Description

Technical Field

[0001] The present invention provides an exhaust gas treatment device, which relates to the field of exhaust gas treatment equipment and technology, and particularly relates to an exhaust gas collection and treatment device for hot pressing and laminating calcium sulfate floors. Background Art

[0002] Calcium sulfate floors have excellent properties such as high strength, water resistance, moisture resistance, fire resistance, and anti-static properties, and are suitable for environments such as laboratories and electronic factories. They are composed of a bottom plate, a core board, reinforcing materials, and edge wrapping materials. Usually, there is also a decorative laminate on the surface of the calcium sulfate floor, which is adhered to the surface of the substrate through an adhesive.

[0003] The temperature for hot pressing and laminating is 120 - 180 °C, and a pressure of 5 - 15 MPa is applied to complete the lamination. During this process, the melting of the adhesive will generate formaldehyde gas and volatile organic gases. In addition, the heating of the calcium sulfate substrate will generate water vapor. In addition, there may also be gases such as sulfur dioxide and hydrogen sulfide. If these gases are allowed to disperse, they will affect the working environment, but existing hot pressing and laminating treatment equipment does not have relevant exhaust gas treatment structures.

[0004] In view of this, those skilled in the art have proposed an exhaust gas collection and treatment device for hot pressing and laminating calcium sulfate floors, which can not only avoid the harmful gases from affecting the working environment, but also be more conducive to the hot pressing and laminating operation of calcium sulfate floors. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides an exhaust gas collection and treatment device for hot pressing and laminating calcium sulfate floors, which relates to an automatic treatment tank structure. After putting the board in, the adhesive is melted by heating with an electric heating plate, and hot pressing and laminating are carried out through a pressure roller. The generated exhaust gas is input into a multi-stage scrubbing pool through an air pump for absorption. An automatic conveying structure is provided inside the treatment tank to realize the automatic control of the hot pressing temperature and time of the board, and ensure the processing quality.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: An exhaust gas collection and treatment device for hot pressing and laminating calcium sulfate floors, including a treatment tank, an electric heating plate, and a pressure roller. A closed treatment tank structure is designed for hot pressing and laminating the board with the end cover left. An electric heating plate is provided inside the treatment tank to provide a high-temperature environment, and a pressure effect on the board is provided through the pressure roller to ensure the laminating effect.

[0007] However, a single heating environment only has the function of reducing energy consumption. It is not easy to control the hot pressing and laminating time during use. If the heating time is too long, it is easy to cause the adhesive to denature and affect the adhesive effect. Therefore, those skilled in the art continue to improve the treatment tank.

[0008] A rotating shaft is provided inside the processing box. The rotating shaft is driven to rotate by an external power mechanism, and the hot pressing time is controlled by the periodic control of the rotating shaft.

[0009] Clamping plates are provided on the side surface of the rotating shaft, and the plates are placed through the clamping plates to prevent the plates from slipping when the rotating shaft rotates.

[0010] An access window is provided on the side surface of the processing box corresponding to the clamping plate. The plates are accessed through the access window to ensure the relatively heat-insulated environment of the processing box and reduce energy consumption.

[0011] A scrubbing pool is provided on the side surface of the processing box. The gas generated during the working process is input into the scrubbing pool through an air pump for multi-stage absorption. The remaining unabsorbed gas after absorption is input into the processing box again and ignited as fuel.

[0012] A conveying pipe is provided on the side surface of the scrubbing pool. The conveying pipe includes all pipelines for gas conveying. On the one hand, it ensures the gas conveying, and on the other hand, it is convenient for gas metering, thereby monitoring the gas absorption effect.

[0013] Preferably, a sliding rail is fixed inside the processing box. Rollers are provided on the side surface of the electric heating plate corresponding to the sliding rail, and the electric heating plate is slidably arranged inside the sliding rail through the rollers.

[0014] The length of the sliding rail will not hinder the rotation of the plate, and it can guide the advancement of the electric heating plate. When the plate rotates with the rotating shaft, it can drive the electric heating plate to advance to avoid the rotation range, preventing the rotation and conveying of the plate from being affected. The rotation and conveying of the plate with the rotating shaft can control the heating time and obtain a better hot pressing and laminating effect.

[0015] Preferably, fixing rods are symmetrically fixed on the outer side of the sliding rail. One end of the fixing rod away from the sliding rail is hinged with a first hinge rod, and one end of the first hinge rod away from the rotating shaft is hinged with the electric heating plate.

