Description

Technical Field

[0001] This utility model belongs to the field of silver powder production technology, and in particular relates to a clean suction filtration device for silver powder production. Background Technology

[0002] Silver powder is a precious metal powder material that is widely used and consumed in large quantities in the electronics industry. Due to its high conductivity and good physicochemical properties, it is widely used in photovoltaics, 5G communications, semiconductors and other fields. At the same time, during the processing and production of silver powder, dust is easily attached to its surface. In order to clean silver powder, a vacuum filtration device is usually used.

[0003] The cleaning and filtration devices for silver powder currently available on the market have the following problems when used:

[0004] 1. In traditional vacuum filtration devices, the silver powder to be cleaned is usually placed inside the Buchner funnel, and then the air pump is started to draw air to complete the vacuum filtration. However, if too much silver powder is poured in during the vacuum filtration process, the silver powder near the top layer may not be able to contact the ultrafiltration membrane, and thus cannot be filtered effectively. It is necessary to manually insert a tool similar to a stirring rod to stir it, which is quite troublesome to operate.

[0005] 2. In most vacuum filtration devices, the inside of the filtration container is used to store liquid and mixed impurities. After use, it needs to be emptied and cleaned by the staff. However, under normal circumstances, it is not easy for the staff to pour out the liquid mixture and clean it up, which is inconvenient to operate. Utility Model Content

[0006] The purpose of this invention is to provide a clean filtration device for silver powder production, so as to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, the specific technical solution of this utility model is as follows: A clean filtration device for silver powder production includes a device body, a vacuum pump, and a Buchner funnel. A fixed base is provided on the top of the device body, and the Buchner funnel is installed on the top of the fixed base. A base plate is provided at the bottom of the device body. An agitating plate is provided inside the Buchner funnel. A support plate is fixedly connected to the top of the device body. A horizontal plate is connected to the top of the support plate through a rotating shaft. A rotating shaft seat is installed on the top of the horizontal plate. A pull rod is movably inserted inside the rotating shaft seat. An agitating plate is provided at the bottom of the pull rod. A strip plate is fixedly connected to the top of the pull rod. A rotating handle is provided on the top of the strip plate.

[0008] Preferably, a water storage box is embedded inside the device body, and an outer sealing frame is fixedly connected to the outside of the water storage box. The outer sealing frame is sleeved on the outside of the device body, and an insert is fixedly connected to the bottom of the outer sealing frame. A slot is opened on the top of the base plate, and the insert is embedded in the slot.

[0009] Preferably, a reinforcing plate is embedded in the bottom of the pull rod, and a stirring plate is fixedly connected to the bottom of the reinforcing plate. The stirring plate is trapezoidal in shape.

[0010] Preferably, the top of the fixing seat is provided with a sealing ring, and the Buchner funnel is embedded inside the sealing ring.

[0011] Preferably, an ultrafiltration membrane is placed inside the Buchner funnel, the agitator is suspended above the ultrafiltration membrane, and the bottom of the Buchner funnel is placed inside the fixed base.

[0012] Preferably, the device body has a connector on its side, a flexible hose is sleeved on the outside of the connector, an air pump is provided on the top of the base plate, an air pump head is provided on the top of the air pump, and a flexible hose is sleeved on the outside of the air pump head.

[0013] The cleaning and filtration device for silver powder production according to this invention has the following advantages:

[0014] 1. This cleaning and filtration device for silver powder production features a stirring plate structure installed above a Buchner funnel. The stirring plate is designed to be able to be pulled up and down. When too much silver powder is poured in, causing poor filtration of the silver powder near the top layer, the stirring plate can be lowered and placed inside the silver powder mixture. Then, the handle is rotated at a constant speed, causing the pull rod and the bottom stirring plate to rotate, thus thoroughly stirring the accumulated silver powder. This allows the silver powder in the upper layer to change position and be fully mixed, facilitating the filtration process. The entire process eliminates the need for workers to find additional stirring tools, and the overall structure is simple and convenient to use.

[0015] 2. This cleaning and filtration device for silver powder production features an embedded water storage box at the bottom of the device body, made of hard rubber. During use, the water storage box is embedded inside the device body, and the liquid falls into the water storage box during filtration. When the filtration is complete and the filtered liquid mixture needs to be cleaned, simply pull the device body upwards to detach it from the water storage box, allowing the liquid mixture inside the water storage box to be poured out separately. This detachable and modular design greatly facilitates the handling of the filtered liquid mixture by operators, saving time and effort during operation. Attached Figure Description

[0025] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a cleaning and filtration device for silver powder production.

[0026] like Figure 1-4 As shown, this utility model discloses a cleaning and filtration device for silver powder production, comprising a device body 1, a vacuum pump 17, and a Buchner funnel 5. A fixed base 3 is provided on the top of the device body 1, and the Buchner funnel 5 is mounted on the top of the fixed base 3. A base plate 2 is provided at the bottom of the device body 1. A stirring plate 14 is provided inside the Buchner funnel 5. A support plate 7 is fixedly connected to the top of the device body 1. A horizontal plate 8 is connected to the top of the support plate 7 via a rotating shaft. A rotating shaft seat 11 is mounted on the top of the horizontal plate 8. Due to the rotating shaft seat 11, a pull rod 10 is movably inserted inside the rotating shaft seat 11. The bottom of the pull rod 10 is provided with the stirring plate 14, and a strip-shaped... Plate 12, the top of which is equipped with a rotating handle 13, and by installing a stirring plate 14 above the Buchner funnel 5, the accumulated silver powder can be stirred and mixed, thus avoiding excessive accumulation and clogging. Since the stirring plate 14 is a pull-up and pull-down style, it can be lowered and placed inside the silver powder mixture during use. Then, the rotating handle 13 is rotated at a constant speed, thereby driving the pull rod 10 and the bottom stirring plate 14 to rotate, thus fully stirring the accumulated silver powder. This allows the upper layer of silver powder to change position and be fully mixed, which can better facilitate the filtration work and is more convenient to use.

