2, detachable filter screen is set to one layer of filtering more than electrolyte, realizes secondary filter, fills electrolyte filtering more Point；Holding rod in the middle part of filter screen facilitates and filter screen is packed into and is taken out, while holding rod top is contacted with bung, can be to filtering Upward activity is limited when net cover is in filter vat.

3, filter vat upper cylinder, the integrated container design of lower part inverted ladder-shaped body, can be to being slidably mounted on filter vat Interior filter screen, which moves downward, to be limited.

4, filter screen includes contaminant filter layer and moisture filter layer, can filter impurity and water in electrolyte well Point, and contaminant filter layer and the splicing installation of moisture filter layer installation and are dismantled after to be respectively washed and more before convenient to use It changes.

5, the part that discharge nozzle stretches out outside staving is equipped with pump, can both extract the filtered electrolyte of completion, can also be with The sewage after bucket inner wall has been cleaned in extraction, facilitates the cleaning of staving.

Detailed description of the invention

Fig. 1 is the utility model section structural schematic diagram.

In figure: filter vat 1, bung 2, feeding pipe 4, discharge nozzle 5, filter screen 6, pump 7 filter net cage 8, connecting cylinder 9, holding rod 61, contaminant filter layer 62, moisture filter layer 63.

Specific embodiment

The utility model is described in further detail below in conjunction with attached drawing, specific embodiment and specific embodiment:

It is upper on the filter vat 1 to be furnished with bung 2 as shown in Figure 1, a kind of filter device of electrolyte, including filter vat 1, Feeding pipe 4 is provided on the bung 2,1 lower sides of filter vat are equipped with discharge nozzle 5, the bung 2 and the filtering Bucket 1 is tightly connected, and the circle that the bung 2 is contacted with 1 oral area of staving is equipped with sealing ring, guarantees filter vat 1 when in use Inner seal ring border is easy to open bung 2 to cleaning inside filter vat 1 after being finished, aspect is packed into and takes out in filter vat 1 Component.

The feeding pipe 4 protrudes into filter vat 1 and is connected with filtering net cage 8, the filtering net cage 8 and the feeding pipe 4 It is detachably connected；Filter screen 6 is also slidably fitted in the filter vat 1,6 diameter of filter screen is consistent with bung hole internal diameter.

In the application, the filtering net cage 8 is equipped with connecting cylinder 9, enters described in the helicitic texture cooperation of 9 outer wall of connecting cylinder The helicitic texture of 4 inner wall of expects pipe is threadedly coupled.

Filtering net cage 8 and filter screen 6 facilitate installing and dismounting to be replaced and cleaned.

In the application, the filter vat 1 is upper cylinder, the integrated container of lower part inverted ladder-shaped body.

In the application, be equipped with the holding rod 61 that stretches out to 2 direction of bung in the middle part of the filter screen 6,61 top of holding rod and Bung 2 contacts.Increase a filter screen 6 detachably installed and multistage filtering is carried out to electrolyte, keeps filtering more abundant, filtering Net 6 is sleeved in filter vat 1, and filter screen 6 is equipped with holding rod 61, convenient to use to disassemble cleaning or replacement later.
