Description

Technical Field

[0001] The invention proposes an exhaust gas treatment device, relates to the exhaust gas treatment equipment and technical field, and specifically relates to an exhaust gas collection and treatment device for hot-pressed veneer of calcium sulfate floor. Background Art

[0002] Calcium sulfate flooring has excellent properties such as high strength, waterproof, moisture-proof, fire-proof and anti-static. It is suitable for laboratories, electronic factories and other environments. It is composed of a base plate, a core, reinforcement materials and edging materials. Usually, there is a decorative veneer layer on the surface of the calcium sulfate floor, which is adhered to the surface of the substrate with adhesives.

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

[0004] In view of this, technical personnel in this field have proposed a waste gas collection and treatment device for hot-pressing veneering of calcium sulfate floors, which can not only avoid harmful gases from affecting the working environment, but also be more conducive to the hot-pressing veneering operation of calcium sulfate floors. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a waste gas collection and treatment device for hot-pressing veneering of calcium sulfate floors, which relates to an automatic processing box structure. After the board is placed in, the adhesive is heated and melted by an electric heating plate, and hot-pressing veneering is carried out by a pressing roller. The generated waste gas is input into a multi-stage washing pool through an air pump for absorption. An automatic conveying structure is arranged on the inside of the processing box to realize automatic control of the hot-pressing temperature and time of the board to ensure the processing quality.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a calcium sulfate floor hot-press veneering waste gas collection and treatment device, including a treatment box, an electric heating plate and a pressure roller, the closed treatment box structure is designed to carry out the hot-press veneering operation of the end cover board material, the electric heating plate is arranged on the inner side of the treatment box to provide a high temperature environment, and the pressure effect on the board is provided by the pressure roller to ensure the veneering effect.

[0007] However, a single heating environment only has the effect of reducing energy consumption. It is not easy to control the hot pressing cladding time during use. Too long heating time can easily cause the adhesive to denature and affect the bonding effect. Therefore, technical personnel in this field continue to improve the processing box.

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

[0009] A clamping plate is arranged on the side of the rotating shaft, and the plate is placed through the clamping plate to prevent the plate from slipping when the rotating shaft rotates.

[0010] The side of the processing box is provided with a storage and access window corresponding to the clamping plate, and the plate is stored and accessed through the storage and access window, so as to ensure the relative heat preservation environment of the processing box and reduce energy consumption.

[0011] A gas washing pool is arranged on the side of the processing box. The gas generated during the working process is input into the gas washing pool through an air pump for multi-stage absorption. After absorption, the remaining gas that cannot be absorbed is input into the processing box again as fuel to be ignited.

[0012] A delivery pipe is provided on the side of the gas washing pool. The delivery pipe includes all pipelines for gas delivery. On the one hand, it ensures the delivery of gas, and on the other hand, it facilitates the measurement of gas and further monitors the gas absorption effect.

[0013] Preferably, a slide rail is fixed on the inner side of the processing box, rollers are provided on the side of the electric heating plate corresponding to the slide rail, and the electric heating plate is slidably arranged on the inner side of the slide rail via the rollers.

[0014] The length of the slide rail will not hinder the rotating plate, and can guide the advancement of the electric heating plate. When the plate rotates with the rotating shaft, the electric heating plate can be driven to advance to avoid the rotation range and avoid affecting the rotation and transportation of the plate. The heating time of the plate can be controlled as the rotating shaft is transported, thereby obtaining a better hot pressing veneer effect.

[0015] Preferably, a fixing rod is symmetrically fixed to the outer side of the slide rail, an end of the fixing rod away from the slide rail is hinged to a first hinge rod, and an end of the first hinge rod away from the rotating shaft is hinged to the electric heating plate.

[0016] When the plate is rotated in the processing box along with the rotating shaft, as the plate approaches the electric heating plate, the plate contacts the first hinge rod in advance, and a thrust is applied to the first hinge rod, causing the first hinge rod hinged by the fixed rod to deflect at an angle, and then the electric heating plate moves toward the outside as the plate approaches. After the plate passes the position of the electric heating plate, the electric heating plate resets and continues to heat the next plate.

