Description

Technical Field

[0001] The utility model relates to the technical field of synthetic waste gas treatment, in particular to a waste gas absorption and ventilation device for PHMB synthesis. Background Art

[0002] PHMB is a polymer, the full name is polyhexamethylene di-glycidyl ammonium chloride, it is a broad-spectrum antibacterial agent with a broad-spectrum bactericidal power, especially for some Gram-negative bacteria that are difficult to treat with other bactericides. PMHB is synthesized from a variety of substances, so the synthesis process will inevitably produce certain waste gas. If these waste gases are directly discharged, it will cause air pollution, etc.

[0003] When treating PHMB synthetic waste gas, the conventional treatment method is to directly introduce the gas into the reaction container and react it with the chemical solution, thereby removing the harmful substances and then discharging it. However, the initial waste gas often carries a variety of impurity particles. The presence of these impurity particles not only affects the subsequent reaction rate with the solution, but also easily causes the gas introduction channel to be blocked, thereby reducing the gas purification efficiency.

[0004] In view of the technical defects in this aspect, a solution is now proposed. Utility Model Content

[0005] The purpose of the utility model is to achieve self-cleaning of the filter components while initially filtering impurities such as particulate matter in the exhaust gas by setting an absorption frame, an air supply frame, a filter cartridge and a lifting mechanism, thereby achieving a pre-purification effect on the gas to avoid increasing the time of subsequent reaction processing and improving the gas purification efficiency.

[0006] The purpose of the utility model can be achieved through the following technical solutions: a waste gas absorption ventilation device for PHMB synthesis, comprising an air supply frame and an absorption frame, the absorption frame is installed by a bracket, and the air supply frame is movably installed at the bottom of the absorption frame, an air inlet pipe is arranged at the center of the bottom surface of the air supply frame, and exhaust pipes are arranged at both ends of the top surface of the air supply frame, a rectangular through groove is arranged at the upper end of the absorption frame, and a rectangular inner groove is arranged at the middle and lower ends inside the absorption frame, the bottom end of the inner groove is connected to a bottom plate, and filter cartridges are rotatably arranged at both ends of the top surface of the bottom plate, the bottom of the filter cartridge is open and connected to the exhaust pipe, the top end of the filter cartridge extends to the inside of a limiting circular groove opened on the inner wall of the top of the inner groove, and a scraper cylinder is arranged on the inner wall of the limiting circular groove, and ventilation pipes are arranged at the center of the inner walls on both sides of the inner groove.

[0007] Furthermore, a rotating drum is rotatably connected at the center of the base plate, and the bottom of the rotating drum extends to the outside of the absorption frame and is fixedly connected to the top surface of the air supply frame. A vertical groove is provided at the bottom end of the inner wall of the front end of the rotating drum, and an annular groove is provided at the upper end of the vertical groove on the inner wall of the rotating drum, and the annular groove is communicated with the vertical groove.

[0008] Furthermore, the inner walls on both sides of the through slot are provided with sliding grooves, and a lifting mechanism is arranged inside the through slot, and the lifting mechanism includes a cylinder, which is arranged at the center of the inner wall at the top of the through slot, and a push rod is arranged at the bottom of the cylinder, and a movable plate is fixedly installed at the bottom of the push rod.

[0009] Furthermore, the movable plate is slidably connected to the bottom end of the two sets of slide grooves, and the two ends of the movable plate are rotatably connected with spiral rods, the upper and lower ends of the spiral rods extend to the upper and lower ends of the movable plate respectively, and the bottom of the spiral rod is fixedly connected to the corresponding top surface of the filter cartridge.

[0010] Furthermore, the lifting mechanism also includes a fixed plate, which is fixedly installed between the two groups of sliding grooves and located at the upper end of the movable plate, and spiral grooves are respectively provided at both ends of the fixed plate corresponding to the spiral rods.

[0011] Furthermore, a lifting rod is fixedly installed at the center of the bottom end of the movable plate, and the bottom of the lifting rod passes through the inner groove and is inserted into the inside of the rotating drum.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model provides an air supply frame, an absorption frame, a rotating drum, a scraper drum and a lifting mechanism. The air supply frame is used to send the gas into the absorption frame and align the two groups of filter cartridges in a straight line. The introduced gas is filtered by the mesh plates of the two groups of filter cartridges. The cylinder drives the movable plate, the spiral rod and the filter cartridge to move upward. The two groups of filter cartridges are inserted into the corresponding limiting circular grooves and scraped against the inner wall of the scraper drum, so that the filter cartridge mesh surface is cleaned. The spiral rod rises and is inserted into the corresponding spiral groove, forcing the spiral rod and the filter cartridge to fully rotate, thereby accelerating the cleaning efficiency of the filter cartridge mesh surface. This structure can not only assist in filtering and removing particulate matter in the exhaust gas to achieve preliminary purification of the gas, but also achieve self-cleaning of the filter components, thereby improving the continuous purification efficiency of the gas.

