Description

Technical Field

[0001] The present invention relates to the technical field of metal processing, in particular to a drying mechanism for precious metal solid-liquid separation. Background Art

[0002] Precious metals refer to a class of metallic elements that are rare in the Earth's crust, have stable physical and chemical properties, and have extremely high economic value. They mainly include gold, silver, ruthenium, rhodium, palladium, osmium, iridium, and platinum, a total of eight precious metals. Precious metals are considered "precious" because of their rarity, corrosion resistance, good electrical and thermal conductivity, and wide range of applications.

[0003] A precious metal drying system is a device specifically designed for filtering, washing, and drying precious metal powders. This equipment is commonly referred to as a gold and silver precious metal powder filter-washer-dryer or a conical three-in-one filter-dryer. It is primarily used to process coarse silver powder, hydrazine hydrate gold powder, gold salts, silver salts, and other precious metal powders, ensuring they reach the required dryness before subsequent processing.

[0004] Existing precious metal drying mechanisms are unable to effectively disperse metal powders by rotating or stirring during the drying process, resulting in insufficient flow and accumulation of metal powders in dead corners, slowing down the thermal drying process. At the same time, due to the small particle size of metal powders, agglomeration is prone to occur, making it difficult for internal moisture to evaporate quickly, extending the drying time and affecting production quality. Moreover, during the drying process of metal powders, the interaction force between powder particles is prone to form hard agglomerates, destroying the dispersibility of the powder, and further affecting the efficiency of the drying operation. Therefore, the present application provides a drying mechanism for precious metal solid-liquid separation to meet the needs. Summary of the Invention

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] In the above scheme, by setting up a vibration adjustment component, the vibration motor drives the movable rod to vibrate through the vibration rod, so that the metal powder dropped onto the arc-shaped impact plate is subjected to continuous impact force, thereby improving the dispersion of the powder and reducing the agglomeration phenomenon. The vibration impact causes the powder particles to continuously turn over, increasing the contact area with the hot air inside the drying barrel and shortening the drying time. At the same time, the spring can stabilize the vibration frequency, avoid energy loss, and ensure the continuous and uniform transmission of the impact force. Moreover, the dynamic impact of the arc-shaped impact plate can suppress the densification of the powder under pressure and the occurrence of hard agglomeration. Combined with the vibration motor with adjustable parameters, the adaptability of the drying mechanism is enhanced, and the drying process suitable for different metal powders is improved.

[0019] By setting up an air supply adjustment component, multiple groups of hollow air ducts can realize the circulating airflow formed by sucking the tail of the metal powder inside the drying barrel into the front end and ejecting it, so that the metal powder is fully suspended in the airflow to avoid accumulation in dead corners. At the same time, the metal powder hits the inclined plate through the length difference to form turbulence, destroying the powder agglomeration structure, and the internal heating pipe and the impact inclined plate are staggered, which extends the airflow path and increases the contact time between the metal powder and the heat pipe. The drying rate is further improved, and the inclined plate reflects the airflow to form a local vortex, so that the powder particles repeatedly pass through the high-temperature area, the evaporation rate of water is accelerated, and the closed-loop air supply system reduces heat loss. Combined with the internal heating pipe, the inert gas circulating air supply can simultaneously achieve drying and anti-oxidation.

[0020] By setting up a material collection adjustment component, the directional airflow of the air duct driven by the wind fan acts on the oblique opening conical hopper to eliminate the accumulation of metal powder in the dead corner, thereby improving the drying efficiency and uniformity. In addition, the temperature and humidity inside the drying barrel are monitored by the temperature and humidity sensor to dynamically adjust the opening and closing of the material collection adjustment component until the metal powder inside the drying barrel reaches the optimal dry state. The metal powder is then collected to ensure the quality of the metal powder drying process. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] like Figures 1 to 13As shown, an embodiment of the present invention provides a drying mechanism for solid-liquid separation of precious metals, including a mounting bracket 1, the top of the mounting bracket 1 is fixedly connected to a drying barrel 2, the bottom of the drying barrel 2 is fixedly connected to a cone hopper 3, the end of the cone hopper 3 is fixedly connected to a discharge port 4, the end of the drying barrel 2 is bolted to a control chassis 5, the top end of the drying barrel 2 is plugged with a feed port 9, the interior of the drying barrel 2 is sleeved with a spiral heating tube 10, the bottom of the cone hopper 3 is fixedly connected to a vibration adjustment component 6, the vibration adjustment component 6 is used to vibrate the metal inside the drying barrel 2, and the vibration adjustment component 6 is connected to the cone hopper 3; an air supply adjustment component 7, the air supply adjustment component 7 is used to circulate and blow the metal powder in the drying barrel 2, and the air supply adjustment component 7 is connected to the drying barrel 2; a material collection adjustment component 8, the material collection adjustment component 8 is used to collect the metal powder in the drying barrel 2, and the material collection adjustment component 8 is connected to the drying barrel 2.