[0017] Preferably, a protrusion is fixedly connected to the side of the slide rail, and the side of the slide rail close to one end of the rotating shaft is slidably clamped with a second hinge through the protrusion. The second hinge is hinged to the first hinge. When the first hinge is subjected to pressure, the hinged part rotates, so that the first hinge adapts to the angle change of the position of the plate.

[0018] A sliding groove is provided on the side of the second hinge rod corresponding to the protrusion, and the second hinge rod is slidably engaged with the protrusion through the sliding groove. The second hinge rod is slidably engaged with the slide rail through the protrusion. The pressure exerted on the first hinge rod acts on the second hinge rod, causing the second hinge rod to slide relatively according to the protrusion, thereby achieving the deflection of the first hinge rod and the change of position along with the plate.

[0019] Preferably, a spring is provided on the side sleeve of the end of the second hinge rod, and the spring provides a reset force for the second hinge rod. After the first hinge rod loses the pressure effect, 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, thereby realizing continuous heating of subsequent plates.

[0020] The side of the slide rail is rotatably provided with a third hinge rod, and the two ends of the third hinge rod are respectively slidably engaged with the electric heating plate and the first hinge rod. The movement of the electric heating plate and the first hinge rod is associated with the third hinge rod, so that the associated driving effect of the first hinge rod on the electric heating plate is realized.

[0021] Preferably, a fixing block is fixed to the inner wall of the processing box, and the access window is slidably engaged with the processing box via the fixing block, so that the access window is well fixed to the processing box via the fixing block.

[0022] A baffle is fixed to the fixed block corresponding to the inner wall of the access window, and a latch is provided on the side of the baffle corresponding to the clamping plate. When the plate moves one circle along with the rotating shaft and returns to the vicinity of the access window, the latch pre-contacts and presses against the side of the plate, and the plate is pulled out as the access window is pulled, making it easy to take out.

[0023] Preferably, a partition is fixed at an angle on the inner side of the gas washing pool, and the gas washing pool is divided into a plurality of separate gas washing areas by the partition. The partition is fixed at a certain angle to the horizontal plane, so that the gas washing pool is divided into a plurality of spaces with inclined tops. The space of this structure is convenient for collecting gas and has a better gas washing effect.

[0024] In addition, the scrubbing pool is divided into a plurality of independent sections by the partition, and scrubbing operations with a variety of different absorption liquids can be performed according to the waste gas composition, thereby ensuring the treatment effect of the waste gas.

[0025] An aeration pipe is fixed to the end of the delivery pipe that passes through the washing tank. The gas delivered into the washing tank through the delivery pipe is aerated through the aeration pipe to ensure a better absorption effect of the absorption liquid.

[0026] Preferably, a liquid guide tube is provided through the side of the gas washing pool, and the absorption liquid is replaced through the liquid guide tube.

[0027] The delivery pipe is fixed with an observation buckle, and an observation fan blade is rotatably arranged inside the observation buckle. The observation buckle is an oblate tubular structure made of transparent material. When the gas is transported unidirectionally along the delivery pipe, the observation fan blade is driven to rotate in one direction, and the amount of gas transported is observed by the rotation speed.

[0028] Preferably, a paddle is hingedly provided on the inner side of the observation buckle, and a counting dial is fixed to the side wall of the observation buckle corresponding to the paddle. As the observation fan blade rotates, the paddle overcomes the elastic force and deflects a corresponding number of times. Each deflection drives the counting dial to record the number, so that the volume of gas passing through the delivery pipe at each stage can be conveniently observed through the counting dial, and the absorption effect can be judged according to the change in the volume of the gas.

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

[0030] The present invention discloses a calcium sulfate floor hot-pressing veneer waste gas collection and treatment device, which has the following beneficial effects: 1. The waste gas collection and treatment equipment for hot-pressing veneering of calcium sulfate floor is designed to heat the calcium sulfate floor hot-pressing veneering device in a treatment box. Hot pressing in a closed space is conducive to energy conservation and emission reduction, and is convenient for absorbing the gas generated in the process. The clamping plate used to fix the board rotates periodically with the rotating shaft. The hot-pressing treatment time of the board is controlled by the rotation cycle to avoid the heating time error affecting the veneering effect. The generated gas is passed into the gas washing pool for multi-stage absorption, and the waste gas components are absorbed to ensure better treatment. The remaining gas is once again passed into the treatment box and ignited to avoid the spread of harmful gases to the working environment and facilitate the hot-pressing veneering work.

