Turn.
Sharp-tooth shaped rotor refers to being placed with multiple teeth in rotor circumferential direction, and the tip portion of each tooth is pointed tooth shape, when
When upper rotor part 2 and lower rotor part 3 operate synchronously, the tip portion of one of rotor is engaged with the root portions of another rotor,
Since the tip portion of pointed tooth shape is thinner, the tip portion of pointed tooth shape and the contact area very little of root portions, institute
To remain biggish enclosure space in 3 synchronous operation of upper rotor part 2 and lower rotor part, so that hard particulate containing high proportion is solid
The media such as body and the solid solid-liquid mixed slurry of threadiness can smoothly be transferred out by rotor, without being stuck, also not
It will lead to medium to be extruded and be crushed.
As shown in figure 9, upper rotor part 2 and lower rotor part 3 are mounted in pump chamber 4, the outer dimension of upper rotor part 2 and lower rotor part 3 with
The size of pump chamber 4 matches, so that the contact of the impeller pump tines portion of upper rotor part 2 and lower rotor part 3 and pump chamber 4 in the process of running
Area very little, pointed tooth 5 and 4 surface of pump chamber are at close vertical movement, so that the solid of hard particulate containing high proportion and fibrous solid-state
Solid-liquid mixed slurry can smoothly be transferred out by rotor.
The impeller pump of conveying solid-liquid double-phase in the utility model, sets sharp-tooth shaped for upper rotor part 2 and lower rotor part 3 and turns
Son, so that the area very little to contact with each other in 3 synchronous operation of upper rotor part 2 and lower rotor part, and remain biggish closing
Space, allow the media such as the solid of hard particulate containing high proportion and the solid solid-liquid mixed slurry of threadiness by rotor smoothly
It transfers out, and rotor will not be stuck, medium will not be caused to be extruded and be crushed.
Embodiment two
The impeller pump of conveying solid-liquid double-phase as described in embodiment one, the present embodiment is different from place and is, such as Fig. 2 institute
Show, sharp-tooth shaped rotor includes multiple pointed tooths 5, and pointed tooth 5 includes tooth top 51 and tooth root 52.
During operation, as shown in figure 3, a tooth top 51 of upper rotor part 2 is contacted with the tooth root 52 of lower rotor part 3, or on
One tooth root 52 of rotor 2 is contacted with the tooth top 51 of lower rotor part 3；Remain in operation, when one of rotor tooth top 51 be about to
When the tooth root 52 of another rotor is detached from, when to be ready being detached from the tooth root 52 of lower rotor part 3 such as the tooth top 51 of upper rotor part 2, upper rotor part 2
On the tooth root 52 of another pointed tooth 5 can be contacted with the tooth top 51 on lower rotor part 3.This impeller pump is in upper rotor part 2 and lower rotor part 3
Engagement (contact) at least one is remained in operation process, realizes the conveying of medium, and medium will not be grinded up, and be had
Manufacturing cost is low, conveys continuous and stable, long service life, feature easy to maintenance.
The impeller pump of conveying solid-liquid double-phase in the utility model, has sharp-tooth shaped rotor, which does not lean on
Engagement, but be driven by synchronous pointed tooth 5, pointed tooth 5 forms closing chamber work by tooth top 51 and tooth root 52, and tooth top 51 and tooth root 52 are
By tangentially sliding, particulate material can be hung up in this way, and the molded line that theoretic synchronous pointed tooth 5 engages is straight line cycloid, can be smoothly defeated
