Description

Technical Field

[0001] This utility model belongs to the technical field of hot pressing equipment, and specifically relates to a hot pressing device with a waste gas treatment structure. Background Technology

[0002] The hot-pressing process of corrugated cardboard generates volatile organic compounds (VOCs) and other waste gases. If these waste gases are not effectively treated, they may pollute the environment, affect air quality, and harm the health of operators. Furthermore, the accumulation of untreated waste gases during production can lead to increased odors and harmful gas concentrations in the workshop, potentially disrupting normal production.

[0003] Conventional solutions include adding waste gas treatment equipment, such as activated carbon adsorption units, catalytic oxidizers, or other waste gas purification systems, to the hot press to reduce volatile organic compound (VOC) emissions and meet environmental standards. However, implementing these methods often incurs additional economic burdens, including increased equipment purchase and maintenance costs, which can impact profits, especially in small businesses. Furthermore, adding waste gas treatment equipment may occupy more space and extend production line operating procedures, thus affecting production efficiency. Moreover, some waste gas treatment technologies may generate secondary pollution during the purification process, posing new environmental challenges. Therefore, we aim to design a hot press with a novel structure to address this issue. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 3The present invention provides a technical solution: a hot pressing device with a waste gas treatment structure, comprising: a hot pressing device body 100 and a waste gas treatment component 200, wherein the hot pressing device body 100 is equipped with a waste gas treatment component 200 for centralized treatment of waste gas generated by corrugated semi-hot pressing.

[0025] The exhaust gas treatment assembly 200 includes a dust collection hood 210, a treatment box 220, and a connecting pipe 230. The upper middle of the dust collection hood 210 is fixedly connected to the lower end of the connecting pipe 230 used for transmitting exhaust gas. The dust collection hood 210 is connected to the treatment box 220 used for adsorption treatment of exhaust gas through the connecting pipe 230.

[0026] Please see Figures 1 to 3 The hot pressing device body 100 includes a slide table 110 and a frame 120. Two guide seats are respectively provided on the left and right sides of the lower end of the frame 120. An electric cylinder for driving the slide table 110 to move back and forth at the bottom of the frame 120 is installed in the middle of the bottom in the front-back direction.

[0027] A guide rod is fixed on the left and right sides of the bottom of the slide table 110 to guide the slide table 110. The slide table 110 is slidably installed on the bottom of the frame 120 via an electric cylinder and the guide rod.

[0028] A hydraulic cylinder 140 is installed in the middle of the upper end of the frame 120. A roller pressing module 130 for hot pressing corrugated cardboard is movably installed on the top of the frame 120 through the hydraulic cylinder 140. The roller pressing module 130 is located on the upper side of the slide table 110.

[0029] As the first embodiment of this utility model, by installing a waste gas treatment component 200 on the upper side of the hot press device body 100, in actual use, when corrugated cardboard is placed on the hot press device body 100 and hot-pressed by the roller pressing module 130 of the slide table 110, the waste gas generated will rise due to the high temperature. At this time, the exhaust fan in the air duct 222 on the treatment box 220 starts, which causes a negative pressure to be generated inside the treatment box 220, the connecting pipe 230 and the two dust collection hoods 210. As a result, the air on the front and rear sides of the upper end of the frame 120 enters the dust collection hood 210 under the influence of the negative pressure, and enters the treatment box through the connecting pipe 230. In the inner cavity 225 at the bottom of the box 220, the air containing exhaust gas passes through the perforated plate 223 and the adsorbent packing 224 under the action of the exhaust fan inside the air duct 222. When the exhaust gas passes through the multi-layer adsorbent packing 224, the adsorbent packing 224 with specific treatment performance can adsorb and treat the harmful substances in the exhaust gas (the internal adsorbent packing 224 can be replaced periodically), thereby achieving the purpose of treating the hot-pressed exhaust gas. The entire structure is attached to the hot-pressing device body 100, does not occupy too much workshop production space, and is very simple and low-cost to improve the existing hot-pressing equipment in the workshop.

[0030] Please see Figures 2 to 3 The dust collection hood 210 includes an expansion hood 214 and a dust collection pipe 215. The lower end of the dust collection pipe 215 is welded with an expansion hood 214 for increasing the airflow rate. The lower end of the expansion hood 214 is open, and the width of the cross section of the expansion hood 214 gradually increases from top to bottom in the left-right direction. In actual use, the two dust collection hoods 210 are respectively placed on the upper front side and the upper rear side of the frame 120, which can better collect the exhaust gas generated by the hot pressing device body 100 when hot pressing the corrugated cardboard, and prevent it from escaping in large quantities and polluting the environment.

[0031] An inclined plate 213 is welded at a 30-degree angle to the inside of the left and right sides of the dust collection pipe 215 to reduce the internal volume of the dust collection pipe 215. The two inclined plates 213 are arranged in a mirror symmetrical manner.

[0032] A partition 212 is welded to the lower end of the dust collection pipe 215. Multiple ventilation holes 216 are formed on the upper surface of the partition 212 from left to right downwards. A net 211 for intercepting larger debris is magnetically connected to the lower surface of the partition 212.

[0033] The upper end of the treatment box 220 is provided with a duct 222 for installing an exhaust fan. The middle of the treatment box 220 is provided with multiple perforated plates 223 for placing packing material. Adsorbent packing material 224 for adsorbing and treating waste gas is placed between the multiple perforated plates 223. The bottom of the treatment box 220 is provided with an inner cavity 225. In actual use, the adsorbent packing material 224 can be selected according to the specific composition of the waste gas generated by actual hot pressing to ensure that the generated waste gas can be effectively purified.

[0034] The lower end of the connecting pipe 230 extends downward through the upper end of the frame 120 and communicates with the interior of the upper end of the dust collection pipe 215. The upper end of the connecting pipe 230 is connected to the inner cavity 225 at the bottom of the processing box 220.

[0035] As a second embodiment of this utility model, based on the first embodiment described above, the arrangement of the partition 212, the inclined plate 213, and the screen 211 ensures, in actual use, that the partition 212, through its waist hole 216, can form a uniform suction space on the lower side of the dust collection pipe 215. Combined with the inclined plates 213 on both sides, it can make the negative pressure at various points on the lower side of the dust collection pipe 215 less different, which can prevent the generated exhaust gas from escaping and is conducive to improving the concentration effect of exhaust gas. The arrangement of the screen 211 can ensure that the negative pressure will not suck in large impurities, causing the exhaust gas treatment component 200 to become blocked.

[0036] The above description is only a preferred embodiment of the present utility model and is 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 should be included within the protection scope of the present utility model.
