Abstract
The utility model discloses a ceramic slurry pump provided with a sheath with self-balanced internal and external pressure. The ceramic slurry pump comprises a bearing assembly and a slurry pump body. The bearing assembly and the slurry pump body are coaxially mounted on a bracket which is arranged at the bottom part of the bearing assembly. The slurry pump body comprises a pump body and a pump cover. A sealing gasket I is arranged at the joint of the pump body and the pump cover. The periphery, the front side and the rear side of an impeller in the pump body and the pump cover are correspondingly provided with the sheath, a front guard board and a rear guard board. The sheath, the front guard board and the rear guard board form a closed cavity A. An airtight cavity B is formed among the sheath, the front guard board, the rear guard board, the pump body and the pump cover. A balance hole is further formed in an outlet of the sheath and communicated with the cavity A and the cavity B. The ceramic slurry pump provided with the sheath with the self-balanced internal and external pressure overcomes the shortcomings of an existing ceramic slurry pump, effectively avoids the phenomenon that over high pressure causes fractures of a ceramic sheath, and has extensive popularization and application value.

The utility model solves the technological scheme that its technical problem adopts: a kind of ceramic slag and stuff pump of sheath external and internal pressure self balancing, comprise bearing unit and slag stock pump body, described bearing unit and slag stock pump body are coaxially installed on the bracket of bearing unit bottom setting, it is characterized in that, described slag stock pump body comprises the pump housing and pump cover, the described pump housing and pump cover joint are provided with one deck sealing gasket I, in the described pump housing and pump cover, surrounding and both sides, the front and back correspondence of impeller are provided with sheath, apron plate and rear backplate, described sheath, apron plate and rear backplate form the A cavity of sealing jointly, described sheath, between apron plate and rear backplate and the pump housing and pump cover, form an airtight B cavity, between described apron plate and rear backplate and the pump housing and pump cover, by O type circle, be tightly connected, the outlet port of described slag stock pump body arranges exit cone, described exit cone and the pump housing, between pump cover, by O type circle, be tightly connected, the inlet of described slag stock pump body arranges import Taper Pipe, described import Taper Pipe and the import of pump cover and the import of apron plate are tightly connected by sealing gasket II, described sheath outlet port is also provided with an equalizing orifice, described equalizing orifice is communicated with A cavity and B cavity.
The sealing gasket II arranging between described import Taper Pipe and the import of pump cover and the import of apron plate is rubber gasket.
The inner impeller arranging of the described pump housing and pump cover is ceramic impeller.
The sheath of the A cavity of described formation sealing is ceramic sheath, and apron plate is ceramic apron plate, and rear backplate is backplate after pottery.
The beneficial effects of the utility model are: the ceramic slag and stuff pump of a kind of sheath external and internal pressure of the utility model self balancing has overcome the deficiency of existing ceramic slag and stuff pump, guaranteed ceramic slag and stuff pump body interior pressure equilibrium of forces, the fracture of effectively having avoided ceramic sheath to cause because pressure is excessive, greatly expand the Applicable scope of ceramic slag and stuff pump, there is application value widely.

Embodiment
For clearly demonstrating the technical characterstic of this programme, below by an embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
As shown in Figure 1 and Figure 2, the ceramic slag and stuff pump of a kind of sheath external and internal pressure of the utility model self balancing, comprises bearing unit 1 and slag stock pump body 2, and described bearing unit 1 and slag stock pump body 2 are coaxially installed on the bracket 3 of bearing unit 1 bottom setting.
Described slag stock pump body 2 comprises the pump housing 21 and pump cover 22, pump cover 22 is covered on the pump housing 21, the described pump housing 21 is provided with one deck sealing gasket I 4 with pump cover 22 joints, the surrounding of the described pump housing 21 and the interior impeller 5 of pump cover 22 and both sides, front and back correspondence are provided with sheath 6, apron plate 7 and rear backplate 8, described sheath 6, apron plate 7 and the common A cavity 9 that forms sealing of rear backplate 8, described sheath 6, between apron plate 7 and rear backplate 8 and the pump housing 21 and pump cover 22, form an airtight B cavity 10, between described apron plate 7 and rear backplate 8 and the pump housing 21 and pump cover 22, by O type circle 11, be tightly connected, the outlet port of described slag stock pump body 2 arranges exit cone 12, described exit cone 12 and the pump housing 21, between pump cover 22, by O type circle 11, be tightly connected, the inlet of described slag stock pump body 2 arranges import Taper Pipe 13, described import Taper Pipe 13 is tightly connected by sealing gasket II 14 with the import of pump cover 22 and the import of apron plate 7, the sealing gasket II 14 arranging between the import of described import Taper Pipe 13 and pump cover 22 and the import of apron plate 7 is rubber gasket.
The outlet port of described sheath 6 is also provided with an equalizing orifice 15, and equalizing orifice 15 is communicated with A cavity 9 and B cavity 10.Can make like this pressure in A cavity 9 and B cavity 10 keep balance, when A cavity inside pressure increases, sheath can not rupture because pressure is excessive yet, has effectively avoided because sheath 6 bearing capacities are not enough, and the problem that fracture occurs sheath 6 occurs.
The described pump housing 21 and the inner impeller 5 arranging of pump cover 22 are ceramic impeller, and the sheath 6 of the A cavity 9 of described formation sealing is ceramic sheath, and apron plate 7 is ceramic apron plate, and rear backplate 8 is backplate after pottery.Inner impeller 5, sheath 6, apron plate 7, the rear backplate 8 arranging of slag stock pump body 2 all adopts stupalith, due to corrosion-resistant, wear-resistant, is suitable for using under the operating mode of ore dressing, smelting etc. complexity.
The inside of ceramic slag and stuff pump body 2 of the present utility model arranges two cavitys, between two cavitys, equalizing orifice is set, when ceramic slag and stuff pump moves, A cavity 9 and B cavity 10 pressure can keep a kind of state of relative equilibrium all the time, when slag stock pump body 2 internal pressures increase, due to the effect of equalizing orifice 15, A cavity 9 external and internal pressure relative equilibriums, thereby guarantee that sheath 6 can not rupture too greatly because external and internal pressure is poor, effectively widened the using scope of ceramic slag and stuff pump.
Except the technical characteristics described in above-mentioned specification, be the known technology of those skilled in the art.
