Abstract
The utility model relates to a stirring device, which comprises a stirring container and a transmission device connected onto the stirring container. A stirring paddle is mounted in the stirring container, a transmission shaft is arranged on the transmission device and connected with a coupler, a bearing, a sealing device and the stirring paddle sequentially from top to bottom, and an external gas source is connected outside the sealing device and connected to the junction of the sealing device and the transmission shaft through a pipeline. Gas is used for sealing, gas pressure is used for isolating powder, the bearing rotating at a high speed is cooled so as to be protected, working environments are improved, leakage of greasy dirt is prevented, and cleanness is achieved.
Description
Technical field
The utility model 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.In order seal face to be lubricated and to cool off, often select the double seals of hydrodynamic formula to use sealing as still, 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.
The utility model content
The technical problem that the utility model will solve is: based on the problems referred to above, a kind of powder of having isolated is provided, again the bearing under rotating is at a high speed cooled off simultaneously, the agitating device of protection bearing.
The utility model solves the technical scheme that its technical problem adopted: a kind of agitating device; 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, is connected with shaft coupling, bearing, sealing device and paddle on the power transmission shaft from top to bottom in turn; Described sealing device is externally connected with external source of the gas, and described external source of the gas is connected to the junction of sealing device and power transmission shaft through pipeline.
Further, offer the through hole of the pipeline feeding that supplies external source of the gas on the described transmission device outer wall.
Further, described through hole is provided with the bolt of fixed-piping.
The beneficial effect of the utility model is: the sealing device of the utility model is externally connected with external source of the gas; The using gases sealing utilizes 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
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
