Abstract
The utility model relates to a split type millstone of a vertical roller mill, which is characterized by comprising an upper disk body and a lower disk body. The upper disk body and the lower disk body are connected by key location and fasteners to form a millstone disk body, and a lining plate capable of being used as a working material bed is fixedly mounted in the upper disk. The split type millstone of vertical roller mill has the advantages that the millstone disk body is produced in a manner of being divided into the upper disk body and the lower disk body, the upper disk body directly bears the load and impact from a milling roller, thus, only the upper disk body generates cracks, normal production can be resumed just by changing the upper disk body instead of changing the whole millstone disk body. Therefore, manufacturing difficulties and workload can be reduced greatly, and quality inspection is facilitated; moreover, weight of the millstone of a large vertical mill can be reduced, and meanwhile, the convenience is brought for transport and field installation greatly.
Description
Technical field
This patent belongs to solid particle milling equipment field, particularly relates to a kind of vertical roller grinder split mill.
Background technology
Vertical roller grinder is to be widely used at present cement, electric power, a kind of energy-conservation milling equipment of the industries such as iron and steel, the parts that the vertical roller grinder mill is main participation material grinding.Oil cylinder power passes to grinding roller by rocking arm and finally is applied on mill, realizes the grinding to material.Mill partly bears all from the grinding power of grinding roller, and grinding power is delivered to reductor by mill again, then is delivered to concrete foundation.Because mill is partly bearing the torque from reductor, so mill is partly stressed and workpiece crucial in vertical roller grinder.
The critical piece of mill is divided into liner plate and disk body, the parts that liner plate is milling zone, and liner plate is arranged on disk body, and disk body is stressed member.Because the vertical roller grinder operating mode is very complicated, disk body should bear the thermal stress of bearing again Self-air-heating from the grinding power of grinding roller, and wherein hot blast is material drying indispensability in vertical roller grinder.Can cause in addition the vibration of grinding machine due to the unstability of the bed of material, and the situation of grinding roller and mill Metal Contact appears in too thin bed of material occasional.In production in the past, the situation of the improper disk body cracking caused of casting flaw, fault in material or execute-in-place due to mill once occurred, and crack can be extended gradually along with fatigue.It is very large changing the workload of disk body in the vertical roller grinder maintenance, and needs the very long repair time of cost, can bring serious negative effect to user's benefit like this.The development of modern grinding machine is the Enlargement Tendency, the mill of maximization grinding machine must be that diameter is large and highly high, for the work such as casting, processing and quality inspection all bring difficulty, therefore the structure optimization of mill disk body, reduce such problem as far as possible and the loss brought occurs, become a problem important and urgently to be resolved hurrily.
Summary of the invention
This patent provides a kind of vertical roller grinder split mill for solving the technical problem existed in known technology.
This vertical roller grinder split mill is not only simple in structure, reasonable in design, can significantly alleviate the whole replacing disk bodies that cause because of disk body one place's cracking and bring the hard work amount, but also have, is convenient to transportation and field erected advantage.
The technical scheme that this patent is taked for the technical problem existed in the solution known technology is:
Vertical roller grinder split mill, comprise disk body and lower disk body, and described upper disk body and lower disk body are located by key and securing member connects and composes the mill disk body, is fixed with the liner plate that can play the effect of work material bed in described upper disk body.
This patent can also adopt following technical scheme:
Described upper disk body bottom all is shaped with for being connected the seam of location with lower disk body top, and is fixedly connected with arch key location and bolt by seam.
Described upper disk body inner surface for place liner plate and and horizontal plane between be the conical surface at inclination angle.
Described liner plate is packed on upper disk body inwall by alignment pin, and pushes down liner plate by briquetting.
Advantage and good effect that this patent has are: because this patent adopts technique scheme, the mill disk body is decomposed into to upper disk body and the making of lower disk body two parts, make tray body direct receive load and the impact from grinding roller, therefore only cause disk body to produce crack, only replace with disk body and just can recover normal production, without changing whole mill disk body.So not only can greatly reduce to manufacture difficulty and workload, for quality inspection facilitates; But also can reduce the weight of the mill of maximization vertical roller grinder, bring very big facility for transportation and on-the-spot the installation simultaneously.
The accompanying drawing explanation
Fig. 1 is the structural representation of this patent;
Fig. 2 is the I section enlarged drawing in Fig. 1;
Fig. 3 is the structural representation of disk body on this patent;
Fig. 4 is the structural representation of disk body under this patent.
In figure: 1, liner plate; 2, upper disk body; 2-1, upper disk body lower surface; 3, alignment pin; 4, briquetting; 5, bolt; 6, the first arch key; 7, lower disk body; 7-1, lower disk body upper surface; 8, the second arch key.
The specific embodiment
For further understanding summary of the invention, the Characteristic of this patent, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1-Fig. 4, vertical roller grinder split mill, comprise disk body 2 and lower disk body 7, and described upper disk body and lower disk body are located by key and securing member connects and composes the mill disk body, is fixed with the liner plate 1 that can play the effect of work material bed in described upper disk body.
In the present embodiment, described upper disk body inner surface for place liner plate and and horizontal plane between be the conical surface at inclination angle, described liner plate is packed on upper disk body inwall by alignment pin 3, upper disc surfaces is provided with four for the fixing pin-and-hole of liner plate, and pushes down liner plate by briquetting 4, to prevent it, circumferential play occurs.
In the present embodiment, described upper disk body bottom all is shaped with for being connected the seam of location with lower disk body top, by seam and the first arch key 6 location, lower disk body upper surface 7-1 is contacted fully with upper disk body lower surface 2-1, and be fixedly connected with by bolt 5.
The mill consisted of upper disk body 2 and lower disk body 7 is installed together by the second arch key 8, studs and grinding machine main gear reducer scene.Described the first arch key 6 and the second arch key 8 all play the effect of location transmitting torque.
Described lower disk body is connected with reductor and bears thermal stress, and upper disk body bears the grinding power from grinding roller, and reductor drives upper disk body rotation by lower disk body, reaches the purpose that material is thrown to the mill edge.
In addition, it should be noted that, the particular content described in this specification is conducive to help to understand the design core concept of this patent, not its design and scope is limited.Under the prerequisite that does not break away from this patent scheme, various the supplementing or modification that those skilled in the art makes described specific embodiment, all should belong to the protection domain of this patent.
