Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of porcelain insulator slurry processing, in particular to a porcelain insulator slurry filter pressing device and method based on double pressure. BACKGROUND

[0002] As an important component in the power system, the quality and performance of the porcelain insulator are directly related to the safe and stable operation of the power system. In the manufacturing process of the porcelain insulator, slurry filter pressing is one of the key links, which needs to remove excessive water in the slurry through a filter pressing device to make mud cakes for the next process. At present, the widely used filter pressing device is usually a plate and frame filter pressing equipment. Although this equipment can remove excessive water in the porcelain insulator slurry, it still has the following defects in use:

[0003] The traditional plate and frame filter pressing equipment adopts a hydraulic filter pressing dewatering method, that is, the mud water is discharged by pushing forward through a hydraulic telescopic device. However, the stress of each filter plate is uneven, which leads to large difference in slurry water content, affecting the quality of the slurry. In addition, the use of single hydraulic filter pressing makes it difficult to pressurize the hydraulic equipment in the later stage due to the certain hardness of the slurry in the filter cloth, which easily causes damage to the hydraulic equipment, thereby affecting the production cycle and the quality of the slurry.

[0004] After the slurry is removed to form mud cakes, the mud cakes are easy to stick to the filter cloth. Therefore, after the filter plate is opened, a large amount of time is spent on separating the two by manual labor, which is high in labor intensity and troublesome to use.

[0005] After the mud cakes are separated from the filter cloth, some filter residue particles are adhered to the filter cloth. The surface residue needs to be cleaned every time after work, and at present, the cleaning is usually performed by manual flushing with a water gun, which is low in cleaning efficiency and poor in cleaning effect.

[0006] Therefore, we propose a porcelain insulator slurry filter pressing device and method based on double pressure. SUMMARY
