The discharge device for the rotary hearth furnace is simple in structure, easy and convenient to manufacture and long in service life. The discharge device comprises a first water-cooled screw, and is structurally characterized in that a second water-cooled screw corresponds to the first water-cooled screw.
Description
Technical field
The utility model relates to the improvement that a kind of rotary hearth furnace is used water-cooled discharge with endless screw apparatus structure.
Background technology
The characteristics of rotary hearth furnace are that siege rotates, and the relative static and uniformly dispersing with siege of material is on siege, and the bed of material is thinner.Existing discharge is the single-screw discharge, and high-temperature material carries out continuous pulp discharge along with the single-screw blade rotation along the helix direction of advance.
Because the helical structure characteristics easily cause high-temperature material to be scattered to both sides, make discharge unclean.Spiral is operation at high temperature, quick abrasion, and service life is low.When the material grain had bigger variation or helical blade serious wear, material spilling can cause discharge unclean, the inefficient problem of discharge; And when the siege of helical blade and rotary hearth furnace distance was big, residual material was bonded on the siege, and siege is raise, and caused jam to shut down and influenced problem such as the thermal efficiency.
The patent No. is 200810238515.X, and title is " high-temperature material handling spiral ", and it has announced a kind of rotary hearth furnace material handling spiral, and it not only carries out water-cooled to the rotating shaft of spiral in order to improve the service life of spiral, and also the blade to spiral carries out water-cooled; Though can playing to a certain extent, this water-cooling pattern prolongs the spiral purpose in service life,, helical blade to be carried out water-cooled can cause vane thickness excessive, the discharge effect is bad; And, the sealing of helical blade and rotating shaft junction, and the sealing of the water route between the blade all is difficult to realize; This not only increases considerably manufacture difficulty, and economic benefit is low.
In addition, existing spiral water-cooled need customize special swivel joint usually; This has increased production cost, also needs often swivel joint to be carried out maintenance and repair, uses inconvenience.
Summary of the invention
The utility model is exactly at the problems referred to above, provides a kind of simple in structure, is easy to production and processing, long service life, and production and processing is the rotary hearth furnace discharge device easily.
For realizing above-mentioned purpose of the present utility model, adopt following technical scheme, the utility model comprises first water-cooling spiral, its structural feature is provided with second water-cooling spiral with respect to first water-cooling spiral.
As a kind of preferred version of the present utility model, the two ends of described first water-cooling spiral and second water-cooling spiral all are arranged on the lifting platform that links to each other with hydraulic cylinder.
As another kind of preferred version of the present utility model, described first water-cooling spiral and second water-cooling spiral include the hollow shaft with blade, and an end of hollow shaft links to each other with motor, and the other end of hollow shaft is outside equipped with bearings; Hollow shaft supports an end opening place that links to each other with bearing the sealing shroud with water inlet pipe is set; Be provided with fixedly water pipe in the sealing shroud, fixedly an end of water pipe stretches in the hollow shaft, and fixedly the other end of water pipe is delivery port.
The beneficial effects of the utility model: 1, the utility model changes double-helical discharge device into by existing single-screw discharge device, has increased substantially the discharge effect; And, because the double helix discharge device has increased nesting area, can effectively improve production capacity, therefore, first water-cooling spiral and second water-cooling spiral only need adopt 1～2 and get final product, and when reducing material spilling, have also reduced the production difficulty, and be easy to maintenance.
2, the utility model when blade is worn, can descend first water-cooling spiral and second water-cooling spiral by first water-cooling spiral and second water-cooling spiral are arranged on the lifting platform by lifting platform, has remedied the wearing and tearing of blade; Improve service life by this way, can at blade water-cooling structure be set, when reducing spiral production difficulty significantly, the thickness of blade can be reduced to 8～14mm, the discharge smoothness.
In addition, by lifting first water-cooling spiral and second water-cooling spiral, can also adapt to the discharge requirement of different material.
3, the utility model water-cooling structure is simple, reasonable, need not to use swivel joint, and parts can be produced voluntarily, when having reduced cost, have also reduced maintenace point.

The specific embodiment
The utility model comprises first water-cooling spiral 5, is provided with second water-cooling spiral 6 with respect to first water-cooling spiral 5.
The two ends of described first water-cooling spiral 5 and second water-cooling spiral 6 all are arranged on the lifting platform 2 that links to each other with hydraulic cylinder 11.
The side of described first water-cooling spiral 5 or second water-cooling spiral 6 is provided with scraper 7.Scraper 7 can collapse to the material that is scattered first water-cooling spiral 5 or second water-cooling spiral, 6 places, and first water-cooling spiral 5 or second water-cooling spiral 6 can be discharged material smoothly, and scraper 7 plays clear material simultaneously, avoids the siege sizing.
Described scraper 7 is set to the arc toothing, by the arc tooth, can allow the material of suitable size pass through, and avoids jam.
Described scraper 7 also is arranged on the lifting platform 2.Prolong the service life of scraper 7.
Blade 4 thickness of described first water-cooling spiral 5 and second water-cooling spiral 6 are 8～14mm.The discharge smoothness.
Described first water-cooling spiral 5 and second water-cooling spiral 6 include the hollow shaft 3 with blade 4, and an end of hollow shaft 3 links to each other with motor 1, and the other end of hollow shaft 3 is outside equipped with bearings 8; Hollow shaft 3 supports 8 end opening places that link to each other with bearing the sealing shroud 9 with water inlet pipe 13 is set; Be provided with fixedly water pipe 12 in the sealing shroud 9, fixedly an end of water pipe 12 stretches in the hollow shaft 3, and fixedly the other end of water pipe 12 is delivery port 10.
Described fixedly water pipe 12 is socketed to form by interior pipe 16 and outer tube 14, is provided with gap 15 between interior pipe 16 and the outer tube 14.Gap 15 can be avoided flowing out fixedly, and the high-temperature water of water pipe 12 makes cooling water heat up energy savings.
