Description

Technical Field

[0001] This invention relates to the field of paper product manufacturing technology, specifically to a wastewater and waste gas purification device for paper product manufacturing. Background Technology

[0002] Paper product manufacturing refers to the production activities that use paper and paperboard as raw materials to further process them into paper products. The paper packaging industry has a wide variety of products, mainly including three categories: corrugated paper, honeycomb paper, and embossed paper. Paper packaging derived from these three categories includes cartons, paper boxes, paper bags, paper cans, and pulp molding.

[0003] For example, an energy-saving wastewater and waste gas purification device for paper product production, disclosed in CN115318026A, includes a wastewater treatment tank and a waste gas treatment tank. A support frame is bolted to the upper side of the wastewater treatment tank. The waste gas treatment tank is positioned above the wastewater treatment tank and bolted to the upper end of the support frame. A connecting hood is provided at the upper end of the wastewater treatment tank, and a vent pipe is provided at the upper end of the connecting hood. A vent is provided on the lower surface of the waste gas treatment tank. Through the designed connecting hood and support frame, the waste gas treatment tank is installed on the wastewater treatment tank via the support frame during use. The connecting hood and vent connect the interior of the wastewater treatment tank and the interior of the waste gas treatment tank. The gas generated during wastewater treatment is introduced into the waste gas treatment tank for further treatment, thus avoiding the problem of poor waste gas treatment during wastewater treatment. Furthermore, using this device in conjunction with other treatment methods can reduce energy consumption.

[0004] However, paper products generate a large amount of VOCs (volatile organic compounds) during production. These waste gases mainly come from printing, adhesive bonding, and other processes, and include harmful substances such as benzene, toluene, and xylene. In order to reduce the impact on the environment, VOCs waste gases need to be treated before being discharged. Before the waste gas enters the main treatment equipment, it usually needs to be filtered and cooled. Filtration is required before cooling to reduce the impact of particulate matter in the waste gas on the cooling effect. The more thorough the particulate matter filtration, the better the subsequent cooling effect of the waste gas, which helps to reduce damage to subsequent equipment and improve the waste gas treatment efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a wastewater and exhaust gas purification device for paper product manufacturing, in order to solve the problem that existing exhaust gas treatment equipment has a poor filtration effect on particulate matter in exhaust gas, which affects the subsequent cooling process and reduces the efficiency of exhaust gas treatment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a wastewater and waste gas purification device for paper product manufacturing, comprising a base plate and support rods fixedly installed around the top of the base plate, wherein the top of the support rods is fixedly connected to the same mounting plate; Also includes: A wastewater tank is fixedly connected to the top side of the base plate, and an exhaust gas tank is fixedly connected to the top of the mounting plate. An exhaust gas treatment component is installed inside the exhaust gas tank, and a wastewater treatment component is installed inside the wastewater tank. The exhaust gas treatment assembly includes a fixed plate and a filter screen that are fixedly connected to one side of the exhaust gas box. A side box is fixedly connected to one side of the inner wall of the exhaust gas box. A rectangular sliding groove is opened on one side of the front of the side box. A connecting rod is slidably connected inside the rectangular sliding groove. A pressure rod is fixedly connected to one side of the connecting rod.

[0007] Preferably, four drive motors are fixedly installed on one side of the inner chamber of the side box, and a main gear is fixedly connected to the output end of the drive motor. A toothed belt is installed on the other side of the inner chamber of the side box, and the main gear meshes with the toothed belt. A sliding rod is slidably connected to the bottom of the lower pressure rod, and the bottom of the sliding rod is fixedly connected to the pressure plate. There are at least two sliding rods. A pressure plate is slidably installed on the bottom of the lower pressure rod. A collection box is fixedly connected to one side of the inner bottom surface of the exhaust gas box. A baffle plate is symmetrically rotated and installed on the outer side of the lower pressure rod. Two fixing rods are fixedly connected to one side of the inner top surface of the exhaust gas box.

