For addressing the above problem, the technical scheme that the utility model adopts is as follows:
A kind of cartridge filter that is conducive to improve ash-removal effect, comprise cylindrical shell, be arranged on cylinder top end cap, be arranged on the cylindrical shell and be positioned at the filter chamber of end cap below, in this filter chamber filter core is installed, be provided with the Venturi tube for the supplied gas turnover on the described end cap; This Venturi tube comprises the tube chamber section of shrinking, and the bore of the upper tube chamber mouth of this contraction tube chamber section is greater than the bore of lower tube chamber mouth.
Described contraction tube chamber section is round table-like.
Described Venturi tube also comprises the trunnion chamber section that is positioned at contraction tube chamber subordinate side, and this trunnion chamber section is cylindric.
Described end cap and Venturi tube are one-body molded.
Cylindrical shell comprise below the end cap and be sleeved on the upper viscose glue lid of Venturi tube outside, at the lower viscose glue lid below the upper viscose glue lid, be connected between viscose glue lid and the lower viscose glue lid also cylindrical interior looped network; Described filter chamber by upper viscose glue cover, lower viscose glue lid consists of with the lateral wall of interior looped network.
Form diversion cavity between the madial wall of described lower viscose glue lid, end cap and interior looped network, described contraction tube chamber section is communicated with diversion cavity.
Also be set with sealing ring on the described end cap, be provided with the groove for the card setting-in on the sealing circle.
Compared to existing technology, the beneficial effects of the utility model are:
Compare with existing cartridge filter, the utility model is by adopting the design of Venturi tube, and in the situation of cylindrical shell size constancy, the larger advantage of cross-sectional area that it can keep filter chamber also can enlarge the bore of upper tube chamber mouth, thereby improves the effect of pulse dust cleaning; And by utilize shrinking tube chamber section, but the flow velocity of acceleration pulse air-flow further improves the effect of pulse dust cleaning; In addition, it is simple in structure, cost of manufacture is lower, is conducive to promote the use of.
