Description

Technical Field

[0001] The utility model relates to the technical field of impregnated paper, in particular to a high-strength impregnated paper formaldehyde-removing device. Background Art

[0002] Formaldehyde is often widely used as an adhesive or additive in industrial production processes, which may lead to residual formaldehyde in the final products, posing a potential threat to the environment and human health. The main purpose of the device is to effectively remove or reduce the content of formaldehyde during the production process to ensure the environmental protection and safety of the products.

[0003] The existing patent CN219410344U discloses a production device for formaldehyde-removing and environment-friendly impregnated paper. This production device for formaldehyde-removing and environment-friendly impregnated paper includes a drying shell, and a conveying device for conveying the impregnated paper is inserted inside the drying shell, and a purification device for removing formaldehyde is arranged above the conveying device.

[0004] This patent solves the problems that directly spraying formaldehyde cleaning liquid is wasteful of water resources and the formaldehyde cleaning liquid is not fully utilized when removing formaldehyde from the impregnated paper. The above technical solution can make the overflow box full and then overflow from the four peripheral edges of the overflow box to form a water curtain and fall into the water collecting box, so as to realize the circulation of the formaldehyde cleaning liquid by setting a water pump and a water collecting box.

[0005] There is also a problem in the above solution that it is inconvenient to replace the purification device. Specifically, after the currently produced impregnated paper is coated with impregnating glue, it is generally pulled to the bottom of the suction fan by the rotation of the roller during drying, and the suction fan is started to suck formaldehyde and irritating gases into the exhaust pipe, and the formaldehyde is filtered and discharged through the filtering device in the exhaust pipe. Since the daily production volume of the impregnated paper is large, the staff needs to clean and replace the filtering device regularly. The filtering device is generally fixed in the exhaust pipe by bolts and requires certain tools for disassembly and installation. Such an operation is rather cumbersome, increasing the labor intensity of the staff. Therefore, the utility model proposes a high-strength impregnated paper formaldehyde-removing device. Summary of the Utility Model

By providing a fan, formaldehyde can be inhaled from the air inlet into the inner cavity of the purification box. By providing a filter screen, formaldehyde can be preliminarily filtered. The shape of the filter element is set to a spiral shape. Through the cooperation of the filter element and the second baffle, the air flow can flow spirally in the inner cavity of the purification box, increasing the contact time and contact area between the air flow and filter materials such as activated charcoal, and thus being able to better filter formaldehyde.

[0011] As a preferred embodiment, a connecting component is provided at the top of the purification box. The connecting component includes a connecting frame, a third chute is provided at the bottom of the connecting frame, one end of the second slider extends into the inner cavity of the third chute, and the second slider is movably connected to the inner cavity of the third chute.

[0012] The technical effect of adopting the above further scheme is that by providing a connecting frame, the purification box can be kept in a sealed state. The cooperation of the third chute and the second slider enables the purification box and the connecting frame to be quickly separated.

[0013] As a preferred embodiment, a second mounting block is provided at one end of the connecting frame, a third elastic sheet is provided in the inner cavity of the second mounting block, and a third slider is provided at the end of the third elastic sheet away from the second mounting block.

[0014] The technical effect of adopting the above further scheme is: by setting a second mounting block, the third spring sheet and the third slider can be supported, and the bottom of the third slider is set with a certain slope, which can drive the second mounting block to move upward when the connecting frame rises. When the second mounting block moves to a certain position, the third spring sheet will open the third slider, so that the position of the connecting frame can be fixed, thereby achieving the effect of facilitating the replacement of the purification box. After the replacement is completed, by pressing down the connecting frame, the third slider shrinks inward along the inner cavity of the groove, thereby achieving the effect of lowering the connecting frame.

