Abstract
The invention relates to an automatic sweeping filter, which comprises a filter upper cover and a filter base, wherein the filter upper cover is provided with an air inlet and an air outlet; the inside of the filter base is provided with a circular filter core fixedly connected with the filter upper cover; a cavity formed between the filter base and the filter core is communicated with the air inlet; a cavity formed between the filter core and a support base is communicated with the air outlet; the upper part of the cavity between the filter base and the filter core is provided with an air dispersing cover; after sample gas enters the filter, the air dispersing cover can evenly disperse the sample gas, so that the sample gas can be evenly blown to the surface layer of the filter core, and dust and impurities on the surface layer of the filter core can be automatically swept. The filter has the advantages of automatic sweeping and convenient use.
Description
Technical field
The present invention relates to a kind of self-cleaning filter, specifically, relate to a kind of a kind of self-cleaning filter that sample gas is filtered when being applicable to the chemical industry analytical gas.
Background technology
In chemical industry, need measure in real time gas, and often contain a certain amount of dust and impurity in the tested gas, sample gas is entering before the sensor, usually all filter through filter earlier, it is of a specified duration that but present filter uses, will be at the surface aggregation of filter core a large amount of dust and impurity, and filter results in blockage, influence the degree of accuracy of sensor, cause measurement result to produce deviation, need regular dismounting filter cleaning and filtering, use inconvenience.
Summary of the invention
The problem to be solved in the present invention is at above problem, and a kind of easy to use, a kind of self-cleaning filter that can clean filter core automatically is provided.
For achieving the above object, the technical solution adopted in the present invention is: a kind of self-cleaning filter, this filter comprises filter cover and filter base, filter cover has air inlet and gas outlet, be provided with the annular core of fixedlying connected in the filter base with filter cover, the filter base is communicated with air inlet with cavity between the filter core, and filter core is communicated with the gas outlet with cavity between the supporting seat, and it is characterized in that: the top of cavity is provided with exhaust hood between described filter base and the filter core.
A kind of technical scheme of optimization, all drains of the bottom of described filter base.
A kind of concrete prioritization scheme is provided with the O RunddichtringO between described filter base and the filter cover.
Another kind of concrete prioritization scheme is provided with sealing gasket between described filter core and the filter cover.
The present invention adopts technique scheme, after sample gas enters filter, exhaust hood disperses sample gas equably, make sample gas can blow on the filter core top layer equably, automatically cleaned dust, the impurity on filter core top layer, the impurity that purges flows away from the bypass drain, plays the effect from cleaning, and is very easy to use.
The invention will be further described below in conjunction with drawings and Examples.
