Description

Technical Field

[0001] This utility model relates to the field of battery electrode production technology, specifically to a surface dryer for battery electrode production. Background Technology

[0002] During the processing of lead-acid battery plates, drying is required after curing. Since the battery plates are cured by water vapor, water droplets remain on the surface of the plates after curing. When drying, the plates with residual water droplets are directly placed into the dryer for heating and drying, resulting in slow drying speed, insufficient drying, and poor performance.

[0003] To address the aforementioned technical issues, patent document CN221223130U discloses a surface dryer for producing lead-acid battery plates, comprising a base, with chain conveyor belts installed at both ends of the top of the base, and a drainage mechanism located below one of the chain conveyor belts on the top of the base; a U-shaped frame with an opening facing downwards is installed on the top of the base between the two chain conveyor belts, with two scraper blades symmetrically installed between the U-shaped frames, and a strip-shaped mounting seat installed at the bottom of the U-shaped frame, with several fixing rods equidistantly installed on the top of the strip-shaped mounting seat and the inner top of the U-shaped frame, each fixing rod being fixed to the scraper blade. During use, the squeegee can remove excess water droplets from the surface of the battery plates. The battery plates are then transported to the drying chamber for drying. However, during the process of transporting the battery plates from one chain conveyor belt to another, the battery plates are prone to getting stuck between the two squeegees. In order to ensure that the battery plates are transferred on the two chain conveyor belts, the friction between the squeegee and the battery plates cannot be too great. Therefore, the effect of removing water droplets from the battery plates by squeegee is poor. Utility Model Content

[0004] The main purpose of this invention is to provide a surface dryer that can effectively remove water droplets from battery plates and improve drying efficiency.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A surface dryer for battery electrode plate production includes a box with openings at both ends. A conveyor belt is installed inside the box. A hot air device is installed on one side of the upper end of the box, which blows hot air onto the upper end of the conveyor belt. Two vertically arranged fixed pipes are fixed inside the box on one side of the hot air device. The upper straight part of the conveyor belt is located between the two fixed pipes. The axial direction of the fixed pipes is perpendicular to the conveying direction of the conveyor belt. Multiple nozzles are evenly distributed and fixed on the fixed pipes along their axial direction. The nozzles are connected to the fixed pipes, and the outlet ends of the nozzles face the conveyor belt. The pipe is connected to a pressurizing device fixed on the outside of the housing. The pressurizing device can pressurize the hot air in the housing below the hot air device and introduce it into the fixed pipe. Rotary shafts are rotatably connected to the housings on both sides of the upper fixed pipe. Multiple turntables are fixed on each of the shafts. The number of turntables on the two shafts is equal and corresponds one-to-one. The corresponding two turntables are connected by a conveyor belt. A motor is fixed on the housing and is connected to one of the shafts. The nozzles on the lower fixed pipe correspond to the upper and lower parts of the conveyor belt. The conveyor belt includes a rubber belt and a cotton cloth belt is fixed on the outside of the rubber belt.

[0007] Specifically, the hot air device includes a fan, a filter is installed at the inlet end of the fan, the outlet end of the fan is connected to the inlet end of the heater, the outlet end of the heater is connected to an air distribution plate fixed at the lower end of the top plate of the housing, and multiple air outlet holes are opened at the lower end of the air distribution plate.

[0008] Specifically, the pressurization device includes an air compressor fixed to the outside of the housing. The inlet end of the air compressor is connected to the housing part below the air distribution plate, and the outlet end of the air compressor is connected to two fixed pipes through a manifold.

[0009] Specifically, the nozzle of the fixed tube above is misaligned with the turntable.

[0010] Specifically, a water trough is provided at the upper end of the bottom plate of the box, and a drain pipe connected to the water trough is fixed on the bottom plate of the box.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. High-temperature compressed air is sprayed through nozzles in the upper and lower fixed tubes, directly impacting the surface of the battery plates. The nozzles on both sides work together to simultaneously remove residual water droplets from both sides of the plates, avoiding the insufficient physical contact problem of traditional wipers. The high-temperature compressed air preheats the battery plates while blowing away the water droplets, reducing energy consumption in subsequent drying stages. The staggered nozzle design expands the airflow coverage, reduces drying blind spots, and improves overall uniformity.

[0013] 2. The conveyor belt and conveyor mesh belt clamp the battery plates, while nozzles below blow air in the opposite direction onto the conveyor belt. This clamping and conveying prevents the battery plates from shifting due to airflow impact, ensuring continuous and stable transmission. A cotton cloth layer absorbs water droplets on the contact surface, enhancing the dehydration effect; hot air from nozzles below dries the cotton cloth belt, achieving self-cleaning circulation. The conveyor belt and mesh belt operate synchronously, adapting to the flexible conveying needs of battery plates of different thicknesses.

[0014] 3. The pressurization device recovers waste heat air from the chamber, repressurizes it, and supplies it to the nozzles. This waste heat recycling reduces energy waste and lowers system operating costs. The air distribution plate provides uniform and gentle hot air for final drying, while the high-pressure, high-temperature airflow from the nozzles is used for pre-drying, creating a gradient temperature field. A water tank at the bottom of the chamber quickly discharges desiccation water droplets, maintaining a stable drying environment.

[0015] 4. The hot air device and the pressurization device are independently external, which facilitates quick maintenance and replacement and reduces downtime.

