ィルタの構造に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a honeycomb body in which a large number of cells are defined by porous thin walls, in which the ends on the inlet side and the outlet side of adjacent cells are alternately arranged. The present invention relates to the structure of a particulate filter closed with a plugging material.
［従来の技術］ かかるパーティキュレイトフィルタは知られている（例
えば実開昭60−70709号公報）。[Prior Art] Such a particulate filter is known (for example, Japanese Utility Model Laid-Open No. 60-70709).

の符号11は補助熱源、T2はパーティキュレイト燃焼温度
である。In such a known particulate filter,
When the temperature is raised to the combustion temperature of the particulates trapped in the filter by the auxiliary heat source and the particulates are burned and removed to regenerate the filter, the central part on the outlet side of the filter occurs during regeneration on the upstream side of the filter. Heat is transmitted,
In addition, since heat radiation to the outer periphery is poor, as shown in FIGS. 3 and 4, the inlet side center portion and the center portion of the filter 1A are lower than the filter melting loss and crack generation temperature T 1 (for example, 1000 ° C.). On the other hand, there is a problem that the center portion on the outlet side becomes high and the portion is melted and cracked. Reference numeral 11 in the figure is an auxiliary heat source, and T 2 is a particulate combustion temperature.
これに対し本出願人は実願昭63−6075号において、セル
通過面積を中心部で小さく、外周に近付くほど大きくな
るように形成し、中心部のパーティキュレイト捕集量を
少なくして再生時の中心部の発熱量を減少し、上記不具
合を解消する技術を提案している。On the other hand, the applicant of the present invention, in Japanese Patent Application No. 63-6075, reproduces by making the cell passage area small at the center and larger as it gets closer to the outer periphery, and reducing the amount of collected particulates in the center. At the same time, a technique is proposed that reduces the heat generation amount in the central portion and solves the above problems.
この提案技術自体は有効なものであるが、しかし、セル
の形状及び目封じ態様が複雑で製作が面倒である。This proposed technique itself is effective, however, the shape of the cell and the manner of plugging are complicated and the production is troublesome.
また実開昭59−67516号公報には出口側中央部に上流側
に向う凹部を設けたパーティキュレイトフィルタが開示
されているが、ハニカム状のセラミック本体を連続して
製造することが困難であり、組立性が悪い。Further, Japanese Utility Model Laid-Open No. 59-67516 discloses a particulate filter in which a concave portion facing the upstream side is provided in the central portion on the outlet side, but it is difficult to continuously manufacture a honeycomb-shaped ceramic body. Yes, assembly is poor.

閉塞部の長さは中心部が最も長く周辺部になるにしたが
って、順次短かくなるパーティキュレイトフィルタが開
示されている。しかしながらかかる公知技術では目封じ
材の長さが異なるために作業性が悪い。Further, Japanese Utility Model Laid-Open No. 61-10917 discloses a particulate filter in which the length of the closed portion at the outlet portion becomes longer as the central portion becomes longer and becomes closer to the peripheral portion. However, in such a known technique, workability is poor because the length of the plugging material is different.
［解決しようとする課題］ したがって、本考案の目的は製作や組立が容易であり、

ティキュレイトフィルタの構造を提供するにある。[Problems to be solved] Therefore, the object of the present invention is to easily manufacture and assemble,
In addition, it is to provide a structure of a particulate filter that can prevent melting damage and cracks at the outlet side center part.

In the structure of the blocked particulate filter, a plurality of plugging materials (7) having the same length are enclosed at the outlet side of the cell in the central portion up to the substantially central portion, and the cylindrical non-collecting portion (9a) is formed. Has been formed.

ックの発生が防止される。[Explanation of action and effect] In the non-collecting portion formed by the cylindrical cavity or the plugging material,
Particulates are not captured. Therefore, when the particulates are burned and removed, the heat of burning the particulates is not generated in the non-collection portion, so that the temperature rise of the portion is suppressed. As a result, the filter is prevented from melting and cracking.
そして本考案では、セルが長さ方向で同じであるから製
造がしやすく、また目封じ材も２種類用意しておけばよ
く、組立が容易である。In the present invention, since the cells are the same in the length direction, it is easy to manufacture, and it suffices to prepare two kinds of plugging materials, and the assembly is easy.
［実施例］ 以下図面を参照して本考案の実施例を説明する。[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.
第１図において、パーティキュレイトフィルタ1aは、多

は、目封じ材６及び７で交互に閉塞されている。中心部
のセル3e、3gの出口側の目封じ材7aを、セルの略中央部
まで封入して円柱状の非捕集部9aが形成されている。In FIG. 1, the particulate filter 1a is formed in a honeycomb-like body in which a large number of cells 3a to 3n (reference numeral 3 is used when collectively referred to) are defined by the porous thin wall 2. Inlet and outlet openings 4 and 5 of these cells 3
Are alternately closed by the plugging materials 6 and 7. A cylindrical non-collecting portion 9a is formed by enclosing the plugging material 7a on the outlet side of the cells 3e and 3g in the central portion up to the substantially central portion of the cell.
したがって、排気ガスのパーティキュレイトは、非捕集
部9aには捕集されない。そのため、補助熱源11（第３
図）によりパーティキュレイトを燃焼して除去する際、
非捕集部9aではパーティキュレイトの燃焼は行われな
い。それ故にフィルタの溶損、クラックの発生を防止で
きる。Therefore, the particulate matter of the exhaust gas is not collected by the non-collection unit 9a. Therefore, the auxiliary heat source 11 (3rd
Fig.) When burning and removing the particulates,
Particulates are not burned in the non-collecting section 9a. Therefore, it is possible to prevent the filter from melting and cracking.
したがって、第２図に示すように、入口側の温度は低
く、出口側中心部も入口側中心部、中央部と同様
にフィルタ溶損、クラック発生温度T1以下に抑えられ
る。また、目封じ材7aを封入する構造により、強度を強
くすることができる。Therefore, as shown in FIG. 2, the temperature on the inlet side is low, and the central portion on the outlet side can be suppressed to the melting temperature of the filter and the crack generation temperature T1 or less like the central portion and the central portion on the inlet side. Further, the structure in which the plugging material 7a is enclosed can increase the strength.
［考案の効果］ 本考案によれば、高温となってフィルタの溶損やクラッ
