the utility model relates to the technical field of cement production equipment, in particular to a scraping device of a cement vertical mill.
The background technology is as follows:
the vertical mill is an important device for grinding in cement production, and the scraping device of the vertical mill is mainly used for discharging coarse particles entering the scraping chamber out of the vertical mill in the process of grinding materials by the vertical mill, and the working principle is as follows: the motor drives the mill to rotate, wind enters the vertical mill from the air inlet, materials fall at the center of the mill from the feed opening, move towards the edge of the mill under the action of centrifugal force, are crushed by the mill rollers in the grinding area, continuously move to the edge of the mill to the wind ring, the finer materials are taken away by airflow, the larger materials and iron blocks fall into the lower shell of the mill from the wind ring, and enter the circulating elevator after being scraped into the feed back scraper-way by the scraping device fixed on the mill, and then are lifted into the mill scraper-way by the elevator to grind again. In the working process, the scraping device plays a vital role.
At present, a scraping device structure used by a vertical mill is shown in fig. 1, a scraping plate is fixedly arranged at the bottom of a scraping plate bracket, and the scraping device has the following problems in use: the accumulated materials between the lower part of the scraping plate and the millstone make the resistance of the scraping device large, so that the scraping plate frequently falls down and is damaged and deformed. When the scraping plate is damaged and deformed, repair welding and treatment are needed to be carried out on the scraping plate in time, otherwise, the lower shell of the mill is easy to wear, and material leakage is caused. The frequent repair welding causes a great deal of manpower and material resource waste, and the repair welding process flow is complex, the maintenance is inconvenient, and the normal production flow of the vertical mill is seriously affected.
The utility model comprises the following steps:
the utility model aims to provide a vertical mill scraping device which reduces the resistance of the lower part of a scraping plate, reduces the deformation of the scraping device and is convenient to replace.
The utility model is implemented by the following technical scheme: a scraping device of a cement vertical mill comprises a scraping plate bracket, a first scraping plate and a second scraping plate; one side of the lower part of the scraping plate support is detachably and fixedly connected with the first scraping plate, and the other side of the lower part of the scraping plate support is detachably and fixedly connected with the second scraping plate.
Preferably, the first scraping plate is connected with the lower part of the scraping plate support through a bolt, and the second scraping plate is connected with the scraping plate support through a bolt.
Preferably, the bottom edge of the first scraping plate is located above the bottom edge of the second scraping plate.
Preferably, the first scraping plate and the second scraping plate are provided with wear-resistant materials on the material facing surfaces.
Preferably, the upper parts of the first scraping plate and the second scraping plate are respectively provided with a chamfer.
The utility model has the advantages that: the two sides of the lower part of the scraping plate bracket are respectively and detachably fixedly connected with one scraping plate, and the bottoms of the two scraping plates are provided with height differences, so that the impact of material resistance between the grinding disc and the scraping plates on the scraping device is effectively reduced, and the deformation of the scraping plates in the scraping process is reduced; the scraping plate is connected with the scraping plate support through the bolts, when the scraping plate is damaged, the scraping plate can be replaced by disassembling the bolts, and the maintenance cost and the maintenance time are greatly reduced.
Description of the drawings:
in order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings that are required in the embodiments or the description of the prior art will be briefly described, it being obvious that the drawings in the following description are only some embodiments of the utility model, and that other drawings may be obtained according to these drawings without inventive effort for a person skilled in the art.
Fig. 1 is a structural view of a scraping device in the prior art.
Fig. 2 is a schematic structural diagram of a scraping device in embodiment 1 of the present utility model.
FIG. 3 is a cross-sectional view taken along the A-A plane in FIG. 2.
The scraper bracket 1, the first scraper 2, the second scraper 3 and the bolt 4.
The specific embodiment is as follows:
the following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Example 1:
the scraping device of the cement vertical mill comprises a scraping plate bracket 1, a first scraping plate 2 and a second scraping plate 3, wherein the scraping plate bracket is provided with a first scraping plate and a second scraping plate; wherein, the first scraper blade 2 of fixedly connected with can be dismantled to one side of scraper blade support 1 lower part, and the second scraper blade 3 of fixedly connected with can be dismantled to the opposite side of scraper blade support 1 lower part. The two sides of the lower part of the scraping plate bracket 1 are respectively provided with a scraping plate which is helpful for reducing the deformation of the scraping device in the scraping process.
Preferably, the bottom edge of the first scraper 2 is located above the bottom edge of the second scraper 3. In this embodiment, the height difference between the first scraping plate 2 and the second scraping plate 3 is 100mm, and the running resistance of each scraping plate in the scraping process is effectively reduced through the height difference of the scraping plates.
