Description

Technical Field

[0001] The present invention relates to the technical field of cobalt-chromium alloy powder storage equipment, and in particular to a cobalt-chromium alloy powder storage device for 3D printing and a method for using the same. Background Art

[0002] 3D printing is a type of rapid prototyping technology. It is a technology that uses digital model files as the basis and uses powdered metal or plastic and other bondable materials to construct objects by printing layer by layer. 3D printing is usually achieved using digital technology material printers. It is often used to make models in the fields of mold manufacturing, industrial design, etc., and is gradually used for the direct manufacturing of some products. In the process of 3D printing, cobalt-chromium alloy powder is often used for printing, and a large amount of cobalt-chromium alloy powder will be used in the process of 3D printing, so the storage of cobalt-chromium alloy powder is more critical.

[0003] When storing cobalt-chromium alloy powder, due to the high density of cobalt-chromium alloy powder, when there is a large amount of cobalt-chromium alloy powder stored in the storage device, the cobalt-chromium alloy powder at the bottom will be subjected to greater pressure. If it is stored for a long time, the cobalt-chromium alloy powder at the bottom will form some small lumps due to excessive pressure, or stick to the bottom plate, causing inconvenience in later use and trouble in cleaning. In view of the above problems, the following solutions are proposed. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a cobalt-chromium alloy powder storage device for 3D printing, comprising a storage tank, a fixed shell is fixedly connected to the outer wall of the storage tank, an auger is rotatably connected to the inner wall of the fixed shell, an arc bottom plate is fixedly connected to the inner wall of the storage tank, a dehumidification component is fixedly connected to the inner wall of the storage tank, and an anti-blocking component is fixedly connected to the outer wall of the auger; The power mechanism includes a fixed bracket 1 fixedly connected to the top of the storage tank, a motor is fixedly connected to the top of the fixed bracket 1, a bevel gear 1 is fixedly connected to the outer wall of the motor, a bevel gear 2 is fixedly connected to the top of the auger, the outer wall of the bevel gear 1 is meshed with the outer wall of the bevel gear 2, a feed trough is provided on the inner wall of the storage tank, and a discharge trough is provided on the inner wall of the storage tank; The outer shell mechanism includes a protective cover fixedly connected to the top of the storage tank, a discharge port fixedly connected to the inner wall of the fixed shell, a feed port fixedly connected to the inner wall of the storage tank, and a heat dissipation hole opened on the inner wall of the protective cover. The cobalt-chromium alloy powder will slide down to the feed trough along the arc-shaped bottom plate after being loaded into the storage tank, and an auger is set. After the cobalt-chromium alloy powder is filled, the discharge port and the feed port are blocked with a sealing plug, and the motor is started at the same time to be powered on. When the motor is powered on, it drives the bevel gear 1 to rotate. When the bevel gear 1 rotates, the auger is driven to rotate through the bevel gear 2. Due to the design of the arc-shaped inclined surface of the arc-shaped bottom plate, the cobalt-chromium alloy stored at the bottom of the storage tank The powder will slide along the curved bottom plate to the feed chute and fall to the bottom of the auger. When the auger rotates, it is driven up and then slides from the discharge chute to the top of the cobalt-chromium alloy powder. In this way, the cobalt-chromium alloy powder at the bottom is lifted to the top to avoid the cobalt-chromium alloy powder at the bottom being subjected to greater pressure during long-term storage due to the large amount of cobalt-chromium alloy powder in the storage tank and the high density of the cobalt-chromium alloy powder. This will cause some small agglomerates to form, which will affect the use of the cobalt-chromium alloy powder in the later stage. In addition, under the rotation of the auger, the cobalt-chromium alloy powder in the storage tank will not stay on the inner wall and the curved bottom plate of the storage tank for a long time, reducing the possibility of the cobalt-chromium alloy powder sticking to the inside of the storage tank, which is convenient for the later discharge and cleaning.

[0005] Preferably, the anti-blocking component includes a conical protrusion fixedly connected to the outer wall of the auger, a hydraulic box fixedly connected to the inner wall of the storage tank, a sliding rod slidably connected to the inner wall of the hydraulic box, a piston plate fixedly connected to the outer wall of the sliding rod, the outer wall of the piston plate is slidably connected to the inner wall of the hydraulic box, and a telescopic spring is fixedly connected to the outer wall of the piston plate. Since the conical protrusion is fixed on the auger, when the auger rotates, the conical protrusion is synchronously driven to rotate. When the conical protrusion rotates, it contacts the sliding rod and squeezes the sliding rod to contract. When the sliding rod contracts, the hydraulic oil that flows out will flow back to the hydraulic box through the piston plate.

