Description

Technical Field

[0001] The utility model relates to the technical field of hydrolyzate solid particle filters, in particular to a hydrolyzate filtering device used in a hydrolyzer. Background Art

[0002] The hydrolyzate filter device of the hydrolyzer has a wide range of applications. When the filter device is in operation, after the liquid passes through the cylinder and enters the filter basket, the solid impurity particles are blocked in the filter basket, while the clean fluid passes through the filter basket and is discharged from the filter outlet, and the solid particles that do not pass through are discharged from the filter from the bottom outlet. Since the cleanliness and integrity of the filter element will affect the filtering effect, the filter element needs to be cleaned frequently.

[0003] To clean the existing filters, it is necessary to open the top cover of the filter, then take out the filter element and clean the internal particles. For hydrolyzates with higher solid particle content, the filter element needs to be cleaned frequently, which will affect the filtration efficiency. Moreover, the filter element in most filters is fixed by top boss fixation or bottom support fixation. Since it is fixed at one end, it is easy to cause unstable fixation of the filter element, which will affect the sealing between the filter element and the fixed structure, affect the filtration effect, and even cause the filter element to fall off, making the filter ineffective.
