Description

Technical Field

[0001] The present invention relates to the technical field of sewage disinfection, and specifically relates to a disinfection device for sewage treatment. Background Art

[0002] With the increasingly severe water resource problems, sewage treatment has become an important link in urban environmental protection and water resource reuse. As the last process of sewage treatment, the main purpose of sewage disinfection is to kill pathogenic microorganisms in water to ensure that the water quality meets the discharge standards or is available for reuse.

[0003] However, due to the volatility of the sewage volume, the existing sewage disinfection devices usually adopt manual addition or semi-automatic addition methods in actual applications. This means that the operator needs to manually adjust the dosage of the disinfectant according to experience or monitoring data. This approach has obvious deficiencies. Due to the frequent fluctuation of the water volume, manual adjustment is likely to result in too much or too little dosage of the disinfectant. Excessive addition will not only lead to an increase in operating costs but also cause an unnecessary burden on the environment. At the same time, if the addition is insufficient, it will result in incomplete sewage disinfection. Summary of the Invention

A baffle is slidably installed on the inner wall of the fixed frame, and second sliding rods are symmetrically installed on the lower end face of the baffle; when sewage enters the cavity, the lifting component drives the baffle to move downward through the second sliding rods according to the change of the sewage volume, and the gap between the baffle and the fixed frame will gradually become larger. At this time, the disinfectant inside the containing component enters the cavity, completing the addition of the disinfectant, and then is discharged into the disinfection tank;

The third round rod is fixedly connected with the second sliding rod, and a first sliding rod is rotatably installed on the outer wall of the first round rod. The lower end face of the first sliding rod penetrates through the adjustment pipe and is installed with a floating block; when the sewage liquid level rises, the floating block rises, and the connecting rod rotates with the second round rod as the rotation axis. The side of the connecting rod away from the floating block drives the third round rod to descend.

[0008] Preferably, a leakage cylinder is installed on the lower end surface of the fixed frame through the regulating tube, a ball is installed inside the leakage cylinder, and the leakage cylinder is installed on the inner wall of the regulating tube away from the fixed frame.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention is provided with an adding mechanism. When sewage enters the regulating pipe, the floating block rises and drives the first round rod to rise through the first sliding rod. The first round rod drives the connecting rod to rise. The connecting rod rotates with the second round rod as the rotating axis. At this time, the connecting rod drives the third round rod to descend away from the side of the first round rod. The third round rod 22 drives the second sliding rod to descend. The second sliding rod drives the baffle to descend. At this time, the baffle and the fixed frame are no longer in contact.

[0029] To more clearly understand the purpose, technical solution and advantages of the present application, the present application will be described and illustrated below with reference to the drawings and embodiments.

[0030] Please refer to Figures 1 to 7 , the present invention provides a technical solution: a disinfection device for sewage treatment, including an adjustment pipe 5, a first valve 7 and a second valve 8 are installed on the inner wall of the adjustment pipe 5 to form a cavity on the inner wall of the adjustment pipe 5. The two ends of the adjustment pipe 5 are respectively communicated with a disinfection tank 1 and a water inlet pipe 4, and further includes:

[0031] An adding mechanism, including a containing component, a lifting component and a fixing frame 14. A baffle 29 is slidably installed on the inner wall of the fixing frame 14, and second sliding rods 30 are symmetrically installed on the lower end face of the baffle 29; when sewage enters the cavity, the lifting component drives the baffle 29 to move downward through the second sliding rods 30 according to the change of the sewage volume. The gap between the baffle 29 and the fixing frame 14 will gradually become larger. At this time, the disinfectant inside the containing component enters the cavity, completes the addition of the disinfectant, and then is discharged into the disinfection tank 1;

[0032] The lifting component includes a support rod 20. A second round rod 21 is rotatably installed on the upper end face of the support rod 20. Connecting rods 16 are symmetrically installed at both ends of the second round rod 21. Chute 19 is symmetrically opened at both ends of the connecting rod 16, and a first round rod 17 and a third round rod 22 are respectively slidably installed on the inner wall of the chute 19. The third round rod 22 is fixedly connected to the second sliding rod 30. A first sliding rod 18 is rotatably installed on the outer wall of the first round rod 17. A floating block 28 is installed at the lower end face of the first sliding rod 18 through the adjustment pipe 5; when the sewage liquid level rises, the floating block 28 rises, the connecting rod 16 rotates with the second round rod 21 as the rotation axis, and the side of the connecting rod 16 away from the floating block 28 drives the third round rod 22 to descend.

