Description

Technical Field

[0001] The present invention relates to the technical field of waste pollution filtration equipment, and specifically to an air solid waste pollution filtration device and method for a pulp production workshop. Background Art

[0002] During the pulp production process, the air in the workshop often contains a large amount of solid waste pollutants, such as fibers, solid particles, etc. If such solid waste pollution is directly discharged without effective treatment, it will cause multiple pollutions to the surrounding soil, water bodies and atmospheric environment. It not only violates the requirements of environmental protection regulations, but may also trigger ecological chain reactions. Therefore, carrying out efficient filtration treatment for the solid waste pollution carried by air is a necessary link for the pulp industry to achieve green production.

[0003] Currently, most pulp production workshops use filter cloth as the main filtration medium. However, in the high-humidity environment of the pulp workshop, the filter cloth has many insurmountable defects. First of all, high humidity makes the filter cloth extremely easy to get damp. After getting damp, the mechanical strength of the filter cloth decreases, shortening its service life. Secondly, solid waste pollutants such as fibers are extremely easy to adhere to the surface and internal pores of the filter cloth, causing the filter cloth to become blocked. This not only increases the filtration resistance and reduces the filtration efficiency, but also frequent blockages require a large amount of time and manpower for cleaning. Traditional cleaning methods often require removing the filter cloth and using methods such as water washing and patting to remove the attached pollutants, which is a cumbersome process and has a high labor intensity. More seriously, in a humid and pollutant-attached environment, the filter cloth is extremely easy to breed mold. The breeding of mold will not only further reduce the filtration performance of the filter cloth, resulting in the filtered air still containing more pollutants and affecting the air quality, but also the diffusion of mold spores may pose a hazard to the physical health of the workshop staff.

[0004] In summary, the existing filter cloth filtration method cannot meet the better filtration treatment effect in the high-humidity environment of the pulp workshop, and there is an urgent need for a new type of air solid waste pollution filtration device to solve these problems. Summary of the Invention

[0005] The purpose of the present invention is to provide an air solid waste pollution filtering device and method for a pulp production workshop, so as to solve the problems raised in the above-mentioned background technology. In the high-humidity environment of the pulp workshop, the filter cloth is extremely prone to getting damp. After getting damp, the mechanical strength of the filter cloth decreases, shortening its service life. Secondly, solid waste pollutants such as fibers are extremely likely to adhere to the surface and internal pores of the filter cloth, causing blockage of the filter cloth. Traditional cleaning methods often require the filter cloth to be disassembled and the attached pollutants to be removed by methods such as water washing and beating. The process is cumbersome and the labor intensity is high. At the same time, the filter cloth is extremely prone to breeding mold. The breeding of mold will not only further reduce the filtering performance of the filter cloth, resulting in the filtered air still containing more pollutants, affecting the air quality and posing a hazard to the physical health of the workshop staff.

[0006] To achieve the above purpose, the present invention provides the following technical solution: An air solid waste pollution filtering device for a pulp production workshop, including a solid waste pollution treatment box, a partition fixedly installed inside the solid waste pollution treatment box, and an air inlet pipe fixedly installed through one side of the solid waste pollution treatment box.

[0011] Furthermore, the isolation mechanism includes a limit cylinder and a rotating shaft. The limit cylinder is horizontally and fixedly installed on the outside of the top side of the scraping box close to the extrusion plate through a bracket. The rotating shaft penetrates and is rotatably installed inside the limit cylinder.

[0013] Furthermore, a rotating rod is horizontally rotatably installed inside the bottom side of the solid waste pollution treatment box close to the bottom ends of the two arc-shaped bumps.

A resisting spring is fixedly arranged between one side of the slider and one side of the fixing plate.

[0015] The present invention also provides a method for an air solid waste pollution filtering device in a pulp production workshop, including the following steps:

[0016] S1: During use, first, the rotation of the output shaft of the driving motor drives the driving gear and one of the driving rollers to rotate, thereby driving the solid particle filter cloth belt sleeved on the outside of the driving roller one and the driving roller two to switch, so as to timely replace the solid particle filter cloth belt at the output end of the air inlet pipe, and convey the solid particle filter cloth belt with fiber particles adhered thereto to the top of the cleaning and compressing mechanism;

[0017] S2: Through the operation of the cleaning and compressing mechanism, the fiber particle impurities on the surface of the solid particle filter cloth belt are mechanically peeled off;

