Description
Technical field
The utility model relates to a kind of protective devices of alkali recovery furnace electrostatic precipitator lower part scrapper conveyor, in particular to a kind of
The protective device of alkali recovery furnace electrostatic precipitator lower part scratch board machine chain.
Background technique
In the industrial production, alkali recovery furnace has its particularity, and electric precipitation collects a large amount of sode ash dust, and ash properties are led
Electrically by force, light weight, corrosivity are strong.Therefore the scrapper conveyor shape and feature of its underpart collection ash content and coal burning boiler have larger area
Not, it is larger to receive grey area, is essentially identical to electric precipitation cross section, uses double driving chain, and in double driving chain
Upper interval installation conveying scraper plate receives grey scraper plate as electric precipitation lower part and conveys sode ash, and star drive chain is installed at drive shaft both ends respectively
Wheel, the part double wedge of two sprocket wheels are engaged with chain, in external drive motors starting, drive drive shaft and driving chain whole
Operation is played the role of receiving ash conveying sode ash so that scraper plate be driven to run together.
In scrapper conveyor During Process of Long-term Operation, chain will appear burn into deformation, relaxation.Thus make the guided way of chain
Bearing load is increased and is deformed, and will lead in the process of running if guided way is inserted into lower arrayed chain item under deformation
Chain and driving motor load surcharge, so as to cause chain breakage, driving motor damage, scraper plate is severely deformed, ash conveying device damage
The accidents such as bad.It also will cause entire alkali recovery furnace parking when the scrapper conveyor well damage of alkali recovery furnace electric precipitation lower part.
Utility model content
Technical problem to be solved by the utility model is: providing a kind of guarantor of alkali recovery furnace electrostatic precipitator lower part scrapper conveyor
Protection unit, to solve the problems, such as to be caught in chain damage equipment in lower part because of guided way bearing load excessive deformation.
The technical solution of the utility model is: a kind of protective device of alkali recovery furnace electrostatic precipitator lower part scrapper conveyor, packet
It includes: top chain, lower part chain, the sprocket wheel for driving top chain and lower part chain to walk and being used to support chain
Guided way with curved portion, guided way are higher than sprocket wheel, have gap between the curved portion and sprocket wheel of guided way, in the guiding
The anti-snap-gauge extended to sprocket wheel direction is equipped on the outside of the curved portion of rail, the width dimensions of anti-snap-gauge are big compared with the width dimensions of chain,
The bottom position of anti-snap-gauge is low compared with guided way curved portion bottom position.
The anti-snap-gauge is arc panel, and the center of circle and the center of circle of guided way curved portion are ipsilateral.
The anti-snap-gauge is connected to the end side of guided way curved portion.
The anti-snap-gauge is square steel, surface hardness HRC55.
The guided way is square steel, surface hardness HRC55.
The anti-snap-gauge is curved plate.
Compared with prior art, the utility model on alkali collection electric precipitator lower part scratch board machine chain guide rail top by pacifying
Fill anti-snap-gauge, can effectively avoid when guided way bearing load increase, flight chain it is loose when, occur arc-shaped guide rail insertion or card
Firmly the phenomenon that flight chain.To avoid result in chain breakage, driving motor damage, scraper plate is severely deformed, ash conveying device damage
Etc. accidents occur.
The utility model can also be applied in other chemical processes for having similar chain drive, have well promote and
Use value.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the top view of guided way and anti-clamp structure in Fig. 1；
Description of symbols: 1 guided way, 2 anti-snap-gauges, 3 sprocket wheels, 4 top chains, 5 lower part chains, 6 curved portions.
Specific embodiment
With reference to the accompanying drawing and utility model is described further in specific embodiment:
With reference to Fig. 1 and Fig. 2, filled according to a kind of protection of alkali recovery furnace electrostatic precipitator of the utility model lower part scrapper conveyor
Set, scrapper conveyor is mainly made of top chain 4, lower part chain 5, sprocket wheel 3 and guided way 1, middle sprocket 3 respectively with top chain
4 and lower part chain 5 be engaged, for driving top chain 4 and lower part chain 5 to walk, guided way 1 is used to support top chain, and
Play the role of guiding.Top chain 4 and lower part chain 5 under the drive of sprocket wheel 3, drive scraper plate along electric precipitation bottom forward
It is mobile, play the role of collecting sode ash.Operation (by taking Fig. 1 as an example), chain-driving scraper plate are upward from bottom clockwise for sprocket wheel 3 simultaneously
Layer operation, in the process of running, chain are bonded the operation of 1 outer of guided way, prevent chain from deviating.Guided way 1 has close to sprocket wheel side
There is curved portion 6, since guided way 1 is higher than sprocket wheel 3, and has certain gap between them, therefore this kind of structure can be convenient chain
The normal walking of item.
The anti-snap-gauge 2 that oriented 3 direction of sprocket wheel extends, the broad-ruler of anti-snap-gauge 2 are installed on the outside of the curved portion 6 of guided way 1
Very little big compared with the width dimensions of chain, the bottom position of anti-snap-gauge 2 is low compared with guided way 1 curved portion, 6 bottom positions, so works as guided way
1 bearing load increase, flight chain is loose tilt down when, chain smoothly transits to chain by the supporting role of anti-snap-gauge 2
On wheel 3 or its barrier effect, the insertion of 1 end of guided way can be avoided or the phenomenon that block flight chain, to avoid result in
Chain breakage, driving motor damage, scraper plate is severely deformed, and the accidents such as ash conveying device damage occur.
Preferably, anti-snap-gauge 2 is arc panel, and the center of circle and the center of circle of 1 curved portion 6 of guided way are ipsilateral, can be minimized pair
The influence of chain normal walking.Anti- snap-gauge 2 is connected to the end side of 1 curved portion 6 of guided way, is preferably connected by welding manner.It is excellent
Selection of land, guided way 1 use section for the square steel of 29mm*29mm, and carry out surface hardening, its surface hardness reaches after heat treatment
HRC55, to improve its service life.Anti- snap-gauge 2 selects curved plate, with a thickness of 5mm, width 150mm.
It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined
Assert that the specific implementation of the utility model is only limited to these instructions.For the ordinary skill of the utility model technical field
For personnel, without departing from the concept of the premise utility, a number of simple deductions or replacements can also be made, should all regard
To belong to the protection scope of the utility model.