[0033] Further, as Figure 6 shown, a leakage cylinder 26 is installed through the adjustment pipe 5 on the lower end face of the fixing frame 14. A spherical ball 27 is installed inside the leakage cylinder 26. The side of the leakage cylinder 26 away from the fixing frame 14 is installed on the inner wall of the adjustment pipe 5. The opening diameter at the connection between the fixing frame 14 and the leakage cylinder 26 is smaller than the diameter of the spherical ball 27. The inside of the spherical ball 27 is hollow. The leakage cylinder 26 is composed of two inclined fixing plates, and each plate is provided with a plurality of through holes, presenting a shape that is narrower at the upper part and wider at the lower part;

[0034] The inside of the spherical ball 27 is hollow, so it can move up and down according to the water level change. Since the overall shape of the leakage cylinder 26 is narrower at the upper part and wider at the lower part, the larger space enables the spherical ball 27 to move smoothly. When the water flow impacts the spherical ball 27, the spherical ball 27 rotates to prevent the disinfectant from adhering to the outer wall of the spherical ball 27, and the leakage cylinder 26 can slow down the water flow to prevent it from impacting the floating block 28.

[0035] Further, as Figure 6As shown, the storage component includes a second cylinder 13 communicating with the fixed frame 14. A first cylinder 12 is sleeved on the inner wall of the second cylinder 13. A medicine inlet pipe 10 is communicated with the outer wall of the first cylinder 12 on the side far from the second cylinder 13. A third valve 9 is installed on the inner wall of the first cylinder 12;

[0036] The third valve 9 enables the disinfectant to enter the interiors of the first cylinder 12 and the second cylinder 13 through the medicine inlet pipe 10.

[0037] Further, as Figure 3 shown, symmetrically installed on the outer wall of the fixed frame 14 are electric telescopic rods 15. The output ends of the electric telescopic rods 15 are installed with support plates 11, and the support plates 11 are fixedly installed on the outer wall of the first cylinder 12;

[0038] When it is necessary to adjust the proportion of the disinfectant due to different degrees of sewage pollution, the electric telescopic rods 15 drive the first cylinder 12 to move inside the second cylinder 13 through the support plates 11 by contracting or extending, so as to change the relative positions between the first cylinder 12 and the second cylinder 13, and further adjust the internal volume to control the dosage of the disinfectant.

[0039] Further, as Figure 1 shown, a water outlet pipe 2 is installed on the outer wall of the disinfection tank 1;

[0040] The water outlet pipe 2 enables the water that has been disinfected in the disinfection tank 1 to flow out.

[0041] Further, as Figure 6 shown, a groove is opened on the inner wall of the adjusting pipe 5 corresponding to the floating block 28;

[0042] When the floating block 28 rises in the adjusting pipe 5, as the water level rises, the floating block 28 will enter the groove, which can prevent the situation that the disinfectant flows out completely before the mixed liquid in the adjusting pipe 5 is full.

[0043] Further, as shown, the connection part of the second round bar 21 and the connecting rod 16 is close to the third round bar 22, and the distance from the first round bar 17 is greater than the distance from the third round bar 22;

[0044] When the connecting rod 16 rotates with the second round bar 21 as the rotation axis, due to the different lengths at both ends of the connecting rod 16, the moving stroke of the connecting rod 16 toward the side of the first round bar 17 is greater than that toward the side of the third round bar 22, which can enable the floating block 28 to rise to the groove and then the baffle 29 to drop completely.

[0045] Further, as Figure 1 shown, a support frame 6 is installed on the outer wall of the disinfection tank 1. The side of the support frame 6 far from the disinfection tank 1 is installed on the outer wall of the adjusting pipe 5;

[0046] The support frame 6 supports the adjusting pipe 5.

[0047] Further, several connecting pipes 3 are connected to the side of the water inlet pipe 4 away from the regulating pipe 5, and the diameters of the connecting pipe 3 and the water inlet pipe 4 are smaller than the diameter of the regulating pipe 5;

[0048] The connecting pipe 3 can connect the sewage from different pollution sources. Since the diameter of the regulating pipe 5 is larger than that of the water inlet pipe 4, when the sewage enters the regulating pipe 5 from the water inlet pipe 4, the flow rate slows down.

[0049] Further, the first valve 7, the second valve 8 and the third valve 9 are all solenoid valves, and a water level sensor (not shown in the figure) is installed in the regulating pipe 5; when the sewage is full, it is convenient to control the opening and closing of the relevant valves to make them cooperate quickly to complete the disinfection work.

