Abstract

The utility model relates to a dust ash conveyer which is characterized in that a scratch bar of a circular pushing component, which is composed of a flexible cable of a steel wire of the conveyer is fixed with the flexible cable of the steel wire by point contact. The flexible cable of the steel wire is a smooth circular arc by passing through a chain wheel. The utility model overcomes the defect that the steel cable of the present used conveyer is equispaced when passing through the chain wheel, the flexible cable of the steel wire can not be damaged, and the flexible cable of the steel wire can not broken. Oblique plates of about 30 DEG are arranged among the head of the conveyer, an end closing plate and a soleplate, and the oblique plate effectively overcomes the defect that material are easy to pile at the head and the end of the passed conveyer. The working stability and service life of the dust ash conveyer are enhanced.

Description

A kind of dust conveyer

The utility model relates to a kind of feedway, particularly a kind of dust conveyer.

The dust conveyer is industry requisite devices when convey materials such as coal-burning power plant, cement, chemical industry.Present employed dust conveyer such as embedded scraper transporter, conveyer etc., owing to the reason in the design, exist many deficiencies, chain is relative friction with cabinet during the embedded scraper transporter motion, so wearing and tearing are big, the maintenance rate height, the present conveyer that uses, owing to have problems on the Fixed Design of scraping teeth and steel rope, making steel rope is not level and smooth circular arc by sprocket wheel the time, but equally spaced polygon, so steel rope is easy to fracture, its head and afterbody casing are that 90 degree are square in addition, make solid accumulation two easily, cause and climb chain, thereby influence the normal use of conveyer.

The purpose of this utility model provides a kind of novel dust conveyer, this dust conveyer scraper contacts fixing with the gentle rope point of steel wire, the gentle rope of steel wire is level and smooth circular arc during by sprocket wheel, can not cause that the gentle rope of steel wire fractures, and can overcome solid accumulation and cause the fault of climbing chain, thereby improve greatly the service life of conveyer.

The purpose of this utility model realizes by following proposal: this dust conveyer is equipped with two pushing pieces of striding the gentle Suo Zucheng of steel wire of 60mm mutually in seal casing, the pushing piece of the gentle Suo Zucheng of this steel wire is driven by two sprocket wheels at a distance of certain distance, the clevis bolt that scraper is made with round steel is fixed on the gentle rope of steel wire by certain size, because it is that a contact is fixing that clevis bolt is fixed on scraper on the gentle rope of steel wire, so when the gentle rope of steel wire is level and smooth circular arc during by sprocket wheel, rather than present equally spaced polygon at the conveyer that uses, thereby can not damage the gentle rope of steel wire, the service life of having improved conveyer.Doing the swash plate that has about 30 degree between the head of conveyer and afterbody shrouding and the base plate, this swash plate can actv. overcomes conveyer is in the past piled up material easily at head and tail defective, overcome because of solid accumulation causes and climbed chain, and then the deficiency of damage steel rope, the working stability and the service life of having improved conveyer.

A kind of dust conveyer of the utility model is compared with existing conveyer, has modern design, rational in infrastructure, uses and stablizes, and the gentle rope of steel wire is frangibility not, long service life, the advantage that maintenance cost is low.

Below in conjunction with accompanying drawing the utility model embodiment is described in further detail:

Fig. 1 is the utility model constructional drawing.Fig. 2 is the scraper constructional drawing.Fig. 3 is clevis bolt and scraper assembly drawing.Fig. 4 is the utility model sprocket wheel 45 degree erection plan.Fig. 5 is the central shaft hole sealed picture.

Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, a kind of dust conveyer of the utility model, comprise casing (1), article two, the gentle rope (2) of ring like steel wire, be installed in impeller (3) on the steel wire gentle (2) by certain size, drive the two group sprocket wheels (4) of pushing piece (3) at a distance of certain distance, two reductors (5) as the power of sprocket wheel (4), do the groove that is meshed with pushing piece (3) on the sprocket wheel (4), can both turn round for ease of the positive and negative both direction of sprocket wheel (4), this groove is done in echelon, and the pushing piece that is meshed with it (3) is also done in echelon.When reductor (5) is opened, sprocket wheel (4) rotates, driving the gentle rope (2) of steel wire rotates, and driving pushing piece (3) motion, dust is subjected to the thrust of pushing piece (3), has formed the motion of continous-stable, thereby played the effect of carrying dust, for making the steel wire rope (2) that softens unlikely sagging, on casing, done rope support sheave, so that sprocket wheel (4) can normal operation when driving the gentle rope (2) of steel wire in when operation.

Referring to Fig. 2, Fig. 3, for improving the service life of the gentle rope (2) of steel wire, the impeller (3) of the utility model dust conveyer is made by scraper (6) and clevis bolt (7), be processed with two pairs of screws on each scraper (6), clevis bolt (7) is made with the garden steel, each scraper (6) is combined with the screw that two clevis bolts (7) pass on the scraper (6), scraper (6) is all being done recessed radian (9) with gentle rope (2) bearing of two steel wires, this recessed radian (9) just in time forms a garden shape with clevis bolt (7), by tightening the nut of clevis bolt (7), can regulate the size of this circle, after scraper (6) and clevis bolt (7) are clamped the gentle rope (2) of steel wire, tightening nuts, scraper (6) can be fixed on firmly on the gentle rope (2) of steel wire, rope (2) is to contact because clevis bolt (7) and steel wire soften, so when impeller (3) passes through sprocket wheel (4), it is level and smooth garden arc, rather than present polygon in the conveyer that uses, the steel wire rope (2) that softens is rolled over, impaired, can not fracture, thus the service life of having improved conveyer.

Referring to Fig. 4, two sprocket wheels (4) of the utility model dust conveyer are spent on the bearing seat (8) on inclined-planes 45 by bearing installation by axis respectively, and its effect is to lower support height, bear the pulling force increasing thereby make, not yielding, prevented bearing partially, sting fault such as axle.Do the swash plate (13) about 30 degree between head and drive end unit shrouding (12) and the base plate, can make dust by the time stop incessantly can not pile up.

Referring to Fig. 5, for improving the leak tightness of dust conveyer, anti-leak-stopping powder is increased work efficiency, and in the casing center shaft of conveyer head and tail, central shaft hole adopts metallic sheath (14) mechanical seal and packing_seal.

Activity-driven frame (10) has been made in the tail bottom of the utility model dust conveyer, this activity-driven frame (10) is made by four groups of minor axises and roller, join with activity-driven frame (10) two screw-jack (11) are housed, when need are adjusted the degree of tightness of the gentle rope (2) of steel wire, only need pull this screw-jack (11), with regard to adjustable bogie (10), and then the degree of tightness of the gentle rope (2) of adjustment steel wire.

A kind of dust conveyer of the utility model is because the new design of having adopted clevis bolt and scraper to make up, thereby conveyer has been made critical technological improvement, improved the service life and the working stability of conveyer.This dust conveyor construction is reasonable, and reliable in quality has promotion and application prospect widely.
