Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment equipment technology, and in particular to the chlorine dioxide disinfectant dosing structure. Background Technology

[0002] Chlorine dioxide is internationally recognized as the only highly effective disinfectant among chlorine-containing disinfectants. It boasts advantages such as high efficiency, broad spectrum, non-toxicity, ease of use, and low cost. It can kill all microorganisms, including vegetative bacteria, bacterial spores, fungi, mycobacteria, and viruses. Chlorine dioxide has a strong adsorption and penetration ability to microbial cell walls, effectively oxidizing intracellular enzymes containing sulfhydryl groups and rapidly inhibiting microbial protein synthesis, thus destroying microorganisms. Under normal conditions, chlorine dioxide is a strong oxidant, not a chlorinating agent. After use, it only produces oxides, not chlorinated organic matter, and its bactericidal effect is stronger than that of currently widely used chlorine-containing disinfectants. It also has no corrosive effect on equipment and can be widely used in wastewater disinfection to reduce or mitigate water pollution and improve the living environment.

[0003] To address the issue of disinfectants failing to fully mix with wastewater in the disinfection tank, our company researched the chlorine dioxide disinfectant dosing structure disclosed in patent number CN202021646446.9. This design involves creating multiple layers of discharge holes in the dosing pipe, allowing the disinfectant to be discharged from each layer's discharge holes. The dosing method has been changed from single-point dosing to longitudinal multi-point dosing, thus enabling the disinfectant to fully mix with wastewater at each level in the disinfection tank. This improves the stability of the effluent quality from the disinfection tank and reduces disinfectant consumption. However, in actual implementation, it was found that the water level in the disinfection tank would change due to various reasons. When the water level in the disinfection tank dropped, the discharge hole at the top of the dosing pipe would be exposed to the air, causing chlorine dioxide disinfectant to be discharged from the exposed discharge hole. This would result in the chlorine dioxide disinfectant coming into direct contact with the air in the working environment, damaging the working environment. It would also cause a large amount of chlorine dioxide disinfectant to flow to the surface of the disinfection tank, resulting in an excessively high concentration of disinfectant in the upper layer of water and a relatively insufficient concentration in the middle and lower layers. This would disrupt the uniform mixing effect that should be achieved by vertical multi-point dosing, ultimately affecting the stability of the effluent water quality.

[0004] Based on this, the applicant is considering designing a dynamically adjustable chlorine dioxide disinfectant dosing structure. Utility Model Content

[0005] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is: how to provide a dynamically adjustable chlorine dioxide disinfectant dosing structure.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] The chlorine dioxide disinfectant dosing structure includes a dosing pipe extending into the disinfection tank, with several layers of discharge holes longitudinally arranged along the dosing pipe. It also includes a floating component that rises and falls synchronously with the water level in the disinfection tank. The floating component includes a shielding part located outside the dosing pipe, which is used to shield the discharge holes that are exposed above the water surface.

[0008] The working principle and advantages of the chlorine dioxide disinfectant dosing structure in this technical solution are as follows:

[0009] When the water level in the disinfection tank rises or falls, the floating component and its shielding part rise and fall synchronously with the water level. When the water level in the disinfection tank drops to the point where the discharge hole at the top of the dosing pipe is exposed, the shielding part can block the discharge hole exposed above the water surface, preventing the chlorine dioxide disinfectant in the dosing pipe from being discharged from the discharge hole exposed above the water surface. The floating component can dynamically block the discharge hole exposed above the water surface, avoiding the problem of excessively high concentration in the upper layer and insufficient concentration in the middle and lower layers caused by a large amount of chlorine dioxide disinfectant being discharged from the discharge hole exposed above the water surface, thus ensuring that the chlorine dioxide disinfectant is evenly mixed with each layer of water.

[0010] It can prevent chlorine dioxide from being directly discharged into the air and causing pollution to the working environment; and the floating parts do not require external power, but rely solely on buoyancy and water level linkage, resulting in low maintenance costs and suitability for long-term operation in sewage treatment scenarios.

[0011] Furthermore, the shielding part is a shielding cylinder, which is slidably sleeved on the outer wall of the dosing pipe.

