Abstract

The utility model relates to a high strength screw conveyor, comprises a pole body, be provided with a plurality of thread on the body of rod, the body of rod and thread adoption nylon or polyethylene or polyformaldehyde or polytetrafluoroethylene material make. The utility model discloses a stainless steel is avoided adopting by the screw rod, makes the weight of screw rod lighter, and the thread can form on the screw rod in direct turning, avoids to carried out welded connection in the past, material cost saves 60%, and alkaline -resisting, sour when the screw rod stirs in the medical kit, crooked indeformable, 5 -6 is also improved doubly to the life -span, has solved stainless steel screw conveyor rupture problem.

Description

High strength conveying screw rod
Technical field
The utility model relates to a kind of high strength conveying screw rod.
Background technology
Strainer squeezer or sleeping spiral shell discharging sedimentation centrifuge is adopted in sewage sludge process.All need to adopt flocculant and clear water to prepare in medicine-chest, the proportioning of general medicine and clear water is parts per thousand, and after this just requires clear water and the continuous stirred for several of medicine hour, flocculant just can be dissolved in the water.
Chemicals dosing plant conveying screw rod, have certain Acidity of Aikalinity with flocculator during alloy steel, alloy steel easily corrodes, and need often change, and generally will not adopt, and existing chemicals dosing plant conveying screw rod mostly is corrosion-resistant steel.
Conveying screw rod in the past as shown in fig. 1, belongs to slender axles, processing time consuming and difficulty is larger.Split type splicing can only be adopted man-hour adding; conveying screw rod in the past comprises thread 10, adapter shaft 30 and thread bar 20; during split splicing; first each thread 10 is made annulus; then each thread 10 is welded on thread bar 20; finally welded with adapter shaft 30 by thread bar 20, weld is A place in figure, and in use weld often can rupture again.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provides a kind of high strength conveying screw rod, solves the problem of screw rod easy fracture in the past.
The utility model solves the technical scheme that its technical matters adopts: a kind of high strength conveying screw rod, comprise the body of rod, the described body of rod is provided with several threads, the described body of rod and thread adopt nylon or polyethylene or polyformaldehyde or polytetrafluoroethylene material to make.
Further, described lever front end forms thread construction section, and each thread is arranged on thread construction section, and the diameter of described thread construction section is φ 18mm.
Further, described thread and the body of rod are structure as a whole.
Further, described thread is rectangle thread, and the pitch of described thread is 28mm, and the width of described thread is 4mm.
Further, the rear end of the described body of rod forms the keyway for placing flat key.
Further, the described body of rod is length 350 ~ 450mm.
The beneficial effects of the utility model are: screw rod of the present utility model is avoided adopting stainless steel, and the weight making screw rod is lighter, and thread can direct turning formation on screw rod, avoid to being welded to connect in the past; Material cost saves 60%, when screw rod stirs in medicine-chest, alkaline-resisting, sour, bending indeformable, and the life-span also improves 5-6 doubly, solves corrosion-resistant steel conveying screw rod and to fracture problem.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is the schematic diagram of traditional conveying screw rod;
Wherein, 10, thread, 20, thread bar, 30, adapter shaft;
Fig. 2 is the schematic diagram of the utility model screw rod;
Wherein, 1, the body of rod, 2, thread.
Detailed description of the invention
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 2, a kind of high strength conveying screw rod, comprises the body of rod 1, the body of rod 1 is provided with several threads 2, and the body of rod 1 and thread 2 adopt nylon or polyethylene or polyformaldehyde or polytetrafluoroethylene material to make.
It is 1.15 that nylon has lightweight, density, is stainless 15%, and material cost saves more than 60%.The processing characteristics of nylon is better than corrosion-resistant steel.Tooling cost is only stainless 1/2.Improve effect.Nylon friction coefficient is lower than corrosion-resistant steel by 8.8, alkaline-resisting, sour, bending indeformable, and the life-span also improves 5-6 doubly, solves corrosion-resistant steel conveying screw rod and to fracture problem.
Polyethylene (PP), mechanical strength is good, resist bending, fatigue property are excellent, 100 DEG C of indeformable density of Long-Time Service are light.Polyformaldehyde (POM), very high hardness, rigidity, resistance to abrasion are all good; Teflon rod is acidproof, alkaline-resisting, lubricating type is fabulous.
The body of rod 1 front end forms thread construction section, and each thread 2 is arranged on thread construction section, and the diameter of thread construction section is φ 18mm.The rear end of the body of rod 1 forms the keyway for placing flat key.The body of rod 1 leading portion diameter is φ 25mm, stage casing φ 35mm.
Thread 2 and the body of rod 1 are structure as a whole.Thread 2 direct turning on the body of rod 1 is formed.
Thread 2 is rectangle thread, and the pitch of thread 2 is 28mm, and the width of thread 2 is 4mm.
Spiro rod length of the present utility model is at 350 ~ 450mm, because the material that have employed lighter weight is made, that therefore can do is so elongated, the mode that the segmentation that stainless steel need not be adopted to use is welded to connect, nowadays, screw rod quality is light, not frangibility, withstanding corrosion, avoids welding stress, effective raising resistance to fracture, uses anniversary no exceptions in the supporting LW650 of being applied in horizontal screw centrifuge medicine-chest.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification sheets, must determine its technical scope according to right.
