Description

Technical Field

[0001] The present invention belongs to the technical field of impurity removal for bromination reaction products, and specifically relates to a washing device for removing impurities from bromination reaction products. Background Art

[0002] In bromination reaction products, a large amount of impurities may be generated during the reaction process. These impurities may cause blockage of the filtration device and affect the efficiency of the entire process. Therefore, using an automatic backwash filter can effectively remove these impurities and keep the system running normally. An automatic backwash filter is a device that can automatically remove the impurities accumulated inside the filter through a reverse flow cleaning method. During the operation of the filter, impurities will gradually accumulate, but when the impurities accumulate to a certain extent, the device will automatically start the backwash process.

[0003] In the prior art during the backwash process, the liquid flow direction is usually reversed, which can effectively remove the deposits on the filter without manual intervention. Since during backwashing, one side of the filter screen is rinsed, it may cause the impurity particles to be pushed to the other side of the filter screen, resulting in the re-accumulation of impurity particles and reducing the working efficiency of the automatic backwash filter for removing impurities from bromination reaction products. Summary of the Invention

[0004] To solve the problem of poor filtration effect proposed in the above background art, during backwash single-direction impact, only one side of the filter screen is rinsed, resulting in impurity particles adhering to the other side of the filter screen and affecting the cleaning effect of the impurity particles. The present invention provides a washing device for removing impurities from bromination reaction products.

[0005] To achieve the above object, the present invention provides the following technical solution: A washing device for removing impurities from bromination reaction products, including a backwash shell, the bottom end of the backwash shell is fixedly connected with a footrest, the top of the backwash shell is fixedly connected with a top cover, one side of the outer wall of the backwash shell is communicated with a water inlet pipe, the outer wall of the backwash shell far from the water inlet pipe is communicated with a drain pipe, and further includes a rotating protection component. The rotating protection component includes a fixed ring fixedly connected to the bottom end of the inner wall of the backwash shell, the inner wall of the fixed ring is fixedly connected with a filter rack net, and a waste discharge component is arranged on the top of the top cover to prevent impurity particles from getting stuck on the inner wall of the other side of the filter rack net during the backwash process. The waste discharge component includes a spiral rod in contact with the inner wall of the filter rack net to prevent impurity particles from adhering to the inner wall of the filter rack net.

[0006] Preferably, a motor is fixedly connected to the top of the top cover, the output end of the motor is fixedly connected with a rotating shaft, one end of the outer wall of the rotating shaft is fixedly connected to the inner wall of the spiral rod, a sealing plate is fixedly connected to the bottom of the rotating shaft, and a fixing plate is fixedly connected to the inner wall of the filter rack net.

[0007] Preferably, both sides of the bottom of the fixed plate are communicated with a double-headed pipe. One end of the double-headed pipe penetrates through the backwashing shell and extends to the outside of the backwashing shell. A sewage discharge valve is communicated with the outer wall of the end of the double-headed pipe away from the fixed plate.

[0008] Preferably, a backwashing assembly is arranged on the outer wall of the backwashing shell. The backwashing assembly includes a pressure gauge fixedly connected to the outer wall of the backwashing shell close to the drain pipe, and a bent pipe is communicated with the outer wall of the backwashing shell away from the pressure gauge.

[0009] Preferably, a circular sleeve is fixedly connected to the outer wall of one end of the rotating shaft close to the screw rod. Four bent rods are respectively fixedly connected to the outer wall of the circular sleeve. A rotating plate is fixedly connected to the end of the bent rod away from the circular sleeve. There is one rotating plate.

[0010] Preferably, the outer wall of the rotating plate is rotatably connected to the inner wall of the backwashing shell, the inner wall of the rotating plate is rotatably connected to the top outer wall of the filter rack net, and an annular shell is fixedly connected to the bottom of the rotating plate.

[0011] Preferably, a rotating ring is rotatably connected to the bottom of the annular shell. One end of the bent pipe penetrates through the rotating ring and extends into the annular shell. Four sprayers are respectively communicated with the inner wall of the annular shell. A plurality of spray holes are opened on one side of the sprayer.

