Abstract

The utility model relates to a clinker crusher, the revolving gear of which is formed by that a hub is sheathed on a main shaft through a detachable structure, a hub connection flat pan is connected with the hub, 4 to 5 layers of flat pans are arranged on the main shaft, 4 to 20 equi-spaced fixed crushing parts in a radial direction are distributed on the circumference of each layer of flat pans, a composite lining board is arranged on the inwall of a barrel body opposite the crushing parts, and gaps between the crushing parts and the composite lining board are gradually reduced from top to bottom to form a two-face staircase shape. When ring valves outside the crushing parts are abraded, the problem can be solved by that ring valves which are not abraded are caused to be toward outside by rotating the crushing parts, or the abraded outside ring valves are outwards moved for a distance. Life time can be prolonged, and efficacy can be enhanced.

Description

The clinker pulverizer

The utility model relates to a kind of clinker pulverizer, can be widely used in the pulverizing of building materials, metallurgy industry and ore, belongs to technical field of powder engineering such as clinker and mineral pulverizing.

Similar in the past technology, a kind of vertical shaft crusher is arranged, include the motor that is fixed on the gear frame through one of the V-Belt Drive rotor portion of fixing vertical bar tup radially, this rotor portion is placed in the fixing cylindrical shell, in putting into cylindrical shell, rotated material the impact of tup, the extruding and make material be broken into graininess, but because of rotor portion is fixing plumb head, and the number of plies is few, so generation is broken inhomogeneous, behind the broken powder particulate material is arranged, tup is regulated difficulty, distance is short, has the life-span short, the shortcoming that broken total amount is few.

The purpose of this utility model is at above-mentioned the deficiencies in the prior art, provides a kind of assurance in small, broken bits, and crushing part level clinker pulverizer many, easy to adjust.

For achieving the above object, the utility model adopts following scheme, referring to Fig. 1～3, the utility model clinker pulverizer part same as the prior art is also to comprise the motor (24) that is fixed on the transmission base plate (26), and by the main shaft portion of motor (24) through the transmission mechanism driving, be characterized in its rotating mechanism be wheel hub (15) but be contained on the main shaft (9) with detaching structure, wheel hub connects square position (14) and is connected on the wheel hub (15), 4～5 layers of wheel hub square position (14) are housed on the main shaft, are spacedly distributed on the circumference of every layer of square position (14) the fixing crushing part (16) of 4～20 warp-wises is housed; On crushing part (16) opposite cylindrical shell (11) inwall combined lining board (12) is housed, the crack reduces from top to bottom gradually between the crushing part (16) of each layer hub connection square position (14) and the combined lining board (12), form two sides ladder form, distinguish (16a) or the flexible ring that weares and teares crushing parts (16) for the ring that rotates the wearing and tearing of changing the crushing part of upward adorning square position (14) (16) and distinguish that (16a) is constant to guarantee the gap, 1. (14) periphery equidistantly has radially groove (14a) in the square position, and has 4 row's screw holes can be with fixed head (19) tightening in along square position (14) radially on the groove (14a) in the both sides of groove; 2. perpendicular to the crushing part (16) that little axle (20) is housed on the fixed head (19) and can rotates around little (20); The round nut (17) and the bolt (32) of 3. little axle (20) upper end do not change crushing part (16) tightening that rotation is adjusted to an orientation.

When the utility model clinker pulverizer uses through long-time, owing to crushing part (16) is worn when making the gap not meet technological requirement, can compensate adjustment by following dual mode, 1. bolt (32) and round nut (17) be unclamped fixed head (19) is outwards moved along the footpath, square position together with little axle; 2. unclamp round nut (17), make another unworn ring lobe (16a) replace the position and the tightening of wear ring lobe crushing part (16) rotation.

The utility model has the following advantages compared with the prior art:

1. crushing part can use more than 10 months; 2. the crushing part utilization rate is 75-80%;

3. energy consumption is little, and is littler by 20～25% than general grog pulverizer; 4. the crushing maximum can reach 300t/h

Clinker.

Embodiment: Fig. 1-Fig. 3 is a concrete scheme of the utility model clinker pulverizer:

The utility model comprises belt housing (1); bead apex (2); big belt pulley (3); feed hopper (4); last platen (5); upper bearing (metal) (6); loam cake (7); protective sleeve (8); main shaft (9); spreading disk (10); cylindrical shell (11); combined lining board (1 2); spreading disk hub (13); square position (14); wheel hub (15); crushing part (16); round nut (17); location-plate (18); fixed head (19); little axle (20); bearing block (21); base (22); small belt pulley (23); motor (24); motor frame (25); transmission base plate (26); sealing shroud (27); seal cover (28); bearing (29); (30); hopper (31).Rotary main shaft partly is that spreading disk hub (13) and wheel hub (15) are installed on the main shaft (9), connect spreading disk (10) by spreading disk (13) again, wheel hub connects square position (14), utilize little axle (20), location-plate (18), fixed head (19), square position (14) and crushing part (16) are fixed up, combined lining board (12) is installed on the cylindrical shell corresponding with crushing part (11), just can adjust to the gap of 8-100mm between combined lining board (12) and the crushing part (16), the adjustment in gap is decided according to the size of using factory's raw meal particle size, if use factory's maximum feed granularity to be dmax (mm), 0.8dmax (mm) is adjusted in gap between first row's crushing part (16) and the combined lining board (12), be arranged in order the most following and gap 8-10mm row's crushing part (16) and combined lining board (12), use successively when using crushing part (16) (I), (II), (III), (IV), and then utilization (1), (2), (3), (4) four rounds, outwards regulate successively, make crushing part (16) and combined lining board (12) keep certain clearance.

Material is fed in the body from body upper charging aperture (4), spreading disk (10) by its rotor block top is sprinkled in the gap between combined lining board (12) and the crushing part (16) equably, in its dropping process, by each layer crushing part (16) repeated stock, extruding, and it is broken gradually, the effect that is subjected to various pressure in shattering process makes between the particle simultaneously and rubs, grind, bossing is lost, and the surface is subjected to cooling off the effect of processing, makes particle lose toughness, peel off gradually on the surface, the surface produces stress each other repeatedly after friction is peeled off, make particle tired gradually and cause fragmentation.