[0006] Preferably, the anti-blocking component also includes a hydraulic pipe fixedly connected to the inner wall of the hydraulic box, a fixed bracket 2 is fixedly connected to the inner wall of the fixed shell, a telescopic rod is fixedly connected to the outer wall of the fixed bracket 2, the inner wall of the telescopic rod is fixedly connected to the outer wall of the hydraulic pipe, a pushing plate is fixedly connected to the outer wall of the telescopic rod, and a sliding plate is slidably connected to the inner wall of the pushing plate. Utilizing the characteristic that the conical protrusion indirectly contacts the sliding rod when the auger rotates, a hydraulic box is provided. When the sliding rod does not contact the conical protrusion, the piston plate is pushed to the left by the telescopic spring, driving the hydraulic oil to enter the telescopic rod and the pushing plate through the hydraulic pipe, so that the pushing plate The movable plate and the sliding plate extend outward, and when the sliding rod contacts the conical protrusion, the sliding rod is squeezed to move to the right. At this time, negative pressure will be generated in the hydraulic box to cause the hydraulic oil to flow back. When the hydraulic oil flows back, it drives the telescopic rod and the sliding plate to retract, and so on. When the auger is continuously rotating, the telescopic rod will continuously expand and contract, and drive the pushing plate and the sliding plate to push the cobalt-chromium alloy powder accumulated at the discharge chute, so as to avoid the cobalt-chromium alloy powder accumulating at the discharge chute, which will hinder the discharge of the cobalt-chromium alloy powder and then form an accumulation on the top of the auger, which will hinder the operation of the auger, and the cobalt-chromium alloy powder will also be gradually squeezed to form small lumps, affecting subsequent use.

[0007] Preferably, the anti-blocking component also includes a fixed column 1 fixedly connected to the inner wall of the telescopic rod, a spring sheet is fixedly connected to the outer wall of the fixed column 1, a buckle is fixedly connected to the inner wall of the spring sheet, the outer wall of the buckle is slidably connected to the inner wall of the telescopic rod, a clamping groove 1 is provided on the inner wall of the telescopic rod, and a clamping groove 2 is provided on the inner wall of the telescopic rod. By utilizing the above-mentioned characteristics of the telescopic rod extending back and forth, a spring sheet is provided. When hydraulic oil enters the telescopic rod, the buckle inside the telescopic rod is stuck in the clamping groove 2 under the action of the spring sheet. The hydraulic oil will continue to enter the inside of the push plate and then push the sliding plate to extend outward until the sliding plate is fully extended. The continued influx of hydraulic oil will push the telescopic rod to extend outward until the buckle is stuck in the clamping groove 1. When the hydraulic oil flows back to the hydraulic tank, The buckle is stuck on the first slot, so that when the hydraulic oil flows back, it will first drive the sliding plate to contract, and then drive the telescopic rod to retract until the buckle is stuck on the second slot. Through the operation of the above-mentioned components, the telescopic rod will first extend the sliding plate outward before extending outward, thereby increasing the contact area between the pushing plate and the cobalt-chromium alloy powder, and then when the cobalt-chromium alloy powder is pushed outward to pile up, more cobalt-chromium alloy powder can be pushed. When the telescopic rod retracts, the sliding plate is also retracted first, and then the telescopic rod is retracted, so as to avoid the situation where the sliding plate brings some cobalt-chromium alloy powder accumulated at the discharge chute back to the discharge chute when the telescopic rod retracts first or retracts midway, causing the discharge chute to be blocked, or the telescopic rod cannot be retracted to the position where the buckle is stuck in the second slot, causing changes in the operation of the telescopic rod, thereby affecting the operation of the entire equipment.

[0008] Preferably, the dehumidification component includes a fixed bracket three fixedly connected to the inner wall of the storage tank, an air pressure box is fixedly connected to the outer wall of the fixed bracket three, a piston rod is slidably connected to the inner wall of the air pressure box, the outer wall of the piston rod is fixedly connected to the outer wall of the push plate, a telescopic spring two is fixedly connected to the outer wall of the piston rod, and an air intake pipe is fixedly connected to the inner wall of the air pressure box. When the telescopic rod is extended and retracted, the piston rod can be moved synchronously through the push plate. When the piston rod moves to the right, negative pressure is generated inside the air pressure box, so that the gas in the storage tank can enter the air pressure box through the air intake pipe, and then when the piston rod moves to the left, the incoming gas will be transported to the other end.

