Electric energy comes from the lead-acid battery in installed therein.
Lead-acid battery is a kind of accumulator of traditional sustainable use, as scientific and technological is constantly progressive, lead-acid battery
Capacity is stepping up, but thing has pros and cons, in the prior art, is carried out often through lead plaster is smeared on electrode plate chemical anti-
It answers, generates electric current, but lead plaster belongs to the colloid of wet shape, is exposed to for a long time in electrolyte (concentrated sulfuric acid), it can pushing away with the time
Falling off slowly is moved, to reduce the service life of battery, and improves the danger during battery use.Battery also can be with
Use, electrolyte stratification occurs, further reduces the service life of battery.
Chinese patent CN103534864B disclosed a kind of lead-acid battery, main contents one on November 23rd, 2016
Kind lead accumulator, has electrode assembly and electrolyte being accommodated in the structure in battery case simultaneously, be right under the charged state of part
The flooded lead-acid battery that load discharges, the electrode assembly are will to be filled in negative electrode collector by negative electrode active material to be formed
Negative plate is filled in what the positive plate that positive electrode collector is formed was formed across diaphragm stacking with by positive active material, described
On negative plate, non-woven fabrics is connected to pad-face entirety with pole plate non-integral, and the non-woven fabrics is by being selected from glass, paper pulp and gathering
The fiber of at least one of the material group that alkene is constituted material is constituted, and the negative plate abutted with the non-woven fabrics is accommodated in
In the bag-shaped diaphragm be made of micro- porous synthetic resin board.
Although solving the problems, such as that will appear electrolyte using lead-acid battery for a long time detaches using the above scheme, it is simultaneously
The problem of unresolved lead plaster being attached on electrode plate falls off.
Utility model content
The utility model aim is to provide a kind of pocket type diaphragm, meet in cell fabrication processes, in the week of electrode plate
It encloses and superscribes layer of glass film, reduce the problem of lead plaster falls off with electrolyte contacts for a long time, extend making for lead-acid battery
Use the service life.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is as follows：
Pocket type diaphragm, including bag body, bag body include more than two diaphragm cells being fixedly connected, and the inner wall of diaphragm cell is solid
Surely be equipped with barrier piece, barrier piece is arranged in pairs, and barrier piece is obliquely installed, and the bottom of diaphragm cell is equipped with slot, slot through
Entire bag body, the slot is interior to be equipped with grid.
The technical principle of the technical program is：Bag body includes several diaphragm cells, wherein each diaphragm cell connects each other,
By the way that the slot connection in diaphragm cell bottom is arranged；Before pack, the lotion bottom that each cutting is completed is provided with circular hole,
Circular hole herein and the slot of diaphragm cell bottom cooperate, and grid is installed in slot, by circular hole by each independent plate
Grid structure connects.The barrier piece tilted down is provided on diaphragm inner wall, barrier piece is set up in pairs, and installation is complete by grid
Afterwards, grid is fixed in barrier piece expenditure part, the lotion on grid is locked in certain spatial dimension, even if lead plaster is de-
Prodigious harm will not be caused by falling.Over time, part lead plaster drops to diaphragm cell bottom, can pass through setting
Grid in diaphragm cell bottom continues to react with electrolyte.
Using the technical program：The barrier piece being arranged on diaphragm cell inner wall, the lead plaster that will fall off are locked in certain
It in spatial dimension, prevents lead plaster from continuing to fall off, extends the service life of lead-acid battery.By being arranged in diaphragm cell bottom
Slot links together all grids, and the lead plaster to fall off is touched on the grid of slot, can continue and be electrolysed
Qualitative response solves the problems, such as the shortening of battery service life, improves the safety that battery uses.
Further, be connected together grooved hole cap at the port of the slot.
Using the technical program：Electrolyte and lead plaster can be isolated by the slot cap being arranged at slot port, is kept away
Exempting from lead plaster can fall in electrolyte for a long time.
Further, bag body includes fibrous material, and the fibrous material is one in the material group of glass, paper pulp and polyolefin
Kind is a variety of.
Using the technical program：Using bag body made of glass, paper pulp and polyolefin one of which or different materials,
Many intensive apertures are had on bag body, electrolyte is facilitated to pass in and out, and the outer wall made of the above material has absorption electrolyte
Function can increase contact of the lead plaster with electrolyte, so as to stable power-supplying.
Further, barrier piece is non-woven fabrics, and non-woven fabrics is fixedly connected on the diaphragm cell by the way of sewing machine sewing
Inner wall on.
Using the technical program：Barrier piece is made of non-woven fabrics, can adsorb electrolyte, to enhance electrolyte and lead
The reaction of cream by way of sewing machine sewing on the outer wall by the sewing of barrier piece enhances the connection of barrier piece and outer wall.For lead
The fixation of cream provides guarantee.
