Description

Technical Field

[0001] This utility model relates to pipe connection, and more particularly to an automatic clamping liquid conveying pipe connection structure. Background Technology

[0002] In the actual production process of lithium batteries, one step involves mixing asphalt and graphite powder to improve battery performance. Since the mixing tanks contain graphite powder, the liquid asphalt simply needs to be delivered to each tank. Currently, this is achieved by controlling a transport trolley to move the liquid asphalt-containing storage tanks along the production line and sequentially delivering the liquid asphalt to the mixing tanks via pipelines. However, when the storage tanks are supplying liquid asphalt to the mixing tanks, they need to be replenished periodically from the asphalt storage tank. Currently, replenishing the storage tanks and asphalt storage tanks typically involves manually screwing the discharge pipe from the asphalt storage tank onto the storage tank. This process requires manual control and fixation, resulting in low connection efficiency and significant time and labor costs. Furthermore, manually controlling the connection tightness makes it difficult to avoid loose connections, which can affect the stability and safety of the liquid asphalt delivery process. Utility Model Content

[0003] This utility model provides an automatically clamping liquid conveying pipeline docking structure, which solves the technical problems of low connection efficiency, high cost, poor stability and safety during liquid asphalt transportation, and provides the following technical solution:

[0004] An automatically tightening liquid conveying pipeline docking structure includes a connecting pipe and a connecting seat. The upper end of the connecting pipe is used to connect to a feed pipe. The connecting seat is hollow inside, and the bottom of the connecting seat is used to connect to a feeding pipe. A sealing plate is fixedly installed on the outer periphery of the lower end of the connecting pipe. The outer diameter of the connecting pipe corresponding to the bottom of the sealing plate is smaller than the diameter of the hollow part of the connecting seat, and the outer diameter of the sealing plate is larger than the diameter of the hollow part of the connecting seat. A first driving mechanism is connected to the connecting pipe to drive the feed pipe and the connecting pipe to move downward, so that the connecting pipe is inserted into the connecting seat. The characteristic is that the connecting seat... A first flange is concentrically fixed to the outer periphery of the top. Multiple fixing plates are fixedly installed on the top of the sealing plate. The multiple fixing plates are evenly distributed along the circumference of the connecting pipe. A second driving mechanism is fixedly installed on one side of the top of each fixing plate. Each second driving mechanism is linked to a movable claw. Each movable claw is hook-shaped. The side of each movable claw near the sealing plate is hinged to the fixing plate. When the connecting pipe is inserted into the connecting seat, each second driving mechanism is used to drive the corresponding movable claw to rotate, so that the hook part of each movable claw abuts against the bottom of the first flange.

[0005] By adopting the above technical solution, and through the setting of the movable claw, when the connecting pipe is inserted into the connecting seat, the movable claw is driven by the second drive mechanism to rotate along the hinge until the bottom end of the movable claw abuts against the bottom of the first flange. At this time, the first flange is locked in the notch at the hook of the movable claw, thereby completing the fixation of the connecting pipe and the connecting seat. The structure is simple and can realize automated connection operation, which will improve connection efficiency and reduce labor costs. In addition, after automated connection, automated clamping operation can also be realized, and the tightness of the connection can be remotely controlled, thereby preventing the connection between the connecting pipe and the connecting seat from loosening. This will greatly reduce the risk of leakage and failure, thus ensuring the connection stability of the connecting pipe and the connecting seat and the safety of liquid asphalt transmission.

[0006] Furthermore, the top of the first flange has a sealing ring arranged in an annular shape, the inner diameter of which is larger than the outer diameter of the sealing plate, and a sealing strip pressure ring is fixedly arranged on the top of the sealing ring, the inner diameter of which is smaller than the outer diameter of the sealing plate.

[0007] By adopting the above technical solution, and through the setting of the sealing ring, after the connecting pipe is inserted into the connecting seat and the connecting pipe and the connecting seat are fixed, the sealing plate presses on the top of the sealing ring. This can ensure that no liquid asphalt will seep out from the connecting seat during the liquid asphalt transmission process, thereby improving the sealing performance of the device and thus improving the safety of the liquid asphalt transmission process.

