It aims to solve the problems that not only do traditional silicone defoamers hinder defoaming, but they also affect the effective bonding between RFL adhesive and fibers, reducing the adhesion between the fabric and rubber. Furthermore, they may generate volatile substances during high-temperature vulcanization, leading to defects such as white spots on the fabric surface and affecting the product's appearance. The key technical points are: a concave peripheral collection groove is provided on the guide edge; an inclined groove connected to the peripheral collection groove is fixedly provided on the outer edge of the guide edge; a defoaming tank fixed to the ground is provided below the end of the inclined groove; the top of the defoaming tank has an opening aligned with the end of the inclined groove; the defoaming tank is equipped with an adhesive return filtration system connected to the dipping tank body; and a defoaming device is installed in the defoaming tank. This achieves the effect of effectively reducing the bubble content in the adhesive, ensuring the quality of the finished product, while continuously filtering and recycling the adhesive.

Description

Technical Field

[0001] This utility model relates to the technical field of dipping equipment, specifically a dipping tank system with physical defoaming function. Background Technology

[0002] In the impregnation process of textile materials such as tire cord fabric, the traditional impregnation tank has a relatively simple structural design (e.g., no flow guide design or short overflow path). Due to high-speed stirring, fabric traction, and pump circulation, the adhesive solution in the tank is prone to generating a large number of tiny bubbles. To suppress foaming, chemical defoamers need to be continuously added during the impregnation process, with silicone-based defoamers being the most common. However, these defoamers have the following significant drawbacks: 1. Poor environmental performance: Silicone compounds are difficult to biodegrade and remain in large quantities in industrial wastewater, leading to an increased wastewater treatment load; 2. Impact on product performance: Silicone substances are easily adsorbed onto the fabric surface, not only hindering the effective bonding between the adhesive solution and fibers and reducing the adhesion between the fabric and rubber, but also potentially producing volatile substances during high-temperature vulcanization, causing defects such as white spots on the fabric surface and affecting the product's appearance; 3. Limited defoaming efficiency: In traditional impregnation tanks, the overflow adhesive solution is discharged directly through a narrow edge, resulting in a fast flow rate and short residence time, leading to weak defoaming effect, increasing production costs and environmental burden.

[0003] To address the aforementioned issues, this invention provides a defoaming and circulation device for an impregnation tank. Through structural improvements, it achieves physical defoaming and adhesive recycling, reducing the use of chemical defoamers and preventing white spots on the fabric surface. Utility Model Content

[0004] The purpose of this invention is to provide a dipping tank system with physical defoaming function.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The device includes a glue-impregnating tank body fixedly installed on the ground. A guide edge is fixedly installed around the top edge of the glue-impregnating tank body. The guide edge has a concave peripheral collection groove. An inclined groove connected to the peripheral collection groove is fixedly installed on the outer edge of the guide edge. A defoaming tank fixedly installed on the ground is provided below the end of the inclined groove. The top of the defoaming tank has an opening aligned with the end of the inclined groove. The defoaming tank is equipped with a glue return filtration system connected to the glue-impregnating tank body. A defoaming device is also installed in the defoaming tank.

[0007] By adopting the above technical solution, since the density of bubbles is much smaller than that of the adhesive, they will float on the surface of the adhesive. During use, the adhesive is continuously and slowly added to the impregnation tank. The adhesive containing bubbles at the top will overflow from the top edge of the defoaming tank and fall into the outer collection tank. Then, under the guidance of the guide side, it flows through the inclined trough and is finally collected in the defoaming tank for defoaming treatment. After defoaming treatment, the adhesive is returned to the impregnation tank for reuse under the action of the adhesive return filtration system. This effectively reduces the bubble content in the adhesive, ensures the quality of the finished product, and increases the recycling rate of the adhesive from 70% to 95%, reducing raw material waste.

[0008] Furthermore, the defoaming device includes several sets of ultrasonic bases installed on the outer wall of the defoaming tank, and ultrasonic rods that penetrate into the defoaming tank are fixedly installed on the ultrasonic bases.

[0009] By adopting the above technical solution, the ultrasonic rod is connected to an external controller and power supply for function and control. The ultrasonic rod can effectively eliminate bubbles in the adhesive through ultrasonic action. The ultrasonic rod in the defoaming tank is an existing technology product, which is quite common in the market and is very common in the defoaming of adhesives, so it will not be described in detail.

[0010] Furthermore, a perforated sieve plate is fixedly installed in the middle of the height direction of the defoaming tank, a vibrating motor is fixedly installed at the bottom of the defoaming tank, several sets of springs are fixedly installed on the bottom wall of the defoaming tank, and the ends of the springs are fixedly installed with mounting bases positioned on the ground.

[0011] By adopting the above technical solution, the porous sieve plate can effectively block the sinking of air bubbles and initially filter out large particulate impurities in the adhesive, thus effectively ensuring the cleanliness of the adhesive. The oscillating motor combined with the spring can continuously oscillate while stably installing the defoaming tank, accelerating the rate at which air bubbles rise and are eliminated.

[0012] Furthermore, the guide edge and the edge of the inclined groove are open and outwardly flared, and the outer collection groove is deep V-shaped.

[0013] By adopting the above technical solution, the outward-expanding edge can increase the capacity to hold the overflowing adhesive, and the deep V-shaped outer collection tank, due to its small bottom volume, can discharge more adhesive than a flat bottom, preventing adhesive from stagnating at the bottom.

