Abstract
The utility model relates to a miniaturized dry coke quenching rotary seal valve sets up the rotary seal valve housing on a support, ann has bearing room and a rotor shaft on the casing end cover, and casing one side sets up a distributor, this distributor through the copper pipe with connect get into that the casing insidely moves, quiet ring junction and bearing room, the distributor passes through the copper pipe and connects the bearing room, again by the play oil pipe of bearing room insert again move, the lubrication conduit of quiet annular one -tenth constitutes a confined lubricating system. Because of entire system is the confined, lubricating grease is at inside cyclic utilization, and the waste of having stopped the material inside the unable logging in of external dust, makes the bearing have a good operating environment, and in the life -span of having improved the bearing greatly, it normally goes on smoothly to have guaranteed that production is long -term, has reduced manufacturing cost.
Description
Technical field
This utility model belongs to metallurgy industry technical field, is the key equipment of coke-oven plant's dry coke quenching link.
Background technology
Due to large-scale dry quenching system there is difficult in maintenance, maintenance cycle length, impact produces big problem, many coke-oven plants are to miniaturization, how supporting development.But according to investigations, balanced coke discharging equipment (rotary seal valve) regular in the market is all large-scale (75-260T), there is no regular small-sized rotary seal valve, only some coarse original device, not only fault rate is high, and the life-span is very short, has a strong impact on the normal of coke-oven plant and produced and economic benefit.
For case above, we have developed novel miniaturization equilibrium coke discharging equipment 10T rotary seal valve.This equipment, with brand-new design concept, adopts multinomial advanced technology, has many advantages compared with same category of device on market, and performance comparison is following table such as:
Summary of the invention
The purpose of this utility model is a kind of balanced coke discharging equipment 10T rotary seal valve of exploitation, fills up that this tonnage domestic is regular, the blank of professional rotary seal valve.
The technical solution of the utility model is: arrange rotatory sealing valve housing on a support, housing two ends are end cap, end cap is equipped with bearing chamber and armature spindle, housing upper arranges charging aperture, bottom arranges discharging opening, it is characterized in that, housing side arranges an allotter, this allotter enters the dynamic and static engagement of loops place of enclosure interior and bearing chamber by copper pipe and joint, allotter by copper pipe and joint, then is accessed again the lubricating pipe that dynamic and static ring formed and constitutes the lubricating system of a closing after bearing chamber by the flowline of bearing chamber.
The beneficial effects of the utility model: this equipment is novel miniaturization equilibrium coke discharging equipment 10T rotary seal valve.Its peculiar bright spot is:
1. single distribution is closed to grease lubrication system, and other similar products are multiple dispenser open systems.
2. main shaft bearing adopts self-aligning roller bearing.Other similar products are radial ball bearings.
3. rotor high-abrasive material is special high-quality pottery.Other similar products are wear-resisting steel plates.
4. best rotor and housing fit clearance and guarantee technique.
Because whole system is to close, grease utilizes in inner loop, has stopped the waste of material, external dust cannot be introduced into internal system, makes bearing have a good running environment, substantially increases the life-span of bearing, ensure that long-term being normally smoothed out of production, reduce production cost.
This equipment is according to discharging standards, through careful design and test, draw the best clearance of rotor and housing, rotor outer circle, housing inner circle are adopted mach mode, ensure that the accuracy in gap, stability, concordance, thus ensureing that every equipment all meets discharging standards.
Accompanying drawing explanation
Fig. 1 is this utility model architecture front-side face schematic diagram.
Fig. 2 is this utility model structure back side face schematic diagram.
Detailed description of the invention
This utility model, such as shown in accompanying drawing 1, accompanying drawing 2, arranges rotatory sealing valve housing 2 on a support 1, and housing 2 two ends are end cap 3, and end cap 3 is equipped with bearing chamber 4 and armature spindle 6, and housing 1 top arranges charging aperture 5, and bottom arranges discharging opening 7.
This equipment is characterised by, housing 1 side arranges an allotter 8, this allotter 8 enters the internal dynamic and static engagement of loops place of housing 1 and bearing chamber 4 by copper pipe 9 and joint 10, allotter 8 is by copper pipe 9 and joint 10 to bearing chamber 4, then is accessed again the lubricating pipe that dynamic and static ring formed by the flowline 11 of bearing chamber 4 and constitute the lubricating system of a closing.As a comparison, other similar devices are that system is controlled by two or more allotters, and the flowline of bearing chamber is opened in outside system, export and communicate with the external world.
This feature has the advantages that:
Legacy equipment allotter quantity is many, which increases because of the fault rate of allotter problem；Oil pipe is open, and in operation, grease is ceaselessly discharged, and year in year out, the waste caused is well imagined；Coke-oven plant is many dust atmospheres, and the oil pipe mouth of legacy equipment communicates with the external world, and dust constantly enters bearing chamber, infringement bearing, even causes stuck, causes the inefficacy sealing valve, have to stopping production overhaul, and the cycle keeped in repair is long, brings immeasurable loss to coke-oven plant.
1. we are calculated and test repeatedly by careful, invent single allotter closed to grease lubrication system (mainly include the model specification of allotter, the layout etc. of the Position Design of oil drop, pipeline is determined, flowed to intrasystem pressure), decrease the fault occurred because of allotter problem；Because whole system is to close, grease utilizes in inner loop, has stopped the waste of material, external dust cannot be introduced into internal system, makes bearing have a good running environment, substantially increases the life-span of bearing, ensure that long-term being normally smoothed out of production, reduce production cost.
2. legacy equipment main shaft bearing is radial ball bearing, does not have aligning function, is not easy to assembling, and main shaft likely can exist stress and concentrate, and the of long duration fatigue that there will be causes fracture.
For case above, the novel device of our design adopts self-aligning roller bearing, has self-aligning function, is not only easy to assembling, and runs smooth and easy, does not have problem of stress concentration, it is ensured that the knowability of main shaft, persistency.
3. the rotor high-abrasive material of legacy equipment is wear-resisting steel plate, although have certain wearability, but corrosion resistance is poor, and containing sour gas in coal gas, is corrosive, and the steel plate life-span is short.
For this, the novel device rotor of our design adopts dedicated ceramic high-abrasive material, and not only wearability is good, and, corrosion resistance is very strong, and the life-span is long.
4. for sealing valve, the gap of rotor and housing is a key parameter, and excesssive gap does not reach discharging standards, and gap is too small, easily stuck during operating, catastrophe failure occurs.
Legacy equipment is to adopt rotor built-up welding, and the mode of defensive position mill, therefore, rotor is unstable, inconsistent with the gap of housing, irregular, it is difficult to ensure country's emission request.
The novel device of our design, according to discharging standards, through careful design and test, draw the best clearance of rotor and housing, rotor outer circle, housing inner circle are adopted mach mode, ensure that the accuracy in gap, stability, concordance, thus ensureing that every equipment all meets discharging standards.
