Abstract
The utility model relates to a ball mill double-faced arc ladder wave-shape combined self-fixed lining plate, which is characterized in that the lining plate is formed by combining asymmetric double-faced arc ladders; the angle of normal lines of the lining plate ranges from 8 degrees to 15 degrees; the ball mixing linear surface of the lining plate ranges from 100mm to 200mm; a ball throwing curved surface ranges from 60mm to 150mm; and the width of a wave crest of the lining plate ranges from 80mm to 120mm. The lining plate adopts a double-faced arc ladder combined self-fixed type, has reasonable combination of corrugations of a cylinder and the lining plate, changes the fastening mode that bolts are arranged inside the cylinder and enables the bolts to have small stress effect. By adopting an active abrasion-resistant surface, namely the ball mixing linear surface, the lining plate is capable of effectively decreasing steel ball loading capacity by 10% to 20%, reducing running power of equipment by 8% to 15% and improving flour milling effect by 5% to 15%. Moreover, the lining plate is convenient in adjustment, safe and reliable, high in flour milling output rate, low in energy consumption and adaptable to a ball mill with an inner diameter ranging from 2900mm to 4700mm.
Description
Technical field
The utility model relates to a kind of liner plate, is specifically related to be used for the liner plate of thermal power plant ball mill.
Background technology
The ball grinding machine lining board waveform of thermal power plant is divided into balancing waveform liner plate, waveform ripple liner plate, T shape ripple liner plate, minor undulations ripple liner plate, tooth ripple liner plate, trapezoidal ripple liner plate etc. substantially.Its effect is to cooperate steel ball that coal grinding is become to meet the powdered granule of system requirements, and above-mentioned waveform liner plate exists dribbling, toss ability, and the grinding efficiency in the coal pulverizer cylindrical shell is low, shortcomings such as powder process undercapacity.Particularly above-mentioned waveform liner plate is in the middle and later periods use, and the powder process ability drop is fast, and the waveform hold facility is poor, needs to increase machine utilization, strengthens steel ball loading capacity and could satisfy the powder process ability.Be in operation because the defective of structural design causes maintenance workload big, difficult in maintenance, serious cause the improper stoppage in transit of generating set.Existing liner plate adopts a large amount of bolts to fix in design, and bolt is in operation and is in the center of effort of alternate stress, and the break accident that falls of bolt is frequent, liner plate is in operation is prone to faults such as liner plate collapses, structural failure, leakage powder, damage ball mill barrel.Potential operation and security risk have been caused.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned existing shortcoming, operation mechanism according to ball mill, adopt the main and auxiliary face asymmetric waveform combination of resistance to wearing, provide strong, bolt strained little, the two-sided arc ladder of the rational ball mill of the Waveform Design waveform combination of a kind of simple in structure, waveform hold facility from type liner plate admittedly
The two-sided arc ladder of ball mill of the present utility model waveform combination is characterized in that from consolidating the type liner plate: described liner plate is the combination of asymmetric two-sided arc ladder; Liner plate normal angle is 8-15 °, and it is 100-200mm that liner plate is mixed the ball planarea, and the toss curvilinear plane is 60-150mm, and liner plate crest width is 80-120mm.
In order to realize this purpose better, liner plate crest operation debugging is of a size of 80-120mm, and the quantity of liner plate circumferencial direction Wave crest and wave trough pair is 28-42, and liner plate trough radius is 1450-2350mm, has strengthened the waveform hold facility of liner plate.
The utility model liner plate adopts the combined self-fixed formula type of two-sided arc ladder, and the ripple combination of cylindrical shell and liner plate has rationally changed the fastening means of bolt in cylindrical shell.The bolt stressing influence that is in operation is little.Adopt the face that initiatively resistance to wears promptly to mix the ball planarea, can effectively reduce steel ball and carry ball amount 10%～20%, reduce the operate power 8%～15% of equipment, improve powder process and render a service 5%～15%, easy to adjust, safe and reliable, powder process goes out the power rate height, and energy consumption is low.Be applicable to that cylinder internal diameter is the ball mill of 2900-4700mm.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that of Fig. 1 implements to install illustration.
Among the figure 1, liner plate, 2, ball mill barrel, 3, bolt, 4, the riveting plate, R, cylindrical shell radius, R1, liner plate trough radius, are mixed the ball planarea, S2, toss curvilinear plane, A, liner plate crest debugging size, B, liner plate crest width, a, liner plate normal direction angle at S1.
The specific embodiment
The two-sided arc ladder of ball mill of the present utility model combined self-fixed type liner plate, liner plate 1 are asymmetric two-sided arc ladder waveform.
Getting cylindrical shell 2 radius Rs is 1800mm, liner plate trough radius R 1 is 1750mm, mixing ball planarea S1 is 120mm, toss curvilinear plane S2 is 80mm, liner plate crest width B is that 70mm, liner plate normal angle [alpha] are 10.9 °, liner plate crest debugging size A is 90mm, and the quantity of liner plate direction Wave crest and wave trough pair (liner plate crest debugging size * liner plate crest width) is 32.During installation, liner plate 1 closely is connected with the cambered surface of cylindrical shell 2, and liner plate 1 is with whole 32 connections of number of turns amount, and every adjacent liner plates face is installed the location by real, bolt 3 mutually, and liner plate 1 adopts pad to adjust swelling with riveting plate 4, reaches combined self-fixed purpose.Reduce the bolt number, improved security of operation.
