Description

Technical Field

[0001] The invention relates to the technical field of pressure supply tanks, and in particular to an argon pressurized refined powder supply tank and a powder distribution method thereof. Background Art

[0002] Refined powder supply tank usually refers to a device used to store and supply refined powder in the metal refining process, especially in the refining treatment of metal materials such as aluminum alloys. This equipment is generally called a refining powder spray tank. Its design and function are to optimize the refining process and improve the quality of metals. Refined powder supply tanks usually use pressure tanks. The pressure in the pressure tank is increased by pressurizing the pressure tank. The refined powder in the pressure tank is sprayed to the subsequent equipment through a pipeline through the positive pressure. The existing technology usually uses inert gas as the pressurized gas, and the more commonly used pressurized gas is argon.

[0003] However, the prior art has the following problems: 1. The discharge port of the existing argon pressurized refined powder supply tank is usually set at the bottom of the tank. After the supply tank is filled with refined powder, since there is more refined powder in the tank and the volume of the gas in the tank is small, the pressure will rise instantly after pressurization. As the refined powder is gradually discharged, the volume of the gas in the tank increases. Under the condition of maintaining the same argon delivery pressure, the pressure in the tank will gradually decrease, resulting in poor stability of the gas pressure in the tank, affecting the stability of the refined powder step.

[0004] 2. In the process of conveying the refined powder in the tank outward, the refined powder at the bottom of the tank is affected by the pressure of the upper refined powder and the argon pressure at the same time. When there is more refined powder in the tank, the amount of refined powder ejected is larger. As the refined powder in the tank gradually decreases, the amount of refined powder ejected also decreases. Under the same pressure, the amount of powder is larger at the beginning and then gradually decreases. As a result, the amount of refined powder is not stable enough, which is not convenient for the staff to control. Summary of the invention

