At impeller 3 pivoted in-process, the bearing can receive the friction, need regularly clean one side of 5 non-promotion fluids of blade on the impeller 3 in order to avoid the excessive friction of bearing to avoid the adhesion to pile up too much residue on the blade 5, guarantee impeller 3's mass distribution homogeneity, and then reduce and slow down the wearing and tearing that impeller 3 rotates the in-process and cause the extrusion of bearing unilateral.

The rotating shaft of the motor 1 extends into the pump shell 2, the impeller 3 comprises a disk body 4 coaxially fixed on the rotating shaft, at least more than 3 blades 5 are circumferentially installed on one side of the disk body 4 at intervals, each blade 5 is in a long plate shape, a shaft groove 51 is preset at one end, far away from the disk body 4, of each blade 5, each shaft groove 51 extends along the axis direction of the disk body 4, a shaft rod 52 is rotatably inserted in each shaft groove 51, a reset torsion spring 53 sleeved on the shaft rod 52 is further arranged in each shaft groove 51, one end of each reset torsion spring 53 is fixed with the shaft rod 52, the other end of each reset torsion spring is fixed with the corresponding blade 5, a locking structure detachably connected with the center of the disk body 4 is arranged at the other end of each blade 5, meanwhile, an installation opening 21 is formed in the lower side of the pump shell 2, an opening plate 6 is hinged to the installation opening 21, and a hairbrush 61 is installed on the lower side of the opening plate 6;

when the doctor solution is pumped normally, the opening plate 6 seals the mounting opening 21, and the brush 61 is positioned outside the pump shell 2, so that the impeller 3 can effectively push the doctor solution to accelerate output;

when the desulfurization pump operates for a certain time, the locking structure of the blade 5 is unlocked, the reset torsion spring 53 still enables the blade 5 to be abutted to the hollow shaft cylinder 41 coaxially extending from the center of the disc body 4, then the opening plate 6 is unlocked and rotates towards the pump shell 2, the brush 61 faces the impeller 3, the motor 1 is started again, the impeller 3 rotates, a rotation angle limiting structure is arranged between the shaft groove 51 of the blade 5 and the shaft rod 52, the blade 5 rotates to be tangent to the disc body 4 due to centrifugal force, the brush 61 rubs with the blade 5 in the continuous rotation process of the impeller 3, solidified particles on the blade 5 are swept down, excessive particles are prevented from being adhered to the blade 5, the weight of the impeller 3 is reduced, the eccentric abrasion of a bearing is reduced, and the service life of the desulfurization pump is prolonged.

Wherein the locking structure includes that circumference interval sets up the bayonet socket 42 on hollow shaft 41, it has the rectangular form abaculus 54 to extend perpendicularly on blade 5, the movable business turn over bayonet socket 42 of abaculus 54, the mounting groove has been seted up towards hollow shaft 41 one side at abaculus 54, be provided with locking spring 55 and fixture block 56 in the mounting groove, after in the bayonet socket 42 is stretched into to abaculus 54, locking spring 55 partially releases the mounting groove with fixture block 56, make fixture block 56 and the butt of the 41 inner wall of hollow shaft, realize the fixed of blade 5 on disk body 4.

In addition, a sliding groove is formed in the pump shell 2 and located on the axis of the hollow shaft cylinder 41, a control pin 7 is installed in the sliding groove, the control pin 7 can move in and out of the hollow shaft cylinder 41, the control pin 7 pushes the fixture block 56 into the installation groove, when the fixture block 56 enters the installation groove, the fixture block 56 and the insert block 54 form a complete guide inclined plane 57 towards one side of the control pin 7, at the moment, the control pin 7 is abutted against the guide inclined plane 57, further, the control pin 7 pushes the insert block 54 outwards of the bayonet 42 by pushing the control pin 7 until the insert block 54 is abutted against the outer circular ring surface of the control pin 7, the synchronous fixture block 56 also moves outwards of the bayonet 42, and part of the fixture block 56 extends out of the bayonet 42, at the moment, the locking spring 55 pushes the inclined plane on the fixture block 56 to be abutted against the edge of the bayonet 42, and when no other power pushes the blade 5, the reset torsion spring 53 cannot enable the fixture block 56 to pass through the bayonet 42, so that the purpose of unlocking the blade 5 is achieved;

after the blades 5 are cleaned, the impeller 3 stops rotating, the return torsion spring 53 drives the blades 5 to rebound and rotate, and under the action of the kinetic energy of the blades 5 and the return torsion spring 53, the clamping block 56 locks the blades 5 through the bayonet 42, so that the blades 5 are unlocked and locked without disassembling the pump shell 2 by controlling the movement of the control pin 7 and controlling the rotation of the impeller 3, and the blades 5 are cleaned conveniently.

In addition, a baffle ring 71 is coaxially fixed at the outer end of the control pin 7 positioned on the pump shell 2, a sealing ring 72 is coaxially fixed at the part of the control pin 7 positioned on the pump shell 2, a return spring 74 is sleeved on the control pin 7 at the outer side of the pump shell 2, two ends of the return spring 74 are respectively abutted against the baffle ring 71 and the outer side of the pump shell 2, a ring groove is preset at the inner side of the pump shell 2 opposite to the sealing ring 72, an elastic sealing ring 73 is coaxially attached to the sealing ring 72, the return spring 74 pushes the baffle ring 71 until the elastic sealing ring 73 on the sealing ring 72 is extruded and embedded in the ring groove, so that the sealing problem of the pump shell 2 is effectively solved, and the stability of pumping the desulfurization solution is ensured.

And wherein set up as the spherical structure on the side of the impeller 3 of seal ring 72, when the high rotation of impeller 3 pumps the doctor solution, the flow of doctor solution collides with seal ring 72, and the spherical structure on the seal ring 72 has effectually reduced the flow resistance of doctor solution to can make the doctor solution to the impact force of seal ring 72 and the effort direction of reset torsion spring 53 to retainer ring 71 the same, further promote the sealing reliability of elasticity sealing washer 73.

Because the brush 61 can descend and can be crooked after using at every turn, so set up the slide at the one side of split plate 6 outside towards pump case 2, the slide extends along the axis direction of impeller 3 and sets up, and brush 61 includes brush board 611 and brush hair 612, and brush board 611 can be dismantled and pegged graft in the slide, through dismouting brush 61 to guarantee the cleaning reliability to blade 5 at every turn.

The working principle of the invention is as follows:

the pumping process comprises the following steps:

the motor 1 is started, the impeller 3 rotates, and the blades 5 drive the desulfurization solution to accelerate, so that the desulfurization solution is pumped.

Cleaning the blade 5:

unlocking the opening plate 6, pushing the opening plate 6 to rotate towards the pump shell 2, further enabling the brush 61 to face the blade 5, then pushing the retaining ring 71, enabling the control pin 7 to extend into the hollow shaft cylinder 41, unlocking the locking of the blade 5, starting the motor 1 again, enabling the impeller 3 to rapidly rotate, enabling the blade 5 to rotate under the action of centrifugal force, and enabling the synchronous blade 5 and the brush 61 to be in contact and friction, thereby scraping condensed solid particles on the blade 5, further avoiding excessive abrasion of a bearing and reducing the load of the motor 1;

after the motor 1 stops, the blade 5 rotates towards the center of the disc body 4 under the action of the return torsion spring 53, and the embedded block 54 and the clamping block 56 enter the bayonet 42 again to realize the locking of the blade 5.
