Detailed description of the invention
Fig. 1, filter shown in 2, it comprises horizontally disposed filter core mounting board 1, this filter core mounting board 1 is spaced several filter core 2 perpendicular to filter core mounting board 1 is installed, these filter cores 2 are specially cemented iron Al intermetallic porous material tubulose filter core, one end of these filter cores 2 is arranged on described filter core mounting board 1 and the other end is arranged down, one Wen's anti-blowpipe 31 is also installed above filter core mounting board 1, the large end end face of this Wen's anti-blowpipe 31 is fixed on the upper surface of filter core mounting board 1, thus Wen's anti-blowpipe 31 and filter core mounting board 1 are fixed as one, the cavity 3 of Wen's anti-blowpipe 31 inside is mutually isolated by the space below described filter core mounting board 1 and filter core 2 and filter core mounting board 1, a main supporting plate 4 has also been horizontally disposed with below filter core mounting board 1, main supporting plate 4 is fixed in a relatively-stationary structure that (such as main supporting plate 4 is fixed in a cylindrical shell, cylindrical shell again by floor installation on the ground of factory), the elastic corrugated pipe support 5 be placed on the top of these filter cores 2 above-mentioned in its inner chamber is installed between main supporting plate 4 and filter core mounting board 1, the upper surface of elastic corrugated pipe support 5 is connected with the lower surface of filter core mounting board 1, the lower surface of elastic corrugated pipe support 5 is connected with the upper surface of main supporting plate 4, thus make filter core mounting board 1, Wen's anti-blowpipe 31 above filter core mounting board 1 and the filter core 2 on filter core mounting board 1 form one jointly can the movable component of elastic vibration relative to main supporting plate 4, the movable position limiting structure 6 that the scope of activities of movable component is controlled also is connected with between main supporting plate 4 and filter core mounting board 1.
As shown in Figure 2, the concrete mounting means of filter core 2 on filter core mounting board 1 is: the filter core installing hole on the upper end of filter core 2 and filter core mounting board 1 is sealed and matched, specifically, the upper end of filter core 2 is provided with a flange, the lower end of flange is a conical surface or sphere, there is the position of matching with this conical surface or sphere in filter core installing hole, and be provided with sealing gasket between the conical surface of flange or the sphere matching part corresponding on filter core installing hole, in addition, the compressing structure 8 for pushing down filter core 2 upper surface is downwards provided with above filter core mounting board 1, this compressing structure 8 can the adaptive adjustment according to the trickle change in location of filter core 2, compressing structure 8 specifically comprises pressing plate 81, pressing plate 81 is threaded connection part 82 and is fixed on above filter core mounting board 1, presser feet 83 is provided with between pressing plate 81 and filter core 2 upper surface, filter core 2 upper surface is pushed down in presser feet 83 bottom surface, seal washer is provided with between presser feet 83 bottom surface and filter core 2 upper surface, presser feet 83 top then with the pilot hole matched in clearance on pressing plate 81, the pod apertures 831 of conducting filter core 2 upper port and pressing plate 81 upper space is provided with in presser feet 83, the outer also cover of presser feet 83 have a pretension bottom pressing plate 81 and presser feet 83 between spring 84.
The working method of above-mentioned filter is: during filtration, is arranged in the gas to be filtered of filter core mounting board 1 underlying space by entering the cavity 3 of Wen's anti-blowpipe 31 after filter core 2 filtration and exporting from cavity 3 top, during blowback, blowback working gas to enter from the top of cavity 3 in Wen's anti-blowpipe 31 and moves downward after increasing flow velocity by Wen's anti-blowpipe 31, part blowback working gas acts on the top of filter core mounting board 1, bottom direction in the upper port that another part enters into each filter core 2 and towards filter core 2 is moved, finally act in the inside bottom surface of filter core 2, therefore, because filter core 2 and filter core mounting board 1 are all subject to downward pressure, thus the downforce in elastic corrugated pipe support 5 upper surface will be put on by filter core mounting board 1, force elastic corrugated pipe support 5 that further contraction distortion (upper surface of elastic corrugated pipe support 5 just carries the weight of movable component and makes elastic corrugated pipe support 5 shrink distortion before non-blowback) occurs, and reduce once the pressure of blowback working gas or disappear (at employing pulse backblowing working gas, the pressure of blowback working gas rapidly disappears), then will there is elastic recoil again in elastic corrugated pipe support 5, make whole movable component, relative to main supporting plate 4, elastic vibration occur thus.
As Fig. 1, as a kind of decision design of described movable position limiting structure 6, as shown in Figure 1, described movable position limiting structure 6 comprise many rhizospheres around elastic corrugated pipe support 5 peripheral intervals arrange and the column 61 on main supporting plate 4 is fixed in lower end, filter core mounting board 1 is provided with the guide hole matched with corresponding column 61 respectively, column 61 is positioned at above and below filter core mounting board 1 and is separately installed with upper limit baffle plate 611 and lower limit baffle plate 612.Above-mentioned movable position limiting structure 6 had both limited the radial motion of movable component, again by the surge motion control of movable component between upper limit baffle plate 611 and lower limit baffle plate 612, thus make elastic corrugated pipe support 5 substantially can only axial stretching, be more conducive to by carrying out deashing by elastic vibration.And when normal filtration, filter core mounting board 1 preferably contacts with upper limit baffle plate 611 or close.
For another example Fig. 1, because filter of the present utility model filter core 2 when blowback axial vibration can occur, and in order to collide between filter core 2 when preventing from vibrating, also further by unified for the lower end of described each filter core 2 be connected to one bottom on positioner 7, described bottom positioner 7 comprises supporting member 71 below filter core 2, be connected to pull bar 72 between filter core mounting board 1 with supporting member 71 and from supporting member 71 protrude upward and respectively with the backstay 73 that the lower end locating hole of corresponding each filter core 2 is suitable.Like this, by the location to each filter core 2, can avoid vibrating the adverse effect produced filter core 2.
In addition, consider and movable component is fully vibrated thus better deashing, the deflection of elastic corrugated pipe support 5 during blowback need be ensured.In the present embodiment, axial length and the filter core length ratio of described elastic corrugated pipe support 5 are preferably set to (0.15 ~ 0.4): 1, be set to further (0.2 ~ 0.3): 1, such as be set to 0.25:1, to guarantee that elastic corrugated pipe support 5 both can not contact the top of filter core 2 by gas to be filtered because of oversize and too much stop, also fully can ensure the deflection of elastic corrugated pipe support 5 during blowback simultaneously, make movable component reach desirable Oscillation Amplitude.