[0009] Preferably, the dehumidification component also includes a one-way valve 1 rotatably connected to the inner wall of the air inlet pipe, a connecting pipe is fixedly connected to the inner wall of the air pressure box, a one-way valve 2 is rotatably connected to the inner wall of the connecting pipe, a cooling box is fixedly connected to the outer wall of the connecting pipe, a fixing column 2 is fixedly connected to the top of the cooling box, and the top of the fixing column 2 is fixedly connected to the inner wall of the storage tank. Through the extrusion of the piston rod, the gas in the air pressure box will pass through the one-way valve 2 and enter the connecting pipe. During continuous pushing, the gas in the connecting pipe will enter the interior of the cooling box, and then the gas will be condensed in the cooling box to discharge the moisture in the gas.

[0010] Preferably, the dehumidification component also includes a metal partition fixedly connected to the inner wall of the cooling box, a water storage tank is provided on the inner wall of the cooling box, an air outlet is provided on the inner wall of the cooling box, a water outlet pipe is fixedly connected to the inner wall of the cooling box, the outer wall of the water outlet pipe is fixedly connected to the inner wall of the storage tank, and a spring partition is slidably connected to the inner wall of the cooling box. By utilizing the characteristic that the telescopic rod drives the pushing plate to move when it is extended and retracted, an air pressure box is provided. When the telescopic rod is extended and retracted, the piston rod is driven to move synchronously through the pushing plate. When the piston rod moves to the right, negative pressure is generated in the air pressure box, so that the gas in the storage tank can enter the air pressure box from the air inlet pipe through the one-way valve 1, and then when the piston rod moves to the left, the gas in the air pressure box is squeezed, so that it passes through the one-way valve 2 and enters the connecting pipe, and then reaches the inside of the cooling box. Due to the characteristics of the conical convex block, when the piston rod moves to the left under the action of the telescopic spring 2, the pushing speed is faster, so that the gas entering the cooling box will also be discharged at a faster speed. The gas goes out from the outlet at a high speed, and when the gas goes out, due to the characteristics of the conical surface of the metal partition, when the gas contacts and rises, it will become smaller and smaller with the upper end, and the gas flow rate will increase, so that the gas changes from the low pressure at the bottom to the high pressure at the top, so that some water vapor in the gas will adhere to the metal partition. In addition, the coolant is stored in the water tank. Since the metal partition is made of metal, the temperature transfer is faster. When the water vapor in the gas encounters the colder metal partition, it will also be condensed into small water droplets when it encounters the colder metal partition and adhere to the metal partition. Finally, the small water droplets gather together and slide down onto the spring partition. When more water gathers, its weight will press the spring partition down, and then the water can be discharged out through the water outlet pipe. Through the operation of the above components, some of the humid gas in the storage tank can be removed, so that the storage tank can be kept in a relatively dry environment, and the humid gas in the storage tank can be avoided, so that the cobalt-chromium alloy powder can be prevented from getting damp, and then some lumps can be formed, affecting subsequent use.

[0011] A method for using a cobalt-chromium alloy powder storage device for 3D printing comprises the following steps: S1: filling; S2: Power on and run; S3: Conveying up.

[0012] The present invention has the following beneficial effects: (1) The present invention utilizes the characteristic that after the cobalt-chromium alloy powder is loaded into the storage tank, it will slide down to the feed trough along the arc-shaped bottom plate, and sets an auger. After the cobalt-chromium alloy powder is filled, the discharge port and the feed port are blocked with a sealing plug, and the motor is started and powered on. When the motor is powered on, it drives the bevel gear 1 to rotate. When the bevel gear 1 rotates, the auger is driven to rotate through the bevel gear 2. Due to the design of the arc-shaped inclined surface of the arc-shaped bottom plate, the cobalt-chromium alloy powder stored at the bottom of the storage tank will slide down to the feed trough along the arc-shaped bottom plate and fall to the bottom of the auger. When the auger rotates, it is The auger drives the powder upward and then slides down from the discharge chute to the top of the cobalt-chromium alloy powder, thereby lifting the cobalt-chromium alloy powder at the bottom to the top to avoid the formation of some small agglomerates due to the large amount of cobalt-chromium alloy powder in the storage tank and the high density of the cobalt-chromium alloy powder during long-term storage, which will affect the use of the cobalt-chromium alloy powder in the later stage. In addition, under the rotation of the auger, the cobalt-chromium alloy powder in the storage tank will not stay on the inner wall and the curved bottom plate of the storage tank for a long time, reducing the possibility of the cobalt-chromium alloy powder sticking to the inside of the storage tank and facilitating the later discharge and cleaning.