[0022] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0023] Example 1: Please refer to Figure 1 - Figure 7, an argon pressurized refined powder supply tank, comprising: a tank body 1; a powder adding pipe 2 and an argon pipe 7 are installed on the top of the tank body 1, a discharging pipe 8 is installed on the side wall of the tank body 1, two hoppers 3 are connected to the top inner wall of the tank body 1, the powder adding pipe 2 is provided with two pipe openings, and the two pipe openings of the powder adding pipe 2 are respectively located above the two hoppers 3, and the refined powder is added to the two hoppers 3 through the powder adding pipe 2, and the refined powder in the two hoppers 3 falls into the tank body 1; a uniform discharging device 4 is used to make the refined powder in the tank body 1 uniformly discharged, and the uniform discharging device 4 includes a motor 41, which is installed on the top of the tank body 1, and the motor 41 is configured to be able to rotate forward and reverse, and a screw 42 is rotatably installed inside the tank body 1, and the top end of the screw 42 is connected to the output end of the motor 41 Then, the two hoppers 3 are respectively located on both sides of the screw 42, and a lifting plate 43 is slidably installed inside the tank body 1, and the lifting plate 43 is threadedly connected to the screw 42. When the screw 42 rotates forward, it drives the lifting plate 43 to slide upward in the tank body 1, and when the screw 42 rotates reversely, it drives the lifting plate 43 to slide downward in the tank body 1. The connection between the discharge pipe 8 and the tank body 1 is located above the lifting plate 43. In the process of refined powder being discharged from the tank body 1, the lifting plate 43 continues to rise, so that the top layer of the refined powder in the tank body 1 is always kept at the same height as the pipe mouth of the discharge pipe 8, so that the amount of refined powder entering the discharge pipe 8 is always kept in a relatively stable state, and the volume change of the air above the refined powder in the tank body 1 is small, so that the pressure in the tank body 1 is kept in a relatively stable state. The powder discharge amount of the discharge pipe 8 is relatively stable; a mounting ring 44 is installed on the inner wall of the tank body 1, and the mounting ring 44 is an open ring-shaped setting. Gear rods 45 are rotatably installed at both ends of the opening of the mounting ring 44. Two racks 46 are slidably connected to the inner wall of the tank body 1. The bottom ends of the two racks 46 are connected to the top surface of the lifting plate 43. The two racks 46 are respectively located on both sides of the connection between the discharge pipe 8 and the tank body 1. The two gear rods 45 are respectively meshed with the two gear rods 46. A cam 47 is connected to the end of the gear rod 45 away from the mounting ring 44. When the two racks 46 move upward, the two cams 47 are driven to rotate by the two gear rods 45. A polished rod 48 is connected between the two cams 47. The two cams 47 drive the polished rod 48 to rotate, and the discharge pipe 8 and the tank body 1 are connected. A cross wheel 49 is rotatably installed at the connection, a part of which is located in the discharge pipe 8, and four semicircular plates are arranged on the cross wheel 49, the four semicircular plates of the cross wheel 49 are of the same size, and the four semicircular plates are arranged in a circular array, the light rod 48 contacts with one of the semicircular plates of the cross wheel 49 during movement, and the light rod 48 drives the cross wheel 49 to rotate by shifting the semicircular plate on the cross wheel 49 when rotating, and when the cross wheel 49 rotates, the refined powder near the pipe opening of the discharge pipe 8 is intermittently pushed into the discharge pipe 8 through the four semicircular plates, and the amount of refined powder pushed into the discharge pipe 8 by each semicircular plate is relatively uniform, so that the refined powder is quantitatively sent into the discharge pipe 8 in batches, so that the refined powder conveying of the discharge pipe 8 is more uniform;After long-term use, the sealing between the lifting plate 43 and the inner wall of the tank body 1 becomes poor, causing part of the refined powder to fall through the gap into the space at the bottom of the lifting plate 43. This part of the refined powder is not easy to clean. After a long period of accumulation, it will hinder the lifting plate 43 from descending and cause waste of raw materials. A branch pipe 9 is connected between the bottom of the tank body 1 and the discharge pipe 8. A one-way cover 410 is rotatably installed at the connection between the branch pipe 9 and the tank body 1. The one-way cover 410 covers the connection between the branch pipe 9 and the tank body 1. Under normal circumstances, the one-way cover 410 covers the pipe opening of the branch pipe 9, and due to the pressure in the tank body 1, the one-way cover 410 is tightly fitted to the pipe opening of the branch pipe 9, which plays a sealing role. A pull rope 411 is connected between the one-way cover 410 and the lifting plate 43. When the lifting plate 43 is about to move to the highest point, the lifting plate 43 pulls up the one-way cover 410 through the pull rope 411. After the one-way cover 410 is opened, the refined powder located below the lifting plate 43 is transported to the discharge pipe 8 through the branch pipe 9. In the material pipe 8, the refined powder at the bottom of the lifting plate 43 can be sent to the discharge pipe 8 together with the refined powder every time the refined powder is transported, thereby avoiding the accumulation and waste of refined powder; through the setting of the uniform discharge device 4, the lifting plate 43 can rise according to the reduction of the refined powder volume in the tank body 1, so that the air pressure in the tank body 1 is kept in a stable state, and the top of the refined powder in the tank body 1 is always kept at the same height as the discharge pipe 8, so that the amount of refined powder entering the discharge pipe 8 is relatively stable; through the setting of the cross wheel 49, during the rising process of the lifting plate 43, the cross wheel 49 can push the refined powder in the tank body 1 into the discharge pipe 8 in batches by rotating, further improving the uniformity of the amount of refined powder entering the discharge pipe 8; when the refined powder above the lifting plate 43 is about to be transported, the pull rope 411 can pull up the one-way cover 410, so that the refined powder below the lifting plate 43 is transported to the discharge pipe 8 through the branch pipe 9, avoiding the accumulation of materials at the bottom of the tank body 1. ;

