Background technology
Contain certain moisture in liquid crystal polymer after production, it is therefore desirable to it is dried processing.It is existing dry
Dry equipment, is carried out, often rotating speed is higher for this mode, and liquid crystal polymer is caused brokenly using rotating centrifugal drying mode mostly
It is bad, or because rotating speed is low and caused by dry it is insufficient, be not thorough, efficiency is low.
Utility model content
For above-mentioned deficiency, done the purpose of this utility model is to provide a kind of production of liquid crystal polymer with circulating hot nitrogen
Dry device, reasonable in design, dry quick, drying effect is good, dry thorough, to liquid crystal polymer without damage.
The utility model is that technical solution is used by reaching above-mentioned purpose：
A kind of circulating hot nitrogen drying device of liquid crystal polymer production, including a drying cavity, on the drying cavity
End has a feed inlet and a gas outlet, it is characterised in that inner wall projection laterally forms an annular in the middle part of the dry cavity
Nitrogen enters passage, enters in the annular nitrogen in passage and is equipped with an infrared heating tube, and enters in the annular nitrogen and lead to
Some nitrogen inlets are uniformly provided with road side；Upper lateral is equipped with a hollow clapboard in the drying chamber body, hollow at this
Molecular sieve is filled with partition plate, and some material paths are uniformly provided with the hollow clapboard.
As further improvement of the utility model, enter in the drying chamber body and positioned at annular nitrogen above passage
It is horizontal to have a gas distribution grid, some through holes are uniformly provided with the gas distribution grid.
As further improvement of the utility model, a rotation is provided with the gas outlet lower end and in drying chamber body
Wind separator.
As further improvement of the utility model, bottom offers a discharge port in the drying chamber body, and at this
Discharge outlet is provided with a detachable bottom cover.
The beneficial effects of the utility model are：By setting annular nitrogen to enter passage, using same in dry cavity surrounding
The mode of Shi Jinqi, improves nitrogen distribution consistency degree in drying chamber body, beneficial to raising drying effect；Using point in hollow clapboard
Son sieve carries out preliminarily dried to liquid crystal polymer, then use high temperature hot nitrogen with need dry liquid crystal polymer carry out heat exchange with
By the moisture vaporization in liquid crystal polymer, it can be achieved that carrying out circulating continual drying process, structure design to liquid crystal polymer
Rationally, rate of drying faster, and drying it is more thorough, so that drying efficiency is improved, to liquid crystal polymer without damage.
Above-mentioned is the general introduction of utility model technical solution, below in conjunction with attached drawing and embodiment, to the utility model
It is described further.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Embodiment
Further to illustrate that the utility model is to reach the technological means and effect that predetermined purpose taken, below in conjunction with
Attached drawing and preferred embodiment, describe specific embodiment of the present utility model in detail.
Fig. 1 is refer to, the utility model embodiment provides a kind of liquid crystal polymer production circulating hot nitrogen drying device,
Including a drying cavity 1, there is a feed inlet 11 and a gas outlet 12, the dry middle part of cavity 1 in 1 upper end of drying cavity
Inner wall projection laterally forms an annular nitrogen and enters passage 13, enters in the annular nitrogen in passage 13 and is equipped with an infrared ray
Heat-generating pipe 14, and enter in the annular nitrogen on 13 side of passage and be uniformly provided with some nitrogen inlets 131；In the drying chamber
1 internal upper part of body is horizontal a hollow clapboard 15, and molecular sieve is filled with the hollow clapboard 15, and on the hollow clapboard 15
It is even to offer some material paths 151.
In the present embodiment, enter in the dry cavity 1 and positioned at annular nitrogen and horizontal above passage 13 have a gas
Body distribution grid 16, some through holes are uniformly provided with the gas distribution grid 16.
Meanwhile it is provided with a cyclone separator 17 in 12 lower end of gas outlet and in dry cavity 1.
In the present embodiment, bottom offers a discharge port 18 in the dry cavity 1, and is set at the discharge port 18
It is equipped with a detachable bottom cover 19.
During work, nitrogen enters annular nitrogen from nitrogen inlet 131 and enters in passage 13, enters passage into annular nitrogen
When nitrogen in 13 passes through infrared heating tube 14, hot nitrogen is heated to form, hot nitrogen passes sequentially through gas distribution grid 16 upwards
With hollow clapboard 15；Simultaneously, liquid crystal polymer material is added from feed inlet 11, liquid crystal polymer material falls on hollow clapboard
On 15, by the moisture in the molecular sieve initial absorption liquid crystal polymer in hollow clapboard 15；Then, liquid crystal polymer material passes through
Gas distribution grid 16, in the process, liquid crystal polymer material are further dried by hot nitrogen, and last liquid crystal polymer material falls
To at discharge port 18, and it can be moved out by detachable bottom cover 19, exhaust gas is discharged from gas outlet 12.
The emphasis of the utility model essentially consists in, by setting annular nitrogen to enter passage, using in dry cavity surrounding
The mode of air inlet at the same time, improves nitrogen distribution consistency degree in drying chamber body, beneficial to raising drying effect；Using in hollow clapboard
Molecular sieve carries out liquid crystal polymer preliminarily dried, then using high temperature hot nitrogen with needing dry liquid crystal polymer to carry out heat exchange
With by the moisture vaporization in liquid crystal polymer, it can be achieved that carrying out circulating continual drying process to liquid crystal polymer, structure is set
Meter is reasonable, and faster, and drying is more thorough for rate of drying, so that drying efficiency is improved, to liquid crystal polymer without damage.
The above descriptions are merely preferred embodiments of the present invention, and not the technical scope of the utility model is made
Any restrictions, therefore identical with the utility model above-described embodiment or approximate technical characteristic is used, and obtained other structures,
Within the scope of protection of the utility model.
