Detailed Description

The present invention will be more clearly and completely described below with reference to the accompanying drawings.

FIG. 1 shows a dual tank material delivery system comprising: two tanks 100, two main lines and a third shut-off valve 600. The storage tank 100 is used for storing materials, the first stop valve 200, the rotor pump 300, the check valve 400 and the second stop valve 500 are sequentially installed on the main line, and two ends of the third stop valve 600 are connected to a pipeline between the first stop valve 200 and the rotor pump 300 in the two main lines through pipelines.

In this scheme, different materials are contained in two storage tanks 100, and two main lines are main line A and main line B respectively. In normal use, the third shut-off valve 600 is in a normally closed state, and the main line a and the main line B respectively convey the materials in the two storage tanks 100. When the rotor pump 300 in the main line a fails, but the material conveyed by the original main line a still has a conveying demand, the first stop valve 200 on the main line B is closed, the third stop valve 600 is opened, and the rotor pump 300 on the main line B is started, at this time, the material in the storage tank 100 connected to the main line a is output through the first stop valve 200 and the third stop valve 600 on the main line a, and the rotor pump 300, the check valve 400 and the second stop valve 500 on the main line B. The third stop valve 600 connects the two main lines, so that when the rotor pump 300 of one main line fails, the materials in the connected storage tank 100 can still be conveyed through the other main line, and the influence on production is avoided.

In this embodiment, the dual-tank material conveying system further includes two filters 700, the two filters 700 are respectively located on the two main pipelines, and the filters 700 are installed on the pipeline between the rotary pump 300 and the third stop valve 600. Filter 700 can filter the impurity in the storage tank, prevents that impurity from being exported and influencing product production quality.

In addition, the double-storage-tank material conveying system further comprises two fourth stop valves 800, the two fourth stop valves 800 are positioned on the two main pipelines, and the fourth stop valve 800 is installed on the pipeline between the filter 700 and the third stop valve 600. The fourth stop valve 800 can close the pipelines on both sides of the third stop valve 600 when the third stop valve 600 is overhauled, and leakage of materials is avoided. In addition, the safety of the main line can be enhanced by the fourth cut-off valve 800, and the safety and reliability of the system can be guaranteed when the first cut-off valve 200 fails.

In order to reduce the degree of mixed contamination of the materials in the two storage tanks 100 in the piping when the materials in the storage tank 100 connected to the main line a are transferred using the main line B, the dual-tank material transfer system further includes two first empty ball valves 910, the two first empty ball valves 910 are located on the two main lines, and the inlets of the first empty ball valves 910 are connected to the piping between the filter 700 and the impeller pump 300. The first emptying ball valve 910 is capable of emptying the original material in the line between the rotodynamic pump 300 and the tank 100 in the main line B.

In addition, the double-storage-tank material conveying system further comprises two second emptying ball valves 920, the two second emptying ball valves 920 are positioned on two main pipelines, and inlets of the second emptying ball valves 920 are connected to a pipeline between the check valve 400 and the second stop valve 500. The second emptying ball valve 920 can empty the materials in the pipeline communicated with the output port of the rotor pump 300 in the main line B, and further reduce the mixed pollution degree of the materials in the two storage tanks 100 in the pipeline.

In other embodiments, when the number of the storage tanks and the main lines is more than two, a third stop valve may be connected between adjacent main lines to achieve the purpose of mutual backup of the rotor pumps 300 on each main line, and avoid that a certain rotor pump fails to affect production.