[0027] The device body 1 has a water storage box 18 embedded inside, and an outer sealing frame 19 is fixedly connected to the outside of the water storage box 18. The outer sealing frame 19 is fitted onto the outside of the device body 1, and an insert block 20 is fixedly connected to the bottom of the outer sealing frame 19. A slot 21 is opened on the top of the base plate 2, and the insert block 20 is embedded in the slot 21. Since the device body 1 has an embedded water storage box 18 at the bottom, and the water storage box 18 is made of hard rubber material, when the filtration work is completed and the filtered liquid mixture needs to be cleaned, the device body 1 only needs to be pulled up to separate it from the water storage box 18. In this way, the liquid mixture inside the water storage box 18 can be poured out separately. This detachable and combinable method greatly facilitates the handling of the filtered liquid mixture by the staff, saving time and effort during operation.

[0028] A reinforcing plate 9 is embedded in the bottom of the pull rod 10, and an agitator plate 14 is fixedly connected to the bottom of the reinforcing plate 9. The agitator plate 14 is trapezoidal in shape. Since a reinforcing plate 9 is installed between the pull rod 10 and the agitator plate 14, the connection strength between the two can be improved.

[0029] The top of the fixed base 3 is provided with a sealing ring 4, and the Buchner funnel 5 is embedded inside the sealing ring. Since the fixed base 3 is provided with an additional sealing ring 4, the sealing between the two can be improved after the Buchner funnel 5 is installed, which has strong functionality.

[0030] The Buchner funnel 5 contains an ultrafiltration membrane 6, and the stirring plate 14 is suspended above the ultrafiltration membrane 6. The bottom of the Buchner funnel 5 is placed inside the fixed base 3. Since the Buchner funnel 5 is embedded inside the fixed base 3, it is convenient for the staff to install and disassemble the Buchner funnel 5.

[0031] The device body 1 has a connector 15 on its side, and a hose 16 is sleeved on the outside of the connector 15. The top of the base plate 2 has a vacuum pump 17, and the top of the vacuum pump 17 has a suction head, and the outside of the suction head is sleeved with a hose 16. Since the device body 1 and the vacuum pump 17 are integrated on the base plate 2, the structure is not overly complicated during use, and it is convenient for the staff to operate.

[0032] The working principle of the cleaning filtration device for silver powder production is as follows: When using this filtration device to clean silver powder, the device first needs to be assembled. First, the Buchner funnel 5 is embedded above the fixed base 3, and a sealing ring 4 is installed on the top of the fixed base 3. This ensures that when the Buchner funnel 5 is embedded inside the fixed base 3, the sealing ring 4 fits tightly against the outside of the Buchner funnel 5, achieving a tight seal. Then, the corresponding ultrafiltration membrane 6 is placed inside the Buchner funnel 5, and a certain amount of cleaning water is poured in to wet the ultrafiltration membrane 6. Next, the silver powder to be cleaned is poured into the Buchner funnel 5, and then... Add cleaning water again to moisten the silver powder and the dust adhering to its surface. Then, start the vacuum pump 17 to extract air. Since the vacuum pump 17 is connected to the device body 1 through the hose 16, a negative pressure, i.e., a pressure environment lower than atmospheric pressure, will be formed inside the device body 1. Under the action of negative pressure, the silver powder to be filtered and the dust on its surface will be sucked into the interior of the device body 1. At the same time, since the diameter of the silver powder is larger than the mesh diameter of the ultrafiltration membrane 6, the silver powder will remain on the ultrafiltration membrane 6. Water mixed with dust falls into the water storage box 18 inside the device body 1. This completes the cleaning and extraction of the silver powder. During the filtration process, if too much silver powder is poured in, resulting in poor filtration of the silver powder near the top layer, a stirring plate 14 is installed above the Buchner funnel 5. This stirring plate 14 is designed to be pulled up and down. It can be lowered and placed inside the silver powder mixture. Then, the rotating handle 13 is rotated at a constant speed, causing the pull rod 10 and the bottom stirring plate 14 to rotate, thus thoroughly stirring the accumulated silver powder. This allows the silver powder in the upper layer to change position and be fully mixed, facilitating the filtration process. The entire process requires no... The staff found an additional tool similar to a stirring rod to perform the stirring operation, which was quite convenient to use. After completing all the filtration work, when the staff cleaned the filtered liquid mixture, they only needed to pull the main body 1 of the device upward to separate it from the water storage box 18, and then pinch the water storage box 18 and the outer sealing frame 19 and pull it upward. In this way, the liquid mixture inside the water storage box 18 could be poured out separately. This detachable and combinable method greatly facilitated the staff in handling the filtered liquid mixture, saving time and effort during operation and making it highly practical.

[0033] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
