The existing honeycomb ceramic filter needs to be maintained after being used for about 3 months, dust is incombustible and can be accumulated at a hole sealing part, and the common method is to adopt an inverted blowing mode, namely the flowing direction of air flow is changed to remove the dust blocked on inner wall micropores powerfully.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: the utility model aims to solve the problem that the incombustible dust aiming at the long-size honeycomb ceramic filter is difficult to completely remove and influences the service life.
The technical scheme is as follows: the utility model provides a following technical scheme:
the utility model provides a detachable honeycomb ceramic filter, includes honeycomb ceramic filter body, honeycomb ceramic filter body is divided into air inlet portion, middle part and the three part of the portion of giving vent to anger along its direction of extending, and the three part can be split each other, and air inlet portion has the terminal surface that links up with middle part and two terminal surfaces of the terminal surface of admitting air, and the portion of giving vent to anger has the terminal surface that links up with middle part and two terminal surfaces of the terminal surface of giving vent to anger, and the terminal surface of admitting air adopts the mode.
Through the design of subsection, divide into three part with honeycomb ceramic filter body for every part all has solitary function, and does not influence each other, simultaneously, in the clearance, every part can obtain better clearance effect under the prerequisite that need not to improve blowback intensity because the characteristic of its pore structure.
Further, the length of the air inlet part is larger than the depth of the hole sealing of the air inlet part.
If the length of the air inlet part is less than or equal to the depth of the hole sealing of the air inlet part, the air inlet part does not need to be subjected to back blowing, and the inner wall micropores are not positioned.
Furthermore, on the air outlet end face of the air outlet part, the through holes which are corresponding to the air inlet end face and are sealed are not sealed, and the through holes which are corresponding to the air inlet end face and are not sealed are sealed.
In another embodiment, the honeycomb ceramic filter body with another asymmetric pore structure is disclosed in the patent of this application, for example, an exhaust gas purifying device with an asymmetric pore structure, patent No. 2017210156513, both ends of which are sealed.
Further, the length of the air outlet part is larger than the depth of the hole sealing of the air outlet part.
If the length of the air outlet part is less than or equal to the depth of the hole sealing of the air outlet part, the air outlet part does not need to be subjected to back blowing, and the inner wall micropores are not positioned.
Further, the length of the middle part of the honeycomb ceramic filter body is larger than the sum of the air inlet part and the air outlet part.
The size of the honeycomb ceramic filter is limited, and for the honeycomb ceramic filter with a longer size, the effect is more remarkable by adopting the design scheme of the application.
Has the advantages that: compared with the prior art:
adopt the design scheme of the utility model, through split honeycomb ceramic filter's three, prevent that the mode through blowing upside down can't detach the dust of middle part and air inlet portion, improved the clearance effect of dust, improved the life of filter.
