Abstract
The utility model relates to a filter screen structure for vertical dredge pump of major axis includes, sets up the filter screen cylinder body in the dredge pump, the filter screen cylinder body has along first end and second end that its axis direction is relative, first end system with the stiff end that dredge pump looks fixed knot closed, the diameter of the filter screen cylinder body certainly first end extremely the second end is crescent, there are first hole and second hole on the filter screen cylinder body, wherein, the aperture in first hole is less than the aperture in second hole. The utility model has the advantages of: keeping original and intaking under the prerequisite of performance, improving at most water conservancy environment filter capacity down, protecting hydraulic component to avoid the impact of a large amount of tiny particulate matters, suspended solid to extension water pump life.
Description
Technical field
This utility model relates to a kind of filter structure for long-axis vertical dredge pump.
Background technology
In long-axis vertical dredge pump, the filtration through hole on filter screen uses uniform diameters processing, as it is shown in figure 1, such design causes filter screen performance in different water quality environments different so that its versatility is poor.Although the filter pore size of existing design can filter out most particulate matter and float, impeller channel is not blocked, but still can enter runner less than the particulate matter of filter pore size, float, impeller and runner inner surface are impacted, frictionally damage, get off for a long time, water conservancy parts certainly will be damaged and reduce hydraulic performance；Being reduced by filter pore size merely, although filter capacity enhances, its water inlet ability can be affected again, also can lose hydraulic performance.And if carrying out different filter pore size design for different quality environment and can be greatly increased design and manufacturing cost.And all processing upper through hole in existing design in screen surface, do not use surface area optimum, filter screen is cellular, for ensureing its intensity, need to additionally increase gusset.
Utility model content
The purpose of this utility model is to solve the problem that prior art exists the most same diameter in aperture, it is provided that a kind of filter structure for long-axis vertical dredge pump.
To achieve these goals, the technical solution of the utility model is achieved in that a kind of filter structure for long-axis vertical dredge pump, include, the filter screen cylinder being arranged in dredge pump, described filter screen cylinder has along relative the first end of its axis direction and the second end, described first end system and described dredge pump fix the fixing end of combination, the diameter of described filter screen cylinder is gradually increased from described first end to described second end, the first hole and the second hole is had on described filter screen cylinder, wherein, the aperture in described first hole is less than the aperture in described second hole.
It is distributed along the axis direction compartment of terrain of described filter screen cylinder as the preferred version of a kind of filter structure for long-axis vertical dredge pump, described first hole and described second hole system.
Preferred version as a kind of filter structure for long-axis vertical dredge pump, described filter screen cylinder has machining area and non-machining area, described machining area and described non-machining area system are distributed along the circumferencial direction compartment of terrain of described filter screen cylinder, wherein, described first hole and described second hole are in described machining area.
As the preferred version of a kind of filter structure for long-axis vertical dredge pump, the described end of described filter screen cylinder is formed with adpting flange portion.
Compared with prior art; this utility model at least has the advantage that (1) uses the design that a number of big aperture coordinates; on the premise of keeping original water inlet performance; improve the filter capacity under major part water conservancy environment; protection hydraulic part is from a large amount of fine particle things, the impact of float, thus extends water pump service life.(2) filter screen is as first parts of water feeding of water pump, himself structural strength and hydraulic performance also can produce impact to water pump overall performance, it is improved to more conform to fluid dynamic gradual shrinkage filter cylinder, filter cylinder surface area is made rational planning for utilization simultaneously, use non-full Surface Machining to filter the design of through hole to improve intensity and the hydraulic performance of filter screen.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art.
Fig. 2 is the structural representation of this utility model one embodiment.
Detailed description of the invention
With embodiment, this utility model is elaborated below in conjunction with the accompanying drawings.
Referring to Fig. 2, shown in figure is a kind of filter structure for long-axis vertical dredge pump, includes, the filter screen cylinder 1 being arranged in dredge pump, and described filter screen cylinder 1 has along relative the first end 11 and the second end 12 of its axis direction.Described first end 11 is to fix the fixing end of combination with described dredge pump, the diameter of described filter screen cylinder 1 is gradually increased to described second end 12 from described first end 11, having the first hole 13 and the second hole 14 on described filter screen cylinder 1, wherein, the aperture in described first hole is less than the aperture in described second hole.Described first hole and described second hole are the axis direction compartment of terrain distribution along described filter screen cylinder 1.Described filter screen cylinder 1 has machining area 101 and non-machining area 102, described machining area and described non-machining area system are distributed along the circumferencial direction compartment of terrain of described filter screen cylinder 1, wherein, described first hole 13 and described second hole 14 are in described machining area 101.It is formed with adpting flange portion at described first end 11 of described filter screen cylinder 1.
This patent, on the basis of original filter screen, retains a number of filter opening as the macropore in the design, is evenly arranged smaller, more keyhole formation " big aperture design " simultaneously around each macropore.Aperture plays filtration fine particle thing, the effect of float, the reservation of macropore then compensate for aperture deficiency in terms of water inlet ability, and the most original design of its quantity is greatly reduced, thus filter screen is overall while water inlet ability is constant, also improves the filter capacity of entirety.This design makes filter screen can keep premium properties in major part water conservancy environment, and versatility is more preferable.Using tapered cartridge structure, and 4 regions radially retaining one fixed width at bisectors do not carry out filter opening processing in its surface, at such 4, undressed band can play the bracing reinforcement effect of similar gusset without welding gusset again.Structural strength own is guaranteed.Meanwhile, because its undressed filtration through hole, this at 4 undressed band inner surface can be considered as the inwall of certain area of passage, coordinate the tapered cartridge structure more conforming to fluid motion so that filter screen plays the effect of part water-inlet horn, and hydraulic performance is more excellent.
Below only have expressed embodiment of the present utility model, it describes more concrete and detailed, but therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that, for the person of ordinary skill of the art, without departing from the concept of the premise utility, it is also possible to make some deformation and improvement, these broadly fall into protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