[0015] Compared with the prior art, the advantages and positive effects of the utility model are:

[0016] A handle is provided on the side of the first baffle plate, and the position of the first baffle plate can be fixed by cooperating with the fixing block and the connecting block. When the internal live charcoal needs to be replaced, the switch handle can be pulled to drive the connecting block to move toward the inner cavity of the first mounting block. The connecting block moves toward the inner cavity of the first mounting block and separates from the inner cavity of the fixing block at the same time, thereby canceling the limitation of the first baffle plate. The first sliding groove and the first sliding block cooperate to limit the movement trajectory of the connecting block. The support plate is fixedly connected to the side of the first baffle plate. By pulling down the handle arranged on the side of the first baffle plate, the support plate and the purification box can be driven to flip outward, thereby achieving the effect of facilitating the replacement of the purification box.

One end of the first slider 28 extends into the inner cavity of the first chute 27. The first slider 28 is slidably connected with the inner cavity of the first chute 27. A handle is provided on the side of the first baffle 211. Through the cooperation of the fixing block 23 and the connecting block 24, the position of the first baffle 211 can be fixed, ensuring safety and stability in the normal use state. When it is necessary to replace the internal activated charcoal, by pulling the switch handle 25, the connecting block 24 can be driven to move into the inner cavity of the first mounting block 22. While the connecting block 24 moves into the inner cavity of the first mounting block 22, it disengages from the inner cavity of the fixing block 23, so that the limit on the first baffle 211 can be cancelled. Through the cooperation of the first chute 27 and the first slider 28, the movement track of the connecting block 24 can be limited. The support plate 38 is fixedly connected with the side of the first baffle 211. By pulling down the handle provided on the side of the first baffle 211, the support plate 38 and the purification box 33 can be driven to turn outward, so as to achieve the effect of facilitating the replacement of the purification box 33, greatly simplifying the operation process and improving the replacement efficiency.

[0031] Furthermore, as Figure 1 and Figure 2As shown: the inner cavity of the housing 21 is provided with a purification component 3, the purification component 3 includes an air inlet 31, a filter screen 32 is provided on the top of the air inlet 31, a support plate 38 is provided on the top of the filter screen 32, a purification box 33 is provided on the top of the support plate 38, a second slider 37 is provided on the top of the purification box 33, a filter element 34 is provided in the inner cavity of the purification box 33, a second baffle 35 is provided in the middle of the filter element 34, a fan 36 is provided on the top of the second baffle 35, a connecting component 5 is provided on the top of the purification box 33, the connecting component 5 includes a connecting frame 51, and the bottom of the connecting frame 51 is provided with a second slider 37. The third slide groove 55 is provided with one end of the second slider 37 extending to the inner cavity of the third slide groove 55, the second slider 37 is movably connected with the inner cavity of the third slide groove 55, a second mounting block 52 is provided at one end of the connecting frame 51, a third spring piece 53 is provided in the inner cavity of the second mounting block 52, a third slider 54 is provided at one end of the third spring piece 53 away from the second mounting block 52, the support plate 38 is fixedly connected to the side of the first baffle 211, the bottom of the purification box 33 is movably connected to the top of the support plate 38 by a buckle, so that it can be easily connected or separated from the top of the support plate 38, and the inner cavity of the purification box 33 is provided with charcoal and other filter materials, by setting a fan 36, formaldehyde can be sucked into the inner cavity of the purification box 33 from the air inlet 31, and the filter screen 32 is set to filter the formaldehyde preliminarily. The shape of the filter element 34 is set to a spiral shape, and the filter element 34 and the second baffle 35 cooperate to make the airflow spirally flow in the inner cavity of the purification box 33, thereby increasing the contact time and contact area between the airflow and the filter materials such as charcoal, so as to better filter the formaldehyde and avoid the problem of incomplete adsorption caused by too short a residence time. In order to facilitate the replacement of the purification box 33, the third chute 55 The design of the second slider 37 enables the purification box 33 and the connecting frame 51 to be quickly separated. In addition, the bottom of the third slider 54 is provided with a certain slope. When the connecting frame 51 rises, it can drive the second mounting block 52 to move upward. When the second mounting block 52 moves to a certain position, the third spring piece 53 opens the third slider 54, thereby fixing the position of the connecting frame 51 to prevent the connecting frame 51 from accidentally falling when the purification box 33 is replaced. After the replacement is completed, by pressing down the connecting frame 51, the third slider 54 shrinks inward along the inner cavity of the groove 210, so that the connecting frame 51 can be smoothly lowered.