[0013] When the auger is in contact with the conical protrusion, the piston plate is pushed to the left by the telescopic spring, driving the hydraulic oil to enter the telescopic rod and the push plate through the hydraulic pipe, so that the push plate and the sliding plate extend outward. When the sliding rod contacts the conical protrusion, it squeezes the sliding rod to move to the right. At this time, negative pressure is generated in the hydraulic box, causing the hydraulic oil to flow back. When the hydraulic oil flows back, the telescopic rod and the sliding plate are driven to retract, and this cycle is repeated. When the auger is continuously rotating, the telescopic rod is continuously extended and retracted, driving the push plate and the sliding plate to push the cobalt-chromium alloy powder accumulated at the discharge trough, so as to avoid the cobalt-chromium alloy powder accumulating at the discharge trough, which hinders the discharge of the cobalt-chromium alloy powder and forms an accumulation at the top of the auger, which hinders the operation of the auger. In addition, the cobalt-chromium alloy powder is gradually squeezed to form small lumps, which affect subsequent use.

[0014] (3) The present invention utilizes the above-mentioned characteristic of the telescopic rod to extend and retract back and forth, and sets a spring sheet. When the hydraulic oil enters the telescopic rod, the buckle inside the telescopic rod is stuck in the second clamping groove under the action of the spring sheet. The hydraulic oil will continue to enter the inside of the push plate, and then push the sliding plate to extend outward until the sliding plate is fully extended. The continued influx of hydraulic oil will push the telescopic rod to extend outward until the buckle is stuck on the first clamping groove. When the hydraulic oil flows back to the hydraulic box, the buckle is stuck on the first clamping groove, so that when the hydraulic oil flows back, it will first drive the sliding plate to shrink, and then drive the telescopic rod to retract until the buckle is stuck on the second clamping groove. Through the operation of the above components, the telescopic rod will first extend the sliding plate outward before extending outward, thereby increasing the contact area between the pushing plate and the cobalt-chromium alloy powder. Then, when the cobalt-chromium alloy powder is pushed outward to pile up, more cobalt-chromium alloy powder can be pushed. When the telescopic rod retracts, the sliding plate is also retracted first, and then the telescopic rod is retracted, so as to avoid the situation where the sliding plate brings some cobalt-chromium alloy powder accumulated at the discharge chute back to the discharge chute when the telescopic rod retracts first or retracts midway, causing the discharge chute to be blocked, or the telescopic rod cannot be retracted to the position where the buckle is stuck in the second card slot, causing changes in the operation of the telescopic rod, thereby affecting the operation of the entire equipment.

