Further, refluxing opening is arranged on above filter layer, and water inlet is arranged at below filter layer.
This utility model has the advantages that：
Defecator for benzyl alcohol production of the present utility model makes benzyl alcohol reactant liquor bottom in and top out, fast and effeciently
Filtering reacting liquid；Dried up by compressed air in backwash process, removal filter cake, easy to clean, and improve service life, safeguard
Cycle is long.
Brief description
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or in description of the prior art the accompanying drawing of required use be briefly described it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, in the premise not paying creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
The structural representation of the defecator producing for benzyl alcohol that Fig. 1 provides for this utility model embodiment.
Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not making the premise of creative work
Lower obtained all other embodiment, broadly falls into the scope of this utility model protection.
As Fig. 1, this utility model embodiment provides a kind of defecator for benzyl alcohol production, including storage tank 1 and mistake
Filter 2, storage tank 1 lower end connects an infusion pump 3.
Filter 2 upper end connects the first air compressor 21, and filter 2 top is provided with cleaning sprayer 22, and bottom is arranged
There is sewage draining exit 23, side lower end offers water inlet 24, upper end offers refluxing opening 25, opposite side upper end offers outlet
26.It is provided with filter layer 27, filter layer 27 is constituted by being folded with filter screen in two pieces of annular clamping plate, solid by flange in filter 2
It is scheduled on filter 2 inwall.Open cleaning sprayer 22, cleaning down can be carried out to filter 2.Water inlet 24 is arranged at filter layer
Below 27, outlet 26 is arranged above filter layer 27, forms the filter type of bottom in and top out, and heavy impurity is deposited in filter
2 bottoms, light impurities hang on filter layer 27, increase the Clean after every of filter 2.
Water inlet 24 is connected with infusion pump 3 and storage tank 1 respectively by tee T, and water inlet 24 passes through feed liquor with infusion pump 3
Pipeline connects, and input duct is provided with the first visor 4.If filter 2 breaks down suddenly, reactant liquor can directly be back to storage
