Abstract
The invention discloses a high-efficiency filter which comprises a shell, a steel frame and a filter element, wherein, the top of the shell is provided with an air inlet, and a fixedly connected U-shaped space is formed between the steel frame and the outer wall of the filter element. The high-efficiency filter is characterized in that the shell is made of plastic and has a reverse U shape; and the lower end of the shell is inserted into the U-shaped space formed between the steel frame and the outer wall of the filter element. As the shell of the high-efficiency filter adopts the plastic as the raw material and can be formed by injection molding in one step, the shell has very high sealing waterproof property, anticorrosive property and antistatic performance, thus effectively solving theproblems of easy shedding of the paint or plastic coating on the surface of metal shell and air deterioration caused by dust particle generation as well as effectively reducing the cost and playing a positive role in saving energy and protecting environment.
Description
Technical field
The present invention relates to a kind of high efficiency particulate air filter, but especially relate to a kind of one-shot forming and have the high efficiency particulate air filter of water-proof function, belong to the electric mechanical product technical field.
Background technology
High efficiency particulate air filter is used for the dust particle in the filtered air, thereby improve the air quality of working environment, therefore, in fields such as semiconductor, precise electronic, medicine, medical treatment, food, army's construction machinery, metallurgy, light industry, printing and dyeing, applications, high efficiency particulate air filter is essential equipment, to create dustless, aseptic working environment.
At present, high efficiency particulate air filter generally all adopts metal shell, then the outer surface of metal shell carried out the processing of spray paint or plastics, makes high efficiency particulate air filter reach the effect of anticorrosion and antistatic.But because paint or plastics on this kind metal shell spray up, the performance of its anticorrosion and antistatic is also bad, and come off easily and oxidation, make that airborne moisture or dust particle are easy to stick on the metal shell, and cause burn into to produce oxide to housing, this makes and shortens, also can't reach the instructions for use of environment the service life of high efficiency particulate air filter that the static of its generation and oxide dust particle have had a strong impact on the environment of work, cause serious consequence; In addition, the oxide dust particle also can enter the inside of high efficiency particulate air filter simultaneously, will soon damage filter screen wherein, has further shortened the service life of high efficiency particulate air filter.
At some special career field, performance requirement to the air quality of sealing, water proofing property, anticorrosion, antistatic and the working environment of the shell of high efficiency particulate air filter is very high, and some field, its outward appearance also there is very high requirement, at present, the high efficiency particulate air filter of this shell of making of metal can not satisfy the demand in market.
Summary of the invention
In order to overcome the deficiencies in the prior art, the object of the present invention is to provide a kind of sealing, anticorrosion, antistatic performance good, but cost is low and the high efficiency particulate air filter of single injection-molded.
The present invention is achieved through the following technical solutions:
A kind of high efficiency particulate air filter, comprise shell, steel skeleton and filter core, wherein the top of shell is provided with air inlet, and steel skeleton forms a U type space of fixedlying connected with the outer wall of filter core, the material of described shell is plastics, be shaped as the ∩ type, can pass through the mould single injection-molded, the bottom of shell is inserted in the U type space of steel skeleton and the formation of filter core outer wall.
Also a FFU blower fan can be set at the air inlet place, to satisfy the specific (special) requirements of particular surroundings.
The inwall of the bottom of described shell is provided with latch, the outside wall surface of described filter core is provided with the draw-in groove that matches with described latch, perhaps the inwall of the bottom of described shell is provided with draw-in groove, and the outside wall surface of described filter core is provided with the latch that matches with described draw-in groove.
The inwall of described shell bottom is provided with reset hole and an end and is fixed on spring in the reset hole.
The internal face of kink that also can described shell is provided with the seal groove of square.
The color of described shell is any color.
The invention has the beneficial effects as follows: because the raw material that the shell of high efficiency particulate air filter of the present invention adopts are plastics, but and single injection-molded, therefore has very high water-tight, anticorrosive property and antistatic performance, the paint or the plastic coating that can effectively solve the virgin metal case surface easily come off, produce dust particle and cause the rotten problem of air, prolonged the service life of high efficiency particulate air filter, avoided serious secondary pollution, the saving of the energy and the protection of environment have been played a positive role; The present invention simultaneously also can effectively reduce original metal shell by punching press, welding, spray paint or plastics, assembling that operation spent was expensive, and install, the dismounting filter core is convenient; In addition, the present invention can change the color and the appearance and modeling of plastic casing according to different requirements, makes this kind conversion become simple.
