Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1 to 3, in the first embodiment, a flexible structure slurry pump includes a pump body, a front guard plate, a rear guard plate and an impeller;

the contact position of the pump body 1 and preceding backplate 3 and backplate 4, the last lower extreme packing of the body of preceding backplate 3 and backplate 4 has flexible thing 8, impeller 5's left end intermediate position fixed mounting has the pivot, the surface movable sleeve of pivot is equipped with axle sleeve 7, axle sleeve 7 and backplate 4 contact position packing have flexible thing 8, flexible thing 8 is when flexible structure pulp pump is installed, guarantee the pump body 1, the marginal gap of preceding backplate 3 and backplate 4 can not be at the outside mud of infiltration, cause the part wearing and tearing, simultaneously flexible structure pulp pump is when using, flexible thing 8 guarantees that the part can not lead to the condition that the part appears wearing and tearing because of the vibration that the operation is.

The outer wall fixed mounting of impeller 5 has bull stick 63, bull stick 63 extends to the water inlet of the pump body 1, water inlet department of the pump body 1 is provided with filter layer 61, filter layer 61 can get rid of outside solid debris outside the device when using, prevent that solid debris from getting into organism 1 inside, cause the damage of part, bull stick 63 runs through the outer wall of filter layer 61, extend to inside the filter layer 61, the intermediate position of filter layer 61 inner chamber places solid fixed ring 62, bull stick 63 activity cup joints in the centre of solid fixed ring 62, bull stick 63 fixed mounting has runner 64 on one section outer wall of pump body 1 inside, bull stick 63 is rotatory when impeller 5, can synchronous revolution thereupon, thereby drive runner 64 and rotate, form centrifugal force in order to import at organism 1, the efficiency that supplementary outside thick liquid passes through.

The lower end of the rotating blade 65 is fixedly provided with a lower fan blade 652 on the outer wall of the rotating rod 64, the inner cavity of the lower fan blade 652 is hollow, the inner cavity of the lower fan blade 652 is movably sleeved with an upper fan blade 651, the bottom of the inner cavity of the lower fan blade 652 is fixedly provided with a spring 653, and when the centrifugal force is greater than the elastic force of the spring 653, the upper fan blade 651 extends to the outer end of the upper part of the lower fan blade 652 so as to increase the peripheral vortex of the rotating blade 65 and ensure that external slurry can enter the interior of the slurry pump more quickly.

The area of the top opening cross section of the lower fan blade 652 is smaller than the area of the bottom cross section of the upper fan blade 651, and when the rotating rod 64 rotates to drive the rotating blade 65 to rotate, the upper fan blade 651 moves upward, and the upper fan blade 651 cannot be separated from the top cavity of the lower fan blade 652.

The spring 653 keeps the upper blades 651 in the cavity of the lower blades 652, and when the efficiency of external slurry passing through the impeller is not high and the rotating blade 65 cannot form a large vortex at the water inlet of the pump body, the upper blades 651 cannot leave the cavity of the lower blades 652, so that the rotating force required by the rotating rod 65 is reduced, and the efficiency of the impeller 5 is ensured.

The pump body 1 is connected with the front guard plate 3 and the pump body 1 is connected with the rear guard plate 4 through the connecting bodies 2, so that the overall firmness is ensured.
