Description
Technical field
This utility model relates to chemical machinery field, especially relates to a kind of chemical industry decanter type backwash filter.
Background technology
It is frequently necessary to be filtered in chemical process carries out, filter typically to the impurity removed in raw material or product, solid-liquid separation etc., so that it is guaranteed that the quality of finished product, equipment run interference-free, technological process can be smoothed out. But most Chemical Manufacture or experimental occasions are also at the filter using common form at present; although this filter is relatively simple for structure; less costly; but in use in filter due to liquid flowing compared with slow, impulsive force is little; solids is easily at filter screen place adventitious deposit; filter screen is frequently occluded; thus limiting effective use of filter; easily impact to technical process; owing to plain filter can not reverse flushing filter screen; change once blocking is accomplished by shutting down or cleans filter screen, having a strong impact on production efficiency.
Summary of the invention
The technical problems to be solved in the utility model is: in order to overcome above-mentioned middle Problems existing, provide a kind of chemical industry decanter type backwash filter, it is rational in infrastructure, there is the advantages such as simple in construction, easy to use, energy back flush filter screen, filter screen are not easily blocked, the problem effectively solving chemical filter filter net jam.
This utility model solves its technical problem and be the technical scheme is that a kind of chemical industry decanter type backwash filter, including expansion chamber and the inlet of expansion chamber cross connection respectively, liquid outlet and the sewage draining exit that vertically connects with expansion chamber, described liquid outlet and expansion chamber, by mutually threadeding with externally threaded ring-type filter screen set, oblique in ring-type filter screen set are fixedly installed filter screen;
Being interconnected by recoil tube between described inlet and liquid outlet, and be provided with the valve for controlling recoil tube opening and closing on recoil tube, described recoil tube one end and inlet are welded to each other, and the other end of recoil tube is threadeded mutually with liquid outlet.
As preferred scheme, described expansion chamber, inlet and sewage draining exit are integral structures.
As preferred scheme, described valve is electromagnetic valve.
As preferred scheme, the end of described inlet, liquid outlet and sewage draining exit is respectively arranged with the adpting flange of integral structure.
As preferred scheme, described filter screen and horizontal plane angulation are 30��80 ��.
The beneficial effects of the utility model are: a kind of chemical industry decanter type backwash filter, including expansion chamber and the inlet of expansion chamber cross connection respectively, liquid outlet and the sewage draining exit that vertically connects with expansion chamber, angularly disposed filter screen is had between expansion chamber and liquid outlet, solid on filter screen easy natural subsidence under gravity is in expansion chamber, inlet connects with recoil tube with liquid outlet, open recoil tube, sewage draining exit and inlet and close liquid outlet and get final product reverse flushing filter screen, operation need not be shut down, improve production efficiency; It is rational in infrastructure, has the advantages such as simple in construction, easy to use, energy back flush filter screen, filter screen are not easily blocked, the problem effectively solving chemical filter filter net jam.
Accompanying drawing explanation
