Description

Technical Field

[0001] This invention relates to the field of titanium scrap processing technology, and more specifically, to a dehydration device for titanium alloy return material. Background Technology

[0002] Titanium scrap refers to waste titanium materials generated during the production process. These waste titanium materials can be reused to reduce raw material waste. Before reuse, titanium scrap needs to be cleaned to remove impurities such as metals, cutting fluid, carbon materials, oxides, water, and other impurities. For example, in the existing titanium and titanium alloy scrap recycling production line and method with publication number CN115846382A, titanium scrap needs to undergo crushing, cleaning, drying, sorting, and distribution processes before it can be reused. Before drying the titanium return material, it is necessary to dehydrate the cleaned titanium return material. The existing public technologies for dehydration treatment are as follows: one is (CN115846382A) relying on a dehydration tank (spiral dehydration tank), in which hot air generated by the heating box is introduced into the dehydration tank by a fan to dehydrate the titanium return material; the other is (such as the authorization announcement number CN104148360) placing the cleaned titanium return material in the work basket on a gravity drying tank for natural drying, where the moisture on the metal turning material drips off naturally under the action of gravity, and then placing it on an air-cutting drying tank for air-cutting drying.

[0003] In the two disclosed technologies mentioned above, the dehydration before drying relies on natural gravity combined with a spiral stirring structure or wind to initially separate the water adhering to the surface of the titanium return material from the titanium return material. During the separation process, because the titanium return materials are in contact with each other and cover each other, the water between the covering surfaces cannot be quickly separated from the return material. Furthermore, because the titanium return material is relatively concentrated, the dehydration effect is not ideal, which in turn affects the subsequent drying efficiency of the titanium return material. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a titanium alloy return material dehydration device that improves the processing efficiency of titanium return material.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0008] The rotating material handling component includes a fixed sleeve fitted onto a lifting rod, a connecting rod fixed to the outer circumference of the fixed sleeve, a straight sleeve fixed to the end of the connecting rod away from the fixed sleeve and facing the discharge end of the feed pipe, an arc-shaped guide hood with an outward-curving top fixed to the top of the straight sleeve, a centrifugal dispersion hood fixed to the bottom of the straight sleeve, an air guide hole opened on the centrifugal dispersion hood, the straight sleeve, the arc-shaped guide hood, and the centrifugal dispersion hood being arranged coaxially, and an inclined plate inclined along the tangent direction of the straight sleeve fixed to the outer circumference of the straight sleeve.

[0009] As a preferred embodiment of the present invention, a mounting bracket is fixed on the outer circular surface of the dehydration cylinder, and the mounting bracket is fixedly connected to the inner wall of the box by bolts. An air extraction pipe is fixed on the top of the cylinder cover, and the inlet end of the feed pipe and the outlet end of the air extraction pipe both penetrate the box and extend to the outside of the box.

[0010] As a preferred embodiment of the present invention, a discharge pipe communicating with the inner cavity of the dewatering cylinder is installed at the bottom of the dewatering cylinder. The discharge end of the discharge pipe is connected to the feed end of the return material lifting structure. An air guide pipe runs through the bottom of the dewatering cylinder. An annular air supply pipe is connected to the input end of the air guide pipe. The air guide pipe is arranged in an annular pattern at equal intervals on the conical surface at the bottom of the dewatering cylinder.

[0011] As a preferred embodiment of the present invention, the dehydration cylinder is fitted with an annular air guide sleeve that communicates with the annular heat conduction groove, and an air supply pipe that communicates with the inner cavity of the annular air guide sleeve passes through the annular air guide sleeve. The dehydration cylinder is provided with a limiting flange for installing the annular air guide sleeve.

[0012] As a preferred embodiment of the present invention, the top of the boom is mounted on the support frame by a first hexagonal nut, and a second hexagonal nut is installed on the boom at both the bottom and bottom positions of the straight sleeve. A bearing is sleeved on the boom below the first hexagonal nut, and the bottom end of the bearing abuts against the support frame. A limit key is fixed on the boom between the two second hexagonal nuts, and a keyway that mates with the limit key is provided on the inner circular surface of the straight sleeve.

[0013] As a preferred embodiment of the present invention, the return material lifting structure includes a guide pipe, a connecting pipe that communicates with the inner cavity of the guide pipe is fixed on the guide pipe, the end of the connecting pipe away from the guide pipe is connected to the discharge pipe, and an installation sleeve is fitted on the guide pipe, the installation sleeve being fixed to the inner wall of the box by bolts.

