Description
Technical Field
The utility model relates to a slag dragging machine, in particular to a gasification furnace slag dragging machine.
Background
The slag extractor of the gasification furnace is a mechanical slag extractor for the gasification boiler. The existing gasification furnace slag scooping machine is a scraper slag scooping device, and continuously conveys cold quenching slag immersed in water to a slag outlet through a continuously running scraper chain, so that the slag removal process is completed. When the existing scraper type slag dragging machine operates, the scraper rubs on the bottom plate. The slag pool is provided with a large amount of slag and slag water with stronger corrosiveness to corrode the scraping plate, so that the abrasion of the scraping plate is accelerated. The existing scraper slag dragging machine of the gasification furnace is divided into a horizontal section and an inclined section, and the arrangement form occupies large space.
Disclosure of Invention
The utility model aims to solve the technical problems of providing a gasification furnace slag dragging machine, which is improved on the basis of the existing gasification furnace scraper slag dragging machine, prolongs the service life of equipment and improves the service performance of the equipment.
In order to solve the technical problems, the utility model adopts the following technical scheme:
the gasification furnace slag dragging machine comprises a frame, wherein the frame is obliquely upwards arranged; the chain bucket group is wound on the head wheel group and the tail wheel group and is driven by a driving motor at the upper end of the frame;
the chain bucket group comprises a hopper, a water passing hole is fixed on the hopper, the left and right sides of the hopper are connected with a chain, and the chain is a roller chain.
The driving motor is arranged on the sliding bearing seat, and the left sliding bearing seat and the right sliding bearing seat are adjusted to move back and forth through the screw rod tensioning mechanism.
The interval between the adjacent hoppers is 4 chain pitches.
The gasification furnace slag dragging machine has the following technical effects:
1) The design of a frame, a chain bucket group and the like is adopted, the previous scraper conveying is changed into hopper conveying, and the chain adopts a roller chain with large rollers, so that rolling friction is realized, abrasion is reduced, and the service life of equipment is prolonged.
2) The device can be obliquely arranged, has a larger angle and can reduce occupied space; other angular arrangements or vertical arrangements are also possible in this application, with flexibility.
3) The mode that a connecting plate is welded on the chain plate of the chain to be connected with the hopper or the scraper is changed into the mode that the chain plate of the roller chain is directly connected with the hopper, so that the working procedure is saved, and the integral connection is reliable.
4) The hopper is uniformly perforated, so that drainage is facilitated when the hopper is fished out; meanwhile, the interval between the hoppers is 4 traction chain pitches, and proper intervals are also beneficial to drainage.
Drawings
The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:
fig. 1 is a schematic structural view of the present utility model.
Fig. 2 is a schematic view of a partial structure of a head part in the present utility model.
FIG. 3 is a schematic view of a chain bucket group according to the present utility model.
Fig. 4 is a schematic view of the installation of the present utility model.
In the figure: the device comprises a frame 1, a head pulley group 2, a tail pulley group 3, a chain bucket group 4, a driving motor 5 and a tensioning device 6.
Detailed Description
As shown in fig. 1, the gasification furnace slag conveyor comprises a frame 1, wherein the frame 1 is obliquely upwards arranged, the lower end of the frame 1 is arranged in a slag quenching tank, and the upper end of the frame is arranged beside the slag quenching tank. The frame 1 has a large inclination angle and occupies a small space. The upper end and the lower end of the frame 1 are correspondingly provided with a head pulley group 2 and a tail pulley group 3, the head pulley group 2 and the tail pulley group 3 are wound with a chain bucket group 4, and the chain bucket group 4 is driven by a driving motor 5 at the upper end of the frame 1. The chain bucket group 4 comprises a hopper 4.1 and a chain 4.3, wherein a water passing hole 4.2 is fixed on the hopper 4.1, the hopper adopts a punching design, the water drainage is faster, and the water content is less after the fishing. The chain plates at every fourth chain link of the chain 4.3 are special-shaped chain plates, one end of each special-shaped chain plate is used as a chain plate of the chain 4.3 to be arranged on the chain 4.3, and the other end is used as a connecting part to be connected with the hopper 4.1 to form a whole. The chain 4.3 is the roller chain, for the scraper blade and the sliding friction of bottom plate of current gasifier dragveyer, the roller in the chain 4.3 in this application is big gyro wheel, and big gyro wheel contacts with the guide rail on the frame 1, makes the main friction of this equipment be the rolling friction of roller chain and guide rail, and the wearing and tearing are littleer, effectively lengthen the change cycle.
The driving motor 5 is arranged on the sliding bearing seat 7, and the left sliding bearing seat 7 and the right sliding bearing seat 7 are adjusted to move back and forth through the screw rod tensioning mechanism 6. The driving motor 5 is directly connected with the head pulley group 2, and when the chain bucket group tensioning is adjusted each time, the driving motor 5 moves along with the driving shaft, and compared with other driving arrangement modes (chain transmission, belt transmission and the like), the tensioning step of the adjusting transmission device is omitted, and the tensioning adjustment process is greatly facilitated.
The interval between the adjacent hoppers 4.1 is 4 chains 4.3 pitch, and the interval is proper, so that the water discharge is facilitated.
Working principle and process: the device is a chain bucket type slag conveyor, a driving motor 5 drives a head pulley group 2 to rotate, the head pulley group 2 drives a chain bucket group 4 to continuously and circularly move, the chain bucket group 4 takes water quenching slag at a tail pulley group 3 at the lower end of a frame 1, and the chain bucket group 4 continuously and circularly moves to the upper end of the frame with the water quenching slag. In the upward movement process of the chain bucket group 4, water flows back into the slag pool from the small holes of the hopper, so that the water filtering effect is achieved. The chain bucket group 4 bypasses the head wheel group 2 after running to the upper end of the frame 1, the hopper gradually turns from the opening upwards to the opening downwards, the water quenching slag in the hopper is poured out by gravity and centrifugal force, and the water quenching slag is collected below the head wheel group 2.
