Description

Technical Field

[0001] This utility model relates to the field of silver paste storage technology, specifically to a nano silver paste storage device. Background Technology

[0002] Silver paste is a paste used to make silver electrodes. It is formulated from silver or its compounds, flux, binder, and diluent. According to the form in which silver exists, it can be divided into silver oxide paste, silver carbonate paste, and molecular silver paste; according to the silver firing temperature, it can be divided into high-temperature silver paste and low-temperature silver paste; according to the coating method, it can be divided into printing silver paste and spraying silver paste. During the processing using silver paste, it needs to be stored.

[0003] However, in actual use, silver paste is usually transported through pipelines during processing. When transporting through pipelines, the discharge port will be paused due to the replacement of storage tanks or containers. The pause in the processing and transportation of silver liquid is not convenient, and the frequent start and stop also leads to inconsistent processing. Therefore, when transporting silver liquid, a storage device that can be easily adjusted is needed to facilitate the temporary storage and discharge of silver liquid and ensure stable transportation. In addition, traditional storage devices are connected to external oxygen, which can easily lead to oxidation and other problems, affecting the normal storage of silver liquid. Utility Model Content

[0004] The purpose of this invention is to provide a nano silver paste storage device that solves the problems of existing devices that require convenient storage and discharge, and require isolation from oxygen to avoid oxidation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a nano silver paste storage device, comprising a tank, a connecting pipe and a lead screw, wherein the connecting pipe is fixedly connected through the center of the bottom end of the tank, a movable plate is slidably connected inside the tank, a lead screw is provided through one side inside the tank, and a rotating motor is installed on the top of the movable plate away from the lead screw on both sides.

[0006] The connecting pipe used for conveying is fitted with a conveying pipe at its top end, and a blocking net is installed at the top of the conveying pipe. The top of the blocking net is fixedly connected to the center of the bottom of the moving plate.

[0007] The lead screw used for rotation has a threaded ring connected to its outer wall, and the threaded ring is fixedly connected to the moving plate. A drive motor is fixedly connected to the bottom of the lead screw.

[0008] The movable plate used for lifting and adjusting has multiple condenser tubes arranged in a ring inside, and the bottom of the condenser tubes penetrates the interior of the movable plate and is connected to the bottom end.

[0009] Preferably, the top of the tank is closed, an air pipe is installed at the center of the top of the tank, and multiple support legs are fixedly installed around the bottom of the tank. The top of the air pipe is connected to an air pump through a conduit, and the air pump is connected to an inert gas storage tank.

[0010] Preferably, the interior of the movable plate is fixedly connected to the outer wall of the wire ring through each other, the top of the screw is rotatably connected to the top of the tank through a rotating shaft, and the bottom outer wall of the screw is rotatably connected to the bottom of the tank through a sealed bearing.

[0011] Preferably, the movable plate has a through hole corresponding to the wire ring inside, and the edge of the movable plate is tightly fitted to the inner wall of the tank by a rubber strip. The tank is cylindrical and hollow inside.

[0012] Preferably, the power output end at the bottom of the rotating motor is connected to a stirring impeller through the interior of the moving plate, and the outer wall of the stirring impeller is provided with multiple inclined blades arranged in a circumferential manner.

[0013] Preferably, the top of the condenser tube is electrically connected to an external power supply device via a cable, and the outer wall of the condenser tube is sleeved through the interior of the moving plate, with a through hole corresponding to the condenser tube inside the moving plate.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. The drive motor rotates, which in turn causes the lead screw to rotate and move the lead ring to the top. This causes the lead ring to move the moving plate upward, which in turn moves the delivery pipe to the top. This allows the delivery pipe to be pulled out from inside the connecting pipe, so that the top of the connecting pipe can be directly connected to the inside of the tank for easy silver liquid injection. When discharge is required, the moving plate can be moved to the bottom, causing the baffle to come into contact with the liquid. This allows the liquid to pass through the baffle and enter the delivery pipe, and then be discharged through the connecting pipe. This allows the tank to adjust the silver liquid in the transport pipeline without interrupting the silver liquid delivery inside the transport pipeline.

[0016] 2. The tank is equipped with a movable plate inside, which effectively prevents the top of the silver liquid from coming into contact with the air at the top of the tank. During use, inert gas can be easily injected into the top of the tank through the gas pipe, effectively expelling oxygen or other air and preventing the silver liquid from reacting with air and causing quality problems. At the same time, starting the rotating motor causes the stirring impeller to rotate, which effectively moves the silver liquid inside the tank, preventing stratification or long-term contact between the top and gas and causing reactions, thus maintaining the uniformity of the silver liquid.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figure 1-5 The device for storing nano-silver paste shown includes a tank 1, a connecting pipe 2, and a lead screw 3. The connecting pipe 2 is fixedly connected through the center of the bottom end of the tank 1. A movable plate 4 is slidably connected inside the tank 1. The lead screw 3 is installed through one side of the inside of the tank 1. Rotary motors 5 are installed on both sides of the top of the movable plate 4 away from the lead screw 3. A conveying pipe 201 is sleeved at the top of the connecting pipe 2 for conveying, and a blocking net 202 is provided at the top of the conveying pipe 201. The top of the blocking net 202 is fixedly connected to the center of the bottom of the movable plate 4. A threaded ring 301 is threaded to the outer wall of the lead screw 3 for rotation, and the threaded ring 301 is fixedly connected to the movable plate 4. A drive motor 302 is fixedly connected to the bottom of the lead screw 3. Multiple condensing pipes 401 are arranged in a circular pattern inside the movable plate 4 for lifting and adjustment. The bottom of the condensing pipes 401 penetrates the inside of the movable plate 4 and is connected to the bottom end.