[0014] As a preferred embodiment of the present invention, a rotating shaft passes through the guide tube along the axial position. A servo motor with an output shaft fixed to one end of the guide tube and fixedly connected to the rotating shaft is fixed. A spiral fan blade is fixed on the outer circular surface of one end of the rotating shaft inside the guide tube. A feeding bend that communicates with the inner cavity of the guide tube is fixed at the top of the guide tube. A telescopic pipe extending to the feeding end of the tunnel drying furnace is fixed at the discharge end of the feeding bend.

[0015] As a preferred embodiment of the present invention, a discharge trough is fixed inside the box and below the discharge end of the tunnel drying furnace, and the discharge end of the discharge trough passes through the box and extends to the outside of the box.

[0016] As a preferred embodiment of the present invention, the inner arc of the arc-shaped flow guide is a quarter circle, and the diameter of the inner arc of the arc-shaped flow guide is less than or equal to one-half of the inner diameter of the centrifugal dispersion hood.

[0017] The advantages of this invention are:

[0018] 1. This invention installs a rotating material distribution component inside the dehydration drum, which is driven by the sprayed material. In conjunction with the high-temperature gas injection pipe and the air supply pipe, the titanium return material is splashed away by the rotating material distribution component and then thrown away again under the action of centrifugal force. This allows it to fully contact the hot air inside the dehydration drum, separating the moisture on the surface of the titanium return material. This ensures the dehydration effect of the titanium return material while improving the dehydration efficiency, thereby improving the cleaning efficiency of the titanium return material.

[0019] 2. This invention, through the obstruction of the rotating bulk material and the centrifugal throwing effect of the rotating bulk material, fully separates the titanium return materials that are in contact with each other, reducing the mutual contact and obstruction between the titanium return materials. This allows individual titanium return materials to be fully exposed to hot air and fully contact with the hot air. At the same time, the impact force is used to separate the moisture on the surface of the titanium return materials, improving the dehydration effect on the surface moisture of the titanium return materials and ensuring the cleaning effect of the titanium alloy return materials.

[0041] Example 1:

[0042] Please see Figure 1-14 Structural diagram; the present invention provides the following technical solution:

[0043] Specifically, it refers to a titanium alloy return material dewatering device, including a housing 1 and a controller 2 installed at one end of the housing 1. The housing 1 has an inspection door and a ventilation louver on the top of the housing 1 for heat dissipation during operation. Inside the housing 1, from left to right, a dewatering structure 3, a return material lifting structure 4, and a tunnel drying furnace 5 are installed in sequence. The discharge end of the dewatering structure 3 is connected to the inlet end of the return material lifting structure 4, and the discharge end of the return material lifting structure 4 is connected to the inlet end of the tunnel drying furnace 5.

[0044] The dehydration structure 3 includes a dehydration cylinder 301 and a cylinder cover 302. A support frame 303 is provided between the top of the dehydration cylinder 301 and the bottom of the cylinder cover 302. A feed pipe 304 passes through the dehydration cylinder 301 and is connected to the outlet end of the titanium return material cleaning unit. A high-temperature gas injection pipe 305 passes through the feed pipe 304 and is provided with a buffer chamber to buffer the input high-temperature and high-speed airflow, further accelerating the input airflow and increasing the flow rate during injection. The input end of the high-temperature gas injection pipe 305 is connected to... The hot air output end of the hot air blower (which consists of a blower, a heater, and a control circuit, and can adjust the working temperature and air volume) blows out high-speed, high-temperature gas, creating a negative pressure in the feed pipe 304. This allows the titanium return material to be smoothly input through the feed pipe 304 under the action of the pressure difference, and then sprayed onto the rotating material distribution component 306 under the action of the high-speed, high-temperature gas flow. The material diffuses under the obstruction of the rotating material distribution component 306, increasing the contact area with the hot air flow. The high-temperature gas injection pipe 305 is coaxially arranged with the feed pipe 304.

[0045] A hanging rod 319 is rotatably connected to the support frame 303. A rotating material distribution component 306 is installed on the hanging rod 319, which is directly opposite to the discharge end of the feed pipe 304. An annular heat-conducting groove 307 is provided on the dewatering cylinder 301, which is recessed into the inner cavity of the dewatering cylinder 301. A vent hole communicating with the inner cavity of the annular heat-conducting groove 307 is opened on the outer surface of the annular heat-conducting groove 307, which is used to transfer the hot air input into the annular heat-conducting groove 307 to the dewatering cylinder 301 through the vent hole, so as to dehydrate the titanium return material flowing through the outer surface of the annular heat-conducting groove 307.

