Abstract
Description
Technical Field
[0001] This application relates to the field of lithium battery processing. Specifically, it relates to a dynamic inflatable sealed iron remover. Background Art
[0002] During the production process of lithium batteries, some impurities may be mixed in, such as metal elements like iron. These impurities may have an adverse impact on battery performance, for example, reducing the battery's capacity and cycle life. Therefore, it is necessary to perform iron removal treatment on lithium batteries during the production process to remove metal elements such as iron. The iron remover is a device specifically used to remove metal impurities, which can effectively remove metal elements such as iron in lithium batteries and improve the purity and performance of the batteries.
[0003] The existing technology mainly withdraws the magnetic rod adsorbed with magnetic substances from the slurry pipeline and performs manual or semi-automatic iron removal outside the pipeline. The so-called manual iron removal means manually using tools to scrape the slurry with a high iron concentration adsorbed on the magnetic rod into a waste bucket; the so-called semi-automatic iron removal means that the action of scraping the slurry from the magnetic rod can be automated, and the waste slurry with a high concentration flowing to the bottom surface of the magnetic rod still needs to be manually removed additionally; in addition, the removed waste slurry requires an additional transfer device for subsequent transfer treatment.
[0004] The common disadvantage of the above two existing iron removal methods is that the slurry will be exposed to the air, and the slurry will emit pungent and toxic odors, which is very unfriendly to personnel and the environment.
[0005] In addition, manual iron removal has disadvantages such as long operation time and the need to specially allocate cleaning personnel; while semi-automatic iron removal can only automatically remove the slurry on the outer cylindrical surface of the magnetic rod, and the waste slurry with a high concentration flowing to the bottom surface of the magnetic rod still needs to be manually removed additionally;
[0006] In addition, both manual and semi-automatic methods require an additional transfer device to perform subsequent transfer treatment on the removed waste slurry, and the entire processing link is cumbersome. Summary of the Utility Model
[0007] The main purpose of this application is to provide a dynamic inflatable sealed iron remover, in which the cleaning action is automatically carried out entirely within a closed pipeline, and the slurry will not be exposed to the air, so that no pungent and toxic gas will be emitted into the environment, and there is no need to manually remove the slurry on the bottom end surface of the magnetic rod.
[0008] To achieve the above object, in a first aspect, the present application provides a dynamic inflatable sealed iron remover, which includes an outer casing pipe, and at least one set of iron removal devices fixedly arranged in the outer casing pipe. The iron removal device includes a first fluid pipe, a second fluid pipe, a magnetic rod slidably arranged in the first fluid pipe and the second fluid pipe, and an iron removal assembly arranged between the first fluid pipe and the second fluid pipe. The iron removal assembly includes a fixedly arranged chuck seal seat, an annular inflatable device fixedly arranged on the chuck seal seat, and a charging / discharging air pipe connected to the annular inflatable device. When the annular inflatable device is in an inflated state, it closely adheres to the magnetic rod, and when the annular inflatable device is in a deflated state, there is a gap for fluid to pass between it and the magnetic rod.
[0009] Further improved, the chuck seal seat is detachably connected to the first fluid pipe and the second fluid pipe.
[0010] Further improved, the chuck seal seat is connected to the first fluid pipe and the second fluid pipe through quick clamps.
[0011] Further improved, a sealing structure is arranged between the chuck seal seat and the quick clamp.
[0012] Further improved, it further includes a third fluid pipe, and the iron removal device is arranged between the third fluid pipe and the second fluid pipe.
[0013] Further improved, the annular inflatable device is an inflatable sealing ring or an inflatable airbag.
[0014] Further improved, a fluid injection port communicating with its inner cavity is opened on the second fluid pipe.
[0015] Compared with the prior art, the beneficial effects of the dynamic inflatable sealed iron remover provided by the present utility model are as follows. First, the iron removal device is arranged in the outer casing pipe, so iron removal is carried out inside the pipe. The cleaning action is all carried out inside the closed pipe, and the slurry will not be exposed to the air, so no pungent and toxic gas will be emitted into the environment. In addition, the action of removing the impurity slurry from the magnetic rod is fully automatic, and there is no need to manually remove the slurry at the bottom end face of the magnetic rod. Finally, the removed impurity slurry directly flows into the subsequent link in the waste discharge pipe, and the waste liquid does not need to be transferred in the middle, which is simple and environmentally friendly.

[0028] It should be noted that, without conflict, the embodiments and features in the embodiments of this application can be combined with each other. The following will describe this application in detail with reference to the drawings and in combination with the embodiments.
