Abstract
The utility model relates to the grate plate device in cement grinding mill, specifically a kind of anti-blocking, easy to clean cement grinding mill discharge grid plate device.Comprise grate plate, grate plate frame, connecting bolt, described grate plate is the sheet metal with the oval elongated hole type comb seam be evenly distributed, be provided with backplate outside described grate plate, on described backplate, the comb seam part of corresponding grate plate is void region, and backplate and grate plate form split-type structural.The utility model protects grate plate by backplate, makes grate plate reduce friction, reduces abrasive body in mill running process simultaneously and is stuck in the situation that seam of combing causes seam blocking of combing, improve production efficiency, reduce production cost; Grate plate and backplate structure are split-type structural, make the installation of grate plate, maintenance, repair convenient.
Description
Technical field
The utility model relates to the grate plate device in cement grinding mill, specifically a kind of anti-blocking, easy to clean cement grinding mill discharge grid plate device.
Background technology
Grate plate in existing cement grinding mill is steel-casting, thick and heavy, seam of particularly combing adopts bell-mouthed form, when there being the abrasive body of broken abrasive body or minor diameter in grinding, abrasive body will along with the flow direction of the wind in mill, be stuck in bell-mouthed comb seam, thus decrease draught area, affect the production capacity of grinding machine; Simultaneously because grate plate is thick and heavy, the size of seam of combing can not be too little, otherwise cannot complete casting technique, result also in the roomy of seam of combing, more easily have little abrasive body to stick into.Therefore, regularly must enter in mill and carry out cleaning comb seam, high owing to grinding interior temperature, be unfavorable for carrying out the work, and the grate plate dismounting of heaviness is very inconvenient, cause labour intensity large, maintenance cost increases.
Utility model content
The utility model is intended to solve the problem, thus provide one avoid abrasive body be stuck in comb seam in causing comb seam blocking, and installation, maintenance, repair, cleaning anti-blocking, easy to clean cement grinding mill discharge grid plate device easily.
The technical scheme that the utility model solves the employing of its technical problem is:
A kind of anti-blocking, easy to clean cement grinding mill discharge grid plate device, comprise grate plate, grate plate frame, connecting bolt, described grate plate is the sheet metal with the oval elongated hole type comb seam be evenly distributed, outside described grate plate, backplate is installed, on described backplate, the comb seam part of corresponding grate plate is void region, and backplate and grate plate form split-type structural.
Adopt the utility model of technique scheme, compared with prior art, its beneficial effect is:
Due to the sheet metal that grate plate is band oval elongated hole type comb seam, and the backplate with hollow type structure is installed in outside, thus play the effect that protection grate plate reduces friction, meanwhile, owing to having backplate to protect grate plate, thus can by grate plate lower thickness, be conducive to processing small size comb seam, decrease abrasive body in mill running process by this structure and be stuck in the situation that seam of combing causes seam blocking of combing, improve production efficiency, reduce production cost; Grate plate and backplate are split-type structural, relative to originally thick and heavy foundry goods grate plate, more easily remove and install, easy to maintenance.
As preferably, the utility model further technical scheme is:
The comb seam area of described grate plate is determined according to mill inner ventilation wind speed and draught area, and seam width of combing is determined according to the abrasive body diameter in mill.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is grate plate structural representation;
Fig. 3 is guard board structure schematic diagram;
In figure: backplate 1, grate plate 2, grate plate frame 3, connecting bolt 4, comb seam 5, void region 6.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further elaborated, but embodiment does not form any restriction to the utility model.
See Fig. 1, Fig. 2, Fig. 3, grate plate 2 is the sheet metals with the oval elongated hole type comb seam 5 be evenly distributed, and comb seam 5 is through punch forming; Backplate 1 is steel-casting, on backplate 1, the comb of corresponding grate plate 2 stitches 5 parts is void region 6, backplate 1 is arranged on outside grate plate 2, and by connecting bolt 4 integral installation in grate plate frame 3 side of frame structure, comb seam 5 area is determined according to mill inner ventilation wind speed and draught area, and comb seam 5 width is determined according to the abrasive body diameter in mill.
The discharge grid plate device of said structure, owing to having backplate 1 to protect grate plate 2, decreases the wearing and tearing of grate plate 2, thus can by the lower thickness of grate plate 2, and comb seam 5 processing in such grate plate 2 is got up convenient.This structure decreases abrasive body in mill running process and is stuck in the situation that comb seam 5 causes comb seam 5 to block, and improves production efficiency, reduces production cost, improves the unit-hour output of grinding machine.The simultaneously split-type structural that forms of backplate 1 and grate plate 2, also makes the installation of grate plate 2, maintenance, repair very convenient.
Claims (2)
1. anti-blocking, an easy to clean cement grinding mill discharge grid plate device, comprise grate plate, grate plate frame, connecting bolt, it is characterized in that, described grate plate is the sheet metal with the oval elongated hole type comb seam be evenly distributed, outside described grate plate, backplate is installed, on described backplate, the comb seam part of corresponding grate plate is void region, and backplate and grate plate form split-type structural.
2. anti-blocking, easy to clean cement grinding mill discharge grid plate device according to claim 1, is characterized in that, the comb seam area of described grate plate is determined according to mill inner ventilation wind speed and draught area, and seam width of combing is determined according to the abrasive body diameter in mill.