[0014] 2. The utility model uses a rotating drum and a lifting rod, which are used in conjunction with a lifting mechanism and an air supply frame. The lifting rod and the circular axis are pulled upward by a movable plate, and the lifting rod and the rotating drum move relative to each other. The rotating drum and the air supply frame rotate, causing the air supply frame to rotate, forcing the exhaust pipe to move away from the bottom end of the suction filter cartridge, which not only facilitates the discharge of all impurity particles in the filter cartridge, but also reduces the accumulation of discharged impurity particles in the exhaust pipe to increase the pollution of the subsequent introduced gas.

DETAILED DESCRIPTION

[0022] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1:

[0024] See also Figure 1 - Figure 5As shown, a waste gas absorption ventilation device for PHMB synthesis includes an air supply frame 1 and an absorption frame 2, the absorption frame 2 is installed by a bracket, and the air supply frame 1 is movably installed at the bottom of the absorption frame 2, an air inlet pipe 3 is arranged at the center of the bottom surface of the air supply frame 1, and exhaust pipes 4 are arranged at both ends of the top surface of the air supply frame 1, a rectangular through groove 5 is arranged at the upper end of the absorption frame 2, and a rectangular inner groove 6 is arranged at the middle and lower end of the absorption frame 2, the bottom end of the inner groove 6 is connected to a bottom plate 7, and the top surface of the bottom plate 7 is rotatably provided with filter cartridges 8 at both ends, and the bottom of the filter cartridge 8 is open and faces the exhaust pipe 4 The top of the filter cartridge 8 extends to the inside of the limiting circular groove 9 opened on the inner wall of the top of the inner tank 6, and a scraper 10 is arranged on the inner wall of the limiting circular groove 9. Ventilation pipes 11 are arranged at the center of the inner walls on both sides of the inner tank 6. The exhaust gas is first introduced into the air supply frame 1 through the air inlet pipe 3 frame, and then the gas is sent into the docking filter cartridge 8 by the two sets of exhaust pipes 4. In the process of the gas rising upward, the mesh of the filter cartridge 8 blocks the impurity particles of the gas, and the filtered gas passes through the mesh and enters the absorption frame 2. Finally, the two sets of ventilation pipes 11 introduce the gas into the external reaction tank for further purification.

[0025] Slide grooves 501 are provided on the inner walls on both sides of the through groove 5, and a lifting mechanism 12 is provided inside the through groove 5. The lifting mechanism 12 includes a cylinder 121, which is arranged at the center of the inner wall at the top of the through groove 5, and a push rod 122 is provided at the bottom of the cylinder 121, and a movable plate 123 is fixedly installed at the bottom of the push rod 122. The movable plate 123 is slidably connected to the bottom end position inside the two groups of slide grooves 501, and the two ends of the movable plate 123 are rotatably connected with spiral rods 124 respectively, and the upper and lower ends of the spiral rod 124 extend to the upper and lower ends of the movable plate 123 respectively, and the bottom of the spiral rod 124 is fixedly connected to the corresponding top surface of the filter cartridge 8. The lifting mechanism 12 also includes a fixed plate 125, which is fixedly installed between the two groups of slide grooves 501 and located at the upper end of the movable plate 123, and spiral grooves 126 are provided at the two ends of the fixed plate 125 corresponding to the spiral rod 124.

[0026] After the filter cartridge 8 has undergone multiple filtering operations, the cylinder 121 is started, which uses the push rod 122 to pull the movable plate 123, the spiral rod 124, the filter cartridge 8 and the bottom plate 7 upward, and the two groups of filter cartridges 8 pass through the interior of the limiting circular groove 9 in turn, and rub against the inner wall of the scraper cylinder 10, so as to facilitate the cleaning of the particles on the mesh surface of the filter cartridge 8 and reduce the blockage of the mesh of the filter cartridge 8. At the same time, the two groups of spiral rods 124 pass through the interior of the spiral groove 126 upward respectively. Since the spiral rod 124 is adapted to the inner wall of the spiral groove 126, the spiral rod 124 and the filter cartridge 8 can continuously rotate, thereby enhancing the friction effect between the filter cartridge 8 and the inner wall of the scraper cylinder 10, accelerating the cleaning rate of the filter cartridge 8, keeping the mesh unobstructed and facilitating continuous filtration. After cleaning, the cylinder 121 drives the push rod 122 downward, and the movable plate 123, the spiral rod 124 and the filter cartridge 8 all sink downward for subsequent gas filtration.

