Description

Technical Field

[0001] The utility model relates to the technical field of cleaning liquid injection nozzles, in particular to a liquid injection nozzle cleaning tool and a cleaning system. Background Art

[0002] The battery needs to be formed in the high temperature negative pressure formation workshop. The formation of lithium batteries is the first charging of lithium batteries after they are produced to activate the batteries. Its function is similar to the "formatting" of floppy disks. The battery can only start normal charging and discharging after the formation is completed. The principle is to charge the battery for the first time to activate the active substances in the battery and generate a dense SEI film on the surface of the anode (negative electrode) to protect the stability of the entire chemical interface.

[0003] Gas will continue to be generated during the battery formation process, and the gas will lift the electrolyte in the battery into the formation negative pressure cup. When the formation is completed, the electrolyte in the negative pressure cup will flow back into the battery. However, due to some blocked vacuum channels, the electrolyte cannot flow back completely. The electrolyte remaining in the negative pressure cup will quickly weather and crystallize. The electrolyte crystals will block the negative pressure extraction channel of the battery, affecting the next use of negative pressure formation.

[0004] The cleaning tool currently used to clean the formation negative pressure cup includes a liquid storage tank, a micro pump, a solenoid valve, a flow divider, and a joint connected to the negative pressure nozzle. When cleaning, the injection nozzle is first lowered into the cleaning cavity of the cleaning mechanism, and then DMC solvent (dimethyl carbonate solvent) is injected into the cleaning mechanism. Then, nitrogen is blown in, and the DMC solvent is sprayed in a fountain shape by nitrogen to clean the injection nozzle.

[0005] The above cleaning method can remove the electrolyte remaining around the injection nozzle to a certain extent. However, some electrolyte crystals around the injection nozzle will be in a free floating state. The free floating electrolyte crystals are easily adsorbed on the surface of the injection nozzle and cannot be completely cleaned. As time goes by, the free floating objects will continue to crystallize. When the injection nozzle is used to inject electrolyte later, there is a risk that the crystals attached to the injection nozzle will fall into the injection hole of the battery.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0036] The following is a further detailed description of an embodiment of a liquid injection nozzle cleaning tool and system of the utility model in conjunction with the accompanying drawings.

[0037] On the one hand, if Figure 1 As shown, the present application provides a liquid injection nozzle cleaning tool, including a cleaning container 1, in which the liquid injection nozzle 3 is cleaned, and the inner wall and the outer wall of the liquid injection nozzle 3 can be cleaned simultaneously during cleaning, thereby achieving complete cleaning and solving the problem of incomplete cleaning of the crystallization on the surface of the liquid injection nozzle in the prior art.

[0038] Specifically, a accommodating space is provided in the cleaning container 1 for placing the liquid injection nozzle 3. The cleaning container 1 is provided with a cleaning liquid inlet 11 and a cleaning liquid outlet 12 which are connected to the above-mentioned accommodating space. A baffle plate 121 is provided in the above-mentioned accommodating space. When the above-mentioned liquid injection nozzle 3 is placed in the above-mentioned accommodating space, the cleaning liquid can enter the liquid injection port of the liquid injection nozzle 3 through the above-mentioned baffle plate 121.

[0039] It can be understood that when the cleaning liquid flows into the containing space from the cleaning liquid inlet 11, it can enter the liquid injection port of the liquid injection nozzle 3 through the guidance of the baffle 121. At the same time, when the cleaning liquid enters the containing space, it can also simultaneously clean the outside of the liquid injection nozzle 3.

[0040] In this example, the baffle plate 121 is provided on the peripheral side of the cleaning liquid outlet 12. When the liquid injection nozzle 3 is placed in the accommodating space, the liquid injection mask of the liquid injection nozzle 3 is provided on the outer side of the baffle plate 121 and there is a gap between the baffle plate 121 and the baffle plate 121, thereby forming a channel for the cleaning liquid to flow from the cleaning liquid inlet 11 into the accommodating space and then flow out from the cleaning liquid outlet 12.

[0041] That is, when the liquid injection nozzle 3 is placed in the accommodation space, its liquid injection housing is arranged on the outside of the baffle plate 121, overlaps with part of the baffle plate 121 and has a gap for the cleaning liquid to flow, and there is also a gap between the liquid injection port and the inner wall of the cleaning container 1, thereby forming a channel for the cleaning liquid to flow from the cleaning liquid inlet 11 into the accommodation space and then flow out from the cleaning liquid outlet 12. During cleaning, the cleaning liquid flows from the cleaning liquid inlet 11 into the accommodation space, and cleans the outer wall and the inner wall of the liquid injection nozzle 3 simultaneously during the process of flowing through the channel.