[0044] As an implementation method in this embodiment, Figures 4 to 7As shown, the vibration adjustment component 6 includes a vibration motor 61 fixedly connected to the bottom of the cone bucket 3, a vibration rod 62 is fixedly connected to the top of the vibration motor 61, a hole is opened inside the top of the vibration rod 62, a sleeve 63 is sleeved on the top surface of the vibration rod 62, a movable rod 64 is inserted on the top of the vibration rod 62, and an arc-shaped impact plate 66 is installed on the top of the movable rod 64. The arc-shaped impact plate 66 is a curved circular plate, and a spring 65 is sleeved on the surface of the movable rod 64. The two ends of the spring 65 are respectively fixedly connected to the bottom of the arc-shaped impact plate 66 and the top of the vibration rod 62. The bottom of the arc-shaped impact plate 66 is fixedly connected to a corrugated hose 67, which is made of stainless steel. When the metal powder enters the interior of the drying barrel 2, the vibration adjustment component 6 starts to run, and the vibration motor 61 is started. The working parameters of the vibration motor 61 are set according to the production indicators of the required metal. As the vibration motor 61 starts, the vibration rod 62 fixedly connected to the top of the vibration motor 61 begins to vibrate inside the sleeve 63. As the vibration rod 62 starts to vibrate, the movable rod 64 inserted at the top of the vibration rod 62 starts to vibrate. Operation, at this time, with the movement of the movable rod 64, the arc-shaped impact plate 66 fixedly connected to the top of the movable rod 64 begins to receive the vibration energy transmitted by the movable rod 64 and performs synchronous vibration impact, and at the same time, the movement of the arc-shaped impact plate 66 causes the spring 65 fixedly connected to the bottom of the arc-shaped impact plate 66 to move together with the arc-shaped impact plate 66. At this time, the spring 65 contracts and releases between the vibration rod 62 and the arc-shaped impact plate 66. With the stable vibration frequency of the spring 65, energy loss is avoided, ensuring that the impact force is continuously and evenly transmitted to the arc-shaped impact plate Plate 66, and then the arc-shaped impact plate 66 impacts the metal powder again to avoid the occurrence of metal powder agglomeration and, at the same time, improve the dispersion of the metal powder. Moreover, while the arc-shaped impact plate 66 moves, the corrugated hose 67 fixedly connected to the bottom of the arc-shaped impact plate 66 contracts synchronously. At this time, the corrugated hose 67 is sleeved on the inner wall of the oblique-opening conical bucket 81 and wraps the vibration adjustment component 6 from the bottom of the arc-shaped impact plate 66 to the surface of the oblique-opening conical bucket 81 to prevent the entry of metal powder and reduce the loss of metal powder to the vibration adjustment component 6.