[0029] Embodiment 1:
[0030] As Figure 1 shown, a dynamic inflatable sealed iron remover includes an outer shell body pipeline, and at least one set of iron removal devices fixedly arranged in the outer shell body pipeline. When multiple sets of iron removal devices are provided, each iron removal device is independently arranged and can circulate different media.
[0031] As Figures 3 - 4 shown, the iron removal device includes a first fluid pipeline, a second fluid pipeline, a magnetic rod slidably arranged in the first fluid pipeline and the second fluid pipeline, and an iron removal component arranged between the first fluid pipeline and the second fluid pipeline. The iron removal component includes a fixedly arranged chuck seal seat, an annular inflatable device fixedly arranged on the chuck seal seat, and a charging / discharging pipeline connected to the annular inflatable device. The annular inflatable device is an inflatable sealing ring or an inflatable airbag. In this embodiment, an inflatable sealing ring is preferably adopted. When the annular inflatable device switches states, such as during normal slurry transportation, the gas in it is discharged by opening its charging / discharging pipeline. When an iron removal operation is required, compressed air source is used to inflate the annular inflatable device.
[0032] When the annular inflatable device is in the inflated state, it clings to the magnetic rod. When the annular inflatable device is in the deflated state, there is a gap for fluid to pass between it and the magnetic rod.
[0033] In the state of normal slurry transportation, the cavity of the first fluid pipeline is the main slurry pipeline, and the magnetic substances in the slurry will be adsorbed on the surface of the magnetic rod; at this time, the annular inflatable device is in the deflated state, that is, not inflated, its inner diameter becomes larger, and after becoming larger, it disengages from the magnetic rod and maintains a sufficient gap.
[0034] The state where the iron removal action needs to be performed. At this time, the annular inflatable device is inflated. After it expands, its inner diameter becomes smaller and it tightly holds the magnetic rod with an appropriate pressing force to achieve the sealing of the first fluid pipeline. The magnetic rod moves upward. At this time, iron filings and impurities are removed from the magnetic rod under the scraping action of the annular inflatable device and flow into the second fluid pipeline.
[0035] It should be noted that the action of removing impurity slurries above and below the magnetic rod is fully automated and does not require manual operation. In addition, since the lowermost end face of the magnetic rod is always located in the second fluid pipeline and will not enter the first fluid pipeline, it is not necessary to remove the impurity slurries on the bottom end face of the magnetic rod. The second fluid pipeline is a sealed cavity and can be connected to subsequent waste liquid treatment equipment. Since it does not directly contact the outside air, it will not emit pungent and toxic gases into the environment. The removed impurity slurries directly flow into the subsequent link in the waste discharge pipeline, and the waste liquid does not need intermediate transfer, which is simple, environmentally friendly and can achieve the automated recovery and treatment of waste slurries.
[0036] Preferably in this embodiment, the chuck seal seat is detachably connected to the first fluid pipeline and the second fluid pipeline. Further, the chuck seal seat is connected to the first fluid pipeline and the second fluid pipeline through quick clamps. In order to improve the sealing effect, a sealing structure is provided between the chuck seal seat and the quick clamps. The sealing structure can preferably adopt a gasket. Of course, in addition to this, any sealing structure that can seal two fixed components can be used here.
[0037] Embodiment 2, as Figure 5 shown, the difference from Embodiment 1 is that an additional fluid pipeline and an iron removal component are provided. Specifically, it further includes a third fluid pipeline. An iron removal device is provided between the third fluid pipeline and the second fluid pipeline. A fluid injection port communicating with its inner cavity is opened on the second fluid pipeline.
[0038] In this embodiment, the first fluid pipeline is also the main fluid pipeline, the second fluid pipeline becomes the cleaning medium pipeline, and the function of the third fluid pipeline is similar to that of the second fluid pipeline in Embodiment 1 and is a waste discharge pipeline.
[0039] In this embodiment, the working principle of iron removal is similar to that of Embodiment 1. An additional cleaning medium pipeline is provided, and its main function is to automatically clean the iron filings adhering to the surface of the annular inflatable device and the bottom of the magnetic rod, so that manual cleaning is not required.
[0040] In addition, a medium inlet and a medium outlet are also provided on the second fluid pipeline. The cleaning medium enters from the medium inlet and then exits from the medium outlet. Thus, not only cleaning is achieved, but also pollution of the waste slurry can be avoided, and the waste slurry has recycling value.
[0041] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
