1.2  Basic construction and configuration of equipment

The rotary-type cooler is the cooling tools of oxide pellet that is compatible with rotary kiln. The powerful cooling spot of this rotary-variety cooler is 50 mtwo. The rotary course of the trolley is clockwise and its medium diameter is φ12.5 m and its successful width is 1.eight m. The rotary-sort cooler has two sets of driving gears and its functioning system is steady obligation.

The rotary-sort cooler can be divided into 3 sections and chambers. A partition is set in between one particular area and one more. The rotary-variety cooler is mostly made up of the transmission equipment, rotary components, the facet block roller, the feed hopper, the hood, bellows, the hood in the discharge zone, the discharge unit and double-decked cinder valve and so on.

The rotary areas are made up of the rotary framework, the trolley, the roller arm of the trolley and the chain bracket. The trolley is created of particular heat-resistant metal and linked to the rotary framework by axis.

Nine bellows of the rotary-kind cooler are set up on the generator bracket. The seal of bellows and turning frameworks shall adopt rubber friction seal. Guide regulating valves are established between bellows connected by two adjacent air blowers. The cinder valves of double gravity are set below bellows in buy to discharge balk cargo in the bellows.

The feed hopper is made up of the hopper, the partition and the fat for leveling materials with the bearing on the platform of civil engineering. The bodyweight for leveling materials in the feed hopper can hold the top of the trolley's batch layer in the designed height and its content is ZGCr25Ni20NmoRe. The ore-dumping hopper is manufactured by welding steel plate and shaped metal and its inside is geared up with dress in-resistant plate to avoid the use and tear of the hopper caused by materiel and provides.

The transmission equipment of the rotary-variety cooler has twin drives and is made up of electric machinery, decelerator, coupling, travel platform and so on. The push rail is utilised for limiting the reversal of the trolley and guiding the direction of the trolley having been discharged. The straight rail and curved rail are manufactured of wear-resistant material. The mounted display is established in the head hood of the rotary kiln with the content being ZGCr25Ni20NmoRe.

The rotary-sort cooler shall meet up with the subsequent basic complex demands: it shall adopt reliable static and dynamic seal strategy it shall undertake effective measures to solve the segregation of the radial particle size of the fabric it shall be geared up with two sets of transmission gears and its principal driving motor shall be in charge of frequency handle its measuring pocket shall remedy the fabric's unevenness it shall remedy the dilemma of the off-tracking of the rotary kiln's frameworks it shall solve the enjoy and fumble between trolley and trolley, as well as in between trolley and framework it shall also remedy the problems that the bodyweight for leveling is unsatisfactory in materials and form, has reduced existence span and numerous breakdowns it shall solve the material difficulty of mounted display screen it shall also fix the transformation of the stainless steel plate partition among cooling sections It shall also remedy the problems of lower lifestyle span of striker plate.

three  Equipment production specifications and inspection expectations

  3.1 Rotary-kind cooler manufacturing requirements and inspection specifications drawings, concluded by Vendor, shall topic to Buyer's review and signing. Only right after that, can this drawing be adopted for producing. This kind of operates as assembling, test and inspection are then executed in the production plant.
3.1.two Rust protection and coating should performed in accordance to layout prerequisite. Production, assembling and commissioning of the rotary-sort cooler should meet up with the needs of design and style drawings and documents and be provided with full top quality inspection stories. Supervisors for gear producing are entitled to verify and overview top quality inspection reviews and related documents.
3.1.four Main CZPT CZPT for Manufacture and Inspection:

three.2 Manufacture and Inspection Necessity for Primary Part of Circular Cooler

three.two.1 Frame and Transmission Assist
Use H-formed or other shaped steel to manufacture the column, beam and bracing of frame and transmission support weld the tiny variety of certain H-formed steel promise the welded H-shaped metal comply with the provision in YB3301-92 and get shaping following welding.
Guarantee the verticality shaped by upright column and its centre line as required by drawing and the assembly accuracy of frame as necessary by style.
three.two.2Rotating Body and Trolley
Units of rotating frame are related by bolt and hinge bolt. Concentricity of two concentric shafts on inner and outer beams of rotating frame shall satisfy the tolerance prerequisite. Remove the internal stress of rotating frame right after welding get device tooling take ultrasonic tests on major weld line related to structural toughness as necessary by drawing assure the quality of weld line no decrease than quality-II in GB/T3323-1987. Use the bent normal metal rail as the monitor of rotating frame.
Trolley is created of special heat-resistant metal, whose mechanical property, chemical composition, spheroidization rate and device elongation shall comply with the provision of style. Shaft gap of trolley is essential to bore via after.
3.two.3 Pressure Observe and Aspect Keep track of