[0018] S3: When the solid particle filter cloth belt is being switched and cleaned, the extrusion and sterilization mechanism can be triggered to operate synchronously, so that the bactericide can be sprayed onto the surface of the cleaned solid particle filter cloth belt, and then, with the cooperation of the pressure roller extrusion, the bacteria-containing sewage inside the solid particle filter cloth belt can be discharged;

[0019] S4: Then, combined with the conduction of the gas guide pipe and the discharge pipe, the filtered and heated gas is blown onto the surface of the disinfected and extruded solid particle filter cloth belt to dry it;

[0020] S5: At the same time, during cleaning, through the intermittent knocking and vibration of the knocking block, the solid particle filter cloth belt is caused to vibrate at a high frequency during spraying, so that the bactericide can better penetrate into the fiber gaps inside the solid particle filter cloth belt.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. When this air-solid waste pollution filtration device is in use, through the design of continuous transmission of the solid particle filter cloth belt, it can timely convey the solid particle filter cloth belt to the top of the cleaning and compressing mechanism before it is blocked by adhering wet fiber particles. Synchronously switch to a new solid particle filter cloth belt to maintain the filtration continuity, avoiding the cumbersome process of manual disassembly and cleaning after the traditional solid particle filter cloth belt is blocked. Cooperating with the operation of the cleaning and compressing mechanism, it can mechanize the stripping of fiber particle impurities on the surface of the solid particle filter cloth belt, and complete the cleaning without manual operation. The stripped fiber particles are pressed into blocks after extrusion and dehydration and finally transported and discharged for recycling. Thus, it can not only realize the recycling and reuse of fiber resources, reduce the waste of raw materials, but also reduce the subsequent sewage treatment and solid waste treatment costs by reducing the moisture content of solid waste. At the same time, timely removing the wet fiber attachments on the surface of the solid particle filter cloth belt destroys the wet environment and the source of organic matter for mold growth, inhibits the reproduction of microorganisms from the source, and improves the air quality and equipment hygiene conditions in the workshop;

[0023] 2. When the solid particle filter cloth belt is being switched and cleaned, it can trigger the synchronous operation of the extrusion and sterilization mechanism, so that the bactericide can be sprayed onto the surface of the cleaned solid particle filter cloth belt. Then, with the cooperation of the pressing roller extrusion, the bacteria-containing sewage inside the solid particle filter cloth belt is discharged, restoring partial air permeability of the solid particle filter cloth belt. Then, combined with the conduction of the air duct and the discharge pipe, the filtered and heated gas is blown onto the surface of the disinfected and extruded solid particle filter cloth belt to dry it, making it recyclable and ensuring its filtration treatment effect. At the same time, during the cleaning process, through the intermittent knocking and vibration of the knocking block, the solid particle filter cloth belt vibrates at a high frequency when spraying, so that the bactericide can better penetrate into the fiber gaps inside the solid particle filter cloth belt, solving the defect that the traditional static spraying only acts on the surface, especially improving the deep sterilization effect of the wet solid particle filter cloth belt.

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Embodiment 1: Please refer to Figure 1 - Figure 7, An air solid waste pollution filtration device for a pulp production workshop, comprising a solid waste pollution treatment box 1, a partition plate 2 fixedly installed inside the solid waste pollution treatment box 1, and an air inlet pipe 6 fixedly installed through one side of the solid waste pollution treatment box 1. On both sides of the partition plate 2 inside the solid waste pollution treatment box 1, two driving rollers 3 and two driving rollers 4 are symmetrically arranged respectively. An external fitting and driving connection of the two driving rollers 3 and the two driving rollers 4 is provided with a solid particle filter cloth belt 5. On both sides of the bottom end of the partition plate 2 inside the solid waste pollution treatment box 1, a cleaning and compressing mechanism and an extrusion and sterilization mechanism are respectively arranged; the cleaning and compressing mechanism includes a scraping box 9 and an extrusion plate 12. The scraping box 9 is fixedly installed inside one side of the bottom end of the solid waste pollution treatment box 1 close to one of the driving rollers 3, and the extrusion plate 12 is slidably installed inside one side of the scraping box 9.

[0038] On the outer side of one side of one of the driving rollers 3 close to the bottom end of the solid waste pollution treatment box 1, a driving gear 7 is fixedly installed. On the outer side of the solid waste pollution treatment box 1 close to the driving gear 7, a driving motor 8 is fixedly installed through a bracket. The output end of the driving motor 8 is fixedly installed at the middle position on one side of the driving gear 7. On one side of the driving gear 7, a driving and extrusion mechanism and an isolation mechanism are arranged.