[0042] It can be understood that the cleaning liquid has a certain flow rate when entering the containing space, and the inner wall and outer wall of the injection nozzle 3 are cleaned by the flow of the cleaning liquid in the channel. Since the baffle 121 is provided, the cleaning liquid can change the flow direction at the baffle. When the flow rate of the cleaning liquid is large enough, the cleaning liquid with changed flow direction flushes the inner wall of the injection nozzle 3.

[0043] In some optional embodiments, such as Figure 2 As shown, the cleaning container 1 includes an annular side wall 13, a cover body 14 and a bottom wall 15; the cover body 14 is covered on the annular side wall 13, the cleaning liquid inlet 11 is opened on the cover body 14, and a limiting hole for placing the liquid injection nozzle 3 is provided on the cover body 14; the bottom wall 15 is connected to the side of the annular side wall 13 away from the cover body 14, the center of the bottom wall 15 protrudes in the direction away from the cover body 14, and the cleaning liquid outlet 12 is opened at the center of the bottom wall 15.

[0044] It can be understood that the annular side wall 13, the cover body 14 and the bottom wall 15 form the above-mentioned accommodation space, and the cleaning liquid outlet 12 is located at the bottom of the accommodation space, so that the cleaning liquid can be collected at the groove formed between the annular side wall 13 and the baffle 121, so as to soak the liquid outlet of the injection nozzle 3. In this way, the electrolyte crystals attached to the injection nozzle 3 can be cleaned more effectively. The baffle 121 and the bottom wall 15 form an acute angle, the purpose of which is to make the cleaning liquid gather at the baffle 121 as much as possible, saving the amount of cleaning liquid. At the same time, when the cleaning liquid flows downward from the side of the bottom wall 15 close to the annular side wall 13 to the cleaning liquid outlet 12, the potential energy generated by the height difference enables the cleaning liquid to flow back as much as possible and impact the inner wall of the injection nozzle 3 when the flow direction is changed at the baffle 121, so as to clean the inner wall.

[0045] Therefore, in this example, the axial height of the baffle plate 121 can be determined according to the depth to which the injection nozzle 3 needs to be immersed. At the same time, the angle between the baffle plate 121 and the bottom wall 15 can also be set according to the cleaning needs.

[0046] It should be noted that when the liquid injection nozzle 3 is placed in the accommodating space through the limiting hole, there is a gap between the liquid injection nozzle 3 and the annular side wall 13, and there is also a gap between the liquid injection nozzle 3 and the bottom wall 15, so as to facilitate the circulation of the cleaning liquid.

[0047] In some optional embodiments, an arc-shaped flow-guiding surface is provided at the connection between the baffle plate 121 and the bottom wall 15 .

[0048] It can be understood that the guide surface makes it easier for the cleaning liquid to change its flow direction, reduces the potential energy lost when the cleaning liquid impacts the baffle plate 121, and avoids the cleaning liquid from flowing back after impacting the baffle plate 121, thereby preventing the cleaning liquid from flowing smoothly into the injection port of the injection nozzle 3.

[0049] In some optional embodiments, a cleaning nozzle 2 is provided in the cleaning liquid inlet 11 , and the cleaning nozzle 2 is used to connect the accommodating space and the cleaning liquid storage tank 8 , and the liquid outlet of the cleaning nozzle 2 faces the bottom wall 15 and is spaced apart from the cleaning liquid outlet 12 .

[0050] It can be understood that when the cleaning liquid flows out from the liquid outlet of the cleaning nozzle 2, the farther away from the cleaning liquid outlet 12, the greater the potential energy of the cleaning liquid flowing toward the baffle 121. Of course, the liquid outlet of the cleaning nozzle 2 can also be directed toward the gap between the liquid outlet of the injection nozzle 3 and the above-mentioned cleaning container 1, that is, the part where the baffle 121 does not overlap with the injection nozzle 3, and by giving the cleaning liquid sufficient hydraulic pressure, the baffle 121 is impacted to make the cleaning liquid flow back to the inner wall of the injection nozzle 3.

[0051] In some optional embodiments, the cleaning container 1 further includes a cup body 17, which is connected to the annular side wall 13 and formed integrally therewith, the cleaning liquid outlet 12 is connected to the cavity of the cup body 17, and is sealed to the cover body 14 via a sealing gasket 16, and the limiting hole is adapted to the size of the liquid injection nozzle 3 so that when the liquid injection nozzle 3 is placed in the accommodating space, the limiting hole is closed.

[0052] That is, when the liquid injection nozzle 3 is placed on the cover body 14, the accommodating space has only the cleaning liquid inlet 11 and the cleaning liquid outlet 12 for communicating with the outside, so that the cleaning liquid can flow completely through the above-mentioned channels to avoid leakage. At the same time, it is also convenient to pressurize the cleaning liquid to adjust the cleaning strength.

[0053] In this example, the cup body 17 has a conical cavity, the bottom wall 15 is located at the cup mouth, and the accommodating space is connected to the cavity of the cup body 17 through the cleaning liquid outlet 12 .

