Description
Technical field
The utility model is related to EPP particle density technical field of measurement and test, specifically, is a kind of EPP particles delivery pipe
Road takes density devices.
Background technology
In the production that expanded polypropylene is EPP, when EPP particulates are sent out from reactor, it is necessary to grasp EPP particles in time
Density, it is ensured that the density of EPP particles is in control range.
But, because the internal pipe pressure for conveying EPP particles is larger, it is very inconvenient to sample, if taken in pipe end
Sample, the density measured can not adjust the density that EPP is sent out out of kettle in time, cause product final densities to deviate with target density
It is larger, influence the quality of final products.
The content of the invention
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of EPP particles conveyance conduit and takes density to fill
Put, be sampled in the middle part of the device and conveyance conduit, it can be ensured that product density is accurate, it is ensured that product quality.
To reach above-mentioned purpose, the technical solution adopted in the utility model is as follows：
A kind of EPP particles conveyance conduit takes density devices, including particle conveying pipeline, and its key is：It is defeated in the particle
Sampling pipe is connected with expects pipe, sampling actuating unit is provided with the sampling pipe, the sampling actuating unit is used for will
EPP particles send into particle density test device by sampling pipe.
Further, triple valve is additionally provided with the sampling pipe, and the triple valve is located at the sampling engine
Between structure and particle density test device, the first outlet of the triple valve exports particle to particle density test device, described
The second outlet of triple valve is connected by feed back pipeline with the particle conveying pipeline.
Further, the triple valve is Electrocontrolled tee valve.
Further, the sampling actuating unit is blower fan.
Remarkable result of the present utility model is：It is simple in construction, it is easy to control, outside particle conveying pipeline connect sampling pipe with
Feed back pipeline and form a loop, fan outlet install a triple valve, EPP particles are conveyed when the triple valve is normally closed
To sample tap, ion concentration test is carried out to send into particle density test device, it is defeated that EPP particles are transported into particle when normally opened
In expects pipe, once needing sampling, open normally closed and closing is normally opened, once sampling completes to close normally closed and opens normally opened, and pass through
Blower fan sends the particle in loop in particle conveying pipeline back to, ensures that product density is accurate, it is ensured that product quality.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment of the present utility model and operation principle are described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of EPP particles conveyance conduit takes density devices, including particle conveying pipeline 1, it is defeated in the particle
Sampling pipe 2 is connected with expects pipe 1, sampling actuating unit 3 is provided with the sampling pipe 2, the sampling actuating unit 3 is used
In EPP particles are sent into particle density test device by sampling pipe 2.
It can further be seen from figure 1 that triple valve 4 is additionally provided with the sampling pipe 2, and the triple valve 4 is located at institute
State between sampling actuating unit 3 and particle density test device, the first outlet of the triple valve 4 exports particle to particle density
Test device, the second outlet of the triple valve 4 is connected by feed back pipeline 5 with the particle conveying pipeline 1.
By above-mentioned triple valve 4, gating can be realized between sampling pipe 2 and feed back pipeline 5, when need carry out particle
Sampling pipe 2 and particle density test device are gated during density measurement；Backgating sampling pipe 2 and feed back are completed in particle test
Pipeline 5, and the particle in pipeline is blown into particle conveying pipeline 1 by sampling actuating unit 3, so as to avoid EPP Particles Blockings
Sampling pipe 2, is easy to the progress of next particle density test.
In the present embodiment, the triple valve 4 is Electrocontrolled tee valve, and Automated condtrol is easy to implement by Electrocontrolled tee valve,
So as to reduce labor intensity, human input is reduced, production cost is saved, production efficiency is improved.
In the present embodiment, difficulty is realized in order to reduce, cost of implementation is reduced, the sampling actuating unit 3 is blower fan.
The present apparatus forms a loop by the connection sampling pipe 2 outside particle conveying pipeline 1 and feed back pipeline 5,
A triple valve 4 is installed in the outlet of blower fan 3, and EPP particles are transported to sample tap by the triple valve 4 when normally closed, close to send into particle
Spend test device and carry out ion concentration test, EPP particles are transported in particle conveying pipeline 1 when normally opened, once needing sampling, beat
Open normally closed and closing is normally opened, once sampling completes to close normally closed and opens normally opened, and the particle in loop is sent back to by blower fan 3
In particle conveying pipeline 1, ensure that product density is accurate, it is ensured that product quality.