[0008] By adopting the above technical solution, the external exhaust gas and the exhaust gas in the wastewater are filtered by the filter screen, while the baffle plate blocks and guides the exhaust gas. This facilitates the downward scraping of residual material on the outside of the filter screen and also ensures that the exhaust gas is in full contact with the filter screen, thereby improving the subsequent cooling effect and exhaust gas treatment efficiency.

[0009] Preferably, a spring is sleeved on the outer side of the slide rod, the top end of the spring is fixedly connected to the lower pressure rod, the bottom end of the spring is fixedly connected to the pressure plate, and the two sides of the pressure plate are symmetrically fixedly connected to the bonding plates. Two side plates are symmetrically fixedly connected to the side of the lower pressure rod away from the filter screen, and two inner plates are fixedly connected vertically and horizontally to one side of the side plate.

[0010] By adopting the above technical solution, as the lower pressure rod moves horizontally at a low position, the bonding plate and the pressing plate will tilt and rise. The pressing plate drives the slide rod to slide into the lower pressure rod, and the pressing plate compresses the spring, which realizes the guiding, pressing and spreading of the particles by the pressing plate, reducing the accumulation of collected particles on one side.

[0011] Preferably, a vertical rod is fixedly connected between the upper and lower inner plates, and a baffle plate is rotatably connected to the middle of the outer side of the vertical rod. A torsion spring is sleeved on the outer side of the vertical rod, and the two ends of the torsion spring are fixedly connected to the inner plate and the baffle plate respectively. Two fixing rods are symmetrically fixedly connected to one side of the inner top surface of the exhaust gas box, and the fixing rods are located on the side of the baffle plate away from the filter screen.

[0012] By adopting the above technical solution, the baffle plate will rotate when squeezed by the fixed rod. The baffle plate acts on the torsion spring. When the baffle plate moves away from the fixed rod, the elastic force of the torsion spring drives the baffle plate to rotate back to its original position, which facilitates intermittent closing and conduction, thereby prolonging the contact time between the exhaust gas and the filter screen and improving the filtration effect.

[0013] Preferably, two sealing covers are symmetrically fixedly connected in the middle of the interior of the exhaust gas box, and a connecting pipe is fixedly connected between the two sealing covers. There are no fewer than four connecting pipes. A water pipe is fixedly installed in the middle of the top of the exhaust gas box, and an annular cover is fixedly connected to the bottom of the water pipe. The annular cover is fitted onto the outside of the connecting pipe.

[0014] By adopting the above technical solution, the filtered exhaust gas is guided into the connecting pipe through the sealing cover. The water pipe is connected to the external high-pressure water pipe, and the water is sprayed out from the spray pipe through the annular cover, which facilitates uniform cooling of the exhaust gas in the connecting pipe.

[0015] Preferably, spray pipes are symmetrically fixedly installed on the inner wall of the annular cover, an activated carbon plate is fixedly installed on the other side of the interior of the exhaust gas box, an upper box door is hinged to one side of the front of the exhaust gas box, an air inlet pipe is fixedly installed on one side of the exhaust gas box, and an exhaust pipe is fixedly installed on the other side of the exhaust gas box.

[0016] By adopting the above technical solution, the cooled exhaust gas is treated by adsorption by activated carbon plates and discharged through the exhaust pipe.

[0017] Preferably, a connecting cover is fixedly connected to the top of the wastewater tank, the wastewater tank is connected to the exhaust gas tank through the connecting cover, a lower tank door is hinged to one side of the front of the wastewater tank, the wastewater treatment assembly includes an adding pipe fixedly connected to the top of the wastewater tank, and a fixing cover is fixedly connected to the inner top surface of the wastewater tank by bolts.

[0018] By adopting the above technical solution, the waste gas in the wastewater tank enters the waste gas tank for treatment through the connecting hood, and the wastewater is added to the wastewater tank through the addition pipe.

[0019] Preferably, a lower servo motor is fixedly installed at the top center of the wastewater tank, a scraper is fixedly connected to the inner top surface of the fixed cover, a conical filter screen is fixedly connected to the output end of the lower servo motor, and a circular groove is opened in the bottom center of the fixed cover.

