Abstract
The invention discloses a silencing structure of a drying cylinder, comprising a steam turbine, a steam pipeline and a drying cylinder, wherein the steam turbine is connected with the drying cylinder through the steam pipeline, the steam pipeline is connected with a drain water expander muffler, the steam pipeline is wrapped by butyl rubber, a steam diffusing muffler is mounted on the steam pipeline behind the drying cylinder, after the drain water expander muffler is additionally arranged between the drying cylinder and the steam pipeline, the generation of noise is effectively reduced, the steam pipeline is wrapped by the butyl rubber, on one hand, the generation of noise is reduced, on the other hand, the heat is prevented from losing in the form of thermal radiation, the silencing structure is more energy-saving, and as the steam pipeline is fixedly mounted by a damping support, unnecessary noise generated by resonance is prevented. With the adoption of the silencing structure, the noise of a papermaking production line is controlled in the harmless range.
Description
Technical field
The present invention relates to a kind of noise-reducing structure of field of papermaking, what be specifically related to is a kind of noise-reducing structure of drying cylinder.
Background technology
Steam turbine both can be used as dynamic power in paper industry, the steam that produces also is used to dry in the equipment of paper owing to containing a large amount of heats, such as drying cylinder, but the noise at the situation tubine steam discharge of disconnected paper is very big, it is not only steam turbine, each link of transmission at steam all can produce bigger noise, and the space that also has greatly improved aspect pipeline energy-conservation.
Summary of the invention
The technical issues that need to address of the present invention are, provide a kind of and can effectively reduce noise in the drying cylinder use and the noise-reducing structure of energy-conserving and environment-protective.
Technical scheme of the present invention is: a kind of noise-reducing structure of drying cylinder, comprise steam turbine, steam pipework, drying cylinder, described steam turbine links to each other by steam pipework with drying cylinder, be connected on the described steam pipework on dewatering capacity-enlarging device muffler and the steam pipework and be enclosed with butyl rubber, on the steam pipework behind the drying cylinder steam is housed and diffuses silencer.
As preferably, described steam pipework installs and fixes with shock bracket.
As preferably, described dewatering capacity-enlarging device muffler and fixed connection place, ground are provided with elastic caoutchouc shock insulation seat.
As preferably, on the described steam pipework safety valve is housed, safety valve is provided with muffler.
As preferably, described butyl rubber is wrapped with asbestos ring, is with stainless steel protective cover outside asbestos ring.
After adopting technique scheme, the present invention has following advantage:
Between drying cylinder and steam pipework, set up after the dewatering capacity-enlarging device muffler, effectively reduced the generation of noise, reduced the generation of noise on the one hand at steam pipework parcel butyl rubber, and reduced heat and run off by heat radiation, more energy-conservation, using shock bracket to install and fix steam pipework also is in order to prevent that resonance from producing unnecessary noise, adopt such noise-reducing structure after, the noise on the papermaking streamline can be controlled in harmless scope.
Description of drawings
Accompanying drawing 1 is the layout schematic diagram of the noise-reducing structure of drying cylinder of the present invention;
Accompanying drawing 2 is the cutaway view of the steam pipework of the noise-reducing structure of drying cylinder of the present invention.
Shown in the figure, 1, steam turbine, 2, steam pipework, 20, safety valve, 21, muffler, 22, shock bracket, 3, drying cylinder, 4, asbestos ring, 40, stainless steel protective cover, 5, dewatering capacity-enlarging device muffler, 6, butyl rubber, 7, steam diffuses silencer, 8, elastic caoutchouc shock insulation seat.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further:
As Fig. 1, shown in Figure 2, the drying cylinder noise-reducing structure of present embodiment comprises steam turbine 1, steam turbine 1 diffuses silencer 7 orders by steam pipework 2 and drying cylinder 3 and the steam that links to each other and links to each other, steam pipework 2 usefulness shock bracket 22 are installed on ground or other are in order on the fixing supporter, be enclosed with butyl rubber 6 on the steam pipework 2, butyl rubber 6 is wrapped with asbestos ring 4, asbestos ring 4 is wrapped with stainless steel protective cover 40, because butyl rubber 6, asbestos ring 4 possesses good in the heat-resistant quality of making an uproar, steam can keep the condition of high temperature, and stainless steel protective cover 40 is in order to prevent that external environment condition is to the corrosion of steam pipework 2.Steam pipework 2 before dewatering capacity-enlarging muffler 5 is provided with safety valve 20, and safety valve 20 is used for controlling steam flow and pressure alarm, is provided with the noise of muffler 21 to reduce to circle round and produce owing to air-flow herein at safety valve 20.Steam pipework 2 then links to each other with a dewatering capacity-enlarging device muffler 5, and dewatering capacity-enlarging device muffler 5 is provided with elastic caoutchouc shock insulation seat 9 with the fixed connection place, ground, to prevent owing to the instability of the air-flow in the dewatering capacity-enlarging device muffler 5 produces vibration.Enter in the drying cylinder 3 with steam pipework 2 via the steam after 5 processing of dewatering capacity-enlarging device muffler, drying cylinder 3 utilizes the heat of steam that paper is dried, and steam is also lowered the temperature and condensed, and enters steam with steam pipework 2 again and diffuses the further water that is in a liquid state that cools off in the silencer 7.
Below only be described with regard to the preferable example of the present invention, but can not be interpreted as it is limitations on claims.The present invention not only limits to and above example, and its concrete structure those skilled in the art that allow to change can make various changes and distortion according to the present invention, only otherwise break away from spirit of the present invention, all should belong to the defined scope of claims of the present invention.
