Problems solved by technology

Its shortcomings are: it cannot provide uniform temperature, humidity and wind speed, it cannot efficiently take out the heat generated by the oxidation of the plate, and the energy of water evaporation and the generated water vapor in the drying stage cannot meet the requirements
[0004] Therefore, in the existing production, there is a lack of a curing chamber that improves the curing efficiency of the plate stack

Embodiment 1

[0030] Such as figure 1 As shown, a curing chamber for solidifying lead-acid power battery plate stacks includes a curing chamber 1, and is characterized in that a partition wall 13 is provided in the curing chamber 1, and a partition wall 13 is provided between the two ends of the partition wall 13 and the curing chamber 1. There is an opening 14, and a partition wall 13 divides the curing chamber 1 into two connected tunnel cavities 15. The two tunnel cavities 15 are combined to form a ring-shaped tunnel. The curing chamber 1 is equipped with an internal circulation fan 2, and the ring-shaped tunnel is equipped with humidification equipment. 3 and several heat sources, the curing chamber 1 is provided with an air inlet 11 and an air outlet 12 that communicate with the outside world. Air outlet 12 and air inlet 11 are all provided with eight at intervals on the wall surface of curing chamber 1; The two sides of the curing chamber 1 are respectively arranged in groups of four...

Embodiment 2

[0033] Such as figure 2 and image 3 As shown, the difference between embodiment 2 and embodiment 1 is that the end of the partition away from the internal circulation motor is provided with a rectifying plate 4 arranged vertically on the partition, and 36 rectifying plates 4 are arranged in a 6*6 rectangular array. The stomata 41. An elastic membrane is arranged in the air hole 41, and a gap 42 is vertically arranged in the middle of the elastic membrane.

Embodiment 3

[0035] Such as Figure 4 As shown, the difference between embodiment 3 and embodiment 2 is that the upper and lower ends of the rectifying plate 4 are separately arranged from the upper and lower walls of the curing chamber 1, the outer ends of the rectifying plate 4 are slidingly connected with the curing chamber 1, and the rectifying plate 4 A surface shape set vertically for the axis. The outer end of the rectifying plate 4 is provided with a slide block 51, and the wall surface of the curing chamber 1 is provided with a slide rail 5 cooperating with the slide block 51. The slide rail 5 is arranged parallel to the bottom surface of the curing chamber 1, so that the rectifying plate 4 can be elastically deformed, and the rectifying plate The outer end of 4 can cooperate with slide rail 5 through slide block 51 and carry out translation.

[0036] In this application, the internal circulation fan 2 is used to provide the power for the circulation of the airflow. Since the mai...

Abstract

The invention discloses a curing room for curing lead-acid power battery polar plate laminates, which includes a curing room, and is characterized in that a partition wall is arranged in the curing room, and an opening is provided between the two ends of the partition wall and the curing room. The wall separates the curing room into two connected tunnel cavities, and the two tunnel cavities are combined to form a ring-shaped tunnel. The curing room is equipped with an internal circulation fan, and the ring-shaped tunnel is equipped with humidification equipment and several heat sources. Air port and air outlet. The advantage of the present invention is to adopt a brand-new circulation ventilation mode, change the original circulation ventilation system equipment into a heating auxiliary circulation system, make the indoor space receive heat energy evenly, maintain the uniformity of the indoor temperature, and improve the curing of the battery plate stacking method efficiency.

Description

technical field [0001] This application relates to the technical field of storage battery production, in particular to a curing chamber for curing lead-acid power battery plate stacks. Background technique [0002] The curing process is an important process in the production process of lead-acid batteries. Curing is a transfer process of evaporating water. In this process, there are physical changes and chemical changes. Its main function is to complete the hardening and corrosion of the lead paste, so that the lead paste The free lead is further oxidized and reduced, and at the same time, a good corrosion layer is formed between the lead paste and the grid, and the adhesion and cohesion in the dry-cured lead paste are further increased to achieve good mechanical strength and electrical properties. Therefore, The quality of plate curing is directly related to the overall performance of the plate and the final battery life. [0003] At present, in order to further improve th...
