Detailed Description
In view of the above, the core of the present invention is to provide a circular roaster to reduce the energy consumption of the bed material.
In order to make the technical field better understand the solution of the present invention, the following detailed description of the present invention is provided with reference to the accompanying drawings and the detailed description.
As shown in fig. 1-6, the utility model discloses a ring type roasting machine, including annular technology section and fan-shaped platform truck 2, wherein, annular technology section is for ball calcination cooling operation district 01, pelletizing district 02 of unloading, pelletizing bed charge district 03 and green ball charge area 04 in proper order, and it still includes the bed charge device of getting certainly, and should get certainly the bed charge device and be used for on the grid plate of fan-shaped platform truck 2 with the pelletizing of pelletizing district 02 of unloading. Through getting the bed charge device certainly in this application with the pelletizing of pelletizing unloading district 02 import to fan-shaped platform truck 2 on the comb board, rather than getting the material from the finished product screening system, consequently, can save the operation link that is used for the operation of bed charge's pelletizing, save technology arrangement space, reduce investment cost.
The specific device for taking and laying the bed charge automatically comprises: the device comprises a revolving frame 1, a crank 4 and a pressing rail 3, wherein the revolving frame 1 is provided with a trolley breast board 10 and a roasting cooling frame 11, a certain amount of green pellets are paved on the roasting cooling frame 11 for roasting and cooling, and the crank 4 is fixedly connected with a mounting shaft 5 of a sector-shaped trolley 2; the above-mentioned pressure rail 3 is used to define the position of the crank 4 and thus the state of the segment trolley 2. Specifically, when the fan-shaped trolley 2 is in the green pellet roasting and cooling operation area 01, the fan-shaped trolley 2 and the revolving frame 1 are on the same horizontal plane and receive green pellets; when the sector trolley 2 is in the pellet unloading area 02, the crank 4 is separated from the limit of the pressing rail 3, and the sector trolley 2 is turned over; when the sector trolley 2 is in the pellet bedding material area 03, the crank 4 is limited by the pressing rail 3, and the sector trolley 2 is in a horizontal state; the width of the fan-shaped trolley 2 is smaller than that of the annular process section.
When the ring type roasting machine works, the revolving frame 1 rotates around the center line of the ring, the pressing rail 3 is fixed on the ground through the fixed support 6, the crank 4 and the fan-shaped trolley 2 form a whole through the mounting shaft 5, when the green pellet roasting cooling working area 01 is formed, the fan-shaped trolley 2 and the revolving frame 1 are on the same horizontal plane under the action of the pressing rail 3 and the crank 4, and the two are relatively static, namely, the two form a plane for receiving the conveyed green pellets, as shown in fig. 2. When the green pellets finish the processes of drying, preheating, roasting and cooling in the area, the green pellets are agglomerated to form pellet ore. The roasted pellets enter a pellet discharging area 02, in which the revolving frame 1 moves to a concave section of the pressing rail 3, and at the moment, the crank 4 loses the limitation of the pressing rail 3 and loses the control on the fan-shaped trolley 2, so that the fan-shaped trolley is tipped by the dead weight, and pellets are discharged into a hopper. Since the width of the sectoral trolley 2 is only 2/3 of the width of the circular process section of the whole roasting machine, as shown in fig. 4, a part of the pellets on the revolving frame 1 does not fall into the ore tank. After the unloading is finished, the crank 4 of the sector trolley 2 is gradually restored to the horizontal state under the action of the pressure rail 3. When the fan-shaped trolley 2 completely enters a horizontal state, the fan-shaped trolley correspondingly enters a pellet bedding material area 03, and at the moment, pellets on the revolving frame 1 are paved on a grate plate of the ring-type trolley 2 through a material flattening device 9 to finish bedding material paving.
Preferably, the sector trolley 2 is connected with the mounting shaft 5 through a connecting key 7, the crank 3 is fixedly connected at one end of the mounting shaft 5, and the mounting shaft 5 is connected on the revolving frame 1 through a bearing 8. A specific connection mode is provided, and other connection modes can be selected according to different requirements in practice and are all within the protection range.
In a further embodiment, the cover ring type roasting machine further comprises a material flattening device 9 for flattening the pellets. And the material flattening device 9 can be arranged at the annular process section, and the pellets on the revolving frame 1 are flattened on the fan-shaped trolley 2 through the material flattening device 9 in the rotating process of the annular trolley 2.
Set up flat material device 9 to the V template in this application, and the pointed end of V template towards the direction of the operation of fan-shaped platform truck 2, so set up, can rotate the in-process at fan-shaped platform truck 2, accomplish flat material automatically.
In a further embodiment, the leveling device 9 is adjustable in height relative to the fan-shaped trolley. The pellets which do not fall into the ore tank on the revolving frame 1 are distributed to the middle by the material flattening device 9, as shown in fig. 5, until a layer of bedding material is formed on the pellets, thus realizing self-taking of the bedding material. The thickness of the bedding material can be adjusted by means of the material flattening device 9. During maintenance, the material leveling device 9 can be lowered to be tightly attached to the surface of the fan-shaped trolley, and pellets on the fan-shaped trolley 2 are unloaded to the greatest extent.
The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention.
