Description
Technical Field
The utility model relates to the technical field of disc pelletizers, in particular to a device for removing large pellets in a disc pelletizer.
Background
The disc pelletizer is an important device in the pellet production process and is widely applied to the industrial fields of steel, nonferrous metallurgy, cement, fertilizer and the like.
In the production process, the ball disc obliquely arranged on the disc pelletizer rotates through mechanical transmission, mixed materials and spray water roll into balls in the ball disc, the balls are thrown out to the receiving disc under the action of centrifugal force, the balls fall into a conveying belt from the receiving disc, the qualified balls enter the next working procedure through screening, the unqualified balls return to the mixer and continue to be processed, and the size of the balls can be controlled by adjusting the dip angle. However, the big balls are easy to form due to the influence of multiple factors such as water adding amount and scraper abrasion, and the big balls are always loitered in a ball outlet or long ball area of the ball disc along with the rotary motion of the ball disc, so that the big balls are difficult to be thrown out to a receiving disc along with normal material flow, the growth of the small balls can be influenced to a certain extent, and even the small balls can be broken, thereby influencing the ball production efficiency and the production load, and increasing the energy consumption. Therefore, the big ball in the balling process needs to be cleared in time, so that the generation of the big ball and the long-time stay of the big ball in the disc are avoided as much as possible.
At present, the treatment of large pellets in a disc is generally a manual cleaning method, namely, pellets exceeding the normal diameter are manually raked out by a multi-tooth rake. In the cleaning process, the labor intensity is high, and the rake tool is easy to hook with accessories such as a scraper of the balling disk during operation, so that the rake is free of hands, and a large safety risk exists.
There are also devices installed in the ball pan to break up large pellets, although avoiding the risk of manual breaking, the following problems are present:
most of broken fragments in the disc are in irregular shapes (such as sheets, blocks and the like), and large pellets are easy to form again in the follow-up process, so that the production efficiency of pelletizing is also affected;
crushing in the disc, avoiding crushing some qualified balls, and reducing the pelletizing efficiency;
the crushing mechanism is placed into the pelletizing material for a long time, so that the abrasion is large, and the maintenance cost is high;
the impact of the material condition is larger, and if the material contains more stones and iron blocks, the equipment is easy to damage and the crushing effect is poor.
In view of the above, it would be desirable to provide a device for removing large pellets in a disc pelletizer that at least addresses or alleviates the above-identified deficiencies in the prior art.
Disclosure of Invention

Therefore, the utility model aims to provide a device for removing large pellets in a disc pelletizer, which can solve the technical problems of high labor intensity and safety risk in the manual cleaning process of the large pellets, and can also solve the technical problems of low pelletizing efficiency and the like caused by easily forming the large pellets again by arranging a large pellet crushing device in a pellet tray.
In order to solve the technical problems, the utility model provides a device for removing large pellets in a disc pelletizer, which comprises a fixed frame, a connecting frame, a first telescopic mechanism, a rocker arm, a driving mechanism and a grab bucket, wherein the fixed frame is used for being connected with the disc pelletizer; the grab bucket is provided with a plurality of rake teeth, and the space for passing through the materials with the particle size not larger than the particle size of the qualified pellets is arranged between the rake teeth.
As a further improved technical scheme, the device for removing large pellets in the disc pelletizer provided by the utility model is characterized in that the grab bucket is provided with a grab bucket frame, the middle part of which is hinged with the rocker arm, and a plurality of rake teeth connected with the bottom of the grab bucket frame; and the telescopic rod of the second telescopic mechanism is hinged with the top of the grab bucket frame.
As an optimal technical scheme, the device for removing the large pellets in the disc pelletizer is provided by the utility model, and the driving mechanism is a servo motor.
As an optimal technical scheme, the device for removing the large pellets in the disc pelletizer provided by the utility model comprises the electric push rod, wherein the first end of the electric push rod is hinged with the connecting frame, and the other end of the electric push rod is hinged with the rocker arm.
The foregoing improvements or preferred embodiments may be implemented alone or in combination without conflict.
According to the technical scheme provided by the utility model, the grab bucket is inserted into the material of the balling disk, the big ball is fished out, and the balling disk is moved out. The fished big balls are subjected to sieving and crushing mechanisms of the disc pelletizing system to regenerate pelletizing materials, so that the materials are recycled, and the method is suitable for various material conditions and has no influence on qualified pellets. The technical problems of high labor intensity and high safety risk in the manual large pellet cleaning process are solved, and the technical problems of low pelletizing efficiency, high maintenance cost and the like caused by the fact that the large pellet is easily formed again by arranging the large pellet crushing device in the pellet tray are also avoided.
