Description

Technical Field

[0001] This utility model relates to the field of ceramic membrane filtration technology, and in particular to a silicon carbide ceramic membrane filtration device for powder washing. Background Technology

[0002] Existing powder washing processes mostly employ plate and frame filter presses for solid-liquid separation. A batch of liquid is circulated multiple times to remove impurities such as iron ions from the powder. However, due to factors such as process and equipment, many problems and drawbacks exist:

[0003] 1. Plate and frame filter cloth has low filtration accuracy. During solid-liquid separation, some powder will pass through the filter cloth under pressure and flow away with the sewage, resulting in the loss of raw materials. This leakage phenomenon will waste about 10% of the material.

[0004] 2. Due to the structural limitations of plate and frame filter presses, the filter cloth will be damaged after a period of use and needs to be replaced immediately. However, replacement is difficult and requires a lot of manpower and resources.

[0005] 3. Because plate and frame equipment is used to frequently separate solid and liquid in a batch of material, it will cause a lot of water waste, and the powder will be discharged with the permeate, which will cause certain harm to the environment.

[0006] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0024] See Figures 2-4Preferably, the aeration component of this utility model includes an aeration blower 14 and a fifth pipe 15. The fifth pipe 15 is connected to the membrane reaction tank 1 and is located at the bottom of the membrane reaction tank 1. By turning on the aeration blower 14 during the filtration process, the mixing can be made more uniform and thorough.

[0025] See Figure 4 In addition, the bottom of the membrane reaction tank 1 of this utility model is provided with a drain pipe 16, which facilitates the discharge of wastewater.

[0026] See Figure 3 Furthermore, each of the several membrane box groups 18 of this utility model is provided with several ceramic membranes 19, and filtration can be achieved by setting ceramic membranes 19 in the membrane box group 18.

[0027] See Figures 1-4 Even better, the membrane reaction tank 1 of this utility model is provided with a ladder 17 on the side away from the support base 2, so that the staff can easily watch and monitor the operation inside the membrane reaction tank 1.

[0029] The working principle of this utility model:

[0030] After the powdered feed liquid enters the membrane reactor 1, impurities such as iron ions in the feed liquid pass through the micropores on the surface of the ceramic membrane 19 and enter the internal chamber of the ceramic membrane 19, where they collect and flow into the wastewater tank or the wastewater tank via the drain pipe 16. Meanwhile, the powder particles that need to be washed are retained inside the membrane reactor 1 for repeated rinsing and purification. At the same time, this invention is equipped with an aeration component, which keeps the aeration blower 14 running during operation, generating a certain amount of disturbance to prevent powder from agglomerating on the surface of the ceramic membrane 19 and clogging the membrane pores. This invention is also equipped with a backwash pump 9 and a backwash filter 10, which can backwash over time during operation. Under the driving force of the backwash pump 9, clean water flows backward from the internal chamber of the ceramic membrane 19 through the membrane pores, washing away the powder adhering to the surface of the ceramic membrane 19, further preventing the ceramic membrane 19 from clogging and thus ensuring water flow capacity. This invention is also equipped with a spray pump 12, which, through the spray pump 12 and the fourth pipe 13, can eliminate bubbles generated by aeration during operation.

[0031] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