[0024] For further information, see Figure 8 - Fig.12The pushing device 5 is used to push the refined powder when discharging. The pushing device 5 includes two mounting frames 51, both of which are installed inside the tank body 1. The two mounting frames 51 are symmetrically arranged with the screw rod 42 as the center. The bottom of the two mounting frames 51 is slidably connected with a slide 52. The two mounting frames 51 limit the slide 52. The slide 52 can only slide left and right. The bottom of the slide 52 is connected with two slide slot frames 53. The inner walls of the two slide slot frames 53 are slidably connected to the outer wall of the light rod 48. When the light rod 48 rotates, the slide 52 is driven by the two slide slot frames 53 to slide back and forth on the two mounting frames 51. A plurality of fork frames 54 are respectively connected to both sides of the slide 52. The rotating mounting frames on the fork frames 54 Two push plates 55 are installed, and a limiting rod 56 is connected to the side of the fork frame 54 away from the slide frame 53. The limiting rod 56 on the fork frame 54 limits the two push plates 55, and the push plates 55 can only swing to the right but not to the left. When the slide frame 52 slides to the right, the multiple push plates 55 on the multiple fork frames 54 push the refined powder in the tank body 1 toward the direction of the discharge pipe 8. When the slide frame 52 slides to the left, the multiple push plates 55 on the multiple fork frames 54 are subjected to the reverse thrust of the refined powder and swing to the right, so that the multiple push plates 55 will not push the refined powder to the left, so that the refined powder in the tank body 1 can be continuously pushed to the right by the multiple push plates 55, avoiding the situation of piling up at a position away from the discharge pipe 8, thereby causing The mounting ring 44 is slidably connected to a push ring 57, which is located opposite to the slide frame 53. A fulcrum frame 58 is installed on the inner wall of the tank body 1. A rotating rod 59 rotates around the fulcrum frame 58. The fulcrum frame 58 is connected to a rotating rod 59 through a sliding hinge. One end of the rotating rod 59 is connected to an end of the slide frame 52 close to the fulcrum frame 58 through a sliding hinge. The other end of the rotating rod 59 is connected to the push ring 57 through a hinge. While the slide frame 52 reciprocates left and right, it can also use the lever principle to drive the push ring 57 to reciprocate left and right through the rotating rod 59. Two No. 2 rotating rods 510 are rotatably installed at the bottom of the mounting ring 44. The two No. 2 rotating rods 51 0 are rotated with the connection point with the bottom of the mounting ring 44 as the center of the circle, one end of the No. 2 rotating rod 510 is connected to the No. 1 push ring 57 through a sliding hinge, and the other end of the No. 2 rotating rod 510 is connected to the No. 2 push ring 511 through a sliding hinge, and the end of the No. 2 push ring 511 away from the No. 1 push ring 57 is rotatably connected to the mounting ring 44, and the two No. 2 push rings 511 are mirror-imaged. When the No. 1 push ring 57 reciprocates left and right, the two No. 2 rotating rods 510 are used to drive the two No. 2 push rings 511 to reciprocate around the connection point with the mounting ring 44 as the center by lever principle, and the No. 1 push ring 57 pushes the refined powder near the inner wall of the tank body 1 toward the direction close to the multiple push plates 55 through the cooperation with the two No. 2 push rings 511;By setting the pushing device 5, the multiple push plates 55 can continuously push the refined powder inside the tank body 1 toward the direction close to the discharge pipe 8 by reciprocating left and right, keep the top surface of the refined powder in the tank body 1 relatively flat, and keep the refined powder amount around the outlet of the discharge pipe 8 in a uniform state; by setting the No. 1 push ring 57 and the two No. 2 push rings 511, the No. 1 push ring 57 and the two No. 2 push rings 511 can continuously push the refined powder near the inner wall of the tank body 1 toward the direction close to the multiple push plates 55, promote the pushing effect, and avoid part of the refined powder from being closely attached to the inner wall of the tank body 1 and accumulating, resulting in the inability of local refined powder to be discharged from the tank body 1 in time. ;

