The vacuum exhaust fan has large air suction volume and needs a high rotating speed of the fan to maintain, the fan blade generally reaches 3000-3500 r/min, and when the stacking efficiency is high, the fan is not suitable for frequent start and stop, so that the air pipeline is switched to the atmosphere when the suction plate is not needed in control, the fan is prevented from always running under high load, and a large-flow switching valve is needed.
With the utility model discloses relevant prior art: the diameter of the port of the butt joint channel of the existing standard product is not large, for example, the largest switching valve VP3185 on an SMC manual has a maximum port of 2 inches (the diameter is 50.8 mm), the effective diameter is not 45 times longer than the wall thickness of the butt joint internal connecting pipe, in addition, the diameter of the piston in the valve is also larger, an overflow port is formed, and the ventilation effect is greatly reduced. Based on this, the utility model discloses a fast switch over vacuum and communicating device of atmosphere solves large-traffic, efficient ventilation problem.
The vacuum suction port of the exhaust fan is connected with the mechanical pressure relief valve, the electromagnetic directional valve and the sucker through an air pipe to form a vacuum pumping passage, and the air outlet of the exhaust fan is connected with the silencer to reduce noise.
When the plate is not sucked in the idle state, the electromagnetic directional valve is disconnected from the sucking disc, the exhaust fan is communicated with the atmosphere, and the fan is not stopped.
The prior art has the following disadvantages: the fan works under a large load for a long time, and accumulated heat cannot be dissipated, so that overheat protection shutdown is caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the vacuum suction plate stack production, the air exhauster is because of the shut down that leads to that generates heat, the problem of stopping the line. The utility model discloses a position nearest at the air exhauster increases a large-traffic pneumatic switching-over device, when non-operating condition, switches the pipeline to atmospheric pressure rapidly and communicates with each other.
The utility model provides an automatic breather in vacuum installs in air exhauster ventilation pipe way, when the non-effective operating condition of quick-witted wind, can dump the load operation, reduces self and generates heat, takes away the heat that normal during operation produced simultaneously, reaches heat balance, makes the air exhauster steady operation.
The utility model provides an automatic breather in vacuum includes the cylinder, takes a breath interface, main line interface, the main line interface of giving vent to anger, the passageway of taking a breath, sealed piece, the chamber of taking a breath, mounting panel, main line interface of admitting air and main line interface UNICOM of giving vent to anger, main line interface of admitting air and main line interface of giving vent to anger go up to be connected with the chamber of taking a breath through the interface of taking a breath, take a breath the other interface that is provided with in chamber, take a breath the chamber upper end and be provided with the cylinder, take a breath the intracavity and be provided with sealed piece, sealed piece connection cylinder, by cylinder control motion, the cylinder is connected with mounting panel screw mode for.
In the main air pipe, an additional 7 air exchange cavities that parallel, normally separate with main road is sealed, under the inoperative condition, PLC signals gives two-position cross two electric control solenoid valve, the cylinder return circuit is changed, cylinder 1 contracts back, sealed piece 6 contracts back along with the cylinder, air exchange channel 5 opens, main gas circuit 3 this moment, 4 and air exchange interface 2 switch-on, interface 2 connects outside atmospheric pressure, whole air exhaust return circuit is shortened rapidly, and outside cold air gets into behind trunk line and the air exhauster discharge rapidly, take away a large amount of heats, maintain the heat balance of fan.
Has the advantages that: the utility model discloses a when the purpose was for the non-effective operating condition of fan-induced air, can unload the operation, reduce self and generate heat, take away the heat that normal during operation produced simultaneously, reach heat balance, make air exhauster steady operation, solved the problem of narration in the background art.
