Abstract
The invention provides a high-temperature hanging embedded scraper transporter. On one hand, the safety factor of a single-row chain is increased from 8 to16 by connecting a single-row chain rod witha pin shaft; on the other hand, a scraper with the thickness of 16mm is adopted and obliquely welded on the chain rod at an angle of 75 degrees, thereby avoiding a floating chain phenomenon occurringin the transportation process. A tension riding wheel is additionally arranged at the back upper place of a head wheel, a scraper chain sags under the influence of self weight in the running process,a tension adjusting device is arranged on a tail wheel, and the tension riding wheel and the tension adjusting device coact to compensate the extension of the scraper chain, so as to prevent the occurrence of chain jamming. A retainer ring at one end of the pin shaft is fixed in a spot welding mode, thereby avoiding chain shedding caused by the shedding of the retainer ring in a high temperature state. The high-temperature hanging embedded scraper transporter can perform the transportation operation at high temperature, is simultaneously suitable for transporting the flue dust and slag of converter waste heat boilers of non-ferrous metal smelting works including copper, zinc, aluminum, nickel and the like, and is an ideal product for substituting for imported products.
Description
Technical field
The present invention relates to a kind of scraping plate conveying device that buries, particularly a kind of high-temperature hanging embedded scraper transporter.
Background technology
The eighties in 20th century, the fast development of China YouSe metal smelt provides opportunity for introduction high temperature buries the scraper plate machine, the external at present high temperature of introducing buries the scraper plate load transfer device in operational process, has following problem, mainly shows as under hot conditions, member such as movement parts and housing is easy to oxidation, cause strength degradation, flight chain extends thereupon, produces stretched wire, cause the great wheel chain jamming, can't normal operation; Flight chain bonded assembly bearing pin is loosening, causes and takes off chain, at high temperature is difficult to maintenance.And because of overseas equipment is in monopoly position, equipment price is high.
Summary of the invention
Technical matters to be solved by this invention provides a kind of high-temperature hanging embedded scraper transporter, can bear the transportation work of high-temperature residual heat boiler smelting smoke dust or slag.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of high-temperature hanging embedded scraper transporter, comprise housing, tail wheel and great wheel are installed in the housing, primary mover is connected with great wheel by transmission device, tail wheel is connected by flight chain with great wheel, and the tail wheel place is provided with the tension control apparatus, and the great wheel back upper place is provided with the tensioning support roller.
Flight chain is formed by connecting by a plurality of chain bars and bearing pin, and the back-up ring of bearing pin one end is fixing by welding, and scraper plate and chain bar are welded to connect.
Angle is the 60-80 degree between scraper plate and the chain bar.
The material of chain bar and bearing pin is 20CrMnTi, and carburizing and quenching hardness is 45-50HRC, and the scraper plate material is 20g.
The thickness of scraper plate is 12-18mm.
Shell material is 20g.
The housing top is provided with inlet point, is provided with circular connecting bore near housing mounting center line position, and both sides are provided with waist shape connecting bore.
A kind of high-temperature hanging embedded scraper transporter provided by the invention is connected with bearing pin by adopting one-rank chain bar, and selects high strength chain bar for use, makes single chain safety factor bring up to 16 from 8; The material of chain bar and bearing pin is 20CrMnTi, and carries out carburizing and Quenching Treatment, and hardness reaches HRC45 ~ 50.Existing good resistance to abrasion and bending strength have good comprehensive mechanical performance again behind the cementation process.Wear-resistant, intensity is high, long service life.The scraper plate material is 20g, and on the one hand, the intensity and the toughness of this material are better, and enough intensity is being arranged below 550 ℃, and antioxidant, this intensity guarantee that scraper plate is at high temperature indeformable; On the other hand, the welding performance that it is good guarantees that the welding of scraper plate and chain bar does not at high temperature come off.Reach 2t/m at flue dust proportion
3Working environment under, adopt the heavy chain bar of single-unit quality 4kg on the one hand, adopt thickness to reach the 16mm scraper plate on the other hand, and 75 degree that tilt are welded on the chain bar, thereby produce floating chain phenomenon in the process of having avoided carrying, above scheme can reduce flight chain elongation at high temperature as far as possible.
Simultaneously be furnished with a tensioning support roller in addition in the back upper place of great wheel, flight chain is influenced by deadweight in operational process and sagging, thereby can the elongation of automatic compensation chain when high temperature.Go out to be provided with the tension control apparatus at tail wheel, mechanism strains flight chain by the spring spiro rod formula, and tensioning support roller and the combined action of tension control apparatus prevent the generation of chain jamming with the elongation of compensation flight chain.
The back-up ring of bearing pin one end is fixed by the spot welding mode, thereby has avoided coming off and causing and take off chain at condition of high temperature back-up ring.
Case material is 20g, adopts thicker steel plate, is that object has bigger rigidity.Trough width in the housing and highly bigger, and running velocity is 0.03 ~ 0.06m/s only, thus be beneficial to the heat radiation of material.The reduction of temperature of charge also can reduce the elongation of flight chain.
Because the length of inlet point is near the entire length of equipment, the scheme that inlet point and the connection mode of heat boiler outlet have adopted near the circular connecting bore the line of centers to combine with the waist shape connecting bore of both sides, this measure can be avoided the influence of phenomenon to equipment operation of expanding with heat and contract with cold of boiler discharging opening.
The present invention is rational in infrastructure, and material is selected for use suitable, can bear the transportation work under the high temperature, is the ideal product that substitutes import.
