[0025] The adsorption plate 7 is made of charcoal material, and there are three adsorption plates 7, which are evenly distributed inside the drying box 6. By setting the adsorption plate 7, when the pulp molding is dried, the hot air is transported to the inside of the drying box 2, and the hot air can bake the pulp molding inside the drying box 2, so that the moisture inside the pulp molding evaporates by heat to form water vapor, and then is transported to the inside of the drying box 6 through the exhaust pipe 5, so that the adsorption plate 7 can adsorb and dry the water vapor, thereby achieving the water vapor drying treatment effect, thereby avoiding the problem of water vapor staying around the pulp molding for a long time and causing the humidity of the pulp molding to increase, thereby improving the drying speed of the pulp molding, that is, improving the drying efficiency of the dryer.

[0026] The conveying mechanism 9 includes an air pump 91, which is fixedly installed on the top of the support plate 1. The top of the air pump 91 is fixedly sleeved with an air duct 92, and one end of the air duct 92 is fixedly sleeved on the side of the drying box 2. By setting the conveying mechanism 9, when the water vapor drying process is carried out, the air pump 91 is started, so that the air pump 91 can absorb the airflow inside the drying box 6 through the air pipe 8, and then discharge it to the inside of the drying box 2 through the air duct 92, thereby achieving the hot air rotation effect, that is, improving the heat utilization efficiency.

[0027] The electric heating column 10 and the support plate 1 are perpendicular to each other, and there are several electric heating columns 10. By setting the electric heating column 10, when the pulp molding drying process is carried out, the electric heating column 10 is started so that the electric heating column 10 can heat the air flow inside the drying box 2, that is, the heating speed of the pulp molding is increased, thereby achieving the baking effect of the pulp molding.

[0028] The ventilation mechanism 12 includes a rotating motor 121, which is fixedly installed inside the ventilation hood 3, and a fan blade 122 is fixedly sleeved on the output shaft of the rotating motor 121; by setting the ventilation mechanism 12, when pulp molding and drying are carried out, the rotating motor 121 is started, so that the rotating motor 121 can drive the fan blade 122 to rotate rapidly, and at this time, the fan blade 122 can quickly inject the airflow outside the drying box 2 into the interior of the drying box 2, thereby increasing the flow speed of the airflow inside the drying box 2, that is, increasing the drying speed of the pulp molding.

[0029] The material of the filter cover 4 is synthetic fiber material, and the number of filter covers 4 is two; by setting the filter cover 4, when pulp molding and drying are carried out, the filter cover 4 can filter the airflow entering the drying box 2, so that the dust inside the airflow can be blocked by the filter cover 4 to the outside of the drying box 2, thereby avoiding the problem of dust entering the drying box 2 along with the airflow and causing the inside of the drying box 2 to be contaminated.

[0030] The closing mechanism 13 includes a closing door 131, which is movably sleeved on the front of the drying box 2, and a magnet block 132 is fixedly sleeved on the front of the drying box 2; by setting the closing mechanism 13, when pulp molding and drying are being carried out, the closing door 131 is rotated so that the magnet block 132 can absorb the closing door 131, and at this time the closing door 131 can be adsorbed and fixed on the front of the drying box 2, thereby achieving a closing effect of the drying box 2, and further facilitating the opening and closing of the drying box 2.

[0031] The moving mechanism 14 includes a support column 141, which is fixedly connected to the bottom of the support plate 1, and a sliding wheel 142 is installed at the bottom of the support column 141; by setting the moving mechanism 14, when the working position of the dryer is adjusted, the support plate 1 is pushed, so that the sliding wheel 142 can drive the support plate 1 to move horizontally through the support column 141, that is, drive the drying box 2 to move horizontally, thereby achieving the moving effect of the pulp molding dryer, and further bringing convenience to the working position adjustment of the pulp molding dryer.

[0032] The working principle of a high-efficiency and energy-saving pulp molding dryer provided by the utility model is as follows:

[0033] Step 1: First, when drying the pulp molding, hot air is transported to the interior of the drying box 2. At this time, the hot air can bake the pulp molding inside the drying box 2, so that the moisture inside the pulp molding is evaporated by heat to form water vapor, and then transported to the interior of the drying box 6 through the exhaust pipe 5, so that the adsorption plate 7 can adsorb and dry the water vapor, thereby achieving the water vapor drying effect, thereby avoiding the problem of water vapor staying around the pulp molding for a long time and causing the humidity of the pulp molding to increase, thereby improving the drying speed of the pulp molding, that is, improving the drying efficiency of the dryer. When the water vapor drying process is carried out, the air pump 91 is started, so that the air pump 91 can adsorb the moisture inside the drying box 6 through the air pipe 8. The airflow is absorbed and then discharged to the inside of the drying box 2 through the air duct 92, thereby achieving the effect of hot air rotation, that is, improving the use efficiency of heat. When the pulp molding is dried, the electric heating column 10 is started so that the electric heating column 10 can heat the airflow inside the drying box 2, that is, the heating speed of the pulp molding is increased, thereby achieving the baking effect of the pulp molding. When the pulp molding is dried, the rotating motor 121 is started so that the rotating motor 121 can drive the fan blades 122 to rotate rapidly. At this time, the fan blades 122 can quickly inject the airflow outside the drying box 2 into the drying box 2, thereby increasing the flow speed of the airflow inside the drying box 2, that is, increasing the drying speed of the pulp molding;

[0034] Step 2: When pulp molding is being dried, the filter cover 4 can filter the airflow entering the drying box 2, so that the dust in the airflow can be blocked by the filter cover 4 to the outside of the drying box 2, thereby avoiding the problem that dust enters the drying box 2 with the airflow and causes the inside of the drying box 2 to be polluted. When pulp molding is being dried, the closed door 131 is rotated so that the magnet block 132 can absorb the closed door 131. At this time, the closed door 131 can be adsorbed and fixed on the front of the drying box 2, thereby achieving the closing effect of the drying box 2, thereby facilitating the opening and closing of the drying box 2. When adjusting the working position of the dryer, the support plate 1 is pushed so that the sliding wheel 142 can drive the support plate 1 to move horizontally through the support column 141, that is, drive the drying box 2 to move horizontally, thereby achieving the moving effect of the pulp molding dryer, thereby facilitating the adjustment of the working position of the pulp molding dryer.

[0035] Compared with the related art, the high-efficiency and energy-saving pulp molding dryer provided by the utility model has the following beneficial effects:

[0036] By setting the adsorption plate 7, when the pulp molding is dried, the hot air is transported to the interior of the drying box 2, and the hot air can bake the pulp molding inside the drying box 2, so that the moisture inside the pulp molding evaporates due to the heat to form water vapor, and then is transported to the interior of the drying box 6 through the exhaust pipe 5, so that the adsorption plate 7 can adsorb and dry the water vapor, thereby achieving the water vapor drying treatment effect, and thus avoiding the problem of water vapor staying around the pulp molding for a long time and causing the humidity of the pulp molding to increase, thereby improving the drying speed of the pulp molding, that is, improving the drying efficiency of the dryer.
