Description
Technical field
The invention belongs to field of thermal power, particularly to a kind of heat power plant boiler dust pelletizing system Pneumatic gate valve.
Background technology
In thermal power generation corporations, boiler is one of necessary equipment in production process, with people to environmental protection
Require raising it will usually in boiler plant additional cleaner, its operation principle is using electrostatic or whirlwind or mistake
The dust that boiler combustion fuel produces is collected and is focused on by the methods such as filter；In existing dust pelletizing system, through the ash collected
Dirt, is admitted to dust collecting duct, by dust collecting duct, by dust centralized collection to dust compartment；Between dust collecting duct to dust compartment,
Often a valve is set, because the collection of dust is to need a process, without valve, dust can be always to dust
Storehouse conveys, and causes new airborne dust；Existing valve adopts pneumatic control mostly, if operated pneumatic valve failure or unknown its are opened
State, just cannot know whether dust leg is in the state of being turned on or off, valve closing is not opened, dust can be in dust leg
Cumulative, cause line clogging even to damage, valve opening can not be closed, result in new airborne dust, pollute environment.
Content of the invention
Open and close what state was difficult to monitor for the operated pneumatic valve in existing heat power plant boiler dust pelletizing system
Situation, the present invention propose a kind of heat power plant boiler dust pelletizing system Pneumatic gate valve it is characterised in that: include dust leg, valve plate,
Framework, cylinder, sensor；Described dust leg is arranged on the front end of dust compartment in boiler dust removal system, connects with dust compartment；Institute
The valve plate stated is arranged on the middle part of dust leg, can realize opening and closing along the cross-sectional direction of dust leg is mobile, close
Dust leg can be isolated into two spaces when closing and be not communicated with, the unimpeded of dust leg when opening, can be recovered；Described framework
It is arranged on the dust leg of valve plate position, valve plate can move along a straight line along framework；Described cylinder is arranged on framework, with frame
Frame is fixedly connected, and its piston rod is connected with valve plate, and valve plate can move with the motion of piston rod；Described sensor is arranged on
On framework；Described sensor has more than one；Position on framework for the described sensor and the opening and closing row of valve plate
Journey matches, and can detect the opening and closing position of valve plate；Described sensor is photoelectric sensor or close to opening
Close or mechanical trip switch.
Beneficial effect
The beneficial effects of the present invention is, the opening and closing shape that boiler dust removal system starts gate valve can be monitored at any time
State, is easy to operating personnel and takes appropriate measures, and reduces the generation of production accident.
Fig. 1 is the welding structure schematic diagram of the present invention
1. dust leg, 2. valve plate, 3. framework, 4. cylinder, 5. sensor.
Specific embodiment
In order to further illustrate technical scheme, in conjunction with the specific embodiment of the brief description present invention；As
Fig. 1, in this example taking the Pneumatic gate valve structure that the industry is commonly used as a example, from 400 millimeters of the cross-sectional width of dust leg 1, section is long
600 millimeters of degree；It is 10 millimeters from thickness, 700 millimeters of length, the steel plate that 400 millimeters of width is as valve plate 2；High from section
60 millimeters of degree, the rectangular steel pipe that 40 millimeters of cross-sectional width is simultaneously welded to the both sides of dust leg 1 as framework 3；From commercially available
800 millimeters of 50 millimeters of strokes of cylinder diameter cylinder as cylinder 4, and be installed in frame afterbody, by the tail of piston rod and valve plate 2
End is hinged；Switched as sensor 5 from the general mechanical trip of the commercially available industry, in this example, select two sensors 5, point
It is not arranged on framework 3 and be located at valve plate 2 unlatching maximum position and closed position, and the control by sensor 5 and boiler dust removal system
System processed connects；This completes the enforcement of the present invention；During application, when the piston rod of cylinder 4 stretches out, drive valve plate 2 forward
Motion, so that valve plate 2 enters the cross-sectional internal of dust leg 1, the channel separation of dust leg 1 enters the closed mode of valve plate 2,
The sensor 5 installing on the frame 3 and being located at valve plate 2 closed position is opened, and issues a signal to the control system of boiler dust removal system
System, shows that in this control system valve plate 2 is closed；Conversely, when the piston rod of cylinder 4 withdraws, driving valve plate 2 backward
Motion, valve plate 2 is disengaged with the section of dust leg 1, touches and is arranged on the sensor 5 being located at valve plate 2 open position on framework 3, passes
Sensor 5 issues a signal to the control system of boiler dust removal system, shows that valve plate 2 is in opening, thus within the system
It is easy to the opening and closing state that operating personnel monitor the Pneumatic gate valve of boiler dust removal system in time, it is to avoid unnecessary airborne dust and damage
Bad dust leg 1 and relevant device are normally carried out it is ensured that producing.
