acid washing, water washing, spin drying / air drying, and finally reaches the unloading station. The cover 18 opens, and the material is automatically unloaded under the action of the travel shaft 21, producing clean and uniformly sized titanium shavings, which can be used directly as raw materials for ingot smelting.

[0053] The alkaline washing solution is formulated as follows:

[0054] Sodium hydroxide (NaOH), 300–350 g / L

[0055] Ammonia water (NH3·H2O), 200~250ml / l

[0056] Sodium nitrite (NaNO2), 200–220 g / L

[0057] Isopropyl ketone (C3H6O), 20 ml / L

[0058] Water, remaining amount.

[0059] The alkaline washing temperature is 130-135℃.

[0060] The alkaline washing time is 15-20 minutes.

[0061] The main purpose of this alkaline washing process is to soften, loosen, emulsify, and disperse oxides, oil, or other impurities on the surface of small titanium scrap particles.

[0062] Oxides: Titanium alloys easily form a dense oxide film in the air. This oxide film not only reduces the corrosion resistance of titanium alloys, but also has an adverse effect on subsequent processing.

[0063] Oil stains: Lubricants or cutting fluids are often used during the manufacturing and processing of titanium alloys. These lubricants or cutting fluids can leave oil stains on the surface of the titanium alloy, which will affect the surface quality of the titanium alloy if not removed in time.

[0064] Other impurities: In addition to oxides and oil stains, other impurities such as dust and metal particles may also exist on the surface of titanium alloys. These impurities will reduce the surface finish and overall quality of the titanium alloy.

[0065] Alkaline washing is carried out in alkaline washing tank 22, which can be equipped with heating and temperature control devices, such as electric heaters, which can be purchased directly.

[0066] The pickling solution is formulated as follows:

[0067] Nitric acid (HNO3, 65% / 68%), 150–200 ml / L

[0068] Hydrofluoric acid (HF, 40%), 20–30 ml / L

[0069] Sulfuric acid (H2SO4), 5–10 ml / L

[0070] Ferric chloride (FeCl3), 5 g / L

[0071] Water, remaining amount.

[0072] The pickling temperature is 20-30℃.

[0073] Pickling time is 1 to 2 minutes.

[0074] The pickling process is mainly for removing oxides from the surface of titanium chips.

[0075] Pickling is carried out in pickling tank 23. Because the titanium scrap will gradually heat up during the pickling process and the temperature changes frequently, heating, cooling and temperature control devices, such as electric heaters and condensers, are installed in pickling tank 23, which can be purchased directly.

[0076] During acid washing, alkali washing, and water washing, the amount of small titanium shavings packed in the box should not exceed 2 / 3 of the volume, and compressed air can be used to agitate the solution during operation.

[0077] During pickling, the pickling time must be strictly controlled to prevent excessive hydrogen absorption by titanium and its alloys and avoid abnormal composition.

[0078] The washing is carried out in the washing tank 24, and the spin drying / air drying is carried out in the drying oven 25.

[0079] A water washing tank 24 and an oven 25 are sequentially arranged between the alkaline washing tank 22 and the acid washing tank 23.

[0080] A water washing tank 24 and a drying oven 25 are sequentially arranged between the pickling tank 23 and the unloading station.

[0081] like Figure 7 As shown, a method for recycling titanium scrap includes the following steps:

[0082] 1) Granulation: The granulation mechanism separates the shavings of titanium waste into small titanium shavings of uniform size. These shavings may contain unwanted impurities.

[0083] 2) Material selection: The titanium shavings particles separated by the granulation unit are pre-treated by the pre-treatment unit to remove impurities such as iron foreign objects and abnormal color parts from the particles;

[0084] 3) Loading: At the loading station, open the cover 18 of the mesh box 15 and send the particles obtained in step 2) into the mesh box 15 via the conveyor belt 10.

[0085] 4) Closing the bin: After the net cage 15 is full of small particles, it moves horizontally to the closing position under the action of the conveyor belt 17. The cover 18 touches the travel shaft 19, the cover 18 closes and locks, and the net cage 15 is sealed.

[0086] 5) The mesh cage 15 rotates 180° under the action of the servo motor Ⅲ, and moves horizontally to the dust removal station under the action of the conveyor belt 17, where the dust is removed by 2-4 air nozzles 20.

[0087] 6) The wire mesh cage 15 can be rotated to undergo alkaline washing in the alkaline washing tank 22;

[0088] 7) The net cage 15 is washed in the water washing tank 24 located between the alkaline washing tank 22 and the acid washing tank 23;

[0089] 8) The wire mesh cage 15 is spun dry / air dried in the drying oven 25 located between the alkaline washing box 22 and the acid washing box 23;

[0090] 9) The wire mesh cage 15 is pickled in the pickling tank 23;

[0091] 10) The mesh cage 15 is washed in the washing tank 24 located between the pickling tank 23 and the unloading station;

[0092] 11) The wire mesh cage 15 is spun dry / air dried in the drying oven 25 located between the pickling tank 23 and the unloading station;

[0093] 12) When the mesh cage 15 reaches the unloading station, the mesh cage 15 rotates and is inverted, the box cover 18 faces down and is opened, and the material is automatically unloaded under the action of the sliding shaft 21, producing clean and uniformly sized titanium shavings, which can be used directly as raw materials for ingot smelting.

[0094] During alkaline washing, acid washing, and water washing, the mesh box 15 can perform pendulum-like repeated motion or even spin motion under the action of the servo motor III, which fully agitates the small titanium shavings in the mesh box 15, so that these particles are thoroughly and evenly washed.

[0095] For parts or structures not specifically described in this invention, such as servo motor I, servo motor II, servo motor III, alkaline washing tank 22, acid washing tank 23, water washing tank 24, drying oven 25, heating, cooling, and temperature control devices, existing technologies or products can be used, and will not be elaborated here. Servo motor I, servo motor II, and servo motor III can be connected to and controlled by a microcontroller or PLC, etc., to realize human-machine interaction and intelligent remote control.

[0096] This invention can be extended from titanium scrap recycling to the recycling of other metal residues and wastes, demonstrating high versatility.
