Abstract
The patent relates to an improved structure of a grinding roller sealing frame. The improved structure comprises a mill shell, a first sealing layer and a second sealing layer, wherein the first sealing layer is composed of the grinding roller sealing frame and a grinding roller arranged on the mill shell in a sealing manner; a non-ventilation flexible sealing member is adopted as the second sealing layer; the inner edge of the non-ventilation flexible sealing member is connected with the grinding roller sealing frame in the sealing manner, and the outer edge of the non-ventilation flexible sealing member is connected with the mill shell; the mill shell and the non-ventilation flexible sealing member form a cavity, isolated from external air, of the mill. The improved structure has the advantages that the shaking grinding roller is connected with a middle shell together through flexible non-ventilation industrial canvas, so that the cavity is isolated from the external air under the condition that normal working conditions of the mill are not influenced, thus the air leakage of the mill is reduced so as to achieve an effect of sealing. The improved structure is simple and feasible, convenient to disassemble and adjust and low in manufacturing and maintenance costs, the service life of an original grinding roller sealing frame can be prolonged, the equipment utilization rate of the original grinding roller sealing frame can be improved, the unit power consumption of the mill can be reduced, and the improved structure has considerable economic benefit.
Description
Technical field
This patent belongs to the grinding machine technical field, particularly relates to a kind of grinding roller sealing frame and improves structure.
Background technology
The vertical mill that is widely used in pulverized coal preparation system in the industries such as building materials, generating, mine, metallurgy, chemical industry and nonmetallic ore integrates fragmentation, drying, grinding, classification and carries, production efficiency is high, and bulk, graininess and powder raw material can be worn into to desired granular material.But Vertical Mill grinding lime stone, the raw materials such as grog, slag, slag, coal.At present, the grinding roller of vertical mill sealing frame is arranged on the junction of middle shell door and grinding roller sealing, and while working due to grinding machine; rocking arm can swing up and down, because the sealing frame side plate is wearing plate, its surface is very coarse; after experience wear, sealing joint strip can leave gap in the sealing frame contact site, causes grinding machine to leak out.In view of vertical mill system as advanced grinding system, whole system is more and more to large scale development, and its needed fan delivery is all very large, and in the mill of grinding machine, static pressure is also increasing thereupon, thereby grinding roller sealing frame air leakage phenomena is along with grinding machine maximizes more and more outstanding.In addition, because leaking out of grinding roller sealing frame had influence on mill efficiency and the grinding efficiency of temperature in the mill of grinding machine and grinding machine, therefore cause the unit power consumption of grinding machine to raise.
Summary of the invention
This patent provides a kind of grinding roller sealing frame to improve structure for solving the technical problem existed in known technology.
This grinding roller sealing frame improves structure and links together by flexible, non-gas permeability flat duck by the grinding roller by rocking and mesochite, it is isolated with ambient atmosphere not affecting under the grinding machine normal running conditions, reduce the air quantity that leaks out of grinding machine, reached the effect of sealing.
The technical scheme that this patent is taked for the technical problem existed in the solution known technology is:
Comprise grinding machine shell and the first sealant, the first sealant consists of grinding roller sealing frame and the grinding roller sealing be arranged on grinding machine shell, it is characterized in that:
Also comprise the second sealant, the second sealant is non-ventilative flexible seals, and non-ventilative flexible seals inward flange and grinding roller sealing frame are tightly connected, and outward flange is connected with grinding machine shell;
This patent can also adopt following technical scheme:
Described non-ventilative flexible seals adopts flat duck to make.
Described non-ventilative flexible seals one end is tightly connected by pressing plate and screw and grinding machine shell, and the other end is tightly connected by pressing plate and screw and grinding roller sealing frame.
Advantage and good effect that this patent has are: because this patent adopts technique scheme, by the grinding roller by rocking and mesochite, by flexible, non-gas permeability flat duck, link together, it is isolated with ambient atmosphere not affecting under the grinding machine normal running conditions, reduce the air quantity that leaks out of grinding machine, reached the effect of sealing.It is simple in structure feasible that this sealing frame improves, and dismounting and easy to adjust and manufacture and maintenance cost are cheap, not only can improve service life and the utilization rate of equipment and installations of former grinding roller sealing frame, but also can reduce the Mill Unit power consumption, have considerable economic benefit.
The accompanying drawing explanation
Fig. 1 is the structural representation of this patent;
Fig. 2 is that this patent is used view.
In figure: 1, non-ventilative flexible seals; 2, grinding roller sealing; 3, grinding machine shell; 4, grinding roller sealing frame; 5, grinding roller.
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 and Fig. 2, a kind of grinding roller sealing frame improves structure, comprises grinding machine shell and the first sealant, and the first sealant consists of grinding roller sealing frame 4 and the grinding roller sealing 2 be arranged on grinding machine shell 3; Also comprise the second sealant, the second sealant is non-ventilative flexible seals 1, and non-ventilative flexible seals inward flange and grinding roller sealing frame are tightly connected, and outward flange is connected with grinding machine shell; Grinding machine shell and non-ventilative flexible seals have formed grinding machine and the isolated cavity of ambient atmosphere.In the present embodiment, described non-ventilative flexible seals 1 adopts flat duck to make.It is not being affected under the grinding machine normal running conditions and the ambient atmosphere isolation, reach the effect of sealing.
In the present embodiment, described non-ventilative flexible seals outward flange is tightly connected by pressing plate and screw and grinding machine shell, and inward flange is tightly connected by pressing plate and screw and grinding roller sealing frame.
Refer to Fig. 1, the operation principle of this patent is:
Grinding machine is after normal operation a period of time, wearing and tearing due to adhesive tape in grinding roller sealing 2, there is gap between former grinding roller sealing 2 and grinding roller sealing frame 4, cause grinding machine to occur leaking out, and now, the cavity formed by non-ventilative flexible seals 1 and grinding machine shell, and the grinding roller 5 rocked is linked together by non-ventilative flexible seals 1 with mesochite, can make it not affect under the grinding machine normal running conditions and the ambient atmosphere isolation, thereby play the effect of secondary seal.
Although the above is described the preferred embodiment of this patent by reference to the accompanying drawings; but this patent is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment is only schematic; be not restrictive; those of ordinary skill in the art is under the enlightenment of this patent; not breaking away from the scope situation that this patent aim and claim protect, can also make a lot of forms.Within above-mentioned these all belong to the protection domain of this patent.
