Abstract
A high-strength antiwear material hopper features that the detachable antiwear liner plates or the integrally cast antiwear layer is attached to its inner surface. Said antiwear liner plates and its fixing screws are made of antiwear low-Mn steel or quenched high-hardness steel. Its advantage is long service life.
Description
Technical field the present invention relates to the silo of a kind of pulverizing (or grinding) equipment, specifically a kind of high strength anti-abrasion silo that is applicable to coal-fired firepower (heat) power plant, coal washing plant and relevant industrial and mineral turnover material.
Background technology for a long time, coal-fired station, thermo-power station and other have the industrial and mining enterprises that material is pulverized (or grinding) equipment, as the raw coal of ball mill material enter, coal dust output hopper adopts B3F steel plate riveting system to be welded usually.This silo dashing of abrasive body steel ball pound and the erosive wear of material under, promptly breakdown in a short time, mill is logical, causes dust from flying, serious environment pollution; Lost efficacy because of silo damages simultaneously, and caused the frequent shutdown soldering to repair, waste of manpower in large quantities, material resources and fund also are unfavorable for safety.
Summary of the invention the object of the present invention is to provide that a kind of mechanical strength height, wear resistance are strong, the high strength anti-abrasion silo of long service life, pounds to solve because of abrasive body steel ball etc. dashes, the material wearing and tearing make the too fast puncture of hopper, logical this technical problem that lost efficacy of mill.
The object of the present invention is achieved like this: this high strength anti-abrasion silo is to be provided with detachable abrasion-proof backing block or integral cast wearing layer in the silo housing on the material easy-wearing surface, abrasion-proof backing block is provided with ellipse, the square or special screw of polygon, with bolt liner plate is fixed on the silo housing, abrasion-proof backing block, bolt are to be made by the steel that antiwear low-manganese steel or process Quenching Treatment Rockwell hardness through Quenching Treatment reach HRC48-68.
At the semicircle material channel in the silo housing, above-mentioned abrasion-proof backing block is spliced by both sides transition liner plate and middle at least one block of arc liner plate, and middle arc liner plate surface is provided with guiding gutter, screw is located at the junction of adjacent guiding gutter.
High strength anti-abrasion silo provided by the invention can improve the mechanical strength of silo greatly, pounds thereby resist interior the dashing of steel ball of milling apparatus effectively; Improved the wear resistance of silo, the wearing and tearing that material is washed away are reduced to minimum degree, have prolonged the service life and the service cycle of equipment effectively, have reduced the number of times of shutting down maintenance, soldering repairing.Compare with the product that uses the B3F steel to make, can increase the service life 6～8 times, farthest guaranteed the reliability and security of pulverizing (or grinding) equipment operation.
Description of drawings Fig. 1 is a roundel hopper construction schematic diagram
Fig. 2 is square silo structural representation
Fig. 3 is the A-A profile of Fig. 1, Fig. 2

Among the figure: 1-silo housing; 2-abrasion-proof backing block or wearing layer, 201-side plate, the arc liner plate of 202-; The 3-manhole door; The 4-screw.
The specific embodiment as shown in Figure 1 to Figure 3, this high strength anti-abrasion silo is a lining cutting abrasion-proof backing block 2 on the semicircle material channel in silo housing 1, abrasion-proof backing block 2 is provided with ellipse, the square or special screw 4 of polygon, be convenient to bolt abrasion-proof backing block 2 is fastened on the silo housing 1, abrasion-proof backing block 2 and bolt are made by the steel that antiwear low-manganese steel or process Quenching Treatment Rockwell hardness through Quenching Treatment reach HRC48-68.During manufacturing, Quenching Treatment, lonneal must be that integral body is carried out, and guarantee that quenching hardness is even.
As shown in Figure 3, Figure 4, at the semicircle material channel in the above-mentioned silo housing 1, abrasion-proof backing block 2 is spliced by two side plates 201 and middle at least one block of arc liner plate 202, arc liner plate 202 surfaces are provided with guiding gutter, screw 4 is located at the Jiao Fengchu of adjacent guiding gutter, and connecting bolt is not easy to wear.Abrasion-proof backing block 2 spliced global shapes are not limited to side plate 201 and arc liner plate 202 by the decision of silo import and export mix form.
Above-mentioned abrasion-proof backing block 2 adopts detachable block connecting method, is to be convenient to the staff to put into installation, maintenance and the part changes from the manhole door 3 of pulverizing (or grinding) equipment.
Above-mentionedly on the semicircle material channel in silo housing 1, establish the abrasion-proof backing block 2, also can adopt the mode of integral cast wearing layer, wearing layer still adopts the antiwear low-manganese steel of process Quenching Treatment or reaches the steel of HRC48-68 through the Quenching Treatment Rockwell hardness.
