Abstract
The utility model relates to a wear resistant fan, which comprises a shell, an impeller assembly, a front cover board, a back cover board and a driving shaft. The shell and the impeller assembly are respectively made of thermometal composite wear resistant steel plates. The thermometal composite wear resistant steel plate is wear resistant plate product, which takes base metal as matrix and is formed from compositing wear resistant layers through a build-up welding method. The base metal is selected from common carbon steel, low alloy steel or stainless steel. The wear resistant layer is an alloy which takes high-hardness metal boro carbon compound as hard strengthening phase. The vanes of the impeller assembly are in an involute shape. The shell and the impeller assembly of the utility model are manufactured through the surface wear resistant build-up welding technology, the surface of a build-up welding layer is smooth and uniform, the service life of the fan is effectively prolonged and is improved by 2 to 3 times. The utility model has the advantages of reasonable conformation and simple manufacture and is particularly suitable for use as the fan of a concrete production line.
Description
Technical field
The utility model relates to a kind of blower fan, specifically a kind of wear resistant fan.
Background technique
We know, present stage China's technology of producing cement near international most advanced level, the dry cement production line of daily output more than 5000 tons puts into production in a large number.Cement produced with the dry method production has two links to be unable to do without blower fan: the one, gather dust, and the 2nd, the pneumatic powder that selects.Investigation shows: the fan life that use on these two links in domestic many cement plants is all undesirable, and under extreme case, draught fan impeller lost dynamic balancing in 7～10 days, and casing 15～20 days is worn out.The blower fan that uses under this occasion, its inefficacy main cause are the erosive wear that cement slurry that gas is carried secretly or grog powder cause.
At present, of home make blower fan selects for use common low carbon steel plate or low-carbon and low-alloy steel plate to make impeller or casing usually.This is that restriction by its work characteristics and classical production process is determined.On the one hand, the working speed of blower is that rotary inertia is very big, requires the manufactured materials of impeller to have enough toughness more than 1400 commentaries on classics; On the other hand, wheel member is to use welding procedure that blade, wheel hub and forward and backward dish assembly welding are formed together, requires material to have good weldability, generally avoids adopting the steel with the tendency of quenching.As everyone knows, the wear-resistant ability of common low carbon steel plate or low-carbon low-alloy steel a little less than, therefore, under the bigger occasion of dust loading, work, working life is extremely undesirable.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of structure reasonable, and manufacturing process is simple, resistance to wears the wear resistant fan of long service life.
The technical scheme in the invention for solving the above technical problem is: a kind of wear resistant fan, it includes casing, the impeller assembly, front shroud, back shroud, live axle, casing is provided with intake grill and exhaust outlet, the bottom is provided with supporting leg, the impeller assembly is by blade, wheel hub and shroud, hub disk is formed, it is characterized in that: casing and impeller assembly are made by the multiple layer of bimetal wear-resisting steel plate respectively, the multiple layer of bimetal wear-resisting steel plate is to be the wearable plate goods that matrix is made by overlaying method complex abrasion-proof layer with the mother metal, said mother metal is selected Ordinary Steel for use, the low-alloy steel or stainless steel, wearing layer be a kind of be the alloy of hard hardening constituent with high hardness metal carbon-boron compound, the blade of impeller assembly is an involute shape.
The utility model casing and impeller assembly are made by the multiple layer of bimetal wear-resisting steel plate respectively, the multiple layer of bimetal wear-resisting steel plate then is to make by the hard facing technology, overlay cladding surface smoothing, evenly is enough to guarantee the stability in dynamic balancing and flow field, and the blade of impeller assembly is an involute shape.Against existing technologies, the utility model improves its working life by the abrasive resistance on intensifying, overflowing surface, improves life-span 2-3 doubly.The utility model structure is rationally made simply, and the blower that is particularly suitable for the making cement production line is used.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the schematic cross-section of Fig. 1.
1. casings among the figure, 2. back shroud, 3. intake grill, 4. front shroud, 5. impeller assembly, 6. live axle.
Embodiment
From Fig. 1, Fig. 2 as can be seen, a kind of wear resistant fan of the utility model, it includes casing 1, impeller assembly 5, front shroud 4, back shroud 2, live axle 6, casing 1 is provided with intake grill 3 and exhaust outlet, the bottom is provided with supporting leg, and impeller assembly 5 is formed by blade, wheel hub and shroud, hub disk assembly welding together.
Characteristics of the present utility model are: casing 1 and impeller assembly 5 are made by the multiple layer of bimetal wear-resisting steel plate respectively, and the multiple layer of bimetal wear-resisting steel plate is to be the wearable plate goods that matrix is made by overlaying method complex abrasion-proof layer with the mother metal.Said mother metal can be selected Ordinary Steel, low-alloy steel or stainless steel as required for use, under the condition, mainly provides mechanical performance index such as intensity, toughness under arms, resists external active force; Surface wear-resistant layer mainly provides the abrasion resistance properties index, and two kinds of materials are born different task separately, the performance optimum performance.Owing to there is mother metal to resist external active force, surface recombination wearing layer alloy can take into full account wear resistance, realizes hypereutectic tissue, utilizes the high micro-penetration hardness of a precipitated phase to improve wear-resisting property.The surface recombination wearing layer be a kind of be the alloy of hard hardening constituent with high hardness metal carbon-boron compound.The blade of impeller assembly 5 is an involute shape, is arranged between shroud, the hub disk.
The utility model casing and impeller assembly are made by the hard facing technology, overlay cladding surface smoothing, even, and the blade of impeller assembly 5 is an involute shape, is enough to guarantee the stability in dynamic balancing and flow field.The utility model is by adopting wear-resistant structure, and the abrasive resistance on intensifying, overflowing surface has prolonged working life of blower fan effectively, improves life-span 2-3 doubly.The utility model structure is rationally made simply, and the blower that is particularly suitable for the making cement production line is used.
