Embodiment
Specific embodiment of the present utility model is illustrated below in conjunction with the accompanying drawings：
Underflow stirring is uneven to solve in the prior art for the utility model, easily blocks pipeline, underflow pump frequent start-stop,
The lost of life, the problems such as needing to be rinsed with water after termination of pumping and design.
Such as Fig. 1, shown in Fig. 2, in the fuel workshop of steam power plant, slurries caused by desulfurizer enter in concentration tower 1, reach
To after qualified density, into underflow tank 2, it is pumped into through underflow pump 3 in the device 4 of next procedure, agitating paddle is provided with underflow tank 2
5。
The utility model contributes to underflow to stir and prevent that the technical scheme of the system of line clogging from being, in underflow tank 2
Vertical baffle plate 6 is set on inwall, promotes the disturbance of slurries；
It is preferable as shown in Fig. 2 spaced set on circumferential section of the baffle plate 6 along underflow tank 2.
Change the transfer pipeline of underflow, and then improve the working method of underflow pump 3, the arrival end connection underflow of underflow pump 3
Near the tangent position of tank 2, preferably it is connected on the position concordant with agitating paddle 5, the port of export of underflow pump 3 has two pipelines,
One be access device 4 discharge nozzle, restriction orifice 8 is set on discharge nozzle, controls underflow flow, charging is set on discharge nozzle
Flow valve 9, when subsequent processing does not require charging, feed rate valve 9 is closed, and another is the refeed line 7 for returning underflow tank 2,
Refeed line 7 examines underflow tank and nearby sets returning charge flow valve 10, and underflow is flowed out by refeed line 7 after preventing parking.
