Field of the Invention The present invention relates to a method for manufacturing a dust-collecting honeycomb filter used for removing dust and the like in a gas to be treated, and more particularly, to manufacturing a flanged filter having a flange at one end of the filter. About the method.

化するために使用されている。2. Description of the Related Art A honeycomb filter is a dust collecting filter for removing dust and the like in a gas to be treated, and recovers products from a high-temperature gas in a wide range of fields such as chemical, electric power, steel and automobile-related industries. Or used to purify exhaust gas.

It has a structure sealed alternately every time. According to the filter 1, since the gas to be treated including dust and the like is sent into the cell 3 from the inlet side B, dust and the like larger than the pore diameter of the porous body are trapped in the pores of the cell wall 2. Only the gas component permeating the wall 2 can be recovered from the outlet side C as a processed gas.

Hereinafter, such a filter is referred to as a “flanged filter”.) Since the flanged filter 21 can hermetically join the flange 25 to the mounting frame 27 via the seal member 26, it is possible to prevent mixing of the gas to be processed and the processed gas.

And a molded body of the flange portion (that is, an unsintered body) are joined by a joining material made of unsintered powder of the same material as the main body and the flange. It has been manufactured by a sintered body-sintered body joining method of joining a sintered body of a flange portion with a joining material made of unfired powder of the same material as the main body and the flange.

う面で問題があった。However, the above-mentioned manufacturing methods have problems in manufacturing or in the quality of manufactured filters, and none of these methods can be said to be sufficient. For example, in the integral molding method, it is difficult to continuously mold a complex-shaped product such as a flanged filter, so that the molding process is complicated, and there is a problem in that production efficiency is low.

On the other hand, in the sintered body-sintered body bonding method, since unfired powder is used as a bonding material, there is a problem that cracks occur in the main body and the flange due to shrinkage of the bonding material itself.

A molded article-molded article joining method of directly joining と and と without using a joining material is also conceivable. However, it is difficult to directly join molded bodies that are inferior to the sintered body in terms of handling properties. In addition to low production efficiency, when firing failure such as cracks occurs in only one of the main body and the flange. However, there is a disadvantage that the difficult bonding step is completely wasted.

の製造方法について詳細に説明する。BEST MODE FOR CARRYING OUT THE INVENTION According to the production method of the present invention, the sintered body of the main body portion and the sintered body of the flange portion are formed by mixing a sintered powder of ceramic and an unfired powder of the same material as the main body and the flange at a predetermined ratio. It is characterized by joining with the joining material included in the above. According to such a manufacturing method, it is possible to prevent the occurrence of cracks in the main body and the flange or the generation of a gap at the joint between the main body and the flange, and it is possible to further improve the production efficiency. Hereinafter, the production method of the present invention will be described in detail.

らである。The manufacturing method of the present invention employs a sintered body-sintered body joining method of joining the sintered body of the flange part to the sintered body of the main body part with a joining material of the same material as the main body and the flange. In the sintered body-sintered body joining method, since the main body part and the flange part are formed separately, the forming process is simple and it is possible to improve the production efficiency, and the flange part is already fired. Therefore, cracks do not occur in the main body or the flange due to shrinkage of the flange portion during firing.

る。Furthermore, the sintered body-sintered body joining method joins sintered bodies having excellent handling properties, so that they can be easily joined to each other and production efficiency can be improved. Since the parts are separately fired and then joined, there is an advantage that the joining step is not wasted due to poor firing of either the main body or the flange.

は、本体及びフランジと同材質のセラミックの焼成粉末
と未焼成粉末とが重量比６０：４０〜９５：５の範囲内
で含まれる接合材を使用して接合を行うこととした。However, in the conventional sintered body-sintered body bonding method, since a bonding material made of unfired powder (such as a paste of unfired powder) is used as the bonding material, the firing material shrinks due to firing shrinkage of the bonding material itself. There has been a problem that cracks occur in the main body and the flange. Therefore, in the manufacturing method of the present invention, the joining is performed using a joining material in which the fired powder of ceramic and the unfired powder of the same material as the main body and the flange are included in a weight ratio of 60:40 to 95: 5. I decided to do it.

ジにクラックを生ずるため好ましくない。The reason why the ceramic contained in the bonding material is made of the same material as the main body and the flange is to make the thermal expansion coefficients of the main body and the flange and the bonding material coincide with each other. The reason for this is to prevent firing shrinkage of the bonding material while securing a sufficient bonding force. That is, if the weight ratio of the fired powder exceeds 95%, the bonding strength is reduced and a gap is formed between the main body and the flange, which is not preferable. It is not preferable because cracks occur in the main body and the flange due to shrinkage during firing.

Also includes ceramic raw material powder synthesized by firing. For example, in the case of cordierite, the raw material powder such as talc, kaolin, alumina, silica and the like corresponds to the “green powder” in the present invention. Each of these powders has a particle size of several tens to 100.
Use a material of about μm.

It is also possible to prepare a fired powder by pulverizing the unfired powder and pulverizing a defective product (a cracked product or the like) in the firing step. Such a method is preferable in that the raw material cost can be reduced.

However, it is preferable to use cordierite in that the firing shrinkage is small.

For example, if 25% to 30% by weight of water is added to the total weight of the ceramic, the joining material can be formed into a pellet, and if 40% by weight or more of water is added, the joining material can be formed into a slurry. Also,

It is also possible to add a certain amount of an organic binder (for example, a water-soluble polymer or the like).
