Description
Technical field
It the utility model is related to material sieving technology field, more particularly to a kind of controllable self-cleaning type roller type sieving machine in real time.
Background technology
Roller type sieving machine is the special equipment for sieving the non-stepped mixing ball that pelletizer excludes, and has been widely used in steel
The industries such as iron, metallurgy and chemical industry, its general principle are by arranged in parallel from high in the end successively and have more of certain interval sieves
Roller rotates and is classified spherical material.
The rotating speed of current roller type sieving machine sieve roller is fixed, due to each not phase of the property of output and screening materials carrying
Together, the roller type sieving machine of fixed rotating speed can not adjust screening efficiency in real time according to the condition of production at that time, be brought to pelletizing production
Very big is passive.It is general at present by the way of sieve roller rotating speed is improved in order to improve screening efficiency, not only increase electric power and disappear
Consume, increase the mechanical wear of sieve roller and drive apparatus, due also to screening efficiency is too high, material when by the sieve roller on top
Through completing to sieve, the sieve roller of bottom is caused to cannot get washing away for new material, debris is easily accumulated in gap, and debris can be accumulated in for a long time
Between sieving roll gap, this part is caused to sieve roller heel and toe wear.
Utility model content
In view of the shortcomings of the prior art, the utility model provides a kind of controllable self-cleaning type roller type sieving machine in real time, can be with
According to the cycle period of how much adjustment cleanings in time of material debris, it is ensured that no-sundries stockpile for a long time between sieve roll gap, extend sieve roller
Service life.
Technical scheme is used by the utility model solves its technical problem：The self-cleaning type roll-type sieve controllable in real time
Extension set includes the motor that every sieve roller of more sieve rollers arranged in parallel successively from high to low and having certain interval and driving rotates, often
Equal attached with frequency converters on the motor of root sieve roller, the frequency converter connect PLC, the frequency of each frequency converter are controlled by PLC program
Rate, the frequency of the frequency converter are changed into high-frequency from normal frequency successively from low to high or become successively by high-frequency from high to low
For normal frequency.
Compared with prior art, the beneficial effect of controllable self-cleaning type roller type sieving machine in real time provided by the utility model
It is：The utility model is realized the real-time controllable of sieve roller rotating speed, reached by the attached with frequency converters on the motor for driving each sieve roller
The regulation at any time of screening efficiency, and the frequency converter is reached sieve roller debris self-cleaning function, improved by PLC control
The whole service life of equipment.
Brief description of the drawings
, below will be to needed for embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
The accompanying drawing to be used is briefly described, it should be apparent that, drawings in the following description are only some realities of the present utility model
Example is applied, for those of ordinary skill in the art, on the premise of not paying creative work, can also be according to these accompanying drawings
Other accompanying drawings are obtained, wherein：
Fig. 1 is the structural representation of controllable self-cleaning type roller type sieving machine in real time provided by the utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only part of the embodiment of the present utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The all other embodiment obtained, belong to the scope of the utility model protection.
Referring to Fig. 1, the controllable self-cleaning type roller type sieving machine 1 in real time includes arranged in parallel successively from high to low and had
The motor 12 that roller rotates is sieved in more sieve rollers 11 of certain interval and driving every, and frequency conversion is installed additional on the motor 12 of every sieve roller 11
Device 13, the frequency converter 13 connect PLC14, and the frequency of each frequency converter 13 is controlled by PLC program.
The specific control process of the PLC14 is：The frequency of the frequency converter 13 is controlled from low to high successively by normal frequency
Rate is changed into high-frequency, improves the rotating speed of relative lower section sieve roller, and debris is acted on because of the different rotating speeds of adjacent two sieve rollers by power
And clear up away, after all sieve rollers 11 are all changed into high-frequency, then control the frequency of the frequency converter 13 from high to low successively by
High-frequency is changed into normal frequency, also with the speed discrepancy of adjacent two sieve rollers, the debris sieved between roller 11 is cleaned out, so as to realize
Debris cleaning circulation between sieve roller, can be according to the cycle periods of how much cleanings of adjustment in time of material debris, it is ensured that sieve roller
No-sundries stockpile for a long time between seam, extend sieve roller service life.
The beneficial effect of controllable self-cleaning type roller type sieving machine 1 in real time provided by the utility model is：The utility model leads to
The attached with frequency converters 13 on the motor 12 for driving each sieve roller 11 is crossed, the real-time controllable of the sieve rotating speed of roller 11 is realized, has reached screening
The regulation at any time of efficiency, and the frequency converter 13 is reached sieve roller debris self-cleaning function, is improved and set by PLC14 control
Standby whole service life.
Embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, it is every
The equivalent structure or equivalent flow conversion made using the utility model description, or directly or indirectly it is used in other phases
The technical field of pass, similarly it is included within scope of patent protection of the present utility model.