[0008] Furthermore, the top outer periphery of the connecting pipe has a second flange that is concentrically fixed, and the bottom outer periphery of the feeding pipe has a third flange that is concentrically fixed. A pneumatic clamp butterfly valve is provided between the second flange and the third flange, wherein the top and bottom of the pneumatic clamp butterfly valve are concentrically arranged with the third flange and the second flange, respectively. The second flange has a plurality of vertically arranged first connecting rods, which are arranged sequentially along the circumference of the second flange, and the other end of each first connecting rod passes through the third flange.

[0009] By adopting the above technical solution and setting up a pneumatic wafer butterfly valve, the flow rate of the fluid medium can be precisely adjusted by controlling its opening degree, thereby ensuring the stability and reliability of the liquid asphalt transmission process. Moreover, the pneumatic wafer butterfly valve has a simple structure, which makes its installation and maintenance relatively easy, thereby reducing cost investment.

[0010] Furthermore, the bottom outer periphery of the connecting seat has a fourth flange that is concentrically fixed, and the top outer periphery of the feeding pipe has a fifth flange that is concentrically fixed. An electric wafer butterfly valve is provided between the fourth and fifth flanges, with the top and bottom of the butterfly valve being concentrically arranged with the fourth and fifth flanges, respectively. The fifth flange has a plurality of vertically arranged second connecting rods, which are arranged sequentially along the circumference of the fifth flange, and the other end of each second connecting rod passes through the fourth flange.

[0011] By adopting the above technical solution and setting up an electric wafer butterfly valve, the liquid asphalt transmission process can be quickly cut off when the storage tank is full, thus preventing liquid asphalt leakage and ensuring the safety of liquid asphalt transportation.

[0012] Furthermore, the first driving mechanism includes a first cylinder, the output shaft of the first cylinder is fixedly provided with a first push plate, and the first push plate is a straight plate; the top of the third flange is provided with a support plate, the top of the support plate is fixedly provided with a second push plate, and the second push plate is arranged in an "L" shape. The lower end of the vertical section of the second push plate is provided with a notch that is consistent with the shape of the outer periphery of the feed pipe, so that the vertical section of the second push plate abuts against the feed pipe, and the horizontal sections of the first push plate and the second push plate are fixedly connected.

[0013] Furthermore, the second drive mechanism includes a second cylinder, and a connecting member is fixedly provided on the output shaft of the second cylinder. The lower end of the connecting member is provided with a notch, so that the lower end of the connecting member is forked. The movable claw is hinged in the fork of the connecting member.

[0014] Furthermore, the outer diameter of the connecting pipe below the sealing plate decreases sequentially from top to bottom, so that the lower end of the connecting pipe below the sealing plate is set in a frustum shape.

[0015] In summary, this application has the following beneficial effects:

[0016] 1. With the movable claw, after the connecting pipe is inserted into the connecting seat, the second drive mechanism drives the movable claw to rotate along the hinge until the bottom of the movable claw abuts against the bottom of the first flange. At this time, the first flange is locked in the notch at the hook of the movable claw, thus completing the fixation of the connecting pipe and the connecting seat. The structure is simple and can realize automated connection operation, which will improve connection efficiency and reduce labor costs. In addition, after automated connection, automated clamping operation can be realized, and the tightness of the connection can be remotely controlled, thereby avoiding loosening of the connection between the connecting pipe and the connecting seat. This will greatly reduce the risk of leakage and failure, thus ensuring the connection stability of the connecting pipe and the connecting seat and the safety of liquid asphalt transmission.

[0017] 2. By setting the sealing ring, after the connecting pipe is inserted into the connecting seat and the connecting pipe and the connecting seat are fixed, the sealing plate presses on the top of the sealing ring. This can ensure that no liquid asphalt will seep out from the connecting seat during the liquid asphalt transfer process, thereby improving the sealing performance of the device and thus improving the safety of the liquid asphalt transfer process.

[0018] 3. By setting up a pneumatic wafer butterfly valve, the flow rate of the fluid medium can be precisely adjusted by controlling its opening degree, thereby ensuring the stability and reliability of the liquid asphalt transmission process. In addition, the pneumatic wafer butterfly valve has a simple structure, which makes the installation and maintenance of the pneumatic wafer butterfly valve relatively easy, thereby reducing cost investment.