[0032] When removing formaldehyde, it is difficult to judge whether the active charcoal is saturated due to the sealed state. Figure 4As shown in the figure: A detection component 4 is arranged at the top of the connection component 5. The detection component 4 includes a protective cover 41. A measuring pipeline 42 is arranged in the inner cavity of the protective cover 41. A movable block 43 is arranged in the inner cavity of the measuring pipeline 42. A second elastic sheet 45 is arranged at the top of the movable block 43. One end of the second elastic sheet 45 away from the movable block 43 is provided with a touch block 44. An alarm is arranged at the top of the touch block 44. When the activated charcoal is saturated in adsorption, the resistance increases, resulting in a significant increase in the pressure difference. The movable block 43 arranged in the inner cavity of the measuring pipeline 42 can move upward due to the increase in the pressure difference. When the movable block 43 moves upward, the second elastic sheet 45 is compressed. At the same time, the touch block 44 arranged at the top of the movable block 43 moves upward. When the pressure difference reaches a certain level, the touch block 44 touches the alarm, so that the staff can know that the activated charcoal inside is saturated in adsorption, and then can replace the activated charcoal inside in time to avoid the formaldehyde not being adsorbed and removed in time.

[0033] Working principle:

[0034] As Figures 1-5 shown:

[0035] During use: First, place the impregnated paper to be dried on the conveyor belt. Drying devices are provided on both sides of the conveyor belt. When drying the impregnated paper, formaldehyde is emitted. Start the fan 36, which can suck the formaldehyde upward. When the formaldehyde passes through the filter screen 32, it is preliminarily filtered. When entering the inner cavity of the purification box 33, through the cooperation of the filter element 34 and the baffle 35, the air flow can spiral in the inner cavity of the purification box 33, increasing the contact time and contact area between the air flow and filter materials such as activated charcoal, and thus being able to filter formaldehyde better. After the activated charcoal is saturated with adsorption, the resistance increases, resulting in a significant increase in the pressure difference. The movable block 43 arranged in the inner cavity of the measuring pipeline 42 can move upward due to the increase in the pressure difference, and then can drive the touch block 44 to move upward. An alarm is arranged on the top of the touch block 44. When the touch block 44 touches the alarm, the alarm sounds, so that it can be known that the internal activated charcoal is saturated with adsorption and needs to be replaced. The staff lifts the connecting frame 51 through the handle arranged on the top of the connecting frame 51. The connecting frame 51 is separated from the purification box 33. When the connecting frame 51 moves upward, it can drive the second mounting block 52 to move upward. When moving to a certain position, the third elastic piece 53 pushes the third slider 54 outward, so that it can be clamped in the inner cavity of the groove 210, and thus can achieve the effect of fixing the position of the connecting frame 51. Then pull the switch handle 25, so that the connecting block 24 can be separated from the inner cavity of the fixed block 23. Finally, pull downward the handle arranged on the side of the first baffle 211, so that the support plate 38 and the purification box 33 can be turned outward, and thus the activated charcoal and filter materials in the inner cavity of the purification box 33 can be directly replaced. After the replacement is completed, reset the support plate 38 and the purification box 33. Pull the switch handle 25 in the reverse direction, so that the connecting block 24 and the fixed block 23 can be clamped, and thus can achieve the effect of fixing their positions and preventing detachment. Press the connecting frame 51 downward, and the second mounting block 52 is reset along the inner cavity of the second chute 29. Then start the fan 36 to continue removing formaldehyde from the impregnated paper.

[0036] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