[0012] Preferably, a protection assembly is arranged on the outer wall of the filter rack net. The protection assembly includes a plurality of telescopic rods fixedly connected to the outer wall of the filter rack net. Six telescopic rods are arranged in a group. A flexible ring is fixedly connected to the end of the telescopic rod away from the filter rack net. There are two flexible rings.

[0013] Preferably, a protection net is fixedly connected between the flexible rings. A plurality of round holes are opened on the outer wall of the protection net. A connecting plate is fixedly connected between the two groups of telescopic rods. A plurality of elastic impact rods are respectively slidably connected to one side of the outer wall of the connecting plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: Through the cooperation of the impurity removal component and the backwashing component, the bromination reaction liquid is poured into the interior of the backwashing shell through the water inlet pipe. The bromination reaction liquid flows through the filter rack net, causing impurity particles to stay on the inner wall of the filter rack net. The filtered bromination reaction liquid is discharged outward through the drain pipe, thereby obtaining the bromination reaction liquid with impurities removed. When the pressure at the inlet and the pressure at the outlet reach the set value, it can be observed through the pressure gauge, and the bromination reaction liquid is no longer injected. The backwashing water is injected into the interior of the annular shell through the elbow pipe. The backwashing water enters the interior of the water sprayer through the annular shell and is discharged outward through the water spray openings provided on the water sprayer, thereby performing backwashing work on the impurity particles adhering to the filter holes of the filter rack net. During the backwashing process, the impurity particles are washed off and stay on the outer wall of the screw rod, preventing the particles from adhering to the other side of the inner wall of the filter rack net due to the backwashing water flow. This can prevent the filter rack net from being contaminated and maintain a clean state for a long time.

[0015] Through the cooperation of the impurity removal component, the backwashing component, and the protection component, when the rotating shaft rotates, it drives the circular sleeve and the bent rod to rotate. The bent rod drives the rotating plate and the annular shell to rotate. The annular shell drives the water sprayer to rotate. The four water sprayers rotate and spray around the outer wall of the filter rack net, and the backwashing water can be evenly sprayed onto the entire surface of the filter rack net, effectively removing the impurity particles adhering to the grid. Rotating spraying can prevent the water flow from concentrating at a certain position and ensure that all parts of the filter rack net can be fully cleaned. When the backwashing water impacts the outer wall of the filter rack net, it will first contact the outer wall of the protection net, thereby reducing the impact force generated by the discharge of the backwashing water and preventing the impact force from being too large, causing damage to the filter rack net by the rotating screw rod.

[0016] Through the cooperation of the impurity removal component and the protection component, when the backwashing water impacts the protection net, the generated impact force causes the protection net and the flexible ring to undergo arc deformation. The flexible ring undergoes arc deformation when subjected to the impact force, and this deformation can play a buffering role, reducing the damage to other components caused by the direct impact force. When the flexible ring deforms, it will squeeze the telescopic rod. The movable end of the telescopic rod drives the connecting plate to move, and the connecting plate drives the elastic impact rod to move. During the movement of the elastic impact rod, it will impact the outer wall of the filter rack net, causing the filter rack net to vibrate, preventing the centrifugal force generated when the screw rod drives the impurity particles to descend from causing the impurity particles to adhere to the inner wall of the filter rack net again. The vibration breaks the adhesion force between the impurity particles and the surface of the filter rack net, ensuring the cleanliness of the surface of the filter rack net. Since the filter holes of the filter rack net are smaller than the round holes of the protection net, when there are overly small impurity particles moving to the outside of the filter rack net, they will not get stuck between the protection net and the filter rack net, which helps to maintain the smooth and efficient operation of the filtration system.

[0019] 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 in 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.

[0020] As Figures 1 to 9 shown, the present invention provides a washing device for removing impurities from bromination reaction products, including a backwashing shell 1. A leg frame 2 is fixedly connected to the bottom end of the backwashing shell 1. A top cover 3 is fixedly connected to the top of the backwashing shell 1. A water inlet pipe 4 is communicated with one side of the outer wall of the backwashing shell 1. A drain pipe 5 is communicated with the other side of the outer wall of the backwashing shell 1 away from the water inlet pipe 4. It further includes; Rotate the anti-washing protection assembly 6. The anti-washing protection assembly 6 includes a fixed ring 61 fixedly connected to the bottom end of the inner wall of the anti-washing shell 1. A filter rack net 62 is fixedly connected to the inner wall of the fixed ring 61. A waste discharging assembly 63 is arranged on the top of the top cover 3 to prevent impurity particles from getting stuck on the inner wall on the other side of the filter rack net 62 during the anti-washing process. The waste discharging assembly 63 includes a screw rod 633 in contact with the inner wall of the filter rack net 62 to prevent impurity particles from adhering to the inner wall of the filter rack net 62.