[0025] Further, see Fig.13 - Fig.14 The anti-caking device 6 is used to break up the agglomerated refined powder. The anti-caking device 6 includes two movable frames 61, and the two movable frames 61 are respectively connected to the two sides of the slide frame 52. A plurality of cutters 62 are installed on the top surface of the movable frame 61. The two movable frames 61 are respectively located at the bottom of the two hoppers 3, and the cutters 62 are located inside the hopper 3. When the movable frame 61 reciprocates left and right, it drives the plurality of cutters 62 to reciprocate left and right. A sliding rod 64 is slidably installed on the inner wall of the hopper 3. There are a plurality of gaps between the movable frame 61 and the sliding rod 64. The refined powder in the hopper 3 falls through the plurality of gaps between the movable frame 61 and the sliding rod 64 during the falling process. The agglomerated refined powder will be blocked by the sliding rod 64 and the movable frame 61. One end of the movable frame 61 is hinged with a connecting rod 63, and the end of the connecting rod 63 away from the movable frame 61 is hinged with the sliding rod 64. When the movable frame 61 reciprocates left and right, the sliding rod 64 is driven to slide back and forth up and down through the connecting rod 63. A plurality of unblocking needles 65 are installed, and a plurality of cutters 62 can break up the refined powder blocks stuck on the movable frame 61 when they move back and forth left and right, so that the refined powder is cut and falls into the tank body 1. The plurality of unblocking needles 65 can promote the falling of the refined powder in the hopper 3 by moving back and forth up and down, avoid blockage in the hopper 3, and also can play the effect of breaking up larger lumps of refined powder; through the setting of the anti-caking device 6, the movable frame 61 and the slide bar 64 can screen the refined powder in the hopper 3 by cooperation, and the agglomerated refined powder is temporarily intercepted on the movable frame 61, and the agglomerates are broken up by the reciprocating movement of the plurality of cutters 62 left and right, and the falling of the refined powder in the hopper 3 is promoted by the reciprocating movement of the plurality of unblocking needles 65 up and down. The unblocking needles 65 can also break up larger lumps at the same time, avoid blockage in the hopper 3 due to the existence of lumps, and the lumps fall into the tank body 1 after being crushed, so as to avoid the agglomerated refined powder affecting the quality of subsequent processes.

[0026] Embodiment 2: A powder distribution method for an argon pressurized refined powder supply tank, using an argon pressurized refined powder supply tank in Embodiment 1, further comprising the following steps: Step 1: The motor 41 controls the screw rod 42 to reverse, so that the lifting plate 43 descends to the lowest position; Step 2: Open the valve of the powder adding pipe 2, feed the material through the powder adding pipe 2, and the powder adding pipe 2 adds the refined powder into the two hoppers 3 through two pipe openings, and the refined powder in the two hoppers 3 falls into the tank body 1; Step 3: Stop adding powder after the top layer of refined powder covers the outlet of the discharge pipe 8; Step 4: close the valve of the powder adding pipe 2, open the valve of the argon pipe 7, and add argon gas into the tank body 1 through the argon pipe 7 for pressurization; Step 5: Open the valve of the discharge pipe 8, control the screw 42 to rotate forward through the motor 41, and the lifting plate 43 rises slowly. During this process, the refined powder in the tank body 1 is transported to the subsequent equipment through the discharge pipe 8; Step 6: After the lifting plate 43 rises to the highest point, the valve of the branch pipe 9 is opened to transport the refined powder remaining at the bottom of the tank body 1 to the discharge pipe 8.

