Specific implementation mode
The utility model proposes a kind of filler transfer system, the advantages of in order to make the utility model, technical solution more
It is clear, clear, it elaborates to the utility model with reference to specific embodiment.
The utility model filler transfer system, including the pump housing, feed separation mechanism and actuating unit, wherein as this reality
With novel main improvement, the perfect cooperation of the pump housing and feed separation mechanism keeps filler, it can be achieved that transfer to filler
Integrality.As shown in Figure 1, the pump housing includes pump case 1, pump case 1 is made of concrete structure vertical section, curved section and oblique section,
In, vertical section is stretched into filler, and for curved section between vertical section and oblique section, vertical section of bottom is filler feed inlet, filler
Feed inlet be it is horn-like, i.e.,：It is charging horn mouth 3 at charging, conducive to coming into full contact with for feed inlet and filler, contact area ratio
Common feed throat area is big, facilitates the transfer of filler.
Why using curved section, oblique line section transition, predominantly ensure that filler can smoothly change direction in the duct, prevent
Only filler blocks or larger local pressure causes to damage to filler.
Oblique section of the pump housing connect with the material conduit 4 of material mechanism, and oblique section of the pump housing, curved section and vertical section are
Cylindricality, and its diameter >=600mm, the pump case 1 of major diameter can be blocked to avoid filler.
The pump housing further includes pump shaft 11, guide vane 12 and impeller 13, and pump shaft 11 is arranged along the axial line of pump case, bottommost
The vertical section of lowermost end away from pump case has a distance, top to be pierced by the curved section of pump case, passes through sealing structure 2 at the place of being pierced by
It is sealed, the place's of being pierced by connection shaft coupling 10,10 connecting power device 9 of shaft coupling, if the utility model is preferably electro-motor,
Intermediate in material conduit 4 to be equipped with separating screen 5, one end of material conduit is connected as oblique section of feed inlet and pump case, separately
One end place opposite with feed inlet is that filler exports 6, and separating screen 5 time is header tank 7, header tank bottom setting outlet conduit 8.
The utility model impeller 13 is equipped with 2 or 3 blades, and curve form, blade upstream face are twisted into along radiation direction
Outer edge is 18~75 ° with direction of motion plane corner cut, that is to say, that it has certain angle with the direction of motion, designs in this way,
Upon the rotation of the blade, filler can be struck to avoid blade forward direction, causes filler broken, keeps the integrality of filler.Practical behaviour
It is found in work, when blade upstream face outer edge is less than 18 ° with direction of motion plane corner cut, can not ensure the integrality of filler；
Blade ensures the void space in the pump housing, filler is avoided to block no more than 3 simultaneously.
It is preferred that guide vane is equipped with 3~6 blades, it is uniformly distributed in a circumferential direction, 5 eye diameter of preferable separate sieve is little
In filler ruler diameter, present case is preferably 5~20mm.By the void space in increasing pump body, increase outside impeller blade upstream face
Edge and direction of motion plane corner cut, are arranged separating screen, can quickly shift filler, and ensure the integrality of filler.
Why impeller and guide vane are set, and main cause is that the mixed liquor with rotary motion flowed out from impeller is become
For axial flowing, the kinetic energy of a part of flow is become pressure energy, reduces filler high velocity impact.
The operational process of above-mentioned filler transfer system, includes the following steps：
The first, the system is installed in place, vertical section of pump case is stretched into packing area to be transferred, turn on the power dress
It sets, at this point, shaft coupling rotates, pump shaft 11 is driven to rotate, guide vane and impeller on pump shaft start to rotate, and filler enters pump case
It is interior；
The second, filler enters oblique section through vertical section, curved section, out of oblique section of entrance material conduit connected to it,
In material conduit under the action of sieve, the water entered together with filler enters in header tank, and filler filling out from material conduit
Material outlet output, into the water in header tank, enters biochemistry pool through outlet conduit, can efficiently separate filler and water, realizes
The enrichment of filler is shifted.
