Abstract
The utility model relates to an adjusting device of a rotary drum dryer, in particular to an adjusting device of concentricity between the rotary drum dryer and two rolling rings, and aims at solving the problem that slipping phenomena appear between base plates and bolts of a traditional rotary drum dryer and the rotary drum dryer. The adjusting device comprises drum body reinforcing rings which have reinforcing effect on a drum body, and further comprises rolling rings, base plates, adjusting bolts, adjusting nuts and fixed plates, wherein the fixed plates are fixedly arranged on the outer circumference of each drum body reinforcing ring at equal intervals, the rolling rings are installed at the central positions of the drum body reinforcing rings in a sleeved mode, fixed holes are arranged in the rolling rings at equal intervals, the base plates are fixedly connected with the fixed plates through the adjusting bolts and the adjusting nuts after penetrating through the fixed holes. According to the adjusting device of the concentricity of the rotary drum dryer, the service life of the dryer is greatly prolonged, difficulty of adjustment of the concentricity between the rolling rings and the drum body of the rotary drum dryer in a dryer production process is reduced, and the manufacturing period of the dryer is shortened.
Description
Technical field
The utility model relates to a kind of adjusting device of roller drying machine, is specifically related to the concentricity adjusting device between a kind of roller drying machine and two rolling rings, has solved the phenomenon of skidding between traditional roller drying machine backing plate bolt and the roller drying machine.
Background technology
At present, along with the development of modern industry, people are increasing to the demand of dryer, and particularly roller drying machine has on industry, chemical industry, mine very widely and uses.When utilizing roller drying machine to produce, the quality of roller drying machine must have influence on the output of material, the not all right profit that directly has influence on the client of output.Roller drying machine is a section welding behind the circle that changes into of steel plate, but this each circle can not be at same center line in processing and welding, what all can have some deviations, these deviations will inevitably cause beating of dryer and swing, and will reduce like this service life of dryer.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art and provides a kind of mode of backing plate that adopts to adjust the cylinder of roller drying machine and the adjusting device of the concentricity between the rolling ring.
The purpose of this utility model is achieved in that
A kind of roller drying machine concentricity adjusting device, comprise cylindrical shell is played the cylindrical shell fixing collar that reinforcement effect is crossed, also comprise rolling ring, backing plate, adjustment bolt, adjusting nut, fixed head, the equidistant fixed and arranged of described fixed head is at cylindrical shell fixing collar excircle, described rolling ring is sleeved on cylindrical shell fixing collar centre, equidistantly be furnished with fixing hole in the described rolling ring, described backing plate is fixedly connected with fixed head by adjustment bolt, adjusting nut after passing fixing hole.
Described fixed head passes through the mode equidistant placement of welding at cylindrical shell fixing collar excircle.
The two ends of described backing plate, fixed head are provided with the bolt hole corresponding with adjusting bolt, the middle part of described backing plate is provided with can the groove shape structure of spiral-lock in fixing hole, and described groove shape structure one lateral edges is provided with a projection that can buckle at the fixing hole oral area.
The described number that is arranged on the bolt hole on backing plate, the fixed head is two or four.
The utlity model has following advantage:
1, the roller drying machine concentricity adjusting device is adjustable backing board structure.The size of fixed head is less times greater than the appearance and size of backing plate, fixedly be by equal portions be welded to uniformly first the roller drying machine anchor ear in the heart, be inserted in afterwards rolling ring, make the width center of the width center of its rolling ring and anchor ear on same straight line, each fixed head above put into backing plate thereafter, backing plate reply misplug enters, can control rolling ring just in time can not slidably reciprocate at the roller drying machine anchor ear like this, at last on will be in advance the adjustment bolt of nut to penetrate backing plate be in the silk hole, make the other end of adjusting bolt what be placed in fixed head is on the hole, well it is fixed up, in cylindrical shell, does not skid.
2, the utility model roller drying machine concentricity adjusting device, the service life of greatly having improved dryer, reduced dryer produce in the difficulty adjusted of concentricity between the cylindrical shell of rolling ring and roller drying machine, shortened the cycle of dryer in the time of making.

The specific embodiment
The utility model will be further described below in conjunction with concrete embodiment.
Shown in Fig. 1,2,3,5, a kind of roller drying machine concentricity adjusting device, comprise cylindrical shell is played the cylindrical shell fixing collar 6 that reinforcement effect is crossed, also comprise rolling ring 1, backing plate 2, adjust bolt 3, adjusting nut 4, fixed head 5, described fixed head 5 equidistant fixed and arranged are at cylindrical shell fixing collar 6 excircles, described rolling ring 1 is sleeved on cylindrical shell fixing collar 6 centres, equidistantly be furnished with fixing hole 7 in the described rolling ring 1, described backing plate 2 is fixedly connected with fixed head 5 by adjustment bolt 3, adjusting nut 4 after passing fixing hole 7.
Described fixed head 5 passes through the mode equidistant placement of welding at cylindrical shell fixing collar 6 excircles.
As shown in Figure 4, the two ends of described backing plate 2, fixed head 5 are provided with the bolt hole 2-1 corresponding with adjusting bolt 3, the middle part of described backing plate 2 is provided with can the groove shape structure 2-2 of spiral-lock in fixing hole 7, and described groove shape structure 2-2 one lateral edges is provided with a protruding 2-3 that can buckle at fixing hole 7 oral areas.
The described number that is arranged on the bolt hole 2-1 on backing plate 2, the fixed head 5 is two or four.
The operation principle of this utility model is as follows:
Roller drying machine drum body 6 is in butt welding, in the time of general docking welding of all returning owing to cylinder because being out of shape can appear in the reason of expanding with heat and contract with cold, add in addition cylinder turn round in, the phenomenon that also can occur not justifying, yet the backing plate 2 in the roller drying machine concentricity adjusting device is exactly to utilize adjustment bolt 3 to adjust the cylindrical shell 6 of bottom roll dryer to distance between the roller drying machine rolling ring 1, roller drying machine can not swung when rotating, just can rotate adjusting nut 3 and adjust roller drying machine rolling ring 1 and roller drying machine drum body 6 distances if find the roller drying machine swing, roller drying machine be swung reduce to minimum.
