Problems solved by technology

[0002] Usually, the adjustment and control of the flatness of the filter disc assembly of the rotary vacuum filter relies on a sample ruler, a level and a pad iron, that is, a sample ruler or a level is attached to the plane to be inspected, and the gap and level are observed. The defects of these leveling devices are relatively large. Many: (1) The inspection process is not rigorous, which will inevitably lead to missed inspections and re-inspections; (2) There is no unified benchmark for many gaps measured, which makes it difficult to adjust the gaps; (3) This method is difficult to use in production Control of flatness in process

Embodiment Construction

[0011] according to figure 1 As shown, the filter disc assembly is composed of a filter disc 1, a grid 2 and a screen 3, the grid 2 is placed on the filter disc 1 to hold the screen 3, and the filter disc assembly is supported by a retainer and a supporting wheel. When leveling the grid 2, the outer edge of the fan-shaped filter disc assembly is provided with two radially arranged level rulers 6, and the two ends of the level ruler 6 are connected with the vertical position regulator 14 and fixed on the fixed rod 15 to adjust the vertical position. The position of the regulator 14 on the fixed rod 15 can change the height of the level bar 6, and the flatness of the level bar 6 can be determined by a level. The level bar 6 is provided with a plurality of tensioners 8, and after the tensioner 8 tightens the level bar 6, the contour block 7 and the grid 2, the radial outer edge of the grid 2 is in the same plane, and then the Welded in filter disc 1. After removing the tensione...

Abstract

A method and apparatus for levelling the filter disc assembly of rotary-disc vacuum filter is disclosed. Two horizontal rules as the location reference are arranged along the radial direction of filter disk. When lattice is levelled, the equiheight cushion blocks are put between lattice and horizontal rule and a pull device is used to bind said horizontal rule, cushion blocks and lattice closely. Finally, the lattice in a same horizontal level is welded in filter disk. Its advantages are high correctness, speed and precision.

Description

technical field [0001] The invention relates to a leveling method and a leveling device applied to a filter disc assembly of a rotary vacuum filter. Background technique [0002] Usually, the adjustment and control of the flatness of the filter disc assembly of the rotary vacuum filter relies on a sample ruler, a level and a pad iron, that is, a sample ruler or a level is attached to the plane to be inspected, and the gap and level are observed. The defects of these leveling devices are relatively large. Many: (1) The inspection process is not rigorous, which will inevitably lead to missed inspections and re-inspections; (2) There is no unified benchmark for many gaps measured, which makes it difficult to adjust the gaps; (3) This method is difficult to use in production Control of flatness in the process. Contents of the invention [0003] The invention provides a leveling device for adjusting the grid plane of a rotary vacuum filter and checking the flatness of a screen...
