Description

Technical Field

[0001] The utility model relates to the technical field of mechanical engineering, and particularly relates to an auxiliary repair device for repairing the scraper of a slag discharging machine. Background Art

[0002] The slag discharging machine is a commonly used discharging device in the solid dangerous waste incineration treatment industry. At present, the discharging methods of solid dangerous waste incineration systems at home and abroad all adopt the form of a slag discharging machine to collect and scrape the solid dangerous waste burned by the rotary kiln.

[0003] The operation of the incineration system is continuous throughout the day, and the slag falling at the tail of the rotary kiln always exists. Therefore, the transmission scraper part of the slag discharging machine also operates for a long time. The hanging ear of the scraper of the slag discharging machine contacts the bottom cast stone slab during operation. Therefore, the hanging ear of the scraper of the slag discharging machine will gradually wear due to long-term friction. When the wear is serious, a notch will appear in the pin hole of the hanging ear, posing a potential hazard. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the technical solution adopted by the utility model to solve its technical problems is: an auxiliary repair device for repairing the scraper of a slag discharging machine, including: a slag discharging machine body; a chain, the outer wall of the chain is rotationally connected to the inner wall of the slag discharging machine body through a motor; a repair component, the bottom of the repair component is fixedly connected to the inner wall of the slag discharging machine body; a slag receiving tank, the slag receiving tank is arranged outside the slag discharging machine body; a repair component, the bottom of the repair component is fixedly connected to the inner wall of the slag discharging machine body; the repair component includes a base, the base is processed and manufactured by using an H-shaped steel, and the flange of the H-shaped steel is used as the bottom positioning surface. Since the contact surface between the flange and the ground can be regarded as two lines, it can better avoid the influence caused by uneven ground or shaking of the working surface, and the relatively large web plate is used as the working surface for repairing the scraper body. Two positioning baffles are fixedly connected to both sides of the top of the base. The positioning baffles are welded to the base, and the inner spacing of the baffles is set according to the scraper installation dimensions. In this way, the welded scraper body and the new hanging ear will not exceed or be smaller than the required installation dimensions after welding, ensuring the smooth installation of the repaired scraper body. A positioning pin is threadedly connected to the inner wall of the positioning baffle, and an auxiliary positioning block is rotationally connected to the outer wall of the positioning pin. The outer wall of the chain is fixedly connected with a scraper body, and the scraper bodies are linearly arranged along the outer wall of the chain.

[0005] Preferably, the bottom of the auxiliary positioning block is slidably connected to the top of the base, and the bottom of the base is fixedly connected to the inner wall of the slag discharge machine body. The auxiliary positioning block is welded to the base. Two platforms are designed on the inner side of the positioning block. The lower platform is used to position the narrow scraper in the horizontal and vertical directions, and the higher platform is used to position the wide scraper in the horizontal and vertical directions. At this time, the positioning of the lugs and the scraper body to be welded has been completed, and then butt welding can be carried out to complete the repair work of the scraper body. The outer walls on both sides of the scraper body are fixedly connected with lugs, and the lugs are linearly arranged along the outer wall of the chain.

[0006] Preferably, the outer wall of the lug is slidably connected to the inner wall of the auxiliary positioning block through a wide scraper groove, and the wide scraper groove is opened in the wall of the auxiliary positioning block. A narrow scraper groove is opened in the wall of the auxiliary positioning block. The outer wall of the auxiliary positioning block is in contact with the outer wall of the positioning baffle, and there is a height difference between the narrow scraper groove and the wide scraper groove.

[0007] The beneficial effects of the present utility model are as follows:

[0008] 1. By setting the repair component, during the working process, the present utility model optimizes and reforms the situation where the relative positions of each previous scraper and the lug need to be manually measured during welding. Only by placing the lug and the scraper body to be welded on the auxiliary positioning block respectively can the relative positions of the two be determined, and it can ensure the influence caused by slight welding deformation during the welding process, improving the work efficiency.

[0009] 2. By setting the repair component, the scraper will be bent by the waste falling from the tail of the rotary kiln, but mainly during the transmission with the chain, the lugs on both sides of the scraper body rub against the bottom cast stone slab, causing wear. Therefore, when repairing the scraper body, in addition to correcting the bent scraper body, mainly cutting off the worn lugs on the scraper body removed and welding new lugs, reducing the spare part cost and achieving the purpose of repairing and reusing waste.

