Abstract
The utility model relates to a draught fan sealing device, which belongs to the matched components and parts in the technical field of ventilators. The utility model comprises a driving shaft of a draught fan, a shell body of the draught fan and a sealing body fixed on the shell body of the draught fan. The utility model is characterized in that a trapezoidal sealing ring installed at intervals and an inverted trapezoidal press ring matched with the sealing ring are arranged between the sealing body and the driving shaft of the draught fan; the inner diameter of the inverted trapezoidal press ring is larger than the inner diameter of the sealing ring; the end part of the sealing body is provided with an adjusting press cover which is tightly fixed on the end part; the inner end surface of the adjusting press cover contacts the side surface of the trapezoidal sealing ring or the inverted trapezoidal press ring. The utility model has the advantages that the sealing performance of the draught fan is obviously enhanced, and the environmental pollution caused by the leakage of harmful gases is avoided. The utility model can be used for conveying poisonous gases, such as coal gas, positive ethane gas, hydrochloric acid gas, etc., and can also be used for conveying the harmful gases with radioactivity of a nuclear power plant.
Description
Affiliated field
The utility model relates to a kind of fan sealing device, belongs to the auxiliary component in the ventilation equipment field.
Background technique
Along with the development of ventilator technology, its Applicable scope is regulated by original conveying innocuous gas or as indoor and outdoor air, has expanded the media poisonous to human body such as toxic gases such as carrying coal gas, hexane gas, hydrogen chloride gas, or even radioactive air to.This just requires the sealability of blower fan very good, otherwise gas leakage causes environmental pollution, is detrimental to health.But the sealing effect of the seal arrangement of existing blower fan is not very desirable.
Summary of the invention
In order to solve the shortcoming that above-mentioned prior art exists, the purpose of this utility model provides a kind of sealing effect ideal and seals adjustable fan sealing device.
The technical solution of the utility model is: this kind fan sealing device, and it comprises the blower fan transmission shaft, Blower Housing is installed on the blower fan transmission shaft and is fixed on seal on the Blower Housing; It is characterized in that: be provided with between seal and the blower fan transmission shaft the trapezoidal seal ring of installing at interval and match with it fall trapezoidal pressure ring, fall the internal diameter of trapezoidal pressure ring greater than the internal diameter of trapezoidal seal ring; The end of seal is provided with fastening one on it and regulates gland, regulates the interior edge face and the trapezoidal seal ring of gland or falls the contacts side surfaces of trapezoidal pressure ring.
For increasing the adjustment amount of regulating gland and increasing the sealability of regulating gland and seal end, described adjusting gland and seal end also are provided with the adjustment pad.
For improving the wear resistance of trapezoidal seal ring, the material of described trapezoidal seal ring is a graphite.
The described trapezoidal pressure ring, trapezoidal seal ring of falling is provided with a plurality of, the most inboard trapezoidal seal ring sides and seal inner side surface at interval and coincide and form sealing surface; Outermost trapezoidal seal ring side and adjusting gland contacts side surfaces are to increase radial pressure, and preferably bi-side coincide and the formation sealing surface.
The utility model use because the trapezoidal seal ring and the trapezoidal pressure ring that falls closely cooperate, in seal, be combined into labyrinth form sealing, add by being bolted to compressing of adjusting gland on the seal, integral sealing effect to the blower fan transmission shaft is very desirable, significantly improved the sealability of blower fan, avoided blower fan when running up, the leakage of hazardous medium, thus guaranteed Environmental security; Because the trapezoidal seal ring in the utility model and the trapezoidal pressure ring that falls adopt split type structure, have made things convenient for the replacing of the seal ring that lost efficacy, and have made things convenient for the maintenance of equipment, it and the supporting use of blower fan can be widely used in the conveying of chemical industry harmful gas.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is a structural representation of the present utility model,
Among the figure: 1 transmission shaft, 2 Blower Housings, 3 seals, 4 trapezoidal seal rings, 5 fall trapezoidal pressure ring, and 6 regulate glands, and 7 regulate bolts, 8 fixing bolts.
Embodiment
As shown in drawings, this fan sealing device, it comprises blower fan transmission shaft 1, Blower Housing 2 is installed on blower fan transmission shaft 1 and is fixed on seal 3 on the Blower Housing 2.Be provided with four trapezoidal seal rings 3 installing at interval and three of matching with trapezoidal seal ring 3 between seal 3 and the blower fan transmission shaft 1 and fall trapezoidal pressure ring 4, trapezoidal seal ring 3 is wherein made for graphite; Connect an adjusting gland 6 by regulating bolt 7 on the seal 3.Regulate the sealability that gland 6 can be regulated this device, also made things convenient for the trapezoidal seal ring 3 of corrupted or fallen the replacing of trapezoidal pressure ring 4, package unit is fixed on the Blower Housing 2 by fixing bolt 8.
Fall the internal diameter of trapezoidal pressure ring 5 greater than the internal diameter of trapezoidal seal ring 4, so that when regulating gland 6 increase sealings, make down trapezoidal pressure ring 5 produce a certain amount of moving radially, not only increased the axial force of falling between trapezoidal pressure ring 5 and the trapezoidal seal ring 4, the apex seal performance between trapezoidal seal ring 4 and the transmission shaft 1 also is improved simultaneously.
Claims (3)
1, a kind of fan sealing device, it comprises the blower fan transmission shaft, Blower Housing is installed on the blower fan transmission shaft and is fixed on seal on the Blower Housing; It is characterized in that: be provided with between seal and the blower fan transmission shaft the trapezoidal seal ring of installing at interval and match with it fall trapezoidal pressure ring, fall the internal diameter of trapezoidal pressure ring greater than the internal diameter of trapezoidal seal ring; The end of seal is provided with fastening one on it and regulates gland, regulates the interior edge face and the trapezoidal seal ring of gland or falls the contacts side surfaces of trapezoidal pressure ring.
