[0027] See also Figures 2 to 3 A slurry pump bearing box shown includes a base 100 and a bearing box body 200. The bearing box body 200 is arranged on the base 100. The bearing box body 200 includes a pair of semi-circular arc shells 210 aligned and assembled in the horizontal direction. The area enclosed by the pair of semi-circular arc shells 210 forms an axial cavity 220. The pair of semi-circular arc shells 210 are connected by a detachable component 230. The bearing box body 200 is formed by a pair of semi-circular arc shells 210 aligned and assembled in the horizontal direction. When assembling the bearing box, there is no need to use matching lifting ears, and there is no need to lift the bearing box separately. The rotor component 300 can be assembled first and then placed in one side of the semi-circular arc shell 210, and then the other half of the semi-circular arc shell 210 is buckled, thereby improving assembly efficiency and saving production costs.

[0028] In this embodiment, the top of the base 100 has a mounting platform 110, and a plurality of connecting holes 111 are provided on the mounting platform 110. The bottoms of a pair of semicircular arc-shaped shells 210 are arranged on the mounting platform 110 through connecting pieces 112 that match the connecting holes 111.

In addition, the utility model does not require the bracket cover of the traditional bearing box, which greatly saves the mold cost in the development cost. When the slurry pump bearing fails, there is no need to remove the slurry pump head. The bearing can be repaired by removing the bearing box bolts. When the slurry pump bearing is scrapped and needs to be replaced, the bearing can be directly removed from the coupling end, saving maintenance costs. There is sufficient space reserved inside the bearing box, which can be adapted to a variety of slurry pump models, and the number of bearings can be flexibly changed according to the slurry pump head model and actual working conditions. The height of the bearing box base can be changed to adapt to a variety of slurry pump models. The base is fixed on the cement foundation with anchor bolts, and a shock absorber can be installed as required.
