Abstract
The utility model discloses an autogenous grinder discharging dustpan plate, including a dustpan body. The dustpan body consists of a dustpan shaped dustpan casing made of the material of carbon steel, and an attritionresistant protective layer made of the material of rubber. The utility model solves the abrasion of quartz sand to the carbon steel dustpan casing, and the pollution of produced iron chips to the products, improves the product quality, simultaneously reduces the dustpan plate weight, and is of great advantage to the use of people.
Description
Technical field
The utility model relates to a kind of technical field of autogenous tumbling mill, especially relates to the discharge plate of automatic mill that discharge is used on a kind of autogenous tumbling mill.
Background technology
Autogenous tumbling mill is as a kind of run-of-mine-milling equipment that relies on quartz sand self to impact mutually, grind and pulverize, having need not medium, feeding granularity scope big (can reach 600mm), the output height, advantages such as discharge is even, in the ore in sand form processing industry, obtained in the processing as quartz sand using very widely.But the applied autogenous tumbling mill of current people, it is some ferrous materials that the material that parts adopted on it mostly is, as the discharge dustpan plate that adopts ductile cast iron material to make, not only the material of Shi Yonging is more, and because the characteristics of its work, wooden partition is also thicker, caused the weight of dustpan plate also bigger, this is using and unusual inconvenience during dismounting, and adopt this discharge dustpan plate when quartz sand being processed processing, the dustpan plate can and cause wearing and tearing with the frequent generation of quartz sand particle bump, cause waste, and the iron filings that dustpan plate wearing and tearing are produced will be incorporated in the middle of the quartz sand product of being processed, the iron-holder in the product is increased greatly, product is polluted, influence the quality of product, and quartz sand is that iron-holder is required than higher a kind of product, so this just needs to adopt additional operation and method to remove these iron filings again, this has increased production cost of products to a certain extent, has reduced production efficiency.
Summary of the invention
The technical problems to be solved in the utility model has provided a kind of discharge plate of automatic mill, and it has effectively solved the pollution of the iron filings of quartz sand and its wearing and tearing generation to product, and weight is lighter, and is very convenient when use and dismounting.
For solving the problems of the technologies described above, the technical solution of the utility model is: discharge plate of automatic mill, comprise dustpan plate body, and described dustpan plate body comprises the dustpan housing of dustpan shape, is coated with wear-resistant protective layer on the inner surface of dustpan housing.
As a kind of improvement, described wear-resistant protective layer is a wear-resistant rubber sheet.
As further improvement, described wear-resistant rubber sheet and dustpan housing bonding are fixing.
As further improvement, described dustpan housing is a carbon steel dustpan housing.
Adopt the said structure discharge plate of automatic mill, owing to be to have adopted on the inner surface of dustpan housing of dustpan shape to be coated with a kind of like this composite construction of wear-resistant protective layer, make that at this discharge of use dustpan plate quartz sand being carried out autogenous grinding adds man-hour, quartz sand particle only with wear-resistant protective layer generation brinelling, this has just been avoided the wearing and tearing of dustpan housing and the generation of iron filings, and the content that reaches the iron in the reduction quartz sand product is to improve the purpose of quartz sand product quality; And reduced the weight of dustpan plate, helped the use of people it.Adopt wear-resistant protective layer that wear-resistant rubber sheet makes and be the shell that material is made, not only make the dustpan plate have enough intensity, and have long service life with the carbon steel.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described:
Fig. 1 is a discharge plate of automatic mill front view of the present utility model;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is that the A---A of Fig. 2 is to cutaway view;
Fig. 4 is the scheme of installation of dustpan plate on autogenous tumbling mill.
The specific embodiment
With reference to Fig. 4, discharge end one side circumferential array is equipped with some dustpan plates 1 in autogenous tumbling mill mill tube 2, on the direction of carrying along quartz sand, the upstream that is positioned at dustpan plate 1 is provided with the grate 3 that can screen the quartz sand particle after the autogenous grinding, the downstream that is positioned at dustpan plate 1 then is provided with the discharge barrel 4 that the quartz sand particle that dustpan plate 1 is carried can be discharged autogenous tumbling mill, is provided with the self-return screen that the quartz sand of larger particles can be carried back again in the autogenous tumbling mill mill tube 2 in the discharge barrel 4.Because the quartz sand particle in the autogenous tumbling mill mill tube 2 constantly enters into dustpan plate 1 through after the screening of grate 3, to be transported in the discharge barrel 4 by dustpan plate 1, therefore dustpan plate 1 can and cause serious wearing and tearing with the frequent generation bump of quartz sand particle, therefore, just need dustpan plate 1 to have enough intensity, this has caused dustpan plate 1 to have thicker wooden partition, make that the weight of dustpan plate 1 is bigger, this is using and unusual inconvenience during dismounting, the iron filings that dustpan plate 1 wearing and tearing are simultaneously produced will be incorporated in the middle of the quartz sand product of being processed, the quartz sand product is polluted, influence the quality of quartz sand product.
Therefore; in the utility model, adopted the discharge dustpan plate 1 as shown in Fig. 1, Fig. 2 and Fig. 3; include dustpan plate body; and dustpan plate body comprises the dustpan housing 11 of dustpan shape; inner surface at dustpan housing 11 is coated with wear-resistant protective layer 12; in order to make the dustpan plate have enough intensity and long service life; wear-resistant protective layer 12 can be wear-resistant rubber sheet; and dustpan housing 11 can be carbon steel dustpan housing, can make rubber-steel combined type dustpan plate by the bonding fixed form between wear-resistant rubber sheet and the carbon steel material dustpan housing.Like this; make wear-resistant protective layer 12 by wear-resistant rubber sheet; the dustpan housing 11 that will be material with the carbon steel separates with quartz sand particle; quartz sand particle only clashes into wear-resistant rubber sheet like this; this has just been avoided the wearing and tearing of carbon steel dustpan housing; with of the pollution of generation iron filings, improved the quality of product to product.And, can adopt thick carbon steel dustpan housing and the thick abrasive rubber flaggy of 12mm of 8mm to make this discharge dustpan plate according to the actual conditions in producing, the weight that this can greatly reduce the dustpan plate helps the use of people to it.
Discharge plate of automatic mill in the utility model not only is applied on the autogenous tumbling mill in the quartz sand processing industry, equally also can be applied on the autogenous tumbling mill that carries out autogenous grinding processing of other products such as ore, slag, ballstone, and have same function and effect.