[0045] As an implementation method in this embodiment, Figures 7 to 10As shown, the air supply adjustment component 7 includes a mounting base 71 fixedly connected to the top of the drying barrel 2, a temperature and humidity sensor 72 is inserted into the interior of the mounting base 71, a plurality of groups of air boxes 73 are fixedly connected to the four ends of the top of the drying barrel 2, the bottoms of the plurality of groups of air boxes 73 are fixedly connected to an air supply pipe 74, the top of the air supply pipe 74 is fixedly connected to a hollow air duct 75, the hollow air duct 75 is cylindrical, and the interior of the hollow air duct 75 is hollow, the right end of the hollow air duct 75 is fixedly connected to a wind shield ring 76, the left end of the hollow air duct 75 is fixedly connected to a ventilation ring 77, the ventilation ring 77 consists of two groups of circular rings of different sizes, the inner wall of the ventilation ring 77 is fixedly connected to a plurality of double-angled air dividing blocks 78, and the plurality of double-angled air dividing blocks 78 are arranged in two groups of different sizes in the ventilation ring 77. The inner wall of the hollow air duct 75 is evenly distributed, and multiple groups of impact inclined plates 79 are fixedly connected to the inner wall of the hollow air duct 75. The multiple groups of impact inclined plates 79 are composed of multiple blocking blocks with successively increasing lengths. The inner wall of the hollow air duct 75 is also fixedly connected with multiple internal heating tubes 710. The multiple internal heating tubes 710 and the multiple groups of impact inclined plates 79 are staggeredly installed around the hollow air duct 75. The ends of the multiple internal heating tubes 710 are installed with blocking nets 711. The interiors of the multiple internal heating tubes 710 are fixedly connected with heating coils 712. When the air supply adjustment component 7 starts to operate, the temperature and humidity sensor 72 plugged into the mounting base 71 starts to operate, and the real-time temperature and humidity inside the drying barrel 2 are detected at all times to ensure the production accuracy of the metal powder drying process. At the same time, the metal powder is kept in a constant state. At the end, the air enters the drying barrel 2, and the multiple groups of wind boxes 73 fixedly connected to the top of the drying barrel 2 start to operate and start to provide wind support. At any time, the multiple groups of wind boxes 73 start to operate, and the air supply pipe 74 fixedly connected to the bottom of the wind box 73 sends the wind to the inside of the hollow air duct 75 fixedly connected to the bottom of the air supply pipe 74. Due to the internal empty slot of the circular hollow air duct 75, the wind sent by the wind box 73 is blown to both sides. At the same time, it is blocked by the wind shield ring 76 fixedly connected to the right end of the hollow air duct 75, so that the wind sent by the air supply pipe 74 is blown to the left end of the hollow air duct 75. At this time, the wind inside the hollow air duct 75 passes through the ventilation ring 77 at the left end of the hollow air duct 75 to the interior of the drying barrel 2. At the same time, it is affected by the multiple groups of double-angle air dividing blocks 78 installed on the ventilation ring 77. The wind force is segmented, and multiple groups of double-diamond-shaped wind dividing blocks 78 accelerate the wind passing through the ventilation ring 77, realizing the Venturi effect and speeding up the transmission of wind force. At this time, as the wind force blows into the interior of the drying barrel 2 through the ventilation ring 77, drainage is generated between the hollow air ducts 75, sucking the metal powder dispersed in the drying barrel 2 into from one end of the wind shield ring 76 and flying out from one end of the ventilation ring 77. At the same time, the flying metal powder hits the impact inclined plates 79 of different lengths and is ejected to break up the agglomerated powder, while increasing the heat contact surface. In addition, the internal heating tube 710 fixedly connected to the inner wall of the hollow air duct 75 reheats the incoming metal powder through the heating coil 712, and the blocking net 711 intercepts the entry of the metal powder.To speed up the drying process of metal powder, the air supply adjustment component 7 cooperates with the vibration adjustment component 6 to continuously suck in and blow out the metal powder dispersed inside the drying barrel 2, in a reciprocating cycle, speeding up the drying process of metal powder and improving production quality.