[0046] The rotating bulk material component 306 includes a fixed sleeve 3061 sleeved on the lifting rod 319. A connecting rod 3062 is fixed on the outer circular surface of the fixed sleeve 3061. A straight sleeve 3063 facing the discharge end of the feed pipe 304 is fixed at the end of the connecting rod 3062 away from the fixed sleeve 3061. An arc-shaped guide hood 3064 with an outward-curving top is fixed at the top of the straight sleeve 3063. A centrifugal dispersion hood 3065 is fixed at the bottom of the straight sleeve 3063. An air guide hole 3066 is opened on the centrifugal dispersion hood 3065. The straight sleeve 3063, the arc-shaped guide hood 3064, and the centrifugal dispersion hood 3065 are arranged coaxially. An inclined plate 3067 inclined along the tangent direction of the straight sleeve 3063 is fixed on the outer circular surface of the straight sleeve 3063.

[0047] The inner arc of the arc-shaped guide hood 3064 is a quarter circle, and the cross-section of the centrifugal dispersion hood 3065 is two semicircles. The height of the centrifugal material outlet away from the central axis of the centrifugal dispersion hood 3065 is less than the radius height of the centrifugal dispersion hood 3065, which facilitates the centrifugal ejection of titanium return material from the centrifugal dispersion hood 3065. The inner arc diameter of the arc-shaped guide hood 3064 is less than or equal to half the inner diameter of the centrifugal dispersion hood 3065.

[0048] A mounting bracket 308 is fixed on the outer circular surface of the dewatering cylinder 301. The mounting bracket 308 is fixedly connected to the inner wall of the housing 1 by bolts. An exhaust pipe 309 is fixed on the top of the cylinder cover 302. The exhaust pipe 309 is connected to an exhaust fan, so that the dewatering airflow input into the dewatering cylinder 301 flows in a fixed direction to avoid the airflow becoming turbulent in the dewatering cylinder 301. The exhaust pipe 309 extracts the airflow containing moisture generated during the dewatering process to prevent water vapor from accumulating in the dewatering cylinder 301 and improves the dewatering effect on the titanium scrap return material. The feed end of the feed pipe 304 and the exhaust end of the exhaust pipe 309 both penetrate the housing 1 and extend to the outside of the housing 1. A discharge pipe 310 is installed at the bottom of the dewatering cylinder 301 and communicates with the inner cavity of the dewatering cylinder 301. The discharge end of the discharge pipe 310 is connected to the feed end of the return material lifting structure 4.

[0049] The top of the boom 319 is mounted on the support frame 303 via a first hexagonal nut 316. Another first hexagonal nut 316 is also installed on the boom 319 below the support frame 303 to limit the boom 319 from below, ensuring that the boom 319 does not jump up and down during transmission. Second hexagonal nuts 317 are installed on the boom 319 at the bottom and bottom of the straight sleeve 3063. A bearing 318 is fitted on the boom 319 below the first hexagonal nut 316, with the bottom end of the bearing 318 pressing against the support frame 303. A limit key is fixed on the boom 319 between the two second hexagonal nuts 317. A keyway that mates with the limit key is provided on the inner surface of the straight sleeve 3063 to fix the rotating bulk material component 306 on the boom 319, so that the rotating bulk material component 306 can rotate smoothly under the action of the ejected titanium return material.

[0050] The working principle of the titanium alloy return material dewatering device provided by this invention is as follows:

[0051] Working principle: After being cleaned and drained (due to gravity, the surface of the drained titanium alloy is covered with a water film or has small water droplets that cannot drip off naturally due to gravity), the titanium return material is fed into the feed pipe 304. Under the action of high-speed, high-temperature gas ejected from the high-temperature gas jet pipe 305, it is ejected from the discharge end of the feed pipe 304 at a high flow rate. It is splashed open by the rotating material dispersing component 306 and fully contacts the hot air in the dehydration cylinder 301 to evaporate the moisture on the surface of the titanium return material. The titanium return material ejected at a high flow rate impacts the inclined plate 3067, thereby driving the rotating material dispersing component 306 and the hanging rod 319 to rotate together. The rotation of the rotating material dispersing component 306 generates centrifugal force, and the titanium return material falling into the centrifugal dispersion hood 3065 is thrown off the water adhering to the surface of the titanium return material under the action of centrifugal force. Then the titanium return material is thrown out of the centrifugal dispersion hood 3065 again, which enhances the separation effect of the titanium return material from the water adhering to its surface.

