Abstract
The utility model relates to a fixing structure of a filter core of a polyisobutene filter, which aims at providing the filter core which has the advantages of independent disassembly, assembly and replacement, convenient maintenance and high working efficiency. The fixing structure of a filter core of a polyisobutene filter provides the technical schemes that the filter core takes the shape of a column, external threads around the circumferential surface is arranged at the bottom end of the filter core, and internal threads which are matched with the external threads are arranged at a fixed hole on a bottom plate; and the filter core is spirally fixed on the bottom plate through the external threads; and a rubber gasket is assembled at the bottom end of the filter core.
Description
Technical field
The utility model relates to a kind of parts of filter, specifically is the filter core of polyisobutene filter.
Background technology
The polyisobutene structure of filter is to be arranged in parallel one group of filter core (more than ten filter core generally arranged) is installed in the closed inner chamber of filter body, material enters device cavity from finished product filter body outside under the effect of external force, and then the filtration of the filter screen of process tubulose filter core, draw arrival filter outside from the passage of filter core central authorities, finish the filtration treatment of finished product.
Existing filter element (as shown in Figure 2) is cylindrical, and its middle part is the stainless steel tube core 5 that is covered with perforate on the tube wall, and the outer circumference surface of stainless steel tube core is coating stainless steel filtering net 2, and filter screen divides two-layer, and internal layer is 40 order nets, and skin is 600 order nets.Circle edge (the P point place among Fig. 2) the electricity consumption solid welding that the two ends of stainless steel filtering net are inserted respectively in the bowl-shape edge of two ends pipe cap (pipe cap 1 and pipe cap 3) and filter screen is contacted with pipe cap is fixed.
The defective of this kind structure is that filter core can only disposablely use; When if filter screen has breakage, whole filter core all scrapped.Because filter is in quantity-produced state under the pressure, the filter screen breakage belongs to the conventional loss that is difficult to avoid; Because the filter screen breakage causes whole filter core to be scrapped, not only wasted resource (all the other position parts of filter core are still intact, also will together as waste product), and increased production cost (whole filter core is worth 1000 yuan /).
The utility model content
The purpose of this utility model is the deficiency that overcomes the above-mentioned background technology, and a kind of improvement of polyisobutene filter element is provided, and this filter core should have can repeat to change filter screen, characteristics easy to maintenance, and economizes on resources, reduces production costs.
The technical scheme that the utility model proposes is: the polyisobutene filter element, the filter screen, tube core two ends that comprise tube core, is coated on the tube core outer circumference surface be the pipe cap of filter screen fixedly, it is characterized in that described filter screen inserts between part and the pipe cap edge in the pipe cap edge to be connected by metallic tin.
Described metallic tin enters the slit between pipe cap and the filter screen along the whole edge of pipe cap when molten condition, be one with pipe cap and filter screen sealing and fixing after the cooling.
The utility model adopts metallic tin that filter screen is fixed on the filter core; Because the fusing point of metallic tin is low, so the filter core under changing needs only heating slightly metallic tin is melted, then replaceable filter screen also just becomes an intact filter core again with metallic tin is fixing once more, can repeat by that analogy, recycle.With respect to the cost (1000 yuan /) of whole filter core, filter screen only needs 200 yuan/.Change a filter core like this and just can save 700-750 yuan/Zhi Chengben, not only save cost but also increase work efficiency.In addition, because the low melting point characteristic of metallic tin, so maintenance activity is also convenient.
Description of drawings
Fig. 1 is a main TV structure schematic diagram of the present utility model.
Fig. 2 is the main TV structure schematic diagram of existing filter element.
The specific embodiment
Below in conjunction with embodiment shown in the drawings, the utility model is described in further detail.
As described in Figure 1, the polyisobutene filter element, the filter screen 2, tube core two ends that comprise tube core 5, is coated on the tube core outer circumference surface be the pipe cap 1 and the pipe cap 3 of filter screen fixedly, and described filter screen inserts the inboard, bowl-shape edge of pipe cap; Above structure is all identical with existing filter core.
The utility model has adopted the metallic tin connected mode to replace existing electric welding connected mode.Metallic tin inserts between part in the bowl-shape edge of pipe cap and the pipe cap edge filter screen and couples together.
Further, described metallic tin enters slit between pipe cap and the filter screen along the whole edge P of pipe cap when molten condition, after the cooling pipe cap and filter screen are fixed as one; So not only be connected firmly, also improved the sealing effectiveness of filter core.
Claims (1)
1, polyisobutene filter element, the filter screen (2), tube core two ends that comprise tube core (5), is coated on the tube core outer circumference surface be the pipe cap of filter screen (1,3) fixedly, it is characterized in that described filter screen inserts between part and the pipe cap edge in the pipe cap edge to be connected by metallic tin.
