Abstract
The utility model discloses a non-pump liquid-sucking device which can extract strongly acid from a storage tank. In the device, the outer part of the storage tank is provided with an air compressor which is connected with the storage tank through a gas conveying pipe, and the wall of the storage tank is provided with liquid outlet holes. The utility model can overcome the defects of easy corrosion of a pump and the occurrence of the phenomenon of oil leakage at the time of acid extraction. The utility model has no motion mechanical corrosion, no leakage and no pollution at the time of the acid extraction, has the advantages of simple structure, convenient operation, safety and high durability, and is suitable for extracting different corrosive liquid.
Description
The utility model relates to a kind of Non-pump liquid-sucking device, relates in particular to a kind of device that extracts strong acid from storage tank.
For a long time, industrial enterprise all is with withstanding corrosion storage tank storage acid, takes out acid with noncorrosive pump, but when extracting as strong acid such as red fuming nitric acid (RFNA)s, the operator can worry about to inherently safe, because the corrosion resistance of pump is limited, the parts of pump are immersed in corrosion easily in the strong acid liquid for a long time; Non-corrosion resistant parts such as electrical motor and support thereof also are subjected to the invasion and attack of acid or acid mist easily near acid solution and corrode gradually; Owing to making the pump shaft place leak acid solution, mechanical wear corrodes steel part in addition.In a single day pump can be caused cisco unity malfunction by attack by acid in a word, and leakage phenomenon also can cause waste, burns out pump base and ground, even jeopardizes personal safety.Repair or change this class pump and cost a lot of money, also bring certain influence simultaneously to production.
The purpose of this utility model provides a kind of Non-pump liquid-sucking device that does not have parts burn into no leak phenomenon, and easy to operate, safe and reliable, durable in use.
For achieving the above object, Non-pump liquid-sucking device of the present utility model comprises storage tank, is provided with Air compressor in the storage tank outside, is connected by gas piping between Air compressor and the storage tank, and tank wall is provided with fluid hole.
After adopting such structure,, make acid solution in the storage tank outside fluid hole flows out jar by the air pressure effect because the utility model is to be formed by connecting by gas piping by Air compressor and storage tank, thus the movable machinery corrosion do not had when taking out acid, no leak, pollution-free.It is bad and leakage phenomenon occurs by attack by acid easily that it has overcome when taking out acid with pump pump, and causing repairing pump, to change the pump expense big, and shortcomings such as influence production, and simple in structure, easy to operate, safety durable are particularly suitable for extracting various corrosive liquid.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the scheme drawing of a kind of specific embodiment of Non-pump liquid-sucking device of the present utility model.
As seen from Figure 1, Non-pump liquid-sucking device of the present utility model is made up of Air compressor 1, storage tank 2, storage tank 3, is connected by gas piping 4 between Air compressor 1 and the storage tank 2, is connected by gas piping 5 between storage tank 2 and the storage tank 3, and gas piping 5 is provided with valve 6; Storage tank 3 walls are provided with fluid hole 7, are provided with hydraulic pipe 8 in the storage tank 3, and this pipe import of 8 is near storage tank 3 bottoms, and outlet is connected with fluid hole 7 on storage tank 3 walls.The bottom of storage tank 3 and hydraulic pipe 8 import correspondence positions are provided with groove 9.Be provided with arm and valve 10 in the stage casing of gas piping 5, valve 10 is opened when advancing acid and is used for air in the drain tank; Storage tank 3 is provided with acid inlet tube road junction 11 and sewage draining exit 12, and bigger storage tank also is provided with manhole 13.Described storage tank is a leakproof tank, can bear certain pressure.
During use, acid solution enters in the storage tank 3 from acid inlet tube road junction 11, opens valve 10 simultaneously, the air in the let-down vessel 3, and after the acid solution can in the storage tank 3 is intact, shutoff valve 10.When taking out acid, connect the power supply of the electrical motor of Air compressor 1, open valve 6 simultaneously, air enters gas piping 4, storage tank 2 by the freeing pipe of Air compressor 1 successively, in gas piping 5 enters storage tank 3.Because Air compressor 1 is constantly exerted pressure to inflation in the storage tank 3, make pressure in the storage tank 3 gradually greater than the pressure in the hydraulic pipe 8, the acid solution face in the hydraulic pipe 8 then is higher than the acid solution face in the storage tank 3 gradually, and acid solution constantly rises, and flows out from the outlet of hydraulic pipe 8 at last.Again since the import of hydraulic pipe 8 near storage tank 3 bottoms, corresponding with groove 9 positions, acid solution flows out from here, flows out the outlet of hydraulic pipes 8 through fluid hole 7, acid solution can extract very totally like this.In the time of need not taking out acid, Air compressor 1 quits work, and valve 6 also cuts out thereupon, enters its piston of Air compressor internal corrosion, cylinder to prevent the sour vapour acid mist refluence in the storage tank 3.
Non-pump liquid-sucking device of the present utility model can also be provided with fluid hole 7 on storage tank 3 bottoms or two side, hydraulic pipe 8 outer being connected on the fluid hole 7 also can be realized the purpose of this utility model.
