Description
Technical field
The utility model relates to a kind of warning device, and especially a kind of pulse self-cleaning air filter compressed air anti-leak warning device, belongs to the technical field of self-cleaning strainer.
Background technology
Pulse self-cleaning air filter is a kind of new and effective air cleaner with automatic ash removing function.In air filtering process, absorption due to dust makes the inside and outside differential pressure of the air stream flowing through efficient filter core progressively increase, when the inside and outside differential pressure of filter element is greater than a certain setting value, " impulse controller " namely starts automatically, it controls " impulse electromagnetic valve " has the pulsed backwash of program from inside to outside to often arranging filter core, to remove the laying dust be adsorbed on filter core with compressed air within the extremely short time; When filter core is rinsed well (inside and outside differential pressure is less than a certain setting value or backwash after several times circulation), flushing process stops voluntarily.
Compressed air be pulse self-cleaning air filter indispensable from clear medium, and compressed-air actuated pressure directly affects self-purging effect.Compressed air pressure should be not less than 0.4MPa, is not more than 0.8MPa, and when compressed air pressure is too low, differential pressure inside and outside clear rear filter core can be caused still to be greater than " impulse controller " pneumatic setting value, and pulse self-cleaning air filter can be in from clear state always.Compressed air leakage is one of its hypotensive main cause.
Conventional restriction orifice prevents compressed air leakage at present.This method can not stop from source leaks, and compressed air air demand can be caused to can not meet pulse self-cleaning air filter from clear requirement.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, and provide a kind of pulse self-cleaning air filter compressed air anti-leak warning device, its compact conformation, effectively can prevent compressed air leakage, automaticity is high, safe and reliable.
According to the technical scheme that the utility model provides, described pulse self-cleaning air filter compressed air anti-leak warning device, comprises for the compressed air inlet pipe receiving compressed-air actuated discharge and be connected with described discharge; Described compressed air inlet pipe is provided with magnetic valve, and described magnetic valve is connected with leakage-resisting controller, and described leakage-resisting controller also with for monitoring the pressure switch of pressure state in discharge is connected.
Described leakage-resisting controller is also connected with micro-pressure-difference transmitter.
Advantage of the present utility model: judged the air pressure in discharge by pressure switch and micro differential pressure switch, leakage-resisting controller is when judging gas leakage, and energy output alarm signal, to overhaul in time; Leakage-resisting controller is by the on off state of controller Controlling solenoid valve, and can monitor the air-suction state in discharge, compact conformation, effectively can prevent compressed air leakage, automaticity is high, safe and reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Description of reference numerals: 1-magnetic valve, 2-leakage-resisting controller, 3-pressure switch, 4-discharge, 5-micro-pressure-difference transmitter and 6-compressed air inlet pipe.
Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in Figure 1: in order to effectively compressed air leakage can be prevented, improve automaticity, the utility model comprises for the compressed air inlet pipe 6 receiving compressed-air actuated discharge 4 and be connected with described discharge 4; Described compressed air inlet pipe 6 is provided with magnetic valve 1, and described magnetic valve 1 is connected with leakage-resisting controller 2, and described leakage-resisting controller 2 is also connected with the pressure switch 3 for monitoring pressure state in discharge 4.
In the utility model embodiment, compressed air enters in discharge 4 by compressed air inlet pipe 6, is stored by discharge 4 pairs of compressed air.Magnetic valve 1 is in normally off, and magnetic valve 1 can be opened by leakage-resisting controller 2, and when magnetic valve 1 is opened, compressed air enters in discharge 4 by compressed air inlet pipe 6.The structure that leakage-resisting controller 2 can adopt the art conventional, as PLC etc., specifically repeats no more.Compressed-air actuated air pressure is generally 0.4MPa ~ 0.8MPa.
Further, described leakage-resisting controller 2 is also connected with micro-pressure-difference transmitter 5.Micro-pressure-difference transmitter 5, for connecting in air and pulse self-cleaning type filter, monitors the pressure reduction in described pulse self-cleaning type filter by micro-pressure-difference transmitter 5.When passing through the pressure in pressure switch 3 detected set tracheae 4 lower than setting value, leakage-resisting controller 2 judges whether the input pressure value of micro-pressure-difference transmitter 5 is less than from clear setting value, when being less than from clear setting value, leakage-resisting controller 2 makes magnetic valve 1 close, block to the air inlet in discharge 4, leakage-resisting controller 2 is to administrative staff or user's output alarm signal; And when being greater than from clear setting value, leakage-resisting controller 2 makes magnetic valve 1 stay open state.
The utility model judges the air pressure in discharge 4 jointly by pressure switch 3 and micro-pressure-difference transmitter 5, leakage-resisting controller 2 is when judging gas leakage, and energy output alarm signal, to overhaul in time; Leakage-resisting controller 2 is by the on off state of Controlling solenoid valve 1, and can monitor the air-suction state in discharge 4, compact conformation, effectively can prevent compressed air leakage, automaticity is high, safe and reliable.