[0016] When the plate rotates and is processed inside the processing box with the rotating shaft, as the plate approaches the electric heating plate, the plate first contacts the first hinge rod and applies a thrust force to the first hinge rod, causing the first hinge rod hinged through the fixing rod to deflect at an angle. Subsequently, the electric heating plate advances outward as the plate approaches, and the electric heating plate resets after the plate passes through the position of the electric heating plate to continue heating the next plate.

[0017] Preferably, a convex block is fixedly connected to the side surface of the sliding rail. A second hinge rod is slidably clamped to the side surface of the sliding rail near one end of the rotating shaft through the convex block. The second hinge rod is hinged with the first hinge rod. When the first hinge rod is subjected to a pressure force, the hinged part rotates, enabling the first hinge rod to adapt to the position of the plate and change at an angle.

[0018] A chute is formed through the side face of the second hinge rod corresponding to the convex block. The second hinge rod is slidably clamped with the convex block through the chute, and the second hinge rod is slidably clamped with the slide rail through the convex block. The pressure received by the first hinge rod acts on the second hinge rod, causing the second hinge rod to slide relatively according to the convex block, so that while the first hinge rod deflects, its position changes along with the sheet material.

[0019] Preferably, a spring is sleeved on the side face of the end of the second hinge rod. The spring provides a restoring force for the second hinge rod. After the pressure on the first hinge rod is removed, the elastic force of the spring pushes the second hinge rod to reset, and then the first hinge rod and the electric heating plate are reset together, so as to realize continuous heating of subsequent sheet materials.

[0020] A third hinge rod is rotatably arranged on the side face of the slide rail. The two ends of the third hinge rod are respectively slidably clamped with the electric heating plate and the first hinge rod. By connecting the movements of the electric heating plate and the first hinge rod through the third hinge rod, the associated driving effect of the first hinge rod on the electric heating plate is realized.

[0021] Preferably, a fixing block is fixed on the inner wall of the processing box. The access window is slidably clamped with the processing box through the fixing block, and the fixing block ensures a good fixing effect between the access window and the processing box.

[0022] A baffle is fixed on the inner wall of the access window corresponding to the fixing block. A pin is inserted into the side face of the baffle corresponding to the clamping plate. When the sheet material moves around with the rotating shaft and returns to the position near the access window, the pin contacts and presses against the side face of the sheet material in advance, and the sheet material is taken out conveniently as the access window is pulled out.

[0023] Preferably, a partition plate is inclined and fixed inside the scrubbing tank. The scrubbing tank is divided into multiple separate scrubbing areas by the partition plate. The partition plate is fixed at a certain angle with the horizontal plane, so that the scrubbing tank is divided into multiple spaces with inclined tops. In the space with this structure, it is convenient to collect gas and has a good scrubbing effect.

[0024] In addition, by dividing the scrubbing tank into multiple independent areas by the partition plate, scrubbing operations with multiple different absorbent liquids can be carried out according to the composition of the waste gas, ensuring the treatment effect on the waste gas.

[0025] An air diffuser pipe is fixed at the end of the conveying pipe passing through the scrubbing tank. The gas sent into the scrubbing tank through the conveying pipe is aerated through the air diffuser pipe to ensure a better absorption effect of the absorbent liquid.

[0026] Preferably, a liquid guide pipe is arranged through the side face of the scrubbing tank, and the absorbent liquid is replaced through the liquid guide pipe.

[0027] The conveying pipe is fixed with an observation buckle, and an observation fan blade is rotatably arranged inside the observation buckle. The observation buckle is in an oblate shape and is a tubular structure made of a transparent material. When gas is unidirectionally conveyed along the conveying pipe, it drives the observation fan blade to rotate in one direction, and the amount of conveyed gas is observed through the rotation speed.

[0028] Preferably, a dial is hinged inside the observation buckle, and a counting dial is fixed to the side wall of the observation buckle corresponding to the dial. As the observation fan blade rotates, the dial deflects a corresponding number of times against the elastic force, and each deflection drives the counting dial to record the quantity. Thus, the volume of gas passing through the conveying pipe at each stage can be conveniently observed through the counting dial, and the absorption effect can be judged according to the volume change of the gas.

[0029] A reset rod is inserted into the side of the counting dial, and the reading of the counting dial is reset by pressing the reset rod.

[0030] The present invention discloses a waste gas collection and treatment device for hot press laminating of calcium sulfate floors, and its beneficial effects are as follows:

[0031] 1. For the waste gas collection and treatment device for hot press laminating of calcium sulfate floors, a hot press laminating device for calcium sulfate floors that is heated in a treatment tank is designed. Hot pressing in a closed space is beneficial for energy conservation and emission reduction, and it is convenient to absorb the gas generated during the process. The clamping plate for fixing the plate rotates periodically along with the rotating shaft, and the hot pressing treatment time of the plate is controlled through the rotation period, avoiding the influence of heating time error on the laminating effect. The generated gas is introduced into a scrubbing tank for multi-stage absorption, and absorption is carried out according to the waste gas components to ensure better treatment. The remaining gas is ignited in the treatment tank again to avoid the diffusion of harmful gases into the working environment and facilitate the hot press laminating work.