[0027] With the above structure, the working principle of this case is that the motor 41 is set to be able to rotate forward and reverse. When the motor 41 rotates, it drives the screw 42 to rotate. When the screw 42 rotates forward, it drives the lifting plate 43 to slide upward in the tank body 1. When the screw 42 reverses, it drives the lifting plate 43 to slide downward in the tank body 1. Before adding powder to the tank, the lifting plate 43 is first lowered to the lowest point, and the refined powder is added to the two hoppers 3 through the powder adding pipe 2. The refined powder in the two hoppers 3 falls into the tank body 1. When the refined powder is added to the same height as the outlet pipe 8, it is pressurized through the argon pipe 7, the motor 41 is started to rotate forward, and the screw 42 rotates forward to drive the lifting plate 43 to rise. The refined powder in the tank body 1 enters the outlet pipe 8 using the positive pressure principle, and then is discharged through the outlet pipe 8. The refined powder is sent to the subsequent process. In the process of the refined powder being discharged from the tank body 1, the lifting plate 43 rises continuously, so that the top layer of the refined powder in the tank body 1 is always kept at the same height as the nozzle of the discharge pipe 8, so that the amount of refined powder entering the discharge pipe 8 is always kept in a relatively stable state, and the volume change of the air above the refined powder in the tank body 1 is small, so that the pressure in the tank body 1 is kept in a relatively stable state, and the powder discharge amount of the discharge pipe 8 is relatively stable; in the process of the lifting plate 43 moving upward, the lifting plate 43 drives the two racks 46 to move upward, and when the two racks 46 move upward, they drive the two gear rods 45 to rotate, and the two gear rods 45 drive the two cams 47 to rotate, and the two cams 47 drive the light rod 48 to rotate, and when the light rod 48 rotates, The cross wheel 49 is driven to rotate by toggling the upper semicircular plate of the cross wheel 49. When the cross wheel 49 rotates, the refined powder near the outlet of the discharge pipe 8 is intermittently pushed into the discharge pipe 8 through the four semicircular plates. Since the four semicircular plates of the cross wheel 49 are of the same size and are arranged in a circular array, the amount of refined powder pushed into the discharge pipe 8 by each semicircular plate is relatively uniform, so that the refined powder is quantitatively sent into the discharge pipe 8 in batches, and the refined powder transportation of the discharge pipe 8 is more uniform. After long-term use, the sealing between the lifting plate 43 and the inner wall of the tank body 1 becomes worse, causing part of the refined powder to fall through the gap into the space at the bottom of the lifting plate 43. This part of the refined powder is not easy to clean. After long-term accumulation, The lifting plate 43 is prevented from descending and the raw materials are wasted. When the lifting plate 43 is about to move to the highest point, the lifting plate 43 straightens the pull rope 411. Under normal conditions, the one-way cover 410 covers the pipe opening of the branch pipe 9, and due to the pressure in the tank body 1, the one-way cover 410 is tightly fitted to the pipe opening of the branch pipe 9, which plays a sealing role. When the pull rope 411 is straightened, the lifting plate 43 continues to rise, so that the lifting plate 43 pulls up the one-way cover 410 through the pull rope 411. After the one-way cover 410 is opened, the refined powder under the lifting plate 43 is transported to the discharge pipe 8 through the branch pipe 9, so that the refined powder at the bottom of the lifting plate 43 can be sent to the discharge pipe 8 together with the refined powder each time the refined powder is transported, thereby avoiding the accumulation and waste of refined powder.By setting the uniform discharge device 4, the lifting plate 43 can rise according to the reduction of the refined powder volume in the tank body 1, so that the air pressure in the tank body 1 is kept in a stable state, and the top of the refined powder in the tank body 1 is always kept at the same height as the discharge pipe 8, so that the amount of refined powder entering the discharge pipe 8 is relatively stable; by setting the cross wheel 49, during the lifting of the lifting plate 43, the cross wheel 49 can push the refined powder in the tank body 1 into the discharge pipe 8 in batches by rotating, further improving the uniformity of the refined powder entering the discharge pipe 8; when the refined powder above the lifting plate 43 is about to be transported, the pull rope 411 can pull up the one-way cover 410, so that the refined powder below the lifting plate 43 is transported to the discharge pipe 8 through the branch pipe 9, avoiding the accumulation of materials at the bottom of the tank body 1. ;

