Description
Technical field
The utility model relates to the technical field of sewage pump configuration, especially a kind of outer knife rotating cutting type sewage pump.
Background technique
Dredge pump has the characteristics that can transport the liquid containing rigid solid, fibre object and the substances such as dirty, viscous, sliding, and
It is widely used in mine, papermaking, printing and dyeing, environmental protection, oil refining, petroleum, chemical industry, farm, dyeization, wine brewing, food, chemical fertilizer, mud
In the sewage treatments of numerous industries such as slurry, drift sand, mire, the dirty pool.
In Chinese patent, a kind of novel residue discharge pump is disclosed in Patent No. 2017201651920, it includes pump case 1, suitable
Secondary blade holder 2, pedestal 11 and the chopping disk 3 for being connected to 1 lower section of pump case is sequentially fixed through pump case 1, blade from top to bottom
The pump shaft 4 of frame 2, water outlet 5 is provided on the pump case 1, and the rotation of pump shaft 4 is installed on pump case 1, pacifies on pump shaft 4
Equipped with the impeller 6 being located in pump case 1, extends and blade 7 is installed on the pump shaft 4 outside chopping disk 3, it is characterised in that: is described
Blade holder 2 in be provided with sewage runner, offered on the top surface of blade holder 2 connection sewage runner arc it is recessed
The depth of slot 8, arc groove 8 is gradually deepened from 2 outer edge of blade holder to sewage runner, is opened up on the chopping disk 3
There is the mistake water flow passage 9 of connection sewage runner, is additionally provided with multiple chip spaces 10 on the top surface of chopping disk 3, the one of chip space 10
End extends to the outer edge of chopping disk 3, and the other end was connected to water flow passage 9.
The course of work of the deslagging pump are as follows: connect prime mover with pump shaft 4, prime mover drives pump shaft 4 to rotate, 4 band of pump shaft
Movable vane wheel 6 and blade 7 rotate, and impeller 6 enters the sewage containing fiber impurity in sewage runner by water flow passage 9, are entering
During sewage runner, with chopping disk 3 relative shear occurs for high-speed rotating blade 7, is ground with carrying out cutting to fiber impurity,
Prevent the deslagging pump from blocking, and when being wound with certain thickness fiber on 7 point of a knife of blade, chip space 10 by fiber scrape and by
Chip space 10 is discharged, to ensure that the cutting power of blade；It grinds rear sewage and clast enters in pump case 1, clast is along arc
Connected in star 8 is again introduced into cutting area, is finally discharged by chip space 10, and the sewage without fibre-bearing impurity is discharged from water outlet 5, real
The discharge of fiber impurity is showed.
It can thus be appreciated that blade 7 and chopping disk 3 relative shear occurs could be by fibre cutting, but if blade 7 and cutting
After 3 friction gap of disk is gradually increased, cutting effect is caused to significantly reduce, and cuts the chopping disk that can only more renew after mill damage,
To guarantee that chopping disk 3 is contacted with slice 7, therefore chopping disk is frequently replaced, increases use cost.Therefore this deslagging pump is
It can not promote the use of, i.e., can not be carried out continuously cutting fibre.