[0032] 2. For the waste gas collection and treatment device for hot press laminating of calcium sulfate floors, the scrubbing tank is divided into multiple independent intervals by a partition inclined to the horizontal plane, and different components of absorption liquids are used in each interval for gas absorption, so that the waste gas can be more accurately scrubbed and absorbed. After the waste gas is input into the scrubbing tank through the conveying pipe, it is aerated through the aeration pipe, and then output again through the top formed by the partition. Combined with the conveying pipe and the observation buckle arranged on the side of the scrubbing tank, the waste gas absorption effect can be judged and the absorption liquid can be replaced accordingly. Finally, the unabsorbed organic gas is introduced into the treatment tank for combustion treatment to reduce the influence of waste gas diffusion on the working environment.

[0033] 3. For the waste gas collection and treatment device for hot press laminating of calcium sulfate floors, the clamping plate for fixing the plate is periodically driven by the rotating shaft, and thus the heating time of the plate is controlled by controlling the rotation period of the rotating shaft. Furthermore, the adhesion effect of the plate is ensured by controlling the heat treatment time, avoiding the decomposition of the adhesive due to long-term heating and affecting the adhesive effect.

[0034] 4. For the waste gas collection and treatment equipment for hot press laminating of calcium sulfate floor, the electric heating plate is slidably arranged in the treatment box through a slide rail, and a first hinge rod is correspondingly arranged to press against the plate and drive the electric heating plate to move forward accordingly. As the rotating shaft rotates, the plate positioned by the clamping plate contacts and applies a pressure force to the first hinge rod. The first hinge rod pushes the second hinge rod to slide relative to the slide rail. While storing elastic potential energy, the first hinge rod presses against the side of the plate and moves, and at the same time drives the associated electric heating plate to move away from the plate side. After the plate crosses the setting surface of the electric heating plate, the spring drives the first hinge rod to reset, and the electric heating plate also resets accordingly, waiting to heat the subsequent plates.

[0043] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be described clearly and completely. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0044] An embodiment of the present invention discloses an exhaust gas collection and treatment device for hot pressing and laminating calcium sulfate floors;

[0045] According to the attached Figure 1 and the attached Figure 2 As shown, it includes a treatment box 1, an electric heating plate 2 and a pressing roller 3. A closed treatment box 1 structure is designed for hot pressing and laminating end cover plates. An electric heating plate 2 is arranged inside the treatment box 1 to provide a high-temperature environment, and a pressing roller 3 is used to apply pressure to the plates to ensure the laminating effect.

[0046] However, a single heating environment only serves to reduce energy consumption. During use, it is not easy to control the hot pressing and laminating time. If the heating time is too long, it is easy to cause the adhesive to denature and affect the adhesive effect. Therefore, those skilled in the art continue to improve the treatment box 1.

[0047] A rotating shaft 4 is arranged inside the treatment box 1. The rotating shaft 4 is driven to rotate by an external power mechanism, and the hot pressing time is controlled through the periodic control of the rotating shaft 4.

[0048] Clamping plates 5 are arranged on the side of the rotating shaft 4, and the plates are placed through the clamping plates 5 to prevent the plates from slipping when the rotating shaft 4 rotates.

[0049] An access window 6 is arranged on the side of the treatment box 1 corresponding to the clamping plates 5. The plates are accessed through the access window 6 to ensure the relatively heat-insulated environment of the treatment box 1 and reduce energy consumption.

[0050] A scrubbing pool 7 is arranged on the side of the treatment box 1. The gas generated during the working process is input into the scrubbing pool 7 through an air pump for multi-stage absorption, and the remaining gas that cannot be absorbed after absorption is input into the treatment box 1 again and ignited as fuel.

[0051] A conveying pipe 8 is arranged on the side of the scrubbing pool 7. The conveying pipe 8 includes all pipelines for gas conveying. On the one hand, it ensures the gas conveying, and on the other hand, it facilitates the metering of the gas, thereby monitoring the gas absorption effect.

