Description

Technical Field

[0001] This utility model belongs to the technical field of drum magnetic separator equipment, and specifically relates to a special device for disassembling the aluminum end cap of a drum magnetic separator. Background Technology

[0002] Currently, during the operation of drum magnetic separators in mineral processing plants, when magnetic blocks on the internal magnetic system fall off or the rubber rollers on the outside of the drum are damaged, the aluminum end caps of the drum magnetic separator must be removed for maintenance. Since the bearing in the bearing chamber at the center of the aluminum end cap is assembled with the drum's main shaft, the bearing must be removed first when disassembling the aluminum end cap. Because there are no special tools for disassembling the bearing, gas welding is required. Since the inside of the drum of the drum magnetic separator is in a sealed state, the high-temperature oil and gas generated during gas welding of the bearing could enter the sealed drum and, if it reaches a certain volume, could potentially explode inside the drum, posing a significant risk of injury to maintenance personnel and damage to the equipment.

[0003] Furthermore, the annular joint connecting the aluminum end cap and the roller is sealed. Because the joint is firmly attached, disassembly can only be achieved by inserting a wedge into the gap at the joint and then striking it with a sledgehammer. This method of disassembly is extremely prone to damaging the edges of the aluminum end cap, rendering it unusable and irreparable. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in existing methods for disassembling the aluminum end caps of cylindrical magnetic separators, and to provide a device for disassembling the aluminum end caps of cylindrical magnetic separators. This device improves maintenance efficiency, ensures the safety of maintenance personnel and prevents equipment damage, reduces the consumption of spare parts, and lowers production costs.

[0005] A device for disassembling the aluminum end cap of a cylindrical magnetic separator includes a hydraulic puller, a pull ring base, and bolts;

[0006] The pull ring base consists of a pull ring and a base. The pull ring is U-shaped, and the base is disc-shaped or square. The pull ring is fixedly connected to the base, and a bolt hole is provided in the center of the base.

[0007] The bolt is threaded into the bolt hole, and the pull ring of the pull ring base is connected to the hydraulic puller.

[0008] Furthermore, in the aforementioned device for disassembling the aluminum end cap of the cylindrical magnetic separator, the hydraulic puller is a three-jaw hydraulic puller, with each claw corresponding to a pull ring base.

[0009] Furthermore, in the aforementioned device for disassembling the aluminum end cap of the cylindrical magnetic separator, there are several pull ring bases.

[0010] Furthermore, in the aforementioned device for disassembling the aluminum end cap of the cylindrical magnetic separator, the distance between the pull ring of the pull ring base and the base is greater than the length of the bolt.

[0011] Compared with the prior art, the advantages of this utility model are:

[0012] 1. When using this method to disassemble the aluminum end cap, the bearing is also disassembled, eliminating the need for gas welding and cutting, thus ensuring the personal safety of maintenance personnel during operation.

[0013] 2. Saves time during disassembly and increases work efficiency.

[0014] 3. Reduced consumption of spare parts and components, thus lowering production costs. Attached Figure Description

[0018] Example

[0019] Specialized device for disassembling the aluminum end cover of a drum magnetic separator, see [link / details]. Figure 1 and Figure 2 It includes a three-jaw hydraulic puller, three pull ring bases, and three bolts;

[0020] The hydraulic puller is equipped with a puller hydraulic rod and an oil pressure starting rod. The pull ring base consists of a pull ring and a base. The pull ring is U-shaped and the base is disc-shaped or square. The pull ring is fixedly connected to the base, and the center of the base is provided with a bolt hole.

[0021] The bolt is threaded into the bolt hole, and the pull rings of the three pull ring bases are respectively connected to the three claws of the hydraulic puller.

[0022] The distance between the pull ring and the base of the pull ring base is greater than the length of the bolt.

[0023] The method of using this device is as follows: when it is necessary to remove the aluminum end cover of the drum of the drum magnetic separator:

[0024] 1. Before disassembling the aluminum end cap, first remove the outer transmission sleeve of the aluminum end cap, and at the same time remove the fixing screws between the aluminum end cap and the cylinder.

[0025] 2. Screw the three bolts from the bolt holes of the pull ring base into the screw holes inside the aluminum end cap for fixing the transmission sleeve, so that the three pull ring bases are respectively fixed on the outside of the aluminum end cap;

[0026] 3. Place the hydraulic starter rod of the hydraulic puller against the shaft head of the magnetic separator, hook the three claws of the puller onto the pull ring base, adjust the position of the claws and the starter rod, and tighten the screws of the claw base;

[0027] 4. Manually swing the hydraulic lever of the hydraulic puller to move the hydraulic starter lever forward and the corresponding hook claw backward, pulling out the aluminum end cap along with the bearing at the same time, thus completing the aluminum end cap disassembly.
