Description

Hydroextractor that gyro wheel was strengthened

Technical Field

The utility model relates to a sewage treatment device, concretely relates to hydroextractor.

Background

At present, two ends of a roller of a dehydrator are supported by two separated roller shafts respectively, wherein a shaft head part is supported on a bearing of a tile seat, and the shaft head part is thin, and acting force applied to the roller is mainly born by the shaft head part, so that the roller is easy to fatigue fracture. Simply increasing the diameter of the stub shaft results in no room for the opponent to fit in place, and also increases cost.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a hydroextractor that the gyro wheel was strengthened is provided, increases the intensity at gyro wheel axle spindle nose position, avoids fatigue fracture.

In order to solve the technical problem, the utility model adopts the following technical scheme: the utility model provides a hydroextractor that gyro wheel was strengthened, includes hollow structure's gyro wheel, with gyro wheel end connection's roller shaft, support the bearing at roller shaft head position, the bearing frame of installation bearing, the inner of roller shaft stretch into the gyro wheel and with between the gyro wheel inner wall welded fastening have interior barricade, welded fastening has outer barricade between the outer end inner wall of gyro wheel and the roller shaft, the axle head position overcoat axle sleeve between bearing frame and outer barricade, barricade and ring full weld connection outside the inner laminating of axle sleeve, the outer end and the roller shaft welding of axle sleeve.

Optionally, the roller shaft is provided with a positioning step which forms axial positioning with the inner retaining wall and the outer retaining wall.

Optionally, the roller shaft is fully welded with the inner retaining wall, the outer retaining wall and the shaft sleeve ring.

Optionally, the axle head part of the roller axle extends out of the bearing seat and is sleeved with the water retaining cover.

The utility model adopts the above technical scheme, following beneficial effect has:

1. the shaft sleeve is sleeved between the bearing seat and the outer retaining wall, one end of the shaft sleeve is in full welding with the shaft head ring, and the other end of the shaft sleeve is in full welding with the outer retaining wall ring, so that the fatigue resistance of the shaft head can be improved, the small-specification shaft head counter-hand piece can be selected, the mounting position of the small-specification shaft head counter-hand piece is more flexible, and the material cost of the shaft head is reduced.

2. The roller shaft is provided with a positioning step which forms axial positioning with the inner retaining wall and the outer retaining wall, so that welding is facilitated, and welding firmness is improved. The roller shaft is fully welded with the inner retaining wall, the outer retaining wall and the shaft sleeve, so that the welding firmness is ensured.

3. The shaft head part of the roller shaft is exposed outside after being assembled with a tile seat (bearing seat). When the high-pressure water gun is used by an equipment operator for maintenance, water is easily flushed onto the shaft head and the tile seat, so that rusting, damage to a tile seat functional part and the like are caused. The water retaining cover is arranged to effectively prevent water splash from directly splashing on the shaft head, and the water retaining effect is achieved.

The specific technical solution and the advantages of the present invention will be described in detail in the following detailed description with reference to the accompanying drawings.

Drawings

The invention will be further described with reference to the accompanying drawings and specific embodiments:

fig. 1 is a schematic structural diagram of a first embodiment of the present invention;

fig. 2 is a schematic structural diagram of a second embodiment of the present invention.

Detailed Description

Example one

As shown in fig. 1 and 2, a hydroextractor that gyro wheel was strengthened, including hollow structure's gyro wheel 1, with gyro wheel end connection's gyro wheel axle 2, support the bearing at gyro wheel axle spindle nose position, the bearing frame 3 of installation bearing, the inner of gyro wheel axle stretch into the gyro wheel and with the gyro wheel inner wall between welded fastening have interior barricade 11, welded fastening has outer barricade 12 between the outer end inner wall of gyro wheel and the gyro wheel axle, the axle nose position overcoat axle sleeve 22 between bearing frame and outer barricade, the inner laminating outer barricade of axle sleeve and ring full weld are connected, the outer end and the gyro wheel axle welding of axle sleeve. The added shaft sleeve can increase the fatigue resistance of the shaft head, and a small-specification shaft head counter-hand piece can be selected, so that the mounting position of the counter-hand piece has more flexibility, and the material cost of the shaft head is reduced.

Further, the roller shaft 2 is provided with a positioning step 21 which forms an axial positioning with the inner retaining wall 11 and the outer retaining wall 12. The welding is convenient and the welding firmness is improved. The roller shaft 2, the inner retaining wall 11, the outer retaining wall 12 and the shaft sleeve 22 are all fully welded in a ring shape, so that the welding firmness is ensured.

Example two

Referring to fig. 2, on the basis of the first embodiment, the axle head part of the roller axle extends out of the bearing seat and is sleeved with the water retaining cover 4. The water splash is effectively prevented from directly splashing on the shaft head by the structural design, and the water retaining effect is achieved.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and those skilled in the art should understand that the present invention includes but is not limited to the contents described in the above specific embodiments. Any modification which does not depart from the functional and structural principles of the present invention is intended to be included within the scope of the claims.
