Abstract
The invention discloses a combined modularly-designed shaft seal for a reaction kettle, used for a dynamic seal at a stirring shaft of chemical equipment such as the reaction kettle and the like and particularly suitable for high-temperature and high-pressure shaft dynamic seal occasions with solid particles. A main implementation scheme for the invention is as follows: four sealing modules are arranged, a part from the interior to the exterior of the reaction kettle comprises the following layers: 1, a sealing module with a rubber seal ring as a main frame; 2, a sealing module with a copper-aluminum composite shaft sleeve; and 3, a sealing module with graphite-asbestos composite fillers as a main frame, and several sealing manners are combined to achieve a high-efficiency sealing effect; meanwhile, because the shaft seal is of a modular design in structure, the shaft seal can be extremely convenient to dismount and replace during maintenance.
Description
Technical field:
A kind of composite module design reaction kettle is used shaft sealing, is used for stirring shaft place motive sealings such as chemical industry equipment reaction kettle, and the axle that is particularly useful for high temperature, high pressure and has a solid particulate matter is used the motive sealing occasion.
Background technique:
In the chemical reaction process, can often need use motive sealing, like the motive sealing of reaction kettle stirring shaft main shaft; The motive sealing of environmental protection equipment valve main shaft under the situation of, high pressure high temperature resistant at needs, is often adopted mechanical seal; But traditional mechanical seal cost is high, and is complicated through structure, and if have solid particulate matter in the reaction mass; And if consersion unit must be horizontally-arranged, the material that has solid particle directly contacts with mechanical seal, and solid particle infiltrates the mechanical seal inner space; Under high speed conditions, the mechanical seal destruction that will soon be worn.
Summary of the invention:
The axle that a kind of cost is low in order to provide, the reliable high temperature high voltage resistant of sealability and solid particulate matter impact is used the motive sealing system; On the gland sealed basis; A kind of composite module design reaction kettle of special proposition is used axle sealing system; Its main implementation is such: seal modules at first is set, extremely has with lower floor outward in the autoreaction still: 1, be the seal modules of body frame with the rubber seal; 2, be the seal modules of body frame with copper aluminium composite shaft sleeve; 3, be the seal modules of body frame with graphite asbestos composite filling.
Wherein, said is the seal modules of body frame with the rubber seal, is made up of rubber seal and holddown spring, and said rubber seal is " O " shape rubber seal, is compressed by holddown spring, makes it to fit on the main shaft to be sealed.
Said copper aluminium composite shaft sleeve is the seal modules of body frame, is made up of copper aluminium compound seal axle sleeve outsourcing fixed cover and bolt, and copper aluminium compound seal axle sleeve is fixed in the outsourcing fixed cover, is placed on the reaction kettle main shaft; Outsourcing fixed cover periphery is opened the screw thread fixed hole; The reaction kettle housing also leaves the screw thread fixed hole; Outsourcing set casing screw thread fixed hole is corresponding with reaction kettle housing screw thread fixed hole, and seal modules is connected and fixed on the reaction kettle housing by bolt through the tapped hole of outsourcing fixed tray.
Said is to establish stuffing box packing in the seal modules of body frame with graphite asbestos composite filling; Stuffing box packing outsourcing fixed cover, said stuffing box packing is processed thread by graphite and asbestos, be mixed into filling block or filler bar; Wrap by the sealing of establishing in fixed cover edge cover and to be compacted on the reaction kettle main shaft; Outsourcing fixed cover periphery is established fixing threaded hole, and seal modules is connected on the previous stage seal modules by bolt through fixing threaded hole, and said seal modules can be provided with the cooling liquid body cavity between filler and outer fixing cover.
The present invention is when work, because fluorine rubber is high temperature resistant, wear-resistant; Viton seal ring can be with the solid particulate matter obstruction seals, and the further obstruction seals of solid particulate matter that copper aluminium composite shaft sleeve is come seepage prevents that it from damaging the graphite packing sealing; Material steam and heat that the graphite packing sealing then goes out the first two road seal leak further seal; Several sealing means have been combined to form sealing effect efficiently, and are simultaneously because this structure is modular design, very convenient during dismounting and change when maintenance.
Description of drawings:
Fig. 1 is the whole cross-sectional view of the present invention;
Fig. 2 be according to the invention be the seal modules sectional drawing of body frame with the rubber seal;
Fig. 3 is a mounting structure schematic representation of the present invention;
Wherein: (1) rubber seal, (2) holddown spring, (3) outsourcing fixed cover, (4) screw thread fixed hole; (5) bolt, (6) copper aluminium compound seal axle sleeve, (7) reaction kettle housing; (8) stuffing box packing, (9) sealing edge cover, (10) cooling liquid body cavity; (11) with the rubber seal be the seal modules of body frame, (12) are the seal modules of body frame with copper aluminium composite shaft sleeve, and (13) are seal modules (14) main shaft of body frame with graphite asbestos composite filling.
Embodiment:
Shown in Fig. 1/2, seal modules at first is set, by the reaction kettle housing, around main shaft have from the inside to the outside following which floor: 1, with the rubber seal be the seal modules (11) of body frame; 2, with copper aluminium composite shaft sleeve be the seal modules (12) of body frame; 3, with graphite asbestos composite filling be the seal modules (13) of body frame.
Wherein, said is the seal modules (11) of body frame with the rubber seal, is made up of rubber seal (1) and holddown spring, and said rubber seal (1) is " O " shape rubber ring, is compressed by holddown spring (2), makes it to fit in (14) on the main shaft to be sealed.
The seal modules (12) that said copper aluminium composite shaft sleeve is a body frame is made up of copper aluminium compound seal axle sleeve (6) outsourcing fixed cover (3) and bolt, and copper aluminium compound seal axle sleeve (6) is fixed in the outsourcing fixed cover (3), fits to be located on the reaction kettle main shaft (14); Outsourcing fixed cover (3) periphery is opened screw thread fixed hole (4); Reaction kettle housing (7) also leaves screw thread fixed hole (4); The screw thread fixed hole of establishing on the outsourcing set casing (3) (4) is corresponding with reaction kettle housing (7) screw thread fixed hole (4), and seal modules is connected and fixed on the reaction kettle housing (7) by bolt (5) through the tapped hole (4) of outsourcing fixed tray (3).
Said is to establish stuffing box packing (8) in the seal modules (13) of body frame with graphite asbestos composite filling; Stuffing box packing (8) is located in the outsourcing fixed cover (3); Said stuffing box packing (8) is processed thread by graphite and asbestos; Be mixed into filling block or filler bar, wrapped by the sealing of establishing in the fixed cover (3) edge cover and be compacted on the reaction kettle main shaft (14), outsourcing fixed cover (3) periphery is established fixing threaded hole; Seal modules is connected on the previous stage seal modules by bolt (5) through fixing threaded hole (4), and said seal modules can be provided with cooling liquid body cavity (10) between filler (8) and outer fixing cover (3).
