Description

Technical Field

[0001] This utility model relates to the field of half-shaft technology, specifically to the half-shaft structure of a double-roll magnetic separator. Background Technology

[0002] Double-roll magnetic separators are commonly used magnetic separation equipment in fields such as mineral processing and building material purification. Their core working components are two parallel magnetic separation drums. Magnetic minerals are adsorbed by the magnetic field on the surface of the drums, while non-magnetic minerals fall from the gap between the two drums or the sealing gap between the drums and the machine body under the action of gravity, which is the "leakage point".

[0003] The existing double-roll magnetic separator's half-shaft has the following technical defects: insufficient length design. The traditional half-shaft is designed to be too short, resulting in the bearing housing being installed close to the drum end cover and the material leakage point; insufficient dust protection and structural adaptability. Although some structures are equipped with dust protection components, the short half-shaft limits the mating space between the dust protection plate and the bearing housing. The dust protection effect is easily affected by the assembly precision. Dust entering the bearing housing will aggravate bearing wear and shorten the equipment life.

[0004] Insufficient length design leads to material leakage accumulating around the bearing housing during equipment operation. With equipment vibration or airflow, the leaked material can penetrate into the bearing. Inadequate dust prevention and structural compatibility allow dust to enter the bearing housing, accelerating bearing wear and shortening equipment life. Utility Model Content

[0005] The purpose of this utility model is to provide a half-shaft structure for a double-roller magnetic separator to solve the problems mentioned in the background art, such as insufficient length design, easy component interference during assembly, and cumbersome operation when disassembling and replacing bearings and other components during maintenance, as well as insufficient dust prevention and structural compatibility, which can aggravate bearing wear and shorten the equipment life after dust enters the bearing housing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a half-shaft structure for a double-roller magnetic separator, comprising a half-shaft, wherein the half-shaft is inserted into a body, and a frame is connected to the outside of the body. The frame is used to fix the half-shaft. The half-shaft is an extended half-shaft, and a roller connecting section, a transition section, and a bearing mating section are sequentially arranged.

An arc-shaped plate is connected to the side of the dustproof plate near the bearing seat, and the arc-shaped plate is snapped onto the outside of the bearing seat. A collar is connected to the side of the dustproof plate away from the bearing seat, and the collar is used to fit the half-shaft.

[0007] Preferably, the bearing housing includes a fixed seat, a top cover, and a bearing. The bearing is inserted between the fixed seat and the top cover. A positioning bolt is inserted into the fixed seat and passes through the fixed seat to be inserted into the frame. A connecting bolt is inserted into the inner side of the top cover and passes through the top cover to be inserted into the inner side of the fixed seat.

[0008] Preferably, the machine body includes a casing and a conveyor belt, the conveyor belt being located inside the casing, and the inside of the casing being provided with a raw material bin, a first sorting hopper, and a second sorting hopper.

[0009] Preferably, the conveyor belts are provided in two sets, one set of which is located below the raw material silo and above a first sorting hopper, and the other set of which is located above a second sorting hopper, and the two sets of conveyor belts are arranged in a stepped manner.

[0010] Preferably, a support roller and a magnetic roller are inserted into the inner side of the conveyor belt, with the support roller inserted into the inner side of the housing and the magnetic roller sleeved on the outer side of the half shaft.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. The half-shaft structure of this double-roll magnetic separator extends the half-shaft length, keeping the bearing housing away from the material leakage accumulation area, thus eliminating the possibility of material leakage entering the bearing.

[0014] 2. The half-shaft structure of this double-roll magnetic separator features a dual limiting structure where the dustproof plate is snapped into the bearing seat by an arc plate and the collar is fixed to the half-shaft. Combined with the fitting space provided by the extended half-shaft, the possibility of dust entering the bearing seat is greatly reduced, and the service life of the bearing is extended.

[0015] 3. The half-shaft structure of this double-roll magnetic separator only requires optimization of the half-shaft length and the addition of a dustproof baffle ring.