[0039] The driving and extrusion mechanism includes a gear rod 10 and a turntable 11. The gear rod 10 is rotatably and engagingly installed through the inside of one side of the solid waste pollution treatment box 1 close to the driving gear 7. The turntable 11 is fixedly installed at the rotating through end of the gear rod 10. The gear end of the gear rod 10 is meshed and connected with one side of the driving gear 7. On the outer edge of one side of the turntable 11 away from the gear rod 10, a limit post 13 is fixedly installed. A limit frame 14 is longitudinally arranged through and slidably on the outside of the limit post 13.

[0040] On both sides of the extrusion plate 12 close to the limit frame 14, sliding rods 15 are symmetrically fixedly installed. One ends of the sliding rods 15 are all installed through and slidably on the outside of one side of the scraping box 9. The penetrating end of one of the sliding rods 15 is fixedly installed at the middle position on one side of the limit frame 14. The outer surface of one side of the top end of the scraping box 9 is in contact and fit with the outer side of the bottom end of the solid particle filter cloth belt 5.

[0041] Inside the scraping box 9 on the side away from the extrusion plate 12, a small belt conveyor 16 is horizontally arranged through. On the conveyor belt of the small belt conveyor 16, a number of hanging teeth 19 are fixedly installed at equal intervals. Inside the bottom end of the scraping box 9 close to the small belt conveyor 16, a number of liquid discharge holes 17 are arranged through. Between the bottom ends of the number of liquid discharge holes 17, a guiding pipe 18 is connected and communicated. The output end of the guiding pipe 18 penetrates through the partition plate 2 and is placed inside the bottom end of the solid waste pollution treatment box 1 close to the driving roller 4.

[0042] The isolation mechanism includes a limit cylinder 20 and a rotating shaft 21. The limit cylinder 20 is horizontally and fixedly installed outside the top side of the scraping box 9 close to the pressing plate 12 through a bracket. The rotating shaft 21 is rotatably installed through the inside of the limit cylinder 20. A torsion spring 22 is fixedly connected between the penetrating end of the rotating shaft 21 and the outside of the limit cylinder 20. An isolation belt 23 is wound on the outer side of the rotating shaft 21 inside the limit cylinder 20. One end of the isolation belt 23 is fixedly connected to the outer side of one side of the rotating shaft 21. The other end of the isolation belt 23 penetrates through the limit cylinder 20 and the inside of the scraping box 9 and is fixedly connected to the top side of the pressing plate 12.

[0043] In this embodiment, when the air solid waste pollution filtering device is in use, first, the output pipe of the internal ventilation component of the workshop is connected to the intake end of the intake pipe 6, so as to introduce the air in the pulp production workshop into the internal of the solid waste pollution treatment box 1 for air solid waste pollution filtering. The input end of the liquid supply pump 24 is connected and conducted through a conduit to the inside of an existing bactericide storage tank to ensure the subsequent supply of bactericide. At the same time, the one-way discharge valve pipe 36 is connected to an external sewage pipe. Finally, a collection box is conductively placed at the output end of the existing small belt conveyor 16 to recycle the fibers.

