Abstract

The utility model discloses a novel submersible water impeller which is applied to water pools, oxidation ditches and the like in water supply and drainage engineering. The novel submersible water impeller comprises a host (1), a sliding sleeve (2), a bracket (4) and a guide rod (5), wherein the bracket is provided with a base (3), the bracket and the base are of an integrated structure, and the host is fixed on the base in a threaded connection manner; and the sliding sleeve is sleeved on the guide rod in a sliding manner, the middle part of the sliding sleeve is provided with a bearing (23), and a middle shaft (9) arranged in the bearing is connected with the base. According to the novel submersible water impeller disclosed by the utility model, the host and the bracket can be subjected to comprehensive detection and maintenance in a manner that the host and the bracket are raised out of a water surface as a whole, so that the occurrence of serious mechanical accidents that the bracket falls apart, the guide rod is rubbed off, the host falls to the bottom of a pool, and the like is avoided; and the weight of the host, base and bracket all acts on the ground, so that the stress levels of the sliding sleeve and the guide rod are reduced, the friction and wear are reduced, the guide rod is effectively prevented from being rubbed off, and the service lives of the guide rod and the sliding sleeve are prolonged.

Description

The Novel submerged impeller

Technical field

The utility model relates to water processor machinery, relates in particular to the submersible water impeller that pond, oxidation ditch etc. in the water supply and sewage work use, the homogeneous that can be widely used in all kinds of ponds in the water supply and sewage work, water treatment system stir and the engineering such as plug-flow in.

Background technology

In present engineering of water treatment was used, oxidation ditch particularly was used for that homogeneous stirs and the equipment of plug-flow mainly is submersible water impeller.The main integral part of submersible water impeller has: main frame, support, sliding sleeve, guide rod etc.

Referring to Fig. 1, it is present widely used large and medium-sized submersible water impeller.On base 3, sliding sleeve 2 is welded on the tail end of base 3 to its main frame 4 by bolted, and main frame, sliding sleeve and base form integral structure.Main frame 4 cross-under wireline 8 are connected with lifting mechanism 6 by the upending frame 7 that is fixedly arranged on the oxidation ditch aisle.Handle lifting mechanism 6, can realize main frame 4, base 3, the lifting of sliding sleeve 2 on carriage 1 of submersible water impeller.Main frame and carriage 1 adopt separate type, host machine part directly is slipped on the carriage by the guide effect of sliding sleeve 2 and guide rod 5 during installation, realize automatic coupling with carriage, so main frame can be separated from cradle, be lifted out that the water surface detects, routine maintenance, repairing at different levels.But carriage 1 is to be bolted the bottom that is fastened on guide rod 5, carries out maintenance and repair so can't be lifted out the water surface.The defective of this structure is: the shock and vibration that main frame 4 produces in operational process, the power of rocking pass to sliding sleeve 2 and carriage 1 by base 3, make to reach between carriage 1 and the base 3 between sliding sleeve 2 and the guide rod 5 to produce metal frictional abrasion.When unit operation after the several years, carriage, base can occur badly damaged even fall apart, and guide rod rubs phenomenon, causes main frame 4 to drop at the bottom of the pond.

Referring to Fig. 2, it is present comparatively common medium and small submersible water impeller.Its main frame 3 is not established base, directly adopts bolt to be fixed with sliding sleeve 2 and is connected, and adopt separate type with its carriage 1.Main frame 3 cross-under wireline 8 are connected with lifting mechanism 6 by the upending frame 7 that is fixedly arranged on the oxidation ditch aisle.Handle lifting mechanism 6, main frame 4 can directly be slipped on the carriage 1 with the guide effect of sliding sleeve 2 by guide rod 5, realizes automatic coupling with carriage 1.When main frame 3 needs to safeguard, during maintenance, main frame 3 separates out from carriage 1 together with sliding sleeve 2 and is lifted out the water surface.Because carriage 1 is to be bolted on the bottom and the pre-embedded steel slab at the bottom of the pond of guide rod 5, carry out maintenance and repair so can't be lifted out the water surface.The defective of this structure is: the shock and vibration that main frame 3 produces in operational process, the power of rocking pass to sliding sleeve and carriage, make to reach between carriage and the main frame between sliding sleeve and the guide rod to produce metal frictional abrasion.When unit operation after the several years, carriage can occur badly damaged even fall apart, and guide rod rubs phenomenon, causes main frame 3 to drop at the bottom of the pond.

Summary of the invention

The utility model purpose is to provide a kind of sound construction, long service life, and failure rate is low, economical and practical, simultaneously convenient detection and the Novel submerged impeller that keeps in repair.

The utility model Novel submerged impeller, its structure comprises: main frame, sliding sleeve, carriage, guide rod, it is characterized in that described carriage is provided with base, carriage and base are integrated, and the mode that main frame then is threaded connection is fixed on the base; Sliding sleeve is slidingly socketed on guide rod, and base is connected with sliding sleeve.

Because producing, rocks the main frame operation process, described sliding sleeve middle part setting-in axle sleeve, and this axle sleeve cross-under axis is connected with base, and the sliding sleeve on making carriage and being installed in guide rod forms relative rotation, and buffering discharges the reactive force that produces in the main frame operational process guide rod.

Described sliding sleeve, its structure comprises two side plates, left side plate up and down and front and back position install altogether four pairs of totally 8 pulleys; The inboard installing of side plate slide plate, the further friction of minimizing and buffering sliding-casing and guide rod.

Submersible water impeller of the present utility model, base and bracket is integrated, and main frame is fixed on the base, and the weight of main frame all acts on ground, pond, avoids main frame to directly act on the sliding sleeve, to reduce the stressed degree of sliding sleeve assembly and guide rod; Main frame and carriage can be left the water simultaneously and be carried out complete detection, maintenance, avoid carriage to fall apart, the generation of the great mechanical accident such as guide pillar rubs, main frame drops at the bottom of the pond; Sliding sleeve is connected with carriage by Middle shaft assembly, cause the wall pressure of guide rod in the time that floor support can being digested because of the ground injustice, buffering discharges that main frame produces in operation waves, vibration, surging force, reduces the mutual frictional wear between sliding sleeve assembly and guide rod; Sliding sleeve installing pulley and slide plate reduce the metal friction between sliding sleeve and guide rod, play the effect in the work-ing life that prolongs sliding sleeve assembly and guide rod.
