Description

Low fault rate and slagging-off speed reliable and stable dross removal mechanism

Technical Field

The invention belongs to the field of slag removers of garbage incinerators, and particularly relates to a slag removing device for a garbage incinerator, which has low failure rate and stable and reliable slag removing speed.

Background

The slag remover (also called slag extractor) for the garbage incinerator is generally a chain plate type slag remover, the feeding end of the slag remover is arranged below the discharging port of the garbage incinerator, and the slag remover transfers waste slag discharged by the garbage incinerator to another place. The structure of slagging-off machine includes the frame, is equipped with the chute feeder in the frame, is equipped with power unit in the frame, is equipped with the chain of being connected with power unit in the chute feeder, and the chain rotates under power unit's effect, is equipped with a plurality of link joints on the chain, and the both ends of link joint are close the width of chute feeder about chain symmetric distribution, the length of link joint, and the chain rotates and drives the link joint and rotate, and the link joint will drop into the waste residue of chute feeder and hang from the feed end and send the discharge end.

It is found in the use, because waste incinerator's fuel composition is complicated, the waste residue composition that obtains is complicated, some waste residues have high viscidity, some waste residues have high hardness, the waste residue of high hardness mixes with high viscidity waste residue, the adhesion is on the lateral wall about the chute feeder, lead to the both ends atress of link joint, the both ends atress of link joint is difficult to reach the balance, the link joint takes place the slope thereupon, leave the space between the lateral wall of link joint and chute feeder, the waste residue that is located the chute feeder both sides is difficult to be scraped, the slagging-off speed of slagging-off machine reduces, the slagging-off speed of slagging-off machine is unstable. In addition, influenced by waste incinerator's fuel composition, some waste residues are bulky when hardness is higher, when entering into the space between link joint and the feed chute, probably blocked the link joint, the link joint needs very big power just can break the waste residue by extrusion, resumes the operation again, when the link joint breaks the waste residue by extrusion, the chain is easily elongated or breaks, power unit's motor burns out easily, leads to the fault rate of slagging-off machine higher.

Therefore, the existing slag remover has the defects of unstable slag removing speed and higher failure rate.

Disclosure of Invention

The invention aims to provide a deslagging device with low failure rate and stable and reliable deslagging speed. The invention has the advantages of stable deslagging speed and low failure rate.

The technical scheme of the invention is as follows: the utility model provides a low fault rate and slagging-off speed reliable and stable dross removal mechanism, includes the frame, is equipped with the chute feeder in the frame, is equipped with power unit in the frame, is equipped with the chain of being connected with power unit in the chute feeder, and the chain is the annular, is equipped with a plurality of link joint, its characterized in that on the chain: racks parallel to the chain are arranged on two opposite side walls of the feeding groove, connecting rods are arranged at two ends of each chain plate, gears meshed with the corresponding racks are arranged at the end parts of the connecting rods, and the gears are connected with the connecting rods through one-way bearings; the chain plate is bent, the bending direction of the chain plate faces to the rotating direction of the chain, and the bending angle of the chain plate is 30-50 degrees.

In the slag removing device with low failure rate and stable and reliable slag removing speed, the chain plate is bent, and the bending direction of the chain plate faces to the rotating direction of the chain.

In the deslagging device with low failure rate and stable and reliable deslagging speed, the rack and the gear are meshed and rotated in a matching way through the helical teeth, and the tilting direction of the helical teeth is the same as the bending direction of the adjacent chain plate.

Among the aforesaid low fault rate and the reliable and stable dross removal mechanism of slagging-off speed, the discharge end of chute feeder is equipped with the cylinder, and the both ends of cylinder all are equipped with to rotate with the frame and are connected, and one end of cylinder is equipped with and is equipped with the second motor fixed with the frame, and the steel wire is densely covered on the cylinder.

Compared with the prior art, the invention is improved on the basis of the existing slag remover as follows, firstly, gears rotating in one direction are arranged at two ends of a chain plate, and racks matched with the gears are arranged on a rack, so that the two ends of the chain plate keep advancing synchronously, the chain plate cannot incline, no gap is left between the chain plate and the side wall of a feeding groove, waste residues at two sides of the feeding groove can be guaranteed to be scraped by the chain plate, the slag removing speed of the slag remover cannot be reduced, and the slag removing speed of the slag remover is stable. Because the space can not be left between the lateral wall of link joint and chute feeder, the higher and great waste residue of hardness also can not enter into between link joint and the chute feeder, is difficult for blocking the link joint, and the chain is difficult for being elongated, power unit's motor is difficult for burning out to the fault rate of slagging-off machine is low. The second, set up one on the link joint and bent for receive the decurrent reaction force in the time of the link joint scraping the lime-ash, under reaction force, the lower extreme of link joint and the inseparabler laminating of the bottom surface of chute feeder, thereby guarantee that the lime-ash strikes off cleaner, also help keeping the slagging-off speed of slagging-off machine stable. And the link joint is through bending back, and the link joint can increase in the whole thickness of pay-off direction, also can make the link joint be difficult for taking place to rotate, is difficult for taking place to incline promptly, guarantees that the slagging-off speed of slagging-off machine is stable. Thirdly, the distance between the chain plate and the gear is increased by utilizing the connecting rod, so that ash in the feeding groove is prevented from contacting the gear rack; the roller is used for driving the steel wire to rotate, so that residual ash on the chain plate is further removed, and the ash is prevented from being driven to fall onto the gear rack when the chain plate moves reversely on the upper side; ensure that the meshing between the gear and the rack is smooth and easy, reduce the fault rate of the slag remover. And fourthly, the gear is connected with the rack through helical teeth, so that the gear cannot float up and down on the rack, the chain plate is prevented from being lifted up under the reaction force of waste residues, a gap is reserved between the chain plate and the bottom surface of the feeding groove, and the slag removal speed of the slag remover is also guaranteed to be stable. Therefore, the invention has the advantages of stable deslagging speed and low failure rate.
