Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of slag collecting hopper, especially relates to a slag collecting hopper for electric furnace smelting. BACKGROUND

[0002] The slag collecting hopper for electric furnace smelting is a device for collecting and storing slag in the electric furnace smelting process. In the electric furnace smelting process, the metal raw materials are melted at high temperature, and impurities and oxides in the metal liquid will float on the surface of the metal liquid to form slag. The slag collecting hopper is placed near the slag outlet of the electric furnace, and the slag flows into the slag collecting hopper through the slag outlet. When the slag collecting hopper is full or reaches a certain amount of slag, the slag collecting hopper is lifted and transported to the designated slag treatment area by a travelling crane for subsequent treatment, thereby achieving the functions of collecting slag, improving safety, and facilitating subsequent treatment of the slag.

[0003] According to the search, the patent with the application number 2011204881728.2 discloses a slag collecting hopper for electric furnace smelting. The patent is more suitable for lifting and transporting by a travelling crane in a workshop and facilitates slag pouring operation by setting an inclined surface on the front part of the rectangular slag collecting hopper and setting symmetrical lifting holes on the front and rear ends of the two sides of the slag collecting hopper. However, in actual use, due to the high temperature of part of the slag, the slag will adhere to the inner wall of the slag collecting hopper. Over time, it is difficult to clean these slags, resulting in incomplete slag pouring. CONTENT OF THE UTILITY MODEL

[0004] To solve the problems in the prior art, the utility model provides a slag collecting hopper for electric furnace smelting. By setting a semicircular slag collecting hopper body, the slag in the slag collecting hopper body can be scraped off each time by cooperating with the scraping mechanism, avoiding the adhesion of part of the slag to the inner wall of the slag collecting hopper body, avoiding the subsequent manual cleaning trouble, and ensuring more complete slag pouring.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0006] A slag collecting hopper for electric furnace smelting includes a slag collecting hopper body and a scraping mechanism. Two front and rear symmetrical lifting lugs are fixed on the left and right ends of the upper side of the slag collecting hopper body, and lifting holes are formed in the lifting lugs. The slag collecting hopper body is in a semicircular structure. The scraping mechanism includes an ear plate, a rotating shaft, a servo motor, a connecting rod, and a scraper. The ear plate is fixed on the upper middle part of the slag collecting hopper body. The rotating shaft is rotatably connected between the ear plates. The servo motor is installed on the front side of the ear plate at the front end and connected with the rotating shaft. The scraper is connected with the rotating shaft through the connecting rods on the left side of the rotating shaft. The connecting rods are equidistantly arranged along the side surface of the rotating shaft. The outer side of the scraper is slidably connected with the inner wall of the slag collecting hopper body. By setting the semicircular slag collecting hopper body and cooperating with the scraping mechanism, the slag in the slag collecting hopper body can be scraped off each time, avoiding the adhesion of part of the slag to the inner wall of the slag collecting hopper body, avoiding the subsequent manual cleaning trouble, and ensuring more complete slag pouring.

[0007] Further, the rotating shaft and the slag collecting bucket body are coaxially arranged, so that the scraper can reach each part of the inner wall of the slag collecting bucket body.

[0008] Further, the connecting rod and the scraper are cast steel parts, which can ensure normal use in a high temperature environment and have a long service life.

[0009] Compared with the prior art, the beneficial effects of the utility model are that: through the setting of the semicircular slag collecting bucket body, the slag in the slag collecting bucket body can be scraped off during each time of pouring, so that the slag adhering to the inner wall of the slag collecting bucket body is avoided, the subsequent manual cleaning is avoided, the pouring of the slag is ensured to be more thorough, the rotating shaft and the slag collecting bucket body are coaxially arranged, so that the scraper can reach each part of the inner wall of the slag collecting bucket body, and the connecting rod and the scraper are cast steel parts, which can ensure normal use in a high temperature environment and have a long service life.