[0012] Furthermore, a guide groove is provided on the outer wall of the dosing pipe, and a guide strip that cooperates with the guide groove is provided on the inner wall of the shielding cylinder.

[0013] Furthermore, the shielding cylinder includes two detachably connected arc-shaped plates.

[0014] Furthermore, the floating component includes a mounting bracket fixedly connected to the shielding portion, and a float is detachably connected to the mounting bracket.

[0015] Furthermore, the mounting bracket includes a connecting plate and two spaced-apart fixing rods, the fixing rods being fixedly connected to the shielding part, and the two ends of the connecting plate being detachably connected to the free ends of the two fixing rods; a floating block mounting space is formed between the two fixing rods and the connecting plate.

[0016] Furthermore, the side wall of the float is provided with a snap-fit ​​groove into which the fixing rod extends.

[0017] Furthermore, a sealing component is detachably connected to the bottom of the dosing pipe.

[0018] Furthermore, the sealing component has a bottom discharge hole.

[0019] Furthermore, a flow-blocking plate is fixedly connected to the sealing component, and the flow-blocking plate is spaced apart above the bottom discharge hole. Attached Figure Description

[0032] Refer to together Figures 1 to 4 This embodiment provides a chlorine dioxide disinfectant dosing structure, including a dosing pipe 100 extending into the disinfection tank, and several layers of discharge holes 110 opened longitudinally along the dosing pipe 100. It also includes a floating component 300, which rises and falls synchronously with the rise and fall of the water level in the disinfection tank. The floating component 300 includes a shielding part located outside the dosing pipe 100, which is used to shield the discharge holes 110 that are exposed above the water surface.

[0033] In this embodiment, when the water level in the disinfection tank rises and falls, the floating component 300 and its shielding part rise and fall synchronously with the water level. When the water level in the disinfection tank drops to the point where the discharge hole 110 at the top of the dosing pipe 100 is exposed, the shielding part can shield the discharge hole 110 exposed above the water surface, preventing the chlorine dioxide disinfectant in the dosing pipe 100 from being discharged from the discharge hole 110 exposed above the water surface. The floating component 300 can dynamically shield the discharge hole 110 exposed above the water surface, avoiding the problem of excessively high concentration in the upper layer and insufficient concentration in the middle and lower layers caused by a large amount of chlorine dioxide disinfectant being discharged from the discharge hole 110 exposed above the water surface, thus ensuring that the chlorine dioxide disinfectant is evenly mixed with each layer of water.

[0034] It can also prevent chlorine dioxide from being directly discharged into the air and causing pollution to the working environment; and the floating part 300 does not require external power, but only relies on buoyancy and water level linkage, resulting in low maintenance costs and adaptability to long-term operation of sewage treatment scenarios.

[0035] Preferably, such as Figure 1 and Figure 2 As shown, the shielding part is a shielding cylinder 310, which is slidably sleeved on the outer wall of the dosing pipe 100. When the outer wall of the dosing pipe 100 slides up and down, the shielding cylinder 310 can effectively shield a section of it from all directions, ensuring the shielding effect on the exposed discharge hole 110.

[0036] Preferably, such as Figure 1 and Figure 2As shown, a guide groove 120 is provided on the outer wall of the dosing pipe 100, and a guide strip 311 that cooperates with the guide groove 120 is provided on the inner wall of the shielding cylinder 310. The guide groove 120 and the guide strip 311 form a sliding fit structure, which restricts the shielding cylinder 310 to move only up and down along the axial direction of the dosing pipe 100, prevents it from rotating circumferentially or swinging laterally, improves the stability of the movement of the shielding cylinder 310, and ensures the shielding effect.

[0037] Preferably, such as Figures 1 to 3 As shown, the shielding cylinder 310 includes two detachably connected arc-shaped plates 312; this facilitates the installation of the shielding cylinder 310 on the dosing pipe 100 or its removal from the dosing pipe 100, thereby improving the efficiency of the installation and maintenance of the shielding cylinder 310; specifically, the arc-shaped plates 312 are provided with flanges at both ends in the circumferential direction, and the flanges are provided with through holes, so that the two arc-shaped plates 312 can be connected by a bolt structure.

