Abstract
The invention discloses a multi-degree-of-freedom moving sealing device, and relates to the sealing of a core part mechanical grate boiler in large-sized waste incineration equipment. The sealing device comprises a sealing core, a sealing core sleeve, an L-shaped iron component and a base plate, wherein the sealing core is in cylindrical surface contact and plane contact with the sealing core sleeve; a steel pipe is arranged in the sealing core; the sealing core is in sealed connection with the steel pipe through a graphite packing. According to the sealing device, the sealing core, the sealing core sleeve, the base plate and the L-shaped component are matched to realize sealing; the steel pipe is arranged in the sealing core, high sealing performance between the sealing core and the steel pipe and between the sealing core and the sealing core sleeve is ensured, the sealing core and the steel pipe can slide relative to each other, and the sealing core and the sealing core sleeve can rotate relative to each other; the sealing device is reasonable in structure, simple and practical.
Description
Technical field
The present invention relates to the sealing of the core component mechanical kiln grate furnace in the bulky refuse incinerator, specifically a kind of seal arrangement of multifreedom motion.
Technical background
Continuous progress along with society, economic sustainable development and the raising day by day of living standard, city and rural refuse production sharply increase, waste incineration and generating electricity has been realized focusing on of domestic waste, waste treatment facility standardization, standardization, improve human settlement's quality, and the main parts of garbage incinerating system are the mechanical kiln grate furnaces.If the drive unit of moving fire grate segment must be positioned over the outside of grate furnace casing, drive unit is connected with grate furnace by connecting rod, and the motion of connecting rod is again multivariant compound motion.And the grate furnace body needs sealing, now just need the seal arrangement that can make multifreedom motion.
Summary of the invention
Technical problem to be solved by this invention is in the motion of a plurality of degrees of freedom directions, can keep seal request again.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of seal arrangement of multifreedom motion, comprise sealed core, sealing core retainer plate, L shaped iron component, substrate, it is characterized in that, described sealed core and sealing core retainer plate Cylindrical Surfaces Contact and plane contact, the in-built steel pipe of described sealed core, be tightly connected by the graphite packing between described sealed core and steel pipe.
Described sealed core and steel pipe adopt end cap by the graphite packing_seal.
Between described sealed core and sealing core retainer plate, plane contact partly is provided with the packing liftout attachment, and described packing liftout attachment ejects the graphite packing.
Described sealed core puts oil groove is set, and fills molybdenum disulphide grease in described oil groove.
In described L shaped iron component, spring and steel ball are housed, described spring withstands steel ball, and steel ball is pushed down the sealing core retainer plate.
Have draw-in groove in described substrate, the graphite plate root is housed in described draw-in groove.
Beneficial effect of the present invention: seal arrangement of the present invention is realized sealing by the cooperation of sealed core, sealing core retainer plate, substrate and L shaped assembly, steel pipe is housed in sealed core, good airproof performance between sealed core and steel pipe, sealed core and sealing core retainer plate, but relative sliding between sealed core and steel pipe, can relatively rotate between sealed core and sealing core retainer plate.The present invention is rational in infrastructure, simple and practical.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
As shown in Figure 1, a kind of seal arrangement of multifreedom motion, comprise sealed core 1, sealing core retainer plate 2, L shaped iron component 3, substrate 4, sealed core 1 and sealing core retainer plate 2 Cylindrical Surfaces Contacts and plane contact, the in-built steel pipe 5 of sealed core 1, be tightly connected by graphite packing 7 between sealed core 1 and steel pipe 5.
As shown in Figure 2, sealed core 1 and steel pipe 5 adopt end cap 6 by 7 sealings of graphite packing.Graphite packing 7 smooth surfaces, can make again relative sliding between sealed core 1 and steel pipe 5.
As shown in Figure 3, between sealed core 1 and sealing core retainer plate 2, plane contact partly is provided with packing liftout attachment 8, and packing liftout attachment 8 ejects graphite packing 7, for guaranteeing sealing, the Multi-layer graphite packing can be set.
As shown in Figure 4, oil groove 9 is set, the interior filling molybdenum disulphide grease of oil groove 9, the outer installation oil seal cover 10 of oil groove 9 on sealing core retainer plate 2.Regularly or when needed can back out oil seal cover 10, to the interior interpolation lubricating grease of oil groove 9.
As shown in Figure 5, spring 11 and steel ball 12 are housed in L shaped iron component 3, described spring 11 withstands steel ball 12, and steel ball 12 is pushed down sealing core retainer plate 2.Do the motion of left and right directions in the groove that the assembly that sealed core 1 and sealing core retainer plate 2 form can form between L shaped iron component 3 and substrate 4, the gap of above-below direction is set, realize swinging up and down.
As shown in Figure 6, have draw-in groove 13 in substrate 4, the graphite plate root is housed in draw-in groove 13.Sealing core retainer plate 2 tightly suppresses the graphite packing, realizes the sealing between surface of contact.