[0015] (4) The present invention utilizes the characteristic that the telescopic rod drives the push plate to move when it is extended and retracted, and sets an air pressure box. When the telescopic rod is extended and retracted, the piston rod is driven to move synchronously through the push plate. When the piston rod moves to the right, negative pressure is generated in the air pressure box, so that the gas in the storage tank can enter the air pressure box from the air inlet pipe through the one-way valve 1. Then, when the piston rod moves to the left, the gas in the air pressure box is squeezed, so that it enters the connecting pipe through the one-way valve 2 and then reaches the inside of the cooling box. Due to the characteristics of the conical protrusion, when the piston rod moves to the left under the action of the telescopic spring 2, the pushing speed is faster, so that the gas entering the cooling box will also go out from the air outlet at a faster speed. When the gas goes out, due to the characteristics of the conical surface of the metal partition, when the gas contacts and rises, it will become smaller and smaller with the upper end. The gas flow rate will be accelerated, causing the gas to change from the low pressure at the bottom to the high pressure at the top, causing some water vapor in the gas to adhere to the metal partition. In addition, the water tank stores coolant. Since the metal partition is made of metal, the temperature transfer is faster. When the water vapor in the gas encounters the colder metal partition, it will also condense into small water droplets and adhere to the metal partition. Finally, the small water droplets gather together and slide down onto the spring partition. When more water gathers, its weight will press the spring partition down, and then the water can be discharged outward through the outlet pipe. Through the operation of the above components, some of the humid gas in the storage tank can be removed, so that the storage tank can be kept in a relatively dry environment, and the humid gas in the storage tank can be prevented from making the cobalt-chromium alloy powder damp, and then forming some lumps, affecting subsequent use.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] For example, see Figure 1 - Figure 3 The present invention is a cobalt-chromium alloy powder storage device for 3D printing, comprising a storage tank 1, a fixed shell 101 is fixedly connected to the outer wall of the storage tank 1, an auger 102 is rotatably connected to the inner wall of the fixed shell 101, an arc bottom plate 103 is fixedly connected to the inner wall of the storage tank 1, a dehumidification component 5 is fixedly connected to the inner wall of the storage tank 1, and an anti-blocking component 4 is fixedly connected to the outer wall of the auger 102; The power mechanism 2 includes a fixed bracket 201 fixedly connected to the top of the storage tank 1, a motor 202 is fixedly connected to the top of the fixed bracket 201, a bevel gear 203 is fixedly connected to the outer wall of the motor 202, a bevel gear 204 is fixedly connected to the top of the auger 102, the outer wall of the bevel gear 203 is meshed with the outer wall of the bevel gear 204, a feed trough 205 is provided on the inner wall of the storage tank 1, and a discharge trough 206 is provided on the inner wall of the storage tank 1; The outer shell mechanism 3 includes a protective cover 301 fixedly connected to the top of the storage tank 1, a discharge port 302 is fixedly connected to the inner wall of the fixed shell 101, and a feed port 303 is fixedly connected to the inner wall of the storage tank 1. A heat dissipation hole 304 is opened on the inner wall of the protective cover 301. A screw dragon 102 is provided by utilizing the characteristic that the cobalt-chromium alloy powder will slide down to the feed trough 205 along the arc-shaped bottom plate 103 after being loaded into the storage tank 1. After the cobalt-chromium alloy powder is filled, the discharge port 302 and the feed port 303 are blocked with a sealing plug, and the motor 202 is started at the same time to be powered on. When the motor 202 is powered on, it drives the bevel gear 1 203 to rotate. When the bevel gear 1 203 rotates, the bevel gear 2 204 drives the screw dragon 102 to rotate. Due to the arc-shaped inclined surface of the arc-shaped bottom plate 103 According to the design, the cobalt-chromium alloy powder stored at the bottom of the storage tank 1 will slide along the curved bottom plate 103 to the feed trough 205 and fall to the bottom of the auger 102. When the auger 102 rotates, it is driven to rise and then slide from the discharge trough 206 to the top of the cobalt-chromium alloy powder. In this way, the cobalt-chromium alloy powder at the bottom is lifted to the top, avoiding the formation of some small agglomerates due to the large amount of cobalt-chromium alloy powder in the storage tank 1 and the high density of the cobalt-chromium alloy powder during long-term storage, thereby affecting the use of the cobalt-chromium alloy powder in the later stage. In addition, under the rotation of the auger 102, the cobalt-chromium alloy powder in the storage tank 1 will not stay on the inner wall of the storage tank 1 and the curved bottom plate 103 for a long time, reducing the possibility of the cobalt-chromium alloy powder sticking to the inside of the storage tank 1, and facilitating the later discharge and cleaning.

[0021] For example 2, please refer to Figure 4 - Fig.10 The present invention is a cobalt-chromium alloy powder storage device for 3D printing. On the basis of the first embodiment, the anti-blocking component 4 includes a conical protrusion 401 fixedly connected to the outer wall of the auger 102, a hydraulic box 402 is fixedly connected to the inner wall of the storage tank 1, a sliding rod 403 is slidably connected to the inner wall of the hydraulic box 402, a piston plate 404 is fixedly connected to the outer wall of the sliding rod 403, the outer wall of the piston plate 404 is slidably connected to the inner wall of the hydraulic box 402, and a telescopic spring 405 is fixedly connected to the outer wall of the piston plate 404. Since the conical protrusion 401 is fixed on the auger 102, when the auger 102 rotates, the conical protrusion 401 is synchronously driven to rotate. When the conical protrusion 401 rotates, it contacts the sliding rod 403 and squeezes the sliding rod 403 to contract. When the sliding rod 403 contracts, the hydraulic oil flowing out will flow back to the hydraulic box 402 through the piston plate 404.

[0022] The anti-blocking component 4 also includes a hydraulic pipe 406 fixedly connected to the inner wall of the hydraulic box 402, a fixed bracket 407 is fixedly connected to the inner wall of the fixed shell 101, a telescopic rod 408 is fixedly connected to the outer wall of the fixed bracket 407, the inner wall of the telescopic rod 408 is fixedly connected to the outer wall of the hydraulic pipe 406, a push plate 409 is fixedly connected to the outer wall of the telescopic rod 408, and a sliding plate 410 is slidably connected to the inner wall of the push plate 409. When the auger 102 rotates, the conical protrusion 401 indirectly contacts the sliding rod 403, and a hydraulic box 402 is set. When the sliding rod 403 does not contact the conical protrusion 401, the piston plate 404 is pushed to the left by the telescopic spring 405, driving the hydraulic oil to enter the telescopic rod 408 and the push plate 410 through the hydraulic pipe 406. In the movable plate 409, the push plate 409 and the sliding plate 410 are extended outward. When the sliding rod 403 contacts the conical protrusion 401, the sliding rod 403 is squeezed to move to the right. At this time, negative pressure will be generated in the hydraulic box 402, causing the hydraulic oil to flow back. When the hydraulic oil flows back, the telescopic rod 408 and the sliding plate 410 are driven to retract, and this reciprocating process is realized. When the auger 102 is continuously rotating, the telescopic rod 408 will continuously expand and contract, and drive the push plate 409 and the sliding plate 410 to push the cobalt-chromium alloy powder accumulated at the discharge trough 206, so as to avoid the cobalt-chromium alloy powder from accumulating at the discharge trough 206, which will hinder the discharge of the cobalt-chromium alloy powder and then form an accumulation on the top of the auger 102, which will hinder the operation of the auger 102, and the cobalt-chromium alloy powder will also be gradually squeezed to form small lumps, affecting subsequent use.

