Abstract
The utility model relates to a self-cleaning filter, which comprises an upper cover of the filter and a base of the filter, wherein the upper cover of the filter is provided with an air inlet and an air outlet. Further, a ring-shaped filter element fixedly connected with the upper cover of the filter is disposed inside the base of the filter, a cavity between the base of the filter and the filter element is communicated with the air inlet, a cavity between the filter element and a supporting base is communicated with the air outlet, and an upper portion of the cavity between the base of the filter and the filter element is provided with an air scattering cover. When sample gas enters into the filter, the air scattering cover uniformly scatters the sample gas to enable the sample gas to flow to a surface layer of the filter element, and then dust and impurity on the surface layer of the filter element can be cleaned automatically, thereby realizing automatically cleaning function and enabling the filter to be used conveniently.
Description
Technical field
The utility model relates to a kind of self-cleaning filter, specifically, relates to a kind of 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.
The utility model content
Problem to be solved in the utility model is at above problem, and a kind of easy to use, filter that can clean filter core automatically is provided.
For achieving the above object, the technical scheme that the utility model adopted 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, 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 utility model 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 utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model embodiment.
The 1-filter cover, 2-O RunddichtringO, 3-sealing gasket, 4-filter base, 5-supporting seat, 6-filter core, 7-exhaust hood, 8-air inlet, 9-gas outlet, 10, the 11-cavity, 12-drain
The specific embodiment
Embodiment, as shown in Figure 1, a kind of self-cleaning filter, the cylindrical filter base 4 that comprises the sealing of a filter cover 1 and an end, filter base 4 is threaded with filter cover 1, filter cover 1 has air inlet 8 and gas outlet 9, filter cover 1 is provided with supporting seat 5, supporting seat 5 is positioned at filter base 4, supporting seat 5 is provided with the filter core 6 of annular, filter base 4 is communicated with air inlet 8 with cavity 10 between the filter core 6, filter core 6 is communicated with gas outlet 9 with cavity 11 between the supporting seat 5, is provided with O RunddichtringO 2 between filter base 4 and the filter cover 1, is provided with sealing gasket 3 between filter core 6 and the filter cover 1, the top of cavity 10 is provided with the exhaust hood 7 of annular, all drains 12 of the bottom of filter base 4 between filter base 4 and filter core 6.