[0052] After centrifugation and dehydration in the centrifugal dispersion hood 3065, the titanium return material is thrown out of the centrifugal dispersion hood 3065 and falls onto the annular heat conduction groove 307. The hot air input into the annular heat conduction groove 307 blows the titanium return material that has fallen onto its surface again through the vent holes, and blows the titanium return material to dehydrate it again, so as to ensure the dehydration effect of the titanium return material, which facilitates the subsequent drying process of the titanium return material, improves the drying efficiency, and thus reduces the drying energy consumption.

[0053] Example 2:

[0054] Based on Specific Embodiment 1, the difference in this embodiment is as follows:

[0055] like Figure 5-8 As shown, an air guide pipe 311 runs through the bottom of the dehydration cylinder 301, and an annular air supply pipe 312 is connected to the input end of the air guide pipe 311. The air guide pipe 311 is arranged in an annular pattern at equal intervals on the conical surface at the bottom of the dehydration cylinder 301.

[0056] An annular air guide sleeve 313, which communicates with an annular heat conduction groove 307, is fitted onto the dewatering cylinder 301. An air supply pipe 314, which communicates with the inner cavity of the annular air guide sleeve 313, passes through the annular air guide sleeve 313. A limiting flange 315 for installing the annular air guide sleeve 313 is provided on the dewatering cylinder 301. The annular heat conduction groove 307 blocks the titanium return material that is centrifugally ejected, slows down its falling speed, increases its contact area with hot air, and further improves the dewatering effect on the titanium return material.

[0057] The annular air supply pipe 312 blows sufficient hot air into the bottom of the dehydration cylinder 301 through the air guide pipe 311. The hot air rises through the material guide port formed inside the dehydration cylinder 301 by the annular heat conduction groove 307. With the help of the air extraction pipe on the cylinder cover 302, the airflow for dehydration flows in the set direction, so that the water vapor generated during the dehydration process can flow out of the dehydration cylinder 301 with the airflow, thereby ensuring the dehydration effect on the titanium return material.

[0058] Example 3:

[0059] Based on specific embodiment two, the difference in this embodiment is as follows:

[0060] like Figure 3 , 4As shown in Figures 13 and 14, the return material lifting structure 4 includes a guide pipe 401. A connecting pipe 402 that communicates with the inner cavity of the guide pipe 401 is fixed on the guide pipe 401. One end of the connecting pipe 402 away from the guide pipe 401 is connected to the discharge pipe 310. An installation sleeve 403 is fitted on the guide pipe 401. The installation sleeve 403 is fixed to the inner wall of the box 1 by bolts. A rotating shaft 404 runs through the inner axis of the guide tube 401. A servo motor 405 with an output shaft fixed to one end of the guide tube 401 and fixedly connected to the rotating shaft 404 is fixed. A spiral fan blade 406 is fixed on the outer circular surface of one end of the rotating shaft 404 inside the guide tube 401. A feeding bend 407 communicating with the inner cavity of the guide tube 401 is fixed at the top of the guide tube 401. A telescopic pipe 408 extending to the feed end of the tunnel dryer 5 is fixed at the discharge end of the feeding bend 407. The bottom discharge end of the telescopic pipe 408 is close to the feed end of the tunnel dryer 5. During the feeding process, the returned material can be concentrated at the feed end, avoiding the return material from splashing everywhere due to the high height difference.

[0061] The servo motor 405 drives the rotating shaft 404 to rotate, which causes the spiral fan blade 406 to carry the return material that has entered the guide pipe 401 to rise. The return material that rises under the drive of the spiral fan blade 406 enters the discharge bend 407 and finally enters the telescopic pipe 408, from which it is transferred to the tunnel drying oven 5 for drying.

[0062] Inside the housing 1 and below the discharge end of the tunnel drying oven 5, there is a discharge chute 6. The discharge end of the discharge chute 6 passes through the housing 1 and extends to the outside of the housing 1. The discharge chute 6 is used to receive the return material after it has been dried by the tunnel drying oven 5 and to transfer it to the next return material processing step through the discharge port.

[0063] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
