Embodiment

[0010] Example: a phosphogypsum flip filter in a phosphoric acid plant, with an effective filtration area of ​​102m 2 , the design capacity is P 2 o 5 150,000 tons per year, a total of 48 supporting wheels on the inner and outer tracks need to carry a weight of about 80 tons to operate. In order to extend the service life of the filter, reduce the maintenance cost, and improve the operating rate of the device, a new type of filter support wheel 1 as shown in Figure 1 was invented. It has two layers, the inner layer is carbon steel and the outer layer is polypropylene. There are intermeshing falcon grooves between the inner and outer layers. The outer diameter of the carbon steel part of the inner layer of supporting wheel 1 is 160mm, that is, the bearing thickness of carbon steel is 20mm, and the outer lining is a 220mm steel-lined polypropylene supporting wheel. The thickness of the acrylic layer is 30 mm; the supporting wheel 1 adopts a curved outer ring surface, which is ...

Abstract

A supporting roller for the tray turning-over filter is composed of internal layer made of carbon steel and external layer made of polypropene. The tenon-mortise structure is between said internal and external layers. Its axle hole has shoulder matched with the shoulder on axle. Its advantages are high running stability and high durability. Its assembling method is also disclosed.

Description

technical field [0001] The present invention is related to the filter, and more specifically, to the track supporting wheel of the flip filter. Background technique [0002] At present, the material of the supporting wheels of the flip filter is mostly carbon steel quenched and tempered, and the track material is 16Mn steel. The supporting wheel not only needs to load the weight of the material on the turning plate of the filter machine, but also the weight of the filter machine causes serious track wear. It has been measured that the wear rate of the track of a certain company’s turning plate filter machine reaches 6mm / year. According to this wear rate, the filter machine After 5 years of operation, the track has to be replaced. That will not only cost a lot of maintenance fees, but also because the maintenance takes time, the indirect loss is even greater. At the same time, since the rotating speed of the supporting roller is faster than that of the track, not only the t...
