Abstract
The invention discloses a kind of noise-reducing structure of drying cylinder, comprise steam turbine, steam pipework, drying cylinder, described steam turbine is connected by steam pipework with drying cylinder, described steam pipework is connected to hydrophobic development unit muffler and steam pipework is enclosed with butyl rubber, steam releasing silencer steam pipework after drying cylinder is equipped with, set up hydrophobic development unit muffler between drying cylinder and steam pipework after, effectively decrease the generation of noise, steam pipework wraps up the generation that butyl rubber decreases noise on the one hand, and decrease heat and run off by heat radiation, more energy-conservation, using shock bracket to install fixed steam pipeline is also produce unnecessary noise to prevent from resonating, after adopting such noise-reducing structure, noise on papermaking streamline can control in harmless scope.
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
In paper industry, steam turbine both can be used as dynamic power, the steam produced is owing to being also used to containing amount of heat dry in the equipment of paper, such as drying cylinder, but it is very large at the noise of the situation tubine steam discharge of disconnected paper, it is not only steam turbine, all can produce larger noise in each link of the transmission of steam, and pipeline energy-conservation in also to have greatly improved space.
Summary of the invention
The technical issues that need to address of the present invention are, provide a kind of and effectively can reduce noise in drying cylinder use procedure 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 is connected by steam pipework with drying cylinder, described steam pipework be connected to hydrophobic development unit muffler and steam pipework is enclosed with butyl rubber, the steam pipework after drying cylinder being equipped with steam releasing silencer.
As preferably, described steam pipework shock bracket is installed fixing.
As preferably, described hydrophobic development unit muffler and fixed connection place, ground are provided with elastic caoutchouc shock insulation seat.
As preferably, described steam pipework is equipped with safety valve, and safety valve is provided with muffler.
As preferably, described butyl rubber is wrapped with asbestos ring, has stainless steel protective cover at asbestos ring overcoat.
After adopting technique scheme, tool of the present invention has the following advantages:
Set up hydrophobic development unit muffler between drying cylinder and steam pipework after, effectively decrease the generation of noise, steam pipework wraps up the generation that butyl rubber decreases noise on the one hand, and decrease heat and run off by heat radiation, more energy-conservation, using shock bracket to install fixed steam pipeline is also produce unnecessary noise to prevent from resonating, and after adopting such noise-reducing structure, the noise on papermaking streamline can control in harmless scope.
Accompanying drawing explanation
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 sectional view of the steam pipework of the noise-reducing structure of drying cylinder of the present invention.
Shown in 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, hydrophobic development unit muffler, 6, butyl rubber, 7, steam releasing silencer, 8, elastic caoutchouc shock insulation seat.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further:
As Fig. 1, shown in Fig. 2, the drying cylinder noise-reducing structure of the present embodiment comprises steam turbine 1, steam turbine 1 is connected with steam releasing silencer 7 order that is connected with drying cylinder 3 by steam pipework 2, steam pipework 2 is installed on ground by shock bracket 22 or other are in order on fixing supporter, steam pipework 2 is enclosed with butyl rubber 6, butyl rubber 6 is wrapped with asbestos ring 4, asbestos ring 4 is wrapped with stainless steel protective cover 40, due to butyl rubber 6, asbestos ring 4 possesses good in heat-resistant quality of making an uproar, steam-energy keeps the condition of high temperature, and stainless steel protective cover 40 is to prevent external environment condition 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, safety valve 20 is provided with muffler 21 to reduce herein due to the noise of air-flow convolution generation.Steam pipework 2 is then connected with a hydrophobic development unit muffler 5, and hydrophobic development unit muffler 5 and fixed connection place, ground are provided with elastic caoutchouc shock insulation seat 8, and to prevent because the air-flow in hydrophobic development unit muffler 5 is unstable, generation is vibrated.Enter in drying cylinder 3 via the steam after hydrophobic development unit muffler 5 processes with steam pipework 2, drying cylinder 3 utilizes the heat of steam to be dried by paper, and steam is also lowered the temperature condensation, then enters in steam releasing silencer 7 with steam pipework 2 and cool the water that is in a liquid state further.
Below only just the present invention preferably example be described, 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 change and distortion according to the present invention, only otherwise depart from spirit of the present invention, all should belong to the scope that claims of the present invention define.
