In order to remove the particulates emission impurity in the smectic liquid crystal, need to filter smectic liquid crystal.But, be not specifically designed at present the filter of smectic liquid crystal, filter that nematic liquid crystal is filtered has only appearred, these devices are: a kind of liquid-crystal positive-pressure filter unit that the patent No. provides for the Chinese utility model patent of ZL201120073200.1, and this filter is the device that nitrogen adds positive press filtration under a kind of normal temperature; A kind of suction filtration device for liquid crystal filtering that the patent No. provides for the Chinese utility model patent of ZL200920059373.0, this suction filtration device is a kind of absorbing devices of normal temperature negative pressure; A kind of crystal filling device that the patent No. provides for the Chinese utility model patent of ZL200920110587.6, this crystal filling device are a kind of crystal filling devices by negative and positive the two poles of the earth adion.Above-mentioned these devices can both reach good filter effect when nematic liquid crystal is filtered.
But, if the above-mentioned filter that nematic liquid crystal is filtered is used for smectic liquid crystal is filtered, just can there be following defective:
The first, nematic liquid crystal at normal temperatures viscosity is very little, and smectic liquid crystal viscosity is very large at normal temperatures, therefore, above-mentioned liquid-crystal positive-pressure filter unit, suction filtration device can can't be implemented because smectic liquid crystal viscosity is excessive at normal temperatures;
The second, the purpose of above-mentioned crystal filling device is to remove ion, but the object that smectic liquid crystal will be removed is different from nematic liquid crystal, and therefore, this crystal filling device is applied to smectic liquid crystal without practical value.
This shows, the filter that is applicable to nematic liquid crystal can't be applied to smectic liquid crystal, and urgent problem provides a kind of device that can filter at normal temperatures the high viscosity smectic liquid crystal at present.
The utility model content
The purpose of this utility model is to provide a kind of smectic liquid crystal filter, and this filter can filter the high viscosity smectic liquid crystal at normal temperatures, and filter effect is good.
To achieve these goals, the utility model has adopted following technical scheme:
A kind of smectic liquid crystal filter, it is characterized in that: it comprises the tank body of lower open mouth, upper shed on this tank body top is provided with seal cover, sealing covers to be provided with in this tank body and passes into the guide pipeline that filters with gas, under shed on this tank body bottom is connected with the upper port of funnel, be provided with filter paper between the under shed of this tank body and the upper port of this funnel, it is the heated for controlling temperature layer that the smectic liquid crystal heating-up temperature is regulated in the tank body that the outer wall of this tank body is provided with pre-, and the control end of this heated for controlling temperature layer is connected with attemperating unit.
Described tank body is the stainless steel cylinder of steel.
Described tank body be shaped as funnel-form.
On the under shed of described tank body, the upper port of described funnel flange is housed all, achieves a fixed connection via this flange of clip clamping between the under shed of described tank body, the upper port of described funnel.
Described funnel below is placed with and connects the liquid bottle.
The utility model has the advantages that:
The utility model is simple and practical, can come full-bodied smectic liquid crystal is filtered by heating malleation mode at normal temperatures, and filter effect is good, can with the particulates emission impurity filtering in the smectic liquid crystal, greatly improve the quality of smectic liquid crystal.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model smectic liquid crystal filter comprises the tank body 10 of lower open mouth, upper shed on these tank body 10 tops is provided with seal cover 11, sealing lid 11 is provided with in this tank body 10 and passes into the guide pipeline 12 that filters with gas, under shed on these tank body 10 bottoms is connected with the upper port of funnel 20, be provided with filter paper 30 between the upper port of the under shed of this tank body 10 and this funnel 20, the outer wall of this tank body 10 is provided with the heated for controlling temperature layer 13 of regulating for tank body 10 interior smectic liquid crystal heating-up temperatures in advance, and the control end of this heated for controlling temperature layer 13 is connected with the control end of attemperating unit (not shown).
Such as Fig. 1, one port of this guide pipeline 12 is connected with the opening (not shown) that sealing is covered on 11, the another port of this guide pipeline 12 links to each other with the delivery outlet of reserve of gas tank (not shown), the inner chamber of this guide pipeline 12 communicates with the inner chamber of this tank body 10, sends in the tank body 10 via guide pipeline 12 to be used for will filtering with gas.
In actual design, tank body 10 can be the stainless steel cylinder of steel.Such as Fig. 1, the shape of tank body 10 can be funnel-form, and under shed is less than upper shed, and tank body 10 bottoms are skewed, so that liquid crystal moves downward.
