Description
Technical field
When the technical problems to be solved in the utility model is plastic master batch production, the problem of the filtering of melt, specifically relate to
And a kind of plastic master batch production filter device, the utility model belong to plastic master batch production field.
Background technology
Currently, plastic master batch prepares the production technology generally by double-screw extruding pelletizing, in the process, various originals
Expect that the heating extrusion through twin-screw becomes melt, melt inlet port after a simple filter device again after mixing
Mould becomes slice extrusion, plastic master batch then is made through cooling and pelletizing.Wherein its filter device is usually used single more
Layer filter screen structure, and by the disengaging of pneumatic device control strainer.Strainer in use for some time, will be timed replacement,
To ensure quality and filtration pressure difference into the material of die head.
The disadvantage is that：
Existing filter device is although relatively simple, but since it is single filter chamber, so needing to interrupt when replacing
Production, influences production efficiency.
Lead to reason：
This is that existing twin-screw filter device is when needing replacing strainer, to need to use people using the structure of single filter chamber
Work or pneumatic device extract strainer, can at this time cause melt pressure fluctuation to influence the matter of the stability and product of production
Amount, or even need to interrupt production, to influence production efficiency.
Utility model content
The influence caused by production, provides a kind of plastic master batch when the utility model replaces strainer for existing filter device
Production filter device, production process, which may be implemented, without strainer, strainer is needed to change to ensure the stabilization of production with automated cleaning
Property, improve production efficiency.
In order to solve the above-mentioned technical problem, the utility model is achieved through the following technical solutions：
A kind of plastic master batch production filter device, including melt inlet channel, the melt inlet channel connect front left
Channel and front right channel, the front left channel and front right channel are respectively communicated with left filter chamber and right filter chamber, the left filter chamber and right filter
Room is equipped with strainer, and the left filter chamber and right filter chamber are equipped with discharging channel, and the discharging channel is equipped with blow-off valve, the left filter
The other end of room and right filter chamber is separately connected rear left channel and rear right channel, and the other end in the rear left channel and rear right channel is equal
Melt outlet channel is connected, the front left channel and front right channel are equipped with preceding triple valve, the rear left channel and rear right channel
Be equipped with rear triple valve, before the preceding triple valve with pressure sensor is respectively set after rear triple valve.
Further, the preceding triple valve and rear triple valve are controlled by handwheel.
Further, the spool of the preceding triple valve and rear triple valve is the thick intermediate thin dumbbell shape in both ends.
Compared with prior art, the utility model has the beneficial effects that：
Strainer automatically cleaning may be implemented in the utility model, and production process replaces strainer without shutting down, and carries out filter chamber switching
When, melt flow fluctuation is small in production process, is effectively improved production efficiency without influence to production stability substantially
And product quality.
This is because the present apparatus uses double filter chambers and double triple valves, by the switching of front and back triple valve, melt is from one
During filter chamber is turned over to another filter chamber, the flowing of melt only distributes the flow in two filter chambers there is no interrupting
Ratio is different, therefore its flow not will produce significant change substantially, stablizes to be effectively improved production when draping
Property.
It is distributed simultaneously by the melt of triple valve, realizes the adverse current of melt, add the setting of drain valve, it is effectively real
The automatically cleaning of strainer is showed.Therefore ensure that the continuity of production carries out, reduce waste.
Description of the drawings
Attached drawing is used to provide a further understanding of the present invention, for explaining together with the embodiments of the present invention
The utility model does not constitute limitations of the present invention, in the accompanying drawings：

Specific implementation mode
The preferred embodiment of the utility model is illustrated below in conjunction with attached drawing, it should be understood that described herein excellent
It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.
A kind of plastic master batch production described in the utility model is with filter device mainly by preceding triple valve 1 and rear triple valve 2, a left side
The compositions such as filter chamber 3 and right filter chamber 4, drain valve 5.The plastic melt squeezed out by double spiral shells is led to by melt inlet channel 6 into front left
Road 7 and front right channel 8 make melt enter as needed by the control of the preceding triple valve 1 on front left channel 7 and front right channel 8
Left filter chamber 3 or right filter chamber 4 go out then by the control of the rear triple valve 2 on rear left channel 9 and rear right channel 10 into molten mouth
Mouth channel 11, subsequently into extruding dies.Triple valve is controlled the movement of its spool by the rotation of handwheel 12, to realize flowing
The transformation in direction.Pressure sensor is respectively set with after rear triple valve 2 before preceding triple valve 1, for monitoring melt pressure
Variation.
With the progress of production, the impurity on strainer in filter chamber is more and more, after the pressure difference of strainer reaches a certain level,
Front and back handwheel 12 is rotated simultaneously, and melt is assigned to by another filter chamber by the effect of preceding triple valve 1 and rear triple valve 2,
In preceding triple valve 1 mobile degree it is larger, melt fully enters another filter chamber, but to move degree smaller for rear triple valve 2,
Most of melt enters melt outlet channel, and small part melt opens the row of former filter chamber by 2 adverse current of rear triple valve to former filter chamber
Valve 5 is put, melt is countercurrently discharged, and during melt adverse current is discharged, the impurity on strainer is also discharged with melt, and strainer is realized certainly
Cleaning.Rear triple valve 2 is at this time continued to move to, allows whole melts to carry out melt outlet, is normally produced.Thus and thus when new
When the filtration pressure difference of filter chamber is larger, aforesaid operations are executed again, until next cycle.
The utility model is by being provided with double filter chambers, and by preceding triple valve 1 and rear triple valve 2, two triple valves
Switching acts on, and melt can be directed respectively into two filter chambers in left and right, realize that the automatically cleaning of strainer, production process need not replace filter
Net.
Finally it should be noted that：The preferred embodiment that these are only the utility model, is not limited to this practicality
It is novel, although the utility model is described in detail with reference to embodiment, for those skilled in the art, according to
So can be with technical scheme described in the above embodiments is modified, or which part technical characteristic is equally replaced
It changes, but within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should all include
It is within the protection scope of the utility model.
