Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment devices, and in particular to a tubular membrane defluorination device for industrial wastewater. Background Art

[0002] Fluorine is highly corrosive and toxic. Given the high harmfulness of fluorine, if the fluorine content in industrial wastewater is too high, it will cause great pollution to the environment. Therefore, defluorination treatment is required when industrial wastewater is discharged to prevent wastewater from polluting the environment. When removing fluorine from industrial wastewater, a dedicated industrial wastewater defluorination processor is required.

[0003] For example, the utility model patent with publication number CN220098595U discloses a tubular membrane defluorination treatment device for industrial wastewater, which is equipped with a rotary scraping mechanism that utilizes the sewage circulation and conveying pressure to drive and clean the impurities intercepted on the defluorination membrane and the impurities generated by the reaction. However, this rotary scraping mechanism lacks a brake mechanism that can position its rotational motion when it is not necessary to use and is idle. As a result, during the wastewater treatment process, the rotary scraping mechanism continues to rotate for a long time without interruption, which easily causes excessive wear to the defluorination membrane, causing the defluorination membrane to fail to reach its standard design service life, indirectly increasing the number of replacements and consumption of the defluorination membrane; In addition, although some rotary scraping mechanisms are equipped with brake mechanisms, the optimization design of the tension and relaxation drive structure of the brake mechanism is not reasonable enough, and most of them are slidably assembled with sewage pipes (channels), which affects the sealing of the processor and requires additional sliding sealing, which indirectly increases the difficulty and cost of processor manufacturing. Summary of the invention

[0004] In view of this, the present invention provides a tubular membrane defluorination treatment device for industrial wastewater to solve the problem that the optimization design of the tension and relaxation driving structure of the brake mechanism is not reasonable, and it is often slidably assembled with the sewage pipe (channel), which affects the sealing of the treatment device and requires additional sliding sealing, which indirectly increases the difficulty and cost of manufacturing the treatment device.

[0005] The technical solution proposed by the present invention is: a tubular membrane defluorination treatment device for industrial wastewater, specifically comprising an outlet pipe, an inlet pipe and a treatment pipe; the bottom of the outlet pipe is welded with an inlet pipe, and the top of the inlet pipe is welded and hoisted with a treatment pipe connected to the outlet pipe; A mounting frame is welded around the inner side of the circumferential side wall of the treatment tube, and a fluorine removal film is provided on one end of the mounting frame facing the inner side of the treatment tube; A water wheel is rotatably installed at the bottom of the water outlet pipe, an L-shaped driving rod is hoisted and fixed at the bottom end of the water wheel, a rubber scraper is fixed on the vertical support part of the L-shaped driving rod, and the rubber scraper follows the rotation of the water wheel to scrape and contact the defluorination film to perform cleaning; An impurity discharge pipe is welded to the center position below the bottom of the processing tube, and a plug cover is threadedly fixed to the bottom opening of the impurity discharge pipe; a hexagonal force transmission rod is slidably installed through the center of the plug cover, and a brake disc is welded to the top of the hexagonal force transmission rod; a push bolt is screwed and installed through the bottom position of the circumferential side wall of the processing tube, and a push rod is swingably suspended at the bottom of the circumferential side wall of the processing tube; when the push bolt is screwed downward, the push rod swings upward to push and drive the hexagonal force transmission rod to slide upward to apply pressure to the L-shaped drive rod for braking.

[0006] Furthermore, A limit ring is welded onto the portion of the hexagonal force transmission rod close to the plug cover, and when the hexagonal force transmission rod slides downward, the limit ring comes into contact with the plug cover; A horizontally arranged brake disc is welded to the top of the hexagonal force transmission rod, and a rubber pad is fixed to the top of the brake disc. When the hexagonal force transmission rod slides upward, the brake disc is pressed against the bottom end of the vertical support part of the L-shaped driving rod.

[0007] Furthermore, A U-shaped hanging block is welded and installed at the bottom of the processing tube near the push bolt, and the push rod is rotatably hinged with the U-shaped hanging block; The bottom end of the push bolt abuts against the tail end of the push rod, and the top end of the push rod swings upward and abuts against the bottom end of the hexagonal force transmission rod.

[0008] Furthermore, A sleeve frame is slidably installed around and through the circumferential side wall of the processing tube at the position of the installation frame, and an L-shaped positioning rod is welded to the middle position of the bottom of the sleeve frame. The L-shaped positioning rod is pushed by a spring and slides through the circumferential side wall of the processing tube.

