Technical Field

The utility model relates to a battery technical field, concretely relates to lead accumulator adds sour kettle and adds sour kettle row.

Background

The lead accumulator is one with electrodes made of lead and its oxide and electrolyte solution of sulfuric acid. When the lead-acid battery discharges, the lead dioxide of the positive electrode and the spongy lead of the negative electrode are converted into lead sulfate; during charging, the lead sulfate of the positive electrode and the negative electrode is respectively converted into lead dioxide and spongy lead.

Formation is a key process in lead storage battery production, and positive active materials are converted into lead dioxide and negative active materials are converted into spongy lead through charging and discharging. There are two common formation methods, plate formation and battery formation. The acid adding pot is a container for storing sulfuric acid solution in the formation process of the battery. In the negative pressure or vacuum formation, the acid adding kettle needs to bear certain negative pressure and keep good sealing performance, and the acid adding kettle used in the normal pressure formation cannot meet the requirements of the negative pressure or vacuum formation.

The patent specification with the publication number of CN207719350U discloses that an acid adding kettle group comprises at least one acid adding kettle row group, the row head of the acid adding kettle row group is provided with a baffle, the baffle is of a square plate structure or an arc structure, the acid adding kettle row group is provided with 2 groups, the acid adding kettle group comprises a first acid adding kettle row group and a second acid adding kettle row group, the first acid adding kettle row group is parallel to the second acid adding kettle row group, and the first acid adding kettle row group is identical to the second acid adding kettle row group in structure.

The acid adding kettle of the scheme has poor sealing effect, is easy to leak gas, has poor buffering effect and is easy to damage the middle cover of the battery.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a lead accumulator adds sour kettle can not only prevent to add sour kettle gas leakage, can also effectively protect the lid in the battery.

The utility model provides a lead accumulator adds acid kettle, closes kettle body and pot lid including covering each other, the middle part of pot lid has the acid mouth that adds, the kettle body is kept away from pot lid one end and is provided with out the acid mouth, the top of pot lid is provided with the sealing washer, the middle part of sealing washer has the through-hole that supplies add the acid mouth and stretch into.

This scheme sets up the sealing washer through the top at the pot lid, can not only prevent sour kettle gas leakage, can also protect the well lid of battery jar, satisfies the sealed and buffering requirement that negative pressure or vacuolation become.

Preferably, a positioning structure is arranged between the kettle cover and the sealing ring, and the positioning structure comprises a plurality of positioning pins arranged at the top of the kettle cover and positioning holes arranged on the sealing ring and matched with the positioning pins.

Preferably, the height of the positioning pin is 1/4-1/2 of the thickness of the sealing ring.

Preferably, supporting rods distributed around the acid outlet nozzle are arranged at one end of the kettle body, which is far away from the kettle cover.

Preferably, the support rod is sleeved with a buffer sleeve.

Preferably, the acid outlet nozzle is sleeved with a rubber nozzle.

Another object of the utility model is to provide a lead accumulator adds sour kettle row, including a plurality of lead accumulator that set up side by side adds sour kettle, lead accumulator adds sour kettle for foretell lead accumulator adds sour kettle.

Preferably, the kettle cover and the sealing ring are respectively connected into a whole.

The utility model has the advantages that:

the utility model discloses on traditional lead accumulator acidification kettle basis, increased sealing washer and cushion collar, become the in-process in the vacuum, connect vacuum apparatus and battery, can have good sealed with vacuum apparatus, effectively protect the battery in the lid, satisfy the sealed and buffering requirement that negative pressure or vacumize to become.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-6, a lead storage battery acid adding kettle comprises a kettle body 1, wherein the top of the kettle body 1 is open and covered by a kettle cover 2, the bottom of the kettle body 1 is funnel-shaped, an acid outlet 3 is arranged at the bottom of the kettle body 1, and in the embodiment, a rubber nozzle 4 is sleeved on the acid outlet 3.

As shown in figure 1, the acid adding nozzle 5 is arranged in the middle of the pot lid 2, the sealing rubber groove 21 is arranged at the bottom of the pot lid 2 and used for being connected with the pot body 1, the sealing ring 6 is arranged at the top of the pot lid 2, and the through hole 61 for the acid adding nozzle 5 to extend into is arranged in the middle of the sealing ring 6. The kettle cover 2 and the sealing ring 6 are fixed through a positioning structure, specifically, three raised positioning pins 22 are arranged on the top of the kettle cover 2 around the acid adding nozzle 5, and a positioning hole 62 matched with the positioning pins 22 is arranged on the sealing ring 6; in this embodiment, the height of the positioning pin 22 is 1/4 of the thickness of the seal ring 6.