[0023] The anti-blocking component 4 also includes a fixing column 1 411 fixedly connected to the inner wall of the telescopic rod 408, a spring sheet 412 is fixedly connected to the outer wall of the fixing column 1 411, a buckle 413 is fixedly connected to the inner wall of the spring sheet 412, the outer wall of the buckle 413 is slidably connected to the inner wall of the telescopic rod 408, a card slot 1 414 is opened on the inner wall of the telescopic rod 408, and a card slot 2 415 is opened on the inner wall of the telescopic rod 408. By utilizing the above-mentioned telescopic rod 408's telescopic characteristics, a setting A spring sheet 412, when the hydraulic oil enters the telescopic rod 408, at this time, due to the buckle 413 inside the telescopic rod 408, under the action of the spring sheet 412, it is stuck in the second card slot 415, and the hydraulic oil will continue to enter the inside of the push plate 409, and then push the sliding plate 410 to extend outward until the sliding plate 410 is fully extended. The continued influx of hydraulic oil will push the telescopic rod 408 to extend outward until the buckle 413 is stuck on the card slot 1 414, and the hydraulic oil will flow back to the hydraulic box 4 02, at this time, the buckle 413 is stuck on the card slot 1 414, so that when the hydraulic oil flows back, it will first drive the sliding plate 410 to shrink, and then drive the telescopic rod 408 to retract, until the buckle 413 is stuck on the card slot 2 415. Through the operation of the above components, the telescopic rod 408 will first extend the sliding plate 410 outward before extending outward, increasing the contact area between the push plate 409 and the cobalt-chromium alloy powder, and then when the cobalt-chromium alloy powder is pushed outward to pile up, more cobalt-chromium alloy powder can be pushed. When the telescopic rod 408 retracts, the sliding plate 410 is also retracted first, and then the telescopic rod 408 is retracted, to prevent the sliding plate 410 from bringing some cobalt-chromium alloy powder accumulated again at the discharge chute 206 back to the discharge chute 206 when the telescopic rod 408 retracts first or retracts midway, causing the discharge chute 206 to be blocked, or the telescopic rod 408 cannot be retracted to the position where the buckle 413 is stuck in the second slot 415, causing changes in the operation of the telescopic rod 408, thereby affecting the operation of the entire equipment.

[0024] The dehumidification component 5 includes a fixed bracket 3 501 fixedly connected to the inner wall of the storage tank 1, an air pressure box 502 is fixedly connected to the outer wall of the fixed bracket 3 501, a piston rod 503 is slidably connected to the inner wall of the air pressure box 502, the outer wall of the piston rod 503 is fixedly connected to the outer wall of the push plate 409, a telescopic spring 2 504 is fixedly connected to the outer wall of the piston rod 503, and an air intake pipe 505 is fixedly connected to the inner wall of the air pressure box 502. When the telescopic rod 408 is extended and retracted, the piston rod 503 can be moved synchronously through the push plate 409. When the piston rod 503 moves to the right, negative pressure is generated inside the air pressure box 502, so that the gas in the storage tank 1 can enter the air pressure box 502 through the air intake pipe 505, and then when the piston rod 503 moves to the left, the incoming gas will be transported to the other end.

[0025] The dehumidification component 5 also includes a one-way valve 506 rotatably connected to the inner wall of the air inlet pipe 505, a connecting pipe 507 is fixedly connected to the inner wall of the air pressure box 502, a one-way valve 508 is rotatably connected to the inner wall of the connecting pipe 507, a cooling box 509 is fixedly connected to the outer wall of the connecting pipe 507, a fixing column 510 is fixedly connected to the top of the cooling box 509, and the top of the fixing column 510 is fixedly connected to the inner wall of the storage tank 1. Through the squeezing of the piston rod 503, the gas in the air pressure box 502 will pass through the one-way valve 508 and enter the connecting pipe 507. During the continuous pushing, the gas in the connecting pipe 507 will enter the interior of the cooling box 509, and then the gas will be condensed in the cooling box 509 to discharge the moisture in the gas.