[0046] As an implementation method in this embodiment, Figures 7 to 13As shown, the material receiving and adjusting assembly 8 includes an oblique opening conical bucket 81 fixedly connected to the inner wall of the drying barrel 2, a sleeve 63 is inserted at the axis of the oblique opening conical bucket 81, the inner wall surface of the oblique opening conical bucket 81 is fixedly connected to the bottom of the corrugated hose 67, a plurality of air ducts 82 are inserted at the end of the drying barrel 2, and wind fans 83 are installed at the ends of the plurality of air ducts 82. The bottom opening of the oblique opening conical bucket 81 is fixedly connected to a sliding cabinet cavity 84, and the inner ends of the sliding cabinet cavity 84 are provided with slide rails, and the bottom of the sliding cabinet cavity 84 is provided with a hole groove. The interior of the sliding cabinet cavity 84 is slidably connected to a covering plate 86, and the size of the covering plate 86 is consistent with the size of the bottom opening of the oblique opening conical bucket 81. The bottom of the sliding cabinet cavity 84 is fixedly connected There is a discharge pipe 85, the end of the cover plate 86 is fixedly connected to a push rod 810, the end of the push rod 810 is fixedly connected to a connecting rod 89, the bottom of the connecting rod 89 is fixedly connected to a driving base 88, the end of the driving base 88 is fixedly connected to a hydraulic cylinder 87, and the hydraulic cylinder 87 is installed at the end of the discharge pipe 85 at the bottom of the sliding cabinet cavity 84. When the metal powder enters the drying barrel 2, the material collecting and adjusting component 8 starts to run. At this time, the wind fan 83 fixedly connected to the end of the air duct 82 starts to run. As the wind fan 83 runs, the wind force generated by the operation acts on the oblique opening conical bucket 81 through the air duct 82 plugged into one end of the drying barrel 2. The air duct 82 transports the wind force generated by the wind fan 83 to the surface of the oblique opening conical bucket 81. After the surface, the metal powder on the surface of the oblique opening conical bucket 81 begins to float under the action of the wind, away from the surface of the oblique opening conical bucket 81, and then the metal powder fluttering in the drying barrel 2 is sucked into the air supply adjustment component 7, and then blown into the drying barrel 2. The metal powder blown out by the air supply adjustment component 7 falls on the arc impact plate 66 and the oblique opening conical bucket 81, and then the arc impact plate 66 continues to impact the metal powder, and the air duct 82 continues to supply air, and the reciprocating operation is performed until the temperature and humidity sensor 72 detects that the metal powder in the drying barrel 2 meets the drying treatment result. The temperature and humidity sensor 72 transmits an electrical signal to the control box 5, and then the air supply adjustment component 7 slowly stops running, and the metal powder inside the drying barrel 2 begins to After the hydraulic cylinder 87 is fixedly connected to the bottom of the sliding cabinet cavity 84, it starts to operate, and the output end of the hydraulic cylinder 87 starts to drive. Then, the driving base 88 fixedly connected to the output end of the hydraulic cylinder 87 moves. As the driving base 88 moves, the connecting rod 89 fixedly connected to one end of the driving base 88 moves synchronously. At this time, as the connecting rod 89 moves, the push rod 810 fixedly connected to the end of the connecting rod 89 drives the end fixedly connected covering plate 86 to move toward the direction of the hydraulic cylinder 87. As the covering plate 86 moves, the opening at the bottom of the oblique opening conical bucket 81 is opened, and then the metal powder begins to flow continuously toward the lower feeding pipe 85, and then the metal powder in the feeding pipe 85 continues to flow and is finally discharged from the feeding port 4.

[0047] The working principle of the technical solution provided by the present invention is as follows:

[0048] When using this device, first start the spiral heating tube 10 installed inside the drying barrel 2 for preheating, then add the precious metal powder after solid-liquid separation through the feed port 9 plugged into one end of the top of the drying barrel 2. When the precious metal powder enters the interior of the drying barrel 2, the vibration adjustment component 6 starts to operate.

[0049] After the metal powder enters the interior of the drying barrel 2, the vibration adjustment component 6 starts to operate, and the vibration motor 61 is started at this time. The working parameters of the vibration motor 61 are set according to the production indicators of the required metal. As the vibration motor 61 is started, the vibration rod 62 fixedly connected to the top of the vibration motor 61 begins to conduct vibration inside the sleeve 63. As the vibration rod 62 starts to vibrate, the movable rod 64 inserted at the top of the vibration rod 62 starts to operate. At this time, as the movable rod 64 moves, the arc impact plate 66 fixedly connected to the top of the movable rod 64 begins to receive the vibration energy transmitted by the movable rod 64 and performs synchronous vibration impact. At the same time, the movement of the arc impact plate 66 causes the spring 65 fixedly connected to the bottom of the arc impact plate 66 to move together with the arc impact plate 66. At this time, the spring 65 contracts and releases between the vibration rod 62 and the arc-shaped impact plate 66. With the stable vibration frequency of the spring 65, energy loss is avoided, ensuring that the impact force is continuously and evenly transmitted to the arc-shaped impact plate 66. Then the arc-shaped impact plate 66 impacts the metal powder again to avoid the occurrence of metal powder agglomeration. At the same time, the dispersion of the metal powder is improved. Moreover, while the arc-shaped impact plate 66 moves, the corrugated hose 67 fixedly connected to the bottom of the arc-shaped impact plate 66 contracts synchronously. At this time, the corrugated hose 67 is sleeved on the inner wall of the oblique opening conical bucket 81 and wraps the vibration adjustment component 6 from the bottom of the arc-shaped impact plate 66 to the surface of the oblique opening conical bucket 81 to prevent the entry of metal powder and reduce the loss of metal powder to the vibration adjustment component 6.

