Enter the filter in neck, and be provided with filter hole on filter, is provided on filter grid one-to-one with the filter hole
Dredging thorn, is provided with elastic component between filter and filter grid.
Preferably, the material, which enters the side wall of neck and is located above filter, is provided with cleaning solution import,
Rinse liquid outlet is provided on the downside of screw pump ontology.
Preferably, coupling rod left end is connect by left universal joint with speed reducer, and speed reducer passes through output shaft and motor
Connection.
Preferably, the filter hole is arranged in multiple concentric, and at N circle, and the number of filter hole is 2^N,
The arrangement mode of corresponding dredging thorn is also identical as filter hole, and the filter grid includes the ring of multiple concentric and by multi-turn institute
The connection strap that ring connects is stated, the dredging thorn is located on ring described in multi-turn.
Compared with the prior art,
1, material, which will first pass through material is arranged in enter the filter of neck and then pass through, enters screw pump after filter grid
Ontology, will be less so that the material for flowing into screw pump ontology is impure, it is not easy to impurities accumulation occur in screw pump ontology and lead
The problem of causing coupling rod damage；
2, the impurity after using one end time on filter will be accumulated, so that material inflow is influenced, it at this time can be with
Motor is closed, material will not be inhaled into screw pump ontology at this time, then pour into cleaning solution, cleaning solution by filter washing water inlet
The filter decline for having accumulated impurity will be being pressed against, the dredging thorn on filter grid passes through filter hole, so that filter is dredged,
Impurity is punched into screw pump ontology simultaneously, and is flowed out by rinse liquid outlet, is not only realized during this to filtering
The cleaning of piece, while the component of screw pump body interior has also been cleaned, further reduced coupling rod will not accumulate asking for impurity
Topic.

Specific embodiment
It is described in further detail with reference to the accompanying drawing and by specific embodiment to utility model, following embodiment only describes
Property, it is not restrictive the protection scope of the utility model.
Embodiment
A kind of single-screw (single screw) pump is provided with connecting shaft dry 2, connecting shaft referring to attached drawing 1-5, including screw pump ontology 1 in ontology
Both ends be respectively arranged with the first universal joint 31 and the second universal joint 32, the both sides external of screw pump ontology 1 is respectively arranged with electricity
Machine 6 and stator 4 are provided with rotor 5 in stator 4, and rotor 5 is connect by the first universal joint 31 with connecting shaft dry 2, and motor 6 passes through and subtracts
Fast machine 61 and the second universal joint 32 driving connecting shaft dry 2.Stator is using material production corrosion-resistant, resistant to high temperature.
Wherein, it is provided with material on screw pump ontology 1 and enters neck 11, such as petroleum, enter from material inlet 111, and
Enter on neck 11 in material and be provided with filter mechanism, filter mechanism includes the filter plate for entering the up and down connection of neck 11 with material
7 and fixed filter grid 8, the filter hole 71 of multiple concentric is provided on filter plate 7, and at N circle, of filter hole 71
Number is 2^N, and defining the position in the center of circle is the 0th circle.Filter grid 8 include multiple concentric be arranged and with filter hole 71
One-to-one dredging thorn 83 is set, dredging thorn 83 is fixed on the ring 81 of multiple concentric, and ring 81 is solid by connection strap 82
It is fixed integral.
In this way, when motor 6 drive rotor 5 rotate when, petroleum will be entered entrances by material, by filter mechanism later again into
Enter into screw pump ontology 1, then be discharged by output end.During this, the impurity in petroleum will be filtered the filtering of plate 7, flow into
Petroleum cleanliness in screw pump ontology 1 is very high, it is not easy to which impurities accumulation occur in screw pump ontology 1 causes coupling rod to damage
Bad problem.And when the impurity on filter plate 7 is too many so that when filter hole 71 is blocked, filter plate 7 will be pressed down, spring
9 compressions store power, while filter hole 71 will be passed through by dredging thorn 83, and filter hole 71 is dredged, meanwhile, the surface tool of dredging thorn 83
There is the tiny flow-conveying groove 831 being arranged along bus, petroleum can flow into screw pump ontology 1 by flow-conveying groove 831 at this time, together
When due to the top of filter plate 7 pressure release, filter plate 7 will rebound rising reset under the action of spring 9, continue work
Make.
Due to the impurity on filter plate 7 can accumulate it is more and more, to be offered clearly in the side wall that material enters neck 11
Washing lotion import 12, and it is located at the top of filter plate 7, the bottom of screw pump ontology 1 is provided with rinse liquid outlet 13.Using one
Impurity after the time of end on filter will be accumulated, to influence material inflow, can close motor 6 at this time, at this time material
It will not be inhaled into screw pump ontology 1, cleaning solution is then poured by filter washing water inlet, cleaning solution, which will press against, has accumulated impurity
Filter decline, the dredging thorn 83 on filter grid 8 passes through filter hole 71 so that filter is dredged, meanwhile, cleaning solution
Meeting dissolved impurity, after washing away a period of time, the impurity for being accumulated in 7 top of filter plate will all be charged screw pump ontology 1
It is interior, and flowed out by rinse liquid outlet 13, the cleaning to filter is not only realized during this, while also having cleaned screw rod
The component inside ontology 1 is pumped, further reduced the problem of coupling rod will not accumulate impurity.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