[0019] Embodiment:

[0020] Please refer to Figure 1 - Figure 8 , the present utility model provides a technical solution: an auxiliary repair device for repairing the scraper of a slag discharge machine, including: a slag discharge machine body 1; a chain 2, the outer wall of the chain 2 is rotationally connected to the inner wall of the slag discharge machine body 1 through a motor; a repair component 5, the bottom of the repair component 5 is fixedly connected to the inner wall of the slag discharge machine body 1; a slag receiving trough 3, the slag receiving trough 3 is arranged outside the slag discharge machine body 1; a repair component 5, the bottom of the repair component 5 is fixedly connected to the inner wall of the slag discharge machine body 1; the repair component 5 includes a base 51, both sides of the top of the base 51 are fixedly connected with positioning baffles 55, the inner wall of the positioning baffle 55 is threadedly connected with a positioning pin 54, the outer wall of the positioning pin 54 is rotationally connected with an auxiliary positioning block 52, the outer wall of the chain 2 is fixedly connected with a scraper body 4, and the scraper body 4 is linearly arranged along the outer wall of the chain 2. The base 51 is processed and manufactured using existing H-shaped steel, and the base 51 is supported by two rib plates below. When placed horizontally, it can compensate for the error caused by uneven ground, so that the wide scraper and the narrow scraper to be repaired can operate in a relatively independent and horizontal environment.

[0021] The bottom of the auxiliary positioning block 52 is slidably connected to the top of the base 51, the bottom of the base 51 is fixedly connected to the inner wall of the slag discharge machine body 1, and hanging ears 53 are fixedly connected to the outer walls on both sides of the scraper body 4, and the hanging ears 53 are linearly arranged along the outer wall of the chain 2. The auxiliary positioning block 52 can position the wide scraper and the narrow scraper in both the horizontal direction and the height direction, so that they are positioned in both the horizontal direction and the height direction at the same time, improving the efficiency and the dimensional accuracy.

[0022] The outer wall of the hanging ear 53 is slidably connected to the inner wall of the auxiliary positioning block 52 through the wide scraper groove 57, and the wide scraper groove 57 is opened in the wall of the auxiliary positioning block 52. A narrow scraper groove 58 is opened in the wall of the auxiliary positioning block 52. The outer wall of the auxiliary positioning block 52 is in contact with the outer wall of the positioning baffle 55. The positioning baffle 55 can accurately position and fix the hanging ear 53 of the scraper body 4 to be welded to prevent deformation or displacement during welding and affect the overall dimensional accuracy.

[0023] Working principle:

[0024] During use, the power component in the slag discharge machine body 1 drives the chain 2 to rotate, so that the chain 2 drives the scraper body 4 to move in the slag discharge machine body 1, so as to drive the slag in the slag discharge machine to move to the slag receiving groove 3 outside the slag discharge machine body 1. When the scraper body 4 needs to be repaired, only the repair component 5 at the bottom of the slag discharge machine body 1 can be used to facilitate the repair of the scraper body 4.

[0025] When using the repair component 5, only need to drive the hanging ear 53 on the scraper body 4 to move to the auxiliary positioning block 52 through the chain 2. Then, by rotating the positioning pin 54 on the positioning baffle 55, the positioning pin 54 synchronously presses the auxiliary positioning block 52 during the rotation process, so that the hanging ear 53 on the scraper is in the groove on the auxiliary positioning block 52. Two groups of grooves are opened on the auxiliary positioning block 52, corresponding to different scraper bodies 4 respectively. When repairing the wide scraper, only need to slide the hanging ear 53 on the wide scraper into the wide scraper groove 57, and for the narrow scraper, only need to slide the hanging ear 53 on the narrow scraper into the narrow scraper groove 58.

[0026] The hanging ear 53 on the scraper body 4 is positioned by the groove on the auxiliary positioning block 52 on the base 51, so that after cutting off the old hanging ear 53, the positioning time for the new hanging ear 53 is reduced.

[0027] Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments.
