Abstract
The invention discloses a kind of pelleter rotary drum, belong to pelleter technical field.Purpose is that solve vulcanized sodium, NaHS in the prior art and sulphur pelleter rotary drum short life, cost be high, ropy defect.The rotary drum of the present invention includes rotary drum body, the rotary drum body surface chromium plating.Had using the pelleter rotary drum of the present invention and improve vulcanized sodium product quality, good environmental protection；Increase rotary drum service life；Save pelleter O＆M cost；The advantages that improving pelleter cooling efficiency.
Description
Technical field
Present invention relates particularly to a kind of pelleter rotary drum, belong to pelleter technical field.
Background technology
Pelleter is called slicer, scraping machine etc., and conventional vulcanization sodium, NaHS and sulphur pelleter rotary drum used
HT200 or HT250 and 0Cr25Ni20 (310S), HT are the meanings of grey cast-iron, and the thermal conductivity of grey cast-iron is relatively good, is not easy
Deformation.But this material will be rolled into the shape of rotary drum, may not technically.Several big part assemblings are made,
But this creates the terminal the difficulty of built-in cooling system repeated disassembled and assembled, and rotary drum decentraction is caused, blade is destroyed drum surface,
Meanwhile institute's dress cooling system material is carbon steel, the time is not long easily by aqueous corrosion, it is necessary to change.At present, it is small-scale to some
Producer also temporarily uses this scheme, but is phased out.
In the prior art, there is a kind of vulcanized sodium pelleter for being used to produce to employ stainless steel as facestock, do not plate
Chromium, stainless steel is due to softer, and after 1 year, rotary drum has not been regular circular, causes blade and rotary drum friction, surface is because of knife
Piece and scratch out many grooves.
The content of the invention
Therefore, for the above-mentioned deficiency of prior art, pelleter rotary drum of the invention is proposed.
Specifically, pelleter rotary drum provided by the invention includes rotary drum body, the rotary drum body surface chromium plating.
Further, the rotary drum body is made up of Q345B low-alloy steel.
Further, the pelleter is vulcanized sodium pelleter, NaHS pelleter or sulphur pelleter.
Chromium is plated to drum surface except chromium plating, can also be that one kind allows drum surface to cover chromium by chromium spraying technology
The alternative solution of layer.
The beneficial effects of the present invention are：Pelleter rotary drum proposed by the present invention, be particularly suitable for use in vulcanized sodium pelleter, sulphur
Sodium hydride pelleter or sulphur pelleter have advantages below compared with existing pelleter rotary drum：
1st, vulcanized sodium product quality, good environmental protection are improved
For production low-iron sodium sulfide, (the vulcanized sodium ferro element that guarantee is produced is in below 30ppm, purposes ratio for some producers
Conventional vulcanization sodium is more extensive) a kind of material that must not use then, but this material have one it is fatal the shortcomings that, i.e., hardness is relatively low.
Worker in operation easily contacts blade with transferring shares, and drum surface is scraped off quickly, surface becomes coarse so that alkali is being transferred shares
Surface is more firm, and scraping blade gets off highly difficult, and powder is more in finished product.
2nd, rotary drum service life is increased
Common three months rotary drums of pelleter are just scraped.Using the rotary drum life-span of invention at 1 to two years or so.Compare
For, it is not necessary to standby rotary drum.Typically only need equipment gear, blade.
3rd, pelleter O＆M cost is saved
The corrosion-resistant heatproof of chromium, it is very smooth after the polishing of surface, alkali can be made to be easy to, and alkali is equal without powder, sheet size
It is even, it can realize that automatic machine is packed substantially, save blade, many expenses can be saved.
4th, pelleter cooling efficiency is improved
The core operating principle of pelleter is by spraying cooling system in rotary drum, reduces and melts to surrounding spray cooling water
The temperature of alkali, is allowed to cool, solidification, eventually through blade dicing.But due to some factories in order to prevent vulcanized sodium, sulphur hydrogenation
Sodium corrosion rotary drum, have no alternative but using stainless steel as drum surface.And stainless steel is although corrosion-resistant, but thermal conductivity factor is poor, drop
Temp effect unobvious.After chrome-plated process, our pelleter can use manganese steel, and chromium plating does not influence cooling-down effect, heat conduction
Coefficient is preferable, improves cooling efficiency, has ensured the quality of product.
Brief description of the drawings
Fig. 1 is the pelleter schematic diagram in embodiment；
Fig. 2 is the front view of pelleter rotary drum in embodiment；
Fig. 3 is Fig. 2 left view.
Reference is as follows：
1st, rotary drum, 2, scraper, 3, charging tray, 4, charging aperture, 5, chromium coating, 6, spraying cooling water, 7, compressed air, 8, axle.
Embodiment
The embodiment of the present invention is illustrated below in conjunction with the accompanying drawings：
In the present embodiment, rotary drum is applied to vulcanized sodium/NaHS/sulphur pelleter, and its operation principle is as shown in Figure 1.
Each part includes rotary drum 1, scraper 2, charging tray 3, charging aperture 4, chromium coating 5, spraying cooling water 6, compressed air 7 in Fig. 1.
Vulcanized sodium/NaHS/sulphur pelleter is substantially the rotary machine of a continuous coo1ing film-making, and pelleter is in work
When making, rotary drum 1 immerses 10-20mm in lye dissolving tank.Rotary drum 1 leaves molten caustic soda just in one layer of 0.6-1.2mm thickness of its adsorption
Alkali lye, and crystal is condensed into, enter rotary drum 1 and cooled down, and be finally reached 60 DEG C.Then by device for scraping --- scraper 2 reams.And turn
Drum is the core component of akali sulphide/NaHS pelleter.
As shown in Figure 2 and Figure 3, Fig. 2 includes rotating shaft 8 to the rotary drum of the present embodiment, in the pelleter rotary drum 1 of production, be
Enhancing service life, we with the addition of chromium coating 5 to the surface of rotary drum 1.Chromium and vulcanized sodium, NaHS, sulfur melting alkali are not
It can chemically react, and be adsorbed in drum surface so that together with the manganese steel material of pelleter rotary drum is formed between molten caustic soda
Isolation.
And chromium plating for convenience, by rotary drum body material selection it is Q345B low-alloy steel in the present embodiment, also known as manganese steel,
This material has the characteristics of wear-resisting, hardness is high simultaneously.Pelleter is non-standard equipment, specific thickness according to the actual requirements depending on.
Described above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, on the premise of principle of the present invention is not departed from, some improvements and modifications can also be made, these improvements and modifications
It should be regarded as protection scope of the present invention.
