Description

Technical Field

[0001] The utility model relates to the technical field of disc separators, and specifically refers to an operating liquid control structure of a disc separator. Background Art

[0002] A disc separator is a high-speed separation device, which is applied to related fields such as fruit juice clarification, oil-water separation, and biopharmaceuticals; the automatic slag-discharging type disc separator uses operating water to control the closing and opening of the drum through a PLC program, so as to realize the slag-discharging operation during the separation process. The following problems exist in the actual production process: (1) For some materials to be separated, the liquid density is relatively high, and using water as the operating water cannot reach the sealing pressure, resulting in the drum being unable to be normally closed; (2) During the slag-discharging process, the discharged solids will cause a certain degree of pollution to the operating water, resulting in the operating water being unable to be directly discharged or recycled. Therefore, an operating liquid control structure of a disc separator using the original liquid as the operating liquid is proposed. Summary of the Invention

[0003] The purpose of the utility model is to propose an operating liquid control structure of a disc separator to solve the above problems.

[0004] To achieve the above purpose, the utility model provides the following technical solutions: An operating liquid control structure of a disc separator, which is characterized by including a bypass pipeline connected to the feed pipeline on the disc separator, a filter connected to the bypass pipeline, and an operating liquid storage tank with one end connected to the filter and the other end connected to the disc separator; an operating liquid recovery pipeline is also connected between the disc separator and the feed pipeline.

[0005] Preferably, an operating liquid inlet pipeline is connected between the operating liquid storage tank and the disc separator.

[0006] Preferably, an operating liquid recovery storage tank is connected to the operating liquid recovery pipeline.

[0007] Preferably, a liquid level sensor and a pump are connected to both the operating liquid recovery storage tank and the operating liquid storage tank.

[0008] Preferably, a first control valve is also connected to the bypass pipeline.

[0009] Preferably, it further includes a clear liquid recovery pipeline connected to the filter and the clear liquid discharge pipe on the disc separator.

[0010] Preferably, a second control valve is connected to the clear liquid recovery pipeline.

[0011] Advantages of the present utility model: By using a branch pipeline to transport the material to be separated to a filter for filtration, the filtered stock solution enters the operating liquid storage tank for storage, and then is transported to a disc separator to replace other operating liquids for use, avoiding the situation where sealing cannot be achieved due to insufficient sealing pressure when the density of the material liquid is too high. At the same time, it also avoids the pollution of the operating water during the slag discharge process, resulting in the inability to directly discharge, reducing the impact of the separator on the environment;

[0012] By using the operating liquid recovery pipeline to recover the excess operating liquid to the feed pipeline for continuous recycling, the consumption of water resources is reduced. Description of the Drawings

[0016] Next, we will further explain the operating liquid control structure of a disc separator according to the present utility model with reference to the drawings.

[0017] Participate in the attachment Figure 1-2 As shown, in this embodiment, the operating liquid control structure of a disc separator includes a branch pipeline 1 connected to the feed pipeline 7 on the disc separator, a filter 2 connected to the branch pipeline 1, and an operating liquid storage tank 3 with one end connected to the filter 2 and the other end connected to the disc separator; an operating liquid recovery pipeline 4 is also connected between the disc separator and the feed pipeline 7; a first control valve 101 is further connected to the branch pipeline 1; an operating liquid inlet pipeline 5 is connected between the operating liquid storage tank 3 and the disc separator; by using the branch pipeline 1 to transport the material to be separated to the filter 2 for filtration, the filtered stock solution enters the operating liquid storage tank 3 for storage, and then is transported to the disc separator through the operating liquid inlet pipeline 5 to replace other operating liquids for use, avoiding the situation where sealing cannot be achieved due to insufficient sealing pressure when the density of the material liquid is too high. At the same time, it also avoids the pollution of the operating water during the slag discharge process, resulting in the inability to directly discharge, reducing the impact of the separator on the environment; by using the operating liquid recovery pipeline 4 to recover the excess operating liquid to the feed pipeline 7 for continuous recycling, the consumption of water resources is reduced.

[0018] Participate in the appendix Figure 1-2 As shown, an operating liquid recovery storage tank 401 is connected to the operating liquid recovery pipeline 4; a liquid level sensor 402 and a pump 403 are connected to both the operating liquid recovery storage tank 401 and the operating liquid storage tank 3; by using the liquid level sensor 402 to sense the liquid levels on the operating liquid recovery storage tank 401 and the operating liquid storage tank 3, the first control valve 101 is controlled to supplement the operating liquid to the operating liquid storage tank 3 in a timely manner and use the pump to extract the operating liquid in the operating liquid recovery storage tank 401 into the feed pipeline and enter the disc separator for separation, thereby realizing automatic control.

[0019] Participate in the appendix Figure 1-2 As shown, it also includes a clear liquid recovery pipeline 6 connected to the clear liquid discharge pipe 8 on the filter 2 and the disc separator; a second control valve 601 is connected to the clear liquid recovery pipeline 6; part of the clear liquid is recovered through the clear liquid recovery pipeline 6 into the filter 2, filtered and then stored in the operating liquid storage tank 3 for use as the operating liquid. The clear liquid has a low solid content after separation, which can reduce the burden on the filter 2, reduce losses and cleaning frequency;

[0020] During the use process of the present utility model, the first control valve 101 is opened, the material to be separated in the feed pipeline 7 enters the filter 2 through the branch pipeline 1, the original liquid filtered by the filter 2 enters the operating liquid storage tank 3 for storage, and then the original liquid in the operating liquid storage tank 3 is transported to the disc separator by the pump 403 for use as the operating liquid. The excess operating liquid after being used by the disc separator enters the operating liquid recovery storage tank 401 through the operating liquid recovery pipeline 4 for storage. The liquid level sensor 402 senses the liquid levels on the operating liquid recovery storage tank 401 and the operating liquid storage tank 3. When the liquid level of the operating liquid recovery storage tank 401 is higher than the set height, the liquid level sensor 402 sends a signal to the control system, and the control system controls the pump 403 to transport the operating liquid in the operating liquid recovery storage tank 401 into the feed pipeline 7 and enter the disc separator for separation. When the liquid level of the operating liquid storage tank 3 is lower than the set height, the liquid level sensor 402 sends a signal to the control system, and the control system controls the first control valve 101 to open. The material to be separated in the feed pipeline 7 enters the filter 2 through the branch pipeline 1, and the original liquid filtered by the filter 2 enters the operating liquid storage tank 3 for storage;

[0021] At the same time, when the clear liquid is discharged through the clear liquid discharge pipe 8 after separation, the control system can also control the second control valve 601 to open, and the clear liquid enters the filter 2 through the clear liquid recovery pipeline 6, and after being filtered, enters the operating liquid storage tank 3 for use as the operating liquid;