[0031] 2. The waste gas collection and treatment equipment for hot-pressed veneering of calcium sulfate flooring divides the washing pool into multiple independent areas through partitions inclined on the horizontal plane. Each area uses absorption liquid with different components for gas absorption, which can wash and absorb the waste gas more accurately. The waste gas is input into the washing pool through the delivery pipe and aerated through the aeration pipe, and then output again through the top formed by the partition. Combined with the delivery pipe and observation buckle set on the side of the washing pool, the waste gas absorption effect can be judged and the absorption liquid can be replaced accordingly. Finally, the organic gas that cannot be absorbed is passed into the treatment box for combustion treatment, thereby reducing the impact of waste gas diffusion on the working environment.

[0032] 3. The waste gas collection and treatment equipment for hot-pressed veneering of calcium sulfate floor uses a clamping plate for fixing the board to be periodically driven by a rotating shaft, thereby controlling the heating time of the board by controlling the rotation cycle of the rotating shaft, and thereby ensuring the adhesion of the board by controlling the heat treatment time, thereby avoiding the long-term heating and decomposition of the adhesive that affects the adhesion effect.

[0033] 4. The waste gas collection and treatment equipment for hot-pressed veneering of calcium sulfate flooring, the electric heating plate is slidably set in the treatment box through a slide rail, and a first hinge rod is correspondingly set to press against the plate and drive the electric heating plate to move forward. With the rotation of the rotating shaft, the plate positioned by the clamping plate contacts and exerts pressure on the first hinge rod, and the first hinge rod pushes the second hinge rod to slide relative to the slide rail. While accumulating elastic potential energy, the first hinge rod presses against the side of the plate and moves, and at the same time drives the electric heating plate driven in association with it to move toward the side away from the plate. After the plate passes 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 plate.

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] The embodiment of the present invention discloses a waste gas collection and treatment device for hot-pressing veneer of calcium sulfate floor; According to the attached Figure 1 and attached Figure 2 As shown, it includes a processing box 1, an electric heating plate 2 and a pressure roller 3. The closed processing box 1 structure is designed to carry out hot pressing and veneer operations on the end cover plate material. The electric heating plate 2 is arranged on the inner side of the processing box 1 to provide a high temperature environment, and the pressure effect on the plate is provided by the pressure roller 3 to ensure the veneer effect.

[0039] However, a single heating environment only has the effect of reducing energy consumption. It is not easy to control the hot pressing cladding time during use. Too long heating time can easily cause the adhesive to denature and affect the bonding effect. Therefore, technical personnel in this field continue to improve the processing box 1.

[0040] A rotating shaft 4 is arranged inside the processing box 1 . The rotating shaft 4 is driven to rotate by an external power mechanism, and the hot pressing time is controlled by periodic control of the rotating shaft 4 .

[0041] A clamping plate 5 is provided on the side of the rotating shaft 4, and the plate is placed by the clamping plate 5 to prevent the plate from sliding when the rotating shaft 4 rotates.

[0042] A storage and access window 6 is provided on the side of the processing box 1 corresponding to the clamping plate 5, and the plate is stored and accessed through the storage and access window 6, ensuring a relatively heat-insulating environment of the processing box 1 to reduce energy consumption.

[0043] A gas washing pool 7 is arranged on the side of the processing box 1. The gas generated during the working process is input into the gas washing pool 7 through an air pump for multi-stage absorption. After the absorption, the remaining gas that cannot be absorbed is input into the processing box 1 again to be ignited as fuel.

[0044] A delivery pipe 8 is provided on the side of the gas washing pool 7. The delivery pipe 8 includes all pipelines for gas delivery. On the one hand, it ensures the delivery of the gas, and on the other hand, it facilitates the measurement of the gas and further monitors the gas absorption effect.

[0045] The structure of the processing box 1 is as compact as possible and is not limited to the shape shown in the figure. 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 in the clamping plate 5 through the access window 6. As the rotating shaft 4 rotates, it is heated in the processing box 1. As the plate approaches the electric heating plate 2, the adhesive melts. Under the pressing action of the pressing roller 3, the plate and the surface layer are compacted and adhered. The gas generated during this period is input into the washing tank 7 through an air pump for multi-stage absorption. After absorption, the remaining gas is input into the processing box 1 again for combustion to avoid diffusion and affect the working environment.