[0019] 4. By using an electric wafer butterfly valve, which has high control precision and fast response speed, the liquid asphalt transmission process can be quickly cut off when the storage tank is full, thus preventing liquid asphalt leakage and ensuring the safety of liquid asphalt transportation.

Detailed Implementation

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] In a specific embodiment, reference is made to... Figure 1-4 An automatic pressing liquid conveying pipeline docking structure includes a connecting pipe 1 and a connecting seat 2. The connecting pipe 1 is installed on an asphalt storage tank, and the connecting seat 2 is installed on a dispensing storage tank. The upper end of the connecting pipe 1 is connected to a feed pipe 3. The connecting seat 2 is hollow inside, and the bottom of the connecting seat 2 is connected to a feeding pipe 4. The feeding pipe 4 is connected to the inside of the storage tank. Liquid asphalt is conveyed to the storage tank after passing through the feed pipe 3, connecting pipe 1, connecting seat 2, and feeding pipe 4. A sealing plate 5 is fixedly installed on the outer periphery of the lower end of the connecting pipe 1. The outer diameter of the connecting pipe 1 below the sealing plate 5 is smaller than the diameter of the hollow part of the connecting seat 2, and the outer diameter of the sealing plate 5 is larger than the diameter of the hollow part of the connecting seat 2. The outer diameter of the connecting pipe 1 below the sealing plate 5 decreases from top to bottom, so that the lower end of the connecting pipe 1 below the sealing plate 5 forms a frustum. The connecting pipe 1 is configured such that a first driving mechanism 6 is connected to the connecting pipe 1, which drives the feed pipe 3 and the connecting pipe 1 to move downward, so that the connecting pipe 1 is inserted into the connecting seat 2. A first flange 7 is concentrically fixed on the outer periphery of the top of the connecting seat 2. Multiple fixing plates 8 are fixedly installed on the top of the sealing plate 5. The multiple fixing plates 8 are evenly distributed along the circumference of the connecting pipe 1. A second driving mechanism 9 is fixedly installed on one side of the top of each fixing plate 8. Each second driving mechanism 9 is linked to a movable claw 10. Each movable claw 10 is hook-shaped. The side end of each movable claw 10 near the sealing plate 5 is hinged to the fixing plate 8. When the connecting pipe 1 is inserted into the connecting seat 2, each second driving mechanism 9 is used to drive the corresponding movable claw 10 to rotate, so that the hook part of each movable claw 10 abuts against the bottom of the first flange 7.

[0028] After the connecting pipe 1 is inserted into the connecting seat 2, the second drive mechanism 9 drives the movable claw 10 to rotate along the hinge until the bottom end of the movable claw 10 abuts against the bottom of the first flange 7. At this time, the first flange 7 is locked in the notch at the hook of the movable claw 10, thus completing the fixation of the connecting pipe 1 and the connecting seat 2. The structure is simple and can realize automated connection operation, which will improve connection efficiency and reduce labor costs. After automated connection, automated clamping operation can also be realized, and the tightness of the connection can be remotely controlled, thereby avoiding loosening of the connection between the connecting pipe 1 and the connecting seat 2. This will greatly reduce the risk of leakage and failure, thus ensuring the connection stability of the connecting pipe 1 and the connecting seat 2 and the safety of liquid asphalt transmission.

[0029] The top of the first flange 7 has a ring-shaped sealing ring 11. The inner diameter of the sealing ring 11 is larger than the outer diameter of the sealing plate 5. A sealing strip pressure ring 12 is fixedly installed on the top of the sealing ring 11. The inner diameter of the sealing strip pressure ring 12 is smaller than the outer diameter of the sealing plate 5. After the connecting pipe 1 is inserted into the connecting seat 2 and the connecting pipe 1 and the connecting seat 2 are fixed, the sealing plate 5 presses on the top of the sealing ring 11. This ensures that no liquid asphalt will seep out from the connecting seat 2 during the liquid asphalt transfer process, thereby improving the sealing performance of the device and improving the safety of the liquid asphalt transfer process.