[0028] The two mounting frames 51 limit the slide 52, and the slide 52 can only slide left and right. When the light rod 48 rotates, the two slide slot frames 53 drive the slide 52 to slide back and forth on the two mounting frames 51. The slide 52 drives multiple fork-shaped frames 54 on both sides to slide back and forth. The limiting rods 56 on the fork-shaped frames 54 limit the two push plates 55, and the push plates 55 can only swing to the right but not to the left. When the slide 52 slides to the right, the multiple push plates 55 on the multiple fork-shaped frames 54 push the refined powder in the tank body 1 toward the direction of the discharge pipe 8. When the slide 52 slides to the left, the multiple push plates 55 on the multiple fork-shaped frames 54 swing to the right due to the reverse thrust of the refined powder, so that the multiple The push plate 55 will not push the refined powder to the left, so that the refined powder in the tank body 1 can be continuously pushed to the right by multiple push plates 55, avoiding the situation that the material is piled up at a position far away from the discharge pipe 8, thereby causing uneven discharge; the mounting ring 44 limits the No. 1 push ring 57, and the No. 1 push ring 57 can only slide left and right. The No. 1 rotating rod 59 rotates around the fulcrum frame 58. When the slide 52 moves to the left, the lever principle is used to push the No. 1 push ring 57 to the right through the No. 1 rotating rod 59, so that the slide 52 can reciprocate left and right while also driving the No. 1 push ring 57 to reciprocate left and right through the No. 1 rotating rod 59. The two No. 2 rotating rods 510 are both connected to the bottom of the mounting ring 44 at their connection points. The center of the circle rotates, and when the No. 1 push ring 57 moves to the left, the two No. 2 rotating rods 510 use the lever principle to pull the ends of the two No. 2 push rings 511 close to the No. 1 push ring 57 toward the direction close to the screw 42. When the No. 1 push ring 57 moves to the right, the two No. 2 rotating rods 510 use the lever principle to pull the ends of the two No. 2 push rings 511 close to the No. 1 push ring 57 away from the screw 42. When the No. 1 push ring 57 reciprocates left and right, the two No. 2 rotating rods 510 drive the two No. 2 push rings 511 to reciprocate around the connection point with the mounting ring 44 as the center. The No. 1 push ring 57 cooperates with the two No. 2 push rings 511 to push the refined powder near the inner wall of the tank body 1 toward Push in the direction close to multiple push plates 55; through the setting of the pushing device 5, the multiple push plates 55 can continuously push the refined powder inside the tank body 1 towards the direction close to the discharge pipe 8 by reciprocating left and right, keeping the top surface of the refined powder in the tank body 1 relatively flat, and keeping the amount of refined powder around the pipe mouth of the discharge pipe 8 in a uniform state; through the setting of the No. 1 push ring 57 and the two No. 2 push rings 511, the No. 1 push ring 57 and the two No. 2 push rings 511 can continuously push the refined powder close to the inner wall of the tank body 1 towards the direction close to the multiple push plates 55, thereby promoting the pushing effect and avoiding the accumulation of part of the refined powder close to the inner wall of the tank body 1, which causes the local refined powder to be unable to be discharged from the tank body 1 in time.

[0029] There are multiple gaps between the movable frame 61 and the slide bar 64 in the hopper 3. The refined powder in the hopper 3 falls through the multiple gaps between the movable frame 61 and the slide bar 64 during the falling process. When there are lumps in the refined powder, the lumped refined powder will be blocked by the slide bar 64 and the movable frame 61. When the slide 52 reciprocates left and right, it drives the two movable frames 61 to reciprocate left and right. When the movable frame 61 reciprocates left and right, it drives multiple cutters 62 to reciprocate left and right. The hopper 3 limits the slide bar 64, and the slide bar 64 can only slide up and down. When the movable frame 61 reciprocates left and right, the connecting rod 63 drives the slide bar 64 to slide up and down. The slide bar 64 drives multiple dredging needles 65 to reciprocate up and down. When the multiple cutters 62 reciprocate left and right, they can cut the refined powder blocks stuck on the movable frame 61 into pieces. The refined powder is cut into pieces and then falls into the tank body 1. The multiple unblocking needles 65 can promote the falling of the refined powder in the hopper 3 by reciprocating up and down, avoid material blockage in the hopper 3, and also can break up the larger lumps of refined powder. Through the setting of the anti-caking device 6, the movable frame 61 and the slide bar 64 cooperate to screen the refined powder in the hopper 3, and the agglomerated refined powder is temporarily intercepted on the movable frame 61. The agglomerates are cut into pieces by the reciprocating left and right movements of the multiple cutters 62. The falling of the refined powder in the hopper 3 is promoted by the reciprocating up and down movements of the multiple unblocking needles 65. The unblocking needles 65 can also break up the larger lumps to avoid material blockage caused by the existence of lumps in the hopper 3. The lumps are crushed and then fall into the tank body 1, avoiding the agglomeration of refined powder affecting the quality of subsequent processes.
