Problems solved by technology

However, asphalt is greatly affected by temperature and is easy to age. Therefore, using asphalt as a sealing material will greatly reduce the sealing performance of the battery, and when the battery is stored, there will be phenomena such as electro-hydraulic loss and slurry paper crystallization, which will make the The capacity of the battery decreases and the discharge time shortens, which affects the service life of the battery. Therefore, the quality of the seal plays a key role in the quality of the zinc-manganese dry battery.
[0003] In addition, in the production process of batteries with asphalt as the sealing layer, before casting the asphalt sealant, it is necessary to lay a layer of wax paper cover as the attachment support of the asphalt. Manual operation is required in this process. At the same time, the wax paper cover The preparation of punching and sealing agent requires a lot of manual operation, and the material cost and labor cost are relatively large.

Embodiment 1

[0040] like Figure 1 to Figure 3 It shows that a structurally improved zinc -manganese dried battery in this embodiment includes zinc cylinder 1. Polycin paper 9, base 2, isolation tablets, carbon rods 5, sealing unit, positive hat 10 and block cover 11Paper 9 is set up between the positive pole material 3 and the zinc cylinder 1, which is set on the surface of the positive pole material 3, which is inserted in the middle of the positive pole material 3 and and the central part of the positive pole material 3 and the part of the positive pole material 3 and the part of the positive pole material 3 and the part of the positive pole material 3 and the part of the positive pole material 3 and the central part of the positive pole material 3, andPass through the isolation piece 4, the sealing unit is set on the exposed end of the carbon rod 5 and seal the opening end of the zinc tube 1, which is the end of the positive hat 10 to the end of the carbon rod 5.The ministry is also located...

Embodiment 2

[0048] like Figure 4 The difference between the embodiments and the embodiment one is that the outer grooves 8 inwardly depressed in the interior of the zinc cylinder 1 and the conversion 621 connection in the embodiments of this embodiment.The groove 8 on the surface of the zinc tube 1 causes the internal protruding structure of the zinc cylinder 1. When the sealing ring 6 kale is put into the zinc cylinder 1, the convex 621 is closely fitted with the protruding structure, which can better improve the sealing ring.6 sealing and sealing, and the raised structure has a better positioning effect on the sealing ring 6 on the Links 621.

[0049] The other structure of this embodiment is the same as the embodiments, and I won't go into details here.

Embodiment 3

[0051] The preparation process of an embodiment -one structural improved zinc -manganese dry battery, which includes the following process steps:

[0052] A. Pull the zinc chip processing into a zinc tube at one end;

[0053] B. Fix the opening of the zinc tube 1 in the step A, and press the base of the base 2 through the opening to the bottom of the zinc tube 1;

[0054] C. Put the inner wall of the zinc cylinder 1 in step B. Passion -layer paper 9;

[0055] D. Fill in the positive electrode material 3 in the zinc cylinder 1 in step C, and the depth of the compression depth of the positive electrode material 3 is 13 ~ 15mm;

[0056] E. Pay isolation tablets 4 in the upper surface of the positive pole material 3 in step D;

[0057] f. Pass the carbon rod 5 through the isolation tablet 4 in the step E and insert it into the positive electrode material 3;

[0058] G. Plugs at the outer peripheral 62 and the lower end of the sealing circle 6 and the lower end of the hole 64;

[0059]...

Abstract

The invention relates to the technical field of dry batteries, and in particular relates to a zinc-manganese dry battery with an improved structure and a preparation process of the zinc-manganese dry battery. The zinc-manganese dry battery comprises a zinc cylinder, pulp paper, a base, a positive electrode material, an isolation sheet, a carbon bar, a sealing unit, a positive electrode cap and a cover, wherein the sealing unit is a sealing ring; the sealing ring comprises a central column, a peripheral part and a connecting sheet; the central column is arranged in the center of the sealing ring; the peripheral part is arranged at the edge of the sealing ring; the connecting sheet is connected with the central column and the peripheral part; a through hole through which the carbon bar penetrates is formed in the central column; and the lower end of the through hole is gradually expanded outwards. The lower end of the through hole is gradually expanded outwards, so that the size of the lower part of the through hole is slightly greater than that of the upper part of the through hole, providing coating space in the through hole for a sealant, the carbon bar can be well aligned with the through hole during penetration, is convenient to install, and can be prevented from being scratched when being aligned with the through hole and penetrating through the through hole, so that assembling is facilitated. According to the preparation process, the production process is simplified, and the production cost and the labor cost are reduced.

Description

Technical field [0001] The invention involves the field of dry battery technology and especially involves a zinc -manganese dry battery with improved structural improvement. Background technique [0002] With the development of science and technology, carbon batteries have developed into a large family. There have been many kinds of common zinc-manganese dry batteries.The zinc -manganese dry battery is an original battery in the chemical power supply. It is a disposable battery. It is composed of battery components such as positive electrode materials, zinc cylinder, copper hat, carbon rods containing electrolytes.The negative electrode iron bottom, the positive electrode material is inserted with a carbon rod, the carbon rod has a copper hat, there is a pulp paper isolation layer between the positive electrode material and the zinc tube.Paper pads and asphalt are used as a sealing layer.However, asphalt is greatly affected by temperature, and it is easy to aging. Therefore, asph...
