Grains of sand sediment may block greatly the check valve bonnet of deep well pump equipped at outlet port very much, prevent check valve from normal use, so that
Cause grains of sand sediment to enter inside deep well pump, block deep-well pump blade, prevent deep well pump in lower task from normally starting,
Even damage deep well pump.
Utility model content
The utility model is in order to solve the problems of the prior art, there is provided a kind of anti-long-pending sand device of deep well pump, reduces husky
Grain sediment enters inside deep well pump, avoids accumulating sand and blocks deep-well pump blade, so as to improve the operating efficiency of pump, reduces inspection
Accomplish this.
In order to solve the above technical problems, the utility model adopts the following technical scheme that：The anti-long-pending sand device of deep well pump, including
The vertical duct being connected with pump housing delivery outlet, the vertical duct are docked successively by upper duct section, middle duct section and lower duct section
Composition, and the upper end of middle duct section and the joint of upper duct section and the lower end of middle duct section and the joint of lower duct section are equal
It is fixedly connected by the way that ring flange is detachable；The dividing plate with limbers is fixed with the middle duct section, is provided with the upside of dividing plate
Matched sand block plate, the inwall upset of sand block plate and middle duct section connect, and positioned at the upper of sand block plate in middle duct section
Limited block is provided with side, limited block is fixed on the inwall of middle duct section, when sand block plate is overturn and is abutted with limited block, sand block
Angle between plate and dividing plate is more than 45 ° and less than 90 °.
When sand block plate is overturn and is abutted with limited block, the angle between sand block plate and dividing plate is 60 °.
The limited block is the chondritic for protruding from middle duct section inwall.
The limbers uniform spread configuration on dividing plate.
The beneficial effects of the utility model：
Vertical duct is divided into the upper duct section docked successively, middle duct section and lower duct section by the utility model, and in
Dividing plate and sand block plate are added at duct section, when deep-well pump work, water is by the limbers on dividing plate and drives sand block plate upward
Upset, until sand block plate abuts with limited block, now vertical duct is kept unimpeded；When deep well pump is stopped, sand block plate exists
Downwardly turn under self gravitation effect and abutted with dividing plate, now vertical duct is ended at middle duct section, in vertical duct
Grains of sand sediment can sink to being deposited on sand block plate, when deep well pump works again, product sand discharged under current scour, so as to
Reduce grains of sand sediments to enter inside deep well pump, avoid accumulating sand and block deep-well pump blade, so as to improve the operating efficiency of pump, subtract
The cost of overhaul is lacked.
Also, the upper end due to middle duct section and the joint of upper duct section and the lower end of middle duct section and lower duct section
Equal joint is fixedly connected by the way that ring flange is detachable, can be by middle duct section for the preferable operating environment of water quality
Take away, upper duct section and lower duct section are directly docked.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
The view of sand block plate when Fig. 2 is deep-well pump work；
Fig. 3 is the view of sand block plate when deep well pump is stopped.
Embodiment
Specific embodiment of the present utility model is elaborated below in conjunction with accompanying drawing.
As shown in Figure 1 to Figure 3, the anti-long-pending sand device of deep well pump of the present utility model, including be connected with the delivery outlet of the pump housing 1
Vertical duct, the vertical duct is docked and formed successively by upper duct section 21, middle duct section 22 and lower duct section 23, and middle pipeline
The upper end of section 22 passes through with the joint of upper duct section 21 and the lower end of middle duct section 22 and the joint of lower duct section 23
Ring flange is detachable to be fixedly connected.
The dividing plate 3 with limbers, limbers uniform spread configuration on dividing plate 3 are fixed with the middle duct section 22.
The upside of dividing plate 3 is provided with matched sand block plate 4, and the inwall upset of sand block plate 4 and middle duct section 22 connects, and middle duct section
Limited block 5 is provided with the top of sand block plate 4 in 22, limited block 5 is fixed on the inwall of middle duct section 22, when sand block plate 4