[0021] Adopt the above scheme: During the anti-washing process, the impurity particles are washed off and stay on the outer wall of the screw rod 633, preventing the particles from adhering to the inner wall on the other side of the filter rack net 62 again due to the reverse washing water flow. This can avoid the pollution of the filter rack net 62 and keep it clean for a long time.

[0022] A motor 631 is fixedly connected to the top of the top cover 3. The output end of the motor 631 is fixedly connected to a rotating shaft 632. One end of the outer wall of the rotating shaft 632 is fixedly connected to the inner wall of the screw rod 633. A sealing plate 634 is fixedly connected to the bottom of the rotating shaft 632. A fixing plate 635 is fixedly connected to the inner wall of the filter rack net 62.

[0023] Two one-way pipes 636 are communicated on both sides of the bottom of the fixing plate 635. One end of the one-way pipe 636 penetrates through the anti-washing shell 1 and extends to the outside of the anti-washing shell 1. A sewage discharge valve 637 is communicated with the outer wall of the one-way pipe 636 far away from the fixing plate 635.

[0024] Adopt the above scheme: The sealing plate 634 seals the one-way pipe 636 to prevent the bromination reaction liquid from flowing into the inside of the one-way pipe 636 during filtration. When the motor 631 is started, the sealing plate 634 rotates and no longer seals the one-way pipe 636, facilitating the discharge of impurity particles to the outside.

[0025] As Figures 1 to 9 As shown in the figure, an anti-washing assembly 64 is arranged on the outer wall of the anti-washing shell 1. The anti-washing assembly 64 includes a pressure gauge 641 fixedly connected to one side of the outer wall of the anti-washing shell 1 close to the outer wall of the drain pipe 5. A bent pipe 642 is communicated with the outer wall of the anti-washing shell 1 on the side far away from the pressure gauge 641.

[0026] Adopt the above scheme: The pressure gauge 641 can detect the pressure value at the inlet and the outlet, facilitating the staff to monitor the pressure value and facilitating the anti-washing work.

[0027] A circular sleeve 643 is fixedly connected to the outer wall of one end of the rotating shaft 632 close to the screw rod 633. Four bent rods 644 are respectively fixedly connected to the outer wall of the circular sleeve 643. One end of the bent rod 644 far away from the circular sleeve 643 is fixedly connected to a rotating plate 645. There is one rotating plate 645.

[0028] The outer wall of the rotating plate 645 is rotatably connected to the inner wall of the backwashing shell 1, and the inner wall of the rotating plate 645 is rotatably connected to the top outer wall of the filter rack net 62. The bottom of the rotating plate 645 is fixedly connected to an annular shell 646.

[0029] The bottom of the annular shell 646 is rotatably connected to a rotating ring 647. One end of the elbow pipe 642 passes through the rotating ring 647 and extends into the interior of the annular shell 646. The inner wall of the annular shell 646 is respectively communicated with four water sprayers 648, and a number of water spray openings are opened on one side of the water sprayer 648.

[0030] Adopting the above scheme: The rotating ring 647 rotates on the inner wall of the bottom of the annular shell 646, preventing the annular shell 646 from getting stuck with the fixed elbow pipe 642 when rotating, and improving the stability of the device operation.

[0031] A protection component 65 is arranged on the outer wall of the filter rack net 62. The protection component 65 includes a number of telescopic rods 651 fixedly connected to the outer wall of the filter rack net 62. Six telescopic rods 651 are arranged in a group. The end of the telescopic rod 651 far from the filter rack net 62 is fixedly connected to a flexible ring 652, and there are two flexible rings 652.

[0032] A protection net 653 is fixedly connected between the flexible rings 652. A number of round holes are opened on the outer wall of the protection net 653. A connecting plate 654 is fixedly connected between the two groups of telescopic rods 651, and a number of elastic impact rods 655 are respectively slidably connected to one side of the outer wall of the connecting plate 654.

