Description

(54) FILTER

I

The invention relates to periodic replenishment, especially of crystalline precipitates, which, after filtration, require thorough and uniform washing using a minimum amount of industrial liquid, and can be used in the chemical and other industries.

Lime filter for periodic filtering, including vertical shchritridnyh filter elements placed symmetrically in the horizontal section of the filter, each filter element having a nozzle located in the bottom of the filter 1.

A disadvantage of the known filter is that it is possible to obtain a hydrogen sludge filter that fills the fully horizontal cross section of the filter and removes the entire amount of the matte solution and industrial liquid.

The purpose of the invention is to carry out periodic filtration with varying surface filtration.

The goal is achieved by the fact that in the filter for periodic filtering, including

Each vertical filter element, located symmetrically in the horizontal section of the filter, has filter elements installed at different levels in height, with some of the filter elements mounted vertically, and some of the movable diaphragm valves. mi placed at their height.

Slot cartridges are used as filter elements in an amount of 0.5–3 per 1 m of the horizontal horizontal section of the filter. In addition, the filter siabzhei and outdoor heating rubapsoy.

FIG. 1 schematofso image filter, vertical section; in fig. 2 - filter elements placed in horizontal section of the filter.

In the filter housing 1, vertical cylindrical filter elements 2 are installed with nozzles 3 placed in the bottom of the filter housing 1, on which the filters are installed 4. Part of the filter elements 2 is fixed and can be switched off

4, the part is movable, and the part of the fixed can be turned off by parts with the help of valves 5. On the case 1 there is an external heating jacket 6. In the upper part of the case 1 there are nozzles for introducing the mixture 7 and for 5 washing liquid 8. collector 9 for removal of the filtrate. A nozzle 10 located at the bottom of the bottom of the case serves to discharge the product. .ABOUT

The filter works as follows.

The filtered mixture is introduced into the filter from above through the pipe 7, it passes into the inside of the filtering elements 2, and the filtrate is discharged through the collector 9. The washing liquid enters 15 through the pipe 8 and the spraying device into the filter.

The product in the form of a filtered sludge forms on the outer surface of the filter elements 2, then after moving 20 or melting it is discharged through the nozzle 10,

The advantages of the proposed filter include the simplicity of the design and its complete tightness, the ability to completely and uniformly flush the entire volume of filtered sludge with a minimum consumption of washing liquid, the possibility of using it to filter mixtures obtained by

crystallization, with different filtration characteristics.
