Description

Automatic medicine adding apparatus and its backwash filter

Technical field

The utility model is related to filter, more specifically, it relates to a kind of automatic medicine adding apparatus and its backwash filter Device.

Background technology

Backwash filter, is a kind of impurity that utilization filter screen is directly intercepted in water, removal water body recovery technology, particulate matter, Reduce turbidity, purify water, reduce system dirt, bacterium algae, corrosion etc. and produce, with purify water and protection system other equipment just The precision equipment for often working；Backwash filter is often added to filter mixing liquid in medicine machine, by filtering Impurity, the dregs of a decoction are removed so that solvent clean ability is more outstanding.

Traditional backwash filter structure is complex, and volume is also relatively bulky, in actual use, is unfavorable for The dismounting and change of filter core, safeguards and also not enough facilitate.Medicine is added in medicine machine may not fully be dissolved, and form the dregs of a decoction, Solution there may be impurity effect cleaning performance；Regarding to the issue above, notification number is disclosed for the Chinese patent of CN203425590U A kind of portable backwash filter, including straight barrel type filter cylinder and rearmounted element kit, rearmounted element kit are arranged concentrically on In straight barrel type filter cylinder, there is first annular runner between rearmounted element kit and straight barrel type filter cylinder, the front end of straight barrel type filter cylinder sets Water inlet pipe is equipped with, preposition element kit is provided with water inlet pipe, water inlet pipe is provided with the second annular channel with preposition element kit, The first valve, phase between first annular runner and the second annular channel are provided between rearmounted element kit and preposition element kit Logical, the rear end of straight barrel type filter cylinder is provided with outlet pipe, and outlet pipe is communicated with the second annular channel, and the rear end of rearmounted element kit sets Blow-off pipe is equipped with, the second valve is provided with blow-off pipe.

Under in working order, the first valve is opened and the second valve closing, and liquid is rearmounted by being flowed in preposition element kit In element kit, the liquid in rearmounted element kit is entered into outlet pipe by first annular runner；Under backwash state, First valve closing and the second valve opening, liquid flow through preposition element kit and enter into the second annular channel, the second annular flow Liquid in road is entered back into rearmounted element kit, and the liquid in rearmounted element kit is discharged by blow-off pipe；Above-mentioned patent In backwash filter it is although portable, but after residue is drained into blow-off pipe in backwash process, it is impossible to collect impurity, medicine Slag etc. understands solution purity with this carries out the change of production strategy, and will rinse the part solution of residue to waste.

Utility model content

In view of the shortcomings of the prior art, the purpose of this utility model one is to provide a kind of reduction blowdown to waste molten The backwash filter of liquid resource.

To achieve the above object, the utility model provides following technical scheme：

A kind of backwash filter, including cylinder, the filter element for automatic fitration solution and play throttling and return The reflux unit of adduction, the filter element include one end and the upper filter, one end that the inlet of cylinder is slidably connected with it is upper The lower filter that the automatic fitration component of the other end connection of filter core and one end are connected with the automatic fitration component other end, described time Stream unit includes the return duct being sequentially connected, reclaims component, blow-off pipe, and the return duct is connected with the inlet of cylinder, described Blow-off pipe is connected with the other end of lower filter.
