DETAILED DESCRIPTION

[0029] In order to more clearly understand the purpose, technical solutions and advantages of the present application, the present application is described and illustrated below in conjunction with the accompanying drawings and embodiments.

[0030] See also Figures 1 to 7 The present invention provides a technical solution: a sewage treatment disinfection device, comprising a regulating pipe 5, wherein a first valve 7 and a second valve 8 are installed on the inner wall of the regulating pipe 5, so that a cavity is formed on the inner wall of the regulating pipe 5, and the two ends of the regulating pipe 5 are respectively connected to a disinfection tank 1 and a water inlet pipe 4, and further comprising:

[0031] The adding mechanism includes a containing component, a lifting component and a fixed frame 14, wherein a baffle 29 is slidably installed on the inner wall of the fixed frame 14, and a second slide bar 30 is symmetrically installed on the lower end surface of the baffle 29; when sewage enters the cavity, the lifting component drives the baffle 29 to move downward through the second slide bar 30 according to the change in the amount of sewage, and the gap between the baffle 29 and the fixed frame 14 will gradually increase. At this time, the disinfectant inside the containing component enters the cavity, completing the adding work of the disinfectant, and then discharged into the disinfection tank 1;

[0032] The lifting assembly includes a support rod 20, a second round rod 21 is rotatably mounted on the upper end surface of the support rod 20, connecting rods 16 are symmetrically mounted at both ends of the second round rod 21, sliding grooves 19 are symmetrically opened at both ends of the connecting rod 16, and the inner walls of the sliding grooves 19 are respectively slidably mounted with a first round rod 17 and a third round rod 22, the third round rod 22 is fixedly connected to the second slide rod 30, a first slide rod 18 is rotatably mounted on the outer wall of the first round rod 17, and a floating block 28 is mounted on the lower end surface of the first slide rod 18 through the regulating pipe 5; when the sewage level rises, the floating block 28 rises, the connecting rod 16 rotates with the second round rod 21 as the rotating 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, such as Figure 6 As shown, a drain tube 26 is installed on the lower end surface of the fixed frame 14 through the regulating tube 5, a ball 27 is installed inside the drain tube 26, and the drain tube 26 is installed on the inner wall of the regulating tube 5 away from the fixed frame 14. The opening diameter of the connection between the fixed frame 14 and the drain tube 26 is smaller than the diameter of the ball 27. The ball 27 is hollow inside. The drain tube 26 is composed of two obliquely installed fixing plates, each of which is provided with a plurality of through holes, and the overall shape is narrower at the top and wider at the bottom.

[0034] The interior of the ball 27 is hollow, so it can move up and down according to the change of water level. Since the collet 26 is narrow at the top and wide at the bottom, the space is large enough for the ball 27 to move smoothly. When the water flow hits the ball 27, the ball 27 rotates to prevent the disinfectant from sticking to the outer wall of the ball 27, and the collet 26 can slow down the water flow to prevent it from hitting the floating block 28.

[0035] Further, such as Figure 6As shown, the containing assembly includes a second cylinder 13 connected to a fixed frame 14, the inner wall of the second cylinder 13 is sleeved with a first cylinder 12, the outer wall of the first cylinder 12 away from the second cylinder 13 is connected to a medicine inlet pipe 10, and the inner wall of the first cylinder 12 is installed with a third valve 9;

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

[0037] Further, such as Figure 3 As shown, the outer wall of the fixed frame 14 is symmetrically mounted with an electric telescopic rod 15, and the output end of the electric telescopic rod 15 is mounted with a support plate 11, and the support plate 11 is fixedly mounted on the outer wall of the first cylinder 12;

[0038] When the proportion of disinfectant needs to be adjusted due to different degrees of sewage pollution, the electric telescopic rod 15 contracts or extends to drive 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 control the dosage of the disinfectant.

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

[0040] The water outlet pipe 2 can allow the sterilized water in the sterilizing tank 1 to flow out.

[0041] Further, such as Figure 6 As shown, a groove is provided on the inner wall of the regulating tube 5 corresponding to the floating block 28;

[0042] When the floating block 28 rises in the regulating tube 5, the floating block 28 will enter the groove as the water level rises, which can prevent the mixed liquid in the regulating tube 5 from not being full and the disinfectant from flowing out completely.

