Description
Technical field
This utility model relates to plastic reclaimed equipment, more specifically, it relates to a kind of waste plastics recycling device is upper
Material system and air-suction cover thereof.
Background technology
The main frame of plastic granulator is extruding machine, and it is made up of with drive system and heating, cooling system extrusion system.Suitable
For major part common technics of reclaim of plastic waste recycling, it is that waste or used plastics industrial applications again is the widest, uses the most extensive, benefit from most
The plastic reclaimed processing equipment that family is welcome.
In the waste plastics course of processing in an extruder, along with extruding, the process of thawing, in this process, will produce
Raw substantial amounts of flue gas, is doped with substantial amounts of solid particle and toxic gas, thus is using waste plastics recycling in these flue gases
The when of device, it is necessary to be equipped with the getter device being used together with extruder.
Existing getter device, the position of setting is each position, gas outlet in waste plastics recycling device, at each
Position, gas outlet arranges an air-suction cover, and air-suction cover is combined with suction system, thus is siphoned away timely by flue gas.But due to
There is substantial amounts of solid particle in flue gas, the pipeline of suction system will be blocked by after prolonged, and impact is normal
Air suction function.
For the problems referred to above, it is CN204866810U entitled " exhaust apparatus of a kind of plastic reclaimed equipment " at notification number
Chinese patent in disclose a kind of structure, its general scheme arranges filter assemblies exactly between range hood to discharge duct,
Such that it is able to just can adsorb in filter assemblies before the solid particle in flue gas is entered into discharge duct, and then protect
Discharge duct, but set-up mode here, filter assemblies is directly to be embedded in range hood, for non-dismountable setting, makes
After a period of time, filter assemblies is also easy to lose efficacy, and is blocked by solid particle, thus loses the use function of range hood.
Utility model content
According to above-mentioned shortcoming and defect, the first purpose of the present utility model is to provide a kind of being capable of in flue gas
Solid particle carries out the air-suction cover filtered and filter assemblies can conveniently be dismantled with air-suction cover.
Above-mentioned technical purpose one of the present utility model has the technical scheme that a kind of air-suction cover, bag
Including the housing of air-suction cover, described housing includes coniform first cover body arranged continuously from top to bottom, is arranged under the first cover body
Cylindrical the second cover body in portion, it is arranged on the 3rd cover body that the second cover body bottom is horn-like expansion, on described second cover body
Being removably connected with filter assemblies, described filter assemblies includes the retainer of a Ring-cylindrical, is provided with filter opening big in retainer
Little the first screen plate, the second screen plate and the 3rd screen plate being sequentially reduced.
By such scheme, flue gas from passing sequentially through the 3rd cover body, the second cover body and the first cover body, and will be arranged on
Filter assemblies in two cover bodies will can fall the most solid particulate filters in flue gas, and the first screen plate, the second mistake
The filter opening of filter plate and the 3rd screen plate is gradually reduced so that the solid particle in flue gas can be stopped step by step, and in air-breathing
Time, flue gas is by the air-suction cover that is inhaled in upward status, and keeps off the solid between the first screen plate and the second screen plate
Grain, gear solid particle between the second screen plate and the 3rd screen plate will lump during gradually accumulation, thus stop
Only will be clipped between each screen plate when of air-breathing, and filter assemblies and the mode that removably connects of the second cover body, it is possible to real
Existing filter assemblies, by splitting out easily from the second cover body after the 3rd cover body of horn-like expansion, is carried out or more
Change, it is ensured that the normal suction of air-suction cover and filter effect.
It is optimized for further: be threaded connection between described retainer and the second cover body.
By such scheme, covered by the threaded filter assemblies and second that realizes between retainer and the second cover body
Removably between body.
It is optimized for further: connected by latch between described retainer and the second cover body.
By such scheme, directly can be inserted through the second housing and retainer by latch, silly line filter assemblies and second
Removably between cover body.
It is optimized for further: be provided with the recessed groove along generatrix direction on the inner ring surface of described retainer, at recessed groove
Middle part, it is provided with the draw-in groove along retainer inner ring surface circumference depression near the position at retainer two ends, and described draw-in groove and recessed
The groove width falling into groove is identical, is provided with and draw-in groove phase at the outline of the first screen plate, the second screen plate and the 3rd screen plate
The fixture block coordinated.
By such scheme, installing the first screen plate when so that the fixture block on the first screen plate faces toward retainer
Recessed groove input, the when of then arrive corresponding draw-in groove, rotate the first screen plate so that in fixture block screw-in draw-in groove, the most just can
Realize the installation of the first screen plate, same steps can also be used to pacify the second screen plate and three screen plates are installed when
Dress, thus realize conveniently removably connecting between the first screen plate, the second screen plate and the 3rd screen plate and retainer, clearly
The when of washing filter assemblies, convenient.
It is optimized for further: described retainer is additionally provided with striker plate relative to the side of the 3rd cover body, the foreign steamer of striker plate
Between exterior feature and the 3rd cover body, there is gap, be connected by connecting rod between described striker plate and retainer.
By such scheme, air-breathing when, flue gas can be entered by the gap between striker plate and the 3rd cover body
Second cover body then passes to the first cover body, thus the setting of striker plate can't affect the air-suction cover absorption to flue gas, and due to
The setting of striker plate, when the solid particle being accumulated in filter assemblies being dropped due to vibrations or other unstable factors, meeting
Caught by striker plate, without directly dropping to the position, gas outlet of extruder, thus improve extruder work quality and
The stability of extruded material.
It is optimized for further: the outline of described striker plate is coning and tip is towards the opening of the 3rd cover body, backgauge
Plate is set to the concave face of cone relative to the one side of retainer.
By such scheme, the outline of striker plate arranging the cone down in tip, flue gas is entering the 3rd cover
The when of body, it is possible to preferably be directed into flowing to the gap between striker plate and the 3rd cover body by striker plate outline
Position；And striker plate is arranged to the concave face of cone, then relative to the one side of retainer, it is possible to catch and deposit more from
The solid particle dropped in filter assemblies, improves practical function.
Second purpose of the present utility model is to provide a kind of waste plastics recycling that at least can solve the problem that above-mentioned technical problem
The feeding system of device.
Above-mentioned technical purpose two of the present utility model has the technical scheme that a kind of waste plastics returns again
The feeding system of receiving apparatus, includes the air-suction cover in technique scheme.
In sum, air-suction cover is shaped to cone shape first cover body, columned second cover body and loudspeaker
3rd cover body of shape so that the second cover body can removably connect and arrange filter assemblies, it is possible to realize filter assemblies the most clear
Washing and change function, the function that can meet air-breathing filtration for air-suction cover for a long time is guaranteed.
