Abstract

This utility model relates to the field of ion exchange membrane processing technology, and in particular to a device for spraying ion exchange membrane adhesive. It includes a base frame, a shock-absorbing device fixedly connected to the bottom of the base frame, casters fixedly connected to the bottom of the shock-absorbing device, a column support fixedly connected to the top of the base frame, and a connecting block fixedly connected to the side of the column support. The device incorporates components such as a first drive motor, a rotating rod, a stirring tank, turbulence-inducing blades, and turbulence-inducing grooves. The stirring tank, with its turbulence-inducing blades and turbulence-inducing grooves on the inner wall of the storage cylinder, is installed inside the storage cylinder.

During membrane module manufacturing, a specialized adhesive is typically applied to the junction of the membrane and the frame or sealing ring to achieve a strong seal. However, existing adhesive spraying devices suffer from several shortcomings: a lack of stable stirring, leading to easy settling or solidification of the adhesive in storage tanks or delivery pipes; uneven spraying; fixed spraying position, making it impossible to quickly adjust the nozzle position according to different ion exchange membrane specifications, resulting in spraying deviations; sensitivity to membrane material; and a lack of precise control over spraying pressure and spray particle size, potentially causing membrane surface damage.

[0021] The system includes components such as a first servo motor 7, a rotating rod 8, a stirring tank 29, turbulence blades 30, and turbulence grooves 31. The stirring tank 29 is located inside the glue storage cylinder 12, and the stirring tank 29 has turbulence blades 30. At the same time, the inner wall of the glue storage cylinder 12 has turbulence grooves 31. When the ion exchange membrane binder is injected into the glue storage cylinder 12 through the feed port 10, the first servo motor 7 starts to rotate, driving the stirring tank 29 to rotate. Meanwhile, the turbulence blades 30 on the stirring tank 29 generate more vortices in the binder, further agitating the binder and ensuring stable viscosity. Combined with the high-precision filter components, this effectively prevents the nozzle 24 from clogging.

[0022] In this embodiment, as Figure 3 and Figure 4As shown, a threaded rod 20 is provided inside the bearing base 19. A threaded slider 21 is sleeved on the outer wall of the threaded rod 20. An electric fine-tuning mechanism 22 is fixedly connected to the top surface of the threaded slider 21.

A driving gear 26 is provided at the bottom of the driven gear 27. The driving gear 26 and the driven gear 27 are meshed. A second servo motor 25 is provided on the side of the driving gear 26. The rotation output end of the second servo motor 25 is fixedly connected to the driving gear 26. The device is equipped with components such as a booster air pump 6, an electric fine-tuning mechanism 22, an atomization adjustment ring 23, and a nozzle 24. The booster air pump 6 can pressurize the glue storage cylinder 12, thereby increasing the pressure inside the glue delivery hose 15 and increasing the flow rate of the glue sprayed from the nozzle 24. At the same time, the electric fine-tuning mechanism 22 can control the contraction or expansion of the atomization adjustment ring 23, thereby controlling the degree of atomization of the glue sprayed from the nozzle 24, which greatly improves the adaptability of the device.

The lifting of the hydraulic lifting rod 16 allows the nozzle 24 to move up and down, while the forward and reverse rotation of the second servo motor 25 allows the threaded slider 21 to move left and right on the threaded rod 20. This allows the device to adapt to the spraying position requirements of ion exchange membranes of different specifications and shapes, reducing manual adjustment time.

[0025] The working process of this utility model is as follows: When using the device and structure designed in this scheme for spraying ion exchange membrane adhesive, firstly, the device is moved to the designated position, and then the ion exchange membrane adhesive is injected into the storage cylinder 12 through the feed port 10. The main controller 17 controls the first servo motor 7 to rotate, driving the stirring tank 29 to rotate. At the same time, the turbulence blades 30 on the stirring tank 29 generate more vortices in the adhesive, further agitating the adhesive. Simultaneously, the main controller 17 controls the hydraulic lifting rod 16 to position the nozzle 24 appropriately, and then controls the booster air pump 6 to pressurize the storage cylinder 12, thereby increasing the pressure in the adhesive delivery hose 15, which in turn increases the flow rate of the nozzle 24. At the same time, the electric fine-tuning mechanism 22 can control the contraction or expansion of the atomization adjustment ring 23, thereby controlling the degree of atomization of the adhesive sprayed from the nozzle 24 to meet various construction requirements.