[0054] In some optional embodiments, such as Figure 3 As shown, the above-mentioned liquid injection nozzle cleaning tool also includes a cleaning liquid recovery component 7, and the cleaning liquid recovery component 7 is connected to the above-mentioned cleaning liquid outlet 12 for collecting the cleaning liquid.

[0055] It can be understood that after cleaning, the cleaning liquid flows out from the cleaning liquid outlet 12. Since the cleaning liquid contains residual electrolyte and electrolyte crystals, they need to be properly collected to prevent contamination.

[0056] Furthermore, the cleaning container 1 is connected to a liquid outlet pipe 4 connected to the cleaning liquid outlet 12, the cleaning liquid recovery assembly 7 includes a cleaning liquid recovery box 71 and a filter plate 72, the cleaning liquid recovery box 71 has a recovery chamber, and the outlet of the liquid outlet pipe 4 is connected to the recovery chamber; a plurality of filter plates 72 are arranged at intervals in the recovery chamber, and each of the filter plates 72 is provided with a plurality of filter holes for gas circulation, and the filter holes of different filter plates 72 are arranged in an alternating manner, and the filter plates 72 and the outlet of the liquid outlet pipe 4 are arranged relatively at intervals.

[0057] It can be understood that the cleaning liquid flowing out of the cleaning liquid outlet 12 flows into the cleaning liquid recovery box 71 through the liquid outlet pipe 4. When the liquid injection nozzle is completely cleaned, the cleaning liquid between the baffle plate 121 and the annular side wall 13 needs to be completely discharged from the cleaning liquid outlet 12. At this time, stop pouring cleaning liquid into the cleaning liquid inlet 11, and blow a slight positive pressure into the containing space, and blow the mixed liquid of the residual electrolyte and the cleaning liquid into the cleaning liquid outlet 12 bypassing the baffle plate 121. Since the airflow carries the mixed liquid from the liquid outlet pipe 4 into the recovery chamber of the cleaning liquid recovery box 71, it is necessary to separate the gas and the liquid. Through the filter plate 72, the water mist formed by the mixed liquid under the action of positive pressure is blown onto the filter plate 72, the liquid is blocked by the filter plate 72, and the gas passes through the filter hole. After filtering by multiple filter plates 72, the gas and the liquid are separated, the liquid is collected in the cleaning liquid recovery box 71, and the gas is discharged from the cleaning liquid recovery box 71.

[0058] In this example, a plurality of cleaning containers 1 are arranged on the cleaning liquid recovery box 71, and the liquid outlet pipe 4 is arranged in the recovery chamber. The purpose of such arrangement is to simplify the structural arrangement and also to improve the cleaning efficiency.

[0059] Optionally, a placement port connected to the recovery cavity is provided on the cleaning liquid recovery box 71, and a cup body 17 can be placed in each placement port. The liquid outlet pipe 4 is connected to the bottom of the cup and is connected to the cavity of the cup body 17, so that the cleaning liquid flowing out of the cleaning container 1 flows into the cleaning liquid recovery box 71 through the cup body 17 and the liquid outlet pipe 4.

[0060] On the other hand, Figure 4 As shown, the present application also provides a liquid injection nozzle cleaning system, including a cleaning liquid storage tank 8 and any of the above-mentioned liquid injection nozzle cleaning tools.

[0061] It can be understood that the cleaning liquid storage tank 8 stores the cleaning liquid, and can inject the cleaning liquid into the accommodating space of the cleaning container 1 according to a set pressure.

[0062] Furthermore, the cleaning liquid storage tank 8 is connected to the cleaning liquid inlet 11 through a liquid pipeline 6 , and a one-way valve 61 and a liquid control valve 62 are provided on the liquid pipeline 6 .

[0063] Specifically, the cleaning liquid flows from the cleaning liquid storage tank 8 into the liquid pipeline 6 through the liquid outlet ball valve 81, and flows into the cleaning container 1 after adjusting the hydraulic pressure through the liquid control valve 62. Since the one-way valve 61 is provided, the backflow of the cleaning liquid is avoided.

[0064] Preferably, the liquid pipeline 6 is connected to the plurality of cleaning liquid inlets 11 via a bus 5 .

[0065] In this example, multiple liquid injection nozzles 3 can be cleaned simultaneously to improve cleaning efficiency. Therefore, after the cleaning liquid flows out from the liquid control valve 62, it is divided into multiple pipes through the bus 5 to enter the cleaning liquid inlets 11 of different cleaning containers 1 respectively.

[0066] In some optional embodiments, the excess liquid in the bus 5 can flow back to the cleaning liquid storage tank 8 through the pipeline and the liquid return ball valve to avoid the waste of cleaning liquid and save costs.

