Abstract
Description
Technical Field
[0001] The utility model relates to the field of filter paper production, in particular to a scale inhibitor powder coating device. Background Art
[0002] Scale inhibitor powder is a chemical substance used to prevent the formation of water scale and is widely applied to equipment such as water treatment, boilers, cooling towers, etc. Uniformly applying the scale inhibitor powder onto the wet filter paper is a crucial step because the combination of the filter paper and the scale inhibitor powder can effectively release the scale inhibitor components when water flows through, thereby preventing the formation of water scale. However, in the existing production processes, there are still many challenges in uniformly and firmly attaching the scale inhibitor powder to the wet filter paper.
[0003] Traditional methods for applying scale inhibitor powder usually adopt gravity spreading or simple spraying methods. These methods often fail to achieve uniform distribution of the powder on the wet filter paper, resulting in excessive scale inhibitor powder in some areas while too little or none in other areas. This uneven distribution seriously affects the scale inhibition effect of the filter paper, may lead to local generation of water scale in water treatment equipment, and reduces the overall operating efficiency of the system.
[0004] In addition, the weak adhesion between the scale inhibitor powder and the wet filter paper is also a major problem in the existing technology. During subsequent processing, transportation, and use, the scale inhibitor powder is prone to falling off from the filter paper, resulting in unstable scale inhibition effects. To increase the adhesion of the powder, additional adhesives or mechanical pressing equipment are usually required, which not only increases the production cost but may also affect the chemical activity of the scale inhibitor powder and reduce its actual effect.
[0005] In practical applications, the effective distribution and adhesion of the scale inhibitor powder are crucial for ensuring the scale inhibition performance of the filter paper. Therefore, the existing technology urgently needs a solution that can improve the uniformity and adhesion of the scale inhibitor powder to enhance the product quality and usage effect.

[0018] The present invention will be described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those of ordinary skill in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.
[0019] Embodiment 1
[0020] AsFigure 1 As shown in the figure, the utility model is a scale inhibitor powder coating device, which is arranged between the wet cloth and the oven and is used to transport the wet filter paper material towards the oven. The scale inhibitor powder coating device includes: a conveyor belt 1, a powder distribution box 2, and a capillary discharge pipe 3. The wet filter paper material is transported on the conveyor belt 1. The powder distribution box 2 is connected above the conveyor belt 1 through a bracket. The feed port of the capillary discharge pipe 3 is communicated with the powder distribution box 2, and the discharge port of the capillary discharge pipe 3 is above the conveyor belt 1 and close to the wet filter paper material on the conveyor belt 1. A blowing inlet 6 is arranged on the powder distribution box 2. While injecting scale inhibitor powder into the powder distribution box 2, compressed air is blown into the blowing inlet 6, so that the powder in the powder distribution box 2 is evenly blown into the capillary discharge pipe 3 and blown onto the wet filter paper on the conveyor belt 1 along the capillary discharge pipe 3. By using the conveyor belt 1 to transport the wet filter paper material and evenly distribute the powder on it at the same time, the whole production process can be automated, reducing manual intervention, improving the uniformity of powder distribution, and improving the production effect at the same time.
[0021] Furthermore, the powder distribution box 2 is communicated with a powder box 5 through a suction machine 4. The powder box 5 is used to store powder. The suction machine 4 is connected to the top of the powder distribution box 2 and is used to feed the powder in the powder box 5 into the powder distribution box 2. The powder diffuses in the powder distribution box 2. At this time, when compressed air is blown in, the diffused powder can be evenly blown into the capillary discharge pipe 3.
[0022] In this embodiment, the inlet of the capillary discharge pipe 3 is at the lower left of the powder distribution box 2, and the blowing inlet 6 is on the right side of the powder distribution box 2 and above the inlet of the capillary discharge pipe 3. When compressed air is blown in from the right side, an air flow from right to left will be formed in the powder distribution box 2. This air flow can effectively guide the powder to flow towards the inlet of the capillary discharge pipe 3, ensuring that the powder can smoothly enter the capillary discharge pipe 3 and avoiding the retention or accumulation of powder in the distribution box.
[0023] Furthermore, the capillary discharge pipe 3 is inclined and arranged at an angle with the conveyor belt 1. The inclined capillary discharge pipe 3 uses the action of gravity to promote the powder to flow downward along the pipe, making it easier for the powder to be evenly blown from the inlet to the outlet, reducing the residence time of the powder in the pipe, and improving the powder conveying efficiency.
[0024] In one implementation, the design of the inclined capillary discharge pipe 3 can flexibly adjust the inclination angle according to different production conditions to achieve different powder conveying rates and distribution effects.
[0025] In this embodiment, the capillary discharge pipe 3 is composed of multiple pipe fittings, and the pipe fittings are arranged side by side. The multiple side-by-side pipe fittings can more accurately distribute the powder to different areas of the wet filter paper through their respective discharge ports. Each pipe fitting is responsible for a part of the area, thus avoiding the situation where a single pipe cannot cover the entire filter paper surface and improving the overall distribution uniformity.
[0026] In one embodiment, different powder conveying distribution effects can be achieved by adjusting the distance between pipe fittings.
[0027] Example 2
[0028] This Example 2 is completed based on Example 1. Specifically, the conveyor belt 1 is set as a hollow structure, and a negative pressure device 7 is arranged below the conveyor belt 1, and the negative pressure device 7 is below the discharge port of the capillary discharge pipe 3; through its vacuum negative pressure, the powder is strongly adsorbed on the wet filter paper, improving the adsorption effect of the powder, making the powder not easy to fall off, thereby improving the quality of the final product; at the same time, the powder will not be wasted due to shedding or scattering, improving the material utilization rate and reducing the production cost.
[0029] Working principle: While the wet filter paper is conveyed from the wet cloth station to the oven station through the conveyor belt 1, the powder in the powder box 5 is sucked into the powder distribution box 2 by the suction machine 4; at the same time, compressed air is blown into the powder distribution box 2 to evenly blow the powder in the powder distribution box 2 into the capillary discharge pipe 3 and fall onto the wet filter paper on the conveyor belt 1 along the capillary discharge pipe 3; at the same time, the negative pressure device 7 works to generate a vacuum negative pressure to strongly adsorb the powder on the wet filter paper.
