Problems solved by technology

At present, the acid pouring pipe has many openings and is long in length, and plates of different widths are coated, which will cause waste of sulfuric acid
Similarly, the amount of acid leaching is uncontrollable, which will cause poor acid saturation on the surface of the plate and affect the quality of the plate. At the same time, too much acid leaching will cause excessive waste lead sludge, which wastes recycling and reuse costs.

Embodiment approach 1

[0017] This embodiment provides a battery smear flow adjustable acid shower device, such as figure 1 As shown, it is mainly made up of frame 1, main pipe 2, pressure roller 3 and driving wheel 4, the driving wheel 4 with the second polyester cloth 17 on the surface is fixed on the frame 1 through its rotating shaft 401 rotation, and the surface is covered with The pressure roller 3 with the first polyester cloth 16 is arranged on the top of the driving wheel 4, and the rotation axis 301 of the pressure roller 3 is parallel to the rotation axis 401 of the driving wheel 4. 3, the driving wheel 4 is tangent to the outer surface of the pressure roller 3; the two ends of the rotating shaft 301 of the pressure roller 3 are respectively fixed on a shaft sleeve 7, and the two shaft sleeves 7 are respectively sleeved on the bottom of a guide column 8 , the two guide posts 8 are parallel to each other and perpendicular to the rotating shaft 301 of the pressure roller 3, the bottom ends ...

Embodiment approach 2

[0020] This embodiment is a further improvement of Embodiment 1. The main improvement is that in Embodiment 1, when the electrode plate 10 to be soaked with acid enters between the pressing roller 3 and the driving wheel 4, due to the rotation axis of the driving wheel 4 If the position of 401 is fixed, the rotating shaft 301 of the pressure roller 3 will be driven by the shaft sleeve 7 and move up along the two guide posts 8 by a distance of the thickness of the electrode plate 10 to be soaked with acid, so that the electrode plate 10 to be soaked with acid can be allowed to enter the pressure roller 3 and the driving wheel 4; in the process of moving up, the pressure roller 3 will vibrate violently, and the rotating shaft 301 of the pressure roller 3 will be damaged after long-time use, which will affect the service life of the whole device.

[0021] Therefore, in this embodiment, if figure 2 On the two guide posts 8, between the positioning plate 12 and the bushings 7 on b...

Embodiment approach 3

[0024] This embodiment is a further improvement of Embodiment 2. The main improvement is that in Embodiment 2, when the electrode plate 10 to be soaked with acid moves out from between the pressure roller 3 and the driving wheel 4, both sides of the pressure roller 3 The shaft sleeve 7 drives the rotating shaft 301 and the pressing roller 3 to move down along the guide column 8. During the downward movement, the pressing roller 3 will also vibrate violently, which will damage the rotating shaft 301 of the pressing roller 3 after a long time of use, affecting the entire body. The service life of the device.

[0025] Therefore, in this embodiment, if image 3 A second buffer spring 15 is respectively sleeved between the two shaft sleeves 7 and the two fixing seats 9 . When the electrode plate 10 to be soaked with acid moves out from between the pressure roller 3 and the driving wheel 4, the bushings 7 on both sides of the pressure roller 3 will drive the rotating shaft 301 and ...

Abstract

The invention relates to the field of battery plate smearing, and discloses an acid leaching device capable of adjusting the flow of storage battery smearing, wherein an acid leaching main pipe is horizontally fixed on a frame, and one end of the acid leaching main pipe is provided with an acid inlet. A number of acid leaching branch pipes, which have vertical downward acid outlets, are communicated with the acid leaching main pipe and are arranged in the length direction of the acid leaching main pipe, are arranged below the acid leaching main pipe. A flow regulating valve is installed on each acid leaching branch pipe. A pressing roller is arranged just below the acid outlet of each acid leaching branch pipe. Two ends of a rotating shaft of each pressing roller are respectively fixed ona sleeve, and the two sleeves respectively sleeve the lower part of a guide column, and the bottom ends of the two guide columns are fixed on the frame through a fixing seat. A driving wheel is arranged below the pressing roller, and when a plate to be acid-leached enters between the driving wheel and the pressing roller, the outer surfaces of the driving wheel and pressing roller are tangential to each other. The device can close excess acid pipes according to the width of the plate, and can adjust the amount of acid leaching, the acid leaching saturation and product quality of the plate surface can be ensured, and the generation of waste lead mud is reduced.

Description

technical field [0001] The invention relates to the field of battery polar plate smears, in particular to an acid leaching device with adjustable flow rate for battery smears. Background technique [0002] During the manufacturing process of battery plates, the paste-coated plates need to be rolled and corrected by acid-drenched rollers again, and a layer of sulfuric acid is coated on the surface of the lead paste of the plates. The pressure roller is covered with polyester cloth, and there is an acid pouring pipe on it for acid soaking. The purpose of acid pouring is to form a thin layer of lead sulfate on the surface of the lead plaster of the electrode plate to prevent the surface of the electrode plate from sticking to each other after drying. , while avoiding plate surface cracks. At present, the acid pouring pipe has many openings and is long in length, and plates of different widths are coated, which will cause waste of sulfuric acid. Similarly, the amount of acid l...
