Description

TECHNICAL FIELD

[0001] The utility model belongs to the mixed technical field, concretely relates to a kind of batching mixing device for vanadium-titanium pellet production. BACKGROUND

[0002] Vanadium-titanium magnetite is an important mineral resource, and the production of vanadium-titanium pellets includes the following steps: raw material preparation: mining and crushing: first, mine the ore from the vanadium-titanium magnetite deposit and crush it to an appropriate particle size, usually less than 200 mesh powder; ore dressing: separate vanadium-titanium magnetite concentrate by magnetic separation and other methods; batching: mix the vanadium-titanium magnetite concentrate with an appropriate amount of binder and other additives, and ensure uniform distribution of the binder and additives; pelletizing: feed the mixed material into a pelletizer, and through rolling, the material forms pellets of a certain size under the action of mechanical force and capillary force; drying: reduce the moisture content to a level suitable for sintering or blast furnace use through drying equipment; preheating: the dried pellets usually need to be preheated to remove part of the crystal water before entering the high-temperature roasting; roasting: the preheated pellets are fed into a roasting device and roasted at high temperature to cause physical and chemical changes in the minerals in the pellets, forming pellets with good reducibility; cooling; finished product processing: the cooled pellets are screened to remove powder and oversized lumps, and the finished pellets that meet the requirements of blast furnace smelting are obtained.

[0003] After searching, the utility model patent with Chinese patent number CN219701649U discloses a raw material batching device for vanadium-titanium pellet production, which includes a stirring box. The upper surface of the stirring box is fixedly connected with a top cover. The upper surface of the top cover is fixedly connected with a first motor and a second motor respectively. The lower surface of the top cover is fixedly connected with a first bearing and a second bearing. The inner wall of the first bearing is fixedly connected with a threaded rod. By setting the square groove and the cylinder, the resistance encountered by the first blade during stirring and batching can be reduced, thereby improving the efficiency of stirring. By setting the second blade on the stirring shaft, the problem of some batching materials being unable to be stirred after entering the discharge pipe can be avoided, and the problem of the mixed raw materials blocking the discharge pipe during discharging can also be avoided. The rotation of the first motor output end drives the threaded rod to rotate, thereby causing the cleaning ring connected with the threaded rod to move up and down. When the cleaning ring moves up and down, it rubs the inner wall of the stirring box to clean the powder adhering to the inner wall of the stirring box.

[0004] Although this patent can clean the inner wall of the stirring box, it uses a threaded lifting method. The raw materials for vanadium-titanium pellet production can adhere to the threaded grooves of the threaded rod, causing jamming between the cleaning ring and the threaded rod, affecting the normal lifting of the cleaning ring. Therefore, a batching mixing device for vanadium-titanium pellet production is proposed. UTILITY MODEL CONTENTS
