Abstract
The invention discloses a separating bin of a ball mill and relates to the technical field of engineering machine equipment manufacturing. The separating bin comprises a grate plate, a blind plate and a lifting board which are arranged on a center rack; separating bin plate reinforcing plates are arranged on the back surface of the grate plate and are flush with the edge of the grate plate; the thickness of each separating bin plate reinforcing plate is 0.4-0.5 time that of the grate plate; all areas, corresponding to grate seams of the grate plate, of the separating bin plate reinforcing plates are empty; bolt holes of the separating bin plate reinforcing plates are concentric to bolt holes of the grate plate and the blind plate, and are smaller than the bolt holes of the grate plate. According to the separating bin of the ball mill, the problems that the grate plate of a separating bin device easily moves, the center rack is damaged, the maintenance intensity is high, the service lives of accessories are short, and the maintenance cost is high can be solved.
Description
Technical field
The present invention relates to cement machinery equipment manufacturing technology field, especially a kind of compartment for coarse grinding cabin of ball mill, transitional storehouse.
Background technology
In raw material preparation in cement production process, cement grinding process flow, use ball mill, in existing coarse grinding cabin of ball mill, transitional storehouse, adopt compartment; The device of ball mill is for meeting minute storehouse requirement, and the abrasive body that grinds interior different-diameter is separated, required to adapt to each storehouse grinding; Compartment includes the grate plate being fixed on the shelf of center, lifting blade and blind plate; Grate plate and blind plate are fixed on the shelf of center by coupling bolt; Wherein grate plate plays and blocks coarse granule, guarantees fineness, controls material flow, is beneficial to the effects such as mill inner ventilation; Grate plate is contained in the charging face in each storehouse, and it is just facing to the feed end of material, and the back side is center shelf, and shelf another side nestles up blind plate; Because the connection of grate plate and blind plate is leaned on the top of the shelf by bolted, in production process, under the continuous impact of abrasive body, bolt is easily loosening, and grate plate is easily shifted, even fracture; After grate plate fracture, rod iron or steel ball Cuan Jin center shelf, easily wash away shelf, and shelf is hit fragile; Therefore this compartment grate plate is shorter service life, and repair rate is high, and labour intensity is large, often needs to shut down to process, and wastes time and energy, and it is passive to production, to bring; Therefore protect grate plate to play an important role to the production of whole grinding machine.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of ball grinder, and it is short service life that it can solve in compartment grate plate, and repair rate is high causes the problem that production cost is high.
In order to address the above problem, technical scheme of the present invention is: this ball grinder includes the grate plate being arranged on the shelf of center, and blind plate and lifting blade are provided with partition panel gusset plate at the described grate plate back side; Described partition panel gusset plate is mutually neat with the edge of described grate plate, and the 0.4-0.5 of the thickness that described partition panel gusset plate thickness is described grate plate doubly; It is all empty that described partition panel gusset plate stitches corresponding region with the comb of described grate plate, its bolt hole and grate plate and the same center of blind plate bolt hole, and its bolt hole is less than the bolt hole of grate plate.
In technique scheme, more specifically scheme can also be: described partition panel gusset plate quantity is 16, and a grate plate of the corresponding connection of each piece partition panel gusset plate, a lifting blade every the crimping of two partition panel gusset plates.
Further: described grate plate and described partition panel gusset plate and blind plate are fixed on the shelf of center by coupling bolt, and coupling bolt head sinks in grate plate plate face.
Owing to adopting technique scheme, the present invention has following beneficial effect:
1, the present invention increases partition panel gusset plate on grate plate, and in use procedure, coupling bolt is reinforced plate hole and fixes, and is difficult for displacement; Each piece grate plate has two coupling bolts, by the fixation of partition panel gusset plate, even if grate plate breaks in half, also can also continue to use, and has increased the service life of grate plate; Reduce maintenance; Improved production efficiency.
2, the present invention is simple in structure, has solved the problem that former partition device for barn grate plate is easily shifted, center shelf damages, maintenance intensity is large, the accessory life-span is short, the cost of overhaul is high, and practical function is fine.

The specific embodiment
Below in conjunction with drawings and Examples, the present invention is further described:
The ball grinder of Fig. 1 and Fig. 2, includes the grate plate 4 being arranged on center shelf 7, blind plate 9 and lifting blade 5; At the back side of grate plate 4, be provided with partition panel gusset plate 3.Ball grinder is fixedly installed in ball mill barrel 1, ball mill barrel 1 inwall circumferential directions one circle shell liner 2, lifting blade base ring 6 is bolted on the shell liner 2 with cylindrical shell 1 support and connection, lifting blade 5 bottoms are bolted on lifting blade base ring 6, and lifting blade 5 other ends are bolted on center shelf 7; Every the 3 side crimping of two partition panel gusset plates, a lifting blade 5, guarantee that coupling bolt 8 is not blocked by lifting blade 5; Partition panel gusset plate 3 is mutually neat with the edge of grate plate 4, partition panel gusset plate 3 thickness be grate plate 4 thickness 0.4-0.5 doubly, as shown in Figure 3 and Figure 4; Partition panel gusset plate 3 stitches corresponding region with the comb of grate plate 4 and all hollows out, and while guaranteeing to produce, mill discharge is not blocked by partition panel gusset plate 3; Partition panel gusset plate 3 bolts hole and grate plate 4 and the blind plate 9 same centers of bolt hole, as Fig. 3, shown in Fig. 4 and Fig. 5, the bolt hole of partition panel gusset plate 3 is more smaller than the bolt hole of grate plate, is 0.75 times of the bolt hole of grate plate; The quantity of partition panel gusset plate 3 is consistent with grate plate 4 quantity, each 16, only marks wherein 4, the position that all the other only mark set bolt hole site and draw 4 partition panel gusset plates 3 with chain-dotted line in Fig. 1; 16 partition panel gusset plates 3 are installed successively, and the tail end of each piece partition panel gusset plate 3 is welded on lifting blade base ring 6, and head end is welded on center shelf 7.Between each piece partition panel gusset plate 3, overleaf its side is all welded; After partition panel gusset plate 3 all welds well, on corresponding partition panel gusset plate 3 fronts, grate plate 4 is installed, the rear installation blind plate 9 of center shelf 7 at partition panel gusset plate 4 back sides, by coupling bolt, tighten up, guarantee the corresponding grate plate 4 of each piece partition panel gusset plate 3 and blind plate 9, do not affect grinding machine and normally work; Coupling bolt head sinks in grate plate plate face, bolt is difficult for loosening.
The present invention adopts increases gusset plate on the grate plate back side, can protect grate plate, increase the service life, reduces maintenance, enhances productivity.
