Description
Technical field
The invention belongs to auger loader technical field, particularly can carry a kind of titanium auger loader of severe corrosive material.
Background technology
Auger loader is widely used in every profession and trade, as industries such as building materials, chemical industry, electric power, metallurgy, coal, grains, be applicable to level or conveying powdered, the granular and little lump material that tilts, as ash, slag, cement, coal, grain etc., temperature of charge is less than 200 DEG C.Auger loader principle of work is, when screw shaft rotates, by the gravity of material and the friction force that produces with auger loader inner walls thereof, the inner walls of material along conveyer under the propelling movement of blade is moved forward, its situation is done motion of translation as not revolvable nut along the screw rod rotated, material in the migration of middle bearing, is then the thrust relying on go-ahead material below.So the transport of material in conveyer is a kind of slipping motion completely.Material is passed and carries by the helicallobe rotated, and the power that material is not rotated together with auger blade is that material own wt and auger loader inner walls are to the friction drag of material.Auger loader of the prior art manufactures primarily of carbon steel or stainless steel, because the corrosion resisting property of material own is poor, be unsuitable for the material carrying severe corrosive, and titanium material has good corrosion resisting property, be suitable for the material carrying severe corrosive, but the intensity of titanium material own is lower, the working condition requirement of convey materials can be met, but the requirement of strength of auger loader spindle nose can not be met, so, in order to ensure the intensity of the spindle nose of auger loader, the antiseptic property of auger loader spindle nose can be ensured again simultaneously, need to invent a kind of spindle head connecting structure that can meet titanium that intensity can meet again antiseptic property and be connected with steel.But because titanium and steel at high temperature can react generation frangible compounds, so titanium and steel can not realize strength solder joints.Titanium and steel have two kinds of welding methodes can they weld togethers at present, one is explosive welding, as titanium steel clack steel plate, but, explosive welding Problems existing can only be that face is welded with face, there is certain area requirements, in addition shearing strength value is very low, the applying working condition requirement of the spindle nose of auger loader can not be met, two is adopt one or more transition metal segmentations welding, can titanium and steel weld together, but Problems existing is, although there is no area requirements, but weld strength is extremely low, more can not meet the applying working condition requirement of the spindle nose of auger loader.The method of attachment that the application for a patent for invention that application number is CN201310037483.8 discloses a kind of titanium volume and stainless steel band and the transition band adopted thereof, described transition band comprises titanium plate, stainless steel sheet and attaching parts, wherein, one end of described titanium plate is set up on described stainless steel sheet, and the titanium plate of lamination portion is provided with one or more mounting groove; One end of described attaching parts is directly welded on stainless steel, and the other end through described mounting groove welding on stainless steel, makes titanium plate and stainless steel sheet link together, titanium steel can be avoided directly to weld.But this structure only ensures that adopted transition band has quality and enough intensity well, be only applicable to the connection of titanium plate and stainless steel sheet, the applying working condition requirement of the spindle nose of auger loader can not be met.
Summary of the invention

The technical solution used in the present invention comprises the housing unit be made up of housing and screw shaft support, be provided with on the right side of housing by motor reducer, coupler, the nose assembly of head bearing assembly and housing head end poted assemblies composition, the tail assembly be made up of tail bearing assembly and housing machine tail end poted assemblies is installed on the left of housing, be provided with in housing by spindle nose, central siphon, the screw shaft of central siphon attaching parts and helicallobe composition, described spindle nose to insert in the central siphon of end, screw shaft two ends and is welded as a whole, be welded as a whole by central siphon attaching parts between central siphon in the middle of described screw shaft, described central siphon and helicallobe are welded as a whole, described spindle nose comprises spindle nose axle, the first sleeve pipe and the second sleeve pipe is filled at spindle nose outer shaft sleeve, described first sleeve pipe and the second sleeve pipe are welded as a whole, spindle nose axle and the second sleeve pipe are processed with the plug mounting hole that some positions are corresponding, plug is inserted in plug mounting hole, plug lays liner, and at upper surface build-up welding titanium overlay cladding, make spindle nose axle, first sleeve pipe, second sleeve pipe, plug, liner becomes to be integrated with titanium overlay cladding.
Described housing, screw shaft support, central siphon, central siphon attaching parts, helicallobe, the first sleeve pipe, the second sleeve pipe, liner and titanium overlay cladding adopt titanium material to make.
Described spindle nose axle and plug adopt steel to make.
Described spindle nose axle is stepped shaft.
Plug mounting hole corresponding to the described some positions processed on spindle nose axle and the second sleeve pipe is axial layered arrangement, circumferential annular distribution.
Compared with prior art, the invention has the beneficial effects as follows:
Housing of the present invention, screw shaft support, central siphon, central siphon attaching parts, helicallobe, first sleeve pipe, second sleeve pipe, liner and titanium overlay cladding all adopt titanium material to make, spindle nose axle and plug adopt steel to make, the spindle nose of screw shaft especially of the present invention adopts the first sleeve pipe and the second sleeve pipe that make at the spindle nose outer shaft sleeve dress titanium material of steel, first sleeve pipe and the second sleeve pipe are welded as a whole, spindle nose axle and the second sleeve pipe are processed with the plug mounting hole that some positions are corresponding, the plug of steel is inserted in plug mounting hole, the plug of steel is laid the liner that titanium material makes, and at upper surface build-up welding titanium overlay cladding, the first sleeve pipe that the spindle nose axle that steel are made and plug and titanium material make, second sleeve pipe, liner becomes to be integrated with titanium overlay cladding, both ensure that the intensity of screw shaft, in turn ensure that the corrosion stability of screw shaft, auger loader can be met requirement that operating mode intensity can meet again antiseptic property, and structure is simple, safe in operation is stablized, long service life, being applicable to operation pressure gauge pressure is normal pressure, the conveying of the strong corrosive media of operating temperature≤200 DEG C.
