The utility model discloses a drainage device used for a vacuum tank. The drainage device comprises a water storage tank, wherein the top of the water storage tank is provided with a communicating pipe, a first vent pipe and a second vent pipe, the bottom of the water storage tank is provided with a drainage pipe, one end of the communicating pipe is communicated with the bottom of the vacuum tank, the bottom of the vacuum tank is communicated with the water storage tank, one end of the second vent pipe is communicated with the top of the vacuum tank, the top of the vacuum tank is communicated with the water storage tank, one end of the first vent pipe is arranged on the top of the water storage tank, and the other end of the first vent pipe is communicated with compressed air or atmosphere. The water storage tank is used for collecting water in the vacuum tank and then is externally connected with the first vent pipe, when the water storage tank drains water, the first vent pipe can be used for enabling pressure in the water storage tank to reach atmospheric pressure or exceed the atmospheric pressure, so that the difficult problem that the drainage effect is poor under negative pressure in the prior art is solved, and the drainage effect is greatly improved.
Description
Technical field
The utility model relates to a kind of drainage means for vacuum tank.
Background technique
Vacuum tank is a kind of pressurized container that stores negative pressure air that is specifically designed to, and it is generally connected with vacuum pump, forms evacuated air station, for other equipment provide vacuum suction service.
Because vacuum pump need to add unloading operation frequently, therefore, at the inner meeting of vacuum tank some water of existence more or less, therefore existing vacuum tank has corresponding drainage means.Existing drainage means mainly refers to that the bottom of vacuum tank arranges pipe, and the outer end of pipe arranges drain valve.But, this simple discharge structure effect extreme difference in actual applications, this is because vacuum pump inside is negative pressure state, is difficult to inner water to discharge under the atmospheric effect in the external world.
For the problems referred to above, someone proposes to arrange one or more water pump 12 on pipe, relies on the draft of the water pump draining that absorbs water, shown in accompanying drawing 1.But technique scheme exists the shortcomings such as power consumption is high, rate of fault is high, and the effect of water suction draining is also bad.
Summary of the invention
The utility model object is to provide a kind of drainage means for vacuum tank.
For achieving the above object, the technical solution adopted in the utility model is: a kind of drainage means for vacuum tank, comprise water storage tank, and the top of water storage tank is provided with connecting tube, the first breathing pipe and the second breathing pipe, and the bottom of water storage tank is provided with waste pipe; One end of described connecting tube is communicated with the bottom of vacuum tank, and the bottom of vacuum tank is communicated with water storage tank; Be provided with the first valve connecting tube; One end of described the second breathing pipe is communicated with the top of vacuum tank, and the top of vacuum tank is communicated with water storage tank; Described the second breathing pipe is provided with the second valve; The top of water storage tank is located in one end of described the first breathing pipe, and the other end is communicated with pressurized air or atmosphere; Described the first breathing pipe is provided with reduction valve and the 4th valve; Described waste pipe is provided with the 3rd valve; In described water storage tank, be provided with at least 1 liquid level sensor.
Above, described liquid level sensor is existing equipment, is used for detecting the height of liquid level in water storage tank, and outside transmission of signal, so that switch valve carries out draining or closes in time.
In technique scheme, in described water storage tank, be provided with from top to bottom 3 liquid level sensors.
In technique scheme, be also provided with control system, described reduction valve and each valve are by control system control.
Described control system can adopt PLC control panel, thereby realizes the automatic control of whole device.
In technique scheme, described first to fourth valve is pneumatic valve.
Because technique scheme is used, the advantage that the utility model compared with prior art has is:
1, the utility model design has obtained a kind of new drainage means for vacuum tank, utilize water storage tank to collect the water in vacuum tank, then at external the first breathing pipe, and its one end is communicated with pressurized air or atmosphere, thereby, when water storage tank draining, can make the pressure in water storage tank reach barometric pressure or exceed barometric pressure by the first breathing pipe, thereby solved in prior art the not good difficult problem of draining under negative pressure, greatly improved drainage effect.
2, the utility model can be realized Auto-drainage by control system, thereby has good operability, practicability, and is combined well with existing manufacturing mechanism, is suitable for applying.
3, the utility model is simple in structure, is convenient to preparation, and failure rate is low, consumes energy lowly, and operating cost is lower.
4, the first breathing pipe of the present utility model can connect pressurized air, makes the pressure in water storage tank exceed barometric pressure, thereby can accelerate drainage rate.