[0046] According to the attached Figure 3 As shown, a slide rail 9 is fixed on the inner side of the processing box 1 , and a roller 10 is provided on the side of the electric heating plate 2 corresponding to the slide rail 9 , and the electric heating plate 2 is slidably arranged on the inner side of the slide rail 9 via the roller 10 .

[0047] The length of the slide rail 9 will not hinder the rotating plate, and can guide the advancement of the electric heating plate 2. When the plate rotates with the rotating shaft 4, the electric heating plate 2 can be driven to advance to avoid the rotation range and avoid affecting the rotation and transportation of the plate. The heating time can be controlled as the plate is transported with the rotating shaft 4 to obtain a better hot pressing veneer effect.

[0048] A fixing rod 11 is symmetrically fixed to the outer side of the slide rail 9 , and a first hinge rod 12 is hinged to one end of the fixing rod 11 away from the slide rail 9 . An end of the first hinge rod 12 away from the rotating shaft 4 is hinged to the electric heating plate 2 .

[0049] When the plate is rotated along with the rotating shaft 4 in the processing box 1, as the plate approaches the electric heating plate 2, the plate contacts the first hinge 12 in advance, and a thrust is applied to the first hinge 12, causing the first hinge 12 hinged by the fixed rod 11 to deflect at an angle, and then the electric heating plate 2 moves toward the outside as the plate approaches. After the plate passes the position of the electric heating plate 2, the electric heating plate 2 resets and continues to heat the next plate.

[0050] A protrusion 13 is fixedly connected to the side of the slide rail 9, and a second hinge 14 is slidably connected to the side of the slide rail 9 close to the rotating shaft 4 through the protrusion 13. The second hinge 14 is hinged to the first hinge 12. When the first hinge 12 is subjected to pressure, the hinged part rotates, so that the first hinge 12 changes its angle to adapt to the position of the plate.

[0051] A sliding groove is provided on the side of the second hinge rod 14 corresponding to the protrusion 13, and the second hinge rod 14 is slidably engaged with the protrusion 13 through the sliding groove. The second hinge rod 14 is slidably engaged with the slide rail 9 through the protrusion 13. The pressure exerted on the first hinge rod 12 acts on the second hinge rod 14, causing the second hinge rod 14 to slide relatively according to the protrusion 13, thereby achieving the deflection of the first hinge rod 12 and the change of position along with the plate.

[0052] A spring 15 is provided on the side of the end of the second hinge rod 14, and the spring 15 provides a reset force for the second hinge rod 14. After the first hinge rod 12 loses the pressure effect, the elastic force of the spring 15 pushes the second hinge rod 14 to reset, and then the first hinge rod 12 and the electric heating plate 2 are reset together, thereby realizing continuous heating of subsequent plates.

[0053] A third hinge rod 16 is rotatably arranged on the side of the slide rail 9, and both ends of the third hinge rod 16 are respectively slidably engaged with the electric heating plate 2 and the first hinge rod 12. The movement of the electric heating plate 2 and the first hinge rod 12 is associated by the third hinge rod 16, so that the associated driving effect of the first hinge rod 12 on the electric heating plate 2 is realized.

[0054] According to the attached Figure 4 As shown, a fixing block 17 is fixed to the inner wall of the processing box 1 , and the access window 6 is slidably engaged with the processing box 1 through the fixing block 17 , and the access window 6 is well fixed to the processing box 1 through the fixing block 17 .

[0055] A baffle 18 is fixed to the inner wall of the access window 6 corresponding to the fixed block 17, and a latch 19 is provided on the side of the baffle 18 corresponding to the clamping plate 5. When the plate moves one circle along with the rotating shaft 4 and returns to the vicinity of the access window 6, the latch 19 pre-contacts and presses against the side of the plate, and the plate is pulled out as the access window 6 is pulled out, making it easy to take out.

[0056] According to the attached Figure 5 and attached Figure 6 As shown, a partition 20 is fixed at an angle on the inner side of the washing pool 7, and the washing pool 7 is divided into a plurality of separate washing areas by the partition 20. The partition 20 is fixed at a certain angle to the horizontal plane, so that the washing pool 7 is divided into a plurality of spaces with inclined tops. The space of this structure is convenient for collecting gas and has a better washing effect.