[0026] The dehumidification component 5 also includes a metal partition 511 fixedly connected to the inner wall of the cooling box 509, a water storage tank 512 is provided on the inner wall of the cooling box 509, an air outlet 513 is provided on the inner wall of the cooling box 509, a water outlet pipe 514 is fixedly connected to the inner wall of the cooling box 509, the outer wall of the water outlet pipe 514 is fixedly connected to the inner wall of the storage tank 1, and a spring partition 515 is slidably connected to the inner wall of the cooling box 509. The characteristic that the telescopic rod 408 drives the push plate 409 to move when the telescopic rod 408 is extended and retracted is utilized to set an air pressure box 502. When the piston rod 503 moves to the right, the piston rod 503 is driven to move synchronously by the push plate 409. When the piston rod 503 moves to the right, negative pressure is generated in the air pressure box 502, so that the gas in the storage tank 1 can enter the air pressure box 502 from the air inlet pipe 505 through the one-way valve 1 506. Then, when the piston rod 503 moves to the left, the gas in the air pressure box 502 is squeezed, so that the gas passes through the one-way valve 2 508 and enters the connecting pipe 507, and then reaches the inside of the cooling box 509. Due to the characteristics of the conical protrusion 401, when the piston rod 503 moves to the left under the action of the telescopic spring 2 504, the , pushing at a faster speed, so that the gas entering the cooling box 509 will also go out from the gas outlet 513 at a faster speed. When the gas goes out, due to the characteristics of the conical surface of the metal partition 511, when the gas contacts and rises, it will become smaller and smaller with the upper end, and the gas flow rate will be accelerated, so that the gas changes from the low pressure at the bottom to the high pressure at the top, so that some water vapor in the gas will adhere to the metal partition 511. In addition, the water tank 512 stores coolant. Since the metal partition 511 is made of metal, the temperature transfer is faster. When the water vapor in the gas meets When it reaches the colder metal partition 511, it will also be cooled and condensed into small water droplets that adhere to the metal partition 511. Finally, the small water droplets gather together and slide down to the spring partition 515. When a lot of water gathers, its weight will press the spring partition 515 to move down, and then the water can be discharged outward through the outlet pipe 514. Through the operation of the above components, part of the humid gas in the storage tank 1 can be removed, so that the storage tank 1 maintains a relatively dry environment, and the humid gas in the storage tank 1 can be prevented from making the cobalt-chromium alloy powder damp, and then forming some lumps, affecting subsequent use.

[0027] The method for using the cobalt-chromium alloy powder storage device comprises the following steps: S1: filling; S2: Power on and run; S3: Conveying up.

[0028] A specific application of this embodiment is: before using the device, first install the device at the required position, put the cobalt-chromium alloy powder to be stored into the storage tank 1, then block the discharge port 302 and the feed port 303 with sealing plugs, and turn on the power of the motor 202 to allow it to operate. When the motor 202 is powered on, it drives the bevel gear 1 203 to rotate. When the bevel gear 1 203 rotates, the bevel gear 2 204 drives the auger 102 to rotate. Due to the design of the arc-shaped inclined surface of the arc-shaped bottom plate 103, the cobalt-chromium alloy powder stored at the bottom of the storage tank 1 will slide along the arc-shaped bottom plate 103 to the feed trough 205 and fall to the bottom of the auger 102. When the auger 102 rotates, it is driven to rise and then slides from the discharge chute 206 to the top of the cobalt-chromium alloy powder, thereby lifting the cobalt-chromium alloy powder at the bottom to the top, avoiding the cobalt-chromium alloy powder at the bottom being subjected to greater pressure during long-term storage due to the large amount of cobalt-chromium alloy powder in the storage tank 1 and the high density of the cobalt-chromium alloy powder, which will form some small lumps and affect the use of the cobalt-chromium alloy powder in the later stage. In addition, under the rotation of the auger 102, the cobalt-chromium alloy powder in the storage tank 1 will not stay on the inner wall of the storage tank 1 and the curved bottom plate 103 for a long time, reducing the possibility of the cobalt-chromium alloy powder sticking to the inside of the storage tank 1, which is convenient for the later discharge and cleaning.

