Abstract

The utility model relates to the improvement of an external electrolyte circulation connector used for the formation of a lead acid storage battery. The connector is characterized in that the connector comprises a sealing cover and a plastic integrated body comprising a liquid inlet tube and a liquid outlet tube which are parallel and penetrate the sealing cover; a ring groove used for placing the sealing ring is formed on the radial peripheral surface of the sealing cover; liquid inlet tube orifices inside and outside the battery are higher than liquid outlet tube orifices inside and outside the battery; and filtering units are arranged on inlet and outlet liquid orifices. The utility model has the advantages that the shortcomings of the prior art are overcome, the consistency of the liquid level of each battery is good, the connector can be repeatedly used, the damage to the battery is slight, and the blockage in the pipeline can be avoided.

Description

Storage battery changes into electrolyte outer circulation connector

Technical field

Utility model is that lead acid accumulator is changed into the improvement of using electrolyte outer circulation connector.

Background technology

Chinese patent CN201069798 discloses a kind of external sour cycle battery connector, and by seal cover with insert the acid inlet tube of seal cover and go out acid tube and forms, and the acid inlet tube mouth all is lower than the acid tube mouth inside and outside the battery.Yet still there is some deficiency in this connector, and for example the acid inlet tube mouth is low in the battery, and electrolyte can directly impact the pole plate near the acid inlet tube mouth, causes the lead plaster on the pole plate to come off, and influences battery electrical property; Secondly, for the little battery of some volume, pole plate is nearer from the battery upper port, and acid inlet tube length can directly be inserted into pole plate, causes pole plate distortion and lead plaster to come off; These all can influence the electrical property of battery.Besides, this connector battery acid tube mouth of going out is higher than the acid inlet tube mouth, has objectively strengthened the circulate electrolyte output pressure, increases circulating consumption.In addition, connector does not have filter into and out of acid mouth in battery, easily causes in the battery bulky grain and lining paper mouthful to flow out from going out acid in the acid solution circulation, stops up circulating line when serious.Seal cover contacts entirely with the battery liquid filling hole, and frictional force is very big, not only difficult plug, and labour intensity is big, and very easily damages.Therefore still having is worth improved place.

The utility model content

The utility model purpose is to overcome the deficiency of above-mentioned prior art, provides a kind of improved storage battery that can effectively overcome above-mentioned prior art deficiency to change into electrolyte outer circulation connector.

The utility model purpose realizes, the main improvement is to raise the inside and outside feed liquor mouth of pipe of battery, make the inside and outside fluid mouth of pipe of battery all be lower than the feed liquor mouth of pipe, and increase screen pack outside the liquid in-out mouth in battery, concave ring groove in more than the seal cover side face is processed with together, thereby overcome the deficiencies in the prior art, realize the utility model purpose.Specifically, the utility model storage battery changes into electrolyte outer circulation connector, comprise seal cover that inserts the battery liquid-filling hole and the liquid in-out pipe arranged side by side that passes seal cover, it is characterized in that the integral body that seal cover and the liquid in-out pipe arranged side by side that passes seal cover are made of plastics, seal cover radially side face has the annular groove of placing sealing ring, the inside and outside feed liquor mouth of pipe of battery all is higher than the fluid mouth of pipe, and the liquid in-out mouth has filter in the battery.

The utility model storage battery changes into electrolyte outer circulation connector, more above-mentioned prior art has: because connector is made of plastics an integral body, liquid inlet and outlet pipe and sealing plug can not be shifted, and each battery keeps the high conformity of liquid level, operability is good, and the life-span is longer; And sealing plug radially side face has interior concave ring groove, can place the O RunddichtringO, has reduced plug frictional force, not only make plug become convenient, and plug can not damage sealing plug repeatedly yet, only need to change the O RunddichtringO, can use repeatedly for a long time, guarantee sealing, also prolong useful life; The feed liquor nozzle position is higher than the fluid nozzle position in the battery, on battery liquid level top, can avoid electrolyte directly to impact pole plate, and maintenance battery electrolyte inside level balance and consistency, and for volume little battery and the lower battery of electrolyte liquid level, can avoid acid inlet tube directly to be inserted into pole plate, cause pole plate distortion and lead plaster to come off; The liquid in-out mouth increases filtering screen in the battery, especially plug-in screen pack, both can play cushioning effect, do not allow electrolyte directly impact pole plate, avoid causing that lead plaster comes off, can play not allowing bulky grain in the battery, lining paper flow out the blocking pipe effect again, also help after filter screen stops up, extract cleaning and use repeatedly; The outer fluid nozzle position of battery is lower than the feed liquor nozzle position, can make electrolyte flow better by action of gravity, has reduced the systemic circulation energy consumption.

Below in conjunction with an embodiment; utility model is further understood in exemplary illustration and help; but the embodiment detail only is for utility model is described; do not represent utility model design whole technical schemes down; therefore should not be construed as the total technical scheme of utility model is limited; some are In the view of the technical staff; not departing from the unsubstantiality of utility model design changes; for example change or replace, all truely use novel protected scope so that technical characterictic with same or similar technique effect is simple.

Embodiment

Embodiment: referring to accompanying drawing, the utility model storage battery changes into electrolyte outer circulation connector, the sealing plug 1 that comprises hollow cylindrical tube 6 and insertion battery liquid-filling hole radially, both are integral by plastic injection-moulded, wherein hollow cylindrical tube 6 is divided into feed pathway arranged side by side 7 and liquid outlet channel 8 by longitudinal baffle with it, and the inside and outside feed pathway port of battery all is higher than the liquid outlet channel port, liquid in-out passage battery outer end has the connection mouth of pipe 2 and 3 of being with the retaining ring respectively.The sealing plug outer radial periphery has two road grooves 4, the interior O-ring seals of placing.There are two or above anticreep card release 9 in sealing plug battery the inner, and when making it can effectively prevent to change under non-external force, cell internal pressure be gone out connector.Cylinder flow liquid pipe end has plug-in screen cover 5 in the battery.

To those skilled in the art; under utility model design enlightenment; some distortion that can directly derive or associate from this patent disclosure, or the substituting of known technology commonly used in the prior art, and the mutual various combination between feature; for example the liquid in-out tube shape changes; the change of screen cover, or the like, can both realize and basic identical function of the foregoing description and effect; launch for example no longer one by one to describe in detail, all belong to this patent protection range.