[0020] By adopting the above technical solution, the wastewater is filtered through a conical filter screen, the pulp residue falls into the fixed cover, and the water flows into the wastewater tank through the conical filter screen and the circular trough.

[0021] Preferably, side servo motors are symmetrically fixedly installed on both sides of the wastewater tank, and a stirring rod is fixedly connected to the output end of the side servo motor. A discharge pipe is fixedly connected to the lower part of one side of the waste gas tank.

[0022] By adopting the above technical solution, the lower servo motor drives the scraping rod to rotate, and the scraping rod stirs and scrapes the outside of the conical filter screen, which helps to reduce the residual blockage on the conical filter screen. The treatment agent is added to the wastewater tank through the addition pipe, and the side servo motor drives the stirring rod to rotate, and the stirring rod stirs and mixes the treatment agent and wastewater.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting up an exhaust gas treatment component, utilizing the cooperation of a filter screen, toothed belt, pressure rod, baffle plate, and clamping plate, the external exhaust gas and exhaust gas in the wastewater are filtered by the filter screen while the pressure rod slides along a rectangular trajectory. The baffle plate blocks and guides the exhaust gas, which facilitates the downward scraping of residual material on the outside of the filter screen and ensures full contact between the exhaust gas and the filter screen, maintaining efficient separation of particulate matter. At the same time, the clamping plate guides and presses the particulate matter, reducing the accumulation of collected particulate matter on one side and improving the pressing and collection effect. It also avoids the situation where the pressure rod pushes the particulate matter upward when it rises, hindering the collection of particulate matter. Furthermore, in conjunction with the subsequent spray pipe for annular spraying, the filtration effect of particulate matter in the exhaust gas is improved, thereby also improving the subsequent cooling effect and exhaust gas treatment efficiency. The specific details are as follows: 1. By setting up an exhaust gas treatment component, external exhaust gas enters the exhaust gas box through the intake pipe. The filter screen filters particulate matter in the exhaust gas. The operator starts the drive motor, which drives the main gear to rotate. The main gear drives the toothed belt to rotate. The toothed belt drives the lower pressure rod to move through the connecting rod. The connecting rod slides inside the rectangular slide groove. The lower pressure rod descends and scrapes the filter screen. The lower pressure rod drives the pressing plate to descend. The pressing plate drives the bonding plate to press the collection box. The scraped particulate matter falls into the collection box for collection. Because the top surface of the collection box is inclined, as the lower pressure rod moves horizontally at a low position, the bonding plate and the pressing plate will tilt and rise. The pressing plate drives the slide rod to slide into the lower pressure rod. The pressing plate compresses the spring, realizing the guiding, pressing and spreading of particulate matter by the pressing plate, reducing the accumulation of collected particulate matter on one side. This design improves the compaction and collection effect, and avoids the situation where the lowering rod pushes particles upwards and hinders particle collection. When the lowering rod approaches the fixed rod, it will drive the side plate and the baffle plate to move. The baffle plate will rotate under the pressure of the fixed rod. The baffle plate acts on the torsion spring. When the baffle plate moves away from the fixed rod, the elastic force of the torsion spring will drive the baffle plate to rotate back to its original position, which facilitates intermittent closure and conduction. This is used to prolong the contact time between the exhaust gas and the filter screen, and improve the filtration effect. The filtered exhaust gas is guided into the connecting pipe through the sealing cover. The water pipe is connected to the external high-pressure water pipe. The water is sprayed out from the spray pipe through the annular cover, which facilitates uniform cooling of the exhaust gas in the connecting pipe and reduces the impact of particulate matter in the exhaust gas on the cooling effect. Finally, the cooled exhaust gas is treated by activated carbon plate adsorption and discharged through the exhaust pipe. 2. By setting up a wastewater treatment component, the exhaust gas in the wastewater tank enters the exhaust gas tank for treatment through a connecting hood. Wastewater is added to the wastewater tank through an addition pipe. The wastewater is filtered through a conical filter screen, and pulp residue falls into a fixed hood. The water flows into the wastewater tank through the conical filter screen and a circular trough. The lower servo motor drives the scraper to rotate, and the scraper agitates and scrapes the outside of the conical filter screen to reduce the residual obstruction of residue on the conical filter screen. The treatment agent is added to the wastewater tank through an addition pipe, and the side servo motor drives the stirring rod to rotate. The stirring rod agitates and mixes the treatment agent and wastewater. The treated wastewater is discharged through a discharge pipe, realizing the unified recycling and treatment of wastewater.

