Description

Technical Field

[0001] The utility model belongs to the technical field of battery manufacturing, and particularly relates to an air knife and a water removal device. Background Art

[0002] In the production process of lead-acid batteries, the batteries need to be subjected to a water bath process to ensure the process requirements for charging and formation. However, after the water bath, there are many water stains on the surface of the battery. If the surface of the battery, especially the metal part, is in contact with water for a long time, electrochemical corrosion may occur. This corrosion will destroy the structure of the battery, reduce its performance, and may even cause a short circuit or failure.

[0003] At present, there are usually two ways to remove water stains on the surface of batteries. One is to wipe with a rag, which can be wiped manually with a rag, or by placing rags along the conveyor line to wipe the moisture off the battery surface during the battery conveying process. However, not only is manual wiping inefficient, but repeated wiping with a rag can easily cause dirt and scratches on the battery surface.

[0004] Another method is to install wind knives on the conveyor line, and use the wind knives to blow out airflow at a certain pressure to dry the water stains on the surface of the battery without causing quality defects such as scratches on the battery surface, which has been widely used. For example, the Chinese utility model patent with publication number CN210569786U discloses a blow dryer. By understanding the description and the accompanying drawings, it can be seen that the blow dryer uses high-pressure airflow to remove water from the outside of the target object, and can continuously remove water from the target object without stopping the conveyor belt of the production line. However, in this solution, there are many wind knives installed, the structure is complex, and the air output of the wind knives cannot be adjusted. Continuous blowing causes a large waste of energy.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] In the description of the present invention, it should be understood that terms such as "end", "upper", "lower", "side", "top", "bottom", "length", "inside", and "surface" indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limitations on the present invention.

[0031] During the production process of batteries, there are many water stains attached to the surface of the batteries. The surface of the battery, especially the metal part, may be electrochemically corroded if it is in contact with water for a long time. This corrosion will damage the structure of the battery, reduce its performance, and may even cause a short circuit or failure. The current mainstream method of dehydration is to use an air knife to blow away the water on the surface of the battery. However, air knife dehydration devices have complex structures, and the air output of the air knife cannot be adjusted. Continuous blowing causes a large waste of energy. Based on this, the present embodiment provides a dehydration device.

[0032] See also Figure 1-Figure 2 As shown, the dewatering device includes a conveyor line 100 and a frame 200 installed on the conveyor line 100. Three air knives 300 are installed on the frame 200, including two side air knives and one top air knife. The two side air knives blow air from both sides of the conveyor line 100 to remove water from both sides of the battery, and the top air knife blows air from above the battery to remove water.

[0033] The blowing directions of the two side wind knives form an angle with the length direction of the conveyor line 100. When the battery is conveyed along the conveyor line 100, the wind can blow to the front end surface of the battery when the battery approaches the rack 200; similarly, when the battery moves away from the rack 200, the wind can blow to the rear end surface of the battery.

[0034] In this embodiment of the present invention, the wind knife 300 is improved as follows. Figure 3-Figure 6 As shown, the air knife 300 includes a housing 1, an air inlet 2 is opened on one side of the housing 1, an air outlet 3 is opened on the other side of the housing 1, and an air cavity is provided in the housing 1. Mounting rods 9 are fixed at both ends of the housing 1, and the mounting rods 9 are threaded rods, which cooperate with nuts to fasten the entire air knife 300 to the frame 200.

[0035] A piston 4 is provided in the cavity of the housing 1 and can slide along the inner wall of the housing 1. The shape of the piston 4 matches the inner wall of the housing. Two sealing grooves 401 are provided around the piston 4. Sealing rings are installed in the sealing grooves 401, so as to effectively adjust the size of the air cavity in the kowtow head 1 and the size of the air outlet 3.

[0036] A piston rod 5 is fixedly connected to one surface of the piston 4, and one end of the piston rod 5 away from the piston 4 extends out of an end surface of the housing 1. A guide slot 8 is provided on the end surface of the housing 1, and the piston rod 5 is slidably matched with the guide slot 8.

[0037] In a possible implementation scheme of the first embodiment, a plurality of adjustment holes 501 are opened on the circumferential side of the piston rod 5 along the length direction, and a through hole is opened on the circumferential side of the guide slot hole 8. The adjustment hole 501 is connected to the through hole through a latch 7 to fix the piston rod 5, thereby fixing the position of the piston 4 in the housing 1.

[0038] In addition, one end of the piston rod 5 extending out of the housing 1 is fixedly connected to a handle 6 to facilitate pushing and pulling the piston 4 .

[0039] In a preferred implementation scheme of the first embodiment, a pressure regulating valve is provided at the air inlet 2 .

[0040] When in use, adjust the position of the piston 4 of the wind knife 300 on both sides according to the height of the battery, and adjust the position of the piston 4 of the wind knife 300 on the top according to the width of the battery. The wind knife 300 is adjusted as follows:

[0041] Pull out the latch 7, push and pull the piston rod 5, adjust the air cavity and the air outlet 3 to a suitable size, insert the latch 7, and lock the adjustment hole 501. Each adjustment hole 501 corresponds to an air pressure value, that is, the air intake pressure needs to be adjusted by the pressure regulating valve to ensure that the air pressure blown out of the air outlet 3 is stable.

[0042] For example, if the size of the battery to be dehydrated becomes smaller, the piston 4 is pushed into the housing 1. If the air pressure of the intake air remains unchanged, the wind pressure blown out of the air outlet 3 becomes larger and the wind speed becomes faster, which may even blow the battery out of place or overturn, causing quality problems. Therefore, it is necessary to reduce the intake pressure at the air inlet 2 through the pressure regulating valve, so that the air cavity pressure before and after the adjustment of the piston 4 and the wind pressure blown out of the air outlet 3 tend to be stable, so as to adapt to the dehydration of batteries of different specifications and sizes, and achieve good use effect.
