Abstract
The utility model discloses a sealing device for a fluorine hydride rotary furnace burner and a furnace tail and belongs to the technical field of rotary furnaces. The sealing device for the fluorine hydride rotary furnace burner and the furnace tail comprises a dynamic sealing ring (3), a static sealing ring (4), a corrugated pipe (6), an air cylinder (5) and a bracket (7), wherein the dynamic sealing ring (3) is arranged outside an end cover (2) of a furnace body (1), the static sealing ring (4) is fixedly connected with the corrugated pipe (6), the corrugated pipe (6) is connected with a discharging device (8), one end of the air cylinder (5) is connected with the static sealing ring (4), the other end of the air cylinder (5) is connected with the bracket (7), the dynamic sealing ring (3) is tightly attached to the static sealing ring (4), the discharging device is arranged on the bracket (7), and the bracket (7) is fixed on the ground. The sealing device for the fluorine hydride rotary furnace burner and the furnace tail has the advantages that a dynamic-static sealing ring mode is adopted, the sealing performance is improved, and the discharging device does not need to rotate.
Description
Technical field
The utility model relates to a kind of sealing device, and specifically a kind of hydrogen fluoride rotary furnace burner stove tail sealing device, belong to the rotary furnace technical field.
Background technology
The hydrogen fluoride rotary furnace is the equipment of producing hydrogen fluoride necessity, body of heater can rotate and remain on a higher temperature value when producing, because hydrogen fluoride has severe toxicity, so sealing must be secure when carrying out the charging discharging, early stage chemical furnace is sealed with plunger type, labyrinth sealing, weak effect, fault is more, has a small amount of gas leak phenomenon.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model provides a kind of hydrogen fluoride rotary furnace burner stove tail sealing device, adopts the mode of static and dynamic sealing ring, improve sealing, and drawing mechanism need not to rotate.
To achieve these goals, the technical solution adopted in the utility model is: a kind of hydrogen fluoride rotary furnace burner stove tail sealing device, comprise rotary packing ring, stationary seal ring, bellows, cylinder and support, rotary packing ring is arranged on the end cap outside of body of heater, stationary seal ring is fixedly connected with bellows, bellows is connected with drawing mechanism, one end of cylinder is connected with stationary seal ring, the other end of cylinder is connected with support, rotary packing ring and stationary seal ring fit tightly, drawing mechanism is arranged on support, and support fixes on the ground.
The beneficial effects of the utility model are: simple to operate, easy to use, and the mode that adopts rotary packing ring and stationary seal ring to combine, the sealing when having improved burner stove tail discharging charging, and make drawing mechanism need not to rotate.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model course of work schematic diagram.
In figure: 1, body of heater, 2, end cap, 3, rotary packing ring, 4, stationary seal ring, 5, cylinder, 6, bellows, 7, support, 8, drawing mechanism.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of hydrogen fluoride rotary furnace burner stove tail sealing device, comprise rotary packing ring 3, stationary seal ring 4, bellows 6, cylinder 5 and support 7, rotary packing ring 3 is arranged on end cap 2 outsides of body of heater 1, and stationary seal ring 4 is fixedly connected with bellows 6, bellows 6 is connected with drawing mechanism 8, one end of cylinder 5 is connected with stationary seal ring 4, and the other end of cylinder 5 is connected with support 7, and rotary packing ring 3 and stationary seal ring 4 fit tightly, drawing mechanism is arranged on support 7, and support 7 fixes on the ground
As shown in Figure 2, during use, stretching routine by cylinder 5 fits tightly rotary packing ring 3 and stationary seal ring 4, because dynamic and static sealing ring all adopts precise machining process, when rotary packing ring 3 rotates, almost very close to each other between rotary packing ring 3 under the cylinder pressure effect and stationary seal ring 4, have fabulous sealing between rotary packing ring 3 and stationary seal ring 4.
Above-mentioned rotary packing ring 3 and this sealing device of stationary seal ring 4 are equally applicable to the sealing between burner and feed arrangement.
