Description

Technical Field

[0001] The utility model relates to the technical field of pipeline cleaning, in particular to a ball-receiving and ball-transmitting integrated device for a slurry conveying system. Background Art

[0002] With the rapid development of new energy, lithium-ion batteries are increasingly widely used. During the processing of lithium-ion batteries, the slurry generated during the processing needs to be transported. During the slurry transportation process, due to the slurry sedimentation characteristics, material is prone to accumulation in the pipeline, and it is necessary to regularly clean the pipeline to ensure the smooth transportation of the slurry. Because the pipeline is closed and the transportation distance is long, for the convenience of cleaning, the slurry transportation system is often equipped with a cleaning system. At present, the cleaning operation of the pipeline is basically achieved through cleaning balls.

[0003] The slurry ball pushing device is an important part of the slurry conveying system in the slurry making section. The design of its function needs to consider the influence of multiple factors. In the prior art, the ball pushing device of the slurry conveying system usually has only one direction of pushing the ball. The staff in the mixing workshop inserts the cleaning ball into the slurry pipeline. After pushing the ball, they need to go to the farthest end of the pipeline in the coating workshop to get the ball, which is very inconvenient and increases the labor. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the utility model provides an integrated ball-transmitting and receiving device for a slurry conveying system, which can push the ball to the farthest part of the pipeline and does not require going to the farthest part of the pipeline to retrieve the ball.

The ball plugging tool is arranged at the pipe mouth of the slurry conveying pipeline, and is used to push a pipe cleaning ball into the pipeline. A first ball sensor is arranged between the ball plugging tool and the first branch; an air intake assembly and a pressure detection assembly are arranged on the first branch to provide compressed air to push the pipe cleaning ball and detect the pipeline pressure; the first ball valve is arranged in the slurry conveying pipeline to control the on-off of the pipeline; a liquid collecting assembly is arranged on the second branch, and the liquid collecting assembly comprises a liquid collecting trolley for receiving residual slurry.

[0007] As a further implementation, the ball plugging tool is a cylindrical structure, which is coaxially arranged in the slurry conveying pipeline and fixedly connected to the slurry conveying pipeline, and is used to push the cleaning ball into the slurry conveying pipeline.

[0008] As a further implementation method, the ball plugging fixture and the slurry conveying pipeline are fixed by a clamp, which is a detachable connection.

[0009] As a further implementation method, the air intake assembly includes a connected air intake pipe and a second ball valve, which can generate compressed air to enter the slurry conveying pipeline as power to push the cleaning ball forward in the pipeline; the second ball valve is close to the slurry conveying pipeline and is used to control the on and off of the air intake of the first branch.

[0010] As a further implementation, a pressure regulating valve is provided between the second ball valve and the intake pipe to control the intake pressure of the first branch.

[0011] As a further implementation, the air inlet pipe includes an air source, and the air source is an air compressor.

[0012] As a further implementation method, the pressure detection component is arranged between the slurry conveying pipeline and the second ball valve, and includes a mechanical pressure gauge and a pressure transmitter. The mechanical pressure gauge and the pressure transmitter are respectively installed on both sides of the first branch and connected to the first branch, so as to detect the pressure in the first branch that pushes the cleaning ball.

[0013] As a further implementation, a second ball sensor is provided in the slurry conveying pipeline between the first ball valve and the second branch, for detecting whether the cleaning ball has passed the liquid collecting component during the ball collecting stage.

[0014] As a further implementation, the liquid collecting component further includes a third ball valve, and the third ball valve is located between the liquid collecting trolley and the slurry conveying pipeline on the second branch to control the on-off of the second branch.

[0015] As a further implementation method, a liquid level sensor is provided in the liquid collecting trolley, and when the waste liquid in the trolley reaches a certain height, the waste liquid is discharged.

[0016] By adopting the above technical solution, the beneficial effects of the utility model are as follows:

[0017] 1. The utility model can realize the functions of launching and collecting balls and automatically switching the states of launching and collecting balls at the two end pipe openings of the slurry conveying pipeline through the structures of the ball plugging tool, ball sensor, ball valve and air intake assembly, so that the cleaning ball at the end of the pipeline can be returned to the launching end, saving the work of going to the end of the pipeline to get the ball and going back and forth, effectively reducing the labor intensity of manual labor and improving the production efficiency of the pulping section.

It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the utility model. Unless otherwise specified, all technical and scientific terms used in the utility model have the same meanings as those commonly understood by ordinary technicians in the technical field to which the utility model belongs. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0029] Embodiment 1

[0030] In a typical embodiment of the present application, a ball-receiving and ball-transmitting integrated device for a slurry conveying system is provided, which is arranged at the starting point and the end point of a slurry conveying pipeline, such as Figure 1-4As shown, it includes a ball plugging tool 10, a first branch, a first ball valve 50 and a second branch which are sequentially arranged along the slurry conveying pipeline. The ball plugging tool 10 is arranged at the pipeline mouth and is used to plug a pipe cleaning ball into the pipeline. A first ball sensor 20 is arranged in the ball plugging tool; an air intake assembly and a pressure detection assembly are arranged on the first branch to provide compressed air to push the pipe cleaning ball and ensure the safety of pipeline pressure; the first ball valve is arranged in the slurry conveying pipeline to control the on-off of the pipeline; a liquid collecting assembly is arranged on the second branch, and the liquid collecting assembly includes a liquid collecting trolley 702 which can receive residual slurry.

