It should be noted that like reference numerals and letters refer to like items in the following figures, and thus, once an item is defined or illustrated in one figure, it will not need to be further discussed or illustrated in detail in the description of the following figure.

As shown in fig. 1-3, the present invention provides a technical solution: the utility model provides a sediment stuff pump impeller structure that silica sand washing selected system used, includes actuating mechanism 2, actuating mechanism 2 includes sealed motor cabin 201, and the inside fixed mounting in sealed motor cabin 201 has driving motor 202, it needs to be noted that, the function of this embodiment is the rivers that suction, transportation contain silica sand, consequently whole mechanism need often contact the water, consequently the leakproofness of sealed motor cabin 201 will be guaranteed, prevent to have or carry out the operation under water, driving motor 202 intake the short circuit, cause the trouble. Meanwhile, the power supply system of the driving motor 202 is specially designed, so that the water body is prevented from leaking into the sealed motor cabin 201, and the electric leakage of the cable in water is prevented, so that the life safety of workers is threatened. Sealed motor cabin 201 one end fixedly connected with paddle room 1, including integral type shaft 102 in the paddle room 1, and driving motor 202 output and this integral type shaft 102 swing joint, in this embodiment, integral type shaft 102 is like a disc, and the edge is provided with the smooth plastic cover that makes things convenient for the pivoted, cuts off paddle room 1 almost completely. And the rear side of the integrated wheel shaft 102 is provided with a bearing sleeve for connecting with the output end of the driving motor 202. When the slurry pump works, slurry is poured into the blade chamber 1, and if solid components in the slurry are sucked into the integrated wheel shaft 102, the solid components are difficult to take out, and the bearing sleeve is likely to be damaged in stirring, so that the slurry pump is damaged. Therefore, the disc-shaped integrated wheel shaft 102 is arranged, so that only water can flow into the rear side of the wheel shaft during work, and the bearing is protected.

Integral type shaft 102 one end fixedly connected with slurry pumping paddle 101, slurry pumping paddle 101 one end fixedly connected with paddle protective housing 109, in this embodiment, slurry pumping paddle 101 snap-on is on integral type shaft 102's surface, and consequently numerous paddle bottom do not need interconnect to certain space has been left, can not direct impact slurry pumping paddle 101 when making the sediment thick liquid pour into through this piece space. The paddle protective housing 109 is composed of an upper piece and a lower piece, and the slurry pumping paddle 101 is sandwiched in the middle and can rotate along with the rotation of the paddle, so that the protective effect on the slurry pumping paddle 101 is achieved. One end of the blade protecting shell 109 is fixedly connected with a separate guard plate 110, in this embodiment, the separate guard plate 110 can be spliced into a disk with an opening in the middle, and the disk is arranged according to the number of the slurry pumping blades 101 and is fixedly connected with the blade protecting shell 109 on the corresponding blade. In this embodiment, the slurry pumping blade 101 needs to stir the slurry containing a large amount of silica sand, the silica sand collides with the slurry pumping blade 101 during stirring, and the blade is worn, so the blade protective shell 109 needs to be arranged, and the blade protective shell 109 is made of high-strength wear-resistant resin, and has strong corrosion resistance, impact resistance and wear resistance, and the quality is light, and the normal rotation of the slurry pumping blade 101 is not affected, when a certain blade protective shell 109 is damaged to a certain extent, the blade protective shell 109 on the blade can be taken down and replaced independently, and the maintenance cost is saved. The one end fixedly connected with slip hoop of disconnect-type backplate 110, slip hoop one end swing joint has sealed fixed hoop 104, it should be noted that, the sliding tray has been seted up to sealed fixed hoop 104 front end, and the slip hoop phase-match for disconnect-type backplate 110 can slide smoothly on sealed fixed hoop 104, and sealed fixed hoop 104 and disconnect-type backplate 110 cooperate, has hindered the flow of sediment thick liquid equally, makes it can only flow into among the paddle through the opening in disconnect-type backplate 110 center. A middle wall 108 is fixedly connected to the outside of the sealing and fixing band 104. One end of the middle wall 108 is fixedly connected with the rear end ring wall 107, one end of the rear end ring wall 107 is fixedly connected with the isolation base plate 106, and the blade chamber 1 and the sealing motor cabin 201 are separated through the isolation base plate 106, so that the slurry is prevented from flowing backwards and damaging the driving motor 202. The other end of the middle wall 108 is fixedly connected to a blade cap 111. One end of the blade top cover 111 is fixedly connected with a slurry inlet pipe 112, and the slurry inlet pipe 112 is communicated to the other side of the blade top cover 111. The top end of the middle wall 108 is fixedly connected with a pulp outlet pipe 103, and the pulp outlet pipe 103 is communicated to the inside of the middle wall 108. When the equipment is used, the slurry is firstly poured into the blade chamber 1 in a natural inflow mode, then the driving motor 202 drives the slurry pumping blade 101 to rotate, centrifugal force is generated, the surrounding water body is thrown outwards and obtains extremely high speed, and therefore the slurry flows out through the slurry outlet pipe 103; after the slurry flows out, partial cavities are formed in the blade chamber 1 to generate negative pressure, so that external slurry is continuously pumped into the blade chamber 1 and is led out through the slurry outlet pipe 103.

A sealing rubber pad layer 105 is fixedly connected to the inner side of the middle wall 108, one end of the sealing rubber pad layer 105 is fixedly connected with the sealing fixing hoop 104, and the other end of the sealing rubber pad layer 105 is fixedly connected with the isolation bottom plate 106. These are all for improving the leakproofness of blade chamber 1, make the vacuum environment more easily produce in blade chamber 1, and prevent the sediment thick liquid leakage two.

When using this to use when novel, the staff will inspect at first whether each disconnect-type backplate 110 and paddle protective housing 109 state are good, whether sealed rubber cushion layer 105 has the damaged condition, disconnect-type backplate 110, sealed rubber cushion layer 105 and sealed fixed hoop 104 are connected whether inseparably, in the sediment thick liquid is submerged to the sediment thick liquid pump in the follow-up, it goes into among the thick liquid pipe 112 to submerge the sediment thick liquid at least, opens driving motor 202 afterwards, drives and takes out thick liquid paddle 101 and take out the sediment thick liquid from play thick liquid pipe 103.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
