Description
Technical field
It is that one kind prevents proof submersible sand discharging pump product from blocking and fiber winding occur the utility model relates to sewage treatment field
Device.
Background technique
Proof submersible sand discharging pump is a kind of pump one and slips into the pump class product to work under liquid simultaneously, can transport sanitary wastewater,
Industrial wastewater, construction site drain and containing solid suspensions and non-corruption such as staple fiber paper scrap, sawdust, starch, silt, ore grains
Corrosion medium.Compared with general horizontal or vertical sump pump, proof submersible sand discharging pump has compact-sized, and occupied area is small, can be direct
The advantages that being installed in cesspool, saving soil and capital cost, in the row such as municipal works, Industrial Wastewater Treatment, water conservancy construction
Industry plays a very important role.Due to the use occasion of proof submersible sand discharging pump be under liquid, and convey medium mostly be containing
The mixing liquid of solid material, fibre object, the problem of product maximum is that blocking easily occurs or, by fibre object, water plant etc. at present
Winding.When being caught in bulk solid object in submersible sewage impeller of pump or enwinding impeller by fibre object, water plant etc., leaf will lead to
The operation of stuck or electromotor overload is taken turns, electric current increase very likely burns out motor, keeps dredge pump out of service.Due to diving
The use environment of dredge pump is the important events such as municipal works, water conservancy construction, and the damage of dredge pump can bring massive losses, therefore
Make proof submersible sand discharging pump anti-clogging is antiwind to be just particularly important.Previous research focuses on non-clogging impeller (such as more
ZL201310687530.3 it in design), but designs the bad performance that can sacrifice pump and can't resolve the problem of fiber is wound.
In order to make the comprehensive performance of pump reach best, the utility model proposes a kind of anti-clogging that can be used for double shrouded wheel dredge pump is anti-tangle
Winding apparatus.
Through retrieving, about proof submersible sand discharging pump anti-clogging anti-wrap device, comprehensive import sound used by the utility model
Cutter and motor replace positive and inverse control method and device automatically does not have relevant report.
Utility model content

Impeller is stuck or the problems such as wound by fibre object by solids, thus guarantee proof submersible sand discharging pump can safety operation.
In order to solve the above problem, the utility model is used disposes one and impeller in front of proof submersible sand discharging pump impeller intake
Coaxial sundries cutter, pump shaft impeller also drive the dynamic cutter of sundries cutter to rotate while rotation, it is therefore intended that
Sundries in transported medium is cut, is crushed, prevent particle it is excessive caused by clogging.It is proposed a kind of motor
Automatic positive and negative shifting method, it is therefore intended that by designing a set of automatic positive and negative rotation circuit of electromotor overload, realize when impeller is stuck
Or protection when being enwinded by fiber, prevent electromotor overload operation from causing electric current is excessively high to burn out motor.
The course of work are as follows: the fluid in pipeline is broken by import sundries cutter, adulterates sundries after being broken
Fluid enters impeller, and impeller is rotated by motor drive, and then liquid is pumped out by the pump housing.It is stifled if sundries also occurs at this time
The case where plug or winding impeller, it will lead to electromotor overload operation, electric current increases, and then by current monitoring in motor control cabinet
Instrument is monitored and is judged, and output signal shuts down proof submersible sand discharging pump and realizes that blowdown pump impeller inverts automatically after 5 seconds, instead
Turning the time reaches autostop after 3 minutes and restores rotating forward after 5 seconds.If running current or excessive, repeat again above-mentioned
Operational process.If it is still excessive to be repeated 5 times the electric current that later current monitoring instrument monitors, stopping alarm.
A possibility that the utility model is safe and reliable, and sundries cutter effectively prevents clogging and reduces winding；
Former flow field is interfered small；Sundries cutter is rotated with impeller, without providing extra power；Motor realizes automation, is not necessarily to volume
Outer labor intensive is kept an eye on, simple and convenient.
