Abstract
The utility model relates to a buffer tank device, in particular to a buffer tank device which is applied at the front end of a water pumping system of a thermal power plant and is used for filtering impurities and buffering water flow. The buffer tank device is characterized by consisting of a vacuum pump, a filtering net, a buffer tank, a water discharging pipe and a water delivery pipe, wherein the vacuum pump is connected with the buffer tank by the water delivery pipe which is provided with a filtering net; the buffer tank is only provided with the water discharging pipe connected with the water pumping system; the buffer tank is provided with a water discharging valve, a sewage discharging valve and a vacuum meter; the water discharging valve is arranged at the middle-upper part of a tank body; the sewage discharging valve is arranged at the bottom of the tank body; and the vacuum meter is arranged at the top of the tank body. The buffer tank device has the advantages that the structural design is reasonable, the garbage can be effectively filtered, the impurities and the foreign matters are discharged in time, and the water flow is buffered.
Description
Technical field
The utility model relates to a kind of surge tank device, particularly a kind of front end that is applied in steam power plant's pumping system, the surge tank device of impurity screening and buffering current.
Background technology
Existing water intaking pump house is the most important thing of power plant's management as the forefront of power station water supply lifeline, and generally speaking, its main equipment is configured to centrifugal water pump, vacuum pump and pipe-line system.Start stop operation as the main equipment water pump of pump house is one of of paramount importance operation of pump house, but because of river water quality can not effectively guarantee, impurity such as inner inclusion rubbish, the grains of sand, stone, very easily cause the damage of main portion such as vacuum pump impeller, pump case cover in the process of suction air, supplying water ensures the potential safety hazard that existence is very big.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of reasonable in design, can effectively filter rubbish, in time discharges the impurity foreign matter, the surge tank device of buffering current.
It is this surge tank device that the utility model solves the problems of the technologies described above the technical scheme that is adopted, be characterized in: by vacuum pump, filter screen, surge tank, outlet pipe, water-supply-pipe is formed, described vacuum pump is connected by water-supply-pipe with surge tank, water-supply-pipe is provided with filter screen, on surge tank, establish and have only outlet pipe, described outlet pipe links to each other with pumping system, described surge tank is provided with draining valve, blowoff valve, vacuum meter, described draining valve is arranged on the middle and upper part of tank body, described blowoff valve is arranged on the bottom of tank body, and described vacuum meter is arranged on the top of tank body.
Water-supply-pipe between vacuum pump described in the utility model and the filter screen is provided with down ball valve.
Outlet pipe described in the utility model is provided with upper ball valve.
The utility model is compared with prior art and had the following advantages and effect: the use of present technique can make things convenient for and in time clear up tank interior deposition impurity rubbish.By the increase of this equipment, in start stop operation, impurity is effectively intercepted, and at the bottom of the overwhelming majority was deposited on jar, a jar internal upper part was an air, and the bottom is a water, and the purpose of vacuum pump suction system pipeline air obtains strong assurance from structure.Because of obtaining the buffering of tank body, the chance that current enter in the vacuum pump body also reduces greatly, and the best applying working condition of vacuum pump is guaranteed that well result of use highlights.Loss to the pump housing obviously descends.The application life of pump big leap ahead, (from returning no great maintenance in factory's maintenance 2-3 time nearly up till now 2 years in original 1 year) stability significantly promotes, operability is enhancing synchronously also.The water supply security protection obtains strong assurance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with embodiment the utility model is described in further detail, following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Embodiment 1: as shown in Figure 1, present embodiment is made up of vacuum pump 1, gas exhaust piping 2, following ball valve 3, filter screen 4, surge tank 5, outlet pipe 6, upper ball valve 7, water-supply-pipe 11, vacuum pump 1 is provided with gas exhaust piping 2, vacuum pump 1 is by linking to each other with surge tank 5 with water-supply-pipe 11, surge tank 5 is provided with outlet pipe 6, and outlet pipe 6 is provided with upper ball valve 7; Water-supply-pipe 11 is provided with down ball valve 3 and filter screen 4; The middle part of surge tank 5 is provided with draining valve 8 on the upper side, and the bottom is provided with blowoff valve 9, and the top is provided with vacuum meter 10.
In addition, need to prove, the specific embodiment described in this manual, its zero, the shape of parts, institute's title of being named etc. can be different.Allly conceive equivalence or the simple change that described structure, feature and principle are done, be included in the protection domain of the utility model patent according to the utility model patent.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present utility model or surmount the defined scope of these claims, all should belong to protection domain of the present utility model.
