Abstract
The present invention provides a kind of encapsulating method of closed-smelting machine rotor, puts into rubber composition in mixer before the installation of mixing machine equipment comes into operation or after mixer overhaul of the equipments, after mixing, equipment formally comes into operation again；The composition of the rubber composition are as follows: butadiene rubber 90-110 parts by weight；Zinc oxide 8-12 parts by weight；TDAE environment protection oil 20-30 parts by weight；Specific mixing method are as follows: butadiene rubber is first all put into mixer mixing 1-3min to be kneaded at a slow speed in 25-35rpm by whole process, it is ensured that sizing material is smashed, and 5 addition environment protection oils are then divided, and the 1/5 of total amount is added every time, is kneaded 0.5-1 minutes every time；Dumping when being eventually adding zinc oxide, then being kneaded to 150-170 DEG C.The present invention carries out the sealing of closed-smelting machine rotor from technique, and method is simple, does not need to improve equipment, practical；It can achieve the effect that liquid sealant, dissolve each other with the sizing material of tire plant, will not influence the properties of rubber of later period mixing, it is at low cost, convenient for promoting.
Description
Technical field
The invention belongs to technical field of sealing technology, and in particular to a kind of encapsulating method of closed-smelting machine rotor.
Background technique
Leakproofness is to measure an important indicator of mixer performance, and the rotor end sealing of mixer is in sealing system
Key position, maintenance and to improve sealing effect be important topic on equipment management and equipment and technology.The end face of mixer is close
Bad to the sealing effect of powder and excessive paste is too many in actual operation for seal apparatus, makes to plant maintenance and maintenance
At constant.
Scientific worker constantly improves the sealing performance of mixer, such as application No. is 2004100167824 China
Patent discloses a kind of leak stoppage device of mixer, and application No. is 2009200157445 Chinese patents to disclose a kind of mixing
Machine mechanical end surface seal device.These current improved thoughs are improved from equipment, and improved difficulty is bigger,
Realize that difficulty is also bigger, sealing effect is affected by mechanical part, as the abrasion of equipment is it is possible that unstable
The case where, enterprise needs to purchase new equipment or components, generates additional cost, and it is big to promote difficulty.
Summary of the invention
It is replacing apparatus or components, at high cost, effect for the existing method for improving sealer rotor seal performance
The unstable above problem of fruit, the present invention provide a kind of encapsulating method of closed-smelting machine rotor, and this method solves close from technique
The sealing problem of mill rotor does not need more exchange device or purchases components, so that it may realize good sealing performance, and should
Method is simple, does not influence the properties of rubber of later period mixing, and the waste of raw material, not at low cost, convenient for promoting.
The present invention is achieved by the following technical solutions:
A kind of encapsulating method of closed-smelting machine rotor, comprising the following steps: mixing machine equipment installation come into operation before or mixer
Rubber composition is put into mixer after overhaul of the equipments, after mixing, equipment formally comes into operation again；
The composition of the rubber composition are as follows: butadiene rubber 90-110 parts by weight；Zinc oxide 8-12 parts by weight；TDAE environmental protection
Oily 20-30 parts by weight；
Specific mixing method are as follows: whole process in 25-35rpm to be kneaded at a slow speed, first by butadiene rubber all investment mixings
Machine is kneaded 1-3min, it is ensured that sizing material is smashed, and 5 addition environment protection oils are then divided, and the 1/5 of total amount is added every time, is kneaded 0.5-1 every time
Minute；Dumping when being eventually adding zinc oxide, then being kneaded to 150-170 DEG C.
Further, 100 parts by weight of butadiene rubber of the rubber composition；10 parts by weight of zinc oxide；TDAE environment protection oil
25 parts by weight.
Further, the specific mixing method are as follows: whole process is first complete by butadiene rubber to be kneaded at a slow speed in 30rpm
Portion puts into mixer mixing 1min, it is ensured that sizing material is smashed, and 5 addition environment protection oils are then divided, and the 1/5 of total amount is added every time, every time
It is kneaded half a minute；Dumping when being eventually adding zinc oxide, then being kneaded to 160 DEG C.
Beneficial effects of the present invention: (1) present invention carries out the sealing of closed-smelting machine rotor from technique, and method is simple, is not required to
Equipment is improved, it is practical；(2) rubber composition can achieve the effect that liquid sealant, use with tire plant
Sizing material dissolve each other, will not influence the properties of rubber of later period mixing, and do not influence sealing effect；The rubber composition can be filled and led up
Seal clearance is not present in the concave face of equipment, and leakage problem is not present；(3) rubber composition can be kneaded into sealing in mixer
Glue, sealant are entered in the early stage in the gap of rotor end-face, are effectively sealed to realize to mixer, the later period formally throws
After entering use, sizing material powder can be effectively sealed.
