Abstract
The utility model discloses a filtration core, which needs to solve a technical problem of providing a filter core having the advantages of high filtration precision, good anti vibration performance, high temperature resistance, good thermal force performance and long life-span, The technical proposal of the utility model is that, a filtration core comprises a filtration body, a cylinder-shaped metal sintered net filtration body which is uniformly arranged along the circumference, an end of the closed port of the filtration body is connected with a support plate with a gap, the open end of the filtration body is sealed and connected with the top cover hole. The metal sintered net filter body is sintered by at least three layers of metal. Four cylinder-shaped metal sintered net filter bodies are uniformly arranged along the circumference. The utility model can be used in diesel exhaust catcher, and in the filtration of industrial waste gas.
Description
Technical field:
The utility model relates to a kind of filter, particularly a kind of filter core.
Background technology:
Contain a large amount of soot particles in the tail gas of diesel vehicle or the industrial waste gas, need filter the realization environmental emission standard.What the used filter core of particulates in exhaust gas from diesel vehicle trap (filter) was maximum at present is honeycomb ceramic filter filter body, filter efficiency to soot can reach more than 90%, filter bodies such as also available foamed ceramics, ceramic honey comb, ceramic fibre braid are made filter core, because pottery filter body resistance to shock is relatively poor, especially use on diesel vehicle, the length of filter core is subjected to certain limitation, when heat is regenerated, its thermal stress is big, and is fragile.
Summary of the invention:
The utility model technical issues that need to address provide a kind of filter core, and its filtering accuracy height and resistance to shock and high temperature heat-resistant stress performance are good, long service life.The technical solution of the utility model is that a kind of filter core comprises the filter body, it is characterized in that: close mouth one end of the cylindrical metal sintering net filter body that is uniformly distributed along the circumference is connected with the gripper shoe that has breach, and the openend and the ending cover hole of above-mentioned filter body are tightly connected.Metal sintering net filter body has at least the three-layer metal sintering to form.Be uniformly distributed with four cylindrical metal sintering net filter bodies along the circumference.The utility model is owing to adopt metal sintering net filter body, thereby has resistance to shock compared with the prior art and the high temperature heat-resistant stress performance is good, the advantage of long service life.
Description of drawings:
Fig. 1 is a vertical section structure schematic diagram of the present utility model, and Fig. 2 is the right view of Fig. 1.
The specific embodiment:
In conjunction with above accompanying drawing the utility model is described in detail, in order to solve the resistance to shock and the elevated temperature heat stress performance of filter body, satisfy the requirement that exhaust gas from diesel vehicle filters and heat is regenerated, improve its service life, filter body 2 adopts complex sintered the forming of multiple layer metal net, and the volume circle is welded into tubular.In order to satisfy the requirement of filter area, filter core is made of four tubular filter bodies 2 of circumference uniform distribution, one port closed of filter body is connected with bracing frame 3 by screw-nut, hole on its openend and the end cap 1 is tightly connected, bracing frame 3 is open plate (referring to Fig. 2), make tail gas enter filter core and discharge by the filter body opening, the interception of the carbon granules in the tail gas on the wire netting surface, is realized environment protection emission through filter body mesh from indentation, there.
Claims (3)
1, a kind of filter core comprises the filter body, it is characterized in that: close mouth one end of the cylindrical metal sintering net filter body that is uniformly distributed along the circumference is connected with the gripper shoe that has breach, and the openend and the ending cover hole of above-mentioned filter body are tightly connected.
2, a kind of filter core as claimed in claim 1 is characterized in that: metal sintering net filter body has at least the three-layer metal sintering to form.