[0030] The top outer periphery of the connecting pipe 1 has a second flange 13 that is concentrically fixed, and the bottom outer periphery of the feeding pipe 4 has a third flange 14 that is concentrically fixed. A pneumatic wafer butterfly valve 15 is provided between the second flange 13 and the third flange 14. The top and bottom of the pneumatic wafer butterfly valve 15 are concentrically arranged with the third flange 14 and the second flange 13, respectively. The second flange 13 has multiple vertically arranged first connecting rods 16, which are arranged sequentially along the circumference of the second flange 13, and the other end of each first connecting rod 16 passes through the third flange 14. The flow rate of the fluid medium can be precisely adjusted by controlling the opening degree of the pneumatic wafer butterfly valve 15, thereby ensuring the stability and reliability of the liquid asphalt transmission process. Moreover, the pneumatic wafer butterfly valve 15 has a simple structure, which makes the installation and maintenance of the pneumatic wafer butterfly valve 15 relatively easy, thereby reducing the cost.

[0031] The bottom outer periphery of the connecting seat 2 has a fourth flange 17 that is concentrically fixed, and the top outer periphery of the feeding pipe 4 has a fifth flange 18 that is concentrically fixed. An electric wafer butterfly valve 19 is provided between the fourth flange 17 and the fifth flange 18. The top and bottom of the butterfly valve 19 are concentrically arranged with the fourth flange 17 and the fifth flange 18, respectively. There are multiple vertically arranged second connecting rods 20 on the fifth flange 18. The multiple second connecting rods 20 are arranged sequentially along the circumference of the fifth flange 18, and the other end of each second connecting rod 20 passes through the fourth flange 17. Because the electric wafer butterfly valve 19 has high control precision and fast response speed, it can quickly cut off the liquid asphalt transmission process when the liquid asphalt in the storage tank is full, avoiding liquid asphalt leakage and thus ensuring the safety of liquid asphalt transportation.

[0032] The first drive mechanism 6 includes a first cylinder, the output shaft of which is fixedly provided with a first push plate 21, and the first push plate 21 is a straight plate; the top of the third flange 14 is provided with a support plate 22, the top of which is fixedly provided with a support plate 23, and the support plate 23 is "L" shaped. The lower end of the vertical section of the support plate 23 is provided with a notch that is consistent with the shape of the outer periphery of the feed pipe 3, so that the vertical section of the support plate 23 abuts against the feed pipe 3, and the first push plate 21 and the horizontal section of the support plate 23 are fixedly connected.

[0033] The second drive mechanism 9 includes a second cylinder. The output shaft of the second cylinder is fixedly provided with a connector 24. The lower end of the connector 24 is provided with a notch, so that the lower end of the connector 24 is forked. The movable claw 10 is hinged in the fork of the connector 24. It is common knowledge to set a controller and connect the controller to the pneumatic clamp butterfly valve 15, the electric clamp butterfly valve 19, the first cylinder, and multiple second cylinders respectively, and then remotely control them through the controller. It will not be elaborated here.

[0034] Operation process: The trolley carrying the dispensing storage tank is moved to the location of the asphalt storage tank. At this time, the connecting pipe 1 is above the connecting seat 2, and the second cylinder is in the closed rotating state. When the dispensing storage tank needs to be replenished with liquid asphalt, the first cylinder is started and drives the first push plate 21 to move downward. Then, the first push plate 21 drives the second push plate 23 to move downward. The second push plate 23 presses the feed pipe 3 and the connecting pipe 4 downward. When the lower end of the connecting pipe 4 is pushed into the connecting seat 2, the first cylinder stops, and the automated connection work is completed. The second cylinder is started and drives the connecting piece 24 to move downward. Since the lower end of the connecting piece 24 is hinged to the upper end of the movable claw 10 and the side end near the fixed plate 8 is also hinged, the movable claw 10 will rotate along the hinge point of the side end during the process of the second cylinder driving the connecting piece 24 downward until the hook at the bottom of the movable claw 10 touches the bottom of the first flange 7. At this time, the automated fixing work of the connecting pipe 1 and the connecting seat 2 is completed, and the liquid asphalt transfer work can begin.