[0050] Further, as Figure 5 shown, a servo motor 23 is installed on the upper end surface of the disinfection tank 1, the output shaft of the servo motor 23 penetrates through the disinfection tank 1 and is fixedly installed with a fourth round rod 24, and a plurality of stirring rods 25 are uniformly installed on the outer wall of the fourth round rod 24;

[0051] The rotation of the servo motor 23 drives the rotation of the fourth round rod 24, and the fourth round rod 24 drives the rotation of the stirring rod 25 to improve the disinfection efficiency.

[0052] Working principle:

[0053] The first step: After connecting the external power supply and the controller, connect the sewage pipe through the connecting pipe 3, and connect the medicine inlet pipe 10 to the disinfectant supply pipeline (taking liquid chlorine as an example for the disinfectant). At this time, control the third valve 9 to open. At this time, the disinfectant enters the first cylinder 12 and the second cylinder 13 through the third valve 9, and is blocked by the baffle 29 at the same time. Then the third valve 9 is closed. At this time, there is a certain amount of disinfectant in the first cylinder 12 and the second cylinder 13. Then control the second valve 8 to open at a certain angle, so that the sewage slowly enters the regulating pipe 5 from the connecting pipe 3 through the water inlet pipe 4. At the same time, the leakage cylinder 26 will also slow down the sewage, so that the water level in the regulating pipe 5 rises gently, preventing the impact on the floating block 28. At this time, since the first valve 7 is closed, the water level of the sewage in the cavity rises, driving the floating block 28 and the ball 27 to rise. When the floating block 28 rises, it drives the first slide rod 18 to rise, as Figure 4As shown in the figure, the first sliding rod 18 drives the first circular rod 17 to rise. The first circular rod 17 drives the connecting rod 16 to rise through the sliding groove 19. The connecting rod 16 rotates with the second circular rod 21 as the rotation axis. At this time, the side of the connecting rod 16 away from the first circular rod 17 drives the third circular rod 22 to descend through the sliding groove 19. The third circular rod 22 drives the second sliding rod 30 to descend, and the second sliding rod 30 drives the baffle 29 to descend. At this time, the baffle 29 no longer abuts against the fixed frame 14, and the disinfectant flows out from the gap between the baffle 29 and the fixed frame 14 and enters the adjusting pipe 5, so that the amount of disinfectant added changes with the water level, which can prevent the situation of over - addition or under - addition. And the disinfectant and sewage flow simultaneously, which can make them mix better.

[0054] Step 2: When the sewage fills the adjusting pipe 5, at this time, the spherical ball 27 blocks the lower part of the fixed frame 14 to prevent the sewage from entering the inside of the fixed frame 14. At the same time, the floating block 28 enters the groove. At this time, the baffle 29 is fully opened, and the disinfectant enters the adjusting pipe 5.

[0055] Step 3: When all the disinfectant enters the adjusting pipe 5, at this time, the first valve 7 is opened, and the mixture of sewage and disinfectant flows into the disinfection tank 1. The floating block 28 descends, making the baffle 29 abut against the fixed frame 14 again to complete the sealing. At this time, the third valve 9 is opened to re - inject the disinfectant;

[0056] After the mixture in the adjusting pipe 5 enters the disinfection tank 1, control the servo motor 23 to rotate, drive the fourth circular rod 24 to rotate, and the fourth circular rod 24 drives the stirring rod 25 to rotate, so that the sewage and the disinfectant are fully mixed.

[0057] Step 4: Repeat the above steps multiple times to mix the disinfectant and sewage in batches, which can avoid the subsequent slow diffusion of the disinfectant and affect the disinfection efficiency. And when the remaining amount of sewage is not enough to fill the adjusting pipe 5, at this time, the baffle 29 will drop a certain height according to the sewage level, and part of the disinfectant will remain inside the first cylinder 13 and the second cylinder 12. When the first valve 7 is opened, the floating block 28 descends, making the baffle 29 abut against the fixed frame 14 again to complete the sealing, which can realize the adjustment of the disinfectant according to the water volume and prevent the over - addition of the disinfectant. Finally, the disinfected sewage flows out from the water outlet pipe 2.

[0058] Step 5: When disinfecting sewage from different pollution sources, if the pollution degree of the sewage changes at this time, the electric telescopic rod 15 can be controlled to extend or contract. The electric telescopic rod 15 drives the first cylinder 12 to move inside the second cylinder 13 through the support plate 11, thereby changing the relative position between the first cylinder 12 and the second cylinder 13, and then adjusting the internal volume to complete the adjustment of the dosage of the disinfectant, so as to disinfect sewage with different pollution degrees.