[0038] Preferably, such as Figures 1 to 3 As shown, the floating component 300 includes a mounting frame 320 fixedly connected to the shielding part, and a float 340 is detachably connected to the mounting frame 320. The float 340 can provide buoyancy for the floating component 300. The mounting frame 320 connects the float 340 to the shielding part, allowing the shielding part to rise and fall synchronously with the float 340. Since the float 340 is detachably connected to the mounting frame 320, different specifications of float 340 can be replaced according to the specifications of the disinfection pool or other actual conditions. Specifically, the mounting frame 320 is connected to both of the above-mentioned arc plates 312. The mounting frame 320 can be directly welded or detachably connected to the arc plate 312.

[0039] Preferably, such as Figures 1 to 3 As shown, the mounting bracket 320 includes a connecting plate 330 and two spaced-apart fixing rods 321. The fixing rods 321 are fixedly connected to the shielding part. The two ends of the connecting plate 330 are detachably connected to the free ends of the two fixing rods 321. A space for installing float 340 is formed between the two fixing rods 321 and the connecting plate 330. When the two ends of the connecting plate 330 are removed from the two fixing rods 321, it is convenient to directly place the float 340 between the two fixing rods 321. Then, the two ends of the connecting plate 330 are connected to the two fixing rods 321 together, which can restrict the float 340 within the space for installing float 340, making it convenient to install and replace float 340. Specifically, a stud 3211 protrudes from the free end of the fixing rod 321, and a through hole is provided on the connecting plate 330 for the stud 3211 to pass through. A locking bolt 322 is threadedly connected to the free end of the stud 3211, making installation convenient.

[0040] Preferably, such as Figures 1 to 3As shown, the float 340 has a snap-fit ​​groove 341 on its side wall for the fixing rod 321 to extend into; the float 340 has a longitudinally penetrating snap-fit ​​groove 341 on each of its opposite side walls. When the float 340 is connected to the mounting bracket 320, the two fixing rods 321 are respectively inserted into the snap-fit ​​groove 341, so that the float 340 can be stably installed in the installation space of the float 340, and at the same time, it is convenient to disassemble the float 340.

[0041] Preferably, such as Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, a plug 200 is detachably connected to the bottom of the dosing pipe 100; the plug 200 can be removed as a whole to facilitate emptying or flushing the inside of the dosing pipe 100; specifically, the plug 200 is a threaded cap that is threadedly connected to the outer wall of the bottom of the dosing pipe 100, which facilitates connection and disassembly; more specifically, a sealing ring can be provided between the plugs 200 and the plugs 200.

[0042] Preferably, such as Figure 5 , Figure 6 and Figure 7 As shown, the sealing component 200 has a bottom discharge hole 220; as described in the patent mentioned in the background art, the distance between the bottom of the dosing pipe 100 and the bottom of the disinfection tank is 20-50cm; when the bottom discharge hole 220 is provided on the sealing component 200, the dosing pipe 100 can not only perform longitudinal multi-point dosing, but also perform vertical dosing of the disinfection tank water below the bottom of the dosing pipe 100; further improving the mixing effect when adding chlorine dioxide disinfectant.

[0043] Preferably, such as Figure 5 and Figure 7 As shown, a baffle plate 210 is fixedly connected to the sealing component 200. The baffle plates 210 are spaced apart above the bottom discharge hole 220. The baffle plates 210 spaced apart on the bottom discharge hole 220 can prevent the chlorine dioxide disinfectant in the dosing pipe 100 from directly impacting the bottom discharge hole 220, avoiding local high pressure impact, and allowing the chlorine dioxide disinfectant to be discharged more evenly from the bottom discharge hole 220 and the discharge hole 110. Specifically, the baffle plate 210 is a disc with a protrusion at the bottom. The bottom side of the sealing component 200 is provided with a groove that is threadedly connected to the protrusion, which facilitates the installation and removal of the baffle plate 210, and also facilitates the replacement of the baffle plate 210 according to the actual situation.
