Description

Technical Field

[0001] The utility model relates to the technical field of battery production, in particular to a battery internal formation water bath temperature control device. Background Art

[0002] Formation is a very important step in the manufacturing process of lead-acid batteries. The purpose of formation is to convert the solidified lead paste into a porous substance with electrochemical activity, namely PbO2 on the positive plate and sponge-like metal Pb on the negative plate. These active substances are connected to the grid in terms of mechanical strength and conductivity. There are two types of formation: external formation (tank formation) and internal formation (battery formation).

[0003] Battery formation is completed in a high electrolyte density, tight electrode group assembly, limited electrolyte volume and limited space volume. The internal formation environment temperature, formation current density, acid immersion time, etc. are all important factors affecting the performance of the electrode plate and the consistency of the battery after formation.

[0004] The patent document with application number CN202023299971.0 discloses a battery internal formation water bath temperature control device, which sets a water temperature control range, and a temperature sensor monitors the water bath temperature. When the water bath temperature is lower than the set lower limit, the water flow controller turns off the water flow, and the battery internal formation generates heat to increase the water bath temperature. When the temperature approaches the set upper limit, the water flow controller gradually opens the valve switch to increase the water flow. When the temperature exceeds the upper limit, the valve switch will be opened to the maximum, and the battery temperature will be lowered by heat exchange between water and the battery, thereby controlling the internal formation effect of the battery. Since a large number of storage batteries are placed in the formation tank, the formation tank itself is relatively large. When the water temperature of the formation tank is greater than the set stability, the water temperature in the formation tank with only a single cold water inlet pipe cannot be timely reduced to the set water temperature, resulting in uneven water temperature in the formation tank, and the battery in the formation tank cannot be timely cooled, and thus the formation quality of the battery cannot be effectively guaranteed. Utility Model Content

[0040] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0041] Example 1: Reference Figure 1-Figure 4As shown, a battery internal formation water bath temperature control device includes a water tank 1, and the water tank 1 is fixedly connected with an inlet pipe 3 and an outlet pipe 4. Specifically, the inlet pipe 3 and the outlet pipe 4 are respectively connected to the two ends of the water tank 1 in the length direction. The inner diameter of the outlet pipe 4 is larger than the inner diameter of the inlet pipe 3.

[0042] Two baffles 7 are fixed in the water tank 1. Two cooling pipes 6 are fixed in the water tank 1. The cooling pipes 6 are located above the baffles 7. The length direction of the cooling pipes 6 is parallel to the length direction of the baffles 7. A plurality of connecting pipes 10 are fixedly connected to the opposite sides of the two cooling pipes 6. The connecting pipes 10 are perpendicular to the cooling pipes 6.

[0043] A fixing rod 12 is fixed in the connecting tube 10, and an inner rod 13 concentric with the connecting tube 10 is fixed on the fixing rod 12. An inserting tube 11 is elastically and slidably sealed and inserted in the connecting tube 10. Specifically, a fixing ring 17 is fixed in the connecting tube 10, and the fixing ring 17 is connected to the inserting tube 11 through a spring 16.

[0044] One end of the cannula 11 away from the fixed rod 12 extends to the outside of the connecting tube 10, and one end of the inner rod 13 away from the fixed rod 12 extends into the cannula 11. A retaining ring 14 is concentrically fixed to one end of the inner rod 13 in the cannula 11. An inner ring 15 is fixed to one end of the cannula 11 in the connecting tube 10, and the inner rod 13 passes through the inner ring 15. The retaining ring 14 can block the cannula 11 after contacting the inner ring 15.

[0045] One end of the inserting pipe 11 outside the connecting pipe 10 is processed with an inclined surface, and the lower end of the inclined surface is inclined toward the middle direction of the water tank 1.

[0046] A temperature sensor 2 is fixed in the water tank 1. One end of the cooling pipe 6 is fixed in the water tank 1, and the other end of the cooling pipe 6 extends to the outside of the water tank 1. One end of the cooling pipe 6 outside the water tank 1 is fixedly connected to the manifold 5, and the manifold 5 is connected to the cooling water tank through a water pump. The water pump, the temperature sensor 2 and the controller are electrically connected.

[0047] During the process of the battery 8 being internally charged in the water tank 1 , the upper end of the battery 8 is plugged and connected to an acid pot 9 .

[0048] When the battery 8 is placed between the two baffles 7 in the water tank 1, after the lower end of the battery 8 contacts the inclined surface on the insertion tube 11, as the battery 8 continues to move between the two baffles 7, under the guidance of the inclined surface on the insertion tube 11, as the battery 8 moves downward, the insertion tube 11 moves into the connecting tube 10. After the insertion tube 11 moves into the connecting tube 10, the spring 16 is compressed, the retaining ring 14 is separated from the inner ring 15, and the insertion tube 11 is connected with the connecting tube 10.

[0049] The water temperature threshold in the water tank 1 during the internal formation process of the battery 8 is set in the controller. After the cooling water enters the water tank 1 from the inlet pipe 3, it is discharged from the outlet pipe 4. During the internal formation process of the battery 8, the cooling water in the water tank 1 can cool down the battery 8. When the temperature sensor 2 senses that the water temperature in the water tank 1 is greater than the set water temperature threshold, the controller starts the water pump, and the water pump makes the water in the cooling water tank enter the cooling pipe 6 and then is discharged from the interconnected cannula 11 and the connecting pipe 10 and directly flows to the battery 8. That is, the cooling water in the cooling pipe 6 can only be discharged through the connecting pipe 10 and the cannula 11 corresponding to the battery 8 and directly flows to the battery 8, which can timely cool down the battery 8, thereby ensuring the internal formation quality of the battery 8. When the temperature sensor 2 senses that the water temperature in the water tank 1 is lower than the set threshold, the controller turns off the water pump.

[0050] Since the inner diameter of the outlet pipe 4 is larger than that of the inlet pipe 3 , when the water pump is started to cool the battery 8 , the water in the water tank 1 can be discharged through the outlet pipe 4 in time, thereby preventing the water level in the water tank 1 from being too high and submerging the battery 8 .

[0051] After the battery 8 is placed between the two baffles 7, the insert 11 misplaced with the battery 8 does not move, that is, the connecting pipe 10 and the insert 11 misplaced with the battery 8 are not connected, and the cooling water will not be discharged from the insert 11 misplaced with the battery 8. The cooling water in the cooling pipe 6 can accurately flow to the battery 8, and the amount of cooling water can be saved when cooling the battery 8.

[0052] Embodiment 2: Based on Embodiment 1, refer to Figure 1 As shown, the inlet pipe 3 and the outlet pipe 4 are connected to the cooler. A flow valve 18 is installed on the inlet pipe 3, and the temperature sensor 2, the flow valve 18 and the controller are electrically connected.

[0053] In order to reduce the amount of cooling water used in this embodiment, a cooler is provided which is connected to the inlet pipe 3 and the outlet pipe 4. The water discharged from the outlet pipe 4 is cooled by the cooler and then flows back to the water tank 1 through the inlet pipe 3.

[0054] When the temperature sensor 2 senses that the water temperature in the water tank 1 is greater than the water temperature threshold set in the controller, the controller can increase the opening of the flow valve 18, thereby increasing the flow rate of the cooling water between the water tank 1 and the cooler, thereby reducing the temperature of the water in the water tank 1, and ultimately further improving the cooling efficiency of the battery 8.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