[0027] Please see Figure 1 - Figure 3 The present invention provides a technical solution: a wastewater and waste gas purification device for paper product production, including a base plate 1 and support rods 2 fixedly installed around the top of the base plate 1. The top of the support rods 2 is fixedly connected to the same mounting plate 3, and multiple support rods 2 are used to stably support the mounting plate 3.

[0028] A wastewater tank 4 is fixedly connected to the top side of the base plate 1, and an exhaust gas tank 5 is fixedly connected to the top of the mounting plate 3. An exhaust gas treatment component 6 is installed inside the exhaust gas tank 5.

[0029] like Figure 3 - Figure 12 As shown, the exhaust gas treatment component 6 includes a fixed plate 61 and a filter screen 62 fixedly connected to one side of the exhaust gas box 5. A side box 63 is fixedly connected to one side of the inner wall of the exhaust gas box 5. A rectangular slide groove 64 is provided on one side of the front of the side box 63. A connecting rod 68 is slidably connected inside the rectangular slide groove 64. A pressing rod 69 is fixedly connected to one side of the connecting rod 68. The connecting rod 68 will slide inside the rectangular slide groove 64, thereby keeping the pressing rod 69 sliding in a rectangular trajectory.

[0030] Four drive motors 65 are fixedly installed on one side of the interior of the side chamber 63. The output end of the drive motor 65 is fixedly connected to the main gear 66. A toothed belt 67 is installed on the other side of the interior of the side chamber 63. The main gear 66 and the toothed belt 67 are meshed together. A slide rod 610 is slidably connected to the bottom of the lower pressure rod 69. The bottom of the slide rod 610 is fixedly connected to the pressure plate 611. There are at least two slide rods 610 to maintain the stable lifting and lowering of the pressure plate 611. The pressure plate 611 is slidably installed on the bottom of the lower pressure rod 69. A collection box 614 is fixedly connected to one side of the inner bottom surface of the exhaust gas box 5. A baffle plate 618 is symmetrically rotated and installed on the outer side of the lower pressure rod 69. Two fixing rods 620 are fixedly connected to one side of the inner top surface of the exhaust gas box 5. The fixing rods 620 are used to block the baffle plate 618 and keep the baffle plate 618 intermittently closing and opening, thereby prolonging the contact time between the exhaust gas and the filter screen 62 and improving the filtration effect.

[0031] A spring 612 is sleeved on the outer side of the slide rod 610. The top end of the spring 612 is fixedly connected to the lower pressure rod 69, and the bottom end of the spring 612 is fixedly connected to the pressure plate 611. The spring 612 facilitates the springback and reset of the pressure plate 611. Adhesive plates 613 are symmetrically fixedly connected to both sides of the pressure plate 611. Two side plates 615 are symmetrically fixedly connected to the side of the lower pressure rod 69 away from the filter screen part 62. Two inner plates 616 are fixedly fixedly connected vertically to one side of the side plate 615.

[0032] A vertical rod 617 is fixedly connected between the upper and lower inner plates 616. A baffle plate 618 is rotatably connected to the middle of the outer side of the vertical rod 617. A torsion spring 619 is sleeved on the outer side of the vertical rod 617. The two ends of the torsion spring 619 are fixedly connected to the inner plate 616 and the baffle plate 618 respectively. There are at least two torsion springs 619, which are used to keep the baffle plate 618 rotating and resetting. Two fixing rods 620 are symmetrically fixedly connected to one side of the inner top surface of the exhaust gas box 5. The fixing rods 620 are located on the side of the baffle plate 618 away from the filter screen part 62.

