Inside the cylinder body, there are a magnetic column top plate and a magnetic column bottom plate. Between the magnetic column top plate and the magnetic column bottom plate, there are several magnetic columns and magnetic column pull rods arranged parallel to each other.

[0004] Although the above technical solution can achieve the operation of removing iron from battery slurry, its overall effect is single. It is difficult to filter the slurry while removing iron, and the structure is fixed and not convenient to move, thus it is difficult to meet the working requirements. Content of the Utility Model

[0005] The purpose of the utility model is to provide a dynamic iron removal trolley for battery slurry to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A dynamic iron removal trolley for battery slurry, including a trolley main body.

[0013] The utility model provides a battery slurry dynamic iron removal trolley, which has the following beneficial effects:

[0014] (1) In the utility model, the rotation of the filter cartridge drives the strong magnetic rod to rotate synchronously. While the strong magnetic rod adsorbs the iron filings contained in the slurry, the filter cartridge filters the slurry. The rotation of the filter cartridge drives the force receiving block to rotate. During the rotation of the force receiving block, the fixed block is extruded. At this time, the force receiving block drives the movable block to move inside the movable groove when being extruded. While the movable block moves to drive the scraping plate to clean the inner wall of the filter cartridge, the scraping plate extrudes the knocking ball. When the knocking ball is extruded, the movable plate is driven to extrude the first spring and contract into the activity cavity. When the knocking ball is released from the extrusion, the first spring drives the knocking ball to reset and knock the inside of the filter cartridge to generate vibration, achieving the effect of iron removal and filtering the slurry at the same time.

[0015] (2) In the utility model, by moving the extrusion plate inward, the extrusion plate moves inside the limiting groove to extrude the limiting block. While the limiting block is extruded, it extrudes the second spring and enters the storage cavity. At this time, the filter cartridge is separated from the connection with the installation base, and the filter cartridge can be moved upward, realizing the effect of quickly disassembling and installing the filter cartridge, which greatly saves working time.

[0023] Among them, a fixed rod 78 is fixedly connected to the bottom end inside the filter cylinder 71. A movable cavity 79 is formed inside the fixed rod 78.

[0024] Through the fixed rod 78, the fixed rod 78 can squeeze the force - receiving block 75 during the rotation of the filter cylinder 71.

[0025] Among them, a first spring 710 is fixed to the inner wall of the movable cavity 79, and a movable plate 711 is fixedly connected to the outer wall of the first spring 710.

[0026] Through the first spring 710, the first spring 710 can drive the movable plate 711 to reset without being affected by external forces.

[0027] Among them, the movable plate 711 passes through and is slidably connected to the inside of the fixed rod 78, and a percussion ball 712 is fixedly connected to one end of the movable plate 711 located outside the fixed rod 78.

[0028] Through the percussion ball 712, the movement of the percussion ball 712 can strike the filter cartridge 71, thereby causing the filter cartridge 71 to vibrate.

[0029] Among them, a limiting device 8 is arranged at the inner bottom end of the outer cylinder 4, an installation base 81 is fixedly connected to the inner bottom end of the outer cylinder 4, and the bottom end of the installation base 81 is fixedly connected to the top end of the motor 5.

[0030] Through the installation base 81, the installation base 81 can drive the filter cartridge 71 to rotate, thereby filtering the slurry by using centrifugal force.

[0035] The present utility model provides a battery slurry dynamic iron removal trolley, and the specific working principle is as follows:

[0036] During use, open the top plate 6 and pour the slurry to be de-ironed into the interior of the filter cylinder 71. Start the motor 5, and the motor 5 drives the filter cylinder 71 to rotate. The rotation of the filter cylinder 71 drives the strong magnetic rod 72 to rotate synchronously. While the strong magnetic rod 72 adsorbs the iron filings contained in the slurry, the filter cylinder 71 filters the slurry. The rotation of the filter cylinder 71 drives the force-receiving block 75 to rotate. During the rotation of the force-receiving block 75, it squeezes the fixed block 77. At this time, the force-receiving block 75 being squeezed drives the movable block 74 to move inside the movable groove 73. The movement of the movable block 74 drives the scraper 76 to clean the inner wall of the filter cylinder 71. At the same time, the scraper 76 squeezes the knocking ball 712. When the knocking ball 712 is squeezed, it drives the movable plate 711 to squeeze the first spring 710 and contract into the interior of the movable cavity 79. When the knocking ball 712 is released from the squeeze, the first spring 710 drives the knocking ball 712 to reset and knock the interior of the filter cylinder 71 to cause vibration. If it is necessary to disassemble and clean the filter cylinder 71, move the pressing plate 86 inward. The pressing plate 86 moves inside the limiting groove 85 to squeeze the limiting block 84. While the limiting block 84 is being squeezed and compresses the second spring 83, it enters the interior of the storage cavity 82. At this time, the filter cylinder 71 is disengaged from the connection with the mounting base 81, and the filter cylinder 71 can be moved upward.
