Abstract
The utility model discloses a wastewater treatment chain which is formed by connecting multiple chain links. Each chain link is formed by fixedly connecting two inner chain plates and a sleeve in a clearance fit manner and arranging a rotating roller on the sleeve in a sleeved manner, wherein the roller is formed by one-step casting molding of high-chromium cast iron and the sleeve is made through the heat treatment process of a thick infiltrated layer of 20CrMo material. Each two chain links are connected through two outer chain plates and a pin, the pin is penetratingly arranged in the corresponding sleeve, two ends of the pin penetrate through the outer chain plates to be fixed through a stop part, and the pins are processed by subjecting 42CrMo material to integral quenching and tempering prior to heat treatment. The rollers are made of the high-chromium cast iron to realize small abrasion and no corrosion of the rollers in complex environments with slurry and corrosion, so that transmission stability is improved and the service life of the chain is prolonged. Parts of the wastewater treatment chain are all made of high-quality alloy steel material, '8'-shaped chain plates are adjusted into straight-sided chain plates, the diameter of the pins is increased, and machining processes of the parts are changed greatly.
Description
Technical field
The utility model relates to a kind of transmission chain bar, particularly a kind of sewage treatment chain.
Background technique
The sewage treatment chain is used for sewage treatment, and working environment has the various complicated situations such as burn into mud.Lubricate owing to can not get so chain is in operation, and also have corrosive deposit, also can't carry out the maintenance of chain, this is just to the higher requirement of chain proposition.
Chain is operating critical component, directly affects the operational efficiency of complete equipment working life, because roller etc. is not wear-resisting, uses not ideal enoughly, irregularly shuts down and overhauls replacing, affects the operational efficiency of complete equipment.
The model utility content
The utility model has overcome above-mentioned the deficiencies in the prior art, and a kind of wear resistant corrosion resistant is provided, and has reduced the sewage treatment chain of maintenance probability, satisfies the long-life usage requirement of sewage disposal device.
The technical solution of the utility model is achieved in that
A kind of sewage treatment chain is to be formed by connecting by a plurality of chain links, the consisting of of single chain link: two inner plates are fixedly connected with the sleeve interference fit, and the roller of sheathed rotation on sleeve, roller are to adopt the moulding of rich chromium cast iron one-step casting; Sleeve is to adopt the 20CrMo material to make through the heat treatment process of thick infiltration layer; Be connected with bearing pin by two outer plates between chain link, bearing pin is arranged in sleeve and the two ends of bearing pin are run through outer plate and fixed by retainer; Bearing pin is to adopt 42CrMo material high frequency heat processing after integral body is modified to make.
As preferably, lock pin or cubic die till described retainer.
Adopted the beneficial effects of the utility model of technique scheme to be:
Part material of the present utility model all adopts the high duty alloy Steel material, carrier bar is adjusted into straightsided shape by 8-shaped, strengthened pin diameter, and the processing technology of part has also had larger change, roller adopts high chromium cast iron material, by the precision casting processing technology, to realize roller less wear and not corroding in the complex environment that mud and corrosion are arranged, improve transmission stability, extend chain working life; Sleeve is the 20CrMo material, adopts the heat treatment process of thick infiltration layer, to guarantee intensity and the toughness of part; Bearing pin adopts the high frequency heat treatment process processing again after integral body is modified of 42CrMo material, when guaranteeing bearing pin toughness, improves surface hardness and the wear resistance of bearing pin, better meets usage requirement.