[0044] When the device has been used for a certain period of time, the driving motor 8 can be started through control. The rotation of the output shaft of the driving motor 8 drives the driving gear 7 and one of the driving rollers 3 to rotate, thereby driving the switching of the solid particle filter cloth belt 5 sleeved on the outer surfaces of the driving roller 3 and the driven roller 4, so as to timely replace the solid particle filter cloth belt 5 at the output end of the air inlet pipe 6 and ensure its continuous use effect. When the solid particle filter cloth belt 5 rotates and switches, the fiber particle impurities adhered to its surface will be transported to the top of the scraping box 9. Through the setting that the top of the scraping box 9 is in contact with the bottom surface of the solid particle filter cloth belt 5, the fiber particle impurities adhered to the surface of the solid particle filter cloth belt 5 are scraped off into the interior of the scraping box 9. When the driving gear 7 rotates, it drives the gear rod 10 engaged on one side to rotate synchronously. Through the rotation of the gear rod 10, the turntable 11 on one side is driven to rotate. Through the rotation of the turntable 11, the limit post 13 on one side is driven to rotate. With the installation and cooperation of the limit frame 14 and the slide rod 15, when the turntable 11 drives the limit post 13 to rotate, the slide rod 15 and the extrusion plate 12 will reciprocate and extrude inside the scraping box 9, so as to extrude the scraped fiber particle impurities into blocks. At the same time, a certain amount of moist water inside the fiber particle impurities can also be extruded and discharged during extrusion. The extruded water is guided into the internal of the one-way discharge valve pipe 36 through the drain hole 17 and the guiding pipe 18, and can be discharged later by opening the one-way discharge valve pipe 36. During extrusion, through the start of the existing small belt conveyor 16 and the setting of a number of hanging teeth 19 on its belt surface, the extruded fiber particle impurities are carried and transported out for recycling. Thus, when the air solid waste pollution filtering device is in use, through the design of continuous transmission of the solid particle filter cloth belt 5, the solid particle filter cloth belt 5 can be timely transported to the top of the cleaning and compressing mechanism before it is blocked due to adhesion of moist fiber particles, and a new solid particle filter cloth belt 5 is synchronously switched in to maintain the filtering continuity, avoiding the cumbersome process of manual disassembly and cleaning after the traditional solid particle filter cloth belt 5 is blocked. With the operation of the cleaning and compressing mechanism, the fiber particle impurities on the surface of the solid particle filter cloth belt 5 are mechanized peeled off, and the cleaning can be completed without manual operation. The peeled fiber particles are pressed into blocks after extrusion and dehydration and finally transported out for recycling. Thus, it can not only realize the recycling and reuse of fiber resources and reduce the waste of raw materials, but also reduce the subsequent sewage treatment and solid waste treatment costs by reducing the moisture content of solid waste. At the same time, the moist fiber attachments on the surface of the solid particle filter cloth belt 5 are timely removed, destroying the moist environment and the source of organic matter for mold growth, inhibiting the reproduction of microorganisms from the source, and improving the air quality and equipment hygiene conditions in the workshop.

[0045] It should also be noted that when the extrusion plate 12 reciprocates, it will drive the rotating shaft 21 inside the limiting cylinder 20 on the top side to rotate and the insulating belt 23 to stretch, so that when the extrusion plate 12 is pushed to one side of the small belt conveyor 16, its top opening will be blocked by the stretched insulating belt 23, preventing the impurities swept away at this time from falling to the other side of the extrusion plate 12, resulting in the situation that they will not be squeezed and cleaned later, thereby ensuring the overall extrusion and discharge effect. At the same time, when the extrusion plate 12 moves back, the torsion spring 22 will drive the rotating shaft 21 to rotate, thereby driving the insulating belt 23 to reel and reset, thereby ensuring the overall stability of use.

[0046] Example 2: Please refer to Figure 8 - Figure 11 This embodiment further explains Example 1. The extrusion sterilization mechanism includes two pressing rollers 32 and two arc-shaped protrusions 26. The two pressing rollers 32 are symmetrically and tightly arranged on one side of the solid particle filter cloth belt 5 close to the transmission roller 2 4. The two arc-shaped protrusions 26 are fixedly installed on the outside of both ends of one of the transmission rollers 2 4.

[0047] A liquid supply pump 24 is fixedly installed on the outside of one side of the solid waste pollution treatment box 1, and a spray pipe 25 is fixedly installed laterally on the side of the partition 2 away from the scraper box 9 through a bracket. The input end of the spray pipe 25 is connected and fixed to the output end of the liquid supply pump 24, and the output end of the spray pipe 25 is facing the outside of the top end of the solid particle filter cloth belt 5. A one-way discharge valve pipe 36 is fixedly penetrated inside the solid waste pollution treatment box 1 near the bottom end of the spray pipe 25.

[0048] A rotating rod 28 is installed for horizontal rotation inside the solid waste pollution treatment box 1 near the bottom end of the two arc-shaped protrusions 26, and a rotating frame 27 is fixedly installed on the outside of the rotating rod 28 near the two arc-shaped protrusions 26. The rotating frame 27 is designed in an inclined 7-shape, and a knocking block 29 is connected and fixed between the outside of the rotating frame 27 near the top of the solid particle filter cloth belt 5.

[0049] An air duct 34 is fixedly installed on the outside of one side of the solid waste pollution treatment box 1 between the air inlet pipe 6 and the partition 2, and an electric heating wire is arranged around the inside of the air duct 34. The solid particle filter cloth belt 5 is located on the outside of the solid waste pollution treatment box 1 away from the air inlet pipe 6 and is provided with an exhaust pipe 35. The input end of the exhaust pipe 35 is conductively connected to the output end of the air duct 34, and the output end of the exhaust pipe 35 is fixedly installed on the outside of one side of the solid waste pollution treatment box 1.