[0029] Taking advantage of the fact that the conical protrusion 401 will indirectly contact the sliding rod 403 when the auger 102 rotates, a hydraulic box 402 is set. When the sliding rod 403 is not in contact with the conical protrusion 401, the piston plate 404 is pushed to the left by the telescopic spring 405, driving the hydraulic oil to enter the telescopic rod 408 and the push plate 409 through the hydraulic pipe 406, so that the push plate 409 and the sliding plate 410 extend outward. When the sliding rod 403 contacts the conical protrusion 401, the sliding rod 403 will be squeezed to move to the right. At this time, negative pressure will be generated in the hydraulic box 402, causing the hydraulic oil to flow back. When the hydraulic oil flows back, the telescopic rod 408 and the sliding plate 4 10 is retracted, and so on, so that when the auger 102 is continuously rotating, the telescopic rod 408 will be continuously extended and retracted, and drive the pushing plate 409 and the sliding plate 410 to push the cobalt-chromium alloy powder accumulated at the discharge trough 206, so as to prevent the cobalt-chromium alloy powder from accumulating at the discharge trough 206, so that the cobalt-chromium alloy powder is blocked when discharging, and then accumulates on the top of the auger 102, so that the operation of the auger 102 is blocked, and the cobalt-chromium alloy powder will also be gradually squeezed to form small agglomerates, affecting subsequent use. When the hydraulic oil enters the telescopic rod 408, at this time, due to the buckle 413 in the telescopic rod 408, under the action of the spring sheet 412, it is stuck in the card slot 4 15, the hydraulic oil will continue to enter the inside of the push plate 409, and then push the sliding plate 410 to extend outward until the sliding plate 410 is fully extended. The continued influx of hydraulic oil will push the telescopic rod 408 to extend outward until the buckle 413 is stuck on the card slot 1 414. When the hydraulic oil flows back to the hydraulic box 402, the buckle 413 is stuck on the card slot 1 414, so that when the hydraulic oil flows back, it will first drive the sliding plate 410 to contract, and then drive the telescopic rod 408 to retract until the buckle 413 is stuck on the card slot 2 415. Through the operation of the above components, the telescopic rod 408 will first extend the sliding plate 410 outward before extending outward. When the telescopic rod 408 is retracted, the sliding plate 410 is also retracted first, and then the telescopic rod 408 is retracted to prevent the sliding plate 410 from bringing some cobalt-chromium alloy powder that has been accumulated again at the discharge chute 206 back to the discharge chute 206 when the telescopic rod 408 is retracted first or halfway, thereby clogging the discharge chute 206 or preventing the telescopic rod 408 from retracting to the position where the buckle 413 is stuck in the second slot 415, causing changes in the operation of the telescopic rod 408, thereby affecting the operation of the entire equipment.

[0030] By utilizing the characteristic that the telescopic rod 408 drives the push plate 409 to move when it is extended or retracted, an air pressure box 502 is provided. When the telescopic rod 408 is extended or retracted, the piston rod 503 is driven to move synchronously through the push plate 409. When the piston rod 503 moves to the right, negative pressure is generated in the air pressure box 502, so that the gas in the storage tank 1 can enter the air pressure box 502 from the air inlet pipe 505 through the one-way valve 1 506. Then, when the piston rod 503 moves to the left, the gas in the air pressure box 502 is squeezed, so that the gas passes through the one-way valve 2 508 and enters the connecting pipe 507, and then reaches the interior of the cooling box 509. Due to the characteristic of the conical protrusion 401, when the piston rod 503 moves to the left under the action of the telescopic spring 2 504, the pushing speed is faster, so that the gas entering the cooling box 509 will also go out from the air outlet 513 at a faster speed. When the gas goes out, due to the characteristic of the conical surface of the metal partition 511, the gas is When it rises in contact, it will become smaller and smaller as the upper end, and the gas flow rate will accelerate, causing the gas to change from the low pressure at the bottom to the high pressure at the top, so that some water vapor in the gas will adhere to the metal partition 511. In addition, the water tank 512 stores coolant. Since the metal partition 511 is made of metal, the temperature transfer is faster. When the water vapor in the gas encounters the colder metal partition 511, it will also condense into small water droplets when it encounters the colder metal partition 511 and adhere to the metal partition 511. Finally, the small water droplets gather together and slide down to the spring partition 515. When more water gathers, its weight will press the spring partition 515 downward, and then the water can be discharged outward through the water outlet pipe 514. Through the operation of the above components, some of the humid gas in the storage tank 1 can be removed, so that the storage tank 1 can maintain a relatively dry environment, and the humid gas in the storage tank 1 can be prevented from making the cobalt-chromium alloy powder damp, and then forming some lumps, affecting subsequent use.
