As shown in fig. 1, the utility model provides an anti-pollution discharge device for purified water storage tanks and injection water storage tanks, which comprises a storage tank, wherein a liquid inlet is formed in the upper end surface of the storage tank 1, a liquid inlet pipe 2 is arranged at the liquid inlet, and a liquid inlet valve is arranged on the liquid inlet pipe 2; the lower end surface of the storage tank 1 is provided with a liquid outlet, a liquid outlet pipe 4 is arranged on the liquid outlet, and a liquid outlet valve 5 is arranged on the liquid outlet pipe 4.
The lower end of the liquid discharge pipe 4 is connected with a sewer pipeline 6, the lower end of the liquid discharge pipe 4 is connected with the upper end of the sewer pipeline 6, and purified water or injection water in the storage tank 1 is discharged from the sewer pipeline 6.
The upper end face of the storage tank 1 is further provided with an air inlet, an air inlet pipeline 8 is arranged at the air inlet, and the air inlet pipeline 8 is communicated with the inside of the storage tank 1. 8 way upward of intake pipe has set gradually bacteria removing filter 9, relief pressure valve 10, air inlet valve 11 along the direction of keeping away from the air inlet, the one end that air inlet valve 11 kept away from relief pressure valve 10 is provided with compressed air inlet pipeline 12, the one end of compressed air inlet pipeline 12 is connected with relief pressure valve 10, and the other end is connected with air compressor's gas outlet, and air compressor lets in compressed air to storage tank 1 inside through compressed air inlet pipeline 12 and air inlet pipeline 8.
The air inlet valve 11 is used for controlling whether compressed air can enter the storage tank; the pressure reducing valve 10 is used for adjusting the air inlet pressure to a certain required value and automatically keeping the air inlet pressure stable by means of the energy of compressed air; the sterilizing filter 9 adopts a micro-filtration filter element with large specific surface area and filtering precision of more than 0.22 mu m, and is mainly used for preventing impurities, harmful bacteria, microorganisms and the like in the air from entering the tank body to cause the change of water quality and meet the process requirements in the production process of liquid medicine.
The upper end face of the storage tank 1 is further provided with a respirator port, a respirator pipeline 13 is arranged at the respirator port, a tank respirator 14 is arranged at one end, far away from the respirator port, of the respirator pipeline 13, and a respirator valve 15 is arranged on the respirator pipeline 13. Temperature variation or business turn over material can cause the too big pressure differential inside and outside storage tank 1, can cause a jar body to warp, and jar is with inside and outside atmospheric pressure of balanced storage tank of respirator 14, prevents that the positive pressure or negative pressure from appearing in storage tank 1 to prevent that storage tank 1 from causing the damage because of inside and outside pressure differential is too big.
A liquid flow sensor 7 is arranged at the joint of the drain pipe 4 and the sewer pipeline 6, and the liquid flow sensor 7 is used for detecting the flow of purified water or injection water flowing through the drain pipe 4.
The inside of the storage tank 1 is provided with a pressure sensor 16 for detecting the pressure inside the storage tank 1 in real time.
The liquid discharge valve 5, the liquid inlet valve 3, the respirator valve 15 and the air inlet valve 11 are electromagnetic valves.
The storage tank is characterized in that a controller and a storage battery are arranged outside the storage tank 1, the storage battery is electrically connected with the controller, the liquid flow sensor 7, the pressure sensor 16, the liquid discharge valve 5, the liquid inlet valve 3, the breather valve 15 and the air inlet valve 11, and the controller is electrically connected with the liquid flow sensor 7, the pressure sensor 16, the liquid discharge valve 5, the liquid inlet valve 3, the breather valve 15 and the air inlet valve 11.
The working principle of the utility model is as follows:
when the sterilization process of the water for injection and the purified water system is carried out to a discharge state, the controller controls the air inlet valve 11 to be opened, the respirator valve 15 and the liquid inlet valve 3 to be closed, the liquid outlet valve 5 is opened simultaneously, the compressed air enters the air inlet pipeline 8 through the compressed air inlet pipeline 12, the air inlet pressure value of the compressed air is kept at a set value under the action of the pressure reducing valve 10, the compressed air with stable pressure removes bacteria contained in the compressed air through the action of the sterilizing filter 9, and the sterilized compressed air enters the storage tank 1 through the air inlet pipeline 8.
The liquid discharge valve 5 is opened, and the inside rivers of storage tank 1 pass through fluid-discharge tube 4 and sewer pipe 6 and discharge, because inside compressed air entering storage tank 1 for the inside malleation state that keeps always of storage tank 1, rivers can directly discharge and can not take place to flow backward from fluid-discharge tube 4. The liquid flow sensor 7 can detect the flow signal all the way through the water flow is discharged.
When the water flow in the storage tank 1 is completely exhausted, the liquid flow sensor 7 detects that the flow in the liquid discharge pipe is zero, and cannot detect a flow signal, the liquid flow sensor 7 transmits the signal to the controller, and when the controller receives the signal that the flow is zero, the liquid discharge valve 5 is controlled to be closed, then the respirator valve 15 is controlled to be opened, and finally the air inlet valve 11 is controlled to be closed. Because before the flowing back valve 5 closes, compressed air gets into inside storage tank 1 all the time for the pressure in the storage tank 1 keeps the malleation state all the time, even the rivers in the storage tank 1 are totally evacuated, can not take place high temperature high pressure waste water, the circumstances of waste gas through the inside of pipeline backward filling into cleaned storage tank 1 like this. When the drain valve 5 is closed, the breather valve 15 is opened, so that the internal pressure and the external pressure of the storage tank 1 are kept consistent, water flow can enter the storage tank 1 again, and damage caused by overlarge internal and external pressure difference due to positive pressure or negative pressure in the storage tank 1 can be prevented. And finally, the air inlet valve 11 is closed, so that the situation that the inside of the storage tank 1 is not backwashed can be ensured.
The pressure sensor 16 can detect the pressure value inside the storage tank 1 in real time, when the air inlet pipeline 8 breaks down suddenly and air can not enter the storage tank, the pressure sensor 16 can detect that the pressure inside the storage tank 1 is abnormal, and transmits an abnormal signal to the controller, and the controller controls the liquid discharge valve 5 to be closed, so that backflow caused by negative pressure inside the storage tank 1 due to insufficient compressed air is prevented.
It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
