Description
Technical Field
The utility model relates to the technical field of grinding of materials, in particular to a machine-made sand vertical grinding and scraping device.
Background
The machine-made sand vertical mill integrates the functions of grinding, homogenizing, drying and conveying. Because the grinding mechanism of the machine-made sand vertical mill is simple, the operation is convenient, the requirements on materials are low, and the like, the vertical mill is widely applied in recent years. The premise of long-time stable operation of the vertical mill is that the vertical mill is provided with the milling and scraping device which is convenient to install and has a firm structure.
Present vertical mill scrapes flitch, as shown in fig. 1, scrape material frame 5 and scrape flitch 6 and be connected through connecting piece 2, the problem that its exists is that the vertical mill system sand is less than the operating pressure who makes the powder relatively, consequently it is great to exist in the material granule of scraping the material interval, it is less to scrape the clearance between flitch 6 and the casing bottom plate 4, the phenomenon of blocking appears very easily when the granule is great, connecting piece 2 is not hard up can appear in long-time running, it drops the safety in production that influences the mill to scrape flitch 6, can lead to entire system's damage even.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is to provide a machine-made sand vertical grinding and scraping device which is convenient to install and maintain and has higher safety performance.
In order to achieve the purpose, the technical scheme adopted by the utility model is as follows:
the utility model provides a vertical mill scraper of mechanism sand, includes scrapes the work or material rest and scrapes the flitch, wherein scrape the work or material rest and include roof and fixed plate, scrape and be connected through the connecting piece between flitch and the fixed plate, scrape and be equipped with the border that extends to one side on the flitch, be equipped with on the roof with scrape the positioning mechanism of border location joint on the flitch, scrape the flitch and pass through the connecting piece and the positioning mechanism at border two at least connecting points of locating mechanism with scrape the work or material rest and be connected fixedly.
Preferably, the positioning mechanism comprises a limiting plate connected to the lower end face of the top plate, a connecting portion extending to one side of the edge of the scraping plate is arranged on the limiting plate, the connecting portion and the edge are provided with overlapping positions, and the connecting portion is connected with the edge.
Preferably, the connecting part is arranged below the edge.
Preferably, the upper end of the connecting part is provided with a limiting pin, and the edge of the connecting part is provided with a clamping hole clamped on the positioning pin.
Preferably, the whole limiting plate is of an L-shaped structure.
Preferably, the scraper plate is of an L-shaped structure as a whole.
The utility model has the beneficial effects that: the utility model increases the connecting strength between the scraping plate and the scraping frame by adding the positioning mechanism, the connecting piece is not easy to loosen, the scraping plate is not easy to fall off, and the system maintenance rate is reduced.

Detailed Description
The present invention will be further described with reference to the following examples.
The vertical abrasive scraping device for machine-made sand comprises a scraping frame 1 and a scraping plate 3, wherein the scraping frame comprises a top plate 7 and a fixed plate 10, the upper end of the fixed plate is fixed on the lower end face of the top plate, a plurality of holes are formed in the fixed plate, the plurality of holes are also formed in the scraping plate and correspond to the hole positions in the fixed plate, the scraping plate 3 is connected with the fixed plate 10 through a connecting piece 2, the connecting piece is a bolt or a rivet, an edge extending towards one side is formed in the scraping plate 3, a positioning mechanism which is in positioning clamping connection with the edge on the scraping plate 3 is arranged on the top plate 7, and the scraping plate 3 is fixedly connected with the scraping frame 1 through at least two connecting points of the connecting piece 2 and the positioning mechanism at the edge. In this embodiment the positioning mechanism including connect the limiting plate 8 on the terminal surface under roof 7, be equipped with on the limiting plate 8 to scraping the connecting portion that flitch 3 border one side extended, connecting portion have with the border and overlap the position, and connecting portion are connected with the border. In this embodiment, the connecting portion is located below the edge, the upper end of the connecting portion is provided with the limiting pin 9, the limiting pin 9 is welded and fixed to the limiting plate 8, the number of the limiting pins is 3-10, the edge is provided with clamping holes clamped on the positioning pins, and the number of the clamping holes is equal to the number of the limiting pins. The whole limiting plate is of an L-shaped structure. The whole scraper plate is of an L-shaped structure. In this embodiment because scrape the flitch and scrape and have a plurality of junctions between the material frame to increased joint strength between them, just even having the large granule to block between scraping flitch and the casing bottom plate 4, also only can will scrape flitch 3 extrusion deformation, can not cause the damage of junction, thereby can not cause scraping droing of flitch 3.
The foregoing shows and describes the general principles, essential features, and advantages of the utility model. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to explain the principles of the utility model, and that various modifications and alterations can be made by those skilled in the art without departing from the spirit and scope of the utility model.
