Abstract
The utility model discloses a rotary drying machine, comprising a rotary barrel, an air supply pipeline and an exhaust pipeline which are sleeved together coaxially. The rotary barrel is provided with an air inlet and an air outlet; the air inlet and the air outlet are communicated with an air inlet device and an air outlet device respectively; one end of a heat supply pipeline is communicated with the air inlet device; one end of the exhaust pipeline is communicated with the air outlet device; one end of heat supply pipeline and one end of the exhaust pipeline are provided with static seal discs; the air inlet and the air outlet of the rotary barrel are provided with dynamic seal discs adaptive to the static seal discs; and packing made of soft high-abrasive material is disposed between the static seal discs and the dynamic seal discs. The graphite packing is disposed between the static seal discs and the dynamic seal discs and the dynamic seal discs are fixed on the rotary barrel, so the sealing property of the rotary drying machine is improved and the negative pressure bearing capacity of the rotary drying machine during work is improved.
Description
Technical field
The utility model relates to a kind of rotary dryer.
Background technology
At present, rotary dryer is a material heat drying device, make in the cylindrical shell material through turn back, operation such as lifting, with drying materials.But rotary dryer in the course of the work; Because it is bulky, has caused various piece to have the bigger temperature difference, thereby caused that cylindrical shell and each connector expand; Especially the junction of cylindrical shell and air inlet, air outlet is very easy to occur damaging, and causes poorly sealed.Because cylindrical shell rotates; And air inlet, air outlet adopt static mode, in order to improve its sealing, generally adopt the labyrinth sealing mode; But its sealing sealing negative pressure is less; Can only applying micro-negative-pressure or atmospheric pressure state, inconvenience is brought to the user in the application space of having limited rotary dryer.
This shows that prior art needs further improvement and develops.
The utility model content
The utility model provides a kind of rotary dryer for solving defective of the prior art; Rotary dryer of the prior art is carried out scientific and reasonable improvement; To improve the sealing property of rotary dryer, the negative pressure ability to bear when improving rotary dryer work.
For solving the problems of the technologies described above, the utility model scheme comprises:
A kind of rotary dryer, it comprises rotating cylinder, supply air line and gas exhaust piping with axle sleeve row, wherein, this rotating cylinder is provided with air inlet and air outlet, air inlet and air outlet respectively with air-intake device with go out wind apparatus and be connected; One end of heat supplying pipeline is connected with air-intake device; One end of gas exhaust piping with go out wind apparatus and be connected; Be respectively arranged with the static seal dish on one end of this heat supplying pipeline and the end of gas exhaust piping; Be respectively arranged with the movable sealing dish suitable on rotating cylinder air inlet, the air outlet, be provided with the packing of processing by soft high-abrasive material between static seal dish and the movable sealing dish with the static seal dish.
Described rotary dryer, wherein, above-mentioned packing is the graphite packing
Described rotary dryer wherein, is provided with the helical blade that is used for lifting and is interrupted the spiral lifting blade in the above-mentioned rotating cylinder.
A kind of rotary dryer that the utility model provides is provided with the graphite packing between static seal dish and movable sealing dish, the movable sealing dish is fixed on air inlet and the air outlet on the rotating cylinder; It rotates with respect to the static seal dish, and the graphite packing has played the effect of dynamic seal (packing), and its volume is less; Significantly reduced consumptive material; And its structural volume be the labyrinth sealing mode 1/3 once, its leakage rate is almost nil in running, makes rotary dryer work negative pressure reach 3000KPa; Improved the sealing property of rotary dryer, the negative pressure ability to bear when having improved rotary dryer work.
Description of drawings
Fig. 1 is the section signal sketch drawing of the hermetically-sealed construction of the utility model middle cylinder body.
The specific embodiment
The utility model provides a kind of rotary dryer, for purpose, technical scheme and the advantage that makes the utility model is clearer, clear and definite, below will combine accompanying drawing and embodiment, to the utility model further explain.
The utility model provides a kind of rotary dryer; Be employed in the Mechanical Contact sealing means that the graphite packing is set between the dynamic and static seal disc; Substitute labyrinth sealing mode in the prior art; Improved the sealing property of rotary dryer, the negative pressure ability to bear when having improved rotary dryer work has been expanded its application space.As shown in Figure 1, rotary dryer comprises that this rotating cylinder 1 can adopt technology type well known in the prior art with rotating cylinder 1, heat supplying pipeline and the gas exhaust piping of axle sleeve row.
This rotating cylinder 1 is provided with air inlet and air outlet, and is as shown in Figure 1 for convenience, is that example describes with the air inlet on the swinging cylindrical shell 12 only.Air inlet 2 and air outlet respectively with air-intake device with go out wind apparatus and be connected; One end of heat supplying pipeline is connected with air-intake device; One end of gas exhaust piping with go out wind apparatus and be connected; Be respectively arranged with static seal dish 3 on one end of this heat supplying pipeline and the end of gas exhaust piping; Be respectively arranged with the movable sealing dish 4 suitable on the air inlet 2 of rotating cylinder 1, the air outlet, be provided with the packing of processing by soft high-abrasive material 5 between static seal dish 3 and the movable sealing dish 4, the packing of processing such as graphite packing, tetrafluoroethene packing or other soft high-abrasive materials with static seal dish 3.
In order further to improve the performance of the utility model, be provided with the helical blade that is used for lifting in the rotating cylinder 1 and be interrupted the spiral lifting blade, can certainly adopt other forms of lifting mechanism in the prior art.And heat dissipation pipeline comprises a plurality of internal flues, a plurality of annular flue gas pipe and a plurality of radially smoke pipe, all is connected through corresponding radially smoke pipe between the internal flue, between the annular flue gas pipe and between internal flue and the annular flue gas pipe.
Certainly; Above-mentioned explanation is not to be the restriction to the utility model; The utility model also be not limited in above-mentioned for example, variation, remodeling, interpolation or replacement that the technical staff in present technique field is made in the essential scope of the utility model also should belong to the protection domain of the utility model.
