Abstract
Description
Technical Field
[0001] The utility model belongs to the field of demagnetization and deironing devices in metallochemical production, and particularly relates to a demagnetization plate truck in the production area of lithium iron phosphate. Background Art
[0002] Lithium iron phosphate has the characteristics of low cost, high safety performance, good cycle performance, etc., and is increasingly favored by the power battery and energy storage fields. When magnetic foreign matters (such as Fe, Cr, Ni, Zn and other simple substances, alloys or oxides) appear in the lithium battery cathode material, the battery made of this material will short-circuit due to the self-discharge of magnetic substances, causing the battery to overheat, reach high temperature, and even explode. Moreover, when making the electrode sheet, the thickness of the aluminum foil used in the coating process is only between 0.01 - 0.015 mm. Under high pressure, if there are metal particles hidden in the lithium iron phosphate, it is very easy to cause damage to the metal foil, which not only increases the cost of battery manufacturing, but also affects the reputation of lithium iron phosphate manufacturers and damages the brand image of the enterprise. It can be said that the impact is profound. Therefore, the demagnetization and deironing work is the most basic work with the highest priority in any cathode material production enterprise.
[0003] However, due to the small volume, small magnetic absorption area, and low automation degree of the current deironing (demagnetization) trucks on the market, and in order to increase the demagnetization intensity as much as possible, the chassis of the trolley is designed to be relatively low, and it is very easy to scratch the epoxy floor due to the operator's mistake under the double-wheel support, increasing the maintenance cost of the epoxy floor. Therefore, redesigning a semi-automatic demagnetization truck that can not only save manpower but also protect the epoxy floor is of great help to the production process control of lithium iron phosphate and the maintenance of the workshop environment.
[0004] A manual permanent magnet deironing truck in the prior art includes a vehicle body, support wheels are arranged on both sides of the vehicle body, and a deironing part is arranged inside the vehicle body; the deironing part includes a deironing box arranged inside the vehicle body, the deironing box is slidably connected with the vehicle body up and down, which increases the processing cost of the frame. At least one permanent magnet is arranged inside the deironing box, but the shape of the permanent magnet is not determined. If the magnetic absorption effect is to be enhanced, it must be processed into a shape that conforms to the size of the deironing box. A vehicle bottom plate for supporting the deironing box is arranged at the lower end of the vehicle body, and the vehicle bottom plate is made of non-magnetic material. This vehicle bottom plate is a fixed support and cannot adapt to demagnetization in multiple terrains. The deironing truck is a fully manual device, and the demagnetization coverage area is small, which is not suitable for large-area demagnetization operations.
[0005] A permanent magnet iron removal trolley in the prior art includes a frame, traveling wheels, a permanent magnet rotating cylinder, permanent magnets, a scraping plate, a material container, and a trolley handle. The trolley handle is connected to the frame, the frame is connected to the traveling wheels, the traveling wheels are connected to the permanent magnet rotating cylinder. The design of the permanent magnet rotating cylinder is relatively complex. Although it has a material collecting function, it is not easy to repair. After being damaged, special accessories need to be purchased for replacement, and the maintenance cost is relatively high. Permanent magnets are arranged inside the permanent magnet rotating cylinder, a scraping plate is arranged outside the permanent magnet rotating cylinder, and a material container is arranged below the scraping plate. The permanent magnet iron removal trolley is also a manual device, and it is too large in size, not easy to move, and not convenient for large-area demagnetization work in various terrains.
[0006] Therefore, the existing demagnetization device needs to be further designed and upgraded. Content of the Utility Model
[0007] Aiming at the deficiencies existing in the prior art, the present utility model provides a demagnetization plate trolley for the lithium iron phosphate production area, and the technical problem to be solved is to provide a demagnetization plate trolley that can increase the demagnetization coverage area and reduce the damage of the demagnetization trolley to the epoxy floor; realize multiple functions such as single demagnetization, floor washing before demagnetization, etc., increase multiple choices for on-site demagnetization methods, and save labor costs and time costs.

[0035] To better understand the purpose, structure and function of the present invention, the following further details a magnetic removal plate truck in the lithium iron phosphate production area of the present invention with reference to the accompanying drawings.
[0036] Example 1
[0037] As Figure 1 shown, the present invention provides a magnetic removal plate truck in the lithium iron phosphate production area, including a vehicle frame and a magnetic disk 1. The vehicle frame includes a vehicle frame bottom plate 2 and a vehicle frame main body 3, and the vehicle frame main body 3 is fixedly connected to one side of the upper surface of the vehicle frame bottom plate 2;
[0038] A strong magnetic plate is embedded inside the magnetic disk 1. The bottom surface of the magnetic disk 1 is movably connected to the upper surface of the vehicle frame bottom plate 2, and the upper surface of the magnetic disk 1 is movably connected to the vehicle frame main body 3; a universal wheel 7 is provided at the middle position of the front end of the vehicle frame bottom plate 2, and fixed wheels 6 are respectively provided on both sides of the rear end of the vehicle frame bottom plate 2.