[0009] Furthermore, An arc-shaped force-bearing plate is welded to one end of the L-shaped positioning rod facing the inner side of the processing tube, and the head end of the horizontal part of the L-shaped driving rod follows the rotation of the water wheel and sequentially abuts against the arc-shaped force-bearing plate; A guide wheel is rotatably mounted on the head end of the horizontal part of the L-shaped driving rod.

[0010] Furthermore, An installation frame which is suitable for the shape of the sleeve frame is welded on one end of the sleeve frame which is far away from the inner side of the processing tube, and the sleeve frame and the installation frame are slidably inserted and matched.

[0011] Furthermore, A material collecting cover is welded at the bottom of the water outlet pipe, and the top end of the impurity discharge pipe is welded and communicated with the material collecting cover.

[0012] Furthermore, The impurity discharge pipe and the hexagonal force transmission rod are both arranged vertically, and the hexagonal force transmission rod is interlaced and matched with the impurity discharge pipe and the aggregate cover.

[0013] Furthermore, A flange is welded on the top end of the water inlet pipe, and the water inlet pipe is connected to the front process of industrial wastewater treatment.

[0014] The tubular membrane defluorination processor for industrial wastewater provided by the present invention has the following beneficial effects: According to the present invention, when the hexagonal force transmission rod slides upward, the brake disc and the bottom end of the vertical support part of the L-shaped driving rod are pressed against each other, and the L-shaped driving rod and the water wheel can be braked, so that the L-shaped driving rod can be stopped and kept relatively still with the defluorination membrane in an idle state when it is not necessary to use. Compared with the prior art that lacks a brake mechanism, it can avoid the excessive wear of the defluorination membrane caused by the long-term uninterrupted rotation operation of the rotating scraping mechanism during the wastewater treatment process, resulting in the defluorination membrane failing to reach its standard design service life, which helps to indirectly reduce the replacement frequency and consumption of the defluorination membrane and reduce the operation and maintenance costs of the processor.

[0015] In addition, the rod and the push bolt serve as a mechanism for driving the tightening and loosening brake of the hexagonal force transmission rod, and are exposed at the bottom of the processing tube and the outer side of the circumference of the bottom, and are not slidably assembled with the processing tube at all. Compared with the existing technology in which the tightening and loosening driving structure of the brake mechanism is set to be slidably assembled with the processor housing, the sealing of the processor can be ensured without additional consideration of the sliding sealing problem, which helps to indirectly reduce the difficulty and cost of the processor manufacturing process.

[0016] In addition, through the arc-shaped force-bearing plate's arc-shaped guiding principle and in conjunction with the spring on the L-shaped positioning rod, the L-shaped driving rod can push and drive a circle of frames to slide inward and outward in sequence as it rotates with the water wheel, impacting and vibrating the mounting frame and the defluorination film thereon, and assisting in the removal of impurities from the defluorination film for cleaning. This, when used in conjunction with the L-shaped driving rod, can implement a combined cleaning of the defluorination film by means of vibration and scraping, which is more thorough and comprehensive in cleaning impurities on the defluorination film, and has a better cleaning effect.

[0017] In addition, when the sleeve frame slides and vibrates inside and outside for cleaning, it reciprocates along the inside and outside of the installation frame without separating from the installation frame. The installation frame can cover and block the vacant space vacated when the sleeve frame and the installation frame slide relative to each other, thereby preventing sewage from leaking out of the vacant space without being treated, affecting the purity and effect of the processor on sewage treatment.

[0021] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0022] Please refer to Figures 1 to 8 ; Example

