Description

A waste gas treatment device for glue drying Technical Field

[0001] This utility model relates to the field of glue drying technology, specifically to a waste gas treatment device for glue drying. Background Technology

[0002] In the paper processing industry, the drying process after applying adhesive is an indispensable step. However, current drying equipment mostly uses a single heat source to dry the paper, and its design focuses primarily on the curing efficiency of the adhesive, lacking effective collection and treatment mechanisms for the waste gases (such as volatile organic compounds or odorous gases) emitted during the drying process. These waste gases are often directly emitted into the air, not only polluting the environment but also potentially posing a threat to the health of operators.

[0003] Furthermore, existing equipment typically only supports drying single-sided coated paper. For double-sided coated paper, the drying capacity is limited, and the emissions are further aggravated by double-sided heating. Additionally, maintenance or replacement of exhaust gas treatment components (if any) is complex, often requiring disassembly of the main equipment, increasing downtime and maintenance costs. Summary of the Invention

[0004] This utility model addresses the technical problems existing in the prior art by providing a waste gas treatment device for glue drying. This solves the problem that existing equipment usually only supports drying single-sided glued paper. For double-sided glued paper, the drying capacity is limited, and the amount of waste gas emitted is further aggravated by double-sided heating, lacking an effective collection and treatment mechanism.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a waste gas treatment device for glue drying, comprising:

[0006] frame;

[0007] A conveying device, which is mounted on a frame, is used to transport paper;

[0008] Furnace body shell, which is located above the conveying device and mounted on the frame;

[0009] A heating assembly, comprising a first heating tube and a second heating tube, wherein the first heating tube and the second heating tube are parallel vertically and disposed within the outer shell of the furnace body;

[0010] The feed inlet is located on one side of the furnace shell.

[0011] A furnace hood, which is movable outside the feed inlet of the furnace body shell;

[0012] A filter assembly, wherein the filter assembly is disposed inside the furnace hood;

[0013] An adsorption assembly, which is located on one side of the filter assembly and disposed inside the furnace hood;

[0014] A support frame is located between the first heating tube and the second heating tube and is mounted on the furnace hood.

[0015] The beneficial effects of this utility model are:

[0016] 1) This device has a first heating tube and a second heating tube arranged vertically parallel inside the furnace shell. For paper with single-sided adhesive coating, it can be conveyed into the furnace shell via a conveyor, and the adhesive-coated surface of the paper is dried using the heating tube (such as the second heating tube) near the conveyor. For paper with double-sided adhesive coating, the paper is placed on a support frame inside the furnace hood via a feed inlet located on one side of the furnace shell and a movable furnace hood. At this time, the support frame is located between the first and second heating tubes. By closing the furnace hood, the paper is placed in the clamping area between the two heating tubes. The first and second heating tubes heat the upper and lower surfaces of the paper respectively, thereby achieving simultaneous drying of the double-sided adhesive. This not only improves drying efficiency but also expands the application range of the device and meets diverse production needs.

[0017] 2) In addition, the integrated filter and adsorption components inside the furnace cover form a complete waste gas treatment structure. During the glue drying process, volatile organic compounds or odorous gases are actively and efficiently drawn in by the adsorption components, and then purified by the filter components, ultimately achieving clean emission of waste gas. In summary, the reasonable layout of the filter and adsorption components ensures the high efficiency of waste gas treatment and avoids the accumulation of waste gas inside the furnace. Moreover, when it is necessary to replace or clean the filter components, maintenance can be completed simply by pulling out the furnace cover, without disassembling the entire device, which greatly reduces downtime and improves production continuity.

[0018] Based on the above technical solution, the present invention can be further improved as follows.

[0019] Furthermore, the adsorption assembly includes an adsorption tube, a negative pressure fan, and an adsorption port. The adsorption port is located on the outside of the furnace hood, one end of the adsorption tube is connected to one side of the adsorption port of the furnace hood, and the negative pressure fan is located on the other side of the adsorption port and is installed inside the furnace hood.

[0020] The beneficial effect of adopting the above-mentioned further solution is that the waste gas inside the furnace shell is actively adsorbed by the negative pressure fan and discharged through the adsorption pipe.

