The double-slide shoe mineral slag mill disclosed by the utility model can be used for increasing the contact heat resistance between the cylinder body and the rolling rings, further reducing the temperature of the rolling rings and further reducing the temperature of a supporting bush of a slide shoe bearing. In addition, the double-slide shoe mineral slag mill disclosed by the utility model adopts a connection way through a plurality of groups of the bolts, thereby reducing the problem of fracture of the bolts caused by long-term pulsating alternating current tensile stress and further ensuring the normal operation of equipment.
Description
Technical field
The utility model relates to a kind of pair of crawler shoe slag mill, relates in particular to a kind of two crawler shoe slag mills that can realize that thermal resistance is disconnected.
Background technology
At present, two scaled slide shoe tube mills since simple in structure, power transmission convenient, be easy to characteristics such as manufacturing, be widely used in grinding as slag in the ball milling of cement, slag etc.When two scaled slide shoe tube mills were used for the slag mill, because the difficult mill of slag, in the grinding machine course of work, the mutual bump of steel ball, liner plate and material can produce great amount of heat, makes the discharge end temperature of charge can reach more than 150 ℃.Traditional two scaled slide shoe tube mills are with feed end rolling ring, discharge end rolling ring and cylindrical shell welding; The a large amount of heats that produce during slag milling can cause discharge end rolling ring temperature to raise and heat is conducted on the slide shoe bearing lining tile; Cause its temperature up to more than 75 ℃, because the slide shoe bearing lining tile is a babbit, and the operating temperature of babbit is lower; Thereby cause the slide shoe bearing lining tile to burn out, cause great equipment breakdown.
For addressing the above problem, the method that adopts at present have in cylindrical shell, add thermal insulation layer, to two scaled slide shoe tube mill trickles, force cooling etc. with axial flow blower, though temperature is descended, but still can not reach the requirement of two long-term continuous operations of scaled slide shoe tube mill.
The utility model content
To the deficiency that prior art exists, the utility model provides a kind of and can realize that thermal resistance is disconnected and can guarantee two crawler shoe slags mills that the long-term continuous operation of slag wear smooth shoe bearing lining tile does not damage.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of two crawler shoe slag mills that can realize that thermal resistance is disconnected; Comprise cylindrical shell 1, feed end rolling ring 3, discharge end rolling ring 4, bistrique liner plate 6, feed end casing 8, discharge end casing 9, combined type discharging screening plant 11; Wherein: between cylindrical shell 1 and the feed end rolling ring 3, all adopt bolt to be connected between bistrique liner plate 6 and the feed end casing 8; And also adopt bolt to connect in order between cylindrical shell 1, bistrique liner plate 6, feed end rolling ring 3 threes, said bolt all evenly distributes along the circumferencial direction of cylindrical shell 1; Between cylindrical shell 1 and the discharge end rolling ring 4, all adopt bolt to be connected between discharge end casing 9 and the combined type discharging screening plant 11; And adopt bolt to connect in order between cylindrical shell 1, combined type discharging screening plant 11, discharge end rolling ring 4 threes, said bolt all evenly distributes along the circumferencial direction of cylindrical shell 1.
Above-mentioned cylindrical shell 1 is coated with thermal insulating coating 13 with contact site, the cylindrical shell 1 of feed end rolling ring 3 with the contact site of discharge end rolling ring 4.
Compared with prior art, the utlity model has following advantage and beneficial effect:
Compare existing slag mill with feed end rolling ring, discharge end rolling ring and cylindrical shell welding, the utility model adopts bolt to connect feed end rolling ring, discharge end rolling ring and cylindrical shell, has increased the thermal contact resistance between cylindrical shell and the rolling ring; Simultaneously; Between cylindrical shell and rolling ring, apply thermal insulating coating again, further strengthen the disconnected effect of thermal resistance, when the slag grinder is done; Thereby can reduce the temperature of rolling ring, and then reduce the temperature of slide shoe bearing holder watt.In addition, the utility model adopts the bolted modes of many groups, reduced because of the bolt bolt fracture problem that the alternation tension causes of being pulsed for a long time, thus the normal operation of the equipment of assurance.
When the two crawler shoe slag grinders of the utility model were done, the temperature of feed end bearing retainer watt remained on below 40 ℃, the temperature of discharge end bearing retainer watt remains on below 50 ℃, thereby had avoided pulling and burning the damage phenomenon of slide shoe bearing holder watt.
Description of drawings
Fig. 1 is the structural representation of the two crawler shoe slag mills of the utility model, wherein, and 1-cylindrical shell, 2-slipper shoes body; The rolling ring of 3-feed end, the rolling ring of 4-discharge end, 5-bolt, 6-bistrique liner plate; The 7-bolt, 8-feed end casing, 9-discharge end casing, 10-bolt; 11-combined type discharging screening plant, 12-slide shoe bearing lining tile, 13-thermal insulating coating.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done and to be further described.
Be illustrated in figure 1 as the structural representation of the two crawler shoe slag mills of the utility model; As shown in the figure; The cylindrical shell 1 of slag mill be a cylindrical shape, is supported by two slipper shoes bodies 2 of the right and left, and feed end rolling ring 3 and discharge end rolling ring 4 all contact with slipper shoes body 2 through the slide shoe bearing lining tile 12 that is in slipper shoes body 2 tops; Slide shoe bearing lining tile 12 is the babbit manufacturing, and the temperature range that babbit is suitable for is lower.