[0052] The structure of the processing box 1 is as compact as possible and is not limited to the illustrated shape. A power mechanism is arranged outside the processing box 1 to drive the rotating shaft 4 to rotate periodically. After the plate is coated with adhesive, it is placed into the clamping plate 5 through the access window 6. With the rotation of the rotating shaft 4, heat treatment is carried out in the processing box 1. As the plate approaches the electric heating plate 2, the adhesive melts, and under the pressing action of the pressing roller 3, the plate is compacted and adhered to the surface layer. The gas generated during this period is input into the scrubbing pool 7 by the air pump for multi-stage absorption. The remaining gas after absorption is input into the processing box 1 again for combustion to avoid diffusion and affect the working environment.

[0053] According to the attachment Figure 3 As shown, a slide rail 9 is fixed inside the processing box 1, and rollers 10 are arranged on the side of the electric heating plate 2 corresponding to the slide rail 9. The electric heating plate 2 is slidably arranged inside the slide rail 9 through the rollers 10.

[0054] The length of the slide rail 9 will not hinder the rotation of the rotating plate, and can guide the advancement of the electric heating plate 2. When the plate rotates with the rotating shaft 4, it can drive the electric heating plate 2 to advance to avoid the rotation range, so as not to affect the rotation and transportation of the plate. The rotation and transportation of the plate with the rotating shaft 4 can control the heating time to obtain a better hot pressing and laminating effect.

[0055] Fixed rods 11 are symmetrically fixed on the outside of the slide rail 9. One end of the fixed rod 11 away from the slide rail 9 is hinged with a first hinge rod 12, and one end of the first hinge rod 12 away from the rotating shaft 4 is hinged with the electric heating plate 2.

[0056] When the plate rotates and is processed in the processing box 1 with the rotating shaft 4, as the plate approaches the electric heating plate 2, the plate first contacts the first hinge rod 12 and applies a thrust force to the first hinge rod 12, causing the first hinge rod 12 hinged through the fixed rod 11 to deflect at an angle. Then, as the plate approaches, the electric heating plate 2 advances outward. After the plate passes through the position of the electric heating plate 2, the electric heating plate 2 resets to continue heating the next plate.

[0057] A convex block 13 is fixedly connected to the side of the slide rail 9. One side of the slide rail 9 near the rotating shaft 4 is slidably clamped with a second hinge rod 14 through the convex block 13. The second hinge rod 14 is hinged with the first hinge rod 12. When the first hinge rod 12 is under pressure, the hinged part rotates, enabling the first hinge rod 12 to adapt to the position of the plate and change at an angle.

[0058] A chute is penetrated through the side of the second hinge rod 14 corresponding to the convex block 13. The second hinge rod 14 is slidably clamped with the convex block 13 through the chute. The second hinge rod 14 is slidably clamped with the slide rail 9 through the convex block 13. The pressure received by the first hinge rod 12 acts on the second hinge rod 14, causing the second hinge rod 14 to slide relatively according to the convex block 13, thereby realizing that while the first hinge rod 12 deflects, it also changes its position along with the plate.

[0059] A spring 15 is sleeved on the side of the end of the second hinge rod 14. The spring 15 provides the restoring force for the second hinge rod 14. After the first hinge rod 12 loses the pressure, the elastic force of the spring 15 pushes the second hinge rod 14 to reset. Consequently, the first hinge rod 12 and the heating plate 2 are reset together, thus realizing continuous heating and use of subsequent plates.

[0060] A third hinge rod 16 is rotatably arranged on the side of the slide rail 9. The two ends of the third hinge rod 16 are respectively in sliding and clamping connection with the heating plate 2 and the first hinge rod 12. By associating the movements of the heating plate 2 and the first hinge rod 12 through the third hinge rod 16, the associated driving effect of the first hinge rod 12 on the heating plate 2 is realized.

[0061] According to the attached Figure 4 As shown in the figure, a fixing block 17 is fixed on the inner wall of the processing box 1. The access window 6 is in sliding and clamping connection with the processing box 1 through the fixing block 17. The fixing block 17 ensures a good fixing effect between the access window 6 and the processing box 1.

[0062] A baffle 18 is fixed on the inner wall of the access window 6 corresponding to the fixing block 17. A plug pin 19 is inserted on the side of the baffle 18 corresponding to the clamping plate 5. When the plate moves around with the rotating shaft 4 and returns to the position near the access window 6, the plug pin 19 pre - contacts and presses against the side of the plate. As the access window 6 is pulled out, the plate is taken out conveniently.

[0063] According to the attached Figure 5 and the attached Figure 6 As shown in the figure, a partition plate 20 is fixed obliquely on the inner side of the scrubbing pool 7. The scrubbing pool 7 is divided into multiple separate scrubbing intervals by the partition plate 20. The partition plate 20 is fixed at a certain angle with the horizontal plane, so that the scrubbing pool 7 is divided into multiple spaces with inclined tops. In the space of this structure, it is convenient to collect gas and has a good scrubbing effect.

