Description

Technical Field

[0001] The utility model belongs to the technical field related to filtering equipment, and particularly relates to a novel sintered mesh filter element. Background Art

[0002] Sintered mesh filter element is a filter material made of multiple layers of stainless steel wire mesh through special lamination pressing and vacuum sintering. This filter element has high mechanical strength and overall rigidity, as well as a stable mesh structure. The mesh holes of each layer of the sintered mesh filter element are interlaced to form a uniform filtering structure, which is suitable for a variety of filtering occasions. They usually have good filtering accuracy, filtering impedance, wear resistance, heat resistance and processability, but it still has the following disadvantages in actual use:

[0003] During the filtration process of the sintered mesh filter element, in order to further increase the filtering effect of the filter element, a filter sleeve is added inside to further filter the liquid. During the filtration process, the filter sleeve needs to be used for filtration. During the filtration process, the filter sleeve needs to be replaced after the effect of long-term use decreases. The replacement operation is relatively complicated.

[0004] When the sintered mesh filter element is working, the filter sleeve therein directly adopts the corresponding structure for filtering. However, when facing the filtering requirements of different liquids and different pressures, the filter sleeve with higher precision needs to be tensioned at different pressures. During the operation, it is not convenient to adjust the tension of the internal filter sleeve. Utility Model Content

[0010] Furthermore, a limiting plate is fixed on the inner wall of the limiting sleeve corresponding to the position of the limiting block, the limiting block is movably connected in the limiting sleeve, the limiting plate is arranged on the top of the limiting block, and the limiting sleeve limits the limiting block through the limiting plate, thereby further limiting the limiting block.

[0011] Furthermore, a rotating block is fixed at the top center of the top plate, and through holes are opened in the rotating block and the inner center of the top plate. Long bolts are threadedly connected in a circular array inside the top plate outside the rotating block, and the bottom ends of the long bolts are rotatably connected to the top of the support plate.

[0014] The utility model solves the problem that it is not convenient to replace the internal filter sleeve of the sintered mesh filter element by arranging the support sleeve, the limiting sleeve, the inner filter sleeve and the upper fixing ring. When the inner filter sleeve needs to be removed, the rotating block is directly rotated to move the limiting block on the peripheral side of the support disk from under the limiting plate in the limiting sleeve, and the inner filter sleeve can be pulled out. The top plate is held, the support disk is placed in the upper fixing ring and then lowered into the limiting sleeve until the support disk is supported on the top of the support column and the top plate is movably connected to the upper fixing ring. The rotating block is then rotated to drive the inner filter sleeve and the support disk to rotate, so that the limiting block on the peripheral side of the support disk enters under the limiting plate in the limiting sleeve, so that the inner filter sleeve is well supported and restricted on the support column, making it more convenient to replace the internal filter sleeve of the sintered mesh filter element.