[0023] The present invention provides a tubular membrane defluorination treatment device for industrial wastewater, comprising an outlet pipe 1, a push bolt 101, a push rod 102, a U-shaped hanging block 103, an inlet pipe 2, a treatment pipe 3, an impurity discharge pipe 301, a plugging cover 3011, a sleeve frame 302, a mounting frame 3021, an L-shaped positioning rod 3022, an arc-shaped force plate 3023, a connecting frame 3024, a hexagonal force transmission rod 303, a water wheel 4, an L-shaped driving rod 401, and a rubber scraper 4011; the bottom of the outlet pipe 1 is welded with the inlet pipe 2, and the top of the inner part of the inlet pipe 2 is welded and hoisted with the treatment pipe 3 connected with the outlet pipe 1; A mounting frame 3021 is welded around the inner side of the circumferential side wall of the processing tube 3, and a fluorine removal film is provided on one end of the mounting frame 3021 facing the inner side of the processing tube 3; A water wheel 4 is rotatably installed at the bottom side of the outlet pipe 1. The water wheel 4 is driven to rotate by the sewage flowing inside the outlet pipe 1. An L-shaped driving rod 401 is hoisted and fixed at the bottom end of the water wheel 4. A rubber scraper 4011 is fixed on the vertical support part of the L-shaped driving rod 401. The rubber scraper 4011 rotates with the water wheel 4 and scrapes and contacts the defluorination membrane to clean the impurities intercepted on the defluorination membrane and the impurities generated by the reaction. The cleaned impurities are deposited in the impurity discharge pipe 301 for temporary storage. An impurity discharge pipe 301 is welded to the bottom center of the processing pipe 3, and a plug cover 3011 is threadedly fixed to the bottom opening of the impurity discharge pipe 301; a hexagonal force transmission rod 303 is slidably installed through the center of the plug cover 3011, and a brake disc is welded to the top of the hexagonal force transmission rod 303; a push bolt 101 is screwed and installed through the bottom position of the circumferential side wall of the processing pipe 3, and a push rod 102 is swingably hoisted at the bottom of the circumferential side wall of the processing pipe 3; Preferably, A limit ring is welded on the portion of the hexagonal force transmission rod 303 close to the blocking cover 3011. When the hexagonal force transmission rod 303 slides downward, the limit ring abuts against the blocking cover 3011. A horizontally arranged brake disc is welded to the top of the hexagonal force transmission rod 303, and a rubber pad is fixed to the top of the brake disc. When the hexagonal force transmission rod 303 slides upward, the brake disc presses against the bottom end of the vertical support part of the L-shaped driving rod 401, and can apply top pressure braking to the L-shaped driving rod 401 and the water wheel 4, so that the L-shaped driving rod 401 can be stopped when it is not necessary to use and can remain relatively still with the defluorination membrane in an idle state. Compared with the existing technology that lacks a brake mechanism, it can avoid the long-term uninterrupted rotation of the rotating scraping mechanism during the wastewater treatment process, which causes excessive wear on the defluorination membrane and causes the defluorination membrane to fail to reach its standard design service life, which helps to indirectly reduce the replacement frequency and consumption of the defluorination membrane and reduce the operation and maintenance costs of the processor.

[0024] Preferably, A U-shaped hanging block 103 is welded and installed at the bottom of the processing tube 3 near the push bolt 101, and the push rod 102 is rotatably hinged with the U-shaped hanging block 103; The bottom end of the push bolt 101 is in contact with the tail end of the push rod 102, and the top end of the push rod 102 that swings upward is in contact with the bottom end of the hexagonal force transmission rod 303. When the push rod 102 is screwed downward, it can push and drive the push rod 102 to swing upward, control the hexagonal force transmission rod 303 to slide upward, and provide a driving force for the L-shaped driving rod 401 to press the brake. When the push rod 102 is screwed upward, the push rod 102 loses its upward pushing holding force. The push rod 102 can swing downward by gravity to disengage from the hexagonal force transmission rod 303. After the push rod 102 is disengaged from the hexagonal force transmission rod 303, the hexagonal force transmission rod 303 slides down by gravity of its body to release the L-shaped driving rod 401. After the push rod 102 is disengaged from the hexagonal force transmission rod 303, it can continue to swing downward to vacate the bottom space of the impurity discharge pipe 301, so that the plugging cover 3011 can be disassembled to dump and clean the impurities accumulated inside the impurity discharge pipe 301. The push rod 102 and the push bolt 101 serve as a mechanism for driving the tightening and loosening of the hexagonal force transmission rod 303. They are exposed at the bottom of the processing tube 3 and the outer side of the circumference of the bottom, and are not slidably assembled with the processing tube 3 at all. Compared with the existing technology in which the tightening and loosening driving structure of the brake mechanism is set to be slidably assembled with the processor housing, the sealing of the processor can be ensured without additional consideration of the sliding sealing problem, which helps to indirectly reduce the difficulty and cost of the processor manufacturing process.

[0025] Preferably, A circle of frame 302 is slidably installed around the installation frame 3021 on the circumferential side wall of the processing tube 3, and an L-shaped positioning rod 3022 is welded to the middle position of the bottom of the frame 302. The L-shaped positioning rod 3022 is pushed by a spring to slide through the circumferential side wall of the processing tube 3.

