Reactor clear liquid draw-out device
Technical field
This utility model relates to a kind of chemical machinery technical field, is specifically related to a kind of reactor.
Background technology
In chemical field, when in reactor after completion of the reaction, need by reactor clear liquid extract
Out, the use for next step is prepared.Now, in most chemical plant, clear by reactor
The method that liquid extracts typically has two kinds: a kind of kettle cover being to open reactor, extracts clear liquid.So
Mode solvent can be caused to evaporate in air, cause waste.It is from still that the second takes the mode of clear liquid
Open pipe road bottom body, valve opening takes liquid.But so can make entering containing solid object of autoclave body bottom with clear liquid
Enter in reserving liquid tank, make clear liquid contain miscellaneous, meanwhile, also result in solid-liquid and do not separate.
Utility model content
The reactor clear liquid draw-out device that the purpose of this utility model is to provide, solves in above-mentioned prior art
One or multiple.
This utility model provides reactor clear liquid draw-out device, including kettle and taking out of being fixed on outside kettle
Liquid device, kettle top is provided with kettle cover, and kettle cover offers liquid taking port, and pumping device includes straight tube, side
Pipe, drawing liquid pump and reserving liquid tank.Straight tube one end seals, and is located at outside kettle, and the other end inserts through liquid taking port
In kettle under the liquid level of clear liquid, the upper end of straight tube is also associated with pneumatic means, other pipe one end and straight tube
Upper end connection, the other end connect drawing liquid pump extraction end, drawing liquid delivery side of pump connect reserving liquid tank.
The reactor clear liquid draw-out device that this utility model provides, need not open kettle cover when taking liquid, it is to avoid anti-
Answer in the solvent volatizable air in still.Straight tube, can be straight by pneumatic means regulation because being connected with pneumatic means
The height of pipe, makes straight tube be constantly in extraction process under the liquid level of clear liquid, takes liquid efficiency high, can
Extract clear liquid completely.And avoid extracting out autoclave body bottom containing solid object, it is achieved solid-liquid separation.
In some embodiments, the gap location between liquid taking port and straight tube is sealed by O.
In some embodiments, pneumatic means is cylinder, and the piston rod of cylinder is with straight tube by flange even
Connect, for controlling moving up and down of straight tube.Simple in construction, easy to operate.
Accompanying drawing explanation
The structure of the reactor clear liquid draw-out device of a kind of embodiment that Fig. 1 provides for this utility model is shown
It is intended to;
The straight tube of a kind of embodiment that Fig. 2 provides for this utility model and the structure of the connection of pneumatic means
Schematic diagram.
Detailed description of the invention
Below in conjunction with Figure of description, this utility model is described in more detail:
As shown in Figure 1, 2, the open reactor clear liquid draw-out device of this utility model, including kettle 1 with solid
Pumping device outside kettle 1, kettle 1 top is provided with kettle cover 2, kettle cover 2 offers liquid taking port
21, pumping device includes straight tube 3, other pipe 4, drawing liquid pump 5 and reserving liquid tank 6.Straight tube 3 one end seals,
Being located at outside kettle 1, the other end is inserted in kettle 1 under the liquid level of clear liquid through liquid taking port 21, takes liquid
Gap location between mouth 21 and straight tube 3 is sealed by O.Wherein, other pipe 4, drawing liquid pump 5 and storage
Liquid case 6 is respectively positioned on outside kettle 1.
The upper end of straight tube 3 is also associated with pneumatic means 7, and pneumatic means 7 also is located at outside kettle 1.Pneumatic
Device 7 is cylinder 71, and the piston rod 72 of cylinder 71 and straight tube 3, by Flange joint, are used for controlling directly
Moving up and down of pipe 3.The piston rod 72 of cylinder 71 is positioned at above straight tube 3, piston rod 72 and straight tube 3
Longitudinal center line consistent, the bottom welding of piston rod 72 has flange 1, the welded top of straight tube 3 to have
Flange 29, flange 1 and flange 29 are connected by bolt 10.By the mobile tune of piston rod 72
The height of joint straight tube 3, makes straight tube 3 be always held under clear liquid, convenient to operation.
Other pipe 4 one end connects with the upper end of straight tube 3, and the other end connects the extraction end of drawing liquid pump 5, drawing liquid
The outfan of pump 5 connects reserving liquid tank 6.
When needing drawing liquid, starting drawing liquid pump 5, clear liquid just enters reserving liquid tank 6 from other pipe 4, straight tube 3
Height is constantly reduced, it is ensured that straight tube 3 is under the liquid level of clear liquid, contains with the decline of the liquid level of clear liquid
Gu on object.Prevent from entering reserving liquid tank 6 containing solid object.So the clear liquid in kettle 1 can be taken out completely
Take clean.When clear liquid extraction is clean, close drawing liquid pump 5.
Above-described is only embodiments more of the present utility model.Ordinary skill people for this area
For Yuan, on the premise of creating design without departing from this utility model, it is also possible to make some deformation and change
Entering, these broadly fall into protection domain of the present utility model.
