Description

Candle type filter

Technical Field

The utility model relates to a filtration equipment technical field, especially a novel candle type filter.

Background

The candle filter is a filtering and adsorbing device used in the industrial production of electroplating, chlor-alkali industry, ceramics, pharmacy, sugar making, wine making, water treatment and the like, and mainly functions to recover and filter solid substances in liquid discharged by production and the like (for example, diatomite impurities in the liquid are filtered and reused in beer production and the like, but not limited to). The candle filter has the following advantages: the filtering capacity is high, the filtered filter cake can be washed, dried and reused, the cost is saved, and the economic benefit is good; the machine shell is sealed, safe and free of leakage, the environment is clean and free of pollution, and one-time complete filtration can be achieved.

The general structure of the existing candle type filter comprises a tank body, a filter element, a water pump and other parts. When the filter core is in work, sewage to be filtered is pumped out from the sewage tank by the water pump and then pumped into the tank body, enters the filter core through the filter core micropores in the tank body, and then flows out from the clear liquid pipe communicated with the upper end in the filter core and enters the clear liquid tank. After the filtration is finished, in order to filter the residual liquid in the tank body, the positive air blowing port at the upper end of the tank body is opened, and then compressed air enters the tank body, and the residual liquid in the tank body is discharged from the clear liquid pipe after being filtered by the filter element under the action of the compressed air. After the residual liquid in the tank body is filtered, a backflushing valve connected with the clear liquid pipe in parallel is opened, compressed air is discharged outside the filter element through the inside of the filter element, and then filter cakes (filter cakes are formed after the filter residues are too much) adhered to the outer surface of the filter element and filter residues fall out of the lower end outside the tank body (a pneumatic valve at the lower end of the tank body is opened in advance) are washed out.

The conventional candle type filter is limited in liquid filtering area due to the fact that only one filter element is arranged in the conventional candle type filter, and the whole device cannot work normally when the filter element is partially or completely blocked. Still what is, the filter core structure of present candle filter is generally that the interval is trompil from top to bottom at the outside end of a pipeline, then the filter cloth constitutes at pipeline outside end suit, like this when need get rid of jar internal residual liquid (usually full jar) to the internal input of jar is blowing compressed air, in fact compressed air major part can be followed the trompil of filter core upper end and passed through the liquid pipe and discharged, can lead to the residual liquid in the jar body and mostly can't obtain filtering discharge from this, follow-up a large amount of unfiltered residual liquid can bring unnecessary loss (when needing to retrieve useful filter cake to discharge along with the filter cake for the user (when needing to retrieve useful filter cake), or increase the complexity of equipment (for example input residual liquid into the dirty water tank through equipment pipeline etc. and reprocess), this is also the main problem that current candle filter exists. Based on the above, the candle type filter which has a large filtering area, can effectively prevent the filter element from being blocked and can filter and treat all the residual liquid in the tank body as much as possible is especially necessary.

SUMMERY OF THE UTILITY MODEL

In order to overcome current candle filter because of the structure limit, there is filter core filtration area little relatively, take place easily to block up the shortcoming that leads to filtering the core performance variation, and can not effectively carry out the drawback of handling with jar internal surplus liquid, the utility model provides a multiunit combination formula filter core has been provided, multiunit combination formula filter core has improved filtration area, has prevented that single filter core filtration performance variation or has blockked up the shortcoming that leads to the whole unable normal work of equipment after, every filter core has inner tube and outer tube etc. liquid flows in from the outer tube upper end during filtering, and the inner tube lower extreme flows into in the inner tube, and flows out the clear solution pipe from the inner tube upper end, when filtering jar internal surplus liquid very much, can guarantee jar internal upper and lower extreme liquid all to obtain the novel candle filter of filtering and discharge as far as possible.
