Detailed Description

The principles and features of the present invention are described below in conjunction with the accompanying fig. 1, which is provided by way of example only to illustrate the present invention and not to limit the scope of the present invention.

Example one

A pump tank device for a cooling water system of an all-electric melting glass kiln is shown in figure 1 and comprises a reservoir 1, a first water suction pipe 2, a pump tank 3, a second water suction pipe 4, a water pump 5, a water pressing pipe 6 and a high-level water tower 7 which are sequentially communicated; the high-level water tower 7 is arranged above the reservoir 1 and is communicated with a cooling water pipe 8, and the cooling water pipe 8 is arranged at the bottom of the high-level water tower 7; an exhaust valve 9 is arranged above the pump tank 3; the second water suction pipe 4 is connected with a water injection pipe 12.

The water injection pipe 12 is connected with a water injection tank 14 through a water injection valve 13, the water injection tank 14 is communicated with a tap water pipe, and tap water continuously supplements water in the water injection tank 14, so that the water consumption of pump irrigation can be met.

The first water suction pipe 2 and the second water suction pipe 4 extend upwards from the bottom of the pump tank 3 to the inside of the pump tank 3, and the first water suction pipe 2 is higher than the second water suction pipe 4, that is, the interface between the first water suction pipe 2 and the pump tank 3 is higher than the interface between the second water suction pipe 4 and the pump tank 3. The water in the water injection tank 14 enters the pump tank 3 through the second water suction pipe 4, and when the water level in the pump tank 3 is higher than that in the first water suction pipe 2, the water flows into the first water suction pipe 2.

A check valve 11 is arranged at the communication end of the first water suction pipe 2 and the water storage tank 1, so that water in the first water suction pipe 2 is prevented from flowing into the water storage tank 1; the first water absorption pipe 2 extends downwards to a position below the liquid level of the water storage tank 1, and water is absorbed from the water storage tank 1 when the water pump 5 works normally.

The second water suction pipe 4 is provided with a water discharge valve 10, so that water is discharged when the water suction pipe is cleaned and maintained conveniently.

The valves in this embodiment, such as the exhaust valve 9, the drain valve 10, and the fill valve 13, may be electrically controlled valves.

The working process of the utility model is as follows: before starting the water pump 5, firstly, the water injection valve 13 is opened, water in the water injection tank 14 enters the pump tank 3 through the second water suction pipe 4, the exhaust valve 9 is opened for exhausting while water is injected, and the exhaust valve 9 is closed after exhausting is finished. When the water level in the pump tank 3 is higher than the first water suction pipe 2, water flows into the first water suction pipe 2, the pump tank 3, the first water suction pipe 2 and the second water suction pipe 4 are filled with water, the water pump 5 is started, and the water injection valve 13 is closed after normal water suction.