[0043] Further, as shown in the figure, the connection between the second round rod 21 and the connecting rod 16 is close to the third round rod 22, and the distance between the second round rod 21 and the first round rod 17 is greater than the distance between the second round rod 21 and the third round rod 22;

[0044] When the connecting rod 16 rotates with the second round rod 21 as the rotating axis, due to the different lengths of the two ends of the connecting rod 16, the connecting rod 16 moves toward the first round rod 17 The side is greater than the side toward the third round rod 22, which can enable the floating block 28 to rise to the groove and the baffle 29 to drop completely.

[0045] Further, such as Figure 1 As shown, a support frame 6 is installed on the outer wall of the sterilizing tank 1, and the support frame 6 is installed on the outer wall of the regulating tube 5 away from the side of the sterilizing tank 1;

[0046] The support frame 6 supports the adjustment tube 5 .

[0047] Furthermore, the water inlet pipe 4 is connected to a plurality of connecting pipes 3 on the side away from the regulating pipe 5, and the diameters of the connecting pipes 3 and the water inlet pipe 4 are smaller than the diameter of the regulating pipe 5;

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

[0049] Furthermore, 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 so that they can cooperate quickly to complete the disinfection work.

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

[0051] The servo motor 23 rotates to drive the fourth round rod 24 to rotate, and the fourth round rod 24 drives the stirring rod 25 to rotate, thereby improving the disinfection efficiency.

[0052] Working principle:

[0053] Step 1: After the external power supply and controller are connected, the sewage pipe is connected through the connecting pipe 3, and the medicine inlet pipe 10 is connected to the disinfectant supply pipe (liquid chlorine is used as an example of the disinfectant). At this time, the third valve 9 is controlled to be opened. 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 inside the first cylinder 12 and the second cylinder 13. Then the second valve 8 is controlled to open a certain angle, so that the sewage level 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 decelerate the sewage, so that the water level inside the regulating pipe 5 rises slowly to prevent impact on the floating block 28. At this time, since the first valve 7 is closed, the sewage water level 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 bar 18 to rise. Figure 4As shown, the first slide bar 18 drives the first round rod 17 to rise, and the first round rod 17 drives the connecting rod 16 to rise through the slide groove 19, and the connecting rod 16 rotates with the second round rod 21 as the rotating axis. At this time, the connecting rod 16 drives the third round rod 22 to descend through the slide groove 19 away from the side of the first round rod 17, and the third round rod 22 drives the second slide bar 30 to descend, and the second slide bar 30 drives the baffle 29 to descend. At this time, the baffle 29 and the fixed frame 14 are no longer in contact, and the disinfectant flows out from the gap between the baffle 29 and the fixed frame 14 and enters the inside of the regulating pipe 5, so that the amount of disinfectant added changes with the water level, which can prevent excessive or insufficient situations, and the disinfectant and sewage flow at the same time, which can make them better mixed.

[0054] Step 2: When the sewage fills the regulating pipe 5, the ball 27 blocks the bottom of the fixed frame 14 to prevent the sewage from entering 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 regulating pipe 5.

[0055] Step 3: When the disinfectant has completely entered the regulating pipe 5, the first valve 7 is opened, the sewage and disinfectant mixture flows into the disinfection tank 1, the floating block 28 descends, and the baffle 29 abuts against the fixed frame 14 again, completing the closure. At this time, the third valve 9 is opened, and the disinfectant is re-injected;

[0056] When the mixed liquid in the regulating tube 5 enters the disinfection tank 1, the servo motor 23 is controlled to rotate, driving the fourth round rod 24 to rotate, and the fourth round 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 for many times to mix the disinfectant and sewage in batches, which can prevent the subsequent disinfectant from diffusing too slowly and affecting the disinfection efficiency. When the remaining sewage is not enough to fill the regulating pipe 5, the baffle 29 will drop to a certain height according to the sewage water 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 drops, so that the baffle 29 abuts against the fixed frame 14 again to complete the closure. The disinfectant can be adjusted according to the water volume to prevent excessive addition of disinfectant. Finally, the sewage that has been disinfected flows out from the outlet pipe 2.

[0058] Step 5: When it is necessary to disinfect 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 retract. 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 that sewage with different pollution degrees can be disinfected.
