Description

Technical Field

[0001] The utility model relates to the technical field of paper product printing production equipment, in particular to a drying device applied to paper product printing. Background Art

[0002] The paper product printing process is to print patterns or texts on paper products through a printing press. After printing, the paper products are relatively wet, and it is difficult to fix the printed patterns and texts, and it is also easy to cause tearing. At present, after the paper products are printed, they are usually dried by sunning. This drying method not only has low efficiency and slow speed, but also cannot guarantee the drying quality. After sunning, the paper printed products need to be recycled, which is time-consuming, laborious and has a high labor cost.

[0003] Therefore, in the existing printing production process, a drying device is usually used to dry the wet paper products. However, the printing ink on the paper products will volatilize organic waste gas during the heating and drying process, and the existing drying devices do not have the function of waste gas treatment. This will not only pollute the air, but also endanger the health of the operators in the processing factory. Summary of the Invention

[0025] The following will elaborate on the technical solutions of the present utility model in conjunction with the accompanying drawings and embodiments.

[0026] Please refer to Figures 1 to 3 As shown, the embodiments of the present application provide a drying device applied to paper product printing, which is characterized in that it includes:

[0027] A drying box 1, installed on the printing paper product conveyor belt 100;

[0028] A drying hood 2, installed inside the drying box 1, with an electric heating plate 3 at its lower end for heating and drying the printing paper products conveyed on the printing paper product conveyor belt 100, and an air intake grille structure 20 opened at its upper end;

[0029] An exhaust gas collection mechanism 4, arranged on the air intake grille structure 20, for collecting the organic exhaust gas generated during the heating and drying of the printing paper products;

[0030] An exhaust gas purification mechanism 5, arranged at the upper end of the drying box 1 and communicated with the exhaust gas collection mechanism 4, for adsorbing and purifying the organic exhaust gas;

[0031] An exhaust mechanism 6, arranged at the upper end of the exhaust gas collection mechanism 4 and communicated with the exhaust gas purification mechanism 5, for discharging the exhaust gas that has completed the purification treatment.

[0032] During processing, the un-dried paper products are moved to directly below the drying hood 2 through the printed paper conveyor belt 100. Then, the electric heating plate 3 heats up to dry the paper products. The organic waste gas generated during the drying process is collected by the waste gas collection mechanism 4, and then the organic waste gas is purified by the waste gas purification mechanism 5. Finally, the treated waste gas is discharged through the exhaust mechanism 6, realizing one-stop processing of drying, waste gas collection, and waste gas treatment, greatly reducing air pollution and protecting the health of operators at the same time.

[0033] Furthermore, the waste gas collection mechanism 4 includes a first exhaust fan 41 provided on the intake grille structure 20, and a first drive motor 42 for driving the first exhaust fan 41 to rotate. A gas collecting box 43 that can cover the intake grille structure 20 is also provided at the upper end of the drying box 1, and the gas collecting box 43 is communicated with the waste gas purification mechanism 5.

[0034] In this embodiment, the working principle of the waste gas collection mechanism 4 is as follows:

[0035] The first drive motor 42 is started, driving the first exhaust fan 41 to rotate, thereby generating an upward airflow from bottom to top above the printed paper products, and then driving the organic waste gas to move upward and be collected into the gas collecting box 43, and then sent to the waste gas purification mechanism 5, which is practical and convenient.

[0036] Furthermore, the waste gas purification mechanism 5 includes a purification barrel 51 provided at the upper end of the drying box 1, activated carbon particles 52 (not shown in the figure) filled in the purification barrel 51, and an air outlet pipe 53 and an air inlet pipe 54 provided at the upper and lower ends of the side wall of the purification barrel 51. The air outlet pipe 53 is communicated with the exhaust mechanism 6, and the air inlet pipe 54 is communicated with the waste gas collection mechanism 4.

[0038] In this embodiment, the working principle of the waste gas purification mechanism 5 is as follows:

[0039] The organic waste gas enters the purification barrel 51 from the air inlet pipe 54. Then, through the upward diversion of the exhaust mechanism 6 and the upward rise of the hot air of the organic waste gas itself, the organic waste gas flows from the bottom of the purification barrel 51 to the top of the purification barrel 51, thereby passing through the activated carbon particles in the purification barrel 51. Furthermore, the activated carbon particles can fully react with the organic waste gas, adsorbing the organic particles in the waste gas, achieving the effect of purifying the organic waste gas. Finally, the purified waste gas enters the exhaust mechanism 6 from the air outlet pipe 53, which is practical and convenient.

The exhaust box 61 is communicated with the waste gas purification mechanism 5.

[0041] In this embodiment, the working principle of the exhaust mechanism 6 is as follows:

[0042] The second drive motor 63 is started to drive the second exhaust fan 62 to rotate, so as to generate an upward airflow in the exhaust box 61, and then drive the organic waste gas to move upward and be discharged from the exhaust grille structure 610, which is practical and convenient.

[0043] Specifically, in this embodiment, through the cooperation of the first exhaust fan 41 and the second exhaust fan 62, an airflow direction from the drying hood 2 → the air collecting box 43 → the intake pipe 54 → the purification barrel 51 → the outlet pipe 53 → the exhaust box 61 → outside the device is formed in the device, which is practical and convenient.

[0044] Further, a protective cover 7 capable of covering the waste gas purification mechanism 5 and the exhaust mechanism 6 is further provided on the drying box 1.

[0045] Specifically, a first clearance groove 70 allowing the exhaust grille structure 610 to be exposed is further provided at the upper end of the protective cover 7.

[0046] Protected by the protective cover 7, the interference from the outside to the waste gas purification mechanism 5 and the exhaust mechanism 6 is reduced, and the service life is improved.

[0047] Further, a plurality of air-permeable long holes 30 are arranged on the electric heating plate 3. It can enable the organic waste gas to pass through smoothly, which is practical and convenient.

[0048] Further, a second clearance groove 10 allowing the intake grille structure 20 to be exposed is further provided at the upper end of the drying box 1.

[0049] To sum up, during the processing of this application embodiment, the un-dried paper products are moved to directly below the drying hood 2 through the printed paper product conveyor belt 100, and then the electric heating plate 3 is heated to dry the paper products. The organic waste gas generated during the drying process is collected by the waste gas collection mechanism 4, then the organic waste gas is purified by the waste gas purification mechanism 5, and finally the treated waste gas is discharged through the exhaust mechanism 6, realizing one-stop processing of drying, waste gas collection, and waste gas treatment, greatly reducing the occurrence of air pollution and protecting the physical health of the operators at the same time.
