Further improvement of the utility model, the filter core are made of filtrate and aluminium foil partition, and filtrate is interspersed in rugosity There are multiple aluminium foil partitions.

Further improvement of the utility model is coated with sealant between the framework and the filter layer.

Further improvement of the utility model, the sealant use polyurethane sealant.

Further improvement of the utility model, the filtrate use glass fiber filter paper material.

Further improvement of the utility model, the material of the framework are alumina material.

Further improvement of the utility model, the framework inner surface are high-temperature resistant fiber layer.

In conclusion the utility model has the following beneficial effects:

This kind of high temperature high efficiency filter, including hollow, rectangular columnar framework are equipped on the outside of the framework both ends Outer rim, the outer rim and the framework are welded, and the centre of the framework is provided through the filter layer of ventilation, the filtering The both side surface of layer is equipped with protective net, and filter core is equipped between the protective net and the filter layer, by above-mentioned design, can be with Effectively realize to for the seal protection between outer rim and framework, preventing the frame due to framework from occurring damaging and causing to filter The sealing structure of device is not tight, and structure is simple, can be further improved the intensity of framework, is hardly damaged the frame of framework, To extend the service life used.

The utility model is described in further detail with specific embodiment with reference to the accompanying drawings of the specification.

Specific embodiment

In the description of the present invention, it should be understood that term " length ", " width ", "upper", "lower", " preceding ", The orientation or positional relationship of the instructions such as " rear ", "left", "right", "vertical", "horizontal", "top", "bottom" "inner", "outside" is based on attached Orientation or positional relationship shown in figure, is merely for convenience of describing the present invention and simplifying the description, rather than indication or suggestion Signified device or element must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as to this The limitation of utility model.

Referring to Fig. 1-3, a kind of high temperature high efficiency filter disclosed by the utility model, including the columnar framework of hollow, rectangular 2, outer rim 1 is equipped on the outside of 2 both ends of the surface of framework, and positioned at the edge of frame 7, outer rim 1 and framework 2 are welded, in framework 2 Between be provided through the filter layer of ventilation, filter layer is filtration channel, and the both side surface of filter layer is equipped with protective net 4, protection Filter core is equipped between net 4 and filter layer；So as to effectively realize to for the seal protection between outer rim 1 and framework 2, prevent The sealing structure for only occurring damaging and leading to filter due to the frame 7 of framework 2 is not tight, and structure is simple, can further mention The high intensity of framework 2, wherein outer rim 1 has the function of arm supports power, when installing the product, improves installation Efficiency, so that protective action can be played and play the role of arm supports.

Filter core is made of filtrate 5 and aluminium foil partition 6, and filtrate 5 is interspersed with multiple aluminium foil partitions 6 in rugosity, and filtrate 5 is adopted With glass fiber filter paper material, after filtrate 5 is unfolded folding line at trapezoidal, certain folding away from trapezoidal folding line in be inserted with waveform aluminium foil Partition 6 increased wind contact surface, improves filter effect, reduces exhaust resistance.

Sealant is coated between framework 2 and filter layer, sealant uses polyurethane sealant, which has high drawing Intensity is stretched, there is excellent restoration, can be used for dynamic juncture, and be less prone to aging, it is adaptable.

The material of framework 2 be alumina material, aluminium oxide is also metallic aluminium, belongs to refractory material, be not easy in air by Corrosion, and high mechanical strength, hardness are big, to effectively play the role of resistant to high temperature.

Further, it is high-temperature resistant fiber layer in 2 inner surface of framework, does not soften under high temperature, remains to maintain General Mechanics The special fibre of property, also known as heat resistance fiber, fusing point and softening point are high, and fiber dimensionally stable at high temperature, macromolecular structure is not It is degradable, to effectively play the role of resistant to high temperature.

It is distributed aerial dust particle, does inertia motion or random motion, or the work by certain field force with air-flow With and move.When the particle in movement bumps against barrier, the Van der Waals between particle and blocking surfaces keeps them viscous Together.The amount of high temperature high efficiency filter traps dust is " filter efficiency " with the ratio between the Dust Capacity that do not cross in air filtering；It is fine Dimension makes bypass gas flow, generates slight resistance.The sum of the resistance of countless fibers is exactly the resistance of filter, makes the initial resistance of filter It reduces.

In embodiment, filter layer is installed in framework 2 first, between framework 2 and filter layer by filling with sealant into Row sealing is fixed, and filter core then is arranged in filter layer two sides, and filter core is between protective net 4 and filter layer, and filter core is by more A filtrate 5 and multiple aluminium foil partitions 6 composition, multiple filtrates 5 are interspersed with multiple aluminium foil partitions 6 in rugosity, and filtrate 5 and aluminium foil Partition 6 closely connects, and is fixed on 2 inside of framework, then, is provided on the surface of filter layer two sides for protecting the anti-of filter layer Protective net 4 is finally equipped with outer rim 1 on the outside of 2 both ends of framework, and positioned at the edge in 7 outside of frame, outer rim 1 and framework 2 are welded It connects, to enhance the intensity of framework 2, is hardly damaged the frame 7 of framework 2, effectively prevent the frame 7 due to framework 2 from going out It now damages and causes the sealing structure of filter not tight, cause the leakage of gas, to extend the service life used.

It deforms at high temperature under high pressure in conclusion effectively preventing this kind of high temperature high efficiency filter and leads to leakproofness It is deteriorated；So that process of the filter in filtering, gas is not easy to overflow from the installation gap of framework 2, it is ensured that filtering High efficiency and validity.

In the present invention unless specifically defined or limited otherwise, term " installation ", " connected ", " connection ", " Gu It is fixed " etc. terms shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or integral；It can be Mechanical connection, is also possible to be electrically connected；It can be directly connected, two can also be can be indirectly connected through an intermediary The interaction relationship of connection or two elements inside element.

It will be carried out in conjunction with the embodiments with technical effect of the attached drawing to the design of the utility model, specific structure and generation above It clearly and completely describes, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment It is a part of the embodiment of the utility model, rather than whole embodiments, it is based on the embodiments of the present invention, the skill of this field Art personnel other embodiments obtained without creative efforts belong to the model of the utility model protection It encloses.In addition, all connection/connection relationships being previously mentioned in text, not singly refer to that component directly connects, and referring to can be according to specific reality Situation is applied, by adding or reducing couple auxiliary, Lai Zucheng more preferably coupling structure.
