Detailed Description

For the purpose of facilitating understanding, the present invention will be further described with reference to the accompanying drawings.

Referring to fig. 1, the slag extractor for a garbage incinerator according to the embodiment of the present invention includes a housing 1, a traction chain, and a driving device for driving the traction chain, wherein a plurality of objects to be dragged 3 are mounted on the traction chain, a cross section of the objects to be dragged 3 is as shown in fig. 2, a cross sectional profile includes four arc line segments connected end to end, and the arc line segments are concave to a center line of the objects to be dragged 3. The top of the shell 1 is provided with an inlet communicated with a final-stage grate slag discharge port of the garbage incinerator, a bottom plate of the shell 1 is an arc-shaped plate with a convex middle part, the head and the tail of the shell 1 are both provided with an opening, and a traction chain penetrates through the opening and surrounds the bottom plate of the shell 1.

In this embodiment, the driving device for the dragging chain comprises a motor 2 arranged at the tail of a housing 1, the motor 2 drives the dragging chain through a gear transmission mechanism, the dragging chain circularly rotates around a bottom plate of the housing 1, a dragged body 3 moving along with the dragging chain enters from an opening at the head of the housing 1, slag in the housing 1 is scraped to the opening at the tail, when the dragged body 3 comes out from the opening at the tail, the slag falls into a slag pit at the back of a slag extractor, and the dragged body 3 returns to the opening at the head through the lower part of the housing 1, and the process is repeated.

As can be seen from fig. 1, the slag discharging machine provided by the utility model discharges slag through the plurality of dragged bodies 3, the damage of the individual dragged body 3 does not affect the normal operation of the equipment, and meanwhile, the dragged body 3 enters the outer side of the shell 1 along with the motion track, so that the damaged dragged body 3 can be conveniently replaced.

In order to enable the dragged body 3 to be better shoveled into a slag pile in the shell 1 to form a larger slag scraping amount, the dragged body 3 is rotatably connected with the dragging chain in the embodiment, so that the dragged body 3 can automatically adjust the posture, and a more effective slag scraping is formed. In a specific practical application, the cross-sectional profile of the towed body 3 can also be three or five arc line segments which are connected end to end.

In order to clean the slag remained on the body 3 in time, the present embodiment installs the shifter 5 on the outer surface of the bottom plate of the housing 1, and the shifter 5 contacts with the body 3 passing by, thereby shaking off the remained slag. In this embodiment, the number of the actuators 5 is two, one of which is located at the lowest point of the bottom plate of the housing 1 and is used for contacting the towed body 3 of the horizontal movement section, and the other of which is located at the front end of the head of the housing 1 and is used for contacting the towed body 3 of the ascending movement section.

As shown in fig. 3, the puller 5 may be designed in the shape of a rake comprising a plurality of rake teeth arranged in the direction of the centre line of the body 3 to be pulled. In order to reduce the wear on the body 3 to be dragged, the rake teeth of the puller 5 can be made of rubber bars. As shown in fig. 1, the present embodiment is provided with a collecting plate 7 below the traction chain, and one end of the collecting plate 7 near the slag pit is arranged to be inclined downward, so that the shaken-off slag can slide into the slag pit along the collecting plate 7.

In order to further clean the residual slag on the towed body 3, the embodiment is provided with the water supply cleaner 4 at the opening of the head part of the shell 1, and the water supply cleaner 4 supplies water (for cooling the slag) into the shell 1 and cleans the towed body 3 running to the opening of the head part, thereby achieving the purpose of one water for two purposes and reducing the arrangement of pipelines.

In order to reduce the great impact of the falling slag on the towed body 3 and the bottom plate of the shell 1, the buffer baffle 6 is arranged at the inlet of the top of the shell 1, and the buffer baffle 6 is an arc-shaped plate with an upward middle part. In order to enhance the buffering effect, the present embodiment employs two buffering baffles 6, and the baffles are arranged one above the other on two opposite inner walls of the inlet, as shown in fig. 1.
