Background
Wet material conveying is easier to pollute the bearing at the shaft end by seepage and powder materials because of seepage. For example, chinese patent publication No. CN216746833U discloses a leached wet cake sampling device and a conveying system thereof, wherein the conveying system adopts a screw conveyor, the screw conveyor comprises a housing tube, a screw rotor is arranged in the housing tube, and two shaft ends of the screw rotor are respectively supported in a bearing seat.
In order to ensure good lubrication of the bearing and avoid pollution of feed liquid in conveyed materials to the bearing, one scheme in the prior art is to arrange the bearing externally, a shaft sealing device is arranged at the position of the screw shaft penetrating through the end cover, and a bearing seat is positioned at the outer side of the shaft sealing device. The scheme has the advantages that: the bearing has the advantages of clean working environment, good lubrication and good reliability. The disadvantages are: the shaft seal device cannot stop leakage, particularly alkane, diethyl ether, acetone and the like with extremely high permeability, and in order to reduce leakage at the shaft seal, the sealing packing is usually tightly pressed, so that the shaft neck is worn too fast, and the rotating shaft is scrapped due to serious wear.
The other scheme is that a self-aligning built-in shaft device is adopted, a bearing seat is arranged at a hole of an end plate and is sealed through a sealing gasket, a self-aligning bearing is arranged in a central hole of the bearing seat, a framework oil seal and other sealing devices are arranged on the inner side of the self-aligning bearing, and the outer port of the bearing seat is sealed by a sealing end cover. The scheme has the advantages that: the aligning bearing is in the closed space, and the flange of the bearing seat and the outer port of the bearing seat are both static seals, so that the sealing is very reliable, and leakage of solvents such as alkane, diethyl ether, acetone and the like with extremely high permeability can be avoided. The disadvantages are: the working environment of the aligning bearing is easy to produce pollution, no lubrication is caused, and the conventional bearing is easy to produce blockage or damage.
The other scheme is that a built-in cylindrical sliding bearing is adopted, a bearing seat is arranged at a hole of an end plate and is sealed through a sealing gasket, the cylindrical sliding bearing is sleeved at the shaft end and is positioned in a central hole of the bearing seat, and the outer port of the bearing seat is sealed by a sealing end cover. The scheme has the advantages that: the cylindrical sliding bearing is positioned in the closed space, and the flange of the bearing seat and the outer port of the bearing seat are both in static seal, so that leakage of solvents such as alkane, diethyl ether, acetone and the like with extremely high permeability can be avoided. The disadvantages are: the working environment of the built-in cylindrical sliding bearing is easy to pollute, only seepage plays a certain role in lubrication, and interference, abrasion, blocking or damage are easy to generate by adopting a conventional bearing.
