Description

Basket filter

[ field of technology ]

The utility model relates to the technical field of basket filters, in particular to the technical field of basket filters.

[ background Art ]

Lime slurry is used in the rotary spray semi-dry process, because the solubility of lime is low, lime particles in the slurry are in a suspended state, and the slurry needs to be filtered after the lime slurry is prepared so as to remove larger particles in the lime slurry, so that an atomizer is not blocked. The filtering modes commonly used in engineering are mainly two types of vibrating screens and basket filters.

The vibrating screen has a larger filtering area, and coarse particles in the slurry can be well filtered, but because the vibrating screen is large in size, occupies a larger space and is expensive, some owners do not adopt the filtering equipment for saving money.

The standard basket filter has smaller size, low cost, certain filtering effect and wide application.

However, the existing basket type filter is designed into a pluggable form due to the need of overhauling and cleaning the filter element, the filter element is placed on an elliptical support ring plate in a filter cylinder body during normal use, the plane of an elliptical annular pressing plate of the filter element is tightly attached to the plane of the elliptical support ring plate in the filter cylinder body, and the filter cylinder body of the filter element separates the filter into two spaces: an inlet end for the material and an outlet end for the material. The stainless steel wire mesh of the common filter element can select proper mesh number according to the size of solid impurity particles to be filtered, so that normal use is ensured, and the purposes of blocking and filtering the solid impurities are achieved. A certain gap exists between the contact surfaces of the elliptical annular pressing plate of the filter element and the elliptical supporting annular plate in the filter cylinder body, the use effect of the filter is not basically affected when large-particle solid impurities are blocked and filtered, but when tiny solid impurity particles such as anti-disproportionation resin which is blocked, filtered and worn and broken pass through the annular gap easily, so that the basket filter is partially disabled.

In order to solve the problem, application number 202221335110 discloses X a basket filter, in this technical scheme, set up elastomeric element between first backup pad and first clamp plate, elastomeric element can seal the gap between first backup pad and the first clamp plate, then connect and fix first backup pad, elastomeric element and first clamp plate through connecting element to reach the technological effect in gap between sealed first backup pad and the first clamp plate, and then reach the technological effect that improves basket filter's leakproofness.

Although the above-mentioned product possesses certain sealed effect, still there are some defects, in above-mentioned product, when connecting piece bolt is twisted, is the upper and lower direction lift, and the basket is also the upper and lower direction lift, and the bolt appears not hard up very common thing in the use, consequently once the bolt is not hard up, the basket just can reciprocate, and then just can not reach sealing state between first backup pad and the first clamp plate, therefore in above-mentioned product, the junction leakproofness of basket and filter casing is very unstable.

Therefore, in order to provide a stable and good sealing property at the junction of the basket and the filter housing, it is necessary to provide a basket filter.