[0016] 5. This technical solution is adaptable to various electrode materials such as lead-acid and lithium batteries, avoiding surface scratches or deformation. High-temperature airflow drying avoids water residue, improving the consistency of finished electrode products. The system operates stably and is suitable for continuous large-scale production scenarios. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1: Refer to Figures 1-4As shown, a surface dryer for battery electrode production includes a box 1 with openings at both ends, a conveyor belt 2 installed inside the box 1, and a hot air device on one side of the upper end of the box 1, which can blow hot air to the upper end of the conveyor belt 2.

[0025] A water trough is provided at the upper end of the bottom plate of the box 1, and a drain pipe connected to the water trough is fixed on the bottom plate of the box 1.

[0026] The hot air device includes a fan 3, a filter is installed at the inlet end of the fan 3, the outlet end of the fan 3 is connected to the inlet end of the heater 4, and the outlet end of the heater 4 is connected to an air distribution plate fixed at the lower end of the top plate of the housing 1. Multiple air outlet holes are opened at the lower end of the air distribution plate.

[0027] Two vertically arranged fixed pipes 7 are fixed inside the housing 1 on one side of the hot air device. The upper straight part of the conveyor belt 2 is located between the two fixed pipes 7, and the axial direction of the fixed pipes 7 is perpendicular to the conveying direction of the conveyor belt 2. Multiple nozzles 701 are evenly distributed and fixed on the fixed pipes 7 along their axial direction. The nozzles 701 are connected to the fixed pipes 7, and the outlet end of the nozzles 701 faces the conveyor belt 2. The fixed pipes 7 are connected to a pressurizing device fixed on the outside of the housing 1. The pressurizing device can pressurize the hot air in the housing 1 below the hot air device and introduce it into the fixed pipes 7.

[0028] The pressurization device includes an air compressor 5 fixed to the outside of the housing 1. The inlet end of the air compressor 5 is connected to the housing 1 part below the air distribution plate, and the outlet end of the air compressor 5 is connected to two fixed pipes 7 through a manifold 6.

[0029] The upper fixed tube 7 has rotating shafts 9 rotatably connected inside the boxes 1 on both sides. Multiple turntables 10 are fixed on the rotating shafts 9. The number of turntables 10 on the two rotating shafts 9 is equal and corresponds one to one. The corresponding two turntables 10 are connected by a conveyor belt 11. A motor 8 is fixed on the box 1 and is connected to one of the rotating shafts 9.

[0030] The nozzle 701 of the fixed tube 7 above is misaligned with the turntable 10.

[0031] When drying the surface of the battery plates, such as Figure 2As shown, the battery plates are evenly arranged on the upper left side of the conveyor belt 2, which then transports them to the right. The fan 3 and heater 4 are started; air filtered by the filter flows through the fan 3, heater 4, and air distribution plate before being blown onto the conveyor belt 2. The air compressor 5 is started, compressing the hot air inside the housing 1 and spraying it out through the manifold 6, fixed pipe 7, and nozzle 701. The motor 8 is started, driving the connected shaft 9 to rotate. Under the transmission action of the conveyor belt 11, the turntable 10 rotates. After the battery plates on the conveyor belt 2 enter between the conveyor belt 11 and the conveyor belt 2, they are held and transported by the conveyor belt 11 and the conveyor belt 2. Compressed air sprayed from the upper nozzle 701 blows away water droplets on the upper surface of the battery plates, and compressed air sprayed from the lower nozzle 701 blows away water droplets on the lower surface of the battery plates. The battery plates are held and conveyed by the conveyor belt 11 and the conveyor mesh belt 2, which prevents the compressed air ejected from the nozzle 701 from causing displacement of the battery plates. The battery plates can be stably conveyed when drying their surface. After the battery plates move to the bottom of the air distribution plate, the hot air discharged from the air outlet at the bottom of the air distribution plate can dry the battery plates.

[0032] The air compressor 5 compresses the hot air inside the housing 1 and then sprays it out through the manifold 6, the fixed pipe 7, and the nozzle 701. The compressed air sprayed from the nozzle 701 has a high temperature, which can pre-dry the battery plates while blowing away water droplets on the surface of the battery plates, further improving the drying efficiency of the battery plate surface.

[0033] The nozzle 701 of the upper fixed tube 7 is offset from the turntable 10, which can increase the contact area between the compressed air ejected from the upper nozzle 701 and the upper surface of the battery plate, thereby improving the effect of blowing off water droplets on the upper surface of the battery plate.

[0034] Example 2: Based on Example 1, referring to... Figure 4 and Figure 5 As shown, the nozzle 701 on the fixed tube 7 below corresponds vertically to the conveyor belt 11.

[0035] The conveyor belt 11 includes a rubber belt 110, and a cotton cloth belt 111 is fixed to the outside of the rubber belt 110.

[0036] When the battery plates are held and conveyed by the conveyor belt 11 and the conveyor mesh belt 2, the cotton cloth belt 111 of the conveyor belt 11 can absorb the water droplets on the contact surface of the battery plates, which can improve the effect of removing water droplets from the battery plates.

[0037] Since the nozzle 701 on the lower fixed tube 7 corresponds vertically to the conveyor belt 11, after the battery plate separates from the conveyor belt 11, the high-temperature compressed air sprayed from the lower nozzle 701 can blow towards the conveyor belt 11, thereby drying the cotton cloth 111 and ensuring the water absorption of the cotton cloth 111. After the cotton cloth 111 comes into contact with the next battery plate, it can continue to absorb the water droplets on the contact surface between the cotton cloth 111 and the battery plate.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
