Description

Technical Field

[0001] The utility model relates to the technical field of storage batteries, in particular to an acid adding device for producing lead-acid storage batteries. Background Art

[0002] The electrolyte used in lead-acid batteries is diluted acid. In the production of valve-regulated sealed lead-acid batteries, acid needs to be added to the battery before it is poured into the battery. In the production process of lead-acid batteries, acid is added to the battery through an acid adding machine.

[0003] At present, the acid adding methods are roughly divided into the following methods: 1. Insert the acid adding pot into the acid adding port of the battery, and then inject the acid into the acid pot with an injection tube. However, the alignment and insertion of the acid guard are all manual operations. When the acid pot is pulled out, there is residual acid in the acid pot, which is easy to splash onto the operator, posing a safety hazard; 2. Align the acid adding port of the battery with the injection tube. One method is to lower the injection tube to close the acid adding port to inject the acid, and the other method is to suspend the injection tube in the air and align it with the acid adding port to inject the acid. However, the distance requirement is relatively strict. If the distance is too far, it is easy to cause acid splashing, and if the distance is too close, it is easy to be damaged by collision. In addition, after the acid adding is completed, a little acid will remain in the injection tube, and when the injection tube is lifted, it will drip on the surface of the equipment, which not only causes a waste of acid, but also poses a safety hazard. Utility Model Content

[0004] The purpose of the utility model is to provide an acid adding device for lead-acid battery production in view of the deficiencies in the prior art. By arranging a reversible sealing baffle, after the acid adding is completed, the sealing baffle reduces the dripping of acid and collects it; by arranging an elastic sleeve, the effect of preventing the acid from splashing is achieved; and the elastic sleeve has a buffering effect, preventing the injection tube and the battery from being easily damaged by collision; in addition, the splashed acid can be collected to reduce resource waste.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an acid adding device for lead-acid battery production, comprising a frame, on which a conveying mechanism for conveying batteries and an acid adding mechanism for adding acid to batteries are arranged, as well as a lifting mechanism for driving the acid adding mechanism. The conveying mechanism, the acid adding mechanism and the lifting mechanism are structures of acid adding devices in the prior art, and will not be described in detail here; the acid adding mechanism comprises an injection tube, the outer end of the injection tube is plugged and fixed with an elastic sleeve, the side of the injection tube is provided with a through groove and a groove, and a sealing member for sealing is installed in the through groove. A self-sealing component of a closed frame, the self-sealing component includes a flip plate rotatably connected to the through groove, one end of the flip plate is fixedly connected to a counterweight end, and the other end of the flip plate is fixedly connected to a sealing plate that is adapted to the shape and size of the tube. When the acid in the frame is transported downward, the acid impacts and opens the sealing plate. By arranging a counterweight end at one end of the flip plate and a sealing plate at the other end of the flip plate, when the acid in the injection tube is transported downward, the transported acid impacts and opens the sealing plate, and acid addition begins; when the injection tube stops transporting the acid, the sealing plate is not impacted and is reset, thereby stopping acid addition.

[0006] Optionally, the sizes of the sealing plate and the through groove are adapted to each other, and a first liquid groove is opened on the inner surface of the sealing plate. By opening the first liquid groove on the sealing plate, when the sealing plate is closed, the acid dripping from the injection tube drips into the first liquid groove. When adding acid to the next battery, the sealing plate is impacted and flipped over. At this time, the acid in the first liquid groove is poured out and filling continues, thereby reducing waste.

[0007] Optionally, a plurality of detachable counterweight bolts are installed on the counterweight end, a plurality of screw grooves are opened on the surface of the counterweight end, and the plurality of screw grooves are threadedly fixed to a plurality of counterweight bolts. By setting the counterweight bolts, the number of counterweight bolts on the counterweight end can be increased or decreased according to the size of the acid impact to achieve a suitable flipping effect.

[0008] Optionally, the outer edge of the elastic sleeve is bent inward to form a second liquid tank, and a collecting tube is connected to the second liquid tank, and the collecting tube is connected to an external collecting device. By setting the elastic sleeve, when the injection tube moves downward, the elastic sleeve can be used to connect the injection tube and the acid filling port of the battery, which has a low distance requirement and can prevent acid from splashing. The elastic sleeve has a buffering effect to prevent the injection tube and the battery from being easily damaged by collision. In addition, the splashed acid can be collected to reduce resource waste.

[0009] Optionally, the frame has four-sided grooves, the size of the sealing plate is smaller than that of the four-sided grooves, and soft fillers are provided on the sides of the sealing plate. The fillers are sponges or other fillers, which improve the sealing effect of the sealing plate without affecting the activity of the sealing plate.

[0010] Optionally, both ends of the counterweight are elastically mounted with protruding rods, and the protruding rods are slidably matched with the slide grooves provided on the inner wall of the counterweight end. By setting the slide grooves and protruding rods, during installation, the protruding rods are pressed inwards and then inserted into the slide grooves.

[0011] Optionally, the bottom of the frame gradually expands outward to form an inclined surface. By setting the bottom of the frame as an inclined surface, it is convenient for the acid liquid at the nozzle of the injection tube to slide along the inclined surface and fall into the elastic sleeve.

[0012] The beneficial effects of the utility model are:

[0013] (1) The utility model provides a counterweight end at one end of the flip plate and a sealing plate at the other end of the flip plate. When the acid in the injection tube is transported downward, the transported acid impacts and opens the sealing plate, and acid addition begins.

By providing a first liquid tank on the sealing plate, when the sealing plate is closed, the acid dripping from the injection tube drips into the first liquid tank. When acid is added to the next battery, the sealing plate is impacted and flipped. At this time, the acid in the first liquid tank is poured out and filling continues, thereby reducing waste.
