Abstract
The utility model provides a pulse dust remover offline opening/closing device capable of maintaining an original state in a gas stopping process, belongs to the technical field of a dust remover, and aims to solve the problem of forming an accident in case that an air blower of the existing pulse dust remover offline opening/closing device is provided with an interlocking device. The pulse dust remover offline opening/closing device is characterized in that an air cylinder is connected with a connecting rod to convert retraction movement into rotation of a valve shaft, so that opening/closing movement of a valve plate is formed, and the dust remover works normally when the valve plate is opened; if gas is stopped and power is off, the air cylinder does not work; and the valve plate is not influenced by gravity and still keeps the previous opening state, so that the dust remover works normally. Air output resistance of the dust remover can be reduced so that the pulse dust remover offline opening/closing device is suitable for various types of pulse dust removers.
Description
Technical field
The utility model belongs to a kind of pulse dust collector off-line opening and closing device in the deduster technical field.
Background technique
Manufacture in the technology at present deduster, the off-line valve of off-line ash-clearing pulsed jet cloth filter is the round valve plate off-line of Pneumatic lifting type valve, because cylinder needs to adopt high-pressure air source as power in the work shape, and in case compressed gas source stops or cutting off the power supply after, under the deadweight and blower negative pressure pumping action of valve plate, the off-line valve cuts out thereby the off-line valve plate naturally droops; If this moment, blower fan did not arrange interlock, under the negative pressure of blower fan, easily cause the damage of deduster, the formation accident; If blower fan arranges interlock, thereby blower fan is quit work at this moment automatically, cause and normally to gather dust, the formation accident.
Summary of the invention
In order to overcome the deficiencies in the prior art, if solve existing pulse dust collector off-line opening and closing device blower fan interlock is set, with regard to the problem of formation accident.The purpose of this utility model is the worn-out end that changes original lifting type off-line valve; change the working state of off-line valve; avoid owing to stop the supple of gas or steam or accident that the off-line valve that causes of cutting off the power supply cuts out produces; guarantee that deduster can continue to keep original working state in the situation of stopping the supple of gas or steam temporarily or cutting off the power supply, protection deduster and the impregnable new-type pulse dust collector off-line opening and closing device of blower fan.
A kind of pulse dust collector off-line opening and closing device of attitude of remaining stationary of stopping the supple of gas or steam, it is to connect connecting rod by cylinder, and fore and aft motion is converted to the rotation of valve shaft, thereby makes valve plate form on-off action, deduster normal operation when valve plate is opened; If stop the supple of gas or steam, cut off the power supply, cylinder does not move, valve plate is not affected by gravity and still keeps original open mode, guarantees the deduster normal operation.
The technical problem that the utility model mainly solves is: the pneumatic power lifting valve of original form stop the supple of gas or steam or powering-off state under, valve plate autoshutdown cause damage of equipment or shut down that impact is normal to be used.Poppet valve is in the situation that guarantees air output, and occupation area is larger, and the deduster width is strengthened.Poppet valve reduces, and then improves wind speed, increases wind resistance.
The described laterally opened off-line valve of the utility model, the width spaces that can take full advantage of the deduster locellus arranges, and can effectively reduce the area that lifting type off-line valve takies.Reduce the wind resistance that of deduster.
The advantage of laterally opened off-line valve maximum is that the piston type with former cylinder moves through the rotation that connecting rod is converted to valve shaft, thereby drives the switching of valve plate.Required cylinder thrust was reduced, made again in case in the situation of stopping the supple of gas or steam, valve plate is not subjected to the impact of gravity and negative pressure, maintained the original state, guaranteed the normal operation of deduster.Cylinder thrust reduces, and the cylinder specification is reduced, and stroke shortens and reduces cost.Laterally opened off-line has been avoided former poppet valve cylinder column and the situation that flue gas directly contacts when being used for the corrosive gas filtration, reduced the corrosion to cylinder itself, has prolonged working life; Be applicable to various pulse dust collector.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Accompanying drawing 1 is the utility model embodiment's structure diagram.
Fig. 2 is the plan view of Fig. 1.
Each label is in the accompanying drawing: 1 cylinder; 2 connecting rods; 3 valve plates.
Embodiment
Embodiment as shown in Figure 1, the utility model is to connect connecting rod 2 by cylinder 1, and fore and aft motion is converted to the rotation of valve shaft, thereby makes valve plate 3 form on-off actions, deduster normal operation when valve plate 3 is opened; If stop the supple of gas or steam, cut off the power supply, cylinder 1 does not move, valve plate 3 is not affected by gravity and still keeps original open mode, guarantees the deduster normal operation.
Claims (1)
1. pulse dust collector off-line opening and closing device of attitude of remaining stationary of stopping the supple of gas or steam, it is characterized in that, it is to connect connecting rod (2) by cylinder (1), fore and aft motion is converted to the rotation of valve shaft, thereby make valve plate (3) form on-off action, when valve plate (3) deduster normal operation when opening; If stop the supple of gas or steam, cut off the power supply, cylinder (1) does not move, valve plate (3) is not affected by gravity and still keeps original open mode, guarantees the deduster normal operation.