[0027] like Figure 1 , Figure 2 As shown, the top of the tank 1 is closed, and an air pipe 101 is installed at the center of the top of the tank 1. Multiple support legs 102 are fixedly installed around the bottom of the tank 1. The top of the air pipe 101 is connected to an air pump through a conduit, and the air pump is connected to an inert gas storage tank. Inert gas is injected into the top of the tank 1 through the air pipe 101, thereby effectively expelling oxygen or other air and avoiding quality problems caused by the reaction between the silver liquid and air.

[0028] like Figure 3 , Figure 4 As shown, the interior of the movable plate 4 is fixedly connected to the outer wall of the wire ring 301 through a through-hole. The top of the screw 3 is rotatably connected to the top of the tank 1 through a rotating shaft. The bottom outer wall of the screw 3 is rotatably connected to the bottom of the tank 1 through a sealed bearing. The interior of the movable plate 4 has a through hole corresponding to the wire ring 301. The edge of the movable plate 4 is tightly fitted to the inner wall of the tank 1 through a rubber strip. The tank 1 is cylindrical and hollow inside. When the drive motor 302 is started to rotate, the screw 3 rotates and drives the wire ring 301 to move to the top. The wire ring 301 then drives the movable plate 4 to rise, which in turn drives the delivery pipe 201 to move to the top through the movable plate 4. This allows the delivery pipe 201 to be pulled out from the interior of the connecting pipe 2, so that the top of the connecting pipe 2 can be directly connected to the interior of the tank 1, facilitating the injection of silver liquid.

[0029] like Figure 4 , Figure 5 As shown, the power output end of the rotating motor 5 at the bottom passes through the interior of the moving plate 4 and is connected to the stirring impeller 501. The outer wall of the stirring impeller 501 is surrounded by multiple inclined blades. When the rotating motor 5 is started, the stirring impeller 501 rotates, which can effectively drive the silver liquid inside the tank 1 to move, avoiding the problem of layering or long-term contact between the top and the gas, thus maintaining the uniformity of the silver liquid.

[0030] like Figure 4 , Figure 5 As shown, the top of the condenser tube 401 is electrically connected to an external power supply via a cable, and the outer wall of the condenser tube 401 is connected to the interior of the movable plate 4 through a through hole. The movable plate 4 has a through hole corresponding to the condenser tube 401. Since the movable plate 4 is installed inside the tank 1, the top of the silver liquid can be effectively prevented from contacting the air at the top of the tank 1 through the blocking of the movable plate 4.

[0031] In use, the bottom of the connecting pipe 2 can be easily connected to the side wall of the transport pipe. When the outlet of the transport pipe is closed, the liquid silver can easily pass through the bottom connecting pipe 2 into the delivery pipe 201, and then through the baffle 202 at the top of the delivery pipe 201 into the interior of the tank 1. Simultaneously, because multiple condenser pipes 401 are installed around the inside of the moving plate 4, the liquid silver can be easily cooled. The drive motor 302 can also be easily started to rotate, causing the lead screw 3 to rotate and move the wire ring 301 to the top, thus allowing the wire ring 301 to move upwards. 1. The moving plate 4 is raised, which in turn moves the conveying pipe 201 to the top, thus pulling the conveying pipe 201 out from the inside of the connecting pipe 2. This allows the top of the connecting pipe 2 to be directly connected to the inside of the tank 1, facilitating the injection of silver liquid. When discharge is required, the moving plate 4 is moved to the bottom, causing the blocking net 202 to come into contact with the liquid. This allows the liquid to pass through the blocking net 202 into the conveying pipe 201 and then be discharged through the connecting pipe 2. This allows the tank 1 to adjust the silver liquid in the transport pipeline without interrupting the delivery of silver liquid inside the transport pipeline.

[0032] During use, the movable plate 4 inside the tank 1 effectively prevents the top of the silver liquid from contacting the air at the top of the tank 1. Simultaneously, inert gas can be easily injected into the top of the tank 1 through the gas pipe 101, effectively expelling oxygen or other air and preventing the silver liquid from reacting with air and causing quality problems. Furthermore, starting the rotating motor 5 causes the stirring impeller 501 to rotate, effectively moving the silver liquid inside the tank 1 and preventing stratification or long-term contact between the top and gas, thus maintaining the uniformity of the silver liquid.

[0033] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
