Abstract

The invention relates to a stirring device which comprises a stirring container and a driving unit connected with the stirring container, wherein, a stirring paddle is installed in the stirring container, a drive shaft is arranged on the driving unit, a shaft coupling, a bearing, a sealing means and the stirring paddle are sequentially connected with the drive shaft from top to bottom, the sealing means is externally connected with an outboard gas source which is connected to a place where the sealing means and the drive shaft joins through a pipeline, and a through hole is provided on the outer wall of the driving unit for letting in the pipeline of the outboard gas source. According to the invention, the sealing means is externally connected with the outboard gas source, gas is used for sealing, powder is isolated by gas pressure, and the bearing rotating at a high speed is cooled; therefore, the bearing is protected, work environment is improved, and leakage of oil stains is prevented, achieving the effect of cleanness.

Description

Agitating device
Technical field
The present invention relates to a kind of agitating device.
Background technology
The agitating device failure reasons: sealing device 69%, permanent coupling 9%, bearing 10%, hydraulic system 3%, coupler 2%, other are 7% years old.So agitating device generally all is provided with mechanical seal, the effect of mechanical seal: 1. improve mechanical efficiency, cut down the consumption of energy; 2. save material; 3. raising machine reliability; 4. safety and environmental protection.For seal face being lubricated and cooling off, often select the double seals of hydrodynamic formula as the still sealing, feeding lubricating oil or lubricated better fluid are lubricated, cool off between two sealings.
The bearing of agitating device generally lubricates with grease or lubricating oil, guarantees the normal use of bearing, but under the situation of solid is arranged especially during powder-tight, solid leaks easily, makes powder get into the wearing and tearing that bearing has aggravated bearing, has shortened the service life of bearing.
In addition, in a single day mechanical seal break down when leaking, immediately parking maintenance; When equipment also in the running, the related personnel just should check to the scene immediately, examines the operating mode of equipment; The pressure flow of accessory system, an aspect factor such as the situation of leakage position and vibration equipment.
Summary of the invention
The technical problem that the present invention will solve is: based on the problems referred to above, the present invention provides a kind of powder of having isolated, and again the bearing under rotating is at a high speed cooled off the agitating device of protection bearing simultaneously.
The technical solution adopted for the present invention to solve the technical problems is: a kind of agitating device is provided; Comprise stirred vessel and be connected the transmission device on the stirred vessel; In the described stirred vessel paddle is installed; Described transmission device is provided with power transmission shaft; Be connected with shaft coupling on the power transmission shaft from top to bottom in turn; Bearing; Sealing device and paddle; Described sealing device is externally connected with external source of the gas; Described external source of the gas is connected to the junction of sealing device and power transmission shaft through pipeline, offers the through hole that the pipeline that supplies external source of the gas feeds on the described transmission device outer wall.
Further, described through hole is provided with the bolt of fixed-piping.
The invention has the beneficial effects as follows: sealing device of the present invention is externally connected with external source of the gas; The using gases sealing; Utilize gas pressure to isolate powder; Again the bearing under rotating is at a high speed cooled off simultaneously; Protected bearing; Also improve working environment, prevented the leakage of greasy dirt, reached clean effect.
Description of drawings
Embodiment further specifies the present invention below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the structure for amplifying sketch map at A place in this powder.
Among the figure: 1. stirred vessel, 2. transmission device, 3. paddle, 4. power transmission shaft, 5. shaft coupling, 6. bearing, 7. sealing device, 8. external source of the gas, 9. pipeline, the 10. junction of sealing device and power transmission shaft, 11. through holes.
The specific embodiment
Combine now specific embodiment that the present invention is described further, following examples are intended to illustrate the present invention rather than to further qualification of the present invention.
A kind of agitating device shown in Fig. 1~2; Comprise stirred vessel 1 and be connected the transmission device 2 on the stirred vessel 1; Paddle 3 is installed in the stirred vessel 1; Transmission device 2 is provided with power transmission shaft 4; Be connected with shaft coupling 5 on the power transmission shaft 4 from top to bottom in turn; Bearing 6; Sealing device 7 and paddle 3; Sealing device 7 is externally connected with external source of the gas 8; External source of the gas 8 is connected to the junction 10 of sealing device 7 and power transmission shaft 4 through pipeline 9; Promptly used air seal; Utilize gas pressure to isolate powder; Again the bearing 6 under rotating is at a high speed cooled off simultaneously, protected bearing 6; Offer the through hole 11 of pipeline 9 feedings that supply external source of the gas 8 on transmission device 2 outer walls.
Further, through hole 11 is provided with the bolt of fixed-piping 9.
With above-mentioned foundation desirable embodiment of the present invention is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