[0031] like Figure 1 As shown, the ball plugging tool 10 is a cylindrical structure, which is coaxially arranged in the slurry conveying pipeline to push the pipe cleaning ball into the slurry conveying pipeline and block the pipe opening. In order to facilitate insertion into the pipeline, the front end of the ball plugging tool is designed to be conical, and the end structure has a cup mouth, which can be fixed to the pipe cup mouth by a clamp to form a detachable connection, so as to facilitate the removal or insertion of the pipe cleaning ball. The length of the ball plugging tool is set to at least allow the pipe cleaning ball to be pushed to the first ball sensor 20.

[0032] like Figure 2 As shown, the air intake assembly 30 includes a second ball valve 303, a pressure regulating valve 302 and an air intake pipe 301 connected in sequence on the first branch. The second ball valve 303 is close to the slurry conveying pipeline and can generate compressed air to enter the slurry conveying pipeline as a power to push the cleaning ball forward in the pipeline. Among them, the air intake pipe 301 includes an air source, which can provide compressed air as a power. The air source can use an existing air compressor on the market. The pressure regulating valve 302 controls the size of the air intake pressure of the first branch to the slurry conveying pipeline, and the second ball valve 303 controls the on-off of the air pressure of the first branch.

[0033] like Figure 1 , 3 As shown, the pressure detection component 40 is arranged between the slurry conveying pipeline and the second ball valve 303, and includes a mechanical pressure gauge 401 and a pressure transmitter 402. The mechanical pressure gauge 401 and the pressure transmitter 402 are respectively installed on both sides of the first branch and connected to the first branch, so as to detect the pressure in the slurry conveying pipeline.

[0034] A second ball sensor 60 is provided in the slurry conveying pipeline between the first ball valve 50 and the second branch, and is used to detect whether the cleaning ball has passed the liquid collecting component during the ball collecting stage.

[0035] like Figure 4 As shown, the liquid collecting assembly 70 also includes a third ball valve 701, which is arranged on the second branch between the liquid collecting trolley 702 and the slurry conveying pipeline, and is used to control the on-off of the second branch. A liquid level sensor is provided in the liquid collecting trolley. When the waste liquid in the trolley reaches a certain height, the waste liquid in the trolley can be discharged by its own gravity, and then the cleaning operation can continue.

[0036] Among them, the ball plugging tool 10, the first ball sensor 20, the air intake assembly 30 and the pressure detection assembly 40 play a role in serving the ball. When the cleaning ball reaches the first ball sensor, the air intake assembly provides the power to push the cleaning ball to move, and the pressure detection assembly detects the air pressure of the first branch to ensure that the pipeline pressure is normal and safe.

[0037] The first ball valve 50, the second ball sensor 60 and the liquid collecting assembly 70 play the role of detection and discharge in the ball collecting stage. When the cleaning ball has not reached the second ball sensor, the first ball valve 50 remains closed and the third ball valve 701 remains open, which plays the role of discharging pressure and preventing pipeline pressure from leaking.

[0038] The first ball valve 50, the first ball sensor 20 and the ball plugging tool 10 cooperate to transform the ball receiving stage into the ball serving stage. When the cleaning ball reaches the second ball sensor 60, the third ball valve 701 is closed, the first ball valve 50 is opened, and the cleaning ball continues to move forward and reaches the first ball sensor 20, completing the transformation from the ball receiving state to the ball serving state.

[0039] The working process of this embodiment is:

[0040] At the starting point and the end point of the slurry conveying pipeline, the ball-receiving and ball-transmitting integrated devices of this embodiment are arranged respectively, such as Figure 1-4 As shown, in the ball-launching stage, the integrated ball-receiving and -launching device at the starting point of the pipeline uses the ball-plugging tool 10 to insert the pipe cleaning ball into the slurry conveying pipeline. When the first ball sensor 20 detects that the ball is in place, the second ball valve 303 is opened, the first branch is connected to the slurry conveying pipeline, and the air intake component 30 provides compressed air as a power to push the pipe cleaning ball forward; at the same time, the first ball valve 50 is opened to allow the pipe cleaning ball to pass through; the third ball valve 701 is closed, the second branch is blocked, and the pipe cleaning ball pushes the residual slurry in the pipe to move to the end of the pipeline.

[0041] The integrated ball-transmitting and receiving device at the end of the pipeline is in the ball-receiving stage. In the ball-receiving stage, the first ball valve 50 is closed and the third ball valve 701 is opened, so that the slurry can flow into the liquid-receiving trolley. When the pipe cleaning ball is pushed forward by the compressed air and the second ball sensor 60 senses that the pipe cleaning ball is in place, the first ball valve 50 is opened, and the pipe cleaning ball moves forward to the first ball sensor 20; at this time, the second ball valve 303 is closed, and the first branch is blocked. Close the air intake assembly at the rear end of the pipe cleaning ball, that is, at the starting point of the pipeline, and stop the movement of the pipe cleaning ball before the ball plugging tooling, and the ball collection is completed. According to needs, the integrated ball-transmitting and receiving device at the end of the pipeline can enter the ball-pushing stage again at this time, and push the ball in the opposite direction to the integrated ball-transmitting and receiving device at the starting point of the pipeline for pipe cleaning, realizing two-way ball-pushing pipe cleaning. After each ball-pushing, there is no need to go to the end of the pipeline to get the ball, which greatly reduces the labor intensity and improves the production efficiency of the pulping section.

[0042] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