[0064] In addition, by dividing the scrubbing pool 7 into multiple independent intervals through the partition plate 20, scrubbing operations with multiple different absorbent liquids can be carried out according to the composition of the waste gas, ensuring the treatment effect on the waste gas.

[0065] An aeration pipe 21 is fixed at the end of the conveying pipe 8 passing through the scrubbing pool 7. The gas sent into the scrubbing pool 7 through the conveying pipe 8 is aerated through the aeration pipe 21 to ensure a better absorption effect of the absorbent liquid.

[0066] A liquid guide pipe 22 is arranged through the side of the scrubbing pool 7. The absorbent liquid is replaced through the liquid guide pipe 22.

[0067] An observation buckle 23 is fixed on the conveying pipe 8. An observation fan blade 24 is rotatably arranged inside the observation buckle 23. The observation buckle 23 is a flat - round - shaped and transparent - material tubular structure. When the gas is transported unidirectionally along the conveying pipe 8, it drives the observation fan blade 24 to rotate in one direction, and the amount of the transported gas is observed through the rotation speed.

[0068] A dial 25 is hinged inside the observation buckle 23, and a counting dial 26 is fixed to the side wall of the observation buckle 23 corresponding to the dial 25. As the observation fan blade 24 rotates, the dial 25 deflects a corresponding number of times against the elastic force, and each deflection drives the counting dial 26 to record the quantity. Thus, it is convenient to observe the volume of gas passing through the delivery pipe 8 at each stage through the counting dial 26, and the absorption effect can be judged according to the change in the volume of the gas.

[0069] A reset rod 27 is inserted on the side of the counting dial 26, and the reading of the counting dial 26 is reset by pressing the reset rod 27.

[0070] In this calcium sulfate floor hot-pressing and laminating waste gas collection and treatment device, a calcium sulfate floor hot-pressing and laminating device for heating is designed in the treatment tank 1. Hot-pressing in a closed space is conducive to energy conservation and emission reduction, and is convenient for absorbing the gas generated during the process. The clamping plate 5 for fixing the board rotates periodically with the rotating shaft 4, and the hot-pressing treatment time of the board is controlled by the rotation period, avoiding the influence of heating time error on the laminating effect. The generated gas is introduced into the scrubbing tank 7 for multi-stage absorption, and the absorption is carried out according to the waste gas components to ensure better treatment. The remaining gas is ignited in the treatment tank 1 again to avoid the diffusion of harmful gases into the working environment and facilitate the hot-pressing and laminating work.

[0071] Furthermore, the scrubbing tank 7 is divided into multiple independent intervals by a partition plate 20 inclined to the horizontal plane, and different components of absorption liquids are used in each interval for gas absorption, so that the waste gas can be scrubbed and absorbed more accurately. After the waste gas is input into the scrubbing tank 7 through the delivery pipe 8, aeration is carried out through the aeration pipe 21, and then it is output again through the top formed by the partition plate 20. Combining with the delivery pipe 8 and the observation buckle 23 arranged on the side of the scrubbing tank 7, the waste gas absorption effect can be judged and the absorption liquid can be replaced accordingly. Finally, the unabsorbed organic gas is introduced into the treatment tank 1 for combustion treatment to reduce the impact of waste gas diffusion on the working environment.

[0072] Even further, the clamping plate 5 for fixing the board is periodically driven by the rotating shaft 4, and thus the heating time of the board is controlled by controlling the rotation period of the rotating shaft 4. Furthermore, the adhesion effect of the board is ensured by controlling the heat treatment time, avoiding the decomposition of the adhesive due to long-term heating and affecting the adhesive effect.

[0073] Further, the electric heating plate 2 is slidably arranged in the processing box 1 through a slide rail 9, and a first hinge rod 12 for pressing against the plate and driving the electric heating plate 2 to advance accordingly is provided. As the rotating shaft 4 rotates, the plate positioned by the clamping plate 5 contacts the first hinge rod 12 and applies a pressure thereto. The first hinge rod 12 pushes the second hinge rod 14 to slide relative to the slide rail 9. While storing elastic potential energy, the first hinge rod 12 presses against the side of the plate and moves, and at the same time drives the associated electric heating plate 2 to advance away from the plate side. After the plate passes over the setting surface of the electric heating plate 2, the spring 15 drives the first hinge rod 12 to reset, and the electric heating plate 2 also resets accordingly, waiting to heat the subsequent plates.

[0074] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and all these changes and improvements fall within the scope of the present invention claimed.