[0050] Specifically, by penetrating the discharge pipe 35 and the solid particle filter cloth belt 5, the discharge pipe 35 can guide the hot air to both sides of the solid particle filter cloth belt 5 when blowing and drying the cleaned solid particle filter cloth belt 5, so that the surfaces on both sides of the solid particle filter cloth belt 5 can be dried by the hot air, and the overall drying efficiency is higher.

[0051] On both sides of the solid waste pollution treatment box 1 close to the two pressure rollers 32, fixing plates 30 are horizontally and fixedly installed. On the sides of the fixing plates 30 close to the pressure rollers 32, sliders 31 are symmetrically and longitudinally slidably engaged. Both ends of the pressure rollers 32 penetrate and are rotatably installed inside the sliders 31 on the corresponding sides. A resisting spring 33 is fixedly connected between one side of the slider 31 and one side of the fixing plate 30.

[0052] In this embodiment, when the solid particle filter cloth belt 5 after scraping and cleaning runs to the top side of the spraying pipe 25 through the partition plate 2, with the start of the liquid supply pump 24, the existing disinfectant in the outside world is supplied into the spraying pipe 25. Then, the disinfectant is sprayed onto the surface of the solid particle filter cloth belt 5 after cleaning through the spraying pipe 25 for surface disinfection. At the same time, when the second driving roller 4 rotates, it will drive the arc-shaped convex blocks 26 on both sides to rotate synchronously. Through the setting of the arc-shaped surface of the arc-shaped convex block 26, after the arc-shaped convex block 26 rotates a certain angle, it will contact one side of the rotating frame 27, so that the rotating frame 27 drives the rotating rod 28 to rotate, making the knocking block 29 fixed on one side of the rotating frame 27 tilt up. When the arc-shaped convex block 26 continues to rotate a certain angle, at this time, the arc-shaped convex block 26 no longer contacts the rotating frame 27. At this time, due to the action of gravity, the knocking block 29 quickly falls back and knocks on the surface of the solid particle filter cloth belt 5. This operation is repeated, so that through the intermittent knocking and vibration of the knocking block 29, the solid particle filter cloth belt 5 vibrates at a high frequency during spraying, enabling the disinfectant to better penetrate into the fiber gaps inside the solid particle filter cloth belt 5, solving the defect that traditional static spraying only acts on the surface, especially improving the deep disinfection effect of the wet solid particle filter cloth belt 5. The solid particle filter cloth belt 5 after spraying and disinfection is conveyed between the two pressure rollers 32. At this time, through the longitudinal sliding setting of the slider 31 and the extrusion and resistance of the resisting spring 33, the solid particle filter cloth belt 5 passing between the two pressure rollers 32 will be squeezed, thereby discharging the bacteria-containing sewage inside the solid particle filter cloth belt 5 and restoring part of the air permeability of the solid particle filter cloth belt 5. Then, combined with the heating of the heating wire inside the air guide pipe 34 and the conduction of the discharge pipe 35, the filtered and heated gas is blown onto the surface of the solid particle filter cloth belt 5 after disinfection and extrusion for drying, so that it can be recycled and its filtering treatment effect is ensured.

[0053] The present invention also provides a method for an air solid waste pollution filtering device used in a pulp production workshop, including the following steps:

[0054] S1: During use, first, the rotation of the output shaft of the driving motor 8 drives the driving gear 7 and one of the first transmission rollers 3 to rotate, thereby driving the switching of the solid particle filter cloth belt 5 sleeved on the outer surfaces of the first transmission roller 3 and the second transmission roller 4. In this way, the solid particle filter cloth belt 5 at the output end of the air inlet pipe 6 is replaced in a timely manner, and the solid particle filter cloth belt 5 with adhered fiber particles is conveyed to the top of the cleaning and compressing mechanism;

[0055] S2: Through the operation of the cleaning and compressing mechanism, the fiber particle impurities on the surface of the solid particle filter cloth belt 5 are mechanically peeled off;

[0056] S3: When the solid particle filter cloth belt 5 is being switched and cleaned, it can trigger the synchronous operation of the extrusion and sterilization mechanism, so that the bactericide can be sprayed onto the surface of the cleaned solid particle filter cloth belt 5, and then cooperate with the pressing roller 32 to extrude, so as to discharge the bacteria-containing sewage inside the solid particle filter cloth belt 5;

[0057] S4: Then, combined with the conduction of the air guide pipe 34 and the discharge pipe 35, the filtered and heated gas is blown onto the surface of the disinfected and extruded solid particle filter cloth belt 5 to dry it;