[0067] It should be noted that both the pipeline flowing out of the cleaning liquid storage tank 8 and the pipeline flowing into the cleaning liquid storage tank 8 are provided with a one-way valve to ensure that the cleaning liquid completes the cleaning and prevents the residual liquid from flowing back.

[0068] Preferably, the cleaning liquid storage tank 8 is also provided with a liquid replenishing mechanism, including a vacuum valve 82, a liquid replenishing valve 83 and a liquid level sensor 84. The vacuum valve 82 is arranged on the air inlet pipeline connected to the cleaning liquid storage tank 8, and is used to extract the gas in the cleaning liquid storage tank 8; the liquid replenishing valve 83 is arranged on the liquid inlet pipeline connected to the cleaning liquid storage tank 8, and is used to control the opening and closing of the liquid inlet pipeline; the liquid level sensor 84 is arranged on the cleaning liquid storage tank 8, and is used to detect the volume of the cleaning liquid in the cleaning liquid storage tank 8, and is connected to the vacuum valve 82 and the liquid replenishing valve 83 by signal.

[0069] During use, when the liquid level sensor 84 detects that the cleaning liquid in the cleaning liquid storage tank 8 does not meet the cleaning requirements, the liquid control valve 62 is closed, the refill valve 83 is opened, and the vacuum valve 82 starts to vacuum, so that the external liquid enters the cleaning liquid storage tank 8 through the refill valve 83 until the liquid level sensor 84 detects that the volume of the cleaning liquid meets the cleaning requirements.

[0070] The working principle of the embodiment of the present application is as follows: the injection nozzle 3 is placed in the limiting hole of the cover body 14, so that the liquid outlet of the injection nozzle 3 is located in the accommodation space, and the injection nozzle 3 is completely closed. The liquid outlet ball valve 81 is opened, and the cleaning liquid flows from the cleaning liquid storage tank 8 into the liquid pipeline 6 through the liquid outlet ball valve 81, and after adjusting the hydraulic pressure through the liquid control valve 62, it is divided into multiple pipelines through the bus 5 to enter the cleaning liquid inlet 11 of different cleaning containers 1 respectively. After the cleaning liquid flows into the accommodation space from the cleaning liquid inlet 11, it flows out from the cleaning liquid outlet 12. The cleaning liquid changes its flow direction at the baffle plate, and the cleaning liquid with changed flow direction can flow back and flush the inner wall of the injection nozzle 3. The cleaning liquid collected between the annular side wall 13 and the baffle plate 121 soaks the liquid outlet of the injection nozzle 3, and the electrolyte crystals attached to the injection nozzle 3 are cleaned more effectively. The cleaning liquid flowing out of the cleaning liquid outlet 12 flows into the cleaning liquid recovery box 71 through the liquid outlet pipe 4. After thorough cleaning, stop pouring cleaning liquid into the cleaning liquid inlet 11, and blow a slight positive pressure into the containing space to blow the mixed liquid of the residual electrolyte and the cleaning liquid into the cleaning liquid outlet 12 bypassing the baffle 121, and through the filter plate 72, the water mist formed by the mixed liquid under the action of positive pressure is blown onto the filter plate 72, the liquid is blocked by the filter plate 72 and the gas passes through the filter holes, and is filtered by multiple filter plates 72 to separate the gas and the liquid, and the liquid is collected in the cleaning liquid recovery box 71, and the gas is discharged from the cleaning liquid recovery box 71.

[0071] The utility model discloses a nozzle cleaning tool and system, by arranging a baffle plate 121 at the cleaning liquid outlet 12 of the cleaning container 1, and when the liquid injection nozzle 3 is placed in the above-mentioned accommodation space, the liquid injection housing of the above-mentioned liquid injection nozzle 3 is arranged outside the above-mentioned baffle plate 121, and there is a gap between the above-mentioned baffle plate 121, so as to form a channel for the cleaning liquid to flow from the cleaning liquid inlet 11 into the accommodation space and then flow out from the cleaning liquid outlet 12, so that during cleaning, the cleaning liquid can change its flow direction at the baffle plate, and the outer wall and the inner wall of the liquid injection nozzle 3 are simultaneously cleaned in the process of flowing through the channel. Cleaning solves the problem of incomplete cleaning of the inner and outer walls when cleaning the injection nozzle 3; the cleaning liquid outlet 12 is located at the bottom of the accommodating space, so that the cleaning liquid can be collected at the groove formed between the annular side wall 13 and the baffle 121, so as to soak the liquid outlet of the injection nozzle 3 and more effectively clean the electrolyte crystals attached to the injection nozzle 3; the cleaning liquid recovery component 7 is used to properly collect the mixed liquid after cleaning, and the filter plate 72 can separate the gas and liquid in the water mist formed by the mixed liquid under the action of positive pressure, which is convenient for collection.
