Description

Technical Field

[0001] The utility model belongs to the technical field of disc separators, and particularly relates to a heavy-phase discharge reflux device for a disc separator. Background Art

[0002] Conventional material slag removal separators generally select two-phase self-cleaning disc separators. For special materials, the requirement is slag removal, but at the same time, the loss of effective components is not allowed. Conventional two-phase self-cleaning disc separators cannot meet the requirements. According to the particularity of the material, a three-phase self-cleaning disc separator is used for separation, and at the same time, the discharge amount of the heavy phase is controlled. And the heavy phase flows out from the heavy-phase discharge port and then directly returns to the separator feed port and enters the separator together with the liquid to be separated again for separation, so as to achieve the purpose of slag removal while ensuring that the effective components are not lost. However, the existing heavy-phase discharge port of the three-phase self-cleaning disc separator only includes a feed port, a light-phase discharge port, and a heavy-phase discharge port, which is not convenient for controlling the discharge amount of the heavy phase, and the specific flow value cannot be displayed. At the same time, after the heavy-phase discharge port is connected to the feed pipe, there is also a problem of backflow, and the slag removal effect is not good. Content of the Utility Model

[0003] In view of the above problems, the main purpose of the utility model is to design a heavy-phase discharge reflux device for a disc separator, so as to realize the requirement of the discharge amount of the heavy phase separated by the three-phase self-cleaning disc separator, and at the same time, the separated heavy phase can smoothly return to the separator feed port and enter the separator together with the liquid to be separated again for separation.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A heavy-phase discharge reflux device for a disc separator includes a circuit installed at the heavy-phase discharge outlet; a manual ball valve, a flow meter, and a check valve are arranged on the circuit;

[0006] The manual ball valve is connected to the heavy-phase discharge outlet, the check valve is connected to the feed port, and the flow meter is respectively connected to the manual ball valve and the check valve through pipelines.

[0007] As a further description of the utility model, the pipeline includes a first connecting fitting and a second connecting fitting, and both the first connecting fitting and the second connecting fitting are arranged in a right-angle bend shape.

[0008] As a further description of the utility model, one end of the first connecting fitting is connected to the check valve, and the other end is connected to the flow meter.

[0009] As a further description of the utility model, one end of the second connecting fitting is connected to the manual ball valve, and the other end is connected to the flow meter.

[0010] As a further description of the present utility model, the manual ball valve, flow meter, check valve, and the pipeline connecting to the feed port form a square structure.

[0011] Compared with the prior art, the technical effects of the present utility model are as follows:

[0012] The present utility model provides a heavy-phase discharge reflux device for a disc separator, which includes a circuit installed at the heavy-phase discharge outlet. A manual ball valve, a flow meter, and a check valve are provided on the circuit. The manual ball valve is connected to the heavy-phase discharge outlet, the check valve is connected to the feed port, and the flow meter is respectively connected to the manual ball valve and the check valve through pipelines. By adjusting the manual ball valve, the discharge amount of the heavy phase can be controlled; by using the flow meter, the specific flow value can be displayed; by using the check valve, the flow direction of the heavy phase can be controlled to ensure that the heavy phase can only flow into the feed pipe, and the liquid in the feed pipe will not flow back into the heavy phase. The manual ball valve, flow meter, and check valve are connected by the first connecting fitting and the second connecting fitting to form a passage, and this passage is connected to the feed pipeline and the joint seat to form a circuit, so that the separated material can achieve the purpose of slag removal after being separated by the three-phase disc self-cleaning separator, and at the same time ensure that the effective components are not lost.
