Description
Technical Field
The utility model belongs to the technical field of sealing device technique and specifically relates to a novel buggy receive whitewashed ware sealing device that says so.
Background
At present, most of domestic pulverized coal powder collecting devices adopt a gas box pulse cloth bag powder collecting device, the powder collecting device is formed by combining a plurality of powder collecting chambers, pulverized coal-containing flue gas enters the powder collecting device from a flue gas inlet of the powder collecting device, gradually fills all the powder collecting chambers, enters a clean room from an air outlet of the powder collecting chamber under the guidance of a system fan, and then is discharged into the atmosphere from a flue gas outlet. The flue gas containing coal dust enters each powder collecting chamber, the cloth bags in the powder collecting chambers filter the coal dust to collect the coal dust on the outer surfaces of the cloth bags in the powder collecting chambers, and the coal dust adhered on the outer surfaces of the cloth bags is blown and falls into an ash hopper of a powder collector under the double actions of shaking by the pulse valve arranged on the clean room of each powder collecting chamber and the pulsation formed by the continuous opening and closing of the chamber valve plate driven by the chamber separating cylinder. When the chamber-separating cylinder is opened, the pulse valve cleans the coal dust adhered on the cloth bag, and when the chamber-separating cylinder is closed, the cloth bag of the powder collecting chamber filters the flue gas containing the coal dust entering the powder collecting chamber.
The chambered valve plate that the locular cylinder drove becomes to cut off between toilet and the filter chamber and unblocked door, and the tight degree of sealing of this door directly influences receives the powder effect, and along with the gradual improvement of national environmental standard and the black colour of buggy, the tight degree of sealing will surpass national environmental standard and influence and discharge the impression. The influence of ageing and the continuous start-stop of valve plate of the sealing washer between valve plate and the disk seat of present seal structure causes sealed degree to descend very easily.
SUMMERY OF THE UTILITY MODEL
In order to overcome the above-mentioned defect of prior art, the utility model provides a novel buggy is received whitewashed ware sealing device.
In order to achieve the above object, the utility model provides a following technical scheme: a novel sealing device of a pulverized coal collector comprises a shell, wherein an air cylinder is fixedly mounted at the upper part of the shell, a pull rod of the air cylinder penetrates through the shell, the top end of the pull rod sequentially penetrates through an outer layer valve plate and an inner layer valve plate, the top end of the pull rod is fixedly connected with the outer layer valve plate and the inner layer valve plate, sealing rings are arranged at the edges of the outer layer valve plate and the inner layer valve plate, an inner layer valve seat and an outer layer valve seat are fixedly mounted on the inner wall of the shell, and inserting grooves are formed in the outer side upper edges of the inner layer valve seat and the outer layer valve seat; when the valve is closed, the sealing ring of the outer valve plate is inserted into the slot of the outer valve seat and tightly attached, and the sealing ring of the inner valve plate is inserted into the slot of the inner valve seat and tightly attached.
The top end of the pull rod is fixedly installed with the outer-layer valve plate and the inner-layer valve plate through nuts, and the nuts are matched with the threads on the top of the pull rod.
The top of the pull rod is provided with a bolt which can prevent the nut from falling off.
And reinforcing pieces are arranged at the upper edges of the outer sides of the inner-layer valve seat and the outer-layer valve seat and used for stabilizing the inserting grooves.
The utility model discloses a technological effect and advantage: by adopting double-layer sealing, the sealing performance is improved, the stress at the sealing part is smaller and more uniform, the service life is prolonged, and meanwhile, the sealing degree in the service life of the sealing ring is ensured.