[0014] Furthermore, the adhesive reflux filtration system includes a reflux pump fixedly installed on the outer wall of the bottom of the defoaming tank, a plate and frame adhesive filter connected to the outer wall of the impregnation tank, the reflux pump connected to the bottom wall of the defoaming tank, a reflux pipe connected to the reflux pump, and the end of the reflux pipe connected to the plate and frame adhesive filter.

[0015] By adopting the above technical solution, the reflux pump is connected to the bottom of the defoaming tank. Due to the obstruction of the porous sieve plate and the defoaming effect of the ultrasonic rod, the adhesive at the bottom of the tank has the highest degree of cleanliness after treatment. The reflux pump continuously pumps the adhesive through the plate and frame adhesive filter for filtration, and then returns it to the impregnation tank body for recycling. This achieves the function of continuous filtration and recycling of adhesive. The plate and frame adhesive filter is a commonly used adhesive filter in this industry, so it will not be described in detail.

[0016] In summary, the beneficial technical effects of this utility model are as follows:

[0017] 1. A defoaming tank and defoaming device are used to effectively reduce the bubble content in the adhesive and ensure the quality of the finished product;

[0018] 2. A reflux filtration system is adopted, which enables continuous filtration and recycling of the adhesive liquid;

[0019] 3. It adopts a oscillating motor and spring, which produces a continuous oscillation while stabilizing the defoaming tank, thus accelerating the rate at which bubbles rise and are eliminated. Attached Figure Description

Detailed Implementation

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-3 The present invention provides the following technical solution:

[0028] The system includes a glue-impregnation tank body 1 fixedly installed on the ground. A guide edge 2 is fixedly installed around the top edge of the glue-impregnation tank body 1. The guide edge 2 has a recessed peripheral collection groove 21. An inclined groove 3 connected to the peripheral collection groove 21 is fixedly installed on the outer edge of the guide edge 2. A defoaming tank 4 fixedly installed on the ground is located below the end of the inclined groove 3. The top of the defoaming tank 4 has an opening aligned with the end of the inclined groove 3. The defoaming tank 4 is equipped with a glue return filtration system 5 connected to the glue-impregnation tank body 1. A defoaming device 6 is also installed in the defoaming tank 4. Due to the inherent properties of the bubbles... The density is much smaller than that of the adhesive, so it floats on the surface of the adhesive. During use, the adhesive is continuously and slowly added to the impregnation tank body 1. The adhesive containing air bubbles at the top will overflow from the top edge of the defoaming tank 4 and fall into the outer collection tank 21. Then, under the guidance of the guide edge 2, it flows through the inclined trough 3 and is finally collected in the defoaming tank 4 for defoaming treatment. After defoaming treatment, the adhesive is returned to the impregnation tank body 1 for use under the action of the adhesive return filtration system 5. This effectively reduces the air bubble content in the adhesive, ensures the quality of the finished product, and increases the recycling rate of the adhesive from 70% to 95%, reducing raw material waste.

[0029] The defoaming device 6 includes several sets of ultrasonic bases 61 installed on the outer wall of the defoaming tank 4. The ultrasonic bases 61 are fixedly equipped with ultrasonic rods 62 that penetrate into the defoaming tank 4. The ultrasonic rods 62 are connected to an external controller and power supply for function and control. The ultrasonic rods 62 can effectively eliminate bubbles in the adhesive through ultrasonic action. The ultrasonic rods 62 in the defoaming tank 4 are existing technology products and are quite common in the market. They are very common in the use of adhesive defoaming, so they will not be described in detail.

[0030] A porous sieve plate 7 is fixedly installed in the middle of the height direction of the defoaming tank 4. A vibrating motor 8 is fixedly installed at the bottom of the defoaming tank 4. Several sets of springs 81 are fixedly installed on the bottom wall of the defoaming tank 4. The ends of the springs 81 are fixedly installed with mounting bases 82 positioned on the ground. The porous sieve plate 7 can effectively block the sinking of bubbles and initially filter out large particles of impurities in the adhesive, effectively ensuring the cleanliness of the adhesive. The vibrating motor 8, combined with the springs 81, can continuously vibrate while stably installing the defoaming tank 4, accelerating the rate of bubble rising and elimination.

[0031] The guide edge 2 and the inclined groove 3 have an open, outward-expanding shape, and the outer collection groove 21 is deep V-shaped. The outward-expanding edge can increase the capacity to hold the overflowing adhesive. The deep V-shaped outer collection groove 21 has a small bottom volume, so it can discharge more adhesive than a flat bottom, preventing adhesive from stagnating at the bottom.

[0032] The adhesive return filtration system 5 includes a return pump 51 fixedly installed on the outer wall of the bottom of the defoaming tank 4. A plate and frame adhesive filter 52 is connected to the outer wall of the impregnation tank body 1. The return pump 51 is connected to the inner bottom wall of the defoaming tank 4 and a return pipe 53 is connected to the return pump 51. The end of the return pipe 53 is connected to the plate and frame adhesive filter 52. The return pump 51 is connected to the bottom of the defoaming tank 4. Due to the obstruction of the porous sieve plate 7 and the defoaming effect of the ultrasonic rod 62, the adhesive at the bottom of the tank has the highest degree of cleanliness after treatment. It is continuously pumped by the return pump 51 through the plate and frame adhesive filter 52 for filtration, and then returned to the impregnation tank body 1 for recycling. This system plays a role in continuous filtration and recycling of adhesive. The plate and frame adhesive filter 52 is a commonly used adhesive filter in this industry, so it will not be described in detail.