[0033] Adopting the above scheme: During the movement of the elastic impact rod 655, it will impact the outer wall of the filter rack net 62, causing the filter rack net 62 to vibrate, preventing the centrifugal force from causing the impurity particles to adhere to the inner wall of the filter rack net 62 again when the screw rod 633 drives the impurity particles to descend. The vibration breaks the adhesion force between the impurity particles and the surface of the filter rack net 62, ensuring the cleanliness of the surface of the filter rack net 62.

[0034] Working principle and usage process of the present invention: Pour the bromination reaction liquid into the interior of the backwashing shell 1 through the water inlet pipe 4. The bromination reaction liquid flows through the filter rack net 62, causing impurity particles to stay on the inner wall of the filter rack net 62. The filtered bromination reaction liquid is discharged outward through the drain pipe 5, thereby obtaining the bromination reaction liquid with impurities removed. When the pressure at the inlet and the pressure at the outlet reach the set value, it can be observed through the pressure gauge 641, and no more bromination reaction liquid is injected. Inject the backwashing water into the interior of the annular shell 646 through the elbow 642. The backwashing water enters the interior of the water sprayer 648 through the annular shell 646, and the backwashing water is discharged outward through the water spray openings provided on the water sprayer 648, thereby performing backwashing work on the impurity particles adhering to the filter holes of the filter rack net 62. During the backwashing process, the impurity particles are washed off and stay on the outer wall of the screw rod 633, preventing the particles from adhering to the other side of the inner wall of the filter rack net 62 due to the backwashing water flow. This can avoid the contamination of the filter rack net 62 and keep it clean for a long time. The cleaning effect of the filter rack net 62 is improved. At the same time, the rotating shaft 632 drives the screw rod 633 and the plugging plate 634 to rotate. During the rotation of the screw rod 633, the impurity particles staying on the outer wall of the screw rod 633 can be moved downward. At this time, the plugging plate 634 no longer plugs the double-headed pipe 636, and when the sewage discharge valve 637 is opened, the impurity particles moved to the bottom can be discharged outward through the double-headed pipe 636.

[0035] When the rotating shaft 632 rotates, it drives the round sleeve 643 and the bent rod 644 to rotate. The bent rod 644 drives the rotating plate 645 and the annular shell 646 to rotate. The annular shell 646 drives the water sprayer 648 to rotate. The four water sprayers 648 rotate and spray around the outer wall of the filter rack net 62, and the backwashing water can be evenly sprayed onto the entire surface of the filter rack net 62, effectively removing the impurity particles adhering to the grid. The rotating spray can avoid the water flow concentrating at a certain position and ensure that all parts of the filter rack net 62 can be fully cleaned. When the backwashing water impacts the outer wall of the filter rack net 62, it will first contact the outer wall of the protective net 653, thereby reducing the impact force generated by the discharge of the backwashing water and preventing the impact force from being too large and causing damage to the filter rack net 62 by the rotating screw rod 633.

[0036] When the backwashing water impacts the protective net 653, the generated impact force causes the protective net 653 and the flexible ring 652 to undergo arc deformation. The flexible ring 652 undergoes arc deformation when subjected to the impact force, and this deformation can play a buffering role, reducing the damage to other components caused by the direct impact force. When the flexible ring 652 deforms, it will squeeze the telescopic rod 651. The movable end of the telescopic rod 651 drives the connecting plate 654 to move, and the connecting plate 654 drives the elastic impact rod 655 to move. During the movement of the elastic impact rod 655, it will impact the outer wall of the filter rack net 62, causing the filter rack net 62 to vibrate, preventing the centrifugal force generated when the screw rod 633 drives the impurity particles to descend from causing the impurity particles to adhere to the inner wall of the filter rack net 62 again. The vibration breaks the adhesion force between the impurity particles and the surface of the filter rack net 62, ensuring the cleanliness of the surface of the filter rack net 62. Since the filter holes of the filter rack net 62 are smaller than the round holes of the protective net 653, when there are overly small impurity particles moving to the outside of the filter rack net 62, they will not get stuck between the protective net 653 and the filter rack net 62, which helps to maintain the smooth and efficient operation of the filtration system.