[0026] Preferably, An arc-shaped force-bearing plate 3023 is welded to one end of the L-shaped positioning rod 3022 facing the inner side of the processing tube 3. The head end of the horizontal part of the L-shaped driving rod 401 follows the rotation of the water wheel 4 and contacts the arc-shaped force-bearing plate 3023 in turn. Through the arc surface guiding principle of the arc-shaped force-bearing plate 3023 and in conjunction with the spring on the L-shaped positioning rod 3022, the L-shaped driving rod 401 can push and drive a circle of the frame 302 to slide inward and outward in turn when following the rotation of the water wheel 4, impacting and vibrating the installation frame 3021 and the defluorination film thereon, and assisting in the falling cleaning of impurities on the defluorination film. This, when used together with the L-shaped driving rod 401, can implement a composite cleaning of the defluorination film by means of vibration and scraping, and the cleaning of impurities on the defluorination film is more thorough and comprehensive, with better cleaning effect. Through the water wheel 4, the L-shaped driving rod 401 can be driven to rotate indirectly by the circulating pressure of the sewage, which saves the need to configure an additional driving motor for the rotating scraping action and the vibration cleaning action of the defluorination membrane, and helps to reduce the overall cost and energy consumption of the processor; A guide wheel is rotatably mounted on the head end of the horizontal portion of the L-shaped driving rod 401 .

[0027] Preferably, A polymer cover is welded to the bottom of the water outlet pipe 1, and the top end of the impurity discharge pipe 301 is welded and connected to the polymer cover.

[0028] Preferably, The impurity discharge pipe 301 and the hexagonal force transmission rod 303 are both arranged vertically, and the hexagonal force transmission rod 303 is interlaced and matched with the impurity discharge pipe 301 and the aggregate cover.

[0029] Preferably, A flange is welded to the top of the water inlet pipe 2, and the water inlet pipe 2 is connected to the previous process of industrial wastewater treatment.

[0030] Based on the first embodiment, the second embodiment: An installation frame 3021 that matches the shape of the sleeve frame 302 is welded on one end of the sleeve frame 302 away from the inner side of the treatment tube 3. The sleeve frame 302 and the installation frame 3021 are slidably inserted into each other. When the sleeve frame 302 slides in and out for vibration cleaning, it reciprocates along the installation frame 3021 and does not separate from the installation frame 3021. The installation frame 3021 can cover and block the vacant space vacated when the sleeve frame 302 and the installation frame 3021 slide relative to each other, so as to prevent sewage from leaking out of the vacant space without treatment, thereby affecting the purity and effect of the processor on sewage treatment.

[0031] When in use, the sewage enters the treatment pipe 3 through the water inlet pipe 2, and then under the water delivery load, the sewage passes through a circle of fluorine removal membrane and a circle of casing 302, and is pressed into the annular space between the water outlet pipe 1 and the treatment pipe 3 for discharge, and most of the fluorine elements impregnated in the sewage are removed when passing through the fluorine removal membrane; The water wheel 4 is driven to rotate by the sewage flowing in the outlet pipe 1. A rubber scraper 4011 is fixed on the vertical support part of the L-shaped driving rod 401. The rubber scraper 4011 follows the rotation of the water wheel 4 and scrapes and contacts the defluorination membrane to clean the impurities intercepted on the defluorination membrane and the impurities generated by the reaction. The cleaned impurities are deposited in the impurity discharge pipe 301 for temporary storage. When the hexagonal force transmission rod 303 slides upward, the brake disc and the bottom end of the vertical support part of the L-shaped driving rod 401 are pressed against each other, and the L-shaped driving rod 401 and the water wheel 4 can be braked, so that the L-shaped driving rod 401 can be stopped and kept relatively still with the defluorination membrane in an idle state when it is not necessary to use, so as to avoid excessive wear of the defluorination membrane during the wastewater treatment process. When the top rod 102 is screwed downward, the top rod 102 can be pushed to drive the top rod 102 to swing upward, and the hexagonal force transmission rod 303 can be controlled to slide upward, providing the driving force for the L-shaped driving rod 401 to press the brake. When the top rod 102 is screwed upward, the top rod 102 loses the upward pushing holding force and can swing downward by its gravity to separate from the hexagonal force transmission rod 303. After the top rod 102 is separated from the hexagonal force transmission rod 303, the hexagonal force transmission rod 303 slides down by the gravity of its body to release the L-shaped driving rod 401. After the top rod 102 is disengaged from the hexagonal force transmission rod 303, it continues to swing downward to vacate the space below the bottom of the impurity discharge pipe 301, so that the plugging cover 3011 can be disassembled to dump and clean the impurities accumulated inside the impurity discharge pipe 301; Through the arc surface guiding principle of the arc force plate 3023 and in conjunction with the spring on the L-shaped positioning rod 3022, the L-shaped driving rod 401 can push and drive a circle of frames 302 to slide inwards and outwards in sequence when rotating with the water wheel 4, impacting and vibrating the mounting frame 3021 and the defluorination film thereon, and assisting in the removal of impurities on the defluorination film by dropping and cleaning. This, when used together with the L-shaped driving rod 401, can implement a combined cleaning of the defluorination film by both vibration and scraping.
