Abstract
Description
Technical Field
[0001] The utility model relates to a filter paper production technology, in particular to a humidification technology before the production of corrugated filter paper. Background Art
[0002] Corrugated filter paper is a kind of filter paper with a pleated structure. It is widely used in the automotive industry, water treatment industry, pharmaceutical industry and food and beverage industry. For example, it is used to make filter elements for automotive air filters or fuel filters.
[0003] During the production process, corrugated filter paper must be humidified before it is folded into a corrugated form. Folding the flat filter paper without humidification can easily cause cracks or damage during the folding process, and the unhumidified flat filter paper is more likely to rebound after folding. The humidified flat filter paper is then folded by a corrugator to form the corrugated filter paper.
[0004] Current equipment for humidifying flat filter paper consists of a water tank with a lid and a central hole for the filter paper to pass horizontally through. The water level in the tank is kept below the hole. The water in the tank is heated (e.g., using an electric heater) approximately 30 minutes before production, causing it to boil and generate steam. The flat filter paper then passes horizontally through the hole above the water level, becoming humidified as it passes through the tank. This humidification technology has the following drawbacks:
[0005] 1. If water needs to be heated 30 minutes in advance, someone needs to perform the heating operation 30 minutes in advance, which increases labor intensity and reduces production efficiency.
[0006] 2. All the water in the water tank needs to be heated to boiling, which consumes a lot of energy.
[0007] 3. During each production shift, the water tank needs to be added with water at least 4 times. After adding water, it is necessary to wait until the heating temperature is reached before production can begin. This not only increases labor intensity and restricts production efficiency, but also increases energy consumption.
[0008] 4. If the top cover is not installed, water vapor will dissipate too quickly, and water and energy consumption will increase significantly. If the top cover is installed, the condensed water droplets on the top cover will drip down onto the flat filter paper, causing the filter paper to be locally too wet and making folding more difficult.
[0009] 5. Water rust or scale is easy to form on the electric heating tube, which is easy to be damaged. The heating tube needs to be replaced regularly. The later maintenance workload is large and the maintenance cost is high. Utility Model Content
[0010] The purpose of the utility model is to provide an automatic filter paper humidifying device, which does not require heating water to boiling and does not require heating preparation 30 minutes in advance, and can produce a good humidifying effect on flat filter paper.
[0011] To achieve the above-mentioned purpose, the utility model provides an automatic filter paper humidifying device including a frame, a humidifying box provided on the frame, the humidifying box having a top cover, and paper feed holes and paper outlet holes correspondingly provided on the opposite side walls of the humidifying box below the top cover, an air distribution cylinder is provided in the humidifying box below the paper feed hole and the paper outlet hole, and a plurality of air distribution holes are evenly provided on the air distribution cylinder; a steam pipe is connected to one end of the air distribution cylinder, the steam pipe extends out of the humidifying box and is connected to a steam generator, and the steam generator is arranged on the ground on one side of the frame.
[0012] The top cover is arranged in an inclined shape with the middle portion being higher and the two sides being lower.
[0013] The utility model has the following advantages:
[0014] The utility model no longer requires water to be heated to a boil, thus significantly reducing energy consumption. The steam generator can generate steam within 1 minute. In the past, the heating operation had to be turned on 30 minutes before the start of the shift. Now, it only needs to be turned on 1 minute before the start of the shift, which does not delay the start of the shift, reduces labor consumption, and improves work efficiency. The steam generator can be directly connected to the water source, eliminating the need to add water to the water tank between shifts. This saves time waiting for the water to boil after adding water, reduces labor intensity, and improves work efficiency. Since there is no electric heating tube, there is no problem of rust or scale easily forming on the electric heating tube.
[0015] The top cover is higher in the middle and lower on both sides. This structure prevents the water droplets attached to the top cover (formed after steam condenses) from falling vertically. Instead, they will slide down to both sides along the top cover under the action of gravity, so that the water droplets will eventually gather downward along the side walls, greatly reducing the amount of water dripping onto the flat filter paper passing through the humidification box, and avoiding excessive humidity in the filter paper, which increases the difficulty of folding.

[0018] Figure 3 It is a three-dimensional structural diagram of the utility model. DETAILED DESCRIPTION
[0019] like Figures 1 to 3As shown, an automatic filter paper humidifying device of the present invention includes a frame 1, a humidifying box 2 is provided on the frame 1, the humidifying box 2 has a top cover 3, and a paper feed hole 4 and a paper outlet hole 5 are correspondingly opened on the opposite side walls of the humidifying box 2 below the top cover 3 (the paper feed hole 4 and the paper outlet hole 5 can interchange the functions of paper feed and paper outlet according to actual needs), an air distribution cylinder 6 is provided in the humidifying box 2 below the paper feed hole 4 and the paper outlet hole 5, and a plurality of air distribution holes are evenly provided on the air distribution cylinder 6; the through holes arranged on the side walls of the cylindrical structure are conventional structures, and the air distribution holes are not shown in the figure.
[0020] One end of the air distribution cylinder 6 is connected to a steam pipe 7 , which extends out of the humidification box 2 and is connected to a steam generator 8 , which is arranged on the ground on one side of the frame 1 .
[0021] The present invention eliminates the need to heat water to a boil, significantly reducing energy consumption. The steam generator 8 can generate steam within 1 minute. Previously, the heating operation needed to be turned on 30 minutes before the start of a shift. Now, the steam generator 8 only needs to be turned on 1 minute before the start of a shift, which does not delay the start of the shift, reducing labor consumption and improving work efficiency. The steam generator 8 can be directly connected to a water source, eliminating the need to add water to the water tank between shifts. This saves time waiting for the water to boil after adding water, reduces labor intensity, and improves work efficiency. Since there is no electric heating tube, there is no problem of rust or scale easily forming on the electric heating tube.
[0022] The top cover 3 is arranged in an inclined shape, with the center higher and the sides lower. This structure prevents water droplets (formed by condensation of steam) attached to the top cover 3 from falling vertically. Instead, they slide down the top cover 3 to the sides under the action of gravity, and eventually gather downward along the side walls. This significantly reduces the amount of water dripping onto the flat filter paper passing through the humidification box 2, and prevents the filter paper from becoming too wet, which increases the difficulty of folding.
[0023] During operation, the paper outlet hole 5 faces the corrugating machine of the subsequent process. The steam generator 8 is turned on one minute in advance before the start of the shift. The flat filter paper of the previous process enters the humidifying box 2 through the paper inlet hole 4, and is humidified by contact with steam in the humidifying box 2. By adjusting the steam production speed of the steam generator 8, the degree to which the flat filter paper is humidified can be adjusted. The humidified flat filter paper passes through the humidifying box 2 through the paper outlet hole 5 and is supplied to the corrugating machine, which folds the humidified flat filter paper into folded filter paper. With the utility model, it is only necessary to turn on the steam generator 8 one minute in advance, and there is no need to boil water or add water during the production process. Compared with the prior art, it not only reduces energy consumption but also increases production efficiency by more than 10%. Since the interference of water dripping from the top cover 3 is solved, the filter paper is humidified evenly and fully, which improves the quality of the corrugation and the quality of the folded filter paper product.
[0024] The above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents. Any modification or partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
