Description
Technical Field
The utility model belongs to the technical field of alumina production equipment and specifically relates to a overhead valve connection structure of overhead tank.
Background
Dense phase conveying is a common method for conveying fresh alumina, and the used device has the characteristics of simple structure, reliable operation, energy consumption saving, operation cost saving and the like. The pressure tank is a core device for dense phase conveying, and comprises a blanking valve, a bell valve, a pressurizing valve, a conveying valve and the like, wherein the conveying process comprises three processes of feeding, conveying and stopping. During wherein carry, the pressurization operation that the pressure valve can constantly open and close according to tank internal pressure, along with the reduction of material, tank internal pressure diminishes, and the pressure valve is opened after the lower limit value, and tank internal pressure crescent is after the upper limit value, and the pressure valve is closed to satisfy in the jar and accomplish whole transportation process in relatively stable pressure. The whole conveying process is controlled by a PLC, an electromagnetic pneumatic butterfly valve is adopted as an original pressurizing valve, and pressurizing operation is carried out in a mode that a cylinder drives a butterfly valve to be opened and closed. Because the material pressurization valve can carry out the action of opening and closing 120 times or so when conveying a jar of material, 80 jars of material are beaten in one day, and the butterfly valve action exceeds 1000 times, lead to the butterfly valve wearing and tearing to accelerate, appear pressurizing the butterfly valve and seal the damage, the gas leakage phenomenon appears, influence process flow, and equipment trouble is many, and spare parts consumes greatly.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a longer overhead tank pressure valve connection structure of life is provided.
The utility model provides a technical scheme that its technical problem adopted is: pressure tank force (forcing) valve connection structure, including setting up the manual stop valve on the pipeline, pipeline one end and pressurized gas pipeline intercommunication, the other end and pressure tank intercommunication, including setting up the diaphragm valve body on the pipeline, manual stop valve sets up between diaphragm valve body and pressurized gas pipeline, is provided with solenoid valve coil on the diaphragm valve body, and the export of diaphragm valve body and pressure tank intercommunication.
Further, the solenoid valve coil is communicated with an output point of the PLC control end.
Further, the manual stop valve and the diaphragm valve body are arranged on the same horizontal plane.
Further, a diaphragm is arranged in the diaphragm valve body, and the diaphragm is detachably arranged in the diaphragm valve body.
The utility model has the advantages that: in practical use, the diaphragm valve body is adopted to replace the original pneumatic butterfly valve, and the electromagnetic valve is used for directly controlling the diaphragm valve body so as to realize pressurization operation, so that the advantages of good sealing performance, long service life, simple maintenance and the like of the diaphragm valve body are fully exerted. After the diaphragm valve body is adopted, the faults of the pressurizing valve are few, and the pressurizing valve has positive effects on production and personnel. Meanwhile, only the diaphragm in the diaphragm valve needs to be replaced after the diaphragm valve is damaged, and the spare part cost is low. The utility model is particularly suitable for the connecting pipeline of the pressure valve of the alumina pressure tank.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Labeled as: manual stop valve 1, solenoid valve coil 2, diaphragm valve body 3, pressurized gas pipeline 4, diaphragm valve body export 5, pipeline 6.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1, the pressure tank pressure valve connecting structure comprises a manual stop valve 1 arranged on a pipeline 6, one end of the pipeline 6 is communicated with a pressurized gas pipeline 4, the other end of the pipeline is communicated with the pressure tank, the pressure tank pressure valve connecting structure comprises a diaphragm valve body 3 arranged on the pipeline 6, the manual stop valve 1 is arranged between the diaphragm valve body 3 and the pressurized gas pipeline 4, an electromagnetic valve coil 2 is arranged on the diaphragm valve body 3, and an outlet 5 of the diaphragm valve body is communicated with the pressure tank. A diaphragm is arranged in the generally preferred diaphragm valve body 3, and the diaphragm can be detachably arranged in the diaphragm valve body 3, so that the subsequent disassembly and replacement are convenient.
The utility model discloses can reform transform on former pipeline can. In practical use, because manual stop valve 1 mainly used diaphragm valve body 3 overhauls, generally, manual stop valve 1 is normally open. The diaphragm valve body 3 is connected using a suitable pipeline 6, the diaphragm valve body outlet 5 of the diaphragm valve body 3 communicating with the pressure tank. When the pressure tank equipment works, the electromagnetic valve coil 2 of the diaphragm valve body 3 can be selectively connected with a PLC control end output point, the electromagnetic valve coil 2 is electrified, the diaphragm valve body 3 is opened, the tank body of the pressure tank starts to be pressurized, when the pressure in the pressure tank rises to a certain value, the electromagnetic valve coil 2 is electrified, compressed air does not enter the tank any more, the pressure in the tank drops to a certain value, at the moment, the electromagnetic valve coil 2 is electrified again, and the process is circulated until the whole conveying process is completed. Generally, in order to facilitate later-stage maintenance, it is preferable that the manual shutoff valve 1 and the diaphragm valve body 3 are disposed on the same horizontal plane, so as to facilitate operation.