[0033] Two sealing covers 621 are symmetrically fixedly connected in the middle of the interior of the exhaust gas box 5. A connecting pipe 622 is fixedly connected between the two sealing covers 621. There are no fewer than four connecting pipes 622. A water pipe 623 is fixedly installed in the middle of the top of the exhaust gas box 5. An annular cover 624 is fixedly connected to the bottom of the water pipe 623. The annular cover 624 is fitted onto the outside of the connecting pipe 622. The filtered exhaust gas enters the connecting pipe 622 through the sealing cover 621 on one side, and is then adsorbed by the activated carbon plate 626 through the sealing cover 621 on the other side.

[0034] Spray pipes 625 are symmetrically fixedly installed on the inner wall of the annular cover 624. An activated carbon plate 626 is fixedly installed on the other side of the interior of the exhaust gas box 5. An upper box door 8 is hinged to one side of the front of the exhaust gas box 5. By opening the upper box door 8, it is easy to pull out the collection box 614 for cleaning. An air inlet pipe 9 is fixedly installed on one side of the exhaust gas box 5, and an exhaust pipe 10 is fixedly installed on the other side of the exhaust gas box 5.

[0035] Example 1: As Figure 1 - Figure 12 As shown, external exhaust gas enters the exhaust gas box 5 through the intake pipe 9. The filter screen 62 filters the particulate matter in the exhaust gas. The operator starts the drive motor 65, which drives the main gear 66 to rotate. The main gear 66 drives the toothed belt 67 to rotate. The toothed belt 67 drives the lowering rod 69 to move through the connecting rod 68. The connecting rod 68 slides inside the rectangular slide groove 64. The lowering rod 69 lowers and scrapes the filter screen 62. The lowering rod 69 drives the pressing plate 611 to descend. The pressing plate 611 drives the bonding plate 613 to press the collection box 614. The scraped particulate matter falls into the collection box 614 and is collected.

[0036] Because the top surface of the collection box 614 is inclined, as the pressing rod 69 moves horizontally at a low position, the bonding plate 613 and the pressing plate 611 will tilt and rise. The pressing plate 611 drives the sliding rod 610 to slide into the pressing rod 69, and the pressing plate 611 compresses the spring 612, which realizes the guiding, pressing and spreading of the particles by the pressing plate 611, reduces the accumulation of collected particles on one side, improves the pressing and collection effect, and also avoids the situation where the pressing rod 69 pushes the particles upward when it rises, thus hindering the collection of particles.

[0037] When the downward pressure rod 69 approaches the fixed rod 620, it will drive the side plate 615 and the baffle plate 618 to move. The baffle plate 618 will rotate under the pressure of the fixed rod 620. The baffle plate 618 acts on the torsion spring 619. When the baffle plate 618 moves away from the fixed rod 620, the elastic force of the torsion spring 619 will drive the baffle plate 618 to rotate back to its original position, which facilitates intermittent closing and conduction, and is used to prolong the contact time between the exhaust gas and the filter screen 62, thereby improving the filtration effect.

[0038] The filtered exhaust gas is guided into the connecting pipe 622 through the sealing cover 621. The water pipe 623 is connected to the external high-pressure water pipe. The water is sprayed out from the spray pipe 625 through the annular cover 624, which facilitates uniform cooling of the exhaust gas in the connecting pipe 622 and reduces the impact of particulate matter in the exhaust gas on the cooling effect. Finally, the cooled exhaust gas is adsorbed by the activated carbon plate 626 and discharged through the exhaust pipe 10.

[0039] like Figure 1 and Figure 13 - Figure 14As shown, the wastewater tank 4 is equipped with a wastewater treatment component 7 inside. A connecting cover 11 is fixedly connected to the top of the wastewater tank 4. The wastewater tank 4 is connected to the exhaust gas tank 5 through the connecting cover 11. A lower door 12 is hinged to one side of the front of the wastewater tank 4. The wastewater treatment component 7 includes an adding pipe 71 fixedly connected to the top of the wastewater tank 4. A fixing cover 72 is fixedly connected to the inner top surface of the wastewater tank 4 by bolts.