[0050] At the same time, as the metal powder enters the drying barrel 2, the air supply adjustment component 7 starts to operate. At this time, the temperature and humidity sensor 72 plugged into the mounting base 71 starts to operate, constantly detecting the real-time temperature and humidity inside the drying barrel 2 to ensure the production accuracy of the metal powder drying process. At the same time, as the metal powder enters the drying barrel 2, the multiple groups of wind boxes 73 fixedly connected to the top of the drying barrel 2 start to operate and start to provide wind support. At any time, the operation of the multiple groups of wind boxes 73, fixedly connected to the wind boxes The air supply pipe 74 at the bottom of the air supply pipe 73 sends wind to the interior of the hollow air pipe 75 fixedly connected to the bottom of the air supply pipe 74. Due to the internal slot of the circular hollow air pipe 75, the wind sent by the bellows 73 is blown to both sides. At the same time, it is blocked by the wind shield ring 76 fixedly connected to the right end of the hollow air pipe 75, so that the wind sent by the air supply pipe 74 is blown to the left end of the hollow air pipe 75. At this time, the wind inside the hollow air pipe 75 passes through the ventilation ring 77 at the left end of the hollow air pipe 75 to the interior of the drying barrel 2. At the same time, it is blocked by the wind shield ring 76 installed on the ventilation ring 77. The wind is segmented by the multiple sets of double-angled wind dividing blocks 78. Moreover, the multiple sets of double-angled wind dividing blocks 78 accelerate the wind passing through the ventilation ring 77, realizing the Venturi effect and speeding up the transmission of wind. At this time, as the wind blows into the interior of the drying barrel 2 through the ventilation ring 77, drainage is generated between the hollow air ducts 75, sucking the metal powder dispersed in the drying barrel 2 into from one end of the wind shield ring 76 and flying out from one end of the ventilation ring 77. At the same time, the flying metal powder hits the impact ramps of different lengths. After being put on 79, it is ejected to break up the agglomerated powder and at the same time increase the heated contact surface. In addition, the internal heating tube 710 fixedly connected to the inner wall of the hollow air duct 75 reheats the incoming metal powder through the heating coil 712. At the same time, the baffle 711 intercepts the entry of the metal powder and accelerates the drying process of the metal powder. At this time, the air supply adjustment component 7 cooperates with the vibration adjustment component 6 to continuously inhale and blow out the metal powder dispersed in the interior of the drying barrel 2, and repeat the cycle to accelerate the drying process of the metal powder and improve the production quality.

[0051] When the metal powder enters the drying barrel 2, the collecting and regulating assembly 8 starts to operate. At this time, the wind fan 83 fixedly connected to the end of the air duct 82 starts to operate. As the wind fan 83 operates, the wind force acts on the oblique opening conical bucket 81 through the air duct 82 plugged into one end of the drying barrel 2. After the air duct 82 transports the wind force driven by the wind fan 83 to the surface of the oblique opening conical bucket 81, the metal powder on the surface of the oblique opening conical bucket 81 begins to float under the action of the wind force, away from the surface of the oblique opening conical bucket 81, and then The metal powder flying in the drying barrel 2 is sucked in by the air supply regulating component 7 and then blown into the drying barrel 2. The metal powder blown out by the air supply regulating component 7 falls on the arc impact plate 66 and the oblique opening conical bucket 81. Then the arc impact plate 66 continues to impact the metal powder, and the air duct 82 continues to supply air. The reciprocating operation is carried out until the temperature and humidity sensor 72 detects that the metal powder in the drying barrel 2 meets the drying treatment result. The temperature and humidity sensor 72 transmits an electrical signal to the control box 5, and then the air supply regulating component 7 slowly stops. The operation of the hydraulic cylinder 87 starts the metal powder inside the drying barrel 2 to settle, and then the hydraulic cylinder 87 fixedly connected to the bottom of the sliding cabinet cavity 84 starts to operate, and the output end of the hydraulic cylinder 87 starts to drive, and then the driving base 88 fixedly connected to the output end of the hydraulic cylinder 87 moves. As the driving base 88 moves, the connecting rod 89 fixedly connected to one end of the driving base 88 moves synchronously. At this time, as the connecting rod 89 moves, the push rod 810 fixedly connected to the end of the connecting rod 89 drives the end fixedly connected covering plate 86 to move in the direction of the hydraulic cylinder 87. As the covering plate 86 moves, the opening at the bottom of the oblique opening conical bucket 81 is opened, and then the metal powder begins to flow continuously to the lower feeding pipe 85, and then the metal powder in the feeding pipe 85 continues to flow and is finally discharged from the feeding port 4. As the metal powder is discharged, the vibration adjustment component 6 continues to work. At this time, the vibration generated by the vibration adjustment component 6 accelerates the circulation of the metal powder. At the same time, the vibration effect is reduced, and the accumulation of metal powder inside the drying barrel 2 is improved, while reducing production losses.
