Abstract
The utility model relates to a component of equipment in the technical fields such as chemical industry and pharmacy, in particular to a filter cartridge for preventing a filter screen from falling. The filter cartridge comprises an internal filter cartridge supporting member and an external filter screen, wherein the filter cartridge supporting member is of a cylindrical structure and is provided with leakage holes; the filter screen is of a cylindrical structure and is sleeved outside the filter cartridge supporting member; the filter cartridge is characterized in that the two ends of the filter cartridge supporting member are provided with thinning structures, threads are arranged outside the thinning structures, and the thinning structures are provided with bowl-shaped pressing members which are identical to the threads; or convex structures are arranged on the filter cartridge supporting member close to the two ends, threads are arranged outside the convex structures, bowl-shaped pressing members which are identical to the threads are arranged outside the convex structures, and rubber rings are arranged inside the pressing members; the filter cartridge has the advantages of low probability of falling of the filter screen, durability and convenience in replacement.
Description
Technical field
The utility model relates to the parts, particularly a kind of filter core of the technical field equipment such as chemical industry, pharmacy.
Background technology
On filter, be provided with filter core, filter core comprises inner filter core support member and outside filter screen, and filter core support member is columniform structure, on filter core support member, has weepage holes, and filter screen is tubular construction, and filter screen entangles outside filter core support member; In prior art, at filter core support member two ends, have draw-in groove, filter screen two ends fasten rope, and rope is fastened in draw-in groove fixedly filter screen, and such filter core has filter screen and easily comes off, the normal shortcoming of using of impact.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned shortcoming, the filter core that provides a kind of filter screen difficult drop-off, long-lived anti-filter screen to come off.
The technical solution of the utility model is to realize like this, the filter core that anti-filter screen comes off, comprise inner filter core support member and outside filter screen, filter core support member is columniform structure, on filter core support member, has weepage holes, and filter screen is tubular construction, filter screen entangles outside filter core support member, it is characterized in that: there is the structure of attenuating at described filter core support member two ends, there is screw thread in the structure that attenuates outside, has casting die bowl-shape, that coincide screw thread in the structure that attenuates.
Further say, there is rubber ring casting die inner side.
Or, the filter core that anti-filter screen comes off, comprise inner filter core support member and outside filter screen, filter core support member is columniform structure, on filter core support member, has weepage holes, and filter screen is tubular construction, filter screen entangles outside filter core support member, it is characterized in that: described filter core support member has bulge-structure near two ends, there is screw thread in bulge-structure outside, bulge-structure have outward bowl-shape, coincide screw thread casting die.
Further say, there is rubber ring casting die inner side.
Technique effect of the present utility model is: such filter core have filter screen difficult drop-off, durable in use, change advantage easily.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model the first situation.
Fig. 2 is the structural representation of the utility model the second situation.
Wherein: 1, filter core support member 2, filter screen 3, the structure that attenuates 4, rubber ring 5, bulge-structure 6, casting die.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1 and Figure 2, the filter core that anti-filter screen comes off, comprise inner filter core support member 1 and outside filter screen 2, filter core support member 1 is columniform structure, on filter core support member, has weepage holes, and filter screen is tubular construction, filter screen entangles outside filter core support member, it is characterized in that: there is the structure of attenuating 3 at described filter core support member two ends, there is screw thread in the structure that attenuates outside, in the structure that attenuates, have bowl-shape, coincide screw thread casting die 6.
Further say, there is rubber ring 4 casting die inner side.
Or, the filter core that anti-filter screen comes off, comprise inner filter core support member 1 and outside filter screen 2, filter core support member is columniform structure, on filter core support member, has weepage holes, and filter screen is tubular construction, filter screen entangles outside filter core support member, it is characterized in that: described filter core support member has bulge-structure 5 near two ends, there is screw thread in bulge-structure 5 outsides, bulge-structure have outward bowl-shape, coincide screw thread casting die 6.
Further say, there is rubber ring 4 casting die inner side.