[0040] A lower servo motor 73 is fixedly installed at the top center of the wastewater tank 4. A scraper 74 is fixedly connected to the inner top surface of the fixed cover 72. A conical filter screen 75 is fixedly connected to the output end of the lower servo motor 73. A circular groove 76 is opened in the middle of the bottom of the fixed cover 72.

[0041] Side servo motors 77 are symmetrically fixedly installed on both sides of the wastewater tank 4. A stirring rod 78 is fixedly connected to the output end of the side servo motor 77. A discharge pipe 79 is fixedly connected to the lower part of one side of the exhaust gas tank 5. The stirring rod 78 is driven to rotate by the side servo motor 77, which facilitates the full mixing of the treatment agent and the wastewater.

[0042] Example 2: Figure 13 - Figure 14 As shown, the exhaust gas in wastewater tank 4 enters the exhaust gas tank 5 for treatment through the connecting hood 11. Wastewater is added to wastewater tank 4 through the adding pipe 71. The wastewater is filtered through the conical filter screen 75, and the pulp residue falls into the fixed hood 72. The water flows into wastewater tank 4 through the conical filter screen 75 and the circular groove 76. The lower servo motor 73 drives the scraping rod 74 to rotate. The scraping rod 74 stirs and scrapes the outside of the conical filter screen 75 to reduce the residual blockage of the residue on the conical filter screen 75. The treatment agent is added to wastewater tank 4 through the adding pipe 71. The side servo motor 77 drives the stirring rod 78 to rotate. The stirring rod 78 stirs and mixes the treatment agent and wastewater. The treated wastewater is discharged through the discharge pipe 79, realizing the unified recycling and treatment of wastewater.

[0043] Working principle: When using this device, firstly, as... Figure 1 - Figure 14As shown, external exhaust gas enters the exhaust gas box 5 through the intake pipe 9. The filter screen 62 filters particulate matter in the exhaust gas. The operator starts the drive motor 65, and the connecting rod 68 slides inside the rectangular slide groove 64. The pressing rod 69 descends to scrape the filter screen 62. The pressing rod 69 drives the pressing plate 611 to descend, and the pressing plate 611 drives the bonding plate 613 to press the collection box 614. The scraped particulate matter falls into the collection box 614 for collection. The pressing plate 611 guides and presses the particulate matter to spread it out, reducing the accumulation of collected particulate matter on one side. The baffle plate 618 facilitates intermittent closing and opening, which is used to prolong the contact time between the exhaust gas and the filter screen 62 and improve the filtration effect. The filtered exhaust gas is guided into the connecting pipe 622 through the sealing cover 621. Water is sprayed out from the spray pipe 625 through the annular cover 624, which facilitates the cleaning of the water. The exhaust gas in the connecting pipe 622 is uniformly cooled. After cooling, the exhaust gas is adsorbed by the activated carbon plate 626 and discharged through the exhaust pipe 10. The exhaust gas in the wastewater tank 4 enters the exhaust gas tank 5 for treatment through the connecting cover 11. The wastewater is added to the wastewater tank 4 through the adding pipe 71. The wastewater is filtered through the conical filter screen 75. The pulp residue falls into the fixed cover 72. The water flows into the wastewater tank 4 through the conical filter screen 75 and the circular groove 76. The lower servo motor 73 drives the scraping rod 74 to rotate. The scraping rod 74 stirs and scrapes the outside of the conical filter screen 75 to reduce the residual blockage of the residue on the conical filter screen 75. The treatment agent is added to the wastewater tank 4 through the adding pipe 71. The side servo motor 77 drives the stirring rod 78 to rotate. The stirring rod 78 stirs and mixes the treatment agent and wastewater. The treated wastewater is discharged through the discharge pipe 79, realizing the unified recycling and treatment of wastewater.