[0027] Embodiment 2:

[0028] See also Figure 2 and Figure 5 As shown, a rotating drum 701 is rotatably connected at the center of the bottom plate 7, and the bottom of the rotating drum 701 extends to the outside of the absorption frame 2 and is fixedly connected to the top surface of the air supply frame 1. A vertical groove 702 is provided at the bottom of the inner wall of the front end of the rotating drum 701, and an annular groove 703 is provided at the upper end of the vertical groove 702 on the inner wall of the rotating drum 701, and the annular groove 703 is connected to the vertical groove 702;

[0029] A lifting rod 127 is fixedly installed at the center of the bottom end of the movable plate 123, and the bottom of the lifting rod 127 passes through the inner groove 6 and is inserted into the inside of the rotating drum 701. The front end surface of the lifting rod 127 is located at the bottom and a round shaft 128 is fixedly installed, and the round shaft 128 is slidably connected to the inside of the vertical groove 702; as the cylinder 121 pulls the movable plate 123 upward, and the lifting rod 127 moves upward along the inside of the rotating drum 701, the round shaft 128 initially moves linearly upward along the inside of the vertical groove 702, and then the round shaft 128 slides to the annular groove 703 and continues to move upward. The inner wall of 703 forces the rotating drum 701 and the absorption frame 2 to rotate. At this time, the two groups of exhaust pipes 4 gradually move away from the bottom of the filter cartridge 8, which not only reduces the dust falling into the air supply frame 1 when the filter cartridge 8 is cleaned and causes the gas pollution to increase, but also facilitates the direct discharge of partially filtered impurities; after cleaning, the lifting rod 127 is reinserted into the rotating drum 701, and the circular shaft 128 sinks downward and moves along the annular groove 703 first, forcing the rotating drum 701 and the air supply frame 1 to rotate in the opposite direction, forcing the two groups of exhaust pipes 4 to be aligned with the bottom of the filter cartridge 8 again.

[0030] Working principle: When the utility model is in use, the exhaust gas is first introduced into the air supply frame 1 through the air inlet pipe 3, and then the gas is sent into the docking filter cartridge 8 by two sets of exhaust pipes 4. During the upward rise of the gas, the gas filtered by the mesh of the filter cartridge 8 passes through the mesh and enters the absorption frame 2. Finally, the filtered gas is introduced into the external reaction tank by two sets of ventilation pipes 11 for further purification.

[0031] Then start the cylinder 121, which uses the push rod 122 to pull the movable plate 123, the spiral rod 124 and the filter cartridge 8 upward. The two groups of filter cartridges 8 successively penetrate the interior of the limiting circular groove 9 and rub against the inner wall of the scraper 10, which is convenient for cleaning the particles on the mesh surface of the filter cartridge 8 and reducing the clogging of the mesh of the filter cartridge 8. At the same time, the two groups of spiral rods 124 respectively penetrate into the interior of the spiral groove 126 upward. Since the spiral rod 124 is adapted to the inner wall of the spiral groove 126, the spiral rod 124 and the filter cartridge 8 are continuously rotated, thereby enhancing the friction effect between the filter cartridge 8 and the inner wall of the scraper 10.

[0032] At the same time, the movable plate 123 moves upward, and the lifting rod 127 moves upward along the inside of the rotating drum 701. At first, the circular shaft 128 moves upward along the inside of the vertical groove 702 in a straight line, and then the circular shaft 128 slides to the annular groove 703 and continues to move upward. Because the circular shaft 128 presses against the inner wall of the annular groove 703, the rotating drum 701 and the absorption frame 2 are forced to rotate. At this time, the two sets of exhaust pipes 4 gradually move away from the bottom of the filter cartridge 8, reducing the dust falling into the air supply frame 1 when the filter cartridge 8 is cleaned, which causes the gas pollution to increase.

[0033] After cleaning, the cylinder 121 drives the push rod 122 downward, and the movable plate 123, the spiral rod 124 and the filter cartridge 8 all sink downward to facilitate subsequent gas filtration; at the same time, the lifting rod 127 is reinserted into the drum 701, and the circular shaft 128 sinks downward and first moves along the inside of the annular groove 703, forcing the drum 701 and the air supply frame 1 to rotate in the opposite direction, forcing the two sets of exhaust pipes 4 to be aligned with the bottom of the filter cartridge 8 again.

Obviously, many modifications and changes can be made according to the content of this specification.