[0021] Furthermore, the filter assembly includes an activated carbon layer.

[0022] Furthermore, the support frame includes a first vertical rod, a second vertical rod, and multiple horizontal rods, with one end of the first vertical rod and one end of the second vertical rod respectively fixed to both sides of the furnace hood.

[0023] Furthermore, multiple crossbars are fixed in a linear array between the first vertical bar and the second vertical bar.

[0024] Furthermore, each of the crossbars has multiple protrusions on its exterior.

[0025] The beneficial effect of adopting the above-mentioned further solution is that when the paper is placed on the support frame, the support point is no longer the entire surface of the crossbar, but rather multiple protrusions that directly contact the paper. This effectively reduces the contact area between the paper and the crossbar surface. Since the glue is applied to the paper surface, large-area contact between the paper and the crossbar may cause the glue to adhere to or transfer to the crossbar surface, resulting in glue loss. However, the introduction of protrusions restricts the contact point to a smaller area of ​​the protrusions, greatly reducing the contact area between the glue and the support frame surface. This effectively avoids the situation where glue adheres to the support frame, significantly reducing glue loss and helping to keep the support frame clean, thus reducing subsequent maintenance work caused by glue residue.

[0026] Furthermore, a handle is fixedly connected to the outer side of the furnace hood. Attached Figure Description

[0033] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0034] In the paper processing industry, the drying process after applying adhesive is an indispensable step. However, current drying equipment mostly uses a single heat source to dry the paper, and its design focuses primarily on the curing efficiency of the adhesive, lacking effective collection and treatment mechanisms for the waste gases (such as volatile organic compounds or odorous gases) emitted during the drying process. These waste gases are often directly emitted into the air, not only polluting the environment but also potentially posing a threat to the health of operators.

[0035] Furthermore, existing equipment typically only supports drying single-sided glued paper. For double-sided glued paper, the drying capacity is limited, and the amount of exhaust gas emitted is further aggravated by double-sided heating. Meanwhile, the maintenance or replacement of exhaust gas treatment components (if any) is complex, often requiring disassembly of the main equipment, increasing downtime and maintenance costs. To address these issues, the inventor has proposed an exhaust gas treatment device for glue drying.

[0036] The present invention provides the following preferred embodiments.

[0037] As shown in Figures 1-4, a waste gas treatment device for glue drying includes:

[0038] Rack 10;

[0039] The conveying device (which uses a common industrial conveyor belt for transport, and will not be described in detail here) is mounted on the frame 10 and is used to transport paper.

[0040] Furnace shell 20, the furnace shell 20 is located above the conveying device and is mounted on the frame 10;

[0041] Heating assembly 30 includes a first heating tube 301 and a second heating tube 302. The first heating tube 301 and the second heating tube 302 are parallel vertically and are disposed inside the furnace shell 20.

[0042] The feed inlet is located on one side of the furnace shell 20;

[0043] Furnace hood 40 is movable outside the feed inlet of furnace shell 20;

[0044] Filter assembly 50 is disposed inside furnace hood 40;

[0045] Adsorption component 60 is located on one side of filter component 50 and is disposed inside furnace hood 40;

[0046] Support frame 70 is located between the first heating tube 301 and the second heating tube 302 and is mounted on the furnace cover 40.

[0047] This device has a first heating tube 301 and a second heating tube 302 arranged vertically inside the furnace shell 20. For paper with single-sided adhesive coating, it can be conveyed into the furnace shell 20 by a conveying device 90, and the adhesive-coated surface of the paper is dried using a heating tube (such as the second heating tube 302) near the conveying device 90. For paper with double-sided adhesive coating, the paper is placed on a support frame 70 inside the furnace hood 40 through a feed inlet on one side of the furnace shell 20 and a movable furnace hood 40. At this time, the support frame 70 is located between the first heating tube 301 and the second heating tube 302. By closing the furnace hood 40, the paper is placed in the clamping area of ​​the two heating tubes. The first heating tube 301 and the second heating tube 302 heat the upper and lower surfaces of the paper respectively, thereby achieving simultaneous drying of the double-sided adhesive. This not only improves the drying efficiency but also expands the application range of the device and meets diverse production needs.

