Abstract

The utility model is a dreg scraping conveyer with relatively lower fault rate and bigger conveying amount in the model of the same power. The invention consists of a conveyor chain, a conveyor chain sprocket and a traction electric motor. The said conveyor chain is provided with the reversing arrangement at the part needing change of direction. The conveyor chain is connected with the scraping plate, and drives the scraping plate through the box body. The said conveyor chain sprocket consists of a head sprocket and a tail sprocket and the tail sprocket is connected with the tensioning device. The invention is characterized in that the conveyor chain is a bushed chain and the bush of the chain contacts with the guide rail inside the box body, and the tooth number of the head sprocket and tail sprocket is odd number.

Description

Scrape the slag conveyer

(1) technical field

The utility model relates to the conveyer field, is specially to scrape the slag conveyer.

(2) background technology

The high-temperature material that power plant, garbage burning factory come out goes out by scraping the slag conveyor delivery after entering cold rinse bank usually.Existing its structure of slag conveyer of scraping is seen Fig. 1, Fig. 2, and it adopts ring-like chain to add scraper plate.Ring-like chain is a gauge member, its model has determined that driving chain sprocket 2 can not be excessive, 1 is motor, chain is walked around driving chain sprocket 2 back on it, distance between the following two halves is less, can't installation tensioner 4, so usually tightening device 4 is installed on the end of conveyer chain, and the end just must be furnished with reverse wheel 3 when tension wheel is installed, have three sprocket wheels together with transportation sprocket 2 at inner end like this, loop chain is walked around three wheels in succession in narrow space, again because ring-like chain all is a forging usually, and the tolerance of forging is bigger, the pitch tolerance of chain has surpassed permissible value, in conveying, very easily occur chain jamming like this, thereby cause affecting the head of chain, the tail wheel operation is inconsistent, and fault rate is higher, sprocket diameter has determined that the space 5 of conveyor pan is narrow, and operational throughput is also few accordingly.

(3) summary of the invention

At existing weak point of scraping the slag conveyer, the utility model provides another to scrape the slag conveyer, and on the type of equal-wattage, fault rate is lower, and operational throughput is bigger.

It is achieved through the following technical solutions: it comprises chain, transportation sprocket, traction electric machine, the position that need commutate at described chain is equipped with reversing arrangement, described chain is connected with scraper plate, and the drive scraper plate passes from casing, described transportation sprocket comprises great wheel and tail wheel, and described tail wheel connects tightening device, and it is characterized in that: described chain is a bushed chain, guide rail in the sleeve of described chain and the casing contacts, and the number of teeth of described great wheel, tail wheel is respectively odd number.

It is further characterized in that: described reversing arrangement comprises sprocket wheel, described sprocket wheel and chain engagement, and described sprocket wheel is installed on described casing; The afterbody of the described casing warpage that makes progress, described tightening device comprises frame, described frame is connected with the tail wheel center shaft, described frame connecting screw rod, the end of described screw rod and described casing warpage section is with being threaded.

The utility model adopts after the said structure, owing to adopt bush chain, the size of transportation sprocket strengthens like this, and then the height of casing is increased, the height of carrying material increases, and under the identical working condition, operational throughput strengthens, and bush chain mostly is blanked part, the precision of blanked part is much larger than the precision of forging, and the pitch tolerance of chain is little, is not prone to chain jamming in the conveying, guarantee to affect the head of chain, the tail wheel operation is consistent, fault rate lowers significantly, and reversing arrangement uses reverse wheel, and the friction between chain and the reverse wheel is rolling friction, friction is less, has further guaranteed fault rate lower in the whole conveyer; And tightening device is positioned at the afterbody of casing, convenient like this adjusting the, the lower fault rate of same further assurance.

(5) specific embodiment

See Fig. 3, Fig. 4, the utility model comprises

chain

10,13, transportation sprocket, traction electric machine 1, at the position that chain need commutate reversing arrangement 3 is installed, reversing arrangement 3 among Fig. 3 has two,

chain

10,13 are connected with scraper plate 9, and drive scraper plate 9 passes from casing 8, scraper plate 9 has a plurality of, concrete quantity is decided according to the length of conveyer, transportation sprocket comprises great wheel 2 and tail wheel 6, and tail wheel 6 connects tightening device 4,

chain

10,13 is bushed chain, guide rail 12 in the sleeve 11 of chain and the casing 8 contact, among Fig. 4 expression be positioned at the guide rail of the latter half.The number of teeth of great wheel 2, tail wheel 6 is respectively odd number.See Fig. 5, reversing arrangement 3 comprises sprocket wheel 15, sprocket wheel 15 and chain engagement, and sprocket wheel 15 is installed on casing 8; The afterbody of casing 8 warpage that makes progress, tightening device 4 comprises frame 14, frame 14 is connected with tail wheel 6 center shafts, frame 14 connecting screw rods 7, the end of screw rod 7 and casing 8 warpage sections is with being threaded.