[0057] In addition, the scrubbing pool 7 is divided into a plurality of independent sections by the partition plate 20, and scrubbing operations with a variety of different absorption liquids can be performed according to the waste gas composition to ensure the treatment effect of the waste gas.

[0058] An aeration pipe 21 is fixed to the end of the delivery pipe 8 that passes through the washing tank 7. The gas delivered into the washing tank 7 through the delivery pipe 8 is aerated through the aeration pipe 21 to ensure a better absorption effect of the absorption liquid.

[0059] A liquid guide pipe 22 is provided through the side of the gas washing pool 7, and the absorption liquid is replaced through the liquid guide pipe 22.

[0060] An observation buckle 23 is fixed to the delivery pipe 8, and an observation fan blade 24 is rotatably arranged inside the observation buckle 23. The observation buckle 23 is an oblate tubular structure made of transparent material. When the gas is transported unidirectionally along the delivery pipe 8, the observation fan blade 24 is driven to rotate in one direction, and the amount of gas transported is observed by the rotation speed.

[0061] A paddle 25 is hingedly provided on the inner side of the observation buckle 23, and a counting dial 26 is fixed to the side wall of the observation buckle 23 corresponding to the paddle 25. As the observation fan blade 24 rotates, the paddle 25 overcomes the elastic force and deflects a corresponding number of times. Each deflection drives the counting dial 26 to record the quantity, and then the counting dial 26 can be used to conveniently observe the volume of gas passing through the delivery pipe 8 at each stage, and the absorption effect can be judged according to the change in the volume of the gas.

[0062] A reset rod 27 is inserted and provided on the side of the counting dial 26 , and the indication of the counting dial 26 is reset by pressing the reset rod 27 .

[0063] The waste gas collection and treatment equipment for hot-pressing veneering of calcium sulfate floor is designed as a hot-pressing veneering device for calcium sulfate floor which is heated in a treatment box 1. Hot pressing in a closed space is beneficial to energy conservation and emission reduction and is convenient for absorbing the gas generated in the process. The clamping plate 5 for fixing the board rotates periodically with the rotating shaft 4. The hot-pressing treatment time of the board is controlled through the rotation cycle to avoid the heating time error affecting the veneering effect. The generated gas is passed into the washing pool 7 for multi-stage absorption, and the waste gas components are absorbed to ensure better treatment. The remaining gas is once again passed into the treatment box 1 and ignited to avoid the diffusion of harmful gases into the working environment and facilitate the hot-pressing veneering work.

[0064] Furthermore, the scrubbing tank 7 is divided into a plurality of independent sections by a partition 20 inclined to the horizontal plane. Each section uses an absorption liquid with different components for gas absorption, so that the waste gas can be scrubbed and absorbed more accurately. The waste gas is input into the scrubbing tank 7 through the delivery pipe 8 and aerated through the aeration pipe 21, and then output again through the top formed by the partition 20. Combined 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 organic gas that cannot be absorbed is passed into the treatment box 1 for combustion treatment, thereby reducing the impact of waste gas diffusion on the working environment.

[0065] Furthermore, the clamping plate 5 for fixing the plate is periodically driven by the rotating shaft 4, and the heating time of the plate is controlled by controlling the rotation period of the rotating shaft 4, and the adhesion effect of the plate is ensured by controlling the heat treatment time, avoiding the long-term heating and decomposition of the adhesive affecting the adhesion effect.

[0066] Furthermore, the electric heating plate 2 is slidably set in the processing box 1 through the slide rail 9, and a first hinge rod 12 is correspondingly set to press against the plate and drive the electric heating plate 2 to advance. As the rotating shaft 4 rotates, the plate positioned by the clamping plate 5 contacts and exerts pressure on the first hinge rod 12, and the first hinge rod 12 pushes the second hinge rod 14 to slide relative to the slide rail 9. While accumulating elastic potential energy, the first hinge rod 12 presses against the side of the plate and moves, and at the same time drives the electric heating plate 2 driven in association with it to advance to the side away from the plate. After the plate passes 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 for the subsequent plate to be heated.