[0048] In addition, the filter assembly 50 and adsorption assembly 60 are integrated inside the furnace cover 40 to form a complete waste gas treatment structure. During the glue drying process, volatile organic compounds or odorous gases are actively and efficiently drawn in by the adsorption assembly 60, and then purified by the filter assembly 50, ultimately achieving clean emission of waste gas. In summary, the reasonable layout of the filter assembly 50 and adsorption assembly 60 ensures the high efficiency of waste gas treatment and avoids the accumulation of waste gas inside the furnace. Moreover, when it is necessary to replace or clean the filter assembly 50, maintenance can be completed simply by pulling out the furnace cover 40 without disassembling the entire device, which greatly reduces downtime and improves production continuity.

[0049] In this embodiment, as shown in Figures 1-4, the adsorption assembly 60 includes an adsorption tube 601, a negative pressure fan 602, and an adsorption port 603. The adsorption port 603 is located on the outside of the furnace hood 40. One end of the adsorption tube 601 is connected to one side of the adsorption port 603 of the furnace hood 40. The negative pressure fan 602 is located on the other side of the adsorption port 603 and is installed inside the furnace hood 40. The negative pressure fan 602 actively adsorbs the waste gas inside the furnace shell 20 and discharges the waste gas through the adsorption tube 601.

[0050] In this embodiment, as shown in Figures 1-4, the filter assembly 50 includes an activated carbon layer.

[0051] In this embodiment, as shown in Figures 1-4, the support frame 70 includes a first vertical rod 701, a second vertical rod 702, and a plurality of horizontal rods 703. One end of the first vertical rod 701 and the second vertical rod 702 are respectively fixed to both sides of the furnace cover 40, and the plurality of horizontal rods 703 are fixed in a linear array between the first vertical rod 701 and the second vertical rod 702.

[0052] In this embodiment, as shown in Figures 1-4, each crossbar 703 has multiple protrusions 704 on its exterior. When the paper is placed on the support frame 70, the support point is no longer the entire surface of the crossbar 703, but rather the multiple protrusions 704 directly contacting the paper. This effectively reduces the contact area between the paper and the surface of the crossbar 703. Since the adhesive is applied to the surface of the paper, a large contact area between the paper and the crossbar 703 may cause the adhesive to adhere to or transfer to the surface of the crossbar 703, resulting in adhesive loss. The introduction of the protrusions 704 restricts the contact point to a smaller area of ​​the protrusions 704, greatly reducing the contact area between the adhesive and the surface of the support frame 70. This effectively prevents the adhesive from adhering to the support frame 70, significantly reducing adhesive loss and helping to keep the support frame 70 clean, thus reducing subsequent maintenance work caused by adhesive residue.

[0053] In this embodiment, as shown in Figures 1-4, a handle 80 is fixedly connected to the outer side of the furnace cover 40.

[0054] The specific working process of this utility model is as follows:

[0055] (1) Drying of single-sided glue on paper

[0056] For paper coated with glue on one side, it can be conveyed to the furnace shell 20 by the conveying device 90, and the glued surface of the paper can be dried by the heating tube (such as the second heating tube 302) near the conveying device 90.

[0057] (2) Drying of double-sided adhesive on paper

[0058] For paper coated with adhesive on both sides, the paper is placed on the support frame 70 inside the furnace hood 40 through the feed port provided on one side of the furnace shell 20 and the furnace hood 40 that is movably connected. At this time, the support frame 70 is located between the first heating tube 301 and the second heating tube 302. By closing the furnace hood 40, the paper is placed in the clamping area of ​​the two heating tubes. The first heating tube 301 and the second heating tube 302 heat the upper and lower surfaces of the paper respectively, thereby achieving synchronous drying of the double-sided adhesive.

[0059] (3) Adsorption of waste gas

[0060] The negative pressure fan 602 actively adsorbs the waste gas generated after the glue is dried inside the furnace shell 20, so that the waste gas passes through the activated carbon layer, and the filtered waste gas is discharged through the adsorption tube 601.

[0061] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
