Description

Technical Field

[0001] This utility model relates to the field of battery separator technology, and in particular to a separator washing tank with a pipeline spray structure. Background Technology

[0002] The battery separator is a membrane material placed between the positive and negative electrodes of a battery. It is a very critical part of the battery and has a direct impact on battery safety and cost. Its main functions are to isolate the positive and negative electrodes and prevent electrons in the battery from passing through freely, while allowing ions in the electrolyte to pass freely between the positive and negative electrodes.

[0003] In current membrane manufacturing processes, dichloromethane is typically used to clean the membrane. According to existing Chinese utility model patent CN210995511U, a membrane washing system extraction tank and an extraction tank spray structure are described. The extraction tank spray structure includes a spray assembly and a circulation assembly disposed within the extraction tank. This spray structure allows for more thorough extraction of the lithium battery membrane within the extraction tank, improving production efficiency.

[0004] In the aforementioned structure, the spray pipe is positioned between the first and second rotating rollers, continuously spraying water onto the horizontal cross-section of the diaphragm between the rollers. However, the water flow in this structure impacts the middle of the diaphragm between the rollers, easily causing it to sway and deviate from its transport trajectory. Therefore, there is an urgent need to develop a diaphragm washing tank with a pipe spray structure to meet practical application requirements. Utility Model Content

A drain port is opened at the bottom of the tank body. The tank body also has a pipe spray structure. The pipe spray structure includes a spray pipe and a number of nozzles. The nozzles are arranged horizontally along the radial direction on one side of the first drive roller through the spray pipe. The nozzles are inclined towards the surface of the first drive roller.

[0007] As a further embodiment of the above description, the spray pipe is provided with several supports in the middle, and the spray pipe is fixedly connected to the inside of the feed inlet through the supports.

[0008] In the above description, as a further option, several nozzles are arranged in a linear array on the side wall of the spray pipe, the spray pipe is a hollow structure, and the nozzles and the spray pipe are connected.

[0009] As a further solution, as described above, a circulation component is provided between the spray pipe and the tank body, and the spray pipe forms a water circulation structure with the inner cavity of the tank body through the circulation component.

[0010] As a further embodiment of the above description, the circulation assembly includes a water pump, a filter, and a connecting hose.

Detailed Implementation

[0013] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0014] For this embodiment, please refer to Figures 1-5 The present invention relates to a diaphragm washing tank with a pipeline spray structure, comprising a tank body 1, wherein the interior of the tank body 1 is an inner cavity 11 for conducting diaphragm material, and an outlet 2 and an inlet 3 are respectively opened on both ends of the tank body 1. A rotatable first transmission roller 41 is provided on the side of the inner cavity 11 near the outlet 2 and the inlet 3, and a rotatable second transmission roller 42 is provided at the bottom of the inner cavity 11. A drain outlet 5 is opened at the bottom of the tank body 1. The tank body 1 also has a pipeline spray structure, which includes a spray pipe 6 and a plurality of nozzles 61. The nozzles 61 are arranged horizontally along the radial direction on one side of the first transmission roller 41 through the spray pipe 6, and the nozzles 61 are inclined toward the surface of the first transmission roller 41.

[0015] Several nozzles 61 are arranged radially and horizontally on one side of the first drive roller 41 through the spray pipe 6. The nozzles 61 are inclined towards the surface of the first drive roller 41, so that the spray direction of the nozzles 61 can be concentrated on the surface of the first drive roller 41. This can effectively transmit the impact force of the water flow to the first drive roller 41, avoid the water flow impacting the diaphragm and causing shaking, and ensure the stability of the diaphragm transportation.

[0016] Specifically, such as Figure 2-3 As shown, a number of nozzles 61 are arranged in a linear array on the side wall of the spray pipe 6. The spray pipe 6 is a hollow structure, and the nozzles 61 are connected to the spray pipe 6. A circulation component 9 is also provided between the spray pipe 6 and the tank body 1. The spray pipe 6 forms a water circulation structure with the inner cavity 11 inside the tank body 1 through the circulation component 9.

[0017] Specifically, such as Figure 5 As shown, the spray pipe 6 has several supports 8 in the middle. The spray pipe 6 is fixedly connected to the inside of the feed inlet 3 through the supports 8. The nozzle 61 is inclined toward the first transmission roller 41 on the side close to the feed inlet 3.

[0018] Specifically, such as Figure 1 As shown, the circulation component 9 includes a water pump 91, a filter 92, and a connecting hose 93. One end of the water pump 91 is connected to the inner cavity 11 of the tank body 1, and one end of the water pump 91 is connected to the filter 92. One end of the connecting hose 93 is connected to the filter 92, and the other end of the connecting hose 93 extends to the top of the tank body 1 and is connected to the spray pipe 6.

[0019] The working process of a diaphragm washing tank with a pipe spray structure is as follows: One end of the diaphragm is alternately wrapped around the first drive roller 41 and the second drive roller 42 from the inlet 3. Then, the diaphragm is pulled out from one side of the inlet 3 and placed inside the inner cavity 11 of the tank body 1 with dichloromethane, so that the dichloromethane covers the second drive roller 42. The diaphragm is moved by continuously rotating the first drive roller 41 and the second drive roller 42. At this time, the dichloromethane inside the inner cavity 11 is injected into the spray pipe 6 through the filter 92 and the connecting hose 93 by the water pump 91. Then, the dichloromethane is washed on the diaphragm on the surface of the first drive roller 41 by the nozzles 61 arranged in a linear array.

[0020] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
